Remediation Infrastructure: A Comprehensive Development Strategy for the Remediation of the Gowanus Canal Heather Fuhrman, Associate ASLA City College of New York, New York faculty advisors: Achva Benzinberg-Stein, FASLA; Denise Hoffman-Brandt and Hanque Macari
Project Statement
The usage of Gowanus Canal, located just off New York City's East River Estuary, has declined over time due to development of
alternate shipping methods. Today the Canal suffers from environmental contamination, economic obstacles, and social indecision.
This project looks to develop a remediation infrastructure using economic, environmental, and social determinants to generate a
variety of multi-scale apparatus as remediation tactics implementing a system of networks to generate a comprehensive
development strategy for the Canal.
Project Narrative
This graduate thesis project involves an approach which allows for the deployment of a range of multi-scale tactics that act as
networks to create an infrastructure for the remediation of the Gowanus Canal. This 1.5 mile canal is situated in the heart of the
once thriving industrial core in of Brooklyn. Adjacent to the Canal are several industrial based businesses as well as an assortment
of industrial relics and abandoned sites. The Gowanus is emblematic of the decline of industrial waterfront landscapes in this post-
industrial climate in relation to its environmental, economic, and social challenges. This area suffers from environmental pollution,
economic obstacles, and social indecision, which has physically scarred the environment and divided the community. Environmental
contamination, the result of the heavy commercial and industrial use of this once thriving industrial core, has created a condition
where chemicals and waste materials have leeched into the environment, causing a potentially harmful situation to the both the
surrounding residential and ecologic environments. Economic challenges associated with previously proposed redevelopment
campaigns have also plagued the site due to the overwhelming cost associated with brownfield clean up.
The topic of redevelopment also creates controversy among a variety of community based groups lacking a single overriding
political mechanism creating social indecision. As recent as May 2008, the New York City Department of City Planning proposed a
redevelopment strategy for this area. This draft re-zoning proposal included a strategy for mixed-use zoning, public waterfront
access, affordable housing, and clean-up as a condition for redevelopment. However, a variety of community based groups involved
in the process, including the Gowanus Development Corporation, The Gowanus Dredgers, and Community Board 6, have all
expressed concern with the proposal, lending to the social indecision with the redevelopment and clean up of the site. Residents in
the area remain concerned the proposed plan does not directly address the issue of clean-up or the associated cost. Additionally, the
current plan does not address the pollution in the canal itself including the on-going pollution due to the combined sewage overflow
system (CSO) in conjunction with the currently defunct "Flushing Tunnel". This continues to be a point of contention among the
various groups associated with the canal. Compounding the issue is the proposal to designate the entire Canal as a "Superfund" site,
which could jeopardize current development proposals. However, the clean up of individual sites creates a situation in which "spot
clean-up" occurs. Meaning if 'Site A' is cleaned while 'Site B' an adjacent site is not, there is the potential for leeching to continue as
the chemicals move through the soil and along the water table. Studies of the sites including historic business use of the canal begins
to reveal the potential chemicals and materials which may still be present on site. The chemical make-up of these materials falls into
one of these categories: Light Non-Aqueous Liquids, Dense Non-Aqueous Liquids (DNAPL), or Heavy Metals.
While these pollutants have methods of remediation they need to be associated with a comprehensive strategy allowing for a
successful remediation. This comprehensive strategy must address the environmental, economic, and social components. This
project looks to accomplish this by developing a remediation infrastructure.
Project Goals & Objectives
The project's goal is to create a remediation infrastructure for the Gowanus Canal. This will be accomplished by taking an analytical
"bottom-up" approach to design. Using environmental, social, and economic criteria as a basis for analysis the objective is to
develop a tool that will provide a comprehensive understanding of the site, organize and align community interest groups, and assist
in the development of solutions for the remediation and future redevelopment of this site.
Environmental & Social Data Collected & Analyzed
Environmental mapping on both the local scale and case-study scale includes: hydrology, topography, tidal flood areas, flood plains,
storm surge, watershed, combined sewage overflow, local collection networks, possible toxins, contaminated sites, land use, and
designated brownfield sites mapping. Project area Local-Scale social data collected includes: information on local community boards,
independent neighborhood preservation non-profit groups, 'grass root' (volunteer) neighborhood groups, and community planning
areas. A sampling of current development proposals and initiatives were studied at both a local scale and case-study scale. Historic
land use designations were reviewed using current business type charting and historic maps showing former land use and business
types to determine possible incompatible land use conditions. Site visits and interviews with neighborhood residents were also
conducted. A survey of local residents was performed to analyze the community perception of the site as well as to gauge local
interest and expectations for the site. A local documentary was also reviewed for information pertaining to the history of
development proposals over the years and previous failed attempts to redevelop the site.
Methods of Analysis
The analysis process began with environmental mapping and data collection. These maps were used to develop a complete
understanding of the over all site conditions. The next phase of the process involved the development of a Matrix. The Matrix served
as the organizational component for creating a variety of remediation systems. These systems were then mapped out to study
possible links created by the systems in turn developing a framework for remediation networks. The remediation networks were
then analyzed as case study sites to further develop an understanding for the design and implementation process.
How Options were Considered
At the case-study scale consideration to the deployment of remediation tactics was given to proposed redevelopment and rezoning
plans in conjunction with current and historic land use data collected. Additionally, site contaminate types and locations where used
to determine best practices for remediation. Community concerns, environmental conditions, and restoration of ecologic systems
where also used in the development of the social, environmental, and economic determinants.
How Interested Parties were Involved
A variety of parties and stakeholders are involved in the redevelopment of this area. However it is not entirely clear what political
mechanism is overseeing the process. Community stakeholders and other parties were interviewed as a component of this project
however the product here has not been presented formally to these groups. The premise of this project has been discussed
informally with a several key players and the intent would be to present this analysis and the associated matrix for consideration as
a tool to drive the remediation process of the site.
How Design was Used in the Process
The Matrix helped to develop a clear analytic approach to organizing determinants and tactics and possible applications. Design at
the case-study scale was used to aid in understanding possible sites and deployment methods. This design also drove the process by
highlighting opportunities for a multi-scale approach for deployment of the various tactics while providing a clear understanding of
the intrinsically linking networks of remediation.
How the Project Would be Implemented
The introduction of the Matrix as a tool would begin the discussion uniting and organizing concerns allowing for the evolution of
remediation tactics for the site. This would generate a framework for the development of remediation tactics and deployment
methods. As these multi-scale tactics are deployed a system of networks would be generated. These networks would become a
remediation infrastructure for the site and the comprehensive plan for redevelopment.
How the Project Could be Administered and Monitored
An analysis of precedence projects, including IBA- Emscher Park and the Lake Ontario Waterfront- Regeneration Trust, provide an
understanding of the essential nature of a political mechanism in conjunction with an organizing element for administration and
monitoring such projects. A political mechanism would be proposed in conjunction with the use of the Matrix as tool for future
success in developing a remediation infrastructure.
"The remediation infrastructure is fantastic. This project got into the actual small-scale problems and connected them in a believable
way. We liked the way they included gradations, not just black and white solutions. We could see this presented at planning
commission meeting."— 2009 Student Awards Jury
