Project Description:
The Hillsborough River watershed management master plan study was completed in 2001 and updated in 2010. Many projects
were identified to alleviate the flooding, inhance the water quality, and protect the natural system. HBA2 is one of the projects to be
implemented.
The existing conditions model analysis predicts road overtopping at N Poel Road and N Peeples Road, north of W Knights Griffin
Road in the Holloman’s Branch tributary. The Holloman’s Branch crossing of N Poel road conveys runoff to the west from
approximately 1140 acres through double 36” CMPs. The conveyance system is inadequate to handle the large volume of runoff.
The N Peeples Road crossing flow direction is west through a 38”x58” CMPA that ultimately discharges into the Holloman’s Branch
tributary. Although the CMPA crossing is of reasonable capacity, the downstream culverts are undersized (30” or 36” CMPs) which
back up the system causing significant flows to sheet over Peeples Rd. to the drainage system to the north. These locations were
identified as problem locations in the 2002 WMP, and according to the report, residents have confirmed road overtopping at these
two locations. The existing conditions H&H model predicts flood depths of about 6 inches inundating approximately 450 ft of
roadway for roughly 25 hours and about 5 inches inundating approximately 550 ft of roadway for roughly 13 hours at N Poel Road
and N Peeples Rd., respectively. The alternative includes drainage system improvements coupled with the creation of additional
drainage system storage.
Describe your organizations efforts in developing, implementing and enforcing water conservation and flood protection
ordinances.
Water Conservation: Hillsborough County was the premier local government to criminalize the violation of water use restrictions,
and to adopt a civil citation process for the enforcement of the same in July 1993. A fulltime Water Conservation Manager assures
that the County stays abreast of conservation issues. This facilitates amendments to the County’s Water Conservation Ordinance
(HCO 91-27) as needed to quickly address changing conditions in the regulatory environment and as deemed appropriate by the
County’s administration.
Flood Protection: The principal purpose of Hillsborough County’s floodplain management program is to protect residents and
business owners from flooding risks. Flooding disasters are the leading recurring hazard within the County and have the potential of
affecting greater than one-quarter of the population at a value that is greater than five billion dollars in personal property.
