'''[[Enhanced grass swales]]''' are a lower maintenance alternative, but generally have lower stormwater management potential. The enhancement over a basic grass swale is in the addition of [[check dams]] to slow surface water flow and create small temporary pools of water which can infiltrate the underlying soil.<br>

'''Grass swales''' are a relatively common landscape feature already and a great opportunity for retrofit, to reduce flow and improve water quality by encouraging settling and infiltration behind a series of check dams.

'''[[Retention swales]]''' can be imagined as linear, sloped [[dry ponds]]. They make a relatively little contribution to water volume and quality control than many other BMPs, but they may feature as part of a site-wide treatment train approach.
