Yard Flooding From Downspouts in Orlando: Causes and Fixes That Work

Understand the cause first:

• Short discharge. Water lands within a foot or two of the wall and pools.
• Flat grading. Water has nowhere to run, so it sits.
• Inward slope. The ground slopes toward the house.
• Clogged downspouts. Water backs up and overflows at the gutter, not the outlet.
• High water table. In wet season, the ground can be near saturation.
• Undersized outlets on large roofs that send more water than the yard can take

Try these in order:

• Clear downspouts and gutters. Sometimes the flooding is an overflow problem.
• Add an extension or splash block that carries water several feet away. See downspout extensions.
• Redirect the outlet to a side of the yard that slopes away
• Regrade the soil so it falls away from the foundation
• Install a pop-up emitter on a buried line. See pop-up drain emitters.
• Install a buried drain to carry water to a discharge point. See underground downspout drainage.

Choose a destination that can take it:

Do not send water onto a neighbor's lot. Some drainage patterns in HOA communities are regulated, and retention areas have rules, so check before altering them. Do not connect roof downspouts to a sanitary sewer, which is prohibited in many places.

• A lawn or garden bed that slopes away
• A swale that leads to the street or a retention area
• A dry well in suitable soil
• A rain barrel for garden use, with overflow planned

Call 811 before digging so buried utilities are marked. A professional installer handles this, and it is a good reason to hire one for buried lines.

Extensions typically run $75 to $450 across a house. Buried drains and emitters run $500 to $2,500. See downspout replacement cost in Florida for the price comparison.

If water pools even in dry weather, or you see wet spots far from downspouts, the source may be irrigation, a plumbing leak, or the water table. If the house shows cracks or water entering, call a professional. The University of Florida IFAS Extension and the U.S. EPA WaterSense program have information on managing water in Florida yards.

The best time to diagnose yard flooding is during or just after a storm. Walk the yard with a rain jacket and look for:

Take photos and mark spots with flags. That gives an installer real information.

• Where each downspout empties, and whether water stands there
• Low spots that hold water for hours
• Places where water runs toward the house
• Drains, swales, or ditches that overflow or are blocked
• Wet spots that appear far from any downspout, which may point to another source

Surface solutions are cheaper and easier to adjust, and they work when the yard slopes away and stays clear of foot traffic. Buried lines cost more and keep the lawn clean, and they suit flat or tight lots and areas where extensions would be in the way. Ask an installer to explain why they recommend one over the other for your yard.

Extensions typically run $75 to $450 across a house. Pop-up emitters run $200 to $750 each. Buried drains run $500 to $2,500. Sometimes the cheapest answer is the redirect of a single downspout. See pop-up drain emitters and downspout placement for Orlando yards.
