APPENDIX A: TRANSPORTATION FEE NEXUS ANALYSIS AND METHODOLOGY Nexus Analysis In order to include these capital projects in the TIF program, it is necessary to establish a "nexus" or relationship between new development in Pleasanton, the need for transportation improvements in order to serve that new development, and the cost of the improvements that would be covered by the TIF. The following procedures have been used to evaluate that nexus relationship. First, there has been an evaluation of whether there is an existing deficiency at any of the project locations, and if so, the magnitude of that deficiency. Existing deficiencies are accounted for by reducing the project cost that is included in the fee program. Second, there has been an evaluation of the proportion of the remaining project cost that is attributable to development in Pleasanton, and therefore could be the subject of a fee program. Analysis Methods The operations of roadway facilities are described with the term level of service (a qualitative description of traffic flow based on factors of speed, travel time, delay, and freedom to maneuver). Six levels are defined from LOS A, as free-flow operating conditions, to LOS F, or over-capacity operating conditions. LOS E represents "at-capacity" operations. When traffic volumes exceed intersection capacity, stop-and-go conditions result, and operations are designated as LOS F. Signalized Intersections The level of service method identified by the City of Pleasanton General Plan for signalized intersections is the method described in the 2000 Highway Capacity Manual (HCM 2000) (Transportation Research Board). This method calculates signalized intersection operations based on the average vehicular control delay. Control delay includes initial deceleration delay, queue move-up time, stopped delay, and acceleration delay. The average control delay for signalized intersections is calculated using computerized analysis software and is correlated to a LOS designation as shown in Table A-1. The City of Pleasanton General Plan applies LOS D as the performance standard at most intersections. Economic&Planning Systems, Inc.
