LEI Engineering and Surveying of Oregon completed the land surveying, civil engineering, and construction engineering/surveying for a 20,000 square feet expansion to the Swire Coca-Cola Facility in Bend, Oregon.  LEI Engineering and Surveying of Oregon performed as the land surveying and civil engineering team member for a design-build team led by Big D Construction out of Salt Lake City, Utah. 

Of specific importance for this project and site was stormwater treatment due to the site’s close proximity to a major drainage canal tributary to the Deschutes River.  The increase in impervious surfaces at the site resulted in an increase in stormwater runoff by over 4 cfs.   To treat this runoff, LEI Engineering and Surveying of Oregon designed a pair of drywells to treat 100% of the stormwater runoff for the site with the drywells, even up to the 100-year design storm.   Following the construction of the new dry wells, LEI Engineering and Surveying of Oregon performed the performance testing for the dry wells to verify their ability to treat the increased runoff flows.
