RE: Human Bean
Questions posed by Planning and Zoning board members are shown m bold. City traffic staff responses
are in italics, and additional information is shown below that.
1. Why doesn't the T.I.S. address stacking at the College access? Does City staff
anticipate any issues with stacking at the proposed access?
At the time of the scoping for the TIS, it was not believed that stacking on South
College would be a problem when considering the "double drive thru" and the set back
from the roadway. The initial trip generation estimate actually put the level of TIS at
Memorandum " but we decided to also look at the background traffic for the short term
horizon. If a stacking analysis is requested by the P&Z Board; then it would be prudent
to pull the item from the agenda and allow the applicants traffic engineer to prepare the
analysis for next month's meeting".
It is important that the vehicles entering in the development (especially in the am peak
hour) waiting for service do not stack into the roadway. The current design shows that
there is stacking room on the property for at least 10 vehicles. Assuming 31 entering
cars in the peak hour, and a very conservative 5 minute wait, that would be a total of
155 vehicle waiting minutes, or an average of less than two cars present at the ordering
windows during the am peak. It is recognized the am traffic.does notarrive entirely consistently,
but with a safety margin of 5 fold, this appears adequate. The,
North College Human Bean did on occasion stack onto the roadway during the am peak,
prior to the reconstruction that allowed the double drive thru lane. Since the reconstruction
which, like the proposed South College Human Bean, has significantly more
storage available, the stacking doesn't appear to be an issue on College Avenue. 2.
The trip generation data provided in the T.I.S. includes weekends (avg taken for
31 days) which, in the opinion of one PU Board member, would be relatively low
volume days compared to weekdays. Therefore, true representative trip 5
