If you are planning a project in Clean Water Services' jurisdiction we are here to work with you. If your project is in Beaverton, Cornelius, Forest Grove, Hillsboro, Sherwood, Tigard or Tualatin you will need to work with your city. The permitting process is intended to be comprehensive and depending on project scope, may include review for environmental, sanitary, stormwater and erosion control impacts.

Any construction on your property including remodeling, adding a deck, driveway or fence, re-landscaping or demolition will require review and may require a permit through Limited Development Review. Exceptions to this review include any interior remodel that doesn't change the footprint of the structure, alter the ground or increase impervious surface. Find steps for your process below.
