e e Cindy Sherman January 13, 1999 Page 6 . Communities without any [public-owned] aviation facility within its area [RAMSEY] (protect general airspace); . Communities partially within an airport zoning district (protect general airspace plus the airspace immediately surrounding a nearby airport(s)); and, . Communities within which an airport is located (protect general airspace plus the airspace immediately surrounding the airport within the City limits). All communities, with or without any aviation facility within its jurisdiction are affected by requirements to protect the region's general airspace. Under Minnesota Statutes 360, the state regulates the height of structures; and, and they are defined and enforced under Aeronautics Rules and Regulations 8800.1200 Criteria for Determining Air Navigation Obstructions. Subparagraph 4 identifies general airspace obstructions; item B states " objects more than 200 feet above the ground or more than 200 feet above the established airport elevation, whichever gives the higher elevation, within three nautical miles of the nearest runway of an airport, and increasing in height in the proportion of 100 feet for each additional nautical mile of distance from the airport but not exceeding 500 feet above ground", is a general obstruction. All communities affected by general airspace should include local codes/ordinances to control the height of structures, especially when conditional use permits would apply. The comprehensive plan should include policy/text on notification to MnDOT, as follows: Notification: Any sponsor who proposes any construction or alteration that would exceed a height of 200 feet above ground level at the site, or any construction or alteration of greater height than an imaginary surface extending upward and outward at a slope of 100: 1 from the nearest point of the nearest runway of a public airport shall notify the Commissioner at least 30 days in advance. This local reporting is in addition to the Federal permitting/review process involving a sponsor/proposal where FAA Form 7460-8 submittal is required. B. Recreation Open Space - (Phyllis Hanson, 651-6021566) This section addresses issues regarding the impact of the plan on parks and other open space. A review of the plan indicates that the plan is complete for review in this area, but the following advisory comments are offered for your information: Regional Recreation Open Space facilities in Ramsey include the underdeveloped Mississippi West Regional Park, Rum River Central Regional Park (currently being developed), and the Anoka County Mississippi River (county boundary to the city of Anoka) Regional Trail. The Metropolitan Council has approved master plans for the regional parks, but not the proposed regional trail. Ramsey and Anoka County Parks Department are encouraged to continue cooperating in the planning of the regional trail for Metropolitan Council review and approval. As a minor comment, the park and trail plan should show appropriate classifications of the elements and indication of the trail and park types in the key. Of particular note would be the noting of the three regional facilities as regional.
