The Wisconsin Department of Natural Resources (WDNR) updated Technical Standard 1060 Storm Drain Inlet Protection for Construction Sites is now available on the WDNR’s storm water construction technical standards webpage. The standard was revised to incorporate the use of rigid frame type inlet protection devices and to aid in device selection. This practice is intended to minimize sediment from entering storm drainage systems in areas where the contributing drainage area is temporarily disturbed or receives traffic from temporarily disturbed areas nearby.
This technical standard revisions included input from public review and was updated through the Standards Oversight Council (SOC) Modified Process.
