A Planting Guide for Enhancing LID Measures that provides land managers and professional practitioners with an understanding of the guiding principles of LID planting design, implementation and management.
Low impact development (LID) is intended to treat stormwater runoff at the source. LID practices are predominately located on private property or within the right-of-way and will often be maintained by the property owner. LID is also different because many of the practices have an integral vegetated component, which supports the treatment, evapotranspiration and infiltration functions. Thus, the plant selection and design are essential both for function and for the public perception and acceptance of LID practices in the landscape.
This document – the Planting Guide for Enhancing LID Measures – has been developed by Credit Valley Conservation (CVC) in consultation with the Toronto and Region Conservation Authority (TRCA) and member municipalities. It is intended to be an appendix to the Low Impact Development Stormwater Management Planning and Design Guide (LID Guide), providing support related to the plant selection and design of LID landscape. The LID Landscape Design Guide complements the LID Guide by providing land managers and professional practitioners with an understanding of the guiding principles of LID planting design, implementation and management. While useful for the facilities and locations described, these guidelines may not be suitable for natural stormwater management approaches (i.e. natural channel design, floodplain storage or wetland applications) or in locations outside of CVC and TRCA jurisdictions.
• The practitioner must respect local bylaws and standards, agency requirements and applicable legislation.
• Plant species recommendations are targeted for the greatest performance in the CVC and TRCA jurisdictions.
