within a five-mile radius of the Project Site (in relation to migratory species). Projects within the geographic scope of analysis include a variety of proposed urban land uses as listed in Table 6-2, above, and include Cumulative Projects 1-16 and 18-22. The geographic context for analysis of cumulative impacts on biological resources also encompasses the reach of the Tuolumne River between the Hetch Hetchy Reservoir (O’Shaughnessy Dam) and Don Pedro Reservoir, with particular emphasis on the meadow and alluvial features in this reach, including the Poopenaut Valley.

Cumulative Impacts along the Tuolumne River

As discussed in Section 4.O, as part of the proposed water transfer from OID, the SFPUC would hold 2,400 AFY in Hetch Hetchy Reservoir instead of releasing it down the Tuolumne River for capture by MID/Turlock Irrigation District (TID) in New Don Pedro Reservoir and redirecting that 2,400 AFY to Brisbane through its regional water system. The SFPUC evaluated the effects of increasing diversions from the Tuolumne River and, in turn, reducing flow releases from Hetch Hetchy Reservoir on the Tuolumne River and its resources in the program EIR it prepared on its Water System Improvement Program (WSIP) (San Francisco Planning Department, 2008). This program EIR is incorporated by reference and is available for review on the San Francisco Planning Department website (http://www.sf-planning.org/index.aspx?page=1829) and also at the City of Brisbane Planning Department during regular business hours.

 

The WSIP Program EIR evaluated the impacts of a range of possible additional diversions from the Tuolumne River from 2 mgd to 24 mgd. As described and analyzed in the WSIP Program EIR (Volume 7a, page 13-8, Table 13.2, and Volume 8, Appendix O-3), the adopted WSIP would result in an increase in average annual diversions of 2 mgd from the Tuolumne River over existing conditions in the area along the Tuolumne River between Hetch Hetchy and Don Pedro Reservoirs. The WSIP Program EIR described and analyzed impacts on the following potentially affected resources (see Program EIR Volume 3, Section 5.3, and Volume 7a, Sections 14.5, 14.6, and 14.7): stream flow and reservoir water levels, geomorphology, surface water quality, surface water supplies, groundwater, fisheries, terrestrial biological resources, recreational and visual resources, and energy resources. With one exception, the WSIP Program EIR determined that impacts of the adopted WSIP—including the
