DISCLAIMER
WSP Environment& Energy has prepared this critical areas assessment and mitigation report for
use by Mr. Lou Slagle. The results and conclusions are based upon information provided by
Olympic Wetland Resources, Inc. (April, 2000) and public domain information (e.g. U.S.
Geological Survey 7.5' topographic quadrangle maps, Natural Resources Conservation Service
Soil Surveys, and air photographs from various sources), as well as on-site reconnaissance, data
collection, and analyses by standard methods. This report represents the best professional
judgment of WSP Environment& Energy.

I. INTRODUCTION
WSP Environment & Energy (WSP) was retained by Ernest (Lou) Slagle to assist with the
wetland buffer mitigation plan and storm water dispersion portions of Jefferson County
(hereafter "County") permits (Manufactured/Mobile Home Installation Permit and Building
Permit) associated with replacement of a manufactured home on his property (Case #: BLD00-
00036).
A. Project Site
The Slagle property is located at 2203 Beaver Valley Rd, Port Ludlow, WA 98365 (Jefferson
County Tax Parcel #82 1 1 82003) (Figure 1). The project site abuts Ludlow Creek and its adjacent
wetland. The location of the new home site lies outside of the stream buffer setback area (100
ft), which is itself subsumed within the creek's adjacent wetland. However, the project lies in
close proximity of the wetlands adjacent to Ludlow Creek (Figure 2, Olympic Resources
(2000)). According to the Jefferson County Manufactured/Mobile Home Installation permit #
BLD00-00036 that was received in January 2000, the County has required a setback of 75-feet
from the delineated wetland edge, with the exception of the existing slab footprint for the
proposed manufactured home, which is allowed to have a setback of 67 feet. The County has
also required that this 75 ft and 67 ft wide area shall be permanently maintained as a wetland
buffer. The County has further stipulated that the buffer will be planted with native trees and
shrubs as mitigation to offset any potential impacts to the wetland from the Slagle project.
B. Project History
A wetland delineation report dated April 2000 was prepared by Olympic Wetland Resources, Inc
for the Slagle property. On August 2, 2008, Dr. Lyndon Lee of WSP completed a
reconnaissance of the Slagle property and confirmed the general accuracy of Olympic Wetland
Resources 2000 delineation. In addition, Dr. Lee reviewed County requirements for the buffer
and discussed an approach for designing and planting the buffer area with the Slagle's. The
following mitigation plan was designed to follow condition requirements set forth by Jefferson
County regarding permits associated with case #: BLD00-00036 and, to the extent possible, be
compatible with the Slagle family's goals for use of the buffer area.
II. PROPOSED MITIGATION
A. Mitigation Site Location and Geometry
The proposed mitigation site (buffer area) will be located on the Slagle property, generally west
and north of the new house structure (Figures 1 and 2). Proposed management of the buffer will
include installation of a diverse native plant community east/north of the wetland boundary and
within the designated buffer area. Approximately 0.78 acres will be planted in a 67- 75 foot wide
band along the wetland boundary(Figure 2, not drawn to scale).
41111 I
B. Existing Conditions at the Mitigation Site
The proposed wetland buffer mitigation area consists of cleared land dominated by bare mineral
soil and native and non-native grasses. Modal soils are mostly fill material. Soils on adjacent
lands are mapped by the NRCS as Everett gravelly sandy loam and McMurray and Mukilteo
Peat.
C. Proposed Mitigation
A setback of 75 ft and 67 feet around the edge of the existing slab footprint for the new home
will be created along the wetland edge on the Slagle property. This area will be permanently
maintained as a vegetated buffer. Consistent with County requirements, the eastern perimeter of
the buffer will be delineated by a plant (and prominent) line of native trees. In addition, an array
of native trees, shrubs, and grasses will be planted within the buffer to increase hydrologic,
biogeochemical, plant community, and faunal support/habitat functions of the buffer area. The
species and quantities of plants selected for planting within the buffer (planting take-offs) are
offered in Table 1. Native species which provide fruits may also provide a foraging source for
wildlife. In addition, consistent with the Slagle family's goals, many of the species in Table 1
produce edible fruits (e.g. red elderberries, Indian-plum, salal, red huckleberries, evergreen
huckleberries,black and red raspberry, Pacific crab apples, and thimbleberries).
Acquisition of planting materials should align with Table 1 to the greatest extent possible. As
with all native plantings, species composition offered in Table 1 may need to be slightly adjusted
depending on availability of plants. Nevertheless, the total numbers of trees (156) and shrubs
(195) specified for the area will be met. If any of these species are not available, a similar
number and type of native plant will be obtained. Specifically, tree species that are candidates
for substitution and which are not listed in Table 1 include: Oregon white oak (Quercus
garryana), Sitka spruce (Picea sitchensis), shore pine (Pinus contorta), and Pacific madrone
(Arbutus menziesii). Shrub species that may be substituted are: Ocean spray (Holodiscus
discolor), Pacific ninebark (Physocarpus capitus), red flowering currant (Ribes sanguineum),
and snowberry(Symphocarpos albus).
D. Construction Sequencing
Planting will be implemented by the Slagle family. Plants should be installed during the interval
mid October to late November, 2008, when conditions are optimal for plant survival. If
necessary, infill planting will occur in Spring 2009, before April 15th. The buffer site will be
prepared for planting by removing all debris (metal roofing, lumber piles, etc.) and by discing the
area to break up the existing turf and loft the soil. Beyond the initial discing to prepare the
planting area, no filling, grading, clearing, or other alteration of the wetland or its buffer is
necessary or allowed.
Prior to any site preparation activity (e.g., discing the buffer for site preparation), a sediment
fence shall be installed at the wetland edge (Figure 3). The minimum height of the top of
sediment fence shall be 2 feet and the maximum height shall be 2.5 feet above the original
4
•
ground surface. The sediment fence shall be buried in a trench to a minimum depth of 5 inches
below the ground surface. The trench shall be backfilled with soil and these soils shall be
compacted over the buried portion of the sediment fence, such that no water flow can pass
beneath the fence. Any damage to the sediment fence shall be repaired immediately. Sediment
deposits on the up-gradient side of the fence shall either be removed when the deposit reaches
approximately one-third the height of the sediment fence, or a second sediment fence shall be
installed.
After discing the buffer area which will be planted, trees will be installed at approximately 15
feet on-center (o.c.) spacing throughout the buffer. Shrubs will be planted in masses or clumps
of three to fifteen plants at 3 approximately feet o.c. spacing. Approximately 12 - 15 feet of
space will be left between the clumps to maneuver equipment (e.g. weed whackers) for routine
weed control. Trees and shrubs will be installed following standard methods as detailed in
Figure 4. A native grass seed mixture (50%/50% mix of Festuca rubra and Poa pratensis) will
be had applied throughout the buffer to establish ground cover. Seeded soil will be covered with
a hand applied 4" - 6" lift of sterile (weed-free) straw.
Following plant installation, monitoring will commence with submission of a baseline
monitoring report as described in Section III.B of this report Wetland buffer areas shall be
maintained in their natural condition, however, minor pruning, infrequent mowing or alteration
of vegetation may be permitted as long as the function and character of the buffer are not
diminished.
E. Signage
During construction, wetland buffer perimeters shall be marked with temporary signs at an
interval of one per parcel or every one hundred feet, whichever is less. Signs shall contain the
following statement: "Wetland Buffer — Do Not Remove or Alter Existing Vegetation." As
explained above, along the generally eastern and northern (upland) perimeter of the wetland
buffer, a permanent physical separation along the upland boundary of the wetland buffer area
shall be marked by a prominent line of trees and shrubs.
III. PROJECT TARGETS AND MONITORING PLAN
A. Project Targets, Project Standards and Success Criteria
The following primary targets will be used to measure success of the mitigation project:
Target#1: Establish a native plant community suited to the current conditions of the
mitigation site.
Project Standards:
a. Remove non-native species within the wetland buffer.
b. Plant native trees and shrubs suited to micro-site conditions.
5
• •
Success Criteria:
a. Within five years, there is an established native plant community, consisting of a
minimum of three strata of species including trees shrubs, and grasses.
b. Plant survival after 5 years is no less than 85%.
c. Canopy cover of the all canopy layers of the plant community is >85% after 5 years.
d. Non-native plants make up less than 5 % of any canopy layer(tree, shrub,herb).
Contingency Measures/Adaptive Management:
a. Supplement planting as necessary to develop a plant community with three strata.
b. Replace plants that do not survive to ensure minimum of 85% survival.
c. Install an irrigation system as necessary.
d. Control weeds through mowing,hand removal, weed-eater, or as a last resort, chemical
control.
Target#2: Improve on-site habitat for native faunal species.
Project Standards:
a. Remove non-native species from the wetland buffer.
b. Plant native trees and shrubs suited to micro-site conditions.
Success Criteria:
a. Within five years there is an established native plant community, consisting of a
minimum of three strata of species including trees and shrubs.
b. Canopy cover of the all canopy layers of the native plant community is greater than 85%
after 5 years.
Contingency Measures/Adaptive Management:
a. As stated in Target 1, install supplemental plants as necessary to increase development
of canopy cover. Select alternate species if high mortality rate occurs for any species.
B. Monitoring
Upon completion of the construction and plant installation, baseline conditions will be
documented. Permanent photo-monitoring points will be established. A report with photos, an
as-built map documenting installed plant species and densities, and a narrative documenting
baseline conditions will be prepared and kept on file with the County. The mitigation site will be
monitored over a five (5) year period to ensure the plant community is being restored
successfully. In all years, plant survival rates will be recorded, and a monitoring report with
photo-documentation will be produced. The monitoring reports will be submitted to and kept on
file with the County. Each report will state what corrective actions, if any, are needed to meet
project targets.
6
• •
C. Adaptive Management
Adaptive management will be focused on (1) weeding to control non-native plants within the
buffer, and (2) replacing plants which suffer mortality during the monitoring period to maintain
80 % survival. Specifically:
1. Weed and invasive plant removal will occur, as necessary, but at least two times per year
during the growing season (e.g., April and July). Control of weeds will be accomplished though
a combination of mowing, weed whacking, and as a last resort, application of approved
herbicides
2. If in any given monitoring year it is found that the survival rate is less than 85%, the affected
species will be replanted. If necessary, alternative species and/or alternative site locations or
plant densities may be recommended.
3. A temporary irrigation system can and will be installed if necessary.
IV. STORMWATER MANAGEMENT SYSTEM
A. Roof Runoff
Stormwater concerns from the proposed project are limited to downspouts which convey roof
runoff to the ground around the home. The flow from gutters to downspouts will be maintained
to provide sufficient stormwater dispersion. At each downspout discharge point, roof runoff
water will be directed to subsurface dispersion pipes that will be installed adjacent to the home,
at least 650 feet from the wetland edge. The dispersion pipes (4" diameter) will be installed in a
washed gravel-lined trench that is approximately 2 feet wide by 1.5 foot deep (Figure 5) (WA
DOE 2005). A maximum of 700 square feet of roof area may drain to each dispersion trench.
B. Buffer Restoration Stormwater Management
A sediment fence will be installed along the wetland edge prior to preparation of the site for
planting and will be maintained until grass cover is established (See Section II.D.). In addition,
consistent with discussions offered above regarding planting, the buffer area will be broadcast
seeded with a native mix and then covered with sterile straw.

Introduction
At the request of Lou Slagle, Dixie Llewellin of Olympic Wetland Resources, Inc. conducted a
wetland delineation on April 26, 2000. The 53-acre site is located in Beaver Valley (2203 Beaver
Valley Road)west of Highway 19. This wetland survey is precursory to a building permit
application for a manufactured home installation to be located near the wetland. The results of this
report will also affect the placement of an existing structure, which has been referred to as "Fred's"
mobile home (letter to Lou Slagle March 29, 2000 from Michelle Farfan, Assistant Planner Jefferson
County Department of Community Development). The portion of the wetland surveyed lies directly
west of the existing mobile homes. The scope of this delineation was to determine the area of the
wetland and buffers that would affect final placement of the manufactured home.
The wetland will be considered a Class I wetland due to the large size, forest cover, and connections
to a fish-bearing stream.
Development adjacent to wetlands or within wetland buffers is subject to regulation standards of the
Jefferson County Critical Areas Ordinance and the Corps of Engineers.
Methodology
Prior to the fieldwork, the following maps were consulted:
• National Wetland Inventory Maps
• U.S. Geological Survey Maps
• Jefferson County Critical Areas Maps(Figure III Appendix)
• Soil Survey Maps of Jefferson County(U.S. Soil Conservation Service 1975) (Figure IV Appendix)
Fieldwork to determine the actual wetland boundaries was conducted according to the methodology
outlined in the Washington State Wetland Identification and Delineation Manual(Department of Ecology
#96-94). Washington Administrative Code requires that all wetlands within the State of Washington be
delineated using this manual.
Examination of three parameters is required for a positive wetland determination: hydric soils, hydrophytic
vegetation, and hydrology. For an area to qualify as a jurisdictional wetland it must have a positive
indicator from all three parameters. All wetlands which meet the criteria, regardless of size, may be
federally regulated.
Lou Slagle Wetland Report 1 Olympic Wetland Resources,Inc.4/00

Classification and Jefferson Critical Areas Ordinance
Wetland categorization was determined using the Washington State Department of Ecology Wetland
Rating System(publication #91-57 October 1991),which assigns a numerical value to any given wetland
according to wetland size, quality of surrounding buffers, vegetation diversity, wetland types, and habitat
value. Wetlands are rated as entire systems and quite often extend beyond project boundaries.
All wetlands are regulated by the most recent Jefferson County Critical Areas Ordinance(1995)
wetlands are regulated if they meet certain sizes and classifications.
Soils
A hydric soil is a soil that formed under conditions of saturation, flooding, or ponding long enough
during the growing season to develop anaerobic condition in the upper part. Hydric soils favor the
growth and regeneration of hydrophytic vegetation. The indicators for this type of soil include low
chroma, mottles, gleying and high organic content within the upper 32 inches of the soil profile. Holes
were dug on the site and soil colors(including value and chroma)were recorded in the top 16 inches to
determine wetland soils. Soil colors were analyzed using the Munsell Color Charts (1992).
Vegetation
Wetland plant species must constitute greater than 50% of the total vegetation present to meet the
qualification as a site dominated by hydrophytic vegetation. Dominance of plant species is determined by
calculating actual aerial cover within a 30-foot radius for trees, a 10-foot radius for shrubs and a 6-foot
radius for the herbaceous layer at each data point. Each species was recorded and given a rating
according to its indicator status as described by the United States Fish and Wildlife Service,National List
of Plant Species that occur in Wetlands: Northwest(Region 9).
Hydrology
Wetland hydrology is defined as"areas that are periodically inundated or have soils saturated to the
surface at some time during the growing season". Areas must have seasonally inundated or saturated soils
at least 12.5% of the growing season. 1 Indicators of hydrology include visual observation of inundation
or soil saturation, water-stained leaves, cracking at the soil surface or sediment deposits. Positive signs of
hydrology are often absent during the summer and fall months but can be inferred if there are positive
indicators of hydric soil and hydrophytic vegetation.
Findings
Wetland Edges
Boundaries were determined by establishing data points within the wetland, which contained positive
indicators of all three of the wetland requirements; and data points outside the wetland, where wetland
soils, hydrology or hydrophytic vegetation were not present. Data point locations are shown on the
Wetland Delineation Map in the Appendix(Figure II).
' The growing season is defined by the Jefferson County soil survey as March 12 to November 25 in or near Port
Townsend. Hydrology must be present for 12.5%(20 days) of these 258 days for an area to qualify as a wetland.
Lou Slagle Wetland Report 2 Olympic Wetland Resources,Inc.4/00
2000-52
•
On April 26, 2000 wetland edges were flagged with orange Wetland boundary tape (Al through
All) at 25 to 50 foot intervals. All data points and soil test pits were also flagged. Information for
all data points was recorded and is included in the Corps of Engineers Data Forms in the Appendix.
Wetland boundaries, data points, and approximate structure locations are shown on the Wetland
Delineation Map in the Appendix (Figure II).
The natural wetland buffer has been altered 8 to 10 years ago by adding a berm containing fill to
accommodate the structures (conversation with Lou Slagle 11/15/99). There is a definite
topographic rise between the fill and the wetland to the west, as well as a distinct plant community
change. Soils, hydrology, and plant change also verify the wetland/upland edge, which generally
runs along the base of the berm. On the northern edge of the property, the soil and wetland edge is
less disturbed; soil pits verify the edge. There are two man-made ponds on the property that
overflow towards the wetland.
Classification and Jefferson Critical Areas Requirements
According the Jefferson County Critical Areas map (verified by on-site findings) a Class I wetland
exists to the west and north of the structures on the Slagle property. This wetland is large, spreading
throughout Beaver Valley, and is connected to fish-bearing streams (Ludlow Creek and near the
headwaters of Chimacum Creek). This wetland along the valley bottom includes a significant wildlife
habitat movement corridor, has a forested class, and contains significant habit features such as
standing dead trees. Class I wetlands receive the highest protection and require a maximum of 75
feet buffer from the wetland edge (Low Intensity Land Uses Jefferson County Critical Areas
Ordinance 6.505-5).
Buffer averaging (Subsection 6.508, with the criteria of Subsection 11.1002, Jefferson Critical Areas
Ordinance) will be an option only when the wetland functional values are not compromised. The
total area contained within the wetland buffer should be equal to or greater than the buffer sacrificed.
The standard buffer width cannot be reduced by more than fifty percent. A Class I wetland buffer
shall under no circumstances be less than 38' wide.
It should be noted that the boundary flagged represents only a small portion of this wetland, which
continues to the south and to the north and extends well beyond the subject property.
Soils
Soils EvD Everett gravelly sandy loam and Mm McMurray and Mukilteo Peat. McMurray and
Mukilteo Peat are soils are listed on the Jefferson County Hydric Soils List.
Test pits were dug to a depth of 16 inches in the wetland area and inspected for hydric conditions.
Highly saturated soils were located at Data Points #1, #3, and #6 and at Soil Test Pit #4. Top layers
of deep brown (10YR 3/1), gleyed (bluish gray) colored soil (5/10Y), and orange mottling were
observed in the wetland soil pits. All soil colors identified meet the requirements of hydric soil. An
upland test pit was dug to a depth of 16 inches; soil colors did not qualify as hydric (10YR 3/4 with
mottles).
Corp of Engineer Data forms for all Data Points are included in the Appendix.

•
Vegetation
Vegetation in the wetland areas includes a mixed deciduous tree layer of alder and two species of willows
with an understory of salmonberry, cattail, sedges, water parsley, nettles and buttercups. Several of these
species require regular inundation. Reed canarygrass, a non-native and often invasive grass, is present
along the wetland edge. The upland area is mostly cleared to accommodate the living areas.
Hydrology
There is a flowing stream, Ludlow Creek, at the bottom of the valley with areas of pooled water in
the adjacent wetland. Soil saturation and surface saturation were prevalent for 160 feet from the
creek. All of the wetland test pits had water within 3" to 10" of the surface.
Recommendations
Buffer averaging should include a buffer enhancement plan which specifies the introduction of native
trees and shrubs to increase the diversity and functional attributes of the buffer. The control of the
reed canarygrass, and removal of debris from the wetland (metal roofing, lumber piles, debris) is also
recommended. Any planting should be monitored at least 5 years to ensure success.
Summary
A Class I wetland is present on the Slagle property and buildings will be regulated according to the
Critical Areas Ordinance concerning wetlands. Buffers for Class I wetland are 75 feet. Reduction of
buffers is possible but shall be allowed only when specified criteria are met.
Final authority over this wetland determination and classification rests with Jefferson County and the
Corps of Engineers.
If you have any questions please feel free to call.
