6. Administrative design adjustments approved by the Responsible Official pursuant to Section 3.6.1.1 may be appropriate when an existing building would impede roadway expansion; when transitioning from a different street section; or where strict compliance with this Development Code would pose a safety hazard. 1. When a preliminary plat, final plat or site permit proposes the construction of a new street, the requirements of this Article apply. 2. Sidewalks, streets and street trees must be installed and constructed in accordance with this Article. 3. Existing streets may remain serving existing development in their current configuration; however, they shall not be extended or substantially rebuilt except in conformance with this Article (see also Section 3.8.1.5 Existing Streets) Section 3.7.1.2Street Right-of-Way Width A. Street right-of-way width for Thoroughfare Plan streets must be dedicated as specified in the Transportation Master Plan. Alignments may be adjusted as approved by the Responsible Official. B.

A median may be added to the street cross-sections by increasing the right-of-way width. A median should be 18 feet in width in order to provide for landscaping and turn lanes. In no case will a median less than 8 feet in width be considered. D. The Responsible Official may require turn lanes, and additional right-of-way beyond that shown in the applicable street typical cross-section to accommodate these lanes when warranted. Section 3.7.1.3Measurement of Streets and Streetscapes A. Face of Curb. All measurements of parking spaces and lane widths are taken from the face of curb and are inclusive of the gutter. B.

Whenever funding is available and site conditions allow, rights-of-way may be designed to infiltrate stormwater, either through porous pavement treatments, curb cuts, or by directing stormwater into bioretention cells. Plants used in a bioretention cell must be comprised of species that require low maintenance and can tolerate frequent inundation as well as periods of drought. C. Street Lighting.
