Development Services

We administer sanitary sewer, surface water management, and erosion control programs in urban areas of Clackamas County.

Plan review and permitting are part of the broader land use and permitting process in unincorporated Clackamas County, the City of Happy Valley and Rivergrove. We review and approve all public and private sanitary, storm and erosion control plans for development activities such as:

  • Any activity that requires a building permit: construction of structures, roadways and utilities
  • Grading or excavating
  • Land division, including subdivisions, land partitions and lot line adjustments
