Project Description:
The Timber Oaks Golf Course is located in a large closed sub-basin of the Double Hammock Creek Basin. It is located east of US
19 and west of Little Road in sections 11 and 14, township 25, range 16. The golf course is approximately 70 acres in size and is
completely surrounded by high density housing. In 2003 and 2004 sever flooding occurred on and around the golf course. Many
homes were flooded and extensive pumping operations from the course into Dollar Lake, an active sink hole, prevented more
serious damage. Following the flooding, Pasco County hired an engineering firm to evaluate the area and as a result of their
analysis the basin was designated a closed basin of special concern by the Board of County Commissioners. This designation
places design requirements on the area far in excess of SWFWMD requirements. The designation helps prevent further flooding
but does nothing to reduce current flood potential. At the same time the engineering study was performed a parallel study of
potential flood reduction projects was completed. It has been determined that the golf course itself is the only remaining area not
developed in the basin. A preliminary design for a regional stormwater facility on the golf course indicated that it would provide
significant flood relief. Currently the golf course is available for development. This project for design, permitting, acquisition and
construction would create an open water lake with significant created wetlands over the entire golf course area providing flood relief
to many structures and environmental improvements by eliminating nitrogen infiltration from the golf course and creating large
areas of wetlands along the perimeter. Maximizing floodplain mitigation on the site could develop 208 acre-ft of additional floodplain
storage. This floodplain mitigation area will provide storage for 100% of the above indicated ponding volume of 96.37 acre-ft,
staging at elevation 13.00, and for approximately 50% of the volume of pumping or 111.50 acre-ft staging at elevation 15.41. The
volume of combined ponding and pumping was recorded during a major storm event of 100-year rainfall intensity. Although the
combined available ponding storage of existing and proposed floodplain storage provides 208 acre-ft at elevation 15.41, continued
pumping, in reduced and delayed volumes, would be required to protect surrounding structures. The proposed mitigation area will
provide adequate storage capacity to accomodate the flooding volume generated during rainfall events of lesser intensity and
pumping will not be necessary. The facility would be managed in perpetuity as a stormwater park with limited passive recreation.
Describe your organizations efforts in developing, implementing and enforcing water conservation and flood protection
ordinances.
Pasco County has adopted Ordinance 01-08 requiring the following: one day per week irrigation restrictions for potable water;
curtailed use of potable water for irrigation when rain has occurred within the last 24 hours; scheduled availability and restricted use
of reclaimed water for lawn and landscape irrigation to 2 days per week county-wide to serve as many customers as possible;
washing of non-business, personal vehicles only using low volume methods and over non-impervious surfaces; prohibiting
aesthetic uses of water unless such provides a necessary aeration or water quality benefit; and the use of reclaimed water for road
