requirement of 3,SU0 gpm ur ycater. The additional analysis may be as simple as calcuia:ions completed by the Public 1Vorks Department prior ro a pre-application meeting on a specific development proposal. The additional analysis must determine how the proposal's water demand will affect the entire water supply and distribution system. Projects with no additional mnjor improvements needed and no adverse cumulative impa.ts on the water supply anddistribution system are covered by this analysis, The 2.7 gpm/acre is an overall average peak hour demand assumed for planning in large areas such as the study area. However,there will undoubtedly be site-specific proposals�'rith larger demand. For example, iarge irrigation systerns can exceed 50 gpm/acre demand. Other land uses with demands much lower than 2.7 gpm/acre,such as warehouses,are assumed to occur to ofCset Ihe higher demand land uses, resulting in an overall area u ide averaee of 7..7 gpm/acre. The impacts of construction of the new water line to service development west of Japanese Gulch were not covered in the EIS. Additional SEPA analysis is rcquired to revie�a alternative routes for the line which will m;nimize the impacts of the proposal. 8.G.3 Clitig:rtion Mr�sures I.
