3 Bennett Pit Traffic Impact Study 1. Introduction Northern Colorado Constructors (NCC) is proposing to develop the Bennett Pit east of Weld County Road 23 (WCR 23) adjacent to the intersection with Weld County Road 24 (WCR 24). Figure 1 shows the location of the site. The development will start as a quarry and may expand to include concrete and asphalt batch plants. The quarry is expected to be operational in Year 217, and the addition of the batch plants is expected by Year 222. The quarry and ultimately the batch plants are expected to operate Monday through Saturday during daylight hours with the end of the business day at 4: p.m. The study has been prepared based on the Weld County traffic impact study requirements Project Description 2.1 Existing and Proposed Streets and Intersections The intersection of WCR 24 / WCR 23 will provide access to the development. It is a T-intersection of two lane collector roads. The intersection has side street stop control for the eastbound traffic on WCR Study Assumptions The following assumptions were utilized for this study. Short Term Horizon. The Bennett Pit is assumed to be operational in Year 217, therefore, the short term horizon is Year 217. Long Term Horizon. The long term horizon is assumed to be Year 222 when the quarry and batch plants will potentially be operational. Growth in Background Traffic. Traffic on WCR 23 and WCR 24 is expected to grow based on projections that are contained in the 235 Transportation Plan 2. Saturation Flow Rate. The saturation flow rate was assumed to be 1,6 passenger cars / hour / lane which is typical in rural areas. Peak Hour Factor. The peak hour factor for the existing movements was based on the count data. For new movements, the peak hour factor was assumed to be.85. Truck Percentage. Based on the data collected for the study, the percentage of trucks was assumed to be 6%. This assumes that trucks have three or more axles. 1 Weld County Engineering and Construction Criteria.

4 3. Existing Traffic Volumes Traffic count data for the study were collected on Thursday December 1, 216 by All Traffic Data. The existing daily volumes are summarized in Table 1, and the existing peak hour volumes are summarized in Table 2. Traffic count data are contained in Appendix A. 4. Crash Data STS requested the most recent three years of crash data from Weld County for the intersection of WCR 24 / WCR 23. The report provided by Weld County contains a list of several incidents at or near the intersection (see Appendix B). Six of the incidents between December 25, 214 and November 29, 215 were crashes. They are highlighted on the report. There wasn t enough information provided by Weld County to determine the cause of the crashes. 5. Site Generated Traffic Volumes 5.1 Trip Generation Quarries and batch plants are not land uses addressed in the ITE Trip Generation manual 3. Therefore, the trip generation was determined based on information that was provided by J&T Consulting. The truck and passenger vehicle traffic for each of the uses is summarized in Table 3. When the quarry and the batch plants are fully operational, the daily and peak hour traffic volumes on an average weekday will include 212 truck trips and 66 passenger vehicle and light duty truck trips. 5.2 Trip Distribution and Assignment The trip distribution for the truck traffic was provided by NCC and is shown in Figure 2. NCC assumes that approximately 5% of the truck traffic will occur on WCR 24, and the other 5% will be on the south leg of WCR 23. Passenger vehicle and light duty truck traffic will be associated with employees and vendors. That traffic is assumed to be divided equally between the three directions of travel from the site. The daily trip assignment is contained in Table 1 and the peak hour trip assignment is contained in Table 2. The distribution of traffic entering and exiting the site was based on count data collected at the Pikeview Quarry in Colorado Springs. 6. Future Traffic Volumes Background traffic volumes (without the development traffic) were estimated by using the projected volumes for each leg of the intersection and inflating the existing volumes to appropriate levels based on the projected volumes that are contained in Appendix A of the 235 Transportation Plan. Tables 1 and 2 contain the Year 217 and Year 222 background traffic volumes. The projected peak hour volumes at the completion of the project were estimated by adding the traffic that is expected to be generated by the Bennett Pit to the background traffic volumes (see Tables 1 and 2). 3 Trip Generation, 9 th Edition.

5 6.1 Auxiliary Lanes STS reviewed the need for auxiliary lanes at WCR 24 / WCR 23 following the opening of the quarry in Year 217 and the batch plants in Year 222. Weld County has criteria for auxiliary lanes that are contained in Section 6.6 of the Weld County Engineering and Construction Criteria. The following thresholds trigger the need for the construction of auxiliary lanes on arterial and collector roadways. Left Turn Declaration Lane. A left turn deceleration lane is required when peak hour volumes exceed 1 vehicles hour. Right Turn Deceleration Lane. A right turn deceleration lane is required when peak hour volumes exceed 25 vehicles hour. Right Turn Acceleration Lane. A right turn acceleration lane is required when peak hour volumes exceed 5 vehicles hour. A second criterion is that the right turning traffic would be turning into a single lane. Based on the thresholds, a northbound left turn lane and an eastbound right turn lanes are currently warranted. However, the volumes at the intersection are low enough that the auxiliary lanes would not make a difference in the operation of the intersection. The County s criteria only considers the turning volume, but not the through volumes. STS reviewed the criteria in NCHRP because that criteria considers turn lane and through volumes. Figures 3 and 4 contain an evaluation of the need for a northbound left turn and right turn lanes. It can be seen that neither lane is required based on NCHRP 279 because the volumes at the intersection are very low. 7. Level of Service Analysis To evaluate the performance of the intersections within the study area, the Level of Service (LOS) was calculated using Synchro software. This software package utilizes criteria described in the Highway Capacity Manual 5. LOS is a measure used to describe operational conditions at an intersection. LOS categories ranging from A to F are assigned based on the predicted delay in seconds per vehicle for the intersection as a whole, as well as for individual turning movements. LOS A indicates very good operations, and LOS F indicates poor, congested operations. Acceptable intersection operation in rural areas is typically considered LOS C or better. The level of service for stop controlled intersections is based on the lowest letter grade for the side street movements. The level of service analysis shows that the intersection of WCR 24 / WCR 23 is currently operating at LOS A. The level of service is expected to drop to LOS B in the Year 217 and Year 222 total traffic volume scenarios. Table 4 summarizes the operational analysis and the Synchro output is contained in Appendix C. 4 Intersection Channelization Design Guide. National Cooperative Highway Research Program Report 279.

6 8. Conclusions STS has drawn the following conclusions based on the analysis performed in the study. The intersection of WCR 24 / WCR 23 is expected to operate at LOS B in the Year 217 and Year 222 total traffic volume scenarios. No auxiliary lanes are required as a result of the traffic generated by the Bennett Pit. Sustainable Traffic Solutions, Inc. 4 J&T Consulting, Inc. Weld County, Colorado March 3, 217
