Description: From Texas Airports, approximate RPZ calculated for largest aircraft type according to FAA guidance. These are military airfield Accident Potential Zones (APZ) and civil airport Runway Protection Zones/Clear Zones (RPZ/CZ) in Harris County, Texas. These trapazoids were sketched using FAA guidelines first proposed by General Jimmy Doolittle after World War II. They are used to visualize APZ and RPZ/CZ for HUD Part 58 environmental review Airport Hazards element.Accident Potential Zone (APZ)Does your project involve any of the following: new construction; substantial rehabilitation; acquisition of undeveloped land; activities that would significantly prolong the physical or economic life of existing facilities or change the use of the facility to a use that is not consistent with the recommendations of the Department of Defense (DOD)’s Land Use Compatibility Guidelines; activities that would significantly increase the density or number of people at the site; or activities that would introduce explosive, flammable, or toxic materials to the area? If so, is the project in conformance with DOD guidelines?Runway Protection Zone/Clear Zone (RPZ/CZ)Will this project involve any facilities that will be frequently used or occupied by people?If so, were written assurances from the airport operator obtained?If this project involves the acquisition or sale of an existing property that will be frequently used or occupied by people, you must provide written notice to the prospective buyer to inform them of the potential hazards from airplane accidents as well as the potential for the property to be purchased as part of an airport expansion project in accordance with 24 CFR 51.303(a)(3). (See Sample Notice to Prospective Buyers.) The written notice should inform the prospective property buyer of: (i) the potential hazards from airplane accidents, which are more likely to occur within clear zones than in other areas around the airport/airfield; and (ii) the potential acquisition by airport or airfield operators, who may wish to purchase the property at some point in the future as part of a clear zone acquisition program.HUD assistance may not be used at this location if project involves new construction, substantial rehabilitation, acquisition of undeveloped land, or activities that would significantly prolong the physical or economic life of existing facilities that will be frequently used or occupied by people.
