located along the bay shore, along the Alameda County Flood Control Channel, or along <br /> existing rail lines owned by Southern Pacific Railroad or BART. More specific information <br /> must be developed as the actual parcels are identified and negotiations with the owners are <br /> conducted. The proposed system was designed to avoid the need to acquire additional right - <br /> of -way for Class II and Class III bikeways. <br /> Construction costs may be limited to signing for Class III bikeways and signing and striping <br /> for Class II bikeways. However, they could be more extensive improvements such as <br /> widening, restriping, or installing a signal or loop detectors. The proposed bikeway system in <br /> San Leandro was located on roads that, in many places, could accept Class II bike lanes, but <br /> would require changes to striping, lane widths, parking, and medians. Where traffic volumes <br /> are relatively low and the environment is conducive for bicycle riding, Class III routes were <br /> designated. As shown in Table 10, the average per -mile cost for a Class II bike lane is <br /> approximately $35,000, and the average per mile cost for a Class III bike route is $1,000, <br /> much less than the cost for Class II. These per -mile costs assume only basic constructions, <br /> not including special treatments such as signals, landscaping, br support facilities. <br /> The cost differential between Class II and III bikeways and Class I bike paths is substantial. <br /> The average per -mile cost for a Class I bike path in San Leandro is approximately $230,000 <br /> (Table 10), which can cover the costs to build about 6.5 miles of Class II bike lanes or 230 • <br /> miles of Class III bike routes. Conversely, Class I facilities tend to be longer routes serving as <br /> regional connectors and commuter routes. As a result, they compete more effectively for <br /> outside funding sources such as ISTEA. <br /> Based on these figures, the estimated base cost to implement the proposed bikeway system in <br /> San Leandro is $2,029,000. Table 11 provides a cost and funding breakdown for Phase 1 and <br /> 2 projects. <br /> Cost in Perspective <br /> The cost of the bikeway system may appear high when viewed as one lump sum, but in terms <br /> of cost effectiveness, it is a worthy investment.
