Design considerations such as placing subdivision street lighting near trail entrances or road crossings should be ~ employed. Trail lighting, however, should be used only when necessary to minimize operating Costs. The City uses two standard minimum trail corridor widths of 35-feet in the urban area and 75-feet outside the urbaniz&t area. The wider width allows for the opportunity to develop two separate treadways. One co,fisisting of either a mowed surface, woodchips, or crushed rock to be used by cross country skier, s, horses, joggers, and mountain bikes. The other, an eight or ten-foot bituminous surface 0esignated for pedestrians, bicyclists and wheeled skaters. Both widths of trail corridor shall conta!n the paved bikeway/walkway. The narrower urban width of 35' maximizes the developable lan~l in the urban area. Along urban trail corridors, consideration should be given for picnic nodes o4 other types of rest areas which also provide deviation in the narrow width. Both corridor widttis should be considered minimum to provide adequate buffeting, green space and public control ~ the aesthetics. The City should ma~c~ e an effort to ensure all trails are barrier-free. Trail elevation shall not be more than 5% in grade br areas that exceed 5% shall have limited alternate travel routes such as residential streets. ~ntry and exit ramps connecting the paths to the roadways may be 8% in grade. £ Areas exceeding 5% must be identified. All hard surface tr~ails should be designed for routine travel by maintenance vehicles and patrol cars. Signage shod'ld be used to exclude unauthorized motorized vehicles. In problematic areas, gates or posts may be needed. In these cases, break-away posts or locking gates should be considered to provide access for police, fire and ambulance.
