MEMORANDUM
TO: Jim Birdsall, Everitt Enterprises
Rusty McDaniel, Larimer County Engineering
FROM: Matt Delichf,Sp
DATE: February 9, 2000
SUBJECT: Fossil Lake PUD - Analysis of CR36/CR9 intersection
(File: 9750ME05)
At the request of Jim Birdsall, I have performed various
traffic engineering evaluations related to development of the Fossil
Lake PUD. I was requested to determine if it was possible to develop
Fossil Lake PUD, Filing 1 and Filing 2 (Phases 1 and 2) and the Swift
Addition with sole access.via CR9, south of CR36. This evaluation
required all site generated traffic to be directed through the
CR36/CR9 intersection. The site access to CR36 (located 1800 feet
east of CR9) would be completed with Fossil Lake PUD, Filing 2
(Phases 3 and 4).
Table 1 shows the trip generation from the portion of Fossil
Lake PUD and the Swift Addition that are included in this evaluation.
Trip Generation, 6th Edition, ITE was used as the reference for the
trip generation estimate. This site generated traffic was assigned
to the CR36/CR9 intersection and is shown in Figure 1.
Peak hour traffic was obtained at the CR36/CR9 intersection in
February 2000 and is shown on Figure 2. Raw data is provided in
Appendix A. By observation, this intersection operates acceptably.
The evaluation involved assigning traffic from known
development proposals (Harvest Park, Sage Creek, Celestica, Willow
Brook, etc.) to the CR36/CR9 intersection and then adding the
assigned traffic from the key portions of the Fossil Lake PUD (Figure
1). The total traffic is shown in Figure 3. Table 2 shows the
operation of this intersection with stop sign control on CR9.
Calculation forms are provided in Appendix B. This intersection will
operate acceptably with the traffic volumes shown in Figure 3. It
is recommended that all of the legs of this intersection be paved and
that the approach geometry shown in Figure 4 be provided at this
intersection.
It is concluded that the Fossil Lake PUD, Filing 1 and Filing
2 (Phases 1 and 2) can be built and occupied prior to completion of
the direct access to CR36 from the Fossil Lake PUD. It is expected
that this direct access will occur with the development of Fossil
Lake PUD, 2nd Filing (Phases 3 and 4).
