Project 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 and by wave action has caused environmental damage to the existing seagrasses and mangroves. There are 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 causing upstream localized flooding and have very high velocities through the outfall pipes. The 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 (see attached exhibits). A baffle drop box with a sump is proposed to dissipate the energy and reduce the velocity at
the outfall thereby eliminating erosive discharge velocities and allowing for sediements to settle out within the box, which will be
removed by routine maintenance. 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 futher 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 seagrasses and mangroves along the shoreline and
will eliminate localized flooding in the upstream areas. Also, a conservation easement has been obtained to protect the seagrasses
and mangroves along the shoreline (see attached document).
This is a request to provide the second and final year funding (FY2014) for the Bayshore Drive Drainage Improvement project
(N434). The Town was previously approved for a cooperative grant in FY2010 (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 elected to revise
the design in order to reduce the overall cost to under $2M while at the same time providing improved habitat, water quality and
flood protection benefits for the area. In 2011 the project scope was modified with a final estimated total cost of $1,740,000. The
Town submitted a cooperative funding application for FY 2012 for an amount of $1,740,000 of which the Town and District would
fund equally at fifty percent each. The request was approaved and based on the project schedule and cash flow needs, a total first
year funding amount of $800,000 was approved for FY 2013. The request for $940,000 in FY 2014 represents the remaining
project costs.
