===Parking lots===

Mid- and high-rise buildings have higher user occupancy densities than other sites and require significant parking area. To conserve site area, these parking lots are typically located underground. Mid- and high-rise buildings usually have flat roofs that drain internally to onsite storm sewer networks. They typically have common areas, but their size and function vary.

These areas represent the best opportunity for establishing LID practices on light industrial sites. Runoff from these catchment areas can be treated with the same suite of LID options for commercial lands.

Institutional sites present many opportunities for landscaped area retrofits.  Often found along pedestrian pathways and adjacent to buildings, landscaped areas are ideal for establishing highly visible LID practices like bioretention areas or bioswales. Gardens and parking islands in close proximity to buildings can be converted to bioretention areas and/or irrigated via a rainwater harvesting system.

To reduce site maintenance costs on large properties, site owners should consider alternative landscaping to a high-maintenance lawn. No-mow or naturalized areas require minimal maintenance compared to mown grass areas and can greatly reduce site runoff by encouraging interception by tree canopies and evapotranspiration by green vegetation. Naturalized areas with cleanly mowed edges and colourful plant species can still give the impression of an orderly and attractive landscape.
