Green Streets Lead Consultant
Community Design + Architecture (CD+A) is involved with two different Environmental Protection Agency (EPA) funded programs to assist cities in the United States move toward implementation of Green Streets strategies. Green Streets refers to the use of landscaping, pervious surfaces, and other improvements to capture, treat, and convey stormwater from public rights-of-way. The benefits of a Green Streets approach include reduced water pollution and reduced demand on water treatment facilities, as well as introducing increased landscaping and creating more walkable communities. Additionally, Green Streets approaches create opportunities for other urban design and traffic calming elements that establish a more attractive, safe, and enjoyable public realm; among these are vegetated curb bulb-outs and edge islands, and larger features like roundabouts and pedestrian plazas featuring rain gardens.
For EPA's Sustainable Communities Building Blocks Technical Assistance program, CD+A, as part of a multi-disciplinary team, is leading the of EPA's existing Green Streets Strategy tool. CD+A's work is being utilized through a series of customized workshops with five cities: Dayton, Ohio; Bellevue, Nebraska; Fort Lauderdale, Florida; Maui, Hawaii; and Lynchburg, Virginia. The goal of the work is to achieve nationally applicable guidance for a variety of physical and regulatory contexts. CD+A is developing implementation-focused tools to facilitate inter-departmental cooperation and coordination; defining the comprehensive range of community benefits; stressing the importance of policy maker education and commitment; and furnishing an overview of life-cycle maintenance costs and savings.
For EPA's Greening America's Capitals program, CD+A is leading a team to identify opportunities and develop customized Green and Complete Streets designs for Last Chance Gulch Avenue in Helena, Montana, which travels through the center of town along an existing and expanding commercial main street district. CD+A is proposing Green and Complete Streets strategies to implement green infrastructure and pedestrian, bicycle, and vehicular facility improvements. CD+A developed several alternative concepts and held a three-day charrette to present ideas, solicit feedback, refine concepts, and review designs with city staff and stakeholders.
