TUSTIN LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPPLEMENTAL EIR CITY OF TUSTIN 1. Introduction Section 3. Revisions to the DuRELR. This section contains revisions to the DSEIR text and figures as a result of the comments received by agencies and interested persons as described in Section 2, and/or errors and omissions discovered subsequent to release of the DSEIR for public review. The responses to comments contain material and revisions that will be added to the text of the FSEIR. City of Tustin (City) staff has reviewed this material and determined that none of this material constitutes the type of significant neer information that requires recirculation of the DSEIR for further public comment under CEQA Guidelines Section 15088.5. None of this new material indicates that the project will result in a significant new environmental impact not previously disclosed in the DSEIR. Additionally, none of this material indicates that there would be a substantial increase in the severity of a previously identified environmental impact that will not be mitigated, or that there would be any of the other circumstances requiring recirculation described in Section 15088,5. 1.3 CEQA REQUIREMENTS REGARDING COMMENTS AND RESPONSES CEQA Guidelines Section 15204 (a) outlines parameters for submitting comments, and reminds persons and public agencies that the focus of review and comment of DSEIRs should be "on the sufficiency of the document in identifying and analyzing possible impacts on the environment and ways in which significant effects of the project might be avoided or mitigated. Comments are most helpful when they suggest additional specific alternatives or mitigation measures that would provide better ways to avoid or mitigate the significant environmental effects. At the same time, reviewers should be aware that the adequacy of an FIR is determined in terms of what is reasonably feasible.. , . CEQA does not require a lead agency to conduct every test or perform all research, study, and experimentation recommended or demanded by commenters. When responding to comments, lead agencies need only respond to significant environmental issues and do not need to provide all information requested by reviewers, as long as a good faith effort at full disclosure .is made in the EIR." CEQA Guidelines Section 15204 (c) further advises, "Reviewers should explain the basis for their comments and should submit data or references offering facts, reasonable assumptions based on facts, or expert opinion supported by facts in support of the comments. Pursuant to Section 15064, an effect shall not be considered signiftcant in the absence of substantial evidence." Section 15204 (d) also states, "Each responsible agency and trustee agency shall focus its comments on environmental information germane to that agetacys statutory responsibility." Section 15204 (e) states, "This section shall not be used to restrict the ability of reviewers to comment on the general adequacy of a document or of the lead agency to reject comments not focused as recommended by this section." In accordance. with CEQA, Public Resources Code Section 21092.5, copies of the written responses to public agencies will be forwarded to those agencies at least 10 days prior to certifying the environmental impact report. The responses will be forwarded with copies of this FSEIR, as permitted by CEQA, and will conform to the legal standards established .for response to comments on DSEIRs. Page 1-2 Phrre {V opb 2. Response to Comments Section 150$$ of the CEQ. I Guidelines requires the T.ead Agency (City of Tustin) to evaluate comments oil environmental issues received from public agencies and interested parties who reviewed the DSEIR and prepare written responses. This section provides all written responses received on the DSEIR and the City's responses to each comment. Comment letters and speciFtc comments are given letters and numbers for reference purposes. Where sections of the DSE1R are excerpted in this document, the sections are shown indented. Changes to the DSEIR text are shown in underlined text for additions and stj4keeti for deletions.

Response to Comments California Department of Transportation District 12, dated May 1, 2017. A2-1 The comment is introductory, including a description of the project. The comment does not address the adequacy of the DSEIR and no response is needed, Please note the reference to the 261 is SR -261 and reference to the 605 is not relevant since it is not near the project. A2--2 The commenter questions the traffic impacts to the ramps to and from the Interstate 5 (1-5) freeway at two streets. Specifically, the commenter questions whether development of 6,813 residential units and 239,797 average daily trips could only result in one vehicle existing the SB 1--5 during peak hours at the 'Tustin Ranch Road SB off -ramp. This DSEIR is a "Supplemental' EIR, its required pursuant to CEQA Guidelines Sections 15162 and 15163, the DSEIR focuses on Modified Project impacts determined to be potentially significant as compared to the previously adopted MCAS Tustin Specific Plan (Adopted Specific Plan), which was analyzed by the FEIS/EIR, For a further explanation of the approach and type of ETR, please refer to DSEIR Sections 1.1, lntrodflaion, 1.2.2 Iype and Purpose of this .S.FTR, 2,'1, Purpose of' the Enuironmental lv;pact Report, 2,33, Unavoidable S gnaficarntAdverre fmpacts, and 3,3, .Project_Baekground, The project trip distribution of 12 percent on Tustin Ranch Road south of Walnut Avenue as derived from the traffic model represents the distribution of the entirety of the trips to and from the Project area and does not translate into project trips being added to the baseline/no-project (i,e,, Adopted Specific Plan) results. The traffic model takes into account the proposed Project land use changes which affect the traffic patterns, both project -related and tion -project related, on the roadway system. Also both uses have opposite distribution patterns. For example, due to employment, residential trips are mostly outbound in the morning whereas non-residential trips are inbotuzd. The change in traffic patterns due to the land use differences between the Adopted and Proposed Specific Plan is the main reason that the reduction of non-residential and increase in residential uses show only incremental volume changes. Also note that the ITAM tnodel r7an assignments reflect how a roadway that is at or approaching capacity and becoming more congested, will result in trips distributing to other lower volume roadways in the network. Because of this, not all roadways in the study area would show similar increases due to the Project. A2-3 As detailed starting on Page A-107 of the Initial Study (Appendix A of the DSEIR), the Modified Project would not result in changes that would conflict with policies, plans or programs related to transit. The following transit bus services pass through or alongside the project site; me 20 17 Prize 2.9 TUST€N LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPPLEMENTAL EIR CITY OF TUSTIN 2.

Any increase in usage to the Tustin train station or demand for transit not realized by OCTA will be a local effort or collaboration with neighboring agencies depending on the need. A2-5 The comment recommends provision of additional bicycle support facilities including bike storage and bike signals. As hart of the City's General Plan, the City has a Bicycle and Pedestrian Plan that guides future development to include all users by providing bike lanes and bike detection wherever feasible, The City also conditions large employers to encourage non -vehicular modes of transportation by participating in Transportation 2 All routes frotil Orange.

Response to Comments _4k'l�I�rvil�B iifi4 Subject, Environmental Impact Report Tustin Legacy Specific Plan Amendment 2015-001 and General plan Amendment 2015-002 Dear Ms. Willkom� Thank you for the opportunity to comment on the above -noted projects ("Project"). The Adopted Specific Plan established a non-residential ADT cap of 182,851 ADT for trip budget and monitoring purposes based on trip rates established at the time (i.e., 2001 Final EtS1EIR)_ Residential unit trips are not included in that ADT cap. The Amendments to the Specific Plan proposes conversion and relocation of uses and the addition of 2,818 residential units beyond those in the Adopted Specific Plan such that the Project now proposes a total of 7,354 DUs. The Project also revises the non-residential trip rates used to calculate the non-residential ADT cap based on updated ITE rates. With the overall decrease in ITE trip rates between 2001 and current 2017 rates, particularly the significant decrease in ADT rate for "Community Commercial" (i.e., old rate of 68.17 ADTITSF now decreased to 42.7 ADTITSF), the Project proposes conversion of significant quantities of officeloffice park uses to community commercial uses in Neighborhood D, while staying within the non-residential ADT cap. Although within the non-residential ADT Cap, the Project as a whole including residential units, results in a net increase of 12,322 ADT. This 0SEIR and related traffic study analyzes the net ADT increase as well as the AM and PM Peak Hour periods to identify potential significant impacts resulting from the proposed uses, using the City's (TAM model (Version 12.4). The City of Irvine has reviewed the proposed amendments and has the following comments: A3-1 1 The Initial StudylNotice of Preparation (ISAVOP) for the Tustin Specific Plan Amendment reviewed by the City in 2015 discussed the Project's analysis of various A3 2 roadway circulation altematives including the extension of Moffett Drive to Tustin Ranch Road and to Carnegie, as well as a potential roadway through Tustin's PA8 Ju11e 201.7 Pwge 2-13 TUSTIN LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPPLEMENTAL FIR CITY 4F TUSTIN 2.

Response to Comments froin City of Irvine, dated April 19, 2017, A3-1 The comment is introductory, including the trip rates used for the Adopted Project and the Modified Project, and part of the traffic analysis conducted for the. Modified Project, Please note that the Nonresidential Land Use Trip Budget tracking system is separate from the average daily trips used to analyze traffic impacts in the FSEIR. As described in Section 3.4.1.3, Nonresidenliall_ind Use/Trip Brydget, the tracking system was developed as a mechanism for managing the forecast vehicular trips generated by the nonresidential land use mix in the Specific Plan area. In order to manage die availability of roadway capacity for the remaining, undeveloped land, the trip budget tracking systenx would continue to be monitored with the .Modified Projcct. Although all land uses are accounted for in the total average daily trips (AD'1) for the Modified Project, the trip budget applies only to nonresidential uses. The tracking system establishes a maximum limit on the ADT from, nonresidential uses for each neighborhood. That limit is identified in the trip budget, which summarizes the square footage of nonresidential uses in each neighborhood by planning area and the corresponding ADT. Implementation and administration of the trip budget is provided in Section 4.1.5, "Non-residential Land Use/Trip Budget," of the Specific Plan. Note that the commenter is correct that the City uses the most recent ITE trip generation irate to determine vehicle trips. As demonstrated on Table 5.7-4 of the DSFIR, the trip generation used to analyze traffic impacts associated with the Modified Project as compared to the Adopted Specific Plan incorporates all laud uses and would result in an overall net increase of 12,322 average daily trips. A3-2 The traffic analysis included an extension of Bell Avenue from Red Hill Avenue to Armstrong Avenue as a secondary arterial which is now referred to as Victory Road. As mentioned in the IS/NOP if needed, direct connection of this road between Armstrong Avenue and Tustin Ranch Road would be analyzed, but it was deemed not necessary. Also mentioned in the IS/NOP is Carnegie Avenue, as a discontinuous roadway, which in the analysis serves as a local collector roadway intersecting with Red Hill Avenue and Barranca Parkway. A3-3 Peter Anderson was contacted and the traffic modeling files utilized for the traffic analysis were forwarded by Stantec to his attention. A3-4 The internal trip capture percentage was based on the results of the ITAM Year 2035 Cumulative Conditions With 'Tustin Legacy Specific Plan Amendment using a special traffic modeling procedure referred to as it select -zone run in which project trips are isolated. In the select zone run using the traffic rrkodel, only the vehicular trips generated from the project zones are distributed onto the circulation system, Trips not distributed onto the circulation system are considered the project internal trip capture which are Jui%e 201 ! base 4"'! 7 TUSTIN LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPPLEMENTAL EIR CITY OF TUSTIN 2. Response to Comments trips that begin and end within the project site. The select -zone run showed that 10 percent of the project trips remain internal to the Specific Pian area. A3-5 The 2035 No Project and 2035 With Project ADT are based on separate ITAM Year 2035 Cumulative Conditions model run assignments. The trip distribution for the Project was developed based on the results of the ITAM Year 2035 Cumulative select zone run under the With Project conditions. The trip distribution shown in Figure 2-3 of the Traffic Study represents the distribution of the entirety of the trips to and from the Project site, which differs from the incremental increases due to the Project as seen by a comparison of Figures 5-1 and 5-2. The ITAM model run assignments reflect how a roadway that is at or approaching capacity and becoming more congested, will result in trips distributing to other lower volume roadways in the network. Because of this, not all roadways in the study area would show similar increases due to the Project. A3-6 The analysis of the arterial road system is based on intersection capacity since this is the defining capacity limitation on an arterial highway system. There can be exceptions in cases where certain facilities have long distances between signalized intersections, however, that is not the case for this study area. Therefore, peak hour intersection performance is the most representative measure for evaluating the study area arterial road system. Furthermore, the Irvine Link Analysis defers to peak hour data and the results of the impact analysis show that there are no project impacts at the Irvine intersections on a peak hour basis, As a result, the traffic study has not been revised to incorporate a roadway link analysis for roadways in the City of Irvine. A3-7 The commenter requests a phasing schedule and interim year scenario for the Modified Project in order to update ITAM. As stated in DSEIR Section 3.4,1,8, Phasing' Modified Project buildout is expected by 2035. The timing of specific developments under the Modified Project depends on market demand for planned land uses, the tithing of environmental cleanup work, and is currently unknown. Therefore, no DSEIR revision is required. However, assumptions on future approved project that should be included .in the ITAM interim year modeling conditions were forwarded to Deter Anderson. 'These assumptions are as follows: 0 TAZ 619 900 Students Heritage Elementary School (Buildout Enrollment) • TAZ 620 32,500 SF Learning Center/Institutional (AI'EP Phase 1) 0 TAZ 624 892 Students High School (1 /2 of buildout) • TAZ 643 390,000 SF Office.

IRWD requests thatthis source be clearly identified so IRWD understands whatthe reference source is A4-2 for this information, Information listed on pages 5.8-13 through 5.8-17 is inconsistent with other known IRWD data. For example, on page 5.8-14 under the Groundwater section, there is no mention of IRWD's Dyer Road We Ilfield from which most of the District's local groundwater supply is supplied. Additionally, within this same section, it is implied that groundwaterfrom the former Marine Corps Air Station -El Toro, which is contaminated with volatile organic compounds, is used for recycled water. This treated water is partof the District's non -potable supply. On page 5.8-15, underthe Non -potable Water section, this should he revised to the following_ "Non -potable watersources include recycled water, raw imported water, groundwater treated at the Shallow Groundwater Unit Treatment Plant and the Principal Aquifer Treatment Plant." Within the Recycled Water section on page 5.8-15, the last sentence in this paragraph should be revised to the following: "Same of the groundwateratthe Shallow Groundwater Unit Plant is used for irrigation purposes."

A4-1 The comnAent includes a notification that as developments tinder the Specific Plan are proposed, developers will be required to consult with IRWD for possible updates to the March .2017 Tustin Legacy Sub -Area Master Plan (SAMP) Amendment, The City concurs that notification will be forwarded to developers as needed. .A4-2 The commenter asks about a source cited as IRWD 2016 on DSEIR Page 5.8-13. The source is IRWD's 2015 Urban Water Management Plan issued iu 2016, as stated on Page 5.8-27. A4-3 The comment asserts that some of the statements on pages 5.8-13 through 5,8-17 are incorrect. The commenter states that Page 5.8-14 under the Groundwater section, has no mention of IRWD's Dyer Road Welifield from which most of the District's local groundwater supply is supplied, However, the sources of IRWD groundwater are accurately identified in the DSEIR as the Main Orange County Groundwater Basin, Irvine Subbasin, and rake Forest Subbasin. IRWD wells and wellfields are not identified in detail in the DSEIR, and such identification is not needed for understanding water sources. No DSEIR revision is required. The conunenter also states that the DSEIR implies that groundwater from the former Marine Corps Air Station -El 'Toro, which is contaminated with volatile organic compounds, is used for recycled water.

The proposed project consists of the zoning for the 1,606 -acre project area with a mixture of residential, commercial, commerciallbusiness, entertainment/recreation, and park land uses_ The City of Tustin is acting as the CEQA Lead Agency. This letter contains Metropolitan's continents to the potentially affected public agency. Metropolitan is a public agency and regional water wholesaler. It is comprised of 26 member public agencies serving approximately 19 million people in portions of six counties in Southern California, including Los Angeles County. Metropolitan's mission is to provide its 5,200 square mile service area with adequate and reliable supplies of bigh-quality water to meet present and future needs in an environmentally and economically responsible way. Metropolitan owns and operates the 79 -inch -inside -diameter East Orange County feeder No. 2 within the proposed project area. The East Orange County Feeder No. 2 originates at Metropolitan's Robert B. Diemer Treatment Plant in the City of Yorba Linda and transports treated water to the San Joaquin Reservoir in the City of Newport Beach, The East Orange County Feeder No. 2 within the proposed project area is located within public right-of-way of Red Hill Avenue and Barranca Parkway. Based on a review of the proposed project, the project has potential to impact Metropolitan's East Orange County feeder No. 2. Metropolitan must be allowed to maintain its rights-of-way and requires unobstructed access to its facilities in order to maintain and repair its system. In order to avoid potential conflicts Kith Metropolitan's facilities and rights-of-way, we require that any design plans for any activity in the area of Metropol'itan's pipelines or facilities be submitted for our review and written approval, Metropolitan will not permit procedures that could subject A5-2 700 N.

Any future design plans associated with this project should be submitted to the attention of Metropolitan's Substructures Team. Approval ofthe project should be contingent on Metropolitan's approval of design plans for portions of the proposed project that could impact its facilities. Detailed prime of drawings of Metropolitan's pipelines and rights-of-way may be obtained by calling Metropolitan's Substructures Information Line at (213) 217-7515. To assist the applicant in preparing plans that are compatible with Me )titan's facilities and casements, we have enclosed a copy of the "Guidelines for Developments in the Area of Facilities, Fee Properties, and/or Easement of The Metropolitan Water District of Southern California." Please note that all submitted designs or plans must clearly identify Metropolitan's faoilities and rights-of-way. In addition to potential impacts to Metropolitan's infrastructure, the DSEIR Chapter 5-08 analyzes water reliability and the California drought. This section references Metropolitan's 2004 and 2007 Integrated Water Resources Plan (TRP). A 2015 integrated Resources Plan is available and accessible on Metropolitan's website. Given the 3 year Governor -declared drought, the 2015 IRP must be analyzed in order to have an accurate understanding of current water reliability - We appreciate the opportunity to provide input to your planning process and we took forward to receiving future documentation and plans for this project.

Response to Comments AS. Response to Comments from Metropolitan Water District of Southern California (MWD), dated April 18, 2017. A5-1 The con-iment is introductory, including descriptions of the project and of the MWD, The cornment does not address the adequacy of the EIR and no response is needed. The commenter also provides attachments including a map and MWD's guidelines that have been incorporated into Appendix A of this FSEIR. A5-2 The comment states the project could impact MWD's East Orange County Feeder No. 2, a 79 -inch diameter pipeline extending in rights-of-way of Red I 1 Avenue and I3arranca Parkway; and that any plans for projects near MWD's pipelines or facilities trust be submitted to MWD's Substructures Team for review and approval. Please note that the following statement has been added to the Specific flan, "Projects proposed within the Tustin Legacy Specific Plan shall be consistent with the `Guidelines for Developments in the Area of Facilities, Fee Properties, and/or Easements of the Metropolitan Water District of Southern California.' All submitted designs and/or plans shall clearly identify MWD facilities and rights-of-way." Additionally, persons or entities conducting excavations trust request underground service alerts at least two days before the beginning of excavation pursuant to California Govertirnent Code Section 4216. Compliance with such Section would prevent excavation damage to the pipeline. A5-3 The continent notes that MWD has issued a 2015 Integrated Resources Plan (IRP), superseding 2004 and 2007 IRPs discussed in DSEIR Section 5.8, Utilities and Service ,Sjxtems, Please note that the Water Supply Assessment (WSA) for the Modified Project was adopted by the Irvine Ranch Water District (1RW1__)) on July 13, 2015. At that time, the 2015 IRP was not yet approved and the WSA relied upon the 2004, 2007, and 2010 IRPs to guarantee water supplies to the project. Furthermore, TRWD's approach to determining available water supply was conservative because it evaluated the percentage reduction of MWD' State Water Project (SAT) water supplies documented in the 2007 IRP of 22 percent (or 16 percent of overall water supplies) through 20 years. Total average MWD deliveries documented in the WSA were 1,968,000 acre-feet per year for a 20 year period (see Page 5.8-16 and 5.8-17 of the DSEIR).r The 2015 IRP reports an average supply reliability target for SLS P and Colorado River of 2,034,833 acre-feet for a 25 year; 1,134,833 acre-feet from SWP and 900,000 acre-feet from the Colorado River (see Table 6-1 of the 2015 IRP). The WSA relied on supplies less than those reported under the 2015, The WSA meets the requitements of CEQA Guidelines Section 15155, and no new impacts would occur. Total average 'CYIWI7 deliveries were calcul,,ltcd by using the average SSFP deliveries, applying a 22 percent redaction of SWP deliveries, and adding Colorado base average supplies (1,682,000 -370,000+656,000=1,968,000 Ai) jv„le 2017 Page 2-27 TUSTIN LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPPLEMENTAL EIR CITY 6F TUSTIN 2, Response to Comments Thie page inteniiowa j /it blank: llage 2.28 Pla,-470tks TUSTIN LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPPLEMENTAL EIR CITY OF TUSTIN 2.

The County oforange offers the following comments on the Draft Supplemental EIR - Tustin Legacy Specific Plan Amendment (CITY 2015.041) and General Plan Amendment (CITY 2015-002) R7 1 Flood Program Support reviewed the subject document and offers the following comments on I behalf of Orange County Flood Control District (OCFCD): I. The proposed project area is tributary to both Peters Canyon Channel (OCFCD Facility No. F06) and Barranca Channel (OCFCD Facility No. F09). These chamtels contain deficient A]_2 segments, The SEER should identify all OCFCD facilities that will potentially be impacted by the project. Z. Implementation of the revised land use and any new improvements to local drainage facilities have the potential to deliver more flows and affect OCFCD's facilities and will require appropriate analyses and mitigation ofpotentiai impacts. The City of Tustin (City) should A7-3 ensure the current General Plan Amendment is consistent with previously approved general plans. 3. Since the City is responsible for land use planning and development within City limits, the City should review and approve all local hydrology and hydraulic analyses including the needed 100 -year flood pit wetion for proposed changes to the developments within the project A7.4 area. Proposed flood protection measures should not worsen eeisling conditions or move flooding problems downstream or upstream of proposed developments. 4.

Response to Comments A7. Response to Comments from OC Public Works, dated April 27, 2017. A7-1 The comment is introductory in nature and does not address the adequacy of the EIR; no response is needed. A7-2 The comment identifies two OC Public Works channels the project site is tributary to — Peters Canyon and Barranca -- and states that both have deficient segments. Project site drainage, including the two identified channels, was described in the Initial Study on Page A-76 (Appendix A of the DSEIR). ids stated, major storm drainage channels and storm drains in and surrounding the site include Peters Canyon Channel extending through the eastern part of the project area; Barranca Channel along the southern site boundary; the Santa Ana --Santa Fe Channel just north of the north site boundary; and the Barranca Storin Drain in Red Hill .ilsenue along the west site boundary, Storm drains in the. part of the project area east of Peters Canyon Channel drain to Peters Canyon. Channel. The main storm drain systems onsite are in the western part of the site and drain to the Barranca Channel. Buildout of the Specific Plan Amendment would include development of a new drainage system for the site and would require improvements to Peters Canyon Channel, Barranca Channel along the south site boundary, and to the Santa ,Aria -Santa Fe Channel along the north site boundary. Projects developed pursuant to the Specific Plan Amendment would comply with requirements of the municipal stormwater permit (MS4 Permit, Order No. RS -2009- 0030) issued by the Santa Ana RWQCB, and the drainage area management plan issued by OC Public Works. Compliance with requirements of the aforementioned permit and plan, including LID requirements described above in Section 5.91b, would limit rates and volumes of runoff fromthe site. No new significant impacts associated with implementation of the Modified Project would occur. Furthermore, the cities of 'Tustin and Irvine and the Orange County Flood Control District entered into an agreement (D02-119) establislvng that the City of Tustin would be responsible for building infrastructure to support development of Tustin Legacy, including improvements to Peters Canyon Channel to accommodate 100 -year storm flows. The Peters Canyon Channel (Channel) improvement project from north of Edinger Avenue to the City limits north of Warner Avenue consists of widening of the channel on the eastern side and construction of a concrete channel lining. The project will also provide improvements to the pedestrian and bicycle trail on the east side of the channel. A.7-3 The comment states that Modified Project development could increase runoff impacts, including impacts to OCFCD (Onuige County Flood Control District) facilities. As stated starting on Page A-76 of the DSEIR (Appendix A), Specific Plan Amendment fpae 20 / 7 Pacg, 2-35 TUSTIN LEGACY SPECIFIC PLAN AMENDMENT FINAL SUPP! EMENTAL EIR CITY O; TUSTIN 2, Response to Comments implementation would involve construction of a network of new storm drains and would requireimprovements to three existing drainage channels, New I.ID requirements for infiltration, evapotranspiration, and/or runoff detention have been introduced since certification of the FINS/EIR. 'Thus, runoff rates and/or volumes from the site after buildout of the Specific Plan Amendment are expected to be less than would have resulted from biuldout of the Adopted Specific Plan, No new significant impact would occur, As part of the 2004 Master Runoff Management Plan for Tustin Legacy, described above, peak flow discharges and storm drain sizes were determined for each Planning Area based on their full buildout condition (commercial, residential, etc.). Prior to approval of individual projects within Tustin Legacy, the project must demonstrate that the proposed project peak flows are equal to or less than the ultimate condition peak flows in the master plan, For projects that will only occupy a portion of a Planning Area, the runoff management plan includes subareas with detailed hydrology calculations and peak flow limits to ensure the full buildout of .the Planning Area will remain within the total allowable discharge. This analysis is reviewed and approved by the City of Tustin. As part of the Tustin Legacy Specific Plan, several of the Planning Areas are subject to land use changes. "These changes include an overall increase in 2,212 residential units and an overall decrease in 1,755,306 square feet of commercial spread out over approximately 8 of the Planning Areas. The remaining Planning Areas will remain unchanged. The net increase in residential units will increase the net acreage of residential development, and the net acreage of commercial development wilt decrease. Commercial development is modeled at 90 percent impervious cover, and residential development is modeled at 80 percent (assuming high density) in accordance with OC Hydrology Manual parameters. Due to the conversion of commercial development to residential development, there will be a net overall decrease in impervious conditions in the Planning Areas subject to land use changes, The net decrease in impervious surfaces will result in a net decrease in pear flow runoff conditions. In addition, all projects built within 'Tustin Legacy will still be required to demonstrate that the project peak flow runoff is equal to or less than the assumed peak flow conditions associated with the 2004 Runoff Management Plan for Tustin Legacy. 'Therefore, there are no anticipated impacts related to hydrology based on the decrease in impervious conditions, the decrease in peak flows, and the requirement to confirm all project flows are within the established peak flow rates for the ultimate development condition. A74 As stated starting on Page A-78 of the DSEIR (Appendix .A), Peters Canyon Channel is mapped as a 100 -year flood zone (Lone .A) by FEMA. Much of the eastern half of the portion of the site in the City of Tustin is mapped as a 500 -year flood zone (Shaded Zone X) by FETNEA (FEMA 2009).

The City concurs that developments would comply with all such agreements in effect when the developments are proposed, Also see Response to Comment A7-2, No DSETR revision is required. A7-6 The comment states that work within QCFCD's rights-of-way would require County permits and should not adversely affect OCFCD facilities, Projects developed under the Modified Project would comply with such conditions.

Guidelines for Developments in the Area of Facilities, FOR Properties, and or Easements 0 i;,; Introduction a. The following general guidelines should be followed for the design of proposed facilities and developments in the area of Metropolitan's facilities, fee properties, and/or easements. b. We require that 3 copies of your tentative and final record maps, grading, paving, street improvement, landscape, storm drain, and utility plans be submitted for our review and written approval as they pertain to Metropolitan's facilities, fee properties and/or easements, prior to the commencement of any construction work. 2. Plans Parcel and Tract Ma s The following are Metropolitan's requirements for the identification of its facilities, fee properties, and/or easements on your plans, parcel maps and tract maps: a. Metropolitan's fee properties and/or easements and its pipelines and other facilities must be fully shown and identified as Metropolitan's on all applicable plans. b. Metropolitan's fee properties and/or easements must be shown and identified as Metropolitan's with the official recording data on all applicable parcel and tract maps. C. Metropolitan's fee properties and/or easements and existing survey monuments must be,dimensionally tied to the parcel or tract boundaries. d. Metropolitan's records of surveys must be referenced on the parcel and tract maps. -2- 3. Maintenance of Access Along Metro olitan's Rights-of-way a. Proposed cut or fill slopes exceeding 10 percent ase normally not allowed within Metropolitan's fee properties or easements. This is required to facilitate the use of construction and maintenance equipment, and provide access to its aboveground and belowground facilities. b. We require that 16 -foot -wide commercial -type driveway approaches be constructed on both sides of all streets crossing Metropolitan's rights-of-way. Openings are required in any median island. Access ramps, if necessary, must be at least 16 -feet -wide. Grades of ramps are normally not allowed to exceed 10 percent. If the slope Of an access ramp must exceed 10 percent due to the topography, the ramp must be paved. We require a 40--foot-long level area on the driveway approach to access ramps where the ramp meets the street. At Metropolitan's fee properties, we may require fences and gates. C. The terms of Metropolitan's permanent easement deeds normally preclude the building or maintenance of structures of any nature or kind within its easements, to ensure safety and avoid interference with operation and maintenance of Metropolitan's pipelines or other facilities. Metropolitan must have vehicular access along the easements at all times for inspection, patrolling, and for maintenance of the pipelines and other, facilities on a routine basis. We require a 20 -foot -wide clear zone around all above -ground facilities for this routine access. This clear zone should slope away from our facility on a grade not to exceed .2 percent. We must also have access along the easements with construction equipment. An example of this is shown on Figure 1. d. The footings of any proposed buildings adjacent to Metropolitan's fee properties and/or easements must not encroach into the fee property or easement or impose additional loading on Metropolitan's pipelines or other facilities therein. A typical situation is shown on Figure 2. Prints of the detail plans of the footings for any building or structure adjacent to the fee property or easement must be submitted for our review and written approval as they pertain to the pipeline or other facilities therein. Also, roof eaves of buildings adjacent. to the easement or fee property must not overhang into the fee property or easement area. 3 - e. Metropolitan's pipelines and other facilities, e.g. structures, manholes, equipment, survey monuments, etc. within its fee properties and/or easements must be protected from damage by the easement holder on Metropolitan's property or the property owner where Metropolitan has an easement, at no expense to Metropolitan. If the facility is a cathodic protection station it shall be located prior to any grading or excavation. The exact location, description and way of protection shall be shown on the related plans , for the easement area. Co Easements on Metropolitan's Property a. We encourage the use of Metropolitan's fee rights- of-way by governmental agencies for public street and utility purposes, provided that such use does not interfere with Metropolitan's use of the property, the entire width of the property is accepted into the agency's public street system and fair market value is paid for such use of the right-of-way. b.

The contractor will be liable for any damage to Metropolitan's facilities as a result of the construction. Paramount Right Facilities constructed within Metropolitan's fee properties and/or easements shall be subject to the paramount right of Metropolitan to use its fee properties and/or easements for the purpose for which they were acquired. If at any time Metropolitan or its assigns should, in the exercise of their rights, find it necessary to remove any of the facilities from the fee properties and/or easements, such removal and replacement shall be at the expense of the owner of the facility. 9. Modification of Metropolitan's Facilities When a manhole or other of Metropolitan's facilities must be modified to accommodate your construction or recons- truction, Metropolitan will modify the facilities with its forces. This should be noted on the construction plans. The estimated cost to perform this modification will be given to you and we will require a deposit for this amount before the work is performed. Once the deposit is received, we will schedule the work. Our forces will coordinate the work with your contractor. Our final billing will be based on actual cost incurred, and will include materials, construction, engineering plan review, inspection, and administrative overhead charges calculated in accordance with Metropolitan's standard accounting practices. If the cost is less than the deposit, a refund will be made; however, if the cost exceeds the deposit, an invoice will be forwarded for payment of the additional amount. - 10 - 10 . Drams a. Residential or commercial development typically increases and concentrates the peak storm water runoff as well as the total yearly storm runoff from an area, thereby increasing the requirements for storm drain facilities downstream, of the development. Also, throughout the year water from landscape irrigation, car washing, and other outdoor domestic water uses flows into the storm drainage system resulting in weed abatement, insect infestation, obstructed access and other problems. Therefore, it is Metropolitan's usual practice not to approve plans that show discharge of drainage from developments onto its fee properties and/or easements. b. If water must be carried across or discharged onto Metropolitan's fee properties and/or easements, Metropolitan will insist that plans for development provide that it be carried by closed conduit or lined open channel approved in writing by Metropolitan. Also the drainage facilities must be maintained by others, e.g., city, county, ham owners association, etc. If the development proposes changes to existing drainage features, then the developer shall snake provisions to provide for replacement and these changes must be approved by Metropolitan in writing. 11. Construction Coordination During construction., Metropolitan's field representative will make periodic inspections. we request that a stipulation be added to the plans or specifications for notification of Mr- of Metropolitan's Operations Services Branch, telephone 2 ) 250- , at least two working days prior to any work in the vicin ti y of our facilities. 12. Pipeline Loading Restrictions a. Metropolitan's pipelines and conduits vary in structural strength, and some are not adequate for AASHTO H-20 loading. Therefore, specific loads over the specific sections of pipe or conduit mast be reviewed and approved by Metropolitan. However, Metropolitan's pipelines are typically adequate for AASHTO 9-20 loading provided that the cover over the pipeline is not less than four feet or the cover is not substantially increased. If the temporary cover over the pipeline during construction is between three and four feet, equipment must restricted to that which imposes loads no greater than AASHTO H--10. If the cover is between two and three feet, equipment must be restricted to that of a Caterpillar D-4 tract --type tractor. If the cover is less than two feet, only hand equipment may be used. Also, if the contractor plans to use any equipment over Metropolitan's pipeline which will impose loads greater than AASHTO H-20, it will be necessary to submit the specifications of such equipment for our review and approval at least one week prior to its use. More restrictive requirements may apply to the loading guideline over the San Diego Pipelines 1 and 2, portions of the Orange County Feeder, and the Colorado River Aqueduct. Please contact us for loading restrictions on all of Metropolitan's pipelines and conduits. b. The existing cover over the pipeline shall be maintained unless Metropolitan determines that proposed changes do not pose a hazard to the integrity of the pipeline or an impediment to its maintenance. 13. Blasting a. At least 20 days prior to the start of any drilling for rock excavation blasting, or any blasting, in the vicinity of Metropolitan's facilities, a two-part preliminary conceptual plan shall be submitted to Metropolitan' as follows ; b. Part 1 of the conceptual plan shall include a complete summary of,proposed transportation, handling, storage, and use of explosions. c. Part 2 shall include the proposed general concept for blasting, including controlled blasting techniques and controls of.noise, fly rock, airblast, and ground vibration. 14. CEQA Requirements a. when Environmental Documents Have Not Been Pr.�ed 1) Regulations implementing the California Environmental Quality Act (CEQA) require that Metropolitan have an opportunity to consult with the agency or consultants preparing any environmental documentation. We are required to review and consider the environmental effects of the project as shown in the'Negative Declaration or Environmental Impact Report (EIR) prepared for your project before committing Metropolitan to approve your request. - 12 - In order to th the regulations implems entingCCEEQAcwhere Metroompliance politan the Lead Agency, the following minimumprocedures is not ensure compliance with the Act have beeestablished: a) Metropolitan shall be timely advised of any determination that a Categorical Exemption applies to the project. The Lead Agency is to advise Metropolitan that it and other agencies participating in the project have complied with the requirements of CEQA prior to Metropolitan's Participation. b) Metropolitan is to be consulted during the preparation of the Negative Declaration or EIR. C) Metropolitan is to review and submit any necessary comments on the Negative Declaration or draft EIR. d) Metropolitan is to be indemnified for any costs or liability arising out of any violation of any laws or regulations including but not limited to the California Environmental Quality Act and its implementing regulations. b. When Environmental Documents Have Seen Prepared If environmental dotliments have been prepared for your project, please furnish us a copy for our review and files in a "timely manner so that we may have sufficient time to review and comment. The following steps must also be accomplished - 1) The Lead Agency is to advise Metropolitan that it and other agencies participating in the project have complied with the requirements of CEQA prior to Metropolitan"s,parti.cipation. 2) You must agree to indemnify Metropolitan, its Officers, engineers, and agents for any costs or liability.arising out of any violation of any laws or regulations including but not limited to the California Environmental Quality Act and its implementing regulations. 15. Metro litan's Plan -Review Cost a. An engineering review of your proposed facilities and developments and the preparation of a letter response - 13 - giving Metropolitan's comments, requirements and/or approval that will require 8 man-hours or less of effort is typically performed at no cost to the developer, unless a facility must be modified where Metropolitan has superior rights. If an engineering review and letter response requires more than 8 man-hours of effort by Metropolitan to determine if the proposed facility or development is compatible with its facilities, or if modifications to Metropolitan's manhole(s) or other facilities will be required, then all of Metropolitan's costs associated with the project must be paid by the developer, unless the developer has superior rights. b. A deposit of funds will be required from the developer before Metropolitan can begin its detailed engineering plan review that will exceed 8 hours. The amount of the required deposit will be determined after a cursory review of the plans for the proposed development. C. Metropolitan's final billing will be based on actual cost incurred, and will include engineering plan review, inspection, materials, construction, and administrative overhead charges calculated in accordance with Metropolitan's standard accounting practices. If the cost is less than the deposit, a refund will be made; however, if the cost exceeds the deposit, an invoice will be forwarded for payment of the additional amount. Additional deposits may be required if the cost of Metropolitan's review exceeds the amount of the initial deposit. 16. Caution We advise you that Metropolitan's plan reviews and responses are based upon information available to Metropolitan which was prepared by or on behalf of Metropolitan for general record purposes only. Such information may not be sufficiently detailed or accurate for your purposes. No warranty of any kind, either express or implied, is attached to the information therein conveyed as to its accuracy, and no inference should be drawn from Metropolitan's failure to comment on any aspect of your project.

Metropolitan's records of surveys must be referenced on the parcel and tract maps. - 2 - 3. Maintenance of Access Along Metro olitan's Ri hts-of-Wa a. Proposed cut or fill slopes exceeding 10 percent are normally not allowed within Metropolitan's fee properties or easements. This is required to facilitate the use of construction and maintenance equipment, and provide access to its aboveground and belowground facilities. b. We require that 16 -foot -wide commercial -type driveway approaches be constructed on both sides of all streets crossing Metropolitan's rights-of-way. openings are required in any median island. Access ramps, if necessary, must be at least 16 -feet -wide. Grades of ramps are normally not allowed to exceed 10 percent. If the slope of an access ramp must exceed 10 percent due to the topography, the ramp must be paved. We require a 40 -foot -long level area on the driveway approach to access ramps where the ramp meets the street. At Metropolitan's fee properties, we may require fences and gates. C. The terms of Metropolitan's permanent easement deeds normally preclude the building or maintenance of structures of any nature or kind within its easements, to ensure safety and avoid interference with operation and maintenance of Metropolitan's pipelines or other facilities. Metropolitan must have vehicular access along the easements at all times for inspection, patrolling, and for maintenance of the pipelines and other,facilities on a routine basis. We require a 20 -foot -wide clear zone around all above -ground facilities for this routine access. This clear zone should slope away from our facility on a grade not to exceed 2 percent. We must also have access along the easements with construction equipment. An example of this is shown on Figure 1. d. The footings of any proposed buildings adjacent to Metropolitan's fee properties and/or easements must not encroach into the fee property or easement or impose additiohal loading on Metropolitan's pipelines or other facilities therein. A typical situation is shown on Figure 2. Prints of the detail plans of the footings for any building or structure adjacent to the fee property or easement must be submitted for our review and written approval as they pertain to the pipeline or other facilities therein. Also, roof eaves of buildings adjacent to the easement or fee property must not overhang into the fee property or easement area. - 3 - e. Metropolitan's pipelines and other facilities, e.g. structuress manholes, equipment, survey monuments, etc. within its fee properties and/or easements must be protected from damage by the easement holder on Metropolitan's property or the property owner where Metropolitan has an easement, at no expense to Metropolitan. If the facility is a cathodic protection station it shall be located prior to any grading or excavation. The exact location, description and way of protection shall be shown on the related plans for the easement area. 4. Easements on Metropolitan's Property a. We encourage the use of Metropolitan's fee rights- of-way by governmental agencies for public street and utility purposes, provided that such use does not interfere with Metropolitan's use of the property, the entire width of the property is accepted into the agency's public street system and fair market value is paid for such use of the right-of-way. b.

The location of utilities within Metropolitan's fee property and/or easement shall be plainly marked to help prevent damage during maintenance or other work done in the area. Detectable tape over buried utilities should be placed a minimum mum of 12 inches above the utility and shall conform to the following requirements: 1) Water pipeline: A two-inch blue warning tape shall be imprinted with: "CAUTION BURIED WATER PIPELINE' 2) Gas, oil, or chemical pipeline: A two-inch yellow warring tape shall be imprinted with: "CAUTION BURIED PIPELINE" 3) Sewer or storm drain pipeline: A two-inch green warning tape shall be imprinted with: "CAUTION BURIED PIPELINE" 4) Electric, street lighting, or traffic signals conduit: A two-inch red warning tape shall be imprinted with: "CAUTION BURIED CONDUIT* 5) Telephone, or television conduit: A two-inch orange warning tape shall be imprinted with: "CAUTION BURIED CONDUIT" - 8 - m. Cathodic Protection requirements: 1) If there is a cathodic protection station for Metropolitan's pipeline in the area of the proposed work, it shall be located prior to any grading or excavation. The exact location, description and manner of protection shall be shown on all applicable plans. Please contact Metropolitan's Corrosion Engineering Section, located at Metropolitan's F. E. Weymouth Softening and Filtration Plant, 700 North Moreno Avenue, La Verne, California 91750, telephone (714) 593-7474, for the locations of Metropolitan's cathodic protection stations. 2) If an induced -current cathodic protection system is to be installed on any pipeline crossing Metropolitan's pipeline, please contact Mr. Wayne E. Risner at ( 714) 593-7474 or ( 223) 250-5085'. He will review the proposed_ system and determine if any conflicts will arise with the existing cathodic Protection systems installed by Metropolitan. 3) Within Metropolitan`s rights-of-way, Pipelines and carrier pipes (casings) shall be coated with an approved protective coating to conform to Metropolitan's requirements, and shall be maintained in a neat and orderly condition as directed by Metropolitan. The application and monitoring of cathodic protection on the pipeline and casing shall conform to Title 49 of the Code of Federalf Regulations, Part 195. 4) If a steel carrier pipe (casing) is used: (a) Cathodic protection shall be provided by use of a sacrificial magnesium anode (a sketch showing the cathodic protection details can be provided for the designers information). (b) The steel carrier pipe shall be protected with a coal tar enamel coating inside and out in accordance with AWWA 0203 specification. n. All trenches shall be excavated to comply with the CAL/OSHA Construction Safety Orders, Article 6, beginning with Sections 1539 through 1547. Trench backfill shall be placed in 8 -inch lifts and shall be compacted to 95 percent relative compaction (ASTM D698) across roadways and through protective dikes. Trench backfill elsewhere will be compacted to 90 percent relative compaction {ASTM D698). 8. 9 - o. Control cables connected with the operation of Metropolitan's system are buried within streets, its fee properties and/or easements. The locations and elevations of these cables shall be shown on the drawings. The drawings shall note that prior to any excavation in the area, the control cables shall be located and measures shall be taken by the contractor to protect the cables in place. p. Metropolitan is a member of Underground Service Alert (USA). The contractor (excavator) shall contact USA at 1-800-422--4133 (Southern California) at least 48 hours prior to starting any excavation work. The contractor will be liable for any damage to Metropolitan's facilities as a result of the construction. Paramount Right Facilities constructed within Metropolitan's fee properties and/or easements shall be subject to the paramount right of Metropolitan to use its fee properties and/or easements for the purpose for which they were acquired. If at any time Metropolitan or its assigns should, in the exercise of their rights, find it necessary to remove any of the facilities from the fee properties and/or easements, such removal and replacement shall be at the expense of the owner of the facility. 9. Modification of Metropolitan's Facilities When a manhole or other of Metropolitan's facilities must be modified to accommodate your construction or recons- truction, Metropolitan will modify the facilities with its forces. This should be noted on the construction plans. The estimated cost to perform this modification will be given to you and we will require a deposit for this amount before the work is performed. Once the deposit is received, we will schedule the work. Our forces will coordinate the work with your contractor. Our final billing will be based on actual cost incurred, and will include materials, construction, engineering plan review, inspection, and administrative overhead charges calculated in accordance with Metropolitan's standard accounting practices. If the cost is less than the deposit, a refund will be made; however, if the cost exceeds the deposit, an invoice will be forwarded for payment of the additional amount. .. 10 10. Drainage a. Residential or commercial development typically increases and concentrates the peak storm water runoff as well as the total yearly storm runoff from an area, thereby increasing the requirements for storm drain facilities downstream of the development. Also, throughout the year water from landscape irrigation, car washing, and other outdoor domestic water uses flows into the storm drainage system resulting in weed abatement, insect infestation, obstructed access and other problems. Therefore, it is Metropolitan's usual practice not to approve plans that show discharge of drainage from developments onto its fee properties and/or easements. b. If water must be carried across or discharged onto Metropolitan's fee properties and/or easements, Metropolitan will insist that plans for development provide that it be carried by closed conduit or lined open channel approved in writing by Metropolitan. Also the drainage facilities must be maintained by others, e.g., city, county, ham<eowners association, etc. If the development proposes changes to existing drainage features, then the developer shall make provisions to provide for replacement and these changes must be approved by Metropolitan in writing. 11. Construction Coordination During construction•, Metropolitan's field representative will make periodic inspections. We request that a stipulation be added to the plans or specifications for notification of tele—ph—on—e--UM) ofM Metropolitan's Operations Services Branch, , at least two working days prior to any work in the vicinity of our facilities. 12. Pipeline Loading, Restrictions a. Metropolitan's pipelines and conduits vary 3m structural strength, and some are not adequate for AASHTO H-20 loading. Therefore, specific loads over the specific sections of pipe or conduit must be reviewed and approved by Metropolitan. However, Metropolitan's pipelines are typically adequate for AASHTO B--20 loading provided that the cover over the pipeline is not less than four feet or the cover is not substantially increased. If the temporary cover over the pipeline during construction is between three and four feet, equipment must restricted to that which ,imposes loads no greater than AASHTO $--10. If the cover is between two and three feet, equipment must be restricted to that of a Caterpillar D-4 tract --type tractor. If the cover is less than two feet, only hand equipment may be used. Also, if the contractor plans to use any equipment over Metropolitan's pipeline which will impose loads greater than AASHTO H-20, it will be necessary to submit the specifications of such equipment for our review and approval at least one week prior to its use. More restrictive requirements may apply to the loading guideline over the San Diego Pipelines 1 and 2, portions of the Orange County Feeder, and the Colorado River Aqueduct. Please contact us for loading restrictions on all of Metropolitan's pipelines and conduits. b. The existing cover over the pipeline shall be maintained unless Metropolitan determines that proposed changes do not pose a hazard to the integrity of the pipeline or an impediment to its maintenance. 13. Blasting a. At least 2D days prior to the start of any drilling for rock excavation blasting, or any blasting, in the vicinity of Metropolitan's facilities, a two-part Preliminary conceptual plan shall be submitted to Metropolitan as follows: b. Part 1 of the conceptual plan shall include a complete summary of.proposed transportation, handling, storage, and use of explosions. C, Part 2 shall include the proposed general concept for blasting, including controlled blasting techniques and controls of.noise, fly rock, airblast, and ground vibration. 14. CEQA Requirements a. When Environmental Documents Have Not Been Prepared 1) Regulations implementing the California Environmental Quality Act (CEQp,) require that Metropolitan have an opportunity to consult with the agency or consultants preparing any environmental documentation. We are required to review and consider the environmental effects of the project as shown in the Negative Declaration or Environmental Impact Report (EIR) prepared for your project before committing Metropolitan to approve your request. - 12 - 2) In order to ensure compliance with the regulations implementing CEQA where Metropolitan is not the Lead Agency, the following minimum procedures to ensure compliance with the Act have been established: a) Metropolitan any determination that applies to the project. advise Metropolitan tha participating in the p the requirements of CEQ participation_ shall be timely advised of a Categorical Exemption The Lead Agency is to t it and other agencies roject have complied with A prior to Metropolitan*s b) Metropolitan is to be consulted during the preparation of the Negative Declaration or EIR. c) Metropolitan is to review and submit any necessary comments on the Negative Declaration or draft EIR. d) Metropolitan is to be indemnified for any costs or liability arising out of any violation of any laws or regulations including but not limited to the California Environmental Quality Act and its implementing regulations. b. When Environmental Documents Have Been Prepared If environmental documents have been prepared for your Project, please furnish us a copy for our review and files in a timely manner so that we may have sufficient time to review and comment. The following steps must also be accomplished: - 1) The Lead Agency is to advise Metropolitan that it and other agencies participating in the project have complied with the requirements of CEQA prior to Metropolitan's.participation. 2) You must agree to indemnify Matropolitan, its Officers, engineers, and agents for any costs or liability.arising out of any violation of any laws or regulations including but not limited to the California Environmental Quality Act and its implementing regulations. 15. Metropolitan's Plan -Review Cost a. An engineering review of your proposed facilities and developments and the preparation of a letter response -- 13 .. giving Metropolitan's comments, requirements and/or approval that will require 8 man-hours or less of effort is typically performed at no cost to the developer, unless a facility must be modified where Metropolitan has superior rights. If an engineering review and letter response requires more than 8 man-hours of effort by Metropolitan to determine if the proposed facility or development is compatible with its facilities, or if modifications to Metropolitan's manhole(s) or other facilities will be required, then all of Metropolitan's costs associated with the project must be paid by the developer, unless the developer has superior rights. b. A deposit of funds will be required from the developer before Metropolitan can begin its detailed engineering plan review that will exceed 8 hours. The amount of the required deposit will be determined after a cursory review of the plans for the proposed development. C. Metropolitan's final billing will be based on actual cost incurred, and will include engineering plan review, inspection, materials, construction, and administrative overhead charges calculated in accordance with Metropolitan's standard accounting practices. If the cost is less than the deposit, a refund will be made; however, if the cost exceeds the deposit, an invoice will be forwarded for payment of the additional amount. Additional deposits may be required if the cost of Metropolitan's review exceeds the amount of the initial deposit. 16. Caution We advise you that Metropolitan's plan reviews and responses are based upon information available to Metropolitan which was prepared by or on behalf of Metropolitan for general record purposes only. Such information may not be sufficiently detailed or accurate for your purposes. No warranty of any kind, either express or implied, is attached to the information therein conveyed as to its accuracy, and no inference should be drawn from Metropolitan's failure to comment on any aspect of your project. You are therefore cautioned to make such surveys and other field investigations as you may deem prudent to assure yourself that any plans for your project are correct. - 14 17.

Plarelror'k J��-% NOTICE OF AVAILABILITY 10 DATE: March 16, 2017 TO: Agencies, Organizations and Interested Parties SUBJECT: Notice of Availability of a Draft Supplemental Environmental Impact Report in Compliance with Title 14, Section 15087(a) of the Callfornia Code of Regulations NOTICE 1S HEREBY GIVEN Pursuant to Public Resources Code Sections 21091 and 21092, and California Environmental Quality Act (CEQA) State Guidelines Sections 15105 and 15087, notice is hereby given that a Draft Supplemental Environmental Impact Report (DSEIR), State Clearinghouse No. 1994071005, for an amendment to the Tustin Legacy Specific Plan (formerly called the MCAS Tustin Specific Plan) and minor text amendment to the City's General Plan, the Modified Project, is available for public review during the public comment period (March 17, 2017 through May 1, 2017). The City of Tustin, as lead agency, has prepared the DSEIR to analyze environmental impacts associated with implementation of the Modified Project; to discuss alternatives; and to propose mitigation measures for identified potentially significant impacts that will minimize, offset, or otherwise reduce or avoid those environmental impacts. PROJECT TITLE: Tustin Legacy Specific Plan Amendment 2015-001 and General Plan Amendment 2015-002 PROJECT LOCATION: As shown in Figure 1, Vicinity Map, the project area for the Tustin Legacy Specific Plan (former MCAS Tustin), is in an urbanized area in the southern portion of the City of Tustin and the northwest portion of the City of Irvine in Orange County, California. The 1,606 -acre project area includes 1,511 acres in Tustin and approximately 95 acres in Irvine. The major roadways that border the site are Red Hill Avenue on the west, Edinger Avenue on the north, Harvard Avenue on the east, and Barranca Parkway on the south. Regional access to the project area is also provided by Jamboree Road/State Route 261 (SR -261) and State Route 55 (SR -55). DESCRIPTION: The WAS Tustin Specific Plan was adopted by ordinance on February 3, 2003, and established the zoning for the 1,606 -acre project area. It also established the necessary plans, development standards, regulations, infrastructure requirements, design guidelines, and implementation programs on which subsequent, project -related development is founded. It is intended that local public works projects, design review plans, detailed site plans, grading and building permits, or any other action requiring ministerial or discretionary approval applicable to the project area be consistent with the Specific Plan. The Specific Plan was amended six times between 2010 and 2014 in response to changing market conditions. The Tustin Legacy Specific Plan Amendment and general plan amendment will guide development of the remaining undeveloped area in the City of Tustin. These remaining parcels would be sold, leased, or developed by the City of Tustin. Eventually these parcels would be developed by a number of landowners within the framework established by the Specific Plan. The Specific Plan Amendment calls for a range of residential product types and education, commercial, commercial/business, entertainment/recreation, and park land uses. The proposed Specific Plan Amendment would change the mix and layout of land uses to be constructed in the project area. Land uses for 9 of the 22 planning areas in the project area would not be changed by the proposed project. Land uses in Planning Areas 1-7 and 20-22 would remain the same. As described in the Initial Study, the mix and layout of land uses Planning Areas 8-19 would change under the proposed project. Compared to the Adopted Specific Plan, the Specific Plan Amendment would allow ' NOTICE OF AVAILABILITY _t 2,212 additional homes and 1,755,306 fewer square feet of nonresidential building space. ENVIRONMENTAL DETERMINATION: The City of Tustin has completed a DSEIR for the Tustin Legacy Specific Plan Amendment and General Plan Amendment. The DSEIR analyzed impacts to eight environmental topical areas: Air Quality, Greenhouse Gas Emissions, Land Use and Planning, Noise, Population and Housing, Public Services (Schools), Transportation and Traffic, and Utilities and Service Systems. Mitigation measures have been adopted for air quality, greenhouse gas emissions, noise, and transportation/traffic, Pursuant to Public Resources Code § 21166 and CEQA Guidelines § 15162, the changes proposed by the Modified Project would not result in any new impacts, or increase the severity of impacts. Refer to Section 5.8.3 of the Initial Study (Appendix A of the DSEIR) for information on hazardous materials sites pursuant to Government Code Section 65962.5.
