DRAFT Comprehensive Transportation Plan Update: 2/23/2018 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.
