Abstract: An apparatus for construction site erosion control for temporarily enclosing the curb inlet of a storm drainage system during construction of a road system in commercial and residential developments is adapted to be placed adjacent a curb inlet of a storm drain in order to enable storm water runoff to drain into the inlet while preventing silt and debris from being carried into and collected therein. The apparatus includes a grate constructed to seat upon an open end of a storm drain inlet, means for filtering debris from storm water runoff passing through the means and through the grate, into the storm drain inlet; and means for securing the grate to a storm drain protection bar.
