The project is a redevelopment of an existing feed store. The project is considered to be in the “River District” and is consistent with the adopted redevelopment policies of the area. The project will preserve the historic feed store and add apartments, office space and a high quality restaurant. The City recently improved Linden with roadway enhancements, parking, and pedestrian features. For analysis purposes, the project will be built in one-phase. Figure 1 on the following page is a vicinity map displaying the location of the project. 2.0 Agency Discussions Initial discussions with City staff indicated that an intermediate study traffic study as described in Chapter 4 of the Larimer County Urban Area Streets Standards (LCUASS) would be appropriate for this particular development. The project is considered infill and redevelopment and there are no recently approved projects in the area that need to be considered in the analysis. There are no perceived capacity or infrastructure deficiencies in the immediate area that are of concern at the on- set of this study. Appendix A contains the form (Attachment A), which outlines the agreed to scope of the study. Site Figure 1: Vicinity Map 3.0 Existing Conditions 3.1. Current Traffic Recent peak hour turning movements at the key intersections were obtained as part of this study. The City of Fort Collins Traffic Operations Department provided counts at the intersections of College/Willow and Jefferson/Linden. The counts were taken in 2011 but are still considered valid since traffic conditions are believed not to have changed significantly. The intersection of Willow and Linden was counted during January 2013. The area is currently under redevelopment and several new projects are being constructed. Morning and afternoon peak hour traffic counts at the key intersections are displayed in Figure 2. The peak hour counts were conducted in 15 minute increments for the period 7:30-8:30 AM and 4:30-5:30 PM. The peak hours between the two intersections do not correspond to each other due to the various time Feeder Supply, LLC ELB Engineering, LLC Transportation Impact Study 5401 Taylor Lane January 2013 Fort Collins, CO 80528 2 frames the counts were taken as well as different business that would draw traffic. The raw information regarding the turning movements is provided in Appendix B.

There have been city efforts over the years to make this portion of the city as an extension of the downtown area (a.k.a. “River District”). The project is located on the southwest corner of Linden Street and Willow. Willow Street on the north of the property is classified as a two-lane collector and the Master Street Plan. Portion of the roadway are complete but there are many sections that are substandard. It is a two lane roadway with bike lanes and a posted speed of 25 mph. Sidewalks are being constructed as development occurs in the area. The intersection of Willow and College is controlled by an 8-phase traffic signal. The pavement and markings appear to be well maintained. Linden Street is a north-south two-lane collector roadway that connects from Vine to the north into the downtown area. The city recently improved Linden to include diagonal parking, pedestrian lighting and enhanced sidewalks. The posted speed limit is 30 mph and the pavement and markings are in excellent condition. The intersection of Willow and Linden is adjacent to the site and is controlled with an all-way stop condition. The crosswalks are considered “enhanced” and the intersection is bulbed out for short crossing distances. The surrounding land uses in the area are varied from residential, business, industrial, and recreational. 3.3 Current Traffic Conditions Capacity analyses were performed at the key intersections to determine if existing deficiencies exist on the roadway network. The analyses followed the procedures of the Highway Capacity Manual 2000. Level of Service (LOS) is a qualitative term describing operating conditions and expressed in terms of delay. Table 1 below provides the definitions of LOS for both signalized and unsignalized intersections. Table 2 Feeder Supply, LLC ELB Engineering, LLC Transportation Impact Study 5401 Taylor Lane January 2013 Fort Collins, CO 80528 4 displays the results of the analyses. All key intersections currently operate at acceptable levels of service. The worksheets from the analyses can be found in Appendix C.

The project is located at the intersection of Willow and Linden in the downtown area of Fort Collins. There have been recent public roadway improvements in the area, particularly on Linden Street. Redevelopment in the area appears to be active with new construction in the vicinity of the project. For the purposes of analysis, the project is expected to be constructed during 2013 in one phase. The downtown is within easy walking distance, bike lanes are already constructed and the site is served by Transfort. Parking for the facility is being provided on-site and will access onto both Linden and Willow Street. Restaurant patrons will likely use the available on-street parking in the immediate area. A preliminary site plan is displayed in Figure 3. 4.2 Trip Generation Trip generation rates for the proposed project are based on the Trip Generation, 8th Edition manual prepared by the Institute of Transportation Engineers. The manual presents data from numerous trip generation studies for a variety of land uses from across the country. ITE Code 220, apartments was used in this analysis. The restaurant was code 932 (low turnover/high quality) and the general office is code 710. No trip reductions were assumed as part of this project although many trips, especially the restaurant will likely be attributed to walking and biking. The trip generation calculation is considered conservative since no trip reductions are incorporated into the analysis. Table 3 below summarizes the proposed trip generation for the project. For the entire project, during the morning peak hour, 96 trip ends can be expected and 99 trip ends can be expected from the project during the afternoon peak hours.

This high growth rate was selected between the City staff and ELB Engineering for two purposes. First, the area is expected to redevelop and evidence of this is in the area. The second reason was to provide a very conservative analysis of potential growth in the area. Background traffic for the year 2016 is displayed in Figure 6. Site-generated traffic was then added to the background traffic to determine the total traffic volumes at the key intersections. Total traffic for the year 2016 is displayed in Figure 7.

Table 4 displays the results of the background traffic analysis and Table 5 shows the results of the total traffic analysis to account for the project. As can be seen from the tables, each of the key intersections continues to operate at acceptable levels of service. Implementation of the project will not have an adverse Feeder Supply, LLC ELB Engineering, LLC effect on the operation of the intersections.

Traffic Signals Traffic signals are never installed until a warrant is satisfied under the Manual on Uniform Traffic Control Devices.. The Peak Hour Warrant, is usually the best indication of a whether or not a traffic signal will be needed in the future. Based on a review of the criteria, no new traffic signals will be required with this project. The key intersection of Willow and Linden as well as the access points will operate and good levels of service under and safely under STOP sign control. 7.2 Auxiliary Lanes A review of the LUCASS requirements regarding auxiliary lanes was undertaken as part of this study. Based on this review, no new auxiliary lanes are required as part of this project. Feeder Supply, LLC ELB Engineering, LLC Transportation Impact Study 5401 Taylor Lane January 2013 Fort Collins, CO 80528 13 8.0. Multi-Modal Evaluation Section 4.5.3 (B) of the Larimer County Urban Area Street Standards requires that projects undergo a level of service analysis for alternative modes of transportation. The modes of transportation that must meet LOS standards are bicycles, and pedestrians. Transit service LOS must also be analyzed at the time of development review. However, transit LOS is not part of the Adequate Public Facilities test. The area of interest for the alternative modes of transportation is shown below in Figure 8. site Figure 8: Multimodal Evaluation Area 8.1 Pedestrian Level of Service The project area was evaluated for compliance with the pedestrian level of service standards. The site is located with a Pedestrian District as determined by the Fort Collins Pedestrian Plan. Primary destinations from the sight would include the downtown area to the south and the North Side Aztlan Center. Feeder Supply, LLC ELB Engineering, LLC Transportation Impact Study 5401 Taylor Lane January 2013 Fort Collins, CO 80528 14 Feeder Supply, LLC ELB Engineering, LLC Transportation Impact Study 5401 Taylor Lane January 2013 Fort Collins, CO 80528 15 The project will construct sidewalks along its north property line that will eventually connect to the Northside Aztlan Center. Sidewalks and streetscape have recently been improved by the City of Fort Collins from the site, southward to the downtown area. The area to the south has been improved to its future condition and is constructed to a pedestrian scale. Directness – There direct sidewalk connection to the south and to the north of the site. The sidewalks exceed city standards and were constructed by the City. Sidewalk connections to the west and east of the site will occur at the time of redevelopment. Continuity – The sidewalk system that is and will be in place has good continuity to the downtown area. As the area redevelopments, east-west connections will be in place. The City should consider a capital project to correct this deficiency. Street Crossings – The intersection of Willow/Plum was recently reconstructed and meets all the standards for street crossings. The intersection of Jefferson/Linden has 5 lanes of traffic to cross, crosswalks, and pedestrian phasing. There are unobstructed views, sidewalks, and character and good lighting levels. The intersection of College/Cherry/Willow has recently been reconstructed and has good pavement markings, enhanced crosswalks, actuated pedestrian phases, and good lighting. The North College Access Control Plan shows this intersection being converted in the future to a limited movement intersection. There are six lanes of traffic to cross in the east-west direction but the intersection was recently improved without pedestrian refuge. Visual Interest and Amenity – The area is along the site has been improved and is considered visually appealing. Security – The sidewalks in the area are lit and good sight distances are available. 8.2 Bicycles Level of Service The project will meet the bicycle level of service standards for both north/south and east/west connections. Bike lanes currently exist on Linden and Willow which connect to the City’s bike system. There is also a direct connection to the Poudre Trail system to the north of the site. 8.3 Transit Level of Service According to the LUCASS Multimodal Level of Service Manual, transit level of service for the City of Fort Collins is based on the routes and service levels planned for the year 2015. However, the Manual was written in 1997 and is significantly outdated and no longer considered valid. The transit LOS analyses are therefore based on the 2010 Transfort Strategic Plan. The analysis is based on 4 factors – hours of weekday service, weekday frequency of service, travel time factor, and peak load factor. The LOS standard for transit is “B” based on this site location. LOS B is defined as 3 out of the 4 requirements being satisfied. The current transit map shows that the site will have close access to Routes 8 and 81 which will have direct access to the downtown area and the CSU campus. The site is also within a short walking distance to the downtown transfer center. Hours of Weekday Service: Since Route 8 and 81will take people directly to the downtown transit center as well as good connection to the Mason Corridor, it is assumed that the site will be served by 18 hours of service on an average weekday. The standard can be assumed to be met. Weekday Frequency of Service: Since the site is adjacent to an identified route of high frequency transit service, the minimum of 15-minute service is met. Travel Time Factor: The travel time factor is portal-to-portal travel time divided by auto travel time (peak hour). The standard for the criteria is for the travel time in bus to be no more than two times that of the automobile. The standard is met for 3 out of the 4 destinations which is acceptable. Table 6 Transit Travel Time Comparisons Destination Mode Distance (miles) Travel Speed (mph) Travel Time (hours) Walk/Park Time (hours) Transfer/ Wait Time (hours) Total Travel Time (hours) Time Differential (bus/auto) LOS Standard Met?

The standard requires that this value be ≤ 1.2. Based on the LOS Manual, for all Feeder Supply, LLC ELB Engineering, LLC Transportation Impact Study 5401 Taylor Lane January 2013 Fort Collins, CO 80528 17 Based on the above, the transit LOS achieved 3 out of the 4 criteria and is therefore the LOS is calculated at “B”, which is acceptable. 9.0 Conclusion This TIS assessed the impacts associated with The Feeder Supply Project redevelopment project located in downtown Fort Collins, Colorado. The project consists of redeveloping an older feed store into apartments, restaurant, and office space. The site lends itself to outstanding use of alternative modes of transportation. Based on the analyses, investigations, and findings documented in the various sections of this Transportation Impact Study, the following can be concluded. o Current operation is acceptable at all of the key intersections. o Operation at the key intersections will be acceptable under full build-out of the project. o For the entire project, and without assuming any trip reductions, during the morning peak hour, 96 trip ends can be expected and 99 trip ends can be expected from the project during the afternoon peak hours. o No new traffic signals or signal modifications will be required with the construction of the project. o No auxiliary lanes will need to be constructed with the project. o Multi-modal LOS standards can be achieved with the project. o The project is feasible from a traffic engineering perspective. Statement of Adequacy: The transportation facilities will be adequate and available to serve this development as contained in the Larimer County Urban Area Street Standards. All applicable LOS standards will be met since all transportation facilities are in place or will be in place upon issuance of a certificate of occupancy. future routes, the presumed peak load factor is 1.0 and therefore the standard is satisfied.
