Reynolds Wayne Timura, Next Level Development Angie Milewski, BHA Design Allen Ginsborg, NewMark Merrill Mountain States Joe Olson/Ward Stanford, Fort Collins Traffic Operations FROM: Matt Delich DATE: January 29, 2013 SUBJECT: Link-N-Greens PDP Transportation Impact Study Amendment (File: 1257ME02) This memorandum provides trip generation and operational analyses of the key intersections due a change (increase of floor area) in the retail/commercial portion of the Link-N-Greens PDP project. This memorandum is an amendment to the “Link-N- Greens PDP Transportation Impact Study” (LNGPDPTIS) January 2013. It also addresses Traffic Operations Comment Number 4 as contained in the City staff letter RE: Link-N-Greens, PDP130001, Round 1, dated January 25, 2013. The future year analyses in the LNGPDPTIS utilized the 2010 Highway Capacity Manual (2010 HCM). Based upon various reviews and discussions with Fort Collins Traffic Operations, the 2010 HCM procedures were found to be inconsistent. Therefore, the analysis techniques in the 2000 Highway Capacity Manual (2000 HCM) were used for all intersections in this exercise. The scope of this exercise was discussed with Joe Olson, Fort Collins Traffic Engineer. This memorandum analyzes the impacts of an increase in floor area in the retail/commercial portion of the development on the 2018 future. It also compares the new trip generation versus that analyzed in the “Link-N-Greens ODP Transportation Impact Study,” (TIS) August 2012. The new site plan for the commercial/retail area is shown in Figure 1. The entire Link-N-Greens site plan (used in the LNGPDPTIS with the new commercial/retail area) is provided in Appendix A. The short range (Year 2018) included the development of Phases 1-4 and the new commercial/retail area. Trip Generation, 9th Edition, ITE was used to estimate the daily and peak hour trip generation for the Link-N-Greens PDP. Table 1 shows the expected trip generation for Phases 1-4 and the new commercial/retail area. The new trip generation resulted in 7626 daily trip ends, 927 morning peak hour trip ends, and 998 afternoon peak hour trip ends. Figure 2 shows the short range (2018) site generated peak hour traffic for the Link-N-Greens PDP. DELICH Link-N-Greens PDP TIS Amendment, January 2013 ASSOCIATES Background traffic projections for the short range (2018) future horizon were obtained from the cited LNGPDPTIS and are shown in Figure 3. The traffic volumes generated by the proposed Link-N-Greens PDP (Figure 2) were added to the background traffic volumes (Figure 3) to produce the total traffic volume forecasts for the short range (2018) future. Figure 4 shows the short range (2018) total peak hour traffic at the key intersections. Operation analyses were performed at the Mulberry/Lemay, Lemay/Magnolia, Lemay/Lincoln, Lemay/Vine, Lemay/RT Access, Lemay/¾ Access, Lincoln/East Access, and Lincoln/West Access intersections. The operations analyses were conducted for the short range future, reflecting year 2018 conditions. Each appendix (containing the calculation forms for the operational analyses) lists the adjustments made to the signal timings at each intersection that differ from the City of Fort Collins analyses. At the Mulberry/Lemay intersection, there will be geometric improvements that are reflected in all subsequent analyses. These are: dual eastbound left-turn lanes and three westbound through lanes. These improvements are expected to be constructed in the next 1-2 years. The intersections were evaluated using techniques provided in the 2000 HCM. A description of level of service for signalized and unsignalized intersections from the 2000 HCM and a table showing the Fort Collins Motor Vehicle LOS Standards (Intersections) are provided in Appendix B. The Link-N-Greens PDP site is in an area termed “commercial corridor.” In areas termed “commercial corridors,” acceptable operation at signalized intersections during the peak hours is defined as level of service D or better for the overall intersection, and level of service E or better for any leg or movement. At unsignalized intersections, there is no minimum acceptable level of service for any approach leg for an arterial/collector or local and collector/local intersection. In such areas, it is expected that there would be substantial delays to the minor street movements at unsignalized intersections during the peak hours. This is considered to be normal and acceptable in urban areas. Using the traffic volumes shown in Figure 3, the key intersections operate in the short range (2018) background traffic future as indicated in Table 2. Calculation forms for these analyses are provided in Appendix B. The key intersections will operate acceptably during the peak hours. Table 3 shows the short range (2018) total morning and afternoon peak hour operation at the key intersections. Calculation forms for these analyses are provided in Appendix C. The Mulberry/Lemay intersection will not achieve level of service E or better for all movements during the afternoon peak hour with the expected geometric improvements mentioned earlier. Therefore, dual southbound left-turn lanes were added in order to achieve acceptable operation. The operation shown in Table 3 for the Mulberry/Lemay intersection also reflects the dual southbound left-turn lanes. The other key intersections will operate acceptably. Table 4 shows the trip generation from the “Link-N-Greens ODP Transportation Impact Study,” August 2012. The trip generation from the ODP resulted in 8220 daily trip ends, 996 morning peak hour trip ends, and 1222 afternoon peak hour trip ends. Table 5 shows the full development trip generation for the Link-N-Greens property with this proposal. The trip generation for the Link-N-Greens property resulted in 8746 daily trip ends, 1139 morning peak hour trip ends, and 1202 afternoon peak hour trip ends. Based upon a comparison of Tables 4 and 5, the current proposal for full development of the Link-N-Greens property will generate more daily, more morning peak hour, and less afternoon peak hour trip ends than that calculated in the “Link-N-Greens ODP Transportation Impact Study.” Since the forecasted traffic is lower in the afternoon peak hour and during the morning peak hour the key intersections are not problematic, it is concluded that the current proposal for Link-N-Greens is compatible, from an operations perspective, with that analyzed in the “Link-N-Greens ODP TIS.” With the development of the Link-N-Greens PDP, it is concluded that the key intersections will operate acceptably with recommended geometry and control. The increase in the commercial/retail area will not significantly impact the key intersections. The current proposal for Link-N-Greens is compatible with that analyzed in the “Link-N- Greens ODP TIS.” Do not hesitate to contact me if you have questions or require additional information.
