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. The improvements have a total estimated & updated cost of $15 million and include:

  • Adding floodwater capacity to an existing water storage facility (Coal Creek Flood Mitigation Facility at Clark Reservoir)
  • Construction of a new stormwater detention facility (called East Side Detention Facility), and
  • Middle Basin Improvements to direct floodwater away from the westerly flood flowpath.

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.
