4.Minor Revisions to the Draft Environmental Impact Report To mitigate the impacts created by Haul Route 3 on opening day,all-way stop control would be 6" reouired.However,all-way stop control should not be installed unless warrants are satisfied after the proposed project begins operating. Since Haul Route 3 is expected to be an interim altemate 60 route,it is unlikely that warrants for all-way stop control will be met on a long-tem basis. As an altemative to mitigating impacts at the intersection,the proposed project may be conditioned to operate at a maximum annual production of 1.33 million tons while Haul Route 3 is in operation. ` If the proposed project is limited to 1.33 million tons per year,the near-tem with-Project level of service will be C and no significant impacts will occur. To mitigate the cumulative 2025 impacts of Haul Route 3,all-way stop control will be required along with the construction of left-tum lanes on Welty Road and right-tum lanes on SR 33. As an altemative to mitigating cumulative year 2025 conditions,the proposed project may be �. conditioned to eliminate Haul Route 3 after the construction of the Bird Road/SR132 interchange, at which time only Haul Route 1 would be allowable. 11a. Additional analysis of the operating characteristics of the SR33/Welty Road intersection identified the following safety concems with Haul Route 3 through this intersection: .. Tuming Radius/Off Tracking Both double trailer aggregate trucks and tanker trucks were evaluated.The estimated wheel tracking pattems for both trucks taming right onto southbound Welty and northbound trucks turning left onto State Route 33 are shown in Figure 2 of the Peters Engineering memo dated May 28, 2008 (included in Appendix C of this FEIR) The double trailer truck has a more flexible taming radius than the tanker due to the intermediate hinge oint of the double aggregate trailers allowingfor or tighter tuming movements The analysis determined that the pavement was sufficient to allow for the truck tums at a speed of five miles per hour. The analysis also determined that the truck tires would extend to the edge of the existing pavements and would be required to cross over ` double yellow traffic stripes to make the turns. r Railroad Track Queuing The location of the limit line (stop bar)for northbound vehicles on Welty at State Route 33 relative to the railroad tracks allows for storage of one trek. Occurrences of more than one truck waiting to enter State Route 33 will create a queue ` which extends onto and which blocks the railroad tracks. Mitigation is provided below to minimize this hazard. ` Sight Distance Evaluation A site visit was performed on May 21, 2008 determined that the following horizontal sight distance constraints exist at the study intersection: Power poles in the southeast comer of the intersection block the visibility of northwest bound vehicles along State Route 33 for northbound vehicles on Welty attempting to enter the intersection. A tree approximately 230 feet southeast of Welty blocks the visibility of northwest bound vehicles along State Route 33 for northbound vehicles on Welty attempting to enter the r intersection.
