Roof water runoff solutions.

Last week i talked a bit about how a green roof is one way to help manage stormwater runoff. To mitigate flooding one could add drainage on the sides of the pavement. If you have heavy runoff from roof downspouts and neighboring properties redirecting or capturing runoff can provide better control. However when water is flowing it can be routed to the well by a swale or roof downspout.

Here s a look at some options. A more effective solution is to ditch the asphalt or concrete pad altogether. Sometimes a combination of solutions is the best plan. A 1 000 square foot roof can produce more than 600 gallons 2 271 2 l of runoff for every 1 of rain that falls on it.

A fast draining soil mix encourages water to sink in and promotes lush plant growth. A simple rain catchment system can provide water for outdoor use resulting in. A shallow trough is lined with stones or rocks offering excess water a place to flow and runoff. Runoff may flow into a rain garden from a swale or pipe or may simply run in from a sloping yard.

The following approaches to redirect and capture runoff can be used to control heavy runoff causing prolonged wet areas or yard erosion. Where a swale is mostly a travel route for water a rain garden is a destination. Use the water that drains off your roof. How to calculate roof runoff.

Another simple and straightforward way is to make sure that the landscape of your garden is permeable including your hardscaping paths decks and driveways. These techniques will minimize the amount of water that accumulates or that causes erosion in the problem area. Gravel spaced paving and even grass can be used in making a driveway an asset in the rain. Use a shallow gravel filled trench to catch and slow runoff especially at the base of a slope or alongside a driveway or patio.

Next to roofs driveways are the other biggest contributor to storm water runoff. Dry wells are particularly helpful in a spot where downspouts are flooding a large paved area or when you. Use this water to irrigate garden plants. This is a subtle and creative solution for backyard drainage issues that offers a bonus.
