1.0 Project Description
The Vail Marriott Residence Inn, a proposed 1.9 acre redevelopment, is located near
the intersection of the Interstate 70 North Frontage Road and Buffehr Creek Road
within the Town of Vail. The proposed project will replace the former Roost Lodge
that was located on the property.
The southern boundary of the property abuts the Frontage Road and starts
approximately 250 feet north east of the Buffehr Creek Road intersection with the
Frontage Road. The property is also bordered on the north by Meadow Ridge Road,
but is does not and is not anticipated to take access from it due to the grade
differential. The location of this property in relation to the surrounding area can be
seen in Figure 1.
This site was previously approved for redevelopment.
Figure 1: Area Map

The proposed redevelopment is expected to include a Marriott Residence Inn, it’s
associated support facilities and deed restricted, local employee, long‐term rental
units.
Specifically, the Vail Marriott Residence Inn project is currently anticipated to consist
of:
170 Hotel Rooms
Lobby, Library, Lounge and Associated Guest Facilities
113 Long‐Term Rental Local Employee Housing Units
A concept plan of the proposed development can be seen in Figure 2.
The site was formerly occupied by the Roost Lodge, which included a 72‐room hotel
and 1 employee housing unit. The Roost Lodge was demolished in 2014 and the site
is now vacant.
The Vail Marriott Residence Inn redevelopment has an assumed build out completion
year of 2018. Analysis has been performed for existing conditions, background and
total conditions for short‐term Year 2018 as well as for the long‐range planning Year
2040.
1.1 Previous Traffic Analysis
This site has been previously proposed for redevelopment that was not constructed.
In 2013, The Vail Marriott Residence Inn was planned to include 176 Hotel Suite
Rooms and 2 Employee Housing Units. This development was studied in McDowell
Engineering’s Transportation Impact Study for Marriott Residence Inn Redevelopment
dated May 21, 2013. This study was previously approved by CDOT and the Town of
Vail.

2.0 Existing Conditions
2.1 Description of Existing Transportation System
Interstate 70 North Frontage Road:
The I‐70 North Frontage Road provides
the primary local connection along the
north side of Interstate 70 between the
West Vail and Vail Village Interchanges.
In the vicinity of the project site, this
two‐lane facility is classified as Access
Category F‐R, Frontage Road by the
Colorado Department of
Transportation (CDOT) and has a
posted speed limit of 35 mph. There
are no existing auxiliary turn lanes at
the two accesses to the property.
CDOT and the Town of Vail completed an Access Management Plan Map for this
roadway as part of their Vail Transportation Master Plan Update in 2009.
Buffehr Creek Road: Buffehr Creek Road is a local two‐lane roadway providing access
to Chamonix Lane and residential development north of the development property.
Buffehr Creek Intersects the North Frontage Road 250 feet to the southwest of the
development property. The posted speed limit on this roadway is 25 mph.
Meadow Ridge Road: Meadow Ridge Road is a short, cul‐de‐sac roadway that forms
the northwest boundary of the proposed redevelopment. The subject property does
not take access from Meadow Ridge Road, nor is it expected to do so in the future
due to the grade differential between the property and the road.
Pedestrian, Transit and Bicycle Facilities:
The sole existing bicycle/ pedestrian
facility in the vicinity of the Vail
Marriott Residence Inn redevelopment
is the North Recreation Path, which
connects the Vail Village and West Vail
Interchanges along the north side of
the North Frontage Road. The path is
contiguous across the frontage of the
site and consists of a widened asphalt
shoulder. A concrete path with curb
and gutter exists to the east of the
project site and west of Buffehr Creek
Road.
M1234 Vail Marriott Residence Inn Redevelopment August 5, 2016 Page

Both the Red and Green West Vail bus
routes travel along the North Frontage
Road adjacent to the redevelopment
site. There is a bus stop for the
westbound routes at the southwest
corner of the property.
Year 2018 Background Traffic Volumes: Year 2018 traffic conditions are based on
2013 traffic counts provided by the Town taken at the intersection of the North
Frontage Road and Buffehr Creek Road. These 2013 counts were compared to the
from Figure 15: Year 2025 Peak Hour Projections of the Vail Transportation Master
Plan Update, 2009 at the intersection of the North Frontage Road with Buffehr Creek
Road (Intersection Number 22). Refer to the Appendix for this data and
correspondence with CDOT and the Town of Vail.
The assumed Year 2018 Background Volumes were derived from a linear interpolation
between Years 2013 and 2025 as the starting and finishing years, respectively. Per
Town staff, there are no other development projects that should impact these
volumes. Background evening volume projections for Year 2018 can be seen in Figure
3.

3.0 Future Traffic Projections
3.1 Capital Improvement Projects
Per the Vail Transportation Master Plan Update, 2009 (Master Plan Update), the
North Frontage Road is anticipated to remain a two‐lane facility through the long term
planning horizon. However, the Master Plan Update anticipates the construction of
an eastbound left turn deceleration lane to Buffehr Creek Road prior to Year 2035.
The Town of Vail and CDOT have begun construction on the Simba Run Underpass of
I‐70 as anticipated by the Master Plan Update. The project is anticipated to be
completed by December 2017. This underpass, is located to the west of the Lionshead
Village and will provide an additional connection between the parts of Vail north of I‐
70 and those south of the interstate. Per the Master Plan Update, the likely result of
this underpass on project‐generated traffic would be to increase the portion of traffic
headed to or from the east on the North Frontage Road.
3.2 Background Traffic Growth
Long‐term background growth along the North Frontage Road is based on the Year
2025 volume projections provided in the Master Plan Update. Correspondence with
Town staff regarding the anticipated growth rates can be found in the Appendix. Per
Town staff,
…these projections represent a build out scenario study with 2025 selected
as full build out. This was done during the boom in Vail and a lot of large
developments were on the table going thru the process. Many of those have
been stopped or delayed. We suggest using the 2025 data with a modest
growth rate of 0.5% from 2025 to 2035.
This methodology was used for Year 2040 conditions. The resulting projected Year
2040 background traffic volumes with the addition of the Simba Run underpass
volumes can be seen in Figure 4.

4.0 Project Traffic
4.1 Trip Generation
The proposed Marriott Residence Inn is anticipated to consist of:
170 Hotel Rooms (all with kitchens)
o Lobby, Library, Lounge and Associated Guest Facilities
113 Long‐Term Rental Local Employee Housing Units
10 Condos located on adjacent parcel
100 Space Parking Club (leased parking spaces)
A trip generation analysis was prepared based on ITE’s Trip Generation Manual data
for the following land uses:
#310, Hotel
#223, Mid‐Rise Apartment
#230, Residential Condo/Townhome
The Parking Club use does not fit into an established trip generation land use within
the ITE Trip Generation Manual
The proposed additional parking spaces are anticipated to generate additional vehicle
trips to and from the parking structure. ITE publishes national parking rates and trip
generation rates for specific land uses. These rates were used to compare the number
of parking spaces to the associated number of additional vehicle trips. Per their 2010
Parking Generation Manual, 4th Edition7; a hotel requires 1.54 parking spaces per
hotel room. Working backwards from the 85th percentile parking rate, the additional
100 parking spaces would adequately serve 65 hotel rooms. ITE’s anticipated trip
generation rates (per ITE’s 2012 Trip Generation Manual, 9th Edition) for 65 rooms is
0.52 trips per room in the morning peak hour, 0.40 trips per room in the evening peak
hour, and 0.47 trips per room during the Saturday peak hour.
Because it is anticipated that these leased parking spaces would primarily be used for
skier parking the Inbound / Outbound distribution from Land Use #466, Snow Ski Area
was used for trip distribution.
The hotel land use also accounts for ancillary land uses such as the lobby, library and
lounge for guests.
Based on the Trip Generation Manual and the assumptions made, this site would be
expected to generate a total of 228 Saturday peak hour trips, 178 morning peak hour
trips, and 207 evening peak hour trips, including all modes of travel. Refer to Table 1
for trip generation calculations and further breakdown of these trips.

4.2 Trip Distribution
The distribution of project‐generated vehicular traffic on adjacent roadways is
influenced by several factors including the following:
The location of the site relative to other commercial facilities and the roadway
network.
The configuration of the existing and proposed adjacent roadway network
Relative location of neighboring population centers
Based upon the above factors and the current completion date of December 2017 for
the Simba Run underpass, it is assumed that approximately fifty percent (50%) of site
generated traffic will travel to or from the east on the North Frontage Road and fifty
percent (50%) will travel to or from the west on the North Frontage Road under short
term conditions.
4.3 Site Circulation
The Transportation Master Plan and Access Management Plan Map provide guidance
for the access points to the subject property. These documents specify that the
easternmost access will be ingress only and the westernmost access will be egress
only.
As designed, the site is anticipated to operate most effectively with the easternmost
access as ingress only and the westernmost access as a full movement. Because the
site will include hotel as well as long‐term rental housing it is believed that site access
would operate most efficiently with this configuration. The easternmost access would
be used for hotel check‐in, shuttles, and deliveries. The westernmost access would
be the primary access for the apartments, parking garage, and hotel guests after
check‐in. The Town of Vail has indicated that they would support this change from
the Access Management Plan if the access points operate adequately as proposed. It
is understood that CDOT would need to also support this change and that the Access
Management Plan would need to be updated to reflect the change.
Per Section 4.4(1) of the State Highway Access Code, 2002, (Access Code) the
minimum distance between access points should be at a minimum equal to the design
sight distance along the highway. Given a 35 mph posted speed limit on the North
Frontage Road, the access points should be a minimum of 250 feet apart.
Access to the adjacent parcel is approximately 120‐feet west of the proposed
westernmost access to the site. The Access Management Plan anticipates that the
adjacent access to the North Frontage Road would be closed when this parcel is
redeveloped in the future and access would be from Meadow Ridge Road.
Alternately, if acceptable the adjacent property owners, access to the site could be
from the westernmost access to the Vail Marriott site allowing closure of the existing
M1234 Vail Marriott Residence Inn Redevelopment August 5, 2016 Page
15
access. If the accesses are not combined, a CDOT Design Waiver would be required
for the Access Spacing.
4.4 Trip Mode Split and Assignment
Given the available bicycle/pedestrian routes and adjacent transit stop for the local
bus system, it can be assumed that a portion of site generated trips will be made by
modes other than passenger car. The limited parking in Vail also encourages people
to use alternative modes of transportation. An assumed multimodal reduction of ten
percent (10%) would result in the reduction of the volume automobile trips by 23 trips
during the Saturday peak hour, 17 trips during the weekday morning peak hour and
20 trips during the weekday evening peak hour.
Following the removal of non‐vehicular trips from the project generated traffic, the
anticipated volume of vehicular trips at each site access can be calculated. The
anticipated assignment of trips on the roadway system is determined by applying the
external trip generation expected for this site and its corresponding mode split to the
estimated trip distribution. The resulting projections of site generated traffic with the
Simba Run underpass can be seen in Figure 6.
The Year 2018 total traffic anticipated at each intersection in question is the sum of
the estimated Year 2018 background traffic (Figure 3) traffic with Figure 6, and can be
seen in Figure 7.
Similarly, Year 2040 total traffic is the sum of Year 2018 background traffic (Figure 3)
traffic with Figure 4, and can be seen in Figure 8.
As only evening peak hour data was available from the Master Plan Update, all
volumes in Figures 7 and 8 only represent the evening peak hour.

5.0 Transportation Impact Analysis
5.1 Site Access Auxiliary Turn Lanes
As the North Frontage Road is a State Highway facility of Access Category F‐R,
Frontage Road (Speed Limit 35 mph), the need for auxiliary turn lanes to and from the
site should be addressed. Per Section 3.13(4)(c‐d) of the State Highway Access Code,
2002 (Access Code), as the North Frontage road has a posted speed less than 45 mph,
acceleration lanes are generally not required and were not assessed further.
At the proposed eastern and western site accesses there is the potential for two
auxiliary deceleration lanes, the eastbound left and westbound right movements.
Neither lane currently exists at either access location.
Right Turn Deceleration:
A westbound right turn deceleration lane is required on a facility of this type when
the anticipated peak hour volumes exceed 50vph. Anticipated right turn volumes
entering the eastern and western site accesses range from 14‐20vph and 33‐47vph
respectively. The volume range is given because the traffic volume is expected to vary
over the morning, evening and Saturday peak hour traffic.
The Saturday peak hour volume for the western site access is on the threshold of the
CDOT warrant but does not exceed the requirement. The AM and PM peak hour
volumes do not CDOT’s threshold at either location. Based on these volumes no
westbound right turn lane should be required at either site access.
Left Turn Deceleration:
An eastbound left turn deceleration lane would be required if peak hour volumes
expected to use this movement exceed 25vph. Anticipated left turn volumes entering
the eastern and western site accesses range from 14‐20vph and 33‐47vph
respectively. Peak hour volumes for the AM, PM, and Saturday are projected to
exceed the CDOT threshold and at the eastbound left ingress movement at the
western site access. A deceleration lane will be required at this location. Refer to Table
2, Auxiliary Turn Lane Requirements for a breakdown of expected conditions.

The Access Code also details the required auxiliary turn lane lengths. Per Section 4,
the auxiliary eastbound left lane should consist of a 10:1 taper and 46 feet of storage,
for a total distance of 166 feet.

5.2 Level of Service Analysis
An HCM 2010 site access analysis was performed for both short term Year 2018 and
long term Year 2040 conditions. This analysis assumes that the single deceleration
lane explored as part of Section 5.1 will be constructed. The western full‐movement
access was anticipated to have both left and right turn lanes. Table 4 summarizes the
total level of service (LOS) and delays.

East Site Access and No Control EBL/T A (0) A (0)
(Ingress Only) No Control WBR/T A (0) A (0)
As can be seen in Table 4, the eastern site access is anticipated to operate
satisfactorily following the completion of the redevelopment through the long term
planning horizon.
The western site access is anticipated to operate at an acceptable LOS through the
Year 2018. By Year 2040 evening peak hour traffic volumes will deteriorate to
unacceptable levels of service for the southbound left turn movement due to high
volumes on the North Frontage Road. This condition will occur for all accesses along
the Frontage Road with or without the Vail Marriott Residence Inn project. Delays at
stop control side street accesses with arterials is normal and expected in peak hours.
However, even under these conditions, the ninety‐five percentile queues at the access
are anticipated to remain less than three vehicles in length.
M1234 Vail Marriott Residence Inn Redevelopment August 5, 2016 Page
22
5.3 Entering Sight Distance
As the redeveloped site is expected to be a commercial facility with minimal multi‐
unit truck trips, Per Table 4‐3 of the Access Code, the appropriate design vehicle for
entering sight distance is a single‐unit truck. Per Table 4‐2 of the Access Code, the
entering sight distance at the western access should be greater than 455 feet. From
the existing western access there appears to be in excess of 500 feet to the west of
the access and in excess of 700 feet east of the access. Entering sight distance exceeds
Access Code requirements.

5.4 Access Permitting
Given that estimated traffic volumes at the site are expected to increase in excess of
twenty percent over the existing volumes and the existing accesses will be
reconstructed, revised State Highway Access Permits will be required for the two site
accesses.
5.5 Multimodal Pedestrian and Bicycle Facilities
The applicant shall incorporate multimodal facilities in the site design as the project
progresses in the Town’s review and entitlement process. These plans shall be
coordinated for connectivity with the North Frontage Road bicycle and pedestrian
route, as well as the transit system.

6.0 Recommendations and Conclusions
The Marriott Residence Inn redevelopment anticipates replacing the existing Roost
Lodge, adjacent to the Interstate 70 North Frontage Road in Vail, with a 170‐room
hotel; 113 long‐term, local employee, rental apartments; and 100 leased parking
spaces.
As part of this effort, it is expected that the two existing site accesses will be
reconstructed and reconfigured.
The Transportation Master Plan and Access Management Plan Map provide guidance
for the access points to the subject property. These documents specify that the
easternmost access will be ingress only and the westernmost access will be egress
only.
As designed, the site is anticipated to operate most effectively with the easternmost
access as ingress only and the westernmost access as a full movement. Because the
site will include hotel as well as long‐term rental housing it is believed that site access
would operate most efficiently with this configuration. The easternmost access would
be used for hotel check‐in, shuttles, and deliveries. The westernmost access would
be the primary access for the apartments, parking garage, and hotel guests after
check‐in. The Town of Vail has indicated that they would support this change from
the Access Management Plan if the access points operate adequately as proposed. It
is understood that CDOT would need to also support this change and that the Access
Management Plan would need to be updated to reflect the change.
The proposed access spacing between the western site access and the adjacent
property access is approximately 120‐feet. The Access Management Plan Map
anticipates that the adjacent access will be closed and the property will gain access
from Meadow Ridge Road at the time of redevelopment. Per the Access Code, A
minimum distance of 250 feet between access points is required by the Access Code
along the Frontage Road.
The anticipated volumes turning left into the site are projected to exceed the
requirements set forth by the Access Code for the construction of an eastbound left
turn deceleration lane at the eastern site access. This lane should have 46 feet of
storage space and a 120 foot, 10:1 transition taper.
The expected increase in vehicular demand upon the two site accesses as well as the
proposed change in access design will necessitate the need for revised State Highway
Access Permits at both site accesses.
Pedestrian/bicycle connectivity via the North Recreation Path, as well as transit
access, should be maintained or enhanced in conformance with Town of Vail criteria.

Tom,
I am working on updating the traffic study for the Vail Marriott project and had a few questions for you:
1. The previous study assumed that the directional distribution with the Simba Run underpass would be 50% west /
50% east. Does this distribution still seem reasonable or should it be adjusted? This seems to be a reasonable
distribution
2. A 10% multimodal reduction was applied previously. The project as now proposed would include a significant
amount of longterm rental housing that will be deed restricted to local employees. Do you think 10% still applies
or could the reduction be increased slightly to account for the employee housing? We would recommend
maintaining the 10% reduction. We have only used a larger reduction in the Vail and Lionshead Village areas that
are on the High Frequency In Town Route.
3. A 0.5% growth rate was used to project the 2025 Master Plan traffic volumes to 2035 volumes. Should the 0.5%

be used to project 2025 Master Plan volumes to 2040? Yes, though we are in the process of updating our VTMP.
The numbers we will be using come from the I70 Underpass Traffic Study. See attached.
4. Do you have updated traffic counts for this location? We previously used 2013 counts provided. The 2012/13
counts are the latest we have.
