WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
INTRODUCTION
This report presents the Wetland and Wetland Buffer Mitigation Plan (Mitigation Plan) for the
proposed Pleasant Harbor Master Planned Resort (MPR) near Brinnon in Jefferson County,
Washington (Figure 1 - Vicinity Map). The Pleasant Harbor MPR (Master Land Use Application
[MLA] 06-87) is situated on approximately 257 acres around Pleasant Harbor and Black Point in
Hood Canal and will consist of an 18 -hole championship golf course, residential housing, a marina
and maritime village. GeoEngineers, Inc. (GeoEngineers) was contracted by Statesman Group
(Statesman) to prepare a Mitigation Plan to compensate for impacts to wetland and wetland
buffers as a result of the MPR. This report was prepared utilizing information obtained from site
inspections, the Supplemental Environmental Impact Statement (SEIS) for the Pleasant Harbor
MPR, and the Final Environmental Impact Statement (FEIS) (Jefferson County, 2007), and
addresses the current preferred alternative site plan for the MPR (Figure 2 - Site Map). This
Mitigation Plan proposes to compensate for wetland impacts with on-site and in-kind wetland
creation following the guidelines for compensatory mitigation as outlined in the Washington State
Department of Ecology (Ecology) Wetland Mitigation in Washington State report (Ecology, 2006a
and 2006b), Jefferson County Code (JCC) Chapter 18.22 Part 350 Mitigation (Jefferson County,
2008) and to meet the condition(s) set forth by Jefferson County for wetlands and buffers (MLA 06-
87, Ordinance 01-0128-08). The local jurisdiction and lead environmental review authority is
Jefferson County.
REPORT SCOPE
Statesman is requesting approval for wetland alteration through Jefferson County and Ecology.
Ecology will review this request using administrative orders of the state Clean Water Act (90.48
RCW) under the standards of the 401 Water Quality Certification process (WAC 173-201A). The
United States Army Corps of Engineers (USACE) has determined that the on-site wetlands identified
in the report titled Pleasant Harbor Marina and Golf Resort Wetland Delineation (GeoEngineers,
2006a) are hydrologically isolated; and therefore, are not regulated as waters of the United States
(Appendix A). A Draft Wetland Mitigation Plan Report was prepared in August 21, 2008 and
reviewed by Jefferson County. The comments and suggestions were incorporated in this Final
Wetland Mitigation Plan Report.
The conceptual and final mitigation plans prepared by GeoEngineers will comply with the JCC
pertaining to wetland protection and mitigation criteria, mitigation conditions of the MLA and
Ecology's Wetland Mitigation in Washington State: Part 2 Developing Mitigation Plans, which has
been approved by the USACE and the United States Environmental Protection Agency. This
Mitigation Plan was compiled based on site topography, on-site field reconnaissance and a review
of preliminary development plans.
This Mitigation Plan strictly covers conditions and plans as they relate to wetland alteration. There
are five streams located within the MPR and buffer mitigation plans have been developed for those
streams in a separate Habitat Management Plan (HMP) produced by GeoEngineers in conjunction
with this report (Habitat Management Plan, Pleasant Harbor Master Planned Resort
[GeoEngineers, 2012]).

WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
PROJECT LOCATION
The Pleasant Harbor MPR is located along the western shoreline of the Hood Canal surrounding
Pleasant Harbor and on Black Point in Sections 15 and 22 of Township 25 North, Range 2 West of
the Willamette Meridian. The MPR property, herein referred to as the site, consists of 13 parcels
(50215-2005, -2012, -2013, -2014, -2015, -2016, -3002, -3003, -3020, -3021, -3022, -3023 and
-4002) and is approximately 1.5 miles south of Brinnon in Jefferson County, Washington (Figure 1 -
Vicinity Map). The site is located in the Skokomish-DosewaIlips Water Resource Inventory Area
(WRIA 16) and is part of the East Olympic and Hood Canal Basins. The approximately 257 acre site
(15.2 acres of Washington State Department of Natural Resources [DNR] Lease) is partially
developed and comprised of three main development sections as identified in Figure 1. Section 1
(Golf Course/Golf Resort) is approximately 221 acres on Black Point, which extends east
approximately 1 mile into Hood Canal, and was historically used as the Pleasant Harbor RV Park.
Sections 2 and 3 (Marina/Maritime Village) consist of approximately 36 acres, 15 of which are
aquatic and leased from the DNR, and are located on the northwest shoreline of Pleasant Harbor,
a shallow cove of Hood Canal north of Black Point. Currently, Sections 2 and 3 are being utilized
for a variety of purposes including business (real estate office), recreational (the marina) and
commercial (restaurant and convenience store).
PROJECT DESCRIPTION
Statesman intends to develop a mixed-use resort development on the 257 -acre site. Although two
project alternatives and a no action alternative (three alternatives total) have been developed, the
basic project description remains consistent within the three sections. Section 1 of the proposed
Golf Course/Golf Resort development (sometimes referred to as Black Point Properties) will consist
of an 18 -hole championship golf course, club house, residential facilities and associated
amenities. Sections 2 and 3 will include the mixed-use Maritime Village and Marina. Photographs
of the three sections are located in Appendix B -Site Photographs. The kettles that are referred to in
the alternatives descriptions below are shown on Figure 1.
Description of the MPR Proposal and Alternatives
The site plan alternatives being evaluated in the Pleasant Harbor MPR SEIS include a revised site
plan developed during 2011 to make more efficient use of the site, to minimize environmental
impacts, and to address Jefferson County Board of County Commissioners (BoCC) conditions of
approval (Alternative 1); and the current (2011) site plan revised from the Alternative 1 version,
predominantly in response to the Jefferson County locally -approved Shoreline Master Program
(SMP) update (December 2010) that increases the Shoreline buffer in the Marina/Maritime Village
area from 30 feet to 150 feet (Alternative 2). More descriptive information about each alternative
is provided below.
Features Common to Any Action Alternative
Each of the site plan alternatives includes an 18 -hole golf course, 890 residential units, and
commercial development for resort -related services within the Pleasant Harbor MPR. The location,
configuration, type and number of residential units and commercial space differ somewhat
Page2 January26,2012GeoEngineers,inc.
File No. 126-77-01-08
WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
between the alternatives, as do the amenities to be provided within the development. Structures
within the existing Pleasant Harbor Marina would be renovated or replaced, in both alternatives.
Under either alternative, improvements would be made to Black Point Road, and to the intersection
of Black Point Road with U.S. Highway 101. A 12 -ft wide (with turn -outs) Marina Access Drive
would be improved parallel to the east side of U.S. Highway 101 between Black Point Road and the
existing marina. In order to keep Resort traffic internal to the site to the maximum extent
practicable, the Marina Access Drive would be used by visitors to travel between the main entrance
parking lot and the marina. This drive would accommodate two-way shuttle vehicle service and
emergency vehicle access between Black Point Road and the marina. Access to the Golf
Course/Golf Resort from Black Point Road would be controlled by a gate with a guard house.
Parking for slip owners and Resort visitors would be created at the intersection of Black Point Road
and U.S. Highway 101, with shuttle service from the parking area to the marina using the Marina
Access Drive. The existing real estate office at this intersection would be eliminated. Provisions
would be made for this use within the commercial space of the Maritime Village. Other types of
commercial uses anticipated within the Marina Village include a possible restaurant, dive shop,
sightseeing cruises, gifts, and an upgraded grocery store/convenience store and deli.
The proposed architectural concept for the buildings within the Marina/Maritime Village is a Cape
Cod waterfront style incorporating some stone and cedar accents. Buildings in the Golf Resort,
integrated around the golf course, are proposed in the style of a rustic mountain resort, with stone
detailing, cedar accents, and high -gabled roof elements.
Under either site plan alternative, the main building at the Golf Resort would be the Golf Terrace
and Conference Center/Spa. At four stories in height (approximately 48 feet) for Alternative 1 and
five stories in height for Alternative 2 (approximately 70 feet) and located at approximately
elevation 260 feet mean sea level (msl), this would be the tallest building within the development.
A three-story Maintenance Building/Staff Quarters located near the gated entry to the development
is also a consistent feature of proposed development under either action alternative. The
maintenance portion of this building would provide ground -level golf cart and mower storage, and
servicing and maintenance supplies for the grounds and golf course. Residential units (52) in the
upper two stories would provide housing for employees. Employee parking would be provided in a
surface lot associated with the Maintenance Building/Staff Quarters.
The MPR would be mostly self-sufficient with regard to utilities. An on-site wastewater treatment
plant is proposed, capable of producing Class A reclaimed water for beneficial reuse within the
development. Statesman Corporation received approval of water rights from the Washington
Department of Ecology on June 15, 2010 to serve the site. One or more wells and a water storage
tank will be completed on the property. Stormwater management systems for the control and
treatment of runoff during construction and in the completed condition of the development would
be provided on the site in accordance with the Washington Department of Ecology 2005
Stormwater Management Manual for Western Washington.
Under either alternative site plan, golf course fairways would be located in areas of permeable soils
to allow for infiltration of storm water runoff to recharge the local groundwater aquifer. The first
nine golf course fairways would be developed along the eastern side of the site. The second nine

GEOENGINEERS j File No, 12677-001-08
WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
fairways would be developed along the south and west sides of the property. Portions of the area
to be used for Golf Course development would be left undeveloped (or restored) for the retention of
wetlands and buffers, and for storage of golf course irrigation water (Class A reclaimed water from
the wastewater treatment plant process, and site runoff directed to Kettle B). Existing local
depressions throughout the site would be used to collect and retain runoff for infiltration.
The proposal includes preserving a riparian buffer along the south/southwest bluff of the
peninsula. This buffer would permanently preserve the 200 -foot wide shoreline environment and
the steep slope setback (up to an additional 35 feet wide in places) in a conservation easement to
be administered by one or more local Tribes.
Alternative 1
The Alternative 1 site plan was developed through the BoCC conditions of approval and in response
to the Jefferson County locally -approved SMP update (December 2010), that requires a 150 -ft
shoreline buffer in the marina upland area compared to the 30 -ft setback in the adopted SMP
(1989; revised 1993, 1996, and 1998). The shoreline buffer (i.e., an area where no new
structures would be allowed) significantly modified the Marina Center/Maritime Village
development concept for the MPR.
Redevelopment for maintenance, repair and renovation is now limited to occur within existing
building footprints in the Marina Center (marina upland) area. Therefore, residential and
commercial development proposed in the FEIS site plan for this area is relocated in the Alternative
1 site plan to a new three-story building proposed at the intersection of Black Point Road and U.S.
Highway 101. A new Marina Lofts building at the intersection would include 36 residential units on
the east (rear) side of the building with two stories (12,500 square feet [sf]) of commercial space
at the front (west side, facing U.S. Highway 101). Parking would be provided in surface parking lots
at this intersection for visitors, residents and marina slip owners. An increase in surface parking
would be created on the north side of Black Point Road by a more southerly realignment of the
Black Point Road/U.S. Highway 10 intersection in Alternative 1. Marina rowhouses, townhouses
and stepped/stacked townhouses, illustrated in the FEIS, would be eliminated from the site plan
on the north side of Black Point Road in Alternative 1. A new residential -type structure is proposed
in this area of the Alternative 1 site plan to accommodate group gatherings. Two of these buildings
are proposed: Reunion House and Harbor View House. They would provide a common area and
kitchen facilities for rental residents staying in 12 individual rooms. The Marina Access Drive
would be upgraded to provide access to these two buildings. The Bed and Breakfast Harbor House
owned by others would remain, with a corresponding minor reduction in the overall developable
land area within the MPR compared to the approved FEIS. The Pleasant Harbor House owned by
Statesman may be renovated, with no change to the footprint of the structure. The existing
swimming pool and change room building for marina slip owners would be retained with minor
modifications, or reconstructed. Existing buildings in the marina upland area would be
reconstructed within their existing footprints to house the marina office, a bistro/lounge, showers,
washrooms, and self-service laundry. The existing roadway system and parking areas at the
waterfront would be widened and improved to provide better curve radii, as required by fire
regulations. This would improve safety and ease of access for large vehicles like garbage
collection trucks and emergency vehicles, and provide better connectivity for boaters between
short-term parking and the head of docks for transport between their vehicles and their boats. The

one-way access (Marina Access Drive) from Black Point Road to the waterfront proposed in the
FEIS would be used in Alternative 1 for two-way shuttle service and emergency vehicle access
between the Maritime Village improvements at the Black Point Road/U.S. Highway 101
intersection and the marina. Access to the Washington State Department of Fish and Wildlife
(WDFW) boat launch would be revised to incorporate it with the four-way intersection of Black Point
Road and the Maritime Village and Golf Resort entrances. The total number of residential units
within the Maritime Village area of the MPR would be reduced to 66 new units in three new
buildings, and the existing Pleasant Harbor House, and the Bed and Breakfast House (owned by
others).
Residential units would be increased to 828 in the Golf Course/Golf Resort area, transferred from
reduced development in the Marina/Maritime Village area of the site. In order to reduce the built
or impervious footprint on the site, the majority of residential units (500 units) are now housed in
four Golf Terrace buildings; each four stories in height. The number of original Black Point
Townhouses and Villas has been reduced and renamed the Golf Vistas (76 units, a two story
product on an underground parkade) and 200 Sea View Villas (a one story product on and
underground parkade). The staff quarters and maintenance building has been relocated from the
northwest corner to the northeast corner of the site, but still contains 52 units and remains at
three stories in height. Golf course fairways have been modified slightly from the FEIS proposal.
Tennis courts have been added adjacent to three Golf Terrace buildings, as well as a swimming
pool next to Golf Terrace 3 building. Other Alternative 1 recreational amenities proposed adjacent
to the Golf Terrace 1 building include a bocce ball court, pool and deck area.
The Alternative 1 on-site electrical power generation proposal would utilize an integrated system of
geothermal (geo-exchange) technology, combined heat and power (CHP) derived from co-
generation systems fueled by biodiesel, and limited use of available power from Jefferson County
Public Utility District (JCPUD).
The landscaping proposal includes re -vegetating disturbed areas using healthy trees and shrubs
harvested from areas of the site that will be cleared. Consideration will be given to the use of
native vegetation as well as ornamental shrubs, perennials and annuals in select locations at the
Marina Center, Maritime Village, and Terrace buildings, and along meandering pathways.
Landscape restoration in the Marina Center (marina upland) area of the site is planned to create a
park -like setting, with amenities for seating and sun -rain protection. The proposal includes
creating a temporary native plant nursery south of the wastewater treatment plant site in the area
of Fairway 14, as this fairway will be developed during Stage II construction. A sprinkler irrigation
system using Class A reclaimed water generated by the treatment process will be installed to
temporarily maintain plants kept in this area for relocation during phased development of the site.
Alternative 2
The Alternative 2 site plan was modified to improve constructability by refining the development
within the existing conditions of the site to minimize environmental impacts. The redesign of the
golf course to flow within the existing contours and to minimize site disturbance was a fundamental
factor. The positioning and placement of the buildings were adjusted to ensure that they are
placed on undisturbed soil and to work within the contours.

WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
The Marina Center (marina upland) area has remained as designed in Alternative 1, with minor
changes taking place in the Maritime Village area. The Maritime Village building now includes 42
residential units on the east (rear) side in three stories, with two stories of commercial space
(16,000 sf) at the front. The available parking has increased with the addition of an underground
parkade for residents and staff of the commercial spaces and surface parking lots at the
intersection of U.S. Highway 101 for visitors and Marina slip owners. The Reunion House, Harbor
View House, Pleasant Harbor House and the Bed and Breakfast Harbor House would all remain the
same as Alternative 1. The entire marina upland area would also remain as designed in Alternative
1. The designed intersection of Black Point Road and the access to the WDFW boat launch has
been relocated approximately 1,300 feet to the east of its current location.
Residential units would be decreased by six in the Golf Course/Golf Resort area; transferred from
the increased Maritime Loft building of Alternative 1. In order to reduce the built area, the Golf
Terrace buildings have been increased from four to five stories in height (approximately 60 feet for
Terrace 2, 3 and 4, and 70 feet for Terrace 1). The total number of units within the Golf Terrace
buildings has increased by 20 units to 520 from the Alternative 1 layout. The number of Sea View
Villas has been increased by six units to 206 units total. The Golf Vista units have been decreased
to a total of 44 units. The Maintenance Building/Staff Quarters building and waste water
treatment plant remains the same as Alternative 1. Building positioning has been revised to allow
foundations to be placed on undisturbed soil for the majority of buildings, which allows them to
work with the existing site contours more efficiently than Alternative 1. The golf course has also
been redesigned to allow it to flow and be worked into the existing site conditions. The Alternative
2 recreational amenities have also been repositioned to work better with the existing site layout.
The Alternative 2 on-site electrical power generation proposal would utilize an integrated system of
geothermal (geo-exchange) technology, CHP derived from co -generation systems fueled by
biodiesel, and limited use of available power from JCPUD.
The landscaping proposal includes re -vegetation of disturbed areas using healthy trees and shrubs
harvested from areas of the site that will be regraded, but the amount of disturbed areas will be
significantly reduced from the Alternative 1 plan. Native vegetation, as well as ornamental shrubs,
perennials and annuals, will be placed in select locations at the Marina Centre, Maritime Village
and Terrace buildings, and along meandering pathways. The landscaping in the Marina Center will
follow the Alternative 1 concept.
No Action Alternative
If the Pleasant Harbor Marina and Golf Resort did not proceed, it is presumed (based on the
Comprehensive Plan MPR designation for the property and absence of site-specific zoning',) that
the site would not be further developed at this time. The owner would continue to operate the
285 -berth marina and could perform maintenance, repair and replacement on existing
improvements until a MPR could be successfully implemented, either by the present owner or by
others, or the zoning could be changed back to rural residential through a comprehensive plan
1 The No Action Alternative from FEIS is still valid since the zoning will not change until the Development Agreement and Zoning
regulations are signed by BoCC - see Citizens v. Mount Vernon.

amendment. Campground use of the Black Point Peninsula property could resume under the
existing Conditional Use permit MLA03-00577.
Preferred Alternative
After thorough review of each alternative, it was determined that Alternative 2 was the preferred
choice for development project. Therefore, this report has been written addressing Alternative 2
and the other alternatives will not be addressed further. Alternative 2 site plan is shown on
Figure 2.
Statesman proposes to complete the Pleasant Harbor Marina and Golf Resort over the course of
approximately 10 years, or in response to market demand.
STAGE/: Phase 1
Begin clearing drainage basins that produce no runoff leaving the site (Basins 2, 4, 5, 6, 8, 9,
10, 11, 12 and 13) and that will provide excavated material for construction aggregate
material processing, or for mass fill of Kettles B and C. The entire Kettle B area will be cleared.
Large areas where deep excavation is proposed lie to the south, west, and north of the kettle.
Kettle B will receive approximately 300,000 cubic yards of fill before it can be finish -graded
and lined with synthetic liners to start receiving site runoff and Class A effluent from the
wastewater treatment plant. Liners could be installed during the wet season, though dry
season installation is preferred. Open channels and culverts will be constructed to convey
surface water runoff overflows to infiltration areas within golf course fairways.
Place erosion control measures and redirect runoff into the large kettle (Kettle B) prior to
clearing and rough -grading to create the construction aggregate material processing
site/plant(s). The relatively flat, centrally -located site proposed for materials processing is at
the base of one of several 40 -foot + cut areas. This processed material will be the source of
construction and fill materials for early phases of the project. As excavation progresses and
runoff is directed northward, Drainage Basin 2 will be expanded to the south, which will allow
for additional clearing. If clearing is limited to the south edge of Drainage Basin 2, work could
progress into the wet season. Existing roads on the site could be used to transport materials.
Build the construction aggregate material processing plant and begin operations.
Construct the 260,000 gallon underground water storage facility and water piping to the
existing well. Rough -grade the resort road from the water storage facility to Black Point Road.
Install water main and sewer piping from the water storage facility to Black Point Road in the
resort road alignment.
n Install erosion control measures along the base of the wastewater treatment plant site prior to
clearing. Place fill material behind a retaining wall to create the site for construction of the
wastewater treatment plant. Construct the treatment plant. Construct the co -generation unit
to power the treatment plant.
Clear area south of treatment plant site to create a temporary native plant nursery for trees
and shrubs removed during site development that will be relocated within the project area.

STAGE 1: Phase 2
• Develop the second on-site well. Connect the well to the domestic water distribution system as
soon as practicable after rough grading the areas through which this piping must be routed.
■ Place erosion control measures at the edge of the buffer along the east property line of the
Maritime Village area of the site prior to clearing. Grade the building, parking, and entry roads
to prepare this area for construction.
• Install erosion control measures along the existing (unpaved) marina access drive that
parallels U.S. Highway 101.
• Widen and reconstruct the Marina Access Drive between Black Point Road and the marina.
m Install erosion control measures, implement traffic controls, and relocate utilities in
preparation for constructing improvements to the Black Point Road/U.S. Highway 101
intersection relocation and expansion. Reconstruct and realign Black Point Road and expand
U.S. Highway 101. Underground utility services must cross Black Point Road. The WDFW boat
launch access road intersection with Black Point Road will be reconfigured and reconstructed
concurrent with the Black Point Road/U.S. Highway 101 intersection reconstruction.
® Install the sewage collection system, water distribution/temporary fire -protection system, reuse
water systems, electrical power transmission, and communications facilities to serve the
wastewater treatment plant, the marina area, and Maritime Village Building.
• Construct Maritime Village building, Harbor View House, Reunion House, roads, utilities, and
parking lots.
• Widen existing roadways to 20 feet for two-way and 12 feet for one-way travel, and provide
turnarounds. Construct a new section of road between the existing marina access road and
upper parking area to increase the curve radius for larger vehicles including firefighting
equipment.
• Clear and excavate the small "hill" from U.S. Highway 101 on the north side of the marina
access road to improve sight distance and visibility for entering vehicles.
® Relocate the fuel storage tanks and equipment closer to U.S. Highway 101, near the unused
pool.
STAGE 1: Phase 3
® Relocate existing marina office, convenience store, deli, and self-service laundry to the new
Maritime Village building.
• Remodel/reconstruct the Marina Center (marina upland) commercial uses.
• Remodel/reconstruct existing swimming pool and change building at the marina.
• Install sewage pumps and force mains to convey sewage from the marina and marina upland
facilities to the wastewater treatment plant. Abandon the existing septic tank drain field that
now serves the marina buildings and moored vessels.
STAGE 11: Phase 1
Construct the wetland in the bottom of the south kettle (Kettle C). Kettle C is to be converted
to a created wetland with an enhanced buffer. The bottom of the basin will be filled
Page 8 January26, 2012 GeoEngineers, lnc.
File No. 12671-01-08
WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
approximately 30 feet to create a depressional kettle wetland. Fill materials will be selected
from on-site materials that have low permeability, such as those that may be found in the
existing wetland to be filled in the large kettle (Kettle B). Buffer enhancement will include
clearing invasive plant species and replacement with native plant material harvested from the
site or purchased from local nurseries. Temporary irrigation may be required for the wetland
and the buffer plantings to improve the survival rate during the first growing season. The
existing closed drainage basin and the drainage basin created in the developed condition
around Kettle C will provide and maintain hydrology for the created wetland. When wetland
creation in Kettle C is complete, construct a fence around the buffer edge to prevent
construction activities and resort visitors from entering and potentially damaging the wetland
and buffer vegetation.
Place erosion control measures along the east property line buffer of the Golf Course/Golf
Resort area of the site near Black Point Road to prepare this area for construction of the Golf
Terrace 1 access road. Excavated materials from the Maintenance Building/Staff Quarters
area and from Fairways 3 and 4 could be used to construct this road embankment. Install the
storm drainage system within the road to direct runoff to storm water treatment and detention
facilities.
Complete the Golf Terrace 1 building pad and associated parking areas. This construction may
not require significant additional erosion control measures since the runoff can be directed to
the enclosed drainage basin to the south.
Install the sewage collection system, water distribution system, fire protection system (a
function of the fairway/landscape irrigation system), reuse water systems, power transmission,
and communications facilities to serve the Golf Terrace 1 building, and the Maintenance
Building/Staff Quarters.
• Install erosion control measures and clear sufficient area during the dry season to rough -grade
Fairways 11 and 12 and construct the embankment for Fairway 10, including a lined detention
pond. This grading will form Drainage Basin 1. Large areas of excavation lie to the east and
west of Fairway 10 and the building site to the north. The detention pond will have a synthetic
liner to prevent soil saturation. Pumps will be permanently installed adjacent to this pond to
move collected runoff northward into the irrigation pond (Kettle B). These pumps will be
powered by cogeneration units. Construction of the embankment, pond, pumps, force mains,
and soil stabilization must be completed during the dry season. It might be necessary to delay
completion of Fairways 7, 8, 9, 10 and part of Fairway 11 until the dry season in the following
yea r.
• Install erosion control and wetland buffer area protection along the west side of Wetland D
(along the east property line of the Golf Course/Golf Resort area of the site) before work begins
on Fairways 3, 5, 6 and 8. Since this drainage basin (Basin 10) discharges to Wetland D and
then off site, it may require that clearing and grading in this area occur in the dryseason.
Fairways 1, 2, 3, 12, 13, 14, 15, 16, 17, and 18 could be worked during wet weather. The
area north of Fairway 14 may require additional erosion control measures near the wastewater
treatment plant site in order to work during wet weather conditions. The preferred method of
fairway construction will proceed in the order of clearing and grubbing, rough grading, drainage
installation, irrigation installation, fine grading, and seeding progressing along the fairways
GEOENGINEERS January26,2012" Page9
File No. 12677-001-08
WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
using specialized types of equipment. This will allow a minimum of clearing and grubbing to
occur and will reduce the amount of time the ground is being actively worked. The fairways in
many cases can be seeded and stabilized before the wet season arrives.
Rough -grade roads, driveways, and building pads for improvements that will be made in
Stage II Phase 2 and Stage II Phase 3 as part of adjacent fairway construction. Installation of
underground wet and dry utilities can be delayed until the Stage II Phase 2 and Phase 3
building construction occurs. Sanitary sewer service will require pumping raw sewage from the
south-central portion of the site. A pump station will be required near the south end of the
pond (Kettle B).
STAGE 11: Phase 2
■ Install erosion/sedimentation control measures around building construction sites to protect
completed portions of the golf course (if any). Buildings to be constructed in Stage II include
Golf Terrace 2 west of Fairway 16; Golf Terrace 3 north of Fairway 12; Golf Terrace 4 east of
Fairway 17; Golf Vistas south of Fairway 15 and west of Fairway 18 and the Maintenance
Building/Staff Quarters north of Fairway 4.
■ Extend roads and utility services to the Stage II Phase 2 building sites.
w Construct two sanitary sewer pump stations: one to the west of Kettle B to serve building
construction to the west and southeast, and one adjacent to the Maintenance Building/Staff
Quarters to serve that building and buildings to the south.
Construct the sanitary sewer pump station and co -generation unit at the Maintenance
Building/Staff Quarters.
Reconstruct Black Point Road from the end of Stage I Phase 2 intersection improvements east
of U.S. Highway 101 to the resort east entrance in the northeast corner of the Golf Course/Golf
Resort area of the site. Install erosion/sedimentation control measures, as required.
STAGE 11: Phase 3
n Install erosion/sedimentation control measures around building construction sites for the Sea
View Villas adjacent to Kettle B, north of Fairways 10 and 11, west of Fairway 8, and south of
Fairway 4; and Golf Vistas east of Kettle C.
® Extend roads and utility services to the Stage II Phase 3 building sites.
m Construct the sanitary sewer pump station at the southeast corner of the site to serve the Sea
View Villas west of Fairway 7, north of Fairway 10, and north of Fairway 11.
PROPOSED MITIGATION PROJECT
Mitigation Project Description
The MPR will incorporate an on-site water treatment and recycling program into the layout of the
golf course and residential dwellings in Section 1 (Golf Course/Golf Resort). The on-site water
program will impact one wetland (Wetland B within Kettle B) that will be used as a control pond for
the water treatment system. This pond will collect water from the MPR and recycle for use by the
golf course irrigation system. The on-site recycling of water will decrease the amount of fresh water
Page 10 January26, 2012 GeoEngineers, Inc.
File No. 12577-01.08
WETLAND AND WETLAND BUFFER MITIGATION PLAN, PLEASANT HARBOR RESORT Jefferson County, Washington
The soils will be saturated within 12 inches of the surface, or standing water will be present for
a consecutive number of days greater than or equal to 12.5 percent of the growing season.
Positive indicators of wetland hydrology can be used to identify if this measurement has been
achieved.
Acceptable cover standards for the wetland trees and shrubs:
■ end of year 1: minimum of 20 percent
■ end of year 3: minimum of 30 percent
■ end of year 5: minimum of 40 percent
Acceptable cover standards for the wetland herbaceous species will be at least 80 percent.
SITE PROTECTION
Statesman will protect this mitigation site from disturbance including logging, mining, development,
and selling of the mitigation areas by putting the land in a conservation easement.
MAINTENANCE
Maintenance of the wetland creation areas will be conducted throughout the monitoring years and
will be the responsibility of Statesman to ensure completion. Maintenance during the first two
years will include periodic watering (irrigation) and control of undesirable species. Maintenance
during the subsequent years will be focused on invasive plant removal. Also, if crowding of newly
planted vegetation by grass species is determined to affect plant survival during the monitoring
events, the maintenance company will return to trim grasses from around the drip lines of the
planted vegetation.
Irrigation of the wetland creation area may be required for the first 2 years after installation of
native plants. A temporary irrigation system may be utilized or a regular watering schedule
established if on-site water is not available. Watering during the plant establishment period is
crucial for plant survival. During the dry months, usually June through September, it may be
necessary to add up to 3 gallons of water per plant per week. Extremely warm weeks may
necessitate watering on a more frequent basis. An irregular watering interval will encourage the
development of deep root systems, which in time will reduce the need for any future watering.
Control of undesirable species will be maintained by periodic invasive species removal from the
mitigation area. Species to be removed primarily include exotic invasive species such as: reed
canarygrass, Himalayan blackberry, cutleaf blackberry and Scot's broom. Only desirable native
volunteer species in addition to those planned for the area will be encouraged to grow. Wetland
buffer slopes will be reseeded with grasses if deemed necessary due to erosion or sedimentation
into the newly created wetland areas. Some of the other maintenance responsibilities such as
trash removal and vandalism repair will be performed on an as -needed basis.

CONTINGENCY PLAN
If the project fails to meet the standards discussed above, implementation of a contingency plan
will be required by Ecology and Jefferson County. The contingency plan will supplement the
wetland mitigation plan and will be based on assessments made during mitigation monitoring
events and additional site visits. As problems are recorded, suggestions and possible solutions will
be forwarded to Ecology and Jefferson County as a component of the monitoring reports.
GeoEngineers will work in conjunction with Ecology and Jefferson County to develop the
contingency plan. The plan will anticipate problems and specifically address issues such as the
eradication of invasive species, supplemental irrigation as required, replacement plant installation
of deceased plants, damaged or missing structures or vandalism. The plan will follow the protocol
set forth in this Mitigation Plan and also provide greater detail about specific measures required to
help the site meet its goals, objectives and performance standards.
If more than 20 percent mortality of plantings occurs within any of the monitoring years, the
problem areas will be replanted, preferably in the dormant season and with improved maintenance
to ensure higher plant survival. If, in the judgment of the monitoring biologist, alternative plant
species are needed to improve survival, alternative species will be selected.
IMPLEMENTATION SCHEDULE
Statesman will follow the timeline approved and agreed upon by the regulatory agencies in regards
to the development of the MPR and the construction of the mitigation areas. The anticipated
timeline for this project is shown below in Table 8. The monitoring reports need to be submitted to
Jefferson County no later than December 31 in each of the monitoring years. The actual year the
first monitoring report will be completed will depend on when the as -built report is completed.

Dear Mr. Wright,
am
P.O. BOX 3765
SEATTLE, WASHINGTON 98124-3755
Statesman Corporation
This letter concerns your request for confirmation of a wetland delineation and
determination of no jurisdiction for property located in an existing campground on the Olympic
Peninsula adjacent to Hood Canal near Brinnon, Jefferson County, Washington. After reviewing
your submitted information and visiting the site we have detennined that wetlands "b", "c" and
"d" shown on the enclosed map are not waters of the United States. As such, the work that
would occur within these wetlands marked on the enclosed drawing does not require Department
of the Army authorization under Section 404 of the Clean Water Act, This approved
jurisdictional determination is valid for a period of 5 years from the date of this letter unless new
information warrants revisions of the determination.
Other state and local regulations may still apply to these wetlands. For example, the
Washington State Department of Ecology (Ecology) regulates isolated wetlands. You should
contact Ecology's Office of Regulatory Assistance's One -Stop Service Center at (800) 917-0043
or ec, �)ac ii��ec,.wa.yov for more information on how to obtain State approval for your project.
We are sending a copy of this letter to Ecology and to the Environmental Protection Agency's
Aquatic Resources Unit.
A copy of this letter with enclosures will be sent to the Washington Department of Ecology,
Office of Regulatory Assistance's One -Stop Service Center and GeoEngineers. If you have any
questions about this letter or any aspect of our regulatory program, please contact me at (206)
764-5529 or via email marcy.r.reedCqJ�ace.a�rm.m�il.

n Decision supported by SWANCC/Migratory Bird Rule Information Shoo for Determination of No
Jurisdiction.
BASIS OF JURISDICTIONAL DETERMINATION:
A. Waters defined under 33 CFR part 329 as *navigable waters of the United States":
[] The presence of waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in
the past, or may be susceptible for use to trans22rt interstate or foreign commerce.
B. Waters defined under 33 CFR part 328.3(s) as "waters of the United States":
0 (1) The presence of waters, which are currently used, or were used in the past, or may be susceptible to use in into -Awe
or foreign commerce, including all waters which are subject to the ebb and flow of the tide.
(2) The presence of interstate waters including interstate wetlands'.
❑ (3) The presence of other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats,
sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or
destruction of which could affect interstate commerce including any such waters. (check all that apply),
n ( i) which are or could be used by interstate or foreign travelers for recreational or other purposes.
0 Oil from which fish or shellfish are or could be taken and sold in interstate or foreign commerce.
C3 (iii) which are or could be used for industrial purposes by industries in interstate commerce.

Does the wetland being rated meet any of the criteria below? If you answer YES to any of the questions below you will
neea to protect the wetlana accorame to the rep -orations resarame the speciai characteristics tonna in the wetland.
SPI. Has the wetland unit been documented as a habitat for any Federally listed Threatened or
Endangered animal or plant species (TIE species)?
For the purposes of this rating system, "documented" means the wetland is on the appropriate
state or federal database.
SP2. Has the wetland unit been documented as habitat for any State listed Threatened or
Endangered animal species? For the purposes of this rating system, "documented" means the
wetland is on the appropriate state database. Note: Wetlands with State listed plant species
are categorized as Category I Natural Heritage Wetlands (see p. 19 of data form).
SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state?
SP4. Does the wetland unit have a local significance in addition to its functions? For example, the
wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or
in a local management plan as having special significance.
To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated.
The hydrogeornorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland
functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. Seep. 24 for mare detailed inst uctians on classifying wetlands.

Wetland name or number B
Classification of Vegetated Wetlands for Western Washington
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a'unit with
multiple HGM classes'. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.
1. Are water levels in the entire unit usually controlled by tides (i.e. except during floods)?
NO — go to 2 YES — the wetland class is Tidal Fringe
's the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine)
Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and
this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please
note, however, that the characteristics that define Category I and H estuarine wetlands have changed (seep. ).
2. The entire wetland unit is flat and precipitation is only source (>90%) of water to it. Groundwater and surface water
runoff are NOT sourc�astsified
e unit.
YES —The wetland class is Flats
If your wetland cas a "Flats" wetland, use the form for Depressional wetlands.
3. Does the entire wetland meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on
the surface) where at least 20 acres (8ha) in size;
❑ At least 300/6 of th n water area is deeper than 6.6 (2 m)?
NO — go to—4--) YES — The wetland class is Lake -fringe (Lacustrine Fringe)
4. Does the entire wetland me�iilro—f the following criteria?
❑ The wetland is on a slope (slope can be very gradual).
❑ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow
subsurface, as sheetflow, or in a swale without distinct banks.
❑ The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow de ressions or behind hummocks (depressions are usually <3 ft diameter and less than I foot deep).
NO —`go to 5 YES — The wetland class is Slope
5. Does the entire wetlan-c meet all of the following criteria?
❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river.
❑ The overbank flooding occurs at least once every two years.
NOTE: ei4r nit can contain depressions that are filled with water when the river is not flooding..
NOTE:
— go to 6� YES — The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of
the year. This means that any outlet, if pres &4g r an the interior of the wetland.
NO —_go to 7 YES — TV wetland class is Depressional
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not
pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The
wetland may be ditche o obvious natural outlet.
No —go to 8 YES — The wetland class is Depressional
Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a
slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO
BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the
rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in
the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less
than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area.

Which of the following priority habitats are within 330 ft. (IOOm) of the wetland? NOTE: the connections do
not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if
there are any questions.
II Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both
aquatic and terrestrial ecosystems which mutually influence each other.
II Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres)

multi -layered canopy with occasional small openings, with at least 20 trees/ha (8 trees/acre) > 81 cm
(32 in) dbh or > 200 years of age.
Q Mature forests: Stands with average diameters exceeding 53cm (21 in) dbh; crown cover may be less
than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally
less than that found in old-growth; 80 — 200 years old west of the Cascade Crest.
Q Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases
and/or forbs form the natural climax plant community.
II Talus: Homogenous areas of rock rubble ranging in average size 0.15 — 2.Om (0.5 — 6.5 ft), composed
of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be
associated with cliffs.

Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage
0
of the oak component of the stand is 25%.
Q Urban Natural Open Space: A priority species resides within or is adjacent to the open space and
uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting
other priority habitats, especially those that would otherwise be isolated; and/or the open space is an
isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban
development.
j] Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi -enclosed by
land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water
is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically
increased above that of the open ocean by evaporation. Along some low-energy coastlines there is
appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean -
derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both
estuaries and lagoons.
II Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and
may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs,
snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and
that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion

less than 10% cover of non-native plant species. If the non-native Spartina spp,. are only species
Cat. II
that cover more than 10% of the wetland, then the wetland should be given a dual rating (I/II).
The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh
with native species would be a Category 1. Do not, however, exclude the area of Spartina in
determining the size threshold of 1 acre.

Natural Heritage Wetlands (seep. 87)
Natural Heritage wetlands have been identified by the Washington Natural Heritage Program/DNR as
either high quality undisturbed wetlands or wetlands that support state Threatened, Endangered, or
Sensitive plant species.
SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a natural heritage wetland? (This
question is used to screen out most sites before you need to contact WNHP/DNR.)

SC3
Bogs (seep. 87)
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use
the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the
wetland based on its function.
I. Does the unit have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that
compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to
identify organic soils)? YES = go to question 3 NO = go to question 2
2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over
bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or
pond? YES = go to question 3 NO = is not a bog for purpose of rating
3. Does the unit have more than 70% cover of mosses at ground level, AND other plants, if present,
consist of the "bog" species listed in Table 3 as a significant component of the vegetation (more
than 30% of the total shrub and herbaceous cover consists of species in Table 3)?
YES = Is a bog for purpose of rating NO = go to question 4
NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that
criterion by measuring the pH of the water that seeps into a hole dug at least 16" deep. If the pH is
less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog.
4. Is the unit forested (> 30% cover) with sitka spruce, subalpine fir, western red cedar, western
hemlock, lodgepole pine, quaking aspen, Englemann's spruce, or western white pine. WITH any of
the species (or combination of species) on the bog species plant list in Table 3 as a significant
component of the ground cover (> 30% coverage of the total shrub/herbaceous cover)?

SC4
Forested Wetlands (seep. 90)
Does the wetland have at least I acre of forest that meet one of these criteria for the Department of Fish
and Wildlife's forests as priority habitats? If you answer yes you will still need to rate the wetland
based on its function.
❑ Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi-
layered canopy with occasional small openings; with at least 8 trees/acre (20 trees/hectare) that are
at least 200 years of age OR have a diameter at breast height (dbh) of 32 inches (81 cm or more).
NOTE: The criterion for dbh is based on measurements for upland forests. Two -hundred year old trees
in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW
criterion is and "OR" so old-growth forests do not necessarily have to have trees of this diameter.
❑ Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 — 200 years old
OR have an average diameters (dbh) exceeding 21 inches (53 cm); crown cover may be less than
100%; decay, decadence, numbers of snags, and quantity of large downed material is generally
less than that found in old-growth.

Classification of Vegetated Wetlands for Western Washington
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with
multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question S.
1. Are ater levels in the entire unit usually controlled by tides (i.e. except during floods)?
NO — go to 2 YES — the wetland class is Tidal Fringe
s the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine)
Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms forRiverine wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and
this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please
note, however, that the characteristics that define Category I and II estuarine wetlands have changed (seep. ).
2. The entire wetland unit is flat and precipitation is only source (>90%) of water to it. Groundwater and surface water
runoff are NOT sour c the unit.
NO — go to 3 YES — The wetland class is Flats
If your wetland can be c assified as a "Flats" wetland, use the form for Depressional wetlands.
3. Does the entire wetland meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on
the surface) where at least 20 acres (8ha) in size;
❑ At least 30% of th n water area is deeper than 6.6 (2 m)?
NO — go to—4--) YES — The wetland class is Lake -fringe (Lacustrine Fringe)
4. Does the entire wetland meet a of the following criteria?
❑ The wetland is on a slope (slope can be very gradual).
❑ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow
subsurface, as sheetflow, or in a swale without distinct banks.
❑ The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallowde ressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep).
NO --'go to 5 YES — The wetland class is Slope
5. Does the entire wetlanTmeet all of the following criteria?
❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river.
❑ The overbank flooding occurs at least once every two years.
NOTE e unit can contain depressions that are filled with water when the river is not flooding..
NO —go toO YES — The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of
the year. This means that any outlet, if pres than the interior of the wetland.
NO — go to 7 YES — wetland class is Depressional
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not
pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The
wetland may be ditche o obvious natural outlet.
No — go to 8 YES — The wetland class is Depressional
If y
Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a
slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zcne of flooding along its sides. GO
BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the
rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in
the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less
than 10% of the unit classify the wetland using the class that represents more than 90% of the total area.

Which of the following priority habitats are within 330 ft. (100m) of the wetland? NOTE: the connections do
not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if
there are any questions.
II Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both
aquatic and terrestrial ecosystems which mutually influence each other.
II Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres)
II Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft.
II Old-growth forests: (Old growth west of Cascade Crest) Stands of at least 2 tree species, forming a
multi -layered canopy with occasional small openings, with at least 20 trees/ha (8 trees/acre) > 81 cm
(32 in) dbh or > 200 years of age.
II Mature forests: Stands with average diameters exceeding 53cm (21 in) dbh; crown cover may be less
than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally
less than that found in old-growth; 80 — 200 years old west of the Cascade Crest.
II Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases
and/or forbs form the natural climax plant community.
II Talus: Homogenous areas of rock rubble ranging in average size 0.15 — 2.Om (0.5 —6.5 ft), composed
of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be
associated with cliffs.
[l Caves: A naturally occurring cavity, recess, void, or system of interconnected passages.
II Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage
of the oak component of the stand is 25%.
Q Urban Natural Open Space: A priority species resides within or is adjacent to the open space and
uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting
other priority habitats, especially those that would otherwise be isolated; and/or the open space is an
isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban
development.
[1 Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi -enclosed by
land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water
is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically
increased above that of the open ocean by evaporation. Along some low-energy coastlines there is
appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean -
derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both
estuaries and lagoons.
II Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and
may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs,
snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and
that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion
control).

SC3
Bogs (seep. 87)
Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use
the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the
wetland based on its function.
I. Does the unit have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that
compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to
identify organic soils)? YES = go to question 3 NO = go to question 2
2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over
bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or
pond? YES = go to question 3 NO = is not a bog for purpose of rating
3. Does the unit have more than 70% cover of mosses at ground level, AND other plants, if present,
consist of the "bog" species listed in Table 3 as a significant component of the vegetation (more
than 30% of the total shrub and herbaceous cover consists of species in Table 3)?
YES = Is a bog for purpose of rating NO = go to question 4
NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that
criterion by measuring the pH of the water that seeps into a hole dug at least 16" deep. If the pH is
less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog.
4. Is the unit forested (> 30% cover) with sitka spruce, subalpine fir, western red cedar, western
hemlock, lodgepole pine, quaking aspen, Englemann's spruce, or western white pine. WITH any of
the species (or combination of species) on the bog species plant list in Table 3 as a significant

Q Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi-
layered canopy with occasional small openings; with at least 8 trees/acre (20 trees/hectare) that are
at least 200 years of age OR have a diameter at breast height (dbh) of 32 inches (81 cm or more).
NOTE: The criterion for dbh is based on measurements for upland forests. Two -hundred year old trees
in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW
criterion is and "OR" so old-growth forests do not necessarily have to have trees of this diameter.
Q Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 — 200 years old
OR have an average diameters (dbh) exceeding 21 inches (53 cm); crown cover may be less than
100%; decay, decadence, numbers of snags, and quantity of large downed material is generally

Classification of Vegetated Wetlands for Western Washington
If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with
multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.
1. Are water levels in the entire unit usually controlled by tides (i.e. except during floods)?
NO — go to 2 YES — the wetland class is Tidal Fringe
s the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?
YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine)
Ifyou r wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it
is rated as an Estuarine wetland Wetlands that were call estuarine in the first and second editions of the rating system are called Salt
Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and
this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please
note, however, that the characteristics that define Category I and H estuarine wetlands have changed (seep. ).
2. The entire wetland unit is flat and precipitation is only source (>90%) of water to it. Groundwater and surface water

If your wetland can be c assified as a "Flats" wetland, use the form for Depressional wetlands.
3. Does the entire wetland meet both of the following criteria?
❑ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on
the surface) where at least 20 acres (8ha) in size;
❑ At least 300/6 of th n water area is deeper than 6.6 (2 m)?
NO — go to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe)
4. Does the entire wetland meet a -of the following criteria?
❑ The wetland is on a slope (slope can be very gradual).
❑ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow
subsurface, as sheetflow, or in a swale without distinct banks.
❑ The water leaves the wetland without being impounded?
NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and
shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep).
NO --'*go to 5 YES — The wetland class is Slope
5. Does the entire wetlann eet all of the following criteria?
❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river.
❑ The overbank flooding occurs at least once every two years.
NOTE: nit can contain depressions that are filled with water when the river is not flooding..
O — go to 6 YES — The wetland class is Riverine
6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of
the year. This means that any outlet, if pr r than the interior of the wetland.
NO — go to 7 YES —The wetland class is Depressional
7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not
pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The
wetland may be ditche o obvious natural outlet.
No — go to 8 YES — The wetland class is Depressional
Your wetland unit seems too be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a
slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO
BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT
AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the
rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in
the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less
than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area.

Which of the following priority habitats are within 330 ft. (100m) of the wetland? NOTE: the connections do
not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if
there are any questions.
F l Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both
aquatic and terrestrial ecosystems which mutually influence each other.
Q Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres)
Q Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft.
II Old-growth forests: (Old growth west of Cascade Crest) Stands of at least 2 tree species, forming a
multi -layered canopy with occasional small openings, with at least 20 trees/ha (8 trees/acre) > 81 cm
(32 in) dbh or > 200 years of age.
II Mature forests: Stands with average diameters exceeding 53cm (21 in) dbh; crown cover may be less
than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally
less than that found in old-growth; 80 — 200 years old west of the Cascade Crest.
Q Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases
and/or forbs form the natural climax plant community.
Q Talus: Homogenous areas of rock rubble ranging in average size 0.15 — 2.Om (0.5 — 6.5 ft), composed
of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be
associated with cliffs.
F1 Caves: A naturally occurring cavity, recess, void, or system of interconnected passages.
II Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage
of the oak component of the stand is 25%.
II Urban Natural Open Space: A priority species resides within or is adjacent to the open space and
uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting
other priority habitats, especially those that would otherwise be isolated; and/or the open space is an
isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban
development.
Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi -enclosed by
land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water
is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically
increased above that of the open ocean by evaporation. Along some low-energy coastlines there is
appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean -
derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both
estuaries and lagoons.
II Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and
may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs,
snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and

Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use
the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the
wetland based on its function.
1. Does the unit have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that
compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to
identify organic soils)? YES = go to question 3 NO = go to question 2
2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over
bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or
pond? YES = go to question 3 NO = is not a bog for purpose of rating
3. Does the unit have more than 70% cover of mosses at ground level, AND other plants, if present,
consist of the "bog" species listed in Table 3 as a significant component of the vegetation (more
than 30% of the total shrub and herbaceous cover consists of species in Table 3)?
YES = Is a bog for purpose of rating NO = go to question 4
NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that
criterion by measuring the pH of the water that seeps into a hole dug at least 16" deep. If the pH is
less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog.

❑ Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi-
layered canopy with occasional small openings; with at least 8 trees/acre (20 trees/hectare) that are
at least 200 years of age OR have a diameter at breast height (dbh) of 32 inches (81 cm or more).
NOTE: The criterion for dbh is based on measurements for upland forests. Two -hundred year old trees
in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW
criterion is and "OR" so old-growth forests do not necessarily have to have trees of this diameter.
❑ Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 — 200 years old
OR have an average diameters (dbh) exceeding 21 inches (53 cm); crown cover may be less than

Is the wetland west of the 1889 line (also called the Western Boundary of Upland Ownership or
WBUO)?
YES = Go to SC 6.1 NO Q not an interdunal wetland for rating
If you answer yes you will still need to rate the wetland based on its junctions.
In practical terms that means the following geographic areas:
• Long Beach Peninsula -- lands west of SR 103
• Grayland-Westport -- lands west of SR 105
• Ocean Shores-Copalis — lands west of SR 115 and SR 109
SC 6.1 Is the wetland one acre or larger, or is it in a mosaic of wetlands that is one acre or larger?
YES = Category II NO = go to SC 6.2
SC 6.2 Is the wetland between 0.1 and 1 acre, or is it in a mosaic of wetlands that is between 0.1 and I acre?
Cat. Il
YES = Category III
Cat. III
Category of wetland based on Special Characteristics
♦
Choose the "highest" rating if wetland falls into several categories, and record on p. 1.
If you answered NO for all types enter "Not Applicable" on p. I

PLANT DESCRIPTIONS
Big Leaf Maple (Acer macrophylla): This tall tree has a
massive, squat main trunk and soaring, huge vertical limbs.
In the open, it forms a round, spreading crown, while in a dense
stand it becomes a tall straight tree. It has long clusters of
yellow flowers in the spring, and very large, lobbed leaves
which turn yellow in the fall. Various birds eat its two -winged
"helicopter" fruits, and the leaves provide foliage for deer and
elk. Young trees grow rapidly in the spring (Thurston County
Conservation District, 2008). It grows in dry to moist sites,
often with Douglas fir and often on sites disturbed by fire,
clearing or logging at low to middle elevations (Pojar and
MacKinnon, 1994).
Douglas Fir (Pseudotsuga menziesii): This tree grows well in
various soil types, especially in sunny areas. It has flat needles
that are sharp -pointed but not prickly, and many medium-sized
cones that drop to the ground each fall. The ridged Douglas fir
bark on older trees is fire-resistant because of its thickness.
An uncrowded tree has pyramidal crown with dense foliage.
Deer and rodents browse on the seedlings, and small birds and
mammals eat the seeds. It needs well -drained soil and full sun
but is located everywhere from extremely dry, low elevation
sites to moist mountain sites (Thurston County Conservation
District, 2008; Pojar and MacKinnon, 1994).
Pacific Willow (Salix lucida ssp. lasiandra): This tree typically has one or more
leaning, crooked trunks and an upright to rounded form. It can grow 20- to
40 -feet tall as a deciduous shrub or tree and grows in coastal dune wetland
communities along the outer coast and coastal freshwater swamps around
Puget Sound (Department of Ecology, 1993). The branches are brown and
twigs glossy, with yellow, duckbill -shaped buds that are usually hairless and
brittle at base. The bark is fissured yellowish -brown on older trees. This plant
is found along riverbanks, floodplains, lakeshores and wet meadows.
It tolerates full sin to partial shade and prefers moist soils (Pojar and
MacKinnon, 1994).

Red Alder (Alnus rubra): This tree is fast growing and can reach
up to 60 to 100 feet tall. It is a deciduous tree, usually single
stemmed and forms pure stands or intermixes with Western Red
Cedar and Western Hemlock. Red alder is intolerant of shade
and will grow in nitrogen -deficient soils due to its ability to fix
atmospheric nitrogen. This tree provides food for grouse,
pine siskin, black -capped chickadee, kinglet and beaver and is a
common nest tree for great blue heron (Department of Ecology,
1993). It tends to grow in moist woods, streambanks,
floodplains, slide tracks, and recently cleared land and is often
found in pure stands and at low elevations (Pojar and MacKinnon,
1994).
Western Red Cedar (Thuja plicata): This is a sweet-smelling,
coniferous evergreen tree that likes moist soil but can also
survive in drier habitats. It grows slowly, but can grow to heights
of between 60 and 200 feet. As it grows, its crown becomes open
and its lower branches droop. Clusters of small brown cones
grow at the ends of the branches (Thurston County Conservation
District, 2008). Instead of needle leaves, it has tiny scales set
snugly on the branches and it is resistant to rot and fungus
(Pojar and MacKinnion, 1994). It provides protective and nesting
cover for wildlife and also provides twigs and foliage for browsers.
Its bluish -black, berry -like fruit is important to many large and
small birds and mammals (Martin et al., 1961).
Evergreen Huckleberry (Vaccinium ovatum): This plant has glossy,
dark green leaves on many erect, hairy branches which start at
the base of the plant. It produces purplish -black fruits.
New shoots are bronzy red, and mature foliage is often reddish
purple (Thurston County Conservation District, 2008). It is found
in the understory of coniferous forests (especially edges and
openings) at low elevations. It also prefers shade and grows in
moist to dry sites (Pojar and MacKinnon, 1994).

Pacific Ninebark (Physocarpus capitatus): Pacific ninebark is a deciduous
shrub that grows to about 15 feet tall. It typically grows in moist but
well -drained soils along streams, in full sun to part shade (Department of
Ecology, 1993). It also grows in wet, somewhat open spaces (streamside
thickets, edges of moist woods, coastal marshes, meadows, margins of
lakes and streams) and occasionally on drier, shrubby sites (Pojar and
MacKinnon 1994). The twigs and greenery provide browse for girds and
wildlife.
Salal (Gaultheria shallon): This plant is a robust, evergreen
shrub which often forms dense thickets. It has lustrous,
dark -green leaves, showy pink flower clusters, and purplish -black
berries that are eaten by birds, rodents and people. Salal can be
damaged by the strawberry root weevil (Thurston County
Conservation District, 2008). It occurs in the understory of
coniferous forests and rocky bluffs and is found in low to medium
elevations. It likes partial shade to deep shade and is found in
moist to dry sites (Pojar and MacKinnon, 1994).
Salmonberry (Rubus spectabilis): This shrub can grow 3 to
10 feet high and has shredding, light- or golden -brown bark.
It has woody sparsely thorned stems; and zigzag twigs.
Flowers are large (about 1112 inches across), borne singly, and
are pink to dark or purplish -red. Large raspberry -like fruits
appear in late spring, ripening over a fairly long period to
become yellow to red or deep purple (United States Army
Corps of Engineers, 2005). Salmonberry grows in moist to
wet places, and is often abundant along stream edges,
avalanche tracks and in wet logged areas. It prefers full sun
to full shade (Pojar and MacKinnon, 1994).

Vine Maple (Acer circinatum): This shrub can grow up to 20 feet
tall and has sprawling branches that often form thickets and
colonies. The leaves are green during the summer but during the
fall they turn either golden in the shade or bright red in full sun.
It has white flowers that form in clusters at the end of the shoots
and winged fruits that turn red or brown. This plant grows in moist
to wet places and prefers partial to deep shade which typically
occurs under tree canopies (Pojar and MacKinnon, 1994).
Sword Fern (Polystichum munitum): This evergreen shrub will
typically reach 2 to 21/2 feet in height and 4 feet in diameter.
The leaves are narrow lance -shaped pinnately dark green with
fringed edges. Large orange spores appear on the underside of
each leaf. The roots are rhizomes (Thurston County
Conservation District, 2007). Typically found in moist forests at
low to middle elevations, it is abundant and widespread
throughout the Pacific Northwest (Pojar and Mackinnon, 1994).
Slough sledge (Carex obnupta): This herbaceous plant
grows one to three feet tall and spreads by rhizomes to
form monotypic stands. It is limited to western Washington
and required wet soils to flourish. The plant can tolerate
deep shade or full sun and commonly grows in red
alder -dominated swamps in association with skunk
cabbage, water parsley and salmonberry (Department of
Ecology 1993).

Lady Fern (Athyrium felix-femina): Lady fern is a deciduous
perennial fern that can grow to four feet tall. It spreads by
rhizomes slowly and eventually spreads to form clusters of
individual plants. It grows in partial shade to full shade and
prefers wet to moist soils (Department of Ecology, 1993). It is
commonly found in moist to wet forest, swamps, thickets,
openings, slidetracks, streambanks, gullies, meadows and
clearings (Pojar and MacKinnon, 1994).
Small -fruited bulrush (Scirpus microcarpus): This herbaceous plant
grows between two to four feet tall and is a deciduous perennial
herb. It spreads by rhizomes to form monotypic stands in
saturated soils and shallow seasonal standing water. It is
commonly found along streams and in freshwater marshes
(Department of Ecology, 1993). Stems are usually clustered, from
a sturdy rhizome, stout, triangular, leafy, to 1.5 meters tall.
It grows in full sun and prefers wet to shallow water (Pojar and
(MacKinnon, 1994).
