City of Boca Raton Stormwater Management Master PlanPart I – Task 3 ReportOld Floresta Area Stormwater Management ImprovementsReported Problem(s): The complaints on Aurelia Street (a/k/a NW 5th Street) and Hibiscus Street havebeen many since 1994. Severe ponding was also noted at the east end of these two streets during aFebruary 2008 rainfall event.System Description: There is no drainage system in this area. It appears that the original intent was forswales to accommodate the stormwater runoff. The City’s right-of-way along these two streets hasalmost entirely been encroached upon by the adjacent homeowners with extensive amounts oflandscaping.Conceptual Solution(s): It is recognized that reclamation and restoration of the intended swales alongthese two streets would significantly alter the character of the streets and neighborhood. Furthermore,Aurelia and Hibiscus Streets, as well as NW 8 th and 9 th Avenues have existing utilities beneath them thatseverely restrict the addition of any additional utility lines, such as for stormwater collection. Given theselimitations, the recommended conceptual improvement for this area is the consideration of a perviouspavement system for Aurelia and Hibiscus Streets, as well as the right-of-way along NW 8 th Avenue,between Periwinkle and Oleander Streets. Pervious pavement technology has been used successfully formany years and is gaining popularity in Florida as a stormwater management tool.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 13MOCK•ROOS
