Projects - Moffet EIS

Denver Water Moffat Collection System Environmental Impact Statement, Colorado. 

Project Description:

ERC is part of a third party consulting group working under the direction of the Army Corps of Engineers to prepare an Environmental Impact Statement for Denver Water’s Moffat Collection System Project. The purpose of the Moffat Collection System Project is to develop 18,000 AF (AF) per year of new, annual firm yield to the Moffat Treatment Plant. ERC was involved in the identification and screening of alternatives. More than 300 water supply sources and infrastructure components were identified and evaluated. Several of these options included on-stream and off-stream reservoir storage sites and enlargements of existing reservoirs. Ground water storage and the use of gravel pit operations were also investigated as were several options involving new institutional arrangements with other water users. ERC was involved in the review of Denver Water’s PACSM Model for use in analyzing hydrologic impacts of project alternatives. ERC reviewed PACSM modeling of Moffat Project EIS alternatives, assisted in generating and summarizing hydrologic model output for the analysis of surface water effects, and coordinated with resource specialists for analysis of other affected resources including aquatics, riparian habitat, recreation, and socioeconomics. ERC is part of a team responsible for evaluating and summarizing differences in hydrology for the EIS alternatives, Baseline scenario and No Action alternative.
