Document Description
The City of Coronado proposes to replace an existing 24-inch storm drain outfall with a new 48-inch storm drain outfall at the same location. The new outfall will carry drainage from the existing outfall as well as drainage from a new storm drain system along "I" Avenue intended to mitigate for existing flooding problems at the Fourth Avenue/Alameda Boulevard intersection. The new storm drain will run the length of "I" Avenue from Fourth Street to the San Diego Bay and will intercept the existing 24-inch storm drain conveying flows from First Street just prior to the existing point of discharge of the 24-inch pipe. A low-flow diverter will be installed to divert low flows to the sanitary sewer system and not the storm drain outfall. The top of the existing reinforced concrete pipe is located at the mean higher high water; the proposed top of pipe will rise above the high tide line, equivalent to the annual highest high tide.
