Upper Rock District

Rockville, Maryland

The proposed Upper Rock District, a 20-acre mixed-use development at the intersection of I-270 and Choke Cherry Road, is Montgomery County’s first post-suburban community.

Upper Rock District’s developer, The JBG Companies, retained Wells + Associates to provide transportation planning and traffic engineering services and to participate in the week-long public design charette that involved local residents, public officials, public agency staff, project planners/ engineers/environmentalists, the developer, homebuilders, utility companies, and others.

With an emphasis on green development, Duany Plater-Zyberk & Company, the project’s designers, have introduced cutting edge innovations to transform an underused auto-oriented office park into a mixed-use residential community, including:

•	Loft conversion of an obsolete suburban office building,
•	Live-work units
•	Single story incubator retail, providing affordable retail space for small businesses, such as craft sales and restaurant start-ups.

Wells + Associates also prepared the first traffic study under the City of Rockville’s new Comprehensive Transportation Review (CTR) guidelines. The CTR included:

•	Site Access and Circulation Analysis – auto and non-auto
•	Automobile Traffic Analysis – 11 intersections
•	Non-Auto Off-Site Analysis – evaluation of pedestrian, bicycle, and transit modes and intersection safety.

Due to mixed-uses, Wells + Associates determined that the peak hour trip generation for the proposed project is a fraction of the peak hour traffic generated by comparable office development. Wells + Associates also identified road improvements that would mitigate site traffic impacts.
