The Cache la Poudre River is the primary regulatory floodplain within the City of Greeley. However, multiple other regulatory floodplains exist within incorporated Greeley, including the South Platte, Sheep Draw, Coal Bank Creek, Ashcroft Draw, John Law Ditch, and Sand Creek.

The City of Greeley is a member of the National Flood Insurance Program (NFIP). Among other benefits, Greeley’s membership allows property owners to purchase flood insurance from the NFIP and makes our community eligible for federal disaster assistance and federal grants for flood hazard mitigation. This also means any development within regulatory floodplains in Greeley are subject to FEMA regulations (44 CFR § 60.3) and Greeley Municipal Code (Chapter 18.34, Article II)
The City regulates floodplains depicted on Flood Insurance Rate Maps (FIRMs). These FIRMs depict the expected extent of flooding as a result of the 1% Annual Chance Flood (formerly referred to as the 100-year flood). Meeting NFIP requirements in the floodplain is the most cost-effective way to reduce the flood risk to buildings and infrastructure.

Cache la Poudre RiskMap
The CWCB (Colorado Water Conservation Board) and FEMA (Federal Emergency Management Agency) are in the process of re-mapping the Cache la Poudre River floodplain. Results were released as Preliminary in September 2020, with the new map expected to be adopted in Spring 2022.
Any development taking place prior to Spring 2022 is governed by the current effective floodplain map; however, developers and homeowners are encouraged to evaluate the RiskMap as well as effective floodplain and to contact the City of Greeley Floodplain Administrator.
