Featured Project
Redevelopment Project & Rain Garden
This project site was located in an area susceptible to sinkhole formation, within a regulated Water Resource Protection Area (WRPA), and near key public drinking water supply wells. Our water resource team worked with the clients' designer to develop a stormwater management program that utilizes diffuse recharge stormwater management practices to mitigate the potential for the development of sinkholes while protecting critical groundwater recharge volume and quality. On-site stormwater management practices that were implemented include a large rain garden, and harvesting and storage of rooftop runoff in underground tanks for irrigation purposes. This was selected as a Storm Water Solutions Magazine "Top 10" 2008 Project...see press release.
