Brian Olson, P.E. - 10 - July 12, 2001 Residents south of the proposed development have expressed concern about an increase in cut- through traffic along Xkimo Street and Waco Street south of 153rd Avenue. Travel time runs were conducted in June 2001 to determine if using Waco Street or Xkimo Street is faster than TH 47. The results of the travel time runs are displayed in Table 4. Table 4 Travel Time Results Route Travel Time 153rd Avenue versus 149th Avenue Major: 153rd Avenue (at Waco street) to TH 47 (north o~ CSAH 5) 2:38 Cut-t .hrou. gl): Waco/X. kirno Street to 149th A..venue to TH 47 (north of CSAH 5) .. 2:58 153rd Avenue versus 142nd Avenue Majo_r: 153rd Avenue (at..Waco Street) to TH 47 (north o.f.C.S. AH 116) ... 3:57 Cut-through: Waco Street to t42nd Avenue to TH 47 (north of CSAH 1 I6) 3:58 I I I I I I, I' ! As shown in the table, it is approximately 20 seconds faster for development traffic to access TH 47 using I53rd Avenue instead of 149th Avenue. The results of the travel time runs also indicate that there is little difference in travel time'between accessing TH 47 at 153rd Avenue and using · waco Street to access TH 47 at 142nd Avenue. However, based on existing conditions, residents along 153rd Avenue are not using Waco Street as an alternate route to TH 47 to/from the south. This is shown by the low volume of vehicles turning off of and on to 153rd Avenue during the existing a.m. and p.m. peak hours. In addition, motorists tend to use an alternate route when the major route has significant congestion and delay. The intersection of TH. 47/153rd Avenue experiences minimal delay and operates at acceptable levels of service under existing and year 2006 conditions. Therefore, it is assumed that an insignificant number of trips generated by the proposed development will use Waco Street and Xkimo Street south of 153rd Avenue. Accesslssues There are six access points proposed for the development. Based on the roadway network and directional distribution, it is expected that the four main access points to/from the proposed development include Yakima Street at 156th Lane, 155th Lane at Barium Street, Xkimo Street at 153rd Avenue and Waco Street at 153rd Avenue. Ap, proximately 90 percent of the development trips will be evenly distributed amongst these four access locations. Table 5 displays the number of daily trips expected to use each of the six access points under full build conditions. -148- I I I I ! I I I, I I
