Closed Landfill Brownfield Redevelopment in Cudahy, Wisconsin
SCS Engineers (SCS) served as the environmental engineer for the Cudahy Gateway Real Estate redevelopment project. The former 9-acre solid waste landfill was for prepared for redevelopment through a dynamic compaction process involving two cranes dropping 10-ton weights to compact the soil in order to create a solid foundation for construction.
The property was then capped and prepped for redevelopment, including incorporating provisions for special storm water and methane venting and monitoring. Through this strategy, a once undevelopable landfill is now home to five buildings and is operating as a successful commercial business.
SCS employed the following services to ensure redevelopment occurred:
Design of storm water management plan; approved by the City of Cudahy and the Milwaukee Metropolitan Sewerage District.
Design of landfill gas barrier system, site development grading plan, site layout, pavement, and utilities.
Oversight of dynamic compaction to stabilize the ground for building construction.
Exemptions for key project components from the WDNR, including an exemption allowing SCS to build on the landfill and to use crushed concrete fill with low-level contamination on site to raise site grades in order to save on landfill disposal costs.
Easement negotiations with adjacent property owners for site utility connections.
