Stack and Sequence: Building a Capital Matrix for Brownfield Redevelopment Funding
Brownfield Process & Funding
1:45 PM – 3:45 PM
Community Hall BC
Every brownfield project requires multiple sources of capital to be successful and the more difficult the project, the more capital sources are needed. This workshop will identify and describe a wide variety of brownfield capital sources that will range from brownfield-specific funding to traditional redevelopment financing. A deeper dive will show how sources can be integrated and stacked, used sequentially for the various stages of redevelopment, and combined with private investment. This workshop offers more than just a list of capital sources: in the first half of the workshop capital sources will be described and presented in a “generic” matrix showing the stack and sequence possibilities. Then in the second half of the workshop we’ll collectively work through a few stack and sequence project scenarios to demonstrate the wide range of possibilities for brownfield redevelopment funding/financing programs. The workshop will accommodate individual sites as well as broad areas, and both urban and rural scenarios. Public agencies and non-profits will benefit by learning how to best promote redevelopment through utilizing multiple capital sources. Additionally, practitioners will gain insights, tools, and strategies for working with developers and investors and cultivating successful public-private partnerships that support communities’ neighborhood revitalization goals. All participants will come away with a greater understanding of the wide variety of brownfield redevelopment capital sources and will have the opportunity to create their own plan.

West Sacramento 20 Years Later – A Vision Becomes Reality
Brownfield Process & Funding
10:45 AM – 11:45 AM
Community Hall BC
For over 20 years, West Sacramento has been a prime example of actively preparing and implementing a Redevelopment Plan for various City Districts. From Master Plan to Redevelopment Transition Plan to Plan execution, West Sacramento has been at the forefront of Brownfields Redevelopment, using a variety of Financing and Funding resources, including EPA Assessment and Multi-purpose Grants, Tax Increment Financing (TIF), as well as public-private partnerships to help transform a once-overlooked City along the Sacramento River into a highly desirable place to live, work and visit. The session will describe the City’s visioning, financing and funding, assessment, and revitalization process used to transform key target areas such as Pioneer Bluff, Stone Lock and the Capitol Avenue Districts. West Sacramento is a prime example of Brownfields Redevelopment planning and execution. Examples of this transformation are evident across the City (Pioneer Bluff deindustrialization, Stone Lock rehabilitation, and affordable housing developments in the Capitol Avenue District). Attendees will gain a better understanding of full scope redevelopment projects from visioning to execution, the creative financing and partnership building needed to effect such a transformation, and the inspiring story that is West Sacramento. This session is intended for all CCLR CALRC attendees and will cover visioning, financing and funding, regulatory agency collaboration, environmental considerations, and stakeholder consensus building. Attendees will also view a GIS-based Story Map which graphically captures the West Sacramento transformation, past, present, and future.

The U.S. Environmental Protection Agency announces it is lowering recommended screening levels and strengthening guidance for investigating and cleaning up lead-contaminated soil in residential areas. This is the second time that EPA has reduced the screening value for lead in soil at residential properties. The original screening level range of 500 to 1,000 parts per million (ppm) was established in 1989. The original screening value was reduced to 400 ppm in 1994.
As a result of lower screening levels, EPA expects to investigate more residential properties for potential cleanup under the Superfund law and the Resource Conservation and Recovery Act. Today’s action delivers on the Biden-Harris Administration’s ongoing commitment to protect communities from lead poisoning, particularly in disadvantaged and overburdened communities facing multiple sources of lead exposure, advancing President Biden’s environmental justice goals.
EPA is lowering the screening level for lead in soil at residential properties from 400 ppm to 200 ppm. At residential properties with multiple sources of lead exposure, EPA will generally use 100 ppm as the screening level. Screening levels are not cleanup standards. EPA aims to help site teams make site-specific cleanup decisions to protect nearby communities; EPA makes cleanup decisions specific to each site, using site-specific factors, including risk factors and community input that can vary from site to site.
While the guidance goes into effect immediately, EPA welcomes feedback from the public for any future updates to the guidance. Please submit written feedback on the guidance in the public docket (Docket ID: EPA-HQ-OLEM-2023-0664) for 60 days, from January 17, 2024, to March 17, 2024.
For more information or implications for a site, visit the updated guidance webpage, or contact an SCS environmental professional in your state.
The contaminated site rehabilitation (cleanup) provisions promulgated in Florida are based on Risk-Based Corrective Action (RBCA) principles. This approach to rehabilitating sites combines traditional site assessment with risk assessment principles and site-specific conditions to develop risk management options (RMOs) that meet the client’s objectives and the mandated human-health risk levels. RBCA allows us to tailor our assessment and remediation strategies to the unique characteristics of each site and avoid costs associated with unnecessary environmental assessment or remediation.
The RBCA provisions offer a number of default RMOs to achieve site closure. The most commonly used RMOs include natural background evaluations, total recoverable petroleum hydrocarbon fraction analysis, and synthetic precipitation leaching procedure (SPLP) analysis. One of the lesser-used RMOs includes calculating alternative soil cleanup target levels (ASCTLs) using site-specific soil properties. A downside of this approach is that one of the input parameters, soil moisture content, requires one year of data collection; this is too long for most of our clients (particularly developers). Nevertheless, given the right conditions, this RMO can yield beneficial results by justifying a higher cleanup level without needing a year of data. An example of how SCS has used this approach is below.
Background – SCS calculated a leachability-based ASCTL using site-specific soil properties for a former agricultural site undergoing redevelopment for residential use. We considered this site to be a good candidate for this RMO due to the following site-specific conditions:
Data Collection – SCS collected discrete samples from the relevant intervals to obtain site-specific data for the required soil properties. The measured parameters include a fraction of organic carbon, dry soil bulk density, and soil moisture content. Using these measured parameters, SCS calculated the remaining site-specific soil parameters, specifically, the water-filled soil porosity, total soil porosity, and air-filled soil porosity.
ASCTL Calculation – We calculated the ASCTL using the site-specific soil properties and the equation below. The table following the equation presents the default and site-specific soil property input values and the method for deriving the site-specific values. Refer to the DERM Technical Report: Development of Cleanup Target Levels (CTLs) for Chapter 24, Miami-Dade County Code (September 2005) for information concerning the remaining input parameters.

Using the site-specific soil properties resulted in an ASCTL of 0.046 mg/kg, significantly higher than the default leachability SCTL of 0.002 mg/kg.
Sensitivity Analysis – As mentioned above, soil moisture content requires one year of data collection; generally, this parameter is an average of results obtained from four quarterly events (designed to represent variability in moisture content during wet and dry seasons). Since we speculated that organic carbon content is driving the ASCTL, and the client could not wait a year to get approval of the ASCTL, SCS performed a sensitivity analysis of the various soil parameters on the ASCTL calculation. The results indicated that soil moisture content does not impact the ASCTL calculation for dieldrin (at the site-specific organic carbon content), even using the unrealistic scenarios of 0% and 100% soil moisture content. With this finding, we could justify using a single data point for soil moisture content instead of averaging one year of soil moisture data.
Summary – ASCTLs using site-specific soil properties can be calculated for any COC. However, consider several criteria when evaluating the feasibility of this approach, some of which include:
We can also calculate the direct exposure ASCTLs based on site-specific soil properties. Use the soil properties in the volatilization factor portion of the direct exposure SCTL equation; therefore, COCs with a significant fraction of the risk associated with the inhalation route would benefit most from this RMO.
Ultimately, an environmental professional with expertise in environmental assessment, risk assessment, and soil science/geology can help assess whether calculating an ASCTL would be beneficial in meeting your client’s goals. Approval of a higher leachability-based ASCTL can result in significant savings by minimizing or eliminating the need for additional assessment, remediation, or groundwater monitoring.
