Document Description
The proposed plan that will be evaluated in the Program EIR is the San Diego Creek Watershed Natural Treatment System Program (NTS Program) which has been prepared by IRWD. The NTS Plan describes a watershed-wide system for the natural treatment of low-flow and initial storm runoff generated within the San Diego Creek Watershed and a small portion of the Santiago Creek watershed. The proposed NTS Plan consists of a system of constructed water quality treatment wetlands and natural biofilters. These take advantage of naturally occurring physical, chemical, and biological resources to treat the runoff. The natural and man-made drainage features within the San Diego Creek watershed all drain via San Diego Creek and its tributaries into Upper Newport Bay. These flows then enter Lower Newport Bay on their way to the Pacific Ocean. The portions of the project area located within the Santiago Creek watershed drain primarily into Upper Peters Canyon Resrevoir and to Santiago Creek, a tributary of the Santa Ana River.
