Project Description

The site of the new bank 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. Duffield Associates’ water resource team worked with TD Bank’s designer to develop a stormwater management program that utilizes diffuse recharge stormwater management practices to mitigate the potential for the development of sinkholes at the site 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.
