Construction requirements

Sign Requirements: Subdivisions breaking ground after July 27, 1998, are required to place a Construction Notice Board at the site - see Notice of Construction Activity Sign Requirements . A copy of the latest detail of the Permanent Surface Water Control Pond Sign is also available.

Certificate of Insurance Requirements: If you are working under a clearing or grading permit, OR are required to construct a drainage facility as a condition of your permit approval, King County Code 16.82.090 and 09.04.100(D) requires the applicant to obtain a Certificate of Insurance that names King County as an additional insured. This insurance is required to protect King County from property damage and/or liability caused by any accident, negligence, failure of a drainage facility, or any other liability relating to work on the site and may cover maintenance of required drainage facilities. A contractor may post the insurance on behalf of the applicant, but all contractors, including subs, must also post the insurance.

In order to obtain this insurance, contractors/applicants shall submit to DPER an Acord Certificate of Insurance and a copy of the Additional Insured Endorsement. King County prefers CG2010 (Form B) be used. However, if your insurance company does not use the standard Form B, you may submit a substitute and our Risk Manager will review and either approve or deny the substitute form. For more information, see Grading & Reclamation Liability Insurance Requirement or drainage facilities insurance .
