Drawings

Whilst we consider preparing our own set of STEP LID drawings, we are providing a quick reference list to DWG files from others (including proprietary systems).

If you want help in finding example details for an LID design, please email STEP or use the comment box below.

You know that typical drawings are no substitute for engineered design!

Proprietary

In our effort to make this guide as functional as possible, we have decided to include proprietary systems and links to manufacturers websites.
Inclusion of such links does not constitute endorsement by the Sustainable Technologies Evaluation Program.
Lists are ordered alphabetically; link updates are welcomed using the form below.

Sustainable Technologies Evaluation Program

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.
