HomeMy WebLinkAboutPVH MEDICAL OFFICE BUILDING & PARKING STRUCTURE - PDP - 14-07 - SUBMITTAL DOCUMENTS - ROUND 1 - TRAFFIC STUDY (3)Lemay/Garfield Intersection
This T-intersection has stop sign control on the west leg of
Garfield Street. There is no east leg, since PVH (building) is east
of this intersection. The forecasted mid range left -turn volumes are
154 and 67, in the respective peak hours: The 95t" percentile queue
analyses indicate a queue length of 25 feet and 37 feet in the
respective peak hours. Using Figure 8-2 in LCUASS, the storage length
is 150 feet. Based upon available aerial photography, the existing
northbound left -turn lane is 145 feet plus bay taper (100 feet). The
southbound left -turn lane approaching Robertson (PVH Access) is 130
plus the coincidental bay.taper (100 feet). According to Figure 8-2
in LCUASS, the southbound storage (approaching .the PVH Access) is 50
feet plus bay taper. This analysis indicates that the southbound
left -turn lane is "over -sized." This segment of Lemay Avenue,could be
restriped, providing more northbound left -turn storage.
Alternatively, this segment of Lemay Avenue could be restriped with a
two-way left -turn lane, which would be "self-regulating." In either
case, there will be adequate left -turn storage for. the left turns on
Lemay Avenue.
It is concluded that there is/will be adequate room to store the
left turns on Lemay Avenue approaching Doctors Lane (northbound) and
approaching Garfield Street (northbound). Do not hesitate to contact
me if you have questions or desire additional information.

MEMORANDUM
TO: Angie Milewski, BHA Design
Marcia Lester, Davis Partnership
Ward Stanford, Fort Collins Traffic Operations
FROM: Matt Delich�
DATE: June 25, 2007
SUBJECT: Expansion .of the, PVH :Lemay Campus Transportation Impact
Study - Response to staff comments (File: 0692MF01)
This. memorandum addresses comment number 55 .regarding the
northbound left -turn queue lengths by Ward Stanford, Traffic
Operations. Specifically, additional/alte'rnative analyses were
requested for the northbound left -turn lanes on Lemay Avenue
approaching Garfield. Street .and Doctors Lane (proposed Parking
Garage). The analyses used the traffic volumes shown on Figure 13
(Mid Range (2013) Total Peak Hour Traffic), as contained in the
"Expansion of the. PVH Lemay Campus Transportation Impact Study," May
2007. The alternative analyses evaluation used Figure 8-2 from the
"Larimer County Urban Area Street Standards" (LCUASS).
Lemay/Doctors Intersection_
This intersection is signalized. It will be one of the accesses
to the proposed parking structure. The forecasted mid range left -turn
volumes are 137 and 70, in the respective peak hours. The 951h
percentile queue analyses indicate a queue length of. 32 feet and 47
feet in the respective peak hours. Using Figure.8-2 in LCUASS, the
storage length is 140-190 feet (minimum -desirable).. Based upon
available aerial photography, the existing northbound left -,turn lane
is 90 feet plus bay taper (60 feet). The distance from the start of
the bay taper to the projection of the north curb of Garfield Street
is 45 feet. If the center lane were restriped as a continuous
northbound left -turn lane, the storage requirement, as calculated
using LCUASS, could be accommodated in this area. There will not be
any conflicting southbound left turns, since there is .no east leg at
the Lemay/Garfield intersection. It is concluded that there is/will
be adequate northbound left -turn storage .approaching Doctors. Lane
(Parking Garage).
