LACONIA MUNICIPAL AIRPORT APPROACH PLAN
(Amended)
Adopted by New Hampshire Aeronautics Commission
January 9, 1967
(This is included herein for reference only and is not a part of the Gilford Zoning Ordinance.)
1. This Airport Approach Plan, prepared under the authority of Chapter 424.3 of the New Hampshire Revised Statutes Annotated, is based upon the ultimate development of an Express Type Airport with runways and landing strips as follows:
(a) Runway 8-26, instrument runway 5,900 ft. by 150 ft.; landing strip 6,300 ft. by 500 ft.
(b) Runway 17-35, 3,500 ft. by 150 ft.; landing strip 3,500 ft. by 500 ft.
2. Civil Aeronautics Administration TSO-N18 dated April 26, 1950, “Criteria for Determining Obstructions to Air Navigation” establishes the standards used to determine the limit of height of obstructions in the vicinity of the airport.
3. The limit of height of obstructions shall be:
(a) In the approach areas to Runway 8-26 which are 1,000 ft. wide at a point 200 ft. from the end of the pavement and 4,000 ft. wide at 10,200 ft. from the end of the pavement, an inclined plane of 50:1 slope and for an additional 40,000 ft. at which point it is 16,000 ft. wide, an inclined plane of 40:1 slope.
(b) In the approach areas to Runway 17-35 which are 500 ft. wide at a point 200 ft. from the end of the pavement and 2,500 ft. wide at a point 10,200 from the end of the pavement, an inclined plane of 40:1 slope.
(c) On the sides of the landing strips and approach areas, an inclined plane of 7:1 slope.
(d) 702 ft. above sea level within 8,500 ft. of the Airport Reference Point. (150 ft. above the airport)
(e) Between 8,500 ft. and 13,500 ft. from the airport a line with a slope of 20:1 measured in a vertical plane passing through the center of the airport.
4. No provision of Section 3 shall limit the height of a structure or tree to less than 30 ft. above the ground upon which it is located.
5. The Airport Reference Point is the intersection of the perpendicular bisector of the runways.
Note: The following is for information only and is not a part of the Airport Approach Plan:
1. The building line for Runway 8-26 is 750 ft. from centerline. The building line from Runway 17-35 is 425 ft. from centerline.
2. Acquisition of property rights will be necessary: (a) to remove existing obstructions; (b) to control the height of objects in those areas where the controlling inclined plane is less than 30 ft. above the ground.
