No Net Loss Mitigation Plan i January 31, 2018 INTRODUCTION Ecological Land Services, Inc. (ELS) has been contracted by Terry Nealey to conduct a no net loss and floodplain assessment (NNL) to address potential impacts associated with a bulkhead replacement for the property at 351 Pleasant Harbor Road in Brinnon, Washington. The property consists of a residential shoreline lot, Jefferson County Tax Parcel Number 988200103, that lies in a portion of Section 10, Township 25 North, Range 2 West of the Willamette Meridian (Figure 1). The project is located within the 200 -foot shoreline jurisdiction and requires completion of the no net loss assessment to satisfy the requirements of Jefferson County Code, Title 18, Shoreline Master Program (JCCSMP). Mitigation sequencing is required to address potential impacts associate with the new bulkhead within the shoreline buffer and achieve no net loss of buffer function and habitat for the shoreline community. JEFFERSON COUNTY SHORELINE MASTER PROGRAM This project is being reviewed under the updated JCSMP that was adopted in 2015 because it is within 200 feet of the shoreline of Pleasant Harbor, part of Hood Canal. The entire property lies within 200 feet of the shoreline so it is under shoreline jurisdiction and requires mitigation sequencing to evaluate potential impacts under Jefferson County Shoreline Master Program (JCSMP). Under the current administrative process, projects proposing construction within the designated shoreline buffer and FEMA 100 year floodplain must complete a habitat survey, no net loss analysis, and floodplain assessment to document existing conditions and show that there will be no net loss of buffer function per Section 18.25 of the JCSMP. SITE DESCRIPTION The 0.17 -acre property is located on the east side of Pleasant Harbor Road in Brinnon, Jefferson County, Washington (Figure 1). The wedge-shaped property widens slightly towards the shoreline (Figure 2). The shoreline residential lot is comprised of a single-family cabin and deck that is situated on a moderate slope with stairs that access the beach situated on a steep embankment. There is a level parking area between the road and the cabin (Photoplates 1 and 2). A narrow path of paving stones on the north property line serves as shared access to the top of the shoreline bank with the adjacent property (Photoplates 2 and 3). Along the top of the shoreline bank, there is an old fence and minimal shrub vegetation (Photoplate 3). Towards the south end of the open top of bank, there is a corner of maintained lawn and a fire pit (Photoplates 4 and 5). The beach stairs begin at the top of the bank and scale the steep slope down to the shoreline (Photoplates 5 and 6). There is a shed and lean-to used for storing boats and kayaks stilted above the beach (Photoplates 6 and 8). The south half of the concrete bulkhead is intact and the north half of the shoreline bank is comprised of chunks of concrete from the old bulkhead and some debris used to prevent continued erosion (Photoplate 7). The bulkhead was damaged in a storm event. Most of the property is densely vegetated with mature fir trees and native shrubs except where shrubs have been cleared to allow access to the beach stairs. The beach was observed during low tide at the November 2017 field visit. The beach slopes gently to the water and is comprised of sand and small cobble with oyster shells and some boat wreckage. There was no aquatic vegetation observed in the debris wrack and the beach is unvegetated. Properties to the north and south have similar stairs and sheds with low concrete bulkheads (Photoplates 7 and 8). Terry Nealey — Nealey Bulkhead Replacement Ecological Land Services, Inc No Net Loss Mitigation Plan l January 31, 2018 SITE DEVELOPMENT PROPOSAL The proposal involves the repair of about 25 feet of shoreline bank for stabilization. The north half of the shoreline bank has no bulkhead and is subject to significant erosion by tides. Plastic sheet pilings will be driven into the ground about 3 feet deep and cables will anchor the pilings to the slope below ground. Filter fabric and gravel will backfill the space behind the piles to improve drainage conditions and prevent further erosion (Figure 3). The project proposes no new impacts because the property had a complete bulkhead in the past and repair is necessary to prevent issues in the future. In order to accommodate the proposal for work near the beach, the project must address potential impacts to the 150 foot shoreline buffer. The bulkhead will be located at the ordinary high water mark (OHWM). There will be no new permanent impacts to important habitat or vegetation. The addition of the new portion of bulkhead will not result in new or destructive impacts to the shoreline so therefore achieves no net loss of shoreline buffer function. ENVIRONMENTAL AND HABITAT CONDITIONS Shoreline Environment The shoreline adjacent to this lot is located along the north edge of Pleasant Harbor on the west side of Hood Canal (Figure 1). This section of shoreline is composed of a cobble beach with sand and some shell debris (Photoplate 8). Maps obtained for this project indicate the presence of patchy eelgrass to the south of the property in Pleasant Harbor (DOE 2014) (Figure 5). Estuarine wetlands are mapped within this area of the bay however, no estuarine conditions were observed on the shoreline along this section of Pleasant Harbor during the site visit. This section of shoreline is composed of developed residential properties with nearly 100 percent armoring along the OHWM consisting of bulkheads that extend down the shoreline for several hundred feet to the north and south (Photoplate 8). The bulkheads on either side of this lot are constructed of concrete (Figure 6). This bulkhead appears to have been constructed right along the OHWM. The properties to the north and south have similar shoreline slopes with boat houses and stairs upslope of the bulkheads. Both have vegetation growing on the slope that is comprised of native and non-native shrub vegetation (Figure 6). Wildlife Inventory There is no breeding habitat for Pacific sand lance (Ammodytes hexapterus) or any other forage fish mapped within the shoreline environment (WDFW 2015). There is, however, presence of oyster beds and Dungeness crab mapped within Hood Canal. Northern Spotted Owl buffer management area is mapped over the entire township, however, there are no habitat areas mapped for the shoreline adjacent to this lot. No terrestrial habitat or wildlife occurrences are mapped on this or the adjacent properties. There are no habitat features available for the federally listed endangered, threatened, or sensitive species in the vicinity of this project except for listed salmonids species, which utilize Puget Sound and Hood Canal as part of their lifecycle (USFWS/NOAA Fisheries 2015). None of the species identified during online research were observed during the site visit conducted on November 29, 2017. The shoreline environment Terry Nealey — Nealey Bulkhead Replacement No Net Loss Mitigation Plan 2 Ecological Land Services, Inc January 31, 2018 appears to be in a natural condition waterward of the bulkhead with no recent disturbances observed so provides quality habitat to the species identified within this area of the shoreline. Buffer Functions This lot lies within a shoreline residential designation and is zoned Rural -Residential, which allows 1 dwelling units per 5 acres. There is residential development to the north and south of the lot that also have boat houses and bulkheads on the beach. Because the shoreline slope is so steep, the onsite buffer function is fairly low except where native shrubs and trees are growing. The width of buffers necessary to protect a critical area from degradation is related to the functions of the critical area and the buffer itself (Castelle, et al. 1992). Buffers function to protect water quality of critical areas including shorelines by removing sediment and nutrients from runoff and the function depends on the type of soils, vegetation, and characteristics of the runoff. The function of buffers is also based on width and slope. In some cases, buffers as low as 50 feet are effective in filtering pollutants when there is dense groundcover, no slope or a gradual slope, and the runoff sheet flows across the buffer. The buffer function on this site is a result of steep topography and historic use as a residential waterfront property. The main function provided by the onsite buffer includes the ability to filter pollutants and slow the runoff generated on upslope impervious surfaces that partially reduces the degradation of the shoreline environment. Most of the runoff generated on this lot originates on level grassy terrain and appears to slowly discharge to the shoreline by infiltrating through the soil. Buffers function to limit human intrusion when there are dense vegetation communities which humans cannot penetrate. These dense vegetation communities also reduce indirect human impacts such as noise and light, which can affect shoreline areas. The value of the buffer to provide these functions is based on the condition of the shoreline and wildlife that are currently utilizing the shoreline (Sheldon, et al. 2005). The shoreline slope is too steep for access aside from the existing stairs. The buffer functions relatively well in a residential setting. IMPACT ANALYSIS Shoreline Impacts The shoreline of Pleasant Harbor will not be directly impacted by onsite construction activities because the project represents temporary impacts in an area already disturbed by human development (Photoplate 6). The bulkhead is proposed in the same location as the previous bulkhead and therefore avoids new impacts to the shoreline. There will be no impact to vegetation cover within the buffer because the work will be conducted from the beach and there is no vegetation growing at the bottom of the shoreline slope. There will be no increase in the amount of runoff generated onsite because the bulkhead is vertical and will not increase the amount of impervious surface. There will be no indirect stormwater impacts on the shoreline because the stormwater generated onsite will remain exactly the same as before. Noise generated during bulkhead construction, which will include use of equipment and workers to install the pilings, may influence use of the shoreline environment by wildlife species. This area is already developed and there is noise currently generated by the existing and adjacent homes. There will likely be an increase in noise generated during construction but once construction is Terry Nealey — Nealey Bulkhead Replacement No Net Loss Mitigation Plan Ecological Land Services, Inc 3 January 31, 2018 completed, the noise will return to current levels. Noise and light impacts are currently generated on the adjacent residential lots. Shoreline Buffer Impacts The project proposes to construct the bulkhead in the exact location of the previous bulkhead and in line with the existing concrete bulkhead, which demonstrates avoidance of additional buffer/shoreline impacts and new impacts. Because the buffer is currently very steep and vegetated with natives, increased protection will be afforded to the shoreline environment particularly with regard to habitat. The bulkhead will protect the slope from further erosion which will prevent excessive sediment and debris from impacting the shoreline. The project will only temporarily increase the amount of noise and light generated on this lot but will return to normal post - construction. The new bulkhead represents a minimal increase in impervious surface so there will be no negative impact to the shoreline buffer because the bulkhead will serve to protect the shoreline from continued erosion. Water quality onsite will not change and the new bulkhead will improve onsite drainage to encourage infiltration. The site will not generate any new pollutants or sediments that will have a negative impact on the shoreline environment. It will also not change the conditions or use of the area. HABITAT AREA DESCRIPTION The property lies on the west shore of Hood Canal and north of Pleasant Harbor (Figure 1). There is residential development along the top of the bluff beginning in Brinnon and extending south around the horn of Pleasant Harbor. The bluff is generally vegetated with native conifer trees and shrubs partially overhanging the OHWM of the shoreline in places. There are conifer trees rooted at the top of the bluff onsite, but are sheered off to maintain the view from the cabin. The bluff is nearly vertical and drops about 30 feet from the terrace on which the lawn area is situated to the shoreline below. There are mature fir trees between the top of the bluff and Pleasant Harbor Road which form a dense canopy and prevent the cabin from being seen on aerial photos. The bluff decreases in height to the north towards Brinnon. The beach slopes gradually to the water from the toe of the bluff. It is composed of gravel and sand with some cobble and boat debris. There is some evidence that the bluff has eroded in the past near the toe due to high tides. The beach is unvegetated and wrack from previous high tides was composed of woody material and needles from the fir trees. There was no eelgrass or other marine vegetation observed in the wrack. The potential presence of listed species, including fish, bird, and mammals, as well as critical habitat that have a primary association with the habitat of Hood Canal was evaluated by a site visit, aerial images, the Jefferson County Critical Areas website (Jefferson County 2017), Washington Department of Fish and Wildlife (WDFW Priority Habitats and Species website (WDFW 2017), the U.S Fish and Wildlife Service (USFWS 2017) website, the NOAA Fisheries website (NOAA 2016), and the Washington Department of Nature Resources Natural Heritage website (WDNR 2017). Terry Nealey — Nealey Bulkhead Replacement Ecological Land Services, Inc No Net Loss Mitigation Plan 4 January 31, 2018 STATE AND FEDERALLY LISTED SPECIES AND CRITICAL HABITAT Federally listed fish, bird, and mammals for Hood Canal and Jefferson County (WDFW 2017) identified using the NOAA Fisheries and USFWS websites are presented in Table 1.

State candidate species include fish and wildlife species that the Department will review for possible listing as State Endangered, Threatened, or Sensitive. A species will be considered for designation as a State Candidate if sufficient evidence suggests that its status may meet the listing criteria defined for State Endangered, Threatened, or Sensitive. 4) Washington Department of Fish and Wildlife, PHS website 5) NOAA 2015 WASHINGTON DEPARTMENT OF FISH AND WILDLIFE, PRIORITY HABITATS AND SPECIES The Washington Department of Fish and Wildlife Priority and Habitat and Species (PHS) website (WDFW 2017) identifies the presence of oyster beds, Dungeness crab, and Pandalid shrimp within this portion of Hood Canal. It also lists priority habitat for northern spotted owl and estuarine zone and wetlands along the intertidal zone, however, no estuarine wetlands were identified in this section of shoreline or within 200 feet of this property. WASHINGTON DEPARTMENT OF NATURAL RESOURCES, WATER TYPING The Washington Department of Natural Resources, Forest Practices Application Review System (FPARS) mapping website (WDNR 2016a) identifies Hood Canal as a Type S water because it is a shoreline of the state. Terry Nealey — Nealey Bulkhead Replacement Ecological Land Services, Inc No Net Loss Mitigation Plan 5 January 31, 2018 WASHINGTON DEPARTMENT OF NATURAL RESOURCES, NATURAL HERITAGE PROGRAM The Washington Department of Natural Resources, Natural Heritage Program (WDNR 2016b) identifies seven species of rare plants in Jefferson County. The property for which this assessment has been conducted is developed and maintained, which is primarily dominated by fir trees and non-native vegetation. No rare plants were identified during the field visit within the floodplain area, which comprises the very east edge of the property just upslope of the OHWM. WASHINGTON DEPARTMENT OF ECOLOGY, COASTAL ATLAS The Washington Department of Ecology (Ecology 2016b), Coastal Atlas Mapping tool does not identify any marine plant species in this section of Hood Canal. It does indicate patchy eelgrass and dunegrass fringe along the shoreline around Pleasant Harbor to the south (Figure 6). No other significant features were noted on the coastal atlas map. No kelp or seaweed accumulations were noted in the wrack or dispersed on the beach during the November 29, 2017 site visit. JEFFERSON COUNTY CRITICAL AREA AND HABITAT MAPPING The Jefferson County Critical Area Maps (JCCA) viewed through the on-line mapping website was used to identify the presence of critical areas found within and along the shores of Hood Canal (Jefferson County 2017). The tool maps the property as shoreline residential, indicates wetlands in the intertidal zone, and FEMA 100 -year floodplain (Figure 5). No estuarine or freshwater wetlands are mapped on or adjacent to the property or within Hood Canal. The floodplain area extends from the shoreline of Hood Canal to the beach just below the OWHM (Figure 4). This portion of the floodplain is composed of a gradual slope absent any vegetation (Photoplate 8). There are native trees on the slope to the west that overhanging the floodplain and the upper half of the beach slightly (Photoplates 6 and 8). The mapped floodplain extends south to Pleasant Harbor. The floodplain mapping also extends north to downtown Brinnon, which lies north of the property. RESEARCH AND SITE INVESTIGATION Fish and Whales Hood Canal is part of the Puget Sound so it provides habitat for the listed fish and aquatic mammal species appearing on Table 1. The cobble and sandy beach is un -vegetated and did not contain any vegetation, seaweed, or eelgrass accumulations (Photoplate 8). The wrack observed on the beach was composed of small woody debris and seaweed but no eelgrass was documented. Larger driftwood was observed at the highest point of the beach. The bluff is mostly vegetated with native fir trees with occasional shrub outcroppings that provide some shading of the shoreline at the toe of the bluff (Photoplates 6 and 7). However, there is minimal tree canopy to provide additional shading over the floodplain section of the shoreline. Therefore, the floodplain area of this section of shoreline provides little to the food web for the listed species. The floodplain area lacks freshwater habitat and other features that would be important in the life cycle of the listed species, except that it provides saltwater habitat for the listed fish that utilize Hood Canal. Terry Nealey — Nealey Bulkhead Replacement No Net Loss Mitigation Plan Ecological Land Services, Inc January 31, 2018 Birds Research conducted for this project shows that the property is not within habitat or management areas for marbled murrelet, streaked horned lark, and yellow -billed cuckoo (WDFW-PHS 2015; USFWS 2015). The upland along this section of Hood Canal is developed with residential homes within 100 feet of the shoreline. There are no habitat features or known habitat for the listed bird species particularly within the mapped floodplain. The trees at the top of the bluff may be utilized by local raptor species including bald eagles, but they are located outside the floodplain. Plants The Washington Department of Natural Resources, Natural Heritage Program website (WDNR 2016b) lists seven rare plant species that occur within Jefferson County. None of the listed species or suitable habitat was identified on the property during the November 2017 site visit. HABITAT NARRATIVE The habitat narrative includes a discussion of the primary constituent elements (PCEs) for the species that appear on the endangered, threatened, and sensitive list for this area of Hood Canal as they appear in the FEMA floodplain habitat assessment guidance (FEMA 2013). The PCEs include those associated with fish and mammal species utilizing Hood Canal as part of their life cycle as they would be the most likely species found in floodplain areas of saltwater shorelines. Primary Constituent Elements The primary constituent elements for the critical habitat of Puget Sound salmon and steelhead in or adjacent to Hood Canal include: • Freshwater spawning sites with water quantity and quality conditions and substrate supporting spawning incubation and larval development. • Freshwater rearing sites with: o Water quantity and floodplain connectivity to form and maintain physical habitat conditions and support juvenile growth and mobility, o Water quality and forage supporting juvenile development, o Natural cover such as shade, submerged and overhanging large wood, log jams, and beaver dams, aquatic vegetation, large rocks and boulders, side channels, and undercut banks. • Estuarine areas free of obstruction and excessive predation with o Water quality, water quantity, and salinity conditions supporting juvenile and adult physiological transitions between fresh- and saltwater, o Natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks, and boulders, side channels, o Juvenile and adult forage, including aquatic invertebrates and fishes, supporting growth and maturation. • Nearshore marine areas free of obstruction and excessive predation: o Water quality and quantity conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation, o Natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, and side channels. Terry Nealey — Nealey Bulkhead Replacement No Net Loss Mitigation Plan 7 Ecological Land Services, Inc January 31, 2018 • Offshore marine areas with water quality conditions and forage, including aquatic invertebrates and fishes supporting growth and maturation. This section of Hood Canal floodplain is composed of cobble and sandy beach at the toe of the vertical shoreline bluff. The bluff is dominated by sheered fir trees with some non-native shrubs. No stream channels are present near the property that drains on the beach or within the sloping floodplain area. The beach itself is composed of cobble and lacks vegetation with only a small amount of driftwood so provides minimal protection or feeding areas for the listed species. An assortment of larger rocks and old concrete debris are also present across the beach. Trees overhang the upper half of the beach on the properties to the immediate north and south of the property but there is very little vegetation overhanging the onsite portion of floodplain. The only available primary constituent elements available on or adjacent to this property are the nearshore and offshore marine areas. The nearshore area on this property does not have overhanging large wood, aquatic vegetation, large rocks and boulders, or side channels that would prove valuable to the listed fish species. However, the sand and cobble of the beach is likely valuable as breeding areas for sand lance, pacific herring, and surf smelt. Water Quality Portions of Hood Canal appear on the list of 303(d) waters (DOE 2017a) and there are no freshwater 303(d) waters that drain into Hood Canal within 1 mile of this property. Water Quantity The floodplain is mapped outside the east end of this property is composed of gradually sloping beach and no vegetation. There are no inputs of water from the upland in this area because of the steep bank. No freshwater streams or other waterbodies were noted within several hundred feet to the north and south of the property. Vegetation Communities and Habitat Structures The shoreline along this section of Hood Canal is composed of cobble and sand that gradually slopes down waterward from the toe of the bluff (Photoplates 6 and 8). The bluff itself is mostly dominated by sheered fir trees with occasional shrub cover (Photoplates 5, 6, and 8). The area at the top of bluff is maintained by mowing with several Douglas fir trees. Additional fir trees are scattered across the property and form a forest canopy (Photoplates 3 and 4). The fir trees and shrubs provide some shading and protection habitat at the OHWM as well as food sources (bugs, berries, and the like). There are trees and shrubs growing on the shoreline slope to the north and south of this property (Photoplates 6 and 8). Floodplain Refugia There is little floodplain refugia on this property but there is significant refugia provided by the overhanging trees and native shrub understory farther to the north of the property (Figure 6). Driftwood along this section of Hood Canal is mostly small to medium in size and accumulates at the toe of the shoreline slope (Photoplate 7). Terry Nealey — Nealey Bulkhead Replacement No Net Loss Mitigation Plan Ecological Land Services, Inc January 31, 2018 MITIGATION SEOUENCING This lot lies entirely within 200 feet of Hood Canal, which represents the only critical area on or adjacent to the property. A new bulkhead is proposed along a portion of the shoreline just outside the ordinary high water line. This repair portion of the buffer is currently composed of concrete blocks and debris remaining from patched attempts to stabilize the slope (Photoplate 7). As part of the mitigation process, projects are required to address mitigation sequencing to assess whether the project can avoid, minimize, rectify, or reduce impacts before identifying compensation or mitigation measures. Avoiding Impacts: The entire lot is within shoreline jurisdiction. The shoreline buffer covers the entire property as well and extends to Pleasant Harbor Road (Figure 2). The bulkhead is proposed in the only feasible location because it will be joined with the existing bulkhead at the toe of the steep shoreline bank. The bulkhead is designed to allow water to drain and infiltrate to avoid new erosive impacts. Work will be performed at low tide in order to avoid impacts to important marine wildlife. Impacts are temporary and the beach will return to its current state post -construction. Minimizing Impacts: The project is minimizing impacts to the shoreline buffer by proposing the new bulkhead using materials that will not leech chemicals into the water over time. The new bulkhead will represent a permanent structure in the shoreline environment, but serves to minimize the amount of debris being used to stabilize the slope by replacing chunks of concrete and plastic with plastic piles. Rectifying the Impacts: The project represents a permanent impact to the buffer within shoreline jurisdiction so cannot rectify the impacts to the affected habitats. Reducing or Eliminating the Impacts: The project cannot reduce or eliminate the impacts by preservation and maintenance. Compensating for the Impacts: The project cannot avoid, rectify, or reduce the impact to the shoreline buffer but has minimized the impact to the extent possible by proposing to replace the bulkhead in the area that was once occupied by a bulkhead. Because the project will construct a bulkhead in an area that has historically been used for the same purpose, there are no new impacts to the shoreline buffer. The shoreline slope is already heavily vegetated with native trees and shrubs with minimal cover by invasive plant species (English ivy and Himalayan blackberry). The bank is so steep that removing any vegetation will create bare soil and promote erosion. Once construction activities are completed, the shoreline buffer will return to pre -construction condition. Special Management Recommendations Management recommendations for critical areas including shorelines involve identifying measures that will preserve high quality conditions or rectify disturbed conditions that maintain or improve the function of the critical area. Buffers are one of the main management methods employed to protect the function of critical areas. In areas where buffer conditions are poor, enhancement is conducted to improve the buffer function and often enhance or improve the function of the critical area as well. Other special management recommendations are applied to aid in the preservation of special critical areas, wildlife species, and/or wildlife habitats that require additional protection Terry Nealey — Nealey Bulkhead Replacement No Net Loss Mitigation Plan Ecological Land Services, Inc January 31, 2018 measures to preserve their function and populations. They are often developed for endangered, threatened, sensitive, species of concern, rare habitat areas, etc. to preserve the critical area, habitat, or species. No special management recommendations are necessary for this project because there are no endangered, threatened, sensitive species or rare habitat areas on or in the vicinity of the lot that require special protection measures. The shoreline area represents the most important critical area adjacent to the lot and does not require special protection measures because this project will have no direct or indirect impacts on the shoreline environment. During construction activities, best management practices will be utilized to protect the shoreline environment with regard to siltation caused by exposed soils within the impacted buffer. Onsite construction activities will be conducted during the summer months to reduce the chance of rain events that could cause siltation into the downslope shoreline buffer and environment. Best management practices for siltation will include use of silt fences, hay bales, and other means to prevent movement of soil material in the critical area during all phases of the construction process. No Net Loss Assessment Because the project proposes to replace a bulkhead that was damaged by a storm event, there will be no -net -loss of buffer function of the shoreline environment. The shoreline slope is currently dominated by native shrubs and trees so there is little potential for improvement of buffer function. Construction work is the minimum necessary to continue to protect the cabin and the shoreline from erosion. Because the project will replace a damaged bulkhead, this project achieves the no net loss requirement of the JCSMP. LIMITATIONS The conclusions listed above are based on standard scientific methodology and best professional judgment. In our opinion, local, state, and federal regulatory agencies should agree with our conclusions; however, this should be considered a preliminary proposal that must be reviewed and approved in writing by the regulatory agency with jurisdiction of the project and the hearing exammer.

There are many fir trees in this area, but some shrub vegetation is being maintained to keep an open walkway to the stairs. Photo 9 was taken from the same location as Photos 7 and 8. It looks south along the top of the shoreline bank. The beach stairs begin near the middle of the east property line. On the southern corner of the bank, there is a corner of maintained lawn and a fire pit. 1157 Yd Ave., Suite 220A DATE: 12/11/17 Photoplate 3 Project Name: Nealey 4 Longview, WA 98632 DWN: LHW Bulkhead Replacement Ecological (360) 578-1371 PRJ.

The bank is extremely steep and despite having good vegetation, is eroding. Photo 17 was taken from the beach looking southwest at the shed at the bottom of the stairs. It is stilted above the bulkhead to avoid being flooded during high tides. There is a lean-to built against the shed. Photo 18 was taken from the same location as Photo 17 looking northwest at the shoreline bank. The toe of the bank is being eroded by the tides. 11573 d Ave., Suite 220A DATE: 12/11/17 Longview, WA 98632 DWN: LHW (360) 578-1371 PRJ.

Photo 19 was taken from the toe of the shoreline bank. It shows the material which makes up the broken bulkhead. There were tires, old chunks of concrete and rotten beams on the north side of the property. This portion of the slope will be repaired as part of the project. Photo 20 was taken from the same location as Photo 19. Erosion is apparent due to the piles of soil and gravel at the bottom of the bank. There is plastic and rope buried beneath the soil which may have been part of the old bulkhead. Plastic sheet pilings will support the slope upon completion of the project. Photo 21 was taken from the same location as Photos 19 and 20 looking at the shoreline bank as it continues behind the stairs and shed. The tide passes under the structures. The extent of repair will end at the bottom of the stairs. 11573 d Ave., Suite 220A DATE: 12/11/17 Photoplate 7 Project Name: Nealey \ Longview, WA 98632 (360) 578-1371 DWN: LHW PRJ.

This area is being used for boat/kayak storage. This half of the bulkhead will remain as is. The beach is composed of cobble and sand with some shell debris. There were also some boat parts scattered among the cobble. Photo 23 was taken from the concrete bulkhead looking into the lean to. It appears the tide occasionally reaches into this area, but the condition of the concrete below the lean-to is sufficient to protect the slope. Photo 24 was taken from near the southeast property corner looking west at the shoreline slope. The fir trees pictured in Photo 13 (Photoplate 5) are visible at the top of the photo. ra DATE: 12/11/17 Photoplate 8 1157 3 Ave., Suite 220A Project Name: Nealey Longview, WA 98632 DWN: LHW Bulkhead Replacement (360) 578-1371 PRJ.
