City of Boca Raton Stormwater Management Master PlanPart I – Task 3 ReportNW 36th Court Stormwater System ImprovementsReported Problem(s): The reported problems are road, yard, and driveway flooding along the southwestside of the road, particularly severe at house number 370.System Description: There is no apparent stormwater management system along NW 36 th Court betweenNW 3 rd and NW 4 th Avenues. Site observation indicates that the road cross slopes to the southwest side,and along the alignment, slopes to low point at or near house number 370. The adjacent house to thewest, has a paved swale area in the right-of-way.Conceptual Solution(s): The recommended conceptual improvement is to install inlets and exfiltrationtrench along the southwest side of the road, re-grade the grassed area on the northeast side of the road as aretention area, and connect the exfiltration trench to the retention area via a pipe under the road.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 9MOCK•ROOS
