The G3 Academy highlights the efforts of our Mid-Atlantic towns and cities utilizing Green Streets to integrate green stormwater management practices with other G3 Practices to create sustainable and resilient communities. The G3 Academy & partners support the education, design and implementation of green streets in mid-Atlantic communities through a variety of successful activities, including grants, training forums, charrettes, and the development of resource materials.

G3 Charrette

A Charrette is a collaborative meeting in which stakeholders from a variety of backgrounds gather together to develop a shared vision for the future.  This may mean discussing solutions to problems or issues, or thinking about the possibilities of the future.   Charrettes for Green Streets usually involve local residents, community leaders, business owners, representatives from city or municipal government, municipal divisions (such as streets, water, parks), and professions in landscape Architecture, Engineering.  Charrettes generally take place over a short time period – generally a few hours to 1 or 2 days - and involves a mix of facilitated discussion combined with periods for open discussion and visioning.  The combination of the rapid pace and the need to come to consensus helps the group to effectively sort out issues of importance and develop creative solutions.  The outcome of a charrette can be a set of concept drawings, or a guidebook, or even just a better understanding of the concerns around an issue.

One product of the G3 Academy, the Town of Bladensburg, Maryland, Green Streets and Green Jobs Charrette and Design Guidebook, was recognized by the US EPA as a National Best Practice for Water (2010).  As part of the G3 initiative, a “pilot charrette” brought together stakeholders and experts in a diverse set of fields to collaborate on design and implementation recommendations for the greening and revitalization of the Town of Bladensburg, MD.  The goal was to improve protection for the Anacostia River watershed and usher in a “sustainable Bladensburg.”

G3 partners designed the charrette to address multiple community issues and interests, including watershed-driven community planning; greener stormwater management; renewable energy use and greenhouse gas reduction; green business; alternative financing strategies; and job creation. The Town of Bladensburg was also interested in the use of recycled materials in green construction and creating pedestrian-friendly, traffic-calming streets. The charrette produced a feasible set of recommendations for consideration in the development and implementation of the final green street design plan. The charrette process, and resultant guidebook with recommendations, was named one of the top 7 Best Management Practices in 2010 by EPA’s Office of Water.

G3 Forum & Design Competitions

The G3 Initiative was designed to build understanding and a peer-to-peer network around the concept of Green Streets.  The G3 Forum has proven to be an effective tool for building this network and providing communities with training and opportunity for discussion.  They are able to share their experiences and lessons learned.

The first interactive Green Streets, Green Jobs, Green Towns (G3) Forum and Training Workshop was held in April 2011 and had more than 200 participants, including local and state officials, directors of transportation and public works, community college and workforce trainers, non-government organizations, state and local planners, and business and industry representatives.  The two-day event brought together leaders in low impact development (LID), green infrastructure, green jobs, and renewable energy, among others.  A compendium of the sessions is now available for greater transfer by the G3 Academy.

G3 also encourages the use of Green Infrastructure Design competitions to introduce local designers, engineers, architects, and landscape architects to the integration of sustainable design practices for stormwater management through Green Infrastructure. These Design competitions have been successful in teaching professionals that GI and other sustainable practices can be incorporate in the development of a project with greater costs savings and increased aesthetic value. The City of Philadelphia’s “Soak it UP” competition and Houston’s Low Impact Design Competition are featured.

G3 Grants

To highlight its innovative approach, in late summer 2010, Administrator Lisa P. Jackson announced the G3 Initiative and its groundbreaking green streets collaborative assistance grant opportunity as a key component of the EPA’s strategy for restoring the Chesapeake Bay.  To support this initiative, the EPA, through its G3 partners, made more than $250,000 (matched, in-kind, by the State) available for local governments and non-governmental organizations in the Anacostia River watershed to promote and develop green infrastructure for stormwater, renewable energy use and green jobs. The funds were distributed through a watershed assistance partnership with the Chesapeake Bay Trust, the Maryland Department of Environment, and the Maryland Department of Natural Resources.

Since 2010, the G3 Partnership has awarded 60 grants to Mid-Atlantic communities.  These grants have infused over $4.9 million into green initiatives and resulted in over $9 million in G3 Projects.

The G3 Partnership has made grants to every Mid-Atlantic state  (Pennsylvania, Delaware, Maryland, Virginia, West Virginia, Washington DC.) These grantees have in-turn become G3 partners and champions, helping to demonstrate and transfer green street practices to other interested communities and stakeholders. A number of communities have also reported an increased ability to attract additional funding support as a result of the grants and the support of the G3 initiative.

The G3 Partnership continues to grow with partners adding grant funds and capacity.  In 2014, recognizing the success of the program to implement real green solutions, the State of Maryland provided nearly $3 million in support of the G3 Grants program. 

G3 grants are managed by the Chesapeake Bay Trust and are generally announced in December with proposals due to the Chesapeake Bay Trust in February.  Grants are awarded in late spring or early summer.  For the latest G3 Grants RFP please visit the CBT website at: http://www.cbtrust.org/site/c.miJPKXPCJnH/b.7735695/k.5E92/Green_Streets_Green_Jobs_Green_Towns.htm
