Jefferson County’s flood zones are concentrated along Bear Creek and Clear Creek, the two major drainages that run from the foothills through the county’s urban tier. Properties near these waterways may fall within FEMA-designated Special Flood Hazard Areas and need an elevation certificate for flood insurance. In 2026, elevation certificates in Jefferson County run $475 to $750 for urban properties and $550 to $900 for mountain and foothills locations.
Bear Creek Flood Zone
Bear Creek originates in the foothills near Evergreen and runs east through Morrison, Lakewood, and into Denver. The Bear Creek corridor through Lakewood has FEMA Zone AE designations affecting properties near Bear Creek Lake Park, Belmar neighborhood, and the Green Gables area. The creek passes through Bear Valley and the areas near the C-470 corridor in southwest Lakewood. Properties within the Bear Creek floodplain in Lakewood are most commonly asked for elevation certificates.
Clear Creek Flood Zone
Clear Creek runs east through Clear Creek Canyon from Idaho Springs, enters Jefferson County, passes through Golden, and continues northeast through Arvada toward the Denver border. The Clear Creek corridor through Golden and the Greenbelt area in Arvada has FEMA flood zone coverage. Properties near Clear Creek in downtown Golden and along the creek greenway in Arvada may need elevation certificates when purchasing flood insurance or applying for building permits near the creek.
Mountain and Foothills Flood Risk
Mountain communities in Jefferson County face a different type of flood risk: canyon flash floods and spring snowmelt runoff. Evergreen has Bear Creek running through it, with some flood zone coverage. Conifer and Bailey are in the South Platte River watershed; localized creek flooding is a seasonal risk. Morrison sits at the entrance to Bear Creek Canyon, with creek flood risk.
Mountain elevation certificates run toward the higher end of the county cost range, $550 to $900, because of terrain access time and the additional complexity of measuring elevations in canyon or steep hillside settings.
What the Certificate Does
A licensed Professional Land Surveyor measures the lowest floor of the structure, referenced to NAVD 88, and compares the result to the Base Flood Elevation on the current FEMA FIRM panel. The completed FEMA Form 086-0-33 documents your flood risk position. Properties above the BFE pay lower NFIP premiums; properties at or below the BFE pay higher rates or may be required to carry flood insurance as a condition of a federally-backed mortgage.
