Grove Creek Debris Basin Rehabilitation

Project Description

The Natural Resources Conservation Service (NRCS) is analyzing alternatives to rehabilitate Grove Creek Debris Basin located at the foothills within Pleasant Grove, Utah.  NRCS performed an assessment of Grove Creek Debris Basin in 2005.  The 2005 assessment concluded that the Grove Creek Debris Basin does not meet current NRCS and Utah State Dam Safety regulations and engineering standards for a high hazard dam (potential “Loss of Life”).  The purpose and need for this project is to meet current USDA-NRCS and Utah State Dam Safety regulations and current engineering standards, and to continue to provide current benefits for the authorized purposes of flood prevention and sediment retention.  The project would restore the design storage capacity in the reservoir by raising the water level, enlarging the spillway to pass the Probable Maximum Precipitation (PMP) event, and provide slope stability for seismic events.

NEPA Analysis

This project is being partially funded by the NRCS Small Watershed Rehabilitation Amendments (PL 106-472) which authorizes funding and technical assistance to rehabilitate aging flood control dams built under the Small Watershed Program (PL 83-566).  NRCS, as the lead federal agency, is initiating NEPA analysis in the form of a Supplemental Watershed Plan and Environmental Assessment to analyze impacts to the natural and human environment from this project.  The Environmental Assessment will comply with the Council on Environmental Quality’s regulations at 40 CFR Parts 1500-1508 which require an evaluation of potential environmental impacts associated with federal projects and actions.  This debris basin is controlled by the North Utah County Water Conservancy District which is the project sponsor.

Current Status

The NRCS has prepared a Draft Supplemental Watershed Plan-Environmental Assessment (Draft Plan-EA) describing the proposed rehabilitation of the Grove Creek Debris Basin.  The Plan-EA presents the alternatives analyzed, potential impacts to the environment, and the Preferred Alternative for the project. The public is invited to comment on the Draft Plan-EA during the specified time period below and attend a Draft Plan-EA public open house.
