A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
TUSTIN, CALIFORNIA, CERTIFYING THE FINAL
ENVIRONMENTAL IMPACT REPORT/ENVIRONMENTAL
IMPACT STATEMENT FOR THE REUSE AND DISPOSAL
OF THE MCAS-TUSTIN AS COMPLETE AND ADEQUATE
FOR THE HOUSING ELEMENT UPDATE PURSUANT TO
THE CALIFORNIA ENVIRONMENTAL QUALITY ACT.
The City Council of the City of Tustin does hereby resolve as follows:
I. The City Council finds and determines as follows:
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 described 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); and
Marine Corps Air Station (MCAS) Tustin has been determined surplus to the
needs of the Federal govemment and has been approved for disposal by the
United States Department of the Navy (DON) in accordance with the Defense
Base Closure and Realignment Act (DBCRA) of 1990 (10 USC 2687) and the
pertinent base closure and realignment decisions of the Defense Base
Closure and Realignment Commission approved by the President and
accepted by Congress in 1991, 1993, and 1995; and,
The City of Tustin has been approved by the Department of Defense as the
Local Redevelopment Authority (LRA) for MCAS Tustin and is responsible for
preparing a Reuse Plan describing the reuse of the installation and providing
recommendations to the DON for disposal of the former base to various
public agencies and the homeless. The goal of base disposal and reuse is
economic redevelopment and job creation to help replace the economic
stimulus previously provided by the military installation. The LRA submitted
the Reuse Plan for MCAS Tustin to the Department of Defense in October
1996 and an Errata amending the Reuse Plan in September 1998; and,
On January 16, 2001, the Tustin City Council certified the Joint Final
Environmental Impact Statement/Environmental Impact Report (EIS/EIR) for
the Disposal and Reuse of the Marine Corps Air Station (MCAS) Tustin (the
Program EIS/EIR for MCAS-Tustin). The United States Navy issued a
Record of Decision on the Program EIS/EIR in March 2001. The MCAS
Tustin examined in the Program EIS/EIR was 1606 acres; and,

1. Background
This Initial Study has been pr~ared to evaluate the polential environmental effects associated with the adoption of
:he Cit'}' (>f 'rus:in Housing Element L'pdate (Housing Element Update). This is a revision ro the Housing Eiement
that is required every five (5) >,ears by Government Code Section 65588 (b). TI,As a,nalysis has been conducted in
compliance with the California Envfforanenlal Qualit-}' Act (CEQA) and Guidelines, as amended.
~o ~ PROJ£CT LOCA T/ON
The Regional Location Map (Figure 1) shows the location of tile City of Ius:in within ta~e coniext of the Orange
Count)' region. Tustm is located in Central Orange Count>' and is bordered by a dereloped unincorporated por~on
of Orange Coun.n.' (North Tustin) :o the nortk, tire O:v of Orange to the northwest, Santa .4.ne to the west and
southwest, lr~ine to the south, souti~east, and east. 'Fnc 55 Freeway forms lile majority o!' th',' City's western
boundary, ~e I < wan_sects the southwestern area of the Cfi)', and the Eastern Transpo.,':afio~ corridor para~Lh the
Ci~"s eastern border.
~.2 ENVIRONMENTAL SETTING
1.2.1 Existing La,d
-Fne Cfi)' of Tustin is dereioped with a .mix of cormnerciai, industrial, and residential uses. -l'he growth Wends in
'l-usrin show significant population increases in the 195(.'s, followed by a slower rate of [n-o~'th in the !990s. From
!980 to 1990, ~l~e City's p(>pulation increase,5 fi'om 36, i 19 to 50,689 (.40.3 percent.). Curren~ population estimates
indicate a popu!ati{)n increase of i6.-.64 persons since 1990, representing an increase of 32.5 percent. In !99¢, the
City's estimated popu!a~ion of 67,1-~3 represented 2.,I percent of:he County's total population.
'r!:e Cal:~brn~a Depam'-r:tnt of Finance (DOF) est/mated that in January 2000, 2x.861 homes ours:ed :n Tustin, and
the average househoid size was 2.94 persons. Based on data derived from the National Dezision Systems, ':6
percent of owner-ozcupied units in the City are vaiued at $200,000 or higher. The median ralue for 12ne owner-
occupied units ".s $2-2.970, whick is b. igher than the Count>' as a whole, where ti~c median vahe is S266.T'2.
Overall, the :ned:an resak~ home prices for zip codes m the C/ty of Tustin ranged from $210,000 to $386,000.
According to l{ca!i:ac:s .'a database publisher specializing in tile housing mark:2:), thc average rent fo:' the CiLv of
'Pus:in was 51,067 in March 2000. Tustin :ms a high per:enrage of mul:i-fam/ly uni:s compared
Coun',y con'~"n, unities. Approxi.mately 31.-~ per:erin or'the housing stock is comprised of sing!e-ian~.ily detach:d
~'.'"~ilc 6S.5 per'cern of the housing stock consists of a':.ached and ;:~u!:i-hmily units :vith five er more ','nits.
Additionally, Tustin has a proportionally higher amount of renters than o~,,u]ers. In 1999.41 percent of the housing
stork was ov,,-ner-occupied and 59 pe','cem was renter-occupied.
..'~c:ordi::g ;o Table H-7 of the itoush:g E]emem Update, 936.32 acres of vacant land exist in the Cdt}' of 7ustin,
whi~e anotker 11.42 acres of land are ,and:t-utilized. Based on land use densities, d~is offers a potential for 29,575
to:al housing u:iu on these propemes at. buildout capacity. Of the 936.32 acres of vacant land. 389.2 acres are
located at the ibrn::r MC:\S-Tus~in, 539 acr:s are located in the East Tustiu Specific P;an areas, and: ,~.~ 2 aJes are
ioca:ed g':nera[iy in infill neighborhoods. Tl:e [!.42 acres o!' undcru:iiized land are !ocated ge~:era~iy in '&~ Old
'ro~vn area.
The Ciw' of Tust!:: is required, per Caiigamia Housing Element law, '~o meet its "fa:r share" of existing and fu'.ure
housing needs for all income groups. As determined b,x' the Southern California Association of Governrne:~t
(SCAG), Tustin's "fair si:are" is 3,298 ad'Jifi~nai un,ts far :he 2000-2005 planning period. Based on the analysis c. 5

Existing land uses and activities at the MCAS-Tustin prior to closure offne base are described in the Masterp!an
Marine Corps Air Station Tusthn (DON 19893. The single largest !and use category in the. Masterpian was
an'field operations. The next largest category was agricultural uses. On January 16, 200!. the City Council
adopted a General Plan Amendrc. ent to change the C:t)"s land use designation for MCAS-Tust/n from Military
and Public Institutional to MCAS Tustin Specific Plan. The Specific Plan area is generally bounded by Edinger

City (Figure 1 of the Housing E!emem Up,ate).
Circumstances surrounding the implem,ntation of the Housing F. lemant Up~a;e at thc MCAS-Tustin and in the i~11
sites are essentially the same. In general, these similar circumstances ca'. be summarized as follows:
· Housing units at MCAS-Tustin would be developed in an urban setting involving mixed land uses, similar to
infill development in other areas of the CID,;
· Development of housing umts in at MCAS-Tustin and infill sites w/Il be required to zomply with the same
City's and State's existing regulations pe.naining to air quality, noise, water quahty, consumzfion standards, etc.
· Both MCAS-Tustin areas and infili sites will be served by the same utiliu' providers and x~'i~; utihze the same
utility system;
· '.qoth MCAS-Tus:in areas and ~nfill sites will b: sen'ed by the same public service agencies suzh as Orange

The CiD, is locatsd in a mature area w!th a ..-mx of land uses. The s'arr, ounding citiss of Santa Ann, Orangs, and

PROJECT DESCRIPTION
1.3, I Proposed Land Use
T'ne Housing Elsmen: 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. State Law requires thai the Housing Element consist of"an
identification and analysis of ex/sting and projected housing needs and a sra:emem of goals, policies, quantified
objectives, and sckeduled programs for the prese~'ation, improvement and development of housing." 'i-r.e
residential character of the CiD' is, to a large extent, determined by the varie.'5.' of its housing stock, its location and
r>hvsical zonal:itoh. 'l-ne Housing Element is, therefore, an official municipal response to the need to provide
housing for all economic segments of'he population.
The CiD' of Tustin's Genera; Plan Housing Element and this Hous!ng Eiemem Update detail the Ci%"s five-year
strategy ibc enhancing and preserving ',he con'~munity's character, sets for`h strategies for expanding housing
opporttmities fi)r tine City's various econom/:s segments, and provides the prima.,5..' policy guidance for local
decision-making related to housing. The Housing Element Update provides the implementation strategies for
adJressing the housing needs of'Fustin residents through thc 2000-2005 pla:mlng period.
As described in Section 1.2.1. ninety (90) percent of file housing units required by the Housing Element Update
would be provided at the MCAS-Tustin. Other units woul5 be ,rovided through scaaered infi!', deveiopments
within the City. As a result, the imtia] study prepared for the Housing Element Update focuses primarily on the
MCAS-Tustin Specific Plan area. This is because the circumstances of the .MCAS-Tus~m project sradied in the
Program E1S.'EIR and the Housing Elmn:n: Update project are essentially ',.he same. The Final E:S.~IK for the
Disposal and Reuse of MC:\S-Tustin is a Program EIS E!R/'or MCAS-'l'ustin that was car:if:ed by tile City Council
on January !6, 2001 (here/n after referred to as Program EIS.'EIR for MCAS-T'.:stin). 'i-ne Program EIS,"EiR for
_MCAS-Tustin discusses impacts related to the implementation of the Specific Plan and is incorporated in the initial
study by ',his reference. A cop>' of t~e Program EIS E!R for MC.-\s-'rustin is available for public review at the City
of Tustm Community Rcd:,,'e!opmen: Ag:ney located at 30() C'_'ntennizl Way. Tustin, California 92780.
T.,~e Housing Element Update ~rovides in-depth anaiysis of file City's population, economic, householct, and
household stock characteristics as required by State Law. 'l-ne Element also provides a comprehensive evaluation of
programs a~d regulations related to priority goals, objectives, and pro,am actions that directly address the needs of
'l'usrin residents.
-l-he Housing Element Updale is only one faze: of the City's overall plann!ng progranz The California Oovernmen;
Code requires cleat General Plans contain an integrated, consistent set of goals and policies. ]'he Housing Eiemen:
is, therefore, affected by dsveiopment policies r. ontained ii: off:er elements of the General Pian.

1.3. 3 l'ur£ose of Initial Stud. I,
As discussed in the project location, mos:. of the development of new housing units would take place at the former
MCAS-Tusrin. The purpose of the initial study is to determine whether the Program EIS;EIR for MCAS-Tustin
would adequately descr/be the project's general environmental setting, s/gn:ficant environments! imvacts. ~roiect
ahematives, and mitigauon measures related to each siffnifican*, irrmact. TSe initial study is a!so designed to
determine whether tkere ar~' any additional, reasonable altemauves or w/r/gat/on mess'ares that should be comidered
as ways of avoiding or reducing the project's significant effects.
The CiD' of Tustin is close to i,.s build-out capacity. Oppo."tunkies to meet its "fair share" to build additional 3.298
housing units in the CiD' largely depend on the availability of the former MCAS-Tustir. land. ]--his lm~d is the only
significant area of racom and underuti!ized land that is available in the City to accommodate a large number of
housing units. Other vacant !and identified ir, the East Tustin area are relatively built out since almost a!i
enr/tL*mems in accordance to the East Tustin Specific Plan have been granted and the project is currently ','.nder its
final cans~uction stage.
The Program EIS.'EIR for MCAS-'l'ustin identified several impact categories where significant impacts to the
enviroranent could not be mr/gated to an insignificant ievei, and a:cordingly a Statement o£ Overriding
Cons!derations was adopted by the Cit-v of Tustin for approval of t!',e General Plan Amendment on January 16, 2001.
For the pu~cse of this initial study, an evaluation has been rnaSe to ensure that i:neacrs ere;ious;y identified
reiatir, g ~.e this pro.dec', have not been intensified. M:tigation measures identi~ed in the Pregram EiS EIR for MCAS-
'Yus;in to minim/ze the imoacl that would be appiicab;e to this prr~ect have been ident/5=d.
The }heston', EIS.'IilR ibr NICAS-'rusri:: also id:nt:fied several impact categories wEere im?.ac:s could be lessened
to a level of insignificance w!th the imposition of mitigation measures. Each of these impact categories was
anaSyzed to determine ff new impacts associated with the project would occur tko: were no: identilSed 'in the
Progmm SIS EIK.
lnipact categories not identified to have a potemial :mpact in the Program EIS EiR for MC..\S-Tu_s:in have l:een
reviewed and identified in :he initial smd>' to de:ermine if the project would create any adriinonal or new significant
my'acts which were no: considered by the Pre,am EIS E1R for MCAS-Tustin.

receptors to poliutanrs, based on a project-spectfic screemng analysis).
All answers take account of'fl~e whole action involved, including off-site and on-site, cumulative and project-level: indirect and direct,
and construction and operational impacts.
Once the lead agency has determined that a pan. Scalar physica! impact ina)' occur, then the checklist answers must indicate whether the
impact is potentialiy significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" :s
appropriate if,.here is substantial evidence that ar, effect may be significant. If there are one or more "Po'.~ntially Significant Impact"
enu'ies when the determination is made, an ELK is reqmred. In this case, the Program EIS/EIR for MCAS-Tustin has been reviewed to
determine ifS: is adequate ~br this vroiect.
Earlier analyses may be used for subsequent activities if the effects of the project have been adequately analyzed in a program EIR. in

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?
Dex'elopmenl anticipated by the Housing Element Update would be located in mostly urbanized areas or areas
tk. at are plam~ed to be urbanized that are not part of scenic vistas. No scenic vistas are ioca:ed in the vicinit.v of
any proposed development locations, such as Old Town infill developments, In_fill developments identified in
Table H-6A and Figure 1 o£ the Housing Element Update, and potential resident/al development at the former
MCAS-Tustin. Further, the C~ty of'fusfin does not comain any City- or Coun.'?designated scenic kighways.

'Fne implementation of tile Housing Element Update consists of deveiovment within MCAS-Tustin and infill
areas outside the MCAS-Tustin.
Impacts associated w~th Biological Resources within the MCAS-Tustin area would occur at the construction
phase for implemenung the Reuse Plan development. In general, impacts can be summarized as follows:
Vegetation
Vegetation in t!:e Reuse Plan can generally be categorized as cukivated fields or non-native grassland.
T'n. ere are oniy individual remnants of native pian: s¢ccies. Tko agricultural field on the Air Station are
regularly cultivated with row crops. Because cf the agricr-.ltura! and historic military uses, Cae cultivated
fields and iandscaped areas do nor provide suitable habitat for rare plan: species known from the region.
As such ~:o mnigatior, measure related to vegetation is necessary.
Wildii£e. Sensitive, Threatened, and Endangered Wildlife Species
Agricuh'.-'.ra!, residential, and industrial hnd uses surrounding the MCAS-Tustin and other vacant land area
t?pically would limit a site's value as wildlife habitat. The Program EIS..'EIR for MCAS-Tustin identified
Southwester:: Pon,d Turtle, "species of specia~ concern," within the M CAS bounda~,; however, based upon
the ana'.,ysis in the Program E1S.'EIR, the sighting was found with!n areas identified for development of
comn:ercia~ and conu'nercial businesses. Therefore, no impact to southwestern pond turtle habitat woukl
result f:'om the ~mpiem:nta:ion of the Housing Element Update at the MCAS-Tusdn.

The deveiopment of housing ;units within the MCAS-Tustin Reuse Plan wouid have impacts to wetlands. The
Reuse Plan is situated in ~e 'fustin Plain, which is underlain Icy the lrvlne ~oundwater basin. The site is
situated in historic .'mrshland which was filled over 60 years ago for cultivation. The Peters Canyon Cham~el,
an unlined drainage channel, traverses the MCAS-Tustin area. Based on the '.999 deterrmna:ion, the Reuse
Plan contains and estimated to:al of 29.0 acres of jurisdictional waters. Approxima.:ely 12.8 acres of
jurisdictional waters would be indirectly impacted by charmel improvements l:y Orange Count3.' Flood Conta'ol
District (OCFCD). Another 16.2 acres of jurisdictional waters, of which 2.4 acres are classified as vegetated or
seasonal wetlands would be directly' impacted. The Program EIS/E[R for MCAS-Tus':in has idenvffied
mitigation measures to reduce impacts associated with ju:'isdictional waters and wetlands to a level of

According to ~e City's General Plan, there arc several rumamed faults within 10 to 45 miles of the Cl~',
mapped by the Division of Mines and Geo:,ogy. 'E'~e fau:.r with the most potential for activi.'y is the E1 .Moriena

"Earthouake Fault Zone," as defined bv tile State of California in the Alquist-Prioio Ear*,hquake Fault Zoning
Act.
There arc a number of faults in the southern Californ.ia area which are considered active and which could have
an effect on the site in the form of moderate to strong ~ound shaking, should they be the source of an
earthouake. These include, but are not limited to: the San Anfireas fault, the San Jacinto fault, the Whiuier-
Elsmore hult, the C'.uno huh an,-'- the Ne~.'pert-ingi.'nwood fault zone. The possibili'..y of ground acceleration or
she 'ldng at f.:'.e site may be considered as approximately similar to the somhem California region as a who~e.
The NewporMnglewood Fault (about 10 m/les souihwest o'~'th~ City) would likely generate the most severe site
ground motions. Tke Nex~.?orl-inglewoor/Fault would be capable of a maximum credible magnitude of 7. i.
Estimated peak horizontal grouncl accelerations resulrlng from the above-stated maximum credible earthcuakes
on du~ Ne~,-pon-Ingictvood Fault are on the order of 0.43g. The duration of swong motion on the Ne~o.~-

Since an)' areas in the City would be subject to strong gTound shaking during maior earthquakes, similar to

Liquefagtion describes a phenomenon in whigh cyclic stresses, produced by ea~hqaake induced ground motion,
create excess pore pressures in reia:ively cohesionless soils. This occurs in areas where the ground water table
is within 50 feet of the ground surface. According to the City's General P~an, soils in 'l-ustin are more
susceptible to liouefac:ion Ln tlne southern portion of the Ci~'. The area north of the _-freeway is identified as
being moderately susceptible. Soils in the footh/ll areas are generally not susceptible te lic~uefa:,tion due to the
more solid underlying geologic sn'ucture and lower waler table.

Inundation by seiche, tsunami, or mudflow?
A seiche is a surface ways created when a body of wmer su:h as a lake or reservoir is skaken, usually by
earthquake activity. Seiches are of concern relative to water storage facilities because i=undation from a seizhe
can occur if the wave overflows a containment wail, such as the wall of a reservoir, water storage tank, dam, or
other artificial body of water. Neither the Reuse Plan area nor the infill areas are located near any' confiner;

Exposure of persons to or generation ot' noise levels in excess of slandards established in the local general
plan or noise ordinance, or applicable standards of other agencies?
Noise impacts can be brok'en down into ti*cee categories. The iirst is "audible" impacts, wit/ch refers to
increeses in noise level that are t~ercemible to humans. Audible increases in noise ievels generally' refer lo a
change of*.,h:'ee dBA or more since ',.his level has been found to be barely perceptible in exterior enviro::mems.
The second category, "potentia!}y audible." refers to a change in noise level between one and three dBA. Tiffs
range of nmse levels was found to be noticeable to sens."tive people in iaboratory' environments. The last
category is cl:anges in noise level of less titan one dBA that are t}~mally "inaudibW' to the human ear except
under quiet conditions in controlied environments. Only "audible" changes in noise level are considered as
polen:iaEy significant.
.Vlobile-sot::':'.e noise (i.e. vehicles) is preen:p:zd from ioza: regu:atlon. For mobile svu:'ces, an impact would be
considered significant if :he prtgec: we:re to increase noise by' 3 dBA (a bare'.'3' discemable increase) arid fix:
resultant nmse exceeded the City's noise standards, or 5 dBA (notable to most people) if',.he resuhant noise
contained below City standards.
Thc proposed project sfie is located w/thin tke C2v of Tustin and thus is subject to t.he General Plan and existing
Ciry's noise ordinances. The General Plan discusses the effects of noise exposure on fi~e population and sees
ianduse compa:Jbiii:y goa~s aimed at p:otecting residents from undue noise. The Plan follows tile

A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels
existing without the project?
Noise ,evAs associated w:th :ons~uction activities wouid be higher than the ambient noise levels in the City,
but would subside once construction of :he residential units proposed in the Housing Element Update are
completed.
Two t).,pes of noise impacts could occur during the construction phase. First, the u'ansport of workers and
equipment to the construction site would incrementally increase noise levels along site access roadways. Eve~:
though there would be a rela,.ive!y high single event noise exposure potential with passing trucks (a maximum
noise !evel of 86 dBA a~ 50 feet), the increase in noise would be less 'dan one dBA when average'J over a 24-
hour period and should ~erefore have a less that. significant impact at noise receptors aiong City' track rou:es.
'f'he second t3~ae of impact is related zo noise generated 53' on-site construction operation.5. Local residents
would be subject to elevated noise levels due to the operation of on-site constm:tion equipment. Construction
a:dvities are c~"ried out in discrete steps, eack of which has !ts own mix of equipment, and consequently ~ts
own noise characteristics. Table 2 lists t3pical construction equipment noise ~evels recommended ~br noise
impact assessment at a distance of 50 feet.
.No[se ranges have been found to be similar during all phases of construction, altimugh the erection phase tends
to be less noisy. Noise kvels range up to 89 dBA at 50 feet during the erection phase of consmaction, which is
approximately 2 dBA lower than other construction phases. Thc grading and site preparation phase tends to
create the highest noise levels, because the noisiest :onsu'uction eq'A.?,men: is found in the eartnmovm~
equipment category. 'E'~is category includes excavating mac?:ine:'y (back_qllers, bulldozers, draglines, ,~Lqnt
~oaders, etc.) and earthmoving and compa:ting equipment (compac*.ors, scrapers, graders, crc). T3.pica!

Fire protection
Thc City of Tustin contracts with thc Orange County Fire AuthoriD' (OCPA) for fire protection services. The
Fire Authoril3.' maintains tlxree stations in the CID',
New housing developments would increase demand for ike protect/on, as ~ ~:. as emergency medical services.
IndMdual development proje:,ts wouid be required to meet ex!sting OCFA regulations regarding construction
mater, als and methods, emergency access, water mains, tire flow, fire hydrants, sprinkler systems, building
setbacks, and other relevant ?.~Aations. Adherence to the OCFA reguiations would reduce the risk of
uncontrollable fire and increase the abihty m efficien:ly provide £Lre protection services to the City. The number
of fir:: stations in the areas surrounding the site will meet the demands created by the proposed project.
Police r~rotection
':'l;e Cny of Tustin operates ~zs o~m Police Department. New housing developmenu a: the MC...',S-'fustin Reuse
Plan area would increase tko need for police emergency and protection sen'ices. The need for taoiice pro~ection
sen'ices is assessed on the basis of resident population estimates, square footage of industrial uses, and square
footage of retail uses. The Program EIS:'EIR for .MCAS-Tusrin identiEes il:a: the need for additional police
services could be accommodated at Sue ex/sting City police station and no new foci!it!es would be required.
'.q. ci:oels
Development of adclitional housing would induce population growth, therefore increasing the number of school
age children. Of t?.e 3,298 housing units proposed in the Housing Element Update, approximate!y 397 uni'~s
could be developed in Ln.fill areas. Most housing development anticipated would be located m the MCAS-
Tusfin Reuse Plan area.
The Reuse P~an is located x~:thin the Tustin Unified School District ('Il'SD), lrx'ine Unified School Disu-.ict
(!USD), and Soma Aha Unified School DisMct (SAUSD). However, all the housing units proposed under tire
Housing Elemem Update wil! be located w/thin the TUSD and [LISD. The implementat:on of tee Reuse Pian
wo..'id nrovide ~or cwo 10-acre elememary school seres and one 40-acre Sigh school sire within :he TLTSD. The
'iL:SD has agreed that these sites wo,,:ld be considered adequate to accom,m, oda:e new students generated by fne
Reuse Plan development, as well as some of tim future growth anticioa~ed for the Tustin community as a whole.
With remec~ to the IUSD, ti~e imp]ememation of the Reuse Pla:: would provide for a 20-ae:'e school site to
IUSD to se."v~ tire growing student population 'Mthm its district. Wifl~ respect to the SAUSD, although no
housing exis:s in this area to be reused m:d no new housing would be consu'uc~ed in its boundaries, indirectly
new students could be gc::era~c,'J through the p:.'ovision of new employm',:'n:. The commercial uses would

co.manunity college facilities because students h~ Tustin can attend any con~nuniry college in :he CounD'.
Therefore, except for conswacnon level impacts which will be mitigated to a level of insi~ifican:c due to
required compliance with existing CiLv regulations, no other school impacts are anticipated.
With respect to the infil! areas, all potential si:es are located with.in the 'IUSD boundaries. Furore anticipated
g-rowth for tine anticipated infil] sites will be assessed school !moact fees to accommodate any impacts to
exist/n,, schools.
Parks
The City of Tustin cun'cntly has 12 corks and 4 con~munity.'recreation facilities. The implementation of the
MCAS-Tustin Reuse Plan would provide new park s:t:s. These park sites :nciude a regional park, a commmnity
park, and several smaller neighborhood parks. A privately owned golf course would be cor~st:ructed as well but
would be available for pubh: usage. These facilities would provide park and recreation oppo.nunities to the
population of the Reuse Plan areas as well as the CiLv and '~he region and their development will no: result in a
significant impact on the environment. Once constrncted, these parks u'ou]d meet reside:trial popu:afion
demand. The existing parks in the City of Tustin will sen'e new development as well.
Other p. ubiic facilities
Most of the development of these new housing units would be provided w/thin 'dee MCAS-'l-ustin area. The
Program EIS.'EIR for MCAS-Tusfin discusses in\=azts related ;o other public facilities that may result fi'om the
implementation cf the Reuse Plan. These facil!ties include libraries and recreational 'eikeway trails.
· Library
Using thc County's criteria, the imNementation of the Reuse Plan would result in a demand of up to
approximately 2,500 square feet of library space. 'Fnis relatively small amount of space is ,,eli below the
library system's general minimum size of 10,000 souare fee~ for a branch librar,.', and would no~ u'igger the
need for a new faciliLv. Therefore, '3~ere would be no significant effects on ~he environment.
· Recreational Bikeway Trai!s
hnpleme::.'.arion of the Reuse Plan would include bikeway, riding and hiking trails, although such is not
r~ouired by the Hoc:sing Element Up,.ate. A Class i and Class 1i bikeway.'riding and inking u'ai! would be
conszmcted by the County of Orange. This system would connect vital lites necessary for a
corrrprehensive regional and improv:d lo:.al bikeway riding and hiking trail system and would be a
beneficial itwpact.
Wi.'.h respect to th= Shrill areas, consis;ent with the policies of the CiLv's Circuiation Element, the City
woukt support and coordinate ti~e development and maintenance of bikeway riding and baking trails with
the County of Orange. As d:veiopmem o'.' bikeways, tra:is occur, City regulations would reduce
construction related impacts to a level of insignificance.
General lrrro!ementat/on Requirements:
To support development in the reuse plan area, the Reuse Plain Specific Plan requires public sen'ices and fac!l!ties to
be provided concurrent witi~ demand. The implementation of the Housing Element Update a'~ the reuse plan wili be

a)
Cause an increase in traffic, which is substantial in relation to the existing traffic load and eapaci~- of the
street system (i.e. result in a substantial increase in either the number of vehicle trips, the volume to
capaciLv ratio on roads, or congestion at intersections)?
The Housing Element Update anticipates developmen: up to an additional 3,298 housing units. Th2s
develoament would be located m ',.he MCAS-Tustin Reuse Plan and at thrill sites. The additional development
and associated traffic volurnes of developing the Reuse Plan are included Ln the traffic analysis portion of the
Program EIS'EIK for MCAS-Tustin. As the impacts of traffic due to ho,.:sing alone wer.- not separated out and
anai)~ed, the £ollowing cliscussion includes impacts due to commercial, industrial, and institutional uses, as well
as housing. In general, a number of imersections would be si~nifica.ntiy impacted at the buildout offi~,e Reuse
Plan. Most of :hose impacted can be mitigated to a level of less than significant. However, sLzmficant tra£~.c
impac:s would remain a: the mtersectiml~ of Tustin Ranch Road and Walnut Avenue, and Jamboree Road and
Barranca Parkway under full builtout (yea.- 2020).
Infill areas are located within the established street system. Although generally u'affic in the City of Tustin is
within the level of service stander& '&ere arc intersections fi;at are at unacceptable level of se~:ice. Through the
City's existing Dcsig'n Review process, development located at an unacceptable level of service which
comributes :0 percent or more of traffic will be assessed with mitigation fee as part of the City's Capital
Im:~rovement Program. in addi:ion, where applicable, thc City would re~.ui.re dedica~on of r:gkt-of-ways
and or require devdopers :o construct the needed improvements to ima:'ove the level of service. Theft'fore,
compliance with the existing City's regula'dons would reduce potential ~raffic im~,ac~s to a level that is less
significant.
in surf. mary. the implementation of the Housing E!emen:. Update, particularly the development at the .MCAS-
Tustin Reuse Plan area, would potentially result in ummitigable impacts at -cwo intersections described above.
However, the implementation of the Housing Element Update would not resu:.t in any impacu beyond those
identified in the Pro,'am EIS EIR for MCAS-Tustin. No further rmtigation measures would be required beyond
those identified in the Program ElS EIR for MCAS-Tustin.

Infil! developments would be subject to review to ensure that individual deveio~men! would nc: exceed the
level of se,wice standards, individually or cumulatively. Compliance with the Cit-y's Circulation Element and
CiL'y Ordinances related to streets and highways would reduce potential traffic impacts to a ievel that is less than

3. $7' MANDATORY F/NOING$ OF SIGNIFICANCE
a) Does the project have the potential to degrade the quality of the environment, substantially reduce the
habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels,
threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or
endangered plant or animal or eliminate important examples of the major periods of California history
or prehistory?
b)
Does the project have impacts that are individually limited, but cumulatively considerable?
("Cumulatively considerable" means that the incremental effects of a project are considerable when
viewed in connection with the effects of past projects, the effects of other current projects, and the effects
of probable future projects.)
c)
Does the project have environmental effects, which will cause substantial adverse effects on human
beings, either directly or indirectly?
The adoption of the Housing Elemen: Update would no: cause negative impacts. However the tmplementatio:~
of' the MCAS-Tustin Rause Plan t:xrough the General Plan Amendment and subsequent zo:fing could cause
sibm. ifican; impacts to the envirommei;t. These impacts are identified in tl~e Prog:'am EI$..mEI]'~. for MCAS-Tustin.
