Approximately $11.25M was funded from State and Federal assistance programs and $1.5M from combined cost-match from City of Fort Collins, City of Greeley, and the Tri-Districts. Fort Collins has contributed $880,605, to date. Fort Collins Utilities also independently conducted work at the Poudre River water supply intake to protect raw water quality and the physical infrastructure, including: o Removed accumulated rock and sediment from the intake structure channel and modified the structure and installed a submerged concrete barrier in front of the intake opening to prevent rocks and sediment from entering the raw water pipe, o Repositioned the river channel immediately upstream of the intake structure to allow more effective transport of sediment downstream, and o Removed approximately 1,250 cubic yards of accumulated sediment from the Poudre River channel upstream of the water supply intake, about half of which was deposited after the Black Hollow debris flow that occurred on July 20, 2021. o The cost of this work was approximately $750,000. In total, Fort Collins has spent approximately $1.63M, or 33% of the original $5M appropriation for Watershed Wildfire Recovery. Additional expenditures are expected in 2022 and 2023, as additional recovery projects are completed. The 2021 voluntary Water Shortage Watch (Watch) ended on Oct. 1, 2021, pursuant to Fort Collins City Code Section 26-167(a) and the Water Shortage Action Plan, due to improving water resource conditions and less demand on water supplies with irrigation season ending. o Estimated water use during the Watch was 21 million gallons lower than the five-year average and a weather normalized analysis estimated that water use was 156 million gallons lower than expected given 2021 temperature and precipitation. Planned Work in 2022 In January, a revised Cameron Peak Recovery workplan for 2022-2023 was prepared by Ayres Associates and JW Associates on behalf of recovery partners. This updated workplan identifies the need for mulching on an additional 18,000 high-priority acres at an anticipated cost of $45M. This workplan is currently in-review by the US Forest Service (USFS), as most of the proposed work is on USFS lands. In addition, four erosion control projects started in 2021 will also be completed once work sites are snow-free. Additional on-the-ground projects have been identified, and if permitted and funded, will be completed in tandem with aerial mulching to maximize treatment effectiveness. Even with remaining funds awarded in 2021 and anticipated new funds in 2022, an approximate $25M funding gap remains to address even the highest priority needs. The City of Fort Collins, City of Greeley, and Northern Water continue to advocate to our federal and state delegations for timely and adequate funding for the wildfire recovery work, as our drinking water supplies and infrastructure remain vulnerable to debris flows and flooding from the untreated areas of the burn scar. In accordance with the Water Shortage Action Plan and following Northern Water’s issuance of the Colorado-Big Thompson (C-BT) quota on April 13 th, staff will meet on April 18, 2022, to develop a recommendation for a water shortage response (i.e., water restrictions) to the City Manager after evaluating water availability and the potential for a water shortage in spring and summer of 2022. o The recommendation will be based on water shortage indicators including drought conditions, basin snowpack, reservoir storage levels, C-BT quota, and water quality. While water quality is challenging to forecast, it is also expected to influence water availability to some degree, especially during the monsoon season. o The March 9 memo to the Water Commission includes additional details about the most recent water resource conditions.
