| Abstract: |
Best management practices (BMPs) are used to mitigate the impacts of development on the environment. A life cycle analysis (LCA) is a systematic method for identifying and quantifying the effects of various factors upon BMP field efficiencies. Two life-cycle factors for 2 different LCAs are studied. The first factor is the installation probability for designed and approved silt fences during the construction phase of individual lots in a residential subdivision. Ownership change of the lots during construction is also investigated to determine its effects on this factor. The second factor is the probability a permanent residential detention facility will receive uncontrolled sediment loads from individual lots during the construction phase. The study focused on 14 residential subdivisions from which 184 construction phase lots were field visited and the files of 330 lots were researched on land records. Designed and approved silt fencing was only installed at 27% of the field visited lots. Of the 330 records researched, 76% of the lots underwent a construction phase ownership change. In the 14 subdivisions, 47.4% of the permanent detention facilities were receiving uncontrolled sediment loads from 1 or more individual lots. Typical damages to the facilities included partial or full clogging of basin inlet and outlet structures, loss of reservoir volume, side-wall erosion, and vegetation damage. |
