Development Moratorium FAQs

Last updated March 21, 2018. (Please note: to be a timely resource for the community, this page will be updated as we gather more information about the ordinance and receive questions.)

I still see building and development throughout the city! Why?

  • The City of Sammamish has approximately two years of current and approved building permits in the pipeline. It will take some time for those projects to slow and for citizens to notice the moratorium’s impact.

What development will be allowed under the moratorium?

  • A full list of projects exempted from the moratorium is listed in the latest adopted moratorium ordinance, O2018-458.

What development will NOT be permitted under the moratorium?

  • Any building or development project that does not currently have a permit application on file with the City and does not fall into one of the expressly exempted categories in the Ordinance (O2018-458). If you have specific questions, contact the city’s Permit Center, (425) 295-0531.

How does the moratorium affect remodels?

  • The ordinance allows for additions and alterations to existing structures, with the caveat that such additions/alterations do not result in new units for existing multi-family or commercial structures. Permits will also be allowed for structures that replace pre-existing structures destroyed by fires or other unintentional disasters.

Does the moratorium affect tree-removal permitting?

  • During the moratorium, the City will grant permits for removal of significant trees (a coniferous tree with a diameter of 8 inches or more or a deciduous tree with a diameter of 12 inches or more). Removal of hazardous trees is also allowed. If you have specific questions, contact the City’s Permit Center, (425) 295-0531.

When will the moratorium end?

  • A 6-month extension of the moratorium was implemented via ordinance O2018-458. It will end six months after the date of initial adoption (October 3, 2018) unless the City Council chooses to repeal or renew it.

What is a traffic-concurrency model?

  • Concurrency is required for planning under the Washington State Growth Management Act (GMA), and it refers to the responsibility of jurisdictions to provide public facilities and services in a timely manner. GMA requires jurisdictions to have strategies or a financial commitment in place concurrent with development and to complete those improvements or strategies within six years of development impact, which occur at the time of occupancy. Jurisdictions are required to develop a comprehensive transportation plan with established levels-of-service standards for arterial roads and transit services.  Here is a good resource about how traffic-concurrency planning fits into the state’s and cities’ growth-management acts throughout Washington.

How can I be involved in the traffic planning?

  • The City Council will discuss traffic concurrency at many of its meetings until a revised policy and model is implemented. Citizens are welcomed and invited to attend (the Council’s full calendar is available at  You can also contact the Council directly at
