1 1 ' Q: Would adequate traffic operations be provided at the following intersections upon full completion of the proposed development? 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 • CSAH 14 /CSAH 23 • CSAH 14/4`h Avenue North • CSAH 23 /Pine Street • CSAH 14 /development access • Pine Street /development access To address this question, AM and PM peak hour capacity analyses, using the Highway Capacity Software (HCS), were completed for the 2006 Existing, 2011 No- Build, and 2011 Build scenarios. Analyses for the 2011 build scenario were completed using the geometry described in the Existing Conditions section. In addition, the geometry used in the analyses for the proposed access to CSAH 14 consists of one left -right turn lane on the north approach, one through lane and one right turn lane on the east approach, and one through -left turn lane on the west approach. The geometry used in the analyses for the proposed access to Pines Street consists of a left -right turn lane on the south approach, a through -left turn lane on the east approach, and a through -right turn lane on the west approach. Capacity analysis results are presented in terms of level of service (LOS), which ranges from A to F. LOS A represents the best intersection operation, with very little delay for each vehicle using the intersection. LOS F represents the worst intersection operation with excessive delay. Results of the capacity analyses are presented in Table 2 and Table 3. Table 2 Weekday A.M.
