Draft Storm Drainage Criteria Addendum, 3/20/2020 [PDF]

In 2002 the City of Loveland Storm Drainage Criteria (Addendum to the Urban Storm Drainage Criteria Manuals Volumes 1, 2, and 3) was completed and adopted.   The City of Loveland Storm Drainage Criteria Manual was modeled after the 2001 version of the Urban Storm Drainage Criteria Manual as developed by the Urban Drainage & Flood Control District (UD&FCD) in Denver, Colorado.  The 2001 version of the UD&FCD Storm Drainage Criteria Manual consisted of Volumes 1 & 2.  Late in the 1990’s the UD&FCD began a process to write Volume 3 titled, Best Management Practices, which addresses stormwater quality and erosion control.  In November 2010, the UD & FCD completed and adopted an updated Volume 3. In January of 2016 the UD&FCD completed and adopted updated Volumes 1 and 2 to their drainage criteria.  Many communities use the UD&FCD storm drainage criteria manuals across the United States.

The City of Loveland is updating our addendum to more easily follow the criteria set forth in the updated 2016 UD&FCD Volumes 1, 2, dated January 2016 and UD&FCD Volume 3, dated November 2010.  The City of Loveland is currently working towards adoption of the latest UD&FCD Volumes 1, 2, and 3 with an Addendum relating to City of Loveland needs.  The Addendum will make changes to the UD&FCD Volumes 1, 2, and 3 in order to help the criteria become more specific to the Loveland community.  Adoption of the UD&FCD Volumes 1, 2, and 3, as well as the City of Loveland Addendum, is scheduled for late 2020.
