SUMMARY OF PROPOSED ACTION The applicant,the City of Federal Way, is proposing to make habitat improvements and implement sediment control measures on a segment of the West Fork of the Hylebos Creek. The portion of the creek where the work is proposed extends from the southerly end of the West Hylebos Wetlands State Park, south to the point where the creek meets Pacific Highway South. The project consists of a series of engineered logjams and log weirs to stabilize the stream channel and trap channel sediment in place.An abandoned garage type building will be removed and several concrete foundations located on the east side of the creek will be removed. Blackberries and other invasive plant species will be removed and the cleared area revegetated with native riparian vegetation and upland forest species. Within the ravine area, potted conifers will be planted by hand to re-establish a conifer forest along both sides of a section of the creek. There is a two-acre pond adjacent to the creek which discharges to the creek via two small(10"& 12") plastic pipes. These pipes will be removed and a fish ladder constructed to provide fish access to this pond. Refer to the attached Project Features map for locations of the various project elements.

Give brief,complete description of your proposal,including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. The project proposes habitat improvements and sediment control measures for the West Fork of Hylebos Creek. The project area is located in the southern portion of the City of Federal Way (Figure 1). The West Fork of Hylebos Creek has a high sediment load that tends to deposit downstream of Pacific Highway South(Highway 99). This impacts fish habitat and contributes to frequent flooding at an existing bridge at S. 373`d Street. Investigation has identified several sources of sediment in a one-mile stretch of the creek upstream of Pacific Highway South. A large,recent landslide has placed unstable soils in proximity to the stream channel. There is evidence of several additional, older landslides that have contributed sediment to the stream in the past. A series of gravel bars and terraces have formed downstream of these landslides. It is likely that high stream flows readily mobilize these features,moving large amounts of sediment downstream. In addition, there are a number of exposed streambanks which contribute lesser amounts of sediment to the stream. Most of the area along this stretch of the stream lies within a forested ravine. It is not • accessible by road. Therefore, a conventional,large-scale slope stabilization project is not feasible. Instead the strategy behind this project is to stabilize sediment in place and reduce the excessive downstream movement of sediment,to the extent practical, emphasizing the use of bio-engineering measures. The project will consist of a series of engineered log jams and log weirs to stabilize the stream channel and trap channel sediment in place (Figure 2). Three sets of three to five log weirs are proposed in the vicinity of Stations 13+50, 18+00 and 25+00. (The stations refer to feet above the stream crossing(plus 1,000)at Pacific Highway South. For instance, Station 13+50 is located 350 feet upstream of the highway.) There are several sizable drops in the channel grade at the bridge at 3 Station 13+50. The primary purpose of the five log weirs at this location would be to improve fish passage. Twelve engineered log jams are proposed between Stations 20+00 and 41+00. Three log revetments (short logs pinned together)are proposed to protect eroding streambanks: two between Stations 24+00 and 25+00 and one at Station 41+50. An abandoned garage-type building and several concrete foundations located on the east side of the stream near Station 25+50,would be removed. Blackberries and other invasive plant species currently cover approximately 0.6 acres in this area. This area would be cleared and revegetated with native riparian vegetation and upland forest species. In addition, 2.4 acres of riparian area along approximately 800 feet of the east streambank,upstream of South 356th Street,would also be cleared and revegetated with native riparian species. Up to two dozen fabricated"ELWd"logs may be installed in this area by a stream advocacy group: Friends of the Hylebos. Finally,within the ravine area,potted conifers would be planted by hand to re-establish a conifer forest along both sides of the stream,between Stations 28+00 and 40+00. There is road access to the sites proposed for the log weirs and clearing/revegetation,allowing for construction equipment access. The materials for the engineered log jams and one or more of the log revetments would be delivered by helicopter and assembled and placed by hand,avoiding the need to pioneer new roads into the project area. A pond formed by a berm placed across a small ravine exists on the west side of the creek, a short distance upstream of Pacific Highway South,near Station 13+50. The pond covers about 2 acres and discharges to the creek via one 10-inch plastic pipe and one 12-inch plastic pipe. In addition there is a third(10-inch diameter)pipe whose flow is controlled by a gate valve. A fish ladder will be constructed from the pond to the creek. The ladder will consist of a series of low(6-inch) log weirs constructed in a channel approximately 200 feet in length. The ladder will allow fish access to the lake and provide off-channel habitat and refuge which are generally lacking along this stretch of the creek. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address,if any,and section,township, and range,if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description,site plan,vicinity map,and topographic map,if reasonably available. While you should submit any plans required by the agency,you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project area is located in the southern portion of the City of Federal Way. The project proposes habitat improvements and sediment control measures for an approximately one mile-long stretch of the West Fork of Hylebos Creek. The northern boundary of the project area is located approximately 800 feet north of South 356th Street and the southern boundary is where Pacific Highway South(Highway 99)crosses the West Fork of Hylebos Creek(see attached vicinity map). The stretch of the West Fork of Hylebos Creek that will be improved as part of the project lies within the following quarter sections: 4 NW '/4 of Section 29, Township 21 North,`Range 04 East SW '/4 of Section 29,Township 21 North, Range 04 East B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site: Flat, rolling,hilly, steep slopes, mountainous,other. The topography of the project site varies considerably. The north and south portions of the project area are flat to rolling,while the middle section of the project area flows through a steep-sloped ravine. The elevation of the stream at the northern boundary of the project area is approximately 180 feet,while the elevation at the southern end of the project area is 90 feet. b. What is the steepest slope on the site (approximate percent slope)? The steepest slopes along the corridor are approximately 50%. c. What general types of soils are found on the site(for example, clay,sand,gravel,peat, mulch)? If you know the classification of agricultural soils,specify them and note any prime farmland. According to the Soil Survey, King County Area, there are four soil series within the project area: Norma Sandy Loam-These soils are made up of poorly drained soils that formed in alluvium, under sedges, grass, conifers, and hardwoods. A representative profile consists of a surface layer that is black sandy loam about 10 inches thick, and a subsoil that is dark grayish-brown and dark- gray sandy loam extending to a depth of 60 inches or more. Seattle Muck-This soil series consists of very poorly drained organic soils that formed in material derived primarily from sedges. These soils are typically located in river and stream valleys. Slopes are 0 to 1 percent. The surface layer is a black muck about 11 inches thick. Below this is a dark reddish-brown,black,very dark brown,and dark-brown muck and mucky peat, extending to a depth of 60 inches or more. Everett-Alderwood Gravelly Sandy Loams—The Everett soil series are made up of somewhat • excessively drained soils that are underlain by gravelly sand at a depth of 18 to 36 inches. The Everett-Alderwood mapping unit is about equal parts of the Everett and Alderwood soil series. Alderwood soils are typically made up of moderately well drained soils. Bellingham Silt Loam—These soils are made up of poorly drained soils that formed in alluvium, under grass and sedges. The surface layer is a very dark brown silt loam about 11 inches thick. Below this, lies a mottled gray silty clay loam that is about 49 inches in depth. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. 5 A large, recent landslide occurred in the middle portion of the West Fork stream corridor, approximately 2,900 feet north of where Pacific Highway crosses Hylebos Creek. The landslide resulted in unstable soils in close proximity to the stream channel. There is also evidence of several additional, older landslides that have contributed sediment to the stream in the past. As a result, a series of gravel bars and terraces have formed in or near the creek downstream of these landslides. e. Describe the purpose,type, and approximate quantities of any filling or grading proposed. Indicate source of fill. No filling would occur as a result of the proposal. An abandoned garage-type building and several concrete foundations located on the east side of the stream would be removed near Station 25+50.This area will be replanted with riparian vegetation as part of the habitat restoration element of this project. f. Could erosion occur as a result of clearing,construction, or use? If so, generally describe. The purpose of the project is to control erosion, sediment transport in the stream and to enhance the habitat of the stream corridor. Blackberries and other invasive plant species currently cover approximately 0.6 acres in the area around the abandoned structure at Station 25+50 (refer to 1 e, above). This area will be cleared and revegetated with native riparian vegetation and upland forest species. In addition, 2.4 acres of riparian area along approximately 800 feet of the east streambank, upstream of South 356th Street, will also be cleared and revegetated with native riparian species. Finally, within the steeper ravine area, potted conifers will be planted by hand to re-establish a conifer forest along both sides of the stream, therefore improving slope stability. Some erosion could occur during the demolition and removal of the abandoned structure and foundations near Station 25+50. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The proposed project will not create any new impervious surfaces. h. Proposed measures to reduce or control erosion,or other impacts to the earth,if any. As previously mentioned,areas where invasive plants will be cleared, will be revegetated with • native riparian vegetation and upland forest plant species to provide long term erosion control. In addition, potted conifers will also be planted to re-establish a forest along both sides of the stream for approximately 1,200 feet. Silt fencing will be placed downslope from the demolition area at Station 25+50 to prevent movement of soil to the creek. Silt fencing will also be used downslope of the channel constructed for the fish ladder. The use of construction equipment will be limited to areas accessible using existing roads and driveways(refer to 12a). For areas of the creek not accessible by existing roads,the materials will be flown to each site by helicopter and assembled and placed by hand. This includes all of the 6 engineered log jams and several of the log revetments. No new roads or construction trails will be pioneered by this project,thus minimizing the potential for erosion. 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. Clearing and grading operations could result in temporary airborne dust particles during construction if soils are dry. Exhaust from diesel equipment,during the construction of bioengineering measures,will be minimal. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No off-site emissions or odors are evident that would affect this project. c. Proposed measures to reduce or control emissions or other impacts to air,if any. Dust control measures,such as wetting down soils,will be implemented at the two vegetation clearing sites, if necessary,during construction to minimize fugitive dust emissions. Construction equipment will be fitted with appropriate devices to control pollution that is generated in the form of exhaust. 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 West Fork of Hylebos Creek and its associated wetlands are the dominant surface water bodies within the proposed project area. Brook Lake,which is located in Hylebos State Park,is located just north of the project area.A small pond is located on the west side of the creek a short distance upstream of Pacific Highway South. There are several more ponds in the creek vicinity downstream of the highway. The West Fork of Hylebos Creek meets up with the East Fork of Hylebos Creek approximately 2 miles south of the project area. Hylebos Creek eventually flows into the Hylebos Waterway, a canal that connects to Commencement Bay in Tacoma. 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. 7 Construction of the proposed project will require work within and adjacent to the creek. The project includes a variety of bioengineering measures, aimed at stabilizing sediments within the channel. Measures include engineered log jams, weirs, and revetments. A total of twelve log jams,three log revetments, and three sets of log weirs will be placed in the channel between South 356th Street and Pacific Highway South. The purpose of the log weirs will be to improve fish passage at locations where there are substantial changes in channel grade. Log revetments are proposed to protect eroding streambanks, while log jams are engineered to trap channel sediment in place. An abandoned garage-type building and several concrete foundations(located on the east side of the stream in the southern portion of the project area)will be removed, along with 0.6 acres of blackberries and other invasive plants. This area will be replanted with native riparian vegetation and upland forest plant species. Another riparian area located at the northern end of the project area (upstream of South 356th Street)would be cleared and revegetated with riparian species. This area consists of 2.4 acres located along approximately 800 feet of the east streambank. Finally,within the ravine(middle portion)of the project area,conifers will be planted by hand to re-establish a conifer forest along both sides of the stream for approximately 1,200 feet. A fish ladder will be constructed providing fish access to the pond located upstream of Pacific Highway South. 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. No fill or dredge material will be placed in the West Fork of Hylebos Creek and or its associated wetlands. Minor bank excavation will occur during installation of the log weirs. Stream banks will be returned to their original contours after construction of the log weirs. Approximately 25 cubic yards of material will be removed from the right bank of the creek at the location where the fish ladder meets the creek. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose,and approximate quantities if known. The proposal will not require any surface water withdrawals or diversions. 5) Does the proposal lie within a 100-year floodplain? If so,note location on the site plan. The project area does not lie within a formally-designated 100-year 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. The proposal does not involve any discharges of waste materials to surface waters. b. Ground. 8 f Will ground water be withdrawn,or will-water be discharged to groundwater? Give general description,purpose, and approximate quantities if known. No ground water will be withdrawn,nor will water be discharged to ground water. 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. No waste material will be discharged into the ground. c. Water runoff(including storm water). 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 proposed project will occur within and along a stream corridor,which receives runoff from the Hylebos Creek Basin. This project will not increase the quantity of water running off from the site. Removal of an abandoned structure and several foundations will reduce,slightly,the amount of stormwater reaching the creek. The West Fork of Hylebos Creek joins the East Fork to form the main stem of Hylebos Creek,which eventually flows into Commencement Bay in the City of Tacoma. 2) Could waste materials enter ground or surface waters? If so,generally describe. No. d. Proposed measures to reduce or control surface,ground,and runoff water impacts,if any. The purpose of the project is to control sediment movement in the creek and to enhance habitat. In addition, invasive plants will be removed from two areas adjacent to the creek. These areas will be replanted with riparian vegetation and upland forest plant species aimed at reducing soil erosion caused from runoff, and improving habitat. 4. PLANTS a. Check or circle types of vegetation found on the site. X deciduous tree: alder, maple,aspen, other X evergreen tree: fir,cedar,pine, other X shrubs grass pasture 9 crop or grain X wet soil plants: cattail,buttercup,bulrush,skunk cabbage,other water plant: water lily, eelgrass, milfoil,other X other types of vegetation b. What kind and amount of vegetation will be removed or altered? Vegetation consisting of invasive species, such as blackberries,will be removed from two separate riparian areas. One area(0.6 acres) is located towards the southern portion of the project area where an existing abandoned garage and concrete foundations on the east side of the stream will be removed. The other area is approximately 2.4 acres in size, and is located at the northern end of the project area,just upstream of where South 356th Street crosses the West Fork of Hylebos Creek. c. List threatened or endangered species known to be on or near the site. There are no threatened or endangered plant species are anticipated to be on or near the site. A letter requesting a threatened and endangered species database search was sent to U.S. fish and Wildlife Service on December 12,2002 and to the Washington Department of Natural Resources, Natural Heritage Program on February 12,2003. No response has been received as of this publication date. d. Proposed landscaping,use of native plants,or other measures to preserve or enhance vegetation on the site,if any. Riparian areas will be replanted with a mixture of native vegetation and upland forest species. In addition,the middle portion of the project area,which contains the steepest slopes,will be planted with potted conifers,to re-establish a conifer forest along both sides of the stream. 5. ANIMALS a. Underline any birds and animals which have been observed on or near the site or are known to be on or near the site. X birds: hawk,heron, eagle,songbirds,other: ducks,pheasant, woodpeckers, and owls X mammals: deer, bear, elk, other: raccoons,coyotes,muskrats, squirrels,rabbits, and skunks. • X fish: bass,salmon,trout,herring, shellfish,other: Chinook,Coho,Chum, Cutthroat b. List any threatened or endangered species known to be on or near the site. Chinook salmon and potentially,the Bald Eagle and the Pileated Woodpecker, may inhabit the project area. A letter requesting a threatened and endangered species database search was sent to U.S. fish and Wildlife Service on December 12, 2002 and to the Washington Department of Fish and Wildlife on February 12, 2003. No response has been received as of this publication date. c. Is the site part of a migration route? If so,explain. 10 Yes, spawning salmonids have been documented in the West Fork of Hylebos Creek. In addition, the site is located within the Pacific Flyway Corridor, a significant route for migratory birds. d. Proposed measures to preserve or enhance wildlife, if any. Construction of the enhancement project will result in restored riparian habitat or habitat functions serving numerous species of wildlife. Invasive plant species will be removed in several areas. Native vegetation and conifers will be planted to improve riparian habitat and to help control erosion. Reducing the amount of sediment entering the stream will help to improve spawning conditions. The downstream-most log weirs near station 13+50 will help improve fish passage past a short, gabion-lined section of stream channel that has several small drops. The remaining log weirs and the engineered log jams are expected to create pools,which are largely lacking along this stretch of the stream,improving fish habitat. The fish ladder will provide fish access to a nearby pond,providing much-needed off-channel habitat and refuge. 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. The completed project will not require the use of energy. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. The project would not affect the potential use of solar energy by adjacent properties. 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. As the project will not require power,no energy conservation measures are proposed. 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 environmental health hazards will occur as a result of this proposal. 1) Describe special emergency services that might be required. No special emergency services will be required. 11 2) Proposed measures to reduce or control environmental health hazards,if any. No such measures are proposed. b. Noise. 1) What types of noise exist in the area which may affect your project(for example: traffic, equipment operation,other)? The primary source of noise in the project area is car and truck traffic noise generated from vehicular use of local roads and Pacific Highway South. However,this noise is not expected to affect the project. 2) What types and levels of noise would be created by or associated with the project on a short- term or long-term basis(for example: traffic,construction operation,other)? Indicate what hours noise would come from the site. Construction of the proposed project would generate temporary noise increases from construction equipment.Actual noise levels during construction will vary depending on the type of equipment used. Construction equipment including backhoes, small cranes,dump trucks and delivery trucks will be used to construct the log weirs and the fish ladder. A private school would experience increased noise levels during installation of one of the log weir sets and the fish ladder. This would last only during active construction,estimated to be no more than two weeks at this location. Placement of the logs for the engineered log jams and one or more of the log revetments, will be carried out by helicopter.No homes or other occupied buildings would be over-flown by the helicopter. A single residence lies in the vicinity of the path the helicopter would take to deliver materials. Helicopter operations would last from one to three days No noise will be associated with the project on a long-term basis. 3) Proposed measures to reduce or control noise impacts,if any. Mitigation measures to reduce or control noise impacts from construction activities would include: • All construction equipment used shall have sound control devices no less effective than those provided on the original equipment.No equipment shall have unmuffled exhaust. • All construction activities shall meet federal, state, and local noise standards. • Adjacent property owners will be notified ahead of time when helicopter operations are scheduled. 8. LAND AND SHORELINE USE 12 a. What is the current use of the site and adjacent properties? The current use of the site is generally open space in the form of wetlands,and a drainage corridor because much of the project area lies within wetlands and a steep ravine. Adjacent lands consist mostly of large, wooded lots. One residence is located near the stream, itself,near Station 44+00. A private grade school is located adjacent to the stream,just upstream of Pacific Highway South. A church and private grade school are located near the creek crossing of South 356th Street. The northern portion of the project site consists of lands owned by the City,upstream and downstream of South 356th Street. Immediately upstream of these City-owned lands is West Hylebos State Park. b. Has the site been used for agriculture? If so,describe. A blueberry farm currently exists just north of South 356th Street,at the northern end of the project site.This farm was abandoned,but casual harvesting of the blueberries by local residents still occurs. One of the proposed replanting locations will occur in this area, some of the existing blueberry bushes near the creek may be removed. c. Describe any structures on the site. An abandoned garage-type building and several concrete foundations are located on the east side of the stream near Station 25+50. d. Will any structures be demolished? If so,what? Yes,an abandoned garage-type building and several concrete foundations(mentioned in 8c, above) will be removed. e. What is the current zoning classification of the site? The project site is located in three single-family residential zones: RS35.0(minimum lot size 35,000 SF),RS9.6 (minimum lot size 9,600 SF), and SE (Suburban Estate). f. What is the current comprehensive plan designation of the site? The current comprehensive plan designation for the majority of the site is single family, low- density. A small portion of the project area, located north of South 356th, is designated as parks and open space. g. If applicable,what is the current shoreline master program designation of the site? The proposed project site is not within the jurisdiction of the shoreline master program. h. Has any part of the site been classified as an "environmentally sensitive" area? If so,specify. A large portion of the project area includes wetlands that have been documented on the City of Federal Way Critical Areas Map. The entire project site is located in areas that have a high or medium susceptibility to groundwater contamination according to Map IX-1 of the City of Federal 13 Way Comprehensive Plan. Map IX-2 of the comprehensive plan,Surface Water Resources, shows numerous wetlands within the proposed project area. In addition,the stream corridor has also been noted on the City of Federal Way Priority Habitats and Species Map(map number IX-4). i. Approximately how many people would reside or work in the completed project? Not applicable. j. Approximately how many people would the completed project displace? The proposed project would not displace any people. k. Proposed measures to avoid or reduce displacement impacts,if any. Not applicable. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans,if any. The purpose of the proposed project is to enhance the existing stream and riparian habitat of the West Fork of Hylebos Creek and to control the movement of sediment in the streambed. Since no buildings or new impervious surfaces are proposed,the project is consistent with the comprehensive plan's"open space"and"low density single-family" designations. 9. HOUSING a. Approximately how many units would be provided, if any? Indicate whether high, middle,or low-income housing. None. b. Approximately how many units,if any,would be eliminated? Indicate whether high,middle, or low-income housing. None. c: Proposed measures to reduce or control housing impacts,if any. Not applicable 10. AESTHETICS a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s)proposed? 14 No structures will be built on the project site. b. What views in the immediate vicinity would be altered or obstructed? No views would be altered or obstructed. c. Proposed measures to reduce or control aesthetic impacts,if any. Areas where invasive vegetation will be cleared and removed will be revegetated with native plants and riparian species that improve habitat function. The aesthetics of these areas will also be improved. 11. LIGHT AND GLARE a. What type of light or glare will the proposal produce? What time of day would it mainly occur? Lights will not be installed at the project site. b. Could light or glare from the finished project be a safety hazard or interfere with views? No. 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. No measures are needed. 12. RECREATION a. What designated and informal recreational opportunities are in the immediate vicinity? While the majority of the project area is privately owned, a 68-acre day-use park called the West Hylebos Wetlands State Park is located just to the north of the project area. The State Park offers a variety of recreational opportunities including hiking, bird watching, interpretive activities,and wildlife viewing. City-owned land along the creek north of South 356th Street includes an old blueberry farm and open space,open to access by the public. b. Would the proposed project displace any existing recreational uses? If so, describe. 15 No. The area to be cleared and revegetated north of South 356th Street includes a portion of the old blueberry farm. Some of the blueberry plants may be removed,but this will not substantially impact the casual blueberry harvesting enjoyed by some of the local residents. c. Proposed measures to reduce or control impacts on recreation,including recreation opportunities to be provided by the project or applicant,if any. No measures have been identified, as the project will not impact recreational activities in the area. 13. HISTORIC AND CULTURAL PRESERVATION a. Are there any places or objects listed on, or proposed for,nation,state,or local preservation registers known to be on or next to the site? If so,generally describe. The Federal Way Historical Tour Guide identifies three local historic resources that are located near the proposed project site: • Historical Cabins Park—located at 4th Avenue South and South 348th St. • Brooklake Community Center(est.1920)—located at 726 South 356th St. • Andrew Jerstadt Farm(est.1911)—located at 215 South 373`d St. According to staff at the Federal Way Historical Society,none of the above mentioned historic resources are listed on the state or federal register of historic places, nor have these been submitted to King County for landmark designation. b. Generally describe any landmarks or evidence of historic,archaeological,scientific,or cultural importance known to be on or next to the site. According to staff at the Federal Way Historical Society,no objects of historic or archaeological significance have been found or documented within the West Fork of Hylebos Creek. However,the West Hylebos Wetlands State Park(located north of the proposed project area) is historically and culturally significant. The park is an important resource for education about the geologic and scientific history of the area. A significant number of students visit the park each year and learn about the area through an interpretive trail. In addition, the above mentioned Historical Cabins Park acts as an entrance to the West Hylebos Wetlands State Park. c. Proposed measures to reduce or control impacts, if any. No impacts to historic or cultural resources are expected,therefore,no measures are proposed. However, if any potential historic or cultural resources of significance are encountered on or adjacent to the proposed project property, the Washington State Office of Archeology and Historic Preservation(OAHP) would be notified immediately. 14. TRANSPORTATION 16 a. Identify public streets and highways serving the site,and describe proposed access to the existing street system. Show on site plans,if any. South 356th Street and Pacific Highway South are the two major roads serving the site. Three driveways will also provide access to the stream corridor for construction equipment. One of these driveways currently serves the Montessori School while a second driveway serves a residence located near the stream at Station 44+00. A third driveway,which used to provide access to a now abandoned house,has since become overgrown with vegetation. This driveway will be cleared of vegetation and utilized for access the stream corridor. After construction of the log weirs,this area will be replanted to restore/improve habitat conditions. b. Is the site currently served by public transit? If not,what is the approximate distance to the nearest transit stop? The site is located in close proximity to Pacific Highway South,which is served by a number of Metro public transit buses. c. How many parking spaces would the completed project have? How many would the project eliminate? The project does not propose any new parking spaces.No parking spaces would be eliminated. d. Will the proposal require any new roads or streets,or improvements to existing roads or streets,not including driveways? If so,generally describe(indicate whether public or private). The proposed project will not require any new roads or streets, or improvements to existing roads or streets. e. Will the project use(or occur in the immediate vicinity of)water, rail, or air transportation? If so,generally describe. Yes,the project requires air transportation in the form of a helicopter on a temporary basis. The helicopter will be used to deliver some of the construction materials,thus avoiding the need to pioneer new roads into the project area. The helicopter will transport and place logs for the engineered log jams and revetments. f. How many vehicular trips per day would be generated by the completed project? If known, indicate when peak volumes would occur. The proposed project will not generate an increased number of vehicular trips. g. Proposed measures to reduce or control transportation impacts,if any. Traffic control will be proposed on South 356th Street and Pacific Highway South as needed for the delivery of materials and for transport of construction equipment. City staff will notify residents 17 adjacent to the site of the day and approximate time period that the helicopter is scheduled to drop off materials. It is expected that the staging area will be near the project site and that the helicopter will not over-fly any home or public road during delivery operations. No long-term transportation impacts will occur as a result of the project. 15. PUBLIC SERVICES a. Would the project result in an increased need for public services (for example: fire protection, police protection, health care,schools, other)? If so,generally describe. The project will not result in an increased need for public services. b. Proposed measures to reduce or control direct impacts on public services,if any. No measures are proposed. 16. UTILITIES a. Underline utilities currently available at the site: electricity,natural gas,water,refuse service, telephone,sanitary sewer,septic system, other. b. Describe the utilities that are proposed for the project,the utility providing the service,and the general construction activities on the site or in the immediate vicinity which might be needed. No utilities are proposed for project. C. SIGNATURE The above answers are true and complete to the best of my knowledge. I understand that the lead agency is relying on them to make its decision.

Per FWCC 22-1311, "The director of community development may permit or require the applicant to rehabilitate or maintain a stream by requiring the removal of detrimental materials such as debris, sediment and invasive, non-native vegetation." This letter is to request an approval from the director of community development for this referenced project. One difference from our conversations is that the project will not be constructing the pond connection at this time due to ongoing technical discussions with WSDFW. Attached are the 80% design drawings that have been developed recently and more detailed project analysis in accordance with the FWCC 22-1311 requirements. Please evaluate the information and make your determination. Sincerely, Fei Tang, P.E. SWM Project Engineer CC: Paul Bucich, P.E., SWM manager Project File Day File West Hylebos Creek Restoration Project Analysis Background The project proposes habitat improvements and sediment control measures for the West Fork of Hylebos Creek. The project area is located in the southern portion of the City of Federal Way. The project proposes habitat improvements and sediment control measures for an approximately one mile-long stretch of the West Fork of Hylebos Creek. The northern boundary of the project area is located approximately 800 feet north of South 356th Street and the southern boundary is where Pacific Highway South(Highway 99)crosses the West Fork of Hylebos Creek(see attached vicinity map). Existing Condition and Sources of Degradation The West Fork of Hylebos Creek has a high sediment load that tends to deposit downstream of Pacific Highway South (Highway 99). This impacts fish habitat and contributes to frequent flooding at an existing bridge at S. 373`d Street. Investigation has identified several sources of sediment in a one-mile stretch of the creek upstream of Pacific Highway South. A large, recent landslide has placed unstable soils in proximity to the stream channel. There is evidence of several additional, older landslides that have contributed sediment to the stream in the past. A series of gravel bars and terraces have formed downstream of these landslides. It is likely that high stream flows readily mobilize these features, moving large amounts of sediment downstream. In addition,there are a number of exposed streambanks which contribute lesser amounts of sediment to the stream. Most of the area along this stretch of the stream lies within a forested ravine. It is not accessible by road. Therefore, a conventional, large-scale slope stabilization project is not feasible. Instead the strategy behind this project is to stabilize sediment in place and reduce the excessive downstream movement of sediment, to the extent practical, emphasizing the use of bio-engineering measures. Proposed Actions The project will consist of a series of engineered log jams and log weirs to stabilize the stream channel and trap channel sediment in place (Figure 2). Three sets of three to five log weirs are proposed in the vicinity of Stations 13+50, 18+00 and 25+00. (The stations refer to feet above the stream crossing(plus 1,000)at Pacific Highway South. For instance, Station 13+50 is located 350 feet upstream of the highway.) There are several sizable drops in the channel grade at the bridge at Station 13+50. The primary purpose of the five log weirs at this location would be to improve fish passage. Twelve engineered log jams are proposed between Stations 20+00 and 41+00. Three log revetments(short logs pinned together)are proposed to protect eroding streambanks: two between Stations 24+00 and 25+00 and one at Station 41+50. An abandoned garage-type building and several concrete foundations located on the east side of the stream near Station 25+50,would be removed. Blackberries and other invasive plant species currently cover approximately 0.6 acres in this area. This area would be cleared and revegetated with native riparian vegetation and upland forest species. In addition,2.4 acres of riparian area along approximately 800 feet of the east streambank,upstream of South 356th Street,would also be cleared and revegetated with native riparian species.Up to two dozen fabricated "ELWd"logs may be installed in this area by a stream advocacy group: Friends of the Hylebos Wetlands. Finally, within the ravine area,potted conifers would be planted by hand to re-establish a conifer forest along both sides of the stream, between Stations 28+00 and 40+00. There is road access to the sites proposed for the log weirs and clearing/revegetation, allowing for construction equipment access. The materials for the engineered log jams and one or more of the log revetments would be delivered by helicopter and assembled and placed by hand, avoiding the need to pioneer new roads into the project area. Sediment/erosion control measures utilizing Best Management Practices as outlined in the King County Surface Water Design Manual will be in place during construction to aid in minimizing potential water quality impacts. Areas where invasive plants will be cleared,will be revegetated with native riparian vegetation and upland forest plant species to provide long term erosion control. In addition, potted conifers will also be planted to re-establish a forest along both sides of the stream for approximately 1,200 feet. Silt fencing will be placed downslope from the demolition area at Station 25+50 to prevent movement of soil to the creek. Silt fencing will also be used downslope of the channel constructed for the fish ladder. The use of construction equipment will be limited to areas accessible using existing roads and driveways(refer to 12a). For areas of the creek not accessible by existing roads,the materials will be flown to each site by helicopter and assembled and placed by hand. This includes all of the engineered log jams and several of the log revetments. No new roads or construction trails will be pioneered by this project, thus minimizing the potential for erosion. Monitoring Plan Monitoring plan for this project has been developed and the draft plan is attached for your review.

The project focuses on three goals: • Trap and attenuate excessive gravel bed load that is depositing downstream of Pacific Highway South. • Improve in-stream habitat • Improve stream buffer habitat in selected areas. These goals will be accomplished through installation of in-stream structures,enhancement of existing hardwood forest and shrubland riparian areas through planting of conifers,and selective control of invasive shrubs and replacement with native shrub and tree species. This monitoring plan details the approaches to be used to measure the degree to which each of these measures meets project goals.The schedule of the plan will also help assure that the performance of these measures is observed on a timely basis and that maintenance and/or adjustments are made, as necessary,to assure their success. Instream Measures The instream measures include installation of three clusters of log weirs,with a total of 11 individual weirs (in upstream order: 5-3-3), 12 engineered log jams and 3 log revetments. The first two measures are intended to trap and attenuate bed load sediment and improve stream habitat through additional refuge habitat and creation of new pools and riffles. The log revetments will reduce sediment discharge in three areas where the streambank is actively eroding. In-Stream Monitoring Methods The effectiveness of each structure will be evaluated after installation. One photo station (marked by a fence post fence post)will be installed at each site. Each of these sites will be photographed before and immediately after installation of the structure. Following construction, the channel cross-section will be surveyed at a point 5 feet upstream of the upstream end of the installed structure. These sites will then be periodically re-visited. After the first significant rainfall accumulation of 5 inches occurring after November 1 (following construction),each site will be visited and inspected,and each structure will be re-photographed. The purpose will be to determine if there has been any substantial shift or movement of any of the structures following the first substantial stream flows and to determine their early effectiveness in trapping gravel. Thereafter,each site will be visited annually,in early June,following the end of the Wet Season. Photographs will be taken from each photo station. Channel cross sections will be K:ISWM\PROJECTS\WHYLEBOS RESTORATION\DESIGN\REPORTS\MONITOR1.DOC • surveyed. Notes will be taken on key observations. These include observations of sediment accumulation,pool formation, signs of streambank erosion, observations of fish,etc. Any signs of significant movement or failure of a structure will noted, as well. A brief report will be prepared summarizing the observations. The report will contain recommendations for needed repairs or field adjustments of the structures. This report will be prepared by the end of June,allowing ample time for repairs (if necessary) during the remainder of the Dry Season. The channel cross-sections can be surveyed using a rod and a hand-held bubble-level. These measurements will be made in close proximity and only relative elevations are needed. Therefore, this simple survey method is adequate and provides for reasonably rapid and efficient acquisition of comparable cross-section data. Riparian Habitat Enhancement Measures Approximately 550 conifers will be planted in a four-acre conifer planting area along both sides of a portion of the West Fork. In addition, two other sites will undergo major revegetation work: the Pacific Highway South and the South 356th Street Revegetation Areas. Himalayan blackberry and other exotic blackberries and invasive native shrubs will be removed, or otherwise controlled. The habitat will be enhanced through planting of over 300 native conifers and over 2,300 native shrubs.Over time,the restoration of a conifer overstory and the reduction of invasive shrubs will add shade to the stream (reducing temperatures) and provide a source of natural large woody debris. Habitat Enhancement Monitoring Methods The habitat enhancement monitoring is to be performed on or before the date of the in- stream monitoring, discussed above. After tree planting in the conifer planting area,a random, stratified subset of 0 percent of trees within the four-acre conifer planting area (approximately 55 cedar and 55 hemlock seedlings) shall have an anodized aluminum tag attached with a unique identification number and latitude-longitude coordinates obtained via hand-held GPS(to the extent possible within the forest canopy). Each Spring, these tagged trees will be revisited (using GPS coordinates to navigate to them). The mortality of these trees shall be noted. Tree mortality shall be summarized by species. The Pacific Highway South and the South 356th Street Revegetation Areas will also be visited. The general health and growth of the installed plants will be documented. The mortality among the installed plants will also be determined through sub-sampling of the planted areas. The sub-sampling program will be specifically defined after the areas have been revegetated. It is envisioned that sub-sampling will occur along three randomly selected strip transects across each site. Along each strip transect,all planted seedlings on 10 feet to either side of the centerline will be observed and mortality of plants recorded. Where mortality exceeds 20% of the previous year's plants,recommendations will be made with regard to replacement plantings. Areas where invasive species are actively gaining a foothold will be noted. This information will be documented in the annual Monitoring Report discussed above, along with recommendations for revegetation and/or removal of invasives. Monitoring Period The monitoring period will extend over a period of five years following construction. An annual monitoring report will be prepared by July 30 of each year. The report will document field observations,recommend adaptive management measures, and document the degree of success of the measures. The report will identify any maintenance or corrective measures which need to be accomplished during the current Dry Season. The fifth and final monitoring report shall contain an overall evaluation of the effectiveness of the measures and recommendations for changes which would further enhance the effectiveness of similar projects in the future.

We have determined that the proposal will not have a probable significant adverse impact on the environment. As a result, an Environmental Impact Statement(EIS) is not required to comply with the State Environmental Policy Act(SEPA). A copy of the Determination of Nonsignificance (DNS) is enclosed. A 14-day comment period is required by the SEPA Rules (WAC 197-11-340). A notice inviting comments will be published in the Federal Way Mirror on April 12, 2003. At the end of the comment period,the Department will determine if the DNS should be issued as proposed,withdrawn, or modified. All final determinations may be appealed within 14 days following the comment deadline. No licenses, permits, or approvals will be issued until completion of the appeal period. Our decision not to require an EIS does not mean that the license,permit, or approval you are seeking from the City has been granted. Approval or denial of the proposal will be made by the appropriate administrative or legislative body vested with that authority. The environmental record is considered by the decision maker(s)and conditions will be imposed to reduce identified environmental impacts, as long as the conditions are based on adopted and designated City policy. Mr. Paul Bucich Page 2 April 11, 2003 After a final decision has been made on your proposal (i.e., after an approval or permit has been issued or City Council action taken, as applicable), you may, but are not required to,publish a Notice of Action as set forth in RCW 43.21 C.075. The Notice of Action sets forth a time period after which no legal challenges regarding the proposal's compliance with SEPA can be made. A copy of the Notice of Action form and copies of RCW 43.21C.080 and WAC 197-11-680 providing instructions for giving this notice are available from the Department of Community Development. The City is not responsible for publishing the Notice of Action. However, the City is responsible for giving a notice (to parties of record) stating the date for commencing a judicial appeal (including the SEPA portion of that appeal) if your proposal is one for which the City's action on it has a specified time period within which any court appeals must be made.

The West Fork of the Hylebos Creek has a high sediment load that tends to deposit downstream of Pacific Highway South. This impacts fish habitat and contributes to frequent flooding at an existing bridge at South 373`d Street. The City's investigation has identified several sources of sediment in a one-mile stretch of the creek upstream of Pacific Highway South. A recent large landslide has placed unstable soils in proximity to the creek channel. There is evidence of several other older landslides that have also contributed sediment to the creek. A series of gravel bars and terraces have formed downstream of these landslides. It is likely that high in-stream flows mobilize these features,moving sediment downstream. Additionally,there are a number of exposed stream banks that also contribute sediment to the creek. The portion of the creek where the sedimentation originates extends from the southerly end of the West Hylebos Wetlands State Park,south to the point where the creek meets Pacific Highway South. 2. The project is to make habitat improvements and implement sediment control measures on the segment of the West Fork of the Hylebos Creek identified above.The project consists of a series of engineered logjams and log weirs to stabilize the stream channel and trap channel sediment in place. An abandoned garage type building will be removed and several concrete foundations located on the east side of the creek will be removed. Blackberries and other invasive plant species will be cleared and the area revegetated with native riparian vegetation and upland forest species. Within the ravine area, potted conifers will be planted by hand to re-establish a conifer forest along both sides of a section of the creek. The original proposal,which underwent environmental review under SEPA, included the following component: there is a two-abre pond adjacent to the creek which discharges to the creek via two small(10 & 12 inches)plastic pipes. These pipes will be removed and a fish ladder constructed to provide fish access to this pond. However,the fisheries biologist from the Washington State Department of Fish and Wildlife(WDFW)questioned the feasibility of this component and suggested that the City monitor the flow and water quality of the pond before undertaking any construction. Therefore,this component has been removed from the 80 percent plans and is not'a component of this application(File No. 03-101298-00-AD), but it is a component of the SEPA threshold determination(File No. 03-101023-00-SE). The flow and water quality of the pond will be monitored for a year and the monitoring data provided to WDFW. If the monitoring data indicates that the pond would provide habitat,the removal of the pipes and construction of a fish ladder will be a separate project, subject to this administrative review process prior to construction. 3. Environmental review pursuant to SEPA was completed under City File No. 03-101023-00-SE. A Determination of Nonsignificance (DNS)was issued by the City of Federal Way on April 11,2003. A Notice of Environmental Determination inviting public comments was published in the Federal Way Mirror on April 12,2003, in accordance with code requirements. The notice indicated that a DNS was issued for the proposal.A 14-day comment period followed the Notice of Environmental Determination. The comment period ended on April 28, 2003.No comment letters were received during the comment period. The appeal period for this determination was completed on May 12, 2003,with no appeals filed. The Final Staff Evaluation for Environmental Checklist is hereby incorporated by reference as though set forth in full. 4. Construction is proposed in a manner to minimize erosion, sedimentation,and disturbance of the stream and riparian habitat. All disturbed areas will be restored pursuant to the submitted plans. Within 30 days of completing the project,all disturbed areas must be restored in accordance with the approved plan.Upon completion,the applicant must request final inspection from the Department of Community Development Services. Revegetation measures shall be inspected to ensure compliance with the approved plan and FWCC Sections 22-1564 and 22-1095,to the maximum extent possible. 5. The project will be constructed by the City of Federal Way. The subject application, City File No. 03-101298-00-AD,was submitted for review on April 2, 2003. The proposal is classified as a stream rehabilitation project and has been under the requirements if FWCC Section 22-1311, and the related May 9, 1996, stream rehabilitation code interpretation. The proposed stream rehabilitation/restoration requires approval by the Director of Community Development Services by an administrative decision pursuant to the following criteria: The Director of Community Development may permit or require the applicant to rehabilitate or maintain a stream by requiring the removal of detrimental materials such as debris, sediment, and invasive, non-native vegetation. Approval of stream rehabilitation shall be based on a review of a plan containing, at a minimum, an analysis of existing conditions, identification of the source, if possible, of the degradation of the stream or riparian zone;proposed corrective actions, including installation of native species within the riparian corridor;performance standards; monitoring schedule;planting plans; erosion and sedimentation control plans; and grading plans as necessary. The director shall require an applicant to retain the services of a qualified professional in preparing the restoration plan. These actions may be permitted or required at any time that a condition detrimental to water quality, stability of stream banks, degradation of existing naturally vegetated buffers, or in stream habitat exists. Intrusions into regulated steep slopes and associated setbacks will be allowed for purposes of approved stream rehabilitation projects(FWCC Section 22-1311). The interpretation states that stream rehabilitation maybe,allowed if the proposal will enhance stream functions and habitat values, or reduce or stabilize erosion, sedimentation, or stream flow, as determined by the Director of Community Development Services. Stream rehabilitation is hereby defined to include improvements that revitalize or reestablish characteristics and processes diminished or lost by past alterations, activities, West Hylebos Creek Restoration Project File#03-101298-00-AD/Doc[D 23140 Findings of Fact&Analysis of Decisional Criteria Page 2 or catastrophic events, and/or alteration of an existing stream to improve or increase its functions and values without degrading other existing functions. Stream rehabilitation specifically excludes improvements related solely to improving surface water conveyance (e.g. culverts) (May 9, 1996,Interpretation). Response: As previously indicated,the segment West Fork of the Hylebos Creek in question has a high sediment load that tends to deposit downstream of Pacific Highway South.This impacts fish habitat and contributes to frequent flooding at an existing bridge at South 373' Street. The proposed restoration project has three goals: • Trap and attenuate excessive gravel bed load that is depositing downstream of Pacific Highway South • Improve in-stream habitat • Improve stream buffer habitat in selected areas These goals will be accomplished through the installation of in-stream structures,enhancement of the existing hardwood forest and shrub land riparian areas through the planting of native conifers, and selective control of invasive shrubs and replacement with native shrub and tree species. Sediment/erosion control measures utilizing Best Management Practices as outlined in the King County Surface Water Design Manual will be in place during construction to minimize the potential for adverse water quality impacts. The use of construction equipment will be limited to areas accessible using existing roads and driveways. The majority of the engineered logjams and revetments will be assembled and placed by hand using materials transported to the site via helicopter.A monitoring plan is proposed which will evaluate the effectiveness of each structure after installation and all plantings over a five-year period. Additional repairs and/or field adjustments of the structures, and revegetation and/or removal of invasive species, will be carried out over the monitoring period as needed. Based on the above,the proposed stream restoration(rehabilitation)will enhance stream functions and fish habitat values by providing additional refuge habitat and the creation of new polls and riffles associated with the in-stream structures. The proposed restoration project will also stabilize and reduce erosion and sedimentation. 6. A construction and staging area must be designated on the plans. Construction vehicle and equipment servicing and maintenance shall occur only within a designated construction and staging area to avoid potential stream impacts from petrochemical contamination. 7 The proposal is consistent with the comprehensive plan; all applicable provisions of FWCC Chapter 22; and the public health, safety, and welfare. Streets and utilities in the area of the subject property are adequate to serve the anticipated demand from the proposal, and access to the subject property is at the optimal location. Thus,the project meets all the requirements of FWCC Section 22-1311 and the related May 9, 1996, stream rehabilitation zoning interpretation. 8. This decision shall not waive compliance with future City of Federal Way codes,policies, and standards relating to this development. - West Hylebos Creek Restoration Project File#03-101298-00-AD/Doc ID 23140 Findings of Fact&Analysis of Decisional Criteria Page 3 CONCLUSION The proposal has been reviewed for compliance with the Federal Way City Code and Federal Way Comprehensive Plan,and other applicable city codes, plans, policies, and regulations. The proposal has been found to meet the requirements if FWCC Section 22-1311 and the related May 9, 1996, stream rehabilitation zoning interpretation,provided all conditions of project approval are met. Based on the findings and conclusions of this review,project approval with conditions is recommended.
