Chubbuck authorizes mayor to join Eastern Snake River Plain aquifer mitigation plan, pending legal review

The Chubbuck City Council voted June 17 to authorize the mayor to enter into an agreement to participate in the Eastern Snake River Plain Aquifer Cities mitigation plan, subject to review by the city attorney and the mayor’s final approval.

City staff explained the background: the Department of Water Resources issued curtailment orders that affected groundwater rights broadly, requiring the city either to secure mitigation coverage for additional water rights or reduce pumping. Staff said the city had historically participated in a different mitigation arrangement at a cost of about $20,000–$25,000 per year to cover a portion of its rights. Under the Eastern Snake River Plain plan, staff reported the city's share would be just under $14,000 annually, representing a savings compared with that prior arrangement.

The chair moved to authorize the mayor to sign an acceptable contract to participate, with the condition that the agreement meet review by Ryan Lewis (city attorney) and the mayor. Council voted unanimously to approve the authorization (Reese, Heiner, Hernandez, Evans yes).

Why it matters: Joining a regional mitigation plan preserves the city's existing groundwater access levels by paying into a mitigation pool rather than reducing water use; the move addresses immediate regulatory pressure from curtailment orders.

Next steps: Staff will proceed with contract execution if the city attorney and mayor approve the final agreement and will make the required payment by the July 1 date staff cited if the agreement meets review.
