Master Plan Development - City of Boca Raton

City of Boca Raton Stormwater Management Master PlanPart I – Task 3 ReportG. Other System ImprovementsThe drainage complaint log and discussions with the City included a number of reports of isolatedponding, driveway flooding, and cul-de-sac flooding. Many of these were evaluated in the WHS report of1998. Review of the WHS report, confirmed by field observation, indicated that in some instances,property owners have simply failed to maintain the swale that serves them, or otherwise altered the swalearea or driveway in such a manner as to cause the ponding that generated the complaint. In many cul-desacareas, redevelopment has eliminated the overland flow routes that stormwater runoff once used,thereby trapping water in the streets. It is recommended that these issues be evaluated and addressed on acase-by-case basis. In order to allow for these efforts, two additional, annually recurring, capitalimprovement programs are recommended below. These recurring projects will allow the City to plan forand address new problem areas on a continuing basis.Swale Restoration ProgramBecause the swale degradation issue is widespread in location, and because experience reveals that manyswales will continue to become non-functional as a result of homeowner activities (landscaping, lack ofmaintenance, etc.), an ongoing, systematic swale restoration program is proposed as a recurringimprovement project for the City. It is further recommended that this program include an annual reviewof outstanding drainage complaints to determine which swales will be restored in the upcoming year.This planning activity should be carried out at the start of the calendar year, in order to be included as aspecific annual improvement project in the budget for the subsequent fiscal year.Cul-de-sac Rehabilitation ProgramField observation of a number of cul-de-sacs indicated that either when they were constructed, or as aresult of repaving/resurfacing, no positive drainage exists for these areas. The optimum solution for eachof these cul-de-sacs must be considered on a case-by-case basis. It is again recommended that a recurringannual budget line item be included in the stormwater utility budget. This planning activity should becarried out at the start of the calendar year, in order to be included as a specific annual improvementproject in the budget for the subsequent fiscal year.L:\boca\bocaswmp\A6016.03\rp02accm.docPage 62MOCK•ROOS
