Invited Session: Closing Dumpsites

Transforming a Large Inactive Urban Landfill into a Successful Park

Tuesday, September 26, 2017
8:45 – 9:15
Convention Center

A large city owned, inactive landfill located on a 100-acre parcel of land in a heavily populated area adjacent to a scenic river faced a multi-million-dollar closure. The city sought to develop a post closure plan that would turn a significant piece of underutilized real estate into a community asset. A citizen’s advisory committee was appointed to work with city departments and a consultant to develop a plan to revitalize the 85-acre landfill for public access and use. Capping and closure of the landfill required a plan to contain the waste mass while controlling the production of landfill gas (LFG). These requirements were in close connection with the public safety demands of what was to become a heavily used, significant urban park. Working the grades and proposed use of the landfill for playing fields and other active recreational uses posed a significant challenge in developing the final grading of the site as well as providing for the design of a “hidden” LFG collection and control system. This presentation will discuss the history of the site, from initial use as a drinking water treatment plant, through the years as a municipal solid waste landfill, to its final closure and development of a large urban park. Design features will be shown for the closure, capping, park development and LFG system.

Following the presentation, participants will be able to monitor and document the activities involved in closing and capping a landfill properly, maintain proper records and archive for future activities and/or reuse of the site.
