ADDENDUM DETERMINE PARK DEDICATION FOR AMBER RIDGE By: Mark Boos, Parks/Utilities Coordinators Case #2 Observation's: The gross area of Amber Ridge, less State Highway 047 and 149th Lane N.W., is 56.31 acres, requiring a minimum of 5.63 acres of land or equivalent in land and cash value. Neighborhood park needs will be adequately met by existing park areas in the district if an adequate off-roadway avenue is available to reach the destinations. Development of vacant land north of Amber Ridge and lot splits resulting from eventual extension of municipal services will exacerbate any pedestrian traffic hazards in the area, increasing the need for north/south alternative transportation. The behemoth cottonwood trees and the wetlands are the only significant natural features in the proposed subdivision. (For many years each spring, these cottonwoods have been a nesting location for a pair of red tailed hawks.) State Highway #47 is a high impact road. A trail corridor adjacent to the roadway will remove bicyclist's from it and provide a buffer to the residentiaI housing. However, adequate protection, visual, physical and aesthetic, should separate trail users from the State Highway. A landscaped berm, substantial in height, would accommodate this and be a benefit to the nearest homes. Recommendations: All larger stature trees should be accommodated and protected in the development of Amber Ridge. All moveable trees of value that are in the path of destruction should be relocated for trail screening and delineation. Preserve a trail corridor adjacent to State Highway 047 from north to south in Amber Ridge. Develop as a Stage I improvement, an 8' hard-surface sidewalk within the north side of the 149th Lane N.W. right-of-way from State Highway 047 to Waco Street N.W. Develop as a Stage"t4 improvement an 8' hard-surface trail from the southwest comer of Amber Ridge to 148th Avenue N.W., then easterly to the plat boundary, then north to 149th Lane N.W., then east to either Waco Street N.W. or the center of the preceeding block, then north and east to Juniper Woods. Park dedication credit will be given for all areas dedicated for trail purposes outside of and,exc.l, usive of, street right-of-way. A berm, minimum of 7' in height above the trail surface, should extend from the southern plat boundary to 149th Lane N.W. and separate State Highway g47 from the trail. The berm should be entirely planted and staked with seedling trees and shrubs. If possible a berm should also extend from 149th Lane N.W. north to the plat boundary. This transition, whether bermed or not, should also be forested. The developer will also be required to submit a landscape plan for the area adjoining the sidewalks and trail.
