Rain Garden Advisor

A flood is made from millions of drops adding up

Flood mitigation is built one garden at a time.

Give the rain somewhere to go.

A rain garden is a shallow, planted dip in your yard, set where runoff already flows. It catches the water sheeting off your roof and driveway — your share of what would otherwise rush to the storm drain.

  • Soak, don't flood. It sinks in slowly instead of overwhelming the sewer.
  • Filter the bad stuff. Soil and deep roots trap oil, fertilizer, and grit before they reach our creeks and rivers.
  • Habitat, too. Flowering plants bring in pollinators.

Small effort, real math: one modest garden can divert thousands of gallons a year. Multiply that by a block.

This rain garden was planted in September 2025.

How it works

  1. Enter your address — anywhere in the contiguous U.S. — and we pull your local rainfall and growing conditions.
  2. Answer a few questions — soil, sun, space, water source.
  3. Get your plan — size, depth, and plants for your rain garden.

If you've got a patch of yard, a downspout or two, and a free weekend in you — this is for you. No landscaping experience required. This is a beginner-friendly, dig-it-yourself way to pitch in on storm water management.
