The Development Services Department is responsible for reviewing all development applications, street improvement plans and construction, and final plats to ensure conformance to District standards and policy. The Department consists of two Sections: Planning Review and Development Review.

Development Sections The Roles of Each

The Planning Review Section is responsible for the review of all development applications within Ada County and the six cities within Ada County. The Section reviews and assesses the potential impacts proposed developments will have on the transportation system, and analyzes and evaluates the preliminary development proposals for conformance to current District policies and standards.

Staff prepares reports, including the District’s site specific conditions of approval, and presents the staff recommendations to the ACHD Board of Commissioners for action.
