Tampa Bay Mitigation Bank
Tampa Bay Mitigation Bank is located in the southern portion of Hillsborough County, Florida. The bank site is approximately 161 acres and provides both saltwater and freshwater mitigation credits in the Tampa Bay Basin. The TBMB site consists of 161.2 acres surrounding the headwaters of Andrews Creek, on the southeast portion of the peninsula between Little Cockroach Bay and Cockroach Bay, east of the southern portion of the Southwest Florida Water Management District's (SWFWMD) Cockroach Bay Habitat Restoration Project in southeastern Hillsborough County, Florida
Tampa Bay Mitigation Bank may be used by both private and public clients for developments, infrastructure, roadway improvements, and other projects within the coastal portions of Hillsborough, Pinellas, and Manatee Counties. Led by Birkitt Environmental Services, Inc., Tampa Bay Mitigation Bank was designed utilizing a reclaimed shell mining area located on the Cockroach Bay Peninsula in the immediate vicinity of the Hillsborough County Cockroach Bay Habitat Restoration Project.
The bank includes the creation of saltwater and freshwater wetlands on former agricultural lands. The bank will include enhancement of Andrew's Creek, which drains to Cockroach Bay Aquatic Preserve and restoration of native upland habitat surrounding the wetlands. This wetlands creation and restoration provides significant ecological and water quality benefits to Cockroach Bay and the Tampa Bay Estuary.
An important element of the TBMB is the enhancement of Andrews Creek and creation of tidal tributaries through elevational adjustment allowing tidal inundation of excavated wetland basins through Andrews Creek. Approximately 40.0 acres of low and high saltmarsh interspersed with mangroves will be established through red mangrove (Rhizophora mangle) planting and recruitment, and planting saltmarsh cordgrass (Spartina patens), saltmeadow cordgrass (Spartina alterniflora), seashore paspalum (Paspalum distichum), saltwort (Batis maritima), and glasswort (Salicornia virginica) to accelerate saltmarsh establishment (Myers and Ewel 1994).
