Roof Runoff Mapping
We trace gutter lines, downspout outlets, and low spots. This gives you a map of the water path.
We route roof water into rain gardens instead of weak soil spots. The design suits hot summers, storms, and older Memphis homes.
Rain Garden Gutter and Downspout Retrofits are drainage upgrades that route roof water into planted soil beds.
A 1-inch rainfall on a 1,000-square-foot roof produces approximately 623 gallons of runoff, a sizing input for routing gutter downspouts into a rain-garden retrofit.

Rain gardens should be located at least 10 feet from a house foundation, as reported by Virginia Cooperative Extension (2015), to provide a siting safeguard when redirecting gutter downspouts to a landscape infiltration area.

Figures published by NC State Extension (2022) indicate that a rain garden should drain its captured runoff within 12 to 48 hours, a performance criterion for a properly functioning downspout-to-rain-garden retrofit.

Rain Garden Gutter and Downspout Retrofits move roof water away from weak spots. Memphis has hot summers, mild winters, and frequent thunderstorms. These changes help limit washout near foundations, paths, and flower beds. Midtown and Cooper-Young have older brick and wood-frame homes with tight yards. Downtown condominiums often need shared access and careful overflow planning. Suburban ranch homes may have more room for a planted bed. A common shortcut is to add a longer pipe without testing the outlet. We trace the flow first, then set the bed, inlet, mulch, and overflow point. Local permit checks may apply when work changes drainage near a property line.

After another storm, a Memphis, TN homeowner sees the same soil trench beside the wall. A short pipe moved the outlet, but it did not slow the flow.
