If your site required a Construction General Permit, you will be responsible for operating and maintaining any post-construction best management practices (BMPs) that were included in the site plans. Examples of post-construction BMPs may include:
- Wet detention ponds
- Dry retention ponds
- Bio-swales
- Bio-retention (rain gardens)
- Constructed wetlands
- Infiltration trenches
- Infiltration basins
- Sand filters
- Vegetated filter strips
- Subsurface detention
- Green roofs
- Conservation easements
- Riparian buffer zones
- Pervious concrete
- Porous pavement
- Porous pavers
The Stormwater Management Department conducts post-construction inspections of these practices, to verify that they are being maintained properly. Post-Construction BMPs and their maintenance are required by local, state, and federal law as part of the Clean Water Act. Examples of maintenance issues may include:
- Inlet or outfall blockage
- Trash/debris removal
- Erosion
- Sediment build-up
- Invasive plant species removal
- Missing or dying vegetation
- Tree/shrub replacement
This 8-minute video describes the steps required to maintain a residential stormwater management pond. The primary target audience is home or property owners’ associations, but residents living in a community with a stormwater pond can also benefit from this information. Topics covered include an explanation of what a stormwater pond is, why it is necessary, why some ponds fail, what to look for when inspecting the pond, expert tips on maintaining the pond, and how this on-going, needed maintenance is typically paid for.
