Basically, it’s a study of the area’s elevation, in this case Unit 4’s area, to assess the property within that area and to show the proper drainage areas and directions of flow. It will show what/where it is needed to make the water flow properly. The full scope of the study is to develop a drainage area map for the major drainage paths within Unit 4. The drainage areas will be delineated such that peak flows in the 25-year and 100-year storm events will be calculated at various points along the path, such as road crossings.The result of the study is a map that shows flow patterns, drainage paths, contributing drainage areas and peak flows for the 25-year and 100-year storm event. As BCWCID #2 and County construct roads within Unit 4, this drainage study will be used to appropriately size required culverts and roadway ditches. Additionally, as lots are developed within Unit 4, homeowners and home builders can use the map to see drainage paths and avoid building homes in those paths.
