Draft Comprehensive Transportation Plan Update_September 25, 2017

APPENDIX

DRAFT

STANDARDIZED CROSS-SECTIONS As recommendations are identified for the roadway network, it is important to consider their future design and function. The Town of Morrisville Comprehensive Plan Update attempts to do this by developing a series of standardized cross-sections based on those being used by the Capital Area Metropolitan Planning Organization (CAMPO) and the North Carolina Department of Transportation (NCDOT). Table A- 1 presents a context-based guide for the application of these standardized cross-sections in the Town of Morrisville. This table offers a greater understanding how street design can complement the land use context of a given area, which in turn offers an expression of consistency with stated NCDOT policy for design elements as well as Complete Street objectives. The table is organized around the Community Types derived from the region’s Connect 2045 scenario plan (Rural, Suburban, City & Town, Industrial, and Special). Understanding that categories “Rural,” “Industrial,” and “Special” are limited locations that take on design characteristics of the other two categories, the table has been limited to Suburban and City & Town. While there are always exceptions, establishing these standardized cross-sections and their appropriate context will be beneficial as future improvements or growth is considered in the Town.

The pages that follow display the standardized cross-sections that have been developed for use within the Town of Morrisville Comprehensive Plan Update. Specific dimensions have not been provided within the cross-sections. Coordination with the Town will be needed to determine the preferred details for each corridor, and their application within the Town’s existing and proposed roadway network. The Town’s standard cross-sections include curb and gutter. However, the Town may choose to proceed with curb and gutter on one side of the road with shoulder on the other side, such as in instances where the roadway parallels the railroad. A range of different bicycle and pedestrian accommodations are displayed in the cross-sections. Coordination with Chapter 4 of this document as well as with Town staff will be needed to determine the most appropriate bicycle and pedestrian accommodations for a corridor. When a sidepath is included on one or both sides of the road, it will take the place of a sidewalk in that location. The lane widths provided below are preferred by the Town. Narrower dimensions may be considered based on coordination with Town staff and are subject to approval by NCDOT. Similarly, the typical right-of-way dimensions may be influenced by the ownership, context, or function of the road.
