The site location is shown in Figure 1. The site plan for the Van Horn Townhomes is shown in Figure 2. The Van Horn Townhomes is proposed as 26 townhome dwelling units. The access to the site will be to/from Blondel Street. The scape of this TIS was discussed with Steve Gilchrist, Fort Collins Traffic Engineering. Since the trip generation is so low, this TIS will provide trip generation and multi-modal level of service analyses. Suniga Road is classified as a four-lane arterial street on the Fort Collins Master Street Plan. Currently, Suniga Road has a four-lane cross section with a raised center median. The posted speed is 40 mph. There are separated, raised bicycle lanes on Suniga Road, west of Blue Spruce Drive-Blondel Street. Suniga Road has on-street bicycle lanes to the east of Blue Spruce Drive-Blondel Street. The Suniga/Blue Spruce- Blondel intersection has stop sign control on Blue Spruce Drive-Blondel Street. The existing geometry at the Suniga/Blue Spruce-Blondel intersection is shown in Figure 3. Recent peak hour vehicle counts at the Suniga/Blue Spruce-Blondel intersection are shown in Figure 4. Also shown on Figure 4 are recent peak hour pedestrian and bicycle counts. Raw traffic data is provided in Appendix A. Using the volumes shown in Figure 4, the current peak hour operation at the Suniga/Blue Spruce-Blondel intersection is shown in Table 1. Calculation forms for these analyses are provided in Appendix B. The intersection was analyzed using the unsignalized intersection techniques from the Hiqhwav Capacitv Manual, 6t" Edition. A description of level of service for unsignalized intersections from the Hiqhwav Capacitv Manual, 6t" Edition and the Motor Vehicle LOS Standards (Intersections) are provided in Appendix B. Acceptable operation is considered to be at level of service D overall and level of service F for any approach leg at unsignalized intersections. As can be seen in Table 1, the Suniga/Blue Spruce-Blondel intersection is currently operating acceptably with existing control and geometry. Trip generation is important in considering the impact of a development such as this upon the existing and proposed street system. A compilation of trip generation information contained in Trip Generation, 11th Edition, ITE was used to estimate trips that would be generated by the proposed/expected uses at the Van Horn Townhomes site. Single Family Attached Housing [Townhome] (Code 215) was used to estimate the trip generation of the 26 dwelling units. Table 2 shows the expected trip generation to/from the site on a daily and peak hour basis. A trip is defined as a one-way vehicle movement from origin to destination. The trip generation resulted in 188 daily trip ends, 12 morning peak hour trip ends, and 15 afternoon peak hour trip ends. Also shown on Table 2 is the peak hour trip generation for pedestrians and bicycles. Figure 5 shows the recent plus site generated peak hour traffic for vehicles, pedestrians, and bicycles. Since the recent pedestrian and bicycle counts were done during the winter, pedestrian and bicycle trip generation for the Blondel Street neighborhood was calculated based upon Trip Generation, 11t" Edition, ITE and the number of dwelling units near Blondel Street. Pedestrian Level of Service Figure 6 shows a map of the area that is within 1320 feet of the Van Horn Townhomes site. The Van Horn Townhomes site is located within an area termed as "Pedestrian District," which sets the level of service threshold at LOS A for all measured factors, except for Street Crossings which is LOS B. There will be six pedestrian destinations within 1320 feet of the Van Horn Townhomes site. These are: 1) the commercial uses to the northwest of the site, 2) the residential uses to the north of the site, 3) the residential uses to the northeast of the site, 4) the residential uses to the south of the site, 5) the commercial uses to the west of the site, and 6) the commercial uses to the west of the site across College Avenue. There are sidewalks along all streets in the area of the Van Horn Townhomes site. Sidewalks will be built within the development that will connect to existing nearby sidewalks along Blondel Street and Suniga Road. The Pedestrian LOS Worksheet is provided in Table 3. • Directness — The distance ratio to all pedestrian destinations is less than 1.2 (LOS A) using the existing sidewalk system. • Continuity — The sidewalk system to all destination areas has no breaks or gaps. All sidewalks in the area are separated with landscaped parkways. Therefore, continuity to all destination areas can achieve LOS A. • Street Crossings — There are only minor (local) street crossings for destinations #4 and #5. There is/will be a signalized crossing at the College/Suniga intersection to get to destination #6. In order to get to destination #1, #2, and #3, it requires a crossing of Suniga Road (major street). Therefore, the Crosswalk Treatment Identification Process was used for the crossing of Suniga Road. In the "Fort Collins Active Modes Plan," the Suniga/Blue Spruce-Blondel intersection was identified as a"Low Priority/Readiness Project" for signs and markings. Using the Crosswalk Treatment Identification Process, this location is adjacent to a major pedestrian generator/attractor. The nearest marked or protected crosswalk is �� LDELICH Van Horn Townhomes TIS, April 2024 � � rASSOCIATES Page 2 greater than 300 feet away (College/Suniga intersection). The volume of pedestrian generator/attractor. The nearest marked or protected crosswalk is greater than 300 feet away (College/Suniga intersection). The volume of pedestrians crossing Suniga Road will be less than 40 per hour or less than 120 in four hours. Therefore, no crossing treatment is required at the Suniga/Blue Spruce-Blondel intersection. Visual Interest and Amenity — The visual interest and amenity will be acceptable at LOS A for all destination areas, since this area generally has enhanced pedestrian features (large sidewalk widths, landscaping, etc.). Security — The security will be acceptable at LOS A for all destination areas, since this area generally has enhanced pedestrian features. There is street lighting and very adequate sidewalks along Suniga Road. Bicycle Level of Service Figure 7 shows a map of the area that is within 1320 feet of the Van Horn Townhomes site. There will be three bicycle destinations within 1320 feet of the Van Horn Townhomes site. These are: 1) the commercial uses to the northwest of the site, 2) the commercial uses to the west of the site, and 3) the commercial uses to the west of the site across College Avenue. The Bicycle LOS Worksheet is provided in Table 4. The level of service is A for the bicycle destinations, since the site is directly connected to bicycle lanes on Suniga Road. There are separated, raised bicycle lanes on Suniga Road, west of Blue Spruce Drive-Blondel Street. Suniga Road has on-street bicycle lanes to the east of Blue Spruce Drive-Blondel Street. This is consistent with the information contained in the "Fort Collins Active Modes Plan." Bicycle lanes are not required on Blondel Street or Blue Spruce Drive since these are local streets. Transit Level of Service Currently, this area of Fort Collins is served by Transfort Routes 8 and 81. Route 8 operates from the Downtown Transit Center and along College Avenue, Willox Lane, Blue Spruce Drive, Conifer Street, Redwood Street, and Linden Street. Route 81 operates a loop similar to that of Route 8. The nearest bus stop is at the Redwood/Cajetan intersection, approximately 1,685 feet from the Van Horn Townhomes site. It is concluded that all modes of travel (vehicle, pedestrian & bicycle) will achieve acceptable levels of service. A crosswalk treatment at the Suniga/Blue Spruce-Blondel intersection is not required. �� LDELICH Van Horn Townhomes TIS, April 2024 � � rASSOCIATES Page 3 SCALE: 1 "=1000' SITE LOCATION �� -DELICH � � rASSOCIATES Figure 1 Van Horn Townhomes TIS, April 2024 Page 4 � N SCALE: 1 "=50' � 15 R�,Gn' CF tYF� ?ER PLi.i, (61' TRAVEIED WAY) S��E Nig.�[c �'�n � � . i'�H[i: �..
