Proposed Changes to Chapter 8
1. Require manufactured homes to meet same elevation as other homes
— CRS Requirement
2. Clarify when certain forms are required
— CRS Requirement
3. Community Development Board hear variances/appeals
— Instead of Commission
— Similar experience with land development variances/appeals
4. Relaxed regulations for accessory structures (FEMA policy)
— New FEMA Policy
— Will not impact CRS rating
5. Don't allow stem walls when subject to wave heights 1.5' to 3' tall
— FEMA recommendation
— More prone to failure than open foundations (pier or pile)
6. Prohibit use of fill to elevate homes within floodplain
— Protect neighbors
— Stem walls, piers, etc. allowed for elevation
