(B)
A figure showing the roadway lane configurations for existing and proposed
improvements, including accompanying identification of the parties responsible for
the improvements.

Recommendations
(A)
The recommendations portion of the analysis shall include the following:
(i)
For signalized intersections, a list of specific recommended improvements to
achieve the minimum LOS D for each movement and approach. If the existing
LOS falls below this threshold, the recommended improvements shall at a
minimum maintain the existing LOS and delay;
(ii)
For unsignalized intersections, a list of specific recommended improvements to
achieve the minimum LOS D for each movement. If the existing LOS falls below
this threshold, the recommended improvements shall at a minimum maintain the
existing LOS and delay;
(iii)
For both signalized and unsignalized intersections, if a single vehicle would
cause a reduction in the LOS and/or delay, then the applicant may request
that this impact not be counted in the TIA; and
(iv)
Any improvements identified in the No Build analysis that are not a funded
Town, State, or federal capital improvement project.
(B)
All recommendations shall be:
(i)
Consistent with adopted plans; and
(ii)
Supported by the data provided in the analysis.
k.
Appendices
A separate appendix for each of the following shall be included in this section.
(1)
Traffic count data;
(2)
Trip generation calculations;
(3)
Intersection capacity analysis, including the associated Synchro output;
(4)
Any other additional documents or analyses required per the MOU;
(5)
A bicycle and pedestrian network plan, if the proposed development application is for
Type 1 Subdivision Preliminary Plat Approval (Section
2.5.6.B.1), Type 2 Subdivision
Preliminary Plan Approval (Section
2.5.6.B.2), or Major Site Plan Approval (Section
2.5.7.B);
(6)
Signal plans, including timing plans;
(7)
A figure showing the approved development trips; and
(8)
Any future volume calculations.
Incorporation of Recommended Improvements into Proposed Development or
Decision
The applicant is expected to incorporate improvements recommended by the transportation impact
analysis into the proposed development to the extent they are required by Section
5.8.5, Developer Responsibility for Access and Circulation Improvements.The entity deciding the
application shall consider the transportation impact analysis as part of the review of the
application, and may incorporate such recommended improvements in its decision—e.g., as
conditions of approval requiring provision of the recommended improvements or requiring
modification of the development’s uses or intensity, or as a basis for denial of the application.
