The distance between these accesses is 112 feet. This analysis of the geometry utilized the ' long range traffic volumes. Since the sum of the conflicting left turns is 5 vehicles during the peak hours, this conflict was not considered to be critical. However, the traffic activity at the office building access was higher and had the potential for conflicts with the veterinary hospital traffic. The distance between the existing office building access and the proposed veterinary hospital access is 197 feet. Center left -turn lanes are ' not required at either location. Therefore, all left turns from Mason Street would occur from the through lane. Based upon the operations analysis, both of these left turns from the major street are at level of service A during the peak hours. Based upon recent research ("A Methodology for Using Delay Study Data to Estimate the Existing and Future Level of Service at Unsignalized Intersections," Heffron and Bezkorovainy, ITE, 1990), each left ' turn from the major street will be delayed 2 seconds. It is concluded that there will not be left -turn conflicts nor will the through traffic be delayed enough to require a center left -turn lane. C. Sight Distance Analysis Fort Collins staff requested a sight distance analysis of the veterinary hospital access to Mason Stree`. Fort Collins design 1 standards indicate that the corner sight distance on arterial streets should be 500 feet. The sight distance analysis was conducted in the field by locating the proposed access. Using a ' driver eye height of 3.5 feet, a sight line was determined in each direction which did not cross any property not included in this proposal. To the north, that sight line was along the sidewalk, as indicated in -Figure 6. To the south, that sight line was along the sidewalk and the street, also indicated in Figure 6. The corner sight distance to the north was determined to be 470 feet. This is slightly less than the required 500 feet. Since the 500 feet is based upon a 50 mph design speed and the posted speed i.s at 30 mph, the 470 feet is determined to be adequate. The sight distance to the south is greater than 1000 feet. 1 ' V. CONCLUSIONS/RECOMMENDATIONS Based upon the findings of these technical analyses, ' conclusions and recommendations are identified. - The proposed veterinary hospital, kennels, and retail store are feasible from a traffic engineering point of view. The proposed uses will generate approximately 190 vehicle trips per day. 5 iY I I I I 17 11 I I I I I 11 I I At CREGER DRIVE A - 5 k/ MANN 4 1, �** I CD rF 117ATER -7 :Lul co/ VETERINARY QI r .171 HOSPITAL r Z 0 CA 0 A,*�'A.OL vr AVAILABLE SIGHT DISTAN TO THE SOUTH < i A&: 4b 4p do *Wft � 0, I SIGHT DISTANCE ANALYSIS Figure 6 ' - In both the short and long range future, the operation at the key intersections is acceptable.

INTRODUCTION Dr. Rainey Corbyn, DVM, has proposed to build a veterinary hospital and kennel west of the Mann 4 Theater in Fort Collins, Colorado. The site is between Mason Street and the Colorado & Southern Railroad tracks. The site location is shown in Figure 1. The purpose of this study is to address the traffic impacts of this facility in the short range future (1991 plus this development) and the long range future (when traffic volumes increase to the projections developed by the City of Fort Collins). The focuses of this review are access requirements to Mason Street and the operation of the key intersections. The City of Fort Collins staff specifically requested evaluation of the sight distance for vehicles exiting this site and the potential for left- 11 turn conflicts along Mason Street. II. EXISTING CONDITIONS A. Existing Roads The major existing road in the area is Mason Street. Mason Street is located approximately 600 feet west of College Avenue and runs parallel to College Avenue. In southern Fort Collins, Mason Street runs from Monroe Street on the north through Harmony Road on the south. Mason Street is classified as an arterial street, but more accurately functions as a recirculation street for College Avenue. Since College Avenue has limited direct access to some properties, Mason Street allows access to occur easily to the properties between College Avenue and Mason Street. There is also a strip of land between Mason Street and the railroad tracks which has been developing as primarily specialty retail uses. �1 Between Horsetooth Road and Harmony Road, Mason Street has one 14 foot lane in each direction. There are 4 foot bike lanes on each side of the street and a 2 foot gutter pan. The total curb - to -curb width is 40 feet. There are sidewalks on both sides of Mason Street, except for a few short gaps on the west side of the street. There is a sidewalk along the entire frontage of the subject property. The posted speed limit on Mason Street is 30 mph in both directions. Mason Street has signals at the Horsetooth Road and Harmony Road intersections. There are no intermediate signals on Mason Street. Mason Street has the right-of-way at all intermediate street and driveway intersections. 11 '' 1 APPENDIX B 1 UIJ`311�IJG1l1 Zl;() I(JjE13SEL_' I lUfJS 1 1 Level -or -service rritr_r-in for ul,slnllali-ed tlltersec- tiolls nre statptl In very t)pllernl terrns, and are related to tlrllprnl t1p.1 ay rnnyr?t,, anal ysi. s (or- a stop- or 1 yield-rtmltr-ollyd intt?rtlr.r-boll rr:sulttl in solutiol,s fol- l:lle tnpoi:.I ty t)f teach 1 nl►n ol► gilt? mirror approaches. the I pvel-or-nrr vi rp to -I t•Ill' I n nre then based oil the 1 1-e513r-vp.. , bl" 1.111UMP119 cal'ntA tY t,f the 101117 Ill tlllesti011, e;lpressnt.l ill I+assenyer cnrA leer- hour IhCf'll) . 1 f'tF5FItVF IIY LFVrI. oi- EXhFC1EU UCLnY TO IhL'I'I1) 51=1WICE I.1IM011 9111FEf 1 or—FIC ----------------------•---------------------------------- 1 '1t.111 n Little or no dal ay ►-:-"•'?`? b Short traffic delays C Avnrane tl-a r f i c dpl. ays 1) Long trarf is dt?lays F_- Very lontl traffic delays x r- lib►hen dr?nlnrll.l voll-nnp pncr:.rlJs the cnpcity or the large, p)l tr-emp. l►el nys will be nnr_al-ultel ed with queui ny which may rntlnp sevtnty rollul?t)t:ft.)ll affertirlg other- traffic ' rtlovemrnts lit the interser-tiorl.

Existina Traffic Conditions Peak hour traffic counts were obtained at three Mason/driveway intersections near the subject property. Counts were obtained during the morning, noon, and afternoon peak hour of the street in October, 1991. The peak hour traffic counts are shown in Figure 2. Based upon historic peak hour versus daily traffic information on similar streets in Fort Collins, the traffic on Mason Street north of Creger Drive is between 7000 and 7500 vehicles per day. The existing peak hour operation at the busiest counted intersection is shown in Table 1. Calculation forms are provided in Appendix A. This operation is acceptable. Acceptable operation is defined as level of service D or better. A description of the level of service at unsignalized intersections is provided in Appendix B. Two accesses (theater and parking lot) were not analyzed since the turning volumes at these intersections were much lower than that of the office building intersection. The through volumes on Mason Street were within a few percent of each other at all intersections. C. Surroundina Land Uses The proposed veterinary hospital will eventually be bordered on at least three sides by some type of commercial uses. However, at this time, the adjacent parcels to the north and south are vacant. The parcel to the west of the proposed veterinary hospital across the railroad tracks is currently vacant. There is a 4-plex theater (Mann 4 Theater) and an adjacent theater parking lot east of the site. III. FUTURE TRAFFIC PROJECTIONS A. Development Assumptions Two future years were analyzed. The short range future included the existing traffic plus the proposed veterinary hospital traffic. The long range future included the existing traffic, factored to reflect daily volume of 10,000 on Mason Street, plus the proposed veterinary hospital traffic. In all available traffic projections developed by the city, a daily volume of 10,000 has been the highest shown for Mason Street. This is likely the maximum for a two lane street. With this volume, it is assumed that the parcels to the north and south of the veterinary hospital will be occupied by commercial uses. The veterinary hospital and approximately 340 feet of frontage the site plan of this facility. 2 kennels will be on a parcel with on Mason Street.

B. Site Trite Generation Normal trip generation of a proposed use is estimated using the latest publication of Trip Generation prepared by the Institute of Transportation Engineers. However, the use of a veterinary hospital and kennels is not one of the uses listed in this document. Therefore, the trip generation was estimated from information supplied by Dr. Rainey Corbyn, DVM, developer and owner of the proposed facility. The proposed facility will be developed in phases with the hospital and half (50) of the kennels as the first phase. A retail (animal related items) facility and the remainder of the kennels would be developed at a later phase. The veterinary hospital will open at 7:30 AM and close at 5:30-6:00 PM. The kennel and store would have the same hours. It is expected that there would be 4 visits per hour to the hospital. This results in 80 trips per day and four vehicles in and 4 vehicles out during the analyzed peak hours. The kennel operation will not be as busy and will be unpredictable with regards to when patrons would arrive. It is estimated that the kennel operation would generate 4 visits per day, resulting in 8 vehicle trips per day. To create a worst case, it is assumed that one visit would occur during each of the analyzed hours. A high estimate of the retail traffic is 4 vehicles per hour. While some of the retail visits will be by the same people visiting the veterinary hospital, for analysis purposes, a conservative approach was taken. It was assumed that all retail traffic would be new traffic. It was assumed the employees would add another 20 trips per day with appropriate amounts during the analyzed peak hours. Table 2 shows the breakdown of trips by the various uses on this parcel. The total shows that there would be approximately 190 daily vehicle trips with 20, 22 and 20 occurring in the analyzed peak hours. The analyzed peak hours were selected to reflect the times when both the street traffic and site generated traffic were at their highest. C. Trip Distribution Trip distribution for the newly generated trips was based upon the distribution of residential area in/near Fort Collins. Most veterinary hospital generated trips will be home based. It was assumed that 70 percent of the traffic would be to/from the north and 30 percent of the traffic would be to/from the south. 3 D. Traffic Assignments Utilizing the trip generation estimates and the distribution assumptions, projected site generated peak hour vehicle trips were assigned to the intersections on this segment of Mason Street. Although it is expected that this facility would be developed on a phased basis, the assignments assumed full development at both the short range and long range future, so that an update to this traffic study would not be required if the developer/owner decided to fully develop sooner than anticipated. Figure 4 shows the morning, noon, and afternoon peak hour assignments with the existing traffic on this segment of Mason Street. Figure 5 shows the morning, noon, and afternoon peak hour traffic with the existing traffic factored to reflect a daily volume of 10,000 on this segment of Mason Street. IV. TRAFFIC IMPACTS A. Traffic Operation Using the peak hour traffic volumes presented in Figure 4, the key intersections will operate as shown in Table 3. Calculation forms are provided in Appendix C. The key intersections were determined to be the access to the veterinary hospital site and the north access to the office building to the south. The office building access was determined to be a key intersection since the times of highest activity at this intersection would be the same times as the highest activity at the veterinary hospital. Although there is another access closer to the veterinary hospital access, it only serves the parking lot south of the movie theater. The activity at the theater is very low (none observed during traffic counting times when the veterinary hospital activity would be at its peak). Therefore, it was determined that the potential for conflicts did not and would not exist in this segment_..o.f—Mason Street. The access to the office building is approximately 60 feet south of the parking lot access. With the existing geometry, the two key intersections operate acceptably. Using the peak hour traffic volumes presented in Figure 5, the key intersections will operate as shown in Table 4. Calculation forms are provided in Appendix D. With the existing geometry, the two key intersections operate acceptably. D. Left -turn Conflicts on Mason Street Fort Collins staff requested an analysis of the potential for left -turn conflicts on Mason Street between the existing access to the parking lot on the east side and the proposed access to the 4
