Parks range from simple parcels of municipal property to complex outdoor recreational facilities that include parking, sidewalks, trails, sports fields, field houses, operations facilities, and washrooms. Each distinct area of your site can be a source for runoff (referred to as a ‘source area’). These areas should be targeted when introducing LID in your park.
