RE: RESPONSE TO PLANNING DEPARTMENT COMMENTS / Proposed RED
ROBIN RESTAURANT / Fort Collins, Colorado
Dear Craig:
I have reviewed the comments provided by the Fort Collins Planning Department on the Traffic
Impact Analysis and have the following responses to submit.
1) More information was requested concerning the recommended design geometries on
the northbound approach of the Boardwalk/Harmony intersection.
Attached is a sketch of the recommended geometries for review. The sketch shows a dual left
turn on the northbound approach of the intersection at Boardwalk/Harmony. The inside lanes are
11 feet wide and the curb lanes are 12 feet wide. A two foot painted median separates the
northbound and southbound traffic. The dual left turn can be installed without reconstruction of
the intersection.
A dual left turn on the northbound approach is recommended because of the heavy left turn
demand, especially during the Saturday noon peak. Also, a dual left turn would provide more
storage which would help clear the entrance to the shopping center. Right now' on Saturdays the
entrance intersection congests due to the northbound left turn storage that backs up into the
intersection.
A single left turn could be implemented if the intersection (specifically the southbound approach)
cannot accommodate the dual turn from the northbound approach. A drawback to the single left
turn is that it would require a reduction of green time on Harmony. A study of signal progression
on Harmony would be required to determine if the green time on Harmony could be reduced for
the Saturday noon period. In comparison, a dual left turn would not require a reduction of green
time on Harmony.

2) Clarification was requested on the trip generation data.
The following chart should help clarify the trip generation data. The I TE Trip Generation Manual
(Fifth Edition) was referenced for this information along with actual experience at other RED
ROBIN Restaurants across the country.

3) The Planning Department will not allow a new curb cut from Boardwalk as
recommended by the Traffic Impact Analysis.
A new curb cut at the suggested location would significantly improve circulation through the
center and avoid congestion on Boardwalk at the present entrance. The Traffic Impact Analysis
reports that a homemade stop sign has been placed at the first internal intersection from the
entrance to help alleviate the confusion that obviously exists. The narrowness of the intersecting
roadways and the heavy volume of traffic combine. to create an awkward situation.
As reported earlier, the northbound left turn storage from the Boardwalk/Harmony intersection
backs up into the entrance intersection causing congestion. The recommended dual left turn in
item one will eliminate the back up and reduce congestion significantly for the time being.
Presently, the southbound left turn into the center is not a problem as it is virtually unopposed
by northbound traffic.

However, development is planned for the adjacent area including a residential community of 600
homes. Development as planned will increase traffic: on Nvirdwalk, eslxtc <<lly in the northbound
direction. Should this happen, the southbound left turn into the center from Boardwalk would be
significantly delayed and likely back up into the Boardwalk/Harmony intersection. The
recommended location would add more than 200 feet of leli turn storage liar the southbound left
turn movement which would keep the left turn from causing; problems.
Therefore, moving the primary entrance for SAMS and RIJILDERS SQ11ARE to the south as
recommended in the Traffic Impact Analysis serves two distinct purlwses. One, it rclicves an
internal circulation problem and, two, it solves a potentially significant congestion problem at the
present entrance should development occur as pl.-coned.
The recommendation is made strictly to resolve real and potential traffic operational problems.
