The south bound transit service does not have a continuous sidewalk connection currently available. Street Crossing B/C: Although there are no major streets to cross to get to the east side of College Avenue and the northbound transit stop on College Avenue, a pedestrian will need to cross College at Fossil Creek to utilize the southbound transit stop. A pedestrian button exists at the intersection, along with adequate lighting, and painted crosswalks for all movements. Visual Interest & Amenity B/C: The landscaping in the area is generous and attractive. This project proposes to extend the sidewalk along the east side of Snead Drive adjacent to this parcel. _, Security B: Pedestrian line of sight and visibility is good. The existing lighting along the direct route to the north bound transit stop is good. This, along with the other street lamps and parking lot lighting in the area provides adequate lighting. However, evening activities are limited and may provide a less than desirable feeling of security after closing time of the nearby shopping centers and offices. This should improve as the area continues to develop. Bicycle LOS - C Currently there is a north/south bike ane on College Avenue which connects with the Harmony East/West Route. The bicycle connection to College Avenue is via Fairway Lane or Fossil Creek Parkway. Transit LOS - B The Fox Trot transit service along College Avenue could be used by employees and visitors of the Fort Collins/Loveland Water District Office. This service currently runs at one-half hour intervals from approximately 6:30am to 6:30pm, between downtown Loveland and the Square in Fort Collins. Based on City of Fort Collins 2015 transit forecasts, College Avenue will be a High Frequency Travel Corridor that will provide transit service every 20 minutes for twelve hours per day and an additional 4 hours of evening service. Balloffet & Associates, Inc. 16 Fort Collins / Loveland Water District Traffic Impact Study The year 2000 short range and year 2015 long range background plus project a.m. and p.m. peak hour level of service analysis is presented in Table C. As can be seen, the volumes generated by the proposed Fort Collins/Loveland Water District Office are insignificant and will not directly result in any unacceptable levels of service. However, as seen in Table A the`year'2015 pm peak background traffic causes the intersection to 'drop below the minimum level of service that is acceptable. Traffic improvement miIitations may be necessary if these projected traffic volumes are realized. The traffic mitigation improvements that improved the level of service to an acceptable level of service in Table A was the addition of dual westbound left turn lanes.

Balloffet & Associates, Inc. 10 Fort Collins / Loveland Water District Traffic Impact Study All intersection turn movements will operate acceptably during . the short range year 2000 background conditions. However, the long range 2015 background conditions operate below the required City of Fort Collins standards. Based on a review of the Level of service analysis, an acceptable level of service can be' achieved with the conversion of the west bound through lane to a second west bound left turn lane, and the right turn lane' converted to a through/right turn lane.' It shall be noted that this 2015 forecast is contingent upon connecting Fossil Creek between College Avenue and Lemay Avenue. Project Traffic Trip generation for the proposed Fort Collins/Loveland Water District Office, are based on estimates form The ITE fifth addition trip generation manual. Based on six trips per employee, the 19 employees will generate approximately 114 daily trips. Morning and afternoon peak counts are also based on the ITE fifth addition trip generation manual. Based on visitor count history at other facilities of this type. This development will generate approximately 17 visitor trip ends per day, with some of these trips occurring during the p.m. peak hour. Conservatively estimated counts for service vehicles indicate approximately one service vehicle trip end per day for this type of facility.

In general, traffic flows reflect inbound and outbound employees arrival and departure patterns. The trip distributions for the proposed project are based on the location of the project within the City of Fort Collins, the current trip distribution patterns, and on the projected growth rates estimated for the year 2015. Based on this information, it was estimated that approximately 65 percent of the project traffic would go north on College and 35 percent south, for the year 2000, and 55 percent Balloffet & Associates, Inc. 0 Fort Collins - Loveland Water District Traffic Impact Study Figure 5 -Year 2015 Long Range Background Peak Hour Traffic Volumes Legend - 47/144 AM/PM Peak Hour UN Balloffet & Associates, Inc. 8 Fort Collins - Loveland Water District Traffic Impact Study Figure 4 -Year 2000 Short Range Background Peak Hour Traffic Volumes Legend 47/144 AM/PM Peak Hour CO N U) Q m IM m O U Fairway Ln. a Project Location o 0 a N �125/83 ips eve i (�s/ao 10/221 1 it 2/14­1� 14/40 N Fossil N Ridge Dr. 0 ;p °tea Of A� FBovgr.odr 4.16.98 Balloffet & Associates, Inc. 7 Fort Collins / Loveland Water District Traffic Impact Study I Table A - Level of Service Calculations Level of Service College/Fossil Creek (signalized) AM PM Existing Intersection Level of Service --B-- B _ As can be seen above, acceptable levels of services exist for both the a.m. and p.m. peak hour conditions for all movements of the College Avenue / Fossil Creek Parkway intersection.

A direct pedestrian connection exists to College Avenue via an east/west sidewalk through the Fossil Creek Design. Attached sidewalks exist along Snead Drive and Fairway Lane providing an alternative pedestrian access to College Avenue . Bike lanes are also accessible along College Avenue. ' Existing Traffic The limits of this study are based on discussions with Eric Bracke, the City of Fort Collins Traffic Engineer. Based on the minimum anticipated traffic volumes generated by this project, it was concluded that the focus of the study should be at the intersection of College Avenue and Fossil Creek Parkway. Existing a.m. and p.m. peak hour intersection traffic counts for the College Avenue/Fossil Creek Parkway intersection were conducted for this project consistent with the Traffic Impact Study Guideline. The counts were collected by Balloffet & Associates on April 4-5, 1998. The existing a.m. and p.m. peak hour intersection turn movement counts for College Avenue/ Fossil Creek Parkway intersection are presented in Figure 3. 01' An existing a.m. and p.m. peak hour intersection level of service analysis was performed for the College Avenue/Fossil Creek '•" Parkway intersection. Level of Service (LOS) is a grading system as to how well an intersection operates, ranging from "A," which is excellent, to "F" for a failure. LOS of "D" or better is the City of Fort Collin's threshold for being acceptable. The existing levels of service for this intersection is based on the Highway Capacity Manual and are presented in Table A.

Horsetooth Rd. r- CO N U) M E 4'J, Balloffet &Associates, Inc. 2 flk� . . � Fort Collins / Loveland Water District Traffic Impact Study Introduction The following traffic impact study is for the Fort Collins/Loveland Water District Office,proposed to be located at the end of Snead Drive north of Fossil Creek Parkway, and east of College Avenue in the City of Fort Collins. The analysis evaluates the existing conditions, short-term year 2000 forecast impacts, and the long-term year 2015 forecast impacts. This analysis examines automobile, transit, bicycle and pedestrian mobility. Due to the minimum trip generation from the proposed Fort Collins/Loveland Water District Office, the focus 'of this study' is at the intersection ""of College Avenue and Fossil Creek Parkway. As will be presented, the proposed project will not result in a significant traffic impact, and the available pedestrian, bicycle, and transit facilities are adequate. Access to College Avenue will be via Fairway Lane and Fossil Creek Parkway through a public access easement through the Fossil Creek Design Center located east of Snead Drive. Ultimately Snead Drive will be extended to the south and connect with Fossil Creek Drive. This will occur with the development of the vacant parcel south of this proposed project. Existing Setting The proposed project will have access drives connecting to Snead Drive, and Fossil Creek Parkway in the City of Fort Collins, as presented in the project location map (Figure 1). Snead Drive is a two-lane commercial/light industrial street that intersects with Fairway Drive to the north. Fairway Lane is a two-lane facility at its intersection with Snead Drive. Fossil Creek Parkway is a two lane residential collector with a rural cross section. The cross section for College Avenue at the intersection of Fossil Creek accommodates left turn lanes, two through lanes in each direction and designated right turn lanes. The speed limit along College Avenue is 50 miles per hour. Ultimately Fossil Creek will be connected to the east and provide through access to South Lemay Avenue The intersection of Fossil Creek Parkway and College Avenue is controlled by a signal. All other intersections within the study area are stop sign -controlled for the minor cross street. Project Description The Fort Collins/Loveland Water District Office, is a public agency that will employ 19 people. Nine will work in field operations, and the other ten are administrative. This facility will have a storage area for materials, and a drive through payment drop for the r convenience of their senior and handicap costumers.
