Summary
Lansing requires new construction and substantial improvements inside the FEMA-mapped special flood hazard area to elevate the lowest floor, basement included, at least one foot above the base flood elevation, and it bans encroachments and new development inside the regulatory floodway outright. A special permit from the Planning Office is required for any floodplain use on a parcel of a half-acre or more, under City Codified Ordinances § 1250.06.
(a)Intent. It is the intent of this ordinance to protect human life, health, and property from flood conditions, to preserve the ability of floodplains to carry and discharge a base flood, and to significantly reduce potential hazards as a result of flood conditions within the City of Lansing... (d)Specific base flood elevation standards.(1)a.All new construction and substantial improvements of residential structures shall have the lowest floor, including basement, elevated to a minimum of one foot above the base flood level... (f)Special permit required. A special permit is required for use of the floodplain on parcels of one-half acre or more in size. Such requests shall be made in writing, to the Planning Office and shall be submitted to the Planning Office for recommendation, to the Public Service Department for its technical report and to the Building Safety Office for compliance with all applicable building codes relative to construction in a 100-year floodplain, before final action is taken by the City Council.

Full Breakdown
06 of the Zoning Ordinance defines the special flood hazard area as land with a one percent or greater annual chance of flooding, the base flood as the flood with that one percent chance (the 100-year flood), and the floodway as the channel and adjacent land that must stay clear of development to carry the base flood without raising the water surface elsewhere. sets the elevation standard: new construction and substantial improvements of residential structures must have the lowest floor, including any basement, at least one foot above the base flood elevation; non-residential structures can instead flood-proof to that same elevation with a registered engineer's or architect's certification filed with the Building Safety Office.
Subsection (e)(4) prohibits encroachments, new construction, substantial improvements, and development inside the regulatory floodway itself, with an exception only if a registered engineer and the Michigan Department of Environment, Great Lakes, and Energy certify no increase in base flood elevation. Any floodplain use on a parcel of one-half acre or larger needs a special permit under subsection (f): a written request goes to the Planning Office, which routes it to the Public Service Department for a technical review and to the Building Safety Office for a building-code compliance check before the City Council takes final action.
03 designate the Building Official as the local floodplain enforcement agency and adopt the same FEMA flood insurance study and FIRM panel numbers for Ingham County by reference into the Michigan Building and Residential Codes.
Violations & Fines
Section 1250.06(g) states the City's flood-protection standard does not guarantee against larger floods and creates no City liability for flood damage, so compliance is a floodplain-use requirement, not an insurance substitute. Building without the required elevation, the flood-proofing certification, or the half-acre special permit blocks issuance of a certificate of occupancy, and a registered engineer's certification is mandatory before the Building Safety Office will sign off on a non-elevated, flood-proofed structure.
