This Microsoft Excel-based calculator is designed to help landscape and construction companies estimate the cost of using environmentally beneficial compost filter berms or compost filter socks for erosion control, rather than conventional silt fences. Inputs are: linear feet of erosion control needed, estimated duration of project, and whether or not compost will be removed after the project. The Cost Calculator demonstrates that environmentally preferable erosion control methods are very cost competitive for all project sizes and durations, and that they offer significant savings for projects that run for more than a few months.
