Nestor Channel Maintenance
Map 134
The project provides for the periodic removal of sediment, hydrophytic vegetation, trash, and debris from a concrete-lined storm water channel in Nestor. The Project will temporarily affect 0.12 acre of errant wetland vegetation that is growing on accumulated sediment within 603 linear feet of cement drainage channel.
Pursuant to the 401 the loss of pollution assimilation functions will be mitigated by the retrofitting of an existing storm drain inlet with a Curb Inlet Filter in the same neighborhood as the channel. The location of the Curblet Inlet Filter is shown here.
