Susan Genes, Cowlitz County engineer, briefed the commissioners on a SEPA-related proposal from Granite Construction tied to a project in Woodland. Granite offered to perform an overlay on a section of Dyke Road as part of SEPA mitigation, while the county seeks funding to reconstruct that portion of road in a 5–10 year timeframe.

Genes said Granite and county staff also met with the local diking district and reached an understanding that truck traffic on Dyke Road would be restricted during prolonged high-water events. "They met with, the diking district down there because this road is on the dike and came to an agreement that they would, restrict the truck traffic on Dyke Road during high water events," she said. The parties discussed using an elevation trigger based on the diking district's historical observations; when water is up at that elevation for more than 24 hours the district has observed movement ("pumping") in the road foundation.

Genes clarified the diking district remains responsible for dike maintenance while the county is responsible for the road surface; the county holds a waiver to operate and maintain a road atop the dike. She said the diking district plans a foundation study to assess whether reinforcement will be necessary.

Commissioners asked whether limiting truck traffic would affect Granite's operations; Genes said Granite was amenable because the heaviest hauling generally does not occur during the periods when high-water saturation causes instability. The board signaled it was willing to pursue an agreement that would include the overlay mitigation from Granite and the diking-district restriction conditions.

Genes emphasized the agreement would require formal board authorization to proceed with the county entering into an arrangement with Granite and the diking district. "So that is, the proposal from them for the county. And in addition to that, they met with, the diking district down there... So I was being asked if we were willing to move forward with those conditions, and I wanted to bring it to the board to see if they were willing to come to an agreement because it would require us entering into an agreement, with Granite to get this taken care of," she said.
