City of Boca Raton Stormwater Management Master PlanPart I – Task 3 ReportNE 5th Avenue Stormwater Management ImprovementsReported Problem(s): The intersection of NE 5th Avenue and NE 23rd Way experiences repeatedflooding.System Description: There is no stormwater management system in the area. It appears that swales wereoriginally intended to accommodate stormwater runoff. However, in many locations along NE 5 thAvenue, the swale areas have been paved, presumably to facilitate parking. It appears that theintersection is a low spot in the area.Conceptual Solution(s): The recommended conceptual project for this area is the installation of inlets andexfiltration trench. The inlets will be located at the intersection, while the exfiltration trench will beplaced in the grass areas along the north and south side of NE 23 rd Way.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 43MOCK•ROOS
