Mandeville’s lakefront is one of the most desirable places to live on the north shore, and one of the most exposed. When a storm pushes water out of the Gulf and into Lake Pontchartrain, the lake can rise over the seawall and into the streets of Old Mandeville. Homes farther from the lake can still take water when heavy rain overwhelms drainage.
Raising historic and older homes
Old Mandeville has many older raised cottages and pier-and-beam homes, which are good candidates for pier and beam house raising. Lifting them higher and setting them on new piers can protect the house while keeping its character. Homes in historic areas may face design review, so ask early about any local requirements for stairs, porches and foundation appearance.
Newer slab homes
Subdivisions built on slabs can be raised too. See slab house raising for how it works and what affects the cost.
Grants and insurance
Mandeville homeowners with prior flood claims may qualify for FEMA mitigation funding. Read our FEMA elevation grants guide and contact the city or parish to ask about open applications.
