movements, accommodation of loading operations, turning radii, traffic calming measures where future “cut - through” traffic is likely, and similar issues. 2. The Planning Director or Fire Marshall may waive the requirement for a circulation plan on determining that information displayed on a Circulation Plan can be clearly displayed on the Site Plan. This provision shall not be construed to exempt development that includes additional parking, driveways, or substantial modifications to the existing pedestrian network. Purpose The Transportation Impact Analysis (TIA) is a part of the overall development review process conducted by the Town of Morrisville to safeguard the safety, health, and well-being of its citizens. The TIA is intended to: a. Assess the impact of a proposed development on the roadway capacity, public transportation, bicycle, and pedestrian transportation systems; 1.

B. Transportation Impact Analysis

b. Help mitigate potential effects of a proposed development on the transportation system; and

c. Identify solutions to potential problems and recommend improvements to be incorporated as required conditions to a proposed development. 2. Thresholds for a Transportation Impact Analysis

a. General Thresholds

(1) A TIA is required if one or more of the following thresholds are met.

(A) The proposed development is expected to generate 100 or more vehicle trips over any one-hour period or 1,000 or more trips per day based on the most recent edition of the Institute of Transportation Engineers (ITE) Trip Generation Manual;

(i) The number of trips generated by a development shall be calculated based on the net new trips, with any trips generated by existing development on the proposed site subtracted from the new trips expected to be generated. (ii) Internal capture and pass-by trips (if applicable) shall be shown in the TIA.

(B) A proposed amendment to the Comprehensive Plan that would redesignate the development site to a more intensive trip generation land use classification (e.g., Low Density Residential to Medium Density Residential); (C) A rezoning application proposes reclassification of the development site to a more intensive trip generation zoning district (e.g., Low Density Residential District to Medium Density Residential District) that is not consistent with the adopted Comprehensive Plan; (2) A TIA for an approved, built out, or partially built out development greater than two years old, as determined by comparing the submittal date on the approved TIA, would be required to be updated if one or more of the following thresholds are met. This requirement does not apply to any part of a development that has been vested.

The development is proposed to have
