aircraft ~i l 1979-1980; the lowest number of based aircraft was 12-14 a couple o~ ~ea~s ago. The existing facility lies on the easterly portion of 1200 acre~ of!industrial property; to the north is residential development; the 1. and~[1 is to the northeast; urban residential development is to the east, a~ l~m~erical property to the south along Hwy. ~10. From a land use compatibil!itylstandpoint, the type of facility planned looks good except for the !&~df~l. Landfills are generally regarded as incompatible with airports~ '.iTh~existing facility has 2 landing strips with the primary runway ih ~ n~.rthwest/southeast direction and the crosswind runway in a east/wes~ ~ir.~.ction. The crosswind runway would be abandoned. It is proposed!fPr ~he facility to have a 3300' basic utility paved runway that would se~ s~.ngle and light twin engine aircraft under 12,000 pounds in weight, iT~e ~oposal would require relocation of County Rd. #116, airport building ~.~fea iimprovements and obstruction removals (trees, power lines). There are ,~wolaspects to airport zoning -- height limitations and land use safety zgn~ng~ Height and land use zoning results in an ordinance geared towards p~bte~ting property, people, aircraft and businesses close to airports~ i Th~re are several advantages to adopting airport zoning, one of which is ~t~at iit would prohibit certain types of uses incompatible with airports iahd ~ertain development from occuring. This particular hearing is the firs~ .pf ~o to be held on the proposed zoning ordinance. This hearing is to pres~nt .f the basics of what is contained in the ordinance and receive commentsi !There will be a 10 day period following the hearing in which written ~ts regarding the ordinance will be received. Those comments will be ~.~ ~i~ered and appropriate revisions to the ordinance will be made. The ordi~a~ :etwould then be resubmitted to the City and MN/DoT Aeronautics D~v~slo~ ~or, review. Upon approval by the Aeronautics D~v~s~on C°mmissi~r,IC°uncil9 will set a second public hearing date. At that second h~ea ~ing, the City will present the final ordinance draft intended for adop~i 3n. i If no further changes are made to the ordinance at that hearing, it ~e ~ity can adopt the ordinance. If there are changes resulting from the ~ec~nd hearing, the ordinance would be sent back to MN DoT Aeronautic Division for another approval prior to City adoption of it. Mr. Otto p~OCeeded to explain height limitations which are best described as imagi~a~ ~urfaces in a bowl-like configuration. The primary zone is a surface ex~end~ing 200' feet beyond the ends of the runway and 250' frcm the centerlinel of {the runway on each side; no elevation in that primary surface will be h~gh~r than the runway. From that primary zone extends the approach ~one surface which inclines upward at a slope of 40:1. The horizontal~izo~e is all that land which lies directly under an imaginary horizontal s~rface 150' above the airport elevation or 1020' and encompasses an area 6200' from the ends of the runway pavement. The conical Z~ne !is that surface extending upward and outward from the horizonta~i-su~face at a slope of 20:1 for a distance of 4,000 feet. The transitib~al izone is that surface extending upward and outward at a slope of 7,:l~Ifrom the sides of the primary and approach surfaces. GenerallY, l!a 1!50' height restriction is not a major concern of residents. Height l~itations impact radio towers, t.v. antennas, water towers, landfills, iet¢. The most significant restrictions to residents occur closer inl ~o ~he approaches which rise at a slope of 40:1; 2000' from runwaynend !ithelre would be a 50 ' height restriction, etc. Airport Zoning Board/March 11, 1987 Page 2 of 12
