Flood Control Zone District

The Board of County Commissioners formed a Flood Control Zone District through resolution on July 17, 2012. On August 7, 2012, the BOCC approved a resolution placing a measure on the November 6, 2012 ballot to ask the county residents whether the district should be funded. Voters approved funding of the FCZD.

Floodplain development permits are required prior to beginning any work on improved or unimproved real estate within the 100-year floodplain. This includes, but is not limited to, buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials located within the areas of special flood hazard. Floodplain permits can be found on the Fees and Applications page.
