Utilities

All drainage facilities would be constructed according to Los Angeles County Department of
Public Works standards and requirements. The project site is partially within the Castaic Lake
Water Agency’s (CLWA) service area and the project site does not contain any existing potable
water infrastructure. Therefore, annexation to CLWA is required for the project site not currently
within the service area. The Newhall County Water District (NCWD), one of four retail water
purveyors within CLWA, would provide potable water to the project. Due to the elevations of the
residential lots, three reservoir tanks and one booster pump station would be constructed on the
project site on two separate graded pads. These tanks would provide a total of three million
gallons of potable water for the project site and would be adequate for all water supply and fire
suppression needs on the site.

The project site does not contain any existing sewage infrastructure. Development of the
proposed project site will require the construction of sewer pipelines. The project would need to
be annexed into Los Angeles County Sanitation District No. 32. Sewer pipelines from the
project site would connect with the existing main sewer trunk lines at Castaic Road and Tapia
Canyon Road.
