1.0 INTRODUCTION
The Property known as Parcel #602-353-023 is owned by Keith and Tammy Berry. The
property is located in Brinnon, Jefferson County, Washington in the southwest quarter of
Section 35, Township 26 North, Range 2 West W.M.(Figures 1,2). The property consists
of 7.67 acres on the east side of Highway 101 adjacent to Hood Canal (Figure 3).
The property was purchased by the present owners from a relative (Mrs. Berry's
grandmother} who previously lived on a home on the property. Several years ago, the
home was damaged by a fallen tree, became unusable and was recently removed by the
Berry's in preparation for construction of a new house on the property.
Westech performed a wetland delineation on the property in December 2002. The
delineation found that there was a Class I wetland on three sides of the property and that
continued residential use would require a reduction of the buffer zone. That report
recommended a reduction of the buffer zone to 75', or 50 percent of the buffer required
for a Class I wetland. Buffer averaging will also be necessary at the entrance of the
property in order to provide access to the parcel, since the entrance road runs along a
slough to the west of the property.
The property includes a salt marsh, adjacent to Hood Canal, a buffer zone (recommended
to be 75' and a homesite. The buffer zone had grown up in blackberry bushes and these
have been removed, perc holes installed to test for drainfield suitability, and the area has
been revegetated with a native bluegrass and ryegrass mix to stabilize the area against
erosion and sedimentation. A portion of the homesite has also been revegetated with
native grass.
The Project Site has areas determined to be Critical Areas under the Jefferson County
Uniform Development Code (Jefferson County Uniform Development Code Section 3). The
Code requires preparation of a Buffer Enhancement Plan in order to reduce standard buffer
widths for development adjacent to wetlands.
Site inspections were performed for development of this Plan by Dr. Bradford Shea on
December 31, 2002 and January 2, 2003. On December 31, the property owner, Mr.Keith
Berry met Dr. Shea on the Site to go over position of the planned new residence.
Biological observations conducted by Dr. Shea indicate that the wetlands and buffer zone
portions of the site has good wildlife habitat value. Signs of deer and elk were observed
and have been reported on the Site. Salmonid fish utilize the sloughs and channels in the
marsh. Numerous songbirds utilize the marsh in season. Small mammals undoubtedly
utilize the Site.

2.0 JEFFERSON COUNTY COMPLIANCE REQUIREMENTS
The property owners of the Site intend to apply for a building permit to construct a single
family, two bedroom residence and associated drainfield. Approximate locations of the
proposed home and drainfield are shown in Figure 3.
Due to a number of years of non-use of the previous residence, the previous lawn area of
the home had grown up in non-native blackberry plants and other weedy species. This
included portions of the buffer zone. Those bushes were removed by the owner during the
process of digging drainfield test pits and the area has been replanted with a native grass
mixture.
The County has indicated that the landowner must develop a Buffer Restoration and
Enhancement Plan which includes stabilization of soils in the affected area and revegetation
with trees, shrubs and herbaceous vegetation. The Buffer Restoration and Enhancement
Plan set forth in the next section of this document has been developed by biologists at
Westech Company to comply with these requirements. Since the Plan will affect the
utilization of the area by wildlife, special provisions have been included, requiring some
long-term monitoring.
Westech Company has coordinated with the property owners, Jefferson County's
representative (Mr. Jerry Smith) during the preparation of this Plan. The County has
indicated that it will be acceptable for a contract to be developed between the landowners
and the County for implementation of the Buffer Restoration and Enhancement Plan. The
terms in that contract will be based on the recommendations of this Plan and on other
conditions that the County and the landowner may agree on.
WT813PLN.ENH/011603gbs 2
3.0 BUFFER RESTORATION AND ENHANCEMENT PLAN
This Buffer Restoration and Enhancement Plan is intended to comply with the requirements
of the Jefferson County Uniform Development Code, Section 3, Wetlands. As such, the
Plan includes information and recommendations on soil stabilization, revegetation and
tree/shrub placement. Timing of implementation is also discussed, since the contract with
the County is anticipated to contain dates for compliance which indicate completion of
certain actions.
3.1 Soil Stabilization
Prior to construction, soils should be stabilized through placement of a silt fence, at least
18 inches in height along the homesite/buffer zone edge extending from the south property
line, surrounding the homesite on three sides (east, north and west). Additional erosion
control measures should be in place on any exposed soils which have not been replanted
prior to commencement of the rainy season (generally October 1 to April 30). Thus, all
exposed soil should be either:
1) Covered with impermeable surface (house foundation, driveways etc.),
2) Replanted in ground cover or shrubs, or
3) Treated for erosion control using straw bales or plastic ground sheeting.
These additional measures should be in place before October 1, 2003 (or immediately
following any grading or other ground-disturbing activities which occur prior to the end
of the 2002-2003 rainy season), in order to comply with the County requirement for soil
stabilization.
3.2 Revegetation
Revegetation of disturbed areas in the buffer zone should be accomplished with native
vegetation. Native standing trees (whether living trees or snags) in this area should not
be disturbed. Removal of lower limbs of trees is appropriate in some cases to improve
view, however, such removal should specifically be checked with the county representative
or with a qualified biologist.
All new plants will be vulnerable to the stresses of the local environment (which may
include salt spray, salty conditions in the root zone, wind and periodic wet soil conditions.
This may cause loss of plants (mortality). Additional stress will result from the presence
of grazing by native deer and elk. The plan thus compensates for these factors by
recommending additional plantings to compensate for mortality, temporary fencing during
establishment of plants, and periodic monitoring to ensure success.
WT813PLN.ENH/011603gbs 3
Native vegetation recommended to revegetate the 75 foot buffer zone includes but is not
limited to the following (see also Table 1 for quantities and a more detailed listing):
Trees:
Western Red Cedar
Red Alder
Yellow Twig Dogwood
Red Stem Dogwood
Shrubs:
Evergreen Huckleberry
Sword Fern
Oregon Grape
Salal
Wild rose
Herbaceous Plants:
Ferns
Bluegrass
Ryegrass
The revegetation of the buffer zone should be limited to native plants (within 75 feet of
the wetland). The property owners should work with a qualified nursery specialist or
biologist to select listed plants (see Table 1). Native vegetation is also preferred but not
required on the homesite outside the buffer zone. A list of shrub and herbaceous layer
vegetation which will be replanted in the buffer zone is given in Table 1.
3.3 Tree Enhancement Plantings
In order to enhance the buffer zone, native tree specimens will be replanted to compensate
for the proposed reduction of the buffer zone. Additional, trees will be planted as an
insurance against tree mortality which may occur. A recommended total of 69 trees are
recommended in Table 1. With additional planting for mortality, 85 trees will thus be
planted. The trees will be planted in four tree/shrub areas as indicated in Figure 3.
Additional trees may be planted within the shrub areas in groupings to help ensure that
sufficient become established and survive to become mature trees.
Trees to be planted are primarily western red-cedar (Thuja plicata) which is recommended
for all four areas. Vine maple and red alder are recommended more for the eastern areas,
where they will provide valuable habitat without extensive screening of the house views.
Redstem dogwood is also recommended for all four areas. Crabapple is recommended to
the north and west (areas 3 and 4) since these plants generally do well in settings near the
edge of forested areas.
WT813PLN.ENH/011603gbs 4
A recommended layout of tree plantings is shown in Figure 3. All replanted trees should
be native specimen trees, which are in good health. Heights are expected to vary. Western
red cedar should be at least three feet in height to help ensure maximum survival rate.
The recommended tree species (including quantities and locations as per Figure 3) are
listed in Table 1.
3.4 Implementation and Timing
Native vegetation will survive best if planted in fall or spring when frequent rainfall makes
watering largely unnecessary. Given the time of this report preparation, the first
opportunity to plant would be in the spring of 2003. Both trees and shrubs should be
planted at this time. Native groundcover plants can also be transplanted or planted at this
time. The area should be revegetated to specifications of this plan during the spring and
fall of 2003.
Seeding for groundcover within the homesite other than grasses for erosion stabilization
should await completion of construction activities. Planting of any and all trees and shrubs
in the buffer zone can be carried out at any time during the seasons listed above.
The construction schedule is not firm at this time and depends on contractor schedules as
well as other factors, however, the homeowner would like to begin construction in April
2003 if permits can be obtained in a timely manner. Replanting should be completed as
soon as possible following completion of construction of the residence. All replanting
should be completed within 90 days of construction, unless such a timeframe results in
planting during dry summer months (generally mid-June through mid-September).
3.5 Fencing and Monitoring
Establishment of temporary fencing will be necessary to protect new plants against grazing
by deer and elk until those plants are well established. This is estimated to require 2-3
years following planting. Fencing should be sturdy field fencing at least 5 feet in height
(no higher than six feet). Fencing should be secured by wooden posts measuring at least
4"x4"and set solidly in the ground with a post-hole digger. Posts may be set with a small
amount of concrete to maintain stability, however, such concrete should not be extensive
since it must be later removed and disposed of off-site, as must any treated wooden posts
(for the temporary fences).
Fencing may be placed around each grove of trees (areas 1-4). With permission of the
Washington State Department of Fish and Wildlife, fencing may alternatively be placed at
the outside edge of the buffer zone, for a period not to exceed three years, following which
time it must be removed. Permanent fencing of a non-barrier type, such as a three foot
split rail fence may be erected at the outside edge of the homesite (inside edge of the
buffer zone).
WT813PLN.ENH/011603gbs 5
Monitoring of plant success should be carried out twice annually by a qualified biologist
for a period of three years following planting. Brief letter reports should be filed with the
County annually.
• 3.6 Compliance Agreement
A compliance agreement will be enacted between the homeowner and Jefferson County.
That agreement should specify timing of planting, general planting techniques and any
other required compliance conditions. In the following section (4.0), various
recommendations are made which may be used as the basis for conditions in the
compliance agreement.
•
WT813PLN.ENH/011603gbs 6
4.0 RECOMMENDATIONS
In order to properly implement the elements of the Buffer Enhancement and Restoration
Plan above, the County has indicated that a Compliance Agreement (contract) should be
implemented by the property owner and the County. The terms of that agreement must
also be acceptable to the Homeowner and to the Washington Department of Fish and
Wildlife.
The following recommendations are made with respect to proceeding with development of
the compliance agreement and to further development of the property:
1) Silt fences should be placed along the limits of grading (homesite-buffer
boundary) to stabilize soils. No equipment should henceforth be used
shoreward of the silt fences (see Section 3.1).
2) Revegetation of groundcover and bushes in the buffer zone and homesite
implemented as described in more detail in Section 3.2. Native vegetation
should be used and hand planting methods should be used. Native grasses
should be seeded to prevent erosion (this has already been accomplished by
the property owner).
3) Plant trees in the buffer zone according to the plan map in Figure 3 and
descriptions in Section 3.3. Species mix for shrubs within each area should
be determined prior to planting. We recommend species locations as set out
in Table 1, however, minor variations may occur. Trees should be grouped
in four groupings as shown in Figure 3.
4) Leave all remaining trees in the buffer zone in their present condition except
for limited limbing to improve view and aesthetics (some of these are non-
native trees, some of which can be removed with approval of the county) .
Limbing of lower limbs is permissible in existing trees.
5) Implement #1-4 during the spring and fall of 2003. Implement the fencing
protection prior to or at the time of planting. All planting will be
accomplished prior to the County signing off on the final building permit.
In addition, Jefferson County may require that the following be added to any
agreement with the property owners:
8) No structures will be built in the buffer. The buffer will remain completely
natural during and after completion of work. Subsequent work will be
allowed in that area without approval of the County (except establishment
of a trail between the homesite and wetland edge, made of natural materials,
with a three foot maximum width. No work, including fence restoration
shall be permitted in the wetlands without further County approval.
WT813PLN.ENH/011603gbs 7
9) The trees and shrubs to be planted are for mitigation for fish and wildlife
habitat which is being lost due to construction of the residence and reduction
of the buffer zone size. Erosion control and control of water runoff (through
drywells and other drainage structures) are also part of that mitigation.
Implementation of these recommendations and incorporation of the recommendations into
a compliance agreement is expected to mitigate for the effect of buffer reduction. The net
result is expected to constitute an adequate enhancement of fish and wildlife habitat.
