A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY
OF TUSTIN RECOMMENDING THAT THE CITY COUNCIL
ADOPT A NEGATIVE DECLARATION PURSUANT TO THE
CALIFORNIA ENVIRONMENTAL QUALITY ACT FOR GENERAL
PLAN AMENDMENT 2013-002 (HOUSING ELEMENT UPDATE).
The Planning Commission of the City of Tustin does hereby resolve as follows:
The Planning Commission finds and determines as follows:
A. Implementation of the Housing Element Update's goals includes proposed housing
development within the MCAS-Tustin Reuse Plan area and infill areas outside the
Reuse Plan area throughout the City. Since the majority of future housing units
identified in the Housing Element Update would be located within the MCAS-Tustin
Reuse Plan area, an Initial Study was prepared to determine if impacts to the
environment of such housing were analyzed and addressed in the previously
approved Final EIS/EIR for the Disposal and Reuse of the MCAS Tustin (Program
EIS/EIR for MCAS-Tustin);
B. That on January 16, 2001, the City of Tustin certified the Program Final
Environmental Impact Statement/Environmental Impact Report (FEIS/EIR) for the
15 reuse and disposal of MCAS Tustin. On December 6, 2004, the City Council
adopted Resolution No. 04-76 approving a Supplement to the FEIS/EIR for the
NINE
extension of Tustin Ranch Road between Walnut Avenue and the future alignment of
Valencia North Loop Road. On April 3, 2006, the City Council adopted Resolution
No. 06-43 approving an Addendum to the FEIS/EIR. And, on May, 13, 2013, the
City Council adopted Resolution No. 13-32 approving a second Addendum to the
FEIS/EIR,"
C. The FEIS/EIR and its Supplement and Addenda is a program EIR under the
California Environmental Quality Act ("CEQA"). The FEIS/FEIR and its Supplement
and Addenda considered the potential environmental impacts associated with
development on the former Marine Corps Air Station, Tustin;
D. Pursuant to California Environmental Quality Act (CEQA) Guidelines Section
15063, the City of Tustin has completed an Initial Study (Exhibit 1) and determined
that all effects associated with the implementation of the Housing Element Update
were evaluated in the Program EIS/EIR for MCAS Tustin, that no new effects
would occur, that no substantial increase in the severity of previously identified
significant effects would occur, that no new mitigation measures would be required,
that no applicable mitigation measures previously not found to be feasible would in
fact be feasible, and that there are no new mitigation measures or alternatives
applicable to the project that would substantially reduce effects of the project that
have not been considered and adopted.
II. The Planning Commission of the City of Tustin does hereby find that the proposed project
is within the scope of the Final EIS/EIR for the Disposal and Reuse of MCAS Tustin
(Program EIS/EIR for MCAS-Tustin), an EIR approved from an earlier project, and that the
Resolution No. 4227
Page 2
-low
Program EIS/EIR for MCAS-Tustin adequately describes the general environmental setting M
of the Housing Element Update, the significant environmental impacts of the no
implementation of the Housing Element Update, and alternatives and mitigation measures
related to each significant effect.
Ill. The Planning Commission of the City of Tustin recommends that the Tustin City Council
adopt a Negative Declaration incorporating herein by reference all of the applicable
mitigation measures identified in the Program EIS/EIR for MCAS-Tustin.
PASSED AND ADOPTED at a regular meeting of the Tustin Planning Commission held on the

This Initial Study has been prepared io evaluate the potential environmental effects associated with the
adoption of the City of Tustin Housing Element Update. This iso revision bo the Housing Element that is
required by Government Code Section 65588 (b). This analysis has been conducted in compliance with
the California Environmental Quality Act (CE{3A) and Guidelines, as amended.
1.1 PROJECTLOCATION
The Regional Location Map (Figure 1) shows the location of the City of Tustin within the context of the
Orange County region. Tustin is located in central Orange County and is bordered byadeveloped,
unincorporated portion of Orange County (North Tustin) to the north, the City of Orange to the northwest.
Santa Ana to the west and southwest, and Irvine tothe south, south*ost, and east. The 55 Freeway
forms the majority of the City's western boundary, the 1-5 transects the southwestern area of the City, and
the Eastern Transportation corridor parallels the City's eastern border,
1.2 ENVIRONMENTAL SETTING
Existing Land Use
The City of Tustin is developed with e mix of commercial, industha|, and residential uses. The growth
trends in Tustin show significant population increases in the 1980s. followed by a s|mmn/ rate of growth
thereafter. From 1g8Oho1QQO. the City's population increased from 36.11Dtn5O.G8Q(4D.3 percent) and
from 2000 to 2010 population increased from 67.504 to 76.540 (11.9 percent). Recent projections
released by the Center for Demographic Research, CSUF (Orange County Projections 2010 Kdodified,
January 26. 2012) indicate that the City's population will increase by an annual roLo of 0.7% during this
Housing Element Implementation period. In 2012. the City's estimated population of 76,567 represented
2.5196 of Orange County's total population.
The California Department of Finance (DOF) estimated that in 2011, 24,945 households resided in Tustin,
and the average household size was 2.97 persons. Overo||, median resale home prices for zip codes in
the City of Tustin ranged from $36O.00Oto$478.O0Uin2O12.
According to Rea|Facts (a dotebonm publisher specializing in the housing rnarke\), the average rent for lioss°
the City of Tustin was $1.5S7 in the first quarter nf2U13. Tustin has a high percentage ofmulti-family
units compared to other Orange County communities. Approximately 35.1 percent nf the housing stock io
comprised of single-family attached/detached units while 61.5 percent of the housing stock consists of
multi-family units. AddiUone||y. Tustin has an almost equivalent number ofrenters and owners. In 2010'
50,8 percent of the housing stook was owner-occupied (48.7 percent of the population) and 49.2 percent
was renter-occupied (50.8 percent of the popu|aUun).
According to Table H-12 of the Housing Element Update. 19245 acres of vacant land with residential
development potential exists in the City of Tuatin, vvhi|o another 12.85 acres of !and with residential
development potential are underutilized. Based on established land use densities, this offers epotential
for 3O.18G total housing units in the City at build out capacity. Of the 1g2.45 acres of vacant land, 177.1
acres are |000bsd at the former MCAS'Tusdn and 15.35 acres are located generally in infi||
neighborhoods. The 12.85 acres of underutilized land are |uoutad generally in the Old Town area and
other underutilized land throughout the City.
The City of Tustin is required, per California Housing Element law, to meet its "fair share" of existing and
future housing needs for all income groups. An determined by the Southern California Association of
Governments (SCAQ). Tuntin's "fair share" is 1.227 additional units for the 2013-2021 planning period.
Based on the analysis of vacant land and underutilized land within the City, the majority of the required
housing units would be provided at Tustin Legooy, also known as the former Marine Corps Air Station
(MCAS) Tustin. Other housing units would be provided through infi|| developments within the nest of the
N
Tustin Legacy (former MC?��usti�n
Tustin Legacy is the portion of the former Marine Corps Air Station (MCAS) Tustin within the City of Tustin
corporate boundaries. Owned and operated by the Navy and Marine Corps for nearly 00 years,
approximately 1.585 gross acres of property at MCAS Tustin were determined surplus to federal
government needs and the base was officially closed in July 1Q9Q. The majority of the Tustin Legacy lies
within the southern portion of the City ofTustin. The approximately 73 acres lies within the City ofIrvine.
On January 16, 2001, the City Council adopted a General Plan Amendment to change the City's land use
designation for the former K4CAS-Tustin from Military and Public/Institutional to the MCAS Tustin Specific
Plan. The Specific Plan area is generally bounded by Edinger Avenue to the nodh. Harvard Avenue to
the east, Barranca Parkway to the south, and Red Hill Avenue to the west (Figure 2).
A Final Joint Environmental Impact Statement/Environmental Impact Report (FB8/E|R) for the Disposal
and Reuse of Marine Corps Air Station (KCAS) Tustin and Mitigation Monitoring and Reporting Program
for the E|5VBR was prepared by the City of Tustin and the Department of the Navy (DoN) in accordance
with the California Environmental Quality Act (CEQA) and the National Environmental Pn|icy(NEPA).
The FE|S/E|F< analyzed the environmental consequences of the Navy disposal and |000| community
reuse of the MCAS Tustin site per the Reuse Plan and the MCAS Tustin Specific Plan/Reuse Plan. The
CEQA analysis also analyzed the environmental impacts of certain "Implementation Actions" that the City
of Tustin and City of Irvine must take to implement the MCAS Tustin Specific Plan/Reuse Plan. The Final
E|S/E|R for the Disposal and Reuse of the former K8CAS-Tustin was certified by the City Council on
January 1G.2OO1. The DoN published its Record nf Decision (ROO)nn March 3.2OU1. On December 8.
2004. the City Council adopted Resolution No. 04-76 approving o Supplement to the FE|S/E|R for the
extension of Tustin Ranch Road between Walnut Avenue and the future alignment of Valencia North
Loop Road. On April 3, 2006, the City Council adopted Resolution No. 06-43 approving an Addendum to
the FE|S/E|R (herein after referred toes Program E|S/E|R for K4CAS'TusUn). And, on May. 13, 2013, the
City Council adopted Resolution Nn. 13-32 approving a second Addendum tothe FE|8/E|R,
The infill developments consist of utilizing vacant and underutilized land in other areas of City. The areas
include infiUneighborhoods primarily in the Old Town area and scattered infiU neighborhoods elsewhere
in the City (Figure 8).
Circumstances surrounding the implementation of the Housing Element Update at the former MCAS-
Tushn and in the |nO|l sites are essentially the same. In genexa|, these similar circumstances can be
summarized as follows:
• Housing units at the former K4CAS-Tustin would be developed in an urban setting
involving mixed land uses, similar to infill development in other areas of the City;
• Development ofhousing units at former the MCAS-Tustin and in@| sites will be required
to comply with the City's and State's existing nagu|eUone pertaining to air quality, noise,
water quality, construction standards, etc.
• The former MCAS-Tustin areas and infill sites will generally be served by the same utility
system: the former K4CA8-Tustin areas will be nerved by the Irvine Ranch Water District,
and infill sites will be served by the Orange County Sanitation District and Tustin Water;
• Both the fornnerK4CAG'Tuotin areas and infi|| sites will be served by the same public
service agencies such as Orange County Fire Authority, Tustin Police Department, Tustin
Parks and Recreation Department, etc.
• Children living in Tustin Legacy (former K4CAG-Tustin) wuu|d attend Tustin Unified and
Irvine Unified schools and children living in infiU aihan of Tustin would attend Tustin
Unified schools;
.
• Residents from the former K4CAS-Tustin and inDU sites would utilize existing and future
parks and recreational facilities awaUmbka to all City residents, etc,

1.3 PROJECT DESCRIPTION
L Proposed Project
The Housing Element is one of the seven General Plan Elements mandated by the State of California, as
articulated in Sections 65580 to 65589.8 of the Government Code. Skate Law requires that the Housing
Element consist of "an identification and analysis of existing and projected housing needs and e
statement of goa|s, polio|eo, quantified objootives, and scheduled programs for the preservation,
improvement and development of housing." The residential character of the City is, to a large ox1*nt,
determined by the variety ofits housing stook. its location and physical condition. The Housing Element
is. 1herofnre, on official municipal response to the need to provide housing for all economic segments of
the population.
The Housing Element Update provides in-depth analysis of the City's popubdion, economic, houooho|d,
and household stock characteristics as required by State Law. The Element also provides a
comprehensive evaluation of programs and regulations related to priority Qoa|s, oNwctives, and program
actions that directly address the needs of Tustin residents.
,
The City of Tusdn'a General Plan Housing Element and this Housing Element Update detail the City's
strategy for enhancing and preserving the community's chanacter, sets forth strategies for expanding
� housing opportunities for the Qty's various economics oegnlents, and provides the primary policy
�
guidance for local decision-making related to housing. The Housing Element Update provides the
implementation strategies for addressing the housing needs of Tustin residents through the 2013-2021
planning period.
As described in Section 1.2.1. the majority of the housing unite required by the Housing Element Update
would be provided at the former K4CAS-Tustin. Other units would be provided through scattered infi||
��.
developments within the City. As a result, the initial study prepared for the Housing Element Update
r
focuses primarily on the K4CAS-Tustin Specific Plan area. This is because the circumstances of the
^ KXCAS'Tusbn project studied in the Program E|B/E|R and the Housing Element Update project are
similar. TThe Final E|S/E|R for the Disposal and Reuse of the former MCAS-Tustin was certified by the
City Council on January 16. 2001. The DoN published its Record of Decision (ROD) on March 3, 2001.
On December 8. 2004. the City Council adopted Resolution No. 04-76 approving a Supplement to the
FE|S/E|R for the extension of Tustin Ranch Road between Walnut Avenue and the future alignment of
Valencia North Loop Road. On April 3. 2008, the City Council adopted Resolution No. 06-43 approving
on Addendum to the FE/S/BR (herein after referred to as Program E|S/E|R for K4CAG-Tustin). And. on
K1oy. 13. 2013. the City Council adopted Resolution No. 13'32 approving a second Addendum tothe
FE|8/E|R. A copy of the Program E|G/E|R for MCAG-Tustin and its supplement and addenda are
available for public review at the City of Tustin Community Development Department located at 300
Centennial VVoy, Tustin, California 92780. The Housing Element Update in only one facet of the City's
overall planning program. The California Government Coda requires that General Plans contain an
intognated, consistent set of goals and policies. The Housing Element is, thenefona, affected by
development policies contained in other elements of the General Plan.

11. Purpose ofInitial Study
As discussed inSection 1.1 (Project Location) most of the development of new housing units would take
place at the former MCAS-Tustin. The purpose of the initial study is to determine whether the Program
E|S/E|R for IVIC/\S-Tustin would adequately describe the project's general environmental setting,
significant environmental irnpacts, project alternatives, and mitigation measures related to each significant
impact. The initial study is also designed to determine whether there are any additional, reasonable
alternatives or mitigation measures that should be considered as ways of avoiding or reducing the
project's significant effects.
The City of Tustin is close to its build-out capacity. Opportunities to meet its "fair share" to build an
additional 1.227 housing units in the City largely depend on the availability of the former K4C/\S-Tustin
land. This land is the only significant area of vacant and underutilized land that is available in the City to
accommodate a large number ofhousing unite. Other vacant lands identified are infi|| sites scattered
throughout the City.
The Program BSVBR fbrK4CA5'Tustin identified several impact categories where significant impacts to
the environment onuk1 not be ndUgahnj to an insignificant level, and accordingly u Statement of
Overriding Considerations was adopted by the City of Tustin for approval of the General Plan Amendment
on January 1S.2OO1. For the purpose of this initial study, an evaluation has been made to ensure that
impacts previously identified no|uhng to this project has not been intensified. Program E|S/EIFl for K4CAS'
Tustin also identified onvane| impact categories where impacts could be lessened to o level of
insignificance with the imposition of mitigation measures. Each of these impact categories were analyzed
to determine if new impacts associated with the project would occur that were not identified in the
ProOramE|S/E|R.
Impact categories not identified to have a potential impact in the Program E|S/E|R forK4CAS-Tuotin have
been reviewed and identified in the inidel study to determine if the project would create any additional or
new significant impacts which were not considered by the Program E|S/E|Rfor MCAS-Tustin.
1.4 CITYACTION REQUIRED
The proposed action is the adoption of the Housing Element Update of the City's General Plan (the

2.3 EVALUATION OF ENVIRONMENTAL IMPACTS
A brief explanation is required for all answers except "No Impact" answers. The environmental checklists
2(A) from pages 12 — 24 and 2(B) from pages 25 — 36 are the starting point of the analysis. Checklist
2(/\) describes the environmental conditions related to infiU development sites throughout the Qb/ of
Tustin whereas checklist 2(B) refers to the conditions specific to the former MCAS — Tustin Specific Plan
area.
In Environmental Checklist 2(A), a "No Impact" answer and e "No Substantial Change from Previous
Analysis" answer in Environmental Checklist 2(B) is adequately supported if the referenced information
sources show that the impact simply does not apply ho projects like the one involved (e.g. the project falls
outside fault rupture zone). A"No Impact" answer inexplained where it is based on project-specific
factons, as well as general standards (e.g. the project would not expose sensitive receptors to pollutants,
based on8 project-specific screening ano|ysis).
All answers take account of the whole action invo|ved, including off-site and on-sihe, uunnu|otima and
project-level, indirect and direct, and construction and operational impacts.
Once the lead agency has determined that a particular physical impact may occur, and then the checklist
answers must indicate whether the impact is potentially significant, less than significant with mitigation, or
less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an
effect may be significant. If there are one or more "Potentially Significant Impact" entries when the
determination is made, anE|Flisrequired.
Earlier analyses may be used for subsequent activities if the effects of the project have been adequately
analyzed in m program BR. The Program BS/E|F( for &4CAS-Tustin has been reviewed to determine if it
is odnqueha for this project.
|n this case, a brief discussion should identify the following:
0 Earlier Analysis Used. Identify and state where they are available for review.
• 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 affects were addressed by mitigation measures based on the earlier
analysis.
• Mitigation Measures. For uffodo that are "Lees 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.
Lead agencies are encouraged to incorporate into the checklist nafnnnnoes to information sources for
potential impacts (e.Q. general plans, zoning ordinenoeo). Reference toa previously prepared oroutside
document should, where appropriate, include o reference to the page or pages where the statement is
substantiated.
Supporting Information Sources: A source list should be att8ohed, and other sources used or
individuals contacted should bn cited in the discussion.

3 Environmental Analysis
The previous Section 23 provided e checklist of environmental impacts. This section provides on
evaluation of the impact categories and questions contained in the oheoNial, and it identifies mitigation
measures vvAena applicable. Mitigation measures identified in the Program BS/BR for MCAS-Tustin
shall be implemented through implementation of the Specific Plan for the former MCAS-Tustin.
3.1 AESTHETICS
a) Have a substantial adverse effect mna scenic vista?
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings,
and historic buildings within o state scenic highway?
Development anticipated by the Housing Element Update would be located in mostly urbanized on*es
or areas that are planned to be urbanized that are not part of scenic vistas. No scenic vistas are
located in the vicinity of any proposed development locations such as, infill developments identified in
Table H-14 and Figure 1 of the Housing Element Update, and potential residential development at the
Tustin Legacy. Further. the City of Tustin does not contain any City- or County-designated scenic
highways. Thernfnna, implementation of the proposed project would not create significant impacts on
scenic vista, scenic resources, and scenic highway,

c) Substantially degrade the existing visual character nr quality ofthe site and its surroundings?
The proposed project provides for 1.227 units for development. The majority nf these housing units
would be constructed within the Tustin Legacy (MCASTustin Specific Plan). As each component of
the Specific Plan is deve|opod. there would be visual contrast created as previously undeveloped
land at the Tustin Legacy converts to urban uses or existing structures are demolished. The visual
quality of the project sites would be improved through application of the specific urban design
features such as |andsooping, as development occurs. Mitigation k4mesun* Vis-1 of the Program
EIS/EIR for MCAS-Tustin would provide measures to reduce the potential visual impacts to a level of
insignificance.
|n0| developments outside of the Tustin Legacy would be developed in accordance with the City's
Land Use Element and development standards and would not create a demonstrable negative
aesthetic effect tothe City's visual qualities. With the City's existing Design Review process that
requires specific findings for development compatibility with the sunnundingo, including height and
bulk of the bui|din0, exterior nnetnria|a and colors, |andsoaping, ehc., it is not anticipated that future
infi|| developments would create any significant visual impacts.

rU Create e new source of substantial light or glare, which would adversely affect day or
nighttime views in the area?
New development iD accordance with the City's Housing Element Update would create new sources
of light and glare such as exterior lighting, lighting of streets and walkways, and interior lighting which
38
3. Environmental Analysis
could be visible from the outside. However, the development would not result in any impacts beyond
those identified in the Program E|S/BR for MCAS-TueUn.
To minimize potential light and g!en* impacts for inUU dewa|opments, future development would be
required to comply with Tuatin's Security Ordinance. In addition. the lights and Q|une shall be
controlled through design controls and building ma&aho|s restrictions as part of the City's existing
Design Review process. The Design Review process requires specific findings to be made for
development compatibility with its surroundings including exterior illumination.
Mitigation Measures/Monitoring Required: No further mitigation measures would be required
beyond those identified in the Program E|S/E|R for MCAS'Tustin. which are hereby incorporated by
re#*nanoa.

3.2 AGRICULTURE RESOURCES
a) Convert Prime Fmnntmnd, Unique Farmland, or Farmland of Statewide Importance (Farmland),
as shown on the maps prepared pursuant bothe Farmland Mapping and Monitoring Program
of the California Resources Agency, to non-agricultural use?
According to the Farmland Mapping and Monitoring Program, the City of Tustin had Prime Farmland
located at the Tustin Legacy. The implementation uf the K8CAS Tustin Specific Plan would result ina
significant adverse effect of converting prime agricultural land to m variety of urban uses.
Approximately 289 acres of Prime Farmland would u|Unnmhe|y be developed with housing units. The ON
Program E|S/E|R for KXOAS-Tustin has provided detailed analysis of the a|Vamahvos and potential
mitigation measures and concluded that the impact isunavoidable.
Other available vacant or underutilized land within the City identified as potential land for residential
developments are not zoned or used for agricultural uses. Thenafore, no significant impacts to
farmland resources would result from the development of these infill lands.
The implementation of the Housing Element Update would potentially result in o significant impact of
converting agricultural iandto urban uses at the Tustin Legacy area. However, the implementation nf
the Housing E|annmnt Update would not result in any impacts beyond those identified in the Program
E|EBE|R for K4CAS-Tustin. No further mitigation measures would be required.
Mitigation MeasureslMonitoring Required: No mitigation measures were determined to be feasible
forK4CAS-Tuebn. A Statement nf Overriding Considerations was adopted.

3 Environmental Analysis
b) Conflict with existing zoning for agricultural use, ore Williamson Act contract?
The City of Tustin Genera/ Flan does not include any land designated for agricultural use.
Furthernlore. there is no land zoned solely for agricultural purposes or covered by a Williamson Act
contract in the City. The Williamson Act was adopted in 1965 and established a voluntary farmland
conservation p,mgnann which restricts contracted land to agricultural and/or open space uses for at
least ten years. Landowners who enroll their lands vvnu|d receive preferential tax treatment based on
the actual use of the land for agricultural purposes, as opposed to the unrestricted market value. The
previous interim agricultural uses at the former MCAS-Tustin have been discontinued since
preparation of the Program EIS/EIR for MCAS-Tustin, nor are infill developments areas within the City
under e Williamson Act contract.
Mitigation MeasureslMonitoring Required: No mitigation measures are necessary.

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?
The City of Tustin General Plan does not contain any land designated for agricultural use.
Furthernnoro, there is no land zoned solely for agricultural purposes. Except for those impacts
identified under Section 32 (o) above, there is no evidence or changes in the existing environment
which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use.

3.3 AIR QUALITY
a) Conflict with or obstruct implementation of the mpp|ioeb|o air quality plan?
b) Violate any air quality standard or contribute substantially to an existing or projected air
quality violation?
c) Result in o 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 that exceed quantitative thresholds for ozone
precursors)?
d) Expose sensitive receptors to substantial pollutant concentrations?
The Housing Element Update identifies an assigned fair share growth in the City for 1.227 new
housing units from 2013 '2021. According to the South Coast Air Quality Management District
CEQA Air Quality Handbook, the air quality impacts of the development of 1,227 dwelling units would
exceed the District's threshold ofsignificance. New development would generate pollutant emissions
due to new wshio|o thps, use of construction mquipnnent, and of-site power and natural gas
generation, During the construction phases of individual development pnojeuts, construction vehicles
and activities would also generate emissions. Air pollutant emissions associated with the project
could occur over the short-term for demolition, site preparation and construction activities to support
the proposed land use. In addiUon, emissions could result from the long-term operation of the
completed development.
EN
3 Environmental A l~" .
Short-Term Construction-Related Impacts
Short-term emissions are those occurring during the construction phases of individual developments
in the City. Air quality impacts may occur during the site preparation and construction activities
required to prepare the proposed on-site land use. Major sources of emissions during this phase
include exhaust emissions generated during demolition of an existing structure, site preparation and
subsequent structure enaction and fugitive dust generated as a result of soil disturbances during
excavation activities.
The Program E|8/E|R for K8CAS'TusUn identifies impacts that would result from the construction of
the housing units at the Reuse Plan area. To minimize these impada, future development projects
vvoukj be required to comply with specific construction oonhn| measures identified in mitigation
measure AC>'1 and AQ-2, if not already required by the G{|AO&4D Rule 403 related to wind
entrainment of fugitive dust. These mitigation measures are incorporated herein.
For infiU developments, the City will require compliance with A(JK4D Rule 403 related 0z air quality
construction control measures and the City's standard construction control measures (i.e. controlling
construction parking to minimize traffic interfe/ance, providing temporary traffic control during
construction activities to improve traffic flow, etc.). This would reduce air quality construction -related
impacts toe less than significant level.
Loncl-Term Air Quality Impacts
Long-term air quality impacts any those associated with the emissions produced from project-
generated vehicle trips as well as from stationary sources related to the use of natural gas for heating
and use of electricity for lighting and ventilation. The net increase in new development anticipated by
the Housing Element Update is na|ahad to a change in the number of housing units and additional
vehicle trips. rN
Long-term emissions from mobile (vehioukar) and stationary sources within the Reuse Plan area are
identified in the Program BS/E|R for K4CAS-Tustin as significant and unavoidable. Mitigation
nvaasuneAO-4 related to individual development's Transportation Demand KAanugemant(TDM) plan --
would reduce the innpant, but there are no feasible mitigation measures that will noduom the impact to
a less-than-significant level. A statement ofoverriding consideration was adopted.
Long-term emissions resulting from infiU developments are insignificant if developed individually but
could be significant cumulatively. These impacts shall be reduced through urban design planning as
suggested in the CEQA Air Quality Handbook prepared by the South Coast Air Quality Management
District (i.e. incorporation of bus turnoutS, pedestrian friendly site d*oign, provision for bike lanes,
etc.). Through the City's Design Review process, these design nnmasunao shall be determined on o
case-by-case basis as developments are proposed. Compliance with these measures would reduce
impacts related to long-term emission toa less than significant level.
Consistency with South Coast Air Basin (SCAB) Air Quality Management Plan (A IVIP)
The City's measures related to air quality for infill development and development of the Tustin Legacy
have been identified in the 2007 AQK4P prepared by the SCAQK4D. In sunlnlary, development
anticipated by the Housing Element Update is in compliance with the growth projections in the City's
Lend Use and Circulation Elements. The implementation of the Housing Element Update vvoukj
result in both short-term and long-term impacts. These impacts include construction-related impacts
associated with clearing and grading of the site and construction of building and infrastructure and
operational impacts attributable to air emissions from vehicular travel and generation of air
contaminants by the development. These impacts would not result beyond those identified in the
Program E|S/E|RfVr K4CAS-Tustin. No further mitigation measures would be required beyond those
identified in the Program E|S/E|R for K4CAS-Tustin.
|nh|| developments would be evaluated on an individual basis when the specific development is
proposed. Such development must comply with the City's Design Review process and would be
required to reduce potential impacts toa less than significant level. In addition, underCEQA. the
degree of specificity required in on environmental review corresponds to the degree of specificity

e) Create objectionable odors affecting a substantial number nfpeople?
Odors are one of the most obvious forms of air pollution to the Qanene| public. Odors can present
significant problems for both the source and the surrounding community. Although offensive odors
seldom cause physical hurnn. they can cause agitation, anger, and concern to the general public.
Most people determine an odor to be offensive (objectionable) if it is sensed longer than the duration
ofa human breath, typically 2to5seconds. The potential odors associated with the project are from
the application of asphalt and paint during construction periods. These odors, if perceptible, are
common in the environment and would baof very limited duration. |n addition, due to their nature as
residential housing units, no obnoxious odor would result from development of housing units identified
in the Housing Element Update.
Mitigation Measures/Monitoring Required: No mitigation measures are necessary.

b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community
identified in |moa| or regional plans, policies, regu|etions, or by the California Department of
Fish and Game orU.S. Fish and Wildlife Service?
o) Interfere substantially with the movement of any native resident mr migratory fish mrwildlife
species or with established native resident or migratory wildlife corridors, or impede the use

d) Conflict with any local policies or ordinances protecting biological reomurcea, such as a tree
preservation policy mrordinance?
e) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, qr other approved |oom|, regional or state habitat conservation plan?
Biological resources include plant and animal species and the habitats or communities within which
they occur. The implementation of the Housing Element Update consists of development within the
forn)aryWCAS'Tuntin and infi||areoo outside the fornlorK4CAG'Tustin area.
Impacts easnoiabad with Biological Resources within the former MCAS-Tustin area would occur atthe
construction phase for implementing the Rouse Plan development. In general, impacts can be
summarized as follows:
42
3 Environmental Analysis
yftgttation
ON-
Vegebainn in the Reuse Phan can generally be categorized as low quality cultivated fields or non-
native grassland. The agricultural fields on the former Air Station were regularly cultivated with row
crops, Because of the agricultural and historic military uses. the cultivated fields and landscaped
areas do not provide suitable habitat for rare plant species known from the region. In addition, the
Program FE|S/E|R determined that replacement ofthe agricultural fio|ds, non-native gnasa|and, and
ornamental landscaping with the development ofhousing units was not considered to be significant
because of the |ovv quality vegetation and past disturbances on the site. As such no mitigation
measure related to vegetation isnecessary.
Wildlife, Sensitive, Threatened, and Endangered Wildlife Species
Industrial, commercial, and residential land uses surrounding the Tustin Legacy and other vacant land
area typically would limit a site's value an wildlife habitat. The Program E|EKE|R for yNCAG-Tustin
identified Southwestern Pond Turtle, "species of special concern," within the K8CA8 boundary;
hovvever, based upon the analysis in the Program E|S/E|Fl, the sighting was found within areas
identified for development of nnmnnemio| and oornnneroio| businesses. TharefUne, no impact to
southwestern pond turtle habitat would result from the implementation of the Housing Element
Update at the former K4CAS'Tustin. Nevertheless, Mitigation measures were included in the Pnognsnn
FEIS/EIR to require the relocation of the turtles and establishment of an alternative off-site habitat, and
to require the applicant to obtain Section 404, Section 1601, and other permits as necessary for areas

3.5 CULTURAL RESOURCES
aU Cause a substantial adverse change in the significance of a historical resource as defined in
§15884.5?
Section 10564.5 defines historic resources as resources listed or determined to be eligible for listing
by the Gtoha Historical Resources Cnnnnn|an|on. a local register of historical resources, or the lead
agency. Generally a resource is considered to be ^hiotnhugUy significant," if it meets one of the
following criteria:
i Is associated with events that have made a significant contribution to the broad patterns of
California's history and cultural heritage;
|s associated with the lives nf persons important in our past;
Embodies the distinctive characteristics of type, period, /egion, or method of construction,
or represents the work of an important creative individual, or possesses high artistic values;
or
iv. Has yielded, or may be likely to yield, information important in prehistory or history (§15064.5)
The nxa��r�y of the construction of residential units described in the Housing Element Update would
occur at Tustin Legacy. The Program FBS/E|R identified two discontiguous o|kJib|e historic districts
in which two hangars are |000bad in Tustin Legacy as historic resources. Pursuant to Section 108.
the State Historic Preservation, the Advisory Council on Historic Preservation, the Navy, the City of
Tustin, and the County of orange executed e Memorandum of Agreement (K8OA) that identifies
nnoenunen to mitigate the effects of the destruction of portions of the eligible historic district, including
the hangars. If financially feasible for adaptive n*uoe, both blimp hangars would be preserved.
However, if it is determined that it is not financially feasible to retain either of the hangars, removal of
the hangars was determined to be a significant unavoidable impact pursuant to CEQA. There isno
new technology ormethods available to reduce the identified significant unavoidable project-specific
and cumulative impacts to historical resources hoa level considered less than significant. Thanefone,
these unavoidable project-specific and cumulative impacts also occur with development of housing units
at Tustin Legacy. A Statement of Overriding Consideration for the FEIS/EIR was adopted by the Tustin
City Council on January 16. 2001. to address potential significant unavoidable impacts to historical
resources resulting from the removal of the historic resources. No substantial change for MCASTustin
is expected from the analysis previously completed in the FEIS/EIR, its Supplement and Addenda.
{n8U developments may occur within the City's designated Cultural Resources Overlay District.
Development within this district is required to comply with development standards in the Zoning Codo,
including a Design Review process in the District. The Design Review process requires specific
findings to be nnodn to ensure the proposed design in compatible and consistent with the City's
Cultural Resources District design uhtehe and development standards. Compliance with the City's
Design Review and Certificate ofAppropriateness procedures would reduce potential impacts too
level nfinsignificance.

b) Cause a substantial adverse change in the significance of an archaeological resource
pursuant to@15O64.5?
Impacts to archeological sites are considered significant only if the sites themselves are deemed
significant. The majority of the housing development identified in the Housing Element Update would
be located in the Tustin Legacy. To determine if there are any archeological sites located in the
Tustin Lagony, various surveys were conducted. In summary, one archeological site was recorded
but it is believed to have been destroyed. The State Historic Preservation Office (GHP[)) has
concurred with the assessment that the site has been adequately surveyed and the site has been
considered to be insignificant due to its lack of integrity. Thenefona, there would not be an adverse
effect on the one known archeological resource in the Tustin Legacy. Grading activities at the Tustin
Legauy, however, may uncover buried archeological resources. |n this case, appropriate mitigation
measures were identified in the Program E|S/E|R for K4CAG'Tuatin and are incorporated herein.
|ofiU developments outside of the Tustin Legacy are located in the urbanized areas of the City. The
City's General Plan does not identify the inhU sites as sensitive areas and there are no known
archeological resources exist in the in0| sites. However, through City's standard procedures and
po|inies, if buried archeological resources are found, certified archeologists would need to be retained NOR
tn assess the site significance and perform appropriate mitigation.
The implementation of Housing Element Update would not result in any |nnpeots beyond those
identified in the Program E|S/E|R for K8CAS'Tustin.

Development anticipated by the housing okamord would be located mostly in the Tustin Legacy.
Grading in the Tustin Legacy may destroy geological deposits within which unique paleontological
resources are buried. In anticipation of possible impacts to resources, e Paleontological Resources
Management Plan (PRMP) has been prepared which would apply to any type of grading/development
activity at the Rouse Plan. The Program EIS/BR for MCAS'Tuotin has incorporated mitigation
moosunom to reduce potential impacts to less than significant |ema!s by requiring certified
paleontologists toberetained to assess the site significance of archeological resources and conduct
salvage excavation of unique paleontological resources, if they are found.
Infill developments would be located in the urbanized areas. The City's General Plan does not identify
the infiU sites as sensitive areas and there are no known paleontological resources exist inthe infiU
sites. However, through City's standard pnnoadunya and po|idee, if buried paleontological resources ON

other substantial evidence of known fault? Refer to Division of NYimms and Geology
Special Publication 42.
ii. Strong seismic ground shaking?
iii. Seismic-related ground failure, including liquefaction?
iv. Landslides?
Geotenhnical hazards that may affect the development ofhousing units within the Rouse Plan area
and |nhU areas are either related to seismic events ornon+seimnnic events. Genbschnico| hazards not
related to earthquake activity include local settlement, regional subsidnnoe, expansive soi(n,
construction-related slope instabiUh/, erosion, landslides, and mudUmws. Seismic hazards include
surface default disp|aoenent, high-intensity ground shoking, and ground failure, ground lurching,
tsunami and seiches, and flooding attributable to dam failure after an earthquake.
According to the City's General P|an, there are semano| unnamed faults within 10 to 45 miles of the
City, mapped by the Division of K4inmo and Geology. The fault with the most potential for activity is
the E| Modena Fault; hnwwver, it and all other faults one considered inactive. The City does not lie

within the bounds of an "Earthquake Fault Zone," as defined by the State of California in the Alquist
PriobEarthquakeFaultZoningAct
There are a number of faults in the southern California area which are considered active and which
could have an effect on the site in the form of moderate to strong ground shaking, should they be the
source of an earthquake. These indude, but are not limited to: the San Andreas Fault, the San
Jacinto fault, the Whittier-Elsinore fault, the Chino fault and the Newport-Inglewood fault zone. The
possibility of ground acceleration or shaking at the site may be considered as approximately similar to
the southern California region as awho|e.
The Newport-Inglewood Fault (about 10 nn||ms southwest of the City) would likely generate the most
severe site ground motions. The Newport- Inglewood Fault would be capable of maximum credible
magnitude of 7.1. Estimated peek horizontal ground accelerations resulting from the above-stated
maximum credible earthquakes on the Newport- Inglewood Fault are on the order of 0.43g. The
duration of strong motion on the Newport- Inglewood Fault would be about 26 seconds fora 7.1
magnitude earthquake and about 11 seconds for a maximum probable earthquake of 5.9 magnitude.
Since any areas in the City would be subject to strong ground shaking during major earthquakes,
similar to other areas in California, any development that occurs would be required by City Ordinance
to comply with auisnnio design parameters contained in the most current version of the Uniform
Building Code for amisrnio zone 4. Title 24 of the California Building Code, and the standards of the
Structural Engineers Association of California. Compliance with these existing building standards is
considered the best possible means of reducing seismic hazards. Tharefore, no significant impacts
are anticipated as a result of implementation of the Housing Element Update.

b) Result in substantial soil erosion or the loss of topsoil?
Developments anticipated by the housing element are nxoaUy located in the Tustin Legooy. The
Program BS/E|R for MCAS-Tustin identified the soils in the Tustin Legacy area as expansive,
unstabka, and subject to erosion. Grading within the Tustin Legacy could result in increased erosion
rohes, especially if grading is conducted in dry, but windy, summer weather. Such activities are
required to comply with existing City regulations related to erosion and runoff control. Once an
individual site in graded and landscaping vegetation is eotmb|inhed, the erosion potential of the soils
would be diminished to o level of insignificance. Therofore, the impact is considered less than
significant.
Infili areas outside the Tustin Legacy are relatively flat and surface runoff would be similarly controlled
by existing City regulations. Future developments would also be required to comply with Best
Management Practices and other City regulations to minimize potential erosion and sedimentation
impacts into City storm drains. In edditinn, development sites are required by City Code to be
improved with landscaping which would reduce the potential for on-site erosion, after construction.
No significant impacts are anticipated.

subsidence, liquefaction orcollapse?
Liquefaction describes a phenomenon in which cyclic otnaeses, produced by earthquake induced
ground rnotion, create excess pore pressures in na|aUve|yoohosion|eas soils. This occurs in areas
where the ground water table ia within 5O feet nf the ground surface. According hz the City's General
Plan, soils in Tustin are more susceptible to liquefaction in the southern portion of the City. The area
north nf the Santa Ana freeway is identified asbeing moderately susceptible. Soils in the foothill
areas are generally not susceptible to liquefaction due to the more solid underlying geologic structure
and lower water table.
The Tustin Legacy located south of the Santa Ana freeway, has a high probability of liquefaction in
the event ofa major earthquake. The Program BS/E|R for K4CAS-Tustin addresses potential impacts
that may result from |iquehao1ion, and mitigation measures were incorporated to reduce the potential
impacts toa level of less than significant. Areas within the Tustin Legacy have also been determined
by the State geologist to be within a liquefaction hazard zone. Compliance with ex/sting Shah* and
local regulations and standards and established engineering procedures and techniques would
provide adequate protection from geo0achnioa| hazards. As a result, the potential impact would be
less than significant.
Similar to the Tustin Legacy, infiU developments outside the Tustin Legacy would also be required to
comply with existing State and local regulations and s(ondords, and the State Department of
Consnrvotion. Mines and Geology Division's established engineering procedures and tenhn|ques, to
identify necessary improvements to ensure long-term geotechnical stability.

the Tustin Legacy lies within on area of high to very high oxponsivityofsoils. |nfiU areas outside the
Tustin Legacy have not been identified as areas with expansive soils.
As part of the City's development revimm, each dovn|opnnerd would be required to provide o
determination of the expansion potential of on-site soils and implement appropriate remedial
measures in accordance with the City's requirements. The measures might include the removal of
clay-rich soils and replacement with specific thickness of non-expansive granular soil beneath the
s(runtunas, concrete s|ebs, and footings. Mixing during grading of localized expansive soils with
granular non-expansive soils could also be used to reduce this hazard. Post-construction drainage
control to keep water from collecting under or adjacent to structures might also be used to reduce the
hazard. Compliance with State and local regulations and etondards, and established engineering
procedures would not result in an unacceptable potential risk of loss, injury, or death. Impacts related
to expansive soils would be less than significant.

a) Generate greenhouse gas omissions, either directly o, indirectly, that may have m significant
impact on the environment?
b) Conflict with an applicable p|an, policy or regulation adopted for the purpose of reducing the
emissions of greenhouse gases? --
New development in accordance with the City's Housing Element Update would create new sources
of greenhouse gas (GHG) emission which could result in significant impact, The Program BS/E|Rfor
MCAS'Tuatin does not specifically provide on analysis of GHG emissions. Howemar, potential
impacts are indirectly addressed, and the development would not result in any impacts beyond those
identified in the Program E|EVE|R for KXCAS'Tuotin.
New development would generate greenhouse gas emissions duo to new vehicle trips, use of
construction equipment, and off-site power and natural gas generation. During the construction
phases of individual development pnojmota, construction vehicles and activities would also generate
emissions. Greenhouse gas emissions associated with the Tustin Legacy project, in addition to infi||
deve|opment, could occur over the short-term for denno|ihon, site preparation, and construction
activities to support the proposed land use. In addition, emissions could result from the |ung-barrn
operation of the completed development. GHG emissions associated with the Housing Element
Update and the development of residential uses within Tustin Legacy would occur over the short term
from construction antivities, consisting primarily of emissions from equipment exhaust. There would
also be long-term regional emissions associated with project-related new vehicular trips and indirect
source emissions, such as electricity usage for lighting.
Future development projects involving temporary increases in greenhouse gas emissions are likely to
occur during construction which would be greater than those typically experienced in the existing
neighborhood. New construction will be required to comply with the latest edition of applicable codes
which include energy codes related to efficiency. Hovvever, impacts associated with any future
project would be identified during the project review process and evaluated in conjunction with the
applicable discretionary or building permit process that may be subject to separate CEC)Arevievv.
The Housing Element Update would not conflict with on applicable p|en, po|ioy, or regulation adopted
for the purpose of reducing the emissions of greenhouse gases and does not differ from the existing

d) Be located on a site which is included on a list of hazardous materials sites compiled
pursuant to Government Code Section 65962.5 and, as a mssu|t, would it create o significant
hazard to the public orthe environment?
The Program E|S/E/R for MCAS-Tustin has identified areas with potential environmental
contamination and debris on the site as a naou|t of military activities. The Department of the Navy
(DON) is in the process of implementing various remedial actions that will remove, manage, or isolate
potentially hazardous substances. This is required by the Federal Law.
Although the development of residential units within the Tustin Legacy would not result or create
significant hazardous aubetonre, recreational uses (commercial, linear parka, oh:.) to support the
residential uses may utilize pesticides. However, through compliance with existing applicable
Fedmra|. State, and local negu|aUons, any potential impacts would be reduced to below level of
significance,
Infill developments would be unlikely to use, transport, or dispose significant hazardous materials due
to their nature as residential properties. Other than those chemicals typically found in residential
properties (i.e. cleaning solutions, #arti|izars, etc. regulated by the Orange County Health Department
if disposed innpropody), no hazard or hazardous materials would likely be tnansported, us*d,

e) Fora project located within an airport land use plan or, where such plan has not been
adopted, within two miles mf a public airport or public use airport, would the project result ina
safety hazard for people residing or working in the project area?
John Wayne Airport is located approximately two miles southwest of the City of Tustin. This facility is
the primary airport serving Orange County. Land use naathohons exist for areas adjacent to and
under flight patterns for John Wayne Airport. These regulations restrict sensitive uses in order to
minimize the potential loss of life and property in the event of an eironeft eocidant, reduce noise
impacts, and reduce the risk ofaircraft colliding with tall buildings or other structures.
The developments anticipated by the Housing Element Update consist of developments in the Tustin
Legacy and infiU areas outside the Tustin Legacy. The aircraft pattern for John Wayne Airport
crosses north of the westerly portion of Tustin and in the vicinity of Rod Hill Avanue, acUeoant to the
Tustin Legacy area. According to Airport Land Use Commission (AELUP), no restrictions are in place
in conjunction with possible ononh zones. However, the Tustin Legacy falls within e 20.000 foot area
of concern for buildings with heights ranging from 110 feet to 200 feet. Any structures within the
Tustin Legacy that exceed the height thresholds would be subject to review by the Federal Aviation
Administration (FAA) and the Airport Land Use Commission.

h) Expose people orstructures hoa significant risk ofloss, injury, or death |nvoh/ingwi|d|and
fires, including vvhone mi|d|ands are adjacent to urbanized areas or where residences are
intermixed with wildlands?
The Orange County Fire Authority (OCFA) identified two major sections of the City—residential and
commercial districts south of the Santa Ana Freeway and north of Edinger Avenue--es having
inherent fire danger problems, which could result in extensive fires under worst-case conditions. This
whole area includes high-density residential development composed of wood frame buildings with
shake shingle roofs. The second area of concern is the Peters Canyon area. This is adjacent to o
wildland interface area from which natural fires could spread to residential neighborhoods.
Urban and wildland fire hazards could result from a number of causes, including arson, carelessness,
home or industrial eooidents, or from ignorance of proper procedures for home or business repairs.
Low water pressures could also contribute tofire hazards in Tustin. The current practice and code
requirements for use of fire retardant roofing noator|a|s, the enforcement of building code that assure
adequate fire prote(tion, the upgrading of emergency water line capacities in conjunction with
development as required by the C}nmngn County Fire Authority, and the City's and Orange County Fire
Authorities maintenance of its mutual aid agreement with surrounding jurisdictions will reduce the risk
of loss, injury, or death from fires.
New development as a result of the Housing Element would be required to comply with the City's and
OCFA rules and regulations. Thus, any impacts would be reduced tou level nfinsignificance.

3.9 HYDROLOGYAND WATER QUALITY
a. Violate any water quality standards or waste discharge requirements?
The Housing Element Update provides for the development of 1,227 housing units. As these units are
deve|oped, wastewater would be discharged into the local sewer system and on-site drainage would
flow into the City's existing storm drain system. As part of Section 402 of the Clean VVatu/ Act. the
U.S. Environmental Protection Agency (EPA) has established regulations under the National Pollution
Discharge Elimination System (NPDES) program to control direct sk/rnn vvahar discharges. In
California, the State Water Quality Control Board (VVCQB) administers the NPDES permitting
program and is responsible for developing NPDES permitting requirements. The NPDES program
regulates industrial pollutant dinoha,Oen, including construction activities. The City of Tustin is o co-

Groundwater resources in the area consist of a complex system of aquifers and aquidudos,
separated by bedrock or layers of soil. The City of Tustin is located within the East Coastal
Plain/Orange County groundwater basin. The City straddles the |rvine. Fonaboy. and Pressure sub-
areas of the Orange County Basin. Within these systems the aquifers are separated by low-
permeability strata known as aquitards, which generally limit the vertical hydraulic exchange between
the aquifers. The Basin is replenished with flows from the Santa Ana River and imported water
supplies purchased from Metropolitan Water District. The Orange County Water District actively and
beneficially manages the Basin.
The development of 1.227 additional housing units by 2021 would increase water consumption in the
City as well as increase dependence on local and imported supplies of groundwater. The Program
E|S/E|R for K4CAS-Tustin discusses impacts related to groundwater supplies and naoherge, and
according to the iRVVD, there is adequate water capacity to supply civilian reuse development at the
former K8CAS-Tustin. As in the infiU areas, the City's Water Department has also determined that
there would ba adequate water supply ho support infi||developments. Therefore, no significant impact
to groundwater supplies or groundwater recharge vvuu|d result from the implementation of the
Housing Element Update.

Erosion is not anticipated to be substantial during construction or operation of developments

and channels are undersized.
To accommodate the development at the Tustin LeQacy, a conceptual storm drain plan has been
developed in coordination with the Orange County Flood Control District(OCFCD). This conceptual
system includes five nna]nr drainage areas with mainline facilities and improvements to the OCFCD

Expose people or structures hue significant risk of loss, injury, or death involving flooding,
including flooding as a result of the failure ofo levee mrdam?
According to the City's Water Dnpedm/ent, catastrophic dam failure or flooding resulting from the
failure of any one of the main reservoirs in the Tustin area could generate flooding impacts in the City
of Tustin. The risk of flooding resulting from dam breaches or failures would be reduced by working
directly with the State DMioe of Emergency Services to make physical improvements (if necessary)
and monitor the safety of the reservoirs.
With respect to the Tustin Legacy area, if either of the Santiago and Villa Park reservoirs failed during
or after a major earthquake, this would cause e flooding impact to the Tustin Legacy area and
potentially toinfi||areas. However, both reservoirs have been designed and constructed according to
applicable earthquake standards to reduce the chance of reservoir failure. The City has also
implemented emergency response plans in the noee of an earthquake to respond to this hazard.
These plans would ensure the nanlove| of people from the site to avoid loss of human |ife, but
property could be exposed. Property loss would be experienced with reservoir fai1ure, but by working
directly with the State Office of Emergency Services to make physical improvements (if necessary)
and through proper monitoring of the aehaty of the nosorvnirs, unacceptable potential risk of loss,

at Tustin Legacy and infiU developments. The |n1p|onlenbadun of the Housing Bement Update would
involve m change in land use from vacant to residential urban uses and/o/ intensification of uses at
curtain sites. The change in land use and/or intensification of uses at m*doin sites however would not
significantly divide any community orreduce access to community amenities. Compliance with the
Land Use Bement of the General Plan and the City's zoning regulations would ensure that the
development of new housing units would not divide an established community.

3. 12 NOISE
a) Exposure of persons to or generation of noise levels in excess of standards established in the
local general plan or noise ordinance, or applicable standards of other agencies?
Noise impacts can be broken down into three categories. The first is "audible" impacts, which refers
to increases in noise level that are perceptible to humans. Audible increases in noise levels generally
refer to e change of three dBA or more since this }eve{ has been found to be barely perceptible in
exterior environments. The second category, "potentially audible," refers too change in noise |ovo|
between one and three dBA. This range of noise |ewa|s was found to be noticeable to sensitive
people in laboratory environments. The last category is changes in noise level of less than one dBA
that are typically "inaudible" to the human ear except under quiet conditions in controlled
environments. Only "audible" changes in noise level are considered as potentially significant.
Mobile-source noise (i.e. vehicles) in preempted from |ooe| regulation. For mobile suuvoua, an impact
would be considered significant if the project were to increase noise by 3 dBA (a barely discernible
increase) and the resultant noise exceeded the City's noise standards, or dBA (notable to most
people) if the resultant noise remained below City standards.
The proposed project site is located within the City of Tustin and thus is subject to the General Plan
and existing City's noise ordinances. The General Plan discusses the effects of noise exposure on
the population and sets land use compatibility goals aimed at protecting residents from undue noise. KI
The Plan follows the recommendations sot forth in Title 25 of the California Administrative Code and
discourages residential development in areas where exterior noise levels exceed 65 dBA CNEL.
unless measures are implemented to reduce noise levels to below this value.

Noise Ordinance
The Tustin Noise Ordinance establishes standards for maximum noise levels within residential
enaan in the City. The exterior noise level standard hsS5dBA. and the interior noise level
standard is 45 dB/\. The City nemUz8n that the control of construction noise is difficult at bcai
It does hmvew*/ implement its Land Use Compatibility Standards, which provide development
standards for exterior noise levels across the various land use categories.
State of Califomia Standards
ME The California Office of Noise Control has set acceptable noise limits for sensitive uses.
Sensitive-type land uses, such es schools and homes. are "normally acceptable" inexterior
noise environments up(oO5 dBACNELand "conditionally acceptable" in areas upto7UdBA
CNEL. A "conditionally acceptable" designation implies that new construction o/development
should be undertaken only after m detailed analysis of the noise reduction requirements for
each land use type in made and needed noise insulation features are incorporated in the
design. By comparison, a "nu,nna||y acceptable" designation indicates that standard
construction can occur with nn special noise reduction requirements.
Future development would be required to comply with the City's Building Code and State's existing
regulations on vehicle noise, roadway construction, and insulation standards. This would ensure that
noise ksvn|s in Tustin residential areas are maintained within a000ptsbky standards that prevent
extensive disturbance, annoyance, ordisruption.
The implementation of the Tustin Legacy would result in additional vehicular noise from traffic
generated by new development. Projected noise levels along major roadways are included in the
Program BS/E|R for IVICAS-Tustin. The proposed extension of Tustin Ranch Road could expose
existing residences to noise levels greater than 65dB(4) CNEL Some existing residential units within
the Tustin Legacy area may experience noise levels greater than 65dB(4) CNEL With reuse and
future development, noise levels at residential and pork locations adjacent to Warner Avenue may
exceed 65dB(\) CNEL. The Program E|S/E|R for K4CAS-Tustin addresses potential impacts that may
result in noise impacts and mitigation measures were incorporated to reduce the potential impacts to
a level of less than significant.
|nfiU developments would generate additional noise typically associated with residential uses to the
area. Howevor, compliance with the City's existing noise regulations would reduce impacts tua |noo
than significant level. Development of any in8|| sites adjacent to arterial noise exceeding the
maximum noise |ema|n vvnu|d be required to comply with State and Building Coda standards for
insulation and interior noise levels.
In summary, the implementation of the Housing Element Update vvouk1 not result in any impacts
beyond those identified in the Program EIS/EIR for IVICAS-Tustin.

cU A substantial temporary or periodic increase in ambient noise levels in the project vicinity
above levels existing without the project?
Noise levels associated with construction onhviUms would be higher than the ambient noise levels in
the City, but would subside once construction of the residential units proposed in the Housing
Element Update are completed.
Two types of noise impacts could occur during the construction phase, First the transport ofworkers
and equipment hothe construction site would incrementally increase noise levels along site access
roadways. Even though there would be a relatively high single event noise exposure potential with
passing trucks (a maximum noise level of 86 dBA at 50 feet), the increase in noise would be less than
one dBA when averaged over 24-hour period and should therefore have a |ons than significant
impact at noise receptors along City truck routes.
The second type of impact is related to noise generated by on-site construction operations, Local
residents would be subject to elevated noise levels due to the operation of on-site construction
equipment. Construction activities are carried out in dieonnha xteps, each of with its own mix of
equipment and consequently its own noise characteristics. Table 1 lists typical construction
equipment noise levels recommended for noise impact assessment at a distance of 50 feet.
Noise ranges have been hound to be similar during all phases of construction, although the erection
phase tends bobe less noisy. Noise levels range upho8B dBA ot5O feet during the erection phase of
oonsiruction, which is approximately dBA lower than other construction phases. The grading and
site preparation phase tends to create the highest noise |ewa|n. because the noisiest construction
equipment is found in the earthnloving equipment category, This category includes excavating
machinery (backfi||ers, bu||dozers, drag|inms. front |oadern, etc.) and merthnnoving and compacting
equipment (compactors, scrapers, graders, etc). Typical operating cycles may involve one or two
minutes of full power operation followed by three to four minutes at lower power settings. Noise
levels ot50 feet from earthrnoving equipment range from 73toQ8dBA,

3.13 POPULATION AND HOUSING
a) induce substantial population growth in an area, either directly (for example, by proposing
new homes and businesses) or indirectly (for example, through extension of roads or other
The City of Tustin had an estimated population of 76,567 in 2012. The City has experienced rapid
population growth over the last 30years. This population growth has occurred with increases in the
number ofhousing units. The Housing Element Update anticipates an additional 1.227 housing unibs,
including single-family residential and rnuhi'harni|y residential, for development through 2021. The
anticipated units are within the constraints set forth in the City's current General Plan.
The development of an additional 1,227 housing units, of which the majority would be located at the
Tustin Legacy, would result in an increase in the City's population and housing over eneight-year
period, not a significant impact on the City's population. The development of the Tustin Legacy would
also result in the development of affordable housing in selected areas which would address the needs
of the homeless, as well aa those of low and moderate income. Therefore, the implementation ofthe
Tustin Legacy would provide o beneficial impact.
|nfiU developments that would occur outside the Tustin Legacy area would also generate population
and housing growth in the City. However, this growth is insignificant given the City's h»bs| population
and if is within the constraints set forth in the City's General Plan. This will help the City to achieve its

Future developments anticipated by the Housing Element Update would be constructed primarily on
vacant land in the City. There may be new in0| construction activities that could result in the
displacement of existing housing units, however there is no requirement in p|000 that requires the
construction of replacement housing elsewhere. Consistent with EVa0a Law. the C|h/ would not be
required to prepare relocation and/or displacement p|ana, replace units displaced or dusbnymd, or
provide relocation services and benefits to displaced households.

3.14 PUBLIC SERVICES
Would the project result in substantial adverse physical impacts associated with the provision
of new or physically altered governmental facilities, need for new or physically altered
governmental faui|ithms, the construction of which could cause significant environmental
innpacts, in order to maintain acceptable service natios, response times or other performance
objectives for any of the public services:
a) Fire protection?
The City ofTustin contracts with the Orange County Fire Authority (OCFA) for fire protection services.
The Fire Authority maintains three stations in the City.
New housing developments would increase demand for fire protection, as well as emergency medical
services. Individual development projects would be required to meet existing UCFA regulations
regarding construction matodo|e and nlethoda, emergency eomans, water mains, fine #ow, fine
hydrants, sprinkler syntorns, building setbaohn, and other relevant regulations. Adherence to the
OCFA regulations would reduce the risk of uncontrollable fire and increase the ability to efficiently
provide fire protection services to the City. The number offire stations in the areas surrounding the
site will meet the demands created by the proposed project,
b) Police protection?
The City of Tustin operates its own Police Department. Now housing developments at the Tustin
Legacy would increase the need for police emergency and protection services. The need for police
protection services is assessed on the basis of resident population estinnahan, square footage of
industrial uaes, and square footage of retail uses. The Program E|S/E|R for MCAS-Tustin identifies
that the need for additional police services could bo accommodated at the existing City police station
--
and no new facilities would be required.

c) Schools?
Development of additional housing would induce population growth, therefore increasing the number
of school age children. Df the 1.227 housing units proposed in the Housing Element Update, most
housing developments anticipated would be located in the Tustin Legacy.
The Tustin Legacy is located within the Tustin Unified School District(TUSO). Irvine Unified Bohno|
Oisthot(|UGO). and Santa Ana Unified School Oisthot(8AUBD). The implementation of the Tustin
Legacy would provide for two 10-acre elementary school sites and one 40-acre high school site within
the TUSD. The TUGD has agreed that these sites would be considered adequate to mcoornrnoUehs
now students generated by the Tustin Legacy dove|opment, as well as some of the future growth
anticipated for the Tustin community asowhole. With respect ho the |USD. the implementation ofthe
Tustin Legacy would provide for o 20-enna school site to |UGD to serve the growing Studunt
population within its district. With respect to the SAU3D, although no housing exists in this area to be
reused and no new housing would be constructed in its boundorima, indirectly new students could be
generated through the provision of new employment. The commercial uses would generate
employment and if new employees were to seek housing in locations served by the 8AU8U, they
would indirectly generate students. However, where these students would locate within SAUSD is not
known at this time, and accordingly, construction or housing impacts cannot be identified. There isno
impact on community college facilities because students in Tustin can attend any community college
in the County. Thenefone, except for construction level impacts which will be mitigated to e level of
insignificance due to required compliance with existing City regulations, no other school impacts are
anticipated.
With respect to the in5|| areas, all potential sites are located within the TUSD boundaries. Futuna
anticipated growth forth* anticipated infi|| sites will be assessed school impact fees to ooromnnodaho
any impacts to existing schools.
d) Parks?
The City of Tustin currently has 14 parks and 4 community/recreation facilities. The implementation of
BE
the Tustin Legacy would provide new perk sites. These park sites include a regional park, n
community park, and several smaller neighborhood parks. A linear park would be constructed as
vvo||. Those facilities would provide park and recreation opportunities to the population of the Tustin
Legacy areas as well as the City and the region and their development will not result in o significant
impact on the environment. Once uonatruoted, these perks would meet residential population
demand. Existing parks in the City of Tustin will serve new infill development as well.
a) Other public facilities?
Most of the development of these new housing units would be provided within the Tustin Legacy.
The Program E|8/E|Rfor K4CAS-Tustin discusses impacts na|ahad to other public facilities that may
result from the implementation of the Tustin Legacy. These facilities include libraries and recreational
bikeway/trails.
Library
Using the County's criteria, the implementation of the Tustin Legacy would result in a demand of up to
approximately 2.500 square feet of library apoma. This relatively omoU amount of space is well below
the library system's general nnininnunn size of 10'000 square feed for e branch |ibnmry, and would not
trigger the need for e new facility. Thooefbro, there would be no significant effects on the
environment. Noverthm|ess, a new library twice the capacity of the previous library was completed in
200Qho accommodate existing and future Tustin residents.
Recreational Bikeway/Trails
Implementation of the Tustin Legacy would include bikeway/riding and hiking haUa, although such is
not required by the Housing Element Update. This system would connect vital links necessary for a
comprehensive regional and improved local bikeway/riding and hiking trail ayshynn and would be u 110�
beneficial impact. --

ad Would the project increase the use of existing neighborhood and regional parks or other
recreational fad|hies, such that substantial physical deterioration of the facility vvmu!d occur
orboaccelerated?
The City of Tustin has 16 parks and recreation facilities on approximately 100 acres and, through the
school district, operates school playgrounds. In addition, the City maintains one senior citizen nonhar
and three henni/y and youth community centers. The implementation of the Tustin Legacy vvouk]
provide new park sites to serve residents generated under the Housing Element Update. There isno
evidence that the |nfiU development or Housing Element Update will cause or accelerate the physical
deterioration ofparks.

b) Does the project include recreational facilities or require the construction or expansion of
recreational facilities, which might have anadverse physical effect onthe environment?
New development anticipated by the Housing Element Update would increase the demand for parks
and recreation facilities in the City. The implementation of the Tustin Legacy would provide new park
sites. Those perk sites include approximately 296 acres of public and private parkland which
comprises of 202 acres of public parks and nsnnsatione| areas (including the 84.5 acres of Urban
Regional Park). Since sufficient park/and is provided within Tustin Legaoy, development of new
housing unite vvnu|d not generate an increase in the use of existing off-site parks and reonaebono|
facilities. However, the development of these facilities will result in construction level impacts that can
be mitigated to a level of insignificance under existing City regulations.
|nfiU developments would likely utilize the City's existing recreational facilities. Thenuh)re, no
significant impact would result from the development ofinhUareas.

a) Cause an increase in traffic, which is substantial in relation to the existing traffic load and
capacity of the street system (i.e. result in a substantial increase in either the number of
vehicle trips, the volume to umpuudy ratio on noods, or congestion at intersections)?
The Housing Element Update provides for the development of 1.227 housing units required by the
Regional Housing Needs Assessment (RHNA). This development would be located in the Tustin
Legacy and at infi|| sites. The odditional development and associated traffic volumes of developing
the Tustin Legacy are included in the traffic analysis portion of the Program EIS/EIR for MCAS-Tustin.
As the innpootu of traffic due to housing alone were not separated out and ana|yzad, the following
discussion includes impacts due tocommercial, industrie!, and institutional usea, as well as housing.
In genena|, o number of intersections would be significantly impacted at the build out of the Tustin
Legacy. Most of these impacted can be mitigated to e |ewa| of less than significant. However,
significant (rehiu impacts would remain at the intersections of Tustin Ranch Road and Walnut
Avenue, and Jamboree Road and Barranca Parkway until full build-out (year 2020).
(nfiU areas are located within the established street system. Although traffic in the City ofTustin is
within the acceptable level of service standard, there are intersections that are at an unacceptable
level of service. Through the City's existing Design Review process, developments that contribute 1
percent or more of traffic will be assessed with mitigation fees, in areas with an unacceptable level of
service, as part nf the City's Capital Improvement Program. |n addition, where applicable, the City
would require dedication of right-of-ways and/or require developers to construct the needed
improvements to improve the level ofservice. Therefore, compliance with the existing City's
regulations would reduce potential traffic impacts to a level that is less than significant.
In summary, the implementation of the Housing Element Updaba, particularly the development at the
Tustin Legacy and infiU |ocahons, would potentially result in immitigable impacts at two intersections
described above. Howew»r, the implementation of the Housing Element Update would not result in
any impacts beyond those identified in the Program EIS/EIR for MCAS-Tustin.
Mitigation Measures/Monitoring Required: A Statement of Overriding Considerations was adopted
by the City Council. No further mitigation measures would be required beyond those identified in the
Program E|S/E|R for K4CAS-Tustin. No mitigation measures are necessary for infi|| developments.

b) Exceed, either individually or cumulatively, u level of service standard established by the
county congestion management agency for designated roads orhighways?
The City's Circulation Bonnant establishes o standard fora Level of Service (LOS) ^C^ or better for
major intersections in the City; the City considers LOS "A" through "C" as acceptable, and LOS "D" or
greater as unacceptable. The County's Congestion Management Plan (CK4P) indicates the LOS
should be LOS ''E^ or better for CK8P roadways (freeways and major highways).
Development anticipated by the Housing Element Update would be provided in Tustin Legacy and at
|nfi|| land. The Program E|S/EiR for K8CAS-Tustin provides traffic impact analysis and mitigation
measures to address the naquinsnnonta of the Growth Management Plan and the Congestion
Management Plan to reduce the |rnpeo\s to a level of insignificance. In gonera|, e number of
intersections would be significantly impacted at the build out of the Tustin Legacy. Most of these
impacted can be mitigated to a level of less than significant. Hovvever, significant traffic impacts
would remain at the intersections of Tustin Ranch Rood and Walnut Avenue. and Jamboree Road
and Barranca Parkway under full build out (year 2O2O).

g) Conflict with adopted po|icins, plans, or programs supporting alternative transportation (e.g.
bus turnouts, bicycle racks)?
City of Tustin residents have access to several forms of alternative transportation such as the
K4e\no|ink, busus, and bicycle paths. The development of 1.227 housing unity may create additional
demand for bus service. At the same \inne, the now arterial roadways proposed through the Tustin
Legacy area would provide opportunities for future bus routing, serving persons residing and working
in the Tustin Legacy area. The new routes would provide improved service with more direct routes
for riders not associated with the Tustin Legacy. The Orange County Transportation Agency (OCTA)
prepares regular updates of the countywide transit system. Bus stops would be included in the
updates and would be accommodated as development occurs. In eddition, a commuter rail station
located at the corner of Jenobnvao Rood and Edinger Avenue provides transit opportunities to
residents and workers.
The Tustin Legacy also identifies additions to the bikeway system, providing additional segments and
greater connectivity. The added bike trails would provide an overall benefit to the County bike trail
eysbann. |nfi|| developments would be located in the established ensa, and it would be unlikely to
conflict with adopted policies, plans, or programs supporting alternative transportation.

Wastewater originating from the proposed new housing units would be treated by facilities owned by
the Irvine Ranch Water District (|RVVO) and/or the Orange County Sanitation District (OCSO). |RVVD
and DCSO provide sewage treatment service to the City of Tustin. Sewage from the City is diverted
to Reclamation Plant Number 1 located in the City nfFountain Valley,
For the Tustin Legacy, the Program E|G/E|R for MCAG-Tustin indicates that implementation of the
Tustin Legacy will cause additional demand on the existing sewer system from increased sewage

c) Require or result in the construction of new water or wastewater beatn)ont facilities or
expansion of existing fmni|itiea, the construction of which could cause significant
environmental effects?
Increased water consumption would result in o higher demand for water resources. Most housing
developments under the Housing E|envanL Update would occur within the Tustin Legacy. The Tustin
Legacy is located within the water service jurisdiction of the }nine Water Ranch Districts (|RVVD).
The |RVVD imports approximately 27 percent of its water via Metropolitan Water District (MVVD) and
48 percent nf the overall supply is pumped from local wells. Df the remaining 25 percent, 21 percent
comes from capturing, treating and reusing water that would otherwise go out to sea for irrigation and
other non-potable uses and 4% comes from other sources. |RVVD has indicated that they would be
able to provide water services to the project area and thus the impact would be less than significant.
|nfiU projects would be served by existing systems owned and operated by the City of Tustin and
Reclaimed water for non-domestic uses such as for agriculture and landscape irrigation is treated at
the district's Michelson Reclamation Phyrd and used an reclaimed water. Potable Water supply is
purchased by the |RVVO and the City ofTustin from the WiVVO distribution system or pumped from
local wells.
Sewer lines in Tustin are owned and maintained by the Orange County Sanitation District (OCSD)
and |RVVD. With the implementation of development in the former MCAS-Tustin. Tustin LeQauy, e
new water and sanitary sewer system would be necessary. The only impacts would be construction
level; these impacts would be mitigated to a level of insignificance by existing City regulations to
reduce construction impacts. With respect to the infiU orean, replacement of existing facilities with
new residential units would not create the need for a new water or wastewater facility.

d) Require or result in the construction of new storm water drainage facilities or expansion of
existing foci|ides, the construction of which could cause significant environmental effects?
Storm drainage is provided through reinforced concrete pipes and open channels throughout the City.
Storm water flows are directed towards Orange County Flood Control open channels or indirectly to
the Santa /\no River. Shzrnn vvoher in the City generally flows in a general southwesterly direction
towards the Pacific Ocean. The City maintains on NPOES co-permit with Orange County for storm
drain facilities serving Tustin.
New development in the Tustin Legacy would require improvement to the existing ahxnn drain
system. A conceptual storm drain plan has been developed in coordination with the Orange County
Flood Control District (DCFCD). The improvement would include five major drainage areas with
mainline facilities and improvements to the OCFCD Barrenoa Channel. New retention basins would
also be incorporated to handle storm Unwe from the Linear Perk of the Tustin Legacy. Other on-site
facilities would discharge into the County's existing regional facilities. Construction level impacts
would be mitigated to o level ofinsignificance by existing City regulations to reduce construction
impacts.
With respect to the infiU greas, replacement of existing facilities with new residential units would not
cromha the need for a new water or wastewater facility. New development in the infi|| areas would
utilize existing storm drain lines. Compliance with NPDES requirements through the development

reduce the habitat of fish or wildlife spndom, cause o fish or wildlife population to drop
below self-sustaining |ove/s, threaten to eliminate a plant or animal community, reduce the
number or restrict the range of rono or endangered plant or animal or eliminate important
examples of the major periods of California history or prehistory?
b) Does the project have impacts that are individually |imnited, but cumulatively considerable?
("Cumulatively considerable" means that the incremental effects of project are considerable
when viewed in connection with the effects of past projmots, the effects of other current
projects, and the effects of probable future projects.)
o) Does the project have environmental effects, which will cause substantial adverse effects on
human beings. either directly orindirectly?
The adoption of the Housing Element Update would not cause negative impacts. However the
implementation of the Tustin Legacy could cause significant impacts to the environment. These
impacts are identified in the PnoQnann E|S/E|R fnrWCAS-Tustin. Supp|ennent, and its Addenda, and
there are no additional impacts that would be created. On January 16. 2001. the City Council
considered the benefits of the General Plan Amendment incorporating the Tustin Legacy and
be|unmad those benefits against the unavoidable effects related to aeathoUos, cultural, and
paleontological nesoumos, agricultural rmeoumoa, tnafUc/oimu|etion, and air quality, A Statement of
