Traffic Mitigation and Concurrency Ordinance (UDC Chapter 30.66B SCC)
Overview and Background
Update to Currently Adopted Public Works Rules
The Snohomish County Department of Public Works (DPW) is proposing to update Rule 4224 MAKING LEVEL-OF-SERVICE DETERMINATIONS FOR USE IN CONCURRENCY DETERMINATIONS. DPW proposes to amend sections of Rule 4224 to conform to the most current version of the Federal Highway Capacity Manual (HCM). The maximum service volume thresholds being amended are used to determine when the traffic volume on an arterial unit has reached the level that requires DPW to implement screening.

Interlocal Agreements (Reciprocal Traffic Mitigation)
Snohomish County has Interlocal Agreements (ILA’s) with the Washington State Department of Transportation (WSDOT) and numerous cities related to mitigation of traffic impacts from new developments. The agreement with WSDOT provides for the mitigation of traffic impacts to state highways caused by traffic generated from new developments in the unincorporated county. The agreements with the cities are ‘reciprocal’ in that they provide for mitigation of impacts on city streets from county developments and mitigation of impacts on county roads from city developments. View links below to the ILA’s and supporting forms and documents.
