THIS AGREEMENT is made between the PORT OF PORT ANGELES, a municipal
corporation organized and existing under the laws of the State of Washington (hereafter
the "Port") and the City of Port Angeles, a noncharter code city of the State of
Washington (hereafter the "City The agreement is made in light of the following facts.
The Port has applied for permits to fill an industrial pond on the Port Angeles
waterfront. As a condition for issuance of the permits, regulatory agencies are requiring
the Port to mitigate the filling of 3.91 acres of water surface area with the construction of
an equal area of new wetlands. The Port has received final permit approval based on
a two site mitigation plan contained in the K -PLY LOG POND FILLING PROGRAM Final
Intertidal Habitat Restoration /Mitigation Plan and Associated Project Monitoring Process,
prepared by Watershed Dynamics, dated August 1, 1993, (hereafter the "Plan
(Attachment 1).
The Plan details the construction of a 2.5 acre marine estuary on a 4 -acre Port
owned site at the mouth of Valley Creek on the Port Angeles waterfront and a 1.5
intertidal beach at the Morse Creek mitigation site, owned by the City of Port Angeles, on
property designated for construction of the future Tozier Marine Park. On October 19,
1993, the Port Angeles City Council approved, in concept, the Port's use of approximately
1.5 acres of the City's Morse Creek site for mitigation in accordance with the conceptual
proposal presented in the Plan and approval of and agreement between the Port and the
City detailing each party's responsibilities in the ultimate construction of the intertidal
beach and the future Tozier Marine Park.
This Interlocal Governmental Agreement is entered into by and between the parties
in consideration of the mutual benefit to be derived by the parties therefrom, it is hereby
agreed as follows:

K -PLY LOG POND FILLING PROGRAM
Intertidal Habitat Restoration/Mitigation Plan and
Associated Project Monitoring
A cooperative watershed restoration oroaram undertaken by the Port of
Port Angeles. the City of Port Angeles. and the Lower Elwha S'Klaiiam Tribe.
PURPOSE OF THE INTERTIDAL HABITAT RESTORATION /MITIGATION
The activity for which this intertidal habitat restoration/
mitigation plan is being prepared is the proposed filling of
the log storage pond at the K -Ply Mill in Port Angeles,
Washington.
The K -Ply log pond fill will eliminate 3.91 acres of area identified as "waters
of the state." As compensation for this fill, the Port proposes to created 4.12
acres of an interactive intertidal stream /estuarine community and an
associated upland area.
The primary stated objectives of this proposed activity are:
1. Improvements in the layout of the log handling and
sorting yard adjacent to the wood processing
facilities. The target is a reduction in costs
associated with the operation and maintenance of log
yard facilities, improvements in surface water quality
discharges, and improvements in human safety in the
mill area.
2. The need for the Port of Port Angeles to recreate
valuable and productive intertidal and nearshore areas
as a primary element of the restoration of fish and
wildlife populations within the Port Angeles area.
3. Improvements in the management of water quality on the
site from both surface water and process water
management.
4. Containment of hazardous materials present in the log
pond which can be capped in place using clean,
uncontaminated fill. This allows the Port to undertake
remedial actions to eliminate an existing body of water
contaminated by years of wood waste and presently
providing very limited habitat value.
1
5. Consolidation of industrial area to allow for a more
distinct separation between the downtown commercial
center and the ongoing industrial activities of the
Port of Port Angeles.
6. Reduction through yard consolidation and vegetation
screening in the amount of noise and dust within the
downtown Port Angeles area as a result of industrial
activities.
As a part of the Port's process in the development of this
restoration /mitigation plan the Port has aggressively sought
inputs from the various resources agencies at the state,
federal, local, and Tribal levels. From the outset, the
Port has been concerned that the filling of the log pond be
adequately offset by the creation of appropriate intertidal
and estuarine habitats. Although the Port recognizes that
the existing open water features are highly degraded with
little of no habitat value, the Port wanted to insure that
high quality habitat could be created in close proximity to
the harbor waterfront area.
In the process of gathering comments on how best to off -set
the impacts of proposed log pond filling, the Port reviewed
an issue paper on aquatic habitat mitigation prepared for
the Washington Public Ports Association (WPPA) (Gallaghar,
1992). This issue paper deals primarily with mitigation of
future activities within developed port areas. The paper's
focus is on impacts avoidance, minimization, and
compensation. However, several goal statements are also
directed towards habitat restoration.
The WPPA issue paper also identifies a Washington Department
of Fisheries Policy Statement (No. 410) wherein the
Department of Fisheries establishes three specific goals
with respect to habitat management. The first goal deals
with the concept of "no net loss." The second goal
identifies the restoration of the productive capacity of
habitats presently damaged or degraded high priority. The
third goal directs the improvement of existing habitats and
created new habitats.
The Department of Fisheries' very clearly stated goal is "to
achieve no net loss of productive capacity of the habitat of
fish and shellfish resources of the state." In keeping with
the spirit of this very clear goal, the Port's mitigation
proposal fills an industrial log pond area which has been
degraded to a point of zero production capacity and replaces
it with an area of greatly improved production capacity for
fish and shellfish resources. The result of the Port's
efforts will be a net gain in the productive capacity of the
habitat of fish and shellfish resources of the state.
2
The Department of Fisheries policy specifically identifies
the strategy for meeting the goal of restoration as
improving "the production capacity of habitats that have
been damaged by natural causes or by the results of man's
activities." In the strategy discussion of this goal it is
stated that "the preferred method of accomplishing
restoration will be to have those responsible for the damage
do the restoration voluntarily cooperative project
wherein the Department and the responsible party jointly
address the problem will be considered."
In an effort to assist the Washington Department of
Fisheries with meeting its policy goals, the Port has
evaluated the existing log pond and has determined that the
most appropriate restoration process is to cap the presently
contaminated pond with clean fill materials and recreate
more diverse habitats in close proximity to the pond.
In addition to helping the Washington Department of
Fisheries, the Port has taken this opportunity to create
intertidal and adjacent upland wildlife habitats which meet
environmental objective, the separation of the downtown
business area from the Port's industrial area, and the
implementation of basin planning and restoration efforts.
This program will also become a focus of local public
education and involvement in natural resource systems and
habitat stewardship programs.
The Port's efforts -to restore habitats also works hand -in-
hand with the policies and directives of several resource
agencies. For example, the Washington Department of Natural
Resources (DNR) has the power to lease state -owned aquatic
lands (Chapter 79.90 RCW). Within the lease program the DNR
is directed to consider the "natural values of state -owned
aquatic lands as wildlife habitat, natural area preserve,
representative ecosystem, or spawning area prior to issuing
any initial lease or authorizing any change in use."
Further, the DNR has the ability to provide within any lease
for the protection of such natural values.
These efforts have been supported by the City of Port
Angeles, the City's Downtown Business Association, local
public interest groups, and the Lower Elwha S'Klallam Tribe.

DOCUMENT PURPOSE
This Intertidal Habitat Restoration /Mitigation Plan and
Associated Proiect Monitoring document outlines the
procedures proposed by the Port of Port Angeles to provide
environmental habitat compensation for the impacts
associated with the proposed log pond filling. This
restoration /mitigation project requires the excavation of an
adjacent upland area immediately east of the log pond. The
mitigation area is presently being used for log storage and
sorting. The Port's proposed mitigation would resurrect
approximately 600 feet of Valley Creek from its present
culvert. The project would also create instream habitat
making the creek a vital component of the estuary
restoration project. In addition, the creek would become a
key link in the future restoration of the entire Valley
Creek Watershed.
Prior permitting activities undertaken by the Port of Port
Angeles for this project site include a previous Corps of
Engineers Public Notice OYB -4- 0104780, dated 29 July 1992.
This previous Corps application has been cancelled. A
Shoreline Management Permit has been issued by the City of
Port Angeles for the proposed log pond fill activity (SMA
91(08)119 dated August 20, 1991). In addition, permit
applications has been submitted to Clallam County for a
Disposal Site Permit and to the Washington State Department
of Fisheries for a Hydraulic Permit Approval (HPA).
GOAL OF THE RESTORATION /MITIGATION PLAN
The GOAL of the proposed restoration /mitigation plan is to
provide compensation for environmental impacts associated
with the filling of the K -Ply log pond. The Plan will
created a viable, interactive, freshwater stream /estuarine
habitat complex within an urbanized, marine waterfront.
The created habitat complex will provide the environmental
elements required to support a wide range of fish, wildlife,
and plants. It will also meet the objectives identified in
the City of Port Angeles Master Plan for waterfront
recreational and educational opportunities.

SITE HISTORY
BACKGROUND INFORMATION
Until the early 1900's much of what is now downtown Port
Angeles existed as low lying waterfront (shoreline) and
shallow subtidal area. To increase dry land available for
commerce and industry the area was gradually filled over a
40 year period which ended in the early 1950's (Figure 1).
During the late 1920's, a rail line was constructed to
connect the Port's marine terminal with various wood
processing facilities located in the inner harbor on the
west side of downtown Port Angeles. Part of the track was
constructed on a wooden trestle, the remnants of which are
buried in the seawall that defines the northern boundary of
the proposed project. The seawall construction and
subsequent filling of tidal areas began at this site in
1941.
In the area of the existing log pond, no fill was placed and
the ground was excavated to an elevation varying between
-3.0 feet to -6.0 feet Mean Low Low Water (MLLW). In
addition, a tide gate installed through the trestle /seawall
fill to allow for passage of logs from the harbor into the
new log yard. For the next 48 years the pond served as a
holding area for fir and cedar logs prior to processing in
the adjacent plywood mill and various lumber mills operating
from time to time in the nearby industrial area.
In the late 1980's, the plywood mill was sold by ITT
Rayonier to the Klukwan Indian Tribe, a Native American
Corporation, and the mill renamed K -Ply. In 1989, K -Ply
began experimenting successfully with processing cottonwood
for plywood veneer and over the last two years the mill's
production has converted almost exclusively to the project.
Unlike cedar and fir, cottonwood does not float very long
and the need for the pond has been eliminated.
Additionally, the location of the pond now creates a
hindrance to the efficient operation of the mill, resulting
in long haul distances to feed the mill from the upland
storage yard.
During the filling of the downtown Port Angeles area, began
in the early 1900's, Valley Creek, which originally emptied
onto the harbor south of the existing log pond, was placed
in a culvert to extend it's mouth to the north side of the
railroad trestle. This trestle became the northern boundary
of ongoing fills. The exact years of the action are unknown
but based upon observed differences in culvert construction
5
and geometry it is assumed that the extension of the mouth
of the creek to it's present discharge occurred in a number
of phases.
The property between Oak Street, Cherry Street, and Valley
Creek bordered on the south by Front Street and on the north
by the harbor was the final area of downtown to be filled.
This action took place in the early 1950's with the material
being hydraulically dredged from near shore and placed
behind the pre- existing railroad trestle /grade. Since
filling, this area has remained undeveloped and has been
used primarily for log storage and handling for the plywood
mill.
PORT OF PORT ANGELES INDUSTRIAL AREA
The majority of the project area in zoned by the City of
Port Angeles as "M -2 Industrial District" and has been used
primarily for wood processing activities over the past
several decades. The proposed action, which is the purpose
of this permit application, is to fill an existing log
storage pond. This log storage pond, which until recently
has been used as a vital part of the adjacent industrial
activities, has a wetted surface area of 3.91 acres.
The current layout of the log handling /sorting area used for
staging logs prior to their entering the milling process is
significantly hampered by the presences of the log pond. In
an effort to improve the log handling process and enhance
the intertidal habitat within the property, the Port of Port
Angeles proposes to fill the pond (Figure 2).
HABITAT ASSESSMENTS. LOG POND AREA
During May 1991, a preliminary habitat survey was completed
of the present log pond (Thom, 1991) The purpose of this
survey was to identify and characterize the quality and
types of vegetated and unvegetated marine habitats in the
study area.
The survey concluded the shoreline habitats in the log pond
were poorly suited for feeding or rearing of fish or
invertebrate resources. The water quality was highly
degraded and adjacent upland vegetation was generally sparse
in cover and highly disturbed. These factors significantly
limit the use of the log pond or its shoreline by
terrestrial animals (Thom, 1991).
6
In July 1992, a biologist with the U.S. Fish and Wildlife
Service visited the log pond site to evaluate fish and
wildlife resources of concern (Frederick, 1992). The
biologist noted that the log pond is classified in the
National Wetland Inventory map as estuarine, subtidal, open
water, and that saltwater intrusion into the pond presently
occurs through the tide gate. Also noted was that the
classification of the pond could be further characterized as
"diked /impounded."
The July site visit noted that the pond's poor water quality
was attributable to the lack of regular flushing and
accumulated log debris in the pond. Vegetation surrounding
the pond was sparse and the sideslopes were steep. Also
noted were the presence of wildlife which included a great
blue heron (Ardea herodias), twelve mallard ducks (Anas
nlatvrhvnchos), two belted kingfishers (Cerlve alcvon), and
several swallows (Tachvcineta spp.).
The USFWS biologist noted that while the pond may be
presently poorly suited for fish and shellfish as
characterized by prior analysis, the site appeared to be
used by some a number of species tolerant of degraded
habitat conditions. Also, it was noted that the kingfishers
appeared to be foraging in the pond (Frederick, 1992).
During the fall and early winter of 1992/1993 biologists
from Watershed Dynamics, Inc. (WDI) visited the project site
on several occasions to evaluate prior information and the
existing site conditions. The log pond did not appear to
have a substantially different character than that presented
in past survey and site visit reports. The sideslopes of
the log pond are very steep, poorly vegetated. The slopes
are also extensively covered with asphalt chunks, concrete
slabs, wood waste, discarded metal items, broken log wrap
cable, and a variety of other waste products typically found
in this kind of industrial site. The plant species observed
were predominantly invasive species that typically establish
in disturbed sites. For example, patches of Scot's broom
(Cvtisus sconarius) were present along the pond shoreline
and along the top of the rip rap berm adjacent the harbor.
Wildlife observations WDI noted the presence of at least
three species of waterfowl, a great blue heron, and a number
of smaller birds around the log pond. Observed were
mallards, American wigeon (Anas americana), Barrow's
goldeneye (Bucenhala islandica), song sparrow (Melosoiza
melodia), common raven (Corvus corax), starling (Sturnus
vulaaris), and rock dove (Columbia livia). None of the
wildlife observed were actively feeding in the log pond.
The waterfowl appeared to be resting in the quiet waters of
the pond.
7
Observations along the harbor area adjacent the project area
shoreline identified the resting and feeding activities of
great blue heron, mallards, Barrow's goldeneye, American
wigeon, Thayer's gull (Larus thaveri), herring gull (Larus
araentatus), hooded merganser (Louhodvtes cucullatus), red
breasted merganser (Meraus serrator), bufflehead (Buceohala
albeola), surf scoter (Melanitta nersoicillata), pigeon
guillemot (Cepohus columbal, common murre (Uria aalae),
double- crested cormorant (Phalacrocorax auritus), and
Western grebe (Aechmoohorus occidentalis). Also observed
was a single harbor seal (Phoca vitulina) which stayed
approximately 200 feet offshore.
Anecdotal information gathered during discussions with log
yard operations personnel noted that several bird species,
particularly great blue heron and mallards, resting along
the protected shoreline area of the log pond during times of
high wind and wave activities. Feeding activities by these
birds has not been observed within the log pond since the
last time the tide gate was opened more than three years
ago. When the tide gate was opened, log yard personnel
would occasionally see a great blue heron feed on what was
thought to be fish drawn into the log pond. Such feeding
activities would only last a few days following the closure
of the pond.
The steep sided shoreline and amount of woody debris within
the log pond made seining of the pond for fish population
analysis extremely difficult. Electrofishing spot surveys
completed in January 1993 by WDI at a few locations along
the pond's edge, the observers failed to capture any fish.
LOG POND HABITAT CLASSIFICATION
Following the U.S. Fish and Wildlife Services methodologies
(Cowardin, et.al., 1979) the existing log pond would be
classified as Estuarine. Subtidal, Unconsolidated Bottom,
water chemistry Mixohaline. special modifiers. Excavated and
Diked /Imuounded (ElUB3xh). According to Dethier, et.al
(1990), the substrata modifier should be "artificial bottom"
rather than unconsolidated bottom because the bottom of the
pond is made up of wood wastes and discarded junk (Thom,
1991)
8
WATER QUALITY ASSESSMENT. LOG POND AREA
The tide gate located between the log pond and the Port
Angeles harbor area has not been opened for several years.
However, a very limited amount of surface water appears to
leak around the plate connections of the tide gate as shown
by the attachment of barnacles, mussels, and some seaweeds.
This leakage does not appear significantly large enough to
allow fish passage but does allow some limited movement of
macroinvertebrate larva as evidenced by the attached
barnacles and mussels (Thom, 1991).
The log pond presently receives untreated site runoff, non
contact cooling water, boiler blowdown discharges, and
scrubber effluent from the adjacent milling operations and
upland log sorting /storage areas (Landau, 1988). These
industrial discharges are regulated by the Washington
Department of Ecology through the NPDES permit program. The
primary discharge point is noted within the present NPDES
permit as the tide gate. This discharge point thus
identifies the log pond as a part of the treatment system.
Filling of the pond would require a modification to the
present NPDES permit (Luster, 1993).
Water samples from the log pond were tested for volatile
organic compounds in 1988. The only compound detected was
methylene chloride. The conclusion was that the log pond
water did not appear to contain significant amounts of the
colvent compounds that frequently are associated with
industrial pollution (Landau, 1988).
Untreated site runoff from the log storage and sorting areas
are also directed into the Port Angeles Harbor.
9
FILL QUALITY ASSESSMENT. LOG POND AREA
The log pond was created in 1941 to serve the needs of
adjacent milling operations. The log pond was created by
the placement of rock fill along the existing railroad
trestle followed by fill placement between the railroad and
First Street. The majority of this initial fill placement
was accomplished by hydraulic dredging of the harbor area.
A tide gate was installed to maintain a water depth of
approximately 6 feet during all tidal levels. When opened,
this tide gate connected the log pond to the harbor and
allowed logs to be floated into and out of the log pond.
The fill, used for log pond and upland creation consisted
primarily of soil and rock materials (Landau, 1988). While
the present pond contains substantial amounts of wood
debris, no evidence of the disposal of drums, chemicals, of
other potentially hazardous materials were found in the fill
area (Landau, 1988). Sampling of the pond sediments tested
for total oil and grease, selected phenols, arsenic,
chromium, copper, and zinc. Test results indicated that
only total oil and grease was detected at significant levels
(940 ppm) and that all other tested analytes were below
detection limits of present in concentrations that are close
to expected background concentrations (Landau, 1988).
As part of recent planning efforts undertaken by the Port of
Port Angeles to assess potential concerns with the log pond,
Shannon and Wilson (1992) provided the Washington State
Department of Ecology (WDOE) with information about the
existing character of the fill materials within the log
pond. The primary consideration was the potential that
existing materials may leach into adjacent aquatic
environments if the log pond were filled.
The Shannon and Wilson (1992) report identified elevated
levels of several contaminants within the log pond fill
materials. Included within this analysis were very high
levels of Total Organic Carbon (TOC). Following a review
this information, WDOE has noted that the identified TOC
levels may act to prevent contaminants from leaching out of
the log pond area (Luster, 1993).

VALLEY CREEK DESCRIPTION
Valley Creek (WRIA #18 -0249) originates in the lower
foothills north of the northern boundary of the Olympic
National Park and flows northward to its terminus in the
Port Angeles Harbor Area. The upper portions of this
drainage have been modified by prior and ongoing harvest
operations resulting in a mosaic of timber stands of varying
age and hydrologic character. The lower portion of the
watershed, north of U.S. Highway 101, is within the City
limits of Port Angeles and has been modified by past
development activities.
As the stream system enters the City of Port Angeles area
stream gradient becomes somewhat moderate with well defined
channel shape. More than 60% of the Valley Creek drainage
is defined as urban land use with approximately 50% of the
urban land use consisting of impervious surfaces (Tetra
Tech, 1988). Numerous sections Valley Creek have been
culverted through the Port Angeles Area for roads and
channel controls. The last 2,000 feet of Valley Creek is
culverted under Valley Street before discharging into the
harbor area. Approximately 600 feet of this final culvert
in within Port of Port Angeles property.
Information about the extent of anadromous salmonid
utilization of the Valley Creek System is limited (Mike
McHenry, per.comm.). The Washington Department of Fisheries
Stream Catalog (Williams, et.al. 1975) notes that suitable
spawning gravels for anadromous salmon are present in the
lower areas of Valley Creek and that coho salmon
(Oncorhvnchus kisutch) and chum salmon (Oncorhvnchus keta)
may use the Valley Creek System. However, this catalog
suggests that the run of coho salmon is believed extinct
within Valley Creek, as well as within adjacent small
streams in the Port Angeles Area.
One of the primary features identified as a limiting factor
to the utilization of the Valley Creek System by anadromous
salmon is poor accessibility caused by urbanization,
particularly improper culvert installation (Williams,
et.al., 1975).
A site specific survey of a portion of Valley Creek at
approximately river -mile 1.2 (Highway 101 area) during 1982
captured and identified 10 cutthroat trout (Salmo clarki,
now Oncorhvnchus clarkii) and 1 brown bullhead (Ictalurus
nebulosus) using standard electorshocking techniques (Araya,
et.al. 1982). The larger two cutthroat measured
approximately 8 and 11 inches. The brown bullhead was
believed to have been released into the system (Araya,
et.a1.1982).

ENVIRONMENTAL FUNCTIONS AND VALUES OF EXISTING LOG POND
Wetlands and aquatic areas are known to perform various
functions that are beneficial to the environment and have
intrinsic value. These functions include hydrologic
support, storm and flood water storage, water quality,
shoreline protection, groundwater exchange, base flow
regulation, and natural biological habitats (Table 1). The
value of these functions is dependent upon various wetland
characteristics, effected fish and wildlife populations, and
the location within the watershed.
In addition to intrinsic functions, extrinsic functions are
also a recognized indirect value of wetlands. Educational
and recreational opportunities are most often mentioned as
extrinsic functions. Their values are often "in the eye of
the beholder" and are difficult to evaluate. As such, these
functions are typically not rated but are nonetheless
important when considering restoration or enhancement
projects.
The existing log pond appears to provide a very limited to
no aquatic or terrestrial habitat. A small number of
species, typically associated with disturbed site conditions
and urban areas, have been observed in the log pond area.
The minor amount of surface water leakage through the
existing tide gate allows macroinvertebrates to settle on
the inside of the tide gate. The protected nature of the
log pond also allows a limited number of avian species to
use the area as refuge habitat. Mallards were often
observed resting in the quite water areas of the log pond.
The disturbed character, limited vegetation cover, steep
sided slopes along the edges on the log pond, and the nearly
constant film of petrochemicals floating on the water's
surface would act to restrict waterfowl nesting
opportunities.
The log pond also appears to provide a limited amount of
feeding habitats, particularly for avian species. Great
blue heron and belted kingfishers have been observed onsite
apparently feeding or retrieving previously dropped food
organisms in the pond area. Other bird species have also
been observed feeding on the wide range of insects over the
pond and within the limited vegetation along the shoreline
of the pond. The log pond does not appear to provide
significant usable habitat for small mammals. A few Norway
rats (Rattus norveaicus) were observed along the outer edges
of the adjacent breakwater.

Information synthesized from Reppert et al, 1979 and Adamus et. al, 1987
The log pond does not provide habitats for a wide diversity
of plants or animals. Also not present are unique habitat
features (ie. snags, perching trees), or unique plant and
animal species. When analyzed following the three estuarine
habitat functions identified within the Estuarine Habitat
Assessment Protocol (Simenstad, et.al.,1991) (discussed
later in this document) the existing log pond is severely
lacking in any of the primary mechanisms of estuarine
habitats.
The primary function provided by the log pond is the
treatment of point and non -point pollutants. The log pond
is presently used as a part of the NPDES permit for water
discharges at the onsite K -Ply mill. In addition, surface
water runoff from onsite log sorting and storage areas are
directed into the log pond. However, lack of vegetation
within and along the shoreline of the log pond limits the
ability of the log pond to undertake adequate biofiltration
of these waters.
RELATIONSHIP TO THE LOG POND TO AQUATIC AND UPLAND
RESOURCES
The existing log pond is, for the most part, isolated from
adjacent aquatic and upland resources. The only sources of
freshwater into the log pond are the result of storm event
runoff passing over adjacent industrial areas and discharges
for the milling operations. A very limited amount of marine
water leaks through the existing tide gate.
There appears to be very limited interaction between the
existing log pond and adjacent harbor areas. Detrital
drift, which is typically of great benefit to adjacent
marine habitats, fish, and wildlife, does not occur. There
are no vegetated corridors connecting the existing log pond
with adjacent upland habitats and there are no habitats
within the log pond that support significant fish or
shellfish populations.
13
DEVELOPMENT ALTERNATIVES ANALYSIS
As presented by several of the resource and permitting
agencies participating in project review, to be consistent
with the Clean Water Act, Section 404(b)(1) Guidelines, no
fill shall be authorized if there are practicable
alternatives to the proposed discharge which would have less
adverse impact on the aquatic ecosystem. One primary
consideration in the review of proposed fill material
discharge actions is the extent that the proposed action
requires access or proximity to or siting within a special
aquatic site to fulfill the basic purpose of the project.
The analysis of the "water dependency" of proposed actions
is a vital component to project evaluations and adequacy of
proposed impact mitigation.
The proposed activity is the placement of approximately
125,000 cubic yards of fill material into a presently
existing log storage pond. This pond was created through a
combination dredging and fill placement. The pre- existing
habitat would most likely have been classified as estuarine,
subtidal, unconsolidated bottom. The primary purpose of the
log pond was to maintain a water depth of approximately 6
feet by which logs could be stored and efficiently directed
into the onsite milling operations. The design of both the
log pond and the onsite mill allowed the feeding of logs
into the milling process by a chain drive carriage system
partially submerged in the pond. Logs were guided through
the pond by mill workers using long pike poles.
Over the years of operation, raw logs were placed into the
log pond by a number of different methods. The tide gate
allowed logs to be floated into the log pond from the
adjacent harbor area. This tide gate also allowed logs to
be sorted either within the log pond or on adjacent upland
areas to be bundled in the pond and taken into the harbor
area for storage or transportation to other ports. Raw logs
transported to the area via truck, train, or log rafts were
sorted and stored on upland areas and placed into the pond
to meet milling needs. In addition, an area directly
adjacent the eastern edge of the log pond was developed to
allow log rafts to be remove and placed into the harbor.
These log rafts could go directly into the log pond or be
placed upland and used as needed to meet milling needs.
The location of the entire milling operation is greatly
enhanced by its proximity to the marine environment. This
proximity allows both the efficient and economical handling
of raw and processed wood products. Adjacent harbor
facilities provide for the transportation needs of the
area's mills and log handling operations, as well as wood
fiber export operations.
14
As noted above, the present milling operation is designed to
feed raw logs directly from the log pond into the first mill
process. The design worked very well when conifer trees
such as Douglas fir (Pseudotsuaa menziesii), Western red
cedar (Thula olicata), and Western hemlock (Tsuaa
heteronhvlla) were the primarily species processed.
However, the onsite milling operation has been modified and
the primary tree species utilized at the mill is black
cottonwood (Pooulus trichocarna).
The primary use of black cottonwood presents a problem to
the continued efficient handling of logs onsite. The
sorting and storage of black cottonwood within log ponds is
not practicable because this species has a tendency to sink
after a short period of time in the pond. As such, raw logs
can no longer be placed in the log pond and efficiently fed
into the milling process.
With the inability to use the existing log pond for
efficient mill operations, raw logs must now be sorted and
stored east of the log pond and hauled the entire distance
around the mill to be fed into the initial process. The
long haul distance and increased handling creates a
hindrance to efficient and economical operation. One other
important consideration is that this increased hauling and
handling has also increased concerns for human safety in the
mill area and increased noise and dust in nearby downtown
Port Angeles.
Modification of existing site conditions is required for the
onsite mill operation to remain economically competitive,
reduce site safety concerns, and reduce onsite dust and
noise. This need has led to a development of these site
planning alternatives:
No Action Alternative: Following this alternative there would
be no change in onsite conditions. The existing log
pond would remain in its present conditions. Raw logs
would continue to be stored onsite but at some distance
away from the mill and travel and handling distances to
feed the mill would remain long. The result of travel
and handling distances would continue to be increased
noise and dust in the central business district of the
City of Port Angeles. Onsite raw log handling costs
would remain high and continue reducing the economic
competitiveness of the mill.
In addition, presently accumulated wood waste sediments
on the existing pond bottom would remain and the log
pond would continue to serve as a treatment location of
onsite stormwater and mill operations discharges.
15
Partial Fillina of Loa Pond: Following this alternative there
would be a limited amount of increase in raw log
handling efficiency onsite. This alternative would
propose filling only the western 1/2 to 3/4 of the
existing log pond. Transport of raw logs directly to
mill's feed location would be improved and travel
distances would be reduced. Log storage would,
however, remain at an increased distance away from the
mill and transport /handling costs would remain high.
The levels of noise and dust would also remain high in
the City of Port Angeles area.
Under this alternative the remaining eastern 1/4 to 1/2
of the log pond may offer an area for intertidal
habitat restoration and the creation of an upland
buffer. However, the water dependent log handling area
directly east of the log pond would need to remain in
operation. This would significantly limit the extent
to which the present log pond could be enhanced. Any
required mitigation for the portion of the log pond
filled could not be contiguous to the eastern portion
of the remaining log pond due to the need to have
continued assess to this barge berth and shoreside log
handling facility. In addition, presently accumulated
wood waste sediments on the existing pond bottom and
the removal of the wooden railroad trestle buried in
the northern berm separating the log pond from the
harbor would be prohibitively expensive. The log pond
would continue to serve as a treatment location of
onsite stormwater and mill operations discharges.
Filling the Entire Loa Pond: This alternative creates upland dry
log storage area adjacent to the mill, improves log
handling to feed the mill by reducing transport
distances, and retains the barge berth and shoreline
log handling area. Operational efficiency and
production economics are greatly enhanced. Noise and
dust within downtown Port Angeles would be reduced.
By following this alternative the water dependent uses
of the entire site would be greatly enhanced. Site
facilities would be centralized and onsite safety
conditions would improve.
A: On site /In kind Identical Habitat Reolacement: Following
this alternative the entire area of the present log
pond would be replaced with an identical adjacent log
pond. This new log pond would be very steep sided,
lined with vertical bulkheads, lack habitat diversity,
and not be connected via surface waters to either the
harbor or Valley Creek. Under this alternative the
mitigation area would be almost the same as the present
16
log pond. One primary element of the present pond that
would not be included into the new pond would be the
accumulation of several feet of wood wastes.
While this alternative would be an exact in -kind
replacement and appear to meet the mitigation ideas of
several agencies, it would not meet the primary stated
objectives of the overall project. This alternative
would not create valuable and productive intertidal and
nearshore areas as an element of the restoration of
fish and wildlife populations in the Port Angeles area.
B: On site Habitat Replacement of Greater Diversity: Following
this alternative the total area of the existing log
pond would be replaced with a variety of interactive
habitats. This alternative would create an intertidal
stream /estuarine community and associated upland areas
of diverse native vegetation and fish and wildlife
habitats.
While not a direct consideration of the alternative
selection process, mitigation for this total fill
alternative would allow for a watershed approach to the
restoration and enhancement of aquatic systems within
the Port Angeles Harbor Area. Any required mitigation
for the loss of aquatic habitats presently provided
within the log pond could target the recreation of
viable freshwater and estuarine interactive systems.
Such mitigation could also include educational and
recreational opportunities to be coordinated with
present City of Port Angeles waterfront planning and
the Valley Creek Watershed Restoration Planning
efforts.
Several other alternatives were discussed and removed from
consideration because they either did not meet the project
objective or were completely cost prohibitive. These
alternative included mill process re- direction, relocation
of the mill, and a complete bridge over the existing pond.
Associated with a recent application to convert the log pond
for short term use as a graving area for I -90 Bridge
construction, the Port of Port Angeles conducted an in -depth
investigation into possible locations within the Port
Angeles Harbor for mitigation sites. At the time, two sites
on Port owned land were identified.
Tumwater Creek Corridor: This creek flows through the Port's
Marine Terminal west of the K -Ply mill. The mouth of the
creek is immediately adjacent to Terminal 3, the Port's most
highly utilized export cargo berth and the log booming
grounds where logs are placed in the water for transport to
shipside for loading or to other mills within Puget Sound.
17
Upland, the stream flows in a narrow corridor dividing the
Port's back -up land for it's Marine Terminal support. This
land is the most intensely utilized of all Port property and
supports the largest single revenue source for the Port.
Due to it's location, the only habitat enhancement
opportunity reasonably feasible would be increased planting
along the stream bank for shading and the possible addition
of berms to the stream band to prevent adjacent log yard
run -off from entering the stream.
Valley Street to Cherry Street Waterfront: The suggestion made by
the USFWS during the previ permit review was to create an
intertidal wetland in the vicinity of Cherry Street. The
present proposal contemplates just that, with the additional
enhancement of opening the northern 600 feet of Valley Creek
and directing it into the constructed intertidal area at
Cherry Street, thus creating a marine estuary.
Non Port Properties: Most other property with the harbor is
intensely developed with manufacturing or commercial and
tourism facilities. However, some site were investigated.
Daishowa Mill Pond: The Port investigated the
possibility of some expansion or enhancement of this
wetland. Based upon previous studies by the mill owner
is was determined that due to the nature and extent of
wood and other contaminants in the sediment, it was not
economically practical to undertake -a project on this
site.
Peabody Creek: Located on the eastern edge of the
Central Business District, this stream runs beneath the
cities three main streets. Any attempt to create
additional intertidal areas or stream restoration
project at the location would require a complete
revision and re- routing of Highway 101 and other
traffic in downtown Port Angeles.
Wetland East of the Red Lion Motel: The remains of a small
wetland exists immediately to the east of the Red Lion
Motel. The site is approximately 1/2 acre. A small
bridge on the waterfront trail and a 48" diameter
industrial waterline cross a narrow channel connecting
this area with the harbor. Two problems were noted
with trying to enhance or expand this site. First the
area is bordered on the east and south by steep, wet,
unstable slopes and expansion of the wetland could
result in serious slope stability problems. Secondly,
the small opening to the harbor is closed off with
beach deposition which naturally occurs. To keep the
channel open would require an on -going maintenance
program which could adversely effect any developing
habitat.
1 Q
PLAN COMPONENTS
INTERTIDAL HABITAT RESTORATION /MITIGATION
PLAN COMPONENTS
The proposed intertidal restoration /mitigation and estuarine
habitat creation plan has been designed to optimize
estuarine habitats associated with a small stream system.
These estuarine habitats, not presently available within the
local area, will be restored and enhanced to support a wide
range of fish, wildlife, and plant species of local,
cultural, and regional importance.
The plan is centered on the complete mitigation of all impacts associated
with the filling of the existing log pond. However, this existing log pond has
very limited habitat function and value and does not presently support
anadromous salmonid or shellfish resources. In addition, there is no viable
upland community adjacent to the existing pond to provide cover and
habitat for the open water and shoreline areas. As such, the
restoration /mitigation plan does not target the exact replacement of the
habitat being lost through filling activities. Instead, the
restoration /mitigation plan has been designed to optimize a wide diversity
of habitats and plant communities.
This wide diversity of habitats and plant communities has
been selected to improve area utilization by anadromous
salmonids and local shellfish resources; improve local water
and air quality; provide a wide range of wildlife feeding,
nesting, and rearing areas; re- establish intertidal emergent
wetland areas presently limited within the Port Angeles
Harbor area; and provide upland plant communities that are
essentially non existent in the Port and downtown areas.
In addition, this restoration /mitigation plan also
incorporates numerous opportunities to provide and enhance
recreational and educational uses of the project area.
These opportunities can also be expanded to include elements
of the City of Port Angeles Master Plan and potential Valley
Creek Watershed planning and restoration.
The primary components of the restoration /mitigation program
are:
The creation of a wide range of intertidal and
upland areas through the excavation of fill
materials landward of the existing seawall. The
extent of such excavation will be based on the
selected plant communities, tidal habitats, and
the interchange of tidal /stream flows.
19
The removal of approximately 225 feet of the
existing seawall to allow direct connection of the
restoration /mitigation area with the open water
habitats of the harbor. This direct connection
will accommodate the interchange of tidal flows;
sediment movements; detrital drift interactions;
and the movements of fish, shellfish, and wildlife
species.
The creation of gently sloped intertidal beach
areas consisting of intertidal mudflat, low salt
marsh, high salt marsh, and upland plant
communities (Figure 3)
Intertidal mudflat
Low salt marsh
High salt marsh
Valley Creek

TOTAL CREATED 180.000 soft (4.12 acres)
The re- direction of Valley Creek into the restored
estuarine area. Such re- direction, out of the
existing culvert, will allow better access to the
upstream habitats of Valley Creek by spawning
adult salmon and trout species. Such restoration
of the direct connection of the stream to the
estuarine area will further enhance detrital
drift, sediment movements, and tidal interchanges.
Storm overflows will be directed into the old
culvert to assure no adverse impact to the
mitigation area.
The creation of an estuarine complex which
supports juvenile salmonids in their foraging for
epibenthic and benthic invertebrates and as escape
cover from predators. Such estuarine systems are
vital components to the viability of salmonid
populations providing nursery areas, abundant prey
organisms, and area for osmoregulatory changes
from the freshwater environment into the marine
environment (Figure 4).
Because of the migratory patterns of juvenile
salmonids, estuarine areas provide beneficial
habitats to both directly associated freshwater
systems and to freshwater systems far removed from
the local area.
20
Square Footage Created
18,000 sqft
32,000 sqft
38,000 sqft
16,000 sqft
76,000 sqft
The development of the stormwater overflow system
within the stream which will use the existing
culvert to by -pass the project site and assure
that winter storm event flows do not adversely
impact the estuarine system.
The development of estuarine structural features
which act to reduce the potential that wave
actions associated with winter storm events will
adversely impact the estuarine system. These
structural features will also provide a different
type of habitat useful as nesting, feeding, and
resting areas by a wide range of wildlife species.
The establishment of upland snags, trees, and
shrubs useful as nesting areas for a wide range of
wildlife species. Such habitat is presently not
available within or adjacent the project site.
Placed snags and nesting boxes will target cavity
nesting species observed in the local area. For
example, hooded merganser and bufflehead are two
such cavity nesting birds which should benefit
with increased nest location availability.
To increase the diversity and availability of
habitats, the mitigation design incorporates
increased "edge" effect. Edge or "ecotone" is the
transitional area between two habitat types.
These transition areas increase diversity and
broaden the range of available habitats.
The placement of snags and large woody debris in
the intertidal area on the project site. Such
woody debris will provide the hiding, burrowing,
and attachment points for a wide range of
intertidal wildlife, macroinvertebrates, and
plants. Such large woody debris forms the
physical habitat, increased production capability,
and food base for a number of fish, shellfish, and
wildlife prey species.
Local water quality enhancements through the
directed grading of the filled log pond area and
onsite upland log storage and sorting areas. Such
grading will allow onsite surface waters to be
directed away from the intertidal areas and into
the City's stormwater facilities. Site planning
and future upgrading of the City's road and
stormwater control systems will include water
quality improvement such as oil /water separators
or biofiltration in grassed swales.
21
Local water quality enhancement will also be
realized by the collection and treatment of waters
presently discharged into the log pond by the
onsite milling processes. Treatments may include
land farming applications or treatment within the
City's sewage treatment facilities.
Planting of the upland areas to allow screening of
adjacent land uses from the created intertidal
area. Such vegetation screening will also reduce
the adverse impact of noise and dust to the
created intertidal area and the City of Port
Angeles.
The creation of passive recreation opportunities
along the project site. These opportunities
include incorporation of onsite activities with
the City of Port Angeles Master Shoreline Plan
(Figure 5).
The creation of passive and hands on educational
opportunities within the project site. These
opportunities will include stewardship programs
for mitigation area and eventually the remainder
of the Valley Creek System.
The creation of a recycled products demonstration
area. Recycled products will be used for all
trails, signs, structures, and benches within the
upland areas of the project site.
The placement of signs to provide information
about:
Wetland /estuarine functions
Water quality protections and enhancements
Local area and Native American history
Wildlife and fish species, timing, habitat
needs, and migration.
"Do not feed the animals" and why
Control of access into the intertidal area
Who to call if you have questions
Cooperators and participators in the project
Reason for the mitigation project
The establishment of sediment bedload movement in
the lower section of Valley Creek. While present
activities will remain unchanged for now, future
watershed basin planning effort will establish
locations upstream from the intertidal area to
maintain streambed sediments.
22
The GOAL of the proposed intertidal restoration /mitigation
plan is the complete compensation of environmental impacts
associated with the filling of an industrial log pond. The
Project will created a viable interactive freshwater stream
and estuarine habitat complex within an urbanized marine
waterfront. The created habitat complex will provide the
environmental elements required to support a wide range of
fish, wildlife, and plants and will enhance the City of Port
Angeles Master Plan for waterfront recreational and
educational opportunities.
PROJECT BENEFITS
The proposed intertidal restoration /mitigation plan provides
a wide range of direct and indirect benefits. These
benefits include:
Restored and enhanced production and
transportation of estuarine detritus into the
adjacent marine environment.
Restored and enhanced required habitats, and
resulting survival during the early life history,
of marine species (i.e Dungeness crab larvae).
A diversity of estuarine and upland plant species.
Educational and stewardship opportunities fo_r
school groups and local citizen groups.
Recreation opportunities of a local and regional
nature.
PROJECT GOAL AND OBJECTIVES
Restored and enhanced anadromous species access
and utilization of the Valley Creek system.
Restored and enhanced prey production and prey
availability for juvenile salmonids during their
early out migration period from Valley Creek and
adjacent small streams.
Research opportunities for the documentation of
estuarine habitat recreation efforts.
Enhanced local water quality biofiltration.
A greater diversity of wildlife species and
habitats that support a wider range of wildlife
activities. (i.e. nesting and broodrearing).
23
Enhanced detrital and prey production from the
adjacent upland areas into the estuarine
environment.
Reduced overall project costs associated with the
disposal of excavated clean fill materials. This
project will coincide with up- grades to be
completed at the plywood mill facility designed to
improve sorting and storage of logs prior to
milling.
Reduced noise and dust within the downtown areas
of Port Angeles.
Watershed based planning activities and habitat
limiting factors analysis.
Enhanced safety for workers in the log sorting,
storage, and handling areas.
The ability to adequately screen, through fencing
and vegetation, pedestrians out of the log
sorting, storage, and handling areas.
Enhanced water dependent access to ongoing log
rafting activities.
The ability to provide a demonstration project
about the uses of recycled products. For example,
all pathways, benches, and signs used in the
upland areas will be made from recycled materials.
The placement of snags and nest boxes for wildlife
enhancements. Such locations for cavity nesting
species (ie. hooded merganser and bufflehead) do
not presently exist in the local area.
24
TYPES OF HABITATS TO BE CREATED
The proposed restoration /mitigation plan targets the
creations of a wide range of habitats presently not provided
within the Valley Creek System or within the existing log
pond proposed for filling. The plan provides tidal
elevations which begin at approximately -2.0 Mean Low Low
Water (MLLW) and extend through upland areas of
approximately +18.0 MLLW. This range of elevations was
selected to establish plant communities which will survive
under expected site conditions and salinities. For example,
the deepest area excavated (between 0.0 and -2.0 MLLW) will
provided the appropriate salinity and substrate for the
proposed planting and natural establishment of eelgrass
(Zostera marina). High salt marsh vegetation such as
Lyngby's sedge (Carex lvnabvei) and saltmarsh bulrush
(Scirnus maritimus) will be planted and expected to
naturally establish in the areas between +4.0 and +8.0 MLLW.
Following the U.S. Fish and Wildlife Services methodologies
(Cowardin, et.al., 1979) the selected habitats to be created
as a part of this restoration /mitigation plan are:
1. Marine, Intertidal, rockyshore, rubble, artificial
substrate, (M2RS2r),
2. Estuarine, Subtidal, unconsolidated bottom, sand,
(E1UB2),
3. Estuarine, Subtidal, aquatic, rooted vascular,
(E1AB3),
4. Estuarine, intertidal, unconsolidated shore,
cobble gravel, (E2US1),
5. Estuarine, intertidal, unconsolidated shore, sand,
(E2US2),
6. Estuarine, intertidal, unconsolidated shore, mud,
(E2US3),
7. Estuarine, intertidal, emergent persistent,
(E2EM1)
8. Estuarine, intertidal, streambed, sand, (E2SB2)
9. Estuarine, intertidal, aquatic bed, rooted
vascular, (E2AB3)
10. Estuarine, intertidal, aquatic bed, algal, (E2AB1)
11. Estuarine, intertidal, scrub shrub, broad leaved
deciduous, (E2SS1)
12. Riverine, tidal, stream bed, cobble gravel,
(R1SB3)
13. Riverine, tidal, stream bed, sand, (R1SB4), and
14. Upland, forested, scrub shrub, and emergent
25
FUNCTIONS OF CREATED HABITATS
While the number of habitat types may appear rather long,
this list can be consolidated into five general elements.
These primary elements are:
1. Marine,
2. Estuarine, subtidal,
3. Estuarine, intertidal,
4. Riverine, and
5. Upland
The intent of the restoration /mitigation plan is that all
general habitat types (except the upland areas) will by
inundated during normal high to extreme high tidal events.
All three of the estuarine habitat functions identified
within the Estuarine Habitat Assessment Protocol (Simenstad,
et.al.,1991) for fish and wildlife are primary components of
the selection of site design and plant communities. These
identified functions are categorized as (1) reproduction,
(2) feeding, and (3) refuge and physiological adaptation.
While additional functions apply, these three functions are
utilized to explain the primary mechanisms of estuarine
habitats (Simenstad, et.al., 1991).
The most prominent element targeted in the wide range of
created estuarine habitats is that of plant species
diversity. Proposed site elevations were established to
assure diversity of plant communities and tidal movement
food base detritus within and out of the estuarine
environment. Such a wide range supports and greatly
enhances the three primary mechanisms noted above. For
example, juvenile chum salmon use patches of intertidal
vascular plants for refuge and physiological adaptation
while also feeding on the abundance of plankton, insects,
and crustaceans. Absent such vegetation, both the feeding
and refuge components would be limited.
Because the restoration /mitigation plan has been developed
to provide habitats for a wide range of fish and wildlife
the three primary mechanisms of estuarine habitats have been
provided. Many of these primary mechanisms also overlap.
For example, juvenile mallards will feed and hide in a patch
of sedge along the high salt marsh areas at one water
elevation while juvenile coho salmon will feed and hide in
the same patch of sedge at another water elevation. In
addition, the adjacent upland vegetation provides nesting,
rearing, and cover habitats for upland birds species while
also providing a source of leaf litter for estuarine
crustaceans and fallen limbs for juvenile Dungeness crabs to
hide under.
26
Following a standard functions and value analysis as defined
in Table 1, the proposed restoration /mitigation area would
be rated as having a HIGH value.
Hydrologic support the created area would be directly
associated with open water marine environments of
the Port of Port Angeles Harbor and the freshwater
inputs of Valley Creek. A majority of this
created area would be intertidal and include areas
that would be permanently flooded.
Shoreline protection the created area would include
stands of dense woody vegetation along a fairly
significant shoreline. In addition, adjacent
shoreline areas are highly developed with either
industrial activities or City of Port Angeles
waterfront.
Stormwater and floodwater storage While more a
function of wetland areas further upstream in a
watershed; the created area is adjacent highly
urbanized and developed area. The stormwater
capacity of this created area would help to reduce
the impacts of stormwater on the marine
environment through dissipation of stream flow
energy.
Water quality The created intertidal area is located
downstream of a highly urbanized and developed
watershed. The proposed density of vegetation
will act to biofilter waterborne pollutants.
Local water quality will be improved within the
stream system and upland stormwater will be
controlled and treated as a part of the entire
project.
Natural biological function The created intertidal
area and associated uplands will be highly
vegetated with a very diverse mixture of trees,
shrubs, and emergent plant species. These plant
species have been selected because of the natural
occurrence in similar locations and tidal
elevations, and because of the fish and wildlife
habitat values. The plant communities formed
within this program will provide for the feeding,
reproduction, and refuge of several fish and
wildlife species. Unique habitat feature, which
include snag trees, old stumps, and nesting
features are also included in the plan.
The proposed restoration /mitigation plan also incorporates
several intrinsic functions and values. These include:
recreational, educational, open space, public involvement
and stewardship, and industrial area screening.
27
SOURCE OF FILL MATERIALS
The complete filling of the log pond will require
approximately 125,000 cubic yards of materials.
Approximately 54,000 cubic yards of the required materials
will be obtained from the mitigation area. The remainder of
the required fill will be obtained from nearby upland
sources. Presently identified upland areas include the
overburden from the City of Port Angeles landfill facility
and from excavations at a planned wood waste handling
facility on Port property adjacent the Port Angeles Airport.
All materials will be tested and meet Puget Sound Dredged
Disposal Analysis criteria for disposal.
LOCATION OF MITIGATION SITE
The selected location of the mitigation site is directly
east of the existing log pond and part of the same piece of
property owned, for the most part, by the Port of Port
Angeles. This selected site allows a direct connection to
the Valley Creek stream system and to the marine
environments of the Port Angeles harbor area.
A portion of the log pond and selected mitigation site are
located outside the existing harbor line. As such, these
areas are owned by the Washington State Department of
Natural Resources (DNR) and managed by the Port under
direction from DNR. Specific arrangements will be required
with DNR to allow the Port to undertake and complete
proposed activities in those areas inside the harbor line.
The proposal appears to fit within the guidelines of RCW
79.90 but final approval form DNR will be required.
ADJACENT LAND USES
The mitigation site will create a permanent separation of
the industrial areas of the Port of Port Angeles to the west
and the downtown and waterfront areas of the City of Port
Angeles to the east. The property directly east of the
mitigation site, as well as the mitigation site itself, is
presently used for log sorting and storage in connection
with the K -Ply operation.
It is the intent of the Port of Port Angeles and the City of
Port Angeles to convert the area directly east of the
mitigation site into a convention center and hotel complex.
28
The mitigation site will created much needed fish and
wildlife habitats within an urban waterfront area and has
the potential to become a focal point of local interest and
an amenity to the entire Port Angeles community.
TIMING OF PROJECT ACTIVITIES
All activities associated with the filling of the existing
log pond and the creation of the restoration /mitigation area
will be accomplished during the same time frame. One
primary factor that drives the project timing is that all
excavated materials from the mitigation area will be used in
the log pond filling process.
In addition, all project activities must coincide with the
requirement that operations associated with log sorting,
handling, storage, and milling not be adversely impacted by
project activities. The area of the mitigation site and
areas east of the mitigation site are presently used for log
storage and handling. The ongoing operations of the mill
require that these storage areas are replaced when or before
they are lost.
IMPLEMENTATION SCHEDULE
Proposed filling activities of the log pond and construction
of the mitigation area will occur in phases and are planned
to begin during the summer of 1993. Initial phases will
target the modification of the present NPDES discharges,
identification of fill materials, identification of specific
vegetation donor sites, and the modification of onsite log
handling operations.
The final project grading of both the filled pond area and
the intertidal mitigation site is proposed for June /July
1994. Upon the completion of final grading of both areas an
"AS- BUILT" survey will be completed which identified site
elevations, large organic debris and snag placements, and
unique habitat features. The as -built will be completed in
such a manner as to be duplicated in future site monitoring
phases (see mitigation monitoring). Standardized points
will be established for cross sectional analysis and
evaluation.
The as -built survey will also assist in the finalization and
any site specific modifications which may be required for
the construction planting plans. Specific elevation and
tidal associations will be a primary factor in plant
placements.
29
PHASED PLANTING SCHEDULE
The planting of the intertidal restoration /mitigation area
will occur in phases to assure plant survival and the
appropriate location of selected species. All upland areas
will be planted as soon as possible following final
construction. The proposal targets final construction to be
completed during the summer of 1994. As such, all upland
area will be planted during the fall /early winter of 1994.
The planting of the intertidal areas will be undertaken
during two time periods. Initial intertidal planting will
occur in the late winter /early spring of 1995. This first
period allow the intertidal mitigation area to begin to
stabilize following initial construction. Mitigation site
elevations may vary slightly as a result of settlement of
sediments during the first winter following construction.
Approximately 25% of the intertidal areas, as determined by
aerial coverage, will be planted during the first intertidal
planting phase.
The second intertidal planting phase will be undertaken in
the late winter /early spring of 1996. This second period
allows for continued settlement together with an evaluation
of the first planting phase. While one year between
planting phases may not be optimal, the period is believed
to provide adequate planning information about planting
densities, selected species, planting methods, and sediment
depositions which would prove beneficial for project
success.
During the second planting phase an additional 25% of the
intertidal areas will be planted. The phased intertidal
planting plan targets a total coverage of 50% of the created
surfaces. This amount of total coverage has been selected
to allow natural establishment of vascular plants and algae.
In addition, by leaving these open spaces an assessment can
be undertaken to evaluate not only the successes or failures
of this project but also direct the success of future such
projects.
EROSION CONTROLS
During construction all exposed soils will be protected as
soon as practicable in accordance with City of Port Angeles
ordinances and Best Management Practices (BMPs). This
generally includes hydroseeding, site irrigation, placement
of silt fences, and surface water management systems.
Specific erosion control plans will be included within the
final design documents.
30
MITIGATION MONITORING
Following the successful completion of the initial
intertidal restoration /mitigation construction a five year
monitoring program will be undertaken. This monitoring
program has been designed to assess the physical stability
and structure of the mitigation area, the biological
productivity and utilization of the mitigation area, and the
survival and growth of vegetation (both planted and
naturally established). This monitoring program is designed
to follow suggested methods, techniques, and objectives of
the Estuarine Habitat Assessment Protocol (Simenstad, et.al.
1991)
Monitoring of the survival and growth of vascular vegetation
(both planted and naturally established) and macroalgae
communities is also a primary elements of the program. This
monitoring will assess both intertidal and upland plant
communities. The monitoring parameters for vascular
vegetation in the intertidal areas include percent cover,
plant survival, species diversity, and shoot /stem length.
The monitoring parameters for macroalgae communities will
assess percent cover and species diversity. The monitoring
parameters for upland vegetation include percentage of
aerial cover, absolute counts of species presence and
mortality, measurement of new growth for selected indicator
species, plant vigor and vitality, presence of invader plant
species, percentage of exposed soil, and soil hydrology
(Appendix A).
Monitoring of the biological productivity and utilization of
the mitigation area will be accomplished during several
periods within the five year monitoring program. These
assessment periods will vary depending upon the elements
being evaluated and time of year. For example, assessment
of the productivity of epibenthic prey organisms within the
intertidal areas which are important as food for juvenile
salmonids will be completed during the spring of the second
and fourth years following construction completion. Fish
utilization of the intertidal area will also be completed
during epibenthic prey assessment. Direct observations of
utilization by bird and mammal species will be completed at
various time of the year to assess mating, nesting, brood
rearing, and wintering activities (Appendix B).
Monitoring of physical features will evaluate the shoreline
stability associated with the creation of intertidal areas.
The primary component of this monitoring aspect in the
survey of site topography using the established methods and
reference points identified during the completion of the as-
built site survey. Site topography will be completed once a
year during the mid- to late summer. Surficial sediment
surveys will also be completed once a year during the mid-
31
to late summer to determine the composition of sediments of
the intertidal areas of the restoration /mitigation area
(Appendix C).
ESTABLISHED THRESHOLD AND PERFORMANCE CRITERIA
The proposed intertidal restoration /mitigation plan has been
developed to optimize habitat functions which support a wide
range of fish, wildlife, shellfish, and plant communities.
These identified functions are categorized as reproduction,
feeding, and refuge and physiological adaptation.
The Port of Port ,Angeles is committed to maintaining and
assuring that the restoration /mitigation area provides the
goals and objectives identified within this document. To
determine whether these functions have been meet, the
following THRESHOLD /PERFORMANCE CRITERIA have been
established for use during onsite and post construction
monitoring and site evaluations. The intertidal
restoration /mitigation plan shall be judged to have met the
stated project goals and objectives when, at the conclusion
of the five year monitoring program, the following are found
to occur onsite:
1. The establishment of an interactive freshwater
stream and estuarine habitat complex within an
urbanized marine waterfront. The total combined
size of this mitigation area shall be 4.12 acres.
Included within this total combined size is both
upland and intertidal areas.
2. Through analysis of yearly physical beach
elevation surveys it is shown that more than 90%
of the original as -built intertidal areas continue
to be within the intertidal zone at the end of the
five year monitoring program. The initial total
amount of created area below the Ordinary High
Water Mark is designed to be 2.4 acres.
3. Through analysis of yearly physical survey it is
shown that 90% of the original as -built upland
areas continue to be above the Ordinary High Water
Mark at the end of the five year monitoring
program. The initial total amount of created area
above the Ordinary High Water Mark is designed to
be 1.73 acres.
32
4. That all upland trees and shrubs that did •not
survive the first year following initial planting
were replaced with similar species and size.
5. That 80% (by stem count) of the combined total of
all upland trees and shrubs planted during the
initial construction period are alive and
exhibiting growth at the end of the five year
monitoring period. This percentage has been
selected because the initial planting targets a
120% coverage (by stem count).
The percentage of upland vegetated canopy cover of
combined tree and shrub species will be as
follows:
1 year after planting
2 years after planting
3 years after planting
4 years after planting
5 years after planting
20 -30% minimum cover
30 -45% minimum cover
35 -50% minimum cover
40 -65% minimum cover
50 -75% minimum cover
6. That 50% of the combined total of all low and high
salt marsh vegetation planted during the initial
construction period are alive and exhibiting
growth at the end of the five year monitoring
period.
The percentage of low and high salt marsh
vegetated cover of combined species within areas
planted will be as follows:
1 year after planting
2 years after planting
3 years after planting
4 years after planting
5 years after planting
MAINTENANCE AND CONTINGENCY PLANS
10 -20% minimum cover
15 -25% minimum cover
20 -35% minimum cover
30%-50% minimum cover
45 -60% minimum cover
The Port of Port Angeles and the other local cooperators in
this project are committed to maintaining and assuring that
the restoration /mitigation area provides the goals and
objectives identified within this document. The Port of
Port Angeles shall take the lead as the responsible party to
assure that the entire proposed restoration /mitigation
program is completed and that the plan's THRESHOLD/
PERFORMANCE CRITERIA are met.
33
The Port and several local cooperators are presently
identifying additional funding mechanisms to assure
additional project element completion. At a minimum, the
Port of Port Angeles will fund all primary proposed filling,
mitigation, and monitoring programs. Additional programs
(ie. waterfront trails and recycled products demonstrations)
may be dependent upon funds provided by local cooperators or
grants.
Some of these additional programs are presently undergoing
grant application with funds available in the latter part of
1993 or early 1994. For example, the Lower Elwha S'Klallam
Tribe has submitted an application to obtain 1993 Centennial
Clean Water Grant funds to perform habitat assessments and
develop a restoration plan for streams within the Port
Angeles urban corridor. Also, the Washington State
University Cooperative Extension Service for Clallam County
has also put together a program for educational programs
within the Valley Creek System to coincide with the Ports
mitigation program. These are only two on the numerous
proposals being advanced by the local community.
As a contingency, should the proposed restoration /mitigation
plan fail to meet the THRESHOLD /PERFORMANCE CRITERIA, the
Port of Port Angeles will undertake and complete required
remedial actions. Where plant survival is the failing
component the Port will replant and assure the success of
this additional planting. Any additional plantings will be
held to the same standard of success as measured by the
threshold criteria and monitoring process. Should site
elevations be the failing component the Port will modify
site conditions to meet the desired goals. Such
modifications will also be held to the same standard of
success as measured by the threshold criteria and monitoring
process.
Remedial action plans will be developed by the Port
following consultation with the resource agencies as needed
to address identified project short coming.
MONITORING PROGRAM REPORTS
Upon the completion of each yearly observation period and
subsequent completion of the entire monitoring program the
Port of Port Angeles will produce and submit a report
detailing all observations, evaluations, site elevations,
and data to the Corps of Engineers and all interested
participating resource /permitting agencies and local groups.
Such reports will be due on January 15th for all activities
completed in the previous year.
34
Because one of the primary off shoots of this intertidal
restoration /mitigation plan is the demonstration of the
ability to recreate additional intertidal habitats within
the Port Angeles area, one very important element of the
annual and final report is a critique of methods used,
analysis techniques, plant species adaptability and
transplanting success, and the changes in fish and wildlife
utilization. This critique is intended not to cast negative
shadows on the entire process, but rather to learn from this
experience and to increase our knowledge about intertidal
habitat restoration.
PHOTOGRAPHIC DOCUMENTATION
Photographic documentation will be completed during the
initial construction phase, immediately following initial
construction, and during each site visit accomplished as
part of the vegetation and wildlife monitoring projects.
Such documentation will include random photographs of
general site features and plant growth, as well as
photographs taken at established sample plot (photo point)
locations.
Permanent locations will be established for seasonal and
annual photographic documentation, and for established
vegetation sample plots. Each permanent location will be
taken in the field by numbered and flagged rebar. Photos
taken at these permanent locations shall include a panorama
view of overlapping photo frames. In addition, photos will
also be taken of unique occurrence of observations on the
site.
Photographs will be captioned and included within the
various reports produced during the monitoring phases. All
photos will be taken using an hand held 35 mm camera with a
50 to 55 mm lens.
35
INFORMATIONAL AND PUBLIC ACCESS CONTROL SIGNS
One primary element of the mitigation project is the ability
to provide educational opportunities to a wide range of user
groups. To assist with this task a number of signs have
been identified for placement along the mitigation area.
These signs will include such educational elements as:
identification of species for observation, the biological
functions of wetlands and estuarine areas, local area and
Native American history, and why mitigation is a typical
aspect of development project.
Signs will be used to restrict public assess to intertidal
and other habitat areas and inform the public why it is not
recommended that they feed the wildlife. Furthermore, area
signs will be used to inform the viewing public who they
may contact with questions about mitigation, fish, wildlife,
water quality, or how they can get involved with habitat
restoration.
Signs will also identify the cooperators in the mitigation
project.
RESOURCE IMPACT EVENTS BEYOND THE CONTROL OF THE PORT OF
PORT ANGELES
During the construction and monitoring phases of the
proposed restoration /mitigation plan, independent events may
occur within the harbor area, the stream corridor, or within
the adjacent upland area which may adversely impact the
mitigation area. Such events may be natural or caused by
accident, emergency, or malice.
Whenever such events may occur, the Port of Port Angeles
will assess the biological and physical structure of the
shoreline to determine the impacts of the event on the newly
created intertidal shoreline habitats. Should the event
result in adverse impact, the Port of Port Angeles and the
resource agencies will determine the appropriate course of
action to be taken.

APPENDIX A:
VEGETATION PLANTING AND MONITORING PLAN
This appendix describes the proposed planting and monitoring
plan for the plant communities associated with the
intertidal restoration /mitigation program. The planned
vegetation forms the primary components of fish and wildlife
habitats within the created intertidal and upland areas.
The GOAL of the Vegetation Plan is to identify and direct
all efforts designed to establish and maintain the plant
communities located in both the intertidal and upland areas
of the proposed project site.
The conceptual planting plan has been developed based on an
analysis of proposed site features, tidal elevations, and
specific elements of the overall restoration /mitigation
plan. As such, the conceptual plan address proposed goals
rather than identifying exact locations of individual.
Specific plant location will be shown on the final
construction planting plans will be developed and presented
to the resource and permitting agencies, as well as other
interested groups during 1993. Final approval of the
construction planting plans by agency personnel will occur
prior to the actual planting of the upland areas which is
currently planned to commence in the fall /winter of 1994.
UPLAND PLANT COMMUNITIES
For purpose of the upland planting efforts, the project site
is divided into two distinct areas. The identified upland
areas along the eastern and southern boundaries of the
created intertidal area are proposed to be a part of the
City of Port Angeles Waterfront Trail System. As such,
selected native vegetation will be planted in clumps to
allow view corridors across the mitigation area. The use of
vegetation, together with informational signs, will help
maintain public access along the provided trail system.
Additional trail system amenities, such as benches and
covered viewing structures, will also be augmented by the
adjacent plant communities (see Figure 3).
The identified upland areas along the western boundary of
the created intertidal area are designed such that human
access is prohibited. The vegetation within this area will
be planted at a very dense pattern with several larger trees
(approximately 14 to 16 feet in height) planted during the
initial planting phase. In addition, several snags, stumps,
a
and root balls will be placed within the upland area to
provide habitat for wildlife (see Figure 3).
Access to the upland vegetation along the west side of the
mitigation area will be limited to required maintenance and
monitoring activities. Restriction of this access will be
provided by fencing of the adjacent log sorting /storage
yard. The vegetation along the western boundary will also
serve to screen industrial uses for the downtown area of
Port Angeles.

MONITORING METHODS
Permanent vegetation sampling plots will be located in each
planting community in areas representative of the community
being sampled. The same points will be monitored twice each
year during the five year monitoring period. Observations
and measurements will be recorded for all plant species in
order of dominance based on the relative percent cover for
each species within the vegetation strata.
Sampling of tree and shrub species will be completed in 6.6
foot radius sampling plots. A stratified random method will
be used to increase the precision of sampling data while
also maintaining the element of randomness necessary for
statistical inferences.
The evaluation of the success of the planting plan will be
based on the expected cover percentages and 80% survival
rate as established by stem count. These standards will be
applied at the times of yearly monitoring. Sample locations
will be shown on the design and "as- built" plans and will
correspond with identified photopoints. Trees and shrubs
will be visually evaluated to determine the rate of
survivorship, health, and vigor of each plant. The
categories to be used will include: live, stressed, tip die
back, basal sprouts, not found, apparently dead, and dead.
THRESHOLD CRITERIA
The following threshold criteria have been established to
assess the upland plant communities.
That 80% (by stem count) of the combined total of all
upland trees and shrubs planted during the initial
construction period are alive and exhibiting growth at
the end of the five year monitoring period. This
percentage has been selected because the initial
planting targets a 120% coverage (by stem count).
The percentage of, upland vegetated canopy cover of
combined tree and shrub species will be as follows:
1 year after planting
2 years after planting
3 years after planting
4 years after planting

INTERTIDAL PLANT COMMUNITIES
HIGH SALT MARSH PLANT COMMUNITIES
For purposes of this planting plan the created high salt
marsh area is defined by elevations generally above Mean
High High Water (MHHW). Within the Port Angeles area MHHW
has been identified at approximately the +7.5 MLLW
elevation. The high salt marsh areas are typically
inundated by tidal waters on a less than daily frequency and
are contiguous with the low upper reaches of the low salt
marsh areas.

INTERTIDAL PLANT COMMUNITIES PLANTING SCHEMES
Selected intertidal areas will be planted in two phases.
This phased approach will allow for settlement of surface
sediments following initial construction and further
refinement of site specific elevations. Phase one planting
will target the placement of selected species to cover 25%
of the total area created for both low and high salt marsh
elevations. Specific construction planting plans will be
developed following completion of the "as- built" survey at
the end of the intertidal restoration /mitigation excavation
phase.
e
Phase two planting will target the placement of selected
species to cover an additional 25% of the total area created
for both low and high salt marsh elevations. Specific
construction planting plans will be developed following the
completion of the first year's topographic survey. By
holding final design of the second planting phase until the
end of the first full year of monitoring the design will be
able to incorporate both positive and negative aspects
identified after the first years and the success of the
first year's planting efforts.
MONITORING METHODS FOR INTERTIDAL PLANT COMMUNITIES
Monitoring of the survival and growth of vascular vegetation
(both planted and naturally established) and macroalgae
communities is a primary elements of the intertidal
restoration /mitigation program. The selected monitoring
parameters for vascular vegetation within the intertidal
areas include percent cover, plant survival, species
diversity, and shoot /stem length. The monitoring parameters
for macroalgae communities will assess percent cover and
species diversity.
Percentage of cover and species occurrence will be
accomplished by visual estimation of a cover class for each
species identified within a 0.25 m sampling quadrat.
Quadrat samples will be stratified and replicated. This
smaller sample quadrat size will allow a higher number of
replications and a lower variance in identified parameters
(Simenstad, et.al. 1991).
Sampling analysis of intertidal vegetation will be completed
once during the late summer of each year of the monitoring
program.
In addition, if plants are collected from adjacent donor
sites the Port will undertake a monitoring program to assess
the impacts of plant collection on the donor plant
community. Monitoring will follow the same techniques
identified above. This monitoring will also allow
comparison of mitigation area plant community growth
patterns, percent cover, species adaptability, and survival.

APPENDIX B:
BIOLOGICAL MONITORING PLAN
This appendix describes the proposed biological monitoring
plan for the intertidal restoration /mitigation project. One
primary intent of this mitigation project is to provide a
wide range of intertidal and upland habitats favorable to
fish and wildlife populations within the Port Angeles area.
In the design of the mitigation plan, particular emphasis
was placed on tidal elevations and the planting of very
diverse plant communities. This emphasis was based on the
stated objective of the Port to restore viable salmon and
shellfish populations, as well as enhance and establish
wildlife uses within the marine waterfront environment.
The connection of the mitigation area to the Valley Creek
system further influences the desire to restore habitat
elements essential to juvenile salmonid migration and
residency within the nearshore estuarine environment. The
restoration of the Valley Creek Estuary is viewed by local
public interest groups, the Lower Elwha S'Klallam Tribe, the
Port, and the City as an essential first step in the
evaluation, basin planning efforts, and potential
restoration of all the small stream in the Port Angeles
area.
The GOAL of the Biological Monitoring Plan is to evaluate
the estuarine restoration process. Monitoring will emphasis
both an assessment of available habitats and resultant
species utilization patterns. To assist in meeting this
goal the monitoring plan targets three specific sampling
methods: epibenthic zooplankton projection, fish species
utilization of the intertidal area, and wildlife species
utilization of the entire mitigation area.
Annual reports will be formulated of all data, sampling
techniques, analysis, observations, and inferences completed
during the monitoring year. These reports will be made
available to all project participants and interested
individuals.
a
EPIBENTHIC ZOOPLANKTON SAMPLING
Epibenthic zooplankton provides a primary prey component
utilized by juvenile salmonids during their migration and
residency within the nearshore estuarine environment. The
availability of these prey organisms has been identified by
several studies to be a primary factor in the survival and
fitness of juvenile salmonids, as well as other estuarine
fish species.
Sampling Methods:
The analysis of epibenthic invertebrate colonization of the
intertidal areas of the mitigation site will be accomplished
by standardized epibenthic pump sampling techniques (Thom,
et.al. 1986) as adapted by Watershed Dynamics, Inc.
Techniques used are intended to be consistent with other
such prior and on -going epibenthic pump sampling programs
undertaken around the Puget Sound Area. Such consistency
will allow for a more accurate analysis and comparison of
epibenthic invertebrate communities at various locations.
Epibenthic pump sampling would be completed during an ebbing
tide with between 0.25 to 0.5 meters (10 to 20 inches) of
water covering the sample area. All samples will be
initially filtered in the field through a 0.14 mm sieve and
preserved at time of collection with a 10% buffered formalin
solution.
The intertidal beach will be sampled, following the
techniques noted above, on the second and fourth years
following completion of mitigation construction. Sampling
is not proposed for the first year following construction to
allow for biological and physical stabilization of the
project area.
A total of eight (8) collection sites, of three (3)
replicate samples each, will be sampled during three (3)
sample periods each year of the study. Sample periods will
be approximately four (4) weeks in separation, beginning in
early April and ending in early Junej. Epibenthic pump
collection sites will be located along the created
intertidal area at the 0.0 to +2.0 MLLW elevations.
A grid pattern will be established on the created intertidal
area to allow random sampling of epibenthic prey. This grid
pattern used will be the same pattern used to allow
vegetation sampling activities. The longitudinal and
latitudinal distance between grid intersect will be further
defined at 0.1 distances. A standard random numbers table
will be used to select the grid intersect point, the
longitudinal point, and the latitudinal point. These three
b
random numbers will identify the sample point to be used as
one replicated sample site for one of the samples periods.
The random selection process for each replicated sample site
will be completed for each sample period within a sample
year.
Epibenthic sampling methods and analysis will target those
organisms shown to be forage species used by juvenile
salmonids. While the sampling may select a preference for
salmonid species the intent is to provide habitats for a
wide range of fish species. Salmonid forage species have
undergone much more analysis and will allow comparisons with
other intertidal beach restoration projects.
The salmonid prey organisms selected for analysis area:
Harpacticoida
Haroacticus spp.
Tisbe spp.
Zaus spp.
Amphipoda Coroohium spp
Anisoaammarus spp.
Eoaammaerus spp.
Photis spp.
Aoroides spp.
Ischvroceirus spp.
Isopoda Gnorimosnhaeroma spp.
Oreaonensis spp.
Mysidacea Neomusis spp.
Tanaidacea Lepotchilis spp.
Diptera larval and pupal stages
Cumacea Cumella spp.
Statistical Testina:
All epibenthic organisms within each replicate sample will
be sorted, identified to lowest possible taxonomic level,
and enumerated. Laboratory analysis will emphasize a
statistical evaluation of site abundance and density of
preferred juvenile salmon prey organisms. A statistical
analysis of variance (ANOVA) will be completed and data
stratified by date and depth. Test will also be run to
determine if these is a statistical difference of the
stratified samples
c
A "Goodness of Fit" test will be undertaken to test the
normality of the data collected. Provided the data are
found to be normal and homoscedactic, a parametric ANOVA
test will be undertaken. To delineate where statistical
differences may have been observed through this analysis, a
multiple range test will be utilized.
Data Comparisons:
Observed epibenthic data from the mitigation site will be
compared to a wide range of other intertidal mitigation
projects within the Puget Sound area. A "Goodness of Fit"
for comparison of site data with other similar studies.
Inferences from this testing will be used to determine the
ability of the mitigation site to provide epibenthic prey
organisms.
Should time and funds be available, similar sampling will
also be completed on other small steam estuaries in the
Clallam County area. If this task is undertaken, sampling
methods, timing, and statistical analysis will be completed
in the same manner. Statistical analysis will allow
inferences to be drawn about the epibenthic productivity of
the mitigation area.
FISH SPECIES UTILIZATION
Beach seine sampling of the intertidal areas of the
mitigation area will be undertaken to assess the utilization
of this area by fish species. Sampling will be completed
once a week between the first part of April and the end of
June of the second and fourth years following the completion
of beach construction. Collected data will include: species
presence, length frequency distribution, life history
stages, and reproductive status. If possible analysis of
residence time and growth rate will also be completed.
Sample Methods:
Two (2) replicated samples will be completed each sample day
at each of eight (8) sample sites within the mitigation
area. In addition, two (2) replicated samples will also be
completed each sample day at each of three (3) sample sites
along the seawall on the harbor side adjacent the mitigation
area.
d
A floating beach seine with the dimensions of 100 feet in
length and 8 feet in depth will be used during all seining
activities. Seining will occur during flooding tides with
the seine set parallel to the beach and equally drawn to the
shoreline by attached end ropes.
All captured fish will be held in a bucket, identified to
species, measure to fork length in mm, and inspected for
significant characteristics (ie, reproductive character).
Following data collection all captured fish will be
released.
Data Inferences:
Review of the fish sampling data will allow for an analysis
of fish utilization, species abundance and diversity, and
area utilization by specific target species., Inferences
can then be drawn concerning the ability of the mitigation
area to provide habitats for fish species.
WILDLIFE SPECIES UTILIZATION
Wildlife species observations of the mitigation area will be
undertaken to assess the utilization of this area by
wildlife species. Observations will be conducted during
three sampling periods each year for a total of five years
following the completion of mitigation area construction.
Collected data will include: species presence, areas used,
activity categories, sexes, life history stages, and species
interactions. Special notations will be made on the
utilization of placed snags and large woody debris and the
activities associated with these structures.
Samole Methods:
Systematic observations will be completed using binoculars
and spotting scopes. Standard times will be established at
six (6) observation points. Onsite observation activities
will be complete three (3) sample periods a year:
April /early May, late July /August, and late
December /January.
Data Inferences:
Review of the wildlife observation data will allow for an
analysis of wildlife utilization, species abundance and
diversity, and area utilization by specific target species.
Inferences can then be drawn concerning the ability of the
mitigation area to provide habitats for wildlife species.
e
PHYSICAL MONITORING
APPENDIX C:
PHYSICAL MONITORING PROGRAM
This appendix document identifies and describes the proposed
physical monitoring program for evaluation the physical
shoreline stability and the distribution and composition of
substrates within the intertidal area.
Physical monitoring will evaluate shoreline stability and
characteristics associated with the creation of the
intertidal mitigation areas. The primary component of this
monitoring aspect is the survey of site topography using the
established standard survey techniques and methods and
reference points identified during the completion of the as-
built site survey. The initial as -built site survey will be
completed immediately following the completion of onsite
construction. The site survey will include the project area
and the area 200 -feet waterward of the present seawall in
front of the project area.
Site surveys will be completed once a year during the mid
to late summer following the completion of the as -built for
a period of five years. Each survey will be used to compare
changes in slope, acreage, and tidal elevations.
Survey information is also a vital component to the proposed
planting plan, the survival of onsite plant communities, and
the physical stability of site features. In particular,
selected plant species are identified and planted to match
tidal elevations, and the stability of created seawalls is
dependent upon the structure of the intertidal area.
SURFICIAL SEDIMENT MONITORING
Surficial sediment surveys will be completed once a year
during the mid- to late summer following the completion of
the as -built for a period of five years. These surveys will
determine the distribution and composition of surface
substrates. The sediment surveys will include the project
area and the area 200 feet waterward of the present seawall
in front of the project area.
a
Sediment surveys will be completed by following randomly
placed 1 m quadrat set by a established grid system within
the created intertidal area. The grid system (50 feet
transect line) will also be used during the vegetation
planting and monitoring program. The depth characteristics
of surface sediments will be determined by hand dug holes.
The information collected during these surveys will assist
in the evaluation of plant success, sediment movements, and
changes in site elevations.
THRESHOLD CRITERION
The intertidal restoration /mitigation project will be
considered to have met the threshold criterion from the
physical perspective and the end of the monitoring period
when:
Through analysis of yearly physical beach elevation
surveys it is shown that more than 90% of the original
as -built intertidal areas continue to be within the
intertidal zone at the end of the five year monitoring
program. The initial total amount of created area
below the Ordinary High Water Mark is designed to be
2.4 acres.
Through analysis of yearly physical survey it is shown
that 90% of the original as -built upland areas continue
to be above the Ordinary High Water Mark at the end of
the five year monitoring program. The initial total
amount of created area above the Ordinary High Water
Mark is designed to be 1.73 acres.
Should remedial action be required, such actions would be
undertaken by the Port of Port Angeles following comment and
review from the participating resource and permitting
agencies and local interest groups.
