Project Description:
The City of Belleair Bluffs is a coastal municipality located in west central Pinellas County. The City experiences substantial grade
fluctuations which are somewhat unique to the County. While the City's terrain adds to the "charm" of this municipality, it can often
exacerbate stormwater collection issues that plague similar communities. A majority of the roadways do not utilize curbing or
drainage structures for stormwater collection and conveyance. Therefore, these non-curbed roadways allow for stormwater runoff
to flow down-grade, which often results in structural flooding. Further, these lengthy stormwater flow paths provide multiple
opportunities for runoff to collect floatables, sediment, oils, greases and nutrient rich material (i.e. fertilizer from landscaped areas).
Residents and City staff often view uncontrolled stormwater flow during non-extreme storm events. Drainage system
improvements, as proposed by the City, allow for stormwater to be collected and conveyed to outfalls. Doing so minimizes the
occurrences of structural flooding and reduces the stormwater path, thus limiting opportunities for stormwater to collect pollutants
resulting in water quality improvements.
In 1999, the City of Belleair Bluffs authorized a drainage evaluation of the Sunset Bluff Basin. The Sunset Bluff Basin, which is the
portion of the City west of Indian Rocks Rd., was divided into multiple sub-basins. These sub-basins were evaluated and drainage
improvements were proposed that would minimize stormwater flow paths and reduce overall flooding. Implementation of the study's
recommendations has been ongoing for the past several years.
The purpose of the City of Belleair Bluffs' Implementation of BMPs within Basin SD-2 & SD-3 project is to continue these drainage
improvements, as outlined in the aforementioned study. The "SD-2" & "SD-3" designations refer to Sunset Bluff sub-basins located
on Bluff View Drive (SD-2) and Pinehurst Drive (SD-3) in which the installation of stormwater inlets and associated piping is
proposed. Disallowing stormwater to sheet over heavily fertilized landscaped areas will minimize the amount of nutrient rich
material entering Clearwater Harbor. Please reference the attached location map to view the locations in which storm structure and
piping installation is proposed.
The City is aware that the implementation of BMP's is vital to improving water quality as it enters the stormwater system and is
eventually discharged to Clearwater Harbor. If the above improvements are constructed, the newly collected flows would be routed
towards an existing outfall. Prior to discharge, the flows must pass through an existing hydrodynamic separator (Stormceptor)
which would treat the stormwater. Devices using this technology have the ability to collect large floatables and small sediment.
Greases and oils are also removed by being captured within the devices' internal baffles. Studies have found that this technology is
