Floodplain Management

Flood Floodplain management involves use of policies and floodplain regulations to protect the health and safety of citizens and reduce the risk of property damage in flood-prone areas. The effort also includes providing the public with information and promoting awareness of flooding hazards and ensuring compliance with Federal Emergency Management Agency (FEMA) requirements.

Effective flood hazard mapping can be viewed on the Weld County Property Portal under the Land Use Layers or on the FEMA National Flood Hazard Layer website.  The FIRM index date for Weld County is November 30, 2023.

FEMA is in the process of updating three panel maps that affect Weld County.  The area under review is part of the Boulder Creek and Saint Vrain floodplains (panel maps #1860, 1870, and 1890).  These three Preliminary FIRM maps are considered best available data and have an issue date of March 23, 2022.  The preliminary mapping can be viewed on the Weld County Property Portal under the Planning Layers or on the Colorado Water Conservation Board Hazard Mapping website or on the FEMA Map Service Center.

Please contact Melissa King at (97) 400-3762 or mking@weld.gov or Diana Aungst at (970)-400-3524 or daungst@weld.gov for information about the floodplains and how to submit for a Flood Hazard Development Permit (FHDP) for all development, new construction, pipelines, or expansion or buildings.  A Floodplain Permit (FP) is required if the work is internal to a building.
