As part of a worker safety upgrade and regulatory compliance project, the Multnomah County Drainage District was granted approval of an Environmental Review covering five site development areas for:

• Re-grading existing grade and placing gravel for an approach used for worker access
• Installation of fall protection structures (concrete vaults) to be placed over the upstream edge of the existing culverts
• Temporary excavation below the culverts to place gravel below the vaults
• Railing installation on the platforms of the vaults
• Improvements of access paths to the structures, including installation of stairs
• Temporary staging areas and construction access
• Permanent fill around the structures to provide bank stability and smooth hydraulic transitions

We were excited to see the final product Mid-July!

We have a long history of working with the Multnomah County Drainage District, and we have some of our more elaborate projects outlined in our portfolio.
