Development Review, Permitting, and Engineering Resources

Are you developing in the City of Sammamish? If you are applying for a land use permit, building permit, or clearing and grading permit, drainage review may be required. Any work or impact to traffic in public right-of-way must obtain a Right-of-Way permit.

The Development Review Engineering team reviews, permits, and inspects the construction of new roads, storm water utilities, right-of-way improvements, and erosion control associated with the development of private property. For more information on the land use and permitting process, visit the Department of Community Development web page.
