(4) Assumes 2.0'deck thickness maximum for bridge 2. Design Calculations a. Station Capacity The design waste transfer capacity of the Station is approximately 1,320 TPD as presented previously in Section I. . .a..The total Station capacity will also include additional amounts from recycled material. ® b. Traffic Loading • Traffic projections for the Station were previously presented in Section I.E. A key concern of traffic control is processing and stacking of the Non-Automated Disposal traffic on peak weekend usage. This has been a problem at the Station in the past with the current limited entry lanes. In order to provide baseline data to model projected stacking of traffic in the two P P J g proposed new Non-Automated Disposal entry lanes, the CSWD compiled reports of hourly traffic for selected weekends in 1992 and early 1993 (back of Appendix B). Appendix B contains stacking calculations [Table III-D-4 from Non-Automated Disposal traffic taken from records for August 22, 1992 (chosen as highest from record on weekends from 8/92, 12/92 and 1/93)] for queuing of Non-Automated Disposal traffic during peaks. In order to model future conditions, the August 22, 1992 data is increased, in calculation rows, by 5 percentage point increments up to 80%. The increase of approximately 80% over the peak August 22, 1992 data corresponds to the expected traffic increase in the year 2010 (83.64% over 1992; See Table I.E. High). Two calculation sheets are shown on Table III.D.4.,indicating the gate stacking under constant processing rates of both 45 and 30 seconds per customer. According to County time studies; 45 seconds per vehicle was the approximate processing time in 1992. Time studies by the County with the new Station computer system ranged down to 30 seconds per transaction. The calculations appear to indicate that stacking will exceed available stacking space on the station entry road (of roughly 45 spaces), under the 45 second process rate, at 50% above August 22, 1992 numbers. These conditions are highlighted on the Table (numbers in excess of 45). At a 30 second processing rate, stacking on to the Roadway should not occur up to 8 % above the August 22, 1992 data. It should be noted that increasing the August 22, 1992 data showed that stacking onto Lovelace Road would become exacerbated after a peak, is experienced (even though incoming trips may be decreasing) because the stacked traffic overlaps hourly quantities. The analysis appears to indicate that staging provided in the new entry 07549001.012 26 September 23,1993
