The Department is committed to preserving the unique island environment while encouraging sensitive and quality development. Work in the department is conducted by teams of employees organized by the product and service priorities of the City. These include Land Use/Planning, Building/Inspection, Utilities/Right of Way, and Permit Coordination. See below to get the information you need!
