How to Find Storm Drains, Ponds or Other Stormwater Facilities

Storm drains, pipes or ponds can look different from neighborhood to neighborhood, and many features are underground.


Do a Visual Search

If it's raining, watch where the water flows from your neighborhood road into a catch basin (the visible part of a catch basin is the drain or grate above it).  Catch basins either lead directly to a river or stream, or to a pond or natural area where water can slowly seep into the ground.
