Please find below two sets of profile and plan view drawings of a bioswale and enhanced swale installation. Both installations are located in between the front of a private homeowners' property and the roadway, known as a easement/frontage/easement. The major difference between the two installations is the use of an underdrain for the bioswale, drainage layers, specialized filter media laid underneath the geotextile underlain rip-rap so that it provides partial infiltration. Whereas, the enhanced swale provides full infiltration, through a fully vegetated surface, allowing water to travel down slowly to the undisturbed soil substrate below. | Please find below two sets of profile and plan view drawings of a bioswale and enhanced swale installation.
