Project Scope: Routine inspection identified cracks in a large concrete box culvert, and pinholes in a 6-ft metal arch culvert, at / under our Main Pump Station. We’ve hired a local contractor to make structural crack repairs and spray line the culvert using a heavy epoxy coating with a 50-year life. If you’ve noticed Ditch 6 is low, this is why!
Benefit: Infrastructure improvement.
Motor Reconditioning - Main Pump Station Motors #1 and #8
Date: In Progress
Project Scope: Our motors are statically and dynamically tested annually to check for vibration and signs of deterioration in the bearings and windings. CDID#1 pulled two motors in July for bearing replacement and reconditioning after detecting higher than normal vibration. Both motors will be re-installed later this summer.
Benefit: Equipment readiness and reliability.
Ditch 10 Benching
Date: In Progress
Project Scope: CDID#1 contracted with a local contractor to bench Ditch 10 at Schneiter Drive. Benching provides better access to get equipment in alongside the ditch for vegetation removal, and reduces the potential for bank sloughing.
Benefit: Improved access and maintenance.
Main Pump Station Gear Upgrade
Date: In Progress
Project Scope: CDID#1 contracted with a local independent electrical contractor to replace and upgrade the main switchgear and motor control center at our Main Pump Station to provide arc-flash mitigation and smart control.
Benefit: Safety and reliability enhancements.
West Side Highway Storage Facility
Date: July 2019
Project Scope: In the event of a flood, a temporary flood wall will be constructed across West Side Highway to close the Cowlitz River levee near Fishers Lane. CDID#1 contracted with a local builder to construct a secure storage building and lay-down area to house flood fight equipment and supplies.
Benefit: Emergency readiness.
Ditch 12 Tree Removal
Date: April 2019
Project Scope: CDID#1 partnered with Weyerhaeuser Real Estate Development Company to fall (64) cottonwood trees in excess of 120-feet tall along Memorial Park Drive. Several trees had trunk rot and beaver damage and posed a threat to nearby homes, high voltage power lines and CDID#1 conveyances.
Benefit: Safety and reliability enhancements.
36th Avenue Trash Rack
Date: November 2018
Project Scope: CDID#1 partnered with the City of Longview to construct a trash rack on Cutoff Slough where twin 60-inch culverts require frequent maintenance to remove blockages. The new trash rack protects the culverts, screens out debris and provides access for maintenance equipment.
Benefit: Improves flow and water quality.

48th Avenue Debris Boom
Date: October 2018
Project Scope: Heavy rainfall causes thick mats of aquatic weeds to stack up in front of the 48th Avenue pump station until choked flow shuts off the pumps. To improve operation, CDID#1 constructed a debris boom and landing area to mechanically remove weeds upstream of the pump station.
