1. A storm drain sediment filter comprising:

  • an adjustable frame comprising four L-shaped rigid members, wherein each L-shaped rigid member has a first end and a second end, wherein a first retaining member is non-slidably fastened to the first end of each L-shaped rigid member and at least a second retaining member is non-slidably fastened to each L-shaped rigid member in a spaced apart relationship relative to the first retaining member such that the spacing between the first retaining member and the second retaining member is between about 0.5″ and

    about 5″

    , and wherein the four L-shaped members are arranged to form a rectangular shape such that a portion of each L-shaped rigid member inward of the second end is slidably received by first and second retaining members non-slidably fastened to an adjacent L-shaped rigid member; and

    a filter portion comprising a collar portion that includes a seam that forms a loop that encapsulates the adjustable frame such that the filter portion spans the adjustable frame;

    wherein the filter portion further comprises a filter bag that is suspending from an opening provided in the collar portion;

    wherein no structure is formed on or provided on the L-shaped rigid members which would prohibit the portion of each L-shaped rigid member inward of the second end that is slidably received by first and second retaining members non-slidably fastened to the adjacent L-shaped rigid member and the second end from being withdrawn from the first and second retaining members non-slidably fastened to the adjacent L-shaped rigid member by expanding the adjustable frame, andwherein the loop that encapsulates the adjustable frame limits a maximum expanded dimension of the adjustable frame such that no second end of any L-shaped rigid member can be withdrawn from the first and second retaining members non-slidably fastened to the adjacent L-shaped rigid member.
