Smaller rain gardens can be dug by hand with a shovel. 2 0 obj<> Vegetated bioswales: The swales can be planted with ornamental grasses, shrubs, perennials, or a combination of these. Your goal should be to enhance and utilize existing natural drainage swales whenever possible, You can enhance existing swales with native plant species (thicker, heavier grasses, as well as deep-rooted native plants, tend to be better when filtering out contaminants), You may need to add subgrade drains and amended soils to facilitate infiltration, Your costs may greatly vary when designing or maintaining a bioswale depending on size, plant material, and site considerations (fortunately, bioswales are generally less expensive when used in place of underground piping), Your soil infiltration rates should be greater than one-half inch per hour, You should strive for a parabolic or trapezoidal shape with side slopes being no steeper than 3:1, You should avoid soil compaction during installation, Your swales should be sized to convey at least a 10-year storm (or about 4.3 inches in 24 hours). All six lift stations are original to the development of their respective neighborhoods and while they have received appropriate maintenance, all are at the end of life.
