Morrisville Unified Development Ordinance - April 2019

Article 5: Development Standards Section 5.8. Access and Circulation 5.8.6. Vehicular Access and Circulation

transportation impact analysis shows that the development itself is expected to generate sufficient traffic to warrant design of the street as a major or minor thoroughfare (see Section 5.8.6.B, Transportation Impact Analysis), the developer shall be responsible for constructing the street (including any bikeway, sidewalk, and other associated access and circulation improvements) in accordance with this section’s standards for a major or minor thoroughfare, as appropriate; otherwise, the developer shall be responsible for constructing the street (including any bikeway, sidewalk, and other associated access and circulation improvements) to meet at least those standards required by this section for a collector street. B. Off-Site If a development site fronts on and obtains vehicular access from an existing street, the developer shall be required to dedicate additional right-of-way along the street frontage or in the vicinity of the development and to provide roadway, bikeway, sidewalk, and other access and circulation improvements within the street right-of-way that are reasonably necessary to ensure the safe, convenient, efficient, and orderly accommodation of vehicular and pedestrian traffic demands and impacts generated by the proposed development. Such improvements may include, but are not limited to, turn lanes, deceleration and acceleration lanes, widening or paving of substandard roadways, medians, bikeways, sidewalks, sidewalk ramps and crossings, street lights, bus shelters, relocation of existing driveways, and the relocation or improvement of utility lines and facilities needed to accommodate street improvements. The extent of required dedications and improvements related to the abutting street shall be roughly proportional to the traffic demands and impacts generated to and along that street by the proposed development. A. Circulation Plan Applications for Type 1 Subdivision Preliminary Plat Approval (Section 2.5.6.B.1), Type 2 Subdivision Preliminary Plat Approval (Section 2.5.6.B), Major Site Plan Approval (Section 2.5.6.B.2), or Minor Site Plan Approval (Section 2.5.7.C) shall include a circulation plan that addresses street connectivity, emergency and service vehicle access, parking movements, accommodation of loading operations, turning radii, traffic calming measures where future “cut- through” traffic is likely, and similar issues. The Planning Director may waive the requirement for a circulation plan on determining that a proposed development is expected to have no impact on circulation or proposes no change in existing circulation patterns. This provision shall not be construed to exempt development that includes additional parking, driveways, or substantial modifications to the existing pedestrian network. 5.8.6. Vehicular Access and Circulation 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; 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.
