Raingardens look like typical gardens. However, their [[infiltration]] and [[bioretention]] functions are much greater than normal gardens. By landscaping areas to include a surface depression of approximately 150 mm, rain gardens allow runoff from residential properties to collect and to easily absorb into the ground. Within the rain garden, special types of soil, '[[filter media]]' or [[soil amendments]] increase the amount of water absorbed by the garden and infiltrated into native soils.
Location is very important to a functioning rain garden. When looking at potential locations, look for low areas where runoff can be easily be directed into the garden. Rain gardens are a great option for residential LID retrofits because homeowners can customize the garden to suit their desired styles. They can be planted with a variety of vegetation including [[Shrubs: List| shrubs]], [[Graminoids: List|grasses]] and [[Perennials: List|flowers]].
A well-designed rain garden can be maintained with minimal care, which is a great marketing point for persuading homeowners. In the first two years, the plants will need watering to ensure they become established. After this establishment period, the garden should only need simple maintenance, e.g. weeding.
