Street Design Manual

Section 3.2.1 Sensitive Area Streets In areas of Raleigh where stormwater does not drain into pipe systems, other forms of drainage must be provided. Along encompassed streets, open channel drainage ditches are typical and must be accommodated within special cross-sections. The following roadway cross-sections are intended for use in these “Sensitive” areas. A. Sensitive Area Parkways are semi-limited access corridors, and are often used to preserve scenic views. They are intended primarily to support regional travel. Medians are a standard feature of parkways in almost every case, except where a narrower cross-section is needed to minimize right-of-way and environmental impact. B. Sensitive Area Avenues are for use in low-intensity areas that do not have sewer provisions. They have relatively narrow paved widths, which includes shoulders for bicycle and pedestrian uses in retrofit situations lacking sidewalks. C. Sensitive Area Residential Streets are appropriate in rural conditions with large lot homes, without water and sewer provisions.
