Clear Lake Council reviews cannabis project with minimal groundwater impact claims

During the City of Clearlake City Council meeting on January 6, 2022, a significant discussion centered around the approval of a cannabis facilities project at 2185 Overland Canyon. The council heard from various stakeholders regarding concerns about the project's potential impact on local water wells and groundwater resources.

The applicant presented two technical memorandums indicating that the proposed project would have minimal cumulative impact on the surrounding area's water supply. They emphasized that the project's water demand would be only a fraction of the available groundwater resources in the Burns Valley Basin. Specifically, the project is projected to use 1.8 acre-feet of water, while the estimated aquifer recharge for the site is 4.2 acre-feet, even during dry years.

Angie Dodd from Northpointe Consulting Group, who was hired to assess the project's impact, addressed criticisms regarding the use of outdated data in the hydrology studies. She clarified that while some references date back to 2006, the geological formations and aquifer storage capacities have not significantly changed over time. Dodd highlighted that the project represents only 0.1% of the usable storage capacity in the basin and a mere 0.3% of the total potential future demand from all agricultural and residential uses in the area.

Despite concerns raised by local residents about the potential for wells to run dry, Dodd noted that existing monitoring wells in the basin have shown stable groundwater levels over time. She acknowledged that drought conditions could affect well productivity but emphasized that the project itself would not contribute to cumulative impacts on the aquifer.

The council's deliberations included a call for enhanced monitoring of groundwater resources to better inform residents about the health of their wells and the broader aquifer system. The meeting concluded with a request for the council to uphold the planning commission's decision to approve the conditional use permits for the cannabis project, reflecting a commitment to balancing economic development with environmental stewardship in the community.
