=== LID Opportunities and Land Use Types ===
If working in a retrofit scenarios, land use type in particular will have various constraints to work with. Road ROWs, residential, industrial, commercial, institutional, and park lands all have unique site constraints and corresponding LID opportunities. To help understand these unique land type constraint and potential LID options, see

[http://www.sustainabletechnologies.ca/wp/home/urban-runoff-green-infrastructure/low-impact-development/low-impact-development-stormwater-practice-inspection-and-maintenance-guide/ LID Inspection and Maintenance Guide] is intended to assist municipalities and industrial/commercial/institutional (ICI) property managers with developing their capacity to integrate LID BMPs into their stormwater infrastructure programs. Part 1 of the document provides guidance on designing an effective LID BMP inspection and maintenance program, based on experiences and advice from leading jurisdictions in the United States, adapted to an Ontario context. Part 2 of the document establishes standard cold climate protocols for inspection, testing and maintenance of seven types of structural LID BMPs.
