(Lead agencies may modify this form to include additional specific information on project description.) This project proposes to restore a large area of eroded intertidal beach by re-routing and extending two stormwater outfalls from upper intertidal to low intertidal/subtidal elevations. Habitat restoration will include replacing eroded beach sediment with similar material to its original contours and elevations and removing old construction debris from intertidal habitat. Stormwater outfall improvements will include repairing and improving Alderbrook Resort Stormwater Outfalls Repair -2- April 2008 Environmental Checklist y TO BE COMPLETED BY APPLICANT P �// an existing floating dock and replacing part of a collapsed stone wall on adjacent property that was damaged by stormwater discharges. The project site is a commercial resort in operation since 1913 with a floating dock that provides fuel and a sewage pump-out for south Hood Canal visitors and public access to the resort and its facilities. Resort facilities and amenities include a restaurant, saltwater swimming float, swimming pool, kayak rentals, beach combing, and shellfish digging within the resort's Class 2 tidelands with oyster beds certified for harvest and consumption. The total area of project site, within Alderbrook tidelands between mean higher high water(MHHW)and extreme low water(ELW) is 21,700 ft2 (0.5 ac). In 2004, the resort completed a major renovation and expansion, which included a new stormwater collection and treatment system, restoration of a small creek (Alderbrook Creek) for salmon habitat, and extensive landscaping improvements with native plants. The new stormwater treatment system uses bioswales and filters that retain and treat stormwater from all paved areas, including sidewalks, access drives, and parking areas, in addition to small areas of lawn and large areas of native vegetation. The treated stormwater is released via two stormwater outfalls located at mean higher high water on the east and west sides of the resort. This project would restore 0.14 ac/58 cy of eroded upper intertidal beach with native (or matching) fill,remove more than 200 ft2 of debris from intertidal beach, extend two existing stormwater outfalls from approximately MHHW to subtidal elevations(below -3 ft MLLW), modify the existing marine float to eliminate its grounding footprint, replace 21 creosote wood piles with 21 galvanized steel piles, replace 5,234 ft2 of marine float solid decking with grated decking, and replace part of a collapsed stone wall on an adjacent property. The project would result in a net increase of 3,322 ft2 of fine-grained intertidal habitat. The existing standpipe at the eastern outfall will be removed and replaced with a concrete coupling that will allow the outfall extension pipe to drop below grade and run westward, parallel to the bulkhead, turn northward, under the floating dock, before terminating at -3 ft MLLW. Pipe material will consist of 395 ft of 18-in-dia corrugated polyethylene storm sewer pipe (CPSSP) and 195 ft ofl 8-inch high-density polyethylene (HPDE). All pipe laid parallel to the bulkhead will be buried three to six feet below grade. Under the dock, the pipe section nearest the bulkhead will be buried for a distance of 90 ft, 50 ft of pipe will be partially buried, and 190 ft of pipe will be elevated above the seafloor using concrete anchors to allow littoral movement of fish, oyster spat, and beach sediment. The floating dock and perpendicular moorage floats will be removed to accommodate pipeline construction. After the pipeline is installed, all floats will be replaced(within the same footprint)by sections that will use improved flotation, grated decking, and steel piles. Forty-eight(48) 8-in-dia steel piles will be installed to support the bottom of the floating dock a minimum of 12 inches above grade at low tides. Piles will be installed in pairs across the width of the dock from the bulkhead to -4.5 ft MLLW. Each pair will be connected by an 8-ft-long treated wood beam (12- by 12-in cross section)to support the dock at low tides. Wood treatment will be ACZA (ammoniacal copper zinc arsenate). Alderbrook Resort Stormwater Outfalls Repair -3- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT Y Pairs of pile stops will be spaced between 14 and 18 ft apart. New flotation will consist of high-density polyethylene(HDPE)tubs configured to allow fish passage between and under the tubs. Fifty-two percent of existing solid wood decking will be replaced with grated decking. The old dock will be donated to the Skokomish Tribe. The existing western outfall will be extended from the bulkhead for a distance of 330 ft to terminate at-3.5 ft MLLW. The section of pipe nearest the bulkhead will be buried for a distance of 270 ft. The remaining 60 ft will be partially buried up to the outfall. Following pipeline construction, approximately 58 cy of material similar to the existing beach substrate will be salvaged from the site (from the pipeline trench sidecasting) and/or imported to restore the natural beach profile. In addition, over 200 feet of abandoned concrete,metal, and wood stave and plastic pipe will be removed and disposed of in a landfill. Construction equipment will consist of a small, rubber-tracked or similar type of excavator to dig the pipeline trenches during low tides. Pile extraction and installation will be done during high tides by a vibratory pile driver mounted on a barge. Equipment access to the upper beach will be provided by a private drive on the adjacent east property. Other material, including pipe, anchors, replacement float sections, and imported fill, will be brought to the site by barge. Construction(in 2008) is estimated to take 14 days over a period of 3 weeks to take advantage of the tides. The salmon and trout combined allowable in-water work periods are July 15 —February 15. No forage fish spawning areas or herring holding areas are recorded by WDFW at this location. Additional details of the project construction and schedule information were provided in JARPA Attachment A(December 2007). Engineering drawings and design details, revised in April 2008, are provided in JARPA Attachment B (attached). 12. Location of the proposal.

Alderbrook Resort Stormwater Outfalls Repair -4- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT oc l B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site(circle one): Flat, rolling,hilly,steep slopes, mountainous, other. The shoreline adjacent to the project construction area is flat. b. What is the steepest slope on the site (approximate percent slope)? 3- 5 percent c. What general types of soils are found on the site (for example, clay, sand, gravel,peat, muck)? If you know the classification of agricultural soils,specify them and note any prime farmland. Marine sediment is sandy gravel,with a fraction of surficial fines (i.e.,this is a low- energy marine beach between mean higher high water and extreme low water). No construction will occur waterward of MHHW. Upland soils are a mix of native and imported material. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No. e. Describe the purpose, type,and approximate quantities of any filling or grading proposed. Indicate source of fill. Not applicable. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. No upland clearing or construction will occur from this project. Shoreline access is almost entirely on existing paved drives, so erosion is not anticipated. A short distance of grass between a private drive and the upper shoreline(on an adjacent property)will be covered with plywood to prevent vehicle ruts through the property. Any disturbed areas will be immediately restored following construction. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Alderbrook Resort Stormwater Outfalls Repair -S- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT le3c Y No upland areas will receive new impervious surfaces. The total area of new impervious surface in the intertidal would be about 247 ft2, consisting of the 19 concrete anchors that will elevate part of the eastern outfall extension,the pipe sections that transition from buried to exposed(each about 50 ft long), 48 pile stops, and the bulkhead connections between the existing stormwater outfalls and the new pipe extensions. This total area is about one percent of the Alderbrook intertidal property (21,700 ft2). The increase in new impervious surface will be offset by the removal of about 200 ft2 of old pipe and debris and the elimination of 3,072 ft2 of dock flotation that currently rests on the beach substrate at low tides. The project would result in a net increase in fine-grained intertidal substrate of 3,322 ft2. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: A Temporary Erosion Sedimentation Control plan will be fully implemented. Construction techniques will utilize Best Management Practices (BMPs) such as those described in the Stormwater Management Manual for Western Washington (2004). Silt fences,plywood sheets, or other appropriate erosion control measures will be erected at appropriate locations. To reduce or control erosion in the intertidal,the construction area will be limited to a 25- ft-wide corridor along the alignment. The allowable outfall construction area will be semi-permanently flagged before construction vehicles begin working below MHHW. Flagging, especially rebar stakes, will be removed after construction has been completed. Excavation and fill within the upper to mid-intertidal zone will occur only during periods of low tide. Trenches will be backfilled within a day of excavation. Float-and-sink pipe installation, dock replacement,and pile extraction/driving will occur only during high tides. Barges and boats will not be allowed to ground during low tides. A Spill Prevention Control and Countermeasure(SPCC)Plan will be prepared and implemented by the contractor. The plan will be site-specific, cover the project scope of work, and include the following elements: • Site- and project-specific information. • Spill prevention, control and containment methods. • Response protocols and reporting procedures for construction-related leaks or spills. • Contingency plan and provisions. • Waste disposal methods and locations. • Proper management of oil, gasoline and solvents used in the operation and maintenance of construction equipment. The SPCC will ensure that equipment will be free of external petroleum-based products prior to entering the work area and during the work, and for making any necessary repairs prior to returning the equipment to operation in the work area. This SPCC will be consistent with requirements of W SDOT 2006 Standard Specifications section 1-07.15(1) and the State of Washington Oil Spill Contingency Plan. No vehicles or equipment will be serviced with oil-based products or refueled within the Alderbrook intertidal property. Alderbrook Resort Stormwater Outfalls Repair -6- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT L-Y 7 Equipment staging and/or materials storage will not be allowed on the beach. Equipment and materials will be delivered as-needed on a daily basis by rubber-tracked vehicle or barge. All unplaced construction materials and debris will be removed from the shoreline on a daily basis prior to leaving the site for the work day. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Construction equipment exhaust will occur during the expected two-three weeks of construction. No emissions will occur from the project after construction is completed. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. None. c. Proposed measures to reduce or control emissions or other impacts to air, if any: None. 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater,lakes,ponds,wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The proposed work will be in Hood Canal (WRIA#14). A nearby stream is Alderbrook Creek, which was reconstructed in 2002 from a narrow drainage channel into a meandering creek with a riffles/pool habitat complex and native riparian vegetation. The mouth of Alderbrook Creek is within the project area, between the marine float and the western outfall. 2) Will the project require any work over,in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes,the entire project will occur within intertidal elevations of marine waters (see JARPA for details and construction drawings). No construction will occur above MHHW. Construction for the eastern outfall extension will occur from an elevation of approximately 9.2 ft MLLW to -3.0 ft MLLW. Construction for the western outfall will Alderbrook Resort Stormwater Outfalls Repair - 7- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT occur from approximately 9.2 ft MLLW to-3.5 ft MLLW. Repair/replacement of the floating dock, including piles,will occur between mean higher high water(about 13.5 ft MLLW) and about-16.5 ft MLLW. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. The purpose of the project is to restore intertidal habitat that has been severely eroded by stormwater discharges in the upper intertidal; therefore,the project will result in a net increase of fill material to restore native grades and fill eroded areas. Any removal of material is either temporary (to lay pipe)or restorative (debris removal). Roughly 45 cy of material will be temporarily removed (sidecast) along the pipeline construction alignments to install the outfall extensions. The total intertidal area that may be disturbed during construction is about 0.53 ac. This area is within a 25-ft-wide swath that extends along the pipeline alignment and is referred to as the allowable construction limit. Imported fill includes the following: small gravel and sand"habitat mix" sized similarly to the site's natural substrate, rock and large gravel that will be added under and around the buried sections of pipe to create a stable foundation, about 3 cy of concrete to build connections between the bulkhead and both proposed pipeline extensions, about 0.25 cy concrete to separate the eastern outfall extension from the sewer pipeline near the bulkhead, 920 ft of 18-in-dia pipe to extend the outfalls, 17 ft 2 of stop piles, and about 22 cy of concrete anchor/supports. Approximately 58 cy will be used to restore the natural surface grade over 0.14 acres of eroded beach. Part of the fill material will be salvaged from native material excavated from the pipeline trenches and the remainder will be imported; grain size will be similar to the native beach material. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. 5) Does the proposal lie within a 100-year floodplain? If so,note location on the site plan. Yes; the entire intertidal area is considered floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. The removal of 19 creosote-treated wood piles may be considered waste removal from surface waters. Alderbrook Resort Stormwater Outfalls Repair -8- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT b. Ground: 1) Will groundwater be withdrawn, or will water be discharged to groundwater? Give general description, purpose,and approximate quantities if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals. . . ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None. c. Water runoff(including stormwater): 1) Describe the source of runoff(including storm water) and method of collection and disposal,if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The project will not change the source of stormwater runoff or method of collection and disposal. Site stormwater will continue to discharge into Hood Canal, but at deeper intertidal elevations, where the new outfalls will be submerged almost all the time. 2) Could waste materials enter ground or surface waters? If so, generally describe. The proposed project will not generate or disturb waste materials. A sewage pump- out station for visiting boats will be temporarily removed during dock replacement. The pump-out station does not store waste, so disconnecting the pump will not result in the release of waste. The removal of 21 creosote-treated wood piles may be considered waste removal from surface waters. The piles will be transported from the site by barge, cut into 4- ft-long pieces, and transferred to an upland disposal facility. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: (Repeated from B.l.h.) A Temporary Erosion Sedimentation Control plan will be fully implemented. Construction techniques will utilize Best Management Practices(BMPs) such as those described in the Stormwater Management Manual for Western Washington (2004). Silt fences,plywood sheets, or other appropriate erosion control measures will be erected at appropriate locations. To reduce or control erosion in the intertidal,the construction area will be limited to a 25-ft-wide corridor along the alignment. The allowable outfall construction area will be semi-permanently flagged before construction vehicles begin working below MHHW. Flagging, especially rebar stakes,will be removed after construction has been completed.

Is the site part of a migration route? If so, explain. Yes,the site is part of a migration route for both juvenile and adult salmon, steelhead, and bull-trout. d. Proposed measures to preserve or enhance wildlife, if any: The project was designed to eliminate beach erosion from two stormwater outfalls, restore the beach to its native grade, and recover oyster beds. To achieve its restoration Alderbrook Resort Stormwater Outfalls Repair -11- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANTG( goal, the two outfalls were designed to be extended to near-subtidal elevations,routed around existing oyster beds, and buried along most of the new alignments. Along the deepest section of the extended eastern outfall, where the pipe emerges from below grade, about 190 ft of pipe will be elevated about four inches off the bottom to allow water and sediment circulation and fish passage. To avoid digging through existing oyster beds, the eastern outfall alignment was routed along the bulkhead and under the existing floating dock. This route will require the floating dock to be replaced with a modified floatation system that will accommodate the pipe. The dock will be replaced within the same location and footprint. Dock components will be assembled in sections off site and floated into place above the pipeline alignment during high tide. The replacement dock will be constructed from a recycled wood-composite material (e.g., Trex®). Replacement details are shown in the April 2008 JARPA Attachment B, Figures 21-23. About 52 percent of the decking will consist of expanded steel grating to allow greater transmission of light through the dock. The old friable Styrofoam slab flotation will be replaced with small polyethylene tubs configured to fit around the new pipeline. Pile stops will be used to eliminate all dock area that currently grounds on the beach at low tide, recovering about 3,025 ft2 of substrate. Dock modification and debris removal will result in a net increase of 3,322 ft' of fine-grained intertidal habitat. All 21 creosote piles will be removed and replaced in approximately the same locations by steel piles. All piling removal and installation will be completed using vibratory hammers to minimize the noise impacts on wildlife, especially marbled murrelet. Any piles that cannot be removed will be cut off at or below the seafloor level. All creosote piles will be disposed of at a suitable upland disposal facility. All removal and replacement of piles will be conducted by barge at high tide. No pile driving equipment will be allowed to anchor in oyster beds or ground on the beach. The western outfall will be extended from the existing bulkhead approximately 330 ft to an outlet elevation of-3.5 ft MLLW. About 270 ft of pipe will be buried and 60 ft will be exposed. During discussions in the fall of 2007 with Dan Guy (NMFS), this alignment was determined provide the maximum benefits for federally listed threatened and endangered species and critical habitat,while causing only temporary harm (i.e., digging) to the oyster beds. All in-water activities will take place during the WDFW and USACE (combined) in- water work window of July 16 to February 15 for the protection of salmonids. The restoration of the existing eroded channels will include the removal of the abandoned pipes (over 100 ft of wood stave pipe and 100 ft of concrete pipe), concrete and rock debris, and plastic conduit, and the demolition of an existing cantilevered concrete block at the end of the outfall standpipe. The collapsed section of the adjacent property's rock wall will be replaced in-kind. The eroded channel near the existing bulkhead will be filled with native or similar material. Native beach material and/or habitat mix (approximately 35 cy)that matches the existing surface grain size will be used for final backfill and grading east of the floating dock to natural beach grades. Alderbrook Resort Stormwater Outfalls Repair - 12- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT 7 Beach restoration will include the removal of abandoned pipes(over 100 ft of wood stave pipe and 100 ft of concrete pipe), concrete and rock debris,plastic conduit, and the demolition of an existing cantilevered concrete block at the end of the outfall standpipe. About 35 cy of native or similar-sized imported habitat mix will be used to fill eroded channels and return beach near the eastern outfall to native grades. Nineteen creosote piles(about 10-in-dia)will be replaced with equivalent diameter steel piles. Approximately 23 cy of native material and/or habitat mix will be used to re-grade the erosion that has occurred on the beach in the vicinity of the western outfall. A total of approximately 58 cy of fill material will restore about 0.14 ac of intertidal habitat and allow oysters and other shellfish to recolonize the currently impacted beach. 6. Energy and natural resources a. What kinds of energy (electric, natural gas, oil,wood stove, solar)will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. None. Both outfall systems work via gravity. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. No. C. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts,if any: None (no energy will be used). 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste that could occur as a result of this proposal? If so, describe. No. The existing stormwater treatment system will not be affected by this project. The stormwater outfalls will be extended to discharge into near-subtidal waters,to achieve maximum dilution. The resort stormwater is not known to be toxic or hazardous. Most of the stormwater runoff is composed of natural drainage from seeps and runoff from "clean"areas (e.g., landscaped areas, roof drains, sidewalks). Runoff from the parking areas is wither infiltrated or treated before release. Runoff from SR-106 is either infiltrated or treated before release. Alderbrook is located in a rural, remote location that does not have heavy traffic or industrial activity nearby. 1) Describe special emergency services that might be required. Not applicable Alderbrook Resort Stormwater Outfalls Repair -13- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT 2) Proposed measures to reduce or control environmental health hazards,if any: Stormwater from both parking lots are collected and directed into bioswales, infiltration trenches and sand filters per the Washington State Department of Ecology Stormwater Design Manual (2000). b. Noise 1) What types of noise exist in the area which may affect your project(for example: traffic, equipment, operation, other)? None. Existing noise onsite would come from recreational boats, but no boats will have access to the resort during construction because the dock will be temporarily removed. 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. During construction there will be short-term noise from the equipment used, which may include rubber-tracked excavators, light-weight dump trucks, a pneumatic powered jack hammer(for concrete removal), a tug-assisted barge and a vibratory pile driver. No pile proofing is required. Construction will occur during daylight hours. 3) Proposed measures to reduce or control noise impacts, if any: Air compressors for the pneumatic powered jack hammer will be placed away from beach and guests. Land-based construction vehicles will be equipped with mufflers. 8. Land and shoreline use a. What is the current use of the site and adjacent properties? The current use of the site is hotel/resort that has been in existence since 1913. The resort dock is used by the public for access to recreational moorage, fuel, a sewage pump-out station,the resort shoreline and waters,and the resort restaurant. Adjacent properties to the west and east are residential. b. Has the site been used for agriculture? If so, describe. No. The site includes Class 2 tidelands and is currently certified for shellfish harvest. C. Describe any structures on the site. Structures existing on the property consist of the resort hotel complex and spa; an enclosed swimming pool; 21 resort cottages; a concrete bulkhead along the shoreline; a Alderbrook Resort Stormwater Outfalls Repair -14- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT / floating dock with a sewage pump-out station, fuel, and associated office; a kayak rental float and swimming float;paved parking areas; a sewage treatment system; and a stormwater collection and treatment system with two outfalls that are the subject of this application. Details and photos of the structures affected by this proposal are provided in JARPA Attachment A(December 2007) and the latest engineering details are in JARPA Attachment B of April 2008 (attached). d. Will any structures be demolished? If so,what? The existing eastern outfall standpipe and concrete slab will be removed. e. What is the current zoning classification of the site? Rural tourist f. What is the current comprehensive plan designation of the site? Rural g. if applicable, what is the current shoreline master program designation of the site? Urban Commercial h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. The site is a privately owned Class 2 Tideland certified for shellfish harvest. The site has extensive oyster beds. The site is also habitat for federally listed threatened and endangered species of salmonids (i.e., Hood Canal summer chum salmon, Chinook salmon, Puget Sound steelhead, and bull trout). i. Approximately how many people would reside or work in the completed project? None. j. Approximately how many people would the completed project displace? None. k. Proposed measures to avoid or reduce displacement impacts, if and: Not applicable. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The project purpose is to restore and enhance 0.14 ac of intertidal beach habitat and oyster beds. The outfall extensions were designed to eliminate intertidal erosion, prevent future erosion from stormwater discharges by submerging the outfalls, achieve maximum Alderbrook Resort Stormwater Outfalls Repair -1 S- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT stormwater mixing in Hood Canal outside the elevations of critical habitat use by juvenile salmonids,and allow shellfish beds to recover. The outfall extensions were designed to minimize impacts to existing oyster beds and minimize the footprint of pipe resting on the beach. The dock replacement was designed to eliminate the area of dock that currently grounds on the beach, maximize the amount of light penetration through the dock(by using grated decking over 52 percent of the surface) and remove creosote from the marine environment(by using steel piles). The dock will retain its fuel and sewage pump-out services and public access to the shoreline. 9. Housing :1. Approximately how many units would be provided, if any? Indicate whether high, middle, or low-income housing. Not applicable. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle,or low-income housing. Not applicable. C. Proposed measures to reduce or control housing impacts, if any:y: Not applicable. Ill. Aesthetics a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? The outfall extensions will be 18-in-dia black plastic pipes. About 50 ft of the western outfall will be visible at extreme low tides. The eastern outfall will be buried and hidden by the floating dock. At low tides,the replacement dock will project about one foot higher than the existing dock because of the pile stops. The pile stops will be installed under the dock, so no additional piles will be visible. b. What views in the immediate vicinity would be altered or obstructed? No views will be altered by the eastern outfall extension. About 50 ft of the western outfall will be visible at extreme low tides for about an hour during daylight, a few days each year. At low tides,the replacement dock will project about one foot higher than the existing dock because of the pile stops. The pile stops will be installed under the dock, so no additional piles will be visible. C. Proposed measures to reduce or control aesthetic impacts, if any: The eastern outfall alignment was designed to be buried along the bulkhead and hidden under the existing dock for the remainder of the extension. The alignment was chosen to avoid oyster beds and reduce aesthetic impacts for the resort. The western outfall Alderbrook Resort Stormwater Outfalls Repair -16- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT Wf' alignment was designed to move the outlet to the deepest elevation possible, while remaining on resort property and to minimize the length of pipe visible during low tides. About 50 ft of the western outfall will be visible at extreme low tides for about an hour during daylight, a few days each year. The pile stops were designed to support the dock from below so that the 48 additional piles would not affect aesthetics. Removal of old debris, replacement of the damaged rock wall, removal of the stormwater outfalls from the bulkhead to near-subtidal elevations, and restoration of the eroded beach are aesthetic improvements. 1 1. Light and glare a. What type of light or glare will the proposal produce? What time of day would it mainly occur? The proposed project would not alter existing lighting. If construction occurs at night, temporary lighting would be required. b. Could light or glare from the finished project be a safety hazard or interfere with views? If construction is scheduled at night, temporary lighting would be necessary for safety. Construction lighting would temporarily interfere with views, but the interference would be of short duration, at night, during winter low tides, when fewer people use the resort or adjacent summer homes. c. What existing off-site sources of light or glare may affect your proposal? None. d. Proposed measures to reduce or control light and glare impacts, if any: Due to the higher cost of night construction, the project would try to minimize night construction, and consequently, night construction lighting. 12. Recreation a. What designated and informal recreational opportunities are in the immediate vicinity? Swimming, boating, clamming,kayaking,oyster collection, and dining occurs within or adjacent to the project area. The dock provides public access to the shoreline and to the resort restaurant. b. Would the proposed project displace any existing recreational uses? If so, describe. The proposed project would temporarily displace some recreational uses during dock replacement. Alderbrook Resort Stormwater Outfalls Repair - 17- April 2008 Environmental Checklist TO BE COMPLETED BY APPLICANT c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: Because the project site is a resort, the proposed project has been designed to minimize, reduce, and control impacts on recreational opportunities. The extension and burial of stormwater outfalls was designed to eliminate beach erosion and recover shellfish beds for recreational users. The replacement dock will enhance public access between the shoreline,water, and resort. The removal of abandoned pipes and creosote piles will enhance recreational use. The restoration of the beach and tidelands will provide enhanced recreational opportunities. 13. Historic and cultural preservation a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe. No. b. Generally describe any landmarks or evidence of historic, archaeological,scientific, or cultural importance known to be on or next to the site. There are no known historic landmarks located on or near the site(per Washington Department of Historic Preservation WISAARD online search). c. Proposed measures to reduce or control impacts, if any: If any evidence of historic, archaeological or cultural importance is discovered during construction,the State Historic Preservation Office will be notified immediately and appropriate measures taken. 14. Transportation a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on site plans, if any. The major road in the project vicinity is State Route (SR) 106. Access will be via existing connections b. Is site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? The Alderbrook Inn is currently serviced by public bus, which travels between Belfair and Shelton. It passes the resort twice a day, and stops when requested. c. How man parking spaces would the completed project have? How man would the YP g P P P J Y project eliminate? Not applicable.
