AIRPORT COOPERATIVE RESEARCH PROGRAM Airports are vital national resources. They serve a key role in trans- portation of people and goods and in regional, national, and interna- tional commerce. They are where the nationâs aviation system connects with other modes of transportation and where federal responsibility for managing and regulating air traffic operations intersects with the role of state and local governments that own and operate most airports. Research is necessary to solve common operating problems, to adapt appropriate new technologies from other industries, and to introduce innovations into the airport industry. The Airport Cooperative Research Program (ACRP) serves as one of the principal means by which the airport industry can develop innovative near-term solutions to meet demands placed on it. The need for ACRP was identified in TRB Special Report 272: Airport Research Needs: Cooperative Solutions in 2003, based on a study spon- sored by the Federal Aviation Administration (FAA). ACRP carries out applied research on problems that are shared by airport operating agen- cies and not being adequately addressed by existing federal research programs. ACRP is modeled after the successful National Cooperative Highway Research Program (NCHRP) and Transit Cooperative Research Program (TCRP). ACRP undertakes research and other technical activi- ties in various airport subject areas, including design, construction, legal, maintenance, operations, safety, policy, planning, human resources, and administration. ACRP provides a forum where airport operators can cooperatively address common operational problems. ACRP was authorized in December 2003 as part of the Vision 100â Century of Aviation Reauthorization Act. The primary participants in the ACRP are (1) an independent governing board, the ACRP Oversight Committee (AOC), appointed by the Secretary of the U.S. Department of Transportation with representation from airport operating agencies, other stakeholders, and relevant industry organizations such as the Airports Council International-North America (ACI-NA), the American Associa- tion of Airport Executives (AAAE), the National Association of State Aviation Officials (NASAO), Airlines for America (A4A), and the Airport Consultants Council (ACC) as vital links to the airport community; (2) TRB as program manager and secretariat for the governing board; and (3) the FAA as program sponsor. In October 2005, the FAA executed a contract with the National Academy of Sciences formally initiating the program. ACRP benefits from the cooperation and participation of airport professionals, air carriers, shippers, state and local government officials, equipment and service suppliers, other airport users, and research organi- zations. Each of these participants has different interests and responsibili- ties, and each is an integral part of this cooperative research effort. Research problem statements for ACRP are solicited periodically but may be submitted to TRB by anyone at any time. It is the responsibility of the AOC to formulate the research program by identifying the highest priority projects and defining funding levels and expected products. Once selected, each ACRP project is assigned to an expert panel appointed by TRB. Panels include experienced practitioners and research specialists; heavy emphasis is placed on including airport professionals, the intended users of the research products. The panels prepare project statements (requests for proposals), select contractors, and provide technical guidance and counsel throughout the life of the project. The process for developing research problem statements and selecting research agencies has been used by TRB in managing coop- erative research programs since 1962. As in other TRB activities, ACRP project panels serve voluntarily without compensation. Primary emphasis is placed on disseminating ACRP results to the intended users of the research: airport operating agencies, service pro- viders, and academic institutions. ACRP produces a series of research reports for use by airport operators, local agencies, the FAA, and other interested parties; industry associations may arrange for workshops, training aids, field visits, webinars, and other activities to ensure that results are implemented by airport industry practitioners.

ACRP Research Report 174 defines and discusses green stormwater infrastructure (GSI) management strategies, a relatively new approach to regulation compliance. As more airports are proactively incorporating sustainable practices in all aspects of their operations, federal and state regulatory agencies are also promoting GSI strategies to comply with water regulations and requirements. There are some challenges in implementing GSI strategies, such as the perception that they are expensive and may conflict with safety and operational regulations, as well as a lack of understanding of what constitutes a GSI strategy, which includes techniques, technologies, and design elements. The Volume 1: Primer is written for the airport manager, planner, and engineer seeking to understand stormwater management and how GSI can comply with regulatory standards and requirements along with other benefits. Volume 2: Guidebook has been developed to assist airport staff with evaluating the applicability of a GSI strategy and how to select an appropriate GSI strategy. Stormwater regulations that affect all airports have evolved so that water quantity is as much a factor as water quality standards. Stormwater systems were designed to convey water runoff efficiently without regard to downstream impacts. Most people are familiar with these systems such as sewers composed of pipes and other mechanical equipment. Over time, stormwater regulations and requirements have progressed so that they are more encompass- ing and broad reaching. Concurrently, sustainability activities and techniques have become more mainstream within aviation and other industries. GSI strategies began to be imple- mented in the spirit of sustainability to meet stormwater requirements and strategies, though they are relatively new to the aviation sector. The Cadmus Group, under ACRP Project 02-62, was selected to develop (1) a primer to educate airport management on the benefits and applicability of incorporating GSI strategies into stormwater management programs and (2) a guidebook that identifies best management practices for GSI and a process to evaluate the appropriate strategies for implementation. The research was conducted in part by assessing GSI implementation at airports and the potential application at airports found in other industries. F O R E W O R D By Marci A.
