Commissioners approve Black Lake Quarry rezone to rural‑resource industrial after environmental debate

Thurston County commissioners voted Dec. 2 to rezone an existing gravel‑mine site near Black Lake to Rural‑Resource Industrial (RRI) with an exclusion of approximately 24 acres identified by state and federal partners as Oregon spotted frog habitat.

What the change does: rezoning the disturbed quarry area to RRI would allow rural industrial uses tied to resource sectors (forestry, mining, agriculture) while keeping the most environmentally sensitive parcels in a more protective designation. Planning staff emphasized the siteads current mining use predated county critical‑areas and shoreline protections; any future development under RRI would need to comply with those modern standards.

Environmental concerns and reclamation: public comment and several commissioners raised questions about hydrology, aquifer recharge, and whether the stateads reclamation requirements (which focus on safety and slope stabilization) match community expectations for habitat restoration. Planning staff confirmed that reclamation obligations (regrading and fencing and a financial bond) differ from voluntary restoration plans some commenters advocated, and that the countyads environmental review would apply to any proposed future uses.

Why proponents supported the rezone: supporters argued the parcel is already ecologically disturbed by mining and that RRI zoning could enable facilities that support local agriculture (cold storage, processing) and reduce development pressure on farm and habitat lands elsewhere in the county.

Vote and next steps: after prolonged discussion and questions from commissioners about groundwater and species protections, the board adopted the rezone application as presented and directed staff to implement the zoning change consistent with the agreed exclusions and environmental protections. Staff said mitigation, critical‑areas review and any shoreline permitting would be applied to future development proposals.
