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: CITY RESPONSIBILITIES 1.

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. 3 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. 4 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). 10 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). 11 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. 12 WETLAND FUNCTION HYDROLOGIC SUPPORT SHORELINE PROTECTION STORMWATER 8 FLOODWATER STORAGE WATER QUALITY GROUNDWATER RECHARGE NATURAL BIOLOGICAL FUNCTION LOW RATING intermittently flooded hydrologically isolated wetland width 100yds from shoreline emergent or lacking vegetation undeveloped shoreline 5 acres in size remote areas 10% woody cover 5 acres in size vegetation density intermittently flooded no proximity to pollutants retains 25% runoff 5 acres in size isolated depressions temporarily saturated impermeable substrate low plant diversity low wildlife diversity habitat features lacking one vegetation community small wetland area isolated VALUE CRITERIA MEDIUM RATING HIGH RATING seasonally flooded or open water wetland width 100 -200 yds from shoreline sparse woody and dense emegent vegetation moderately developed shoreline 5 to 10 acres in size rural areas 10 30% woody cover 5 10 acres in size 50 -80% vegetation density downstream from non -point pollutants retains 25 -50% runoff 5 10 acres in size seasonally flooded moderate plant diversity two habitat types several vegetation communities intertidal or permanently flooded wetland width 200yds from shoreline dense woody vegetation highly developed shoreline 10 acres in size urdan and developable areas 30% woody cover 10 acres in size 80% vegetation density downstream from point pollutants retains 50% runoff 10 acres in size permanently inundated water depth to several feet high plant diversity three or more habitat types large wetland size moderate wetland size unique habitat features, associated with intermittent plants or animals present associated with permanent stream/ high salt marsh stream/ tidal marsh WETLAND NUMBER: TABLE I: 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 Upland area 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. 36 4 Araya,F., Ereth,M., Fontana,S., Keller,G., and Lazzar,J. 1982.

WA 98112 (206)860.1620 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. SELECTED UPLAND SPECIES Listed below are native plant species proposed within the conceptual planting plan for placement within the upland areas of the mitigation plan. Individual plants may be collected from adjacent areas or obtained as nursery stock. Western red cedar Western hemlock red alder Douglas fir big leaf maple Pacific madrone black cottonwood bitter cherry Pacific willow Hooker's willow Pacific red elderberry vine maple Oregon grape salal red huckleberry service berry Ocean spray black twinberry red osier dogwood sword fern Thu olicata Tsuaa heteroohvlla Alnus rubra Pseudotsuaa menziesii Acer macronhvllum Arbutus menziesii Ponulus trichocarna Prunus emaraenata Salix lasiandra Salix hookeriana Sambucus racemosa Acer circinatum Berberis nervosa Gaultheria shallon Vaccinium oarvifolium Amelanchler alnifolia Holodiscus discolor Lonicera involucrata Cornus stolonifera Polvstichum munitum b 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 5 years after planting c 20 -30% minimum cover 30 -45% minimum cover 35 -50% minimum cover 40 -65% minimum cover 50 -75% minimum cover 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. SELECTED HIGH SALT MARSH SPECIES Listed below are native plant species proposed in the conceptual planting plan for placement within the high salt marsh areas of the mitigation plan. Individual plants may be collected from adjacent areas or obtained as nursery stock. saltweed Lyngby's sedge big -head sedge Tufted hairgrass saltgrass seaside plantain Pacific silverweed saltmarsh bulrush LOW SALT MARSH PLANT COMMUNITIES Atriolex oatual Carex lvnabvei Carex macrocenhala Deschamnsia caesnitosa Distichlis snicata Plantaao maritima Potentilla nacifica Scirnus maritimus For purposes of this planting plan the created low salt marsh area is defined by elevations generally below Mean High High Water (MHHW). The low salt marsh areas are typically inundated by high tides on most days. The low salt marsh communities typically extend down to the approximately +2.0 MLLW level. d SELECTED LOW SALT MARSH SPECIES Listed below are native plant species proposed in the conceptual planting plan for placement within the low salt marsh areas of the mitigation plan. Individual plants may be collected from adjacent areas or obtained as nursery stock. Lyngby's sedge brass buttons fleshy jaumea pickleweed seaside arrowgrass EELGRASS PLANT COMMUNITY For purposes of this planting plan the created eelgrass planting area is defined by elevations generally below the approximately +2.0 MLLW level. Such eelgrass areas are typically inundated by all except the very lowest tidal cycles. The substrate is typically mud or mud and sand mixed. SELECTED EELGRASS SPECIES eelgrass Zostera marina Carex lvnabvei Cotula corononifolia Jaumea carnosa Salicornia virainica Trialochin maritimum Individual plants may be collected from adjacent areas or obtained as nursery stock. 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. f THRESHOLD CRITERIA The following threshold criteria have been established to assess the intertidal plant communities. That 50% of the combined total of all intertidal vegetation planted during the initial construction period are alive and exhibiting growth at the end of the five year monitoring period. The percentage of intertidal 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 MARCOALGAE ANALYSIS As a part of the analysis and sampling of the identified intertidal areas analysis will also be completed on the species and percent cover of benthic macroalgae. g 10 -20% minimum cover 15 -25% minimum cover 20 -35% minimum cover 30 -50% minimum cover 45 -60% minimum cover 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. b PROJECT SCHEDULE PERMITTING contact: Mr. Bill Conley, Port of Port Angeles 206 457 -8527 Shoreline Management Permit Issued: August 20, 1991, by City of Port Angeles.
