Land Use and Planning Advice: Tips for Success
Research Site History
Check your title report for special conditions or restrictions related to the development of your property. The City has individual 'street address' files for many of the lots on Mercer Island with information on past development and activities that you may wish to review. Use our map portal and mybuildingpermit.com to review specific site history online.
Base your project on an Accurate Site Plan
Obtain a site survey prepared by a registered Washington State land surveyor of your property, with two-foot contours, showing all existing natural and built features. This site survey is to be used as a base for your site development plans.
Comply with all Unified Land Development Code (ULDC) Requirements
Review the development regulations that pertain to the site - after viewing, ask questions to clarify! City's Unified Land Development Code (MICC Title 19).
Obtaining Federal and State Permits
If you are doing work within a watercourse corridor and/or wetlands in or within 200 feet of Lake Washington, consult with state and federal agencies about the scope of your project to find out early in your design process if there are any special concerns or modifications that should be made prior to submitting for City approval.
Contact the Department of Ecology Permit Assistance Center to obtain statewide environmental permit information and see if your project plans need modification. Call (360) 407-7037 to find out which environmental permits are required for your proposed activity.
Review the Comprehensive Plan
If applicable, obtain a copy of the City's Comprehensive Plan and review the elements that pertain to your project.
Use Quality Design Professionals
Hire top-quality design professionals—this is the single most important factor in the success of your project. The quality of your plans and project presentation directly reflects the overall quality of your application.
To verify that your construction, electrical, or plumbing contractor meets Washington State's legal requirements, consult the Washington State Department of Labor and Industries at 1-800-647-0982 or use their online contractor database.
Respect the Character of the Neighborhood
Carefully consider the full lifespan of the project, its intended use, and how it will contribute to the community. Keep in mind that a development's impact extends beyond its property lines.
Plan Ahead
Be sure to allow enough time to research, plan, and design your project, as well as to apply for, revise, and obtain any required City, state, or federal permits.
Maintain Public Contact
You may wish to meet with neighboring property owners to discuss your proposal prior to filing the application.
