CROSS-SECTION
INSPECTION AND MAINTENANCE:
This consists primarily of two components, stream stabilization
structures (J -Hooks, Cross vanes, etc.) and planting of the stream
banks and riparian areas. In the event that the stream structures
shift, wash away, settle, or otherwise physically cannot function as
designed, contact the area NRCS Agent. If the new plantings
experience a mortality rate of greater than 25%, the dead/dying
plants will need to be replaced.
PERMANENT SEED MIX:
APPLY AT 15 LBS PER ACRE OF DISTURBANCE (per specifications of
seed supplier):
ERNST CONSERVATION SEED MIX ERNMX-178 (FLOODPLAIN MIX)
WHICH INCLUDES THE FOLLOWING SPECIES:
Fox Sedge, Partridge Pea, Dear Tongue, Little Bluestem, Virginia Wild

Wood, Big Bluestem, Silky Dogwood, Switchgrass, Indiangrass,
Staghorn Sumac, Showy Tick Trefoil, Purple Bergamot, Black Eyed

Common Name Scientific Name Rate per Acre Optimal
Planting Dates
Rye grain Secale cereale 30 lbs Aug 15
-May 15
Browntop millet Urochloa ramosa 10 lbs May 15
- Aug 15
Seedbed Preparation:
Disturbed soils within riparian areas will be amended to provide an
optimum environment for seed germination and seedling growth.
Surface soils will be loose enough for water infiltration and root
penetration. Lime will be added to the soil to ensure a pH level
between 5.5 - 7. Fertilizer (18-46-0) will be added to nutrient deficient
areas. All riparian areas will be raked to loosen compacted soil prior to
seeding.

4. GEOTEXTILE CLOTH WILL BE PLACED AGAINST THE OUTSIDE EDGE
OF THE THE VANE ARM BOULDERS.
5. THE VANE ARM CUT-OFF SILLS WILL BE CONSTRUCTED
PERPENDICULAR TO THE ARM ANGLE TO PREVENT THE
