Greeley presents Poudre River restoration vision and explores stronger local floodplain rules
Summary
Public Works staff outlined a multi-phase Poudre River Restoration Initiative focusing on floodplain function, ecological uplift and possible local floodplain regulation changes; staff said FEMA’s minimum standards may not capture local risks and that changes would be vetted with state and federal agencies.
City of Greeley staff presented an update on the Poudre River Restoration Initiative and signaled the city will explore stronger local floodplain regulations to reduce flood and geomorphic risk and improve river health.
"A healthy floodplain acts as a natural sponge, absorbing excess water during flood events and reducing the height and velocity of floodwaters downstream," Victoria Lenhart of the Public Works and Transportation Department told the Planning Commission. Lenhart said the restoration initiative takes a broad view of the corridor and the floodplain, not just the river channel, and aims to prioritize actions where ecological benefit, flood risk reduction and public access align.
Lenhart told commissioners the Poudre River within Greeley has narrowed since 1950 and that loss of floodplain connectivity has increased water speeds, bank erosion and loss of riparian habitat. The initiative uses a triage framework—conserve, enhance, create—to determine where intervention will yield the greatest ecological and public-safety benefit. Staff said the phase focused on urban reaches near downtown will examine targeted interventions where many homes and businesses lie within mapped flood hazard areas.
Lenhart emphasized that FEMA maps set minimum requirements under the National Flood Insurance Program but can miss local conditions. "FEMA sets minimum requirements through the National Flood Insurance Program, and communities must follow them. However, those are just the minimum," she said. Staff described work with Matrix Design Group to research best practices, assess code gaps and draft locally stronger regulations that align with Greeley's long-range planning; any proposed regulations would be coordinated with the Colorado Water Conservation Board, the Division of Water Resources and FEMA.
Commissioners raised practical questions about maintenance of preserved floodplain areas, gravel mining near the river, water storage in former pits, and how water rights and augmentation plans would be handled. Lenhart said the city is coordinating closely with its Water and Sewer Department, and Leah Hubbard, deputy director of Water Resources, has been engaged on implementation considerations. Staff said an augmentation plan may be required for some restoration activities and that such plans typically take about a year to develop and then additional time in water court.
Brian Hathaway, water quality and regulatory compliance manager, noted that the matrix work will include a legal review and coordination with the Division of Water Resources and FEMA. Staff also described a "Poudre Flows" effort by regional partners to add water to the river in trial programs.
The presentation was informational; staff sought input on potential policy directions to preserve floodplain function, require stronger development standards near the river and consider reclamation and buffer approaches for gravel mining and other uses that intersect the floodplain. No formal regulatory change was adopted at the meeting.
Ending note: staff said next steps include continuing stakeholder engagement, aligning floodplain work with sub-area plans and a development-code audit, and vetting any regulatory proposals with state and federal agencies before presenting recommended code changes to the commission and council.
