4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: *
Our community pond receives storm water from upstream parts of the town. The pond drain stack dumps in a creek directly behind our fence. During the October 2021 storm, we received
excess water that breached the pond banks and created extensive erosion in our back yard as water was coming across the road and into our back yard faster than it could drain out of the
pond drain. The force of the water knocked an 8 foot section of 6 foot tall privacy fence down, washed all of our mulch and gravel out of our landscaped area in the back yard, and created
a hole in our back yard where water was eroding the bank far enough back to create a hole under our fence approximately 3 ft wide, 3 ft deep, and 20 ft long. The project is part of our
fenced in backyard. See attached photos/video in link https://www.icloud.com/sharedalbum/#Bl655Z2WMJ8Hcgr
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?
Yes No Unknown
u
4f. List the total estimated acreage of all existing wetlands on the property:
0

4g. List the total estimated linear feet of all existing streams on the property:
65
4h. Explain the purpose of the proposed project:"
Installing gabion baskets would rebuild the stream bank and installing a dissipator pad under the pond drain to eliminate further erosion into our back yard. Making the emergency spillway
deeper will allow for excess water flow to remain contained.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:"
Using a sump pump, we will pump all water from the basin where the pond drain daylights. We will also support the stream with plywood and rebar stakes will be used as temporary trench
braces to prevent water and soft soils from entering the work site. We will use a mini excavator to dig the loose soil and pea gravel that has washed down from the back yard during heavy
storms. Excavation will also shape the stream bank for setting the gabion baskets linearly and establishing the elevation for the base material and gabion mattress. This excavated
dirt/gravel/soil will be set aside to be used as fill for the back yard. Once excavation is done and the elevation is set, we will back fill with a #57 gravel base and compact to a thickness of
approximately 6". The base will be sloped slightly back towards the streambank that will be behind it. We will lay a geotextile fabric down over the top of the base and run back up the
streambank. The gabion basket will be set and the mattress set in front. The mattress will be filled with 4"-8" angular fill and tied, then the gabion will be filled with 4"-8" fill wit corner
stiffeners installed and tied. The geotextile fabric will be folded over the top of the gabion and the fill will be placed back behind the gabions and the geotextile fabric will be cut along the
top of the gabions. At this point, the temporary trench braces will be removed and the riprap for the dissipator pad will be placed at the bottom of the stream where the pond drain daylights.

openings. It shall be fabricated and finished in a workmanlike
manner, as determined by visual inspection, and shall conform
to this specification.
11. Sampling

properties of welded wire fabric shall be obtained by cutting
from the finished fabric a full -width section of sufficient length
to perform the testing. Samples for determining the mechanical
and physical properties of coated wire used for spiral binders,
lacing wire, and stiffeners shall be selected at random in
sufficient number to perform the testing.
12. Number of Tests
12.1 Perform a minimum of four tests for conformance to
tensile strength of metallic -coated wire, weld shear strength,
wire and fabric dimensions, metallic coating weight, PVC
coating thickness, adhesion of PVC coating, and mandrel bend
from each 200 000 ft` (19 000 m'') of fabric or remaining
fraction thereof. Perform a minimum of four tests for conform-
ance to tensile strength , wire dimensions, coating weight, PVC
coating thickness, adhesion of PVC coating, and mandrel bend
from the wire accessories used with each 200 000 ft` of fabric.
The lot will be acceptable if the results of all four tests conform
to the requirements.
13. Test Methods
13.1 Metallic Coating Weight —Perform coating weight
tests in accordance with Test Methods A 90/A 90M or A 428 as
applicable. For coating weight tests on wire of the welded wire
fabric, secure multiple lengths between welds, including both
longitudinal and transverse wire, and cut no closer than Va in.
(6.4 mm) from any weld. The combined length shall be 12. in.
(305 mm), minimum, but preferably about 24 in. (610 mm).
13.2 PVC Coating Thickness:
13.2.1 Determine the thickness of the PVC coating on an
individual piece of wire removed from the fabric.
13.2.2 Determine the diameter of the metallic coated wire
after stripping the PVC coating by chemical means. Determine
the thickness of the PVC coating by scraping the coating from
one side of the wire and measuring the reduced diameter with
a micrometer. The thickness of the coating at this point is die
difference between the measurement thus obtained and the
measured diameter of the metallic coated wire. Determine the
thickness of the coating at right angles to the first determination
in a similar manner. When removing the PVC coating by
scraping, take care not to remove any of the metallic surface.
13.3 PVC Adhesion Test —Make two cuts parallel to the axis
of the wire through the coating, approximately IA6 in. (1.6 mm)
apart, at least '/: in. (12.7 mm) long. With a knife, peel back a
section of the coating between 1/8 in. (3.2 mm) and 114 in. (6.4
mm) long to produce a tab. Attempt to remove the IA( ­in. strip
of coating by pulling the tab. The lot shall be acceptable if the
coating breaks rather than separates from the core wire on all
four specimens.
13.4 Weld Shear Strength of Fabric:
13.4.1 Scope —This test method covers the procedure for
determining the strength of welded intersections of welded
wire fabric.
13.4.2 Significance and Use —The weld shear strength is a
measure of the ability of welds in wire fabric to resist the forces
imposed on the wires tending to pull them apart.
13.4.3 Apparatus —Use a testing fixture such as shown in
Fig. 5, which is intended to stress the vertical wire close to its
centerline, and to prevent rotation of the horizontal wire. This
fixture can be used in most tensile testing machines and should
be hung in a ball and socket arrangement at the center of the
machine. This or a similarly effective fixture designed on the
same principle, is acceptable (see Specification A 185).
13.4.4 Test Specimens— Test specimens shall be obtained
by cutting, from the finished fabric, a full -width section
including at least two transverse wires.
13.4.4.1 The transverse wire of each specimen shall extend
approximately I in. (25 mm) on each side of the longitudinal
wire. The longitudinal wire of each test specimen shall be of
such length below the transverse wire so as to be adequately
engaged by the grips of the testing machine. It shall be of such
length above the transverse wire that its end shall be above the
centerline of the upper bearing of the testing device.
13.4.4.2 A test specimen shall consist of four welds selected
at random from one transverse wire for weld shear strength. If
the width of the fabric is such as to not include four welds that
are suitable for testing, additional welds shall be taken from a
second transverse wire to total four. (Welds at the edge wire are
excluded from testing as there is no overhang to permit proper
testing). If the average weld shear strength from the four
specimens does not conform to the requirement of 7.2, test all
the welds across the width (excluding edge welds) on one
transverse wire, or on two transverse wires if some of the initial
specimens were from the second transverse wire.

and double -looped with spacing not to exceed 6 in. Secure ends
sk ith two complete revolutions and finish with a one-half hitch.
13.5.2 Spiral Binders —Spiral binders shall pass through the
openings. Securely tie at both ends to prevent unraveling when
a load is applied in accordance with the minimum strength
requirements of 7.3.
13.5.3 Mount each of the two panels on a loading machine
with grips or clamps such that panels are uniformly secured
along the full -width. The grips or clamps shall be designed to
transmit only tension forces. The load then will be applied at a
uniform rate not exceeding 50 lb/s until maximum load is
obtained. The maximum load is reached when a drop of
strength is observed with subsequent loading.
