SUBJECT: NEGATIVE DECLARATION FOR THE TUSTIN COMMUTER RAIL STATION
PARKING STRUCTURE
SUMMARY
The Tustin Commuter Rail Station Parking Structure project proposes the replacement of an
existing surface parking lot at the Tustin Commuter Rail Station with the construction of a parking
structure with up to 825 parking spaces on up to five levels. The project is a cooperative effort
between the Orange County Transportation Authority (OCTA) and the City of Tustin and is needed
to provide additional parking to serve the growing number of patrons of the Southern California
Regional Rail Authority's (SCRRA's) Metrolink commuter rail service. The OCTA will be
responsible for the design and construction of the project. A Final Negative Declaration has been
prepared for this project (Exhibit A of Resolution No. 07-83), and no potential significant
environmental impacts have been identified.
RECOMMENDATION
That the City Council adopt Resolution No. 07-83 approving the Final Negative Declaration as
adequate for the Tustin Commuter Rail Station Parking Structure project.
FISCAL IMPACT
The Tustin Commuter Rail Station Parking Structure project is a cooperative effort between the
Orange County Transportation Authority (OCTA) and the City of Tustin. The OCTA has secured
design and construction funding through the State Transportation Improvement Program in the
amount of approximately $10,600,000.
ENVIRONMENTAL
A Negative Declaration has been prepared in conformance with the California Environmental
Quality Act (CEQA) and is attached as Exhibit A of Resolution 07-83 (Attachment C).

BACKGROUND/DISCUSSION
The project site encompasses approximately 3.7 acres and is located at 2975 Edinger
Avenue (Attachment A -Location Map). The project site is surrounded by light
industrial, commercial, and automotive businesses to the northwest, west, and
southwest; Jamboree Road to the southeast, and railroad tracks and light industrial and
commercial uses to the north and northeast..
The site is zoned Planned Community -Industrial and is designated by the Tustin
General Plan as Planned Community Commercial/Business.
The proposed parking structure would be able to accommodate up to 825 parking spaces
and would be no greater than five (5) stories in height (approximately 50 feet in height).
No subterranean parking is proposed. The elevator/stair facility would extend
approximately 10-15 feet above the upper level of the parking structure. A conceptual
site plan of the proposed parking structure is provided in Attachment B.
Parking demand at the Tustin Commuter Rail Station already exceeds parking capacity
during peak hours and train ridership is anticipated to increase. The Orange County
Transportation Authority (OCTA) has adopted an increase in service plan for Metrolink
that would increase the frequency of train service between Fullerton and Laguna
Niguel/Mission Viejo to intervals of 30 minutes by 2009. The planned increase in train
service is expected to significantly increase parking demand. The proposed parking
structure would serve current demand and accommodate future demand caused by the
planned increase in train service.
The OCTA will be responsible for the design and construction of the project. To expend
the State Transportation Improvement Program funds for the design and construction, the
OCTA must first demonstrate that the City of Tustin has made an environmental
determination for the project pursuant to the California Environmental Quality Act.
Environmental Analysis
A Final Negative Declaration has been prepared for this project (Exhibit A of Resolution
No. 07-83). The attached Initial Study discusses potential impact categories. No
potential significant impacts have been identified. The public comments period for the
environmental documents was from October 18, 2007, to November 6, 2007. As of
October 30, 2007, no comments had been received.
ESTIMATED PROJECT SCHEDULE
It is anticipated that the Orange County Transportation Authority will complete the design
development and construction documents in October of 2009. Construction is proposed to
begin in May of 2010, with project completion scheduled for July 2011.

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 aproject-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, 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, an 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.
I. AESTHETICS -Would the project:
a) Have a substantial adverse effect on a scenic vista?
b) Substantially damage scenic resources, including, but not
limited to, trees, rock outcroppings, and historic buildings
within a state scenic highway?
c) Substantially degrade the existing visual character or
quality of the site and its surroundings?
d) Create a new source of substantial light or glare, which
would adversely affect day or nighttime views in the area?
II. AGRICULTURE RESOURCES: In determining
whether impacts to agricultural resources are significant
environmental effects, lead agencies may refer to the
California Agricultural Land Evaluation and Site Assessment
Model (1997) prepared by the California Dept. of
Conservation as an optional model to use in assessing impacts
on agriculture and farmland. 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?
b) Conflict with existing zoning for agricultural use, or a
Williamson Act contract?
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?
III. AIR QUALITY: Where available, the significance
criteria established by the applicable air quality management
or air pollution control district may be relied upon to make the
following determinations. Would the project:
a) Conflict with or obstruct implementation of the applicable
air quality plan?
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)?
d) Expose sensitive receptors to substantial'pollutant
concentrations?
e) Create objectionable odors affecting a substantial number
of people?

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?
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?
e) Conflict with any local policies or ordinances protecting
biological resources, such as a tree preservation policy or
ordinance?
f) Conflict with the provisions of an adopted Habitat
Conservation Plan, Natural Community Conservation Plan, or
other approved local, regional, or state habitat conservation
plan?
V. CULTURAL RESOURCES: -Would the project:
a) Cause a substantial adverse change in the significance of
a historical resource as defined in § 15064.5?
b) Cause a substantial adverse change in the significance of
an archaeological resource pursuant to § 15064.5?

EVALUATION OF ENVIRONMENTAL IMPACTS
TUSTIN COMMUTER RAIL STATION PARKING STRUCTURE
2975 EDINGER AVENUE
PURPOSE FOR THE PROJECT
The proposed project involves the development of a public parking structure to expand transit-
serving parking facilities at the Tustin Commuter Rail Station, which is located near the
intersection of Edinger Avenue and Jamboree Road. The project is needed to provide additional
long term parking to serve the growing number of patrons of the Southern California Regional
Rail Authority's (SCRRA's) Metrolink commuter rail service.
Parking demand at the Tustin Commuter Rail Station already exceeds parking capacity during
peak hours and train ridership is anticipated to increase. The Orange County Transportation
Authority (OCTA) has adopted an increase in service plan for Metrolink that would increase the
frequency of train service between Fullerton and Laguna Niguel/Mission Viejo to intervals of 30
minutes by 2009. The planned increase in train service is expected to significantly increase
parking demand. The proposed parking structure would serve current demand and accommodate
future demand caused by the planned increase in train service.
PROJECT DESCRIPTION
The Orange County Transportation Authority (OCTA), in cooperation with the City of Tustin,
proposes the construction of a parking structure with up to 825 parking spaces to replace an
existing surface parking lot at the Tustin Commuter Rail Station. The current parking capacity at
the station is approximately 317 spaces. The proposed project would include the demolition of
the existing parking lot and the construction of the new parking structure and driveway access.
Temporary off-site parking may be used during the -construction phase to accommodate
commuter rail patrons and/or construction workers. The location or locations of any temporary
off-site parking have not been determined at this time. However, temporary parking locations
would be within .5 mile of the site, and two locations within 500 feet of the site are being
explored at this time.
The Tustin Commuter Rail Station is located at 2975 Edinger Avenue. The 3.7 acre site is
surrounded by light industrial, commercial, and automotive businesses to the northwest, west,
and southwest; Jamboree Road to the southeast, and railroad tracks and light industrial and
commercial uses to the north and northeast.
The site is zoned Planned Community -Industrial and is designated by the Tustin General Plan
as Planned Community Commercial/Business.
Rail Station Parking Structure
Page 2
The proposed parking structure would be able to accommodate up to 825 parking spaces and
would be no greater than five (5) stories in height (approximately 50 feet in height). No
subterranean parking is proposed. The elevator/stair facility would extend approximately 10-15
feet above the upper level of the .parking structure. A conceptual site plan of the proposed parking
structure is provided in Exhibit 1.
The discretionary actions that are anticipated to be considered by the Tustin City Council include:
• Adoption of the Negative Declaration
• Approval of a cooperative agreement with the Orange County Transportation Authority
• Approval of the project design review
• Approval of the project plans and specifications
In addition, subsequent approvals by the City of Tustin may include:
• Demolition permit
• Grading permit
• Building permit
1. AESTHETICS
Items a & b - No Impact:
The 3.7 acre site is developed with an existing parking lot and rail station and is surrounded
by developed parcels. The property is not located on a scenic vista or within a State scenic
highway, thus would not damage scenic resources such as trees, rock outcroppings, or
historical buildings within a State scenic highway.
Mitigation Measures/Monitoring Required: None Required
Item c -Less Than Significant Impact:
The site is currently improved. The construction of a five-story parking structure would
change the visual character of the site and its surroundings, but would not degrade the visual
character of the site or its surroundings. The site is surrounded by a one and two-story
commercial buildings to the west, northwest, and southwest, Jamboree Road to the southeast,
and railroad tracks and light industrial and commercial buildings to the north and northeast.
No sensitive uses are located in the vicinity of the site.
It is assumed that the structure would be constructed in pre-cast concrete. Consistent with
the City's established procedures, architectural design details would be developed during
subsequent levels of project approval, including design review. Compliance with existing
design review criteria in the Tustin City Code will reduce any impacts to a level of
insignificance.

Mitigation Measures/Monitoring Required: None Required
Item d -Less than Significant Impact:
The project site is located in located in an urban setting that is currently subject to on-street
and on-site lighting. The existing commuter rail station and parking lot are lighted at night.
The proposed parking structure would introduce new light sources, but these light sources
would be consistent with existing light sources and would not adversely impact views in the
area. All light sources would be required to comply with the City's security standards and all
lights would be arranged so that no direct rays would shine onto adjacent properties.

2. AGRICULTURAL RESOURCES
Items athrough c - No Impact:
The proposed parking structure will be located on a site that is currently improved with an
existing commuter rail station and parking lot and surrounded by developed commercial and
light industrial properties, railroad tracks, and Jamboree Road. The proposed project is not
located on a property designated as Prime farmland, Unique farmland, or Farmland of
Statewide Importance, nor is it located within a property zoned for agricultural use, or a
Williamson Act contract; therefore, the project will have no impacts on any farmland, nor will
it conflict with existing zoning for agricultural use, or a Williamson Act contract. The proposed
project will not result in conversion of farmland to anon-agricultural use.

3. AIR QUALITY
Items a, c, d, and e - No Impact: The project is below the thresholds of significance
established by Tables 6-2 (operation thresholds) and 6-3 (construction thresholds) of the Air
Quality Management District's CEQA Air Quality Handbook. The Air Quality Management
Rail Station Parking Structure
Page 4
District's CEQA Air Quality Handbook is intended to provide professional guidance for
analyzing and mitigating air quality impacts of projects when preparing environmental
documents.
The construction of fewer than 1,309,000 square feet of building and the grading of fewer
than 177.00 acres is not considered to have a significant air quality impact. Since the total
building area will be approximately 250,000 square feet on 3.7 acres of land, no impact is
anticipated. As such, the proposed project will not conflict with or obstruct implementation of
any applicable air quality plan, violate any air quality standard, result in a cumulatively
considerable increase of any criteria pollutant as applicable by Federal or ambient air quality
standard, nor will it expose sensitive receptors to substantial pollutant concentrations, or create
objectionable odor affecting a substantial number of people.
Item b -Less Than Significant Impact:
The project will temporarily increase the amount of short-term emissions to the area due to
grading of the property and construction activities. Since the site is relatively flat, only minor
grading will be required. Less than significant short-term emissions associated with grading,
construction, and operation of the proposed project will comply with the regulations of the
South Coast Air Quality Management District and the City of Tustin Grading Manual, which
include requirements for dust control. As such, the proposed project will not create significant
impacts related to air quality.

4. BIOLOGICAL RESOURCES
Items athrough f - No Impact:
The site is improved and is surrounded by properties that are developed with pavement and
structures. The site is not inhabited by any sensitive species of animals and the proposed
project would have no impacts on animal populations, diversity of species, or migratory
patterns. No wetlands exist within the project site. The project would include the removal of
landscaping to accommodate the new parking structure, and new landscape materials will be
provided in accordance with the Tustin Landscape and Irrigation guidelines. No impacts to
any unique, rare, or endangered species of plant or animal life identified in local or regional
plans, policies, or regulations by the California Department of Fish and Game or U.S. Fish and
Wildlife Service would occur as a result of this project.

6. GEOLOGY & SOILS
Items a-ii, a-iii, & d -Less Than Significant Impact:
The proposed parking structure will be located on expansive soil and is located within an
area that may subject people or structures to strong seismic ground shaking and seismic-
related ground failure including liquefaction. However, a soils report is required to be
submitted prior to building permit issuance per the 2001 Uniform Building Code (or other
applicable building code) to demonstrate compliance with Chapter 18, which requires proper
excavation and fills for buildings, structures, foundations, and retaining structures, and
appropriate construction techniques to ensure seismic stability. No significant impact is
anticipated since the project would be conditioned to comply with the 2001 Uniform
Building Code related to Chapter 18 (or other applicable building code).

7. HAZARDS & HAZARDOUS MATERIALS
Items a through h - No Impact:
The proposed project consists of the construction of a parking structure. No storage or
transport of hazardous materials are anticipated from the proposed project. The project
would not result in exposure to hazardous substances. A parking structure is not anticipated
to emit hazardous materials which could create a hazard to the adjacent businesses or the
general public if released into the environment.
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 site is not listed as a hazardous materials site, is not located on any potential impact zones
identified for John Wayne Airport, and there are no private airstrips nearby. The project is not
anticipated to interfere with emergency response or evacuation. All grading and construction
is subject to compliance with all applicable Uniform Building and Fire Codes. As such, the
project is not anticipated to result in any significant hazards.
Mitigation Measures/Monitoring Required: None Required.

8. HYDROLOGY & WATER QUALITY
Rail Station Parking Structure
Page 7
Items a, b, c, d, e, k, 1, m, n & o -Less Than Significant Impact:
The project site is relatively flat, and the proposed project will continue to maintain a
relatively flat site with proper site drainage, including roads, curbs and gutters, and
landscaping. With new construction, there is the potential to impact stormwater runoff from
construction and post-construction activities with stormwater pollutants from the
maintenance of landscape areas and paved areas. There is also the potential for discharge of
stormwater to affect the beneficial uses of the receiving waters and changes in the flow
velocity or volume of storm water runoff. However, the project is required to comply with
the City's Water Quality Ordinance and most recently adopted NPDES permit (Santa Ana
Regional Water Quality Control Board (RWQCB) Order R8-2002-0010), thus reducing any
potential impacts to a level of insignificance. Together, these regulations minimize water
pollution by regulating point sources that discharge .pollutants into local waters. As such, the
project will not violate any water quality standards or waste discharge requirements or
degrade water quality in the area.
Mitigation Measures: None Required.
Sources: Field Verification
Conceptual Plans
Tustin City Code
Items f, , h, i, j and p - No Impact:
The project site is relatively flat, and the proposed project will continue to maintain a
relatively flat site with proper site drainage and landscaping. A portion of stormwater
received on-site will percolate into the soil where landscaping is provided, but the majority of
the stormwater will be conveyed through a fossil filter prior to entering a City stormdrain.
City stromwater infrastructure is able to accommodate the water from the project, and the
amount of water should not increase as a result of the project. The applicant must provide a
drainage and hydrology report to the City and demonstrate that the private stormwater
drainage system will be able to able to handle the capacity of any wastewater directed into
the system. Best Management Practices are required to be implemented for construction
activity and would deter water from flowing, off-site. Any water that would leave the site
would be filtered prior to entering a City storm drain. Best Management Practices will also
be implemented to ensure that, once the project is constructed, wastewater will be filtered
prior to entering the storm drain. As such, the project will not violate any water quality
standards or waste discharge requirements or degrade water quality, in the area.
While the project is located within Zone X (areas of 0.2 percent annual chance flood), the
project site is located outside a 100-year flood hazard area (areas of 1 percent annual chance
of flood) as mapped on a Flood Insurance Rate Map. Accordingly, the project will be
designed and graded with an appropriate drainage system to avoid any potential flood
hazards. The project is not located within a 100-year flood hazard area structure which will
impede or redirect flood flows. The project site will not expose people or structures to a

9. LAND USE PLANNING
Items a, b & c - No Impact:
The property is designated by the Tustin General Plan Land Use Map as Planned Community
Commercial/Business and zoned Planned Community Industrial (PC-IND). The proposed
project would not change the use of the property. The site is accessible from the City's
current street system, and the project would support existing transportation and public
facilities.
The proposed project would not divide an established community since it involves
construction on an existing site that is already improved with a parking lot and rail station.
The proposed project is not located in the conservation plan or natural community
conservation plan. The proposed project would not conflict with any applicable conservation
plan.
Mitigation Measures: None Required

11. NOISE
Items a through d -Less Than Significant Impact:
The maximum allowable noise level for industrial districts in Tustin is 70 dB(A). Exceptions
are made for noise sources associated with construction activities 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, excluding City observed federal holidays.
Construction of the proposed project would not occur beyond 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.
Furthermore, the proposed project would involve typical construction activities and
equipment. There would be no construction or operational activities that would generate
excessive groundborne vibration or noise.
Operations at the project site for the new parking structure would be similar to existing
conditions. The proposed project would not significantly increase ambient noise levels in the
project vicinity above levels existing without the proposed project.
Mitigation Measures/Monitoring Required: None Required
Sources: Conceptual Plans

12. POPULATION & HOUSING
Items athrough c - No Impact:
Rail Station Parking Structure
Page 10
The proposed project is the development of a parking structure for an existing commuter rail
station. No residential development is proposed. Implementation of the proposed project would
not result in a population increase in the City. In addition, no expansion of infrastructure would
be required which could indirectly induce population growth in the area.
The proposed project would not displace existing housing or people, nor require the
construction of replacement housing. The proposed project would not result in any impacts to
population and housing. Therefore, no mitigation is required.
Mitigation Measures/Monitoring Required: None required

13. PUBLIC SERVICES
Item a - No Impact:
The proposed project is a parking structure for an existing commuter rail station. The
proposed project is in an existing urbanized area where fire and police protection are
currently provided. Although the project would increase the number of parking spaces at the
commuter rail station, no new streets, public services, or infrastructure would need to be
created.
Mitigation Measures/Monitoring Required: None required
Sources: Conceptual Plans

15. TRANSPORTATION/TRAFFIC
Item a -Less Than Significant Impact; Item b - No Impact:
Rail Station Parking Structure
Page 11
The traffic analysis for this project is contained in the Traffic/Circulation Technical
Memorandum dated October 2007 prepared by PB Americas, Inc. (Exhibit 2).
Under aworst-case scenario, during the a.m. and p.m. peak periods the project is anticipated
to generate a total increase of 1,016 trips to roadways in the immediate vicinity of the
commuter rail station. Edinger Avenue at that location has a capacity of 48,600 vehicles per
day.
The traffic analysis concludes that the proposed project will not have significant adverse
impacts on the traffic circulation system. Each arterial and intersection projected to operate
at deficient levels of service, as demonstrated by comparing the No Project Scenario to the
Project Scenario, are impacted by presently assumed increased background traffic growth
surrounding the project area rather than prof ect-related traffic activity.
Items c, d, e, f & g - No Impact:
The proposed project will not induce substantial population or growth wherein the project
will not result in changes to air traffic patterns, or conflict with adopted policies, plans, or
programs supporting alternative transportation such as bus turnouts or bicycle racks. The
project will improve parking capacity and is proposed to satisfy current and future parking
demand at the Tustin commuter rail station. The project does not include any uses or design
features that would increase hazards. Furthermore, the parking structure would be designed
to ensure that adequate fire protection facilities are provided and that sufficient emergency
access is provided.
Mitigation Measures/Monitoring Required: None Required.

Traffic/Circulation Technical Memorandum (Exhibit 1)
16. UTILITIES & SERVICE SYSTEMS
Items athrough g - No Impact:
The proposed project will not exceed the requirements of the applicable Regional Water Quality
Control Board or require or result in the construction of new water or wastewater treatment
facilities. The proposed project will utilize the existing sewer and storm drain systems and thus
will not require construction of a new .storm water drainage facility or solid waste facility. The
project would be required to submit a hydrology report ensure proper grading, drainage, and
sewer systems. The project will utilize the City's existing trash hauler contract, thus not
requiring a new trash hauler. Adequate water supply from existing resources will be available to
serve the proposed project. Therefore, no environmental impact related to utilities and service
systems would occur, and no mitigation is required.
Mitigation Measures/Monitoring Required: None Required.

17. MANDATORY FINDINGS OF SIGNIFICANCE
Items a, b & c - No Impact:
The project design, construction, and operation will comply with applicable regulations. The
project, by nature of its location and as designed, does not have the potential to: degrade the
quality of the environment; reduce the habitat of 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. The project does not have the potential to achieve short-term environmental goals
to the disadvantage of the long-term. It does not have impacts that are individually limited
but cumulatively considerable or that would cause substantial adverse impacts on human
beings.

Traffic/Circulation
METHODOLOGY
The analysis for existing conditions was performed utilizing existing traffic counts obtained from the City
of Tustin and OCTA. For future conditions analysis, traffic volumes were obtained from the Orange
County Transportation Authority Model (OCTAM). OCTAM is the traffic forecasting tool for Orange
County.
The new parking structure will be designed to provide up to 825 new parking spaces. The structure is
sized to accommodate future parking demand estimates based on Metrolink ridership forecasts. The
structure is proposed as a multi-level parking unit replacing a portion of the existing 317-space surface
lot. The station site is accessible from Edinger Avenue. To accurately evaluate project impacts, the net
increase in parking spaces is the controlling factor in determination of trip generation associated with the
project. The new structure, an increase of 508 spaces over the existing 317-space surface lot, is forecast
to add 508 trips during each peak period and 1,016 daily trips to the immediate station vicinity circulation
system. This increase in volume creates a potential for traffic impacts. To estimate potential impacts
from the proposed project, arterial average daily traffic (ADT) and level of service (LOS) were analyzed
for the following ten arterial segments:
Walnut Avenue -Red Hill Avenue to Tustin Ranch Road
- Tustin Ranch Road to Jamboree Road
- Jamboree Road to Culver Drive*
^ Edinger Avenue- Red Hill Avenue to Tustin Ranch Road
-Tustin Ranch Road to Station Access
- Station Access to Jamboree Road
- Jamboree Road to Culver Drive*
^ Red Hill Avenue -Walnut Avenue to Edinger Avenue
^ Tustin Ranch Road -Walnut Avenue to Edinger Avenue
^ Harvard Avenue -Walnut Avenue to Edinger Avenue*
('` Denotes City of Irvine jurisdiction)
In addition, peak hour intersection LOS analysis was performed for the following twelve intersections
during morning (AM) and afternoon (PM) peak periods:
^ Red Hill Avenue / Edinger Avenue
^ Red Hill Avenue /Walnut Avenue
^ Tustin Ranch Road / Edinger Avenue
^ Tustin Ranch Road /Walnut Avenue
^ Edinger Avenue /Station Entrance
^ Edinger Avenue /Jamboree Road;
^ Walnut Avenue /State Route (SR)-261 Northbound (NB) Ramps*
^ Walnut Avenue / SR-261 Southbound (SB) Ramps*
^ Harvard Avenue /Walnut Avenue"
^ Harvard Avenue /Irvine Center Drive*
^ Culver Drive /Walnut Avenue*
^ Culver Drive /Irvine Center Drive*
(" Denotes City of Irvine jurisdiction)
Figure 3 presents the location of study arterial segments and intersections. OCTAM post-processing
methodology was applied to Year 2030 OCTAM forecast volumes to estimate future traffic volumes which
reasonably reflect appropriate growth consistent with existing traffic volumes. Arterial segment
performance was then evaluated by computing volume-to-capacity ratios (V/C), which are compared to
the City's critical thresholds to determine whether the arterial segment performs adequately. Similarly,
intersection performance was also evaluated by analyzing intersection capacity utilization (ICU) and
levels of service during the peak periods. The acceptable threshold is LOS D or better for both arterial
segments and intersections. Table 1 presents level of service thresholds.

Per the City of Tustin's traffic guidelines, if the daily V/C for a segment is equal to 0.91 or greater (i.e. LOS
E or worse), then a peak hour analysis for that segment must be performed to determine if there are any
peak hour deficiencies.
EXISTING CONDITIONS
The project area which encompasses the Metrolink Station is primarily comprised of light industrial and
commercial land uses. The station occupies a generally flat site of triangular shape and is bounded by
Jamboree Road on the East, Red Hill Avenue on the West, Walnut Avenue on the North, and the former
Tustin Marine Corps Air Station to the south.
~, Table 2 presents existing average daily traffic (ADT) counts and levels of service for key arterials
surrounding the project site. It is observed that under existing daily conditions, all segments with the
exception of two segments perform at a satisfactory LOS. Harvard Avenue from Walnut Avenue to Edinger
Avenue operates at LOS F. Table 3 reports AM and PM peak hour arterial segment levels of service for
the deficient arterial segment. The table indicates there are no capacity inadequacies for this arterial
segment during either of the peak hours.

FUTURE (YEAR 2030) NO PROJECT
Table 5 and Table 6 present daily and peak hour forecast volumes and levels of service, respectively, for
the arterial segments under future (Year 2030) No Project conditions. Three segments are projected to
operate deficiently under daily conditions. The traffic on Walnut Avenue between Jamboree Road and
Culver Drive is projected to increase by over 100 percent. Walnut Avenue from Tustin Ranch Road to
Jamboree Road is projected to increase by 28 percent. Harvard Avenue from Walnut Avenue to Edinger
Avenue is projected to increase by over 7 percent. These projected increases on these specific facilities
result in daily V/C ratios greater than the LOS D threshold. However, as shown in Table 6, the peak hour
analysis of these deficient segments indicated no capacity inadequacies during AM or PM peak periods.

FUTURE (YEAR 2030) WITH PROJECT
Table 8 presents daily forecast volumes and levels of service for the arterials under Future (Year 2030)
With Project conditions. The table indicates the three deficient segments remain unchanged compared to
No Project conditions. However, Edinger Avenue from Tustin Ranch Road to Culver Drive and Tustin
Ranch Road from Walnut Avenue to Edinger Avenue report a nominal V/C-increase of up to 0.02
compared to No Project conditions. Table 9 and Table 10 present LOS for AM peak hour and PM peak
hour for the deficient arterial segments. The tables reveal that all three segments perform satisfactorily at
LOS B or better during both peak periods in the future. The peak hour project-only trips are projected to
add an insignificant number of trips to the deficient segments during either peak hour and have a negligible
impact on their LOS.

under No Project conditions continue to operate deficiently under With Project conditions. As in the LOS
analysis of arterial segments, some intersections show a nominal increase in ICUs. The intersection of
Edinger Avenue/Station Entrance reports a V/C-increase of 0.05 during the AM peak hour and 0.02 during
the PM peak hour when compared to No Project conditions. However, as this intersection would continue
to pertorm at LOS A, no mitigation is warranted. The detailed ICU worksheets for this scenario are

Deficient Intersections -
CONCLUSION
The results of this analysis demonstrate that the parking structure project will not have significant adverse
impacts on the traffic circulation system. Each arterial and intersection projected to operate at deficient
levels of service, as demonstrated by the No Project to Project comparison, are impacted by presently
assumed increased background traffic growth surrounding the project area rather than project-related
traffic activity. No project traffic mitigation measures are warranted nor recommended for the proposed
parking structure project. Access issues associated with construction, if any, will be addressed in the
environmental document.
