Land Survey Costs in Harrison County, MS (2026)
Harrison County is Mississippi's Gulf Coast county, anchored by Gulfport and Biloxi. The county's economy is built on tourism, gaming, military (Keesler Air Force Base), and the maritime industries of the port. That coastal character also shapes the survey market: flood zones are extensive, elevation certificates are a constant need, and the post-Katrina rebuild has kept surveyors busy for years.
In 2026, residential boundary surveys in Harrison County range from $550 to $1,200, with standard inland lots at the lower end and coastal, bayou-adjacent, and flood-zone properties running significantly higher.
Survey Costs by Property Type
- Standard residential lot in Gulfport or Biloxi: $550 to $800
- Bayou-adjacent or flood zone residential lot: $700 to $1,000
- Near-coastal or beachfront property: $900 to $1,400+
- Elevation certificate in FEMA flood zone: $400 to $750
What Drives Costs in Harrison County
Extensive FEMA Flood Zones
Harrison County has some of the most extensive FEMA flood zone designations in Mississippi. The Gulf Coast's low elevation, bayou drainage systems, and exposure to hurricane storm surge have resulted in Zone AE and Zone VE (coastal high hazard) designations across large portions of the county. Properties in these zones require elevation certificates for flood insurance, and the elevated flood insurance premiums in coastal zones make accurate elevation documentation financially significant for property owners.
Post-Katrina Landscape
Hurricane Katrina in 2005 reshaped the Harrison County survey market. Extensive rebuilding, updated FEMA flood maps, and new construction standards for coastal properties created sustained demand for surveys, elevation certificates, and flood zone research. That demand has moderated but coastal Harrison County remains an active survey market with flood zone complexity that adds cost for affected properties.
Bayou Drainage Systems
Multiple bayou systems drain through Harrison County to the Gulf, creating flood zone corridors that extend well inland from the coast. Properties along Biloxi Bay, Back Bay of Biloxi, and the bayou systems in the northern portions of the county can be affected by flood zone designations far from the beachfront.
