I I I Primary Zone - The first 1000 feet of the Clear Zone. Zone A - Area that is included in a circumference drawn from both ends of the runway with a radius equal to 2/3 the length of the runway. Zone B - Area that is included in a circumference drawn from both ends of the runway with a radius equal to the length of the runway. m m m m m m With regards to Clear Zones, Mr. Koshak stated that the owners of the airport must own the first 1000 feet or primary zone, by fee title. The second 1000 feet of property would have to have deed restrictions to it. Mr. Koshak stated that zoning would have to be addressed -- there would be a need for a zoning ordinance that would reflect the distance of the runway with a PadiuSj dealing with height limitations, density, etc. Mr. Koshak stated that Zone A would grandfather in existing buildings and limit future building. Zone B would have lesser restrictions. Commissioner Patz inquired if there is anything involved in upgrading the airport that could be considered impossible to accomplish. Mr. Koshak replied that a crosswind runway may be out at this time but the State is not pressing the issue. Commissioner Patz inquired as to building acquisition that would be required. m m Mr. Koshak replied that the first 1000 feet of clear zone (prin~ry zone) should be in fee title -- on the north end, with some shuffling of the airport configuration, we can eliminate or include certain properties. On the south end, it would not include Jimmy B's. In the second 1000 feet there is McGregors. The State Aeronautics Board will mandate How properties in the second 1000 feet are to be dealt with; there is a possibility they may allow the project to start with the understanding that eventually property in that area will be acquired. Commissioner Sieber inquired if there weren't allowances made for buildings with height restrictions. Mr. Koshak replied that the State Approach Slope ratio is 40 to I and the Federal Approach Slope ratio is 20 to I and this pertains to p~wer poles and T.V. antennas -- the State is restricting public use. Commissioner Sieber inquired if raising and lengthening the runway suggests that'~here are safety factors to be considered. Mr. Koshak replied that if the runway were raised an aircraft would meet minimum clearance requirements set for railroad tracks and displacing the threshold creates no problem. Commissioner Patz noted that these restrictions would not compromise safety, that Minnesota is known for it's outstanding planning of airports. Commissioner Greenberg pointed out that raising the runway at one end would actually level it, that there is about a 6 foot difference from one end to the other ri. ght now.
