To: Martina Wilkinson, City of Fort Collins
From: Ruth Rollins
Date: March 6, 2020
Subject: Supplemental Traffic Study – Proposed Haven Apartments
The following memorandum provides a supplemental transportation analysis of the proposed
Haven Apartments located at 730 W Prospect Road in Fort Collins. The original study was
documented in a memorandum to Martina Wilkinson dated August 28, 2019. The original study
concluded that the additional 54 apartments would not have significant transportation impacts.
The project has been modified. The parking for the 54 units was originally proposed to be
housed on-site. This design has been changed, parking for 50 units will be provided at the
existing Apex Apartments located directly west of the proposed project. This revision is illustrated
on Figure 1.

Primary vehicular access to the project site will now be from the Apex Apartments driveway
located at 808 W Prospect Road. This driveway is designed as a right-in/right-out only.
The City requested that this driveway be analyzed to look at peak hour operations and determine
the need for auxiliary lanes.
EXISTING CONDITIONS AT APEX DRIVEWAY
Peak hour turning movement counts were performed at the Apex Driveway on March 3, 2020
during both the morning (7:00 to 9:00 AM) and evening (4:00 to 6:00 PM) peak hours. The
results of this data collection are provided in the Appendix A and shown below on Figure 2. The
owner of the Apex Apartments indicated that 60 of the 61 units are rented, and therefore these
counts represent an essentially fully occupied building.
It should be noted that there was construction directly west of the driveway and one of the
westbound lanes on Prospect was closed. These counts were compared to the volumes
originally documented in the August 28, 2019 memo. It does not appear that the closure of the
lane on Prospect had a significant impact on traffic volumes.

TRAFFIC OPERATIONS AT APEX DRIVEWAY
The existing operations at the access drive were evaluated for the peak hours. Transportation
professionals evaluate intersections to determine how they are currently operating and will
operate in the future. The methods employed can be found in the Transportation Research
Board’s, 6th Edition, 2016 Highway Capacity Manual (HCM). Level of service (LOS) is based on a
“graded” system from LOS A, very little to no delays to LOS F which represents excessive delays
and congestion. A description of the level of service values is provided in Table 1.
The intersection operations thresholds for acceptable level of service are provided in the Larimer
County, Urban Area Street Standards (LCUASS), most recently updated September 19, 2016.
For an Arterial/Local unsignalized intersection, the overall threshold is LOS D and for an
approach leg is LOS F.

The results of the intersection operations analysis at the Apex driveway, are provided in Table 2.
As shown, all movements and the overall intersection, operate acceptably. It should be noted
that some left-turns (that are prohibited) were observed during both the morning and evening
peak hours and were included in this analysis. The detailed worksheets are provided in Appendix
B.

RELOCATED PROJECT TRIPS
The trip generation of the proposed project was determined based on rates that were developed
by the City of Fort Collins for student housing. The rates and associated trips are provided in
Table 3. The trips were estimated for 50 apartment units (the units that will have parking in the
Apex lot). As shown the 50 units will generate approximately 135 daily, 10 morning and 21
evening peak hour trips. The resulting peak hour trips at the Apex driveway are illustrated on
Figure 3.

SHORT RANGE TRAFFIC
The future traffic on Prospect Road at the Apex driveway was determined for the Year 2021, the
anticipated completion for the Haven Apartments. The background traffic for 2021 was based on
the following three elements:
• The 2020 counts were factored upward by one percent to account for overall growth.

• Traffic from two nearby projects was added to the base traffic volumes. These projects
are: 821 W Lake Street Apartments, and The Standard. Trips associated with these
projects were obtained from their respective Traffic Impact Studies.
The resulting Background Short Range Traffic (without the Project) are provided on Figure 4.

The Total Short Range traffic projections were developed by adding the project traffic depicted on
Figure 3 to the Background traffic shown on Figure 4. The Total Short Range traffic is shown on
Figure 5.

SHORT RANGE TRAFFIC OPERATIONS AT APEX DRIVEWAY
The results of the intersection operations analysis at the existing Apex driveway for both Short
Range background and total traffic conditions are shown in Table 4. As shown in the table, the
intersections movements and overall operations are projected to operate at acceptable levels. It
should be noted that the SB left-turn/right-turn improves under Total traffic conditions. This is due
to an increased number of right-turns which have better operations than the prohibited left-turns

AUXILIARY LANE ANALYSIS
An analysis was conducted to determine the need for an auxiliary right-turn lane on Prospect
Road at the Apex driveway. The right-turns depicted on Figure 5 were analyzed based on the
guidelines set forth in the Larimer County Urban Area Street Standards, in Chapter 8. The speed
limit on Prospect Road is 35 mph. The guidelines are provided in Appendix C.
As shown earlier on Figure 5, under total traffic conditions, the highest westbound right-turn
volume is 22 vehicles, during the PM peak hour, with both the Apex and proposed Haven
Apartments traffic accounted for. The minimum threshold for a right-turn lane at 35 mph and an
approach volume of 1,322 vehicles is 40 vehicles per hour. Based on the standards, a
westbound right-turn lane is not warranted.
CONCLUSIONS
The relocation of parking for the proposed Haven Apartments to the Apex Apartments parking lot
will not have any significant impacts to the transportation system. A westbound right-turn lane
from Prospect Road to the Apex driveway is not warranted.
