Anticipated levels of service will meet or exceed City criteria. • Current and future bicycle levels of service will exceed those required by City standards. This site has direct access to access north -south on -street bicycle lanes which connect to east -west bicycle lanes. • Future transit operations are expected to achieve level of service '13' condi- tions. This level of service exceeds City standards. In summary, the transportation demands associated with Cherokee Flying Heights are considered negligible. They can be easily absorbed and accommodated by the current transportation system. Acceptable operating conditions can be expected in the vicinity of the development for the foreseeable future. 24 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:23PM P27 m ~_ ° o O t0 m N l0 a� E > E E E E E Ln (n N U* N H rt C9 N � N m c y E E E E E N m W M N �► O f✓ N LD r �a � Id LL E E U n m p .X m O N > C © h L6 N N O �Ff U � N co t G G C cn 0 U Q W W O Ip li U G 67 U to � � a A a c 0 O O O y fff LL a A � a G N Y m r m (A � O m N w N N cc m y d J CDG N V) m N x a � y m E O 2 C _'- O II x c o N V N ui U �UL) �� L U U U W � � w `v N O m m O C O a a 7 U � o U En d 'SLL O LL Ea o m F o Y y � 2 3 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:23PM P26 By 2015, it is expected that weekday service hours will be extended to at least ac- commodate any growth in demand and extended service hours can be anticipated. This is expected to result in a future LOS "B" as shown on Table 3. Since the site is located outside the designated mixed use centers and commercial corridors, the established goal of LOS 'D' is clearly exceeded. X. CONCLUSIONS Based upon the analyses, investigations, and findings documented in earlier sections of this report, the following can be concluded: Current roadway operations in the area of the Cherokee Flying Heights site are acceptable during all peak hour periods. • Site traffic associated with the Cherokee Flying Heights development is ex- pected to be 10 morning peak hour trips, 12 afternoon peak hour trips, and 129 trips per day, These trips are considered minor. The impacts of site generated traffic are negligible. This is evidenced by the finding that overall intersection levels of service remain constant be- tween current and short-term conditions with Cherokee Flying Heights fully built. • No site related transportation improvements are needed. The proposed full movement access to Taft Hill Road will not require any auxiliary lanes. • Per City criteria, traffic operations will be acceptable with the proposed de- velopment. 22 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:23PM P25 IX. TRANSIT A. Existing Conditions Transit stops are currently located in the vicinity of the Taft Hill Road -- Mulberry Road intersection. Bus route 4 provides 30-minute service to this location. Service is available from 6:18 A.M. to 6:44 P.M., which is about 12% hours per day. The current peak load factor is less than 1.20 for a representative weekday peak hour. B, Planned Improvements No improvements are planned in the immediate area of the site. Passenger demand is expected to be the driving force behind increases in the frequency of service and hours of operations. It is expected that Transfort will adequately serve this area in concert with ridership demands. C. Levels of Service Using the criteria presented in the Manual, current and future transit levels of service were determined. The current travel time factor was calculated for transit and automobile trips to Fort Collins High School, Foothills Fashion Mail, the CSU Transit Center, and the down- town area as defined in the Manual. Bus travel times and transfer times were ex- tracted from the current Transfort bus schedule brochure. A 3-minute walk time from the site to the bus stop locations at the Taft Hill Road — Mulberry Street intersection was assumed. Auto travel times were field measured as part of this study. Auto park and walk times were assumed to total 5 minutes. Current travel times for bus and auto traffic were estimated and resulted in a travel time factor of 2.03. 21 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:23PM P24 a Q e[ 2 O N c•] }' -moo o a y D � C y 0 �i A c Z L p) l0 0 N U c U !1. 2 0 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:22PM P23 VIII. BICYCLE FACILITIES A. Existing Conditions Taft Hill Road currently has on -street bicycle lanes and borders the site on the east. These lanes connect to established bicycle routes on Mulberry Road and LaPorte Avenue. Excellent connectivity is therefore provided in both the north -south and east - west directions. B. Planned Improvements No improvements are planned on the area bicycle system in conjunction with this development. C. Levels of Service The City of Fort Collins defines level of service based upon connectivity of the site to existing and planned bicycle facilities. In this instance, the site abuts existing bicycle lanes on Taft Hill Road resulting in excellent connectivity in all directions. This results in level of service 'A' being realized both currently and in the future. The bicycle level of service work sheet is presented on Table 2. 19 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:22PM P22 U m m Cn m co m m m U u7 m c 0 m U :C w m u c 4 rO V m O Q C O m N E 7 E C E I II IIJZ w U .S m w 0 m w E ' E 'e ' 0 E 'c ,� 'c m n nc m m41 E E o E a E ft C O u :E U c 0 W O O f w Q a a o a m w C � m O C O C O C O W '.- o cmi m m m c4J U w Q N N � •- m� c 1 8 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:22PM P21 along Taft Hill Road is considered sufficient to serve this site and pedestrians using this facility. C. Levels -of -Service The City of Fort Collins multi -modal transportation Level -of -Service Manual (the Manual) was used to assess both current and future pedestrian conditions. It was determined that the site fits the "School Walking Area" classification due to its rela- tionship to Poudre High School. The high school is about 0.7 miles away from the Cherokee Flying Heights site. The best routing for students to use would be south on Taft Hill Road, west on Mulberry Street and north on Impala Drive. Sidewalks are available on the appropriate sides of the street and there are no required crossings of the arterial streets. The distances between Putnam and Irish Elementary Schools and the site were also investigated as part of this study. Both elementary schools are over one mile from the site based upon the most logical and efficient walk routes. Putnam Elementary School, however, is the closest to Cherokee Flying Heights. While not required, a pedestrian analysis was conducted for the route between Cherokee Flying Heights and this elementary school. Five factors were assessed under current and future conditions. These classifications provide the basis for determining minimum level of service criteria. Based upon the investigations into current and future pedes- trian levels of service, acceptable levels of service are currently being and will con- tinue to be experienced. The pedestrian level of service worksheet is presented on Table 1. As shown, all pedestrian factors are expected to approximate acceptable conditions. 17 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:22PM P20 As shown above, acceptable operations are expected under short-term total traffic conditions with the existing roadway geometry. VII. PEDESTRIAN FACILITIES A. Existing Conditions The existing sidewalk system was field reviewed within 1,320 feet of the Cherokee Flying Heights site. Sidewalks currently exist along the west side of Taft Hill between LaPorte Avenue and Mulberry Road. Pedestrian facilities have been installed under earlier editions of City design stan- dards. This has resulted in older designs; however, all facilities were determined in generally usable condition. Pedestrian ramps are available at critical intersections and traffic signals facilitate crossings at the Taft Hill Road intersections with LaPorte Avenue and Mulberry Road. Generally speaking, Taft Hill Road has sidewalk along its west side adjacent to the site, LaPorte Avenue has sidewalk along the north side with significant breaches along the south side and Mulberry Road has sidewalk along both sides. Side streets leading to the elementary schools have sidewalk on both sides. Impala Drive from Mulberry Street to the north (leading to Poudre High School) has continuous sidewalk along its east side with partial sidewalk along the west side. Sidewalks adjacent to the site are 4 feet wide. In other areas, they range from 3 to 5 feet. B. Planned Improvements The pedestrian system planned internal to Cherokee Flying Heights will conform to current City criteria. It will connect to the external pedestrian system thereby accom- modating and complimenting the integration of pedestrians into the site. No off -site improvements are planned in conjunction with this project. The current sidewalk 16 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:21PM Pig B. Short -Tenn Operating Conditions Short-term operating conditions were assessed using total traffic which includes full development of Cherokee Flying Heights.

TRAFFIC IMPACTS In order to assess operating conditions with Cherokee Flying Heights fully operational, capacity analyses were conducted at the Taft Hill Road intersections with Mulberry Road, LaPorte Avenue and the site access. Total traffic (background traffic combined with site traffic) was developed. Total traffic is shown on Figure 6, Site traffic was rounded up to 5 vehicles for each traffic movement. This represents a very conserva- tive analysis. When carried to specific traffic movements at nearby intersections, 5 site vehicles were added to each potentially impacted traffic movement. Total traffic volumes were reviewed from an auxiliary lane standpoint. The results of this review are discussed in the following section. A. Auxiliary Lane Requirements Traffic movements at the site access to Taft Hill Road were reviewed. This effort focused on the need for a southbound right turn lane and a northbound left turn lane to accommodate vehicles entering the site. Both lanes were determined to be unwar- ranted using criteria presented in Report 279, "Intersection Channelization Design Guide" as published by TRB. Warrant sheets are presented in Appendix B. The Mulberry Road and LaPorte Avenue intersections with Taft Hill Road were not re- viewed. This was deemed appropriate given the negligible amount of site traffic expected to use these intersections (5 — 6 vehicles at each intersection during peak hours) and the apparent lack of right-of-way to implement any improvements. 13 FROM :GENE COPPOLA FAX NO. :303-792-5990 Rpr. 19 2002 12:21PM P16 LaPorte Site Drive Mulberry LEGEND: AM/PM 45/40 -0 220/175 —0- 135/175 0 N d NO ina�oto tom n 55130 — 4 340/225 ---► 75/75 NOTE: Rounded to nearest 5 vehicles, t 15/35 4--195/195 50/105 k— 40/70 4— 160/190 95/195 Figure 5 SNORT -TERM BACKGROUND 12 TRAFFIC FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:21PM P15 C. Trip Distribution Trip distribution is a function of the origin and destination of site users and the avail- able roadway system. In this case, all site traffic must use Taft Hill Road to access the site. Based upon current directional traffic on Taft Hill Road, a 50:50 directional split is appropriate in the northbound and southbound directions. V. FUTURE CONDITIONS A. Roadway Improvements The site is located in a built-up section of Fort Collins. Accordingly, no significant major roadway improvements are planned in the area of the site in the short-term. When and if improvements are made is largely speculative and cannot be reasonably predicted. For analysis purposes, any future improvements are assumed to occur well beyond the time frames considered in this study. B. Short -Term Background Traffic Volumes Background traffic was developed using an annual growth rate in the range of 11/ percent per year. This factor was applied to existing traffic volumes to approximate short-term conditions. Short-term conditions reflect the year 2005. This reflects the time frame requested by the City. By this time, Cherokee Flying Heights will be fully built and occupied. Short- term background traffic volumes are shown on Figure 5. 11 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:20PM P14 Q OOIfb1U Rttl-=•�... �a� �iQ7lllllfll I I �"� SSH 34 WAll i3lgiiH7 w�rar n... 10 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:20PM P13 IV. DEVELOPMENT ISSUES A. Project Description Cherokee Flying Heights is a residential development with 22 condominium/town- homes. It is expected that construction will start in 2000 with completion and full occupancy within the following year or two. A single full movement access to Taft Hill Road is planned to serve this development. A concept plan for this development is presented on Figure 4. B. Site Traffic Site traffic was estimated using Institute of Transportation Engineers (ITE) publication, "Trip Generation, 6th Edition", a nationally recognized reference. The condomin- ium/townhome classification was selected to best represent this development. Trips associated with Cherokee Flying Heights are indicated in the following table. Land Use size Daily AM Peak Hour PM Peak Hour Rate Trips Rate In Out Rate In Out Townhorne/Condominium 22 D.U. 5.86 129 0.44 2 8 0.54 8 4 As shown above, Cherokee Flying Heights is expected to generate 10 morning peak hour trips, 12 afternoon peak hour trips, and 129 trips per day. These trips are con- sidered minor. It should be noted that the current residential use on this site was not considered in the determination of site traffic. Accordingly, the amount of new site traffic will be less than that indicated above. 0 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:20PM P12 CURRENT OPERATING CONDITONS LEVEL OF SERVICE APPROACH/ INTERSECTION CONTROL AM PK HR PM PK HR MOVEMENT Taft Hill — Mulberry Street Signal EB C C WB C C NB C - C SB C C Per City standards, overall level of service'D' is defined as acceptable for arterial street intersections_ As shown above, all intersections currently operate at level of service'C' or better during peak hour periods.

Existing Road Network The Cherokee Flying Heights site is located along the west side of Taft Hill Road north of Mulberry Road. The address of the site is 105 South Taft Hill Road. Taft Hill Road is a minor arterial roadway having two lanes in each direction adjacent to the site. It is a north — south arterial roadway extending through the City of Fort Collins and beyond. Recent daily traffic on Taft Hill Road adjacent to the site is estimated at 10,500 vehicles per day. It typically has auxiliary lanes at all key inter- sections and on -street bicycle lanes. Older but functional sidewalk exists along the west side of Taft Hill Road. There are no driveways along the east side of Taft Hill Road in the area of the site, LaPorte Avenue and Mulberry Street intersect Taft Hill Road to the north and south of the site, respectively. These east — west minor arterial roadways lead to the down- town area. The Taft Hill Road intersections with these roadways are under traffic signal control. All streets are under Fort Collins jurisdiction. B. Surrounding Land Uses The Cherokee Flying Heights site is currently occupied by a less intense residential use. Residential developments lie directly north and south of the site with a golf course and cemetery to the east. The area is considered fully built. 4 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:19PM P7 II. AGENCY DISCUSSIONS Prior to undertaking this study, a scoping session was held with Eric Bracke. During that discussion, it was determined that an abbreviated transportation impact study was appropriate. Key items of agreement and direction are identified below. A full assessment of pedestrian, bicycle, and transit levels of service needs to be conducted. • The Taft Hill Road — Mulberry Street, Taft Hill Road — LaPorte Avenue, and site access intersections should be investigated. Weekday morning and afternoon peak hour conditions should be investigated. Other intersections are considered negligible. • An assessment of existing and future short-term conditions is appropriate. The short-term was identified as the year 2005. Traffic growth on nearby arterial streets of 1'/2 percent per year is reason- able to estimate future background traffic. • Mr. Bracke specifically asked that the Taft Hill Road — LaPorte Avenue in- tersection be fully investigated. Split phasing is under consideration at this intersection. The above items are included or addressed in the following sections of this report. 3 FROM :GENE COPPOLA FAX NO. :303-792-5990 Apr. 19 2002 12:19PM P6 9 N Wakon a Dr� Z b� W I `� a L0nc0r or. g N d w VV' Or • MOun in View ¢ x [ _ I 1 m cin 31 u hSC V....... z 2orry 2 Chen St .v a First :'d vi u Ma la `' a i 4 �u Y ¢ "he`Ct ._. `L PO 0 Aug , 7ill g T — � .. a m b �I � WMou ain Ave W Ob SI m s W Oak SI ..

INTRODUCTION Cherokee Flying Heights is a planned residential development along the west side of Taft Hill Road between Mulberry Road and LaPorte Avenue in Fort Collins, Colorado. A vicinity map is presented on Figure 1. This transportation impact study follows the established guidelines for such studies as are applicable and appropriate to the proposed project. The following key steps were undertaken as part of this study. Obtain current traffic and roadway data in the immediate area of the site. • Evaluate current operations to establish base conditions. Determine site generated traffic volumes and distribute this traffic to the nearby street system. • Estimate roadway traffic volumes for future conditions. • Evaluate operations with the Cherokee Flying Heights fully operational. • Inventory, evaluate, and assess the pedestrian, bicycle, and transit net- works serving the site. • Identify deficiencies and recommend measures to mitigate the impact of site generated traffic and enhance the alternate travel mode systems as appropriate. Key areas of investigation are documented in the following sections of this transporta- tion impact study.
