FEMA Flood Zone Lookup

FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Cecil County, MD.

Summary

Construction within a mapped flood hazard area in unincorporated Cecil County must comply with the Floodplain District of the separate Cecil County Zoning Ordinance, adopted by the County Council on May 4, 2015. Section 157-2 of the Building Code amendments channels the IBC and IRC's flood provisions to that Zoning Ordinance rather than to a standalone building-code flood rule.

These county ordinances apply to unincorporated areas of Cecil County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Within flood hazard areas as established by Article XI, Part III, Floodplain District, of the Cecil County Zoning Ordinance as amended and adopted by the County Council of Cecil County May 4, 2015, or any construction occurring within the incorporated boundaries of the eight municipalities within Cecil County shall comply with the Floodplain Regulations as adopted by the County or floodplain regulation as adopted by such municipalities.

Full Breakdown

Cecil County's Building Code, Chapter 157, adopts the 2021 International Building Code and International Residential Code but rewrites their flood-hazard sections to point at the county's separate Zoning Ordinance instead of standing alone. 1, General, so that construction within flood hazard areas must follow Article XI, Part III, Floodplain District, of the Cecil County Zoning Ordinance as amended and adopted by the County Council on May 4, 2015, or, for construction inside any of the eight incorporated towns, the floodplain regulations that town has separately adopted.

3, Establishment of flood hazard areas, by inserting Cecil County and the same May 4, 2015 adoption date. The IRC amendment at § 157-2B(23) carries the identical rule forward for one- and two-family construction: buildings in flood hazard areas established by Article XI, Part III of the Zoning Ordinance, or by the statutes of the municipality where the project sits, must comply with the regulations of that section and any additional municipal ordinances. 1, making the Zoning Administrator, not the building permit office, the official who determines flood hazard status.

Because this file is the general and building code, not the Zoning Ordinance itself, a property owner in unincorporated Cecil County must consult the separate Zoning Ordinance's Floodplain District for the actual mapped boundaries and construction standards; Chapter 157 only establishes that those standards, not a countywide building-code default, govern.

Violations & Fines

Building in a flood hazard area without meeting the Floodplain District standards adopted May 4, 2015 is enforced the same as any other Chapter 157 violation: the Zoning Administrator or Code Official can withhold, suspend or revoke the permit under § 157-7, and violators face the civil penalties and stop-work process of § 157-9, including fines up to $1,000 or 90 days' imprisonment.

Frequently Asked Questions

Where are Cecil County's flood zone construction rules?

They sit in the separate Cecil County Zoning Ordinance, Article XI, Part III, Floodplain District, adopted May 4, 2015. Section 157-2A(14) of the Building Code amendments directs all flood-hazard-area construction to that Zoning Ordinance rather than a standalone building code rule.

Who decides if my property is in a flood hazard area?

The Zoning Administrator, or the applicable municipality's zoning authority for property inside an incorporated town, makes that determination under §§ 1612.3.1 and 1612.5 as amended by § 157-2A(16) and (17) of the Cecil County Code.

Do the county's floodplain rules apply inside towns like Elkton or North East?

No. Section 157-2A(14) applies the county Zoning Ordinance's Floodplain District only outside the eight incorporated towns; construction inside a town follows that town's own separately adopted floodplain regulations instead.
