Vail Valley Medical Center Master Plan – Traffic Impact Study
After
review of the Traffic Volume Development report for the Vail Valley Medical Center Master Plan dated September 30, 2014; we offer the following notes and comments for confirmation/clarification
and discussion;
The trip generation is based on # of parking spaces and existing count data; not based on ITE use categories. How does this generation number compare with ITE trip
generation?
It should be noted that the ~50+% discrepancy in volumes between VVMC counted traffic and the VTMP counted volumes for existing traffic can easily be explained since the
VVMC traffic counts were done midweek and the Frontage Road sees significantly more volume on the weekends with skier traffic.
With a right turn in volume of 239, the right turn required
decel lane may be +/- 240’; how will this be accommodated in the Roundabout or in the “First In and Alone” scenarios.
The First In and Alone scenario seems potentially problematic;
the
left-in only for emergency vehicles will be difficult to control,
the U-turn movement for 200+ vehicles at peak hour will be difficult to enforce/manage,
the U-turn will be difficult
to design and sign within the ROW, where is this U-turn proposed to be located?
Both the Roundabout and First In and Alone scenarios need to be vetted more in design to understand if
they are feasible and approvable. It will also be important to get CDOT’s input on whether these solutions will be approvable in CDOTs ROW. If it is determined neither are feasible
or approvable what it the next option?
On-site circulation will be critical for this amount of traffic entering off the Frontage Road. This should be vetted in more detail.
Vail Valley Medical Center Master Plan – Loading & Delivery Study
The loading and delivery table provided shows that a WB-40 size vehicle comes at least once a day Tuesday thru Friday.
It also indicates that the Pepsi/Coke trucks are WB-40, the ones we see in Vail are generally classified as WB-50. This should be taken into consideration when designing a loading
& delivery facility.
The table also indicates that the non-regular deliveries or as needed deliveries occur 3x in a given day. This seems very regular, and should be included as such.
Based
on the number of deliveries that come to the VVMC, the loading and delivery facility should be able to handle at least the peak number of SU trucks in one hour (6), plus be able to accommodate
at least one WB-50. This would accommodate the existing uses. Further discussions should be had as to what may happen in the future. Additional capacity should be considered. The
proposal to use the west parking lot for daily WB-40 deliveries is not recommended as this will block necessary parking spaces that need to operate and turn over during the day.
The
design of the facility should accommodate a 2’ buffer on each side of the trucks for all turning movements, and take into account the blind turn of large articulating vehicles.
It should
be also shown how other in-frequent oversize vehicles will be accommodated on site in the West Lot (i.e. WB-67), since no deliveries will be aloud on West Meadow Drive or within the
Right of Way.
