Gross Reservoir Impact Mitigation Fund Award Claims Are Being Processed

Please allow up to 60 days to receive an award payment due to the high-volume of requests

Gross Reservoir Community Impact Mitigation Fund – Phase 1 Distribution

Payment award letters totaling $4 million in payouts approved by the Boulder County Commissioners for the Phase 1 Distribution were sent to eligible households in August using mailing addresses of record with the Boulder County Assessor’s Office.*

The Phase 1 Distribution methodology using Final Pinyon Rankings for air, noise, and visual impacts was applied to eligible property addresses to determine final payment amounts. 

Check Processing Time

Please allow up to 60 days from the date we receive your paperwork to be mailed a check. The process for verifying eligibility and recording award claims has many steps. We appreciate your patience as we get through the high volume of claims we've received. Please do not expect payment any sooner than 45 to 60 days since you sent in your paperwork or applied online.

More than $1 million in claims are already in the process of being paid. (Please note: No checks have been issued (or mailed) yet. As the county begins to issue payments, we will update the website with the total dollar amount of claims paid out.)

  • Boulder County will mail you a 1099-G in the beginning of the calendar year following the year you received an award payment (i.e., claims paid in 2023 will receive a 1099-G in the beginning of 2024).
