Brooklyn Park, MN Environmental Rules: Flood Elevation Requirements (2026)

801(D). 105 as an elevation no lower than two feet above the regional flood, plus any rise caused by floodway encroachments, essentially a two-foot freeboard above the 100-year flood. 801(D)(4)(b)1 requires that all structures, including accessory structures, be elevated on fill so the lowest floor sits at or above that regulatory flood protection elevation, with finished fill no lower than one foot below the regulatory elevation and extending at least 15 feet beyond the structure's outside limits. Accessory structures under 576 square feet used only for parking or storage may instead be floodproofed to FP3 or FP4 State Building Code classifications rather than filled, provided utilities are water-tight or elevated, materials resist flood damage, and the structure carries at least two automatic flood-venting openings sized to one square inch per square foot of enclosed floor area.

Fill placement on a Flood Fringe parcel is capped at 1,000 cubic yards unless it is elevating a structure or approved as a conditional use. 608 for nonresidential basement standards. 801(D)(2).
