using stormwater modeling. If needed, structural pollution control devices and/or surface treatment improvements such as infiltration basins or trenches will be constructed. The engineer for the Lower Rum River Watershed Management Organization will be consulted to determine whether infiltration practices will be required with this project. 4.1.2 164th Lane 164th Lane is proposed to be reconstructed with bituminous pavement and B618 concrete curb and gutter to provide better drainage and allow for more cost-effective street maintenance operations over time. Numerous streets throughout the City utilized bituminous curbs when they were constructed. These streets appear to be deteriorating more rapidly than streets with concrete curb and gutter due to their reduced ability to effectively drain stormwater from pavement, and because concrete curb and gutter protects pavement edges better. The scope of the proposed surface improvements is shown in Figure 1 in Appendix A. On -Street Bike Lane: An on -street bike lane was recommended to be constructed with this project by the Public Works Committee as a compromise to installing off-street concrete sidewalk which was overwhelmingly opposed by residents in 2008/09 resulting in a petition that stopped the project from being constructed. The on -street bike lane is proposed to be 6 feet wide and located along the east and north sides of Andrie Street and 164th Lane. The east and north sides were chosen because more side street connections exist on these sides of the streets which would prevent pedestrians wanting to use the bike lanes from needing to cross Andrie Street or 164th Lane at each of the side streets. In addition, the north and east sides of streets receive more sunlight so any ice, snow or water on the bike lanes will evaporate faster. An on -street bike lane would also provide a dedicated pedestrian connection between the existing 10 -foot wide bituminous trail along the north side of Alpine Drive to the on - street pedestrian facilities along Jarvis Street. Street Design: As proposed, approximately 65% of Andrie Street and 164th Lane are proposed to be reconstructed at their existing widths. The remaining 35% of these streets are proposed to be reconstructed to allow for on -street parking using a width of 38 -feet from face -of - curb to face -of -curb. Typical sections for the proposed design are shown in Figures 2 and 3 in Appendix A. A typical section for the alternate design is also included in Figure 4 in Appendix A. The proposed pavement design must accommodate a 9 -ton design in accordance with State Aid design standards. City staff proposes a pavement section of 6" modified class 5 aggregate base, 2" bituminous base course, and 11/2" bituminous wear course. This design assumes less than 150 heavy commercial vehicles travel on these streets daily, which Feasibility Report Andrie Street and 164th Lane Reconstruction City of Ramsey Project No. 16-00 Division C Page 9
