Capital Development Committee. Local government floodplain management regulations for development in floodplain areas must equal or exceed the federal emergency management agency's national flood insurance program's (national flood insurance program) minimum design and construction criteria and must comply with the Colorado water conservation board's (CWCB) rules and regulations for regulatory floodplains in Colorado. Not all local governments participate in the national flood insurance program. The bill requires the office of the state architect to develop a state floodplain management program (program) by June 30, 2025, which will ensure compliance with the minimum floodplain management criteria of the national flood insurance program and with the CWCB's rules and regulations for regulatory floodplains in Colorado. The program applies to development on state-owned land in counties and municipalities that do not participate in the national flood insurance program. At the discretion of the office of the state architect, the program may also apply to state-leased properties in counties and municipalities that do not participate in the national flood insurance program. (Note: This summary applies to the reengrossed version of this bill as introduced in the second house.)
