WELCOME

The Boxelder Basin Regional Stormwater Authority was created in August 2008 by Larimer County, the City of Fort Collins and the Town of Wellington in accordance with Colorado Revised Statute 29-1-203 by intergovernmental agreement (IGA).

Authority Responsibility – The Authority is responsible for the implementation (including design, construction, operations and maintenance) of regional improvements of the adopted Boxelder Stormwater Master Plan (Master Plan). The configuration of these regional improvements have changed since the original Master Plan due to site constraints and right of way issues.  The three principal projects have now been constructed they include:

  1. The Coal Creek Flood Mitigation Facility at Clark Reservoir has been dredged and the spillway has been expanded to add floodwater capacity to the existing water storage facility.  This reduced stormwater flows in Coal Creek and Boxelder Creek downstream of this facility.
  2. The East Side Detention Facility (ESDF), a stormwater detention facility adjacent to the Gray Lakes Irrigation Reservoirs, and across I25 from the Budweiser Brewery north of Fort Collins.  This facility will substantially reduce stormwater flows along Boxelder Creek south of ESDF
  3. The Larimer Weld Canal Crossing Structure which is a side flow spillway on the Larimer Weld Canal located about one mile south of ESDF which will control stormwater flows overtopping the canal in the 100-year event.

The Letter of Map revision (LOMR) submittal to FEMA for the last two projects mentioned above is now in process and is further detailed in Manager’s Corner section of this website.

The improvements will reduce the hazard of flooding to many existing houses, two schools, several government buildings and many commercial buildings located in the Lower Boxelder Community. Many commercial buildings near the intersection of State Highway 14 and Interstate Highway 25 are subject to flooding and will no longer be subject to flood damages as well. While reducing the potential for damage benefits the owners of the respective properties, the community will also benefit from the increased economic vitality of these areas. FEMA rules require owners of properties located in flood hazard areas to purchase flood insurance if they are financed by a Federally regulated institution. FEMA also requires local governments to enact land use restrictions in flood hazard areas so that additional improvements will not be put at risk. Owners who are freed from the burdens of flood insurance and land use regulation will be more inclined and enabled to put money into their properties. This will benefit the community by increasing property values.

Public safety is a concern in times of flooding, and emergency response providers are required to respond to private and public needs. Sanitary sewers may become hydraulically overloaded due to interception of floodwater causing backup of raw sewage into homes and businesses. The reduction in flood hazard brought about by the planned improvements will benefit the Lower Boxelder Community by reducing the demand on emergency response resources when a flood occurs.
