4. Trees can be installed outside of swales to further enhance the effect of reducing stormwater without having an adverse effect on long-term root growth.
5. Hold an educational session before, dur- ing, and after the installation to explain the project to local residents.

7. Long-term maintenance contracts for the facilities should be in place prior to installation.
