P03 - Attachment 6 - Wetland Depression Design Specifications.pdf

Specifications for the Proposed Ditch Plugs, Depressional Wetlands, and Hummocks:

Side slopes for the ditch plugs are to be 5 to 1. Side slopes for the depressional wetlands 10 to 1.

Side slopes for all hummocks are to be 5 to 1. Top dressing consists of topsoil that was removed prior to excavation and then reapplied. All hummocks and plugs would be seeded and mulched after construction.

Cross sections are at wetland center.
