INTRODUCTION
Ecological Land Services, Inc. (ELS)was contracted by Tim Wilkins to prepare this restoration
plan for the Gybe Ho Road property in the Nordland area of Jefferson County, Washington.This
property is comprised of parcel number 921092007 within Section 9, Township 29 North, and
Range 1 East of the Willamette Meridian (Figure 1).The restoration plan is required to rectify
disturbances to the onsite wetland per the violation order issued by the Washington Department
of Ecology in June 2015 (Ecology).
PROJECT DESCRIPTION
The wetland on this property was impacted by clearing, grading, filling, and dredging during
installation of a driveway onto the property in the spring of 2015.Development of the property
was proposed and the driveway was constructed across the wetland to provide access into the
interior of the property. The easement to the property lies at the west end but because there was
an easily identified wetland at the west end and there was an existing road from the east,the
driveway was constructed across the east end of the property. Portions of the site were cleared in
preparation of the development including the depressional forested wetland tha t lies across the
east half of the property. The driveway was constructed across the wetland and left an area of
undisturbed forest to the north. A culvert was placed beneath the driveway to allow continued
flow of water through the wetland area. The area of wetland immediately south of the driveway
was cleared and dredged. The spoils were spread across cleared wetland east and west of the
dredged area. Undisturbed wetland remains south of the cleared and dredged sections of
wetland.
Restoration of the wetland is proposed to restore the vegetation and function of the wetland that
was disturbed during the onsite construction activities. The restoration will include removal of
the driveway and the culvert. The gravel and fill material will be used to construct a new
driveway into the property, which will be located outside of the on and offsite wetlands.
Following removal of the driveway, the spoils will be placed back into the dredged and driveway
sections of the disturbed wetland. A bulldozer will be used to place the spoils into the dredged
area to the elevation of the undisturbed wetland areas north and south of the disturbance. Once
the dredged area is filled in,woody mulch chipped from onsite logging piles will be spread
across the graded wetland area. Large woody debris from the logging piles in the form of
horizontal logs and root wads will be placed in the wetland. Following grading activities,the
wetland and buffer areas will be planted with native trees and shrubs to restore the cleared
forested vegetation (Figures 3 and 4). Emergent and herbaceous vegetation will not be planted
because the seed sources remain within the dredge spoils and the original understory vegetation
will recover naturally.
Because the construction activities have resulted in at least three different impact categories,
each area will require special restoration activities. The disturbed area of wetland was cleared in
its entirety but not all of the wetland was dredged or filled.The multiple impacts have been
identified and the areas of impact identified are summarized in Table 1.

SITE DESCRIPTION
The property is located at the end of Gybe Ho Road in the Nordland area of Jefferson County
(Figure 1). Gybe Ho Road runs east of State Highway 116 just after it enters Marrowstone
Island. The property is located at the north end of a gravel drive that leaves the end of Gybe Ho
Road. It is rectangular in shape and is oriented east to west (Figure 1). The topography is
undulating to flat with a shallow linear trough oriented north to south across the eas t end of the
property. It is currently undeveloped but portions of the east half were recently cleared and a
driveway was constructed about midway across the east half (Figure 2). Soil logs have been
conducted by a septic system designer to prepare a septic system site plan for future
development. A fence is proposed just inside the perimeter of the property (Figure 2). The fence
and property lines have been staked around the entire property.
Wetlands
The delineated wetland is situated in the depressional trough across the east half of the property.
A 0.12-acre portion of the onsite wetland has been disturbed by clearing,construction of the
driveway, dredging of the south half of the wetland, and spread of dredge spoils. Undisturbed
forested wetland remains north and south of the disturbed area and represents the historic
condition of the disturbed wetland.The wetland begins just north of the disturbance and extends
south to Gybe Ho Road where it often floods the roadway. A small pipe was installed across the
road to facilitate drainage under the road and avoid flooding.
There are depressional wetlands offsite to the east (Offsite Wetland A) and west (Offsite
Wetland B). These wetlands extend just to the property line and do not continue onto th e
property so do not connect to the onsite wetland. There may be some overland flow onto the
property from the wetland to the east but there is no continuous wetland across the property line

and into the onsite wetland. Although the wetlands do not extend onto the property, the buffers
required from each will extend onto the east and west ends of the property.
The onsite wetland was delineated in June 2015 in accordance with Jefferson County Code
(JCC) Chapter 18.22, Article VI Wetland. The offsite wetlands were identified but not
delineated. The Wetland Delineation Report for the Gybe Ho Property Nordland, Washington
(ELS 2015) describes the 2015 methodology, collected data, and wetland categorization.Table 2
below summarizes the details of the on and offsite wetlands.

ASSESSMENT OF IMPACTS IN THE DISTURBED AREAS
Much of the north half of the wetland was impacted during site preparati on activities that
included construction of a driveway for access to the property. Clearing was undertaken prior to
installation of the driveway and involved removal of forested vegetation from a portion of the
onsite wetland and required buffer. The portions of the wetland along the north and south
property lines were not cleared and represent the conditions of the disturbed wetland (ELS
2015). Piles of cleared vegetation remain in portions of the wetland and buffer (Photoplates 2
and 3). The driveway was constructed across the north edge of the cleared wetland and a culvert
was installed under the driveway to allow continued water flow. The remainder of the cleared
wetland was then dredged from the south end of the culvert (outfall) and extended to the limits of
the clearing.The removed plant species included red alder (Alnus rubra), salmonberry (Rubus
spectabilis),slough sedge (Carex obnupta),lady fern (Athyrium filix-femina), and water parsley
(Oenanthe sarmentosa). During the 2015 site visits, these species were beginning to recover
where the dredge spoils were spread.
The clearing, dredging, and filling of the wetland has disrupted the onsite functions and impacted
the connectivity of the wetland to downstream systems. The water quality function was
significantly disturbed by clearing, which removed all of the vegetation layers and caused this
area of the wetland to no longer function to improve water quality. The dredging of soil material
from the wetland further disrupted this function and decreased the water quality of downstream
areas. The hydrologic functions were not significantly reduced but the method of water storage
Gybe Ho Road Property Ecological Land Services, Inc.
Draft Wetland and Buffer Restoration Plan December 2015

was altered. The wetland previously performed hydrologic functions by storage of water in the
organic soil profile and in small depressions formed in the terrain. By dredging the wetland, the
function was altered to an above-ground storage situation. The general habitat functions and
connectivity to other habitats were disturbed when the wetland was cleared, which was further
disrupted by the dredging and filling activities. Presently, the open water and filled sections of
the wetland are providing a different set of habitat components. This change in habitat
components may not have reduced the habitat provided by this wetland but it drastically changed
it from its original functions.Wetland impacts are summarized in Table 1 in the Project
Description section above.
RESTORATION APPROACH AND DESIGN
The restoration plan has been designed in accordance with requirements of the Washington State
Wetland Mitigation Guidelines, Volumes 1 and 2 (Ecology 2006). The general approach to the
restoration is to replace the soils that were removed from the wetland and to replace lost
vegetation. The goal is to initiate a trend to a forested vegetation community similar to what was
cleared for the site activities. The plan describes the steps necessary to restore all of the impacts
that have occurred to the onsite portion of wetland.
Restoration Sequencing
The impacts of the onsite disturbed wetland require that the restoration activities be conducted in
a specific order to ensure full restoration of the lost wetland functions.The restoration activities
will include:
Remove the driveway and culvert from the north end of the disturbed wetland. The
material from the driveway will be stockpiled outside the wetland and undisturbed buffer
for use in construction of the new driveway onto the property.
Scrape dredge spoils from the filled wetland areas and place into dredged wet land area.
Upland soils may be inadvertently included within the dredge spoils and will not be
considered wetland fill. The minor amounts of upland soil will aid in ensuring the spoils
are placed so that pre-disturbed elevations are achieved.
Place some of the large woody debris in the restored wetland and buffer from the piles
that remain within the wetland and buffer. The large woody debris placed will mostly
include larger logs and root wads. The remainder of the woody debris will be removed
from the wetland and buffer areas and disposed of at an appropriate location.However, it
may be used as woody mulch that will be placed over the graded surface.
Plant the disturbed wetland and buffer areas with native trees and shrubs to restore the
lost forested community. The herbaceous layer will not be planted as part of the
restoration plan because herbaceous and emergent plants are expected to recover
naturally due significant seed sources in the dredge spoils.
Restoration Strategy
The goal of the restoration is to restore the functions of the disturbed portion of the onsite
wetland area.The proposed restoration will provide no net loss of wetland area and wetland
functions.Restoration activities will require use of heavy equipment to fully remove the fill
(dredge spoils and driveway) from the disturbed wetland area and to return the spoils to the

dredged wetland. Grading activities will take place during the summer months to take advantage
of low water levels. All restoration activities will be fully supervised by the project biologist to
ensure the wetland is restored to pre-disturbed conditions.

Gallon species will be purchased from a native plant nursery.
Plants will have well-developed roots and sturdy stems, with an appropriate root -to-shoot
ratio.
All stock must be kept cool and moist prior to installation.
The project biologist will be responsible for inspecting the stock prior to and during planting;
unacceptable plant materials will not be planted.
Table 3 provides a draft native plant list for the restoration area. Plants specified for
restoration are species that are currently growing in the undisturbed area of the onsite wetland.
Shrubs will be installed in clumps of 5 to 6 throughout the wetland at a rough spacing of 5 feet
on center. Trees will be installed individually throughout the disturbed wetland at rough spacing
of 10 feet on center. Plants will be installed in the disturbed buffer areas and will include species
that are currently growing within the upland portion of the property. Plants will be installed
following grading activities to fill in the dredged portion during the late fall to early spring when
the site conditions are wettest and the plants are dormant.

GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS
Restoration Goal
The goal of restoration is to restore the disturbed wetland and buffer areas to pre-disturbance
conditions.
Objectives and Performance Standards
The following objectives and performance standards will ensure that the restoration goal is
achieved.
Objective 1. Restore pre-impact forested and scrub-shrub conditions throughout the
disturbed wetland and buffer areas.
Performance Standard #1a Restore wetland to pre-disturbance conditions.
Remove driveway to native soil and culvert from the wetland crossing.
Scrape the dredge spoils to native soil from the filled areas of wetland and
place back into dredged area of wetland.
Spread large woody debris in wetland from piles in the wetland following
replacement of the dredge spoils.
Objective #2:Install native trees and shrubs within disturbed wetland and buffer areas to
restore the cleared forested wetland system.
Performance Standard #2a Plant Survival
Years 1-2 100 percent survival of all plants including tree, shrub, and
emergent species.
Years 3-5 If survival rate met in Years 1 and 2, no additional survival
rate monitoring shall be conducted.
Performance Standard #2b Vegetation Cover
Yearly percent coverage standards are proposed for the tree and shrub species
proposed within the restored wetland and buffer areas. The following yearly
standards are proposed for the tree and shrub layers.
Year 1:10-15 percent cover by installed/volunteer native woody plants.
Year 2:15-20 percent cover by installed/volunteer native woody plants.
Year 3:20-25 percent cover by installed/volunteer native woody plants.
Year 5:35-40 percent cover by installed/volunteer native woody plants.
Performance Standard #2c Emergent Understory Coverage
The emergent cover within the restored wetland is expected to recover
naturally due to the seed sources remaining within the dredge spoils. For this
reason, it is expected that coverage by emergent will expand yearly but at a
different rate than the trees and shrubs, therefore, the yearly standards are
slightly less than for the woody plants.
Year 1:minimum 10 percent cover.
Year 2:minimum 15 percent cover.
Year 3:minimum 20 percent cover.
Year 5:minimum 25 percent cover.
Gybe Ho Road Property Ecological Land Services, Inc.
Draft Wetland and Buffer Restoration Plan December 2015

Objective #3:Maintain Low Cover by Non-Native Invasives. Restoration plans often
experience inputs of non-native plant species via seeds deposited by birds or
swept in by wind. Low coverage by invasive plants is proposed to allow
native plants to become prevalent within the wetland and buffer areas.
Performance Standard #3a Non-Native Invasives Plant Coverage
Years 1 to 5: Less than 10 percent cover by non-native exotics including but
not limited to reed canarygrass, evergreen or Himalayan blackberry, and
Scot’s broom.
Objective #4:Maintain the Original Boundary of Wetland A by the end of the 5-year
monitoring period.
Performance Standard #4a Original Wetland Boundary
Year 1 and Year 3: Conduct delineation and survey of Wetland A during
Year 1 and Year 5 monitoring visits to ensure that there have been no changes
to the original wetland area.
MONITORING PLAN
The restoration area will be monitored once during the mid to late growing season for a 5-year
period following plant installation.The goal of monitoring is to determine if the performance
standards are being met.Monitoring will occur in Years 1, 2, 3, and 5,and monitoring reports
will be submitted to Jefferson County and Ecology by December 31st of the monitored year.
Three to four individual monitoring plots marked with labeled steel posts will be established to
assess native plant survival and cover throughout the restored wetland and buffer.Additionally,
up to 6 photo stations will be established throughout the restoration area including one at each
monitoring plot.
Vegetation
Emergent/Herbaceous
Monitoring will document the natural recovery of the herbaceous plant layer using percent cover
methodology within the designated monitoring plots. The following information will be
included at each plot:
Percent cover of herbaceous species (10-foot by 10-foot plot)
General health of plants in the monitoring plot, noting specific problems and potential
causes
Photo documentation of vegetative changes
Scrub-shrub and Forested
Monitoring will document the survival and percent cover of trees and shrubs within the
designated planting areas. The following information will be included at each plot:
Percent survival (Years 1 and 2)
Percent cover of scrub-shrub and tree species
General health of plants in the monitoring plot, noting specific problems and potential
causes

MAINTENANCE
Maintenance in the restoration areas will include watering as necessary during growing season in
the first three years of monitoring and hand clearing or weed eating competitive grasses from
bases of planted trees and shrubs as needed during the growing season.
If the planting area is failing, steps will be taken to rectify the situation in a timely manner. The
following steps will be implemented when an area is identified as failing or po tentially failing:
Identify the cause(s) of the failure or potential failure
Identify the extent of the failure or potential failure
Implement corrective actions such as irrigating, fertilizing, and replanting
Document the activities and include this data in the annual monitoring and maintenance
reports
In the event that a routine corrective action will not correct the problem, immediately
consult with the appropriate agencies
Evaluate recommendations from resource agency staff and implement recommendations
in a timely manner
CONTINGENCY PLAN
If the performance standards are not met by the third year following plant installation, a
contingency plan will be developed and implemented. All contingency actions will be
undertaken only after consulting and gaining approval from Ecology and Jefferson County. The
applicant will be required to complete a contingency plan that describes: 1) the causes of failure,
2) proposed corrective actions, 3) a schedule for completing corrective actions, and 4) whether
additional maintenance and monitoring are necessary.

Photo 1 is taken from the north
end of the property on Gybe Ho
Road. It looks southwesterly
from the start of the driveway
constructed earlier this year. The
photo shows the south half of the
disturbed wetland and buffer area
for which the restoration plan has
been prepared.Some of the
spoils removed from the wetland
were placed in this location. The
restoration plan proposes to
replace the spoils and replant.
Photo 3 is taken from the same
location as Photos 1 and 2. It
looks northwesterly toward the
undisturbed forested wetland
area immediately north of the
impacted wetland and buffer
area.Spoils from the dredging
were placed in this location and
will be spread back into the
wetland as part of the
restoration plan.
Photo 2 is taken from the same
location as Photo 1 and looks north
along the trail. The area beyond
the maple tree on the right is a
historic clearing that is now
dominated by blackberry thickets.
Photo 2 is taken from the same
location as Photo 1. It looks
westerly along the driveway
with the disturbed wetland and
buffer areas to the right and
left.The driveway will be
removed as part of the
restoration plan. It will be
moved to another location
around the onsite and offsite
wetlands.

Photo 4 was taken on May 15,
2015 from the driveway at the
culvert installed to allow water
flow from one side to the other.
The area shown is primarily
wetland that was dredged during
construction of the driveway.
The wetland extends up the slope
on both sides of the created
drainage.Spoils removed from
the dredged area were spread on
both sides of the new channel.
Photo 6 is taken on the same
day and from the same location
as Photo 5. It looks across the
disturbed area of wetland west
of the drainage channel
pictured in Photos 4 and 5.
The dredge spoils were spread
across this area of wetland so
represents wetland fill.The
restoration proposes to replace
the spoils.
Photo 2 is taken from the same
location as Photo 1 and looks north
along the trail. The area beyond
the maple tree on the right is a
historic clearing that is now
dominated by blackberry thickets.
Photo 5 is taken on June 15,
2015 from the same location as
Photo 4. Water is no longer
present in the drainage except
in a very small portion in the
shady portion of the photo.

Photo 10 was taken during the
June 15, 2015 field visit from the
edge of the undisturbed wetland
north of the driveway. It looks
south across the driveway and
shows much of the disturbed
wetland area for which
restoration is proposed. The
areas shown in this photo will be
restored by replacing spoils and
planting with native vegetation.
Photo 12 is taken from the
same location as Photo 11. It
looks northeasterly toward the
undisturbed wetland area. The
area in the foreground is
disturbed by clearing and
filling.Photo 2 is taken from the same
location as Photo 1 and looks north
along the trail. The area beyond
the maple tree on the right is a
historic clearing that is now
dominated by blackberry thickets.
Photo 11 is taken from the
driveway at the culvert
crossing. It looks north into
the narrow disturbed area
between the driveway and the
undisturbed forest. The pile of
large woody debris in this
photo will be placed in the
restored wetland following
replacement of spoils and prior
to plant installation.Smaller
parts may be chipped into
woody mulch and spread over
the restored wetland.

same location as Photos 11 and
12 (Photoplate 3). It looks down
into the section of disturbed
wetland on the north side of the
culvert.
Photo 15 is taken of the
disturbed buffer area west of
the wetland and north of the
unpermitted driveway. This
area will be replanted with
native trees to recover buffer
vegetation. Shrub and
herbaceous layers will recover
naturally because remnant
vegetation is present
throughout.

location as Photo 1 and looks north
along the trail. The area beyond
the maple tree on the right is a
historic clearing that is now
dominated by blackberry thickets.

driveway at the culvert
crossing.It looks southeasterly
into the disturbed wetland and
buffer area south of the
driveway and east of the
dredged channel.
