Flood control lot
A flood control lot is NSW land where flood-related development controls apply, disclosed on a Section 10.7 certificate. CDC and DA rules differ on these lots.
Ask Chalkline about this →A flood control lot is a land parcel in NSW where flood-related development controls apply, as defined under the Environmental Planning and Assessment Regulation 2021. The status is disclosed on the Section 10.7 planning certificate: a certificate must state whether the land is within the flood planning area or between the flood planning area and the PMF level, and whether flood-related controls apply (verified 2026-05-09: NSW Planning Portal, Section 10.7 Service).
If a site is a flood control lot, the council DCP flood chapter sets the minimum floor level, overland flow path restrictions, fencing requirements, and any Flood Management Report obligations. Complying development (CDC) is available on flood control lots under the SEPP (Exempt and Complying Development Codes) 2008, but requires an engineer’s flood certificate confirming the proposed floor levels comply with the applicable standard. Sites in High Flood Risk Precincts or floodways typically cannot satisfy CDC criteria and require a DA instead.
