  • Rain Gardens

A rain garden is a planted depression or a hole that allows rainwater runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas, the opportunity to be absorbed. This reduces rain runoff by allowing stormwater to soak into the ground (as opposed to flowing into storm drains and surface waters which causes erosion, water pollution, flooding, and diminished groundwater). Rain Gardens are increasingly being required by municipalities as a more sustainable way of treating stormwater. CSG has extensive experience designing and installing rain gardens.

  • Bio-swales

Bioswales are landscape elements designed to remove silt and pollution from surface runoff water. They consist of a swaled drainage course with gently sloped sides (less than six percent) and filled with vegetation, compost and/or riprap. CSG can design and install bioswales to fit certain pollution issues on various sites.
