GeoDesign (now NV5) has provided mining consulting and geological services to the Port of Tacoma for over a decade for the Maytown Aggregates Pit in Thurston County. NV5 performed an aggregate resource investigation including a geomorphic analysis of the glacial geology affecting the mine property, a sonic drilling investigation of the aggregate material, and laboratory testing. These data were used to develop a subsurface geologic model for the aggregate resource, which controlled the overall development plans.
NV5’s role in mine plan development included coordinating with multiple managers and departments within the Port of Tacoma, as well as with the owners of Maytown Aggregates, who purchased the property from the Port. We served as a liaison for the Port of Tacoma with overseeing agencies for many complex permitting issues and development of plans for surface-mine operations.
The Port now is sole owner of the property, and NV5 has assisted the Port in maintaining all of the mining-related permits for the site to preserve its highest and best use for eventual sale of the property. NV5 is currently assisting the Port through another 5-Year Review of the special-use permit (SUP) with Thurston County.
