 EPA's Brownfields Sustainability Pilots provide technical assistance to assist
 communities in achieving greener, more sustainable results when redeveloping
 brownfields. These pilots also provide models for other communities across
 the country.
 EPA provided the City of Greenville, South Carolina with technical assistance
 for the sustainable redevelopment of a one acre property with a former service
 station and adjacent supermarket. EPA helped analyze the redevelopment plans
 to incorporate green and sustainable features into a conceptual site plan. More
 specifically, the technical assistance looked closely at stormwater management
 strategies for the site that will promote sustainable redevelopment opportunities
 elsewhere in the community.
Green Avenue Sites Background
The former service station (0.46 acres) and supermarket (0.54 acres) make up the designated land for the
redevelopment project. Both businesses began operating in the 1960s and operated until 2002. In November 2002,
the City of Greenville conducted a Phase I assessment; subsequent soil and ground water sampling occurred
in December 2006 and February 2007. The results of these assessments revealed that the properties were
contaminated with benzene, toluene, ethylbenzene, and xylenes, methyl-tert-butyl ether, ethylene dibromide, and
naphthalene. In 2002, nine underground storage tanks and one above ground storage tank were removed from the
site, and in 2009 the structures on the site were demolished.
The city plans to redevelop the site into workforce housing and supplement the city's stormwater infrastructure by
creating a dedicated dry pond to channel and contain excess runoff.

Project Highlights
EPA's technical assistance to the City of Greenville included the development of conceptual design considerations,
including stormwater management principles, for the development of the site. Essential components of the design
considerations included infrastructure improvements, development goals and zoning requirements, and ground water
monitoring requirements. The design considerations for the site include:
                                                    • Infiltration trenches
                                                    • Filter strips
                                                    • Pervious paving
                                                    • Rain barrels
                                                    • Solar panels
As a result of the design considerations, a site redevelopment plan was developed for the property. The plan
includes single family homes overlooking greenspace. This design provides sustainable features for the site and an
environmentally friendly property for living.
The city expects to implement the redevelopment plan once it identifies a developer to undertake the small scale
residential development plan.

          Challenges and Lessons Learned
          Ensuring the Preservation of
          Monitoring Wells
          The city uses 18 wells in the 0.64 acre
          property for the monitored natural
          attenuation of ground water. Since the
          housing development must not disturb
          these wells, the consultant developed a
          site plan that would account for continued
          access.
          Working with Local Ordinances and
          Stormwater Authorities                             Mjsfs rendering of f/ie MUre Green Avenue site.
          Local ordinances and inexperienced stormwater management authorities can present obstacles when
          designing for and installing sustainable stormwater management features such as bioswales and rain gardens.
          Communities undertaking sustainable redevelopment activities should be prepared to deal with regulatory and
          information hurdles.
