Who it's for
U.S. homeowners with a downspout, a suitable yard area, and recurring runoff or drainage problems. No landscaping experience is needed, but the work involves digging and hauling soil by hand over one or two days.
About this playbook
This guide walks you from a single overflowing downspout to a finished rain garden that absorbs roof runoff and, where your town offers one, a rebate that pays part of the cost. You will measure your roof and soil, size the garden with a simple calculation, find the stormwater incentive that actually applies to your address, and build the garden in a weekend of steady work. Along the way you call 811 for utility locates, dry-run the water path before any digging, and test that the finished basin drains within 48 hours. The final steps submit the claim paperwork and leave you a seasonal maintenance calendar and a complete installation record. It does not cover ponds, French drains, or engineered infiltration systems, and it assumes no single national rebate exists — the incentive step is about discovering what your own locality offers.

Details
What you need first
You have a downspout that discharges onto a lawn or planting area at least 10 ft from the house foundation, access to a garden hose, basic tools (shovel, rake, level, wheelbarrow), and the physical ability to dig a basin of roughly 3–10 ft by 6–15 ft. Your local rules and any rebate program must permit the work — the guide shows you how to check before you dig.
