Snohomish County Planning & Development Services (PDS)Snohomish County adopted a Mineral Resource Lands (MRL) in Map 2 of the Future Land Use Map on February 1, 2006, designating and protecting land containing mineral resources of long-term significance. The MRL designation overlays other land use designations, and is intended to (1) limit mineral activity to areas within the MRL, and (2) restrict intense rural land uses within the MRL to preserve future access to the mineral resources. A 1999 mineral lands inventory identified 177,000 acres of mineral resources in Snohomish County. Of the 177,000 acres identified in the inventory, 131,000 acres are designated in the MRL. The MRL represents all of the mineral resource deposits in the county which meet the criteria for volume, quality, and extractability; are under county jurisdiction and are not slated for more intensive urban development; and are located in predominantly undeveloped, low density rural or forest areas where land use and environmental incompatibility issues have been addressed at a countywide level.
