Bank Stabilization Monitoring on South Boulder Creek and North Fork South Platte
Request for Proposals (RFP)
Submission Deadline: 2:00 pm (MT), Wednesday, July 8, 2026
Section 1 – Introduction, Background, & History
Introduction
Denver Water is seeking a firm to monitor bank stabilization on South Boulder Creek and the North Fork South
Platte River. The selection process involves interested firms submitting a proposal to complete monitoring and
reporting activities on both streams; followed by consultant interviews, selection, and contract award.
Background & History
Denver Water began the process of permitting the Gross Reservoir Expansion (GRE) Project in 2003. The U.S.
Army Corps of Engineers was the lead federal agency in regard to preparation of the Environmental Impacts
Statement (EIS) and issued a Clean Water Act Section 404 Permit in 2017. Prior to issuance of the 404 Permit,
Denver Water entered into two agreements requiring monitoring of stream bank stability below transmountain
diversions. The first was with Colorado Parks and Wildlife (CPW; 2011) and the second was with the U.S. Forest
Service (USFS; 2016) which was adopted into Denver Water’s 2020 Federal Energy Regulatory Commission
(FERC) License for Gross Reservoir hydropower operations.
Section 2 – Phase 1 Overview
Consultant Scope of Work Overview
Based on the requirements listed below, develop a scope of work (SOW) to meet the field monitoring
requirements and prepare one annual report for CPW and the USFS for each year field monitoring takes place.
Project Assumptions
The following assumptions were made in the development of this SOW:
• This project will be developed and coordinated in Denver Water’s SharePoint platform. Denver Water
will utilize the existing GRE Project SharePoint site and will establish a Microsoft Teams channel for
collaborative use by the internal and external project design team members.
• The Consultant’s SOW shall be focused on meeting the requirements of the streambank monitoring
program shown below. Contract amendments for additional scope will be considered by Denver
Water based on the Consultant’s performance and project progress.
o Phase 1 will be for monitoring and reporting of baseline conditions (Baseline Streambank
Monitoring and Reporting).
o Phase 2 will be for monitoring and reporting during initial fill of the expanded reservoir (Initial
Fill Monitoring and Reporting).
o Phase 3 will be for monitoring and reporting post initial fill of the expanded reservoir (Long-
term Monitoring and Reporting).
• The initial funding approval will cover Phase 1. Subsequent funding for Phase 2 and Phase 3 will be
approved utilizing contract amendments.
