 Your Stormwater Facility

Stormwater facilities can be an attractive and functional part of your property. Properties that have stormwater facilities will generally have either a wet pond or a dry pond. Both of these stormwater facilities capture and contain stormwater runoff from rain events. Wet ponds generally have water in them year round and serve to treat the stormwater by allowing dirt to settle to the bottom of the pond before discharging the water into a nearby waterway. Dry ponds on the other hand only have water during rain events and work to slowly release water into streams after an event. These ponds can often serve as grassy play areas or open spaces for wildlife during drier seasons.

 Who is Responsible for Maintaining Stormwater Facilities?

It is important for all stormwater facilities to be maintained. Regular maintenance ensures your facility is functioning properly and can help to save you money in the long run. Commercial property owners, homeowners, or homeowner's associations are responsible for providing regular maintenance of privately owned ponds, storm drains, pipes, and other drainage facilities that serve the property or subdivision. Local governments maintain stormwater facilities located in public right-of-ways. 

Does the City Offer Any Guidance on Maintenance Practices?
