What is Brownfield and Infill Development?
The reuse of urbanized brownfield and infill sites utilizes existing infrastructure and maximizes the value of existing resources. Brownfields consist of properties whose expansion, redevelopment, or reuse may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. These properties include sites with historical use as an industrial or commercial site and are often located in urban areas. According to the NJ Department of Environmental Protection (NJ DEP), there are an estimated 10,000 brownfield sites located throughout the state. Of the more than 10,000 sites, some 2,544 acres of brownfields fall into 267 sites that the NJ DEP calls Brownfield Development Areas (BDAs). The NJ DEP has designated BDAs in communities that are affected by multiple brownfield sites in need of remediation. The BDA Initiative, a program of the NJ DEP, assembles large parcels of brownfields and coordinates clean up and redevelopment efforts to elicit a more significant impact environmentally, economically, and socially.
Once remediated, these sites find a reuse for any type of development, from parks and housing to new commercial and industrial development. As New Jersey reaches build-out, redeveloping brownfields emphasizes the benefit of maintaining undeveloped lands for use as farmland and open space – recognizing that diverse landscapes build value for the developed environment. Brownfield redevelopment revitalizes urban areas, improves adjacent property values and adds to the overall quality of life for residents and the community.
Redevelopment of brownfields and infill development in existing developed areas provides opportunities for alternative transportation such as walking and bicycling and can reduce reliance on the automobile as a mode of transportation (see Alternative Transportation and Transit Oriented Design). These sites gain value by locating in areas of existing infrastructure (i.e., public transportation, water, sewer, electricity). For developers, there are numerous incentives to redevelop these sites, offering compelling benefits for investors as well. As a community benefit, redevelopment restores economic and social value to the surrounding neighborhood adding value to the community at large.
How to Develop Brownfield and Infill Sites
Conducting an initial investigation of a brownfield site indicates the level of contamination on the property – and the level of cleanup required. This phase is often inexpensive and is a common element of due diligence in real estate development. It is important to realize that many brownfield sites are minimally contaminated, and it may be inexpensive to neutralize or stabilize the site. New technologies, such as the Triad Approach, assess a site both speedily and comprehensively – two significant issues of concern to investors and developers. The Triad Approach focuses on three main principles and uses real-time environmental sensors:
- Systematic Project Plans
- Dynamic Work Strategies
- Innovative rapid sampling and Analytical Technologies
New residential developments, especially single-family residential developments, are subject to strict cleanup measures. Developers may also want to consider planning a mixed-use development.
To pursue the development of new residential construction on a contaminated or brownfield site, the developer may follow these steps:
- Gain local support – speak with local zoning officials, planning officials, or community development department to confirm that the redevelopment plan is within the community’s neighborhood plan. Make sure to address the following questions: 
- Is the brownfield or contaminated site located within a BDA?
- How is the parcel or area zoned according to municipal zoning ordinance?
- Is the proposed end-use consistent with the municipality’s master plan? If not, would they accept an end-use change?
- Gather community input – consult with the community and foster support for the project. Depending on the size of the site to be developed, host a public hearing.
- Consult with the Brownfields Interagency Team (BRIT) of the NJ Department of State’s Business Action Center. BRIT brings together over a dozen agencies that may be relevant to a redevelopment project, including departments that offer financial incentives.
- Find an appropriate site – New Jersey Brownfields Site Mart is an online searchable database of brownfield properties. The Location Assessment tool allows searching by land characteristics, demographics, and economic opportunity zones for any address in New Jersey. Additionally, check the NJ DEP’s Known Contaminated Site Report, which is more exhaustive. Known contaminated sites may be appropriate for redevelopment and eligible for incentives.
- Hire a Licensed Site Remediation Professional (LSRP)To oversee the clean-up process – The LSRP assists in conducting a preliminary assessment, site investigation, remedial investigation, and creation of a remedial action work plan by the Brownfield and Contaminated Site Remediation Act. The preliminary assessment is critical because a brownfield, by definition, does not necessarily have contamination. Instead, it “is perceived to have contamination.” As a result, some designated brownfields may require little or no clean-up effort and may not be costly.
- Investigate obtaining environmental insurance.
- Engage the services of an environmental or redevelopment attorney. These professionals support the developer in understanding their liability and obligations once they have acquired a contaminated site.
- Research funding sources and incentives and additional resources through the NJ Department of State’s Office of Business Advocacy
Leveraging $6.2 million in state and federal funding, the city of Elizabeth was able to identify, remediate and develop ten contiguous contaminated sites in the Elizabeth port neighborhood. In addition to an initial grant from the EPA, sources of funding included the NJ Redevelopment Authority, the City of Elizabeth Home funds, the State of New Jersey Low Income Housing Tax Credit Program, the New Jersey Balance Housing Program, NJRA Brownfields Remediation Program, and the State Urban Enterprise Zone. The city hired Brand New Day, Inc., a local nonprofit housing developer to construct a 35-unit affordable housing development.
Saves on infrastructure costs/Utilizes existing infrastructure
Brownfields, vacant or abandoned property, or underutilized parcels, are often located in dense urban areas near mass transit and other existing infrastructure, helping to avoid costs of building new utilities, roads, and other expensive infrastructure. Existing infrastructure also reduces the amount of land disturbance necessary for a project.
Saves on land costs/Increases property values
Brownfield sites, vacant or abandoned land, or underutilized property, can have substantially lower property costs than other properties, offsetting the cost of assessment and remediation. Due to low initial cost, property value can increase significantly after redevelopment. Also, the surrounding property values can increase by addressing brownfields and vacant or underutilized parcels in the area. According to the US EPA, addressing nearby brownfields can increase residential property values by 2 to 3 percent.
Enjoys significant incentives
The State of New Jersey has created multiple funding streams for brownfield development that may be available to developers. The Office of Brownfield Reuse administers the Hazardous Discharge Site Remediation Program, the Brownfield Reimbursement Fund Program, and the Landfill Redevelopment Program. Federal tax incentive certifications may also be available. Incentives and programs are subject to change. To determine what incentives are available, developers should meet with a representative from the NJ Brownfields Redevelopment InterAgency Team.
The New Jersey Hazardous Discharge Site Remediation Fund (HDSRF) created a partnership between the NJDEP and New Jersey Economic Development Authority (NJEDA) to provide remediation funding for innocent purchasers. An innocent purchaser is an individual who, “by an honest agreement, buys property in the absence of sufficient knowledge to charge him or her with notice of any defect in the transaction.”
New Jersey designates Brownfield Development Areas (BDAs) in areas of planned redevelopment and existing brownfield sites. This competitive process provides management, technical and financial assistance. The BDA Initiative provides “funding to public entities (municipalities, counties, and redevelopment agencies), qualifying private entities (businesses, corporations, homeowners) and non-profit organizations for the investigation or remediation of a suspected or known discharge of a hazardous substance.”
The Brownfield Reimbursement Program reimburses developers up to 75 percent of remediation costs based on new taxes developed from the brownfield project.
The US EPA also funds assessment, cleanup for brownfield sites and provides technical and financing information (http://www.epa.gov/brownfields/grant_info/index.htm).
Creates density and improves existing markets
Due to the location of most brownfield sites, there is the benefit of being close to existing markets. The same is true when pursuing infill development within already developed areas. Urban areas provide the necessary density that other areas cannot for certain types of businesses. Locating a business near an existing market or in a densely populated area can ease the costs of remediation, alleviate the higher cost of land in an urban area as opposed to a greenfield, and limit the costs associated with marketing and attracting business.
Revitalizes urban/former industrial areas
Cleaning up brownfield sites or redeveloping vacant, abandoned, or underutilized land can revitalize urban areas. By promoting infill and creating denser walkable communities, cities can improve the sense of community among residents.
Removes hazardous material from soil and groundwater and protects human health
Many brownfield sites contain some level of a contaminant in the soil. These contaminants can be harmful to human and environmental health for the surrounding area. Rainfall can transport pollutants into groundwater and negatively impact downstream sites. Brownfields can pose a health risk to the people living nearby and to waterways in the area or downstream. Remediating and stabilizing these sites can improve overall environmental quality and avoid potential environmental and human health risks (see Soil Test).
As of May 2017, assessment grants and other EPA Brownfields grants have contributed more than 124,759 jobs and $24 billion of public and private funding for brownfield and infill development. On average, $16.11 was leveraged for each EPA Brownfields dollar and 8.5 jobs leveraged per $100,000 of EPA brownfields funds expended on assessment, cleanup, and revolving loan fund cooperative agreements. Also, finding uses for vacant, abandoned, or underutilized properties can create jobs both in the development of the project and afterward. Since these are in dense urban areas, developing mixed-use buildings on these sites can generate jobs even after the construction phase of the project.
Builds public support
There is often strong public support to remove brownfield sites and the potential health risks they might pose. Also, vacant, abandoned, underutilized land can bring down property values in the area and residents are often in favor of addressing these issues and improving the aesthetics of the community.
Benefits to Water Quality, Air Quality, and Lower Traffic Congestion
US EPA estimates that redevelopment projects can reduce stormwater impacts, especially if the redevelopment project incorporates green technologies, such as green roofs, stormwater harvest and reuse systems, and landscaping elements such as bioswales and rain gardens (see Vegetated Roofs and Rain Gardens).
By promoting development near existing infrastructure and services, brownfield and infill development can improve air quality by creating denser, pedestrian and bicycle-friendly communities (see Active Living). In denser, urban areas people are more likely to walk, thus reducing traffic congestion, improving overall air quality, and improving public health by encouraging residents to walk.
The cost of brownfield remediation varies substantially, depending on the extent of the contamination and the intended reuse. Because a brownfield is considered a site that may be contaminated, a remediation investigation may reveal limited contamination, in which case, the remediation cost is minimal. In cases where a heating fuel tank was buried and leaked, the damage can be extensive, but, again, may be relatively inexpensive ($10,000-$100,000).22 For more complex sites, which have multiple contaminants and higher levels of contaminants, costs can run in the millions.
A significant area of cost is that of uncertainty. In instances where the property has been in industrial use for many years, there could be contaminants that predate any tracking systems, making them difficult to anticipate and requiring more than one investigation. Triad is a recommended program because it fully characterizes the extent and type of spill all at once, whereas traditional approaches tested where they expected to be the extent of contamination, and, if they were wrong, had to go into the field a second time and test again. In some instances, these repeat tests could delay projects by months. Though Triad is more expensive initially, for complex sites where there is an extensive industrial history, it can expedite the clean up significantly. The level of cleanup required also determines the cost. In New Jersey, non-industrial cleanup requirements (such as would be required to build housing on a previously industrial property) must meet a higher standard than a cleanup for a property that returns to industrial use. Depending upon the project, some developed brownfield sites require ongoing monitoring by a responsible party as determined.
Brownfield reuse offers multiple environmental and resiliency benefits by reducing the number of impermeable surfaces in a given area, especially by preserving open space and park space, often lacking in many residential areas across New Jersey. Instead of developing existing greenfields which can be critical natural habitats and create more stormwater runoff (through higher levels of asphalt, concrete, and other impermeable surfaces), brownfields use existing, impermeable sites.
Redeveloped brownfield sites can serve as an emergency headquarters or storm shelter in underserved areas that could house mobile assistance; for example, serving as a location for food trucks or mobile health services. Other reuse may include warehouses with solar panels for backup power generation, or broadband and wireless access to support communications/dispatch mobile services.

 Restrictions apply to the end use of a partially remediated site. While some restrictions may be allowed on residential uses, the NJ DEP does not like to see restrictions on single-family residences. For example, contamination capped with soil restricts residents from digging in the yard, placing a more substantial burden for single-family homeowners compared to townhomes or multi-family properties managed by a property management group. To determine the level of clean up necessary for the end user, developers work with a Licensed Site Remediation Professional (NJ DEP, 2010).
 A mixed-use development incorporates multiple uses within a building or neighborhood – a green building practice that places housing within walking distance of commercial and recreational activities. However, mixed-use developments on brownfields cause complications because commercial and residential uses require different cleanup measures.

 Answering these questions helps determine available incentives.
 In New Jersey, the Site Remediation Reform Act (SRRA) (2009) outlines how remediation takes place on contaminated sites. Under the SRRA, approval is not required by the NJDEP before beginning the remediation process. However, when the SRRA became fully active in 2012, any remediating party was required to use a Licensed Site Remediation Professional (LSRP) and must start the cleanup without NJ DEP approval. The SRRA established the LSRP program. Qualified professionals receive a license from an LSRP Board to conduct remediation of sites in New Jersey.
