The table above shows the generalized capital costs for construction (both new and retrofit) and maintenance of the listed structural BMP's. The capital cost of conventional BMP installation varies widely depending on the site conditions. The primary factor is whether the BMP will be implemented as part of a new construction or is a retrofit project. The table provides costs on a dollar-per-acre basis, assuming a 1-inch capture rate from the contributing watershed. Construction cost data are site-specific and the values should be considered valid for planning and comparison purposes only.
