Aviation Land Use Compatibility Program - Example Scope of Work
Every county, city and town is required to adopt comprehensive plan policies and development regulations that will discourage the siting of incompatible uses adjacent to public use general aviation airports. (36.70.547 RCW) The Aviation Land Use Compatibility Program focuses on three areas that form a nexus around which decision-makers and stakeholders must craft responsible land use policies to preserve airports from the siting of adjacent incompatible land uses and to protect the health, safety and welfare of the community. They include height hazards, safety and noise. Many strategies are available to discourage the siting of incompatible land uses and WSDOT Aviation encourages the airport sponsor and the local land use jurisdiction to cooperatively work together to develop comprehensive plan policies and development regulations to meet their obligations under State Law. One of the first steps in addressing land use compatibility adjacent to public use general aviation airport should be the development of a scope of work or work plan. A scope of work should examine key project objectives, define present and future expectations, and identify studies analysis needed to met program objectives. The intent of the scope of work is to provide airport sponsor and local land use jurisdictions with useful and understandable information and guidance to develop a land use compatibility study that examines important information needed to develop strategies to protect airport facilities. A scope of work can also be an excellent tool for increased communication among stakeholders and provides a framework for community involvement. PROGRAM OVERVIEW
WSDOT Aviation -- Airport Land Use Compatibility Planning Program
Role of Airport Sponsors Role of Local Land Use Jurisdiction Joint Planning Responsibilities and Goals
Development of County-wide Policies Development of an Aviation Element within Metropolitan Planning Organizations and/or Regional Transportation Planning Organization (RTPO) documents Development of Comprehensive Plan Goals and Policies within affected jurisdiction Development of Consistent Compatible Land Use Development Regulations
DEVELOP CITIZEN PARTICIPATION PROGRAM
Identify key contact persons, aviation interest groups, public and neighbor organizations and other Establish a citizen advisory committee and/or technical advisory committee. Develop public meeting schedule for public information meetings, public workshops and public hearings to allow public review and comment Public meeting should begin early in the process.
Kick-off meeting to present and discuss background information, which may include planning process, purpose, historic data, existing land use information, airport characteristics, current conditions and so forth. Discussion of study analysis, recommendations and strategy alternatives. Review draft comprehensive plan goals, policies and consistent land use maps. Review of proposed implementation strategies and development regulations Final report recommendations, comprehensive plan goals and policies and implementing regulations. DEFINE STUDY AREA (Airport Influence Area)The study area is defined by overlaying the Federal Aviation Regulations (FAR) 14 CFR Part 77 “imaginary surfaces”, Aircraft Accident Safety Zone data and Noise Contour data over the top of an existing land use map, critical areas map or other base map. If possible information should be presented on a GIS-based map layers.
14 CFR Part 77 Imaginary SurfacesImaginary surfaces are defined in relation to the airport and to each runway. The size of these imaginary surfaces is based on the category of each runway for current and future airport operations. Any objects which penetrates these surfaces is considered an obstruction and affects navigable airspace.
Aircraft Accident Safety Zone DataThe accident safety zones represent data clusters of historical aircraft accidents. The data was collected from the National Transportation Safety Board (NRSB) and analyzed in several studies to first determine the shape of the zone based on the greatest cluster of accident sites per acre and second on the ratio of accidents per acre changes.
Noise Contour DataNoise contours represent noise levels generated from aircraft operations, takeoff and landing of aircraft. Noise contours are generated based on mythology developed by the Federal Aviation Administration. Noise contour data provides information that can be used to identify varying degrees of noise impacts on the surrounding area. Not every airport will have noise contour data and local jurisdictions should check with the airport sponsor on the availability of this information.
