M E M 0 RAN DUM September 9, 1985 __ TO: Eugene Mayor and City Council FROM: Planning Department on Behalf of the Planning Commission SUBJ: PROPOSED COMMERCIAL AIRPORT SAFETY SUBDISTRICT Background. As part of their comprehensive planning program acknowledgement request, in 1984 the Lane County Board of Commissioners adopted an Airport Safety Combining District based on the provisions of Part 77, Federal Aviation Requirements. The City encouraged the County to include this item in its comprehensive planning and zoning program consistent with Policy #15 on page III-F-6 of the Metropolitan Plan which reads: The City of Eugene and Lane County shall adopt up-to-date airport safety ordinances which regulate the height of structures, electromagnetic and/or visual interference with aircraft, and other hazards to airport safety. Based on the County-adopted ordinance, the Eugene Planning Commission held a public hearing and unanimously recommended a similar amendment to the City1s Zoning Ordinance on April 9, 1984. The delay since the Commission1s action results from a technical error in the County1s ordinance that needed to be corrected before you Gould consider adoption. That error has now been remedied. ~ Subdistrict Description. The subdistrict has' two main purposes: 1. To prevent obstructions that could be a hazard to air navigation and flights. Structures that penetrate the surfaces described in the zoning text and illustrated on an accompanying map are to be identified with markers and lights installed, operated, and maintained by ~he City. 2. To prevent other hazards to air navigation and flight from occuring within the bounds or the described surfaces such as distracting light and gl are produci ng surfaces, radi 0 interference, smoke, steam or dust, areas which attract birds, and hazards of a similar nature. The subdistrict would only affect those few areas that are within the City1s limits and under the described surfaces. (See the map and draft ordinance language attached under separate cover.) The proposed text closely parallels the County version. The map surfaces and extent are identical to the County version. The text does not include a list of permitted uses. That is lert to the parent districts that remain in place. Rather, it includes perrormance standards regarding (1) structural height, (2) electrical interference with navigational aids and radio communication between the airport and aircraft, and (3) visibility impairment that might endanger landing, take off, or maneuvering of aircraft. Its impact on existing and future uses within the City sh.9uld not cause undue h,ar?ships to private businesses and other land . uses. ror example, structure ne1ghts would have to be 150 to 250 feet above _ the ground to penetrate the app] icable surfaces in t.he Bethel Neighbornood ,.
