Development Review and Engineering Resources
Are you developing in the City of Sammamish?
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 development.
Drainage review may be required if applying for land use permits, building permits, or clearing and grading permits. Go to the Drainage/Surface Water Standards and Forms page.
Any work or impact to traffic in public right-of-way must obtain a Right-of-Way permit. Go to the Right of Way Use Permit page.
