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.
Drawings are from the City of Toronto's, [https://www.toronto.ca/services-payments/building-construction/infrastructure-city-construction/construction-standards-permits/standards-for-designing-and-constructing-city-infrastructure/construction-specifications-drawings-for-green-infrastructure/?accordion=green-infrastructure-drawings Design Criteria for Green Infrastructure in the Right-of-Way] <ref>https://www.toronto.ca/services-payments/building-construction/infrastructure-city-construction/construction-standards-permits/standards-for-designing-and-constructing-city-infrastructure/construction-specifications-drawings-for-green-infrastructure/?accordion=green-infrastructure-drawings Design Criteria for Green Infrastructure in the Right-of-Way </ref> document.
