Proposed City and County of Denver Flood Map Reflects Changes to Local Flood Risk, Insurance Rates

Release Date Release Number
Release Date:
May 13, 2021

DENVER – The City and County of Denver flood insurance rate map update for Harvard Gulch and Dry Gulch Tributary, Sanderson Gulch, and Sloan’s Lake Drainageway is nearing completion. The new maps will provide Denver with more accurate flood risk information that can help local officials and residents make informed decisions about reducing flood risks and purchasing flood insurance.

The mapping project is a joint effort between the City and County of Denver and the Mile High Flood District. It is part of a nationwide effort led by FEMA to increase local knowledge of flood risks and support actions to address and reduce those risks.

Before new flood insurance rate maps become effective, there is a 90-day appeal period during which local residents and business owners can provide additional data for consideration before the maps are final. This appeal period starts on May 21, 2021.

Residents and business owners are encouraged to review the proposed flood insurance rate maps to learn about flood risks, potential future flood insurance requirements, and any concerns or questions about the information provided.

You may submit an appeal package during the 90-day appeal period. Appeals must include detailed information indicating that the flood hazard determinations proposed by FEMA are scientifically and/or technically incorrect.
