Transportation Concurrency and Level of Service Interim Development Regulations

On November 20, 2018 the City Council adopted interim development regulations, O2018-477 which adds road segments and corridors to the City’s existing transportation concurrency program and level of service standards. This new Ordinance is in effect for six (6) months from the effective date of this ordinance of December 1, 2018. Sammamish Municipal Code chapters affected by this ordinance include 14A.05, 14A.10 and 21A.15. The City Council will hold a Public Hearing on the Ordinance establishing these interim development regulations at their regular business meeting on January 15, 2019.

The adopted interim development regulations result in a failure to meet the corridor LOS along the Sahalee Way – 228th Avenue N. corridor (NE 12th Place to the north City limits).  The City Council is continuing to work on addressing the failure. In regards to implementing the interim development regulations, the code states that the City will run a concurrency test after permit applications have been received that collectively result in 10 or more trips during an individual peak hour. However, since the interim development regulations include a corridor that fails the City’s LOS standards, the City has been advised that it cannot issue a concurrency certification if a project adds any peak hour trips to the Sahalee Way-228th Avenue N. corridor until that failure is addressed.  This means the City will perform a concurrency test for all projects and will not issue a concurrency certificate if it results in adding one or more peak hour trips to said corridor.
