ARO has reveiwed. Issued as requested with the following: Sediment and erosion control measures must be implemented prior to
construction and maintained on the sites to minimize sediment in downstream areas. Seeding for a temporary cover of wheat, millet,
or similar annual grain or permanent herbaceous cover should occur on all bare soil within five (15) days of ground disturbing activities
to provide long-term erosion control. Erosion control matting should be used in conjunction with appropriate seeding on disturbed
soils in steep slope and riparian areas. Matting should be secured in place with staples, stakes, or, wherever possible, live stakes of
native trees. Straw mulch and tall fescue should not be used in riparian areas. 7. Under no circumstances should river rock, sand or
other materials be dredged from the stream channel under authorization of this permit except, if necessary, in the immediate vicinity of
the canoe access area. Streambed materials are unstable in flowing-water situations and are unsuitable for bank stabilization. In-
stream dredging has catastrophic effects on aquatic life and disturbance of the natural form of the stream channel can cause
downstream erosion problems. The natural dimension, pattern, and profile of the stream upstream and downstream of the permitted
area should not be modified by widening the stream channel or changing its depth. 8. Stabilization measures should only be
applied on or near new disturbed sites, leaving other stable stream bank areas in a natural condition. Grading and
backfilling should be minimized and tree and shrub growth should be retained where possible to ensure long-term availability of
stream bank cover for aquatic life and wildlife. Backfill materials should be obtained from upland sites except in cases where excess
streambed materials are available. Berms shall not be constructed because they block the floodplain, constrict and accelerate flood
flows, and often fail and sometimes impede drainage during large
