225 AFFORDABLE MULTI - FAMILY RESIDENTIAL
APARTMENT HOMES, TUSTIN LEGACY (ST. ANTON
PARTNERS, LLC). AND THAT THE CITY HAS
ALTERNATIVELY DETERMINED THAT THE PROPOSED
PROJECT IS EXEMPT FROM FURTHER CEQA REVIEW
PURSUANT TO GOVERNMENT CODE SECTION 65457.
The City Council of the City of Tustin does hereby resolve as follows:
The City Council finds and determines as follows:
A. That St. Anton Partners and City of Tustin have completed and desire to
enter into Disposition and Development Agreement 2012 -002, and St.
Anton Partners has submitted a proper application for DA 2012 -002, CP
2012 -003, DR 2012 -005, Density Transfer, and Density Bonus requesting
authorization to develop 225 affordable residential apartment housing
units in compliance with California Government Code Section 65915(1)
required for the proposed development of Tustin Legacy Disposition
Package 1A- North, to be implemented by St. Anton Partners or its affiliate
as may be approved by the City of Tustin.
B. That the site is zoned as Planning Area 15, Community Residential,
Neighborhood G in the MCAS Tustin Specific Plan (SP -1); and designated
MCAS Tustin (MCAS) by the Tustin General Plan. In addition, the project
has been reviewed for consistency with the Air Quality Sub - element of the

the Air Quality Sub-element.
iuw
There are no substantial changes in the project requiring major revisions
C. That on January 16, 2001, the City of Tustin Certified the Program Final
Environmental Impact Statement/Environmental Impact Report (FEIS/EIR)
for the disposal and reuse of MCAS Tustin pursuant to, among other
things, the MCAS Tustin Specific Plan/Reuse Plan. On December 6,
2004, the City Council adopted Resolution No. 04-76 approving the
MEN
Supplement to the FEIS/EIR 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 FEIS/EIR for modifications to the MCAS
Tustin Specific Plan/Reuse Plan. The FEIS/EIR, Supplement to the
FEIS/EIR, and Addendum are collectively referred to as the "Prior
Environmental Review."
D. That the City prepared an environmental checklist and determined that the
proposed project is within the scope of the Prior Environmental Review.
There are no substantial changes in the project requiring major revisions
to the Prior Environmental Review, substantial changes with respect to the
circumstances under which the project is being undertaken which will
require major revisions to the Prior Environmental Review, or any new
information which was not known and could not have been known at the
time the Prior Environmental Review was certified showing that: (1) the
MEN
project will have any new significant effects; (2) significant effects
previously examined will be substantially more severe; (3) mitigation
measures or alternatives previously determined to be infeasible will now
be feasible and would substantially reduce one or more significant effects
of the project but the City declined to adopt the mitigation measure or
alternative; or (4) mitigation measures or alternatives considerably
different from those previously analyzed would substantially reduce one or
more significant effects on the environment, but the City declined to adopt
the mitigation measure or alternative. (Public Resources Code § 21166;
Cal. Code Regs., Tit. 14, §§ 15168, 15162.) The City has therefore
determined that no further environmental review is required.
E. That Government Code Section 65457, subdivision (a), establishes a
statutory CEQA exemption for any residential development project,
including any subdivision, or zoning change that is undertaken to
implement and is consistent with a specific plan for which an EIR was
certified after January 1, 1980. The exemption does not apply if an event
specified in Public Resources Code Section 21166 occurs, unless and
until a supplemental environmental impact report is certified. Here, the
proposed project implements and is consistent with the MCAS Tustin
Specific Plan / Reuse Plan. The FEIS/EIR for the reuse of MCAS Tustin
pursuant to, among other things, the MCAS Tustin Specific Plan/Reuse
Resolution 12-96
Page 2 of 4
Plan, was certified January 16, 2001. And, as set forth above, the City
prepared an environmental checklist and determined that none of the
events specified in Public Resources Code Section 21166 have occurred.
On this basis, the City has alternatively determined that the proposed
project is exempt from further CEQA review pursuant to Government
Code Section 65457.
F. That in accordance with the provisions of the California Environmental
Quality Act (CEQA), the checklist provided as Attachment 1 to Resolution
No. 12-96 has been considered and found to be complete and adequate
prior to approving the project as proposed.
G. That on October 16, 2012, the Tustin City Council continued the matter to
an adjourned regular meeting on October 30, 2012.
H. That on October 30, 2012, the Tustin City Council continued the matter to
a regular meeting on November 6, 2012.
11. The Tustin City Council hereby finds the Project is within the scope of the
previously approved MCAS Tustin Final Program EIS/EIR previously certified on
January 16, 2001, as amended by Supplement and Addendum and that no new
effects could occur and no new mitigation measures would be required and an
additional environmental analysis, action or document is not required by the
CEQA. The City has alternatively determined that the proposed project is exempt
from further CEQA review pursuant to Government Code Section 65457.
PASSED AND ADOPTED by the City Council of the City of Tustin at an adjourned
regular meeting held on the 6t" day of November, 201?.

ENVIRONMENTAL ANALYSIS CHECKLIST
For Projects With Previously Certified/Approved Environmental Documents:
Environmental Impact Statement/Environmental Impact Report (EIS/EIR)
for the Disposal and Reuse of Marine Corps Air Station (MCAS) Tustin
The following checklist takes into consideration the preparation of an environmental document prepared at an
earlier stage of the proposed project. This checklist evaluates the adequacy of the earlier document pursuant to
Section 15162 and 15168 of the California Environmental Quality Act (CEQA) Guidelines.
A. BACKGROUND
Project Title(s): Proposed development of Tustin Legacy Disposition Package lA-North — 225
affordable multi -family residential apartment homes. The proposal requests City
of Tustin consideration of Development Agreement (DA) 2012-002, Concept Plan
(CP) 2012-003, Design Review (DR) 2012-005, Density Transfer, Density Bonus,
and Concessions or Incentives authorized under Tustin City Code Section 9123
related to the provision of affordable residential apartment housing units in
compliance with California Government Code Section 65915(1) required for the
proposed development of Tustin Legacy Disposition Package 1A -North.
Lead Agency: City of Tustin, 300 Centennial Way, Tustin, California 92780

B.
Incentives authorized under Tustin City Code Section 9123 related to the
provision of affordable housing units in compliance with California Government
Code Section 65915(1)(MCAS Tustin Planning Area 15) for the purpose of
developing 225 multi -family residential apartment homes including 105
affordable units (35 very low income, 20 low income and 50 moderate income),
which qualifies the project for a density bonus concessions or incentives
authorized under Tustin City Code Section 9123 related to the provision of
affordable housing units in compliance with California Government Code Section
65915(1). In addition, the project applicant has partnered with The Irvine
Company, LLC, a developer approved by the City of Tustin to develop
Disposition Package 2A in Planning Area 13, and requested the transfer of 120 of
the 157 affordable housing units from Disposition Package 2A to Disposition
Package IA -North with 120 market rate units requested to be transferred from
Disposition Package IA -North to Disposition Package 2A. Should the Tustin
City Council approve the transfer request, the proposed development of
Disposition Package 2A would include 37 moderate unit income units and 496
market rate units (for a total of 533 residential apartment units), and the proposed
development of Disposition Package IA -North would include a total of 225
affordable residential apartment units (88 very low income, 73 low income, and
64 moderate income). The proposed use is consistent with the approved Specific
Plan.
Surrounding Uses: North/East: Vacant — MCAS Tustin Planning Area 15, Residential Core.
West: Vacant — MCAS Tustin Planning Area 8, Community Core
South: Vacant — MCAS Tustin Planning Area 15, Residential Core
Previous Environmental Documentation: On January 16, 2001, the City of Tustin certified the Program
Final Environmental Impact Statement/Environmental Impact Report (FEIS/EIR) for the 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 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. The FEIS/EIR along with its
Supplemental and Addendum is a program EIR under the California Environmental Quality Act
(CEQA). The FEIS/EIR, Supplemental and Addendum considered the potential environmental impacts
associated with development on the former Marine Corps Air Station, Tustin.

have been added to the project. A NEGATIVE DECLARATION will be prepared.
❑ I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
❑ I find that the proposed project MAY have a significant effect(s) on the environment, but at least one
effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and
2) has been addressed by mitigation measures based on the earlier analysis as described on attached
sheets, if the effect is a "Potentially Significant Impact" or "Potentially Significant Unless Mitigated."
An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that
remain to be addressed.
® I find that although the proposed project could have a significant effect on the environment, there WILL
NOT be a significant effect in this case because all potentially significant effects 1) have been analyzed
adequately in an earlier EIR pursuant to applicable standards, and 2) have been avoided or mitigated
pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the
proposed project.

INCENTIVES AUTHORIZED UNDER TUSTIN CITY CODE SECTION 9123 RELATED TO THE
PROVISION OF AFFORDABLE HOUSING UNITS IN COMPLIANCE WITH CALIFORNIA
GOVERNMENT CODE SECTION 65915(1).
BACKGROUND
On January 16, 2001, the City of Tustin certified the Program Final Environmental Impact
Statement/Environmental Impact Report (FEISIEIR) for the reuse and disposal of MCAS Tustin.
On April 3, 2006, the City Council adopted Resolution No. 06-43 approving an Addendum to the
FEiS1EIR. And, on December 6, 2004, the City Council adopted Resolution No. 04-76
approving a Supplement to the FEISIEIR for the extension of Tustin Ranch Road between
Walnut Avenue and the future alignment of Valencia North Loop Road (collectively, "Prior
Environmental Review"). The FEISIEIR along with its Addendum and Supplement is a program
EIR under the California Environmental Quality Act (CEQA). The FEISIEIR, Addendum and
Supplement considered the potential environmental impacts associated with development on
the former Marine Corps Air Station, Tustin.
The FEISIEIR, Addendum and Supplement analyzed the environmental consequences of the
Navy disposal and local community reuse of the MCAS Tustin site per the Reuse Plan and the
MCAS Tustin Specific Plan/Reuse Plan (referred to in this document as the Specific 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.
The MCAS Tustin Specific Plan proposed and the FEISIEIR analyzed a multi-year development
period for the planned urban reuse project (Tustin Legacy). When individual discretionary
activities within the Specific Plan are proposed, the lead agency is required to examine the
individual activities to determine if their effects were fully analyzed in the FEISIEIR. The agency
can approve the activities as being within the scope of the project covered by the FEISIEIR. If
the agency finds that pursuant to Sections 15162, 15163, 15164, and 15183 of the CEQA
Guidelines no new effects would occur, nor would a substantial increase in the severity of
previously identified significant effects occur, then no supplemental or subsequent EIR is
required.
The project site is 8.073 acres for multi -family development and 4.706 acres for park
development (12.779 acres gross) located within the MCAS Tustin Specific Plan boundaries
affecting only Disposition Package 1A -North, which is an irregular parcel within Planning Area
15 of Neighborhood G. The project site is bounded by future Tustin Ranch Road on the east,
future Legacy Road on the north, future Park Avenue on the west, and a vacant parcel to the
south.
The proposed development of Tustin Legacy Disposition Package 1A -North is to construct 225
multi -family residential apartment homes ("Project"). The proposal requests City of Tustin
consideration of Development Agreement (DA) 2012-002, Concept Plan (CP) 2012-003, Design
Review (DR) 2012-005, Density Transfer, Density Bonus, and Concessions or Incentives
authorized under Tustin City Code Section 9123 related to the provision of 225 affordable
residential apartment housing units in compliance with California Government Code Section
65915(1).
The Project proposes to develop 225 multi -family residential apartment homes includes 105
affordable units (35 very low income, 20 low income and 50 moderate income), which qualifies

the Project for a density bonus concessions or incentives authorized under Tustin City Code
Section 9123 related to the provision of affordable housing units in compliance with California
Government Code Section 65915(1). In addition, the Project applicant has partnered with The
Irvine Company, LLC, a developer approved by the City of Tustin to develop Disposition
Package 2A in Planning Area 13, and requested the transfer of 120 of the 157 affordable
housing units from Disposition Package 2A to Disposition Package 1A -North with 120 market
rate units requested to be transferred from Disposition Package 1A -North to Disposition
Package 2A. Should the Tustin City Council approve the transfer request, the proposed
development of Disposition Package 2A would include 37 moderate unit income units and 496
market rate units (for a total of 533 residential apartment units), and the proposed development
of Disposition Package 1A -North would include a total of 225 affordable residential apartment
units (88 very low income, 73 low income, and 64 moderate income). The final proposed
allocation of units is as follows:
In accordance with the MCAS Tustin Specific Plan, Planning Area 15 allows Medium -High
Density Residential at 16-25 dwelling units per acre. The Project proposes a density of
approximately 17.6 dwelling units per acre. Due to the fact that the Site 2A/Site 1A -North
projects propose 262 of 758 total units as affordable rental units (35%), the combined projects
include (and qualify for) a request for density bonus, concessions or incentives authorized under
Tustin City Code Section 9123 related to the provision of affordable housing units in compliance
with California Government Code Section 65915(1).
An Environmental Analysis Checklist has been completed and it has been determined that the
Project is within the scope of the Prior Environmental Review and that pursuant to Public
Resources Code Section 21166 and Title 14 California Code of Regulations Sections 15162
and 15168(c), there are no substantial changes in the project requiring major revisions to the
Prior Environmental Review , substantial changes with respect to the circumstances under
which the project is being undertaken which will require major revisions to the Prior
Environmental Review, or any new information which was not known and could not have been
known at the time the Prior Environmental Review was certified showing that: (1) the project will
have any new significant effects; (2) significant effects previously examined will be substantially
more severe; (3) mitigation measures or alternatives previously determined to be infeasible will
now be feasible and would substantially reduce one or more significant effects of the project but
the City declined to adopt the mitigation measure or alternative; or (4) mitigation measures or
alternatives considerably different from those previously analyzed would substantially reduce
one or more significant effects on the environment, but the City declined to adopt the mitigation
measure or alternative. Accordingly, no new environmental document is required by CEQA.

AESTHETICS —Would the project:
a) Have a substantial adverse effect on a scenic vista?
b) Substantially damage scenic resources, including, but not limited to, trees,
rock outcroppings, and historic buildings within a state scenic highway?
c) Substantially degrade the existing visual character or quality of the site and its
surroundings?
d) Create a new source of substantial light or glare, which would adversely affect
day or nighttime views in the area?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The project is not located on a scenic highway nor will it affect a scenic vista. The project
would be consistent with the permitted uses identified within the MCAS Tustin Specific
Pian. The development of residential apartment units within Planning Area 15 were
considered within the FEIS/EIR and will have no negative aesthetic effect on the site when
mitigation measures identified in the FEIS/EIR are incorporated with approval of the
project. All exterior design is required to be in compliance with Section 2.17.3(A) — Urban
Design Guidelines for Residential Development of the MCAS Tustin Specific Plan, and the
Landscape Concept Section 2.17.2 as they relate to design of Tustin Ranch Road, Legacy
Road, Park, Park Avenue and primary street corners and project entries. The proposal
includes a design review and concept plan application, which requires that the Planning
Commission and City Council review and ensure the design of the project, if approved, is
found to be cohesive and in harmony with surrounding uses. All exterior lighting would be
designed to reduce glare, create a safe night environment, and avoid impacts to
surrounding properties in compliance with Section 2.17.3 (A) of the MCAS Tustin Specific
Plan and the City's Security Ordinance. The proposed project will result in no substantial
changes to the environmental impacts previously evaluated with the certified Program
FEIS/EIR, the Supplemental and Addendum.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental El or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to aesthetics. Specifically, there Have not been: (1) changes to the Project that
require major revisions of the previous FEIS/EIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously
identified effects; (2) substantial changes with respect to the circumstances under which
the Project is undertaken that require major revisions of the previous FEISIEIR due to
the involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; or (3) the availability of new information of
substantial importance relating to significant effects or mitigation measures or
alternatives that were not known and could not have been known when the FEISIEIR,
the Supplemental or Addendum were certified as completed.
Mitigation/Monitoring Required. No new impacts nor substantially more severe aesthetic
impacts would result from the adoption and implementation of the Project; therefore, no
new or revised mitigation measures are required for aesthetics and visual quality. No
refinements related to the Project are necessary to the FEIS/EIR mitigation measures
and no new mitigation measures are required. Mitigation measures were adopted by the
Tustin City Council in the FEIS/EIR, Addendum and Supplement; and applicable measures

AGRICULTURE RESOURCES: In determining whether impacts to agricultural
resources are significant environmental effects, lead agencies may refer to the
California Agricultural Land Evaluation and Site Assessment Model (1997)
prepared by the California Dept. of Conservation as an optional model to use in
assessing impacts on agriculture and farmland. Would the project:
a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide
Importance (Farmland), as shown on the maps prepared pursuant to the
Farmland Mapping and Monitoring Program of the California Resources
Agency, to non-agricultural use?
b) Conflict with existing zoning for agricultural use or a Williamson Act contract?
c) Involve other changes in the existing environment which, due to their location
or nature, could result in conversion of Farmland to non-agricultural use?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan. As
documented in the FEISIEIR, the project site is part of MCAS Tustin Specific Plan that
contained 702 acres of farmland. The FEISIEIR concluded that there would be no viable
long-term mitigation to off -set the impact of converting farmland on MCAS Tustin to urban
uses.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to agricultural resources. Specifically, there have not been: (1) changes to the
Project that require major revisions of the previous FEISIEIR due to the involvement of
new significant environmental effects or a substantial increase in the severity of
previously identified effects; (2) substantial changes with respect to the circumstances
under which the Project is undertaken that require major revisions of the previous
FEISIEIR due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.
MitigationlMonitoring Required: Specific mitigation measures have been adopted by the
Tustin City Council in certifying the FEISIEIR. However, the FEISIEIR also concluded that
Reuse Plan related impacts to farmland were significant and impossible to fully mitigate. A
Statement of Overriding Consideration for the FEISIEIR was adopted by the Tustin City
Council on January 16, 2001.

Ill. AIR QUALITY: Where available, the significance criteria established by the
applicable air quality management or air pollution control district may be relied
upon to make the following determinations. Would the project:
a) Conflict with or obstruct implementation of the applicable air quality plan?
b) Violate any air quality standard or contribute substantially to an existing or
projected air quality violation?
c) Result in a cumulatively considerable net increase of any criteria pollutant for
which the project region is non -attainment under an applicable federal or state
ambient air quality standard (including releasing emissions that exceed
quantitative thresholds for ozone precursors)?
d) Expose sensitive receptors to substantial pollutant concentrations?
e) Create objectionable odors affecting a substantial number of people?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan. As
documented in the FEISIEIR, the project is part of a larger reuse project at Tustin Legacy
that was projected to result in air quality impacts that cannot be fully mitigated. A
Statement of Overriding Consideration for the FEISIEIR was adopted by the Tustin City
Council on January 16, 2001. The site is presently not in use. The project applicant
proposes to construct 225 units on 12.779 acres (17.6 dwelling units per acre), which is
less that the allowable density of the site (16-25 dwelling units) as identified in the MCAS
Tustin Specific Plan. Therefore, no significant impact beyond what was analyzed in the
adopted FEISIEIR is anticipated. The City must support density bonus requests,
concessions or incentives when projects provide affordable housing units in compliance
with California Government Code Section 65915(1), as authorized under Tustin City
Code Section 9123.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to air quality. Specifically, there have not been: (1) changes to the Project that
require major revisions of the previous FEISIEIR due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously identified
effects; (2) substantial changes with respect to the circumstances under which the Project
is undertaken that require major revisions of the previous FEISIEIR due to the involvement
of new significant environmental effects or a substantial increase in the severity of
previously identified effects; or (3) the availability of new information of substantial
importance relating to significant effect or mitigation measures or alternatives that was not
known and could not have been known when the FEISIEIR was certified as complete.
Mitigation/Monitoring Required: Specific mitigation measures have been adopted by the
Tustin City Council in certifying the FEISIEIR. However, the FEISIEIR also concluded that
Reuse Plan related operational air quality impacts were significant and impossible to fully

IV. BIOLOGICAL RESOURCES: -Would the project:
a) Have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or special
status species in local or regional plans, policies, or regulations, or by the
California Department of Fish and Game or U.S. Fish and Wildlife Service?
b) Have a substantial adverse effect on any riparian habitat or other sensitive
natural community identified in local or regional plans, policies, regulations, or
by the California Department of Fish and Game or U.S. Fish and Wildlife
Service?
c) Have a substantial adverse effect on federally protected wetlands as defined
by Section 404 of the Clean Water Act (including, but not limited to, marsh,
vernal pool, coastal, etc.) through direct removal, filling, hydrological
interruption, or other means?
d) Interfere substantially with the movement of any native resident or migratory
fish or wildlife species or with established native resident or migratory wildlife
corridors, or impede the use of native wildlife nursery sites?
e) Conflict with any local policies or ordinances protecting biological resources,
such as a tree preservation policy or ordinance?
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Community Conservation Plan, or other approved local, regional or state
habitat conservation plan?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The FEISIEIR found that implementation of the Reuse Plan and MCAS Tustin Specific Plan
would not result in impacts to federally listed threatened or endangered plant or animal
species. The proposed project is within the scope of development considered with the
analysis of the FEISIEIR, the Supplemental and Addendum for MCAS Tustin. The
FEISIEIR determined that implementation of the Reuse Plan and MCAS Tustin Specific
Plan (including the proposed project) could impact jurisdictional waterstwetlands and the
southwestern pond turtle or have an impact on jurisdictional waters/wetlands. The project
site has been surveyed, and turtles were captured and moved off the site to another
location as directed and overseen by the California Department of Fish and Game. Since
that time, all former Marine Corps base drainage channels in the area were removed and
882601.1

Page 7
graded by the former owner of the property with the required 401, 404 and 1601 pen -nits
issued by Fish and Game, Army Corps of Engineers, and Regional Water Quality Control
Board. Consequently, the proposed project would not affect the southwestern pond turtle
or have an impact on jurisdictional waters or wetlands. No substantial change is expected
from the analysis previously completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to biological resources. Specifically, there have not been: (1) changes to the Project
that require major revisions of the previous FEISIEIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously
identified effects; (2) substantial changes with respect to the circumstances under which the
Project is undertaken that require major revisions of the previous FEISIEIR due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; or (3) the availability of new information of
substantial importance relating to significant effect or mitigation measures or alternatives
that was not known and could not have been known when the FEISIEIR was certified as
complete.
Mitigation/Monitoring Required: No mitigation is required.

V. CULTURAL RESOURCES: - Would the project:
a) Cause a substantial adverse change in the significance of a historical resource
as defined in §15064.5?
b) Cause a substantial adverse change in the significance of an archaeological
resource pursuant to § 15064.5?
c) Directly or indirectly destroy a unique paleontological resource or site or
unique geologic feature?
d) Disturb any human remains, including those interred outside formal
cemeteries?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The former MCAS Tustin contained two National Register listed blimp hangars, and
several concrete or asphalt blimp landing pads that were considered historically or
culturally significant, pursuant to the federal Section 106 process conducted at the site.
A portion of the previously existing blimp pads are within the project site boundary that,
through the Section 106 process, were identified as part of a discontiguous Historic District.
The Navy, State Office of Historic Preservation (SHPO), and Advisory Council executed a
Memorandum of Agreement (attached as part of the EISIEIR) with City of Tustin and
County of Orange as invited signatories that allowed for the destruction of the blimp pads.
The EISIEIR noted that it may not be financially feasible to retain the blimp Dangers and
there may be irreversible significant impacts. A Statement of Overriding Consideration for
882601.1
Evaluation of Environmental Impacts

Page 8
the FEIS/EIR was adopted by the Tustin City Council on January 16, 2001. Consistent with
the above referenced agreement, the previous owner of the property removed the blimp
pad from the project site and leveled the property.
Numerous archaeological surveys have been conducted at the former MCAS Tustin site.
In 1988, the State Office of Historic Preservation (SHPO) provided written concurrence that
all open spaces on MCAS Tustin had been adequately surveyed for archaeological
resources. Although one archaeological site (CA -ORA -381) has been recorded within the
Reuse Plan area, it is believed to have been destroyed It is possible that previously
unidentified buried archaeological or paleontological resources within the project site could
be significantly impacted by grading and construction activities. With the inclusion of
mitigation measures that require construction monitoring, potential impacts to cultural
resources can be reduced to a level of insignificance. No substantial change is expected
from the analysis previously completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to cultural resources. Specifically, there have not been: (1) changes to the Project
that require major revisions of the previous FEISIEIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously
identified effects; (2) substantial changes with respect to the circumstances under which the
Project is undertaken that require major revisions of the previous FEISIEIR due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; or (3) the availability of new information of
substantial importance relating to significant effect or mitigation measures or altematives
that was not known and could not have been known when the FEISIEIR was certified as
complete.
MitigatiorVMonitoring Required. Mitigation measures have been adopted by the Tustin City
Council in the FEISIEIR; these measures would be included as conditions of approval for
the project.

VI. GEOLOGY AND SOILS: — Would the project:
a) Expose people or structures to potential substantial adverse effects, including
the risk of loss, injury, or death involving:
• Rupture of a known earthquake fault, as delineated on the most recent
Alquist-Priolo Earthquake Fault Zoning map, issued by the State Geologist
for the area or based on other substantial evidence of a known fault? Refer
to Division of Mines and Geology Special Publication 42.
• Strong seismic ground shaking?
• Seismic -related ground failure, including liquefaction?
• Landslides?

Evaluation of Environmental Impacts
DA 2012-002, CP 2012-003, DR 2012-005, Density Transfer, and Density Bonus
Page 9
b) Result in substantial soil erosion or the loss of topsoil?
c) Be located on a geologic unit or soil that is unstable, or that would become
unstable as a result of the project, and potentially result in on- or off-site
landslide, lateral spreading, subsidence, liquefaction or collapse?
d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform
Building Code (1994), creating substantial risks to life or property?
e) Have soils incapable of adequately supporting the use of septic tanks or
alternative wastewater disposal systems where sewers are not available for the
disposal of wastewater?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The FEISIEIR indicates that impacts to soils and geology resulting from implementation of
the Reuse Plan and WAS Tustin Specific Plan would "include non -seismic hazards (such
as local settlement, regional subsidence, expansive soils, slope instability, erosion, and
mudflows) and seismic hazards (such as surface fault displacement, high-intensity ground
shaming, ground failure and lurching, seismically induced settlement, and flooding
associated with dam failure." However, the FEISIEIR for WAS Tustin also concluded that
compliance with state and local regulations and standards, along with established
engineering procedures and techniques, would avoid unacceptable risk or the creation of
significant impacts related to such hazards. No substantial change is expected for
development of the project from the analysis previously completed in the FEISIEIR for
MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to geology and soils. Specifically, there have not been: (1) changes to the Project
that require major revisions of the previous FEISIEIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously
identified effects; (2) substantial changes with respect to the circumstances under which
the Project is undertaken that require major revisions of the previous FEISIEIR due to
the involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; or (3) the availability of new information of
substantial importance relating to significant effects or mitigation measures or
alternatives that were not known and could not have been known when the FEISIEIR,
the Supplemental or Addendum were certified as completed.
Mitigation/Monitoring Required: As identified in the FEISIEIR, compliance with existing rules
and regulations would avoid the creation of potential impacts. No mitigation is required.

VII. HAZARDS AND HAZARDOUS MATERIALS: —Would the project:
a) Create a significant hazard to the public or the environment through the
routine transport, use or disposal of hazardous materials?
b) Create a significant hazard to the public or the environment through
reasonable foreseeable upset and accident conditions involving the release of
hazardous materials into the environment?
c) Emit hazardous emissions or handle hazardous or acutely hazardous
materials, substances, or waste within one-quarter mile of an existing or
proposed school?
d) Be located on a site which is included on a list of hazardous materials sites
compiled pursuant to Government code Section 65962.5 and, as a result,
would it create a significant hazard to the public or the environment?
e) For a project located within an airport land use plan or, where such a plan has
not been adopted, within two miles or a public airport or public use airport,
would the project result in a safety hazard for people residing or working in the
project area?
f) For a project within the vicinity of a private airstrip, would the project result in
a safety hazard for people residing or working in the project area?
g) Impair implementation of or physically interfere with an adopted emergency
response plan or emergency evacuation plan?
h) Expose people or structures to a significant risk of loss, injury or death
involving wildland fires, including where wildlands are adjacent to urbanized
areas or where residences are intermixed with wildlands?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The project will not create a significant hazard to the public through the transport, use, or
disposal of hazardous materials, nor are there reasonably foreseeable upset and accident
conditions at the property. In addition, construction and residential uses would not emit
hazardous emissions within a quarter mile of an existing or proposed school. The Navy
conveyed the property in 2002 as unrestricted and suitable for residential reuse.
In addition, the project site is located within the boundaries of the Airport Environs Land
Use Plan; however, it is at least four (4) miles from John Wayne Airport, and does not lie
within a flight approach or departure corridor and thus does not pose an aircraft -related
safety hazard for future residents or workers. The project site is also not located in a
wildland fire danger area. Compliance with all federal, state and local regulations
concerning handling and use of household hazardous substances will reduce potential
impacts to below a level of significance. No substantial change is expected from the
analysis previously completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with

regard to hazards and hazardous materials. Specifically, there have not been: (1)
changes to the Project that require major revisions of the previous FEISIEIR due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; (2) substantial changes with respect to the
circumstances under which the Project is undertaken that require major revisions of the
previous FEISIEIR due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.
Mitigation/Monitoring Required: As identified in the FEISIEIR, compliance with existing rules
and regulations would avoid the creation of potential impacts. No mitigation is required.

VIII. HYDROLOGY AND WATER QUALITY: - Would the project:
a) Violate any water quality standards or waste discharge requirements?
b) Substantially deplete groundwater supplies or interfere substantially with
groundwater recharge, such that there would be a net deficit in aquifer volume
or a lowering of the local groundwater table level (e.g., the production rate of
pre-existing nearby wells would drop to a level which would not support
existing land uses or planned uses for which permits have been granted)?
c) Substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river, in a manner which
would result in flooding on- or off-site?
d) Substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river, or substantially
increase the rate or amount of surface runoff in a manner, which would result
in flooding on- or off-site?
e) Create or contribute runoff water which would exceed the capacity of existing
or planned storm water drainage systems or provide substantial additional
sources of polluted runoff?
f) Otherwise substantially degrade water quality?
g) Place housing within a 100 -year flood hazard area as mapped on a federal
Flood hazard Boundary of Flood Insurance Rate Map or other flood hazard
delineation map?
h) Place within a 100 -year flood hazard area structures, which would impede or
redirect flood flows?
i) Expose people or structures to a significant risk of loss, injury or death
involving flooding, including flooding as a result of the failure of a levee or
dam?
j) inundation by seiche, tsunami, or mudflow?

The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The project design and construction of facilities to fully contain drainage of the site would be
required as conditions of approval of the project and submitted/approved Water Quality
Management Plan. No long-term impacts to hydrology and water quality are anticipated for
the proposed project. The proposed housing project will also not impact groundwater in the
deep regional aquifer or shallow aquifer. The proposed project would not include
groundwater removal or alteration of historic drainage patterns at the site. The project is
not located within a 100 -year flood area and will not expose people or structures to a
significant risk of loss, injury and death involving flooding as a result of the failure of a levee
or dam, nor is the proposed project susceptible to inundation by seiche, tsunami, or
mudflow.
Construction operations would be required to comply with the Total Maximum Daily Load
(TMDL) for the Newport Bay watershed that requires compliance with the Drainage Area
Master Plan (DAMP) and National Pollution Discharge Elimination System (NPDES) and
the implementation of specific best management practices (BMP). Compliance with state
and local regulations and standards, along with established engineering procedures and
techniques, would avoid unacceptable risk or the creation of significant impacts related to
such hazards. Consequently, no substantial change is expected from the analysis
previously completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to hydrology and water quality. Specifically, there have not been: (1) changes to

substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.

IX. LAND USE AND PLANNING: Would the project:
a) Physically divide an established community?
b) Conflict with any applicable land use plan, policy, or regulation of an agency
with jurisdiction over the project (including, but not limited, to the general
plan, specific plan, local coastal program, or zoning ordinance) adopted for the
purpose of avoiding or mitigating an environmental effect?
c) Conflict with any applicable habitat conservation plan or natural community
conservation plan?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable Medium -High Density residential apartment units (88 very low income, 73
low income, and 64 moderate income). The proposed use is consistent with the
approved Specific Plan, and the number of dwelling units proposed by the Project is
under the maximum development threshold for Planning Area 15, which contemplates
the development of 1214 dwelling units in total. The City of Tustin is the controlling
authority over implementation of the Reuse Plan for the former base, such as land use
designations, zoning categories, recreation and open space areas, major arterial roadways,
urban design, public facilities, and infrastructure systems. On February 3, 2003, the Tustin
City Council approved the Specific Plan for MCAS Tustin that established land use and
development standards for development of the site. The proposed project complies with
Planning Area 15's development standards for multiple family residential units as noted in
Sections 3.9.2.G of the MCAS Tustin Specific Plan. The City must support density bonus
requests, concessions or incentives when projects provide affordable housing units in
compliance with California Government Code Section 65915(1), as authorized under
Tustin City Code Section 9123. Compliance with state and local regulations and
standards would avoid the creation of significant land use and planning impacts. Also, the
proposed project will not conflict with any habitat conservation plan or natural community
conservation plan. Consequently, no change is expected from the analysis previously
completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to land use and planning. Specifically, there have not been: (1) changes to the
Project that require major revisions of the previous FEISIEIR due to the involvement of
new significant environmental effects or a substantial increase in the severity of
previously identified effects; (2) substantial changes with respect to the circumstances
under which the Project is undertaken that require major revisions of the previous
FEISIEIR due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.
Mitigation/Monitoring Required: The proposed project is consistent with the development
standards of the MCAS Tustin Specific Plan as identified by the adopted FEISIEIR. No
mitigation is required.

X. MINERAL RESOURCES: Would the project:
a) Result in the loss of availability of a known mineral resource that would be a
value to the region and the residents of the state?
b) Result in the loss of availability of a locally important mineral resource
recovery site delineated on a local general plan, specific plan or other land use
plan?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
Chapter 3.9 of the FEISIEIR indicates that no mineral resources are known to occur
anywhere within the Reuse Plan area. The proposed project will not result in the loss of
mineral resources known to be on the site or identified as being present on the site by any
mineral resource plans. Consequently, no substantial change is expected from the
analysis previously completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to mineral resources. Specifically, there have not been: (1) changes to the Project
that require major revisions of the previous FEISIEIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously

the Project is undertaken that require major revisions of the previous FEISIEIR due to
the involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; or (3) the availability of new information of
substantial importance relating to significant effects or mitigation measures or

XI. NOISE: Would the project:
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?
b) Exposure of persons to or generation of excessive ground borne vibration or
ground borne noise levels?

Page 15
c) A substantial permanent increase in ambient noise levels in the project vicinity
above levels existing without the project?
d) A substantial temporary or periodic increase in ambient noise levels in the
project vicinity above levels existing without the project?
e) For a project located within an airport land use plan or, where such a plan has
not been adopted, within two miles of a public airport or public use airport,
would the project expose people residing or working in the project area to
excessive noise levels?
Q For a project within the vicinity of a private airstrip, would the project expose
people residing or working in the project area to excessive noise levels?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The proposed project could result in implementation activities that generate noise. The
FEISIEIR indicates that full build -out of the base will create noise impacts that would be
considered significant if noise levels experienced by sensitive receptors would exceed
those considered "normally acceptable" for the applicable land use categories in the Noise
Elements of the Tustin General Plan. The applicant has submitted a Noise Impact Study
for the project that indicates that additional mitigation will not be required (Source: see
Exhibit 1). However, the City of Tustin will ensure that construction activities comply with
the City's Noise Ordinance and that the proposed multi -family housing units are designed
with adequate noise attenuation (i.e., window design, sound walls) to meet the allowable
noise levels as required by Tustin City Code for residential use. The project would be
sound attenuated against present and projected noise so as not to exceed an exterior noise
standard of 65 dB CNEL in outdoor living areas and an interior standard of 45 dB CNEL in
all habitable rooms to reduce noise -related impacts to a level of insignificance. Compliance
with adopted mitigation measures and state and local regulations and standards, along with
established engineering procedures and techniques, will avoid unacceptable risk or the
creation of significant impacts related to such hazards.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to noise. Specifically, there have not been: (1) changes to the Project that require
major revisions of the previous FEISIEIR due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously identified
effects; (2) substantial changes with respect to the circumstances under which the
Project is undertaken that require major revisions of the previous FEISIEIR due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; or (3) the availability of new information of
substantial importance relating to significant effects or mitigation measures or
alternatives that were not known and could not have been known when the 1=EISIEIR,
the Supplemental or Addendum were certified as completed.
Mitigation/Monitoring Required Mitigation measures have been adopted by the Tustin City
Council in the FEISIEIR; these measures would be included as conditions of approval for
the project.

XII. POPULATION & HOUSING: Would the project:
a) Induce substantial population growth in an area, either directly (for example,
by proposing new homes and businesses) or indirectly (for example, through
extension of roads or other infrastructure)?
b) Displace substantial numbers of existing housing, necessitating the
construction of replacement housing elsewhere?
c) Displace substantial numbers of people, necessitating the construction of
replacement housing elsewhere?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan, and
the number of dwelling units proposed by the Project is under the maximum
development threshold for Planning Area 15, which contemplates the development of
1214 dwelling units in total_ The City must support density bonus requests, concessions
or incentives when projects provide affordable housing units in compliance with
California Government Code Section 65915(1), as authorized under Tustin City Code
Section 9123. Additionally, the proposed project site is vacant and will not displace people
or necessitate construction of replacement housing elsewhere. No substantial change is
expected from the analysis previously completed in the FEISIEIR for MCAS Tustin.
Based on the foregoing, none of the conditions identified in CEQA Guidelines Section
15162 that would trigger the need to prepare a subsequent or supplemental EIR or other
environmental document to evaluate Project impacts or mitigation measures exist with
regard to population and housing. Specifically, there have not been: (1) changes to the
Project that require major revisions of the previous FEISIEIR due to the involvement of

XIII. PUBLIC SERVICES
a) Would the project result in substantial adverse physical impacts associated
with the provision of new or physically altered governmental facilities, need for
new or physically altered governmental facilities, the construction of which
could cause significant environmental impacts, in order to maintain acceptable
service ratios, response times, or other performance objectives for any of the
public services:
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The site is currently vacant. Development of the site would require public services such as
fire and police protection services, schools, libraries, recreation facilities, and biking/hiking
trails.
Fire Protection. The proposed project will be required to meet existing Orange County
Fire Authority (OCFA) regulations regarding demolition, construction materials and
methods, emergency access, water mains, fire flow, fire hydrants, sprinkler systems,
building setbacks, and other relevant regulations. Adherence to these regulations would
reduce the risk of uncontrollable fire and increase the ability to efficiently provide fire
protection services to the site. The number of fire stations existing and planned in the
area surrounding the site will meet the demands created by the proposed project.
Police Protection. The need for police protection services is assessed on the basis of
resident population estimates, square footage of non-residential uses, etc. Development of
the site would increase the need for police protection services. The developer as a
condition of approval for the project would be required to work with the Tustin Police
Department to ensure that adequate security precautions such as visibility, lighting,
emergency access, address signage are implemented in the project at plan check.
Schools. The proposed project is located within Tustin Unified School District (TUSD).
The implementation of the Reuse Plan would provide two 10 -acre sites for elementary
schools and a 40 -acre high school site to serve the growing student population within its
district. Based on the student generation factors of 0.29 per unit for grades K-5; 0.127
student per units for grades 6-8; 0.153 student per unit for grades 9-12, and the potential
of 2,585 dwelling units developed within the TUSD boundaries, the adopted EIS/EIR
noted that reuse development would generate approximately 750 students for grades K-
5, 328 students for grades 6-8, and 395 students for grades 9-12 for a total of 1,473
students.
The total number of units approved in the Specific Plan for Neighborhood G is 2,383
units; the total number of units approved in the Specific Plan for Planning Area 15 is
1214 The applicant is requesting approval of 225 units (representing 9% of the total
number of units allowed in Neighborhood G, and 18% of the total units allowed in
Planning Area 15). No other residential units have been previously built in Planning
Area 15. The TUSD will receive its statutory school impact fees per Senate Bill 50 from
the proposed residential development of the site. As a condition of approval for the
project, the developer will be required to pay applicable school fees prior to issuance of
the building permit. In summary, no new additional students are anticipated beyond
what was considered in the FEIRIEIS for the Disposal and Reuse of MCAS, Tustin, and
in any event, City required mitigation is limited by State law to requiring payment of the
SB 50 school impact fees.

Other Public Facilities (Libraries). Implementation of the entire Reuse Plan would only
result in a library demand of up to approximately 2,500 square feet of library space. This
relatively small amount of space is well below the library system's general minimum size of
10,000 square feet for a branch library and would not trigger the need for a new facility.
General Implementation Requirements: To support development in the reuse plan area, the
Reuse Plan/Specific Plan requires public services and facilities to be provided concurrent
with demand. The proposed project will be required to comply with FEISIEIR
implementation measures adopted by the Tustin City Council.
No substantial change is expected from the analysis previously completed in the approved
FEISIEIR for MCAS Tustin. Based on the foregoing, none of the conditions identified in
CEQA Guidelines Section 15162 that would trigger the need to prepare a subsequent or
supplemental EIR or other environmental document to evaluate Project impacts or
mitigation measures exist with regard to public services. Specifically, there have not
been: (1) changes to the Project that require major revisions of the previous FEISIEIR
due to the involvement of new significant environmental effects or a substantial increase
in the severity of previously identified effects; (2) substantial changes with respect to the
circumstances under which the Project is undertaken that require major revisions of the
previous FEISIEIR due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.
Mitigation/Monitoring Required. Mitigation measures have been adopted by the Tustin City
Council in the FEISIEIR; these measures would be included as conditions of approval for
the project.

XIV. RECREATION
a) Would the project increase the use of existing neighborhood and regional
parks or other recreational facilities, such that substantial physical
deterioration of the facility would occur or be accelerated?
b) Does the project include recreational facilities or require the construction or
expansion of recreational facilities, which might have an adverse physical
effect on the environment?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Pian.
The project includes improvement of an adjacent, 4.706 acre neighborhood park that will be
available to the public.

Since the Reuse Plan process included public conveyance of city parks and an Urban
Regional Park, individual developers were relieved of the requirement to dedicate land for
park purposes. However, pursuant to the MCAS Tustin Specific Plan, the developers are
required to provide in -lieu fees or public accessible park space (where approved by the
City). Projects that do not propose the subdivision of property are exempt from the
provisions of the Quimby Act. In addition, the Disposition and Development Agreement
between the City and the developer will require that the private developer will improve the
adjacent park site.
No substantial change is expected from the analysis previously completed in the approved
FEISIEIR for MCAS Tustin. Based on the foregoing, none of the conditions identified in
CEQA Guidelines Section 15162 that would trigger the need to prepare a subsequent or
supplemental EIR or other environmental document to evaluate Project impacts or
mitigation measures exist with regard to recreation. Specifically, there have not been: (1)
changes to the Project that require major revisions of the previous FEISIEIR due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; (2) substantial changes with respect to the
circumstances under which the Project is undertaken that require major revisions of the

substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.

XV. TRANSPORTATION/TRAFFIC: Would the project:
a) Cause an increase in traffic, which is substantial in relation to the existing
traffic load and capacity of the street system (i.e., result in a substantial
increase in either the number of vehicle trips, the volume to capacity ratio on
roads, or congestion at intersections)?
b) Exceed, either individually or cumulatively, a level of service standard
established by the county congestion management agency for designated
roads or highways?
c) Result in a change in air traffic patterns, including either an increase in traffic
levels or a change in location that result in substantial safety risks?

d) Substantially increase hazards due to a design feature (e.g., sharp curves or
dangerous intersections) or incompatible uses (e.g., farm equipment)?
e) Result in inadequate emergency access?

The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan, and
the number of dwelling units proposed by the Project is under the maximum
development threshold for Planning Area 15, which contemplates the development of
1214 dwelling units in total. The FEISIEIR indicates that transportation and circulation
impacts would be created through the phased development of the approved Reuse Plan
and MCAS Tustin Specific Plan. A projected 216,445 Average Daily Trips (ADT) would
be generated by full redevelopment of the base by year 2020 that, if left unmitigated,
would overburden existing roadways and intersections surrounding the base property.
The FEISIEIR indicates that traffic circulation activities at MCAS Tustin generated a
baseline of 12,400 ADT when the base was fully operational (1993). As a military facility,
the FEISIEIR considered the traffic impact and developed a mitigation program to reduce
potential impacts to a level of insignificance. This site will be conditioned to participate in its
fair share responsibility for both on-site and off-site circulation mitigation and
implementation measures. In addition, construction activities are required to be meet all
Transportation related FEISIEIR Implementation and Mitigation Measures (e.g., lane
closures, street/utility construction, construction vehicle traffic, etc.). The FEISIEIR
implementation and mitigation measures will reduce potential impacts to the traffic and
circulation system to a level of insignificance. In addition, certain public infrastructure is
required to be constructed by the developer as a requirement of the DDA. Also, a parking
assessment and gate design analysis was submitted by the applicant which indicates that
the project will not adversely impact parking and circulation within or outside the project
area (See Exhibit 2). Consequently, no substantial change is expected from the analysis
previously completed in the approved FEISIEIR for MCAS Tustin.
No substantial change is expected from the analysis previously completed in the approved
FEISIEIR for MCAS Tustin. Based on the foregoing, none of the conditions identified in
CEQA Guidelines Section 15162 that would trigger the need to prepare a subsequent or
supplemental EIR or other environmental document to evaluate Project impacts or
mitigation measures exist with regard to traffic. Specifically, there have not been: (1)
changes to the Project that require major revisions of the previous FEISIEIR due to the
involvement of new significant environmental effects or a substantial increase in the
severity of previously identified effects; (2) substantial changes with respect to the
circumstances under which the Project is undertaken that require major revisions of the
previous FEISIEIR due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified effects; or (3) the availability
of new information of substantial importance relating to significant effects or mitigation
measures or alternatives that were not known and could not have been known when the
FEISIEIR, the Supplemental or Addendum were certified as completed.

Council in the FEISIEIR; these measures would be included as conditions of approval for
the project.

XVI. UTILITIES AND SERVICE SYSTEMS: Would the project:
a) Exceed wastewater treatment requirements of the applicable Regional Water
Quality Control Board?
b) Require or result in the construction of new water or wastewater treatment
facilities or expansion of existing facilities, the construction of which could
cause significant environmental effects?
c) Require or result in the construction of new storm water drainage facilities or
expansion of existing facilities, the construction of which could cause
significant environmental effects?
d) Have sufficient water supplies available to serve the project from existing
entitlements and resources, or are new or expanded entitlements needed?
e) Result in a determination by the wastewater treatment provider, which serves
or may serve the project that it has adequate capacity to serve the project's
projected demand in addition to the provider's existing commitments?
f) Be served by a landfill with sufficient permitted capacity to accommodate the
project's solid waste disposal needs?
g) Comply with federal, state, and local statutes and regulations related to solid
waste?
The proposed development of Disposition Package 1A -North would include a total of
225 affordable residential apartment units (88 very low income, 73 low income, and 64
moderate income). The proposed use is consistent with the approved Specific Plan.
The FEIRIEIR analyzed medium-high residential development on the proposed site,
which is consistent with the proposed project. Development of the site would require on-
site improvements and off-site infrastructure improvements to utilities and roadway
systems, including design and construction of full width improvements on Tustin Ranch
Road, Legacy Road and Park Avenue. In addition, certain public infrastructure will be
constructed by the applicant which may include storm drain, domestic water, reclaimed
water, sanitary sewer, and dry utility service systems necessary to serve the site, and
landscape and irrigation on in the public right-of-way. In addition, development of the
site is required to meet federal, state, and local standards for design of wastewater
treatment. The number of proposed units can be supported by the Irvine Ranch Water
District for domestic water and sewer services.
No substantial change is expected from the analysis previously completed in the approved
FEISIEIR for MCAS Tustin. Based on the foregoing, none of the conditions identified in
CEQA Guidelines Section 15162 that would trigger the need to prepare a subsequent or
supplemental EIR or other environmental document to evaluate Project impacts or
mitigation measures exist with regard to utilities and service systems. Specifically, there
have not been: (1) changes to the Project that require major revisions of the previous
FEISIEIR due to the involvement of new significant environmental effects or a

XVII. MANDATORY FINDINGS OF SIGNIFICANCE
a) Does the project have the potential to degrade the quality of the environment,
substantially reduce the habitat of a fish or wildlife species, cause a fish or
wildlife population to drop below self-sustaining levels, threaten to eliminate a
plant or animal community, reduce the number or restrict the range of a rare or
endangered plant or animal or eliminate important examples of the major
periods of California history or prehistory?
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?
Based upon the foregoing, the proposed project does not have the potential to degrade the
quality of the environment, substantially reduce the habitats or wildlife populations to
decrease or threaten, eliminate, or reduce animal ranges, etc. With the enforcement of
FEISIEIR mitigation and implementation measures approved by the Tustin City Council, the
proposed project does not cause unmitigated environmental effects that will cause
substantial effects on human beings, either directly or indirectly. In addition, the proposed
project does have air quality impacts that are individually limited, but cumulatively
considerable when viewed in connection with the effects of the reuse and redevelopment of
the former MCAS Tustin. The FEISIEIR, the Supplemental and Addendum previously
considered all environmental impacts associated with the implementation of the Reuse
Plan and MCAS Tustin Specific Plan. The project proposes no substantial changes to
environmental issues previously considered with adoption of the FEISIEIR. Mitigation
measures were identified in the FEIS/E1R to reduce impact but not to a level of
insignificance. A Statement of Overriding Consideration for the FEISIEIR was adopted by
the Tustin City Council on January 16, 2001.

CONCLUSION
The summary concludes that all of the proposed project's effects were previously examined in the
FEISIEIR 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. A Mitigation and Monitoring and Reporting Program and Findings of Overriding
Considerations were adopted for the FEISIEIR on January 16, 2001 and shall apply to the
proposed project, as applicable.

1.0 SUMMARY
This report documents the impact of road, rail and air traffic noise on the proposed Tustin Legacy
multifamily housing in the City of Tustin. Because the proposed apartments are part of the Marine
Core Air Station (MCAS) Redevelopment Project, few roads exist on the site. Road traffic will be the
major sound source at the project site when complete. Other sound sources include commercial flights
into and out of John Wayne Airport, heavy rail traffic to the north, activity at the commercial retail site
southwest of the project site and activity in the park to the east. The latter two sound sources are non -
transportation types. The heavy rail tracks are more than 3,000 feet away. John Wayne Airport is
approximately 2.5 miles southwest of the project site but departures are near the site. Road traffic is
expected to remain the dominant sound source at the project site to the design year of 2030. Sound
generated by activity in the park east of the site is expected to increase with time. Based on the pro-
posed layout, significant group activity is not expected to occur close to the common boundary. Sound
generated in the park will be heard and could become excessive at time. This is particularly true for
organized events or activities or for random individual events. Sound from commercial properties is
expected to increase slightly. The park and commercial property generate non -transportation sound
sources that are judged based on the hourly sound level. Sound reduction is difficult for both sources.
For park produced sounds, mitigation is limited to building sound walls at the common boundary,
monitoring park activity and restricting use near the boundary. The project will create non -transporta-
tion sources such as mechanical equipment, parking lot activity and general human activity. These are
not expected to adversely influence any nearby residential property. The project will generate road
traffic, but the day -night average, Lam, sound level will increase by less than 0.5 dB(A). This is consid-
ered insignificant.
The project site is on the former MCAS and includes a multi -family residential development and
the development of a park adjacent to it, to the northeast. The residential site is bounded by Tustin
Ranch Road on the west, Legacy Road on the north and Park Avenue on the east. Tustin Ranch Road
and Park Avenue exist, but not near the project site. Legacy will be a completely new street. All of
the 15 buildings will lie on Lot 20 and the park will occupy Lot MMM. Nine of the buildings will be
next to a street, one will be in the center of the other buildings, and five will be next to an adjacent
property or the park. All the apartment buildings will be three stories tall, except for the central build-
ing, which will be four stories.
Noise Requirements of City of Tustin are given in the Noise Element chapter of the City of Tust-
in General Plan [If and in the Noise Control chapter of the Health and Sanitation article of the City
of Tustin Code of Ordinances [2]. The California Building Code, CBC, [3] requires a noise study
when residential property is exposed to day -night average, L., sound level goal of 60 dB(A) or more
in outdoor activity areas. The City uses the Community Noise Equivalent Level, CNEL, as their met-
ric of choice for transportation sources. The CNEL divides the day into three parts, day, evening and
night with penalties for evening and night sound levels. The City sets an exterior La„ sound level limit
of 65 dB for multifamily residences in common recreation areas and patios or balconies of 6 feet or
more in depth. The CNEL is typically higher than the Ld, sound level, but by no more than 0.5 dB.
The City and the State have an interior L. sound level limit of 45 dB in habitable spaces such as bed-
rooms.
* - Number in brackets refers to references listed at the end of this letter report.
R12135: SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2012 A/ine
Existing plus project exterior L. sound levels are predicted to be 53 to 67 dB(A) when measured
at the buildings' exterior, on balconies, or in common recreation areas. Road traffic is the main source.
The impact of the change in exterior Ld., sound level from cumulative to cumulative plus project is
insignificant. The changes in all predicted exterior L. sound levels are at or less than 70 dB(A), and
less than 65 dB(A) in the common recreation areas or on the balconies, the impact is considered insig-
nificant. Additional exterior sound reduction is not required.
The cumulative plus project exterior Ld. sound levels were used to predict the interior L. sound
levels in habitable rooms closest to roadways. A 45 dB Ldn sound level design goal was used in the
evaluation of these spaces with the application of a 2 dB margin of safety. The margin of safety ac-
counts for inaccuracies in the model and the use of laboratory data that will not reflect field construc-
tion procedures and techniques. Interior Ld. sound levels will not exceed the City's 45 dB Criteria nor
the Design Goal of 43 dB(A). Predictions were done based on the proposed construction shown in the
architectural drawings [4]. Interior L. sound level impacts will be insignificant relative to the City's
limit and the design goal. Special mitigation measures will not be required but certain minimums
material and construction techniques must be followed to comply with the assumption used in arriving
at these conclusions.
Non -transportation sound sources associated with the park could produce levels that exceed the
City's Noise Ordinance. The park is not set up for organized athletics or concerts and sound reinforce-
ment systems will not be allowed. The park has been designed maximize the distance between picnic
areas and play areas and the boundary common to the apartments. Spontaneous or unorganized events
such as birthday parties could generate excess sound if held close to the common boundary. Ideally,
people should be encouraged to hold such events in the designated areas and to be within 50 feet of the
common boundary during such gathers. The design allows visual access between the multifamily
dwellings and the park and a gate at one location allows access from the apartments. The proposed
wall separating the two uses provides both visual and acoustical views between the park and the apart-
ments. That is, the wall not stop people from looking into the opposite area and neither will it stop
sound from passing back and forth. Administrative action should be pursued first to prevent excess
sound generation by designing the areas closest to the common boundary to prevent any gatherings. If
a problem persists with excess sound from the park, building a sound wall along the common boundary
could be an option. This would only be undertaken after tests show that the City's limits are exceeded
and administrative options have been exhausted.
2.0 ACOUSTIC STANDARDS
Noise sensitive projects fall under the jurisdiction of two sets of acoustical criteria as published
by the City of Tustin. The first criterion is given in the Noise Element chapter of the City of Tustin
General Plan [l ]. The second standards are contained in the Noise Control chapter of the Health and
Sanitation article of the City of Tustin Code of Ordinances [2]. These are described below.
2.1 Noise Element Standards
Acoustic criteria contained in the Noise Element of the City of Tustin General Plan are based on
the Community Noise Equivalent Level, CNEL, sound level. This criterion addresses the average
sound Ievel over 24 -hours and is directed mainly at transportation sources. Table N-3 of the Noise
Elements sets an interior noise limit is CNEL 45 dB and the exterior noise limit is CNEL 65 dB. The
interior noise standard is with windows closed. For multifamily residences, the exterior requirement
2
R12135: SAP, Nis and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2012 Alone
applies on patios and balconies with a depth of b feet or more and in common recreation areas. For the
purpose of this project, common recreation areas are the courtyards of Buildings 8 and 4 and the recre-
ation/pool area.
Both the CNEL and L�„ metrics address the average sound level over 24 -hours and are directed
mainly at transportation sources. The day -night noise descriptor averages measured or predicted sound
levels over 24 -hours after applying a 10 dB penalty to nighttime sounds. Hourly average sound Ievels,
L.q, are measured or predicted for each hour of the day or for each hour during which a sound source is
present. A 10 dB penalty is added to each hourly average sound level measured or predicted from
10:00 p.m. to 7:00 a.m. The penalty is applied because people trying to sleep during these hours are
more sensitive to external sounds. The CNEL divides the day into three parts instead of two. Daytime
is defined as 7:00 a.m. to 7:00 p.m. while the evening is the hours between 7:00 p.m. to 10:00 p.m.
The same nighttime penalty is applied for the CNEL but the evening has a 5 dB penalty for sound
measured during these hours. The 10 dB nighttime penalty is equivalent to multiplying the number of
train, plane or road "events" by 10. That is, the volume is increased by a factor of 10. The evening
penalty used by the CNEL is equivalent to multiplying the number of "events" by 3. Typically, the
CNEL is about 0.5 dB(A) higher than the L� sound level at any site. This is within the prediction
error for these metrics. However using the CNEL is difficult for many sources because there is no
specific information for 7:00 p.m. to 10:00 p.m. Therefore, the day -night average, L., is used instead
for many sources such as road traffic. Excluding or including only certain sources is possible. For
example, the sounds of aircraft flying over the site are included only during those hours when they
occur. If no events happen during the nighttime, no penalty would be applied. When some sources are
excluded from the analysis, it is called the Background L. or CNEL sound level.
2.2 Noise Control Ordinance
The second criteria, the Noise Ordinance [23, looks at the sound produced during shorter times by
sources not related to transportation equipment. The one exception is that sound produced by trans-
portation equipment while on private property may be regulated by the Noise Ordinance. This Ordi-
nance limits the amplitude and duration of sound produced over any given I -hour period. Sound limits
are based on the type of source, the duration of the sound, the time of day of occurrence, background
sound levels and the tonal content of sound. This is a City code and is enforceable with limited excep-
tions. The Noise Control Ordinance applies a 5 dB penalty to the limits when the sound comprises
mainly speech or music or if it contains pure tones or impact sounds. When background sound levels
equal the limits given in Table I for the individual categories, the limit of that category is raised to
reflect the background sound. The exact meaning of this is unclear. Table I summarizes limits of the
Noise Ordinance with and without a penalty but without regard to the background sound level. The
background sound level is that measured when the source or sources of interest are absent. Sound
generated at the project by people or mechanical equipment will be required to meet limits of the Noise
Ordinance at all nearby residential property. Sound generated at the park will be required to meet
these limits at the multifamily development.
The City also has a sound level limit for the interior of multifamily units. Again, the limits are
based on the sound measured over an hour. This standard is believed to apply to sources within adja-
cent units and for sources exterior to the building. Penalties apply for time of day and sound character-
istic. The influence of background sound on the limits is the same as for the exterior. Table II pro-
vides a summary of the interior noise standards for non -transportation sound sources.

3.0 PROJECT DESCRIPTION & SITE
The project site is on an undeveloped plot of land that was part of a Marine Corps Air Station.
The property has been turned over to the City of Tustin for redevelopment. The infrastructure will
have to be installed before residential development can begin. A 12.2 acre parcel that is to be bor-
dered on the west by Tustin Ranch Road, on the north by Legacy Road, and on the east by Park Ave-
nue in the MCAS redevelopment project (Lots 20 and MMM of tract number 17404 [5]) is proposed to
be developed for affordable multifamily housing (7.49 acres) and a park (4.71 acres). A total of 225
units is to be constructed at the site in 14 3 -story buildings and one 4 -story building. The latter build-
ing includes the rental offices, club room, and fitness facilities as well as several apartments on the
ground floor. Four of the buildings front Park Avenue, three front Tustin Ranch Road, one is on the
corner of Tustin Ranch Road and Legacy Road, one fronts Legacy Road, one fronts an adjacent Iot
(Lot 21), four front the park, and one is in the center of the other buildings.
All land that is part of the MCAS redevelopment project is currently vacant. Single-family
homes may be built on land surrounding the project site but at this time no land uses are confirmed.
Southwest of the project is an existing commercial retail center bordered on the north by the existing
4
RI 2135: SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2012 T
section of Tustin Ranch Road and an existing section of Warner Avenue. The Google Earth program
suggests that the property is currently about 45 to 47 feet above seal level (ASL) while the Tustin Leg-
acy civil engineering grading plans suggest that the finish floor elevations will range from 52 to 57 feet
ASL. The land will be fairly flat at the project site when complete.
Four basic apartment building designs are to be built with nine basic apartment layouts. All
apartments have 9 foot ceilings. The 3 -story buildings are designated at Types A (10), B (2), and C
(2). The 4 -story building is D and is the apartments cum recreation and rental office building in the
center of the development. Only four of the nine apartment layouts are evaluated as representative of
the worst case scenarios for this study. A typical exterior wall construction comprises 1 -coat stucco
over wire mesh, fastened to 1" thick insulation applied over 2 -layers of building paper fastened to
7/16" shear plywood attached to minimum 2" x 4" wood studs. R -I l insulation is to be installed in all
stud cavities with 5/8" Type X gypsum board attached to the interior face of the studs. The ceilings of
all living units will be finished with gypsum board. Double glazed windows will be used throughout
all units.
4.0 SOUND SOURCES
4.1 Existing
The proposed development is part of the Marine Core Air Station redevelopment project. None
of this land tract has been developed at this point. This includes a lack of roads on the property. Cur-
rently, Tustin Ranch Road borders a commercial retail center southwest of the project site but does not
continue onto the MCAS redevelopment land. Once roads are built on the MCAS redevelopment site,
road traffic on Tustin Ranch Road, Legacy Road, and Parr Avenue will be the dominant sound source
influencing the project site. Other sound sources are secondary in importance and include aircraft
flyovers, heavy rail traffic, dogs barking and general human activity.
Railroad tracks exist just north of Edinger Avenue, which forms the north border of the MCAS
redevelopment lands. These tracks are approximately 3,900 feet from the proposed project site. The
volume of traffic on the tracks is unknown. Table III provides the assumptions made regarding vol-
ume, number of engines, speed and percent of nighttime traffic.

John Wayne Airport in Irvine is approximately 2.5 miles southwest of the project site. The main
runway runs approximately southwest to northeast. Typical flight patterns carry the aircraft north of
the project site. The site is outside any standard noise contours generated by airport operations. The
airport maintains noise level monitoring sites including three north of the airport ($N, 9N, ION) [6].

R12135: SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2812 A/9W_
Sites 8N and ION are generally in line with the runway while 9N is offset to the west. This project site
is offset to the east further than 9N is to the west, so 2010 published aircraft noise levels for site 9N
were used to estimate the noise impact on the proposed project from John Wayne Airport. Standard
noise levels for heavy rail traffic moving through urban areas at the same distance were used to predict
the sound impacts on the proposed project site from the railroad traffic.
4.2 Existing + Project
Once roads are built on the MCAS redevelopment property, road traffic will be the dominant
sound source on the project site. Tustin Ranch Road will have 2 -lanes running each direction along
the west border of the property. Legacy Road will have a single lane running along the north border of
the property of both the apartment complex and the park. Park Avenue also will have a single lane
running along the east border of the property of both the apartment complex and the park. Road traffic
counts were based on data in Volume 2 of the Final Environmental Impact StatementlEnvironmental
Impact Report for the Disposal and Reuse of MCAS Tustin, FEIS/EIR [7]. This document provided
2005 and 2020 counts. The project has not started so the 2012 volumes were assumed to be the same
as for 2005 since the project has not progressed. Legacy Road was not included in the redevelopment
FEISIEiR. The road was assumed to be the Sam as Park Avenue. Table 1V summarizes the data used
to model the existing plus project Lda sound levels.

Rail and air traffic are not expected to change from existing to existing plus project. The infor-
mation given in the section on Existing Sound sources was used to find the exiting plus project L,
sound level.
4.3 Cumulative + Project
Road traffic on Tustin Ranch Road, Legacy Road and Park Avenue are expected to remain the
dominant sound source at the Tustin Legacy Apartments in the year 2030. Traffic generated by the
project will have a small impact on the total volume on these roads because the developments on the
other lots on Tract 17404 are expected to be built at approximately the same time as the proposed pro-
ject. Train movements and aircraft flights will remain sound sources of secondary importance. Very
little change is expected in the volume of traffic for these sources. The information in the section on
Existing sound sources will be applicable. Other secondary sound sources will include general avia-
tion flights, mechanical equipment and general human activity. Only vehicle volumes could be quanti-
fied.

R12135. SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, Augusl 28, 2012 TMe
The project will potentially be impacted by non -transportation sound sources and will impact
other residential areas because of such sources. The project will add new non -transportation sound
sources including mechanical equipment, trash collection, vehicle movements in the parking lot and
general human activity. Commercial sites southwest of the site are potential sources of non -transporta-
tion sound. This includes public address systems, mechanical equipment body work tools, people
talking, vehicles moving in and out of parking lots and other general activity. Activity in the park will
be another source of non -transportation sound. Adults and children playing or yelling could generate
excessive sound. In general, quantifying these sources is difficult.
Traffic volumes will grow from existing plus project to cumulative plus project conditions as
shown in the FEIS/EIR for the redevelopment project[7]. That environmental study was based on the
year 2005 as existing and 2020 for the cumulative plus project. Traffic volumes on Tustin Ranch Road
were projected to grow at an annual rate of 4 percent to the year 2020. An assumption was made that
the 2020 projected volumes were still applicable and faster growth would occur from 2012 to 2020 to
give these volumes. Between the year 2020 and 2030, road traffic was assumed to grow at an annual
rate of 1.5 percent on this road. Park Avenue traffic volumes were not expected to grow from 2005 to
2020 in the FEIS/EIR. Then, the volume was assumed to increase at an annual rate of 3 percent per
year to the year 2030. Legacy Road traffic volumes were not available but were assumed to be compa-
rable to those on Park Avenue. The same growth rates were used also. The traffic mix and speeds
were assumed to stay the same on all roads. A summary of road traffic information used to compute
cumulative plus project L. sound levels is given in Table V.

No changes were assumed in air and rail volumes or mixes to the year 2030. Information given

5.0 EXTERIOR ACOUSTIC ENVIRONMENT
5.1 Existing
As the MCAS redevelopment land is currently undeveloped, no measurements of existing sound
levels were made, nor were predictions of existing exterior sound levels completed. The existing
CNEL or L. sound levels are not important if there are no receivers to be impacted.
7
R12135: SAP, MS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2012 rho
5.2 Existing + Project
Predicted La„ sound levels due to road traffic were made using the Federal Highway Administra-
tion (FHWA) Highway Noise Prediction Model [8]. The FHWA model was modified to include the
CalTrans noise emission levels [9]. Road visibility and ground conditions were considered in calcula-
tions of the hourly average sound levels at the worst case position outside each apartment or outdoor
area considered. The ground was assumed to be acoustically hard for all vehicle types.
The day -night average sound levels were predicted at the project site based on the data given in
Table IV for road traffic and for other background sources. Exterior sound levels were predicted for
ten positions: seven for the exterior of the apartment walls, three for balconies, and two for common
outdoor areas. Predictions for the seven apartments were done at the exterior wall of each of the seven
evaluated apartments in what was determined to be the worst position for each. The courtyard and
pool were evaluated in what was determined to be the worst case spot in terms of exposure to road
noise. Three balconies were chosen, each representative of the worst case for each building. Accord-
ing to the Noise Element [I ], exterior noise standards have to be met in common recreation areas and
patios or balconies with a depth of six feet or more. This requirement means that exterior noise stan-
dards do not have to be met on the balconies of apartment floor plans 131, Cl, Al, or A2. Predictions
of the exterior Ld. sound level on the balconies were made for approximately three feet front the bal-
cony edge. Table VI gives the predicted day -night average sound levels for existing plus project con-
ditions at each of these nine positions.

R12135: SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2012 The
Existing plus project La„ sound levels do not exceed the 65 dB limit in the pool, courtyard, or any
of the three balconies. These are the areas of primary concern to which the Noise Element's exterior
noise standard applies. The exterior Ldn sound levels are not excessive at any of the buildings also.
5.3 Cumulative + Project
Road traffic is expected to remain the dominant sound source influencing the L. sound levels at
the project site to the year 2030. The FHWA model was used to predict the Ldp sound levels for road
traffic for cumulative plus project conditions using information in Table V. Though the number of
trains and planes is not expected to increase significantly, each of these was increased by 1 dB to ac-
count for the worst case scenario. Similarly, the other sound from other secondary sources was in-
creased by 2 dB to account for increased activity and varied land uses in the future. Table V1I presents
the predicted Ldp, sound levels at the same nine positions outside the seven apartments and in the Build-
ing 8 courtyard and pool area.

- John Wayne Airport sound levels are in CNEL rather than Ldn
* - Denotes outdoor areas to which the Noise Element's exterior noise standard applies
The predicted Ld, sound level for cumulative plus project conditions at the exterior varies from 56
to 70 dB(A). The Noise Element's 65 dB(A) noise standard applies to the two common recreation
areas and the three balconies. All of these spaces meet the noise standard, though the courtyard just
meets it with no safety factor. The exterior L. sound level at the face of the apartment reaches 70
dB(A).
Sound generated by people and animals using the park east/northeast of the Tustin Legacy apart-
ments could exceed the Noise Ordinance of the City. Predicting accurately sound levels for these
9
R12135: SAP, NIS and Recommendations to Meet Eloise Limits; Tustin Legacy Apts, August 28, 2012
sources is not possible without complete knowledge of the people using the park, what they are doing,
where are they doing and the time of day they are doing the activity. If a typical group activity occurs
near the west boundary of the park, the sound limits will likely be exceeded. Noise making activity
that occurs farther from this boundary will result in little or no impacts. Organized sporting or musical
events could result in excess sound at the residences, especially if a sound reinforcement system is
used.
6.0 INTERIOR ACOUSTIC ENVIRONMENT
The State of California assumes that a 15 dB reduction can be expected from the building exterior
to the building interior with the windows open. Thus, any Ld„ sound level greater than 64 dB will
cause interior sound levels to be greater than the 45 dB limit [1 ] if the windows or doors are allowed to
be open. The Noise Element specifies that the interior noise standard of CNEL 45 dB is with the win-
dows closed. The 45 dB limit with a 2 dB margin of safety was used to evaluate the wall construction
of the Tustin Legacy apartment buildings. A margin of safety is used because the highway noise pre-
diction model is only good to f1.5 dB(A) and because laboratory test data is used for construction
materials. The laboratory data is called the Sound Transmission Class, STC, ratings of building com-
ponents. Laboratory construction techniques can seldom be duplicated in the field. The State assumes
up to a 5 dB reduction in sound loss from the laboratory to the field. The STC rating of building prod-
ucts is used in the calculation of interior L� sound levels.
Interior Ld,, sound levels were predicted for bedrooms on the second floor that were closest to the
street. Interior Lm, sound levels are typically higher in smaller rooms, rooms with more than one exte-
rior wall, and rooms closest to Tustin Ranch Road which has the highest traffic volume and projected
speed. Because no sound measurements were made at the site, road traffic sound spectra measured at
another site with similar traffic volumes and speeds was used to calculate interior L. sound levels
based on the exterior Ld, sound level shown in Table VII. The wall construction described in the Pro-
ject Description Section was used in the prediction. A 5 dB reduction in the sound transmission was
assumed because of the source location outdoors with no reflecting surfaces nearby [ 10]. The sound
transmission loss of materials used in exterior constructions was taken from publications by the Na-
tional Institute of Tests and Standards [11] and the State of California [12]. Some data was taken from
literature published by manufacturers or computed from in house computer models.
Table VIII summarizes the predicted interior Ld„ sound levels for representative units closest to
each of the three roads. Exterior La„ sound levels shown in Table VII were used for these calculations.
Interior L� sound levels are all less than the 45 dB required by the City and less than the re-
quired level with a 2 dB(A) margin of safety. Sound impacts will be less than significant and mitiga-
tion measures are not required. The predicted results are true assuming the construction materials and
practices meet minimum requirements. These general requirements are described in the mitigation
section of this report.
The influence of road traffic on sleep interference and speech interference was evaluated also.
The maximum sound levels in bedrooms will be less than 50 dB(A). This will be sufficient to prevent
speech and sleep interference.

7.0 ACOUSTIC IMPACT
7.1 Exterior Impact
Exterior Ld„ sound level impacts for cumulative to cumulative plus project conditions due to
transportation sound sources are insignificant for multi -family residences. The noise impact due to the
absolute L. sound is insignificant because the predicted L. sound levels are at or less than 70 dB(A)
and because backyards do not exist. The Ld. sound level on the south side of the club house will be
less than 60 dB(A) and this was assumed to be the "backyard" for these units.
Sound levels produced by transportation and non -transportation sources associated with this pro-
ject could be significant. Sound reduction could be required, but too many unknowns exist. Both
administrative and physical sound reduction is possible.
7.2 Interior Impact
Interior La„ sound level impacts are insignificant for cumulative plus project conditions based on
the County's limit 45 dB in habitable spaces. Impacts are insignificant relative to the design goal of 43
dB and the maximum sound level. These conclusions are based on the proposed floor plans and con-
struction. All walls and windows must meet minimum acoustical requirements in all areas for these
conclusions to be correct.
8.0 MITIGATION MEASURES
Exterior sound reduction is not required for this project for transportation sources. Non -transpor-
tation sound generated in the park could have a significant impact. Options are included for providing
relief for such sources, but they would be implemented only if it is determined that a need exists for
such measures. Interior sound reduction is not needed to meet noise limits for transportation sound
11
RI 2135: SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 26, 2012 Aifte
sources. General acoustical requirements must be met for any of the conclusions to be accurate. The
general requirements are given in the following outline.
General Requirements
A. All joints in exterior walls shall be sealed airtight around windows and doors, at the wall
perimeter and at major seams.
B. All above ground penetrations of exterior walls by electrical and plumbing components shall
include a'/a to %2 inch airspace around the perimeter. This space shall be filled loosely with
fiberglass insulation. The space shall then be sealed airtight on both sides of the wall with a
resilient, non -hardening caulking or mastic.
C. Basic exterior wall construction for the main prayer hall shall include the following or an
equivalent:
1. Minimum 2" x 4" wood studs at a minimum 16 inches on center.
2. Minimum R-11 insulation in the stud cavities,
3. Minimum 518" Type X gypsum wallboard fastened to the interior face of the wood
studs. The wall shall be fully taped and finished including where perpendicular walls
intersect and where the wall meets the ceiling. The base of the walls shall be sealed
with a combination of backer rod and resilient, non -hardening caulking,
4. The exterior surface shall be finished with the following or with another product with
equal or greater surface weight.
a. Minimum 1 -layer of minimum 7/16" shear plywood with
b. 2 -layers of building paper fastened over plywood.
C. 1" thick dense insulation applied over building paper and fastened to studs or ply-
wood,
d. Minimum 20 gauge 1 " wire mesh, and
e. 1 -coat stucco over wire mesh,
D. Windows shall have a minimum STC rating of 29 or better. Windows shall have an air infil-
tration rate of less than or equal to 0.20 CFM/lin. ft. when tested with a 25 mile an hour
wind per ASTM standards. A good quality window with '/$" float glass, '/2" airspace,
float glass window should meet this requirement if the seals meet infiltration rates.
E. All exterior doors shall have a minimum STC rating of 29.
F. Sliding glass shall have a minimum STC 29 rating.
G. There shall be no need to open windows, doors or other exterior openings to provide ade-
quate ventilation.
Il. Non -transportation Sound Sources in Park
A. Administrative
1. Ensure park is closed for general use by 10:00 p.m.
2. Encourage people to gather at the picnic areas and playgrounds that are farther from
the residential boundary.
3. Design park to limit gatherings such as birthday parties from being within 50 feet of
the west property line.
12
R12135, SAP, NIS and Recommendations to Meet Noise Limits; Tustin Legacy Apts, August 28, 2012 rhe
4. Enforce the restriction on the use of sound reinforcement systems in the park and do
not allow the use of such equipment after 8:00 p.m or dusk, whichever comes first.
13. Physical Mitigation Measures (If administrative efforts are insufficient. Use only as a last
resort)
1. Construction a minimum 6 foot tall sound wall along the boundary between the apart-
ments and the park where the current combination solid and open wall is to be built.
2. Any such wall shall have a minimum surface density of 3.5 to 4 lbs./sq.ft.
3. The wall shall be continuous along its length and height with no gaps or holes.

Gate_Stackinr
The 4ite Klan prepared by Fu!(coe Engineering dated August 27 2012 shows that Anton
LegaL3 Apartments will share an access off' of Park Avenue with the future park see
Attaac.hmtnt l 111i:i aacc(.sti will ha a gated acct -ss with the entry/exit gates and call box
located past the future park parking drive aisles The gate stacking foi the proposed
apartment project is reviewed leased on the Count-, of Orange Standard Plan 1107 which is
one foot of stacking per dwelling unit Therefore, a minimum of 225 feet of stacking 19
required
All rt sidi.nt and gut st parking spaces foi the proposcd apartment project erre located inside
the gated area Hie re is an entry and exit gate; separated by a 5 foot raised center inedian
Roth the enntry and exit gates are 2 piece swing gates Rosidents will iceess the gate with
entry devices (remote) while guests will use the call box to gain enti-, The gates will tike
approxiinatel) 30 Seconds foi one full open L10se cycle but sensors will i -e 0en thL gates
when additional vehicles are detected it is anticipated that aaftei the mitril least- period
the gates will reinain closed during all hours In the event of a powei outage the gates will
nutomaatically swing open and stay open until pow(.i has becii restored The Lail box is
located approxnnately halt way between thL future. park drive aisles and the gate.') In
addition there is i turnaround area between the call box and the gates sere Atvichnient 1
The project dram provides full atcecs to the site and future pack and is approximately 10
feet wide at Park Avenue 11 feet wide at the call box and is feet at the gates (see
Attachment 1) The 10 foot wide cross section of the drn e consists of two inbound lanes and
two outbound lanes and a raised center median at the call box The inbound drive consists
of two 10 foot wide lanes at the entry and at the dill box that narrows down to a single 20
toot wide lane at the gate ['he raised inediaan at the call box 11, 5 feet wide The outbound
drive consists of one 13 font wide lane at the gate and one lei foot wide lane at the call box
that widens to one 10 foot «ide= shared through/left turn lane and a 10 foot wide right turn
lane Per Orange County Fire Authority (OCF 1) requirements the entry and exit lune at
the gatcs shall lx a miniMUM of 13 feet There is a secondary gated emergency vehicle
access west of the project drive along Paik Avenue but it will not be accessible b4 msidents
and guests The distance of the guest lane from the prolongation of the curb to the (.rill box
is 173 feet and the resident lane from the prolongation of the curb to the gate is 280 feet
The total stacking distance for both lanes is 453 feet which is more than the required 225

Conclusion
St Anton is proposing to develop the Anton Legaev Ipartnicnts in the City of Tustin N%ithin
the MCAS Tustin Specific flan circa The proposed 22.5 multifatnily dwelling units are
100% afford able and contain 1o1ALi MCO ltc untt.s, loN% incoinc. units, :ind moderate inc:onic
units The proposed pi-oject is pro%iding a total of 1,3,3 parking spades, which is less than the
-168 paiking spaces required by City of Tustin but inure than the 372 paiking spaces
required by State of( ialifornia fon affordable housing developments 5t Anton is requesting
the .applicAIDIi of the State packing requirements fol iaffordrablk housing developments
Therefore a parking accumulation -,tudy was conducted at two existing sinulat apartments
in the City of Irvine cin a wcc.kdav and one weekend day to establish the: observed parking
ratio The Woodbury %Valk Apartments and hlontecit.o Vista Apartmcnt5 art 100%
affordable and similar sired Based on the results of the study the average observed
parking ratio tot both sites is .1 2 spaces per dwelling units whish is significantly different
than the parking ratty calculated troni City requirements of 2 08 spiaccs per dx%cl.ling units
However, this compares: closely with the parkins; ratio calculated from the State parking
requirements of 1 6o spaces pet dwelling unit,, Applying the State pitrking requirements
will result in a total of 372 parkins; sp,lces Therefarc the proposed apartment project will
hw,e a surplus of 63 parking -spaces In addition tlae knit infix at the two existing
apartments suggest that more packing spaces arc required compared to Anton Denary
-'Apartments
A gate. stacking analysis was also conducted fon the :Anton Legacy Apartments brasc.d on the
County of Orange Standard Plan 1107 which is one foot of stacking per dwelling unit for a
total of 225 feet of stacking The separate entry and exit gates are 2 piece stip ing tater: with
sensors to rc� open the gates if additional vehicles are detected The inbound dive consists
of one 10 facet guest lane and one 10 foot restde.tlt lane. which narrows down to a Vit) foot
lane at the gate The distance of the guest lana Froin the: prolongation of the entrN curb is
