 ====== Stone Crib ======
-A stone crib is a designed basin that collects the first ½ inch of stormwater from a site and reduces its velocity by passing it through the basin.  This action promotes sedimentation and reduces the temperature of runoff by utilizing the heat exchange capacity of the stone.  As stormwater enters the stone crib, it is passed through a layer of pervious pavement block and pea gravel, which filter out sediment and other particles.  It then mixes with the stone and any stored water in the crib, exchanging heat with the cooler F water.  Trash and other large debris are collected upstream of the device by a [[gabion]].  The cooled water is released slowly to a stable outlet.

 Stone cribs are widely applicable, particularly in temperature sensitive watersheds.  As these devices are only designed to provide treatment for the first ½ inch of runoff, large storm events may overwhelm the capacity of the practice.  As a result, they are best used in conjunction with other management practices.
