I finally got my TIS comments into Accela. I think I have the plans at home and will give them a review for landscaping
issues so I may still have comments but they will be finalized either Friday or Monday (at all day training in Denver
Friday). The following are my TIS comments:
02/08/2012: The TIS analyzed the College and Conifer intersection with a north bound right turn lane. Unfortunately one
does not currently exist at that location. It is being built with the current improvements so analyzing it in the short and
long term is appropriate. Please revise the TIS appropriately. (ACTIVE)
03/08/2012: The City believes more than 10% of the trips generated by this project will pass thru the Linden and
existing Vine intersection. Traffic Op's recreated the Linden/Vine and the College/Vine intersections and increased
volumes significantly. The intersections didn't fail nor did individual movements fail or even suffer significantly. It is
concluded that the two intersections can accommodate more traffic than analyzed without significant negative impacts.
As such no revision to the TIS for that issue will be requested. (RESOLVED)
