Harrison County requires grading permits for excavation or fill over 50 cubic yards. Drainage must not redirect water onto neighbors under MS riparian and civil-law drainage rules. Retaining walls over 4 feet need engineering.
Harrison County regulates grading and drainage through its planning department and engineering standards. Grading permits are typically required for excavation or fill exceeding 50 cubic yards or disturbing more than 5,000 square feet. Site plans must demonstrate that post-development drainage directs water away from adjacent properties without increasing flow onto neighbors; Mississippi follows a modified civil law rule that prohibits altering natural drainage patterns to a neighbor's detriment. Gulfport and Biloxi require drainage and grading plans for all subdivisions and most new commercial construction. Retaining walls over 4 feet (measured from bottom of footing to top of wall) require sealed structural engineering and separate permits. Coastal clay and sandy soils present compaction challenges; independent compaction testing is required for structural fill. Final grade must match approved plans before certificate of occupancy issues.
Unpermitted grading over threshold: stop-work + $250-$2,500. Redirected drainage causing neighbor flooding: civil liability + corrective order. Retaining wall over 4 ft without engineering: removal or retrofit at owner cost. Slope failure: full remediation liability.
