EVERETT STREET GREENING DEMONSTRATION PROJECT

Phase 1: Planning and Design (February 2008 - January 2009)
Phase 2: Implementation (December 2009 - June 2010)
Phase 3: Brentwood Street Greening

Project Background

In February of 2008, CRWA was awarded an Urban Forestry Challenge Grant by Massachusetts Department of Conservation and Recreation (DCR). This grant enabled CRWA to develop a Green Street demonstration project along a section of Everett Street in North Allston. The project involved the design and construction of a system of green infrastructure that maximizes the use of street tree cover for stormwater interception as well as temperature and air quality improvement and as a result illustrates the connection between green infrastructure, stormwater management and ultimately water quality.

The project creates a lush, green streetscape by retrofitting a part of the St. Anthony’s Church site, along the building occupied by the German International School of Boston. The project benefits the entire community on North Allston/ Brighton, and is the first part of an effort to convert all of Everett Street to a green street. The implementation of rain gardens, permeable pavement and stormwater tree pits improves the site aesthetically and at the same time collects and treats stormwater runoff. Approximately 2,500 square feet of asphalt next to the school building has been replaced by an attractive green landscape that includes 7 new trees, a rain garden and a stormwater tree trench. The new vegetation helps beautify the area, while providing shade and reducing summer temperatures, improving air quality, and aiding the management of storm water runoff.

Phase 3: Brentwood Street Greening

As part of the continued greening of Everett Street, CRWA organized the planting of five trees with funding from Grow Boston Greener Initiative.  On November 19, 2011 volunteers from the German International School of Boston, Saint Anthony’s Church, and the Allston/Brighton community turned out to dig holes, prepare the soil, and plant a combination of Red Maples and Serviceberry trees. 

GISB staff and parents, school children, Church members and residents from adjoining area enjoyed the opportunity to help green their community.  The trees will help to decrease storm water runoff and provide benefits including shade and greenery along Brentwood Street. 

Phase 2 - Project Construction

Construction of the Everett Street Greening Demonstration Project at the German School site.

In June 2009 CRWA was awarded a $20,000 grant from the Harvard Partnership Fund as a match for funding from DCR to help implement the Everett Street Greening Demonstration Project.

Project construction started on April 12, 2010, and continued for two weeks. Following a site design created by CRWA, independent landscape contractors removed existing asphalt pavement and installed various low impact development (LID) stormwater management techniques, including a rain garden, native plant beds, a new grass lawn and a walkway made of permeable pavers.

Seven new street trees were planted along Everett Street, including one red maple that is part of a stormwater tree pit, a LID technique that infiltrates, treats and absorbs stormwater runoff on site.

On May 15, 2010, community members and local volunteers participated in a day of collaborative greening. Native trees and shrubs were planted throughout the site and mulch was spread on the plant beds. Participants received training on the seasonal and annual maintenance that is required for the sustainable landscape features. During the following weeks, wooden benches and planters were installed, creating an inviting seating area underneath the maple trees.

On June 21, 2010, Mayor Menino inaugurated the Everett Street Community Green Space. The public gathering highlighted the significant site improvements and continuing commitments to neighborhood and city-wide sustainability goals.

Phase 1 - Planning and Design

DCR's Urban Forestry Challenge Grant enabled CRWA to start Phase 1 of developing a Green Street demonstration project along a section of Everett Street in Allston and Brighton.

Phase 1 of the project included a number of tasks:

Task 1: Site selection and assessment of existing conditions

Following a site visit with representatives from DCR, City of Boston Parks Department, Urban Ecology Institute and ABGSA, the project team short listed three sites out of the 6 being considered at the start of the project. These three sites (namely 119 Braintree Street site, St. Anthony's / German School site and Brian J. Honan Apartment site) were further evaluated based on criteria such as runoff volume, pollution level, implementation, permitting, visibility, maintenance, potential for public education and involvement. On the basis of the ranking, the St. Anthony's / German School site was selected for further site assessment, documentation of existing conditions, and concept design.

Task 2: Evaluation of green street design elements and best management practices

CRWA's Green Roof BMP Info Sheet

Part 1 - The project team completed the evaluation of various green streets elements like stormwater planters, tree pits, rain gardens, permeable pavers and pavements in terms of their effectiveness in capturing and treating stormwater and compiled fact sheets summarizing this information (see example at right).

Part 2 - In addition to the above, CRWA drafted a document that summarizes the research that the project team had undertaken on ev
