Abstract
Stormwater drain insert assemblies that reduce or remove environmental runoff during rain storms and the like are disclosed. The stormwater drain insert assemblies include a strainer basket and filter bag that capture sediment, hydrocarbons, heavy metals and other contaminants, but allow water to pass through. The stormwater drain insert assemblies include a top bib of flexible sheet material such as water-impermeable fabric surrounding and supporting the strainer basket. The strainer basket includes at least one raised overflow port extending upwardly from a top panel of the basket. The top bib has a frame that may be adjustable in size in order to fit into various sizes of catch basins, resting on the lip between the top grate and the catch basin.
