Abstract
An adjustable curb guard filter apparatus for filtering liquid flowing into a curbside drain and method for deploying the same. In accordance with one embodiment, the adjustable curb guard filter apparatus includes a filter sheet disposed between an upper and a lower of a pair of support bar members. The curb guard filter apparatus is deployed onto the curbside drain such that the ends of each of the support bar members exert an outwardly directed pressure against the inner lateral surfaces of the curbside drain enabling the filter sheet to form a substantially complete seal thereon. In a preferred embodiment, the lower end of the filter sheet is wrapped in a scroll-like manner around the lower support bar member such that when installed onto the curbside drain, the wrapped lower support bar member simultaneously provides dam and liquid filtration functionality along the bottom edge of the curbside drain.
