Irvine Ranch Water District San Diego Creek Watershed Natural Treatment System (NTS)
NOP - Notice of Preparation of a Draft EIR
The proposed program 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 Program includes a Master Plan which is being developed to describe the watershed-wide system for the natural treatment of low-flow and initial storm runoff generated within the San Diego Creek Watershed. The proposed NTS Program consists 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 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.
