It is also ed that by the year 2007, Harmony Road was shown to have a six -lane ss 'section. There may be merit in making all the improvements to the cnony/Ziegler intersection when Harmony Road is widened to the six -lane ss section. r HP It is concluded that the key intersections will operate acceptably. HP HTP, Buildings C, D, E, and F can be developed and occupied with access at'the Harmony/Technology/HP West Access intersection. A signal will be warranted at the Harmony/Technology/HP West Access intersection. �a The directional distribution of the generated trips was determined by analyzing the current distribution at the HP facility on the north side of Harmony Road. Since this is a short range (2004) analysis, this is the most relevant trip distribution available. Figure 5 shows the trip distribution used for the assignment of site generated traffic for Buildings C, D, E, and F. Figure 6 shows the assignment of the site generated traffic at the key intersections. Year 2004 background traffic was developed for the key intersections. The existing traffic counts were adjusted to account for the opening of Technology Parkway. The Celestica traffic was reassigned to both Ziegler Road accesses and an access to Technology Parkway. It was assumed that by the year 2004, at least 250 dwelling units within proposed developments (Imago, Willowbrook, Brookfield) to the south and east of HP HTP would be occupied. As a conservative analysis, it was assumed that primary/sole access would be via Technology Parkway to Road A to Cambridge Drive. The Harmony/Cambridge intersection would not allow full -turning movements by the year 2004. It was assumed that Harvest Park/Sage Creek and Fossil Lake Village would be developed by the short range future. This is considered to provide a conservative scenario, since this is not likely to be the case. Traffic volumes at the Harmony/Ziegler intersection were increased at the rate of 1.5 percent per year. Turning volumes at the HP West Access were held constant. Figure 7 shows the short range background traffic at the key intersections. The site generated traffic from Buildings C, D, E, and F was added to the background traffic at the key intersections and is shown in Figure 8. As a matter of policy, traffic signals are not at any location unless warrants are met according to the Manual on Uniform Traffic Control Devices. Using the traffic forecast shown in Figure 8, a signal warrant would be met at the Harmony/Technology/HP West Access intersection. The peak hour signal warrant analyses are provided in Appendix C. Using the short range background peak hour traffic (Figure 7), the key intersections operate as indicate in Table 3. Calculation forms are provided in Appendix D. The analyses assumed that Harmony Road would remain as a four -lane facility. The key intersections will operate acceptably. At the Harmony/Technology/HP West Access intersection, in order to achieve acceptable operation in the afternoon peak hour, split north/south phasing is recommended. In addition, the northbound geometry on Technology Parkway should have a left -turn lane, a combined left- turn/through lane, and a right -turn lane. This will not involve a change in the width of Technology Parkway, but rather a striping exercise. When the Harmony/Cambridge/HP East intersection is opened to full traffic movement, the striping on Technology Parkway can be changed to separate lanes for each traffic movement. Using the short range total peak hour traffic (Figure 8), the key intersections operate as indicated in Table 4. Calculation forms are provided in Appendix E. The key intersections will operate acceptably. The recommended geometry in shown in Figure 9. Even though the conventional "rule of thumb" indicates that a dual left -turn lane may be needed for the southbound left -turns at the Harmony/Ziegler intersection, the analysis indicates that sufficient green time can be provided for Ziegler Road such that acceptable operation is achieved. It is expected that the 300 left - turn threshold would only occur during the morning peak hour. If the City desires to implement dual left -turn lanes on this leg of Ziegler Road, this can be done.

DATE: January 8, 2001 SUBJECT: HP HTP PDP, Buildings C, D, E, and F Transportation Impact Study (File: 0045ME06) co N m This memorandum provides transportation analyses pertaining to the building and occupancy of four office buildings within the Hewlett-Packard Harmony Technology Park (HP HTP) located south of Harmony Road and east of Ziegler Road (CR9) in Fort Collins. The L; site location is shown in Figure 1. These analyses provide an o addendum to the "HP Harmony Technology Park PDP Traffic Impact d Study," November 2000. As discussed with City staff, it specifically addresses, the impacts to specific intersections in the short range (2004) future. It is expected that buildings C and E will be occupied in the second quarter of 2002 and buildings D and F will be occupied in the fourth quarter of 2003. Therefore, the year 2004 was selected as the analysis year. Figure 2 shows the site plan of the four buildings covered in this development proposal. This proposal is for Buildings C, D, E, and F of the HP HTP PDP development proposal which is currently in the City development review process. It is intended that site access will be via Technology Parkway which will be built south of Harmony Road, across from the existing HP West Access. Figure 3 shows the existing peak hour traffic at the key intersections. Raw traffic count data is provided in Appendix A. Harmony Road is a four lane arterial street with auxiliary turn lanes z at Ziegler Road and at the HP West Access. The Harmony/Ziegler wintersection is signalized. The Harmony/HP West Access has stop sign w control on the HP West Access. The traffic counts shown in Figure Z 3 were collected over a number of days. Therefore, they were Wadjusted and balanced between intersections and are shown in Figure 4. Table 1 shows the existing operation at the key -intersections. o Calculation forms are provided in Appendix B. Level of service a descriptions are also provided in Appendix B. The key intersections rat operate acceptably overall. The southbound minor street left turns a operation at level of service E during the afternoon peak hour. z a Trip generation for the development of Buildings C, D, E, and W F is shown in Table 2. The Office Park land use (Code 750) from Trip go Generation, 6th Edition, ITE was used in estimating the trip L) generation. Based upon traffic counts at the existing HP facility, a the trip generation was factored by 80 percent to account for use of ¢ alternative modes and existing transportation demand management F' techniques which are currently in use at the existing HP facility.
