This represents the preliminary design for landscaping at Durbin. The plan created will emphasize water filtration and absorption as well as habitat creation and low maintenance. The stream bed and basin area will feature a rush and sedge mix that is evergreen and more rigid, to slow water flow and encourage filtration. The bio-filtration basin will be planted in bald cypress, selected because each tree absorbs hundreds of gallons of water per day, and they grow well both in standing water and are drought tolerant; also, their leaves do not create a lot of biomass. Tree plantings in other areas were selected to build habitat, including oaks and persimmons–which also can withstand standing water. White pines will be planted along the streambed and back property trail, as a screen and to provide food for wildlife. Rain garden areas that feature a wetland/wildflower mix will be planted around the injection wells and on the slopes near to housing areas. A tall prairie mix is recommended for areas away from the detention basin and houses; a benefit is the sound absorption capabilities of tall grasses. An area will be reserved for eventual planting of an orchard, after people have moved to the site and there is a maintenance plan. No shrubs are included due to having no added benefit and their high maintenance. The property will be seeded initially with oats to stabilize the soil and planting will occur in early spring. Invasives will be cleared and prohibited from being planted on the property in the future.
