restoration of the stream would require permitting. The catchment basin <br />should be placed outside of wetlands, to the maximum extent practicable, and <br />any wetlands that cannot be avoided should be excavated in such a way that <br />the top 12-16 inches of topsoil will be stockpiled seperately from the <br />sub-soil. During restoration the sub-soil should be placed first with the <br />topsoil spread back on top. In order to ensure a stable stream reach after <br />restoration, a longitudinal profile of the stream should be taken at the area <br />of the proposed catchment basin prior to excavation. Please feel free to <br />contact me with any questions.
