King County Georgetown CSO
This project was part of a larger Combined Sewer Overflow (CSO) Control Plan Amendment to reduce combined sewer overflows into local water bodies, protecting public health and the environment.
Furtado & Associates (as L&A at the time) provided base mapping, utility surveys, and other survey services for Georgetown Wet Weather Treatment Facility. For this project, F&A supplemented base mapping of the topographic and planimetric features on privately owned parcels. F&A provided field scanning in order to obtain survey information both to expedite the field survey activities and to allow initial work to occur from outside the property limits. Initial scanning allowed base mapping of portions of the site accessible and within view from surrounding properties and public right of way where right of entry was available. The parcels were scanned to create a base map for preliminary site development planning. Scanning also included the underside of elevated roadways and overhead power lines near the proposed outfall site for the purposes of determining overhead clearances for construction and locations of bridge columns along the preferred conveyance route from the treatment plant to the outfall.
