Target & Bed Bath and Beyond
Limestone mining and cement production began in 1909 and ceased in 2014. The primary environmental concern was cement kiln dust (CKD) containing heavy metals including hexavalent chromium. CKD was a by-product generated during the manufacturing process and was hauled from the cement kilns and deposited at several locations throughout the site. Although much of the previously deposited CKD was recovered and incorporated into the final cement product in the 1970s and 1980s, residual CKD remained at several locations on site.
Agua Mansa Commerce Park is a 206-acre property entitled for a Class A logistics park consisting of over 4.2 million square feet of commercial and logistics facilities. As an additional amenity to the community, Viridian left approximately 70-acres of quarry land as open space. The property is located within the Inland Empire West (IEW) industrial market, the largest and most active logistics markets in the world. The park is well-located, with excellent access to four major freeways bridging the Ports of Los Angeles and Long Beach to the western United States. Viridian secured both remedial and land-use entitlements. Demolition, remediation, and grading is near completion and vertical construction has commenced with project completion targeted in 2024.
Viridian navigated a complex entitlement process which included approval of an Environmental Impact Report in a political environment that opposed warehousing and had significant concerns over carbon emissions and protection of wildlife. Viridian worked openly with all stakeholders and developed unique solutions including a program to provide 250 residential neighbors with indoor air quality purifiers in addition to other extensive mitigation programs.
Viridian also processed a remedial response plan through the California Department of Toxic Substances Control (DTSC). The response plan focuses on capping of the remaining CKD through over 2M cubic yards of earth moving as well as other engineering controls. California Land Reuse and Revitalization Act (CLRRA) agreements were executed for each building site and the open space acreage, providing individual No Further Action letters (NFAs) as each of the building sites and open space are remediated.
