6/24/75 AC 150/5300-4B <br />CHAPTER 6. SITE INVESTIGATION <br />23. GENERAL. There are many factors which must be considered in selecting <br />an airport site. These factors include such things as accessibility <br />to the users; Government regulations affecting airport development; <br />ease with which the site can be developed; the existence of obstacles <br />that might interfere with aeronautical operations; the occurrence of <br />conditions of reduced visibility (fog, smoke, etc.); the effect of the <br />development on the surrounding environment; and the feasibility of <br />future expansion and instrument operations. Advisory Circular <br />150/5070-6, Airport Master Plans, discusses in detail the subject of <br />airport selection. The primary purpose of this chapter is to briefly <br />present the Government regulations that must be considered and the <br />engineering factors that must be analyzed in reviewing potential sites <br />for a utility airport. <br />24: GOVERNMENT REGULATIONS. <br />a. Federal Aviation Regulations Part 157, Notice of Construction, <br />Alteration, Activation, and Deactivation of Airports, requires that <br />the FAA Airports District Office or regional office be notified by <br />persons proposing to construct, alter, activate, or deactivate a <br />civil airport. The FAA will conduct an aeronautical study to <br />determine the effect of the proposal on the safe and efficient use <br />of airspace. Upon completion of the study, the proponent will be <br />notified of the FAA's determination. Advisory Circular 70-2, <br />Airspace Utilization Considerations in the Proposed Construction, <br />Alteration, Activation and Deactivation of Airports, discusses in <br />detail this FAR Part 157 requirement. This advisory circular also <br />contains the addresses and geographic jurisdictions of the FAA <br />offices. These offices should also be contacted to determine the <br />requirements which must be met if it is desired to develop the <br />airport with Federal funds. <br />b. In addition, most states require their approval of the proposed air- <br />port through licensing or some similar means.' The state in which <br />the proposed airport will be located should be contacted directly <br />to determine that state's requirements. <br />c. The local governing body should also be contacted to determine if <br />they have any laws that may affect the proposed airport. <br />25. ENGINEERING ASPECTS OF SITE INVESTIGATION. An investigation of all <br />potential sites must be made for two purposes: to determine an esti- <br />mated cost of development, and to allow a comparative analysis of all <br />potential sites. The services of an experienced engineer should be <br />enlisted since the investigation will require a thorough knowledge of <br />engineering principles and practices. The factors that should be <br />analyzed in selecting an airport site are presented in the following <br />paragraphs. For convenience, a checklist for the required engineering <br />information is included in Appendix 2 of this publication. <br />Chap 6 <br />Par 23 <br />Page 25 <br />
