Santaquin City Watershed (Sponsor=Santaquin City, Utah)

Project Description

The United States Department of Agriculture Natural Resources Conservation Service (NRCS), with Santaquin City as the project sponsor, is proposing to partially fund watershed protection measures through the Watershed Protection and Flood Prevention Act (Public Law [PL] 83-566). The work measures are being proposed within the Santaquin Watershed (East Bench) to 1) prevent flood damages, 2) further the conservation, development, utilization, and disposal of water, and 3) further the conservation and proper utilization of land.

NEPA Analysis

NRCS, as the lead federal agency, is initiating National Environmental Policy Act (NEPA) analysis in the form of a Supplemental Watershed Plan and Environmental Assessment (Plan-EA) to analyze impacts to the natural and human environment from this project. The Plan-EA 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. The Plan-EA is a supplement to the original Santaquin Watershed work plan authorized in 1954.

Current Status

The project has finished the Scoping Phase where the public, organizations, and agencies were invited to provide comments on the proposed project. Currently, resource and alternatives analysis are completed and a Draft Final Supplemental Plan-Environmental Assessment (Plan-EA) is available for review starting September 9, 2019 until closing of the comment period on October 15, 2019. The public is invited to attend a Draft Environmental Assessment public meeting, which will describe the alternatives analyzed and potential impacts to the environment from the project. Information for this meeting and the comment period is given below.

Draft Plan-EA Introduction

The NRCS is proposing to partially fund the project through the Watershed Protection and Flood Prevention Act of 1954 (PL83-566) and the Draft EA has been prepared in compliance with the National Environmental Policy Act (NEPA) per 40 CFR Parts 1500-1508.

Project Purpose and Need

The purpose of the project is to control and prevent stormwater flooding and associated debris flow resulting from erosion off the east bench hillsides that constitute the Santaquin East Bench Watersheds from impacting private properties and public infrastructure. The objection of the project is to provide substantial flood reduction from the 100-year-storm event and to prevent flooding from the 25-year fire-related event and debris flow from the 5-year storm event (i.e., 20% chance storm). The proposed action is needed because currently the study area lacks natural drainage channels to convey stormwater and debris flow away from residential and commercial properties along Santaquin' s east bench and critical public infrastructure.

Public Involvement

Public participation is a vital component of the projects providing those who are interested in or potentially affected by the proposed projects with an opportunity to share comments, ideas, and/or concerns regarding actions during the Draft Plan-EA stage of the NEPA process.

Comments were submitted during the public comment period starting September 9, 2019 and ending on October 15, 2019.
