Open up more possibilities!


With the new available housing supply critical in San Diego and across the country during the current housing crisis, affordable housing options for low-income people in need are more important than ever. Below are several examples of recent Brownfields projects that have been or are under development by affordable housing developers to benefit the critical needs of the developmentally disabled and seniors.

SCS Engineers Environmental Consulting and ContractingMercy Housing, Villa de la Vida – Mercy Housing Corporation (MHC) redeveloped a creek-front Poway site with multiple former leaking underground storage tanks (USTs) into Villa de Vida, a home for adults with developmental disabilities. The site had been historically used as a San Diego County Department of Public Works Road Station with fueling stations operating from 1942 to 1998 and had several leaking USTs, which had impacted the soil and groundwater with gasoline. In addition, operations at former structures on the site had caused elevated lead concentrations in shallow soil from lead-based paint and asbestos in materials used for building construction. The UST case was closed in 2004 but left behind petroleum hydrocarbon impacts in both soil and groundwater. Working under the regulatory oversight of the County of San Diego Department of Environmental Health, MHC hired SCS Engineers to perform Phase I and II Environmental Site Assessments. SCS prepared and implemented a Soil Management Plan (SMP) to ensure proper management and removal of lead- and petroleum hydrocarbon-bearing soil to ensure the safety of future residents and the environment in the development area, including the adjacent Poway Creek.

Community Housing Works, North Park Seniors – The North Park Seniors Project is San Diego’s first LGBT senior housing project. The housing was built in an area historically developed as early as 1921 with previous commercial and residential land uses. Due to the historical land uses at the site, which included a former blacksmith and horse stables circa 1921, elevated concentrations of lead were present in the soil that exceeded residential screening levels. To protect human health for future residents and workers and save costs on soil disposal at a landfill, SCS proposed a unique plan. In collaboration with Community HousingWorks, the County of San Diego Department of Environmental Health, and the project design team, lead-bearing soil could be reused or safely buried beneath the project during grading activities. The plan also greatly reduced the amount of truck traffic and greenhouse gas emissions during site preparation.

RD Brown Company and EAH Housing – Imperial Seniors – A former gasoline service station in the City of Imperial is being redeveloped into an assisted senior living facility. The project has gasoline impacted soil, groundwater, and currently has an open unauthorized release case overseen by the Regional Water Quality Control Board. The Water Board allows the proposed development to move forward while the case is still open, provided that a vapor barrier is installed beneath the proposed building and groundwater remediation and monitoring continue until gas/benzene levels in groundwater meet acceptable levels. Construction is on schedule to start in 2022.

SCS Engineers Founder Tom Conrad Honored by SWANA with the Robert L. Lawrence Award

August 13, 2021

Leading environmental engineers, consultants, and contracting firm in the U.S.
Tom Conrad, Bob Stearns, and Curt Schmidt were the founders of SCS Engineers in 1970.


The International Awards Committee and Solid Waste Association of North America (SWANA) Board of Directors unanimously voted to honor Tom Conrad, the “C” in SCS, with the Robert L. Lawrence Distinguished Service Award at WASTECON 2021 in November. The Lawrence award is the highest accolade SWANA bestows on a member of the waste management industry, reserved for those making meaningful and lasting contributions.

“I’m honored and humbled to be selected for the Robert L. Lawrence Award. I thank you and am especially thankful for what SWANA and SCS are today,” stated Tom Conrad.

SWANA recognizes Conrad for over 60 years of significant influence on the waste management and environmental services industry. Conrad, a Founder, Executive Vice President, and Director Emeritus of SCS Engineers, dedicated his career to advancing solid waste management, most notably through the founding of SCS Engineers (Stearns, Conrad, and Schmidt Consulting Engineers) more than 51 years ago.

Tom Conrad worked on a wide range of environmental engineering projects touching almost every aspect of solid waste management throughout his career.  As an environmental engineering firm and consultant to the newly created US Environment Protection Agency (EPA), the founders recognized that responsible solid waste management was increasingly important for protecting the environment and the health and safety of the general public.

Leading SCS, he helped the EPA develop the first federal regulations for sanitary landfills, managing and capturing landfill gas, waste sorting protocols, sludge management, and land remediation.

Environmental services, including wastewater management, were always a significant part of SCS services and the waste industry. When new regulatory policies began expanding in the ’80s, SCS’s techniques, technology, and expertise helped a broad range of industries comply with environmental needs and continues today with the firm’s greenhouse gas, landfill technology, renewable energy, remediation, and sustainable materials management programs.

Conrad is also known for hiring and mentoring today’s SCS leaders, many of whom are SWANA leaders, by creating and fostering SCS’s culture encouraging employee participation in industry associations, community, and SCS’s mentorship and leadership programs.

SCS’s current executive leadership and SWANA members, Bob Gardner (Solid Waste), Jim Walsh (CEO), with Tom Conrad, and Mike McLaughlin (Environmental Services).


Before his retirement in 2016, Conrad held professional engineering licenses in 24 states. He was a member of SWANA, the American Society of Civil Engineers, the National Waste and Recycling Association, and the Society of American Military Engineers.

He maintains his “work hard – play hard” lifestyle. He is active at SCS, participating in Board of Director meetings and speaking at the Young Professionals Group events and celebrations. While no longer mountain climbing and biking cross-country, he has a vigorous walking, swimming, and biking schedule.


An icon at SCS Engineers and at home, Tom is not slowing down – he has more playtime now!


Congratulations, Tom!

2022 California Land Recycling Conference – CALRC , Carson, CA

May 26, 2021

The 2022 California Land Recycling Conference (CALRC), will be live again, June 21-23, 2022, in Carson, CA.

Communities recognize the need for equitable and resilient spaces more than ever before and amid the ongoing pandemic. The innovation and resolve that communities have found to move their land reuse projects forward to create vibrant cities, towns, and neighborhoods is truly inspiring.  The Bipartisan Infrastructure Law (BIL), Build Back Better, and other federal and state priorities, will provide the resources to create historic investment in brownfields, climate, and economic revitalization. And California is leading the charge.

Hosted by the Center for Creative Land Recycling (CCLR), U.S. EPA Region 9, and the CA Department of Toxic Substances Control’s (DTSC) Office of Brownfields, the California Land Recycling Conference is the premier event for professionals working on land reuse. Focusing on the most timely issues unique to California and resonating with the national big-picture, the Conference is an innovative space for learning and connecting.

Join us at the 9:30 am – 10:30 am Morning Plenary Session Beyond Brownfields: Landfills, Oil Wells and Superfund Sites, and more. Many communities have “beyond brownfield” sites, Superfund, landfills, oil fields, and hard-to-categorize sites that stymie a coordinated planning effort and can paralyze reuse for decades. This session featuring Mike McLaughlin will orient the audience on the roadblocks of redeveloping these sites and innovative workarounds with regulatory approaches and planning. Which brownfields resources and tools can be useful, and what can communities do to move these projects forward? And if barriers are insurmountable, what financial, policy and legislative fixes could help?

The Conference will bring together a multidisciplinary audience of redevelopment leaders to foster knowledge exchange, innovation, and support for land recycling in California communities. Come reuse, rebuild, and revitalize!
