RESOLUTION NO. 4222 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF TUSTIN, CALIFORNIA APPROVING AN ADDENDUM TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT/ ENVIRONMENTAL IMPACT REPORT FOR THE DISPOSAL AND REUSE OF MCAS TUSTIN ( "FEIS /EIR ") FOR GENERAL PLAN AMENDMENT 2013- 001, MCAS TUSTIN SPECIFIC PLAN AMENDMENT 2013- 001 AND DEVELOPMENT AGREEMENT 2013 -002. The Planning Commission of the City of Tustin does hereby resolve as follows: The Planning Commission finds and determines as follows: A. That the City of Tustin ( "City ") and the South Orange County Community College District ( "SOCCCD ") propose a General Plan Amendment (GPA) 2013 -001 by adding a new local street (Bell Avenue) to service adjacent uses; MCAS Tustin Specific Plan Amendment (SPA) 2013 -001 by incorporating text allowing private for - profit non - educational uses and increase allowable building square footages within the education village (Neighborhood A) of the MCAS Tustin Specific Plan and adding a new local street (Bell Avenue); and Development Agreement (DA) 2013 -002 to facilitate the development, conveyance, and land exchange within the boundaries of the MCAS Tustin Specific Plan. B. That collectively, GPA 2013 -001, SPA 2013 -001, and DA 2013 -002 constitute a "project" that is subject to the terms of the California Environmental Quality Act ( "CEQA ") (Pub. Resources Code §21000 et. seq.). C. 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 April 3, 2006, the City Council adopted Resolution No. 06-43 approving an Addendum to the FEIS /EIR. 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. The FEIS /EIR along with its Addendum and Supplement is a program EIR under the California Environmental Quality Act (CEQA). The FEIS /EIR, Addendum and Supplement considered the potential environmental impacts associated with development on the former Marine Corps Air Station, Tustin. Resolution No. 4222 GPA 2013-001, SPA 2013-001, DA 2013-002 Page 2 D. An Environmental Checklist has been prepared and concluded that these actions do not result in any new significant environmental impacts or a substantial increase in the severity of any previously identified significant impacts in the FEIS/EIR. Moreover, no new information of substantial importance has surfaced since certification of the FEIS/EIR. However, because some changes and additions were required to the FEIS/EIR, the City has prepared an Addendum to the FEIS/EIR. The Planning Commission will consider the Addendum along with the FEIS/EIR prior to making a recommendation to the City Council on the GPA 2013-001, SPA 2013-001 and DA 2013-002. E. That pursuant to Sections 15051 and 15367 of the State CEQA Guidelines, the City is the Lead Agency for the CEQA compliance associated with the project because it will approve, carry out, and implement the project and will be the first agency to approve the project. SOCCCID will be a responsible agency. F. That an Addendum to the FEIS/EIR for the project is the appropriate CEQA documentation for the project because: a. The project does not change the land uses that are currently permitted within the MCAS Tustin Specific Plan, the impacts of which have been previously analyzed in the FEIS/EIR; b. The project would not permit an intensification of permitted uses that would lead to increased environmental impacts beyond those that are already identified in the FEIS/EIR; c. The project does not modify previously- analyzed projects in any substantive way; d. No new mitigation measures are required; e. None of the conditions identified in Public Resources Code Section 21166 or Section 15162 of the CEQA Guideless applies; and, f. No new significant adverse project-specific or cumulative impacts in any environmental areas were identified, nor would any project-specific or cumulative impacts in any environmental areas be made worse as a result of implementing the Project. G. Based on the initial study analysis and environmental checklist prepared for the Project and pursuant to Section 15162, 15163, 15164, and 15183 of the CEQA Guidelines, the City and SOCCCID have determined, on the basis of substantial evidence in the light of the whole record, that: m-WO Resolution No. 4222 GPA 2013-001, SPA 2013-001, DA 2013-002 Page 3 FIN a. The Project was examined in light of the FEIS/EIR and has been adequately analyzed in the FEIS/EIR because the Project does not substantively modify the previously-analyzed proposal included in the MCAS Tustin Specific Plan; b. The Project would not have any effects that were not already examined in the FEIS/EIR, no new mitigation measures are required, and there are no new significant adverse project- specific or cumulative impacts in any environmental areas that were identified, nor would any project-specific or cumulative impacts in any environmental areas be made worse as a result of implementing the Project; c. All feasible mitigation measures identified in the FEIS/EIR have been incorporated into subsequent actions that the City and SOCCCID commit to fully implement; d. There is no information indicating that a different Alternative should be implemented or is feasible under the MCAS Tustin Specific Plan; e. The Project does not propose substantial changes to the MCAS Tustin Specific Plan which would require major revisions to the FEIS/EIR due to new or substantially more severe significant FISH environmental effects than previously analyzed in the FEIS/EIR; f. There have been no substantial changes in circumstances under which the Project would be undertaken that would require major revisions to the FEIS/EIR due to new or substantially more severe significant environmental effects than previously analyzed in the FEIS/EIR; and g. No new information of substantial importance as described in subsection (a)(3) of Section 15164 has been revealed that would require major revisions to the FEIS/EIR or its conclusions. H. That the Planning Commission has considered the Addendum along with the FEIS/EIR, its Supplemental and Addendum, prior to making recommendation to the City Council on GPA 2013-001, SPA 2013-001, and DA 2013-002 pursuant to CEQA Guidelines section 15164, and recommend approval of the Addendum attached hereto as Exhibit 1. I. That GPA 2013-001, SPA 2013-001, and DA 2013-002 would result in the same significant and unavoidable impacts that were identified in the FEIS/EIR and these impacts are overridden for the reasons set forth in the previously adopted Findings of Fact and Statement of Overriding Considerations, attached to Resolution 00-90.

The Exchange Agreement delineates the terms and processes associated with the exchange of the ultimate ownership Of approximately 22 ao/8S Of land within the former Marine Corps Air Station (K4CAS) Tustin, on area now referred to as "Tustin Legacy." The Project also includes on amendment to the K4CAS Tustin Specific Plan to modify the permitted land uS8G and land use intensities in parts of Neighborhood A8nd to construct an extension of Bell Avenue as a Secondary Arterial; o General Plan Amendment (GPA) to add the Bell Avenue extension to the City's circulation plan and correct preexisting inconsistencies with the MCA8TuStin Specific Plan; U Development Agreement and Amended Conveyance Agreement between SOCCCD and the City (DA) and associated implementation documents; and en agreement for the funding and construction of Bell Avenue. The objectives of the Project are to rationalize property boundaries to create larger, contiguous land areas for the City and SOCCCD, provide for n broader n3n8o Of land uses in support of the objectives of the K4CAS Tustin Specific Plan, and enhance circulation in the Project area by improving east-west connectivity between the existing Red Hill and Armstrong Avenues. The Project will be approved, carried out and implemented by the City and SOCCCD. The City and SOCCCD will be taking an n8UO0 (i.8., approval) on the Project; therefore, pursuant to CEQA California Code nf Regulations, Title 14. Chapter 3, known @Sthe CEQA Guidelines, Section 15O51(C), both the City and SOCCCID are considered the Lead Agencies. The City and SOCCCD have agreed that since the City will consider the project before SOCCCD, the City will be the Lead Agency pursuant to CEQA Guidelines Section 15051(d)' and SOCCCD will be the responsible agency. The City and SOCCCD have agreed t0 jointly conduct the CEQAanalysis. 1.2 Organization of Addendum The organization of this CEQA document is according to the following sections: Section 1: Introduction Section 2: Project Description Section 3: Environmental Evaluation Section 4: Summary Vf Mitigation Measures Section 5:Sources/Acronyms Section 6: Report Preparers Appendix This Addendum inn0/0O/8teS the Environmental Checklist Form from Appendix G Of the State CEQA Guidelines as the Initial Study. The environmental issue impact questions contained in Section 3 of this document also conform to the required contents of this Environmental Checklist Form. 1.3 Previous Environmental Documentation A Final Joint Program Environmental Impact Statement/Environmental Impact Report (FEIS/BR) for the Disposal and Reuse of Marine Corps Air Station (MCAS) Tustin was prepared by the City of Tustin and the Department of the Navy (Navy) in accordance with the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA) dated October 1980. as amended by the Errata dated 1 April 2013 Agreement for Exchange of Real Property GPA 2013 -001, SPA 2013 -001, DA 2013 -002 Addendum /Environmental Checklist Introduction September 1998. The Mitigation Monitoring and Reporting Program (MMRP) for the FEIS /EIR was adopted by the City on January 16, 2001 (Resolution 00 -90). On March 3, 2001, a Record of Decision (ROD) was issued by the Navy approving the FEIS /EIR and the Specific Plan. There have been one supplement and four addenda to the FEIS /EIR. The City of Tustin certified a supplement to the FEIS /EIR on December 4, 2004 and an addendum on April 3, 2006. The District certified an addendum on November 12, 2008 ( SOCCCD Resolution 08 -35) related to the approval of a Long Range Academic & Facilities Plan and a Long Range Academic Plan for the Advanced Technology & Education Park (ATEP) campus; an addendum on March 24, 2009 ( SOCCCD Resolution 09 -05) related to a Concept Plan for Phase 3A of the ATEP campus; and an addendum on December 5, 2011 ( SOCCCD Resolution 11 -38) related to an exchange of land between the District and the County of Orange. The original FEIS /EIR document, the supplement, and the City's and District's addenda are collectively referred to herein as the "FEIS /EIR." In addition, the City has certified multiple CEQA documents associated with prior amendments to the MCAS Tustin Specific Plan and development projects within Tustin Legacy. Section 1.5.2 of the FEIS /EIR states that the FEIS /EIR is a Program EIR and it is intended to be used as the CEQA compliance document for all public and private actions made in furtherance of, the Specific Plan. The FEIS /EIR analyzed the environmental consequences of the Navy disposal and local community reuse of the MCAS Tustin 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, including but not limited to the adoption by the City of Tustin of the MCAS Tustin Specific Plan and adoption of the MCAS Tustin Redevelopment Plan, The MCAS Tustin Specific Plan proposed and the FEIS /EIR analyzed a multi -year development period for the planned urban reuse project (Tustin Legacy). When individual 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 FEIS /EIR. The agency can approve the activities as being within the scope of the project covered by the FEIS /EIR. 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.' • • • i • • ' • PF Us Pursuant to Sections 15051 and 15367 of the State CEQA Guidelines, the City is the Lead Agency for the CEQA compliance associated with the Project because it will approve, carry out, and implement the Project and will be the first agency to approve the Project. SOCCCD will be a responsible agency. Based on the analysis in this Initial Study and Addendum, the City and SOCCCD determined that the potential impacts of the Project were previously analyzed in or are substantially similar to the impacts analyzed in the FEIS /EIR and that none of the conditions identified in Public Resources Code Section 21166 or Section 15162 of the CEQA Guideless applies. The City and SOCCCD determined that they would prepare this Addendum to: (1) evaluate whether the Project's environmental impacts were already analyzed in the FEIS /EIR; (2) document the District's and City's findings with respect to the Project and its environmental determinations; and, (3) evaluate and document that a new, supplemental or subsequent EIR, Negative Declaration (ND), or Mitigated Negative Declaration (MND) or other CEQA document was not wa rra nted. This Addendum is the appropriate CEQA documentation for the project because: 1 MCAS Tustin Zone Change (Specific Plan Amendment) 05 -002, DDA and Development Plan Addendum, p. 1 -1. April 2013 Agreement for Exchange ofReal Property GPA2O13-002, SPA 2O13-001.DA2O13-0X)2 Introduction • the Project does not change the land uses that are currently permitted within the IVICAS Tustin rgl Specific Plan, the impacts of which have been previously analyzed in the FEIS/EIR; • the Project would not permit an intensification of permitted uses that would |nod to increased environmental impacts beyond those that are already identified in the FE|S/E|R; • the Project does not modify previously-analyzed projects in any substantive way; • no new mitigation measures are required; • none of the conditions identified in Public RoS0u/naS Code Section 21186 or Section 15102 of the CEQAGuide|eso applies; and, • no new significant adverse project-specific or cumulative impacts in any environmental areas were identifi8U, nor would any project-specific orcumulative impacts in any environmental areas ba made worse 8S8 result of implementing the Project. An agency may prepare en addendum to8 prior BRpursuant toCEQA Guidelines Section 15164 that Statea, in pertinent part, that: ~The kmU agency [.] sk8U prepare an addendum t0 a previously certified BR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for the preparation of a subsequent EIR have occurred." An agency may prepare an addendum to document its decision that a subsequent BR is not required. (CEQA Guidelines Section 15104, subdivisions (8)and (e) and Section 15162, subdivision (e)) The Project is consistent with and 8k]s in the implementation Of the MCAS Tustin S0eoh5n Plan. Specifically, the Project would not change the overall intent Of the Education Village (PA-1)' which is described as a "specialized educational environment with an array of public-serving uses" (K8CAS Tustin Specific Plan, pg. 2'10). The uses permitted by the DA further SOCCCD'S educational mission as discussed in SOCCCD's Long-Range Academic and Facilities Plan, dated October 2008 and which was the K. subject of8n addendum certified On November 12.2O0O(S0CCCD Resolution 0E-35). Further, relative to the UvC/8|| Tustin Legacy development, the Project would not significantly change the intensity or scale Of development approved in the Specific Plan, District's Conveyance Agreement, Long-Range Academic and Facilities Plan (LRP), and Concept Plan or analyzed in the previously certified FE|8/E|R. The Project rationalizes parcel configuration to allow for O more efficient use Of property by creating contiguous, compact, and conventionally-shaped 08rC8|S for future development pursuant to the approved land ua8S that includes complimentary commercial, offices uses and light industrial uses, joint uses, and other collaborative arrangements t0 further SOCCCD'S education objectives. As such, there are no new significant impacts resulting from the Project, nor is there any substantial increase in the severity of any previously identified environmental impacts. In addition, the circumstances under which the Project would bo implemented would not result in new nr more severe significant environmental impacts. None 0f the conditions described in Section 15162of the CEQA Guidelines have occurred. Specifically, there have not been: (1) changes to the Project that require major revisions to the previously certified FE|S/BR 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 tothe circumstances under which the Project is undertaken that require major revisions to the previous FE|S/E|R due t0 the involvement Uf new significant environmental effects or substantial increase in the severity Of previously identified effects; 0r(3) the availability ufnew information of substantial importance relating to significant effect ormitigation 0eGSu/eS or alternatives that was not known and could not have been hnOvvn when the FE|S/E|R was certified as complete. The City and S0SCCD will continue to comply with the adopted applicable IVIIVIRPS. 3 April 2013 Agreement for Exchange nf Real Property GPA2013+JO1_ SPA 2O13-001.DA2013-0]2 AUdondum/Environmenta|Cheok|iat Introduction 1.6 Evaluation mfAlternatives CEQA requires a comparative evaluation Of 8 Project and alternatives to the Project, including the "No Project" alternative. This Addendum relies on the FEIS/EIR for the evaluation of alternatives. The FEIS/EIR addressed 8 nausVn@b|8 range Of alternatives for the project. The City of Tustin is implementing Alternative 1 of the FE|S/E|R' and there is no information indicating that the City should implement different alternative Q/ that G different alternative isfeasible, Consistent with Section 15183 Of the State CEQA Guidelines that identifies which environmental evaluation is required for projects that are consistent with a community plan or zoning, there is no need to address new alternatives in this Addendum. Additionally, there are nO circumstances cited in Section 15182 of the State CEQA GuiUe|in*s, which require preparation of O subsequent E|R relative to alternatives. 1.7 Summary of Findings 8dSeU on the initial study analysis and environmental checklist prepared for the Project and pursuant to Section 15162' 15163' 15184, and 15183 of the CEQA Guidelines, the City and SOCCOD have determined, on the basis of substantial evidence in the light of the whole record, that: • The Project was examined in light 0fthe FEIS/BR and has been adequately analyzed in the FBS/BR because the Project dQCS not substantively modify the previously-analyzed proposal included in the K4C/VS Tustin Specific Plan; • The Project would not have any effects that were not already examined in the FE|8/E|H, no new mitigation measures are required, and there are no new significant adverse project-specific or cumulative impacts in any environmental an38S that were identifieU, nor vvou|0 any project- specific or Cunnu|eUve impacts in any environmental areas be rnodo wOvSR as O result of implementing the Project; • All feasible mitigation measures identified in the FBS/E|R have been incorporated into subsequent actions that the City and S0CCCD commit to fully implement; • There is no information indicating that 8 different Alternative should be implemented or is feasible under the K8CAS Tustin Specific Plan; • The Project does not propose substantial changes to the MCAS Tustin Specific Plan which would require major revisions to the FE|S/E|R due to new or substantially more severe significant environmental effects than previously analyzed in the FE}S/E|R; • There have been no substantial changes in circumstances under which the Project would he undertaken that would require major revisions to the FE|S/E|R due to new or substantially more severe significant environmental effects than previously analyzed in the FE|S/E|R; and • No new information of substantial importance as described in subsection (a)(3) of Section 15104 has been revealed that would require major revisions to the FEIS/EIR or its conclusions. 18 Intended Use mfthis Addendum This Addendum, which includes the Environmental Checklist/Initial Study for the Project, will serve as the appropriate CEQA documentation for all applicable public agency decision-makers and the public regarding the objectives and components of the Project.

Therefore, the checklist and analysis evaluate whether the environmental effects of the Project were covered in the FE|S/E|R pursuant t0 Section 151O2 and 15188of the CEOAGuidelines. The FE|8/BR on8|yznU 8 multi-year development period for the Tustin Legacy planned urban reuse project. When individual development activities within the W1CAS Tustin Specific Plan are proposed, the lead agency is required to examine individual activities to determine if their effects were fully analyzed in the FEIS/EIR. The lead agency can approve the activities as being within the scope of the project covered MEN- by the FE|S/E|R if the agency finds that pursuant to Sections 15162, 15163' 15164, and 15183 of the IN CEQA8uidC|ineS that no new effects would OSCur, nor would a substantial increase in the severity of MI�| previously identified significant effects occur. Then the lead agency can determine that nosupplemental or subsequent environmental document iSrequired. The Project will be approved, carried Out, and implemented by the City and S0CCCD. As U8SCri0eU in Section 1.1, the City is the lead agency. The City and SUCCCD have agreed to jointly prepare this comprehensive Environmental Checklist to determine if the Project is within the aCOp8 of the FE|S/E|R and if new effects would occur as a result of the Project and to document their findings in this Addendum. 1-9.1 Project Title Agreement for Exchange of R9G| Property between City of Tustin and South Orange County Community College District 1'9.2 Lead Agency Name, Address and Contact Person City OfTustin 300 Centennial Way Tustin, California 92780 Attention: Elizabeth Bin5aok' Community Development Director (714)573'3140 ' California CoU8UfRegu|8tiOnS'TWe14,DivisiOn8`Cha0t8r3(Stet8CEQAGuNe|inaS.SeCtionS15385 and 15367.

Although K4CASTuStn's boundary covered an area within the cities of Irvine and Tustin, Tustin Legacy encompasses only the area within the City of Tustin. Tustin Legacy is a 1'511'88re mixed-use project, which will ultimately include houSing, various commercial businesses, a various light industrial uses, schools, and community and regional parks. Portions Of Tustin Legacy are dev8|OpeU, including an approximately one-million-square-foot uutU0O/ shopping mall Oa||oU "The District," single-and multi-family home oommunitieS, an elementary sohUO|' o h8mC|eGE/tnanSiUOn@| shelter, an abused and neglected children foci|ity, a sheriff academy facility, Phase | of the ATEPCampus and focal parks. The city of Santa Ana borders Tustin Legacy k>the south and southwest. Tustin Legacy isinclose proximity to five freeways: the Costa Mesa (SR-55). Santa Ana (1-5)' Laguna (SR- 133). Garden Grove (SR'22).and Gen Diego (1-405) freeways (See Figure 1). Major roadways bordering Tustin Legacy include Rod Hill Avenue On the west, E0ingorAxenuo/|rvino Center Drive on the north, Jamboree Road on the east, and Bo/nanCa Parkway on the south. ]8mUO/ee Road provides access tOthe Eastern Transportation Corridor (SR'281to|| road). John VV8yn8 Airport is located approximately 3.5 miles to the south, and the Tustin Metn}|inkC0mmuter Rail Station is located approximately 11/2 miles tothe northeast of the Project site. The Project site is located near the northwestern corner of Tustin Legacy. The Project site consists of8Bacres located within PA1,which isG12�3-acre portion of Neighborhood A (Figure 2). To the west of the Project site is Red Hill Avanu8, north is a vacant Site that is planned for public community park, east is Armstrong Avenue, and south is a future extension of Warner Avenue and WMEM Rancho Santiago Community College District (RSCCD)Shoriff's Training Academy (Figure 3). �� Owners of the 80 acres include the City, SOCCCD. and the Navy. The SOCCCD'o parcel will ultimately be built out as the Advanced Technology & Education Park (AJEP). Navy land ownership in the project area will decrease over time in favor of the other landowners and the County of Orange, as hazardous materials are removed and lands heC0nne available for development. During the clean-up 0n]Coss' Navy lands are CUntn}||ed by the other three local Ovvn8nS under Lease in Furtherance of Conveyance (L|FOC) agreements, Table 3 provides a breakdown of land ownership in the project area.

Each of these components are described in more detail below. 2.2.1 Exchange Agreement between City and S8CC[D An Exchange Agreement between the City and SOCCCD is proposed to delineate the terms and p/OOeSSeu associated with the exchange of the ultimate ownership of land currently within the reSV8obvC parties' ownership in fee or in the form of a lease or sublease. The Exchange Agreement provides for an exchange Of8 sites covering 22 acres within Neighborhood A, as shown in Figure 5. Table 5 details the ownership interests and to which party each area is transferred. In addition to rationalizing property boundaries for both the City and SOCCCD. the |onU exchange will allow for creation of new public (City-owned) right-of- way for the extension of Bell Avenue from Red Hill Avenue to Armstrong Avenue. Two parcels included in the Exchange Agreement are currently owned by the N@vy. Such lands are expected to be transferred to the City and SOCCCO once 8 Finding Of Suitability to Transfer (FOST) is issued by the Navy for the }@nUS. Once issued, the FDST will document that the Navy has determined the 0anCe|S environmentally suitable for transfer and that either OU remedi8tiOn necessary to protect human health and the environment has been completed or is in place and operating properly and successfully such that development can safely occur on the site.

The Project Traffic Study (Appendix A) determined that with the extension of Bell Avenue, increased roadway capacity is available in the circulation system. The Bell Avenue extension would reduce traffic congestion at the Red Hill AxenuD/VV8/ner/venu8 intersection and the Red Hill Avenue/Valencia Avenue intersection, and provides an alternative route for motorists accessing Tustin Legacy. These factors permit the inCn38S8 of the current vehicle trip cap for the WCAS Tustin Specific Plan. The trip Cap for Neighborhood A is the maximum number Oftrips that new development can C/e8t9 without requiring additional environmental review for traffic. The current trip cap was evaluated in the FE|S/E|R. The prior trip C@0 for the ATEP Site Agreement for Exchange of Real Property GP42013-002, SPA 2O13-0XJ1.DA2O13-002 Addendum/Environmental Checklist Environmental Evaluation was 5/47OADT and for the City parcels 1,072ADT As detailed in section 3.1O,with the construction of Bell Avenue. levels Of peak-hour traffic congestion would decrease at several locations despite the increased development square footage included in the Project, The Traffic Study determined that, based on the Size and configuration of the Bell Avenue CxtGnSkm, average daily trip (AJ}T) volumes (the measure used in establishing the MCASTu5tin 5pocdiC Plan trip cap) may be increased by 10,000 ADT without triggering significant adverse effects on the roadway system. This additional roadway capacity is proposed t0 be split evenly between properties owned by the City and SOCCCD (that is, each entity would Ue permitted 8n additional 5.000ADT). The City anticipates that only about 25 percent of its O||0Ootion of 5,000 AOT (up to 1.250 ADT) would be used within Neighborhood A; the remaining trips (3'750 ADT) vvOu|U be made available for additional development in other areas of Tustin Legacy. The full amount of these trips will not be needed because the City recently amended the K4OAS Specific Plan to include government office uses in Neighborhood AtO accommodate an expected relocation of the Army Reserve operations from the southern boundary of Tustin Legacy. A total of 1.250 ADT is sufficient for the Army Reserve operations. The specific location of where the balance of these trips will UO assigned has not been determined and the City will determine at that time whether subsequent CEQA and traffic analysis may be needed when the trips are allocated to 8 specific location within Tustin Legacy. The proposed inCna8Se in trips is negligible compared to the overall WAS Tustin Specific Plan planned trip count 8f210,44OADT. The City and SUCCCDare entering into 8n agreement for the funding and construction 0f Bell Avenue to ensure the roadway is timely constructed. Further, there are two other sources Uf trips that are assigned to Neighborhood A, but are not allocated to a specific parcel: (1) 6,220 trips associated with the "Tustin Facility" and (2) 2,083 trips related t0 commercial uses in Planning Area 1, The FE|S/E|R analyzed impacts assuming these 8,903 trips will he assigned to Neighborhood A parcels. However, with this project, the City has determined it is unlikely that these 8,903 unallocated trips will be assigned L0 parcels in Neighborhood A. The 5.000 b'i0S being assigned to SOCCCD's parcel are /CSo than the ~�~ combined number of 8,903 unallocated trips, and therefore, as is demonstrated in the traffic impact analysis, the impacts are not expected to exceed that amount previously analyzed. The City will determine whether subsequent OEQAend traffic analysis will be needed when these 8,803 trips are assigned to o parcel. Until the City makes this determination, it is speculative to and not reasonable tO assume the trips will Ua assigned tn parcels in Neighborhood A. 2.2.3.3 Amended List of Allowed Land Uses in Neip-fhborhood A Referencing the pn)poSoU planning areas shown in Figure 0` pennU±8d t]nU uses would be amended on PA 1-B, 1-E. 1'H, |'K, and I-L to explicitly include various types of complimentary commercial, OffiCC and light industrial uses, joint uooS. and other collaborative arrangements to furtherSOCCCD'S education objectives. The Conveyance Agreement, Long Range Academic and Facilities Plan, and ATEP Phase 3A Concept Plan all identify and permit various Office and COmmenoiO| uses, including (as a partial list): office and retail service uses; office facilities used for basic and applied research, testing, and consulting; and industrial/commercial business incubators Supporting educational programs. The proposed changes to the list of allowed uses would remove ambiguity related to commercial and light industrial uS8S on the ATEP site. Such uses *0u|U be permitted in these planning areas only if the Exchange Agreement is executed. Additionally, such uses would be permitted in RA 1-B, but only in the event an exchange of h5nU occurs between the City and SOCCCD and if an agreement is reached between the County and S0CCCD for County's future ownership 0fPA1,|.

Uses in Land Use Category 1 consist of uses that are education-oriented, including all facilities normally found 0ncollege campuses, such a5 classrooms; labs; administration facilities; student support; cafeteria and food S9m|CeS; bookstore; photocopy services; dormitory and student housing; workforce center; ma i nten ance/secu rity/sto rage facilities and structures: security and guard houses, gates and other security facilities and structures; student health services; other uses which include facilities for traditional and non-traditional advanced education (extension and/or 8UvonoeU degree opportunities), adult Cdunation. continuing education' vocational, job and educational training, and other education and training. The educational activities in buildings categorized as Land Use Category 1 may be undertaken by public, non-profit Or for-profit educational institutions; pmvk18U. however, that a Substantial portion Of the educational activities in Land Use Category 1 Building Area will be conducted by public or non-profit educational institutions.

Uses in Land Use Category 2 consist of non-educational, income producing uses, including private sector uses, provided that such uses UO not adversely impact the trip cap under the K4CAS Tustin Specific Plan or other environmental impact category thresholds in the CEQA Documentation, or require a Specific Plan Amendment or further environmental documentation. Up to 100 percent Ofthe Building Area on the SOCCCD Property may be dedicated to Land Use Category 1 uses. At build-out, at least 51 percent of the building area on the SOCCCD property must be devoted to Land Use Category 1 Uses. The building area will not exceed that permitted pursuant to allocation of ADT's to the SOCCCD property. AS SpeodiC development proposals are considered for the Project site, ADT OG|Cu|aUOnS will be required, using the trip generation rates previously identified in the FBS/E|R, to show that the trip cap is not exceeded. VVhi|8 a specific development pn}pOSa| is not in8|uU8U in this analysis, two preliminary calculations have been 0nn0uoCd t0 provide examples of typical development amounts that o0u|U result from development in two scenarios, described below and summarized in Table 7. 21 April 2013 Agreement for Exchange of Real Property CPA2O13{}01, SPA 2013-001,DA2O13-0X)2 Addendum/Environmental Checklist Environmental Evaluation The first scenario assumes the ATEP site v0ukj be developed with approximately 51 percent academic uses (Land Use Category 1) and 49 percent general office uses (Land Use Category 2). Using the FEIS/EIR trip generation rates, 8 total of 1,087,970 square feet ofdevelopment (including 554'870 square feet of academic space and 533.100 square feet of Office 8p8C8) would be permitted on the ATEP nmmVuS. This is an inona8S8 in U*ve|U0nnent capacity of 194,119 square feet from the 893.851 square feet previously permitted 0n the ATEP site.

This would extend Bell Avenue from its current terminus at Red Hill Avenue to a new intersection at Armstrong Avenue. The extension would be a Secondary Arterial -level roadway with a 92 -foot right -of -way, four travel lanes, a painted median allowing left turns, Class 11 bicycle lanes, and sidewalks. A signalized intersection may be located approximately at the midpoint along the roadway extension, depending on the future development configuration on either side of Bell Avenue. Construction of Bell Avenue is occur in 2017 would take approximately six to eight months. 3.

Therefore, the Project and its implementation are consistent with and previously analyzed in the FE|S/E|R and no new mitigation measures are required in relation to impacts to air quality. Although the Project analyzed in this Addendum would not independently create significant air quality impacts, the broader project on the KXC/VSTuStin She was found in the FEIS/E|R to result in significant unavoidable air quality impacts. Consistent with these findings, development on the Project site could also result in significant unavoidable long-term and cumulative air quality impacts because it is part of the "project" analyzed in the FBS/BR for which this finding was made. Mitigation measures included in the FE|S/BR will be implemented as 800nJphOte by the City and S0CCCD. The City and 5OCCCD will implement Mitigation Measures AQ-1through AQ-3. The implementation Of Mitigation K8oeSu/8AQ-4 is the responsibility of the City and/or the City of Irvine, and is not within the responsibility of the SOCCCD. Based on the foregoing, none of the conditions identified in CEQAGuiU8Unes Section 15182 exist that would trigger the need to prepare a subsequent or supplemental EIR or other environmental document to evaluate Project impacts or mitigation measures with regard to air quality. Specifically, there have not been: (1) changes to the Project that require major revisions of the previous FE|S/E|R due to the involvement of new significant environmental effects Ora 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 FE|S/E|R due t0 the involvement of new significant environmental effects Or O substantial in0/e8SC 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 FE|S/E|R was certified as complete. Specific air quality mitigation measures have been adopted by the Tustin City Council in certifying the FBS/BR for both operational and construction -related activities for development GtTustin Legacy. The mitigation measures for air quality impacts that are applicable to the Project during the future implementation stages (i.e., construction) include Mitigation Measures AQ'1and AQ'2. The City and GOCCCD would implement Mitigation Measure 4Q'1 by complying with South Coast Air Quality Management District Rules to reduce short-term air pollutant emissions. Mitigation Measure AQ'2 would beimplemented by requiring the use of low volatile organic compound (VOC) architectural coatings for all interior and exterior painting operations. Mitigation K18@gur8 A]'3 which relates to Transportation Demand Management Plan (TDK8)will be implemented for new non-residential projects with 1O0Urmore employees and expanded projects where additional square footage would result in8total 0f1DOormore employees. As stated above, the FEkS/BR also concludes that Specific Plan-related operational air quality impacts are significant and cannot be fully mitigated. A Statement of Overriding Considerations for the FBS/E|R was adopted by the Tustin City Council on January 16, 2001 to address significant unavoidable short- term, long-term, and cumulative air quality impacts associated with all development of the Specific Plan. No new mitigation measures are required.

Responses to a-f: No Impact Due to No Substantial Change from Previous Analysis. The Project would not cause impacts to biological resources that were not previously analyzed in the FBS/E|R. The FBS/E|R analyzed the future development of the whole of Neighborhood A and the associated biological impacts. No new areas will be developed under the Project. There are no new Or increased significant adverse project-specific Or cumulative impacts with regard to bi0|0Qioa| resources that would Oo0u/ as O result of the adoption and implementation of the Project. In 2010, the U.S. Army Corps of Engineers (AC0E), Regional Water Quality Control Board (RVVQCB), and California Department of Fish and Game (CDFG) determined that the AJEP Site does not contain land that is subject to their jurisdiction or that warrants their oversight. There is no other new information relative to Ui0|OgiCe| resources that was not in existence at the time the FE|S/E|R was prepared. Therefore, the Project and its implementation are consistent with the FEIS/EIR and no new mitigation meoSunao are required in relation to impacts on biological resources. Based on current delineations of wetlands and jurisdictional waters, the Project will not affect wetlands or jurisdictional waters. The impacts resulting from the implementation of the PnojeCt, if any, vv0u(d be those identified in the FE|S/E|R. Based On the foregoing, none of the conditions identified in CEOA Guidelines Section 15102 exist that would triggerthe need to prepare a subsequent or supplemental EIR or other environmental clocumentto evaluate Project impacts or mitigation measures with regard t0 biological nogOuroeS.

Therefore, the Project and its implementation are consistent with the FE|S/E|R and no new mitigation measures are required in relation to impacts tO geology and soils. The FEIS/EIR found that impacts to soils and geology resulting from implementation of the Specific Plan would include non-seismic hazards (such BS |oo8| settlement, regional subsidence, expansive soils, slope in8t8Ui|hy, erosion, and mudf|0wS) and seismic hazards (such as surface fault displacement, high- intensity ground shaking, ground failure and lurching, seismically-induced settlement, and flooding associated with dam failure).

Implementation Vf the Project would not result in any substantial inCna8s8 in GHG emissions COmp8n9d to the Specific Plan analyzed in the FE|S/E|R. The Project modifies the project analyzed in the FE|S/E|R by including on extension to BH|| Avenue, construction of academic and office space beyond the previously-analyzed amountS, and an increase in the trip cap. These modifications to the MCAS Tustin Specific Plan as amended project are assessed in the AQ|A (Appendix B). In O/de/tU GSSeSS the GHG emissions impacts, the AQ|A report assumed the construction of an additional 816,929 square feet of academic space beyond that currently permitted. The report also analyzed the impacts 8SS0oiGted with 1Q4,1OG square feet Vf academic and office space; however, because the larger amount Of square feet would result in greater emissions, the following only references the emissions @SaoCi8teU with the greater square footage number. Emissions associated with the lower square footage number can Uo found in Appendix B. Table 10 shows calculated GHG emissions resulting from Project implementation. The table includes operational emissions as well as construction emissions amortized over 30 years, as required by SCAQK4D. On December 5,2O08 the SCAQK4D Governing Board adopted an interim quantitative GHG Significance Threshold for industrial projects where the SCAQMD is the |o8d agency (9.g.. stationary source permit projects, ru|os, plans, etc.) Of 10.000 metric tons (MT) of COu equivalent per year. The threshold applies primarily to industrial facilities. No threshold for residential or commercial development has been promulgated. In the absence of any adopted thresholds for roadway and oOmm8/Cio| facilities projects, the AQIA uses the 10,000 MT/year recommendation as a guideline for this impact analysis. 41 April 2013 Agreement for Exchange of Real Property QPA2013'0O2` SPA 2O13-0}2,DA2O13-002 Addendum/Environmental Checklist Table 10.

Federal regulations require the Navy to COm0|ote namedietion of hazardous materials prior to conveyance of VnD0ert|eS to other landowners. Portions Of the Project site are presently undergoing /em8diet|On, and therefore remain under Navy ownership. These areas are available for limited used by the future owners (the City and SOCCCD) under L|FOCagrC8ment. They will not be conveyed to the future owners until the Navy determines that its remediation of hazards and hazardous materials in these areas have sufficiently progressed to the point that the property can safely be developed. Asbestos-containing materials (ACMS) and lead-based paint (LBP) were identified in previous surveys within the Project site, There are well-established existing |ewS and procedures for rem8UiaUngthege two conditions. RomediatiVn of these Conditions have been addressed as part of a building demolition program on SOCCCD properties, and will also be implemented by the City as demolition proceeds on their properties.

The Navy is responsible for planning and executing environmental restoration programs in response to releases of hazardous substances for MCAS Tustin. The FEIS /EIR concluded that the implementation of the Specific Plan would not have a significant environmental impact from the hazardous wastes, substances, and materials on the property during construction or operation since the Navy would implement various remedial actions pursuant to the Compliance Programs that would remove, manage, or isolate potentially hazardous substances in soils and groundwater. As identified in the FEIS /EIR, the Project site is within the boundaries of the Airport Environs Land Use Plan (AELUP) and is subject to height restrictions. The Project does not propose changes to the 100 -foot height limitation included in the Specific Plan, The Project site is not located in a wildland fire hazard area. Based on the foregoing, none of the conditions identified in CEQA Guidelines Section 15162 exist that would trigger the need to prepare a subsequent or supplemental EIR or other environmental document to evaluate Project impacts or mitigation measures with regard to hazards and hazardous materials. 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 FEIS /EIR 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 FEIS /EIR was certified as complete. �w Mitigation /Monitoring Required: No new impacts or substantially more severe impacts will result from implementation of the Project; therefore, no new or revised mitigation measures are required with regard to hazards and hazardous materials.

The Project will not cause direct impact to hydrology and water quality. While the project would permit an increased development square footage, all such development would be required to comply withtheD'ourrRnt Water Quality Management Plan 49 Apri 12013 Agreement for Exchange of Real Property GPA2O13-002, SPA 2O13-0N2,DA2O13-0N2 Addandum/Environmenta|Cheok|iat Environmental Evaluation (VV0K8P) requirements imposed by the Santa Ana Regional Water Quality Control 8oen1. Additionally, the Project does not include any change to setbacks or other development standards that impact drainage. Any changes in drainage resulting from construction of 8*|| Avenue will be compliant with the master drainage plan in place for K4CAS Tustin, as analyzed in the FE|S/E|R. Construction of the roadway will also require preparation 0f8 VVQK4P. There are no new Urincreased significant adverse pnojeCt'S0oCifiO0r cumulative impacts with regard to hydrology/water quality that are identified as a result of the adoption and implementation of the Project. There is no new information relative to hydrology/water quality that was not in existence at the time the FE|S/E|R was prepared. Therefore, the Project and its implementation are consistent with the FEIS/EIR and no new mitigation measures are required in relation t0 impacts to hydnJ|O§y/vvaterquo|ity. As concluded in the BIS/E|R,preparation ofaVQMP for future development projects On the Project sites in compliance with all applicable regulatory standards would vudu0a water quality impacts from development activities to G level of insignificance. The Project would not result in new or substantially more SevCn} impacts t0 water quality than what was previously identified in the FE|S/E|R. The Specific Plan considered the development of education-oriented and public services land uses on the Project site. Futuna development would require preparation of a VVOMP that limits Off-Site st0rmwote, f|0vS. The Project would not naSu|t in an increase of impervious surface area from the amount that was previously analyzed in the Specific Plan. The Project proposes no Change t0 the drainage pattern and water management systems previously analyzed in the FE|S/E/R. The drainage pattern and water management systems in the Project site vicinity would remain consistent with the Tustin Legacy Master Drainage Plan. Therefore, the analysis and conclusions in the FEIS/EIR relative to impacts related to groundwater supply, groundwater levels, or |nOa| recharge have not Changed substantially. In addition, no change to the backbone drainage system is proposed. Therefore, no new or more severe impacts related t0drainage patterns, drainage facilities, and potential flooding would result from the Project. Based on the foregoing, none of the conditions identified in CE0A Guidelines Section 15102 exist that would trigger the need toprepare a subsequent Or supplemental E|Ror other environmental document tn evaluate Project impacts or mitigation me8SunaS with regard to hydrology and water quality, Specifically, there have not been: (1) changes to the Project that require major revisions of the previous FE|S/E|Rdue to the involvement Of new significant environmental effects Or a substantial increase in the severity Of previously identified effects; (2) substantial ChenQnS with respect to the circumstances under which the Project is undertaken that require major revisions of the previous FE|S/E|R to the involvement of new significant environmental effects or 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 FE|S/E|R was certified 85complete. : Compliance with existing rules and regulations would reduce any potential impacts re|8h8U t0 water quality and groundwater to 8 level of insignificance and no new mitigation is required. The mitigation measures applicable during implementation (i.e.. construction) of the Project have been identified in the City's adopted MK4RP. K8iUg8UOn Measures VVQ'1,VVQ'2. and VVQ'4 establish requirements related t0 preparation of St0rmw8ter Pollution Prevention Plan, compliance with VVOSte Discharge Requirements, and preparation of Water Quality Management Plan, respectively. No refinements are necessary tOthe FE|8/E|R mitigation measures and no new mitigation measures are required for implementation of the Project. The Project will implement the relevant mitigation measures of the adopted MMRP and aS stated in the FE|S/E|R and 2O12MK4RP. MitioationlMonitorino Not Beino Implemented: Mitigation MeOSu/8VVO-3 requires others to participate in the RVV0CB's Nitrogen and Selenium Management Program (NSK4P)VVOrking Group and contribute to funding and implementing the Working Plan. Because this mitigation measure is the responsibility of others to implement, it does not fall within the responsibility of the Project to implement. 50 April 2013 Agreement for Exchange of Real Property GPA 2013 -001, SPA 2013 -001, DA 2013 -002 Addendum /Environmental Checklist Environmental Evaluation RE E r Sources: Field Observations Consultation with Psomas Engineering `t Existing Water Quality Management Plan (WQMP) ATEP Phase 3A Concept Plan Addendum /initial Study ATEP LRP Addendum /initial Study as amended by November 2008 Errata ATEP LRP, as amended by the October and November 2008 Erratas ATEP LRAP as amended by the October 2008 Errata FEIS /EIR for Disposal and Reuse of MCAS Tustin (pp. 3 -98 through 3 -105, pp. 4 -124 through 4 -129, pp. 7 -29 through 7 -30, and Addendum (pp. 5 -56 through 5 -92) and Final Supplement #1 MCAS Tustin Specific Plan /Reuse Plan (pp. 3 -35 through 3 -62, pp. 3 -70 through 3 -81, pp. 3 -82 through 3 -88, and pp. 3 -104 through 3 -137) Tustin General Plan 2012 City of Tustin Annual Mitigation Monitoring Reports City of Tustin Resolution Nos. 00 -90, 04 -77, and 06 -43 .4 51 April 2013 Agreement for Exchange of Real Property GPA2O13'002, SPA 2013-0N1.DA2O13-0x]2 Addendum/Environmental Checklist 3.10.1 Existing Conditions Environmental Evaluation The SOCCCD approved the Long Range Academic and Facilities Plan, which pertains to thCATEP portion of the project area, in November 2008. Phase 1, the existing On9'8ure ATEP campus, is currently offering educational programs. The Phase 3A Concept Plan, a 28-acre expansion of the AJEP OGm0uS, was approved and CEQA review (in the form of an Addendum to the FEIS/EIR) was completed by the District in March 2009. The former military buildings on the SOCCCD parcels have been demolished. No specific development for the County Parcel has been proposed, The County parcel is still under the control of the Navy, and will remain So until the FOST is issued.

Mitigation Incorporation Responses tVa-c: No Impact Due b0 NV Substantial Change from Previous Analysis: Implementation of the Project will not CBuS8 any direct impacts to land use and planning. There would be no change to building height restrictions, setbacks, Signoge. and other development standards. Development intensity (the amount of total square footage and corresponding FAR) vv0u|d be permitted t0 increase, but this increase would be negligible compared to the total amount of planned development within Tustin Legacy, and would continue t0 be subject to trip caps imposed by the KiCAS Tustin Specific Plan. The Project includes an increase in the trip cap as a result of increased n)advv@y capacity provided by the Bell Avenue extension. ��� 52 April 2013 Agreement for Exchange of Real Property GPA 2013 -001, SPA 2013 -001, DA 2013 -002 Addendum /Environmental Checklist Environmental Evaluation There are no new or increased significant adverse project- specific or cumulative impacts with regard to 0- land use and planning that are identified as a result of the adoption and implementation of the Project. 1ua 0 OEM There is no new information relative to land use and planning that was not in existence at the time the FEIS /EIR was prepared. Therefore, the Project and its implementation are consistent with the FEIS /EIR and no new mitigation measures are required in relation to impacts to land use planning. The Project would not physically divide any Specific Plan land use (no community exists in the area of the Project), conflict with the Specific Plan, or conflict with any habitat conservation plan or natural community conservation plan. The project aids in the build -out of Tustin Legacy by rationalizing property ownership boundaries and improving accessibility from Red Hill Avenue. Based on the foregoing, none of the conditions identified in CEQA Guidelines Section 15162 exist that would trigger the need to prepare a subsequent or supplemental EIR or other environmental document to evaluate Project impacts or mitigation measures with regard to land use and planning. 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 FEIS /EIR 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 FEIS /EIR were certified as complete. MitiOation /Monitoring Required: The FEIS /EIR concludes that there would be no significant unavoidable land use impacts. The Project and its implementation do not result in new or increased land use impacts in comparison to those previously identified in the FEIS /EIR. The mitigation measures applicable to the Project were implemented following adoption of the MCAS Tustin Specific Plan. No refinements are necessary to the FEIS /EIR mitigation measures and no new mitigation measures are required. The District and County will implement the relevant mitigation measures of the adopted MMRP that are applicable to the Project. Mitigation Measures LU -2(m), (n), (o), (p), (q), (r), and (s) are addressed in Section 3.13. Mitigation /Monitoring Not Beim" Implemented: Mitigation Measures LU -1 and LU -2 required the Cities of Tustin and Irvine respectively to amend their General Plans and zoning ordinances for the Tustin Legacy Project, and therefore are not within the responsibility of the Project. LU -2(a) requires that infrastructure construction be properly phased by the Cities of Tustin and Irvine, and therefore is not within the responsibility of the Project. LU -2(b) is not applicable to the SOCCCD since no recording of subdivision maps is proposed as part of the Project. Per the City's adopted 2012 MMRP, the SOCCCD recorded the necessary easements for the Property and Mitigation Measure LU -2(b) has been fulfilled. Mitigation Measure LU -2(c), regarding funding construction of capital improvements, does not apply to the SOCCCD because the City exempted the SOCCCD's property from fair -share backbone infrastructure fees (per section 4.7.1.2 of the District Conveyance Agreement). The Exchange Agreement provides that the exemption applies to the currently County -owned parcel (proposed PA 1 -B) once it is transferred to the SOCCCD. Measures LU -2(g) and (i) are not applicable because the Project site is not within the 100 - year flood plain (see Federal Emergency Management Agency (FEMA) Map dated August 9, 2002), and thus these Mitigation Measures are not within the responsibility of the Project. Mitigation Measure LU- 2(h), regarding obtaining regulatory agency approvals prior to construction of regional flood control facilities, is not within the responsibility of the Project because it only applies to the Tustin Legacy developer(s). Mitigation Measure LU -2U), regarding local drainage systems, is not applicable because no subdivision maps are being recorded as part of the Project. Mitigation Measure LU -2(k), regarding the ,,s completion of drainage studies prior to grading for new development, is not applicable because the 53 Apri 12013 Agreement for Exchange of Real Property GPA 2013 -001, SPA 2013 -001, DA 2013 -002 Addendum /Environmental Checklist Environmental Evaluation Project does not include any grading or construction activities. Mitigation Measure LU -2(I), regarding an g g a reement with the Orange Count Flood Control District for fair -share contributions to flood control y facilities, is not applicable because no subdivision maps are being recorded as part of its Project and the Mitigation Measure only applies to the City of Tustin. In addition, the City exempted the SOCCCD's Property from fair -share backbone infrastructure fees per section 4.7.1.2 of the Conveyance Agreement. Mitigation Measure LU -2(t) is not applicable because no school fees are required for the Project. Mitigation Measure LU -2(u) is not applicable because the Project does not require a contribution to park facilities. Mitigation Measure LU -2(v) is not applicable to projects within the City of Tustin, and therefore is not within the Project's responsibility to implement. Measure LU -2(w), regarding the creation of a landscape maintenance district, is applicable to the Tustin Legacy developer, and therefore, is not within the Project's responsibility to implement. Finally, Mitigation Measure LU -2(x) is not applicable to the Project because no subdivision map is proposed as part of the Project, the Project is not adjacent to the Barranca Channel, and the City will provide any necessary bikeways along Red Hill Avenue.

The Project would permit an increased trip map of 10,000 ADT Noise associated with this increase in vehicular movements was assessed in the Traffic Noise Impact Analysis (NIA) prepared by Giroux & Associates in K48mh 2013 (Appendix C). Noise impacts are considered significant if they expose persons t0 levels in 8xcoSS of standards e6tGNiSh8U in |008| general plans or noise ordinances or create a substantial noise impact.

Traffic noise along Armstrong Avenue South of Valencia Ave. n0uk1 experience 8 noise increase Of +2 dB CNEL at 50 feet from the roadway centerline, but this is less than the level of human detection and less than the significance threshold. Additionally, the "with project" future traffic noise level is SdU less than 85 dB CNEL, the noise compatibility threshold adopted by the Qty of Tustin for exterior residential use. The next highest project-associated traffic noise increase is on Red Hill Avenue between Bell Avenue and Valencia Avenue. This +1.0 c1B CNEL increase is similarly less than significance thresholds and would not create dot8CtaU|R noise increase. Traffic noise associated with the addition of 10,000 trips is therefore not expected to create a significant noise impact. Short-term noise impacts were analyzed in the FEIS/EIR; implementation of the Project would be required to comply with applicable adopted mitigation measures and state and |oO@| vBQu|ahOns and stanUa/dS, along with established engineering procedures and techniques, thus avoiding significant short-term construction-related noise impacts. The Project site is not |0Oot8d within the 80 CNEL contour for airport operations.

This additional roadway capacity i8 proposed to be split evenly between properties owned by the City and SOCOCD (that is, each entity would be permitted an 8UUibOn8| 5,000 ADT). The City anticipates that only about 25 percent Of its 3||OC8UOn of 5,000 ADT (up to 1.250 ADT) vvQu|d be used within Neighborhood A; the remaining trips (3,750 ADT) vv0u|d be made available for additional development in other areas of Tustin Legacy. The full amount 0f these trips will not UH needed because the City recently amended the K4CAS8peoifiO Plan t0 include government office uses in Neighborhood A to accommodate an expected [e|0n8ti0n of the Army Reserve operations from the southern boundary of Tustin Legacy.

There is no new information relative to traffic and transportation that was not in existence at the time the FE|S/E|R was pny08nod and no new mitigation measures are required in relation to impacts t0 traffic and transportation. Based on the foregoing, none of the conditions identified In CEQA Guidelines G8O1Un 15152 exist that would trigger the need to prepare a subsequent or supplemental EIR or other environmental document to evaluate Project impacts or mitigation measures with negoK1 to recreation. Specifically, there have not been: (1) changes to the Project that require major revisions Of the previous FE|S/E|R 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 tuthe circumstances under which the Project is undertaken that require major revisions of the previous FE|S/E|R due to the involvement of now significant environmental effects or 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 FE|S/E|R was certified as complete. MiNd The mitigation measures applicable during implementation Of the Project have been identified in the City's adopted MMRP, Mitigation Measure T/C-1 requires that prior to the approval of site development permit, the City OfTustin must review and approve the pr0pnSDU traffic control and operations plans that would minimize the traffic impacts of proposed construction activity. The plans ShB|| address roadway and lane c|OSureS, truck hours and routes, and notification procedures for planned short-term or interim changes in traffic patterns. Mitigation Meaaun*ST/C'2 through T/C'9' !A,1. |A,2. and |A,5 are implemented by the City Of Tustin and/or the City Of Irvine. No refinements are necessary tUthe FE!S/E|R mitigation measures and no new mitigation measures are required for implementation (i.e., construction) of the Project. The Project will implement the relevant mitigation measures of the adopted K4MRP and as stated in the 2012 MK4RP. NO new impacts Or substantially more severe impacts will result from the District's adoption and implementation of the Project than originally considered by the previously certified FE|S/E|R. Therefore, no new or revised mitigation measures are required, Miti0ationlMonitoring Measures Not Beino Implemented: Mitigation Measure k\-3 requires that prior t0 approval of 8 development permit, the City ofTustin Sh8U review traffic information provided for the project by the project developer. The City is required to evaluate project traffic impacts utilizing the circulation system and capacity assumptions included in the FE|S/E|R. Compliance with this Mitigation Measure has been completed through the Traffic Study 0n5p8ned byStanteOand included in Appendix to this Addendum. The project would not exceed traffic capacity thresholds or require the implementation of traffic mitigation measures. With the approval of the Amended and Restated Conveyance Agreement, nD further action i8 required in compliance with Mitigation K4985un5 |A'5. For Mitigation Measures |A,0 and IA-7, the City has determined that no off-site roadway improvements are needed on the Project site.

Mitigation Incorporation Responses to a-g: ON No Impact Due to No Substantial Change from Previous Analysis: The Project would not result in any changes tOthe utilities 0k3n presented in the Specific Plan. Any demolition, removal, replacement, and connection with new underground utilities and service systems in the adjoining streets would occur as previously analyzed in the FE|5/E|R. The Project's increased size of 194.119 square feet (based on the more likely scenario of 51 percent academic space and 49 percent office space) t0 816,929 square feet (based on the less likely scenario of 100 percent academic space) would yield only a negligible impact on utilities C0m0@n3U to the full ScO0o Of the K4UAS Tustin Specific P|8n, which included u0 to 4'001 residential units and over 11.4 million square feet of commercial, institutional, and recreational buildings. The fU|| scope of this much |8/ge/ development was evaluated in the FE|S/E|R as Alternative 1; however, the K4CASTuStin Specific Plan was ultimately approved with 10.4 million square feet Ofnonresidential land uses. There is approximately 1 million square feet Of nonresidential uses that was fully analyzed in the FE|S/BR but was not incorporated into the K4CASTuSt|n Specific Plan. The Project represents fewer square feet than the excess square footage analyzed in the FE|S/E|R and therefore the Project impacts have already been assessed in the FE|S/E|R. As individual buildings are proposed on the Project site, an evaluation of utility needs will occur to ensure the appropriate connections are provided. Project facilities would oOm[dy with |Voe| and State code requirements related to water efficiency and the minimization of wastewater and solid waste generation. Impacts related to these utilities were evaluated in the FE|S/E|R, and the project would result in only negligible change in the water use and wastewater and solid vv8Ste generation. Relative to StormvvGter, the Project would be required to prepare and implement VVQW1P consistent with then-current standards. This would result in substantial On-Site water retention and infi|tr8tiOn, thereby reducing off-site drainage flows and minimizing impacts t0 the |Oo8| drainage system. All storm drains vv0u|U be designed in compliance with the Tustin Legacy Master Drainage Plan. 75 April 2013 Agreement for Exchange of Real Property QPA2O13-001.

The purpose of this report is to identify and evaluate how the proposed project differs from the original Specific Plan and any subsequent approved Specific Plan amendments in terms of traffic impacts pursuant to City-adopted California Environmental Quality Act (CEQA) thresholds of significance. The traffic study is in support of the Specific Plan Amendment and is a Supplemental to the previously approved EIR/EIS carried out for Tustin Legacy. It should be noted that the Specific Plan land uses as well as the circulation system that were assumed in previous Tustin Legacy studies outside the proposed project site as carried out for the 2010 Specific Plan Amendment are included here. 1.1 Project Description The project includes proposed changes to South Orange County Community College District's (SOCCCD) Advanced Technology and Education Park (ATEP) campus and a parcel owned by the City of Tustin. The easterly extension of Bell Avenue from its existing terminus at Red Hill Avenue to Armstrong Avenue is also part of the proposed project as the extension provides additional capacity to the surrounding circulation system allowing increases in land use intensity in the ATEP IME M campus and the city-owned parcel south of ATEP. Collectively the land use changes and extension hereinafter will be called the "proposed project." The results of the proposed project will be compared to conditions without the extension and land uses according to the Specific Plan Amendment approved in 2010. The land uses that are part of the proposed project are comprised of a 51/49 mix of learning center and office uses. The land uses in the city's parcel are assumed as community commercial and general office uses whereas previously a special generator was identified for the parcel. Direct project access is provided by Valencia Avenue, Warner Avenue, Armstrong Avenue and the easterly extension of Bell Avenue from Red Hill Avenue to Armstrong Avenue (see Figure 1-1). Valencia Avenue, Armstrong Avenue and Bell Avenue are four-lane secondary arterials and Warner Avenue and is a six-lane major arterial. No direct project access is assumed to Red Hill Avenue which is a six- to seven-lane major arterial and forms the border to the west. The 1-5, SR- 55 and 1-405 Freeways as well as Edinger Avenue are nearby facilities acting as regional conduits to the proposed project site. Figure 1-2 illustrates the location of the proposed project in Planning Area 1 of Tustin Legacy Neighborhood A.

As previously mentioned, the purpose of this report is to identify and evaluate how the proposed project differs from the original Specific Plan and any subsequent approved Specific Plan amendments in terms of traffic impacts. Therefore existing conditions will not be presented. Average daily traffic (ADT) and peak hour analyses will be used to verify if the proposed land use and internal circulation changes affect the off-site roadway system when compared to the project that was the subject of the approved EIR/EIS. The methodology proposed is to evaluate long- range peak hour capacity utilization at the major off-site intersections near the proposed project. The analysis in this report identifies potential impacts of the proposed project based on long-term 2035 future traffic conditions. Future traffic conditions were prepared using the Irvine Transportation Analysis Model (ITAM) and the Tustin Legacy Traffic Model (TLTM). The project site, which has been the subject of previous analyses, was last approved as part of the Specific Plan Amendment in 2010. The forecasts for the proposed project are based on the newly released ITAM 12 Year 2035 Baseline Version. For purposes of this traffic analysis, the no-project assumes that the project site contains uses according in the Specific Plan. 1.2.1 Study Area Analysis of the peripheral intersections will determine the extent of the study area (i.e., there are no significant impacts with the proposed project). The intent is to show that the overall distribution of the Legacy area traffic is similar to that estimated previously, and therefore the assumptions regarding project mitigation responsibilities remain unchanged. Previous analyses indicated that the study area defined in this traffic study as the area bounded by Valencia Avenue to the north, Armstrong Avenue to the east, Warner Avenue to the south and Red Hill Avenue to the west is sufficient limits to analyze the proposed project impacts. During the course of this study no-project versus with-project traffic forecast data were reviewed and the results were used to determine if significant or adverse project impacts occur beyond the study area boundary based on the circulation system performance criteria applied in the study. Based on the findings of the project traffic impact analysis, no expansion of the study area beyond the limits presented here is warranted. U12k]JU��� Background As previously mentioned, the traffic forecast data for the proposed project was prepared using the ITAM 12 Year 2035 Baseline version and the Tustin Legacy Traffic Model (TLTM). The ITAM traffic forecasting model is a focused sub-area model derived from the Orange County Transportation South Orange County Community College District (SOCCCD) KS v: \2073 \active \2073007510 \report \rpt.docx Stantec IM ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY Analysis Model (OCTAM 3.4 with modified OCP-201 0 socioeconomic data assumed). The OCTAM is maintained by the Orange County Transportation Authority (OCTA), and ITAM 12 has been developed according to the Orange County sub-area traffic modeling guidelines adopted by the OCTA. The OCTA has certified the ITAM traffic model as being consistent with the OCTAM regional model. The ITAM uses a 2035 time frame for traffic forecasting with corresponding assumptions with respect to local and regional transportation improvements. The TLTM is used for local access and is based on ITAM. Nearby major cumulative projects such as the Irvine Business Complex (IBC) Vision Plan and Pacific Center East project (near Edinger Avenue and Del Arno Avenue) are assumed in the background conditions as well as socioeconomic data growth projections according to the OCP- 2010 that are inherent in ITAM, and derived from OCTAM. The Tustin Legacy is assumed built out per the Specific Plan outside of the project site. 1.3 Performance Criteria In this report, a set of performance criteria is utilized to identify future level of service (LOS) deficiencies on the study area circulation system and also to define impacts and peak hour intersection capacity utilization (ICU) values of significance. According to the Highway Capacity Manual (HCM) summarized in Table 1 -1, traffic LOS is designated "A" through "IF" with LOS "A" representing free flow conditions and LOS "I" representing severe traffic congestion. The Neu intersection criteria involve the use of peak hour ICU values. The ICU ranges that correspond to LOS "A" through "F" are presented in Table 1-2. By practice, the ICU methodology assumes that intersections are signalized. LOS "D" (ICU not to exceed .90) is the performance standard for the intersections in the study area. The performance criteria presented in Table 1-3 are based on LOS calculation methodology and performance standard that have been used by the City of Tustin and by the OCTA as part of the Congestion Management Program (CMP). The performance criteria applied here is the same as used in previous traffic analyses for the area. When the project causes the intersection to exceed the performance standard (LOS "D"), mitigation is required to bring the intersection back to an acceptable level of service. If the intersection is already deficient (i.e., exceeds the performance standard) under no-project conditions and the project contributes further to the deficiency by increasing the ICU by .02 or more, mitigation is required to bring the location back to no-project level of service conditions. 1.4 References ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY Table I -I Level of Service Descriptions - Signalized Intersections Levels of service (LOS) for signalized intersections are defined in terms of control delay as follows: LOS Description LOS A describes operations with low control delay, up to 10 seconds per vehicle. This A LOS occurs when progression is extremely favorable and most vehicles arrive during the green phase. Many vehicles do not stop at all. Short cycle lengths may tend to contribute to low delay values. LOS B describes operations with control delay greater than 10 and up to 20 seconds per B vehicle. This level generally occurs with good progression, short cycle lengths, or both. More vehicles stop than the LOS A, causing higher levels of delay. LOS C describes operations with control delay greater than 20 and up to 35 seconds per vehicle. These higher delays may result from only fair progression, longer cycle lengths, C or both. Individual cycle failures may begin to appear at this level. Cycle failure occurs when a given green phase does not serve queued vehicles, and overflows occur. The number of vehicles stopping is significant at this level, though many still pass through the intersection without stopping. LOS D describes operations with control delay greater than 35 and up to 55 seconds per vehicle. At LOS D, the influence of congestion becomes more noticeable. Longer delays D may result from some combination of unfavorable progression, long cycle lengths, and high V/C ratios. Many vehicles stop, and the proportion of vehicles not stopping declines. Individual cycle failures are noticeable. LOS E describes operations with control delay greater than 55 and up to 80 seconds per E vehicle. These high delay values generally indicate poor progression, long cycle lengths, and high V/C ratios. Individual cycle failures are frequent, LOS F describes operations with control delay in excess of 80 seconds per vehicle. This level, considered unacceptable to most drivers, often occurs with oversaturation, that is, F when arrival flow rates exceed the capacity of lane groups. It may also occur at high V/C ratios with many individual cycle failures. Poor progression and long cycle lengths may also contribute significantly to high delay levels.

The proposed project is located in Planning Area 1 in Tustin Legacy Neighborhood A. This chapter describes the traffic characteristics of the proposed project including the project access points. The trip generation estimates and traffic distribution patterns associated with the proposed project are then presented. This project description information is applied in the traffic impact analysis section of this report to analyze the project under year 2035 conditions. 2.1 Project Location and Access The proposed project illustrated in Figure 2-1 is bounded by Valencia Avenue to the north, Armstrong Avenue to the east, existing Sheriff's Academy on County-owned land and Rancho Santiago Community College to the southeast, city parcel to the south/southwest and Red Hill Avenue to the west. The connection of Bell Avenue as a four-lane secondary arterial between Red Hill Avenue and Armstrong Avenue is also part of the project. Figure 2-1 also shows the preliminary ATEP access points on Bell Avenue and Valencia Avenue, all of which are full access. The primary access to the ATEP campus is assumed to be located on Valencia Avenue and Warner Avenue is the primary access for the city parcel south of ATEP. According to the 2010 Specific Plan Amendment (also referred to in this report as the "No- Project"), Bell Avenue is not extended and access to the northern uses within Neighborhood A is via Valencia Avenue and via Warner Avenue for the southern uses. Bell Avenue when extended from Red Hill Avenue to Armstrong Avenue will provide additional access to these uses. For purposes of the analysis, it is assumed that the city parcel has full access only on Warner Avenue. The district's access is dependent on the anticipated location of parking on Bell Avenue and Valencia Avenue. This analysis assumes that around 60 percent of the district's uses north of Bell Avenue access Valencia Avenue compared to 40 percent on Bell Avenue. Existing uses such as the Sheriffs Academy and Rancho Santiago Community College District will continue to operate and have access to Armstrong Avenue. 2.2 Trip Generation As previously mentioned, the project site, which has been the subject of previous traffic analyses, was last approved in 2010 as part of the Specific Plan Amendment carried out at that time. For this traffic analysis, the no-project conditions assumed for the future (year 2035) include the currently approved learning center of 893,850 square feet in ATEP and Tustin facility (essentially a bank of trips of undetermined land uses) in the city's parcel south of ATEP. The land uses that are part of the proposed project are comprised of a 51 /49 mix of learning center and office South Orange County Community College District (SOCCCD) KS vA2073\active\207300751 O\repot\rpt.docx Stantec IM O O C7 i OE dF Oj ZW m O I ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY uses. The land uses in the city's parcel are assumed as community commercial and general office uses whereas previously a special generator was identified for the parcel. The land uses and trip generation on the project site for year 2035 under no-project and with- project conditions are summarized in Table 2-1. As indicated in Table 2-1 and according to the trip generation estimates, the proposed project at buildout will generate around 2,149 AM and 2,114 PM peak hour trips and 17,932 daily trips. The with-project traffic forecasts, which includes the entire buildout of the project, results in increased trip generation differences of 1 064 AM peak hour trips, 972 PM peak hour trips and 6,241 daily trips when compared to no-project conditions. As previously mentioned, the Bell Avenue extension, which is also part of the proposed project, provides additional capacity to the surrounding circulation system allowing increases in land use intensity in the ATEP campus and the city-owned parcel south of ATEP that result in an additional 10,000 daily trips. This daily trip increase is divided equally between the city and ATEP, and although not shown in the previous table, the city's remaining trips are assumed in other parts of the Tustin Legacy. The land uses will be placed in neighborhoods that would not result in significant impacts, i.e., Neighborhood G or Planning Area 7 in Neighborhood B. 2.3 Trip Distribution Trip distribution patterns for the project site were developed using the ITAM traffic model and are presented in Figure 2-2 for year 2035. The trip distribution patterns are based on the model's 00 distribution of daily project traffic. These percentages differ slightly in the peak hours, and the traffic model uses the individual peak hour distribution patterns to assign peak hour trips.

The potential traffic impacts of the project are assessed based on a comparison of 2035 no-project and with-project conditions. 3.1 Year 2035 Traffic Impacts As discussed in Chapter 1.0, the recent release of the Irvine Transportation Analysis Model Version 12 (ITAM 12) and the Tustin Legacy Traffic Model (TLTM) were used to prepare the year 2035 no-project and with-project traffic forecasts that are applied in the analysis. The following sub-sections summarize the resulting 2035 no-project and with-project traffic conditions for arterial roads and intersections. 3.1.1 Average Daily Traffic Volumes Year 2035 no -project and with -project average daily traffic (ADT) volumes are illustrated in Figure 3-1. The introduction of Bell Avenue as a four-lane secondary is beneficial to the circulation system surrounding the project site. It provides additional east-west capacity parallel to Warner Avenue and Valencia Avenue thereby relieving traffic along these roadways. The additional capacity allows increased intensity in the Advanced Technology and Education Park (ATEP) campus as well as in the city's parcel south of ATEP. The highest volume increase with the project is 9,000 ADT on Red Hill Avenue just north of Bell Avenue which increases from 33,000 to 42,000 ADT well within the capacity of a six-lane major arterial. The highest volume decrease with the project occurs on Warner Avenue just east of Red Hill Avenue which decreases from 32,000 to 24,000 ADT. 3.1.2 Peak Hour intersection Levels of Service Figures 3-2 and 3-3 illustrate the year 2035 no-project and with-project AM and PM peak hour volumes at the intersections analyzed in the study area. The 2035 peak hour volumes along with the corresponding future lane configurations for the intersections analyzed (see Figures 3-4 and 3- 5) result in the intersection capacity utilization (ICU) values summarized in Table 3-1 (ICU calculation worksheets are included in Appendix A). Based on the intersection LOS performance criteria and impact thresholds outlined in Chapter 1 .0, no intersection location analyzed in the study area is adversely impacted by the proposed project in the year 2035 ICU analysis (i.e., all intersections with the project are forecast to operate at level of service "D" (LOS D) or better), South Orange County Community College District (SOCCCD) KS v:\2073\acfive\207300751 O\report\rpt.docx Stantec El w W� LWJM w m NE ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY Table 3-1 2035 Intersection LOS Summary 1.

The first subject covers the qualitative analysis of an all-academic alternative to the Advanced Technology and Education Park (ATEP) campus instead of a mix of academic and office. The second subject covers the potential impacts of the two intersections changed or formed by the extension of Bell Avenue from its existing terminus at Red Hill Avenue to Armstrong Avenue. The evaluation of the two intersections includes determining the need for signalization and left-turn storage length requirements. 4.1 ATEP Academic Alternative In the event that South Orange County Community College District (SOCCCD) builds the ATEP site as all-academic rather than a mix of academic/general office, the square footage of the learning center would be higher assuming that the trip generation is equivalent to the ATEP academic/general office project mix. In addition to different square footage, the peak hour volumes also differ (see Table 4-1). However the difference is opposite. The peak hour volumes are lower for an all-academic use at ATEP compared to a project with academic/general office mix. It can be concluded, that the findings presented in the previous chapter would still apply if the uses at ATEP change from academic and general office to all-academic. 4.2 Bell Avenue Two intersections change or form when Bell Avenue is extended from its existing terminus at Red Hill Avenue to Armstrong Avenue. An evaluation is carried out at these two intersections which includes determining the need for signalization and left-turn storage length requirements. 4.2.1 Signallization Traffic signal warrants based on peak hour volumes as adopted by the Federal Highway Administration and Caltrans were used here to determine the need for signalization. In applying this warrant, the volumes of both the major and minor street must meet or exceed those shown on the curves in Figures 4-1 and 4-2 for rural and urban conditions, respectively. Determining the major street approach for the signal warrant involves calculating the number of vehicles approaching the intersection on both major street legs. The highest total volume for either the continuous east and west approach or the north and south approach during either AM and PM is determined to be the major street approach for both peak hours. The minor street peak hour signal warrant volume is the number of peak hour vehicles approaching the intersection on only the highest volume leg. The highest volume for either the AM or PM determines the minor approach for both peak hours, South Orange County Community College District (SOCCCD) KS v: \2073 \active \2073007510 \report \rpt.d0cx Stantec ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY Table 4-1 ATEP Project Alternative Trip Generation Comparison South Orange County Community College District (SOCCCD) KS v: \2073 \active \2073007510 \report \rpt.docx Stantec FIBER.

Warrants are based on rural when the speed on the major street is 40 miles per hour (mph) or higher. For urban areas, the speed on the major street is 35 mph or lower. The two Bell Avenue intersections in the study area are analyzed here for year 2035 conditions, The warrants at the Red Hill Avenue and Bell Avenue intersection are based on rural due to the higher speeds along Red Hill Avenue. Lower speeds are expected on Armstrong Avenue therefore the signal warrant analysis at the Armstrong Avenue and Bell Avenue intersection is based on urban. The signal warrant analysis for 2035 with project conditions is summarized in Table 4-2, and based on the application of the warrant, both intersections require traffic signals. Typically, signals are not installed until signal warrants are met. 4.2.2 Left -Turn Storage Left-turn pocket lengths at the two Bell Avenue intersections for new left -turn movements were estimated based on the highest peak hour volume under year 2035 conditions previously presented in Figure 3-3. Where pocket lengths exceed the standard 150 feet for public roadways, the length is based on one foot per peak hour left-turn volume (highest of AM and PM) and rounded into increments of 10. The worst-case estimated left-turn storage length requirements for the intersections analyzed are summarized in Table 4-3. It should be noted that the storage length requirement could be minimized with special signal treatments such as two left-turn phases (i.e., both at the beginning and end of the signal cycle).

The purpose of this report was to identify and evaluate how the proposed project differs from the original Specific Plan and any subsequent approved Specific Plan amendments in terms of traffic impacts pursuant to City-adopted California Environmental Quality Act (CEQA) thresholds of significance. The traffic study is in support of the Specific Plan Amendment and is a Supplemental to the previously approved EIR/EIS carried out for Tustin Legacy. The Specific Plan land uses and the circulation system that were assumed in previous Tustin Legacy studies outside the proposed project site as carried out for the 2010 Specific Plan Amendment are included here. The traffic impacts of the proposed project in Neighborhood A in Tustin Legacy were identified by analyzing the traffic conditions for the study area circulation system based on year 2035 time frame. In each case, traffic conditions under no-project and with-project were compared to identify the potential traffic impacts of the project. The project site assumes the current approval (from the 2010 Specific Plan Amendment) for the site under year 2035 no-project conditions, and the proposed project changes are assumed to be fully developed under year 2035 with-project conditions including the extension of Bell Avenue to Armstrong Avenue. The circulation system performance criteria applied in the analysis are based on level of service (LOS) calculation methodologies and performance standards for intersections that have been used by previous reports in the Tustin Legacy. The results of the year 2035 project impact analysis, which are presented in detail in Chapter 3.0 of this report, indicate that the proposed project is not forecast to significantly impact any intersections in the study area (see Table 3-1). Therefore no project mitigation measures are required The intersection LOS summaries presented in Chapter 3.0 indicated that enough capacity is available to accommodate the proposed project with all intersections operating at LOS "D" or better in the study area. The results of the analysis presented in Chapter 4.0 indicate that the proposed project meets the requirements for site access including the lane geometry at the new Bell Avenue intersections. Adequate design of these two intersections and the Bell Avenue extension itself will accommodate the proposed project with no adverse traffic conditions on other parts of the circulation system.

Intersection location reference map is provided in Figure A-1 for the project study area. The AM and PM peak hour intersection capacity utilization (ICU) worksheets for year 2035 no-project and with-project conditions future traffic analysis scenarios analyzed in the study area are presented in the following order by intersection: .. F-1 = The ICU calculation procedure is based on a critical movement methodology that shows the amount of capacity utilized by each critical movement at an intersection. A capacity of 1,700 vehicles per hour per lane is assumed together with a .05 clearance interval. A "de facto" right- turn lane is used in the ICU calculation for cases where a curb lane is wide enough to separately serve both through and right-turn traffic (typically with a width of 19 feet or more from curb to outside of through-lane with parking prohibited during peak periods). Such lanes are treated the same as striped right-turn lanes during the ICU calculations, but they are denoted on the ICU calculation worksheets using the letter "d" in place of a numerical entry for right-turn lanes. The methodology also incorporates a check for right-turn capacity utilization. Both right-turn-on- green (RTOG) and right-turn-on-red (RTOR) capacity availability are calculated and checked against the total right-turn capacity need. If insufficient capacity is available, then an adjustment is made to the total capacity utilization value. The following example shows how this adjustment is made. I 1. Right-Turn-On-Green (RTOG) If NBT is critical move, then: RTOG = V/C (NBT) Otherwise, RTOG = V/C (NBL) + V/C (SBT) - V/C (SBQ VAIII[mi If WBL is critical move, then: RTOR = V/C (WBQ Otherwise, RTOR = V/C (EBL) + V/C (WBT) - V/C (EBT) South Orange County Community College District (SOCCCD) KS v:\2073\active\207300751 O\report\rpt.docx Stantec ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY 3. Right-Turn Overlap Adjustment If the northbound right is assumed to overlap with the adjacent westbound left, adjustments to the RTOG and RTOR values are made as follows: RTOG = RTOG + V/C (WBQ RTOR = RTOR - V/C (WBL) 4. Total Right-Turn Capacity (RTC) Availability For NBR RTC = RTOG + factor x RTOR Where factor = RTOR saturation flow factor (75%) Right-turn adjustment is then as follows: Additional ICU = V/C (NBR) — RTC A zero or negative value indicates that adequate capacity is available and no adjustment is necessary. A positive value indicates that the available RTOR and RTOG capacity does not adequately accommodate the right-turn V/C, therefore the right-turn is essentially considered to be a critical movement. In such cases, the right-turn adjustment is noted on the ICU worksheet and it is included in the total capacity utilization value. When it is determined that a right-turn adjustment is required for more than one right-turn movement, the word "multi" is printed on the worksheet instead of an actual right-turn movement reference, and the right-turn adjustments are cumulatively added to the total capacity utilization value. In such cases, further operational evaluation is typically carried out to determine if under actual operational conditions, the critical right-turns would operate simultaneously, and therefore a right-turn adjustment credit should be applied. Shared Lane VZC Methodology For intersection approaches where shared usage of a lone is permitted by more than one turn movement (e.g., left/through, through/right, left/through/right), the individual turn volumes are evaluated to determine whether dedication of the shared lane is warranted to any one given turn movement. The following example demonstrates how this evaluation is carried out: Example for Shared Left /Through Lane 1. Average Lane Volume (ALV) ALV = Left -Turn Volume + Through Volume Total Left + Through Approach Lanes (including shared lane) 2. ALV for Each Approach ALV (Left) = Left -Turn Volume Left Approach Lanes (including shared lane) South Orange County Community College District (SOCCCD) KS v:\2073\octive\207300751 0\report\rpf.docx Stantec IM ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY ALV (Through) = Through Volume Through Approach Lanes (including s are ane) 3. Lane Dedication is Warranted If ALV (Left) is greater than AN then full dedication of the shared lane to the left -turn approach is warranted. Left -turn and through V/C ratios for this case are calculated as follows: V/C (Left) = Left -Turn Volume Left Approach Capacity (including shared lane) V/C (Through) = Through Volume Through Approach Capacity (excluding shared lane) Similarly, if ALV (Through) is greater than ALV then full dedication to the through approach is warranted, and left -turn and through V/C ratios are calculated as follows: V/C (Left) = Left -Turn Volume Left Approach Capacity (excluding shared lane) V/C (Through) = Through Volume Through Approach Capacity (including shared lane) 4. Lane Dedication is not Warranted If ALV (Left) and AN (Through) are both less than ALV, the left /through lane is assumed to be truly shared and each left, left /through or through approach lane carries an evenly distributed volume of traffic equal to ALV. A combined left /through V/C ratio is calculated as follows: V/C (Left /Through) = Left -Turn Volume + Through Volume Total Left + Through Approach Capacity (including shared lane) This V/C (Left /Through) ratio is assigned as the V/C (Through) ratio for the critica movement analysis and ICU summary listing. If split phasing has not been designated for this approach, the relative proportion of V/C (Through) that is attributed to the left -turn volume is estimated as follows: If approach has more than one left -turn (including shared lane), then: V/C (Left) = V/C (Through) If approach has only one left -turn lane (shared lane), then: South Orange County Community College District (SOCCCD) KS v:\2073\active\207300751 0 \report \rpt.docx Stantec aYe^ SEEM M M ADVANCED TECHNOLOGY AND EDUCATION PARK (ATEP) TRAFFIC STUDY V/C (Left) = Left-Turn Volume Single Approach Lane Capacity If this left-turn movement is determined to be a critical movement, the V/C (Left) value is posted in brackets on the ICU summary printout. These same steps are carried out for shared through/right lanes. If full dedication of a shared through/right lane to the right-turn movement is warranted, the right-turn V/C value calculated in step three is checked against the RTOR and RTOG capacity, When an approach contains more than one shared lane (e.g., left/through and through/right), steps one and two listed above are carried out for the three turn movements combined. Step four is carried out if dedication is not warranted for either of the shared lanes.

It creates cool summers, mild winters, and infrequent rainfall. It drives the cool daytime sea breeze, and it maintains comfortable humidity levels and ample sunshine after the frequent morning clouds dissipate. Unfortunately, the same atmospheric processes that create the desirable living climate combine to restrict the ability of the atmosphere to disperse the air pollution generated by the large population attracted in part by the desirable climate. Portions of the Los Angeles Basin therefore experience some of the worst air quality in the nation for certain pollutants. The City of Tustin has an annual average temperature high of 76 degrees and a low of 60 degrees. Daily and seasonal oscillations of temperature are small because of the moderating effects of the nearby oceanic thermal reservoir. In contrast to the steady temperature regime, rainfall is highly variable. Measurable precipitation occurs mainly from early November to mid - April, but total amounts are generally small. Tustin averages 13 inches of rain annually with January as the wettest month. Winds in the project vicinity display several characteristic regimes. During the day, especially in summer, winds are from the south in the morning and from the west in the afternoon. Daytime wind speeds are 7 — 9 miles per hour on average. At night, especially in winter, the land P p � � � p Y becomes cooler than the ocean, and an offshore wind of 3 -5 miles per hour develops. Early morning winds are briefly from the southeast parallel to the coastline before the daytime on- shore flow becomes well established again. One other important wind regime occurs when high pressure occurs over the western United States that creates hot, dry and gusty Santa Ana winds from the north and northeast across Tustin. The net effect of the wind pattern on air pollution is that any locally generated emissions will be carried offshore at night and toward inland Orange County by day. Daytime ventilation is much more vigorous. Unless daytime winds rotate far into the north and bring air pollution from developed areas of the air basin into Tustin, warm season air quality is much better in the project vicinity than in inland valleys of the air basin. Both summer and winter air quality in the project area is generally good. h1 addition to winds that control the rate and direction of pollution dispersal, Southern California is notorious for strong temperature inversions that limit the vertical depth through which pollution can be mixed. In summer, coastal areas are characterized by a sharp discontinuity between the cool marine air at the surface and the warm, sinking air aloft within the high pressure cell over the ocean to the west. This marine /subsidence inversion allows for good local mixing, but acts like a giant lid over the basin. Air starting onshore at the beach is relatively clean, but becomes progressively more polluted as sources continue to add pollution from below without any dilution from above. Because of Tustin's location relative to the ocean, the incoming marine air during warm season onshore flow contains little air pollution. Local air quality is not substantially affected by the regional subsidence inversions. Bell Ave, Tusty AQ GHG I ME n -ms on clear, winter nights when cold air off the mountains sinks to A second inversion type fo the surface while the air aloft remains warm. This process forms radiation inversions. These inversions, in conjunction with very light winds, trap pollutants such as automobile exhaust near their source. During the long nocturnal drainage flow from land to sea, the exhaust pollutants continually accumulate within the shallow, cool layer of air near the ground. Some areas of Orange County thus may experience elevated levels of carbon monoxide and nitrogen oxides because of this winter radiation inversion condition. However, the coastal areas of Orange County have not substantially been affected by limited nocturnal mixing effects (no elevated levels of CO) in approximately 10 years. Both types of inversions occur throughout the year to some extent, but the marine inversions are very dominant during the day in summer, and radiation inversions are much stronger on winter nights when nights are long and air is cool. The governing role of these inversions in atmospheric dispersion leads to a substantially different air quality environment in summer in the South Coast Air Basin than in winter. Belt A, =e, Tustui AQ =GHG ON, AIR QUALITY SETTING Oil AMBIENT AIR QUALITY STANDARDS (AAQS) In order to gauge the significance of the air quality impacts of the proposed ATEP Bell Avenue project, those impacts, together with existing background air quality levels, must be compared to the applicable ambient air quality standards. These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those people most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise, called "sensitive receptors." Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed. Recent research has shown, however, that chronic exposure to ozone (the primary ingredient in photochemical smog) may lead to adverse respiratory health even at concentrations close to the ambient standard. National AAQS were established in 1971 for six pollution species with states retaining the option to add other pollutants, require more stringent compliance, or to include different exposure periods. The initial attainment deadline of 1977 was extended several times in air quality problem areas like Southern California. In 2003, the Environmental Protection Agency (EPA) adopted a rule, which extended and established a new attainment deadline for ozone for the ROOM year 2021. Because the State of California had established AAQS several years before the federal action and because of unique air quality problems introduced by the restrictive dispersion meteorology, there is considerable difference between state and national clean air standards. Those standards currently in effect in California are shown in Table 1. Sources and health effects of various pollutants are shown in Table 2. The Federal Clean Air Act Amendments (CAAA) of 1990 required that the U.S. Environmental Protection Agency (EPA) review all national AAQS in light of currently known health effects. EPA was charged with modifying existing standards or promulgating new ones where appropriate. EPA subsequently developed standards for chronic ozone exposure (8+ hours per day) and for very small diameter particulate matter (called "PM-2.5"). New national AAQS were adopted in 1997 for these pollutants. Planning and enforcement of the federal standards for PM-2.5 and for ozone (8-hour) were challenged by trucking and manufacturing organizations. In a unanimous decision, the U.S. Supreme Court ruled that EPA did not require specific congressional authorization to adopt national clean air standards. The Court also ruled that health-based standards did not require preparation of a cost-benefit analysis. The Court did find, however, that there was some inconsistency between existing and "new" standards in their required attainment schedules. Such attainment-planning schedule inconsistencies centered mainly on the 8-hour ozone standard. EPA subsequently agreed to downgrade the attainment designation for a large number of communities to "non-attainment" for the 8-hour ozone standard. Milli Bell Aw.

Sell Ave, Tustui AQ,GHG Evaluation of the most current data on the health effects of inhalation of fine particulate matter prompted the California Air Resources Board (ARB) to recommend adoption of the statewide IN PM-2.5 standard that is more stringent than the federal standard. This standard was adopted in I 2002. The State PM-2.5 standard is more of a goal in that it does not have specific attainment 013 planning requirements like a federal clean air standard, but only requires continued progress towards attainment. Similarly, the ARB extensively evaluated health effects of ozone exposure. A new state standard for an 8-hour ozone exposure was adopted in 2005, which aligned with the exposure period for the federal 8-hour standard. The California 8-hour ozone standard of 0.07 ppm is more stringent than the federal 8-hour standard of 0.075 ppm. The state standard, however, does not have a specific attainment deadline. California air quality jurisdictions are required to make steady progress towards attaining state standards, but there are no hard deadlines or any consequences of non-attainment. During the same re-evaluation process, the ARB adopted an annual state standard for nitrogen dioxide (NO,) that is more stringent than the corresponding federal standard, and strengthened the state one-hour NO2 standard. As part of EPA's 2002 consent decree on clean air standards, a further review of airborne particulate matter (PM) and human health was initiated. A substantial modification of federal clean air standards for PM was promulgated in 2006. Standards for PM-2.5 were strengthened, a new class of PM in the 2.5 to 10 micron size was created, some PM-10 standards were revoked, and a distinction between rural and urban air quality was adopted. In December, 2012, the 3 federal annual standard for PM-2.5 was reduced from 15 µg/m3 to 12 pglru which matches the California AAQS. The severity of the basin's non-attainment status for PM-2.5 may be increased by this action and thus require accelerated planning for future PM-2.5 attainment. In response to continuing evidence that ozone exposure at levels just meeting federal clean air - standards is demonstrably unhealthful, EPA had proposed a further strengthening of the 8-hour standard. Draft standards were published. The proposed future 8-hour standard was 0.065 ppm. Environmental organizations generally praised this proposal. Most manufacturing, transportation or power generation groups opposed the new standard as economically unwise in an uncertain fiscal climate. In response to these concerns, the revision to the 8-hour federal ozone standard was placed on indefinite hold. A new federal one-hour standard for nitrogen dioxide (NO-,) has also recently been adopted which is more stringent than the existing state standard. Despite the additional stringency of the federal NO,) standard, air quality monitoring data in the South Coast Air Basin (SCAB) suggests that this standard is met in the region. The federal primary standard for sulfur dioxide (SO2) were similarly modified in 2010. Because California requires use of lower sulfur fuel and burns negligible amounts of sulfur-bearing coal, SO, is not a problem pollutant in the State. Betl Awe, Tusui AQ GHG SENIOR 4- BASELINE AIR QUALITY Existing and probable future levels of air quality in the project area can be best inferred from ambient air quality measurements conducted by the SCAQMD at its Costa Mesa monitoring station on Verde Drive. This station monitors most pollutants such as smog, as well as primary vehicular pollutants such as carbon monoxide. Respirable particulate air pollution is not monitored at Costa Mesa. The nearest representative station monitoring station for particulates is at the Mission Viejo monitoring station at 26081 Via Para. Table 3 summarizes the last six years of published data from these resources. The following conclusions can be drawn from this data: a. Photochemical smog (ozone) levels infrequently exceeds standards. The 1-hour state ozone standard has been exceeded only once in all days in the past six years near Costa Mesa while the 8-hour state standard has been violated an on less than one percent of all days. b. Measurements of carbon monoxide and nitrogen dioxide indicate low baseline levels in comparison to the most stringent standards. c. Respirable dust (PM-10) levels only rarely exceed the state standard, while the less stringent federal PM -10 standard has not been violated since PM -10 measurements began at Mission Viejo, M d. The federal ultra-fine particulate (PM-2.5) standard of 35 µg/m, has been exceeded less than one percent of measurement days (four times in the last six years). Although complete attainment of every clean air standard is not yet imminent, extrapolation of the steady improvement trend suggests that such attainment could occur within the reasonably near future.

The SCAB could not meet the deadlines for ozone, nitrogen dioxide, carbon monoxide, or PM-10. In the SCAB, the agencies designated by the governor to develop regional air quality plans are the SCAQMD and the Southern California Association of Governments (SCAG). The two agencies first adopted an Air Quality Management Plan (AQMP) in 1979 and revised it several times as earlier attainment forecasts were shown to be overly optimistic. The 1990 Federal Clean Air Act Amendment (CAAA) required that all states with air-sheds with "serious" or worse ozone problems submit a revision to the State Implementation Plan (SIP), Amendments to the SIP have been proposed, revised and approved over the past decade. The most current regional attainment emissions forecast for ozone precursors (ROG and NOx) and for carbon monoxide (CO) and for particulate matter are shown in Table 4. Substantial reductions in emissions of ROG, NOx and CO are forecast to continue throughout the next several decades. Unless new particulate control programs are implemented, PM-10 and PM-2.5 are forecast to slightly increase. N The Air Quality Management District (AQMD) adopted an updated clean air "blueprint" in August 2003. The 2003 Air Quality Management Plan (AQMP) was approved by the EPA in 2004. The AQMP outlined the air pollution measures needed to meet federal health-based standards for ozone by 2010 and for particulates (PM -10) by 2006. The 2003 AQMP was based upon the federal one-hour ozone standard which was revoked late in 2005 and replaced by an 8- hour federal standard. Because of the revocation of the hourly standard, a new air quality planning cycle was initiated. With re-designation of the air basin as non-attainment for the 8-hour ozone standard, a new attainment plan was developed. This plan shifted most of the one-hour ozone standard attainment strategies to the 8-hour standard. As previously noted, the attainment date was to "slip" from 2010 to 2021. The updated attainment plan also includes strategies for ultimately meeting the federal PM-2.5 standard. Because projected attainment by 2021 requires control technologies that do not exist yet, the SCAQMD requested a voluntary "bump-up" from a "severe non-attainment" area to an "extreme non-attainment" designation for ozone. The extreme designation will allow a longer time period for these technologies to develop. If attainment cannot be demonstrated within the specified deadline without relying on "black-box" measures, EPA would have been required to impose sanctions on the region had the bump-up request not been approved. In April 2010, the EPA approved the change in the non-attainment designation from "severe-17" to "extreme," This reclassification sets a later attainment deadline, but also requires the air basin to adopt even more stringent emissions controls.

'With current emissions reduction programs and adopted growth forecasts. Source: California Air Resources Board, California Emissions Projection Analysis Model, 2009 In other air quality attainment plan reviews, EPA has disapproved part of the SCAB PM -2.5 attainment plan included in the AQNIP. EPA has stated that the current attainment plan relies on PM -2.5 control regulations that have not yet been approved or implemented. It is expected that a NINE number of rules that are pending approval will remove the identified deficiencies. If these issues RINSE- are not resolved within the next several years, federal funding sanctions for transportation projects could result. The 2012 AQNIP update that was recently adopted by the SCAQMD focuses heavily on PM-2.5 control and is expected to remedy identified PM -2.5 planning deficiencies. Projects such as the proposed ATEP Bell Avenue do not directly relate to the AQNIP in that there are no specific air quality programs or regulations governing general development. Conformity with adopted plans, forecasts and programs relative to population, housing, employment and land use is the primary yardstick by which impact significance of planned growth is determined. The SCAQNID, however, while acknowledging that the AQNIP is a growth- accommodating document, does not favor designating regional impacts as less-than- significant just because the proposed development is consistent with regional growth projections. Air quality impact significance for the proposed project has therefore been analyzed on a project- specific basis. Bell Ave, Tustin AQ,GHG AIR QUALITY IMPACT STANDARDS OF SIGNIFICANCE Air quality impacts are considered "significant" if they cause clean air standards to be violated where they are currently met, or if they "substantially" contribute to an existing violation of standards. Any substantial emissions of air contaminants for which there is no safe exposure, or nuisance emissions such as dust or odors, would also be considered a significant impact. Appendix G of the California CEQA Guidelines offers the following five tests of air quality impact significance. A project would have a potentially significant impact if it: a. Conflicts with or obstructs implementation of the applicable air quality plan. b. Violates any air quality standard or contributes substantially to an existing or projected air quality violation. c. Results in a cumulatively considerable net increase of any criteria pollutants for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors). d. Exposes sensitive receptors to substantial pollutant concentrations. e. Creates objectionable odors affecting a substantial number of people. Primary Pollutants Air quality impacts generally occur on two scales of motion. Near an individual source of emissions or a collection of sources such as a crowded intersection or parking lot, levels of those pollutants that are emitted in their already unhealthful form will be highest. Carbon monoxide (CO) is an example of such a pollutant. Primary pollutant impacts can generally be evaluated directly in comparison to appropriate clean air standards. Violations of these standards where they are currently met, or a measurable worsening of an existing or future violation, would be considered a significant impact. Many particulates, especially fugitive dust emissions, are also primary pollutants. Because of the non-attainment status of the South Coast Air Basin (SCAB) for PM-10, an aggressive dust control program is required to control fugitive dust during project construction. Secondary Pollutants Many pollutants, however, require time to transform from a more benign form to a more unhealthful contaminant. Their impact occurs regionally far from the source. Their incremental regional impact is minute on an individual basis and cannot be quantified except through complex photochemical comvuter models. Analvsis of siLynific2nre of such omk6niiz ;, hqci-ti s Bell.k,e, Tusthi AQGHG upon a specified amount of emissions (pounds, tons, etc.) even though there is no way to translate those emissions directly into a corresponding ambient air quality impact. Because of the chemical complexity of primary versus secondary pollutants, the SCAQMD has designated significant emissions levels as surrogates for evaluating regional air quality impact significance independent of chemical transformation processes. Projects with daily emissions that exceed any of the following emission thresholds are recommended by the SCAQMD to be considered significant under CEQA guidelines.

OEM I'M Additional Indicators In its CEQA Handbook, the SCAQMD also states that additional indicators should be used as screening criteria to determine the need for further analysis with respect to air quality. The additional indicators are as follows: • Project could interfere with the attainment of the federal or state ambient air quality standards by either violating or contributing to an existing or projected air quality violation • Project could result in population increases within the regional statistical area which would be in excess of that projected in the AQMP and in other than planned locations for the project's build-out year. • Project could generate vehicle trips that cause a CO hot spot. The SCAQMD CEQA Handbook also identifies various secondary significance criteria related to toxic, hazardous or odorous air contaminants. Except for the small diameter particulate matter ("PM-2.5") fraction of diesel exhaust generated by heavy construction equipment, there are no secondary impact indicators associated with project construction and operational roadway use. Bell Ave.. Team AQiGHG -11- For PM-2.5 exhaust emissions, recently adopted policies require the gr adual conversion of delivery fleets to diesel alternatives, or the use of "clean" diesel if their emissions are demonstrated to be as low as those from alternative fuels. Because health risks from toxic air contaminants (TAC's) are cumulative over an assumed 70-year lifespan, measurable off-site public health risk from diesel TAC exposure would occur for only a brief portion of a project lifetime, and only in dilute quantity. SENSITIVE RECEPTORS Air quality impacts are analyzed relative to those persons with the greatest sensitivity to air pollution exposure. Such persons are called "sensitive receptors." Sensitive population groups include young children, the elderly and the acutely and chronically ill (especially those with cardio-respiratory disease). Residential areas adjacent to a proposed site are considered to be sensitive to air pollution exposure because they may be occupied for extended periods, and residents may be outdoors when exposure is highest. The Orange County Rescue Mission, which contain religious based temporary transitional housing units for the homeless, as well as public and private transitional housing units northeast of the ATEP campus, are considered the closest sensitive receptors. CONSTRUCTION ACTIVITY IMPACTS Dust is typically the primary concern during construction of new buildings. Because such 0- emissions are not amenable to collection and discharge through a controlled source, they are called "fugitive emissions." Emission rates vary as a function of many parameters (soil silt, soil moisture, wind speed, area disturbed, number of vehicles, depth of disturbance or excavation, etc.). These parameters are not known with any reasonable certainty prior to project development and may change from day to day. Any assignment of specific parameters to an unknown future date is speculative and conjectural. Because of the inherent uncertainty in the predictive factors for estimating fugitive dust generation, regulatory agencies typically use one universal "default" factor based on the area disturbed assuming that all other input parameters into emission rate prediction fall into midrange average values. This assumption may or may not be totally applicable to site-specific conditions on the proposed project site. As noted previously, emissions estimation for project- specific fugitive dust sources is therefore characterized by a considerable degree of imprecision. Average daily PM-10 emissions during site grading and other disturbance are shown estimated to be about 10 pounds per acre. This estimate presumes the use of reasonably available control measures (RACMs). The SCAQMD requires the use of best available control measures (BACMs) for fugitive dust from construction activities. Current research in particulate- exposure health suggests that the most adverse effects derive from ultra-small diameter particulate matter comprised of chemically reactive pollutants such as sulfates, nitrates or organic material. A national clean air standard for particulate matter of 2.5 microns or smaller in diameter (called "PM-2.5") was adopted in 1997. A limited amount of Bell A,,-, Tusthi AQ'GHG construction activity particulate matter is in the PM-2.5 range. PM-2.5 emissions are estimated to comprise 10-20 percent of PM-10. NO In addition to fine particles that remain suspended in the atmosphere semi - indefinitely RION- construction activities generate many larger particles with shorter atmospheric residence times. This dust is comprised mainly of large diameter inert silicates that are chemically non-reactive and are further readily filtered out by human breathing passages. These fugitive dust particles are therefore more of a potential soiling nuisance as they settle out on parked cars, outdoor furniture or landscape foliage rather than any adverse health hazard. CalEEMod was developed by the SCAQMD to provide a model by which to calculate both construction emissions and operational emissions from a variety of land use projects. It calculates both the daily maximum and annual average emissions for criteria pollutants as well as total or annual greenhouse gas (GHG) emissions. Although exhaust emissions will result from on and off-site heavy equipment, the exact types and numbers of equipment will vary among contractors such that such emissions cannot be quantified with certainty. Estimated construction emissions were modeled using CalEEMod201 1. 1.1 to identify maximum daily emissions for each pollutant during project construction. Construction emissions include all emissions associated with the construction equipment, worker trips, and on-road diesel trucks. The Bell Avenue roadway extension was modeled separately from the proposed structural IM M facilities. The Bell Avenue extension was modeled as an "asphalt surface" to ensure off - Basing MEMO emissions are accounted for. 0 The project proposes a total of 194,109 square feet of construction (modeled in this study as a 2- year college and office use) over the project lifetime. Although build-out is not anticipated to occur all at once, modeling as such provides a worst case estimate as all emissions are condensed into a single intense period of activity. If daily construction emissions thresholds are not exceeded for this condensed scenario, then more piecemeal construction activity, spread out over a possible 20 year time frame will not exceed emissions thresholds.

Bell Ave, Tustai AQ GHG Construction equipment exhaust contains carcinogenic compounds within the diesel exhaust particulates. The toxicity of diesel exhaust is evaluated relative to a 24-hour per day, 365 days per year, 70-year lifetime exposure. The SCAQMD does not generally require the analysis of construction-related diesel emissions relative to health risk due to the short period for which the majority of diesel exhaust would occur. Health risk analyses are typically assessed over a 9-, 30-, or 70-year timeframe and not over a relatively brief period due to the lack of health risk associated with such a brief exposure. Activity over a large area as proposed by this project will operate for only a small number of days near any possible sensitive receptor. Because diesel exhaust exposure health risk is a cumulative lifetime effect, the few days of concentrated exposure has minimal impact when diluted over a full lifetime. OPERATIONAL IMPACTS The proposed project, including both SOCCCD and City development, would produce up to 10,000 average daily trips (ADT) from full occupancy and vehicular travel, in excess of the vehicle trips previously analyzed by other environmental documents. Commercial uses also generate small quantities of area source emissions derived from organic compounds from cleaning products, landscape maintenance, etc. The contribution of these sources is incorporated into the analysis below. Operational emissions for proposed uses were calculated using CalEEMod 2011.1.1. for an F71 assumed project build-out year of 2020 for the and are shown in Table 10.

Nevertheless, mitigation through enhanced dust control measures is recommended for use because of the non-attainment status of the air basin and because of the proximity of existing homes. Recommended mitigation includes: Fugitive Dust Control • Suspend the use of all construction equipment during first-stage smog alerts. • Apply soil stabilizers or moisten inactive areas. • Prepare and 11,11plement a high wind dust control plan. • Stabilize previously disturbed areas if subsequent construction is delayed. • Apply water three times daily, or non-toxic soil stabilizers according to manufacturers' specifications, to all unpaved parking or staging areas, unpaved road surfaces, and active construction areas. • Cover all stock piles with tarps at the end of each day or as needed. • Provide water spray during loading and unloading of earthen materials. • Minimize in-out traffic from construction zone • Cover all trucks hauling dirt, sand, or loose material or require all trucks to maintain at least two feet of freeboard • Sweep streets daily if visible soil material is carried out from the construction site Similarly, ozone precursor emissions (ROG and NOx) are calculated to be below SCAQMD CEQA thresholds. However, because of the non-attainment for photochemical smog, the use of reasonably available control measures for diesel exhaust is recommended. Combustion emissions control includes: Exhaust Emissions Control • Utilize well-tuned off-road construction equipment. • Establish a preference for contractors using Tier 3 or better heavy equipment. • Enforce 5- minute idling limits for both on-road trucks and off-road equipment. Bell Aw. Tusthi AQ,GHG .»_ "Greenhouse gases" (so called because of their role in trapping heat near the surface of the earth) emitted by human activity are implicated in global climate change, commonly referred to as "global warming." These greenhouse gases contribute to an increase in the temperature of the earth's atmosphere by transparency to short wavelength visible sunlight, but near opacity to outgoing terrestrial long wavelength heat radiation in some parts of the infrared spectrum. The principal greenhouse gases (GHGs) are carbon dioxide, methane, nitrous oxide, ozone, and water vapor. For purposes of planning and regulation, Section 15364.5 of the California Code of Regulations defines GHGs to include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. Fossil fuel consumption in the transportation sector (on-road motor vehicles, off-highway mobile sources, and aircraft) is the single largest source of GHG emissions, accounting for approximately half of GHG emissions globally. Industrial and commercial sources are the second largest contributors of GHG emissions with about one-fourth of total emissions. California has passed several bills and the Governor has signed at least three executive orders regarding greenhouse gases. GHG statues and executive orders (EO) include AB 32, SB 13368, EO 5-03-05, EO 5 -20-06 and EO 5-01-07. AB 32 is one of the most significant pieces of environmental legislation that California has adopted. Among other things, it is designed to maintain California's reputation as a "national and international leader on energy conservation and environmental stewardship." It will have wide-ranging effects on California businesses and lifestyles as well as far reaching effects on other states and countries. A unique aspect of AB 32, beyond its broad and wide-ranging mandatory provisions and dramatic GHG reductions are the short time frames within which it must be implemented. Major components of the AB 32 include: • Require the monitoring and be reporting g of GHG emissions inning with sources or 9 categories of sources that contribute the most to statewide emissions. • Requires immediate "early action" control programs on the most readily controlled GHG sources. • Mandates that by 2020, California's GHG emissions be reduced to 1990 levels. • Forces an overall reduction of GHG gases in California by 25-40%, from business as usual, to be achieved by 2020. • Must complement efforts to achieve and maintain federal and state ambient air quality standards and to reduce toxic air contaminants. Statewide, the framework for developing the implementing regulations for AB 32 is under way. Maximum GHG reductions are expected to derive from increased vehicle fuel efficiency, from greater use of renewable energy and from increased structural energy efficiency. Additionally, through the California Climate Action Registry (CCAR now called the Climate Action Reserve), general and industry - specific protocols for assessing and reporting GHG emissions have been Bell Ave. Tusibi AQ,'GHG developed. GHG sources are categorized into direct sources (i.e. company owned) and indirect sources (i.e. not company owned). Direct sources include combustion emissions from on-and off-road mobile sources, and fugitive emissions. Indirect sources include off -site electricity generation and non-company owned mobile sources. Greenhouse Gas Emissions Significance Thresholds In response to the requirements of S1397, the State Resources Agency developed guidelines for the treatment of GHG emissions under CEQA. These new guidelines became state laws as part of Title 14 of the California Code of Regulations in March, 2010. The CEQA Appendix G guidelines were modified to include GHG as a required analysis element. A project would have a potentially significant impact if it: • Generates GHG emissions, directly or indirectly, that may have a significant impact on the environment, or, • Conflicts with an applicable plan, policy or regulation adopted to reduce GHG emissions. Section 15064.4 of the Code specifies how significance of GHG emissions is to be evaluated. The process is broken down into quantification of project-related GHG emissions, making a Z7 determination of significance, and specification of any appropriate mitigation if impacts are found to be potentially significant. At each of these steps, the new GHG guidelines afford the lead agency with substantial flexibility. MIND -awn g Emissions identification may be quantitative, qualitative or based on performance standards. NE CEQA guidelines allow the lead agency to "select the model or methodology it considers most appropriate." The most common practice for transportation/combustion GHG emissions quantification is to use a computer model such as CalEEMod, as was used in the ensuing analysis. The significance of those emissions then must be evaluated; the selection of a threshold of significance must take into consideration what level of GHG emissions would be cumulatively considerable. The guidelines are clear that they do not support a zero net emissions threshold. If the lead agency does not have sufficient expertise in evaluating GHG impacts, it may rely on thresholds adopted by an agency with greater expertise. On December 5, 2008 the SCAQMD Governing Board adopted an Interim quantitative GHG Significance Threshold for industrial projects where the SCAQMD is the lead agency (e.g., stationary source permit projects, rules, plans, etc.) of 10,000 Metric Tons (MT) CO2 equivalent/year. The threshold applies primarily to industrial facilities. No threshold for residential or commercial development has been promulgated. In the absence of any adopted thresholds for roadway and commercial facilities projects, this 10,000 MT/year recommendation has been used as a guideline for this analysis. Bell A,e. Tustin AQ,'GHG - 24 - Construction Activity GHG Emissions In the unlikely event that the entire project were build out at once, CalEENIod predicts that the construction activities will generate the CO2(e) emissions identified in Table 12. Because the SCAQMD GHG emissions policy from construction activities is to amortize emissions over a 30-year lifetime, the amortized annual total is also presented. Table 12 Construction Emissions (Metric Tons CO2(e)) (194,109 sf) Year Metric Tons CO2(e) 2014 (Roadway Construction) 128.8 2018 (Facilities Construction) 522.0 2019 (Facilities Construction) 16.1 Total Construction 666.9 30 Year Annual Amortized Rate 22.2 *CalEEMod Output provided in appendix GHG impacts from construction are considered less-than-significant. Project Operational GHG Emissions The input assumptions for operational GHG emissions calculations, and the GHG conversion from consumption to annual regional CO,?(e) emissions are summarized in the CalEENIod output files found in the appendix of this report. Table 10 provides operational emissions estimates associated with planned 2-year college and commercial uses totaling 194,109 square feet of new development with an associated 10,000 daily VNIT. GHG emissions associated with the proposed project are less than the adopted 10,000 CO,(e) threshold. Project operational GHG emissions impacts are, therefore, considered to be Less- than - significant.

There are, however, already a number of programs in place that will substantially reduce the GHG emissions associated with transportation and energy consumption as the major contributors to operational GHG emissions. These programs include: • Vehicle Efficiency (Pavley, Assembly Bill 1493) • Low Carbon Fuel Standard • Tire Pressure Indicators • Low Rolling Resistance Tires • Low Friction Oils • Goods Movement Efficiency • Aerodynamic Efficiency • Medium/Heavy Duty Hybrids • Sustainable Community Initiatives (SB-375) • 33% Renewables by 2020 • Lighting Efficiency • Electrical Energy Efficiency o Natural Gas Energy Efficiency • Increased Combined Heat & Power • Industrial Efficiency • 33% Renewables by 2020 for Pumping Plants Bell Ave. I ustm AQGHG .I6. Conservatively, existing mandatory programs will reduce statewide GHG emissions by at least i 20 percent independent of any local initiatives for GHG reduction. For the proposed project, i application of projected GHG "savings" from established programs to the project GHG burden produces the following emissions residual (MT /year). Table 16 GHG Reductions through Statewide Programs (R16.419 cf_ It) Wit) Mail, triad Source BAU Reduction's Residual Energy Utilization 4,055.1 30.2% 2,830.5 Transportation 6,241.8 18.5% 5,087.1 Solid Waste 483.1 0.0% 483.1 Water Use 392.1 19.0% 317.6 Construction 55.1 0.0% 55.1 Total 11,227.2 21.8% 8,773.4 *from in -place programs by 2020 Reduction calculations from Riverside County Climate Action Plan, Section 5. 1, "Reductions from Statewide Measures," Table 5.1 "Statewide Measures and Associated Emissions from the 2020 Inventory." Whereas the project GHG impact under the BAU assumption would exceed the SCAQMD advisory significance threshold in terms of the annual emissions burden, sufficient mandatory measures are in place to reduce the total GHG emissions below the 10,000 CO2(e) threshold.

Prepared by: Giroux & Associates 1820 E Garry St., 9211 Santa Ana, CA 92705 Prepared for: RGP Planning & Development Services Attn: Jeremy Krout 8921 Research Drive Irvine, Calif. 92618 Date: March 29, 2013 Proj ect No.: P 13 -013 N MITI-, NOISE SETTING Sound is mechanical energy transmitted by pressure waves in a compressible medium such as air. Noise is generally considered to be unwanted sound. Sound is characterized by various parameters that describe the rate of oscillation of sound waves, the distance between successive troughs or crests, the speed of propagation, and the pressure level or energy content of a given sound. In particular, the sound pressure level has become the most common descriptor used to characterize the loudness of an ambient sound level. The decibel (M) scale is used to quantify sound pressure levels. Although decibels are most commonly associated with sound, "dB" is a generic descriptor that is equal to ten times the logarithmic ratio of any physical parameter versus some reference quantity. For sound, the reference level is the faintest sound detectable by a young person with good auditory acuity. Since the human ear is not equally sensitive to all sound frequencies within the entire auditory spectrum, human response is factored into sound descriptions by weighting sounds within the range of maximum human sensitivity more heavily in a process called "A-weighting," written as dB(A). Any further reference in this discussion to decibels written as "d13" should be understood to be A-weighted. Time variations in noise exposure are typically expressed in terms of a steady-state energy level equal to the energy content of the time varying period (called Leq), or alternately, as a statistical description of the sound pressure level that is exceeded over some fraction of a given observation period. Finally, because community receptors are more sensitive to unwanted noise intrusion during the evening and at night, state law requires that, for planning purposes, an artificial dB increment be added to quiet time noise levels in a 24-hour noise descriptor called the Community Noise Equivalent Level (CNEL). CNEL-based standards are generally applied to transportation - related sources because local jurisdictions are pre-empted from exercising direct noise control over vehicles on public streets, aircraft, trains, etc. The City of Tustin therefore regulates the traffic noise exposure of the receiving property through land use controls. Noise/land use compatibility standards for various classes of land uses are generally expressed in the Noise Element of the General Plan to insure that noise exposure is considered in any development decisions. The City of Tustin has guidelines for noise exposure standards which are shown in Table 1. For the most sensitive residential use, the City recommends an exterior noise exposure of 65 dB CNEL for usable outdoor space and an interior CNEL of 45 d13. For various land uses that are not occupied for 24 hours, the Noise Element of the General Plan contains standards based upon a 12-hour equivalent sound level expressed as Leq(,,).

In order to determine ambient noise levels in the project area short-term noise measurements were conducted on Wednesday, March 27, 2013 in the mid-afternoon (2:30-3:30 p.m.). These measurements serve as a baseline in determining the impact of the project acting upon area. Meter I was located on Lansdowne Rd, south of Valencia Ave., in the satellite ATEP parking lot across from the Orange County Rescue Mission play yard. Meter 2 was along Red Hill Avenue at the Bell Road intersection. The locations are shown in Figure I and monitoring results are summarized below: Measured Noise Levels (dBA) Site No. Leq Lmax Lmin LIO L33 L50 L90 1 55.4 73.0 46,5 58.0 53.0 51.0 48,0 1 2 1 679 80.0 52.0 71.5 67.5 65.5 59.0 Monitoring experience shows CNELs to be 2-3 dB higher than mid afternoon Leqs which would equate to a CNEL along Valencia of 57-58 dB and 70-71 dB along Red Hill. Land uses along Red Hill are predominately commercial. The Orange County Rescue Mission, located on Hope Drive and backing up to Lansdown has a residential component. Existing CNELs of 55-56 dB adjacent to the Rescue Mission are well within the City's residential noise standard of 65 dB CNEL. Since a doubling of traffic volumes would create a +3 dB noise increase in the logarithmic decibel scale if traffic were uniformly distributed, it would take a very large traffic increase (300%) to create a noise level that would reach 65 dB CNEL along Valencia.

The definition of a "substantial" noise impact is not defined in any guidelines. In most environmental analyses, "substantial" is taken to mean a level that is clearly perceptible to humans. In practice, this is at least a +3 dB increase. Most people cannot distinguish a change in the noise environment that differs by less than 3 dB. Some agencies, such as Caltrans, require substantial increases to be +5 dB or more. For this analysis, the more conservative traffic noise increase of more than +3 dB would be considered significant. PROJECT-RELATED VEHICULAR NOISE IMPACTS Long-term noise concerns from project development center primarily on mobile source emissions on project area roadways. These concerns were addressed using the California specific vehicle noise curves (CALVENO) in the federal roadway noise model (the FHWA Highway Traffic Noise Prediction Model, FHWA-RD-77-108). The model calculates the Leq noise level for a particular reference set of input conditions, and then makes a series of adjustments for site-specific traffic volumes, distances, roadway speeds, or noise barriers. The typical Orange County day-night travel percentages and auto-truck vehicle mixes is then applied to convert one-hour Leq levels to a weighted 24-hour CNEL. The impact of an additional 10,000 daily trips resulting from the Bell Avenue extension was evaluated using traffic volume data provided in the ATEP traffic report prepared by Stantec in March 2013. The report provides both "no project" and "with project" traffic volumes for project build-out in 2035. Table 2 summarizes the calculated 24-hour CNEL level at 50 feet from the roadway centerline along area roadway segments surrounding the project. As shown in Table 2, many roadways are expected to experience a decrease in traffic noise when the Bell Avenue extension is complete due to a shifting in traffic patterns resulting from the diverted traffic. Both Valencia Avenue and Warner Avenue are anticipated to experience up to a 2dI3 reduction in traffic noise levels. Traffic noise along Armstrong Avenue south of Valencia Ave. could experience a noise increase of +2 dB CNEL at 50 feet from the roadway centerline, but this is less than the level of human detection and less than the significance threshold. Additionally, the "with project" future traffic noise level is still less than 65dB CNEL, the noise compatibility threshold adopted by the City of Tustin for exterior residential use. The next highest project associated traffic noise increase is on Red Hill Avenue between Bell Avenue and Valencia Avenue. This +1.0 dB CNEL increase is similarly less than significance thresholds and would not create a detectable noise increase. Traffic noise associated with the addition of 10,000 trips is not expected to create a significant noise impact, ATEP Bell Ave Noise 6 Table 2 Traffic Noise Impact Analysis (CNEL in dB at 50 feet from Centerline) Road Segment 2035 No Project 2035 + Project Project Impact Red Hill Avenue/ S of Warner 70.1 70.2 0.1 S of Bell 69.5 69.9 0.4 Bell - Valencia 70.4 71.4 1.0 N of Valencia 69.5 70.2 0.7 Valencia/ E of Red Hill 67.5 65.6 -1.9 W of Armstrong 66.9 64.7 -2.2 Armstrong/ S of Valencia 62.2 64.2 2.0 N of Warner 62.2 62.2 0.0 Warner/ W of Red Hill 70.5 70.2 -0.3 E of Red Hill 702 69.0 -1.2 W of Armstrong 69.8 68.6 -1.2 E of Armstrong 69.3 68.4 -0.9 ATEP Bell Ave Noise EM KIM 111111----, .01 LIN Agreement for Exchange of Real Property Addendum/Environmental Checklist Appendices Appendix D 2012 Annual Mitigation Monitoring and Status Report, WAS Tustin FEIS/EIR April 2013 2012 Annual Mitigation Monitoring and Status Report IM Final Joint Environmental Impact Statement /Environmental Impact Report (As modified by Final Supplement #1 and Addendum to FEIS/EIR) MINE, For the Disposal and Reuse of MCAS Tustin City of Tustin Community Development Department 300 Centennial Way Tustin, CA 92780 Activities that took place in 2012 and/or are currently in progress are identified in Italic.

Background: 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. The FEIS/EIR evaluated the environmental impacts of the reuse and disposal of MCAS-Tustin, which included the adoption of a Specific Plan and other implementing actions. On December 6, 2004, the City of Tustin adopted Resolution No. 04-76 certifying a Supplement (Final Supplement 41) and Resolution No. 04-77 adopting the revised Mitigation Monitoring Report Program to the FEIS/EIR. On April 3, 2006, the City Council adopted Resolution No. 06-43 approving an Addendum to the FEIS/EIR for the Disposal and Reuse of MCAS Tustin. Included in Resolution Nos. 00-90, 04-77, and 06-43 was a requirement for a Mitigation Monitoring and Reporting Program (MMRP) for the Disposal and Reuse of MCAS Tustin. The purpose of the MMRP is to report accomplishment of mitigation measures required by the FEIS/EIR. Mitigation measures and implementation measures identified in the FEIS/EIR, Final Supplement 41, and Addendum for the disposal and reuse of MCAS Tustin have been incorporated into a table. Each mitigation measure and implementation measure is listed separately on the table with appropriate space for monitoring the progress of the implementation of each measure. Implementation measures were also required where environmental impacts were less than significant, but supported the proposed development within the reuse plan area concurrent with demand. Implementation measures and mitigation measures are both discussed in this MMRP, and are equally enforceable. The following information is identified in the table: • The measures listed by environmental impact area in the same order as they are listed in the Final EIS/EIR, Final Supplement 41, and Addendum; • The timing of implementation of the mitigation or implementation measure-, • The agency responsible for compliance; • The appropriate agency to enforce the mitigation measure or implementation measure; and • Status of the mitigation or implementation measure. The mitigation measures and implementation measures in the table are listed by environmental impact area in the same order as they are listed in the Final EIS/EIR, Final Supplement 41, and Addendum.

WAS Tustin Specific Plan Pace 3 2012 Annual Report MMRP • Master Development Site: The City and the former Master Developer, Tustin Legacy Community Partners, LLC (TLCP), entered into a Disposition and Development Agreement (DDA) in April 2006 which was subsequently amended in March 2007 and in June 2007. The DDA identified the terms of development of an approximate 820 acre footprint at Tustin Legacy and the City's sale of the property to TLCP, which resulted in conveyance of the first of four phases of property from the City to TLCP in 2007; however, TLCP defaulted on its obligations per the DDA, and the DDA was terminated on July 6, 2010. As a consequence, title to the Phase 1 property was transferred back to the City on August 5, 2010. Prior to termination of the DDA, TLCP completed a majority of the site preparation activities, including building and runway removals, and a large amount of the mass grading activities. The City subsequently completed an updated development plan: the "Tustin Legacy Disposition Strategy for the Former Master Developer Footprint" as confirmed by the City Council on April 25, 2011. The Disposition strategy provides a framework for moving forward with completing the Tustin Legacy> project pursuant to the Specific Plan with the city assuming a more limited Master Developer role by marketing smaller segment "Disposition Packages "(DPs) or parcel groupings based on market and infrastructure needs. Ten Disposition Packages (IA, IB, IC and 2 through 8) were originally created with the City reserving the ability to consolidate or otherwise refine over time as market needs evolve. E In 2012 the Cily executed Disposition and Development Agreements for the first two Disposition ONTO VIE Parcels IA -North and 2A with St. Anton Partners and the Irvine Company, respectively. Grading activities for both sites are anticipated to commence by summer 2013 resulting in the construction of 225 apartments on M -North and 533 apartments on 2A. The Irvine Company will also be responsible for constructing certain backbone infrastructure improvements, including the balance of Barranca Parkway from Tustin Ranch Road to west of Aston Street, and portions of Warner Avenue and Park Avenue west of Tustin Ranch Road The City Council has entered into an Exclusive Agreement to Negotiate with Standard Pacific on Disposition Parcels IB and 6A for the development of approximately 375 homes. The City Council also approved an Exclusive Agreement to Negotiate with the Regency for a commercial development at site IC located at the southeast corner of Kensington and Edinger Avenue. The timefraine for the disposition of the remaining Disposition Parcels is currently unknown as the City continues discussions with potential developers on various areas of the Master Development Footprint. Infrastructure Activities Major Backbone Infrastructure includes roads and may also include street lighting, traffic control, dry and wet utilities, and other work required in accordance with Governmental Requirements and EIR /EIS requirements.
