City of Boca Raton Stormwater Management Master PlanPart I – Task 3 ReportNW 5th Avenue Stormwater System ImprovementsReported Problem(s): Ponding occurs regularly at the corner of NW 5 th Avenue and the short connectorroad considered part of NW 4 th Court.System Description: There is an inlet on the southeast corner of this intersection. This structure has apipe connection to the west; but across the street, where a second inlet would be expected, there is anewly reconstructed driveway and small landscaped island. It is presumed that an inlet in this area hasbeen filled or covered over. The ultimate outfall, if any, is unknown.Conceptual Solution(s): The recommended conceptual project is to construct a dry retention area alongthe northwest side of NW 5 th Avenue, just north of NW 35 th Street. (The City has a 100-foot right-of-wayfor NW 5 th Avenue and currently uses only about 20 feet for the existing road.) A pair of new inlets at theproblem intersection is proposed to be connected, via a bubble-up structure, to the dry retention area.Water Quality Impacts: The proposed conceptual solution is anticipated to have a positive impact onwater quality. Runoff will more readily enter the ground water system than it currently does. This resultsin less travel time over potentially contaminated ground surface.L:\boca\bocaswmp\A6016.03\rp02accm.docPage 17MOCK•ROOS
