Wetland Mitigation Plan i March 17, 2022
EXECUTIVE SUMMARY
On behalf of Josiah Brown, Ecological Land Services, Inc. (ELS) has prepared a mitigation plan
report for the unavoidable impacts to Wetland A needed to access the building site on property at
413 Gybe Ho Road, Jefferson County Tax Parcel 921092007, in Nordland, Washington. This
property is 5.13 acres in size and is currently undeveloped. It is within Section 9, Township 29
North, Range 1 West of the Willamette Meridian. This mitigation plan was prepared according
to the Jefferson County Code, Title 18 Unified Development Code (UDC), Section 18.22 Critical
Areas Article VII Wetlands (JCC) and the Washington State Department of Ecology guidance
Wetland Mitigation in Washington State (2006).
Four wetlands were identified and delineated on or near this property by ELS in 2016 and 2021
for purposes of determining the buffers for placement of a single family home and drainfield.
The delineation was also conducted to determine access to the building site. The legal easement
enters the southwest corner from Gybe Ho Road. However, there is a Category III wetland
(Wetland B) at the north end of the easement and would require significant impacts if a driveway
was constructed in the easement (Sheet 2). An alternative driveway access was required to avoid
and minimize impacts. Wetland A was delineated along the east property line in 2016 for the
previous owner who had placed a driveway across the wetland without permits and was required
to remove the driveway to restore wetland conditions. This wetland was also cleared and
excavated by the previous owner and is undergoing natural restoration and is currently
dominated by pioneer emergent species. Portions of the buffer were also cleared and are
currently being planted with conifer trees to restore forested conditions. The driveway is
accessed by an existing dirt road that also accesses properties to the east so there is an existing
access from Gybe Ho Road and impacts are avoided. Wetland A has not fully restored from the
previous impacts so constructing the driveway across this wetland will be the least impactful to
the onsite critical areas and buffers. The project is minimizing impacts by crossing at the
previous location where there is no significant vegetation coverage and the wetland is narrowest.
The total area of wetland impact is 285 square feet and the buffer impact is 3,016 square feet.
Mitigation will include 570 square feet of wetland creation adjacent to Wetland A and 5,600
square feet of buffer mitigation (Sheet 4).
Mitigation Goals and Objectives
Goal 1: Create 570 square feet of wetland to compensate for the fill of 285 square feet of
Wetland A.
Objective 1a. Excavate upland 570 square feet adjacent to Wetland A and alongside
the driveway to the elevation of the existing wetland.
Objective 1b: Install native shrub cuttings to establish scrub-shrub vegetation
community.
Objective 1c: Maintain a seasonally flooded hydroperiod with 2 to 6 inches of
standing water during the growing season in the new wetland area that matches the
hydroperiod of the existing wetland.

Wetland Mitigation Plan ii March 17, 2022
Goal 2: Plant native trees within the buffer to compensate for the driveway buffer
impacts.
Objective 2a. Native shrub and herbaceous plant recovery is ongoing naturally and
trees are being planted currently. Additional trees will be installed around the
existing vegetation to continue the ongoing restoration plantings.
Goal 3: Protect wetland functions
Objective 3a. Permanently demarcate the wetland buffer boundary.
Objective 3b. Provide long-term legally binding protection.
The mitigation site will be monitored for a 5-year period following project construction.
Monitoring will take place in Years 1 through 5. The goal of monitoring is to determine if the
mitigation performance standards are being met. The mitigation area will be monitored once
during the growing season, preferably during the same two-week period each year to better
compare the data. Hydrologic monitoring will be conducted during the early growing season of
each monitoring year to ensure that the created wetland hydrology matches the existing wetland
hydrology. Monitoring will begin at the end of the first summer following full implementation
of the mitigation plan.

PROJECT DESCRIPTION
PROJECT LOCATION
The single family home and driveway are proposed on the property located at 413 Gybe Ho Road,
Jefferson County Tax Parcel No. 9219092007, in Section 9, Township 29 North, Range 1 West of
the Willamette Meridian in Nordland, Washington (Sheet 1). This property is within Water
Resource Inventory Area (WRIA) 17 Quilcene-Snow and the 12 digit Hydraulic Unit Code (HUC)
171100190803 – Marrowstone Island-Frontal Port Townsend.
SITE CONDITIONS
Development Site
The property is located at the end of Gybe Ho Road in the Nordland area of Jefferson County
(Sheet 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 (Sheet 1). The topography is undulating to flat
with a shallow linear trough-oriented north to south across the east end of the property. It is
currently undeveloped, but portions of the east half were previously cleared (Sheet 2). Soil logs
have been conducted by a septic system designer to prepare a septic system site plan for future
development.
Three wetlands were delineated onsite and one offsite. Wetland A was previously delineated by
ELS and is situated in the depressional trough across the east half of the property. A large portion
of the wetland had been previously disturbed by construction of a driveway, dredging of the south
half, and spread of dredge spoils in the buffer. The previous owner did not complete restoration,
but the driveway and culvert were removed, and current owners are planting native trees to meet
restoration requirements. Forested wetland remains north and south and represents the historic
condition of the disturbed wetland. Wetland A is a forested depressional system with a seasonally
flooded hydroperiod. Wetland B was delineated offsite and is situated in a depressional trough
southwest of the property. This wetland is present in the legal easement to the property, which
enters the southwest corner of the property. Wetland B is a forested depressional system with a
seasonally flooded hydroperiod. Wetland C was identified and delineated onsite near the western
property line, just north of Wetland B. Wetland C extends offsite to the west and is a forested
sloping system with a saturated only hydroperiod. Wetland D was identified and delineated onsite
near the northern property line, northwest of Wetland A. Most of wetland D extends offsite to the
north. Wetland D is a forested depressional system with a seasonally flooded hydroperiod. The
HGM, category, habitat score and required buffer widths are presented in Table 2.
The remainder of the site is composed of upland forest with a dense shrub understory. In some
areas, wetland plant species and wetland hydrologic indicators were observed, but these areas are
upland because they lack positive indicators for hydric soils. These areas appear to be old logging
roads where surface water collects for short periods during the winter.

Mitigation Site
Mitigation for the driveway impacts will take place onsite and adjacent to the same wetland as the
impact. The east boundary of Wetland A is crenulated with peaks extending easterly where the
wetland and buffer were impacted during previous land clearing activities. The mitigation site was
selected to facilitate creation of wetland along a narrow section of the wetland and adjacent to an
easterly point in order to ensure that sufficient hydrology is provided. It will be located just north
of the driveway so that excavation can occur from the driveway after it is constructed to avoid
additional impacts to the wetland and buffer.
The mitigation site is currently dominated by dense soft rush (Juncus effusus, FACW) with a few
trees that were planted as part of the restoration plan (Photoplate 1). The wetland area is
seasonally flooded with water and the source includes a seasonally perched water, surface water
runoff, and direct precipitation. The sources of hydrology appear to be sufficient to support a
small additional area of wetland.
PROJECT DESCRIPTION AND PROPOSED IMPACTS
The project proposes a single family home near the middle of the property, which is a formerly
logged upland area that is composed of pioneer plant species. The location of the home was
selected because it is outside the buffers of the four wetlands that were identified on and offsite.
However, the position of the wetlands does not allow access to the building site without crossing
one of the wetlands. Wetland A was previously impacted by a driveway crossing and remains
somewhat disturbed so represents the most logical location for the required driveway (Photoplate
1). The approach to the property is existing and lies within the buffer. The new driveway will
cross through half of the buffer on the east side and the entire 110 foot buffer on the west side; the
total area of buffer impact is 3,016 square feet. The driveway will cross the narrowest portion of
the wetland for a total of 285 square feet. Mitigation is proposed to compensate for the wetland
and buffer impacts by creating 570 square feet of new wetland alongside Wetland A and 5,600
square feet of buffer enhancement on the west side. The buffer mitigation will supplement the
ongoing restoration by planting native conifer trees and proposes mitigation area and will include
removal of invasive plant species followed by installation of native trees and shrubs.

Wetland Mitigation Plan 3 March 17, 2022
The overall goals of the proposed mitigation are to:
1) Achieve no net loss of wetland function by creating two times more wetland adjacent to
Wetland A.
2) Enhance the western buffer of Wetland A through additional plant installation.
WETLAND DELINEATION AND CATEGORIZATION
ELS completed a wetland delineation and categorization in 2021 for Josiah Brown (ELS 2021).
Additionally, areas of the property that had been logged were determined to be non-wetland
despite the dominance by wetland plant species because of the lack of hydric soil and wetland
hydrology indicators. The wetland delineation and determination was confirmed during a field
visit with Rebecca Rothwell of the Washington Department of Ecology (Ecology) and Donna
Frostholm of the Jefferson County Department of Community Development (JCDCD) on July 14,
2021. The wetland boundary was altered slightly in one area but overall was determined to be
accurately delineated. The logged areas dominated by wetland vegetation were confirmed to be
non-wetland through additional soil observations by Ecology and JCDCD.
Wetland Categorization
The wetlands were categorized according to functions using the Washington State Wetlands Rating
System for Western Washington, 2014 Update (Rating System) (ELS 2021). Table 2 summarizes
the ratings.

WETLAND FUNCTIONS ASSESSMENT
IMPACT AREA-WETLAND A
Wetland A is located on the east end of this property beginning at the north end and extending
south to Gybe Ho Road (ELS 2021). Most of this wetland was impacted in 2015 by the previous
owner who excavated the onsite portion, installed a culvert, and constructed a road used to log the
property. Prior to the impact, the wetland was a forested system similar to the area offsite to the

south and is currently composed of an emergent community dominated by soft rush. The wetland
was rated based on the forested, forested w/3 layers vegetation community that was present prior
to the disturbances that created the emergent community. The emergent community does not
increase the overall value for any of the functions despite covering more than 10 percent of the
wetland unit.

POST IMPACT AND MITIGATION WETLAND FUNCTIONS
The mitigation plan proposes to replace the functions potentially lost as a result of driveway
construction but the functional values of Wetland A will not increase as a result of this mitigation
because it proposes a very small area of wetland as compensation, which will not increase the size
of the wetland significantly. Although it will be planted with shrub species, the created wetland
will not produce an increase in habitat function because the scrub-shrub area will be small in
DCD RECEIVED 5/12/2022

Wetland Mitigation Plan 5 March 17, 2022
relationship to the current forest and emergent vegetation communities (i.e. the new scrub-shrub
area will not provide a significant increase in the interspersion of habitats). Therefore, the
functional values of Wetland A will be the same pre and post driveway construction.
MITIGATION APPROACH
This mitigation plan is being prepared to compensate for creation of a driveway across the onsite
portion of Wetland A, which will impact 285 square feet (0.0065 acres) of the previously disturbed
area. The crossing location was selected because it is the narrowest point of the wetland and the
vegetation remains dominated by emergent species. The project requires permittee-responsible
mitigation because there are no mitigation banks available in Jefferson County. There is an in-lieu
fee program within Hood Canal but this property is outside the service area. Mitigation is
proposed alongside Wetland A and immediately adjacent to the impact (Sheet 4).
MITIGATION SEQUENCING
The wetland mitigation requirements of the local, state, and federal agencies specifies that all
regulated development activities proposing permanent impact wetlands or buffers shall examine
whether the impacts can be avoided and/or minimized prior to proposing compensation for the
impacts.
Avoiding Wetland Impacts. The property is 5 acres in size and about half is composed of
wetlands and buffers that occur along the property lines. The legal easement to the property was
established to the southwest corner but there is an undisturbed wetland (Wetland B) at the north
end of the easement (Sheet 4). Use of this easement would impose significant impacts to that
wetland so an alternative access was necessary. The driveway at the east end of the property
accesses two other properties and had been installed to this property one of the adjacent land
owners. Wetland A spans most of the east end of the property with upland at the north end. This
area of upland represents the northern wetland buffer and because it is composed of a relatively
undisturbed, placing the driveway around the north end of the wetland would result in removal of
forested vegetation. Therefore, the driveway is proposed across the narrowest portion of Wetland
A (Sheet 4). This project has examined all potential alternatives to the driveway across Wetland A
but none were found that would have less impact to the onsite wetlands and buffers. Therefore,
this project cannot avoid the proposed wetland impacts.
Minimizing Wetland Impacts. The driveway will be constructed across the narrow portion of
Wetland A where it is dominated by emergent vegetation that volunteered in the wetland following
the previous impact. The project minimizes impacts to the onsite wetlands and buffers by:
Crossing the wetland at the narrowest point to reduce the area of wetland fill.
Crossing Wetland A and buffers in the previously impacted location.
The crossing location is dominated by herbaceous and emergent pioneer species and will
not require removal of native woody plants.
The mitigation location was selected in order to further minimize impacts by constructing
the driveway before creating the additional wetland.
Completing construction in the dry to avoid impacts to water quality and quantity.

Wetland Mitigation Plan 6 March 17, 2022
Mitigation Options in Order of Preference:
Rectifying the Impact by reestablishing, rehabilitating, or restoring the affected environment.
The wetland will be permanently impacted to create the driveway so mitigation will not involve
reestablishing, rehabilitating, or restoring the affected environment.
Compensating for the Wetland Impact by Replacing or Providing Substitute Resources or
Environments-Although the project is able to minimize impacts to Wetland A, it cannot avoid the
direct impact that will be caused by the proposed driveway. Therefore, this project proposes to fill
285 square feet of Wetland A and impact 3,016 square feet of the buffer on both sides to construct
the driveway from the east property line to the proposed building site. Wetland creation is
proposed at a 2:1 ratio, which is in accordance with mitigation requirements, so a total of 570
square feet of wetland will be created next to Wetland A (Sheet 4). Shrub cuttings are proposed
for installation within the created wetland area (Sheet 5). Buffer mitigation is proposed at ratio of
1.85:1 to compensate for the impact to the buffer of Wetland A and will consist of plant
installation in conjunction with the ongoing restoration activities. The buffer enhancement area is
5,600 square feet in area and is proposed on the east side of Wetland A.
Monitoring the Impact and Compensation and Taking Appropriate Corrective Measures
Monitoring of the wetland mitigation area for this project is proposed for a period of 5 years to
document the improvement of wetland and buffer conditions within the mitigation area.
Hydrology monitoring is proposed in the early growing season to ensure the appropriate
hydroperiod is created within the new wetland area and vegetation monitoring will take place in
the late summer/early fall to determine the success of the plants installed within the wetland and
buffer.
MITIGATION RATIOS
The Wetland Mitigation in Washington State, Volume 1, Agency Policy and Guidelines (2006),
compiled by the WDOE, the USACE, the US Environmental Protection Agency and the PMC,
specifies several ratios for mitigation of impacts to Category IV wetlands. The Category IV
wetland mitigation ratios include:

WETLAND MITIGATION GOALS
The main goal of the mitigation plan is to compensate for the fill of 285 square feet of Wetland A,
which is a Category III depressional wetland to construct the driveway necessary to access the
proposed building site. The general goals of this mitigation include:
Goal #1 Create 570 square feet (0.013 acres) of depressional, scrub-shrub wetland
adjacent to Wetland A. Emulate the hydroperiod of the existing wetland in
the created wetland area.
Goal #2 Enhance 5,600 square feet (0.128 acres) of the eastern buffer of Wetland A
as compensation for the impacts to the eastern and western buffers.
Goal #3 Increase the diversity and function of the wetland and buffer of Wetland A
by planting shrub cuttings within the created wetland to create a scrub-shrub
vegetation community.
PERFORMANCE STANDARDS
The performance standards have been developed to monitor the success with respect to the goals
and objectives of this mitigation plan, which relate directly to improving wetland functions and
development of the desired vegetation community. The following objectives and performance
standards have been developed for this wetland mitigation project:
Objective #1 Create additional seasonally flooded wetland adjacent to Wetland A to
compensate for direct impacts of driveway construction. Vegetation
enhancement is proposed for the created wetland as well as the western
buffer to replace vegetation lost through construction. The plants will also
improve plant species diversity and increase the function of the buffer.
Performance Standard #1a Seasonally flooded hydroperiod
Years 1 to 5: Maintain seasonally flooded hydroperiod between that is consistent
with the remainder of Wetland A of seasonal standing water 2 to 6 inches deep or
soil saturation within 12 inches of the soil surface between February 15th and April
1st of each monitoring year.
Performance Standard #1b Plant Survival
Year 1 and 2 100 percent survival of all plants including tree, shrub, and
emergent species.
Years 3 to 5 80 percent survival of all plants including tree, shrub, and
emergent species.
Performance Standard #1c Native Vegetation Cover
Yearly percent coverage standards are proposed for the tree and shrub species to be
installed within the created wetland and enhanced buffer areas. The following yearly
standards are proposed for the tree and shrub layers.
Year 1: 15-20 percent cover by installed/volunteer native woody plants.
Year 2: 20-30 percent cover by installed/volunteer native woody plants.
Year 3: 30-40 percent cover by installed/volunteer native woody plants.
Year 4: 40-50 percent cover by installed/volunteer native woody plants.
Year 5: 50-60 percent cover by installed/volunteer native woody plants.

Wetland Mitigation Plan 8 March 17, 2022
Performance Standard #1c Plant Species Height and Diversity
Year 5 Created Wetland and Buffer: Minimum of 15 percent cover by at least
2 of the shrub species installed within the wetland that are at least 4 feet tall.
Objective #2 Maintain Low Cover by Non-Native Invasives
Mitigation projects are often subject to 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 #2a Non-Native Invasives Plant Coverage-Years 1 to 5: Less
than 15 percent cover by non-native exotics including but not limited to reed
canarygrass, Himalayan blackberry, and Scot’s broom.
WETLAND MITIGATION PLAN
The wetland mitigation plan proposes to create 570 square feet of wetland adjacent to Wetland A
and to enhance 5,600 square feet of buffer to compensate for the wetland and buffer impacts
resulting from driveway construction. Wetland creation will involve excavation of material from
the upland just west of Wetland A and north of the driveway to reach the elevation of the wetland.
The area will then be planted with native shrub species in the form of cuttings. Buffer
enhancement is proposed in conjunction with the required buffer restoration that has been ongoing
for several years. The buffer will be planted with native trees and shrubs around existing
vegetation and more recently installed conifer trees. The project biologist will supervise the
creation of the wetland to ensure that the appropriate elevations are reached and will be available
to assist with implementation of the planting plan.
GRADING PLAN
The small size and location of the proposed wetland creation did not warrant the creation of a
grading plan complete with contours and cross sections. Grading of the created wetland will be
conducted following construction of the driveway and placement of the culverts (to allow for
continuous water flow from north to south). The location was selected so that once the driveway is
constructed, an excavator can be staged on the driveway and reach into the mitigation area and
excavate the soil to the elevation of Wetland A. The project biologist shall be onsite during
excavation of the wetland to ensure the appropriate elevation is reached. Wetland A and the
immediate buffer areas are composed of deep silt loam soils with some organics mixed in and it is
unlikely that soil amendment will be needed. The need for soil amendment will be determined by
the project biologist during creation of the wetland.
All work within the wetland and buffer to construct the driveway and new wetland area will be
completed during the summer months when the wetland does not contain water and there is a
lower chance of heavy precipitation events. Woody mulch may be applied following construction
of the wetland to slow the recovery of invasive species and to retain moisture for the plants, if
needed. As built mapping will be conducted following construction to ensure the appropriate area
has been created and the appropriate elevations were achieved.

PLANTING PLAN
The mitigation planting plan proposes to establish a scrub-shrub community with in the created
wetland area (Sheet 5). The native volunteers that currently inhabit the wetland and buffer will be
allowed to grow naturally so no herbaceous or emergent plant installations are proposed. The
plants installed within the wetland mitigation area are listed in Table 6. The plants selected for
installation in the created wetland and buffer include species that can grow and thrive in saturated
soil conditions and somewhat dry conditions in the upland, respectively. Coniferous and
deciduous trees are proposed within the buffer to encourage development of a mixed forest
community to increase diversity in the buffer areas. Additional native species from the adjoining
wetland are expected to also inhabit the forest stratum of the wetland and buffer.
SPECIFICATIONS FOR PLANTING
The plants specified for the created wetland and buffer will diversify the existing plant community
and provide cover and wildlife habitat in both the short- and long-term.
Plant Materials
Bare-root or Potted Stock:
1. Bare-root or potted species will be purchased from a native plant nursery.
2. Bare-root or potted stock will be a minimum size of 18- to 36-inches tall.
3. Bare-root or potted stock will be kept cool and moist prior to being planted.
4. The bare-root stock will have well-developed roots and sturdy stems, with an appropriate root-
to-shoot ratio.
5. No damaged or desiccated roots or diseased plants will be accepted.
6. Unplanted bare-root or potted stock will be properly stored at the end of each planting day to
prevent desiccation.
7. The environmental consultant can be available either onsite or through submission of photos to
determine the appropriate plants have been obtained for the mitigation.
Cuttings:
1. Cuttings are proposed within the created wetland only because of the small size of the
wetland area and the seasonally flooded hydroperiod.
2. Cuttings shall be obtained from well-established pacific willow, red osier dogwood, and
black twinberry bushes immediately before the planned installation.
3. Collection shall be completed during the winter months when the sources are dormant.
4. Each cutting shall be at least 36 inches long and about 1/4 inch to 1/2 inch caliper.
5. The cut end of each cutting shall be pushed into the ground so that at least three nodes are
in the ground or between 6 and 8 inches.
Plants will be installed in the October through March when the site conditions are wettest and the
plants are dormant. Plants will be installed in mono-specific groups to mimic natural colonization
and enhance individual plant survival. Plantings will be spaced to allow for removal of invasive
species. The following table summarizes the plant species, spacing, size, and quantities for the
wetland and buffer mitigation areas (Tables 6 and 7).

Planting Specifications
1. Plant the specified trees and shrubs in the fall (October-November) or early spring (March-
April) at the spacing listed. The plants will be installed somewhat irregularly and in groups of
like species to create heterogeneity in the density and appearance of the mitigation areas, but
with enough space between each group to allow for maintenance of invasive species. Install
plants with a tree shovel or comparable tool.
2. Place the bare-root species in the planting holes so that their roots are able to extend down
entirely and do not bend upward or circle inside the hole.
3. Position the root crowns so that they are at or slightly above the level of the surrounding soil.
4. Push the cuttings into the wetland soil so that at least 3 nodes are below ground or between 6
and 8 inches.
5. Firmly compact the soil around the planted species to eliminate air spaces.
6. Install anti-herbivory devices, such as seedling protection tubes or mesh protection netting,
around the stems of planted species as appropriate. Secure with stakes.
7. Irrigate all newly installed plants as site and weather conditions warrant.
MITIGATION PLAN SCHEDULE
Planting of the mitigation area prior to construction activities could result in destruction of the
plants and mitigation area so planting is recommended during the first winter/spring season
following construction of the driveway. The following sequence is proposed for implementation
of the mitigation plan should the project begin construction activities within the next year.
DCD RECEIVED 5/12/2022
Josiah Brown – Gybe Ho Property Ecological Land Services, Inc.
Wetland Mitigation Plan 11 March 17, 2022
Grading Activities-July to September
o Identify the limits of the proposed mitigation area once the driveway has been
installed. Clearly mark the buffer edge with orange construction fencing or similar
fencing to demarcate the areas to remain undisturbed during construction activities.
o Clearly mark the extent of the wetland creation and assess the elevation of the
existing wetland to determine the initial approximate depth to which excavation will
occur.
o Project biologist to be onsite during excavation to ensure that the appropriate depths
are reached and determine if soil amendments are needed.
Planting Activities-October to March
o Plant installation will take place during the first winter after onsite construction is
completed to ensure that mitigation area is not impacted by ongoing work.
o Prepare as built report following full implementation of the mitigation plan to
document any changes to the clearing, grading, and/or planting activities.
MAINTENANCE
Maintenance of the mitigation area is a 5-year process and will involve removing persisting
invasive plant species in addition to watering, fertilizing, and re-installing failed native species as
necessary. Maintenance will include the following activities when necessary:
1. Remove and control non-native vegetation around all newly installed plants a minimum of
three times during the growing season in each of the monitoring years following
implementation in order to meet performance standards.
2. Irrigate planted species as necessary during the dry season, approximately July 1 through
October 15. ELS recommends watering the mitigation area at least every two weeks during
the dry season for the first year, and monthly in Years 2 and 3. Watering can be conducted
by hand or use of a common residential sprinkler connected to the closest hose bib.
3. Fertilize planted species as necessary.
4. Replace dead or failed plants as described for the original installation to meet the minimum
annual performance standards.
If the mitigation area is failing or the performance criteria are not met during monitoring years,
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 potentially failing:
1. Identify the cause(s) of the failure or potential failure.
2. Identify the extent of the failure or potential failure.
3. Implement corrective actions such as irrigating, fertilizing, and/or replanting.
4. Document the activities and include this data in the annual monitoring and maintenance
reports.
5. In the event that a routine corrective action will not correct the problem, immediately
consult with the appropriate agencies.
6. Evaluate recommendations from resource agency staff and implement recommendations in
a timely manner.

MONITORING PLAN
The wetland mitigation will be monitored annually for a 5-year period following project
construction. Monitoring will take place in Years 1 through 5. Monitoring reports will be
submitted to the Jefferson County Department of Community Development by December 31st of
each monitored year. The goal of monitoring is to determine if the previously stated performance
standards are being met. The mitigation area will be monitored once late in the growing season,
preferably during the same two-week period each year to better compare the data. Yearly water
level monitoring will take place in the early growing season within established locations in the
mitigation area.
During preparation of the as-built report, monitoring units will be selected in the mitigation areas
and permanently marked with metal posts. Three to four monitoring units will be established in the
created wetland and buffer areas. Monitoring unit locations will be indicated on the as-built
drawing and included in the annual monitoring reports. Baseline data and photos will be taken of
each monitoring unit to document as-built conditions for use in the follow-up monitoring reports.
HYDROLOGY
Hydrological monitoring is necessary to ensure that the appropriate hydroperiod is achieved within
the mitigation area. Because of the small size of the mitigation area, a single monitoring unit will
be established in the wetland where the weekly water level monitoring will also take place. Water
level monitoring will also take place on either side of the driveway to ensure that the placement of
the culverts are not changing the hydrology within all areas of the wetland.
Weekly measurements shall be taken during the period between February 15th and April 1st.
Surface water measurements to determine depth.
When surface water is absent, a hole will be dug in the wetland to a depth of 16 inches to
determine the depth of the shallow water table and/or the depth to soil saturation.
The water level monitoring results will be included in the end of growing season report along
with the vegetation monitoring results.
VEGETATION
Vegetative monitoring will document the development of the forested and shrub layers in the
created wetland and buffer. The following information will be included at each monitoring unit:
Percent cover and frequency of shrub species (20-foot radius)
Percent cover and frequency of any tree species (30-foot radius)
Species composition of herbs, shrubs, and trees, including native volunteers and non-native,
invasive species
Photo documentation of vegetative changes over time from established photo station.
FAUNA
General observations will be recorded and photographs will be taken of wildlife during site visits
to the mitigation areas. Observations of insects and other invertebrates, amphibians, reptiles, birds,
and mammals will be recorded and documented in the annual monitoring reports. Use of the onsite
mitigation area by any priority species will also be noted.

MONITORING REPORT CONTENTS
The annual monitoring reports will contain at least the following:
Location map and as-built drawing.
Historic description of project, including dates of plant installation, current year of
monitoring, and restatement of mitigation goals, objectives, and performance standards.
Description of monitoring methods for vegetation and hydrology monitoring.
Documentation of plant cover and overall development of the plant communities.
Assessment of non-native, invasive plant species and recommendations for management.
Assessment of buffer conditions, e.g. surrounding land use, use by humans, and use by wild
and domestic animals.
Observations of wildlife, including, amphibians, invertebrates, reptiles, birds, and mammals.
Photographs from permanent photo points and monitoring units.
Summary of maintenance and contingency measures proposed for the next season and
completed for the past season.
LONG TERM MANAGEMENT PLAN
The wetland and buffer mitigation area will be maintained over the five-year monitoring period to
keep the invasive cover low in order to establish the forested conditions in the mitigation area.
Buffer boundary signs will be posted to identify the critical area that requires protection.
CONTINGENCY PLAN
If the performance standards for the wetland mitigation plan are not met by the 5th year of
monitoring, a contingency plan will be developed and implemented. All contingency actions will
be undertaken only after consulting and gaining approval from the regulatory permitting agencies
that approved this plan. The contingency plan will describe (1) the causes of failure, (2) proposed
contingency actions (listed below), (3) time-frame for completing contingency actions, and (4)
whether additional maintenance and monitoring is necessary. The proposed contingency actions
are as follows:
Hydrology. If the hydrology standard is not met, the created wetland will be regraded
in order to ensure that its hydrology matches the hydrologic regime of the existing
wetland.
Plant cover. If plant cover is determined to be below the proposed standard of that
year, plantings may be added to bring the cover up to the specified standard.
Non-native invasive weeds. Infestations of non-native invasive weeds will be removed
prior to planting through hand removal where needed. Re-emergence of the
infestations will be dealt with during routine maintenance. If invasive cover is above
15 percent, maintenance will occur more often until the invasive cover is below 15
percent. The cover of non-native invasive species not currently present onsite will not
exceed 15 percent.
The above actions assume that the reasons for failure to achieve the stated performance standards
for cover are within the control of the land owner or assignee. If natural disasters such as ice
storms or fire impact the mitigation area, appropriate consideration will be taken to determine the
limit of responsibility.
