WebThe cost of bioretention soil mix is varies depending on a few factors. The primary factor determining cost of the engineered soil media is the mix design, including the components of available bulk sand, soil, compost, and other materials. Sand cost ranges from $8 to $30 per ton on average. The lower cost sand from sources in Georgia is often ...

WebAdditionally, bioinfiltration swales must accommodate both the water quality and flow control design storm event. If they do not, overflow structures (e.g., drywells) are required to handle the flow control design storm. This further indicates that the City’s bioinfiltration and bioretention facilities do not function as pre-treatment to WebGravel infiltration trenches. Dry wells. Conveying water.
