Document Description
The NTS plan is a watershed-wide system for the natural treatment of storm runoff and dry weather flows generated within the 122 square mile San Diego Creek Watershed and approximately 1.3 square miles of the Santiago Creek Watershed. The Santiago Creek Watershed is a tributary of the Santa Ana River. The NTS plan consists of a system of 31 constructed water quality treatment wetlands. These facilities use wetlands vegetation and take advantage of naturally occuring physical, chemical, and biological processes to treat the runoff and dry weather flows. 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.
