FROM: Dylan Battles, Building Official DATE: June 17, 2025 RE: Amendments to Chapter 161 of the City's Code of Ordinances a€" Flood Damage Prevention RECOMMENDATION: Staff recommends approval of this ordinance. REASONS: The City of Sunny Isles Beach participates in the National Flood Insurance Program (NFIP) and its Community Rating System (CRS), a voluntary incentive program that recognizes and promotes community floodplain management practices that exceed the NFIP's minimum requirements. The City has achieved a CRS Class 8 rating, which allows residents who purchase NFIP flood insurance policies to receive premium discounts. In 2020, the NFIP's CRS program implemented new minimum prerequisites for communities to qualify for or maintain a Class 8 or better rating. To comply with these updated requirements and maintain the City's current CRS rating, manufactured homes installed or replaced within Special Flood Hazard Areas must now be elevated to at least one foot above the base flood elevation (BFE). This change necessitates an amendment to the City's existing floodplain management regulations. ADDITIONAL INFORMATION: While there are currently no residential manufactured homes within the City of Sunny Isles Beach, it is important to note that temporary structures commonly used in development projects, such as sales Item Number: 8.A 101 trailers and construction site offices, are often classified as manufactured buildings under FEMA guidelines. These structures, when placed within Special Flood Hazard Areas (SFHAs), pose similar flood risks and therefore must comply with the same elevation requirements. The revised ordinance will require that any new manufactured structures installed or replaced in SFHAs be elevated to at least the Base Flood Elevation (BFE) plus one foot, as mandated by the updated CRS Class S prerequisites. This requirement will apply to all new permit applications involving manufactured structures submitted after the ordinance is adopted on second reading. Existing temporary structures will not be retroactively affected but must comply with applicable standards in the event of replacement, relocation, or if substantially improved.
