CDOT has reviewed the Transportation Impact Study for the New Creation Church Preschool dated November 23, 2013 by Kimley-Horn and Associates. Once CDOT receives the Permittee’s comments addressing our concerns, we will finish our review. Review Comments: 1. The Permittee owns two adjacent parcels: 2123-352-00-098 and 2123-352-00-099. The report needs to clarify if the preschool and its traffic circulation areas will be on the same parcel as the church. Varying conditions will apply depending on whether the church and the preschool are on the same or separate properties. 2. Trip Generation: Use the Peak Hour of Generator (a.m. and p.m.) rates; cf.: SHAC §2.3(4)(d), The analytical approach shall include the highest peak hour volume within the entire day for each turning movement. 3. Trip distribution: Additional justification will be needed on the trip distribution. The trip distribution cannot be totally based on the current student residence location. With the preschool relocating to the west there will be greater out-of-direction travel for those living in Glenwood Springs; 20 to 30 minutes round trip. Therefore it can be expected that the percent to and from the east will drop and the percent to and from the west will increase. 4. The weekday traffic to and from the church offices needs to be included in the driveway volumes. 5. A growth factor needs to be applied to the CR 138 traffic and the driveway traffic. Those growth factors do not have to be the same as for the highway nor the same as each other. Unless the church is currently at capacity, the ITE rates will probably apply for the long-term volume for the church traffic. The volumes in the 2003 permits for CR 138 and the driveway were 32 vph and 40 vph, respectively, or a combined volume of 72 vph. The current combined volume is 183 vph (Figure 4). 6. The report does not state the number of days per week the preschool will be opened. If it will be opened on Sundays that volume will need to be included in the Sunday projections. If not, that will need to a condition of the permit. 7. The waiving of the turn lane requirements because of the highway volumes is not automatic. A design waiver request will need to be submitted (Form 112). 8. It appears that the left-turn deceleration lane might not qualify for a waiver. The projected opposing traffic volume is 98 vph (Figure 6). The adjustments discussed above may push that volume above the Page 2 of 2 100 vph threshold. Both the through and the right-turning traffic is counted as opposing traffic since the left-turning traffic will need to wait for both. 9. The report needs to show the conversion to Passenger Car Equivalent traffic volumes. We prefer that the raw traffic counts are listed in a table and show the conversion to PCE in the same table. All traffic volume figures should be shown as PCE volumes and so noted on the figure. The street view in Google Maps shows two buses parked at the church. 10. Figure 6: The title says “Sunday” but the legend says “Weekday”. 11. Figure 7, et.al.: The title says “New Creation Church” but the data is for “New Creation Preschool”. 12. In addition to addressing the warrants in the Access Code, the report needs to include the consultant’s recommendation to construct or not to construct auxiliary lanes as safety improvements. 13. Include a recommendation for the design vehicle to be used for the design of the NTP plans. Once we receive your comments addressing our concerns we will begin our 45 day review process. If I can be of any further assistance please call.

Sixth St., Room 100 Grand Junction, Colorado 81501 Re:Proposed New Creation Church Preschool Level Two Traffic Study – Access Permit Request US-6 and County Road 138, New Castle, Colorado Traffic Comment Response Letter Dear Mr. Roussin: Thank you for your comment letter dated February 4, 2014 for the New Creation Church project traffic study prepared by Kimley-Horn and Associates, Inc. dated November 23, 2013. This letter has been prepared as a response to your comments as written in your review letter. Comment/Question 1.The Permittee owns two adjacent parcels: 2123-352-00-098 and 2123-352-00-099. The report needs to clarify if the preschool and its traffic circulation areas will be on the same parcel as the church. Varying conditions will apply depending on whether the church and the preschool are on the same or separate properties. Response The preschool will be on the same parcel as the church. Comment/Question 2.Trip Generation: Use the Peak Hour of Generator (a.m. and p.m.) rates; cf.: SHAC §2.3(4)(d), The analytical approach shall include the highest peak hour volume within the entire day for each turning movement. Response We concur, since this is only a Level II Auxiliary Turn Lane Assessment for this project, use of the peak hour of the generator rates is applicable. The traffic study was revised with this trip generation. Comment/Question 3.Trip distribution: Additional justification will be needed on the trip distribution. The trip distribution cannot be totally based on the current student residence location. With the preschool relocating to the west there will be greater out-of-direction travel for those living in Glenwood Springs; 20 to 30 minutes round trip. Therefore it can be expected that the percent to and from the east will drop and the percent to and from the west will increase. n Suite 200 990 South Broadway Denver, Colorado 80209 n TEL 303 228 2300 Mr. Daniel Roussin, February 7, 2013, Page 2 Response We believe the distribution is not only appropriate for existing student locations, it is the distribution anticipated in the future independent of student population residence location. New Creation Church is located only a half mile west from the Interstate 70 Canyon Creek Exit 109 Interchange. It is expected that traffic arriving from and departing to the west will primarily use I-70 to access the preschool. The next interchange to the west is New Castle Exit 105, which is located approximately three miles west of New Creation Church. The travel time for traffic arriving to New Creation Church from the west via the New Castle Interchange 105 is approximately 4 minutes and 20 seconds. The travel time for traffic arriving to New Creation Church using the Canyon Creek Interchange 109 is approximately 1 minute. It is believed that traveling a slower speed for a longer distance will deter drivers from using the New Castle interchange and to use the Canyon Creek interchange instead. Therefore, the distribution as proposed is believed to be appropriate. Comment/Question 4.The weekday traffic to and from the church offices needs to be included in the driveway volumes. Response The existing traffic volume counter did not observe anyone using the access driveway between 7:00 am to 9:00 am and 4:00 pm to 6:00 pm during the morning and afternoon peak hours. The weekday traffic to and from the church offices is negligible during the peak hour of the generator of preschool traffic. There are two staff members that arrive at the Church at approximately 9:00 am and leave at 4:00 pm. These trips do not add to the traffic volume at the accesses during the preschool arrival and departure peak time periods. Comment/Question 5.A growth factor needs to be applied to the CR 138 traffic and the driveway traffic. Those growth factors do not have to be the same as for the highway nor the same as each other. Unless the church is currently at capacity, the ITE rates will probably apply for the long-term volume for the church traffic. The volumes in the 2003 permits for CR 138 and the driveway were 32 vph and 40 vph, respectively, or a combined volume of 72 vph. The current combined volume is 183 vph (Figure 4). Response The church is currently at capacity with its current attendance. It is hopeful that attendance will continue to grow, but the existing church building cannot be expanded any further with additional seats. In the case of future attendance expansion, it would be planned that additional services would be provided. Therefore, the peak hour trips generated by New Creation Church are anticipated to be effectively the same during any common peak hour into the future. Comment/Question 6.The report does not state the number of days per week the preschool will be opened. If it will be opened on Sundays that volume will need to be included in the Sunday projections. If not, that will need to a condition of the permit. Mr. Daniel Roussin, February 7, 2013, Page 3 Response The preschool will be a typical weekday, Monday through Friday facility. It will not be open or used on the weekends. Comment/Question 7.The waiving of the turn lane requirements because of the highway volumes is not automatic. A design waiver request will need to be submitted (Form 112). Response Understood, a design waiver form will be submitted. Comment/Question 8.It appears that the left-turn deceleration lane might not qualify for a waiver. The projected opposing traffic volume is 98 vph (Figure 6). The adjustments discussed above may push that volume above the 100 vph threshold. Both the through and the right-turning traffic is counted as opposing traffic since the left-turning traffic will need to wait for both. Response We believe that no adjustments are needed for the Sunday volumes shown in Figure 6 as the existing church is at capacity, so we believe the waiver request is appropriate. Comment/Question 9.The report needs to show the conversion to Passenger Car Equivalent traffic volumes. We prefer that the raw traffic counts are listed in a table and show the conversion to PCE in the same table. All traffic volume figures should be shown as PCE volumes and so noted on the figure. The street view in Google Maps shows two buses parked at the church. Response There were no heavy vehicles observed in the Sunday morning peak hour of the generator or weekday peak hour counts. Further, it is believed that the church will not generate any heavy vehicle traffic during the peak hours of the generator for the preschool. The church buses are used for Summer Camp and Retreat transportation. Comment/Question 10.Figure 6: The title says “Sunday” but the legend says “Weekday”. Response The title is correct, which reads Sunday; the legend is corrected in the resubmitted study. Comment/Question 11.Figure 7,et.al.: The title says “New Creation Church” but the data is for “New Creation Preschool”. Response The project is for a new proposed preschool at New Creation Church. The title has been revised. Mr. Daniel Roussin, February 7, 2013, Page 4 Comment/Question 12.In addition to addressing the warrants in the Access Code, the report needs to include the consultant’s recommendation to construct or not to construct auxiliary lanes as safety improvements. Response The thresholds for warrants of auxiliary turn lanes within the State Highway Access Code are set so low, so much lower than standard traffic engineering practice, it would be unlikely a case where warrants wouldn’t be met and actual turn lanes would be recommended. There aren’t believed to be any safety issues with the existing accesses. Adequate sight distances exist and the through volumes along US-6 are so low that there are not believed to be any safety or operational issues. Comment/Question 13.Include a recommendation for the design vehicle to be used for the design of the NTP plans. Response It is believed that the proposed access will not require reconstruction. Otherwise as previously mentioned, the church occasionally uses their buses for Summer Camp and Retreat transportation. These shuttles are the largest design vehicle using the property.
