Fully verified Floodplain engineering (PE / CFM certification) Metairie, LA · Louisiana Gulf

Linfield, Hunter & Junius, Inc.

The only firm found holding both engineering and land surveying registration in Louisiana while also offering in-house architecture. That matters here because the FEMA Floodproofing Certificate may be signed by a registered engineer or a registered architect, so both signature paths sit under one roof. Registered since 1979.
