Background
Lennar Homes, LLC contacted SCS Engineers to assess and support the remediation of a 100+ acre former golf course for residential redevelopment.
Environmental Challenge
Due to the historical application of legally applied herbicides and pesticides used for golf course maintenance, remnants of arsenic and organochlorine pesticides require soil management efforts during site redevelopment and groundwater monitoring is required for installation of stormwater drainage features and overall environmental site closure.
Earthwork and home construction had commenced under a previous consultant, prior to SCS’s role. Permits were being held up by Miami-Dade County, due to environmental hurdles that were not cleared. Lennar needed to meet a deadline to close sales on homes being constructed to meet their financial goals in 2019.
Outcome and Benefits
Within four months, SCS had worked with Lennar on the strategy to achieve a No Further Actions with Conditions environmental site closure and implementation of the Restrictive Covenant with Miami-Dade County. SCS began work in March 2019 and the Restrictive Covenant was recorded in July 2019 for the first phase of the redevelopment.
As a result, Lennar was able to close on homes they had sold and the county lifted the holds on the Certificate of Use for the homes, taking the first step to achieving their financial goals. The remainder of the redevelopment is on a similar track, following the closure strategy.
Planning site work, as well as reporting to the regulatory agency, and using GIS tools (ArcGIS Collector and ArcGIS Online) were all instrumental in achieving the aggressive timeline. Successful collection and management of a large amount of data collection and analysis was completed quickly, along with soil blending pilot testing.
