The project involves the demolition of the existing 3.82 million gallon (MG) Rawlings Reservoir and the construction of two new 3.0 MG each concrete domestic water tanks within the same site. The proposed project is located at 13331 Foothill Boulevard in an incorporated "island" within the City of Tustin, just west of Newport Boulevard. The area surrounding the site, including a sliver of property along Foothill Boulevard, is within unincorporated Orange County. The proposed project also involves implementation of an off-site storm drain connection. The project's storm drain system would be connected to a new storm drain to be installed in Foothill Boulevard that would extend to an existing storm drain facility along either Hewes Street or Newport Avenue. A construction easement within the area west of the project site is also required to facilitate the excavation needed for the new reservoirs. The IS has been prepared pursuant to the California Environmental Quality Act (CEQA), as amended (Public Resources Code 921000 et seq.), and in accordance with the State CEQA Guidelines (California Code of Regulations 915000 et seq.). Pursuant to Section 15367 of the State CEQA Guidelines, the City of Tustin is the lead agency for the project. The lead agency is the public agency that has the pr incipal responsibility for carrying out or approving a project. The City of Tustin, as the lead agency, shall have the authority for project approval and certification of the accompanying environmental documentation. 1.2 SUMMARY OF FINDINGS Based on the environmental checklist form prepared for the project and supporting environmental analysis, the proposed Rawlings Reservoir Replacement Project would have no impact or less than significant impacts in the following environmental impact areas: Aesthetics, Agriculture, Biological Resources, Cultural Resources, Hydrology and Water Quality, Land Use and Planning, Minerals Resources, Noise, Population and Housing, Public Services. Recreation, and TransportationlTraffic. The proposed project has the potential to have Air Quality, Geology and Soils. Hazards and Hazardous Materials, and Utilities and Services impacts unless the recommended mitigation measures are incorporated into the project. According to the CEQA Guidelines, it is appropriate to prepare a Mitigated Negative Declaration (MND) for the proposed project because, after incorporation of the recommended mitigation measures, potentially significant environmental impacts would be eliminated or reduced to a level considered less than signifi cant. 1.3 PROJECT APPROVAL This IS and proposed MND have been submitted to the appropriate responsible and trustee agencies for review and comment, the County Clerk of Orange County for posting, and made available for public review. The Notice of Intent to Adopt an MND for the project has been posted on the site. All documents referenced in the IS are available for review at the City of Tustin Community Development Department located at 300 Centennial Way. R:\ProjectsITustin\JOO3\IS-122005.doc 1-1 Introduction Resolution No. 06-49 Page 7 of 171 Rawlings Reservoir Replacement Project Initial Study There will be a 30-day public review period for the IS and proposed MND. The review period has been established in accordance with g15073 of the CEQA guidelines. In reviewing the IS and the proposed MND, affected public agencies and the interested public should focus on the sufficiency of the document in identifying and analyzing the potential impacts on the environment and ways in which the significant effects of the project are proposed to be avoided or mitigated.

RIProjects\TustinU0031IS-122005.doc Resolution No. 06-49 Page 8 of 171 1-2 Introduction Rawlings Reservoir Replacement Project Initial Study SECTION 2.0 ENVIRONMENTAL SETTING AND PROJECT BACKGROUND 2.1 EXISTING ENVIRONMENTAL SETTING The project site encompasses approximately 1.7 acres and is located at 13331 Foothill Boulevard approximately 1,000 feet northwest of Newport Avenue. The property is an incorporated City of Tustin island surrounded by areas within unincorporated Orange County. Regional location and local vicinity maps are provided in Exhibits 1 and 2, respectively. The project site is bound by Foothill Boulevard and Foothill High School to the south, an unnamed private road and single family residences to the east, an undeveloped slope and a single family residence to the west, and a single family residence to the north. Exhibit 3 provides an aerial photograph of the project site and surrounding areas. Existing site conditions are depicted on Exhibit 4, and site photographs are provided in Exhibits 5a and 5b. The existing reservoir consists of a rectangular 3.82 MG trapezoidal bottom structure in the northern portion of the site. The reservoir is partially buried and has been cut into the natural, southeast-facing hillside. The existing reservoir was constructed in 1971 and has concrete-block perimeter walls and a wood-framed roof. A concrete-block retaining wall is located along the northern property boundary at the toe of an ascending off-site slope. There are an existing residence and pool upslope from the reservoir. This retaining wall has a reinforced concrete foundation structurally integrated with the parallel northerly wall of the reservoir. A concrete wall and chain-link fence form the eastern project boundary and are adjacent to an unnamed private-access asphalt road. A booster pump station is located in the southern portion of the project site and is housed in a concrete structure. An earthen berm descends from the south side of the reservoir down to the paved driveway and pump station (refer to photographs provided in Exhibits 5a and 5b). The majority of the site contains landscape vegetation with various ornamental trees and shrubs. The understory and open areas on the property are dominated by invasive non-native grass species and barren ground. The most abundant ornamental tree and scrub genus on the project site include oleander (Nerium oleander), acacia (Acacia sp.), Russian thistle (Salso/a tragus), fig, (Ficus sp.), pine (Pinus sp.), pepper tree (Schinus sp.), rhus (Rhus sp.), and gum (Eucalyptus sp.). 2.2 PROJECT BACKGROUND The City of Tustin Water Services Division supplies domestic water to the entire community and adjacent areas and maintains water wells, water main lines, service laterals, hydrants, and water storage facilities. The City's water system is divided into three pressure Zones (1, 2, and 3) and currently provides for 7.83 MG of the total storage from five reservoirs. Before it was taken out of service in 2004, the Rawlings Reservoir provided an additional 3.82 MG of storage for pressure Zones 1 and 2 to meet operational and emergency storage needs. Water storage is a key element of any water distribution system. Reservoirs are constructed to provide water supply during peak periods of the day for fire protection and as a backup for emergency conditions. "Operational storage" is the storage volume required to supply peak system demands above the maximum day demand. "Fire storage" is water needed to provide a rate of flow for a required period of time as identified by the Fire Marshal for the types of development served by the system. "Emergency storage" is the water supply needed at times when other sources of supply are out of service or reduced due to an emergency or repair situation.

Improvement recommendations included increasing the storage of the Rawlings Reservoir. In 1996, an engineering analysis of the Rawlings Reservoir identified several structural deficiencies; demolition and replacement of the existing reservoir was recommended. The City's Public Works Department/Water Services Division evaluated the water supplies and demand and concluded that shutting down the reservoir on a temporary basis would not inhibit the City's ability to provide water to customers. Back-up water supply is available at the Vandenberg Well, Columbus-Tustin Well, and Main Street Facility, each providing approximately 2.0 MG of emergency supply. In November 2004, the City recommended demol ition and replacement of the Rawlings Reservoir. As part of the proposed project, the existing Rawlings Reservoir would be replaced at the same site to increase overall system storage capacity to 13.83 MG. This represents an increase of 2.0 MG of storage compared to previous conditions and would provide adequate system-wide operational, fire, and emergency storage. It should be noted that after the operational and fire- flow storage is depleted, back-up water supplies for emergency purposes are provided from the Vandenberg Well, Columbus-Tustin Well, and Main Street Facility each providing approximately 2.0 MG of emergency supply. The proposed project would provide additional emergency water storage capacity to off-set the need to use these back-up water sources. R:\Projects\Tustin\J003\IS-122005.doc 2-2 Environmental Setting and Project Background Resolution No. 06-49 Page 16 of 171 Rawlings ReseNoir Replacement Project Initial Study SECTION 3.0 PROJECT DESCRIPTION 3.1 INTRODUCTION The proposed project is located at 13331 Foothill Boulevard, just west of Newport Boulevard. With the exception of a sliver of property along Foothill Boulevard, the project site is an incorporated island within the City of Tustin surrounded by unincorporated areas of Orange County. The Rawlings Reservoir Replacement project involves the following components which are described below: (1) demolition of the existing reservoir, (2) construction of two new 3 MG water tanks on site and associated improvements, and (3) construction of off-site storm drain facilities. 3.2 PROJECT CHARACTERISTICS 3.2.1 RESERVOIR DEMOLITION The proposed project includes demolition of the existing 3.82 MG reservoir. During the first stage of demolition, the existing reservoir roof, roof-support columns, perimeter side walls to grade, and the reservoir membrane liner would be removed. Asbestos containing materials have been identified in the existing roof mastic; floor and wall mastic; and in the wall fiberboard. These materials would be removed and disposed of in accordance with applicable procedures established by state and local agencies. In the second phase of demolition, the remaining portion of the existing reservoir would be removed, including the perimeter sidewall below grade elevation, the asphalt liner, and the column bases. Demolition of the existing reservoir is estimated to take approxi mately two months. The existing booster pump station located in the southern portion of the site would be shut down during the demolition and construction phases; however, it would not be removed. The City would provide water to the upper pressure zones through its East Orange County Water District connections. The reservoir structure to be demolished is approximately 52,000 square feet. Equipment to be used for demolition activities includes a crane, a scissor-lift, a backhoe/front-end loader, and a bulldozer. Approximately four dump trucks would be required to haul demolition materials. 3.2.2 NEW RESERVOIR CONSTRUCTION AND ON-SITE IMPROVEMENTS The existing reservoir would be replaced with two partially buried concrete domestic water tanks. The preliminary design of these tanks is depicted in Exhibit 6 and cross-sections are shown on Exhibit 7. The two new 3.0 MG concrete water tanks would be circular with a floor elevation of 273 feet above mean sea level (amsl), seven feet lower than the existing reservoir (280 feet amsl). The new tanks would have a water depth of 30 feet; be 142 feet in diameter; and have an elevation of 307 feet amsl, one foot higher than the existing reservoir. The top of the new tanks would be lower than the existing reservoir's wooden roof structure. The new tanks would be located with one behind the other, and construction of the tanks would be staggered (north tank and then the south tank). Shoring would be placed and the site excavated to approximately seven feet below the existing elevation. The north tank would be buried, with the top three feet above ground. The area behind this tank would be paved with asphalt or concrete to provide access for City vehicles for maintenance and inspection R-\ProJects\TustinIJOO3\lS-122005.doc 3-1 Project Description Resolution No. 06-49 Page 17 of 171 1.3 O A ----------------------------------------------------, I I I I I 1 \ 1 1 1 I I Conceptual Layout Exhibit 6 Rawlings Reservoir Replacement Pmjed ..,m. ra,.ro,, ams C O N 5 U 1 7 I N G nwgon.�,maw.sK.�rs_u ,o+xos.�a 320 1 mu y p Ij 300 PROPOSE03 MG TANK .a m � � 300 300 a QQ PRLP08E030 _..PROPOSED] 'NG TANK •/ , . -- . .:.. � / PROPOSED30MG TANK c� r Db:. 134 l va 0 100 200 0 100 MIO �ui men 0 100 200 SECTION AA 'NOTE: CONCEPTUAL ONLY - LIMITS OF TEMPORARY SLOPES AND LOCATION OF TEMPORARY SHORING IS DEPENDENT ON CURRENT ON-GOING GEOTECHNICAL AND ENGINEERING WORK.

The steel hoop reinforcement in the concrete sidewall and the tendons from the base to the sidewall allow the reservoir to flex, if necessary, without failing. The southern tank would be partially buried, with approximately 26 vertical feet of the tank face exposed on the southwest-facing side. A graded and landscaped slope would be provided around the exposed portion of the front tank. New underground water pipelines and valves would connect the existing booster pump station to each new tank. The existing masonry block wall for the booster pump station would be extended across the full front of the site, adjacent to Foothill Boulevard. On the east and west sides of the project site, new chain-link fencing would be installed to replace the existing chain-link fence. The access gate on the northeastern end of the site would be enlarged to improve access to the tanks. An additional gate may be added to provide access from Foothill Boulevard on the west site of the booster pump station. Concrete sidewalk, curb, and gutter would be constructed along the project site's Foothill Boulevard frontage. Landscaping may consist of native and/or ornamental plants and would be planted along the perimeter of the site. The plant material would be selected to provide view screening of reservoir facilities. The exterior of the exposed portions of the two new concrete replacement tanks would receive appropriate coloration treatment to further screen and blend the facilities into and with the proposed landscaping and surrounding area. Based on the current project design, 20,000 cubic yards of earthwork would be removed from the project site during construction, and 40,000 cubic yards would be used following completion of the reservoir construction for backfill. During reservoir construction the following equipment would be used: a crane, a scissor-lift, a backhoe/front-end loader, and a concrete pump. Concrete and delivery truck trips as well as construction-worker vehicular trips would also occur during construction. It is estimated that there would be 5 truck trips and 12 vehicle trips on an average day. Reservoir construction would take approximately 22 months: site excavation and grading - 2 months; new tank construction - 15 months; site back fill - 1 month: pipeline construction and other appurtenances - 2 months: site paving - 1 month; and clean-up/demobilization - 1 month. 3.2.3 OFF-5ITE PROJECT FEATURES Runoff from the project site would be collected in new on-site storm drain lines that would connect to a new storm drain to be installed in Foothill Boulevard. There are two options under consideration for the storm drain lines within Foothill Boulevard and both options are addressed in this Initial StUdy (refer to Exhibit 8). Option 1 would extend to the west approximately 2,800 feet to the Orange County Flood Control District's (OCFCD) 63-inch reinforced concrete pipe in Hewes Street (OCFCD F07-P06). Option 2 would extend to the east approximately 850 feet to the OCFCD's 6-foot by 6-foot reinforced concrete box along Newport Avenue (OCFCD F13). For each option, the storm drain would be installed in the existing public street right-of-way. It should also be noted that a temporary construction easement is needed west of the project site. The construction easement would extend approximately 60-feet onto private property and is needed to facilitate the excavation needed for the new reservoirs. This area could be used for grading or shoring. Additionally, this easement would be used for temporary construction access.

ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist in Section D below. o Aesthetics o Air Quality o Cultural Resources o Hazards & Hazardous Materials o Land Use/Planning o Noise o Public Services o TransportationlTraffic o Mandatory Findings of Significance o Agriculture Resources o Biological Resources o Geology/Soils o Hydrology/Water Quality o Mineral Resources o Population/Housing o Recreation o Utilities/Service Systems C. DETERMINATION: On the basis of this initial evaluation: o I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. [g] I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. o I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. o I find that although the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated impact" on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described in the attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be add ressed. o I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR OR NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR OR NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, and no further documentation is required. Preparer: Scott Reekstin Title Senior Planner Date Elizabeth A. Binsack, Community Development Director R:\ProjectsITustinU0031IS-122005.doc 4-3 Environmental Checklist From Resolution No. 06-49 Page 25 of 171 Rawlings Reservoir Replacement Project Initial Study D. EVALUATION OF ENVIRONMENTAL IMPACTS Directions 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project-specific factors and general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2) All answers must take into account the whole action involved, including off-site, on-site, cumulative project level, indirect, direct, construction, and operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, and EIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063 (c) (3)(D). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats: however, lead agencies normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and, b) the mitigation measure identified, if any, to reduce the impact to less than significance.

AESTHETICS Would the project; a) Have a substantial adverse effect on a scenic vista? Less Than Significant Impact. The proposed site is surrounded by residential uses to the east, west, and north, and by Foothill Boulevard and Foothill High School to the south. Views of the site looking north from Foothill Boulevard are shown in Photograph 1 in Exhibit 5a. As shown in this photograph, views of the reservoir are obstructed by the booster pump station structure, an existing block wall, and mature site vegetation. Residential uses to the west and north are situated at a higher elevation than the Reservoir. The top of the existing reservoir is at an elevation of 306 feet, while the elevation of property to the west is 320 feet amsl and the property to the north is 330 feet amsl. Because these residences are located at a higher elevation, the primary visual focal point from these residences is of the distant background. The reservoir does not obscure the distant views from these residences. The project site is separated from the residential uses to the east by an unnamed private road. Views of the project site from residential uses to the east are obstructed by existing walls and vegetation on both sides of the unnam ed private road, as shown on Photograph 2 on Exhibit 5a. As shown on Exhibit 7, the proposed water tanks would be partially buried and the height of the structures would be similar to the existing reservoir structure. The new water tanks would not obstruct views from existing vantage points surrounding the project site. The City of Tustin General Plan (Conservation/Open Space/Recreation Element, page 8) does not identify any scenic vistas in the vicinity of the project site. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? No Impact. The project site is developed with the existing reservoir and associated facilities including a booster pump station. There are no scenic resources located within the project site, nor is the project site located within proximity to a designated State Scenic Highway. Therefore, no impacts to scenic vistas are expected. c) Substantially degrade the existing visual character or quality of the site and its surroundings? Less Than Significant Impact. The visual character of the project site and surrounding areas is shown on the photographs provided in Exhibits 5a and 5b. The proposed project includes the demolition of the existing reservoir and the construction of two new water reservoir tanks on the same site. Most of the rear tank and a portion of the front tank would be buried. Additionally, the exposed face of the front tank as well as non-paved areas throughout the site would be landscaped, which would shield views of the site. The exterior of the exposed portions of the two new concrete replacement tanks would receive appropriate coloration treatment to further screen and blend the facilities into and with the proposed landscaping and surrounding area. The visual character of the site as viewed from Foothill Boulevard would not be substantially altered since the concrete wall and the structure housing the booster pump station would remain in place. The roadway improvements (curb, gutter, and sidewalk) on the north side of Foothill R:\ProjectsITustin\JOO3\lS-122005 doc 5-1 Environmental Evaluation Resolution No. 06-49 Page 35 of 171 Rawlings ReseNoir Replacement Project Initial Study Boulevard as well as the additional landscaping would be consistent with similar improvements that existing east of the project site. The views of the site from the west, north, and east are not the primary focus of the viewsheds from these areas and the visual character of the site would not be not be substantially degraded or otherwise substantially altered. d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Less Than Significant Impact. Security lighting currently exists within the southern portion of the project site on the booster pump station. In addition to this lighting, the proposed project would include security lighting at the tank hatches, in the event that emergency night work is required. The lights would be manually controlled, directed downward, and would be on during emergency night work only. No other additional site lighting is proposed. The roofs of the reservoirs where the lights would be located would have an asphalt and gravel coating over the concrete finish. The sides of the reservoirs would have a sprayed gunite-concrete finish. These exterior finishes would not generate any glare effects. It should also be noted that the reservoirs would be partially buried further reducing the potential for glare. Therefore, impacts associated with light or glare would be less than signifi cant. Mitigation Program No significant impacts have been identified and no mitigation is required. Sources .

AGRICULTURAL RESOURCES Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? No Impact. The project site is developed with the existing reservoir and associated facilities including the booster pump station, and is located within an existing developed urban area. Furthermore, the City of Tustin General Plan (Figure COSR-2) and the Farmland Mapping and Monitoring Program (State Department of Conservation, 2002) do not identify any designated farmland on the project site. Therefore, the project will not convert any farmland to non- agricultural use and no impacts would be expected. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact. The project site is not zoned for agricultural use or protected by a Williamson Act Contact. No impact would result. R:\Proi,ects\ Tuslin\J003\IS.122005.doc Resolution No. 06-49 Page 36 of 171 5-2 Environmental Evaluation Rawlings ReseIVoir Replacement Project Initial Study c) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use? No Impact. The project includes the demolition of the existing Reservoir and the construction of two new water tanks on the same site. The project would not involve any changes in the existi ng land use and could not result in conversion of farmland to non-agricultural use. No impacts to agricultural resources are anticipated and no impacts would be expected. Mitigation Program No standard conditions and regulations are applicable and no mitigation measures are required. Sources .

AIR QUALITY Regulatory Setting The proposed project is located in the South Coast Air Basin (SCAB) and is within the jurisdiction of the South Coast Air Quality Management District (SCAQMD) and the California Air Resources Board (CARB). Other important air quality management agencies for the basin include the U.S. Environmental Protection Agency (EPA) and the Southern California Association of Governments (SCAG). The EPA implements the provisions of the Federal Cloan Air Act. This Act establishes ambient air quality standards that are applicable nationwide. In areas that are not achieving the standards, the Clean Air Act requires that plans be developed and implemented to meet the standards. The EPA oversees the efforts in the SCAB and ensures that appropriate plans are being developed and im plemented. SCAQMD and SCAG, in coordination with local governments and the private sector, have developed the Air Quality Management Plan (AQMP) for the SCAB. The AQMP provides the blueprint for meeting state and federal ambient air quality standards. The 2003 AQMP is the current approved applicable air plan. The plan was adopted locally on August 1, 2003, by Ihe governing board of the SCAQMD. CARB adopted the plan as part of the California State Implementation Plan on October 23, 2003. The 2003 AQMP was adopted by the E PA on April 9. 2004. State law mandates the revision of the AQMP at least every three years, and federal law specifies dates certain for attaining criteria pollutant standards and preparing plans to meet them. Under federal law, the SCAB has been designated by the EPA as a non-attainment area for ozone, carbon monoxide, and suspended particulates. The SCAB has met the federal nitrogen dioxide standards for the third year in a row, and, therefore, is qualified for redesignation to attainment. A maintenance plan for nitrogen dioxide is included in the 2003 AQMP. Under California state law. the California Clean Air Act (CCAA) mandates the implementation of a program that will achieve the California Ambient Air Quality Standards (CAAQS), and the Clean Air Act (CAA) mandates the implementation of new air quality performance standards. R:\ProjectsITustin\JOO3\1S-122005,doc 5-3 Environmental Evaluation Resolution No. 06-49 Page 37 of 171 Rawlings Reservoir Replacement Project Initial Study The overall control strategy for the 2003 AQMP is to meet applicable state and federal requirements and to demonstrate attainment with ambient air quality standards. The 2003 AQMP contains short- and long-term measures included in Appendix IV -B of the AQMP. Monitored Air Quality Air quality at any site is dependent on the regional air quality and local pollutant sources. Regional air quality is determined by the release of pollutants throughout the air basin. Estimates for the SCAB have been made for existing emissions. The data indicate that mobile sources are the major source of regional emissions. Motor vehicles (i.e., on-road mobile sources) account for approximately 45 percent of volatile organic compounds (VOC), 63 percent of nitrogen oxide (NOx) emissions, and approximately 76 percent of carbon monoxide (CO) emissions. The SCAQMD has divided the SCAB into 38 air-monitoring areas with a designated ambient air monitoring station representative of each area. The project site is located in the area represented by air quality data measured at the Anaheim Monitoring Station, which is near the intersection of Euclid Street and Lincoln Avenue in the City of Anaheim. Ozone, CO, nitrogen dioxide, PM1O, and PM,.5 conditions measured at the Anaheim Station are representative of the project site. The monitoring data show that ozone and particulate matter (PM1O and PM,.5) are the air pollutants of primary concern in the project area. The State 24-hour concentration standards for PM10 have been exceeded between 8 and 20 days each year over the past four years at the Anaheim Monitoring Station: however, during the same four-year period, the Federal standards for PM10 were not exceeded at the Anaheim station. The federal 24-hour standard for PM,.5 was exceeded one day in both 2001 and 2002, three days in 2003, and was not exceeded at all in 2004 at the Anaheim Monitoring Station. There does not appear to be a noticeable trend in either maximum particulate concentrations or days in the area that exceed the particulate standards. The State 1-hour ozone standard was exceeded between two and fourteen days each year over the past four years at the Anaheim station. The Federal 1-hour ozone standard was exceeded one day and the Federal 8-hour ozone standard was exceeded up to six days over the past four years at the Anaheim Monitoring Station. There does not appear to be a noticeable trend in either maximum ozone concentrations or days in the area that exceed the ozone standards. CO is another important pollutant that is caused mainly by motor vehicles. Currently, CO levels in the project region are in compliance with the State and Federal 1-hour and 8-hour standards. High levels of CO commonly occur near major roadways and freeways. CO may potentially be a continual problem in the future for areas next to freeways and other major roadways. The monitored data indicate that no State or Federal standards were exceeded for CO or NO, at the Anaheim station. a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. The South Coast AQMP discussed above is the air quality plan applicable to the proposed project. This section addresses consistency of the project with the AQMP, and specifically whether the project would interfere with the region's ability to comply with Federal and State air quality standards. A proposed project is considered to be consistent with the plan if it furthers one or more policies and does not obstruct other policies. The Handbook identifies two key indicators of consistency: 5.4 Environmental Evaluation R ",\Prol"'"\T""qocoo~~I,l.OO5do' esolu Ion NO. Uti-4l! Page 38 of 171 Rawlings Reservoir Replacement Project Initial Study (1) Whether the project will result in an increase in the frequency or severity of existing air quality violations, cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the AQMP (except as provided for CO in Section 9.4 for relocating CO hot spots). (2) Whether the project will exceed the assumptions in the AQMP in 2010 or increments based on the year of project buildout and phase. Following is an evaluation of the project with respect to these criteria: . Criterion 1 - Increase in the Frequency or Severity of Violations: Based on the air quality modeling analysis provided under Checklist Item IIl.b below and the SCAQMD thresholds of significance, short-term construction and long-term operation would not result in significant impacts. Short-term construction activities would not increase the frequency or severity of existing air quality violations due to required compliance with SCAQMD Rules and Regulations. Similarly, the emissions from the project are projected to be a fraction of a percentage of the basin-wide emissions. Given that the project involves the replacement of an existing reservoir, there would be negligible long-tf,rm increases in operational emissions resulting from the periodic maintenance of the reservoir and the associated pump station and pipelines. The proposed project would not contribute to the exceedance of any air pollutant concentration standards; thus, the project is found to be consistent with the AQMP for the first criterion. . Criterion 2 - Exceed the Assumptions in the AQMP: SCAG and the SCAQMD jointly prepare the South Coast AQM P. Through this partnershi p, SCAG provides housing and population growth projections, and SCAQMD estimates regional emissions based on the growth forecasts provided by SCAG. The project involves the replacement of an existing reservoir and would provide water supply to existing and planned land uses in the City of Tustin. The project would not represent an expansion of services to meet the demand of land uses not already considered in SCAG local and regional growth forecasts. Therefore, the proposed project would not exceed the assum ptions of the AQMP. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? Less Than Significant With Mitigation Incorporation. Air quality impacts are usually divided into short-term construction and long-term operational impacts. Short-term impacts are the result of demolition, grading, and/or construction operations. Long-term impacts are associated with the long-term operations of the proposed project. In the CEQA Handbook, the SCAQMD has established significance thresholds to assess the regional impact of project-related air pollutant emissions. Table 1 presents these significance thresholds. There are separate thresholds for short-term construction and long-term operational emissions. A project with daily emission rates below these thresholds are considered to have a "less than significant" effect on regional air quality throughout the SCAB. Because the project involves the replacement of an existing reservoir with the same use and would result in negligible changes in long-term emissions from reservoir and related infrastructure maintenance, this analysis focuses on short- term emissions.

Short-Term Construction-Related Impacts Temporary air quality impacts would result from project construction activities. Air pollutants would be emitted by construction equipment and fugitive dust would be generated during demolition of the existing facilities and grading of the site. The air quality analysis assumes various types of equipment would be used during respective phases that will occur sequentially. The estimated type and amount of construction equipment to be used during construction is summarized in Section 3, Project Description. Specific equipment assumed for each phase of construction (Phase I - Demolition, Phase II - Grading, and Phase III - Construction) is identified in the calculation worksheets provided in Appendix A. Asphalt and paving are considered sub-phases under Phase III. Approximately 30 construction workers were assumed to commute to the project site for all three phases based on generation factors within the URBEMIS air quality modeling program (version 2.2) developed by the SCAQMD. Emissions from on-road hauling vehicles disposing of demolition materials and importing/exporting soils during grading were calculated by URBEMIS using the square footage of the existing reservoir to be demolished and cubic yards of soil imported/exported. Demolition The existing reservoir has a volume of 52,000 cubic feet. Demolition of the existing reservoir is projected to occur over a two-month period. Based on the assumptions for equipment and construction workers, and the square footage of structure to be demolished, the peak daily air pollutant emissions during demolition were calculated using URBEMIS. The results are provided in Appendix A and summarized below in Table 2. The datum presented in Table 2 show that the estimated pollutant emissions associated with the demolition of the existing reservoir would not be greater than the significance thresholds established by the SCAQMD in the CEQA Air Quality Handbook and no significant impacts would result.

Cut and fill required for the project is expected to involve export of approximately 20,000 cubic yards and import of approximately 40,000 cubic yards of soil. Ba!ied on the assumptions for equipment and construction workers, and the anticipated amount of cut/fill and soil export/import, the peak daily air pollutant emissions during grading were calculated using URBEMIS. The results are provided in Appendix A and summarized below in Table 3. TABLE 3 GRADING AIR POLLUTANT EMISSIONS Maximum Pollutant Emissions (Ibs/day) Activity CO ROO NO.

The significant impact associated with PM10 emissions is primarily the result of release of dust during grading and transport of soil during export/import. Implementation of Mitigation Measure 3-1 (MM 3-1) would reduce impacts to a level considered less than significant. Construction Construction is the longest phase of the proposed project with duration of approximately 20 months, which includes the architectural coatings and asphalt paving sub-phases during ',he last 2 months. Based on the assumptions for equipment and construction workers, and the R:\Prujects\Tustin\J003\1$-122005.doc 5-7 Environmental Evaluation Resolution No. 06-49 Page 41 of 171 Rawlings Reservoir Replacement Project Initial Study anticipated square footage to be painted or paved, the peak daily air pollutant emissions during construction were calculated using URBEMIS. The results are provided in Appendix A and summarized in Table 4. Delivery of concrete and other construction supplies to the project site would result in emissions that are not accounted for in the URBEMIS model. However, URBEMIS assumes that a single on-road diesel truck round-trip of 20 miles would result in emissions of 0.1 pound (Ib) of CO, 0.1 Ib of ROG, 0.6 Ib of NOx, and 0.1 Ib of PMlO. It was estimated that the proposed project would result in a maximum feasible number of diesel truck round-trip deliveries of 45 during a 10-hour work day (i.e., one delivery every 13 minutes). Delivery or "on-road diesel" emissions have been calculated using the URBEMIS assumptions and are included in Table 4.

Less Than Significant Impact. According to the EPA, some people are much more sensitive than others to air pollutants. Sensitive receptors include children, the elderly, and people with health problems. People with influenza, chronic respiratory and cardiovascular diseases, and the elderly may suffer worsening illness and premature death due to breathing airborne particulate matter. Children may also experience a decline in lung function due to breathing in particulate emissions. Land uses with a high concentration of people with a high sensitivity to airborne particles or other pollutants are considered sensitive receptor locatio!]s. Sensitive receptor locations include primary and secondary schools, hospitals, and convalescent homes. As discussed in Section 2.0, Environmental Setting and Project Background, the project site is surrounded to the north and east by single-family residential land uses, to the south by Foothill Boulevard and Foothill High School, and to the west by a landscaped slope and single-family residential uses. Foothill High School would be considered a sensitive receptor in the immediate project vicinity. The proposed project involves the replacement of an existing water reservoir and would not include uses that would generate substantial long-term pollutant concentrations or expose existing sensitive receptors in the area to such pollutants. Although surrounding uses would experience a temporary increase in some airborne pollutants as a result of the project, this R\ProjectsITuslin\JOO3\IS.122005.doc Resolution No. 06-49 Page 42 of 171 5-8 Environmental Evaluation Rawlings Rese/voir Replacement Project Initial Study increase is not significant per the SCAQMD thresholds and would result in a less than significant impact. e) Create objectionable odors affecting a substantial number of people? Less Than Significant Impact. Construction of the proposed project would result in a short- term source of odor associated with construction activities (e.g., diesel exhaust and paint fumes). However, these potential odors are temporary and would not affect a substantial number of people. The proposed project does not involve a change in land uses or operations on site and would not result in long-term odor impacts on surrounding land uses or people. Although surrounding uses could potentially experience construction-related odors as a result of the project, this increase would not affect substantial numbers of people and would be less than significant. Mitigation Program Mitiaation Measures MM 3-1 The contractor shall comply with all applicable SCAQMD Rules and Regulati<lns including Rule 403. This requirement shall be included on the contractor specifications. A plan to control fugitive dust during the project grading phase through implementation of reasonable available dust control measures shall be prepared and submitted to the City of Tustin Public Works Department. The plan shall specify the fugitive dust control measures to be employed. The plan may include, but shall not be limited to, the following fugitive dust control techniques: . Application of sufficient water prior to initiating any earth movement; . Suspension of grading operations during first and second stage ozone episodes or when winds exceed 25 miles per hour; . Watering portions of the project site undergoing earth moving operations a minimum of three times a day; . Sweeping and/or street cleaning where vehicles exit construction sites; . Installation of bedliners in fill import and export vehicles; . Covering of fill import and export vehicles when carrying bulk material; . Installation of wheel washers where vehicles exit disturbed surface areas onto paved roads. Sources .

BIOLOGICAL RESOURCES Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? No Impact. A large portion of the site contains landscape vegetation, with various ornamental trees and shrubs. The understory and open areas on the property are dominated by invasive non-native grass species and barren ground. The most abundant ornamental tree and scrub genus on the project site include oleander (Nerium oleander), acacia (Acacia sp.), Russian thistle (Salsola tragus), fig, (Ficus sp.), pine (Pinus sp.), pepper tree (Schinus sp.), rhus (Rhus sp.), and gum (Eucalyptus sp.). The project site provides marginal habitat for wildlife other than those animals typically found in a disturbed urban environment. The relative small size of the project site, its proximity to residential land uses, and its isolation from natural open space areas limits the potential for a substantial number of native wildlife species to occur on the project site. The potential for special status plant and wildlife species to occur on the project site is limited by the ornamental vegetation and lack of native habitat present. Therefore, no impacts to candidate, sensitive, or special status species would occur. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? No Impact. The project site primarily contains upland ornamental vegetation; there are no areas within the project site that meet the California Department of Fish and Game (CDFG) jurisdiction pursuant to Section 1603 of the California Fish and Game Code. CDFG uses Section 1603 to regulate activities that substantially affect the bed or bank of streams or lakes. As there is no riparian habitat or other sensitive natural community on site, no impacts would occur. Additionally, based on review of the City's General Plan (Figure COSR-2), the site has not been identified as being in an area with important natural resources (i.e., a sensitive natural community). c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? No Impact. The project site does not meet the Army Corps of Engineers (ACOE) criteria for wetlands and waters of the U.S., and would not be regulated as a wetlands or waters of the U.S. There is no wetland habitat on the project site; therefore, project implementation would not impact federally protected wetlands as defined by Section 404 of the Clean Water Act and the 1987 Corps Manual. 5.10 Environmental Evaluation R.\Proj~s\Tu~ti[1\JOO~\!ii-1n.OO5_doc Resolution NO. Utj-4~ Page 44 of 171 Rawlings Reservoir Replacement Project Initial Study d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? No Impact. The project site provides little habitat for wildlife other than those animals typically found in a disturbed urban environment. The project site is located in a developed urban area and has not been identified as a crucial portion of the migratory path of any animal species. Additionally, there are no natural water sources or habitat for migratory species. No impacts would occur. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. Two tree groups that are identified in the Tustin General Plan as important to the City are eucalyptus windrow and redwood grove. The proposed project would not result in the removal of, or otherwise adversely impact, these tree communities. The proposed project would not conflict with any local policies or ordinances protecting biological resources. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natmal Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? No Impact. The project site is within the County of Orange Central and Coastal Natural Communities Conservation Plan and Habitat Conservation Plan (NCCP/HCP). The NCCP/HCP was adopted by the California Department of Fish and Game (CDFG), U.S. Fish and Wildlife Service (USFWS), and participating agencies (including the City of Tustin) in 1996 to addmss protection and management of coastal sage scrub (CSS) habitat and CSS-obligate species, Hnd other covered habitats and species. The NCCP/HCP mitigates anticipated impacts to those habitats and species, on a programmatic, sub-regional level, rather than on a project-by-project, single species basis. The NCCP/HCP involved the establishment of an approximate 37,000-acre Reserve for the protection of CSS, other upland habitats, the coastal California gnatcatcher, and other species identified in the NCCP/HCP. The project site is not within the NCCP/HCP Reserve, rather it is within a development area identified in the NCCP/HCP. The proposed project would not conflict with the NCCP/HCP. Mitigation Program No significant impacts have been identifi ed and no mitigation is required. Sources .

CULTURAL RESOURCES Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined in ~ 15064.5? No Impact. Cultural resources are places, structures, or objects that are important for scientific, historic, and/or religious reasons to cultures, communities, groups, or individuals. Cultural resources include historic and prehistoric archaeological sites, architectural remains, engineering structures, and artifacts that provide evidence of past human activity. They also include places, resources, or items of importance in the traditions of societies and religions. CEQA Guidel ines Section 15064.5 defines historic resources as any object, building, structure, site, area, place, record, manuscript, or other resource listed or determined to be eligible for listing by the State Historical Resources Commission, a local register of historic resources, or the Lead Agency. Generally, a resource is considered to be "historically significant" if it meets one of the followi ng criteria: . is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage. . is associated with the I ives of important persons in the past. . embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or has yielded, or may be likely to yield, information important in prehistory or history. The project site is not located within the City's Cultural Resources Overlay District and is not the site of any historic resources as noted in Figure COSR-3 in the Tustin General Plan. The Reservoir is not associated in a significant way with important historic events or persons and is not likely to yield important historic information, and therefore, is not considered a historical resource per CEQA guidelines. The project would not cause a substantial adverse change in the significance of any historical resource. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to ~ 15064.5? Less Than Significant Impact. The project site is developed with an existing reservoir and is located within an existing developed urban area. Because the site is already developed and has been disturbed previously, there is little potential that project excavation and grading would encounter buried and undiscovered archaeological resources. The excavation and grading activities associated with the improvements would be conducted in accordance with the City's grading requirements. Although it is not expected that archaeological resources would be encountered, if archaeological resources are discovered during excavation, they are to be handled in accordance with Standard Condition 5-1 (SC 5-1) below. c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less Than Significant Impact. The project site is developed with an existing reservoir and is located within an existing developed urban area. Because the site is already developed and has R\ProjectsITustlnIJOO3\IS-122005.doc Resolution No. 06-49 Page 46 of 171 5-12 Environmental Evaluation Rawlings Reservoir Replacement Project Initial Study been disturbed previously, there is little potential that project excavation and grading would encounter undiscovered paleontological resources. Furthermore, the excavation and grading activities associated with the improvements would be in accordance with the City's grading requirements. Although it is not expected that paleontological resources would be encountered, if paleontological resources are discovered during excavation, they are to be handled in accordance with SC 5-1 below. d) Disturb any human remains, including those interred outside of formal cemeteries? Less Than Significant Impact. The project site is developed with an existing reservoir and is located within an existing developed urban area. Because the site is already developed and has been disturbed previously, there is little potential that project excavation and grading would uncover any human remains. Furthermore, the excavation and grading activities associated ~~ith the improvements would be in accordance with the City's Grading Manual requirements. It is highly unlikely that human remains would be encountered. However, if human remains are discovered during excavation, they are to be handled in accordance with SC 5-1, below. Mitigation Program Standard Conditions and Reaulations SC 5-1 Should any archaeological or paleontological resources be uncovered during gradi ng or excavation activities, these activities shall be diverted to a part of the site away from the find, and an Orange County-certified archaeologist andlor paleontologist shall be contacted by the contractor to: (1) ascertain the significance of the resource, (2) establish protocol with the contractor to protect such resources, (3) ascertain the presence of additional resources, and (4) provide additional monitoring of the site, if deemed appropriate. If human remains are discovered on the site, the Orange County Coroner shall be contacted to examine the remains, and the provisions of Section 15064.5(3) of the CEQA Guidelines shall be followed. These requirements shall be included as notes on the contractor specifications and verified by the Publ ic Works Department prior to issuance of grading permits. Sources .

GEOLOGY AND SOilS Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: I) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. No Impact. The Alquist-Priolo Special Studies Zones Act was signed into law in 1972. In 1994, it was renamed the Alquist-Priolo Earthquake Fault Zoning Act (A-P Act). The primary purpose R:\ProjectsITustinUOO3\1S-122005.doc 5-13 Environmental Evaluation Resolution No. 06-49 Page 47 of 171 Rawlings ReseNoir Replacement Project Initial Study of the Act is to mitigate the hazard of fault rupture by prohibiting the location of structures for human occupancy across the trace of an active fault. The A-P Act requires the State Geologist (Chief of the California Geology Survey) to delineate "Earthquake Fault Zones" along faults that are "sufficiently active" and "well-defined." The boundary of an "Earthquake Fault Zone" is generally about 500 feet from major active faults and 200 to 300 feet from well-defined minor faults. The A-P Act dictates that cities and counties withhold development permits for sites within an Alquist-Priolo Earthquake Fault Zone until geologic investigations demonstrate that the sites are not threatened by surface displacements from future faulting. The project site is not located within a currently designated Alquist-Priolo Earthquake Fault Zone and there are no currently known active or potentially active surface faults at or locally trending toward this site. Therefore, the project would not expose people or structures to adverse effects involving the rupture of a known earthquake fault. ii) Strong seismic ground shaking? Less Than Significant Impact. The project site, as with all of Southern California, could be subject to strong ground shaking in the event of an earthquake. The closest active fault, the Elsinore-Whittier fault, is located approximately 8.5 miles (14 kilometers) southwest of the project site. However, the project does not propose construction of any structures that would encourage frequent use of the site by people for any reason. Ground shaking impacts would be mitigated through compliance with the American Water Works Association (AWWA) Standard D110-95, American Concrete Institute (ACI) Standard 350, and the most current version of the Uniform Building Code. This would safeguard against major structural failures due to a seismic event. Seismic ground shaking impacts are considered less than significant when current standards and standard engi neering practices are used. The proposed project would not expos e people or structures to substantial adverse effects associated with strong seismic ground shaking. iii) Seismic-related ground failure, including liquefaction? Less Than Significant Impact. Liquefaction occurs when groundwater is forced out of the soil as it subsides. This excess water momentarily liquefies the soil, causing an almost complete loss of strength. If this layer is at the surface, its effect is much like that of quicksand for any structure located on it. If the liquefied layer is in the subsurface, the material above it may slide laterally depending on the confinement of the unstable mass. According to the California Division of Mines and Geology, April 15, 1998, Seismic Hazard Zones Map, Orange 7S Quadrangle, this site is not located inside a potential liquefaction-hazard zone. Project site earth materials consist of primarily clayey soils underlain by Miocene age sedimentary bedrock, which is not expected to liquefy. The liquefaction potential on-site is remote. In addition to liquefaction, during a strong seismic event, seismically induced settlement can occur within loose to moderately dense, unsaturated granular soils. Settlement caused by ground shaking is often non-uniformly distributed, which can result in differential settlement. The proposed reservoirs would be located on sedimentary bedrock. Therefore, seismically induced settlement under the tank would be less than Y<-inch to negligible. Seismically-induced differential settlement could be up to half of the total seis mic settlement. Construction of the proposed project would occur in accordance with the current standards and standard engineering practices and impacts would be less than significant. R:\ProjectsITusllnIJOO3\1S-122005.doc Resolution No. 06-49 Page 48 of 171 5-14 Environmental Evaluation Rawlings Reservoir Replacement Project Initial Study iv) Landslides? No Impact. According to the California Division of Mines and Geology, April 15, 1998, Seismic Hazard Zones Map, Orange 7.5' Quadrangle, this site is not located inside an earthquake- induced landslide hazard zone. Additionally, no landslides were identified during site investigations by the engineering geologist. The proposed project would be designed and constructed in accordance with the recommendations found in the project site's geotechnical investigation and with the most current safety standards of the Uniform Building Code and other related codes. With application of these codes and recommendations, construction of the proposed project woul d not impact slope stability. No impacts are expected. b) Result in substantial soil erosion or the loss of topsoil? Less Than Significant Impact. The proposed project would require excavation, grading, and other earthmoving activities, which would expose soils and thereby increase the potential for the erosion or loss of topsoil during construction. Refer to Section VIII, Hydrology and Water Quality, for an evaluation of the proposed project's potential impact on soil erosion. Following construction, the amount of impervious surface on site would be increased, reducing the potential for on-site erosion compared to existing conditions. The project would have a less than significant impact related to soil erosion. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? Less Than Significant with Mitigation. Settlement, liquefaction and landslide potential were addressed in Items Vl.a.iii and Vl.a.iv. Lateral spreading is a function of groundshaking and may occur during an earthquake. Seismic ground-shaking impacts, including lateral spreading, are considered less than significant when current Uniform Building Code standards and standard engineering practices are used. It should also be noted that temporary cut slopes are required for the northern reservoir. During construction these slopes would be stabilized with temporary shoring. After the reservoirs are constructed this area would be backfilled to gentle slopes and the tank walls would support the backfill. The backfill would also buttress the existing retaining wall for the off-site slope which ascends to the residence north of the project site. Mitigation Measures 6-1 and 6-2 require that recommendations outlined in the project geotechnical report be incorporated into the grading plans and would reduce impacts to a level considered less than significant. d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Less Than Significant Impact. The existing reservoir is underlain by sedimentary bedrock of the Miocene age Puente formation that is highly expansive. In accordance with the recommendations found in the project site's geotechnical investigation, the new water tanks would be founded solely on sedimentary bedrock. Although the proposed project would be located on expansive soils, construction of the proposed project would occur in accordance with current standard engineering practices. Impacts would be less than significant and would not create substantial risks to life or property. R\Projects\Tustin\JOO3\IS.122005.doc 5-15 Environmental Evaluation Resolution No. 06-49 Page 49 of 171 Rawlings Reservoir Replacement Project Initial Study e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? No Impact. The proposed project would not involve the use of septic tanks or alternative waste water disposal systems. Mitigation Program Mitiqation Measures MM 6-1 Prior to issuance of a grading permit, the contractor shall submit grading plans that incorporate recommendations of the geologic and soils engineer reports. Compliance with this requirement shall be verified by the Public Works Department. MM 6-2 During construction, geotechnical observation and testing shall be provided by the geotechnical engineer/engineering geologist. Specifically, observation and testing shall occur during shoring installation, overexcavation, compaction of all backfill and/or when unusual geotechnical conditions are encountered. This requirement shall be included on the contractor's specification and verified by the Public Works Department. Sources .

HAZARD AND HAZARDOUS MATERIALS Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Less Than Significant Impact. During the construction phase of the project, there is a limited risk of accidental release of hazardous materials such as gasoline, oil, or other fluids in the operation and maintenance of construction equipment. Compliance with standard State and local construction requirements would reduce the risk of any damage or injury from these potential hazards to a less than significant level. The project, which involves the replacement of a water storage reservoir with two new reservoirs does not include the construction of any uses that would involve the use, storage, or transport of hazardous materials resulting in the risk of release or emission of hazardous emissions. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less Than Significant With Mitigation. An asbestos and lead survey was conducted for the proposed project. The asbestos survey was conducted and recommendations were made in R:\Proj!'!;Cts\Tu~tin\JOOllJ,t).1noo5.doc Resolution NO. uo-4!J Page 50 of 171 5-16 Environmental Evaluation Rawlings Reservoir Replacement Project Initial Study compliance with all regulatory agency requirements including SCAQMD Rule 1403. Based on the results of the survey, there was no presence of materials with lead levels at or above the United States Department of Housing and Urban Development (HUD) Guidelines. Asbestos containing materials (ACMs) were commonly used in a wide variety of building products such as roofing shingles; composite siding; linoleum flooring; acoustic ceiling tiles; furnace and water heater exhaust piping and insulation; glues and mastics; stucco; joint compounds; and composite wallboards prior to 1980. ACMs can be divided into material considered friable (Le., easily crumbled or reduced to powder) and nonfriable. Friable ACMs are regulated as hazardous materials due to the elevated long-term risk of developing lung cancer upon respiratory exposure and must be properly removed prior to renovation or demolition of any structure containing these materials. Asbestos is present in the reservoir's roof mastic, floor and wall mastic, and fiberboard. The ACMs in these compounds are in good to fair condition and are considered nonfriaiJle. However, these materials could become friable if damaged or disturbed. Because exposure to such materials can result in adverse health effects in uncontrolled situations, several regulations and guidelines pertaining to abatement of and protection from exposure to asbestos have been developed for demolition activities. Prior to demolition of the existing reservoir, ACMs would be removed and disposed of by qualified contractors. With implementation of SC 7-1, potential hazards resulting from the removal and disposal of these materials would be reduced to a level considered less than significant. These materials would be removed in accordance with the recommendations of the project's asbestos survey report and the remediation and mitigation procedures established by all federal, state, and local standards. With the application of these recommendations and standards, impacts associated with the release of hazardous materials would be reduced to less than significant. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Less Than Significant Impact. Foothill High School is located south of the project site on the south side of Foothill Boulevard. As discussed under 7.b, during demolition of the existing Reservoir, ACMs found on-site would be removed in accordance with applicable standards. Impacts associated with the release of ACMs would be reduced to less than significant. However, the project does not include the construction of any uses that would involve the use, storage, or transport of hazardous materials resulting in the risk of release or emission of hazardous emissions. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? No Impact. The project is not located on site which is included on a list of hazardous materials sites. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? No Impact. The proposed project is located approximately five miles from John Wayne Airport and is not located within the John Wayne Airport land use plan. The landing flight path of aircraft, however, is near or over the project site location. Generally, if a site is greater than two miles away from an airport and it is not under a direct flight path, then the impact and safety R\Projects\Tuslin\JOO3\1S.1220Q5.doc 5.17 Environmental Evaluation Resolution No. 06-49 Page 51 of 171 Rawlings Reservoir Replacement Project Initial Study threat from the airport is negligible. Safety hazards related to this issue would be less than significant. If) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact. There are no private airstrips identified in close proximity to the proposed project location. The proposed project would not affect nor be affected by private airstrips. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? No Impact. The proposed project involves the continuation of an existing use and would not impair implementation of, or physically interfere with, an adopted emergency response plan or emergency evacuation plan. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? No Impact. The project site is located in an urban area with no wildlands in close proximity. Therefore, the project would not expose people or structures to a significant risk of loss, injury, or death from wildfires. Mitigation Program Standard Conditions and Reoulations SC 7-1 Prior to demolition of the existing reservoir, the contractor shall comply with notification and asbestos removal procedures outlined in SCAQMD Rule 1403 to reduce asbestos-related health risks. SCAQMD Rule 1403 applies to any demolition or renovation activity and the associated disturbance of asbestos- containing material. This requirement shall be included on the contractors' specifications and verified by the Department of Public Works. Mitioation Measures MM7-1 Prior to issuance of a demolition permit, the contractor shall submit an Asbestos Management Program (AMP) to the Public Works Department. The AMP set forth operational and maintenance guidelines to minimize fiber release which may be caused by the proposed project during demolition activities. The AMP shall incorporate recommendations from the Asbestos and Lead Survey report prepared for the project (National Econ, February 2005) and compliance with the this program shall be a requirement included on the contract specifications. Inclusion of these requirements on the specifications shall be verified by the Public Works Department. Sources .

HYDROLOGY AND WATER QUALITY Would the project: a) Violate any water quality standards or waste discharge requirements? f} Otherwise substantially degrade water quality? Less Than Significant Impact. The City of Tustin, including the project site is, within the jurisdiction of the Santa Ana Regional Water Quality Control Board (RWQCB). In addition to the requirements of the RWQCB, the project is subject to requirements of the 1972 Federal W"ter Pollution Control Act, subsequently known as the Clean Water Act (CWA). In 1972, the CWA was amended to require National Pollutant Discharge Elimination System (NPDES) permits for the discharge of pollutants to waters of the United States from any point source. In 1987, the CWA was amended to require that the United States Environmental Protection Agency (EPA) establish regulations for permitting under the NPDES permit program of municipal and industrial stormwater discharges. The regulations require that municipal separate storm sewer system (MS4) discharges to surface waters be regulated by an NPDES permit. The MS4s are designated or used for collecting or conveying stormwater as opposed to wastewater or combined sewage. In January 2002, the RWQCB issued an NPDES permit (Order No. R8-2002-0010) applicable to northern Orange County cities (co-permittees). This permit will regulate storm water and urban runoff discharges from the project site to constructed storm drain systems in the project area. The co-permittees have developed a 2003 Drainage Area Management Plan (DAMP). Pursuant to the CWA Section 402(p), requiring regulations for permitting of certain stormwciter discharges, the State Water Resources Control Board (SWRCB) has issued a statewide genE,ral NPDES Permit for stormwater discharges from construction sites (NPDES No. CAS000002). Under this Construction General Permit (effective March 2003), discharges of stormwater from construction sites with a disturbed area of one or more acres are required to either obtain individual NPDES permits for stormwater discharges or be covered by the Construction General Permit. Coverage under the Construction General Permit is accomplished by completing and filing a Notice of Intent with the SWRCB. Each applicant under the Construction General Permit must ensure that a Stormwater Pollution Prevention Plan (SWPPP) is prepared prior to grading and implemented during construction. The primary objective of the SWPPP is to identify, construct, implement, and maintain best management practices (BMPs) to reduce or eliminate pollutants in stormwater discharges and authorized non-stormwater discharges from the construction site during construction. In compliance with the NPDES program and DAMP, the proposed project would be required to incorporate post-construction BMPs to reduce the amount of pollutants introduced into the stormwater drainage system on a long-term basis. It is anticipated that the proposed project would implement structural BMPs including catch basin inserts/fossil filters and trash racks to remove paper, debris, and sediments before the runoff is discharged to the storm-drain system. A Water Quality Management Plan would be prepared for the project. Implementation of BMPs and compliance with local, state and federal water quality regulations would reduce potential long-term water quality impacts to a level considered less than significant. LonQ-Term Qoerational Water Qualitv Imoacts The quality of the water runoff from the project site would be improved as compared to existing conditions. Currently, all surface runoff sheet flows from the site onto Foothill Boulevard and R:\Projects\TuslinIJOO3\IS-122005.doc 5.19 Environmental Evaluation Resolution No. 06-49 Page 53 of 171 Rawlings Reservoir Replacement Project Initial Study gravity flows to a catch basin in Hewes Avenue. There is currently no treatment of the water prior to its discharge to the public storm drain system. However, the amount of surface runoff would not substantially increase as a result of project implementation. Surface water from the project site would be captured in on-site storm drain facilities and conveyed to new storm drain pipes which would discharge to an existing storm drain pipeline as shown in Exhibit 8. Construction of the project would require an amendment to the City's Water Supply Permit Number 04-89-001 issued by the California Department of Health Services. The proposed project would not result in violations of any water quality standards or substantially degrade water quality. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? No Impact. Free groundwater was not encountered during geotechnical borings drilled to a maximum depth of 41 feet. Seepage was encountered in hand-auger borings at depths ranging from 2.5 to 6 feet. However, since the Puente formation underlying the site is primarily impermeable, it is expected that the seepage was from perched groundwater and this may also be encountered during grading, particularly at the fill/bedrock contact, and trapped immediately under the existing reservoir. The amount of permeable surface on site is very small and would not change substanti ally with project implementation. The proposed project would not cause any long-term interference with groundwater recharge or affect existing aquifer volumes, and would not involve the depletion of groundwater supplies. No impacts would occur. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? No Impact. Stormwater runoff from the project site currently sheetfiows to the south and then drains to Foothill Boulevard and ultimately to existing stormdrains. The project site is not in close proximity to a stream or river, nor would runoff from the site enter a stream or river and alter its course. Implementation of the proposed project would slightly increase the amount of impervious surface on-site; however, this increase would not result in substantial increase in the rate or amount of runoff from the site that would cause an increase in erosion or flooding. Additionally, the proposed project involves the construction of new stormdrains to capture site runoff which would reduce the amount of erosion that currently occurs with the sheetfiow condition. No significant impacts would occur. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? Less Than Significant Impact. The amount of surface runoff would not substantially increase as a result of project implementation since the on-site uses would be similar to existing conditions and only a small amount of additional impervious surface would be added. Additionally, runoff from the project site already drains to the existing storm-drain facility in R:\Projecls\T ustinIJOO3\lS-122005.ooc Resolution No. 06-49 Page 54 of 171 5-20 Environmental Evaluation Rawlings ReseiVoir Repfacement Project Initial Study Hewes Street via gutters in Foothill Boulevard. As part of the proposed project, a new storm drain line would be installed in Foothill Boulevard to convey water to an existing OCFCD facility. As discussed in Section 3.2.3, Off-site Project Features, two options are under consideration for storm-drain line connections. The OCFCD facility along Newport Avenue has sufficient capacity to accommodate the drainage from the project site. There would be a negligible increase in the amount of water entering the facility in Hewes Street as this is where the site runoff currently flows. The proposed project would not involve the construction of any uses that would alter the type or amount of pollutants in the runoff from the project site. Less than significant impacts relative to stormwater runoff would result from the project. g) Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? h) Place within a 100-year flood hazard area structures which would impede or redirect flood flows? No Impact. According to the Federal Emergency Management Agency (FEMA), the project site is not located in a special flood hazard area (100-year or less floodplain). Additionally, the proposed project does not include the development of new housing. Therefore, the proposed project would have no im pacts associated with flood hazards to housing or other structures. i) Expose people or structures to a significant risk of loss, injury or death involving flooding as a result of the failure of a levee or dam? Less Than Significant Impact. Although the proposed project is not in proximity to any existing levee or dam, it would involve the construction of two new 3.0 MG concrete water storage tanks. The hoop reinforcing in the sidewall and the tendons from the base to the sidewall allow the reservoir to flex, if necessary, without failing. The proposed project would be designed and constructed in accordance with the American Water Works Association (AWWA) Standard D110-95, American Concrete Institute (ACI) Standard 350, and the most current version of the Uniform Building Code. This would safeguard against major structural failures. Adherence to these standards would reduce potential impacts associated with new construction to a less than significant level. j) Inundation by seiche, tsunami, or mudflow? No Impact. A seiche is an oscillation of a landlocked body of water that can cause water damage to buildings, roads, and infrastructure that surround the body of water. There is no sllch body of water located in the City of Tustin. Therefore, impacts to the project study area associated with seiches would not occur. Additionally, the project site is approximately 9.6 miles from the Pacific Ocean or any body of water that could cause tsunami, also know as tidal waves, to the area. There is no risk of tsunami associated with the project. By definition, mudflows are considered a type of landsl ide and the site is not located in an earthquake- induced landslide seismic hazard zone according to the April 15, 1998, Seismic Hazard Zones Map for the Orange Quadrangle. No impacts are expected. k) Potentially impact stormwater runoff from construction activities? Less Than Significant. Refer to Checklist Item VlIl.a which discusses the regulatory setting for water quality. The proposed project could result in short-term construction impacts to surface water quality from grading and other construction-related activities. Construction activities WOJld result in the disturbance of soils on the project site and would result in increased erosion. Storm R:\ProjectsITustinUOO3\1S-122005.doc 5-21 Environmental Evaluation Resolution No. 06-49 Page 55 of 171 Rawlings Reservoir Replacement Project Initial Study water runoff from the project site during construction could contain soils and sediments from these activities. Spills or leaks from heavy equipment and machinery: construction staging areas, which typically include petroleum products such as fuel, oil and grease; and heavy metals can also enter runoff. Compliance with the NPDES Construction General Permit and the preparation and implementation of a SWPPP would ensure that any impacts to down stream waters resulting from construction activities associated with the project site would be less than significant. Erosion control and treatment BMPs would be implemented per NPDES requirements. In addition to the requirements of the NPDES General Construction Permit, provisions of the Uniform Building Code and grading permit requirements include elements that also require reduction of erosion and sedimentation impacts during construction. Full compliance with applicable local, state, and federal regulations would reduce water quality impacts associated with construction to a less than significant level. I) Potentially impact stormwater runoff from post-construction activities? Less Than Significant Impact. Refer to the discussion under Checklist Items VlIl.a. and VlIl.e. m) Result in a potential for discharge of stormwater pollutants from areas of material storage, vehicle or equipment fueling, vehicle or equipment maintenance (including washing), waste handling, hazardous materials handling or storage, delivery areas, loading docks or other outdoor work areas? No Impact. As with existing conditions, the project does not include areas of material storage, vehicle or equipment fueling; vehicle or equipment maintenance; waste handling; hazardous materials handling or storage: delivery areas; loading docks; or other outdoor work areas. Therefore, the proposed project would not result in a potential for discharge of storm water pollutants as a result of these uses. n) Result in a potential for discharge of stormwater to affect the beneficial uses of the receiving waters? No Impact. As discussed above, the amount and quality of surface runoff from the project site would not substantially change compared to existing conditions. The proposed would not involve any activities that would result in impacts to the quality of the stormwater runoff. Therefore, the proposed project would not affect the beneficial uses of the receiving waters. 0) Create the potential for significant changes in the flow velocity or volume of stormwater runoff to cause environmental harm? No Impact. The amount of surface runoff would not substantially increase as a result of project implementation. There would be no significant change to existing stormwater flow velocity or volume as a result of the project. No impacts would result. p) Create significant increases in erosion of the project site or surrounding areas? No Impact. Refer to the discussion for Checklist Item VlIl.c. As noted, the proposed project would not result in a significant increase in erosion.

Pursuant to the permit requirements. the contractor shall develop an SWPPP that incorporates BMPs for reducing or eliminating construction-related pollutants in the site runoff. SC8-2 Prior to approval of grading plans, the contractor shall submit a project water quality management plan (WQMP) to the Public Works Department for review and approval. The WQMP shall demonstrate compliance with the implementation plans under the MS4 Permit, namely the Drainage Area Management Plan (DAMP). Sources . Federal Emergency Management Agency Q3 Flood Data, Orange County, 1996. IX. LAND USE AND PLANNING Would the project; a) Physically divide an established community? No impact. The project site is bounded by Foothill Boulevard and Foothill High School to the south, an unnamed private road and single family residences to the east, an undeveloped slope and a single family residence to the west, and a single family residence to the north. The existing reservoir was constructed in 1971, and there is also a booster pump station on site. The use of the site for water storage purposes would remain the same with the proposed project and would not physically divide an established com munity. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? No Impact. With the exception of a sliver of property along Foothill Boulevard within unincorporated Orange County, the property is an incorporated island in the City of Tustin surrounded by unincorporated area within Orange County, and has General Plan Land Use Designations of Low Density Residential and Public/Institutional. The proposed project would be designated as Public/Institutional use and therefore would not conflict with the Tustin General Plan, zoning ordinance, other policies, or regulations applicable to the area. c) Conflict with any applicable habitat conservation plan or natural community conservation plan? No Impact. Refer to the discussion under Checklist Item IV.f (Section IV, Biological Resources). As noted, the project site is within the County of Orange Central and Coastal NCCP/HCP. However, it would not conflict with the implementation of this program. The project site is within a development area. RIProjects\Tustin\JOO3\IS-122005.doc 5-23 Environmental Evaluation Resolution No. 06-49 Page 57 of 171 Rawlings Reservoir Replacement Project Initial Study Mitigation Program No significant impacts have been identified and no mitigation is required. Sources . City of Tustin General Plan. Land Use Element, January 16, 2001. X. MINERAL RESOURCES Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? No Impact. The California Division of Mines and Geology (CDMG) is the state agency with the responsibility to oversee the management of mineral resources in California. The CDMG considers a site to be significant with regard to mineral commodities if the site can be mined commercially and there is enough of the resource to be economically viable. There are no such resources on-site. The Tustin General Plan does not identify any mineral resources in the City. Therefore. the proposed project would not result in the loss of availability of a known mineral resource. b) Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? No Impact. The Tustin General Plan does not identify any mineral resources in the City. Therefore, the proposed project would not result in the loss of availability of a known mineral resource. Mitigation Program No significant impacts have been identifi ed and no mitigation is required. Sources . City of Tustin General Plan, Conservation/Open Space/Recreation Element, January 16, 2001. XI. NOISE Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant. The maximum allowable noise level for residential districts in Tustin is 55 dB from 7:00 a.m. to 10:00 p.m. and 50 dB from 10:00 p.m. to 7:00 a.m. Exceptions are made for noise sources associated with construction activities between the hours of 7:00 a.m. R:\Pro~ects\Tustjn\JOO3\IS-122005,doc Resoiulion No. 06-49 Page 58 of 171 5-24 Environmental Evaluation Rawlings Reservoir Replacement Project Initial Study and 6:00 p.m. Monday through Friday, and between the hours of 9:00 a.m. and 5:00 p.m. on Saturdays, excluding City-observed federal holidays. Construction noise represents a short-term impact on ambient noise levels. Noise generated by construction equipment, including trucks, graders, bulldozers, concrete mixers and portable generators, can reach high levels. The greatest construction noise levels are typically generated by heavy grading equipment. As noted in Section 3, Project Description, site excavation and grading activities would last only two months. Exhibit 9 depicts typical noise levels generated by construction equipment. Pile driving would not be required for the proposed project. Construction noise levels generated by commonly-used grading equipment (i.e. loaders, graders, and trucks) generate noise levels that typically do not exceed the middle of the ranges shown on Exhibit 9. For the purposes of this analysis, an overall grading noise level of 89 dBA at 50 feet is used as the worst-case maximum exterior noise level. Using a drop-off rate of 6 dBA per doubling of distance, noise levels at 100 feet and 200 feet are estimated at 83 dBA and 77 dBA, respectively. The nearest homes are located across the private access road, approximately 30 feet to the east. Construction of the project would result in noise levels at surrounding residential areas in excess of the limits presented in the City of Tustin Noise Ordinance. However, the City's Noise Ordinance excludes noise control generated by construction activities during specific time periods, as stated previously. In accordance with this ordinance, construction of the project would not occur outside of these hours nor on Sundays or City-observed federal holidays. Therefore, noise generated by the construction of the project would comply with the City's Noise Ordinance and construction of the project would not result in a significant noise impact. It should be noted that although a significant noise impact would not result from construction of the project due to the temporary nature of the activity and the time constraints of the City's Noise Ordinance, the City retained Mestre-Greve Associates (MGA) to evaluate methods to further reduce construction noise levels. MGA's recommendations are listed as special conditions (Noise-1 through Noise-3) and are provided below. The special conditions would be incorporated into the project during construction. b) Exposure of persons to or generation of excessive ground borne vibration or groundborne noise levels? No Impact. The proposed project would involve typical construction activities and equipment. There would be no construction or operational activities that would generate excessive groundbourne vi brations or noise. No impacts would result. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels exist ing without the project? No Impact. Operations at the project site for the new water reservoirs would be similar to existing conditions. The existing booster pump station would remain. The proposed project would not generate operational noise above existing noise levels and no impacts would occur. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The project is not located within an airport land use plan or within two miles of an airport.

Memorandum from F. Greve, Mestre-Greve Associates to T. Andersen, BonTerra Consulting, dated November 23,2005. XII. POPULATION AND HOUSING Would the project: a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? No Impact. The purpose of the proposed project is to provide improved water storage capacity for existing customers, and to replace an aging reservoir that has structural deficiencies. The R\Projects\Tustln\JOO3\1S-122005.doc 5-26 Environmental Evaluation Resolution No. 06-49 Page 61 of 171 Rawlings Reservoir Replacement Project Initial Study proposed project does not have the potential to induce population growth in the area. No impacts would result. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. There is no housing on the project site and implementation of the project would not displace any existing housing people. No impacts to population or housing would occur. XIII. PUBLIC SERVICES a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Fire protection? Police protection? Schools? Parks? Other public facilities? No Impact. Construction of two water tanks and underground storm drains would not create significant additional demand for, or alteration of. government facilities or services (fire and police protection, schools. parks. etc.). The project would facilitate the provision of water and fire protection in the water service area by improving City water facilities. The proposed project would not result in an increase in the City's population and the site would be used for the purposes as existing conditions. Therefore. there would be no impacts to police services, schools. or parks and no need for new facilities that could cause environmental impacts. No impacts would occur. It should also be noted that the City's Capital Improvement Project fund includes funding resources for the proposed project and the City's Water Division Operating Budget includes funding for the operation and maintenance of the facility. Mitigation Program No significant impacts have been identifi ed and no mitigation is required. XIV. RECREATION a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? No Impact. The proposed project would not increase population and housing in the area. and the demand for recreational facilities would not increase since the site would be used for the same purpose as it is currently. Therefore, there would not be an increased demand for R:\Pmjepts\Tu~lin\JOO.1l~-1?~OO5.doC Resolution NO. Ub-411 Page 62 of 171 5-27 Environmental Evaluation Rawlings Reservoir Replacement Project Initial Study recreational facilities and no physical deterioration of existing recreational facilities in the area would occur. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? No Impact. The project site is not located in or adjacent to a City or County recreational facility and would not require the construction or expansion of recreational facilities on-site or off-site. Therefore, implementation of the project would not have a physical environmental impact relating to recreational facilities. Mitigation Program No significant impacts have been identifi ed and no mitigation is required. Sources . City of Tustin General Plan, Conservation/Open Space/Recreation Element, January 16, 2001. XV. TRANSPORTATION/TRAFFIC Would the project; a) Cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system (i.e. result in a substantial Increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? Less Than Significant Impact. The proposed project would not increase vehicle trips or traffic congestion beyond adopted policies and/or forecasts. Once the project is constructed, the only trips associated with the facility would be trips by City employees for maintenance and inspection consistent with existing conditions. There would be a short-term increase in traffic generated during the construction period. Vehicle trips would be associated with trucks hauling materials and supplies to the site and workers commuting to and from the site (refer to the project description provided in Section 3). There would be an average of 17 daily trips. The additional trips would be temporary in nature and would not cause any impacts to existing roadway operating conditions. No short-term or long-term significant traffic impacts would result from the project. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? No Impact. The increase in traffic to the project site during construction would be negligible and short-term. After construction, the proposed project would not generate traffic above existing conditions. Therefore, the proposed project would not exceed any level of service standards. The Orange County Master Plan of Arterial Highways (MPAH), which is maintained by the Orange County Transportation Authority (OCTAl and forms the basis of Orange County's Congestion Management Program (CMP), designates Newport Avenue as a primary arterial. By definition, a primary arterial is a four lane divided roadway designed to accommodate between 20,000 and 30,000 average daily trips (ADT). However, there are no roadways identified in the CMP that are adjacent to the project site, and the trips generated by the project would be R:\Projects\Tuslln\JOO3\1S-122005.doc 5-28 Environmental Evaluation Resolution No. 06-49 Page 63 of 171 Rawlings Reservoir Replacement Project Initial Study "immeasurable" as they only relate to an occasional trip made for maintenance purposes. No impacts would occur. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? No Impact. The proposed project is not near any airports and would have no impact on air traffic patterns. d) Substantially increase hazards due to a design feature (e.g. sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact. The project site would be used for the same purpose as existing conditions and the proposed project would not increase hazards. It should be noted that the access into the site from Foothill Boulevard would be improved with a new access point to the west of the booster pump station. e) Result in inadequate emergency access? Less Than Significant Impact. During construction activities, the existing private street east of the project site would be closed temporarily. This street serves residences to the north of the project site; however, a secondary access is also available from the north ensuring continuous emergency access. Following construction of the proposed project, current emergency access and evacuation conditions would be the same. No significant impacts to emergency access would result. f) Result in inadequate parking capacity? No Impact. The proposed project would not involve an increased demand for parking or the removal of existing parking. No impacts would result. g) Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? No Impact. The proposed reservoir replacement project does not require the incorporation of alternative transportation facilities and would not conflict with any alternative transportation policies, plans, or programs. The proposed project would improve the north side of Foothill Boulevard including the provision of a sidewal k. No impacts would result. Mitigation Program No standard conditions and regulations are applicable and no mitigation is required. Sources . City of Tustin General Plan, Circulation Element, January 16, 2001. .

UTILITIES AND SERVICE SYSTEMS Would the project: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? No Impact. Implementation of the proposed project would not generate wastewater. Therefore, no wastewater treatment requirements would be exceeded. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. The proposed project involves replacement of an existing water reservoir to increase the City's water storage/supply capacity. The potential environmental impacts associated with implementation of the project have been evaluated throughout this Initial Study. With implementation of the standard conditions and mitigation measures identified, no significant impacts would result. The proposed project would not generate wastewater and no new wastewater facilities would be required. c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Less Than Significant With Mitigation. The proposed project would involve construction of a new storm drain line from the project site, within Foothill Boulevard to an existing OCFCD along Hewes Street or Newport Avenue. Each of these off-site storm drain connection options would require installation of a new storm drain in Foothill Boulevard. This construction would occur within the existing street right-of-way and would result in short-term, construction-related impacts, including traffic disruption. This impact would be mitigated to a level considered less than significant with implementation of traffic management plans. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? No Impact. The proposed project would improve the City's water supply system. No water supply is necessary to serve the project because the project would not involve the increase of population or consumption of water. e) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? No Impact. As with existing conditions, the proposed reservoirs would not generate wastewater and would not dem and any wastewater treatment capacity. R:\ProjectsITustlnIJOO3\1S-122005.doc 5-30 Environmental Evaluation Resolution No. 06-49 Page 65 of 171 Rawlings ReseNoir Replacement Project Initial Study f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? g) Comply with federal, state, and local statutes and regulations related to solid waste? Less Than Significant Impact. Demolition of the existing reservoir, site preparation (vegetation removal and grading activities), and construction activities would generate typical construction debris, including wood, paper, glass, plastic, metals, cardboard, and green wastes. Solid waste generated from the proposed project site would most likely be disposed at the Frank R. Bowerman Landfill (closest landfill to the site) which is part of the Orange County landfill system operated by the County's Integrated Waste Management Department (IWMD). This landfill has a projected closure date of 2022 with a remaining disposal capacity of 75.5 million cubic yard (cy) as of June 20, 2005. The construction-related solid waste generated by the project would be negligible, and could be accommodated within the permitted capacity of the County's landfill system. Similar to existing conditions, operation of the new reservoirs would not generate solid waste. No significant impacts would occur and no mitigation is required. h) Would the project Include a new or retrofitted storm water treatment control Best Management Practice (BMP), (e.g. water quality treatment basin, constructed treatment wetlands), the operation of which could result in significant environmental effects (e.g. increased vectors and odors)? No Impact. The proposed project would involve the construction of a new storm drain line that would connect to an existing structural OCFCD facility. The proposed project does not involve the implementation of any new or retrofitted storm water treatment control BMPs. Therefore, no environmental impacts would result. Mitigation Program Mitiqation Measures MM 16-1 Prior to approval of street improvement plans, the contractor shall submit Traffic Management Plans to the County of Orange for review and approval. The Traffic Management Plans shall describe traffic control measures that shall be implemented to maintain traffic flow in all directions where utility improvements are being implemented in existing roadways. Said traffic management measures shall be implemented on-going during road construction. XVII. MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Less Than Significant Impact. The project proposes the replacement of an existing reservoir on the same site. There are no sensitive biological resources, habitat, or species located on the project site that would be affected by the proposed project. Additionally, the proposed project would not impact any archaeological or historical resources as construction activities would occur in previously disturbed areas and no historical resources are located on-site. R:\ProjecIsITustinIJOO3\I$-122005.doc Resolution No. 06-49 Page 66 of 171 5-31 Environmental Evaluation Rawlings Reservoir Replacement Project Initial Study b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects). Less Than Significant Impact. The potential environmental impacts resulting from implementation of the proposed project have been evaluated in this Initial Study and have been determined to be less than significant or mitigated to a level considered less than significant. The project involves the replacement of an existing water reservoir with two new reservoirs on the same site. The project site is already developed and is located in an urbanized area. The proposed project would not result in impacts that are cumulatively considerable. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Less Than Significant Impact. The proposed water reservoir replacement project would not alter the use or operation of the project site compared to existing conditions and would not result in substantial adverse effects on human bei ngs.

In summary, the proposed project involves the demolition of an existing water reservoir and the construction and operation of two new reservoirs. Pursuant to Public Resources Code Section 21 080( c)(2), the City of Tustin determined that a Mitigated Negative Declaration (MND) was the appropriate environmental document for the project. Public Resources Code Section 21091(f) and the CEQA Guidelines Section 15074 require that the lead agency must consider the MND before approving the project. Specifically, Section 15074(b) states: "Prior to approving a project, the decisionmaking body of the lead agency shall consider the proposed negative declaration or mitigated negative declaration together with any comments received during the public review process. The decision making body shall adopt the proposed negative declaration or mitigated negative declaration only if it finds on the basis of the whole record before it (including the initial study and any comments received), that there is no substantial evidence that the project would have a significant effect on the environment and that the negative declaration or mitigated negative declaration reflects the lead agency's independent judgment and analysis.' Following is a list of the public agencies, organizations, and individuals that submitted comments on the IS/MND: STATE AGENCIES 1. California Governor's Office of Planning and Research (February 2, 2006) 2. Department of Toxic Substances Control (January 27, 2006) 3.

Per CEQA, the lead agency is not required to prepare formal responses to comments received on the IS/MND; however, the City of Tustin has elected to prepare written responses to comments. Each comment letter received is included in Section 2 of this document and is immediately followed by the City's response. Responses to comments made at the January 12, 2006, community meeting are also provided. 1.2 PUBLIC NOTIFICATION AND REVIEW PROCESS Section 15072 of the State CEQA Guidelines states: "(alA lead agency shall provide a notice of intent to adopt a negative declaration or mitigated negative declaration to the public, responsible agencies, trustee agencies, and the county clerk of each county within which the proposed project is located, sufficiently prior to adoption by the lead agency of the negative declaration or mitigated negative declaration to allow the public and agencies the review period provided under Section 15105. (b) The lead agency shall mail a notice of intent to adopt a negative declaration or mitigated negative declaration to the last known name and address of all organizations and individuals who have previously requested such notice in writing and shall also give notice of intent to adopt a negative declaration or mitigated negative declaration by at least one of the following procedures to allow the public the review period provided under Section 15105: (1) Publication at least one time by the lead agency in a newspaper of general circulation in the area affected by the proposed project. If more than one area is affected, the notice shall be published in the newspaper of largest circulation from among the newspapers of general circulation in those areas. (2) Posting of notice by the lead agency on and off site in the area where the project is to be located. (3) Direct mailing to the owners and occupants of contiguous property shown on the latest equalized assessment roll." The City of Tustin complied with the requirements to notify agencies and interested individuals about its intent to adopt an MND for the Rawlings Reservoir Replacement Project. The notice of intent was distributed on December 22, 2005, to various agencies, organizations, and individuals including the County of Orange Clerk/Recorder and property owners within 300 feet of the project s~e. The notice was also published in the Tustin News on December 22, 2005, informing all City customers and residents of the greater Tustin area of the availability of the MND, and the Notice of Intent to adopt an MND was posted on the project site. Although not required, on December 20, 21, and 22, 2005, City staff contacted residents within a 300-foot radius of the project by telephone to inform them of the proposed project. Additionally, a letter was sent to these residents on January 4, 2006, to further infonn them of the proposed project and the scheduled infonnational community meeting. A copy of the MND was requested by and distributed to several area residents. The City of Tustin held an informational community meeting on January 12, 2006, at Foothill High School regarding the project. The meeting was attended by approximately 13 individuals.

Additionally, the contaminants should be remediated in compliance with California environmental regulations and policies. 8) The project construction may require soil excavation and soil filling in certain areas. Appropriate sampling is required prior to disposal of the excavated soil. If the soil is contaminated, property dispose of it rather than placing it in another location. Land Disposal Restrictions may be applicable to these soils. Also, if 8 the project proposes to import soil to backfill the areas excavated, proper sampling should be conducted to make sure thatlhe imported soil is free of contamination. 9) Human health and the environment of sensitive receptors should be protected during the construction or demolition activities.

The existing environmental setting of the project site is described in Section 2.1 of the IS/MND. As noted in Section 2.2, Project Background, the project site has been developed with a water reservoir and associated facilities since 1971. Prior to the construction of the current reservoir, the site was developed with a private residence. These uses have not resulted in the release of hazardous waste/substances. 2. Based on a records search conducted by Environmental Data Resources Inc. (EDR), dated February 3, 2006, and as reported by The EDR Radius Map with GeoCheck, the project site is identified on the HAZNET database for asbestos-containing waste. However, despite the presence of asbestos containing material (ACM), no actual release of ACM has ever occurred at the site and no remedial action has ever been required. The potential impact from the presence of asbestos-containing materials on site is analyzed in Section 5.VII of the IS/MND, Hazards and Hazardous Materials and is based on a comprehensive Asbestos and Lead Survey that was conducted at the site. While the existing reservoir does have asbestos-containing materials, consistent with information reported in the EDR report, the removal, transportation and disposal of ACM during construction would be conducted in strict compliance with applicable federal, state and local regulations including, but not limited to, South Coast Air Quality Management District (SCAQMD) Rule 1403. In addition, the contractor would be required to submit an Asbestos Management Program to the City's Department of Public Works prior to issuance of any grading permit in accordance with Mitigation Measure (MM) 7-1. 3. As discussed in Section 5.VII of the IS/MND, Hazardous and Hazardous Materials, the only hazardous materials known to occur on site is asbestos-containing materials. In order to ensure continued protection of human health and the environment of sensitive receptors, all project-related demolition activities shall comply with Southern California Air Quamy Management District (SCAQMD) Rule 1403-Asbestos Emissions From Demolition/Renovation Activities. In addition to compliance with Rule 1403, the Asbestos Abatement Contractor shall comply with applicable regulations set forth by the Environmental Protection Agency, the Occupational Safety & Health Administration, and the Department of Health Services. 4. MM 7-1 (page 5-18 of the IS/MND) requires the preparation of an Asbestos Management Program prior to the issuance of a demolition permit for the existing reservoir structures. There are no other hazardous substances on site that require investigation, sampling and/or remediation. 5. The removal of asbestos-containing material on site would be completed prior to construction or the new reservoirs and would be conducted in accordance with requirements of the Asbestos Management Program prepared for the project site. Also refer to response to comment 3 above. 6. Based information presented in The EDR Radius Map with GeoCheck, no contaminated sites or sites that qualify as "Border Zone Properties" were identified within 2,000 feet of the project site. R"\Pro/llC1s1TuSllnUOO3\RTC-Q40006_doc 2-3 ~~~1~fi~ncm~'5'lf-49 Page 109 of 171 Rawlings ReselYoir Replacement Project Responses to Comments 7. As noted in Section 5VII of the IS/MND, an asbestos and lead survey was conducted for the proposed project in compliance with all regulatory agency requirements, including SCAQMD Rule 1403, and included all structures and facilities to be demolished. Asbestos- containing materials were the only hazardous materials located on site. There was no presence of materials with lead levels at or above the United States Department of Housing and Urban Development (HUD) Guidelines. No other hazardous materials or chemicals were detected. 8. Prior to development of the site with the existing water reservoir, the project site was developed with a residential use. Based on review of historic photographs, and the information provided in the EDR records search, it is not anticipated that the on-site soils have been contaminated. However, the on-site soils would be sampled prior to disposal. Should contaminated soils be encountered they would be disposed of properly. Soils used for backfill after the new reservoirs are constructed would also be sampled; contaminated soils would not be used. 9. Based on investigation of the project site, review of applicable records for hazardous materials, and historic use of the site as a private residence, there is no evidence that the project site has been subject to improper handling or release of chemicals or other hazardous materials. The IS/MNO identifies that asbestos-containing materials are located on site and notes that these materials can become friable if damaged or disturbed. Removal of these materials would be conducted in accordance with Standard Condition (SC) 7.1 and MM 7-1 to reduce potential impacts to a level considered less than significant. 10. As identified in Section 5.VII, item (c) of the ISIMND (page 5-17), the proposed water reservoir replacement project does not include the construction of any uses that would involve the use, storage, or transport of hazardous materials resulting in the risk of release or emission of hazardous materials. 11. As identified in Section 5VIII, Hydrology and Water Quality, item (f) (page 5-19), the State Water Resources Control Board (SWRCB) has issued a statewide, general National Pollutant Discharge Elimination System (NPDES) permit (NPOES No. CAS000002) for stormwater discharges from construction sites with a disturbance area of one or more acres, including the project site. This general permit requires that individual construction sites obtain individual NPDES permits for stormwater discharges or be covered by the Construction General Permit. Per SC 8-1, a Notice of Intent to obtain coverage under the Construction General Permit would be filed for the project. Long-term operation of the proposed water reservoir would not involve any discharge of wastewater into the stormdrain system. 12. Based on investigation of the project site and review of applicable records, there is no evidence of soil and/or groundwater contamination on site. However, should such contamination be suspected, demolition and construction activities would cease and health and safety measures would be implemented in compliance with applicable local, state, and federal requirements.

The comment acknowledges receipt and review of the IS/MND and requests written responses to the comments contained within the letter. Written responses are provided below. 2. SC 7-1 (page 5-18) of the IS/MND acknowledges that compliance with SCAQMD Rule 1403 (Asbestos Emissions From Demolition/Renovation Activities) is required. Asbestos removal work would be conducted in an isolated work area. Additionally, engineering controls would be implemented which may include, but not be limited to: the use of High Efficiency Particulate Air (HEPA) filtration systems which would operate continuously from the commencement of work until the final clearance is achieved; wet removal methods; HEPA vacuums; and perimeter air sampling with on- and off-site analysis. Additionally, although not required, asbestos removal would be monitored by an independent environmental consulting firm retained by the City to ensure compliance with the regulations set forth in SCAQMD Rule 1403. Should any form of non- compliance be observed, the independent consultant would immediately notify the City and the City would order the contractor to cease all ACM removal activity until the non- compliance issue is resolved to the satisfaction of the City. 3. The air quality analysis conducted for the proposed project was completed in accordance with current SCAQMD analysis requirements as specified in SCAQMD's CEQA Handbook. SCAQMD has not mandated that local agencies conduct localized air quality analyses for all development projects (see AQMD Fact Sheet, "Localized Significance Thresholds" [LSTS]). The only required analysis is the analysis set forth in the CEQA Handbook, which is the analysis that has properly been conducted for this project. The purpose behind SCAQMD's development of LSTs was merely to provide lead agencies with a tool for assessing the localized air quality impacts of the project should an agency decide to conduct such an analysis. (lQ., p.2). In this case, the City elected not to conduct a localized air quality analysis because the project site is not located within an area that is currently plagued by disproportionately higher levels of air pollution, such as, for example, industrial areas or transit corridors. The general area is primarily residential. Consistent with the methodology for analyzing construction emissions established in the SCAQMD handbook and as presented in Section 5.111 of the IS/MND, with mitigation, the proposed project would not exceed any of the SCAQMD's significance thresholds. It is important to note that pollutant emissions would only occur temporarily during construction. These emissions would cease upon project completion. It should be noted that the IS/MND did identify PM" emissions to be significant prior to mitigation. The air quality mitigation measure included in the IS/MND (MM 3-1) indicates that the contract specifications shall require compliance with all applicable SCAQMD Rules and Regulations including Rule 403 to reduce the proposed project's potential PM10 impacts. Specific measures which will be required of the contractor are listed in the IS/MND. As a result, construction of the proposed project will not exceed SCAQMD's significance threshold for PM,0. On the contrary, PM" emissions will be well below SCAQMD's daily significance threshold (refer to Table 3 on page 5-7 of the IS/MND). R'\Proj$Cl1lITusUn\JOO3\RTC-040600.doc 2-6 Responses to Comments Resolution No. 06-49 Page 115 of 171 Rawlings Reservoir Replacement Project Responses to Comments With respect to CO and NOx emissions, the air quality analysis performed for the proposed project indicates that construction of the proposed project would not result in an exceedance of SCAQMD's thresholds for these criteria pollutants (refer to Tables 2, 3, and 4 in the IS/MND). However, in a good faith effort to minimize potential construction-related air quality impacts to the greatest extent feasible, the City hereby incorporates the following mitigation measures in the IS/MND. This mitigation measure does not change the conclusions of the IS/MND as presented. MM 3-2 Prior to issuance of a grading permit, the Community Development Department shall verify that the following requirements are included on the contractor specifications: . all equipment shall be properly tuned and maintained in accordance with the manufacturers' specifications . engines on trucks and vehicles in loading and unloading queues shall be turned off when not in use to reduce vehicle emissions . construction activity shall utilize electricity from power poles rather than temporary diesel or gasoline power generators, to the extent feasible . all on-site mobile equipment used during construction shall be powered by alternative fuel sources, where feasible . all on-site heavy-duty construction equipment shall be equipped with diesel particulate traps to the extent that this equipments is available at the time the contracts are awarded . emulsified diesel fuel shall be used in diesel-fueled construction equipment that is not equipped with diesel particulate traps to reduce NOx emissions. It should also be noted that on-site construction activities would be monitored on a daily basis by City staff. This would include visual monitoring to ensure that dust emissions are not dispersing to adjacent properties. Additionally, the City would implement a publiC outreach program for the project to maintain communication between the community and the City during construction phases. This will include provision of a "call-in" number to report any concems during implementation of the project. 2-7 Responses to Comments R,\Projects\TustInUOO3\RTC-040606 doe Resolution No. 06-49 Page 116 of 171 Comment Letter 5 ~ ~ ' .. ~ J ~ City of Tustin Scott Reekstin 300 Centennial Wy Tustin, CA 92780 ORANGE COUNTY FIRE AUTHORITY P.O.

I Initially heard about It through word-of-mouth. My five main concerns for this project are as follows: P-'lllJ-'-'~UOIl' The team talked about contacting the property owners within 500' of the project site, According to my caleulations that's approximately 33 homes, In speaking with many of my neighbors this weekend, It appears that the majority have NOT been contacted. Some received a letter from the City of Tustin along with the Initial Study and others received just a letter. I do think an Initial effort was put forth by the City of Tustin but It wasn't complete (even though $75K was budgeted for public outreach). ALL of the property owners within 500' should have received the same information at the same time, Why were some given the study and others not even notified (Including myseif)? 1 30"PQ: Bu.!.w .C;~mmflntPedll.c1 I am perplexed why the 3D-day public comment period was launched on December 22nd, This period Is typically the busiest time of year for most people, Plus, there are several major holidays during this 30-day window In which the City of Tustin offices are closed. That means roughly 18 business days are available for the public to contact the city directly which Is not much ttme before the January 20th cut-off date for questions, We were told at the meeting that questions would be taken after January 20th and If that Is the case, then why impose a cut-off date altogether? 2 (;~UJlty .of OrInllLLaml.UleAaRtOYMI We learned that the RaWlings Reservoir sits on land owned by the City of Tustin, like an island, with the surrounding land managed by the County of Orange. That still means, however, that approvals must be obtained by the County of Orange Planning Department AND the North Tustin Advisory Committee (NTAC). At the meeting I asked if NTAC had been contacted and the response was: 'Our mailing was sent back to us as the NTAC address was Incorrect". That Is not a Justifiable reason to bypass NTAC's board for approval of the project -- It simply means that someone must make more of an effort to get the right information (the County of Orange Planning Dept, has the right address if necessary). 3 ~U!.ll.mOYII.PJlln I asked the team what the plan Is for removing the asbestos materials at the project site. The response was that all of the asbestos would be handled In accordance to the AQMD's }4 01/24/2006 Resolution No. 06-49 Page 119 of 171 Page 2 of2 requirements, Nice to hear but I asked "when" the plan would be ready for review, They told us "at a later date" which seemed very vague considering the importance of this Issue, I subsequently learned In re-readlng the Initial Study (atter the meeting) that the selected contractor "shall submit an Asbestos Management Program (AMP) to the Public Works Department". That tells me the plan will be developed AFTER the project Is approved by the Tustin City Council, 4 cont. Given that this project site is In close proximity to three schools (Foothill, Hlllview and Hewes) roughly 4,000 people could be greatly effected, While It might be "standard operating procedure" to develop the plan later on, it would be far better for the community to know the details now, Personally, I can't offer my support for the project without all of the details and this is the most Important of all. LlII1d.QJle.J>JilO } A cosmetic concern and far less important than the previous point. Regardless, the City of Tustin should present the landscape plan to the public so that we have something to comment on during the 3D-day review period. Yes, I understand that this is "not required" at this pOint in the project 5 but It makes solid sense to have the details now. From my viewpoint, this project Is moving too quickly and the publiC has not had enough time to } (a) be notified, and (b) be presented with ALL of the necessary facts, lam requesting the City of Tustin extend the review/comment period until after the asbestos removal ancllanclscaplng plans 6 have been presented in a public forum. During this time, approvals must be obtained by the County Planning Department and NTAC as mentioned above. I welcome the opportunity to discuss these points with you in further detail, Please feel free to contact me at your earliest convenience. Best, Mike Fioravanti 19331 Gateway Drive North Tustin 714,544,7207 01/24/2006 Resolution No. 06-49 - Page 120 of 171 Rawlings Reservoir Replacement Project Responses to Comments Comment Letter 6 Mike Fioravanti January 16, 2006 1, Please refer to Section 1.2 for a discussion of the public notification and review process for the Initial Study and notice of intent to adopt an MND that was conducted by the City of Tustin. Residents within 300 feet of the project site were mailed notifications and adjacent property owners were provided with a copy of the IS/MND. 2. Per CEQA Guidelines Section 15073(a), "the lead agency shall provide a public review period pursuant to Section 15105 of not less than 20 days. When a proposed negative declaration or mitigated negative declaration and initial study are submitted to the State Clearinghouse for review by state agencies, the public review period shall not be less than 30 days, unless a shorter period is approved by the State Clearinghouse under Section 15105(d)." Therefore, the 30-day review period provided by the City of Tustin was in compliance with CEQA requirements. There are no provisions/restrictions for public review periods occurring during state or federal holidays. As was noted in the comment letter, interested parties were informed at the January 12, 2006, community meeting that public comments would be considered after the official close of the 30-day comment period until the City Council meeting for the project. 3. A lead agency is defined in Section 15367 of the State CEQA Guidelines as "the public agency which has the principal responsibility for carrying out or approving a project." The City of Tustin is the "Lead Agency" for the Rawlings Reservoir Replacement project. A minor component of the proposed project consists of street improvements along Foothill Boulevard, which require an encroachment permit from the County of Orange. Therefore, the County of Orange has only limited jurisdiction over the project and to the extent the encroachment permit process is discretionary, the County would be a Responsible Agency for purposes of CEQA. A notice of intent to adopt the MND was sent to the County of Orange; however, no comment letter was received. Should any input be received prior to the decision-making process, it will be considered. Pursuant to Section 15072(b) of the State CEQA Guidelines, the City of Tustin submitted the Notice of Intent to the "Iast known name and address" of the North Tustin Advisory Committee (NTAC). The NTAC is an advisory committee that serves the unincorporated area of Orange County which does not include the project site. The proposed project is not subject to review by NTAC. However, the City of Tustin, in good faith, elected to voluntarily present the proposed project to the NT AC at its regularly scheduled meeting on February 15, 2006. 4. As discussed in Response No.2 to the DTSC letter, MM 7-1 requires the City to prepare an Asbestos Management Program (AMP). While the precise details of the plan have not been finalized, the AMP would comply with the requirements of Rule 1403 and must incorporate the recommendations of the Asbestos and Lead Survey Report (Note that the Asbestos and Lead Survey is available for public review at the Community Development Department counter at Tustin City Hall). Rule 1403 is reproduced in its entirety and included as Attachment A, attached hereto and incorporated by reference herein. This Rule requires the City to notify the SCAQMD prior to demolition activity and sets forth specific reqUirements for the safe removal, transportation and disposal of asbestos from the project site. Moreover, various details of the proposed ACM removal are described in Response 2 to SCAQMD Comment Letter 4 and again repeated in Response 1 to Comment Letter 7.

As discussed in Section 5.1 of the IS/MND, Aesthetics, the proposed project (which includes implementation of landscaping) would not substantially degrade the existing visual character or quality of the site and no significant aesthetic impacts would result. Therefore, no mitigation is required. Preparation of the landscape plan will occur during final design and will be part of the Final Plans and Specifications to be considered by the City Council. 6. As noted in the responses for comments 1 and 2, the City of Tustin has processed a notice of intent to adopt an MND for the Rawlings Reservoir Replacement project in compliance with the requirements of CEaA. Subsequent project approvals by the City Council provide additional opportunities for the public to comment on more detailed aspects of the project. R.\Projects\Tuslin\JOO3\RTC-04060Etdoc Resolution No. 06-49 Page 122 of 171 2.10 Responses to Comments Comment Letter 7 Dear Mr. Reekstin: We attended the neighborhood meeting for your proposed water towers to be built where the Rawlings Reservoir currently sits. Our home sits directly above the reservoir and the Karetta home sits directly behind us. The following are just a few of our concerns: l I. The safe removal of the asbestos. Will the AQMD be mnnitnring the >- remnval? lfoot, why not? J The height of the tnwers. Although you state that they will be no higher than l the current structure, the fact that there are two of them makes the forward J 2 tower sit high out of the ground and is a huge concrete wall that did not exist before, Can you make one larger tower so it will sit further back on the lot and not be sueh a sore thumb? Can the sides of the tower/towers be more esthetic? ]- 3 You will be creating a huge blank canvas for graffiti. This can not be resolvedJ_ 4 with lighting the towers as that would be an even greater nuisance. One of my biggest concerns is the appearance of the structures from the top. Not only are the proposed roofs ugly, but the huge concrete flat area around the back and Y, of the front tower will create glare, heat, and would be visually ugly, We estimate the square footage of concrete and surface area nf the the top of the towers to be approx. 40,000 sq. ft, perhaps more. Can you verify this figure? You state that you need it for maintenance so trucks can drive on the concrete apron, but, this seems to be overkill. We wnuld rather see foliage from bushes, and a ladder on the side of the tower to reach the top for maintenance. This project will create dust, rodents, etc. for at least 2 years. How does the city plan on cleaning our bomes, cars, yards, etc? It is a major concern that the city of Tustin is the designer, approver and developer of the project. There is nn disinterested 3 nI party to grant approvals, permits, elc, We were all unaware that this island was part of The City of Tustin. Consequently, we, the neighbors, are disenfranchised. We have no city council to appeal to since we are in the county area and you have no government entity to watch over you and create a check and balance. The people most effected by this project have not real voice. I am quite certain that if a private developer were proposing sueh unappealing structures that would sit in the middle of the city, the planning department would be far mnre concerned with the esthetics and not just the function, If there were complaints about the project being made by city residents, the head of planning and the city council would sit up and Iislen. Furthermore, we are concerned that we gnt notification of our 30 days to make our views heard about the project on Dec. 20"'. Most of us were in the middle of celebrating the holidays until after New Year and consequently have had little time to digest the information gi ven us. 2. 3. 4, 5. 6. 7, These are just a few of our thoughts. Please respond 10 this letter as soon as possible. 1 5 }6 7 }. Resolution No. 06-49 Page 123 of 171 Thank You, Stephan and Robin Lang Earl Karetta Resolution No. 06-49 Page 124 of 171 Rawlings ResefYoir Replacement Project Responses to Comments Comment Letter 7 Stephan and Robin Lang Earl Karetta 1. Construction activities for the Rawlings Reservoir Replacement project are under the jurisdiction of the SCAQMD and all project-related construction activities, including demolition and structure removal, must comply with SCAQMD Rule 1403. In accordance with Rule 1403, SCAQMD would be notified of the asbestos removal prior to commencement of the demolition activity. The notification must include key components of the proposed removal which must be consistent with the health and safety procedures outlined in Rule 1403. In addition to compliance with Rule 1403, the Asbestos Abatement Contractor must comply with applicable regulations set forth by the Environmental Protection Agency, the Occupational Safety & Health Administration, and the Department of Health Services. An Asbestos Management Plan must also be prepared pursuant to Mitigation Measure 7-1. Asbestos removal work would be conducted in an isolated work area. Additionally, other engineering controls would be implemented which may include, but not be limited to, the use of High Efficiency Particulate Air (HEPA) filtration systems that would operate continuously from the commencement of work until the final clearance is achieved, wet removal methods, HEPA vacuums, and perimeter air sampling with on- and off-site analysis. Additionally, although not required, the project site would be monitored by an independent environmental consulting firm retained by the City to ensure compliance with the regulations set forth in SCAQMD Rule 1403. Should any form of non- compliance be observed, the independent consultant would immediately notify the City and the City would order the contractor to cease all ACM-removal activity until the non- compliance issue is resolved to the satisfaction of the City. To ensure this independent oversight occurs, the City will impose the following special condition: Haz-1 Prior to issuance of a demolition permit for the existing reservoir, the Community Development Department shall verify that the following requirement is included in the contractor specifications: An independent environmental consulting firm shall be retained and shall be onsite to monitor all removal/handling of asbestos containing material (ACM) conducted by the Asbestos Abatement Contractor, and to ensure compliance with SCAQMD Rule 1403. Should any form of non- compliance be observed, the independent consultant shall notify the City and the City shall order the contractor to cease all ACM-removal activity until the non- compliance issue is resolved to the satisfaction of the City. 2. Due to the size and shape of the project site (long and narrow), it is not possible to provide the necessary volume of water storage in a single circular tank; therefore, two tanks are required. The placement of the tanks on the project site is dictated by construction/engineering requirements. Nonetheless, as documented in the IS/MND discussion of the project's potential aesthetics impacts, the project has been designed to ensure that any visual or aesthetic impact would be less than significant. 3. As stated on page 5-1 of the IS/MND, the exposed portion of the front tank as well as non-paved areas of the site would be landscaped and the exterior of the exposed portions of the two tanks would receive coloration treatment to further screen and b"~nd the facilities with the proposed landscaping. It should be noted that the visual simulations of the proposed reservoirs that were presented at the January 12, 2006, community R 'IPrOjed$\T ustinUOO3IRTC-Cl4060S,doc 2-11 ~,&,gruf,!l'ncllfom~49 Page 125 of 171 Rawlings ReselVOir Replacement Project Responses to Comments meeting (which was attended by the commenter) represented the pre-landscape condition and were not intended to show the final visual characteristics of the project site. 4. During the construction phase, the police department would periodically patrol the project site. Additionally, during and after construction the project site would be fenced and locked to prevent trespassing and vandalism. It should also be noted that with landscaping of the exposed face of the reservoir tanks, access would be further deterred. 5. The roof area of the existing rectangular reservoir is approximately 38,000 square feet (sf). The roof area of the two new tanks would be approximately 28,200 sf, which is approximately 25 percent less hardscape than the existing reservoir. The perimeter area shown for reservoir access and maintenance would be approximately 22,500 sf. The combined areas of the new roofs and access area would be approximately 50,700 sf. A roadway for access to the roof of each tank is necessary for maintenance. As noted previously, the exposed portion of the front tank as well as non-paved areas of the site would be landscaped, and the exterior of the exposed portions of the two tanks would receive coloration treatment to further screen and blend the facilities with the proposed landscaping. As documented in Section 5.1 of the IS/MND, the project has been designed to ensure that any visual or aesthetic impact would be less than significant. It should also be noted that the location of ladders would not change the need for access of maintenance and inspection vehicles. Multiple roof hatches on each tank are required for safety and for personnel and equipment access, and paved access is necessary to each hatch location. 6. As stated on page 5-9 of the IS/MND, the project would be required to comply with applicable SCAQMD Rules and Regulations, including those related to dust control. Specifically, a fugitive dust control plan would be prepared and submitted to the City of Tustin Public Works Department and would be employed throughout project construction, including grading. With respect to concerns raised regarding rodents, residential areas do not provide sufficient natural resources for native wildlife species including but not limited to mice or other small animals that may inhabit the project site. In addition, project construction activity will largely be confined to currently disturbed areas as opposed to undeveloped densely vegetated areas that may provide shelter to rodents. There is no evidence that the project would create a significant rodent problem in this neighborhood. Therefore, no mitigation is required. It should also be noted that the City of Tustin would conduct a public outreach program throughout the construction phase of the project. As part of this program, surrounding residents would be notified of whom to contact during construction if they have any concerns/complaints. Specific concerns would be dealt with on a case-by-case basis. 7. A lead agency is defined in Section 15367 of the State CEQA Guidelines as "the public agency which has the principal responsibility for carrying out or approving a project." The City of Tustin is the "Lead Agency" for the Rawlings Reservoir Replacement project. The proposed project includes street improvements along Foothill Boulevard, which requires approval from the County of Orange before this component of the project can be initiated. Therefore, the County of Orange is a Responsible Agency. A notice of intent to adopt the MND was sent to the County of Orange; however, no comment letter was 2-12 Responses to Comments R. lProjecrs\ T ustlnUOO3\RTC..Q40600,doc Resolution No. 06-49 Page 126 of 171 Rawlings Reservoir Replacement Project Responses to Comments received.

Pursuant to Section 15072(b) of the State CEQA Guidelines, the City of Tustin submitted the notice of intent to the "last known name and address" of the North Tustin Advisory Committee (NTAC). The NTAC is an advisory committee that serves the unincorporated area of Orange County which does not include the project site. The proposed project is not subject to review by NTAC. However, the City of Tustin elected to voluntarily present the proposed project to the NTAC at the regularly scheduled meeting on February 15, 2006. The City of Tustin has solicited input from property owners in the area surrounding the project site and would continue to accept and consider comments from any interested parties. As noted previously, the City would implement a public outreach program for the project to maintain communication throughout the project design and construction phases. 8. Per CEQA Guidelines Section 15073(a), "the lead agency shall provide a public review period pursuant to Section 15105 of not less than 20 days. When a proposed negative declaration or mitigated negative declaration and initial study are submitted to the State Clearinghouse for review by state agencies, the public review period shall not be less than 30 days, unless a shorter period is approved by the State Clearinghouse under Section 15105(d)." Therefore, the 30-day review period provided by the City of Tustin was in compliance with CEQA requirements.

Construction activities for the Rawlings Reservoir Replacement project are under the jurisdiction of the SCAQMD and project-related construction activities, including demolition and structure removal, must comply with SCAQMD Rule 1403. In addition to compliance with Rule 1403, the Asbestos Abatement Contractor must comply with applicable regulations set forth by the Environmental Protection Agency, the Occupational Safety & Health Administration, and the Department of Health Services. Asbestos removal work would be conducted in an isolated work area. Additionally, other engineering controls would be implemented which may include, but not be limited to, the use of High Efficiency Particulate Air (HEPA) filtration systems that would operate continuously from the commencement of work until the final clearance is achieved, wet removal methods, HEPA vacuums, and perimeter air sampling with on- and off-site analysis. 2. As noted in Section 5.x1, Noise, construction-related noise would occur during the least noise sensitive daytime hours between the hours of 7:00 a.m. and 6:00 p.m. Monday through Friday, and between the hours of 9:00 a.m. and 5:00 p.m. on Saturdays. No construction activity would be allowed on Sundays or on City-observed federal holidays. In addition, a temporary sound barrier would be constructed, "residential grade" mufflers would be required on construction equipment, and construction hours would be prominently posted on the site to ensure that construction activity begins and ends at the hours specified above (see Special Conditions Noise-1, Noise-2, and Noise-3 as described on page 5-26 of the IS/MND). 3. Project construction activities would be in compliance with SCAQMD Rule 403, which imposes strict requirements on fugitive dust emission generation and control. The rules are especially restrictive in regards to dust control and do not allow any visible particulates to migrate off site. Section 5.11 of the IS/MND, Air Quality, indicates that no significant impacts would occur with implementation of the required mitigation (refer to MM 3-1). 4. Although not required, the project site would be monitored by an independent environmental consulting finn to ensure compliance with the regUlations set forth in SCAQMD Rule 1403. Should any form of non-compliance be observed, the independent consultant would immediately notify the City and the City would order the contractor to cease all asbestos containing material-removal activity until the non-compliance issue is resolved to the satisfaction of the City. As previously noted, the City has included a special condition for monitoring of compliance with SCAQMD Rule 1403. With respect to fugitive dust, on-site construction activities would be monitored on a daily basis by City staff. This would include visual monitoring to ensure that dust emissions are not dispersing to adjacent properties. Additionally, the City would implement a public outreach program for the project to maintain communication throughout the project design and construction phases. 5. See Response 6 to Comment Letter 7 regarding the project's potential to create a rodent problem in the neighborhood. 2-14 Responses to Comments R\PrOjeds\Tustin'JOO3\RTC-040606 doe Resolution No. 06-49 Page 130 of 171 Rawlings Reservoir Replacement Project Responses to Comments 6. Vibratory impacts associated with construction are usually due to either blasting or pile driving operations. Since this project does not incorporate either blasting or pile driving, no significant vibration impacts are anticipated. 7. As documented in the IS/MND, the project would have either no impact, a less than significant impact, or a less than significant impact with mitigation, for each environmental resource area evaluated in the IS/MND. There is no evidence that the project would result in any significant adverse impact on the structural integrity of any nearby residential or school property. Therefore, a pre-project, mid-project and early post-project assessment of nearby property is not required. B. As noted in Response No.7, there is no evidence that this project would have any potential impact on the health, safety, and welfare of vulnerable populations within the proximity of the project. The City would take all necessary precautions to ensure the adjacent sensitive receptors and property are adequately protected during project construction. In addition to ensuring that contractors comply with all applicable federal, state and local health requirements, additional measures would be incorporated into the project to address the potential impacts of the project. As documented in the IS/MND and its supporting technical data, all potentially significant impacts (most of which would occur on a temporary basis during construction only) would be mitigated to a less than significant level. These impacts include potential impacts from airborne asbestos and noise. Other construction related impacts, including impacts from construction emissions from heavy equipment and dust, would be less than significant. Pollutant emiS!lions generated during construction would be below applicable South Coast Air Quality Management District significance thresholds (see IS/MND, Table 4). Based on the conclusions of the IS/MND, there is no evidence that any injury or harm would occur to people or property in the vicinity of the project; therefore, implementation of the measures recommended in this comment, such as "ameliorative repair and reparations" and relocation of certain segments of the population in this area is not required under CEOA. 9. The comment is noted and will be taken into consideration by the decision makers.

Comments were noted during the meeting and are addressed below. A list of meeting attendees is provided following these responses to comments. Comment 1: Will residents receive assurance that Rule 1403 (concerning asbestos removal) be fully complied with? Response: Standard Condition 7-1 (page 5-18) of the IS/MND acknowledges that compliance with SCAQMD Rule 1403 (Asbestos Emissions From Demolitionl Renovation Activities) is required. National Econ Corporation, an independent environmental consulting firm, would have an experienced project technician on site full time to observe the asbestos removal conducted by the Asbestos Abatement Contractor and ensure compliance with Rule 1403. By law, the Asbestos Abatement Contractor must notify SCAQMD in writing of their intention to remove the asbestos 14 calendar days prior to the start of any abatement. This allows SCAQMD to make unannounced visits to the site at any time to ensure compliance. In addition to complying with Rule 1403, the Asbestos Abatement Contractor must at all times comply with Environmental Protection Agency (EPA) regulations, Occupational Safety & Health Administration (OSHA) regulations, Department of Health Services (DHS) regulations, and other regulations that apply to this project. National Econ Corporation's on-site technicians are rigorously trained in all aspects of asbestos project monitoring and would not hesitate to contact the City if any non-compliance is observed. Comment 2: Will the project be fully enclosed during asbestos removal? (Clarification of question No.1) Response: Asbestos removal work would be conducted in an isolated work area. Additionally, other engineering controls would be implemented which may include, but not be limited to, the use of High Efficiency Particulate Air (HEPA) filtration systems that would operate continuously from the commencement of work until the final clearance is achieved, wet removal methods, HEPA vacuums, and perimeter air sampling with on and off-site analysis. Comment 3: Do we know the name of the company who will be performing the asbestos removal? Response: The Asbestos Abatement Contractor has not yet been determined. The City of Tustin would put the project (design and construction) out for public bid. A component of this bid package is the asbestos removal specifications to be prepared by National Econ Corporation. Part of the bid process is a mandatory site visit by all the prospective Asbestos Abatement Contractors. This site visit would afford the prospective bidders the opportunity to see the project first hand and to ask any questions of the Independent Environmental Consultant who would be monitoring the project from commencement to completion. The prospective Asbestos Abatement Contractors would be issued a copy of the removal specifications outlining all regulatory requirements that would be rigorously enforced. The prospective bidders would then compile their bids for R.\ProjeclsITUSlinlJOO3\RTC-040006. doc Resolution No. 06-49 Page 132 of 171 2.16 Responses to Comments Rawlings Reservoir Replacement Project Responses to Comments submission no later than a date and time that would be determined by the City of Tustin. The City of Tustin would then begin a thorough review process of each bid to determine the eligibility and competence of each bidder. The City of Tustin would work closely with the Environmental Consultant during this review. At the end of the review process, the most qualified bidder would be given the City's recommendation for submission to the Tustin City Council for approval. If approval is authorized by the City Council, the project would be awarded to that bidder. A successful bidder will have demonstrated not only competitive prices, but experience with this type of project, a good safety record, adequate insurance, bonding, etc. Comment 4: Can local residents be notified of the name of the winning bidder? Response: The City of Tustin provides public notification of all City Council meetings, including agenda items. As noted above, the Final Plans and SpeCifications for the Rawlings Reservoir Replacement must be approved by the City Council and the recommended bidder would be included in the public notification for the City Council meeting. Comment 5: What about dust control? (From the School District, should they get special filters, change them more often, etc.?) Response: As stated on page 5-9 of the IS/MND, the project would be required to comply with applicable SCAQMD Rules and Regulations, including those related to dust control. Specifically, a fugitive dust control plan would be prepared and submitted to the City of Tustin Public Works Department and would be employed throughout the grading phase of project construction. Comment 6: Will there be any remediation or assistance to remove dust from houses, cars, and plants? Response: The only phase of construction that could generate significant dust emissions is the grading phase. However, as documented in the IS/MND (Table 3), with implementation of the extensive dust control measures set forth in Mitigation Measure 3-1, potential off-site dust emissions would be less than significant. Nonetheless, the City of Tustin would conduct a publiC outreach program throughout the construction phase of the project. As part of this program, surrounding residents would be notified of whom to contact during construction if they have any concerns/complaints. Specific concerns/complaints, including those associated with dust, would be dealt with on a case-by-case basis. Comment 7: When grading, what will be done regarding rodent infestation? Will this be remediated and how will this be accomplished? Response: See Response 6 to Comment Letter 7 regarding the project's potential to create a rodent problem in the neighborhood. Comment 8: Where will the noise barriers be placed? Describe the size of the barriers ,md the length of time the barriers will be in place. Response: The temporary noise barrier would be placed along the north and east property lines of the project site. The height of the barrier would initially be 24 feet tall as identified in Special Condition Noise-1 of the ISIMND. The barrier would be R.\Project8\Tu.tin\JOO3\RTC-040S06 doc 2-17 Rftrso4~1f8R?fcf."61f-49 Page 133 of 171 Rawlings Reservoir Replacement Project Responses to Comments installed prior to any demolition or grading and would remain in place until no longer required by construction activities. The deep excavation and associated shoring walls would provide noise attenuation and the height of the walls could be reduced during construction as appropriate based on the noise levels generated. Additionally, the later phases of construction might not include any significant noise generators, and the City could remove the barrier if this were the case. Comment 9: Will the noise barriers be placed around the homes? Response: The noise barrier would not be placed around the homes. As noted previously, the noise barriers would be placed along the north and east property lines of the project site. Comment 10: Clarify, will the barriers really be 24 feet tall? Response: As noted in Special Condition Noise-1 (page 5-26 of the IS/MND), the temporary barrier would be 24 feel high. Also refer to response to comment 8 above. Comment 11: Will there be any pile driving associated with this project? Response: No pile driVing is planned or required for the project. Comment 12: Are there any natural gas lines within the project limit area? Response: Available utility information indicates that there is a natural gas pipeline in Foothill Boulevard in front of the project site, but not on the site or in the access roadway along the easterly side of the site. Comment 13: Where will construction trucks access the job site and sit while waiting to access the site? Response: Construction vehicles would park along the curb of Foothill Boulevard while waiting to access the site. Construction vehicles would access the site from the existing access driveway and from a new driveway on the westerly front side of the site. Comment 14: Is the construction duration actually going to be 22 months? Response: Based on currently available project information, project construction is estimated to take approximately 22 months. Construction activities would include demolition of the existing reservoir; site clearing, excavation, and preparation for construction; new tank construction; site backfill; construction of pipelines and related improvements; site paving and landscaping; and final cleanup. The Final Plans and Specifications would provide a specific timeline for construction activities. Comment 15: Is the storm drain pipeline construction included in the original construction timeline? Response: Construction of the new drain line in Foothill Boulevard would take place within the same time period noted above for the proposed project. 2-18 Responses to Comments RIProjects\Tu,tinUOO3\RTC..o40606 doc Resolution No. 06-49 Page 134 of 171 Rawlings ReseNOir Replacement Project Responses to Comments Comment 16: Will there be security at the job site? Response: During the construction phase, the project construction site would be periodically patrolled by the police department. During construction and operation, the site would be fenced and locked restricting access into the site. Comment 17: What about graffiti control on the noise barriers and other portions of the job site? Response: As indicated above, the periodic patrols by the police department would be conducted. Should the noise barriers or other surfaces be vandalized with graffrti, the City would ensure that it is removed immediately which is consistent with city-wide policies. Comment 18: What is the target date for the MND to be presented to City Council? Response: Based on the current project schedule, it is expected that the MND would be presented to the City Council in April 2006. Comment 19: Citizens need more time and facts regarding the MND before it goes to Council. Can it be delayed? Response: Refer to the discussion of the public notification and review process for the IS/MND provided in Section 1.2 of this responses to comment document. Comment 20: Why isn't the asbestos plan completely in place before the MND goes to Council for approval? Response: The Asbestos Management Program (AMP) would not be prepared until the City selects the Asbestos Abatement Contractor. Nonetheless, no grading permit would be issued and no asbestos removal would occur until the AMP is prepared and SCAQMD is properly notified of the details of the removal plan. While the exact details of the AMP have not been defined, the AMP must include procedures that are consistent with the removal, transportation, and disposal procedures that are set forth in SCAQMD Rule 1403. Moreover the AMP would incorporate the recommendations of the Asbestos and Lead Survey that has already been prepared for the project. The Asbestos and l.ead Survey recommended the following measures to address ACM on site: a The AMP should set forth operation and maintenance guidelines to minimize fiber release which may be caused by age, normal wear and tear, delamination, building maintenance, repairs, renovation and other activities which may disturb ACM. . Prior to demolition, or major construction, specifications should be properly modified to incorporate the removal of ACM. . If removal of ACM is required in connection with demolition, renovation, or building repair, such work should only be performed by personnel who are appropriately trained, experienced, and registered. Intentional disturbance of ACBM should be performed in a manner such that emissions are controlled. Control measures should include, but not be limited to, wet methods, encapsulation, removal with HEPA-filter equipped vacuums, and R:\PrOjeetSITustinUOO3\RTC-040606.doc 2-19 Responses to Comments Resolution No. 06-49 Page 135 of 171 Rawlings Reservoir Replacement Project Responses to Comments appropriately labeled polyethylene bags. HVAC systems in work areas where asbestos is to be abated should be deactivated and the register closed and temporarily sealed. Air monitoring relating to such work should be performed by or under the direct supervision of a California State Certified Asbestos Consultant before, during, and after the abatement work, as required by EPA and other regulations. . California law requires a building owner to provide tenant, employee, and vendor notification within fifteen (15) days of receipt of information identifying the presence of ACBM in their buildings(s) and annually thereafter. Specific notification requirements are outlined in Assembly Bill 3713 and California Health and Safety Code 25915-2519.7. . There are potential liabilities associated with the presence and removal of ACM. Precautionary measures should be taken in accordance with the guidelines set forth by the EPA, the Occupational Safety and Health Administration (OSHA), and other regulatory agencies. Comment 21 : Will the new tanks be taller than the existing tanks? Response: As shown on Exhibit 7 of the IS/MND, the top of the new tanks would be only one foot higher than the roof of the existing reservoir. In addition, the new tanks would have roof vents and access hatches that extend slightly above the finished roof level. Comment 22: Can the City do something to make the roof of the reservoir more aesthetically appealing to the neighbors that look down on it? (e.g., sod roof) Response: For purposes of analysis, it has been assumed that the reservoir roof surface would consist of asphalt with a gravel coating. However, alternative roof treatments may be considered during the design process. The City would ensure that the roof treatment does not cause glare. Comment 23: What about expansive soil problems and potential damage to retaining walls, swimming pools, etc.? Response: The City's design engineer for the project is working with geotechnical engineers and shoring engineers to address the soils issue and to mitigate impacts to nearby retaining walls and swimming pools. Potential impacts related to unstable soils and expansive soils are addressed in Section 5.v1 of the IS/MND and would be less than significant with the implementation of current Uniform Building Code standards and standard engineering practices are used. Comment 24: What will be done to control/prevent graffiti on large walls that are exposed after construction is complete? Response: The project site would be fenced and locked, restricting access to the reservoir tanks. Additionally, as stated on page 5-1 of the IS/MND, the exposed portion of the front tank would be screened by landscaping. The visual simulations of the proposed reservoirs that were presented at the January 12, 2006, community meeting represented the pre-landscape condition and were not intended to show the final visual characteristics of the project site. 2.20 Responses to Comments R;\projects\T ustinUOO3\RTC-040606.doc Resolution No. 06-49 Page 136 of 171 Rawlings Reservoir Replacement Project Responses to Comments Comment 25: Will there be a process to ensure that the landscaping is maintained after completion of project? (Currently it has deteriorated.) Response: The City of Tustin would be responsible for maintaining the on-site landscaping. It should be noted that area immediately in front of the resefvoir site along Foothill Boulevard is currently owned and maintained by the County of Orange. With the proposed project, there would be improvements to Foothill Boulevard implemented in this area, including the introduction of a sidewalk and landscaping. Comment 26: Can the tanks be completely buried? Response: Completely burying the tanks is not feasible due to engineering, hydraulic, and public health and safety (e.g., water quality) constraints. Additionally, this method of construction would be cost-prohibitive. Comment 27: Is Tustin Unified School District being informed during all of these processes? Response: A copy of the Notice of Intent to adopt an MND was distributed to the Tustin Unified School District (TUSD). No comment letter was received. Additionally, the TUSD was invited to the informational community meeting held at Foothill High School. A representative from the TUSD attended this meeting and the NTAC meeting held on February 15, 2006. Comment 28: Is this meeting a 'Public Hearing"? Response: The meeting that took place on January 12, 2006, was an informational community meeting with the purpose of introducing the project to interested parties. It was not a public hearing. A public hearing would be scheduled to take place during a City of Tustin City Council meeting. Comment 29: Has NT AC been notified of this project and is being involved? Response: Pursuant to Section 15072(b) of the State CEQA Guidelines, the City of Tustin submitted the notice of intent to the "last known name and address" of the North Tustin Advisory Committee (NTAC). The NTAC is an advisory committee that serves the unincorporated area of Orange County which does not include the project site. The proposed project is not subject to review by NT AC, however, the City of Tustin has voluntarily presented the proposed project to the Committee at its regularly scheduled meeting on February 15, 2006. Comment 30: Is this project being "fast tracked"? Response: The proposed Rawlings Reservoir Replacement project is not being 'fast- tracked: The project is a Capital Improvement Program that is necessary to ensure sufficient water supply in the City service area. As discussed in Section 2.2 of the IS/MND, Project Background, the City initiated an evaluation of the proposed project in 1996 when an engineering analysis of the Rawlings Reservoir identified several structural deficiencies. The existing reservoir was taken out of service in 2004. Based on the current schedule, the City Council will consider approval of the MND and conceptual project design in April 2006, and required rate increase in May 2006. Subsequently, the City will solicit design/construction bids (Final Plans and SpeCifications) which, based on the R. \Projects\TullinUOO3\RTC.040606.dOc 2.21 Responses to Comments Resolution No. 06-49 Page 137 of 171 Rawlings ReselVoir Replacement Project Responses to Comments current schedule, would be considered by the City Council in Fall 2006. Construction activities are expected to be initiated in Spring 2007 and completed in Winter 2009. Comment 31: Who will issue the actual permits to perform the work? Response: The City of Tustin would issue permits to the contractor for on-site construction activities. The County of Orange and Orange County Flood Control District (OCFCD) would issue permits and other necessary approvals for street improvements on Foothill Boulevard and storm drain connections, respectively. Comment 32: Does the County oversee road closures and traffic control? Response: As indicated on page 5-28 of the IS/MND under item (a), the number of additional trips generated by the project during the construction phase would not significantly impact existing roadway operating conditions. However, MM 16-1 (page 5-31 of the IS/MND) requires submittal of Traffic Management Plans to the County of Orange for review and approval. Comment 33: Will there be enough aesthetical planning done? Will the area look better than it does currently? Response: As indicated on page 5-1 of the IS/MND, item (c), the existing visual character of the project site would be altered through the demolition of the existing reservoir and construction of two new reservoir tanks. The project has been designed to minimize aesthetic impacts through partial burial of the tanks and landscaping which is proposed for location along the exposed face of the front tank and on non-paved areas throughout the site. Comment 34: Will there be additional public meetings, say at the mid-point of the project and at the end for public input? Response: As noted previously, the MND and conceptual project design, and required rate increase will be considered by the City Council in April/May 2006. The Final Plans and Specifications for the proposed project would be considered by the City Council at a subsequent meeting. Additionally, the City of Tustin would implement a public outreach program for the project which could include periodic meetings to provide project updates and obtain input on the project. Comment 35: The City owns this "island" of land. When did this island appear and why? Response: The City of Tustin incorporated the reservoir site in the early 1980s when the City acquired Tustin Water Works and all of their privately held properties.
