DRAFT Comprehensive Transportation Plan Update: July 23, 2018 version

STANDARDIZED CROSS-SECTIONS

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 B-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 of 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 Town of Morrisville’s street hierarchy described in Chapter 3 and Figure 3-2 . While there are always exceptions, establishing these standardized cross-sections and their appropriate context will be beneficial as future improvements and growth are 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 . Dimensions provided with the cross-sections are based upon the standard cross-sectional element dimensions in the NCDOT “Typical” Highway Cross Sections Memo (dated May 5, 2014). The Town of Morrisville reserves the right to modify the cross-sections as needed, including but not limited to requiring larger rights-of-way, more substantial bicycle and pedestrian accommodations, or reallocating use of the paved travel way. 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 street network. The Town’s standard cross-sections include curb and gutter. 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 on pages B-2 to B-7 are preferred by the Town. Narrower dimensions may be considered based on coordination with Town staff, and are subject to approval by NCDOT along state-maintained roadways. Similarly, the typical right-of-way dimensions may be influenced by the surrounding land use or function of the road. Table B-2 provides an inventory of Morrisville roadways, their street hierarchy, and the most applicable standard cross-section. Table B-2 on the following page is intended to be a useful tool for developers choosing to locate in the Town of Morrisville. The inventory of roadways and their corresponding cross-section will provide certainty for developers as to the required roadway improvements and needed rights-of-way for the improvements. It is anticipated that developers will begin with the standard cross-sectional minimums, and that the Town of Morrisville may require alternative elements to ensure that the roadways best serve both residents and development. The Town of Morrisville’s standard dimensions for outside curb-and-gutter is 2.5 feet and for median curb is 1.5 feet.
