Hi,

Here’s a link to Clackamas County’s Erosion Prevention Guidance and Standards..

Here’s a link to the Construction Entrance Detail Drawing. Including a detail they can use to keep the existing curb in place.

They will also need to place erosion control at any inlets downstream of the entrances.

I would also require silt fence on downhill slopes at the property lines. Trucks can create rutting resulting in dirty runoff during storm events on to neighboring properties.
