f Proposed Improveinents Fcmdalc Road Reconstruction I • Fcmdalc Road is designated on the City's Municipal wState Aid Street System and is classified as a minor collector roadway. The function of a collector roadway is to collect traffic from local streets and connect to arterial roadways. This section of Femdale Road is presently in poor condition with significant surface distre.ss. Inadequate sight distances at some locations present safety concerns. The exi.sting street consists of a 6.7 meter (22 feet) wide bituminous .surface with 1 meter (3 feet) gravel shoulders. The drainage along the roadway is currently directed to shallow ditches. Femdale Road, as presented in this report, is proposed to l^e constmeted to a 9 ton design with B618 concrete curb and gutter. The urban design with curb and gutter provides a more efficient drainage .system, minimizes the need for additional right-of-way and significantly reduces tree removal. The north end of Femdale Road will be widened to provide a single southbound lane and two northbound lanes. The two northbound lanes will allow for east and westbound turning movements onto County Road 6. The hill north of Sixth Avenue will need to be lowered to meet a 30-mph design and improve sight distances. Also, a 3 meter (10 feet) wide bituminous walkway is proposed along the east side of the street from the Luce Line trail to County Road 6. The walkway will l->c graded south of the Luce Line trail to the Highway 12 bridge as part of the project. Future construction of the walkway south of tlie Luce Line trail will be the responsibility of Wayzata. The walkway would be located 1.5 meters behind the curb where topography and right-of-way permits. In areas where trees are to be preserved or embankments are steep the walkway will abut the back of curb. Pedestrian curb ramps will be required at all locations where the walkway intersects the street. A coticrete walkway was considered as an alternate pathway design as part of this report. The walkway would be 1.8 meters (6 feet) in width constructed of 100 mm (4 inches) of concrete and 100 mm (4 inches) of aggregate base. The walkway would be located 1.5 meters (4 feet) l>ehind the curb. The cost to constmet the concrete walkway is approximately 32 percent more than the co.st to construct the bituminous pathway. A detailed cost analysis for the concrete walkway an ’ ' c bituminous pathway are included in the Appendices of this report. As part of the street improvements, all existing driveways are proposed to be paved to match the exi.sting pavement Retaining walls, benns or hedges are proposed in some areas to preserve specimen trees and provide privacy for yards and houses close to the right of way. Where pra'^ tical, trees will be planted from nursery stock to replace those trees removed during construction. Plymouth Feasibility Report - Femdale Road Reconstraction
