Topsoil. It is our error that we stated that topsoil is to be stockpiled with in the set back areas of arty of
the excavated antes. These set bads ana3s are to remain undisturbed areas, and are not to be a part
of the excavating operation in anyway. Topsoil at the Overall sde varies by arce. WAhin area "B" very
limited amount of topsoil exists. In 60% of the aroma, no topsoil exists. The topsoil that does exist is to
be stockpiled on the area just to the south of the Old Railroad Grade Road. Because area "B" is small
and its perimeter is to be reclaimed as a first step of the Overall excavation, said topsoil will be used to
reclaim the perirrre<er areas. Area "A" contains from zero inches of topsoil to 14" (depth) d topsoil. As
this area is opened the topsoil will be stodkpiled on the interior area. A portion of the topsoil will be
used to red~m the perim~er areas. If any topsoil remains after reclaiming the perimeter, d will be
stockpiled at the staging area currently used for the Seahorse Pond Gravel Pit. This loption is 0.5
miles east along the Old Railroad Grade Road, and is on Seahorse Ranch property. ft is undetermined
if any extra topsoil material will result from this area. Area "C" contains from 2" to 20" (depth) of topsoil.
The topsoil will be stockpiled on the interior M the area when it is opened. A portion of the topsoil will
be used to reclaim the perimeter of the area. Any remaining topsol will be stockpiled the same as
noted for area "A".
Tomichi Creek setbacks, see drawing Exhibit "B". The Corps of Engineers and Seahorse Ranch
agreed to setbacks along the Tomichi Creek. The settx'kcks are 75'-0' from the high water mark for this
area of the crcek The exception to this is the northeast comer of area "B". As shown on the drawing
the set balk and Overall area of this comer is to bean undisturbed area. This arce contains a wetland.
In detemrining an aooeptable setback distance, a consideration was given to the fad that the perimeter
of the exgvated area would have a 3.0 to 1.0 slope area. And that this area would lxx reclaimed aS
soon as it was exk~vated. The slopes with in the undisturixxd setback areas varies, but is very shallow.
Using 10'-0" horizont~ measurements the slope is rxR greater then 2" for each 10'-0". This sloping
toward the Tomichi Creek The agreement with the Corps of Engineers is that the 75'-0" setback area
is to remain undisturbed. The riverbanks are not to be graded or other wise structurally draar>ged. This
any of the Tomidti Creek corrtairrs relatively high banks and has a history M rrd flooding. ft has been
agreed to add addfional cottonwood trees and native willows to these setbadk areas.

Depth of topsoil, perimeter areas. Topsoil will be placed in this areas to a depth of 12".
Revegetation Plan. The revegefation plan consists ~ the revegetation of the perimeter sloped areas,
and as stated some of the setback areas. These areas will be revegetated using three variations of
plantings. These areas will be seeded with grasses that are common to the existing connecting hay
meadows. The grasses consist of Redtop, Amerign Sloughgrass, Bluejcnt reedgrass, Slender
wheatgrass, Quackgrass, Canary reedgrass and Timdhy. These areas will be seeded during the fall
season after the slope has been created. The seeding method is to be "broadcast". Nanowleaf
cottornNOOd trees are to be planted along the outer edge of the sloped areas. These trees are to be
concentrated along the Tomichi Creek and Seahorse Ranch boundary arms. The trees will not be
planted closer then 10' - 0" a part, and may be planted further a part depending on the location.
Sandbar willow is to be planted at various locations along the entire perimeter of the excavated areas.
These willows will be planted using a duster approach. All tree and willow planting will take place in the
spring following the creation of the sloped areas. It is to be noted that this revegefation plan is designed
to restore the area to exstng hay meado~nrs and riverbank habitat around the newly created porxi and
lake.
Lake sizes. See drawing "F".
Setback arms. As described above these areas an; to remain undisturbed.
Perimeter slopes. The slopes for all perimeter areas are to be 3.0 to 1.0 to a depth of 10'~ of water.
Slopes beyond the 10'-0" depth are to be 2.0 to 1.0.
