Johnstown council approves Larimer County flood map update on first reading
The ordinance replaces the study reference in town code and removes a rule for measuring a structure’s lowest floor at a crawl space. The ban on crawl spaces in Special Flood Hazard Areas remains; the ordinance takes effect after final passage.
The Johnstown Town Council approved on first reading an ordinance adopting FEMA's updated flood insurance study and flood maps for Larimer County, effective Nov. 27, and removing a crawl-space measuring provision from the town's floodplain code.
A Planning Department staff member told the council that Colorado's floodplain management coordinator contacted Larimer County floodplain administrators after the Federal Emergency Management Agency issued its final determination. The town's code must reference the most recently approved flood map to comply with the National Flood Insurance Program, the staff member said.
The ordinance's recitals say state and federal regulations require the town to include certain floodplain provisions in its ordinances as part of its participation in that program.
The ordinance removes the provision for measuring a structure's lowest floor at the floor of a crawl space. It keeps the prohibition on crawl spaces in Special Flood Hazard Areas.
It replaces the Larimer County study reference dated Jan. 15, 2021, with the study effective Nov. 27, and adopts that study, its flood insurance rate maps and any revisions by reference. The Weld County flood insurance study dated Jan. 20, 2016, stays in the code.
The state and a regional FEMA representative proposed the amendments after reviewing the town's code, the staff member said, and the town attorney reviewed them to protect the code's integrity. The staff member said the changes keep the code compliant with federal and state floodplain regulations and promote public health, safety and general welfare. Of the background, the staff member said: "There's a whole lot of acronyms there I skipped, just for everyone's edification."
The Planning and Zoning Commission recommended approval at its Oct. 28 meeting. The staff member also recommended that the council approve the ordinance.
The ordinance takes effect upon final passage as provided by the Town Charter. After final reading, it is to be numbered, recorded, published and posted as the charter requires.
