    County Flood Services

    The FEMA National Flood Insurance Program provides County residences with significant discounts for flood prevention actions. Additionally FEMA flood maps are available through the Department of Community Development and are available in the Tillamook County Library. If requested, Community Development will do a site visit to review potential flood problems and explain ways to stop flooding or prevent flood damage. You may call the department at 503-842-3408. These services are free.

    What You Can Do

    Avoiding construction in the Special Flood Hazard Area is the best way to limit loss of life and property as the result of flooding. Contact the Department of Community Development (503-842-3408) to obtain any required permits for work in the mapped special flood hazard area.  Elevating your structure to the minimum standards of the NFIP is required and Tillamook County has elected to enforce stricter building code standards to both further reduce the risk of losses due to flooding and to increase the discounts provided through the NFIP Community Rating System program.

    Contact an insurance agent about your eligibility for flood insurance offered through the National Flood Insurance Program (NFIP). Don't wait until the last minute -- there is usually a 30-day waiting period before the policy is effective.  After a Flood If damage occurs, contact the County Department of Community Development (842-3408) for an inspection. Repairs are subject to permit requirements. Repair of substantial damage may require elevating the structure.  Encourage others to understand their flood risk and talk with an agent or find one at
