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 and work in the right-of-way must meet the Public Works Standards.

The Development Review Engineering team reviews, permits, and inspects the construction of storm drainage utilities, right-of-way improvements, and erosion control associated with the development of private property.
