Stormwater Criteria


The Stormwater Criteria Manual sets stormwater policies and provides drainage criteria for all new stormwater design and construction activities.

City Council adopted the manual December 2011 with Ordinance 174, 2011 (PDF 4MB). The manual incorporates most of the Urban Drainage and Flood Control District (UDFCD) Manual with amendments that are unique to Fort Collins. The Fort Collins table of contents (PDF 248KB) lists whether the criteria was adopted, amended or deleted.

In February of 2013, City Council adopted the LID policy and criteria in Ordinance 152, 2012 (PDF 110KB). Detailed LID criteria are incorporated in Volume 3, Chapter 3 of the manual below.
