- curves, horizontal and vertical, have been designed to achieve a 45 mph design speed; some exceptions to vertical curve standards have been made to retain the ;." existing roadway and some curves will be "banked" to -- achieve the 45 mph design speed. - bike lanes are 6 ft. on-street, on both sides, meeting City and State standards. - the new sidewalk is separated (5 ft.), 8 ft. wide, meeting two-way pedestrian-bicycle path standards, except just north of Puri Court where it would be monolithic unless additional right-of-way is acquired. (Note: the sidewalk recently installed along Foothill Road does not meet normal bike lane standards because it is not separated at certain points of its "meander.") - center median curb treatment, although not ideal for maintaining "ruralness," is felt necessary to protect drivers and allow large trees to be established. In staff's opinion, the result will be a safe, attractive, "non- freeway roadway" in character. Tree loss unfortunately will be heavy in the area from Foothill Knolls Drive to Muirwood South; any widening here that would establish a turn lane and bike lanes would cause this tree loss. ALTERNATIVES Alternatives could be generated by adjusting one or more elements and recombining them into a new alternative. Because of the - Council's and Commission's expressed wishes to maintain a two-lane roadway for as long as possible, several "interim" alternatives are possible within the four-lane segment called for in the General Plan. Staff has developed alternatives for various sections of the roadway which Council may use to focus its attention on options available. These are shown in the attached figure "Foothill Road Alternatives - Typical Sections." Five alternatives are shown, including the recommended cross-sections. In addition, a different pedestrian path-bike path section is shownwhich could be used with any of the alternatives. The horizontal alignment of the staff- recommended interim alignments is also shown (pages 26-33 of the 11 x 17 packet of plans). What follows is a general discussion of alternatives to the street elements recommended by staff, with the reasons for staff's recommendation. Following this general discussion is a summary of the benefits and detriments of the specific staff-developed alternatives. Travel Lane Widths The various lanes can be narrower. The lane adjacent to the median could be 12 feet (used elsewhere in the City, eg. Stoneridge Drive east of Foothill, Foothill Road north of Stoneridge). Travel lanes could be as little as 11 ft. Staff opted for standard widths SR91:52 10
