Bioswale in a Corporate Setting

- Adapted from illustration by Doug Adamson.

This illustration depicts the following features of a bioswale:

Native Landscaping.
Deep-rooted native shrubs, forbs, and grasses build soil structure and allow water to infiltrate into the ground more easily than nonnatives. Native plants are low maintenance, adapted to Montana climate and rainfall patterns, and resist local pests and disease.

Soil Amending.
Along with native plantings, soils amended with compost and sand may be needed to facilitate infiltration. A rock trench can be installed down the center of the swale.

Infiltration.
Water infiltrated through bioswales helps recharge groundwater, which supplies rivers and streams with a slow, purified seep rather than surges of polluted surface runoff from roofs and other impervious areas.

Strong Deep Roots.
Native plants have a tremendous root architecture that builds soil quality and increases organic matter content. High organic matter content helps soil hold water like a sponge making it available for nourishing plants.
