<strong>City</strong> <strong>of</strong> <strong>Boca</strong> <strong>Raton</strong> Stormwater Management <strong>Master</strong> <strong>Plan</strong>Part I – Task 3 ReportSpanish River Road Stormwater Management System ImprovementsReported Problem(s): This road has been reported numerous times over the years for ponding androadway flooding.System Description: The road is relatively flat, but does appear to be positively sloped to drain to theexisting inlets, which are piped to outfalls in the adjacent ICWW. Several “traffic calming” devices(speed humps) have been installed that prevent the flow <strong>of</strong> the stormwater run<strong>of</strong>f to the inlets. There arelow points that have presumably occurred as a result <strong>of</strong> resurfacing <strong>of</strong> the roadway.Conceptual Solution(s): The recommended conceptual improvements for this area include re-grading theroadway (by overlaying it) from Ponce de Leon Road to SE 31 st Street to achieve a center crown so thatstormwater will run<strong>of</strong>f to adjacent properties and not pond in the roadways; reconstructing the trafficcalming devices to allow run<strong>of</strong>f to flow around them; and adding inlets on the northeast and northwestcorners <strong>of</strong> Spanish River Road and Via Cabana Drive and connecting those inlets to those at the west end<strong>of</strong> Via Cabana Drive.Water Quality Impacts: Since the ponding that occurs in the roadway eventually either drains into theground or evaporates, the proposed improvements will not change water quality level for this area.L:\boca\bocaswmp\A6016.03\rp02accm.docPage 51MOCK•ROOS
