Recommendation
Fund as a High priority. The project provides water quality improvement by routing water through a sump and reducing stormwater
velocities thus providing erosion protection and addresses flooding along Bayview Drive.
Description
The Town of Belleair has been experiencing shoreline erosion along the Bayview Drive shoreline from Manatee Road to the bridge
north of Ocala Road (approximately 2,700 LF). The continuous erosion caused by a combination of stormwater discharge,
groundwater seepage and wave action has caused environmental damage to the existing sea grasses and mangroves. There are
(7) seven existing stormwater discharge pipes that collect runoff from a 113.27 acre tributary. The storm outfalls discharge through
the bluff side banks about midway up the slope causing severe erosion of the bluff banks and at the toe of the bluff. The existing
storm outfalls are also undersized resulting in localized upstream. The plan is to capture the runoff currently discharging through
seven storm outfalls into a single storm pipe and directing all the runoff to one outfall location. A baffle drop box with a sump is
proposed to dissipate the energy and reduce the velocity at the outfall. The segment of pipe from the baffle box to the bay will also
be lowered so the pipe invert is slightly above the bottom of the bay in order to reduce erosion. The bluff banks around the new
outfall will be stabilized with rubble rip-rap. The existing storm outfalls will then be removed, abandoned or capped eliminating
erosion and sedimentation at those locations. This improvement will provide significant benefit to the existing sea grasses and
mangroves along the shoreline and will eliminate localized flooding in the upstream areas. Also, a conservation easement has
been obtained to protect the sea grasses and mangroves along the shoreline.
Benefits
The project will significantly reduce the sediments entering Clearwater Harbor and reduce stormwater velocities thereby reducing
shoreline erosion and improving water quality in Clearwater Harbor. Additionally, the project will provide localized flooding relief to
the residential areas east of Bayview Drive.
Costs
The total project cost is estimated to be $800,000. The Town has requested $400,000 from the District in FY2013 and will provide
an equal match. The FY2013 funds will be used for design, permitting, and the first phase of construction.
Additional Information
The Town was previously approved for a cooperative grant in 2009 (Agreement No. 09C00000068) in the amount of $5M to provide
the environmental and flood protection benefits listed above. Under the original grant, the proposed improvements consisted of
stabilizing approximately 2,700 linear feet of the bluff bank. Due to the economic conditions, the Town has elected to modify the
design in order to reduce the overall cost to under $2M while at the same time providing comparable environmental and flood
protection for the local area.
