The need for left turn lanes on Shields is more based on an interruption of through traffic or accident history than by volume. Unless this was provided by the Developer or the City it is unlikely that the improvements would be made in the near future. The LOS A rating for through traffic on Shields indicates that the through traffic is not being significantly impaired or delayed by the turning vehicles at this intersection. The safety issues of an increasing volume of left turns from Shields could be partially mitigated by reducing the speed limit on Shields to reduce the differential speeds of through and turning vehicles. 4. For purposes of determining the amount of impact the development will have on this area it would be informative if the background only conditions were run. This would permit the identification of significant impacts due primarily to the new development as opposed to impacts caused by the anticipated background traffic volumes. 5. The background traffic volumes should include some effect of the McKee Trust to the south. It is not clear if this was the case or not. Thank you for the opportunity to comment on this proposal.

Director of Engineering Elaine W. Spencer This development will add significant traffic to Shields and Trilby in this area. Traffic is increasing on both roadways and particular attention needs to be paid to the Trilby/Shields intersection and to Shields Street north of Trilby to Clarendon Hills. Shields Street north of this proposal does not meet current urban standards and should be improved. The intersection should be signalized with this development if it meets warrants. Larimer County is not in a position to signalize this intersection unless funds are made available through the North Front Range Transportation and Air Quality Planning Council (NFRT&AQPC). Construction drawings for improvements to Shields and Trilby should be submitted to this office for review. The following items relate specifically to the traffic report. Any questions regarding these comments should be addressed to Brian Fraaken at 498-5718. 1. In reviewing the existing count data with the future background traffic volumes it appears that there are .several questionable future background traffic volumes. Specifically, the northbound AM right turns from Shields to Trilby decrease from 1995 to 2000, and no growth in background traffic (1995 vs 2015) is shown for the AM eastbound left turns as well as PM northbound left turns and southbound right turns. It is unlikely that there will be no growth (or decrease) in any background turning movement volumes at this intersection. 2. In reviewing the site traffic at the intersection of Shields and Trilby it is evident that there are several errors in routing the site traffic volumes through the intersection from/to the site accesses. These errors are up to 70 vehicles in the peak hour (for instance the site traffic entering the intersection for the Short Range Afternoon Peak Hour Traffic from the south is 70 vehicles less than the sum of the site traffic routed through the North Road access point). Due to the large number of these errors and the potential for them to affect critical movements through the intersection the results shown in the intersection analyses may not be valid. Site traffic in 2015 is shown as static or decreasing from 2000 on the AM peak southbound right turn and the westbound through movements as well as the PM peak southbound right turn and eastbound left turns. As the site traffic volumes are to increase significantly from 2000 to 2015 it is not likely these turning movements would not increase too. t BOARD OF COUNTY COMMISSIONERS John Clarke Janet Duvall Jim Disney District I District 11 District III PROJECT COMMENT SHEET DATE: 28 June 1995 DEPARTMENT: PROJECT: Registry Ridge PUD PLANNER: Engineering All comments must be received by: Wednesday July 12, 1995 ❑ No Problems 0 Problems or Concerns (see below) 6zc a i4zle ller Date• "7/iV /9.5 Signature: 4't�r X6• "cam CHECK IF YOU WISH TO RECEIVE ❑ PLAT COPIES OF REVISIONS: ❑ SITE P!T4 .fir n7wr-wf� �v % ) -_7 ❑ LANDSCAPE oy c5tuajo ❑ UTILITY COMMUNITY PLANNING ENVIRONMENTAL SERVICES • 281 NORTH COLLEGE P.O.BOX 580 FORT COLLINS, COLORADO 80522-0580 (303)221-6750 CURRENT PLANNING DEPARTMENT
