Home

subdivision consists of I28 urban single family homes on the property west of River's Bend and north of 149th Avenue N.W. Both parcels are east of State Highway ~o47. Mr. Boos stated that neighborhood park needs will be adequately met by existing park areas in the district (Woodland Green Park, Bear Park and River's Bend Park) if an adequate off-roadway avenue is available to reach the destinations. This off-roadway avenue would provide alternate transportation needs along State Highway #47 and would be a major trail to move people to lower density areas. Mr. Raatikka produced overheads illustrating the proposed trail corridor adjacent to State Highway 6{47 from north to south in Amber Ridge, within the north side of the 149th Lane N.W. right-of- way from State Highway #47 to Waco Street N.W., a trail from the southwest corner of Amber Ridge to 148th Avenue N.W., then easterly to the plat boundary, then north to t49th Lane N.W. (through back yards of homes on Yakima), then east to either Waco Street N.W. or the center of the preceding block, then north and east to Juniper Woods. A proposed berm above the trail surface would extend from the southern plat boundary to 149th Lane N.W. and separate State Highway g47 from the trail. The berm would have a continual planting of trees and seedlings. Mr. Raatikka indicated the cedars might be replanted on the berm. Parks/Utilities Coordinator Boos recommended preserving a trail corridor from 149th Lane N.W. north to the plat boundary. He added a'berm is not feasible in this area because of wetlands, but plantings there are very prudent. Discussion ensued regarding the slope of the trail, height of berm, maintenance, plantings, future corridors and tie-ins, controlled intersections, safety, and right-of ways. Parks/Utilities Coordinator Boos stated a berm of 7' in height adjacent to State Highway #47 from north to south in Amber Ridge would lessen noise impact and provide more wind protection than a lower berm. Mr. Boos also indicated that the 90 degree comer on the northern plat boundary may need to be adjusted. Parks/utilities Coordinator Boos explained the wetland at the southwest end of the corridor trail adjacent to State Highway g47 might eventually be crossed with a floating walkway or bridge. An estimate for a 30' bridge would cost less than $10,000. Currently, the City does not have access to the property. Mr. Raafikka indicated that it is the developer's intent to try to save as many trees in the subdivision as possible. Motion by Commissioner Swokowski and seconded by Commissioner Gooldn to recommend the the City Council adopt park dedication as follows: 1) 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. 2) Preserve a trail corridor adjacent to State Highway #47 from north to south in Amber Ridge. 3) Develop a bituminous sidewalk within the north side of the 149th Lane N.W. right-of-way from State Highway g-47 to Waco Street N.W. without the additional 10' purchased by the City leaving 2' between the trail and homeowners property. The monies gained by this deletion will be used to build approximately one quarter mile of trail possibly from Amber Ridge to 153rd Avenue N.W. 4) Develop a hard-surface trail from the southwest corner of Amber Ridge to 148th Avenue N.W., then easterly to the plat boundary, then north to 149th Lane N.W., then east to the Park and Recreation Commission/February 10, 1993 Page 2 of 3 ' I I I I I I I I I I I I I I I I
