The purpose of this page is to define subdivision, a commonly used term in floodplain management.
Definition/Description
A community must review subdivision proposals and other proposed new development including manufactured home parks or subdivisions, to determine whether such proposals will be reasonably safe from flooding.
If a subdivision proposal or other proposed new development is in a flood-prone area, any such proposals shall be reviewed to assure that: (i) All such proposals are consistent with the need to minimize flood damage within the flood-prone area; (ii) All public utilities and facilities, such as sewer, gas, electrical, and water systems are located and constructed to minimize or eliminate flood damage; and (iii) Adequate drainage is provided to reduce exposure to flood hazards.
BASE FLOOD ELEVATION (BFE) DATA REQUIREMENT: Communities must require that all new subdivision proposals and other proposed development (including proposals for manufactured home parks and subdivisions) greater than 50 lots or 5 acres, whichever is the lesser, must include within such proposals, BFE data.
