Community Impact Mitigation Fund Payments
Residents directly affected by the Denver Water Gross Reservoir Expansion Project will be considered for impact mitigation payments in two phases:
- Phase I payments were distributed in 2023 and 2024 based on the full 7-year community impacts from the Gross Reservoir Expansion Project.
- Phase 2 payments will be determined based on projected impacts from the tree removal operations projected to begin in mid- to late-2027. (See more under “Phase II Payments – Pending.”)
Phase I Payments – Completed
Boulder County completed the first round* of payments from Section 2. “Reduce Impacts to Residents” of the Denver Water Settlement Agreement on April 30, 2024. See Gross Reservoir Community Impact Mitigation Fund Phase I Distribution Report for full payment details.
Phase II Payments – Pending (as of October 2026)
Conversations with Denver Water staff indicate that the tree removal phase of the Gross Dam construction project will not begin until mid-2027 at the earliest. Denver Water’s plans for tree removal and other associated activities related to Denver Water’s Gross Reservoir expansion project were postponed for two years by a federal district court case (Reference: Save the Colorado et. al. vs. U.S. Army Corps of Engineers and Denver Water). The court’s final decision in September 2026 allows Denver Water to move forward with the remaining construction plans, including the removal of trees around the reservoir.
Boulder County is waiting for Denver Water to disclose its schedule for tree removal and related activities. These plans are not expected until the spring of 2027. At that time, Boulder County will evaluate a process for distributing Phase II payments. Sign up for Boulder County’s Gross Reservoir newsletter to receive news and updates.
