Locations where stormwater flows when it drains from your roof areas

Check all of the locations where stormwater flows when it drains from your roof areas. Check all of the conditions that apply at your property—your roof runoff may be going to more than one place.

Off of my property… to street, drainage ditch, sewer, stream or other location

Check this if some or any of your downspouts have roof runoff that leaves your property. This includes downspouts that lead to your driveway and then off of your property, as well as drains that go directly to a street, sewer, drainage ditch, stream, river or other area off of your property.

From the roof direct to drywells, French drains or soakage trenches on my property

From the roof direct to a swale, lawn, garden or landscaped area to infiltrate on my property

From the roof direct to cisterns or rain barrels that allow for overflow onto my property

From the roof to a holding facility, stormwater planter or pond that slowly releases stormwater off my property
