==Inspection and Maintenance==
Maintenance requirements for [[enhanced swales|enhanced grass swales]], and swales is similar to vegetated filter strips and typically involve a low level of activity after [[vegetation]] becomes established. [[Grass]] channel maintenance procedures are already in place at many municipal public works and transportation departments. These procedures should be compared to the recommendations provided on the [[Inspection and Maintenance: Enhanced Swales]] page to assure that the infiltration and water quality
benefits of enhanced grass swales are preserved.
Routine roadside ditch maintenance practices such as scraping and re-grading should be avoided at swale locations. Vehicles should not be parked or driven on grass swales. For routine mowing, the lightest possible mowing equipment should be used to prevent soil compaction.
For swales located on private property, the property owner, resident or manager is responsible for maintenance as outlined in a legally binding maintenance agreement. Roadside
swales in residential areas generally receive routine maintenance from homeowners who should be advised regarding recommended maintenance activities and ensure they do not build anything within or on the channel of the swale which could result in flooding or pooling on theirs or their neighbours' properties.
