Riverside Drive Flood Control Channel Water Quality Improvement Project
Document Type
MND - Mitigated Negative Declaration

Document Description
The proposed project would modify the existing flood control channel to capture and infiltrate dry-weather flow to improve water quality while maintaining its ability to convey the 100-year storm event. The existing flood control channel is approx 80-ft wide at the top, 40-ft wide along the bottom, six-ft deep, and 1,238 ft long with a two-ft thick clay liner. In the center of the channel is a 1,133 ft long 3-ft wide low-flow concrete channel that is flanked by 2% slopes. Four outlets from the Paseo Palmas and Paseo Vista subdivisions discharge directly at the 3-ft wide low-flow concrete channel. The flood control channel's current design allows dry-weather flow from the neighborhood drainages to discharge downstream into the channel which is part of Eucalyptus Hill Crk and is a tributary of the San Diego River. Water quality of the dry-weather flow was analyzed in 2016; it was determined that pH, fecal coliform, Enterococcus, total nitrogen, total phosphorus, and iron exceeded the numerical action levels and entered the channel. The proposed channel improvement would capture and infiltrate dry-weather flow to improve water quality in the project area and downstream.
