FISCAL IMPACT None. BACKGROUND/REASON FOR RECOMMENDATIONS On October 27, the Tri Valley Transportation Council (TVTC) referred to the Contra Costa Board of Supervisors, a request by Supervisor Bishop to determine if the Tassajara Valley Property Owners Association General Plan Amendment (TVPOA GPA) application should be included in the development of the Tri Valley Transportation Plan/Action Plan (Action Plan) . When preparation of the Action Plan began in 1991, the Contra Costa Transportation Authority (Authority) required all Action Plans to begin their analysis using "Baseline" land use assumptions based on ABAG Projections 90 forecasts for 2010. This requirement established a uniform set of travel forecasts for all Action Plans and fulfilled MTC's requirements for certification of the Authority's transportation models.

Orig: Community Development Department ATTESTED OL4 Contact Person: Steven Goetz, 646-2134 PHIL BATCHELOR, CLERK OF cc: TVTC (via CDD) THE BOARD OF SUPERVISORS County Counsel AND COUNTY ADMINISTRATOR Public Works TVPOA (via CDD) BY , D UT Consider TVPOA GPA in the Tri Valley Transportation Plan/Action Plan November 8, 1993 Page Two Following preparation of the Baseline forecasts, the TVTC determined that ABAG Projections 92 forecasts for 2010 more closely reflected local planning activities of some jurisdictions. In January 1993, the TVTC directed preparation of revised land use assumptions referred to as the "Expected" scenario that allowed consideration of assumptions that varied from ABAG Projections 90 forecasts. The only direction for preparing the Expected scenario was to make every effort to keep the land use assumptions within the ABAG forecasts for 2010. C:E_�-xh- -9t_—_-A-:tdescribes the 1990, Baseline 2010, and Expected 2010 land use assumptions used in development of the Action Plan. In the Baseline scenario, ABAG's forecast for the undeveloped portion of Contra Costa was allocated by the TVTC consultant to the Dougherty and Tassajara Valleys in a speculative manner since it preceded adoption of any General Plan policy for development in this area. In the Expected scenario, County staff revised the land use assumptions according to the Dougherty Valley Specific Plan, which was adopted in December 1992 and was largely consistent with ABAG Projections 90 forecast for the undeveloped portion of Contra Costa. Exhibit A shows some deviation between the Expected and ABAG forecasts although all jurisdictions made some effort to match the ABAG forecasts. Exhibit A also includes a "TVPOA Adjusted 2010" column that adds the growth proposed in the TVPOA GPA application under review by the Community Development Department. At their October 27 meeting, the TVTC gave the Board the option of adding the growth proposed in the TVPOA GPA application to the Expected scenario even though it further exceeds the ABAG forecasts for growth likely to occur by 2010. If the Board chooses not to include the TVPOA GPA in the Expected scenario, the TVTC will attempt to develop the Action Plan to accommodate approximately 11, 000 dwelling units and 5, 372 jobs in the undeveloped portion of Contra Costa. TVTC preliminary forecasts for the Expected scenario indicate that additional transportation capacity beyond that shown in local General Plans will be needed to accommodate this level of development at the proposed Level of Service (LOS) standards. If the TVPOA application is approved as proposed by the applicant, development by 2010 in the Dougherty and Tassajara Valleys certainly could not exceed the growth shown in the Expected scenario without increasing transportation capacity or reducing LOS standards from that described in the Expected scenario. If the Board chooses to include the TVPOA GPA in the Expected scenario, the TVTC will attempt to develop the Action Plan to accommodate approximately 17 , 200 dwelling units and 6,700 jobs in the undeveloped portion of Contra Costa. Growth of this magnitude by 2010 would, at .a minimum, require examination of the extension of Hacienda Drive through Camp Parks into Contra Costa County. Past efforts by local agencies to obtain permission from the Federal government for a future extension of Hacienda Drive through Camp Parks have not been successful. The Board should be aware that the TVPOA GPA Draft EIR will evaluate the transportation impacts of a future scenario that assumes the ABAG forecasts for 2010, allocated between the Dougherty and Tassajara Valleys. The Draft EIR will also evaluate buildout of the Dougherty Valley Specific Plan and the TVPOA proposal for a horizon year beyond 2010. These scenarios are required by the Authority's technical procedures for traffic studies. The Board should be aware that the Measure C-1988 Growth Management Program and the County' s General Plan impose the following requirement if the Board chooses to approve some level of growth in the Tassajara Valley after adoption of the Tri Valley Transportation Plan/Action Plan: - The Board must find that approval of growth in the Tassajara Valley is consistent with the Action Plan. If the required studies show that this growth is inconsistent with the Action Plan, the Board must obtain the Authority's approval of a revised Action Plan that accommodates this growth before any development can proceed. The TVPOA Final EIR and related general plan studies would provide the recommendations for the required Action Plan revisions. rt I I rt >t * I H 07t4 '! m OHp �+ tnp t�f 1 �I • >` I Co K rt 0 w I--, IV -� a s � I 0 H r �► I b w � t1 4 m m 9 :7moa � � 1 I too 0 I 47 mct10a rtWMmtQ10 < I I C 1-1 • > totvDo 1 C h ? r� m m0 A. 0 Oro W - t CA H 9 C� a m i b a 0 a 0 ""m 1 a 1•+ 1 � tit x � mram 1 n r > t" 05a 00 4 War 1 :r r G7MMG I O 1-4 rwhrt OKctr010 1 > " a 0 1 �• 10 a < 00 5at< 21 . 1 W Pa F+rt m 1 m '< 0 m 0 rt 0 1 to K 010 m 1 a 1011Q�� n CC 1 v. 12 Nt 1 Fes+• O DQ. o F~+- a Fa-.
