Summary

Maple Grove restricts development inside its mapped floodway, flood fringe, and general floodplain districts to uses expressly permitted or conditionally approved, and bans critical facilities like hospitals and fire stations outright.

Within the floodplain districts established in this division, the use, size, type and location of development must comply with the terms of this division and other applicable regulations. In no case shall floodplain development adversely affect the efficiency or unduly restrict the capacity of the channels or floodways of any tributaries to the main stream, drainage ditches, or any other drainage facilities or systems. All uses not listed as permitted uses or conditional uses in sections 36-646, 36-647 and 36-648 are prohibited. In addition, critical facilities, as defined in section 36-644(h)(5), are prohibited in all floodplain districts. (Code 2003, § 36-653; Ord. No. 16-15, § 1(exh. A), 11-7-2016)

Full Breakdown

Maple Grove's floodplain overlay districts (§ 36-643 et seq.) apply on top of underlying zoning wherever the city's adopted FEMA flood insurance rate maps show floodway, flood fringe, or general floodplain area. Under § 36-645(b), any use, structure, or site work in these zones must fit a use permitted or conditionally allowed under §§ 36-646 through 36-648, and can't reduce the flow capacity of streams, channels, or drainage systems. Hospitals, correctional facilities, schools, and fire and police stations are prohibited outright in every floodplain district, regardless of underlying zoning, anywhere in Maple Grove, Hennepin County, Minnesota.

Violations & Fines

Floodplain violations are misdemeanors under § 36-654, enforced by the zoning administrator and city engineer; the city can also pursue injunctions, corrective-work orders, or seek denial of flood insurance.
