Stormwater Bioswales and Rain Gardens

Planted stormwater features that slow, clean and absorb runoff in parking lot islands, buffers and low spots, while looking like a landscape.

Stormwater rules push commercial and community properties to manage runoff on site, and the old answer, a concrete pipe and a pond, is not always the best one. Bioswales and rain gardens are planted depressions designed to capture runoff, let it soak into the ground and filter pollutants through soil and roots. They reduce flooding, protect streams and ponds and can count toward stormwater requirements, all while adding greenery to places that would otherwise be bare turf or pavement. In Nashville, where heavy downpours are routine, these features are increasingly used on offices, campuses and communities.

We install and maintain bioswales and rain gardens as functional landscape features. Design starts with the drainage area and soil percolation, then sets depth, bottom width, side slopes and inlet and overflow details. Soil mixes are specified for infiltration, and plants are selected for their ability to handle wet and dry cycles, with native sedges, rushes, grasses and perennials. Mulch or stone protects soil, and we plant densely to shade out weeds. Because plants do the work, maintenance matters in the first years, with watering, weeding and inlet cleaning, and we provide plans and service to keep the feature performing.

Planted depressions slow water and filter it through soil and roots.

Designed for infiltration

Soil mixes, depths and overflows are set for how fast the site drains.

Plants that handle extremes

Native species survive both wet and dry cycles with little inputs.

Care plan built in

First-years care keeps the feature healthy and the inlets clear.

    Proposal and options

    You receive an itemized written proposal with areas, tasks, frequencies, seasonal services and options, ready for a board or owner to review.

  4. 04

    Onboarding

    We document starting conditions with photos, map the property, set the schedule and contacts and complete any catch-up work in the first month.

  5. 05

    Service and projects

    Crews follow the schedule, projects are phased around your operations and visits are logged so you can see what was done.

  6. 06

    Review and plan ahead

    We review results with you each quarter, adjust the scope as needed and plan seasonal work and reserve projects for the year ahead.

Questions

Bioswales and Rain Gardens FAQ

Will a rain garden hold standing water?

It is designed to drain within a day or two, so it should not stay wet or breed mosquitoes.

Do bioswales count for stormwater credit?

They may, depending on local rules and design, and the project engineer confirms that.

What plants work best?

Native sedges, rushes, grasses and perennials that tolerate wet and dry periods.

Do they need maintenance?

Yes. Weeding and cleaning inlets matter most in the first few years.

Can they fit in a parking lot island?

Yes. Curb cuts let water in, and the island is shaped to hold and absorb it.
