Replace DOCK: The new float and ramp will be constructed of galvanized steel or aluminum hardware, and yellow cedar posts, joists, decking, and trim. Sustainably harvested Alaska yellow cedar, which is insect and decay resistant, will be utilized. No pressure treated lumber will be used in this project. The new float will be fitted with polyethylene encapsulated Styrofoam® floats. The concrete footings of the float positioning pilings will be excavated to the necessary depth, using manual labor and hand tools or a small tractor, and removed completely. The new pilings holes will be approx. four feet in depth and two feet in width (4'x 2'). Replace concrete BOAT RAMP (49' by 16): The existing failed concrete boat ramp will be broken apart and removed from the site. The boat ramp's concrete containment walls, totaling approx. 73 feet in length, will be replaced with poured concreted in the existing footprint. The ramp will be topped with crushed rock (5/4") instead of concrete. Permit the existing BUOY. Repair rock and concrete BULKHEAD (66): Reinforce face with concrete. Approximately three to four feet(in width) and 49 feet length of the existing bulkhead's footing will be broken apart and removed, using a jack hammer, to provide clearance for the new face and footing. Replaced footing will be approx. four feet in depth and three feet in width (4'x T). Mitigation for the proposed project includes relocating a substantial length of the repaired bulkhead landward of the existing, which will restore approx. 64 square feet(sf) of shoreline benthic habitat, removing the float's concrete landing pad (approx. 10 sf), and installing a shoreline native planting plan.

Replace DOCK: The new float and ramp will be constructed of galvanized steel or aluminum hardware, and yellow cedar posts,joists, decking, and trim. Sustainably harvested Alaska yellow cedar, which is insect and decay resistant, will be utilized. No pressure treated lumber will be used in this project. The new float will be fitted with polyethylene encapsulated Styrofoam®floats. The concrete footings of the float positioning pilings will be excavated to the necessary depth, using manual labor and hand tools or a small tractor, and removed completely. The new pilings holes will be approx. four feet in depth and two feet in width (4'x 2'). Replace concrete BOAT RAMP (49' by 16'): The existing failed concrete boat ramp will be broken apart and removed from the site. The boat ramp's concrete containment walls, totaling approx. 73 feet in length, will be replaced with poured concreted in the existing footprint. The ramp will be topped with crushed rock (5/4") instead of concrete. Permit the existing BUOY. Repair rock and concrete BULKHEAD (66'): Reinforce face with concrete. Approximately three to four feet(in width) and 49 feet length of the existing bulkhead's footing will be broken apart and removed, using a jack hammer, to provide clearance for the new face and footing. Replaced footing will be approx. four feet in depth and three feet in width (4'x 3'). Mitigation for the proposed project includes relocating a substantial length of the repaired bulkhead landward of the existing, which will restore approx. 64 square feet(sf) of shoreline benthic habitat, removing the float's concrete landing pad (approx. 10 sf), and installing a shoreline native planting plan.

All structures are treated as new (no previous permitting for the structures). Replace dock (similar footprint and size), remove boat ramp, repair bulkhead and add inset stairs (not protruding waterward of bulkhead). Replacement of Ramp and Float: Wood components of the existing float will be disassembled using a circular saw and various hand tools. The two, concrete float positioning pilings will be sawed off at beach grade, then sawed or broken into several pieces. Following demolition, all debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to removal from the site. The concrete footings of the float positioning pilings will be excavated to the necessary depth, using manual labor and hand tools or a small tractor, and removed completely. The float landing pad will also be broken up and removed. The proposed dock will project waterward 30' from the bulkhead. The float (12' by 20') and ramp (3' by 14') will be constructed on site and will utilize galvanized steel or aluminum hardware and yellow cedar joists, decking, trim, and posts (4). In addition, the float will be fitted with polyethylene encapsulated Styrofoam®floats. A float landing constructed of yellow cedar lumber will be affixed between the float pilings. Repair the Bulkhead and Add Steps: The bulkhead's (66' long and 6' feet tall from top of bulkhead to top of footing) existing concrete footing along the western extent will be removed, as necessary, using a jack hammer, to provide clearance for the new face and footing. Following demolition, all concrete debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to removal from the site. Excavation of substrate for the bulkhead and shoreline access stairs will be done manually or using a small tractor. The footings will be approx. four feet in depth and three feet in width (4'x 3'). Concrete for the bulkhead and stairs (6.5' wide) will be poured at the same time. Demolition of the Bulkhead Footing Boat Ramp: The concrete boat ramp will be broken up and removed and returned to a natural state. Mitigation Planting: (no change) Native vegetation will be planted in a ten by twenty-foot (10' x 20') area landward of the bulkhead where vegetation is currently lacking. The author of the BE has recommended that any trees or large shrubs be installed at least ten feet (10') landward of the bulkhead, due to the potential for the roots of trees and large shrubs to damage the bulkhead, especially during summer drought conditions. At least 20 plants and five different species will be installed. Planting will occur in the fall (after the cessation of drought conditions) or in the early spring. Vegetation will be in one or two gallon pots, bare root, or harvested from the site. Within LAKE CUSHMAN and/or its associated wetlands is exempt from the requirement of substantial development because the development is categorized under WAC 173-27-040(2) as being category: H-dock Please contact Rebecca Hersha at ext 287 if you have any questions.

Mitigation for the proposed project includes relocating a substantial length of the r aired bulkhead landward of the existing, which will restore approx. 64 square feet(so o shoreline benthic habitat, removing the float's concrete landing pad (approx. 10 so, an installing a shoreline native planting plan. In addition,the proposed action will resul in a reduction of overwater coverage at the site of approx. 4 square feet. L1Background The proposed project site is located in Mason C ounty at 371 North Potlatch Drive North, Hoodsport Washington(Attachment 1). The M son County tax parcel number is 42307- 50-00018.The property is located in Section 0 Township 23N,Range 04 of the Western Meridian. The latitude is 47.49345 no h, and the longitude is -123.25148 west. The proposed project site is on Lake Cushman the Skokomish/Dosewallips Water Resource Inventory Area 16 (WRIA 16) on a sl oreline designated Urban Residential by the Shoreline Master Program of Mason Count . Lake Cushman is regulated under the Mason County Shoreline Master Program and t ie Mason County Resource Ordinance as a Fish and Wildlife Habitat Conservation Area.The Shoreline Management Act of 1971 designated Lake Cushman as a Shoreline of St ewide Significance. In addition,Lake Cushman is regulated by Tacoma Public Utiliti s(aka Tacoma Power),which has designated Shoreline Management Classificati (SMC)zones. The proposed project site is located in an SMC zone classified as"A."T oma Power defines the"A"management classification as shoreline areas with no known significant environmental/cultural resources or associated resource management als precluding existing or future shoreline uses;this classification acknowledge existing private uses and anticipates potential future private and light commercials reline uses (Kleinschmidt 2012). The proposed project site is located in a rural n ighborhood on a shoreline lot,which supports a single-family residence located appr ximately ten(10) feet vertically and forty (40) feet horizontally from the shoreline of La Cushman. Existing shoreline appurtenances(Attachments 7-12) include an prox. sixty-six-foot(66') failing concrete and rock bulkhead, an approx. forty-nine by siteen-foot(49' x 16') failed concrete boat ramp, and an approx.twenty by twelve-foot(2( ' x 12') failing, pressure-treated wood float with a thirty(30) sf(overwater coverage) ressure-treated ramp. The float rests on a concrete landing pad of approx.ten(10) squarc feet. Denis Biological Evaluation 3 1.2 Project Need and Objectives The seasonal raising and lowering of Lake Cushman has resulted in severe erosion to the footing of the bulkhead. As a result,the existing bulkhead is in danger of failing and needs to be substantially repaired. The existing ramp and float are poorly constructed and unsafe. The float's floatation is presently un-encapsulated and appears to be a source of Styrofoam®pollution. The existing concrete boat ramp had failed and is unsafe. The applicants wish to extend the life of all of their existing shoreline structures,making them safer for both humans and the environment. Therefore, the project objective is to repair or replace the existing bulkhead, boat ramp, float, and ramp while avoiding or minimizing impacts to ESA-listed species and improving shoreline habitat at the site. 2.0 Project Description As per the engineered design by P.E.Alan Tahja(Attachments 2-6),the existing, approx. 66' concrete and rock bulkhead will have the entire length of its face and failing undercut footing reinforced with concrete.Approximately three to four feet(in width) of the existing bulkhead's footing will be broken apart and removed, along approx. 49 feet of the western extent.None of the remaining 16.7' of bulkhead, along the eastern extent, will be removed. The existing failed concrete boat ramp will be broken apart and removed from the site. The boat ramp's concrete containment walls,totaling approx. 73 feet in length,will be replaced with poured concreted in the existing footprint. The ramp will be topped with crushed rock(5/4") instead of concrete. The existing float and ramp, with 274 sf of overwater coverage, will be replaced with a float and ramp,totaling 270 square feet. The new float and ramp will be constructed of galvanized steel or aluminum hardware, and yellow cedar posts,joists, decking, and trim. Sustainably harvested Alaska yellow cedar,which is insect and decay resistant,will be utilized.No pressure treated lumber will be used in this project. The new float will be fitted with polyethylene encapsulated Styrofoam® floats. A medium-sized jackhammer, a circular saw, and various hand tools will be used throughout the proposed project.All materials, equipment, debris, and workers will be transported to and from the site in cars or trucks. Geo-textile fabric will be spread over the dry lakebed before commencement of project construction in order to contain any manmade construction debris. At the completion of construction, the geo-textile fabric will be removed from the shoreline at the site, along with all construction debris and other existing manmade debris.All debris will be disposed of at a licensed landfill or other licensed disposal site. Denis Biological Evaluation 4 2.1 Project Activities Demolition of the Float Wood components of the existing float will be disassembled using a circular saw and various hand tools. The two, concrete float posi ioning pilings will be sawed off at beach grade,then sawed or broken into several pieces Following demolition, all debris will be gathered from the geo-textile fabric and placed n an appropriate disposal bin prior to removal from the site. Demolition of the Bulkhead Footing, B at Ramp, Float Pad, and Piling Footings The bulkhead's existing concrete footing along he western extent will be removed, as necessary,using a jack hammer,to provide clee rance for the new face and footing. The concrete boat ramp and float landing pad will a o be broken up and removed. The concrete footings of the float positioning piling will be excavated to the necessary depth, using manual labor and hand tools or a small tr tor, and removed completely. Following demolition, all concrete debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to removal fro n the site. Excavation of the Bulkhead Footing, th e Boat Ramp Containment Walls, & the Float Positioning Piling Holes Excavation of substrate for the bulkhead and b t ramp containment wall footings, and the two float positioning piling holes will be do ie manually or using a small tractor. The footings will be approx. four feet in depth and t iree feet in width(4'x Y). The pilings holes will be approx. four feet in depth and two feet in width(4'x 2').Excavated material will be used to fill any depressions around the wly installed footings and pilings or be removed from the shoreline at the site, as per T coma Power's rules and regulations. In the event of heavy precipitation, silt fencing(s Best Management Practices 2.5)will be utilized to contain the exposed footing trenches and stockpiled sediments. Construction of the Bulkhead FaceIFo o ting and the Boat Ramp Containment Walls Rebar will be bent to a 90 degree angle and pin ied into the existing bulkhead's lower face.Rebar will also be set horizontally along t ie footing. Rebar for the boat ramp walls will be set vertically and horizontally in the exc Fivated footings. Forms for the bulkhead and boat ramp will be constructed using lumbei, a circular saw, and other hand tools. Denis Biological Evaluation 5 Concrete for the bulkhead, boat ramp, and float pilings will be poured at the same time. Concrete will be delivered via a concrete pump truck. Before concrete is poured, two(2) 8"x 8"yellow cedar posts will be positioned in the appropriate holes.After the concrete has dried, the forms will be removed from the shoreline at the site, along with other project debris and placed in an appropriate disposal bin prior to removal from the site. Float& Ramp Construction The float and ramp will be constructed on site and will utilize the following materials: galvanized steel or aluminum hardware, and yellow cedar joists, decking,trim, and posts. In addition,the float will be fitted with polyethylene encapsulated Styrofoam®floats. A float landing constructed of yellow cedar lumber will be affixed between the float pilings. The ramp will provide access between the shoreline and float. Mitigation Planting Native vegetation will be planted in a ten by twenty-foot(10' x 20') area immediately landward of the shoreline, where vegetation is currently lacking. The exact location of the plantings and the 10' by 20' area will be at the applicants' discretion. Due to the potential for the roots of trees and large shrubs to damage the bulkhead, especially during summer drought conditions, it is recommended that any trees or large shrubs be installed at least ten feet(10') landward of the bulkhead.At least 20 plants and five different species will be installed.Planting will occur in the fall (after the cessation of drought conditions) or in the early spring. Vegetation will be in one or two gallon pots, bare root, or harvested from the site. Recommended native species include: shore pine (Pinus contorta contorta), vine maple (Acer circinatum), Pacific dogwood(Cornus nuttallii), Western yew(Taxus brevifolia), mountain hemlock(Tsuga mertensiana), evergreen huckleberry(Vaccinium ovatum), red huckleberry(Vaccinium parvifolium), mock orange (Philadelphis lewisii),Rhododendron (Rhododendron macrophyllum), Western azalea(Rhododendron occidentale), Pacific ninebark(Physocarpus capitatus), Indian plum (Oemleria cerasiformis), common snowberry(Symphoricarpos albus), snowbrush(Ceanothus velutinus var. hookeri), salal (Gaultheria shallon), Oregon-grape (Mahonia aquifolium, nervosa or repens), Thimbleberry(Rubus parviorus var.parviflorus), sword fern(Polystichum munitum), deer fern(Blechnum spicant), kinnikinnick(Arctostaphylos uva-ursi), bleeding heart (Dicentra formosa), creeping dogwood(Cornus canadensis), and wild strawberry (Frageria virginiana). Additional plant species that are native to Western Washington may be added to the above list at the applicant's discretion. Denis Biological Evaluation 6 2.2 Monitoring and Maintenance The property owners will monitor and water a native vegetation plantings as needed during dry months, until the vegetation has become established. Dead plants will be replaced throughout the monitoring period. Inv tsive, non-native vegetation will be removed or cut back as necessary. 2.3 Timing Work on the bulkhead repair and the boat ramp and float/ramp replacement will be completed over an approx. thirty(30) day peric I during daylight working hours normal to a rural neighborhood. Work will only take p ice when the water level of Lake Cushman is low,which is generally between O tober and April. 2.4 Conservation Measures 1. No construction to occur unless La Cushman's waters are low. 2. An existing bulkhead will be repair with the new face to be located approx. two feet landward of the existing foi ting along the west extent(approx. 49'). 3. No pressure treated lumber will be t sed in this project. Sustainably harvested Alaska yellow cedar, which is inseci and decay resistant,will be utilized for posts,joists, decking, and trim. 4. For the protection of marbled murre ets that may be nesting in the action area, project activities will occur between two hours after sunrise and two hours before sunset; suitable nesting habitat will not be removed. 5. Construction to take place as per th HPA provisions from the Washington Department of Fish and Wildlife. 6. Previously discussed BMPs to be strictly adhered to. 7. Native vegetation will be planted in a ten by twenty-foot(10' x 20')area immediately landward of the shoreline, where vegetation is currently lacking (see Mitigation Planting). Denis Biological Evaluation 7 2.5 Best Management Practices In order to maintain the present water quality of Lake Cushman during project construction,Best Management Practices (BMPs) will be implemented. BMPs are defined as physical, structural, and/or managerial practices that prevent or reduce the pollution of water(WDOE). The following source control BMPs,which are detailed in the WDOE's Stormwater Management Manual for Western Washington, Volume II Construction Stormwater Pollution Prevention (2012), will be implemented for long-term protection of water quality at the site: BMP C154: Concrete Washout Area Purpose:Prevent or reduce the discharge of pollutants to stormwater from concrete waste by conducting washout off-site, or performing on-site washout in a designated area to prevent pollutants from entering surface waters or ground water. Conditions of Use:Concrete washout area best management practices are implemented on construction projects where: *Concrete is used as a construction material. •It is not possible to dispose of all concrete wastewater and washout off-site (ready mix plant, etc.). •Concrete trucks,pumpers, or other concrete coated equipment are washed on-site. •Note: If less than 10 concrete trucks or pumpers need to be washed out on-site, the wash water may be disposed of in a formed area awaiting concrete or an upland disposal site where it will not contaminate surface or ground water. The upland disposal site shall be at least 50 feet from sensitive areas such as storm drains, open ditches, or water bodies, including wetlands. •A temporary washout facility shall be constructed on-site or the concrete truck will be washed out off-site. •When temporary concrete washout facilities are no longer required for the work,the hardened concrete, slurries and liquids shall be removed and properly disposed of. •Materials used to construct temporary concrete washout facilities shall be removed from the site of the work and disposed of or recycled. BMW C151: Concrete Handling Purpose: Concrete work can generate process water and slurry that contain fine particles and high pH, both of which can violate water quality standards in the receiving water. Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use this BMP to minimize and eliminate concrete, concrete process water, and concrete slurry from entering waters of the state. Conditions of Use:Any time concrete is used, utilize these management practices. Denis Biological Evaluation 8 i *Wash out concrete truck chutes, pumps, al internals into formed areas only.Assure that washout of concrete trucks is perfoi ned offsite or in designated concrete washout areas. DO not wash out concre trucks onto the ground, or into storm drains, open ditches, streets, or streams. •Return unused concrete remaining in the t ck and pump to the originating batch plant for recycling. Do not dump excess concrete on site,except in designated concrete washout areas. •Wash off hand tools including,but not lim ted to, screeds, shovels,rakes, floats, and trowels into formed areas only. •Wash equipment difficult to move in areas that do not directly drain to natural or constructed stormwater conveyances. *Do not allow washdown from areas, such s concrete aggregate driveways,to drain directly to natural or constructed stormv ater conveyances(or Puget Sound). •Contain washwater and leftover product ir a lined container when no formed areas are available. Dispose of contained con(rete in a manner that does not violate ground water or surface water quality st tndards. •Always use forms or solid barriers for con rete pours, such a pilings,within 15-feet of surface waters. BMP C101: Preserving Natural Vegetation Wherever practical, native vegetation shall be rkserved to reduce erosion. Natural vegetation should be preserved on steep slopes, near perennial and intermittent watercourses or swales, and on building sites ir wooded areas. BMP C233: Silt Fence Silt fence may be used downslope of all disturb d areas. Silt fence shall prevent soil carried by runoff water from going beneath,th ugh, or over the top of the silt fence but shall allow the water to pass through the fence. The following additional BMP shall be used o insure that water quality is not degraded during and after construction: 1. Equipment will be cleaned and checked for leaks, offsite and daily,before commencing work. In addition,the following Spill Prevention Con rol measures shall also be followed: 1) The applicant will supply the site with a portab e bathroom or allow workers access to an onsite bathroom so that solid or liquid waste w 1 not become a source of stormwater pollution. 2)The applicant will be responsible for alerting the appropriate authorities in the event of a hazardous spill. 3)The applicani will have a spill kit and be able to Denis Biological Evaluation 9 perform basic control, containment, and/or confinement operations within the capabilities of the resources and personnel protective equipment available. In other words, small spills, such as paint or oil, will be promptly and fully collected and disposed of at a suitable disposal site. In the event of a significant spill, a fish kill, and/or if fish are observed in distress the Washington State Department of Ecology(800.258.5990)and the Washington State Department of Fish and Wildlife's Area Habitat Biologist, Joshua Benton(360.602.0364), will be notified immediately. 3.0 Action Area The action area is located on the shoreline of Lake Cushman at the proposed project site. Besides the proposed project location,the action area includes the surrounding area within a designated distance from the site in order to account for construction impacts that may affect species listed under the Endangered Species Act by the U.S. Fish and Wildlife Service and the National Marine Fisheries Service as either endangered or threatened. The limits of the action area are based upon the geographic extent(in both aquatic and terrestrial environments) of the physical, chemical, and biological effects resulting from the proposed action, including direct and indirect effects, as well as effects of interrelated and interdependent activities(WSDOT 2010). Turbidity and noise are expected to be the most detrimental project effects. Because work will occur when Lake Cushman is lowered, project turbidity is expected to be no greater than turbidity that is common to the area during heavy rains, when various ephemeral and perennial streams and the north fork of the Skokomish River discharge sediment laden water into Lake Cushman. It is probable that the project's distance from the lake's lowered shoreline will be great enough that disturbed sediments will disperse gradually(via precipitation) over the exposed lakebed without ever reaching water until the lake is raised. Therefore, terrestrial noise is expected to be the most far-reaching effect from the proposed repair of the bulkhead and the replacement of the boat ramp and float at the site. The action area for terrestrial noise effects is based upon an ambient sound level of 40 dBA for an area with a population of less than 100 people per mile(WSDOT 2010). In addition,the Olympic National Forest programmatic biological assessment uses an estimated ambient level of 40 dBA for undisturbed forested areas(USDI 2003). Noise frequency and levels for the manual demolition of the concrete and rock bulkhead footing,boat ramp, float landing pad and pilings are expected to be short term and moderate, as the contractor will be using a new jackhammer that is much quieter than traditional jackhammers. In addition,the bulkhead footing and boat ramp concrete is brittle and cracking, so it is expected to break up easily.Nevertheless,the breaking of concrete by jackhammer will produce the proposed project's maximum noise level. The noise level of the jackhammer that will be used in the proposed project is 105 decibels,whereas the noise level of a traditional jackhammer is approx. 130 decibels. Therefore,the project jackhammer is 21 percent quieter than a traditional jackhammer. To determine the noise level of the jackhammer breaking up concrete at fifty feet,the Denis Biological Evaluation 10 noise levels of impact equipment were used.N ise levels at 50 feet from impact equipment, including pile drivers,jackhammer and rock drills can range from 79 to 110 dBA(WSDOT 2014). The noise level at 50 fee from a traditional jackhammer is 89 dBA (WSDOT 2014), so a traditional jackhammer b eaking up thin concrete was assigned 100 dBA. The project jackhammer will be 21 perce t quieter than a traditional jackhammer breaking concrete, so the project jackhammer eaking concrete will produce a maximum noise level of 79 dBA at fifty feet. To determine the distance that the proposed pr ect's maximum point source construction noise will travel before it attenuates to the amb nt sound level;the following Practical Spreading Loss Model equation was used: D=Do * 10((Construction Noise—Ambient ound Level in dBA)/a) Where D=the distance from the noise&Do=the reference asurement distance of 50'. Average construction noise from the proposed roject will travel approx. 3,970 feet over hard site conditions (Lake Cushman)and 1,65 feet over soft site conditions(forested areas)before it(the noise) attenuates to the aml ient sound level. Therefore,the extent of the action area is 3,970 feet or 0.75 mi. over tht lake's surface and 1,656 feet or 0.31 mi. inland from the proposed project site and adjaci nt shorelines(Attachment 1). In addition,the action area includes several un med fish-bearing streams that are located approx. approx. 0.18, 0.48, 0.87 mi.to e southeast of the site.Numerous ephemeral streams are located throughout the a tion area. 4.0 ESA Species and Habitat Information In the proposed project area,there are five spec.es listed under the Endangered Species Act by the U.S.Fish and Wildlife Service(US S)as either threatened or endangered. The bull trout(Salvelinus confluentus),marble murrelet(Brachyramphus marmoratus), northern spotted owl (Stridex occidentalis), str(aked horned lark(Eremophila alpestris strigata), and yellow-billed cuckoo(Coccyzus mericanus) are listed as threatened and critical habitat has been designated for the forrr or four species.The project area is located on Lake Cushman,which has been designated itical habitat for the bull trout. Two other species in the project area are listed as propose . The fisher(Mantes pennanti) is listed as proposed threatened, and the Dolly Varden (Sa velinus malma) is listed as proposed under the ESA "similarity of appearance"prov ion. In the proposed project area,there is one specic s listed under the Endangered Species Act by the National Marine Fisheries Service(NM S) as either threatened, endangered, or a candidate species. The Puget Sound Chinook salmon(Oncorhynchus tshawytscha) is listed as threatened and critical habitat has beer designated. Lake Cushman is a historical watershed of the Chinook that has been anthrol ogenically blocked;however, it has been designated critical habitat. Denis Biological Evaluation 11 The Washington Department of Fish and Wildlife(WDFW) GIS maps reveal the documented presence of two other species of salmonids on the State's Priority Habitat and Species list within the action area: Kokanee (Oncorhynchus nerka) and the Puget Sound/Coastal cutthroat trout(Oncorhynchus clarki clarki).The presence of these two species has been documented in Lake Cushman. WDFW data reveals that Lake Cushman was stocked with 23,896 cutthroat trout in 2005 and 205,800 Kokanee (landlocked sockeye salmon) in 2004. A WDFW biologist reported that other species that inhabit the lake include rainbow trout(Oncorhynchus mykiss) and non-native largemouth bass (Micropterus salmoides). Additionally, Tacoma Power is presently working in association with the Skokomish Tribe and the WDFW to reestablish migrating salmonid runs in the North fork of the Skokomish River. The North Fork Skokomish Powerhouse and Fish Facility has recently been completed.This facility collects adult fish at the base of Cushman Dam No. 2 and transports them to the top of the dam for sorting. It also provides sorting facilities for juvenile fish and transports them to the base of the dam for release into the river. The fry will be released in Lake Cushman, and smolts will be collected and released into the lower North Fork Skokomish River.Returning adult sockeye will eventually be collected at the base of Cushman Dam No. 2. Two new hatcheries are also under construction, one on the Hood Canal at Potlatch for sockeye,the other on Lake Kokanee for Chinook, coho, and steelhead.Hatchery construction is planned to be complete in 2015 (Tacoma Public Utilities 2015). 4.1 ESA Listed Species BULL TROUT Bull trout are members of the char subgroup of the salmon family and are native to the Pacific Northwest and western Canada. Water temperature above 15 degrees Celsius is believed to limit bull trout distribution, as eggs and juveniles require extremely cold water for survival. Bull trout are also vulnerable to degraded stream habitat, poor water quality, dams and other stream blocking structures, and predation by non-native fish. Critical habitat includes Lake Cushman and the upper North Fork of the Skokomish River(70 FR 56304). Critical Habitat in the former includes spawning and rearing habitat,while the latter provides rearing, foraging, and migration habitat, so it is expected that bull trout may be found in the action area of the proposed project site. MARBLED MURRELET A small, diving seabird in the family Alcidae,the marbled murrelet forages for small fish and invertebrates almost exclusively in nearshore marine waters, while nesting inland in old-growth or mature conifer forests. Threats include loss of habitat,predation, gill-net fishing operations, oil spills,marine pollution, and disease. The USFWS assembled a Denis Biological Evaluation 12 team of scientists in October 2011 to investigat causes for the continued decline in murrelet populations.The outcome of these dis ussions listed many factors, chiefly loss of potential nesting habitat as the main reason r hindrance of population recovery goals (WDFW 2012). Potential nest trees are coniferous trees within 5 mi (88.5 km) of marine waters that support at least one 4-inch(10.2-cm) diameter ilatform located at least 33 feet(10 meters) above the ground,with horizontal and ertical cover(USFWS 2012). If a tree or forested area does not support these habitat feal ares, it is"extremely unlikely"to support a murrelet nest(USFWS 2012).Nest success i influenced by forest structure,the spatial mix of habitat and non-habitat, human disturba ice, prey availability, and marine foraging conditions. Human disturbance can lead to higf.Fr predation levels by Steller's and gray jays, crows, ravens, and other species that seek uman-related foods and refuse at high- use recreational areas(Peery et al. 2004, Marzl iff and Neatherlin 2006). Critical habitat for the marbled murrelet,which was designated in May of 1996 and revised in October of 2011, is located within th proposed project's action area to the northwest of the project site;therefore, it must e assumed that marbled murrelets may be found nesting in the action area. State Route 11 is located between the project site, Lake Cushman, and the marbled murrelets critical h itat, so it is expected that any marbled murrelets nesting in the action area, will do so n the far side(north side) of the highway. Additionally,the proposed project will not resu t in the loss of any trees or other vegetation, and water quality at the site will be ninimally impacted. NORTHERN SPOTTED OWL The Northern Spotted Owl is one of the largestwls in North America, and the average adult female is approximately 18 inches tall wita 48-inch wingspan.Northern spotted owls are strictly nocturnal, and require old-gro h forests with multi-layered canopies of trees, including large trees with broken tops, d ormed limbs, and large holes and cavities to nest in. The Northern spotted owl is very to torial and intolerant of habitat disturbance, and a pair requires a large amount f forest for hunting and nesting. Habitat loss has occurred as a result of forest conversio i,timber harvest, fire, windthrow, insect outbreak and disease(WDFW 2012). The USFWS designated revised critical habitat for the northern spotted owl under the Endangered Species Act. In total, approximate 9,577,969 acres(ac)(3,876,064 hectares (ha)) in 11 units and 60 subunits in California, regon, and Washington fall within the boundaries of the 2 critical habitat designations The action area includes designated critical habitat for the Northern spotted owl; h ever, due to the close proximity of human habitation,it is unlikely that any North n spotted owls may be found in the action area.Additionally,the proposed project will no result in the loss of any trees or shrubs. Denis Biological Evaluation 13 STREAKED HORNED LARK Horned larks are birds that utilize wide open spaces with no trees and few or no shrubs. The streaked horned lark nests on the ground in sparsely vegetated sites dominated by grasses and shrubs. Historically this type of habitat was found in prairies in western Oregon and Washington, in dune habitats along the coast of Washington, on the sandy beaches and spits along the Columbia and Willamette Rivers, and in grasslands, estuaries, and sandy beaches in British Columbia(WDFW 2012). Today the streaked horned lark nests in a broad range of habitats, including native prairies, coastal dunes, fallow and active agricultural fields, wetland mudflats, sparsely-vegetated edges of grass fields, recently planted Christmas tree farms with extensive bare ground, moderately-to heavily- grazed pastures, gravel roads or gravel shoulders of lightly-traveled roads, airports, and dredge deposition sites in the lower Columbia River(WDFW 2012). It is expected that the action area contains unsuitable habitat for the streaked horned lark. YELLOW-BILLED CUCKOO The yellow-billed cuckoo (Coccyzus americanus) is a neotropical migrant bird that winters in South America and breeds in western North America. The yellow-billed cuckoo is insectivorous and lives in riparian woodlands (USFWS 2014). Reports of individual cuckoos have been very rare in recent decades,with only three known reports since 2000,these being near Lind(Adams Co.) in 2001, near Eureka(Walla Walla Co.) in June 2007, and from Little Pend Oreille National Wildlife Refuge (Stevens Co.) in June 2012.Habitat loss and pesticide use are thought to be two of the main causes for the precipitous decline of western yellow-billed cuckoos.Agriculture, grazing, reservoir construction, flood control, urbanization, and other factors across the West have caused the large-scale loss and degradation of lowland riparian forest,which is the cuckoo's primary habitat. It is expected that the action area contains unsuitable habitat for the yellow-billed cuckoo. CHINOOK SALMON Chinook salmon in Lake Cushman are a land-locked population that originated from anadromous fish, although loss of genetic variation makes it difficult to determine whether they are descended from historical Hood Canal populations or introduced hatchery fish(NOAA 2006). Lake Cushman Chinook are genetically different, smaller in size (and presumably less fecund)than their anadromous counterparts(Myers et al. 1998). On Jan. 12,2009,Tacoma Power,the Skokomish Tribal Nation and state and federal agencies signed a settlement agreement that resolved a$5.8 billion damages claim and long-standing disputes over the terms of a long-term license for Cushman Hydroelectric Project.Tacoma Power has proposed to introduce sockeye and spring Chinook and enhance the existing winter steelhead and coho populations in the North Fork in cooperation with the WDFW and the Skokomish Tribe(Tacoma Public Utilities 2014). In Denis Biological Evaluation 14 addition, Tacoma Power will annually release up to 100,000 rainbow trout for sport harvest(TPU 2014). Lake Cushman has been designated Critical hat itat, and the site provides rearing, foraging, and migration habitat, so it is expectei I that adult and/or juvenile Chinook salmon may be found in the action area. 5.0 Environmental Baseline Conditions 5.1 Action Area The environmental baseline represents the exis ng set of conditions,to which the effects of the proposed action are then added. The env onmental baseline is defined as"the past and present impacts of all Federal, state, and pr vate actions and other human activities in the action area,the anticipated impacts of all pr posed Federal projects in the action area that have already undergone formal or informa section 7 consultation, and the impact of state or private actions which are contemporanc Dus with the consultation process"(50 CFR 402.02). The proposed project site is in W ZIA 16 on Lake Cushman in Mason County.The majority of the fresh and marine m aterbodies in WRIA 16 suffer from water quality issues;however, Lake Cushman is not 1 sted on the state's 2012 Water Quality 303(d) list of impaired waterbodies for any par meters. Two waterbodies in the Skokomish watershed,the South Fork of the Sh okomish River and Lebar Creek are listed for the parameter of temperature(high). The proposed project site is located in a rural n ighborhood on a lot with approximately 66' of frontage on Lake Cushman, in an area cl ssified as an Urban Residential shoreline environment by the Shoreline Master Program f Mason County. Neighboring parcels support single-family residences (or recreation cabins), bulkheads,piers, and floats. Forested land in the vicinity of Lake Cushman as been logged heavily. Erosion impacts from surface flows have been particularly dam ing in the logged areas above the lake's west shore. Before the completion of two dams in 1926 anc 1930, Lake Cushman was a natural oligotrophic lake with a mean depth of 200 feel,Now Lake Cushman is 4,010-acre water body in the Olympic National Forest, having b n altered in size to accommodate the hydroelectric dams. Because of the dams,watei levels in Lake Cushman can fluctuate up to 21 meters (69 feet),with peak levels occurrij g during summer and minimum levels during winter. The magnitude of these fluctuat' ns results in periodic inundation of 12 hectares (30 acres)of land surrounding the inle to the reservoir, resulting in high water temperatures in the shallow waters of the inlet during the summer months (Brenkman 1998). Currently,the reservoir inundates 17.2 lometers (10.7 miles) of river, including areas of the original Lake Cushman (Brenkma 1998). I Denis Biological Evaluation 15 5.2 Proposed Project Area A field investigation was conducted on the afternoon of November 24th of 2015, during which the project area was surveyed visually on foot. The elevation of the lake's water level was approx. 726 feet,which is approx. 12 feet lower than the current ordinary high water mark of 738 feet. The site supports a single-family residence located approximately 10 feet vertically and 40 feet horizontally from the shoreline of Lake Cushman.The lot is moderate to heavily vegetated with native plants and supports approx. fifteen to twenty medium to medium- large conifers.The shoreline is accessed by walking past the residence and through the yard. The lake's beach is accessed via the failing concrete boat ramp. The slope of the beach is moderate in the vicinity of the bulkhead, and the substrate consists primarily of sand, gravel, clay, and cobble. There is riprap and smaller basalt rock scattered over the beach along the east side of the boat ramp. The shoreline of Lake Cushman at the site is exposed to significant fetch. Wave action has exposed the rock and concrete bulkhead's concrete footing,which appears to have been constructed rather unsubstantially without forms or subgrade placement. The existing float ramp is slippery and spans the area between the bulkhead and the float. The float rests on a failing concrete pad. One-man(approx.)angular rock and concrete debris appears to have been placed in front of the float pad and tucked beneath the bulkhead's failing toe in order to alleviate erosion. The beach was littered with dead fir needles.No fish, invertebrates, or macroalgae were observed. 6.0 Effects of the Action 6.1 Direct Effects Direct effects to the shoreline include: 1)Loss of benthic habitat from the repair of the existing bulkhead,the two float positioning pilings, and the boat ramp. 2)Creation of shade from the replacement ramp and float. 3)No contamination to Lake Cushman from the leaching of wood preservatives. 4)The prevention of Styrofoam®pollution. 5) The alteration of shoreline drift by the boat ramp. 1)As per the engineered design by P.E.Alan Tahja(Attachments 2-7),the existing, approx. 66' concrete and rock bulkhead will be partially removed and have the entire length of its failing face and footing reinforced with new concrete.The footprint of the repaired bulkhead's face and footing will be located approx.two feet landward of the existing bulkhead's toe, while the new footing will be approx. one-foot landward but subgrade, along approx.49' of the bulkhead's western extent.At the eastern extent,the proposed repair of approx. 17' of existing bulkhead will be located approx.two feet Denis Biological Evaluation 16 I waterward of the existing bulkhead's face. The footprint of the entire replacement footing will be installed subgrade,to a depth of three f ct, where the footprint of the existing, poorly constructed footing was never installed. rhe new footing and face repair will occupy approx. 132 sf of benthic habitat. By m ving approx. 49' of the bulkhead landward and 17' waterward, a total of 64 sf o enthic habitat will be restored. Each float positioning post(with a concrete base)wi occupy approx. four sf, so the two posts will occupy eight square feet. However,the are of the posts (approx. 0.45 sf for each post,totaling 0.90 sf)will constitute the only 1 t surface area, as the concrete bases for each piling will be covered by the lake's(botto ) substrate. The replacement boat ramp will be constructed in the same 545 sf footprint as the original;however,the new ramp will have 18"concrete containment walls toppe I with 1.25"crushed rock(gravel) instead of a concrete lid. In addition, concrete debris t at is scattered over the upper beach, occupying benthic habitat,will be removed froi ri the site. Due to the seasonal fluctuations of the lake's w iter level, it is probable that benthic species do not thrive in the nearshore areas of e lake that lack permanent water.No empirical evidence was found to document if b th terrestrial and aquatic species utilize the upper shoreline habitat, or if it has been too altered to support normal concentrations of either species. 2)Another direct effect is the creation of shade rom the replacement ramp and float. The overwater structures at the site produce a reduc ion in light to the underlying aquatic environment by creating a light/dark boundary hat may give piscivorous species an advantage over their prey. The use of over-wat structures in western Washington waters by bass, a common,non-native predator of juv ile salmonids, has been documented by several authors. Largemouth bass in Lake Was ington prefer areas of heavy log and brush cover over other habitat types; however, hey are commonly found under docks in early spring and are thought to be present until ate summer(Stein 1970). Substrate type typically determines the acceptability of an are for bass spawning, but adjacent cover and structural complexity are also necessary fo protection while the fish are concentrated in shallow water(Stein 1970; Cooper and Cro er 1979; Helfman 1981b; Pflug and Pauley 1984). The substrate type in the vicinity of the bulkhead and landing is gravel, cobble, and rock. Largemouth bass prefer mod ate to dense vegetation and silt or sand substrate, and nests are constructed at depths from 0.6 to 1.5 meters, in vegetated areas with soft sediment or gravel substrate on modej ate to steep slopes(Pflug 1981). The project site possesses unsuitable habitat for bas , so it is doubtful that the proposed float repair will increase the concentration of bass at the site or the occurrence of juvenile salmonid predation by bass.The project site supports no existing macrophyte vegetation and has no potential to support macrophyte veg 1tation, due to the lake's (anthropogenic) seasonal water fluctuations. In addition, White 11975) determined that phytoplankton primary production is not significantly reduced by narrow residential piers, due to the presence of more optimal light conditions than 7ound in surface wvaters,where light intensities are higher than those in which algae hrive. Data suggests that other fish species, including salmonids, are also attracted to the shade produced by over-water structures, so it is poss ble that adult salmonids could prey on Denis Biological Evaluation 17 juveniles at the site.However, researchers have indicated that structural complexity can moderate predator-prey interactions by providing more refuges for prey species as well as reducing the foraging efficiency of the predator(Cooper and Crowder 1979). This moderation may apply to naturally occurring structural habitat complexity, as well as habitat complexity due to the presence of docks,piers, boathouses and associated pilings (WDFW, WDOE, WSDOT 2001). Shade can also affect migrating salmonids. It is not known whether over-water structures disrupt the migration of salmonids in lakes.Numerous studies suggest that docks,piers, and floats attract fish, and that the attraction of fish is linked to shade produced by the object not tactile stimulus. While the effects of shade on migrating juvenile salmonids in lakes is unknown, it is also unclear in marine waters, and there is no empirical evidence of mortality. The significance of predation to migrating populations has never been empirically assessed(Simenstad et al. 1999).No studies have examined mortality due to predation much less that mortality is attributable to overwater structures(Nightingale & Simenstad 2001). As previously noted,the proposed project will result in a negligible reduction of overwater structure coverage at the site from 244 to 240 square feet. However,the existing float and the shoreline beneath it lack water for approx. six to seven months each year. In conclusion, shade created by the proposed project is expected to have discountable and insignificant direct effects on ESA listed salmonids that may be in the action area. 3)The leaching of wood preservatives is a common contaminant-related issue with the construction of shoreline SFR appurtenances. As previously note, no pressure treated lumber will be used in this project. Sustainably harvested Alaska yellow cedar,which is insect and decay resistant,will be utilized for posts,joists, decking, and trim. 4)The proposed replacement of the float's exposed Styrofoam®float material with polyethylene encapsulated Styrofoam® floats is expected to prevent the structure from becoming an eventual source of pollution to Lake Cushman. Expanded polystyrene foam (EPS), commonly known by the trade name of as Styrofoam® is pervasive in the marine environment(CWAC 2008). Polystyrene is made from petroleum and is not biodegradable. Polystyrene is a principle component of urban litter and marine debris, and it is detrimental to wildlife that ingests it(Harvard University 2008). Polystyrene is lightweight and floats. It eventually breaks down into smaller and smaller pieces that fish and other wildlife mistake for food and consume. The lifetime of plastics in the marine environment is unknown. Some researchers feel that the composition of conventional petroleum-based plastics as durable polymers means they will degrade to increasingly smaller sizes but never disappear(CWAC 2008). In conclusion,the replacement of the existing un-encapsulated float material with encapsulated floats is expected to have a beneficial impact. Denis Biological Evaluation 18 I 5)The existing and replacement boat ramp is a roin that has the potential to alter shoreline drift patterns at the site. On a natural ake, movement of woody debris and sediments would likely be important habitat pr esses; however, Lake Cushman,which is not a natural lake, lacks water along a signifi ant portion of its shorelines for approx. six to seven months each year.Additionally,th lake's shoreline is predominantly steep and cobbled as fine sediments are carried to dei per waters by wave action. While large woody debris is removed from Lake Cushman y Tacoma Power, small woody debris is such a prominent feature on the lake's shorelin s that it is doubtful a boat ramp impedes its movement.Also, natural lakes in the area ha ve large conifers along their shorelines that sometimes fall perpendicularly into the wal er, creating natural groins. Temporary Direct Effects Temporary direct effects caused by the propose project include: 1)Turbidity and sedimentation in Lake Cushman. 2)Noise. 3) Water pollution from incidental release of fuel, oil, or other contaminants. 1)Disturbed substrate from the installation f the replacement footing and steps may result in increased turbidity and sedimej tation.As previously discussed, BMPs will be strictly adhered to during constri ction in order to maintain the present water quality of Lake Cushman and pre ent runoff and pollution. In addition,the proposed project will take place when tl,e water level in the lake is much lower than the OHWM(738'), so it is probabl that rainfall will slowly disperse any disturbed substrate before it comes into Jirect contact with the lake's waters. Therefore, it is expected that turbidity a kd sedimentation will be minimal. 2)The main source of construction noise w 11 be from the jackhammering of the concrete and rock bulkhead and the con rete boat ramp.Noise will be intermittent and is expected to be a maximum of 79 JBA at 50 feet. 3)Potential water pollution from accidental release of fuel, oil, or other contaminants is another possible temporary direct eff t.As previously discussed, Spill Prevention Control measures and BMP shall be implemented during the proposed project. 6.2 Primary Constituent Element PRIMARY CONSTITUENT ELEMENTS In order to properly analyze the effects on desil nated critical habitat, a logical framework must be utilized. In determining what areas are ritical habitat, agency regulations require the NMFS to focus on the principal biological r physical constituent elements that are Denis Biological Evaluation 19 essential to the conservation of the species. The regulations identify Primary Constituent elements(PCEs)as including, but not limited to: "roost sites, nesting grounds, spawning sites, feeding sites, seasonal wetland or dryland, water quality or quantity, host species or plant pollinator, geological formation, vegetation type,tide, and specific soil types(69 FR 71888)." In 2003 NMFS biologists developed a list of PCEs specific to salmon, based on a decision matrix(NMFS, 1996)that describes general parameters and characteristics of most of the essential features under consideration when critical habitat is designated. There are six specific types of sites essential to support one or more life stages of an ESU (sites for spawning,rearing,migration, and foraging).Each site names physical or biological features (PCEs) essential to the conservation of salmonids. In 2010,USFWS biologists developed a list of PCEs specific to bull trout, based on a decision matrix (NMFS, 1996)that describes general parameters and characteristics of most of the essential features under consideration when critical habitat is designated. Lakes and reservoirs figure prominently in meeting the life-cycle requirements of adfluvial bull trout. Lake Cushman is designated critical habitat for the bull trout and the Chinook salmon; therefore,the direct effects on the designated critical habitat of bull trout and Chinook salmon have been analyzed using the appropriate PCEs for the nearshore lacustrine environment. BULL TROUT PCEs: Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 degrees F but are found more frequently in temperatures ranging from 36 to 59 degrees F--the project will have no direct effect on water temperatures that support bull trout use. Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows— the project will have no direct effect on migratory corridors that support bull trout use. Passage will not be altered during construction as no construction will occur unless the waters of Lake Cushman are low. An abundant food base including terrestrial organisms of riparian origin, and aquatic macroinvertebrates—the project is expected to have a minimal direct effect on an abundant food base for bull trout. Construction will take place when the lake's waters are lowered and approx. 49' of the repaired bulkhead will move landward, returning approx. 64 sf to benthic shoreline habitat. Permanent water of sufficient quantity and quality such that normal reproduction, growth, and survival are not inhibited--the project is expected to have a minimal direct effect on water quality. Project construction is unlikely to cause temporary turbidity or sedimentation as work will occur when the lake's waters have been lowered. BMPs are expected to prevent or moderate potential water pollution during construction.No Denis Biological Evaluation 20 pressure treated lumber will be used, and un-en apsulated Styrofoam® float material that is a potential source of water pollution will be r placed with encapsulated floats. CHINOOK SALMON PCEs: Unobstructed passage—passage will not be alt red during construction as no construction will occur unless the waters of Lal e Cushman are low. Water Quality—project construction is unlikel to cause temporary turbidity or sedimentation.BMPs are expected to prevent o moderate potential water pollution during construction.No pressure treated lumbei will be used, and un-encapsulated Styrofoam® float material that is a potential soi irce of water pollution will be replaced with encapsulated floats. Water Quantity—the project will have no effe on water quantity. Forage—approx. 49' of the repaired bulkhead will move landward,returning approx. 64 sf to benthic shoreline habitat. Natural Cover—the project will have no direct effect on natural cover. 6.3 Direct Effects to ESA Listed Species The direct effect from the proposed project to c her ESA listed species that are likely to be found in the action area have been analyzed ks follows: NORTHERN SPOTTED OWL Due to the close proximity of human habitatio and the small size of the action area, it is unlikely that any Northern spotted owls may b found in the action area of the proposed project site. However,the absence of spotted o is in the action area is not a certainty. While proposed project construction may occu between March lst and September 30th, which is the nesting season of Northern spotted owls,the following noise threshold guidelines will be followed to ensure minimal isturbance during project construction: •The proposed project will not remove dis rsal habitat and will be at least 0.25 mi. (for noise-generating activities besides I ilasting) from northern spotted owl suitable habitat(nesting, roosting, fora ng:NRF). Note: The rural neighborhood where the site is ocated extends approx. 1.5 mi. south of the proposed project site, 0.10 mi. north to Stat Route 119, and 0.15 mi. northwest. Beyond the northwest boundary of the neighbo hood, SR 119 is located less than 0.08 mi. Denis Biological Evaluation 21 from the shoreline of Lake Cushman for approx.three miles,heading toward the Staircase recreation area. With the extensive acreage of undeveloped forest land nearby, it seems unlikely that Northern spotted owls will be nesting, roosting, or foraging in the vicinity of anthropogenic development. MARBLED MURRELET The primary threats to marbled murrelet from anthropogenic activities include loss of nesting habitat, gill-net fishing operations, oil spills, and marine pollution.Previously noted BMPs and Spill Prevention Control Measures will be adhered to during project construction to protect the water quality of Lake Cushman.Noise impacts to any nesting or foraging murrelets in the action area are expected to be negligible, although construction may occur during the marbled murrelet nesting season between April 1 through September 23rd. To ensure minimal disturbance to any marbled murrelets that may be nesting in the action area, the following noise threshold guidelines will be followed during project construction: *Project activities will occur between two hours after sunrise and two hours before sunset. *Suitable nesting habitat will not be removed. Note: The rural neighborhood where the site is located extends approx. 1.5 mi. south of the proposed project site, 0.10 mi. north to State Route 119, and 0.15 mi. northwest. Beyond the northwest boundary of the neighborhood, SR 119 is located less than 0.08 mi. from the shoreline of Lake Cushman for approx.three miles, heading toward the Staircase recreation area. With the extensive acreage of undeveloped forest land nearby, it seems unlikely that marbled murrelet will be nesting,roosting, or foraging in the vicinity of anthropogenic development. 6.4 Indirect Effects Indirect effects are those effects that are caused by or will result from the proposed action and are later in time, but are still reasonably certain to occur(50 CFR 402.02). Possible indirect effects from the proposed project include: 1)The loss of shoreline aquatic vegetation. 2)The repaired bulkhead and boat ramp exacerbate passive erosion to the shoreline. 3)The repaired bulkhead causes a reduction in the accumulation of large drift logs on the beach. 4)The replacement boat ramp and float result in an increased motorized boat presence at the site. 5)Crushed rock(gravel)topping the boat ramp is scattered over the beach by wave action. 1) The replacement ramp and float will cause a reduction in light to the underlying aquatic environment,which can have significant impacts on the health and productivity of both native and non-native macrophytes and algae. Macrophytes and algae are the Denis Biological Evaluation 22 foundation for most freshwater food webs and leir presence or absence affects many higher trophic levels (NMFS 2004). It is expec d that the impact of the lake's fluctuating water level on littoral productivity will oversha low the impacts of shading from the pier and float at the site. The reduction in overwatei coverage at the site of approx. four sf is expected to be insignificant. 2) When waves reflect off shoreline armoring s ructures, particularly concrete or other types of flat-faced bulkheads,they can causes uring and hardening of the substrate and steepening of the beach. The sediment in front f a bulkhead will gradually become coarser as wave action and littoral drift remove i the finer sediment and there is no sediment available for replenishment because i is impounded behind the bulkhead (Macdonald et al. 1994). Hard-armored bulkhe ds cut off sediment that was once available to feed the beach,thus adversely affe ting natural beach-forming processes. The shoreline at the site is already unnaturally cep due to the lake's manmade origin. Accordingly,the steepness has caused significa at scouring and erosion, as there is no shallow foreshore to diminish the energy from ricoming wind waves. Any beach feeding sediments are carried away to deeper water.Th proposed repaired/replacement structures are not expected to minimize scouri and steepening of the beach.A small amount of excavated sediments will be utilized in the project to fill in holes or depressions after the bulkhead footing forms ar removed, but the majority(of excavated sediments)will be removed from the shoreline ollowing the project's completion, as Tacoma Power does not allow excavated sedi nts to be spread over the shoreline at Lake Cushman. Referenced materials for this report primarily a sess bulkhead impacts to marine shorelines and, in particular, Puget Sound. Whi e some impacts are applicable to lake shorelines,beach feeding/forming processes Alear to differ significantly and be site specific. On Lake Cushman, a lake whose shor lines lack water for roughly six months each year, it seems counterproductive to consi r beach feeding a positive habitat process as the lake was significantly enlarged to accom odate two hydroelectric dams (that produce environmentally friendly electric pow free of carbon emissions). 3) Shoreline armoring can also limit the accum dation of large drift logs on the beach, as large woody debris is less likely to accumulate n beaches that have steepened due to the presence of a bulkhead(Macdonald et al. 1994 . Large woody debris(LWD)provides detrital input, food sources, and potential refug for migrating juvenile salmon. Due to the moderate number of power boats that utilizi the lake in the vicinity of the proposed project site, it is not safe to recommend anchor ng LWD to the beach.Nor is it allowed by Tacoma Power.In addition,there are nume us existing stumps along the shoreline throughout the lake. 4)The replacement boat ramp and float may re ult in an increased motorized boat presence in the area. Fuel spills from powerbo s can contaminate water quality and potentially affect listed salmonids directly or in Erectly through their prey source(NMFS 2005). Powerboats also create amplified wave iction that can erode the shoreline, and Denis Biological Evaluation 23 prop scouring can erode benthic habitat, although benthic habitat in the littoral zone is already significantly marginalized by the lake's fluctuating water levels. Powerboats also provide some oxygenation of surface waters, although the extent is probably negligible at best. Overall,the indirect effects of powerboat usage on Lake Cushman is likely insignificant due to the lake's large size,the small number of boats that access the remote lake, and the short boating season(primarily May thru September). 5) Crushed rock(gravel)topping the boat ramp could be scattered over the beach by wave action. The project engineer believes that large (1.25") angular gravel is heavy enough to be contained by the walls of the boat ramp. It is expected that the property owner will have to replace an unknown quantity of gravel each year. 6.5 Primary Constituent Elements PRIMARY CONSTITUENT ELEMENTS The indirect effects on the designated critical habitat of Bull trout and Puget Sound Chinook have been analyzed using the appropriate PCEs for the nearshore lacustrine environment. BULL TROUT PCEs: Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 degrees F but are found more frequently in temperatures ranging from 36 to 59 degrees F--the project will have no indirect effect on water temperatures that support bull trout use. Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows—the project will have no indirect effect on migratory corridors that support bull trout use. An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish--mitigation plantings may eventually provide leaf matter and insects for aquatic life in Lake Cushman, improving foraging opportunities for bull trout. Permanent water of sufficient quantity and quality such that normal reproduction, growth, and survival are not inhibited—the use of yellow cedar(rather than pressure treated lumber)and encapsulated float material are expected to improve water quality. Denis Biological Evaluation 24 CHINOOK SALMON PCEs: Unobstructed passage—the project will not hale any indirect effect on unobstructed passage. Water Quality—the project will benefit water fality(see bull trout). Water Quantity—the project will not have any Indirect effect on water quantity. Forage—mitigation plantings may eventually I rovide leaf matter and insects for aquatic life in Lake Cushman, improving foraging opp unities for Chinook. Natural Cover—the project will not have any i t direct effect on natural cover. 6.6 Indirect Effects to ESA Listed Species The indirect effects from the proposed project t other ESA listed species that are likely to be found in the action area have been analyz d as follows: NOR THERN SPO TTED OWL & MA RBLED MURRELET While it is highly unlikely that either species w uld nest in trees that are located in a rural neighborhood,the proposed project may result in increased recreational usage at the site, which could prompt both species to nest elsew ere. 6.7Interrelated/Interdependent Iffects Interrelated and interdependent effects are desc ibed as the effects of the action under consultation analyzed together with the effects f other activities that are interrelated to, or interdependent with,that action. An interrel ed activity is an activity that is part of the proposed action and depends on the proposed tion for its justification. An interdependent activity is an activity that has n independent utility apart from the action under consultation(FWS &NMFS 1998). The roject will have no obvious interrelated or interdependent effects. Denis Biological Evaluation 25 6.8 Primary Constituent Elements BULL TROUT PCEs: Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 degrees F but are found more frequently in temperatures ranging from 36 to 59 degrees F--the project will have no interrelated or interdependent effects on water temperatures that support bull trout use. Migratory corridors with minimal physical, biological, or water quality impediments between spawning,rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows—the project will have no interrelated or interdependent effects on migratory corridors that support bull trout use. An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish--the project will have no interrelated or interdependent effects on the bull trout's food base. Permanent water of sufficient quantity and quality such that normal reproduction, growth, and survival are not inhibited--the project will have no interrelated or interdependent effects on water supply or quality. CHINOOK SALMON PCEs: Unobstructed passage—the project will have no interrelated or interdependent effects on unobstructed passage. Water Quality—the project will have no interrelated or interdependent effects on unobstructed passage. Water Quantity the project will have no interrelated or interdependent effects on water quantity. Forage the project will have no interrelated or interdependent effects on water quantity. Natural Cover—the project will have no interrelated or interdependent effects on natural cover. 6.9 Cumulative Effects Cumulative effects are defined as"those effects of future state or private activities, not involving Federal activities,that are reasonably certain to occur within the action area of the action subject to consultation"(50 CFR 402.02). Cumulative impacts are difficult to Denis Biological Evaluation 26 access. Continued growth and urbanization is li cely to detrimentally impact fish and wildlife resources. Global warming could raise he water level of Puget Sound, leaving many waterfront properties underwater. Global warming could also result in warmer water temperatures,to the detriment of species uch as bull trout. Additionally, over- fishing may deplete stocks of salmon, even as r storation of habitat in the watershed furthers their likelihood of survival. 7.0 Conclusion 7.1 Take Analysis Section 9 of the ESA prohibits take of endangei ed or threatened species, "take"being defined in Section 3 as to harass, harm,pursue, hunt, shoot, wound,trap, capture, or collect listed species, or attempt to engage in a such conduct. "Harm" is further defined as a significant habitat modification or degrada o tt n that actually kills or injures listed species by"significantly impairing behavioral erns such as breeding, spawning, rearing,migrating, feeding, and sheltering"(50 FR 222.102). "Harass" is further defined as an intentional or negligent act whic creates the likelihood of injury to wildlife by annoying it to such an extent as to significa ly disrupt normal behavior patterns which include,but are not limited to, breeding, eeding, or sheltering(50 CFR 17.3). In regards to the proposed project and the existin development activities, it is extremely unlikely that any"take"will occur.Previously isted conservation measures will further insure the likelihood that no"take"will occur. 7.2 Determination of Effect A determination of May affect, not likely to adi vrsely affect is the appropriate conclusion when effects on the species or their critical hab tat are expected to be beneficial, discountable, or insignificant. After reviewing I he appropriate data and survey information, I have concluded that the proposed project will have an insignificant impact on the previously discussed Endangered or Thr atened species if the previously discussed conservation measures are implemented. In my most honest and professional opinion, while the proposed project may impact individi al Endangered or Threatened species in the project area, it is not likely to adversely aff ct or jeopardize the continued existence of those species or their designated Critical Ha itat. The determination of effect for each of the listed species is: 1. Bull trout and their designated Critical abitat May affect, not likely to adversely affect. 2. Chinook salmon--May affect, not likely o adversely affect. 3. Marbled murrelet May affect, not like to adversely affect. 4. Northern spotted owl No effect. Denis Biological Evaluation 27 5. Streaked horned lark---No effect. 6. Yellow-billed cuckoo—No effect.

Background The Magnuson Fishery Conservation and Man ement Act was signed into law on April 13, 1976. Under provisions of the Act, eight R gional Fishery Management Councils were established to prepare FMP's in conform ce with national standards published in 50 CFR Part 600.305-340. The Magnuson Act as renamed the Magnuson-Stevens Act in a 1996 appropriations bill. On October 11, 1 96,the Sustainable Fisheries Act, which amended the Magnuson-Stevens Act,was sign d into law. Provisions included a mandate that the Councils amend each FMP to include description of Essential Fish Habitat, including adverse impacts on EFH and consery tion measures to protect EFH. Essential Fish Habitat is defined as those waters and sub ate necessary to fish for spawning, breeding, feeding, or growth to maturity. The Pacific Fisheries Management Council has designated EFH for federally-managed species on the Pacific West Coast, including 82 species of groundfish, 5 coastal pelagic species, and 3 species of salmon. The followin species may occur in Lake Cushman during some period of their life history: Chinoc k salmon(Oncorhynchus tshawytscha) and Coho salmon(Oncorhynchus kisutch). B. Essential Fish Habitat The designated EFH for Pacific salmon species is identified using U.S. Geological Survey(USGS)hydrologic units as well as hab tat association tables and life history descriptions of each life stage(PFMC 1999). T ie EFH for the Pacific coast salmon fishery is defined as those waters and substrate riecessary for salmon production needed to support a long-term sustainable salmon fish y and salmon contributions to a healthy ecosystem(WSDOT 2014). To achieve that le 1 of production, EFH must include all those streams, lakes, ponds, wetlands, and oche currently viable water bodies and most of the habitat historically accessible to salmon i n Washington, Oregon, Idaho, and California(WSDOT 2014). This does not inclu le habitats above the impassible barriers identified by the Pacific Fishery Management ouncil Fishery Management Plan(PFMC 1999). Denis Biological Evaluation 45 C. Proposed Action The proposed project is the footing repair(using poured concrete) of an existing failing rock and mortor bulkhead and the repair/reconfiguration of an existing pier and float on Lake Cushman. The action will result in a reduction of overwater coverage at the site of approx. 460 square feet. D. Effects of the Proposed Action The effects of the proposed project on designated EFH are expected to be comparable to the effects described in the attached BE. E. Conservation Measures The conservation measures and BMPs discussed in the attached BE will be implemented to minimize any adverse effects to Essential Fish Habitat. F. Conclusion The proposed project is likely to have no significant impact on designated EFH for Pacific salmon. G. References NOAA, 2006.

It is a requirement of residential and recreational dock, pier, ramp,floats that there be grating in the overwater structures as per WAC 220-660-140. We noticed that in the provided DNS that there is no mention proposed grating for the new structure. The WDFW would like to emphasize that within the WAC 220-660-140(3)(c)(iv)(B) it states the following: "Northeast/southwest, northwest/southeast and east/west oriented piers(23 to 157 degrees, 203 to 337 degrees) must have at least fifty percent of the entiredeck surface covered in functional grating regardless of width.The grating must be installed parallel o the width of the pier, evenly spaced along p the entire length of the pier."The current pier, ram and fI at structure is in a northeast/south-west orientation. It is our concern that the shading from the structure will be detrimental to the nearshore habitat within Lake Cushman. Please contact me at(360)602-0364 to discuss any questions you might have.

The proposed action is the repair of an existing concrete and rock bul ad, including the addition of inset concrete shoreline access stairs, and the repair/r configuration of an existing float and ramp. Mitigation for the proposed project inclu s relocating a substantial length of the repaired bulkhead landward of the existing, and emoving a concrete boat ramp and the existing float's concrete landing pad,which will restore approximately(approx.) 64, 784, and 10 square feet(sf) of benthic lakebed habit , respectively, for a total restoration of 858 square feet. A native planting plan will also be installed on the shoreline at the site. In addition,the proposed action will result in a ipduction of overwater coverage at the site of approx. 4 square feet. L1Background The proposed project site is located in Mason C unty at 371 North Potlatch Drive North, Hoodsport Washington (Attachment 1). The ME son County tax parcel number is 42307- 50-00018. The property is located in Section 07 Township 23N, Range 04 of the Western Meridian. The latitude is 47.49345 no , and the longitude is -123.25148 west. The proposed project site is on Lake Cushman i i the Skokomish/Dosewallips Water Resource Inventory Area 16 (WRIA 16) on a s reline designated Urban Residential by the Shoreline Master Program of Mason Count Lake Cushman is regulated under the Mason County Shoreline Master Program and t e Mason County Resource Ordinance as a Fish and Wildlife Habitat Conservation Area. rhe Shoreline Management Act of 1971 designated Lake Cushman as a Shoreline of Sta ewide Significance. In addition, Lake Cushman is regulated by Tacoma Public Utiliti (aka Tacoma Power),which has designated Shoreline Management Classificatio (SMC)zones. The proposed project site is located in an SMC zone classified as "A." T oma Power defines the "A"management classification as shoreline areas with no known ignificant environmental/cultural resources or associated resource management g, ials precluding existing or future shoreline uses;this classification acknowledges xisting private uses and anticipates potential future private and light commercial sh reline uses (Kleinschmidt 2012). The proposed project site is located in a rural n ighborhood on a shoreline lot,which supports a single-family residence located appr ximately ten (10) feet vertically and forty (40) feet horizontally from the shoreline of Lak Cushman. Existing shoreline appurtenances (Attachments 7-12) include an a prox. sixty-six-foot(66')failing concrete and rock bulkhead, an approx. forty-nine by si een-foot(49' x 16') failed concrete boat ramp, and an approx.twenty by twelve-foot(2( x 12')failing,pressure-treated wood float with a thirty(30) sf(overwater coverage) ressure-treated ramp. The float rests on a concrete landing pad of approx.ten(10) square feet. Denis Biological Evaluation 3 1.2 Project Need and Objectives The seasonal raising and lowering of Lake Cus an in conjunction with wave action from prevailing winds has resulted in severe er ion to the footing of the bulkhead. As a result,the existing bulkhead is in danger of fail' g and needs to be substantially repaired. The existing ramp and float are poorly construc d and unsafe. The float's floatation is presently un-encapsulated and appears to be a s urce of Styrofoam®pollution. The existing concrete boat ramp had failed and is un afe. The applicants wish to extend the life of all of their existing shoreline structures, r iaking them safer for both humans and the environment. Therefore,the project objectiv, is to repair,replace, and remove the existing bulkhead, float, and boat ramp while aN Diding or minimizing impacts to ESA- listed species and improving shoreline habitat al the site. 2.0 Project Description As per the engineered design by P.E. Alan Tahj (Attachments 2-6),the existing,approx. 66' concrete and rock bulkhead will have the er ire length of its face and failing undercut footing reinforced with concrete.Approximately three to four feet(in width)of the existing bulkhead's footing will be broken apari and removed, along approx. 49 feet of the western extent.None of the remaining 16.7' of bulkhead, along the eastern extent, will be removed. The existing failed concrete boat ramp will be oken apart and removed from the site. The boat ramp,which,before failing, functione I as the site's only safe access to the shoreline,will be replaced with a set of concret steps, inset into the bulkhead at the same location as the boat ramp. The steps will be ap ox. six feet(6')wide and fill the gap in the bulkhead created by the removal of the boa ramp, allowing safe shoreline access for the applicants. The existing float and ramp,with 274 sf of ovei water coverage,will be replaced with a float and ramp,totaling 270 square feet. The nex float and ramp will be constructed of galvanized steel or aluminum hardware, and ye low cedar posts,joists, decking, and trim. Sustainably harvested Alaska yellow cedar, wh h is insect and decay resistant,will be utilized.No pressure treated lumber will be use I in this project. The new float will be fitted with polyethylene encapsulated Styrofoa ®floats. A medium-sized jackhammer, a circular saw, a d various hand tools will be used throughout the proposed project. All materials, quipment, debris, and workers will be transported to and from the site in cars or truck . Geo-textile fabric will be spread over the dry lakebed before commencement of proj e t construction in order to contain any manmade construction debris. At the completic ri of construction,the geo-textile fabric will be removed from the shoreline at the site, long with all construction debris and Denis Biological Evaluation 4 other existing manmade debris. All debris will b disposed of at a licensed landfill or other licensed disposal site. 2.1 Project Activities Demolition of the Float Wood components of the existing float will be d.sassembled using a circular saw and various hand tools. The two, concrete float posit oning pilings will be sawed off at beach grade,then sawed or broken into several pieces. Following demolition, all debris will be gathered from the geo-textile fabric and placed 'i an appropriate disposal bin prior to removal from the site. Demolition of the Bulkhead Footing, B at Ramp, Float Pad, and Piling Footings The bulkhead's existing concrete footing along he western extent will be removed, as necessary, using a jack hammer,to provide clea ance for the new face and footing. The concrete boat ramp and float landing pad will a o be broken up and removed. The concrete footings of the float positioning piling will be excavated to the necessary depth, using manual labor and hand tools or a small tr ,tor, and removed completely. Following demolition, all concrete debris will be gathered rom the geo-textile fabric and placed in an appropriate disposal bin prior to removal fro the site. Excavation of the Bulkhead Footing, Shoreline Access Stairs, & Float Positioning Piling Holes Excavation of substrate for the bulkhead and sh reline access stairs, and the two float positioning piling holes will be done manually ar using a small tractor. The footings will be approx. four feet in depth and three feet in w dth (4'x 3'). The pilings holes will be approx. four feet in depth and two feet in width 4'x 2'). Excavated material will be used to fill any depressions around the newly installe I footings and pilings or be removed from the shoreline at the site, as per Tacoma Po mer's rules and regulations. In the event of heavy precipitation, silt fencing(see Best M agement Practices 2.5)will be utilized to contain the exposed footing trenches and sto kpiled sediments. Denis Biological Evaluation 5 Construction of the Bulkhead Face/Foo ing and Shoreline Access Stairs Rebar will be bent to a 90 degree angle and pin d into the existing bulkhead's lower face. Rebar will also be set horizontally along t footing. Rebar for the shoreline access stairs will be set vertically and horizontally in t excavated footings.Forms for the bulkhead and stairs will be constructed using lu ber, a circular saw, and other hand tools. Concrete for the bulkhead, stairs, and float pilin s will be poured at the same time. Concrete will be delivered via a concrete pump ruck. Before concrete is poured,two (2) 8"x 8"yellow cedar posts will be positioned in he appropriate holes. After the concrete has dried,the forms will be removed from the sl oreline at the site, along with other project debris and placed in an appropriate disp sal bin prior to removal from the site. Float & Ramp Construction The float and ramp will be constructed on site a id will utilize the following materials: galvanized steel or aluminum hardware, and yet ow cedar joists, decking,trim, and posts. In addition,the float will be fitted with polyeth3 lene encapsulated Styrofoam®floats. A float landing constructed of yellow cedar lumb will be affixed between the float pilings. The ramp will provide access between the shorc line and float. Mitigation Planting Native vegetation will be planted in a ten by tw my-foot(10' x 20') area immediately landward of the shoreline,where vegetation is c irrently lacking. The exact location of the plantings and the 10' by 20' area will be at the plicants' discretion. Due to the potential for the roots of trees and large shrubs to damag the bulkhead, especially during summer drought conditions, it is recommended that any rees or large shrubs be installed at least ten feet(10') landward of the bulkhead. At leas 20 plants and five different species will be installed. Planting will occur in the fall (aftei the cessation of drought conditions) or in the early spring. Vegetation will be in one or gallon pots,bare root, or harvested from the site. Recommended native species include: shore pi (Pious contorta contorta),vine maple (Ater circinatum),Pacific dogwood(Corms n tallii), Western yew(Taxus brevifolia), mountain hemlock(Tsuga mertensiana), ever gr en huckleberry(Vaccinium ovatum),red huckleberry(Vaccinium parvifolium), mock or ge (Philadelphis lewisii),Rhododendron (Rhododendron macrophyllum), Western azale (Rhododendron occidentale), Pacific ninebark(Physocarpus capitatus), Indian plum 10emleria cerasiformis), common snowberry(Symphoricarpos albus), snowbrush Ceanothus velutinus var. hookeri), salal (Gaultheria shallon), Oregon-grape(Mahonia i quifolium, nervosa or repens), Thimbleberry(Rubus parviflorus var.parviflor ), sword fern (Polystichum munitum), Denis Biological Evaluation 6 deer fern(Blechnum spicant), kinnikinnick(Arci staphylos uva-ursi),bleeding heart (Dicentra formosa), creeping dogwood (Corpus c nadensis), and wild strawberry (Frageria,virginiana). Additional plant species that are native to Weste Washington may be added to the above list at the applicant's discretion. 2.2 Monitoring and Maintenance The property owners will monitor and water an native vegetation plantings as needed during dry months, until the vegetation has beco ne established. Dead plants will be replaced throughout the monitoring period. Inv ive,non-native vegetation will be removed or cut back as necessary. 2.3 Timing Work on the bulkhead repair and the boat ramp nd float/ramp replacement will be completed over an approx. thirty(30) day perio during daylight working hours normal to a rural neighborhood. Work will only take pl ce when the water level of Lake Cushman is low,which is generally between O Ober and April. 2.4 Conservation Measures 1. No construction to occur unless Laki Cushman's waters are low. 2. An existing bulkhead will be repaire I with the new face to be located approx. two feet landward of the existing foLing along the west extent(approx. 49'). 3. No pressure treated lumber will be ed in this project. Sustainably harvested Alaska yellow cedar, which is insect and decay resistant,will be utilized for posts,joists, decking, and trim. 4. For the protection of marbled murre is that may be nesting in the action area, project activities will occur between two hours after sunrise and two hours before sunset; suitable nesting habit t will not be removed. 5. Construction to take place as per the HPA provisions from the Washington Department of Fish and Wildlife. 6. Previously discussed BMPs to be sti ictly adhered to. Denis Biological Evaluation 7 i 7. Native vegetation will be planted in E ten by twenty-foot(10' x 20') area immediately landward of the shorelir D,where vegetation is currently lacking (see Mitigation Planting). 2.5 Best Management Practices In order to maintain the present water quality of Lake Cushman during project construction,Best Management Practices (BMP )will be implemented. BMPs are defined as physical, structural, and/or managed practices that prevent or reduce the pollution of water(WDOE). The following sou e control BMPs,which are detailed in the WDOE's Stormwater Management Manual r Western Washington, Volume H Construction Stormwater Pollution Prevention 012),will be implemented for long-term protection of water quality at the site: BMP C154: Concrete Washout Area Purpose:Prevent or reduce the discharge of pol utants to stormwater from concrete waste by conducting washout off-site, or performing c i-site washout in a designated area to prevent pollutants from entering surface waters r ground water. Conditions of Use: Concrete washout area best anagement practices are implemented on construction projects where: *Concrete is used as a construction material •It is not possible to dispose of all concrete vastewater and washout off-site(ready mix plant, etc.). *Concrete trucks,pumpers, or other concre coated equipment are washed on-site. *Note: If less than 10 concrete trucks or pur ipers need to be washed out on-site,the wash water may be disposed of in a fo ed area awaiting concrete or an upland disposal site where it will not contamin e surface or ground water. The upland disposal site shall be at least 50 feet fro sensitive areas such as storm drains, open ditches, or water bodies, including wetlands. •A temporary washout facility shall be construLed on-site or the concrete truck will be washed out off-site. •When temporary concrete washout facilities Eire no longer required for the work,the hardened concrete, slurries and liquids shall be removed and properly disposed of. *Materials used to construct temporary concr to washout facilities shall be removed from the site of the work and disposed of or rec ycled. BMP C151: Concrete Handling Denis Biological Evaluation 8 P Purpose: Concrete work can generate process w ter and slurry that contain fine particles and high pH, both of which can violate water qu lity standards in the receiving water. Concrete spillage or concrete discharge to surfa waters of the State is prohibited. Use this BMP to minimize and eliminate concrete, cc ncrete process water, and concrete slurry from entering waters of the state. Conditions of Use:Any time concrete is used,u 'lize these management practices. *Wash out concrete truck chutes,pumps,an internals into formed areas only. Assure that washout of concrete trucks is perfon ied offsite or in designated concrete washout areas. DO not wash out concret trucks onto the ground, or into storm drains, open ditches, streets, or streams. •Return unused concrete remaining in the tri ck and pump to the originating batch plant for recycling. Do not dump excess oncrete on site, except in designated concrete washout areas. *Wash off hand tools including,but not limi ed to, screeds, shovels, rakes, floats, and trowels into formed areas only. •Wash equipment difficult to move in areas hat do not directly drain to natural or constructed stormwater conveyances. •Do not allow washdown from areas, such concrete aggregate driveways, to drain directly to natural or constructed storm ter conveyances (or Puget Sound). •Contain washwater and leftover product in lined container when no formed areas are available. Dispose of contained conc ete in a manner that does not violate ground water or surface water quality stE ticlards. *Always use forms or solid barriers for conc rete pours, such a pilings,within 15-feet of surface waters. BMP C101: Preserving Natural Vegetation Wherever practical, native vegetation shall be p tearerved to reduce erosion.Natural vegetation should be preserved on steep slopes, perennial and intermittent watercourses or swales, and on building sites inooded areas. BMP C233: Silt Fence I Silt fence may be used downslope of all disturbed areas. Silt fence shall prevent soil carried by runoff water from going beneath,thr ugh, or over the top of the silt fence but shall allow the water to pass through the fence. The following additional BMP shall be used to insure that water quality is not degraded during and after construction: Denis Biological Evaluation 9 1. Equipment will be cleaned and checked f leaks, offsite and daily, bef ore commencing work. In addition,the following Spill Prevention Contrc I measures shall also be followed: 1) The applicant will supply the site with a portable athroom or allow workers access to an onsite bathroom so that solid or liquid waste will iot become a source of stormwater pollution. 2)The applicant will be responsible f alerting the appropriate authorities in the event of a hazardous spill. 3) The applicant ill have a spill kit and be able to perform basic control, containment, and/or confir oment operations within the capabilities of the resources and personnel protective equipm nt available. In other words, small spills, such as paint or oil,will be promptly and f illy collected and disposed of at a suitable disposal site. In the event of a significant spill, a fish kill, and/or if fish are observed in distress the Washington State Depart nent of Ecology(800.258.5990) and the Washington State Department of Fish and Wildli e's Area Habitat Biologist, Joshua Benton (360.602.0364),will be notified immedia ely. 3.0 Action Area The action area is located on the shoreline of La Cushman at the proposed project site. Besides the proposed project location,the action irea includes the surrounding area within a designated distance from the site in ord to account for construction impacts that may affect species listed under the Endanget d Species Act by the U.S. Fish and Wildlife Service and the National Marine Fisher s Service as either endangered or threatened. The limits of the action area are base upon the geographic extent(in both aquatic and terrestrial environments)of the phys al, chemical, and biological effects resulting from the proposed action, including dir ct and indirect effects, as well as effects of interrelated and interdependent activities (WS OT 2010). Turbidity and noise are expected to be the most detrimental project effec s. Because work will occur when Lake Cushman is lowered,project turbidity is expectei I to be no greater than turbidity that is common to the area during heavy rains, when va-ious ephemeral and perennial streams and the north fork of the Skokomish River discharge sediment laden water into Lake Cushman. It is probable that the project's distaric o from the lake's lowered shoreline will be great enough that disturbed sediments will di erse gradually(via precipitation) over the exposed lakebed without ever reaching watei until the lake is raised. Therefore, terrestrial noise is expected to be the most far-re Ching effect from the proposed repair of the bulkhead and the replacement of the boat ra p and float at the site. The action area for terrestrial noise effects is ba d upon an ambient sound level of 40 dBA for an area with a population of less than 1 0 people per mile (WSDOT 2010). In addition,the Olympic National Forest program atic biological assessment uses an estimated ambient level of 40 dBA for undistur d forested areas (USDI 2003).Noise frequency and levels for the manual demolition f the concrete and rock bulkhead footing,boat ramp, float landing pad and piling are expected to be short term and moderate, as the contractor will be using a new ' ckhammer that is much quieter than Denis Biological Evaluation 10 traditional jackhammers. In addition,the bulkhea footing and boat ramp concrete is brittle and cracking, so it is expected to break up asily.Nevertheless,the breaking of concrete by jackhammer will produce the proposi d project's maximum noise level. The noise level of the jackhammer that will be u din the proposed project is 105 decibels,whereas the noise level of a traditional ckhammer is approx. 130 decibels. Therefore, the project jackhammer is 21 percent uieter than a traditional jackhammer. To determine the noise level of the jackhammer I reaking up concrete at fifty feet, the noise levels of impact equipment were used.Noi e levels at 50 feet from impact equipment, including pile drivers,jackhammers, trid rock drills can range from 79 to 110 dBA (WSDOT 2014). The noise level at 50 feet om a traditional jackhammer is 89 dBA (WSDOT 2014), so a traditional jackhammer bre iking up thin concrete was assigned 100 dBA. The project jackhammer will be 21 percent quieter than a traditional jackhammer breaking concrete, so the project jackhammer brc aking concrete will produce a maximum noise level of 79 dBA at fifty feet. To determine the distance that the proposed proj ct's maximum point source construction noise will travel before it attenuates to the ambie it sound level; the following Practical Spreading Loss Model equation was used: D=Do * 10((Construction Noise—Ambient S and Level in dBA)/a) Where D=the distance from the noise &Do=the reference me isurement distance of 50'. Average construction noise from the proposed pi Dject will travel approx. 3,970 feet over hard site conditions(Lake Cushman) and 1,656 et over soft site conditions (forested areas)before it(the noise) attenuates to the amb'-Int sound level. Therefore,the extent of the action area is 3,970 feet or 0.75 mi. over the ake's surface and 1,656 feet or 0.31 mi. inland from the proposed project site and adjacei t shorelines (Attachment 1). In addition,the action area includes several unnz med fish-bearing streams that are located approx. approx. 0.18, 0.48, 0.87 mi.to tf e southeast of the site.Numerous ephemeral streams are located throughout the ac ion area. 4.0 ESA Species and Habitat Info mation In the proposed project area,there are five species listed under the Endangered Species Act by the U.S. Fish and Wildlife Service (USF S)as either threatened or endangered. The bull trout(Salvelinus confluentus), marbled urrelet(Brachyramphus marmoratus), northern spotted owl (Stridex occidentalis), stre ed horned lark(Eremophila alpestris strigata), and yellow-billed cuckoo (Coccyzus a ericanus)are listed as threatened and critical habitat has been designated for the form r four species. The project area is located on Lake Cushman,which has been designated c itical habitat for the bull trout. Two other species in the project area are listed as proposed The fisher(Martes pennanti) is listed as Denis Biological Evaluation 11 proposed threatened, and the Dolly Varden (Salvin ' us malma) is listed as proposed under the ESA "similarity of appearance" provis In the proposed project area,there is one speciesed under the Endangered Species Act by the National Marine Fisheries Service (NMFSs either threatened, endangered, or a candidate species. The Puget Sound Chinook saln (Oncorhynchus tshawytscha) is listed as threatened and critical habitat has been ignated. Lake Cushman is a historical watershed of the Chinook that has been anthropog nically blocked;however, it has been designated critical habitat. The Washington Department of Fish and Wildlife (WDFW) GIS maps reveal the documented presence of two other species of salniDnids on the State's Priority Habitat and Species list within the action area: Kokanee ( ncorhynchus nerka) and the Puget Sound/Coastal cutthroat trout(Oncorhynchus cla i clarki).The presence of these two species has been documented in Lake Cushman. DFW data reveals that Lake Cushman was stocked with 23,896 cutthroat trout in 2005 a d 205,800 Kokanee (landlocked sockeye salmon) in 2004. A WDFW biologist rep rted that other species that inhabit the lake include rainbow trout(Oncorhynchus mykiss and non-native largemouth bass (Micropterus salmoides). Additionally, Tacoma Power is presently workinE in association with the Skokomish Tribe and the WDFW to reestablish migrating sal nonid runs in the North fork of the Skokomish River. The North Fork Skokomish Powe house and Fish Facility has recently been completed.This facility collects adult fish at the b se of Cushman Dam No. 2 and transports them to the top of the dam for sorting. also provides sorting facilities for juvenile fish and transports them to the base of th darn for release into the river. The fry will be released in Lake Cushman, and smolts wi be collected and released into the lower North Fork Skokomish River. Returning adult sockeye will eventually be collected at the base of Cushman Dam No. 2. Two new hat heries are also under construction, one on the Hood Canal at Potlatch for sockeye,the of ier on Lake Kokanee for Chinook, coho, and steelhead. Hatchery construction is pla ned to be complete in 2015 (Tacoma Public Utilities 2015). 4.1 ESA Listed Species BULL TROUT Bull trout are members of the char subgroup of t e salmon family and are native to the Pacific Northwest and western Canada. Water tei riperature above 15 degrees Celsius is believed to limit bull trout distribution, as eggs ai d juveniles require extremely cold water for survival. Bull trout are also vulnerable o degraded stream habitat,poor water quality, dams and other stream blocking structur s, and predation by non-native fish. Critical habitat includes Lake Cushman and the i pper North Fork of the Skokomish River(70 FR 56304). Critical Habitat in the forry er includes spawning and rearing Denis Biological Evaluation 12 habitat,while the latter provides rearing, foraging#' and migration habitat, so it is expected that bull trout may be found in the action area of the proposed project site. MARBLED MURRELET A small, diving seabird in the family Alcidae,the rnarbled murrelet forages for small fish and invertebrates almost exclusively in nearshore arine waters,while nesting inland in old-growth or mature conifer forests. Threats incl de loss of habitat,predation, gill-net fishing operations, oil spills,marine pollution, an disease. The USFWS assembled a team of scientists in October 2011 to investigate c iuses for the continued decline in murrelet populations. The outcome of these discu sions listed many factors, chiefly loss of potential nesting habitat as the main reason for indrance of population recovery goals (WDFW 2012). Potential nest trees are coniferous trees within 55 i (88.5 km) of marine waters that support at least one 4-inch(10.2-cm) diameter pl form located at least 33 feet(10 meters)above the ground,with horizontal and ve ical cover(USFWS 2012). If a tree or forested area does not support these habitat featu s, it is "extremely unlikely"to support a murrelet nest(USFWS 2012).Nest success is i uenced by forest structure,the spatial mix of habitat and non-habitat,human disturbanc ,prey availability, and marine foraging conditions. Human disturbance can lead to highei predation levels by Steller's and gray jays, crows,ravens, and other species that seek hi man-related foods and refuse at high- use recreational areas (Peery et al. 2004, Marzluf and Neatherlin 2006). Critical habitat for the marbled murrelet,which v as designated in May of 1996 and revised in October of 2011, is located within the roposed project's action area to the northwest of the project site;therefore, it must be assumed that marbled murrelets may be found nesting in the action area. State Route 119 s located between the project site, Lake Cushman, and the marbled murrelets critical habi at, so it is expected that any marbled murrelets nesting in the action area,will do so on the far side (north side) of the highway. Additionally,the proposed project will not result n the loss of any trees or other vegetation, and water quality at the site will be nimally impacted. NORTHERN SPOTTED OWL The Northern Spotted Owl is one of the largest o is in North America, and the average adult female is approximately 18 inches tall with a 48-inch wingspan.Northern spotted owls are strictly nocturnal, and require old-gro forests with multi-layered canopies of trees, including large trees with broken tops, deft rmed limbs, and large holes and cavities to nest in. The Northern spotted owl is very terri rial and intolerant of habitat disturbance, and a pair requires a large amount o forest for hunting and nesting. Habitat loss has occurred as a result of forest conversion timber harvest, fire, windthrow, insect outbreak and disease (WDFW 2012). Denis Biological Evaluation 13 The USFWS designated revised critical habitat fo the northern spotted owl under the Endangered Species Act. In total, approximately 577,969 acres (ac) (3,876,064 hectares (ha)) in 11 units and 60 subunits in California, Or gon, and Washington fall within the boundaries of the 2 critical habitat designations. T ie action area includes designated critical habitat for the Northern spotted owl; how er, due to the close proximity of human habitation, it is unlikely that any Northern potted owls may be found in the action area. Additionally,the proposed project will not result in the loss of any trees or shrubs. STREAKED HORNED LARK Horned larks are birds that utilize wide open spac s with no trees and few or no shrubs. The streaked horned lark nests on the ground in s rsely vegetated sites dominated by grasses and shrubs. Historically this type of habit was found in prairies in western Oregon and Washington, in dune habitats along t coast of Washington, on the sandy beaches and spits along the Columbia and Willa tte Rivers, and in grasslands, estuaries, and sandy beaches in British Columbia(WDFW 0 12). Today the streaked horned lark nests in a broad range of habitats, including nativ prairies, coastal dunes, fallow and active agricultural fields, wetland mudflats, spars y-vegetated edges of grass fields, recently planted Christmas tree farms with extens a bare ground, moderately-to heavily- grazed pastures, gravel roads or gravel shoulders f lightly-traveled roads, airports, and dredge deposition sites in the lower Columbia RiN er(WDFW 2012). It is expected that the action area contains unsuita le habitat for the streaked horned lark. YELLOW-BILLED CUCKOO The yellow-billed cuckoo (Coccyzus americanus) is a neotropical migrant bird that winters in South America and breeds in western 1, orth America. The yellow-billed cuckoo is insectivorous and lives in riparian wooc lands (USFWS 2014). Reports of individual cuckoos have been very rare in recent ecades,with only three known reports since 2000,these being near Lind(Adams Co.) in 2001, near Eureka(Walla Walla Co.) in June 2007, and from Little Pend Oreille Nation il Wildlife Refuge (Stevens Co.) in June 2012. Habitat loss and pesticide use are thou ht to be two of the main causes for the precipitous decline of western yellow-billed cucki ios.Agriculture, grazing, reservoir construction, flood control, urbanization, and othc r factors across the West have caused the large-scale loss and degradation of lowland ril,arian forest, which is the cuckoo's primary habitat. It is expected that the action area contains unsuitable habitat for the yellow-billed cuckoo. Denis Biological Evaluation 14 i ! CHINOOK SALMON Chinook salmon in Lake Cushman are a land-loc ed population that originated from anadromous fish, although loss of genetic variati n makes it difficult to determine whether they are descended from historical Hoo Canal populations or introduced hatchery fish (NOAA 2006). Lake Cushman Chi ook are genetically different, smaller in size (and presumably less fecund)than their ana omous counterparts(Myers et al. 1998). On Jan. 12, 2009,Tacoma Power,the Skoko ish Tribal Nation and state and federal agencies signed a settlement agreement that resol ed a$5.8 billion damages claim and long-standing disputes over the terms of a long-t license for Cushman Hydroelectric Project. Tacoma Power has proposed to introduc sockeye and spring Chinook and enhance the existing winter steelhead and coho p pulations in the North Fork in cooperation with the WDFW and the Skokomish Tribe (Tacoma Public Utilities 2014). In addition,Tacoma Power will annually release up to 100,000 rainbow trout for sport harvest(TPU 2014). Lake Cushman has been designated Critical habi t, and the site provides rearing, foraging,and migration habitat, so it is expected that adult and/or juvenile Chinook salmon may be found in the action area. 5.0 Environmental Baseline Conditions 5.1 Action Area The environmental baseline represents the existii ig set of conditions,to which the effects of the proposed action are then added. The environmental baseline is defined as "the past and present impacts of all Federal, state, and pri ate actions and other human activities in the action area,the anticipated impacts of all pr osed Federal projects in the action area that have already undergone formal or informal ction 7 consultation, and the impact of state or private actions which are contemporane s with the consultation process" (50 CFR 402.02). The proposed project site is in WT JA 16 on Lake Cushman in Mason County. The majority of the fresh and marine w erbodies in WRIA 16 suffer from water quality issues; however, Lake Cushman is not li ted on the state's 2012 Water Quality 303(d) list of impaired waterbodies for any parai neters. Two waterbodies in the Skokomish watershed,the South Fork of the Sk komish River and Lebar Creek are listed for the parameter of temperature (high). The proposed project site is located in a rural ne hborhood on a lot with approximately 66' of frontage on Lake Cushman, in an area cl sified as an Urban Residential shoreline environment by the Shoreline Master Program o F Mason County.Neighboring parcels support single-family residences(or recreational cabins),bulkheads,piers, and floats. Forested land in the vicinity of Lake Cushman h is been logged heavily. Erosion impacts from surface flows have been particularly damal ing in the logged areas above the lake's west shore. Denis Biological Evaluation 15 Before the completion of two dams in 1926 and 1030, Lake Cushman was a natural oligotrophic lake with a mean depth of 200 feet. ow Lake Cushman is 4,010-acre water body in the Olympic National Forest, having beer altered in size to accommodate the hydroelectric dams. Because of the dams,water 1 els in Lake Cushman can fluctuate up to 21 meters(69 feet), with peak levels occurring uring summer and minimum levels during winter. The magnitude of these fluctuation results in periodic inundation of 12 hectares (30 acres) of land surrounding the inlet to the reservoir,resulting in high water temperatures in the shallow waters of the inlet dui ing the summer months (Brenkman 1998). Currently,the reservoir inundates 17.2 kil meters (10.7 miles)of river, including areas of the original Lake Cushman (Brenkman 1 98). 5.2 Proposed Project Area A field investigation was conducted on the aftern on of November 24th of 2015, during which the project area was surveyed visually on ot. The elevation of the lake's water level was approx. 726 feet,which is approx. 12 fc A lower than the current ordinary high water mark of 738 feet. The site supports a single-family residence locate approximately 10 feet vertically and 40 feet horizontally from the shoreline of Lake Ci shman. The lot is moderate to heavily vegetated with native plants and supports approx. fifteen to twenty medium to medium- large conifers. The shoreline is accessed by walki ig past the residence and through the yard. The lake's beach is accessed via the failing oncrete boat ramp. The slope of the beach is moderate in the vicinity Df the bulkhead, and the substrate consists primarily of sand, gravel, clay, and Cobb . There is riprap and smaller basalt rock scattered over the beach along the east side c f the boat ramp. The shoreline of Lake Cushman at the site is exposed to significant fetc . Wave action has exposed the rock and concrete bulkhead's concrete footing,which app rs to have been constructed rather unsubstantially without forms or subgrade place nt. The existing float ramp is slippery and spans the area between the bulkhead and the oat. The float rests on a failing concrete pad. One-man(approx.)angular rock a concrete debris appears to have been placed in front of the float pad and tucked beneat the bulkhead's failing toe in order to alleviate erosion. The beach was littered with dead fir needles.No sh, invertebrates, or macroalgae were observed. Denis Biological Evaluation 16 i i 6.0 Effects of the Action 6.1 Direct Effects Direct effects to the shoreline include: 1) Loss of enthic lakebed habitat from the repair of the existing bulkhead and the two float position ng pilings. 2) Creation of shade from the replacement ramp and float. 3)No contaminat cm to Lake Cushman from the leaching of wood preservatives.4) The prevention of Styro oam®pollution. 5) The alteration of shoreline drift by the boat ramp. 1)As per the engineered design by P.E. Alan Tah (Attachments 2-7),the existing, approx. 66' concrete and rock bulkhead will be p ially removed and have the entire length of its failing face and footing reinforced wi h new concrete. The footprint of the repaired bulkhead's face and footing will be locat4 d approx.two feet landward of the existing bulkhead's toe,while the new footing wil be approx. one-foot landward but subgrade, along approx. 49' of the bulkhead's we ern extent. At the eastern extent,the proposed repair of approx. 17' of existing bulkhe d will be located approx. two feet waterward of the existing bulkhead's face. The fo tprint of the entire replacement footing will be installed subgrade,to a depth of three feet where the footprint of the existing, poorly constructed footing was never installed. T new footing and face repair will occupy approx. 132 sf of benthic lakebed habitat. y moving approx. 49' of the bulkhead landward and 17' waterward, a total of 64 sf of la ebed habitat will be restored. By also removing the concrete boat ramp and the existing oat's concrete landing pad, approx. 784 sf and 10 sf of lakebed habitat,respectively, ill be restored for a total restoration of 858 square feet. Each float positioning post(with a concrete base) will'occupy approx. four sf, so the two posts will occupy eight square feet. However,the area of the posts (approx. 0.45 sf for each post,totaling 0.90 sf)will constitute the onl3 lost surface area, as the concrete bases for each piling will be covered by the lake's (bolt m) substrate. The shoreline access stairs will be constructed in the footprint of the bc at ramp, landward of the proposed bulkhead's toe. In addition, concrete debris that i scattered over the upper beach, occupying benthic habitat,will be removed from he site. Due to the seasonal fluctuations of the lake's wat r level, it is probable that benthic species do not thrive in the nearshore areas of the lake that lack permanent water.No l empirical evidence was found to document if bot terrestrial and aquatic species utilize the upper shoreline habitat, or if it has been too al ered to support normal concentrations of either species. 2)Another direct effect is the creation of shade f m the replacement ramp and float. The overwater structures at the site produce a reducti in light to the underlying aquatic environment by creating a light/dark boundary th t may give piscivorous species an advantage over their prey. The use of over-water tructures in western Washington waters by bass, a common,non-native predator of juven e salmonids,has been documented by several authors. Largemouth bass in Lake Washi on prefer areas of heavy log and Denis Biological Evaluation 17 brush cover over other habitat types; however,the r are commonly found under docks in early spring and are thought to be present until lati summer(Stein 1970). Substrate type typically determines the acceptability of an area f r bass spawning, but adjacent cover and structural complexity are also necessary for pi Aection while the fish are concentrated in shallow water(Stein 1970; Cooper and Crowd 1979; Helfman 1981b; Pflug and Pauley 1984). The substrate type in the vicinity o he bulkhead and landing is gravel, cobble, and rock. Largemouth bass prefer modera to dense vegetation and silt or sand substrate, and nests are constructed at depths fro 0.6 to 1.5 meters, in vegetated areas with soft sediment or gravel substrate on moderat to steep slopes (Pflug 1981). The project site possesses unsuitable habitat for bass, it is doubtful that the proposed float repair will increase the concentration of bass at th site or the occurrence of juvenile salmonid predation by bass. The project site supp rts no existing macrophyte vegetation and has no potential to support macrophyte veget ion, due to the lake's (anthropogenic) seasonal water fluctuations. In addition, White(1 75)determined that phytoplankton primary production is not significantly reduced b narrow residential piers, due to the presence of more optimal light conditions than fbi nd in surface waters,where light intensities are higher than those in which algae th ve. Data suggests that other fish species, including sa monids, are also attracted to the shade produced by over-water structures, so it is possibl that adult salmonids could prey on juveniles at the site. However, researchers have ir licated that structural complexity can moderate predator-prey interactions by providing nore refuges for prey species as well as reducing the foraging efficiency of the predator(( 'ooper and Crowder 1979). This moderation may apply to naturally occurring stru ural habitat complexity, as well as habitat complexity due to the presence of docks, I iers, boathouses and associated pilings (WDFW,WDOE, WSDOT 2001). Shade can also affect migrating salmonids. It is At known whether over-water structures disrupt the migration of salmonids in lakes.Numt rous studies suggest that docks,piers, and floats attract fish,and that the attraction of fis i is linked to shade produced by the object not tactile stimulus. While the effects of sh ide on migrating juvenile salmonids in lakes is unknown, it is also unclear in marine wat rs, and there is no empirical evidence of mortality. The significance of predation to mig ating populations has never been empirically assessed (Simenstad et al. 1999).No :tudies have examined mortality due to predation much less that mortality is attributable I D overwater structures (Nightingale & Simenstad 2001). As previously noted,the proposed project will re It in a negligible reduction of overwater structure coverage at the site from 244 o 240 square feet. However,the existing float and the shoreline beneath it lack w er for approx. six to seven months each year. In conclusion, shade created by the propose project is expected to have discountable and insignificant direct effects on E A listed salmonids that may be in the action area. 3) The leaching of wood preservatives is a Comm n contaminant-related issue with the construction of shoreline SFR appurtenances. As reviously note,no pressure treated Denis Biological Evaluation 18 lumber will be used in this project. Sustainably h rvested Alaska yellow cedar,which is insect and decay resistant, will be utilized for pos rs,joists, decking, and trim. 4) The proposed replacement of the float's expos d Styrofoam®float material with polyethylene encapsulated Styrofoam®floats is petted to prevent the structure from becoming an eventual source of pollution to Lakc Cushman. Expanded polystyrene foam (EPS), commonly known by the trade name of as Styrofoamg is pervasive in the marine environment(CWAC 2008). Polystyrene is made from petroleum and is not biodegradable. Polystyrene is a principle compor rnt of urban litter and marine debris, and it is detrimental to wildlife that ingests it(H vard University 2008). Polystyrene is lightweight and floats. It eventually breaks down into smaller and smaller pieces that fish and other wildlife mistake for food and consume The lifetime of plastics in the marine environment is unknown. Some researchers feel at the composition of conventional petroleum-based plastics as durable polymers m ns they will degrade to increasingly smaller sizes but never disappear(CWAC 2008). In conclusion,the replacement of the existing unencapsulated float material with encapsulated floats is expected to have a benefic'il impact. 5) The existing and replacement boat ramp is a g oin that has the potential to alter shoreline drift patterns at the site. On a natural la e, movement of woody debris and sediments would likely be important habitat proc sses; however, Lake Cushman, which is not a natural lake, lacks water along a signific t portion of its shorelines for approx. six to seven months each year. Additionally,the ke's shoreline is predominantly steep and cobbled as fine sediments are carried to deep r waters by wave action. While large woody debris is removed from Lake Cushman b Tacoma Power, small woody debris is such a prominent feature on the lake's shorelines that it is doubtful a boat ramp impedes its movement.Also, natural lakes in the area hav large conifers along their shorelines that sometimes fall perpendicularly into the wate creating natural`groins. Temporary Direct Effects Temporary direct effects caused by the proposed roject include: 1) Turbidity and sedimentation in Lake Cushman. 2)Noise. 3) ater pollution from incidental release of fuel, oil, or other contaminants. 1) Disturbed substrate from the installation o the replacement footing and steps may result in increased turbidity and sediment tion. As previously discussed,BMPs will be strictly adhered to during constru ion in order to maintain the present water quality of Lake Cushman and prey t runoff and pollution. In addition,the proposed project will take place when the water level in the lake is much lower than the OHWM (738'), so it is probable hat rainfall will slowly disperse any disturbed substrate before it comes into d rect contact with the lake's waters. Therefore, it is expected that turbidity and sedimentation will be minimal. Denis Biological Evaluation 19 2) The main source of construction noise will e from the jackhammering of the concrete and rock bulkhead and the concr(te boat ramp.Noise will be intermittent and is expected to be a maximum of 79 df A at 50 feet. 3)Potential water pollution from accidental r ease of fuel, oil, or other contaminants is another possible temporary direct effect As previously discussed, Spill Prevention Control measures and BMPs s all be implemented during the proposed project. 6.2 Primary Constituent Elements PRIMARY CONSTITUENT ELEMENTS In order to properly analyze the effects on design ted critical habitat, a logical framework must be utilized. In determining what areas are cr tical habitat, agency regulations require the NMFS to focus on the principal biological or hysical constituent elements that are essential to the conservation of the species. The r gulations identify Primary Constituent elements (PCEs) as including, but not limited to: roost sites, nesting grounds, spawning sites, feeding sites, seasonal wetland or dryland, N ater quality or quantity, host species or plant pollinator, geological formation,vegetation ype,tide, and specific soil types (69 FR 71888)."In 2003 NMFS biologists developed list of PCEs specific to salmon, based on a decision matrix(NMFS, 1996)that describe general parameters and characteristics of most of the essential features under considerat n when critical habitat is designated. There are six specific types of sites essential to s port one or more life stages of an ESU (sites for spawning, rearing, migration, and forag g). Each site names physical or biological features (PCEs)essential to the conse ation of salmonids. In 2010, USFWS biologists developed a list of PCEs specific to bu trout, based on a decision matrix (NMFS, 1996)that describes general parameters nd characteristics of most of the essential features under consideration when critic 1 habitat is designated. Lakes and reservoirs figure prominently in meeting the life- ycle requirements of adfluvial bull trout. Lake Cushman is designated critical habita for the bull trout and the Chinook salmon;therefore,the direct effects on the design ited critical habitat of bull trout and Chinook salmon have been analyzed using the ap ropriate PCEs for the nearshore lacustrine environment. BULL TROUT PCEs: Water temperatures that support bull trout use. ull trout have been documented in streams with temperatures from 32 to 72 degree F but are found more frequently in temperatures ranging from 36 to 59 degrees F-- he project will have no direct effect on water temperatures that support bull trout use. Denis Biological Evaluation 20 Migratory corridors with minimal physical, biol ical, or water quality impediments between spawning, rearing, overwintering, andj raging habitats, including intermittent or seasonal barriers induced by hig water temperatures or low flows— the project will have a beneficial direct effect on r iigratory corridors that support bull trout use as approx. 858 sf of benthic lakebed hab tat is restored. Passage will not be altered during construction as no construction wil occur unless the waters of Lake Cushman are low. An abundant food base including terrestrial orgi nisms of riparian origin, and aquatic macroinvertebrates—the project is expected to h e a minimal direct effect on an abundant food base for bull trout. Construction wIll take place when the lake's waters are lowered and approx. 49' of the repaired bulkhead will move landward, returning approx. 64 sf to benthic shoreline habitat. Permanent water of sufficient quantity and qual ty such that normal reproduction, growth, and survival are not inhibited--the proje t is expected to have a minimal direct effect on water quality. Project construction is un kely to cause temporary turbidity or sedimentation as work will occur when the lake's waters have been lowered. BMPs are expected to prevent or moderate potential water p llution during construction.No pressure treated lumber will be used, and un-enca sulated Styrofoam®float material that is apotential source of water pollution will be rep aced with encapsulated floats. CHINOOK SALMON PCEs: Unobstructed passage—the project will have a b neficial direct effect on migratory corridors that support Chinook use as approx. 858 sf of benthic lakebed habitat is restored. Passage will not be altered during constr iction as no construction will occur unless the waters of Lake Cushman are low. Water Quality—project construction is unlikely t cause temporary turbidity or sedimentation. BMPs are expected to prevent or oderate potential water pollution during construction.No pressure treated lumber v ill be used, and un-encapsulated Styrofoam®float material that is a potential sour of water pollution will be replaced with encapsulated floats. Water Quantity—the project will have no effect water quantity. Forage—approx. 49' of the repaired bulkhead w 11 move landward, returning approx. 64 sf to benthic shoreline habitat. Natural Cover—the project will have no direct effect on natural cover. Denis Biological Evaluation 21 6.3 Direct Effects to ESA Listed Spi cies The direct effect from the proposed project to othc r ESA listed species that are likely to be found in the action area have been analyzed as ollows: NORTHERN SPOTTED OWL Due to the close proximity of human habitation an the small size of the action area, it is unlikely that any Northern spotted owls may be fo ind in the action area of the proposed project site. However, the absence of spotted owls in the action area is not a certainty. While proposed project construction may occur be ween March lst and September 30th, which is the nesting season of Northern spotted owls,the following noise threshold guidelines will be followed to ensure minimal dist irbance during project construction: •The proposed project will not remove disper il habitat and will be at least 0.25 mi. (for noise-generating activities besides bla ing) from northern spotted owl suitable habitat(nesting, roosting, foraging:NRF). Note: The rural neighborhood where the site is to ited extends approx. 1.5 mi. south of the proposed project site, 0.10 mi. north to State ute 119, and 0.15 mi. northwest. Beyond the northwest boundary of the neighborho d, SR 119 is located less than 0.08 mi. from the shoreline of Lake Cushman for approx. tl ree miles, heading toward the Staircase recreation area. With the extensive acre a of undeveloped forest land nearby, it seems unlikely that Northern spotted owls will nesting, roosting, or foraging in the vicinity of anthropogenic development. MARBLED MURRELET The primary threats to marbled murrelet from anIshman. opogenic activities include loss of nesting habitat, gill-net fishing operations, oil spi , and marine pollution. Previously noted BMPs and Spill Prevention Control Measu will be adhered to during project construction to protect the water quality of Lake Noise impacts to any nesting or foraging murrelets in the action area are expected to be negligible, although construction may occur during the marbled murrel t nesting season between April 1 through September 23rd. To ensure minimal distui bance to any marbled murrelets that may be nesting in the action area,the following n 'se threshold guidelines will be followed during project construction: •Project activities will occur between two hou s after sunrise and two hours before sunset. •Suitable nesting habitat will not be removed. Note: The rural neighborhood where the site is to ted extends approx. 1.5 mi. south of the proposed project site, 0.10 mi. north to State ute 119, and 0.15 mi. northwest. Denis Biological Evaluation 22 Beyond the northwest boundary of the neighbor h od, SR 119 is located less than 0.08 mi. from the shoreline of Lake Cushman for approx. hree miles, heading toward the Staircase recreation area. With the extensive acre tge of undeveloped forest land nearby, it seems unlikely that marbled murrelet will be nt sting,roosting, or foraging in the vicinity of anthropogenic development. 6.4 Indirect Effects Indirect effects are those effects that are caused b or will result from the proposed action and are later in time, but are still reasonably certa n to occur(50 CFR 402.02). Possible indirect effects from the proposed project include 1)The loss of shoreline aquatic vegetation. 2)The repaired bulkhead exacerbates passive erosion to the shoreline. 3) The repaired bulkhead causes a reduction in the accu ulation of large drift logs on the beach. 4)The replacement float results in an increased rr otorized boat presence at the site. 1) The replacement ramp and float will cause a rc luction in light to the underlying aquatic environment,which can have significant pacts on the health and productivity of both native and non-native macrophytes and al ae. Macrophytes and algae are the foundation for most freshwater food webs and th r presence or absence affects many higher trophic levels (NMFS 2004). It is expecte that the impact of the lake's fluctuating water level on littoral productivity will overshad the impacts of shading from the pier and float at the site. The reduction in overwater coverage at the site of approx. four sf is expected to be insignificant. 2) When waves reflect off shoreline armoring st tures,particularly concrete or other types of flat-faced bulkheads,they can cause sco ing and hardening of the substrate and steepening of the beach. The sediment in front of bulkhead will gradually become coarser as wave action and littoral drift removes t e finer sediment and there is no sediment available for replenishment because it i impounded behind the bulkhead (Macdonald et al. 1994). Hard-armored bulkhead cut off sediment that was once available to feed the beach,thus adversely affectii g natural beach-forming processes. The shoreline at the site is already unnaturally step due to the lake's manmade origin. Accordingly, the steepness has caused significant couring and erosion, as there is no shallow foreshore to diminish the energy from in ming wind waves. Any beach feeding sediments are carried away to deeper water. The r roposed repaired/replacement structures are not expected to minimize scouring d steepening of the beach.A small amount of excavated sediments will be utilized in he project to fill in holes or depressions after the bulkhead footing forms are r moved, but the majority (of excavated sediments)will be removed from the shoreline fo owing the project's completion, as Tacoma Power does not allow excavated sedimen s to be spread over the shoreline at Lake Cushman. Denis Biological Evaluation 23 Referenced materials for this report primarily ass s bulkhead impacts to marine shorelines and, in particular, Puget Sound. While ome impacts are applicable to lake shorelines, beach feeding/forming processes appear to differ significantly and be site specific. On Lake Cushman, a lake whose shorelii es lack water for roughly six months each year, it seems counterproductive to consider each feeding a positive habitat process as the lake was significantly enlarged to accomm( date two hydroelectric dams (that produce environmentally friendly electric power I -ee of carbon emissions). Additionally, the existing boat ramp,which also functions as a ulkhead and therefore has the potential to produce detrimental effects of both a bulkhead nd a groin,will be removed. 3) Shoreline armoring can also limit the accumulation of large drift logs on the beach, as large woody debris is less likely to accumulate on beaches that have steepened due to the presence of a bulkhead(Macdonald et al. 1994). Harge woody debris (LWD) provides detrital input, food sources, and potential refuge r migrating juvenile salmon. Due to the moderate number of power boats that utilize t e lake in the vicinity of the proposed project site, it is not safe to recommend anchorin LWD to the beach.Nor is it allowed by Tacoma Power. In addition,there are numero existing stumps along the shoreline throughout the lake. 4)The replacement float may result in an increas motorized boat presence in the area. Fuel spills from powerboats can contaminate wat r quality and potentially affect listed salmonids directly or indirectly through their pre source (NMFS 2005). Powerboats also create amplified wave action that can erode the st oreline, and prop scouring can erode benthic habitat, although benthic habitat in the li ral zone is already significantly marginalized by the lake's fluctuating water level . Powerboats also provide some oxygenation of surface waters, although the exter t is probably negligible at best. Overall, the indirect effects of powerboat usage on Lake C ushman is likely insignificant due to the lake's large size,the small number of boats that cess the remote lake, and the short boating season(primarily May thru September). 6.5 Primary Constituent Elements PRIMARY CONSTITUENT ELEMENTS The indirect effects on the designated critical hab itat of Bull trout and Puget Sound Chinook have been analyzed using the approprial r,PCEs for the nearshore lacustrine environment. BULL TROUT PCEs: Water temperatures that support bull trout use. all trout have been documented in streams with temperatures from 32 to 72 degre F but are found more frequently in Denis Biological Evaluation 24 temperatures ranging from 36 to 59 degrees F--the project will have no indirect effect on water temperatures that support bull trout use. Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows—the project will have no indirect effect on migratory corridors that support bull trout use. An abundant food base including terrestrial organisms of riparian origin, aquatic macroin vertebrates, and forage fish--mitigation plantings may eventually provide leaf matter and insects for aquatic life in Lake Cushman, improving foraging opportunities for bull trout. Permanent water of sufficient quantity and quality such that normal reproduction, growth, and survival are not inhibited—the use of yellow cedar(rather than pressure treated lumber) and encapsulated float material ae expected to improve water quality. CHINOOK SALMON PCEs: Unobstructed passage—the project will not have any indirect effect on unobstructed passage. Water Quality—the project will benefit water quality (see bull trout). Water Quantity—the project will not have any indirect effect on water quantity. Forage—mitigation lantin s ma eventually r vide leaf matter and insects for aquatic plantings y y p b life in Lake Cushman, improving foraging opportunities for Chinook. Natural Cover—the project will not have any in irect effect on natural cover. 6.6 Indirect Effects to ESA Listed Species The indirect effects from the proposed project to other ESA listed species that are likely to be found in the action area have been analyzed as follows: NORTHERN SPOTTED OWL &MARBLED MURRELET While it is highly unlikely that either species would nest in trees that are located in a rural neighborhood, the proposed project may result in increased recreational usage at the site, which could prompt both species to nest elsewhere. Denis Biological Evaluation 25 6.7 Interrelated/Interdependent Effects Interrelated and interdependent effects are described as the effects of the action under consultation analyzed together with the effects of other activities that are interrelated to, or interdependent with,that action. An interrelated activity is an activity that is part of the proposed action and depends on the proposed action for its justification. An interdependent activity is an activity that has no independent utility apart from the action under consultation (FWS &NMFS 1998). The project will have no obvious interrelated or interdependent effects. 6.8 Primary Constituent Elements BULL TROUT PCEs: Water temperatures that support bull trout use. Bull trout have been documented in streams with temperatures from 32 to 72 degrees F but are found more frequently in temperatures ranging from 36 to 59 degrees F--the project will have no interrelated or interdependent effects on water temperatures that support bull trout use. Migratory corridors with minimal physical, biological, or water quality impediments between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows—the project will have no interrelated or interdependent effects on migratory corridors that support bull trout use. An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish--the project will have no interrelated or interdependent effects on the bull trout's food base. Permanent water of sufficient quantity and quality such that normal reproduction, growth, and survival are not inhibited--the project will have no interrelated or interdependent effects on water supply or quality. CHINOOK SALMON PCEs: Unobstructed passage—the project will have no interrelated or interdependent effects on unobstructed passage. Water Quality—the project will have no interrelated or interdependent effects on unobstructed passage. Water Quantity—the project will have no interrelated or interdependent effects on water quantity. Denis Biological Evaluation 26 Forage—the project will have no interrelated or inter lependent effects on water quantity. Natural Cover—the project will have no interrelated or interdependent effects on natural cover. I 6.9 Cumulative Effects Cumulative effects are defined as "those effects f future state or private activities, not involving Federal activities,that are reasonably rtain to occur within the action area of the action subject to consultation" (50 CFR 402. 2). Cumulative impacts are difficult to access. Continued growth and urbanization is lik ly to detrimentally impact fish and wildlife resources. Global warming could raise t e water level of Puget Sound, leaving many waterfront properties underwater. Global varming could also result in warmer water temperatures,to the detriment of species s ch as bull trout. Additionally, over- fishing may deplete stocks of salmon,even as re oration of habitat in the watershed furthers their likelihood of survival. 7.0 Conclusion 7.1 Take Analysis Section 9 of the ESA prohibits take of endanger or threatened species, "take"being defined in Section 3 as to harass,harm,pursue,I unt, shoot,wound,trap, capture, or collect listed species, or attempt to engage in an such conduct. "Harm" is further defined as a significant habitat modification or degradati n that actually kills or injures listed species by"significantly impairing behavioral p tterns such as breeding, spawning, rearing,migrating, feeding, and sheltering" (50 CTR 222.102). "Harass" is further defined as an intentional or negligent act which i reates the likelihood of injury to wildlife by annoying it to such an extent as to significant y disrupt normal behavior patterns which include,but are not limited to,breeding, eding, or sheltering(50 CFR 17.3). In regards to the proposed project and the existing evelopment activities, it is extremely unlikely that any"take"will occur. Previously li 3ted conservation measures will further insure the likelihood that no "take"will occur. i 7.2 Determination of Effect A determination of May affect, not likely to advi rsely affect is the appropriate conclusion when effects on the species or their critical habii at are expected to be beneficial, discountable, or insignificant. After reviewing tl e appropriate data and survey information, I have concluded that the proposed project will have an insignificant impact on the previously discussed Endangered or Thrc itened species if the previously discussed Denis Biological Evaluation 27 conservation measures are implemented. In my m st honest and professional opinion, while the proposed project may impact individual ndangered or Threatened species in the project area, it is not likely to adversely affect r jeopardize the continued existence of those species or their designated Critical Habit . The determination of effect for each of the listed species is: 1. Bull trout and their designated Critical Ha itat May affect, not likely to adversely affect. 2. Chinook salmon--May affect, not likely to idversely affect. 3. Marbled murrelet—May affect, not likely i adversely affect. 4. Northern spotted owl No effect. 5. Streaked horned lark---No effect. 6. Yellow-billed cuckoo No effect.

Background The Magnuson Fishery Conservation and Mana ment Act was signed into law on April 13, 1976. Under provisions of the Act, eight Re ional Fishery Management Councils were established to prepare FMP's in conforma e with national standards published in 50 CFR Part 600.305-340. The Magnuson Act s renamed the Magnuson-Stevens Act in a 1996 appropriations bill. On October 11, 19 6,the Sustainable Fisheries Act,which amended the Magnuson-Stevens Act,was signe into law. Provisions included a mandate that the Councils amend each FMP to include a escription of Essential Fish Habitat, including adverse impacts on EFH and conserva ion measures to protect EFH. Essential Fish Habitat is defined as those waters and subs t ate necessary to fish for spawning, breeding, feeding, or growth to maturity. The Pacific Fisheries Management Council has esignated EFH for federally-managed species on the Pacific West Coast, including 82 pecies of groundfish, 5 coastal pelagic species, and 3 species of salmon. The following ipecies may occur in Lake Cushman during some period of their life history: Chinoot salmon(Oncorhynchus tshawytscha) and Coho salmon (Oncorhynchus kisutch). B. Essential Fish Habitat The designated EFH for Pacific salmon species I s identified using U.S. Geological Survey(USGS)hydrologic units as well as habil at association tables and life history descriptions of each life stage (PFMC 1999). T EFH for the Pacific coast salmon fishery is defined as those waters and substrate r ecessary for salmon production needed to support a long-term sustainable salmon fishe and salmon contributions to a healthy ecosystem (WSDOT 2014). To achieve that levc I of production, EFH must include all those streams, lakes,ponds, wetlands, and other urrently viable water bodies and most of the habitat historically accessible to salmon it Washington, Oregon, Idaho, and California(WSDOT 2014). This does not incluc r, habitats above the impassible barriers identified by the Pacific Fishery Management C uncil Fishery Management Plan(PFMC 1999). Denis Biological Evaluation 45 i i C. Proposed Action The proposed project is the footing repair(using oured concrete)of an existing failing rock and mortor bulkhead,the repair/reconfigura on of an existing pier and float, and the removal of an existing concrete boat ramp on La Cushman. The action will result in a reduction of overwater coverage at the site of ap ox. 4 square feet and the restoration of approx. 858 sf of benthic lakebed habitat. D. Effects of the Proposed Action The effects of the proposed project on designate EFH are expected to be comparable to the effects described in the attached BE. E. Conservation Measures The conservation measures and BMPs discussed n the attached BE will be implemented to minimize any adverse effects to Essential Fish Habitat. F. Conclusion The proposed project is likely to have no signifi nt impact on designated EFH for Pacific salmon. G. References NOAA, 2006.

All structures are treated as new (no previous permitting for the structures). Replace dock (similar footprint and size), remove boat ramp, repair bulkhead and add inset stairs (not protruding waterward of bulkhead). Replacement of Ramp and Float: Wood components of the existing float will be disassembled using a circular saw and various hand tools. The two, concrete float positioning pilings will be sawed off at beach grade, then sawed or broken into several pieces. Following demolition, all debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to removal from the site. The concrete footings of the float positioning pilings will be excavated to the necessary depth, using manual labor and hand tools or a small tractor, and removed completely. The float landing pad will also be broken up and removed. The proposed dock will project waterward 30' from the bulkhead. The float (12' by 20') and ramp (3' by 14') will be constructed on site and will utilize galvanized steel or aluminum hardware and yellow cedar joists, decking, trim, and posts (4). In addition, the float will be fitted with polyethylene encapsulated Styrofoam® floats. A float landing constructed of yellow cedar lumber will be affixed between the float pilings. Repair the Bulkhead and Add Steps: The bulkhead's (66' long and 6' feet tall from top of bulkhead to top of footing) existing concrete footing along the western extent will be removed, as necessary, using a jack hammer, to provide clearance for the new face and footing. Following demolition, all concrete debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to removal from the site. Excavation of substrate for the bulkhead and shoreline access stairs will be done manually or using a small tractor. The footings will be approx. four feet in depth and three feet in width (4'x 3'). Concrete for the bulkhead and stairs (6.5' wide) will be poured at the same time. Demolition of the Bulkhead Footing Boat Ramp: The concrete boat ramp will be broken up and removed and returned to a natural condition. Mitigation Planting: (no change) Native vegetation will be planted in a ten by twenty-foot (10' x 20') area landward of the bulkhead where vegetation is currently lacking. The author of the BE has recommended that any trees or large shrubs be installed at least ten feet (10') landward of the bulkhead, due to the potential for the roots of trees and large shrubs to damage the bulkhead, especially during summer drought conditions. At least 20 plants and five different species will be installed. Planting will occur in the fall (after the cessation of drought conditions) or in the early spring. Vegetation will be in one or two gallon pots, bare root, or harvested from the site.

It is a requirement of residential and recreational dock, pier, ramp,floats that there be grading in the overwater structures as per WAC 220-660-140. We noticed that in the provided DNS that there is no mention proposed grating for the new structure. The WDFW would like to emphasize that within the WAC 220-660-140(3)(c)(iv)(B) it states the following: "Northeast/southwest, northwest/southeast and east/west oriented piers(23 to 157 degrees,203 to 337 degrees) must have at least fifty percent of the entire deck surface covered in functional grating regardless of width.The grating must be installed parallel to the width of the pier,evenly spaced along the entire length of the pier."The current pier, ramp and float structure is in a northeast/south-west orientation. It is our concern that the shading from the structure will be detrimental to the nearshore habitat within Lake Cushman. Please contact me at(360)602-0364 to discuss any questi ns you might have.

Replacement of Ramp and Float: Wood components of the existing float will be disassembled using a circular saw and various hand tools. The two, concrete float positioning pilings will be sawed off at beach grade, then sawed or broken into several pieces. Following demolition, all debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to removal from the site. The concrete footings of the float positioning pilings will be excavated to the necessary depth, using manual labor and hand tools or a small tractor, and removed completely. The float landing pad will also be broken up and removed. The proposed dock will project waterward 30' from the bulkhead. The float (12' by 20') and ramp (3' by 14')will be constructed on site and will utilize galvanized steel or aluminun i hardware and yellow cedar joists, decking, trim, and posts (4). In addition, the float will be fitted with polyethylene er capsulated Styrofoam®floats. A float landing constructed of yellow cedar lumber will be affixed between the loat pilings. Repair the Bulkhead and Add Steps: The bulkhead's (66' long i ind 6' feet tall from top of bulkhead to top of footing) existing concrete footing along the western extent will be remo ed, as necessary, using a jack hammer, to provide clearance for the new face and footing. Following demolition, a I concrete debris will be gathered from the geo-textile fabric and placed in an appropriate disposal bin prior to remov 11 from the site. Excavation of substrate for the bulkhead and shoreline access stairs will be done manually or using a small tractor. The footings will be approx. four feet in depth and three feet in width (4'x 3'). Concrete for the bulkhead and stairs (6.5' wide)will be poured at the same time. Demolition of the Bulkhead Footing Boat Ramp: The concrete boat ramp will be broken up and removed and returned to a natural state. Mitigation Planting: (no change) Native vegetation will be planted in a ten by twenty-foot(10' x 20') area landward of the bulkhead where vegetation is currently lacking. The author of the BE has recommended that any trees or large shrubs be installed at least ten feet(10') landward of the bulkhead, due to the potential for the roots of trees and large shrubs to damage the bulkhead, especially during summer drought conditions. At least 20 plants and five different species will be installed. Planting will occur in the fall (after the cessation of drought conditions) or in the early spring. Vegetation will be in one or two gallon pots, bare root, or harvested from the site.

Noise: 1) What types of noise exist in t ie area which may affect your project (for example: traffic, equipment, operation, other)? MASON COUNTY ENVIRONMENTAL CHECKLIST The action area for terrestrial noise effects is based upon an ambient sound level of 40 dBA for an area with a population of less than 100 people per mile (WSDOT 2010). In addition, the Olympic National Forest programmatic biological assessment uses an estimated ambient level of 40 dBA for undisturbed forested areas (LISDI 2003). 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. • Noise frequency and levels for the manual demolition of the concrete and rock bulkhead footing, boat ramp, float landing pad and pilings are expected to be short term and moderate, as the contractor will be using a new jackhammer that is much quieter than traditional jackhammers. • In addition, the bulkhead footing and boat ramp concrete is brittle and cracking, so it is expected to break up easily. Nevertheless, the breaking of concrete by jackhammer will produce the proposed project's maximum noise level. • The noise level of the jackhammer that will be used in the proposed project is 105 decibels, whereas the noise level of a traditional jackhammer is approx. 130 decibels. Therefore, the project jackhammer is 21 percent quieter than a traditional jackhammer. To determine the noise level of the jackhammer breaking up concrete at fifty feet, the noise levels of impact equipment were used. Noise levels at 50 feet from impact equipment, including pile drivers, jackhammers, and rock drills can range from 79 to 110 dBA (WSDOT 2014). The noise level at 50 feet from a traditional jackhammer is 89 dBA (WSDOT 2014), so a traditional jackhammer breaking up thin concrete was assigned 100 dBA. 3) Proposed measures to reduce or control noise impacts, if any" The project jackhammer will be 21 percent quieter than a traditional jackhammer breaking concrete, so the project jackhammer breaking concrete will produce a maximum noise level of 79 dBA at fifty feet. 8 LAND AND SHORELINE USE: a.

Noise: 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? MASON COUNTY ENVIRONMENTAL CHECKLIST 8 The action area for terrestrial noise effects is based upon an ambient sound level of 40 dBA for an area with a population of less than 100 people per mile (WSDOT 2010). In addition, the Olympic National Forest programmatic biological assessment uses an estimated ambient level of 40 dBA for undisturbed forested areas (USDI 2003). 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. • Noise frequency and levels for the manual demolition of the concrete and rock bulkhead footing, boat ramp, float landing pad and pilings are expected to be short term and moderate, as the contractor will be using a new jackhammer that is much quieter than traditional jackhammers. • In addition, the bulkhead footing and boat ramp concrete is brittle and cracking, so it is expected to break up easily. Nevertheless, the breaking of concrete by jackhammer will produce the proposed project's maximum noise level. • The noise level of the jackhammer that will be used in the proposed project is 105 decibels, whereas the noise level of a traditional jackhammer is approx. 130 decibels. Therefore, the project jackhammer is 21 percent quieter than a traditional jackhammer. To determine the noise level of the jackhammer breaking up concrete at fifty feet, the noise levels of impact equipment were used. Noise levels at 50 feet from impact equipment, including pile drivers, jackhammers, and rock drills can range from 79 to 110 dBA (WSDOT 2014). The noise level at 50 feet from a traditional jackhammer is 89 dBA (WSDOT 2014), so a traditional jackhammer breaking up thin concrete was assigned 100 dBA. 3) Proposed measures to reduce or control noise impacts, if any" The project jackhammer will be 21 percent quieter than a traditional jackhammer breaking concrete, so the project jackhammer breaking concrete will produce a maximum noise level of 79 dBA at fifty feet. 8 LAND AND SHORELINE USE: a.
