Katy's flood damage prevention article requires anchoring, flood-resistant construction, and floodplain administrator approval for all new construction and substantial improvements in special and moderate flood hazard areas.
Katy's flood damage prevention ordinance was adopted under Texas Water Code Section 16.315 to participate in the National Flood Insurance Program. In all special and moderate flood hazard areas, new construction and substantial improvements must be designed and adequately anchored to prevent flotation, collapse, or lateral movement, using methods, practices, and materials resistant to flood damage. The ordinance restricts uses dangerous in floods, controls alteration of floodplains, stream channels, and natural protective barriers, and prevents flood barriers that unnaturally divert floodwaters. Subdivision proposals (including manufactured home parks) must provide adequate drainage and flood-resistant utility placement. The city building inspector serves as the floodplain administrator, implementing 44 CFR NFIP regulations.
Building or substantially improving structures in flood hazard areas without floodplain administrator approval, filling floodplains, or installing utilities without flood-resistant design results in stop-work orders and removal.
