Hillsborough County requires grading permits for any earthwork over 50 cubic yards or affecting drainage patterns. LDC §4.01 prohibits altering natural drainage to harm adjacent property. Finished grade must direct water to approved stormwater system, not neighboring lots.
Flat Tampa Bay terrain makes drainage control critical. Hillsborough Development Services requires a site plan showing existing and proposed grading, drainage patterns, and swale alignment for new construction. Altering swales, culverts, or filling wetlands without permit strictly prohibited. Finished grade must slope away from foundation at least 6 inches in first 10 feet per FBC 1804.4. Wetland impacts require SWFWMD and possibly USACE Section 404 permits. Neighbor drainage disputes common - county investigates but often refers to civil remedy.
Unpermitted fill: 500-5,000 dollars plus restoration. Altered drainage harming neighbor: civil liability plus code lien. Wetland fill without permit: FDEP and USACE enforcement.
