MOUNTAIN HOUSE PROPOSED MACHADO TENTATIVE MAP 4.ENVIRONMENTAL CHECKLIST - 4.16 UTILITIES AND SERVICE The proposed project would include 255 low density(R/L) dwelling units, 31 medium density(R/M) dwelling units, and 29 second dwelling units(Associated Engineering, 2006). The proposed project would also include 18.1 acres of Office Commercial space, 21.5 acres of Limited Industrial Space and a 16.5 acre K-8 school site (EDAW, 2005a). The water demand and wastewater generation for the proposed project at build-out is presented in Table 4.16-1. The water demand and wastewater generation are 15.2 and 20.0 percent respectively, — of the totals for Specific Plan III.

Planned expansions of the WTP and W WTP; construction of water mains, storage tanks, _ pump stations, and water distribution pipelines; and construction of sanitary sewers would all be constructed to serve the proposed project before the residences or commercial,office and industrial buildings could be occupied. Construction of these utility improvements within the _ project site would occur prior to paving the streets and completing the houses and buildings. These utility improvements have been subjected to previous separate environmental impact assessments as required by CEQA including the SPIIIEIR. These assessments have _ identified impacts that may be potentially significant and proposed mitigation measures to reduce the impacts to less-than-significant levels. Therefore, a less-than-significant impact would occur with respect to construction and expansion of water and wastewater facilities to _ serve the proposed project. c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Planned extensions of the storm drain system would be constructed to serve the proposed project before the residences or commercial, office and industrial buildings could be occupied. Construction of the storm drains within the project site would occur prior to 4-86
