The concept plan below shows a design plan for managing stormwater at an apartment complex.

• There are two rain gardens.

• The arrows show the direction runoff flows in.

• The pink areas are impermeable surfaces: water flows from these areas into the rain gardens.

• Note the pollution reduction calculations for the rain gardens.

• The photos show ideas for the project.

The site design below, a small business property, shows how a finished project could look. New features are highlighted.
