Jan 9, 2023 · A rain garden is a collection of shrubs, perennials, grasses and flowers which are generally planted in a small depression. They are specially designed to soak in extra rainwater runoff from hard surfaces such as roofs, patios or driveways.

A bioswale is a linear, open, vegetated channel that directs rainwater runoff from its source to a rain garden, from a rain garden to the traditional rainwater system (culvert, etc.), directs water flow through a property, or simply catches water as it flows off edges of pavement.

Jun 21, 2021 · Generally, rain gardens are sized as 10 percent of the impervious surface area draining to the garden. The size of a rain garden refers to the volume of water it can hold before the water overflows at the exit point. This volume is described in terms of ponding depth and square feet of surface area (depth × width × length).

It's easiest to install a rain garden in an area of your yard that water already flows to, usually a depression in the ground or a spot at the bottom of a slope. you can usually identify a suitable area by examining your yard during a rain storm to see how water flows off it.

If the site has a moderate slope, consider building a linear rain garden or bioswale along the contour of the hillside. The use of erosion control fabric may be needed on a moderate slope to prevent erosion while plants are becoming established.

Rain gardens are a sustainable landscape solution for managing stormwater run-off, and they range from simple ornamental gardens designed to tolerate water in low-lying swales, to bioswales that naturally filter water, and more robust green infrastructure that removes particulates and oils through water quality units.

Rain Gardens are shallow depressions (bowl‐shaped or linear) that treat stormwater with soil and plants though ponding (aka bioretention). To protect water quality and create a low maintenance facility, a rain garden should be built in the right place.

Rain gardens are specially designed and planted depressions in the ground that collect, filter, and treat stormwater. These slightly sunken gardens allow collected water to be taken up by plants or slowly infiltrated (i.e., filtered into the ground), reducing the amount of water running off site.

Learn what it takes to make your own rain garden in a low-impact design landscape. A rain garden is a sunken garden bed that collects and treats stormwater runoff from rooftops, driveways, sidewalks, parking lots, streets, and lawns.

Apr 7, 2023 · Installing rain gardens in our communities can be essential for the health of our waterways. As our green spaces become overdeveloped, rain gardens will become vital. They play a huge role in guarding our waterways against nonpoint source pollutants (NPS) contained in runoff water. What Are Nonpoint Source Pollutants?
