The Southwest Florida Water Management District (District) is subdivided into hydrologic basins. On December 16, 2008, the District’s Governing Board adopted a resolution that merged the Northwest Hillsborough Basin and the Hillsborough River Basin pursuant to its authority as provided in Section 373.0693(1)(a), F.S. This action followed management studies of the District that concluded by combining the Northwest Hillsborough and the Hillsborough River Basins the District could reduce agency expenditures and eliminate unnecessary duplication of work. This rule amendment will revise the current legal description of the basin boundaries to reflect the Board’s action.
