Mark has been busy out at LRB Cantina this week, installing a sub-drain and bioretention media in the parking lot.
Bioretention areas are used to help treat the first “flush” of rainwater from paved areas. The intent is to reduce suspended solids and petroleum from leaving the site. The use of mixed compost and sand provide a filter bed plants will grow in that help process the petroleum and provide visual interest to an environmentally important feature. Our Bioretention area was not required as part of our project, since our site and the adjacent graphite plant’s storm water has discharged to the Catawba River for decades. We are also utilizing water quality inserts in the storm inlets in the parking lot to help filter the water we could not accommodate in the Bioretention feature.
Stay tuned for more information on our sustainability efforts at LRB Cantina!
