Sustainable brownfields redevelopment and empowering communities to participate more effectively in environmental decision-making

The mitigation and reuse of contaminated land is a central element of environmental risk management practice in high-income nations. In the United States, with approximately 1500 Superfund sites (National Research Council, 1991), over 400,000 hazardous waste sites (Environmental Research Foundation, 1993) and an indeterminate number of sites that are qualitatively less contaminated, generally known as 'brownfields', there is ample opportunity for environmental professionals interested in becoming actively involved in such work. The reuse of previously developed plots of land is an important environmental risk management strategy as well as a primary trajectory for advancing communities through local decision-making that seeks economic, aesthetic or recreational advantages. This edition of Local Environment will explore this topic from a variety of perspectives.     

Revitalizing neighbourhoods through sustainable brownfields redevelopment: Principles put into practice in Bridgeport, CT

This article chronicles activities and approaches carried out in working with community partners and public and private stakeholders in advancing revitalization within Bridgeport, CT. The approach described utilizes brownfields redevelopment as a focal point for a stakeholder process whose goal is neighbourhood revitalization. Two neighbourhoods—the Went End and East End—are the focus for major stakeholder-driven brownfields redevelopment processes. The article defines key elements of the stakeholder process including: involvement at several levels from neighbours to the site to the Mayor's office and beyond, a risk communication process that incorporates the broad concerns of the stakeholders including crime and violence, and the need for ongoing oversight and management throughout the redevelopment process.     

Understanding brownfields regeneration in the US

Federal, state and local initiatives have emerged in the United States over the last decade to address the increasing number of 'brownfield' properties that are perceived to be contaminated. These initiatives are based on the beliefs that the social and financial benefits provided by redevelopment exceed the costs imposed by the interventions and that the reuse of sites can further local sustainability objectives by reducing growth pressures in undeveloped areas. This paper provides an examination of the current state of the practice of brownfields within which these interventions should be based. We summarize brownfields problems and federal, state and local efforts to address these problems. We then present ten stylized propositions about brownfields and draw on a range of surveys of the public and private sectors and other sources to explore the reality behind these. Finally we use the propositions to tie brownfields regeneration to sustainable local development through an area wide approach to redevelopment rather than a site base approach which benefits a wider community or geographic area.     

Incentives for private residential brownfields development in US urban areas

Public agencies in the US have committed resources to encourage private investment in reusing contaminated sites. With public funds in short supply, the effectiveness of their efforts matters both to the agencies and the development community. This paper draws on a mail survey of private developers that uses conjoint choice experiments to investigate the relative attractiveness of incentives to promote residential infill on contaminated property. Results suggest protection from third party liability offers the most value, with protection from cleanup liability and relief from public hearing requirements also important. The findings indicate several opportunities for planners to promote infill on contaminated sites in a socially and environmentally appropriate manner.     

The greening of brownfields in American cities

The redevelopment of brownfields has become a central component of government efforts to revitalize many US cities. While the focus of these efforts has concentrated on promoting industrial and commercial redevelopment, some cities have started to also consider converting brownfields into parks and open space as part of a more comprehensive renewal strategy. Based on a survey of 20 case studies, this paper identifies and discusses: (1) the primary issues involved in brownfield greening projects; (2) the benefits of such projects; and (3) the specific planning processes involved. The overall conclusion drawn from the survey is that numerous renewal‐oriented benefits can ensue from greening projects, if there is extensive stakeholder commitment devoted to deal with its financial and development‐oriented challenges.     

Promoting community involvement at brownfields sites in socio-economically disadvantaged neighbourhoods

Brownfields programmes provide environmental justice to distressed communities by applying private sector remediation and real estate expertise to abandoned and contaminated properties. This study examines how brownfields developers and community support organisations operating in socio-economically disadvantaged neighbourhoods work to increase awareness of projects in the community, build trust between stakeholders and create mechanisms for community members to participate in brownfields decision making. Analysis of case study data from brownfields sites in four US cities shows that developers and non-governmental organisations can play important roles in fashioning redevelopment outcomes which benefit both developers and communities. When standard required outreach efforts are combined with non-traditional community involvement mechanisms, the result is often long-term support for redevelopment projects.     

Comparing contaminated property redevelopment for mandatory and Voluntary Cleanup Programs in California

This study uses California data to compare redevelopment for properties subject to mandatory and voluntary cleanup. CalSites are subject to the CERCLA liability approach, while properties in the Voluntary Cleanup Program (VCP) are subject to a risk-based approach (RBA) that allows some contamination to remain for non-residential redevelopment. The expectation is that VCPs will show a greater proportion of industrial redevelopment, which has the least stringent standard, and a smaller proportion of residential redevelopment. The results show an overall trend toward more residential redevelopment of contaminated properties, but consistent with expectations, the trend is weaker for VCP properties than CalSites.     

Opportunities for landowner participation in local planning

Much has been written on public participation in local planning but very little on the involvement of landowners. This is despite the clear financial motives which encourage many landowners to participate in the local planning process. The paper demonstrates how in one case in West Yorkshire, an important historic landowner was able to exert a substantial influence on the pattern of land use allocations in an adopted local plan. Although the particular characteristics of the case study may not be found elsewhere, it helps to identify how more substantial research in this often neglected area might proceed.     

Brownfield redevelopment as a smart growth option in the United States

An evaluation is made of brownfields redevelopment as a smart growth policy compared to purchase of land, restrictive growth policies, changing transportation patterns, promoting compact development designs on the metropolitan fringe, and regional government. In the US brownfields redevelopment has clear advantages with regard to environmental protection, moral imperative, and government and special interest reactions. Its rank with regard to economic feasibility, ability to respond to changes in technology, and public reaction are not clear. A great deal more research is needed, especially about the costs of brownfield redevelopment and public preferences for housing type and location to be certain about brownfields redevelopment as a viable smart growth option.     

Alternatives for private participation in the provision of water services

Recent years have seen a region-wide movement throughout Latin America and the Caribbean toward wider private participation in the provision of infrastructure, as well as in other public services. This paper discusses the possible benefits from the privatization of water services and illustrates the range of alternatives available for private participation in their provision. These alternatives are analyzed and their possible application in Latin America and the Caribbean is assessed on the basis of examples from the region and other parts of the world. However, the paper does not discuss, in any detail, the theoretical justifications for the movement back to a market system in the provision of public services.     

Government participation in mining projects

Governments of developing countries may obtain ownership participation in national mining projects in the hope of receiving greater policy control over, financial rewards from, and information about such projects. These objectives could be achieved by using their sovereign authority to tax, regulate and monitor projects more effectively. The principal problem is likely to be the administrative inability fully to enjoy rights that they lawfully possess. As such projects are nearly always controlled by foreign entities, and involve the exploitation of irreplaceable mineral wealth, they may engender feelings of suspicion and hostility. Government participation may sometimes be necessary to mitigate those feelings and to lead to more stable and successful projects. If these political objectives are fully recognized, then government participation may be structured so as to minimize any detrimental effect it might have on the fiscal and financial structure of the project. It may also prove to be a vehicle for future participation by private local interests, thereby eliminating the alien enclave feature generally characteristic of such projects.     

Utility participation in a multispecies plan

Single-species listings under provisions of the federal Endangered Species Act (ESA) have caused, or have been accused of causing, significant regional economic impact. In an attempt to avoid such adverse effects on regional economic development, the state of California passed the Natural Communities Conservation Planning Act (NCCP) in 1991. It is a voluntary, consensus-based approach to balancing protection of sensitive biota and biodiversity with regional economic development. The pilot NCCP program for the conservation of several threatened, endangered, and category 1 species, plus an additional 35 coastal sage scrub-related species in southern California, was completed and submitted to the public for review and comment in December 1995. This program proposes the voluntary establishment of a 86,600-ha multispecies reserve system. Once completed, participating landowners will receive ESA Section 10(a) incidental take permits for present and identified future projects. Utility rights-of-way are incorporated into the program as important connective linkages between reserve units and other adjacent important habitat areas. All data and information regarding the proposed results of the NCCP are subject to change pending agency response to public comments on the draft Habitat Conservation Plan and joint EIR/EIS.     

Public participation in plastics recycling schemes

Without public contributions, recycling from domestic waste would not be possible. In order to support recycling projects it is important to try to understand who recycles, how they recycle, and why they recycle. This paper presents the results of a structured survey of 500 members of the public served by schemes to collect plastics waste for recycling. Data were gathered on the characteristics, behaviours and motivations of recyclers. The authors also sought to discover how the public perceive plastics compared to other materials, and as a recyclable material. Responses were collected in such a way that the awareness of the recyclability of materials could be compared with the recycling behaviour of respondents. An element of comparison was introduced between those served by a system of bottle banks (bring scheme) and those covered by a household collection (collect scheme). The survey results are reported and their implications for the management of post-consumer plastics waste collection schemes are discussed.     

Utility of interactive computer-based materials for enhancing public participation

Citizen involvement in environmental policy setting is important for insuring policy viability. However, traditional public meetings are criticized for being an ineffective means of conveying information, especially for complex policy issues such as watershed management. An interactive technology-based approach to public meetings provides a promising alternative. This pilot study compares knowledge, commitment and satisfaction levels of two groups of participants at a watershed meeting: one group attended a traditional meeting format and the other attended a technology-based format. Group survey results show technology-based participants report a higher level of meeting satisfaction and a stronger influence of the meeting on watershed attitudes. Comparisons of knowledge and commitment levels may require a multiple meeting format to highlight group differences.     

Environmental accounts for households: A method for improving public awareness and participation

Recently the European Council agreed on a CO₂ reduction target of 10% by the year 2010. In accordance with this, Denmark decided to reduce its CO₂ emissions by 25% over the same time period. One important element of both the European and Danish agreements is energy saving in industries and in private households. Typically industries and private households are also expected to participate in other kinds of environmental improvements, e.g. waste treatment. Such improvements in environmental performances are normally accounted for. In industry, for example, green accounting or environmental auditing are techniques used to measure progress in environmental performance. But when it comes to the environmental performance of people or households very few book-keeping principles have been developed. This paper describes a Danish share-housing project's efforts to formulate an environmental policy and outline an environmental accounting system which can keep track of a household environmental record. It describes the environmental accounting methods, the results and experiences from its first five years.     

Towards an ecologically meaningful classification of the flow biotope for river inventory, rehabilitation, design and appraisal purposes

Recent research into the physical and ecological status of rivers has focused upon rapid field-based assessments of mesoscale habitat features in order to satisfy international regulatory requirements for habitat inventory and appraisal. Despite the low cost and time efficient nature of rapid field surveys, the robustness of such techniques remains uncertain. This paper uses data from over 4000 surveyed UK river reaches in the UK River Habitat Survey (RHS) database in order to seek linkages between surface flow conditions (flow biotopes), local channel morphology (physical biotopes) and biologically distinct vegetative and minerogenic habitat units (functional habitats). Attempts to identify one-to-one connections between surface flow types, units of channel morphology and functional habitats oversimplify a complex and dynamic hydraulic environment. Instead, a nested hierarchy of reach-scale physical and ecological habitat structures exists, characterised by transferable assemblages of habitat units. Five flow biotopes show strong correlations with functional habitats, and differing combinations of three of these account for over 60% of the distribution for all functional habitats. On this basis, a classification of environments for ecological purposes is proposed. Principal components analysis and agglomerative hierarchical clustering analysis are employed to objectively validate the proposed classification. Flow biotope assemblages may also represent reach-scale channel morphologies (step-pool, riffle-pool and glide-pool), although functional habitats exhibit differing 'preferences' for rougher or more tranquil environments within these. While the data and analysis are specific to the UK RHS, the methods and findings have wider application in situations, where rapid field appraisal methods and associated databases are deployed in water resource inventory and river rehabilitation design.     

Use of the Delphi in a citizen participation project

A Delphi survey, the Dade Toxics Community Assessment, was used to develop a consensus between citizen and professional members of the Dade TOXICS Task Force, as a part of a public participation project in Dade County, Florida. The results showed an agreement between the two groups on the ranking of the five major problems to be studied by the task force.     

Facilitating and evaluating public participation in urban parks management

Active citizen involvement is driven by assumptions about inclusivity, equity and fairness and as such is part of an agenda for devolving power, largely from local authorities to individual persons or groups. Few theorists and practitioners doubt the benefits of such deliberative involvement but there is, as yet, little guidance on how to initiate, establish and support individual groups, nor how to evaluate their processes and outcomes. This lack of guidance often leads to groups being inadequately or inappropriately supported which, consequently, reduces their ability to engage in the very local political processes that they were initiated to address. This paper offers a new approach to the creation and support of such groups and outlines the design of two participation evaluation matrices, one to monitor the process and one to evaluate the outcome of the participatory exercise, providing a valuable feed-back tool for participants and facilitators. The paper concludes that it is important to have the financial commitment and willingness of the local authority to recognise public involvement as an educative process, to empower people and to allow groups to develop and own their achievements.     

Community participation in the planning and management of cultural landscapes

The maintenance of valued landscapes often requires the active collaboration of local communities in their planning, management and sustainable development. This paper examines a variety of situations in which local stakeholders have actively participated in the protection and maintenance of ‘cultural’ landscapes. It reviews and interprets evidence on the ways in which central and local governments, non‐governmental organizations, interest groups and the wider public can collaborate in planning and managing cultural landscapes. Particular attention is given to: the role of stakeholders, participation by communities‐of‐interest and communities‐of‐place; the management of specific landscape features; and policy and funding frameworks. It is concluded that community‐based initiatives are unlikely to substitute for formal management of extensive protected areas, but that participatory approaches can be effective in more targeted situations.     

Salt river project's participation in Arizona's bald eagle conservation efforts

Bald eagle (Haliaeetus leucocephalus) conservation in Arizona, USA, is a prime example of a successful, cooperative environmental management effort. The Salt River Project (SRP) is an active participant in the statewide bald eagle management activities. This paper summarizes the major components of the statewide program and highlights SRP's participation in these efforts. The Southwestern Bald Eagle Management Committee (SWBEMC) was formed as a means of coordinating interagency projects. Chaired by the Arizona Game and Fish Department (AGFD), the SWBEMC is comprised of 15 state, federal, tribal, and private agencies. Together, these agencies sponsor the Nest Watch Program, a unique and effective program dedicated to the study, conservation, and recovery of bald eagles in the southwest. Other significant components of the bald eagle management program include nest monitoring, nest search activities, winter counts, and demography studies.
