The wetland assessment and delineation was done using the methodology described in the following references: US Army Corps of Engineers Wetland Delineation Manual (1987), Regional Supplement to the Corps of Engineers Wetland Delineation Manual, Western Mountains, Valleys, and Coastal Region Version 2.0 (2010), and the Washington State Wetland Identification and Delineation Manual (1987). The assessment also referenced the King County GIS data, iMap, the Washington State DENR Forest Practices Application Review (FPARS), the USDA Soil Conservation Service Soil Survey for King County, Washington State, and the NRCS Web Soil Survey website. The results of the wetland showed the presence of wetland on the subject property. Wetland indicators identified in the sample locations include the presence of hydrophytic vegetation, hydric soil, and wetland hydrology. These are described in detail in the report. Using the 2014 Version of the Wetland Rating System for Western Washington, the wetland is rated as a Category III with a total function score of 19 points and a habitat score of 4 points. According to the Federal Way Revised Code Chapter 19.145.420.2, a Category III wetland with a habitat score of 3-5 points shall have a buffer width of 80 feet, measured from the edge of the wetland. An off -site stream is mapped to the east of the subject parcels. The stream is classified in the FPARS map as a Type F stream. Type F streams are stream that contains fish habitat (Federal Way Revised Code 19.145.260.2.b). According to the Federal Way Revised Code Chapter 19.145.270.1.a - Stream Buffers Type F stream shall have a buffer width of 100 ft measured from the Ordinary High Water Mark (OHWM) 1 � Midway Samoan Assembly of God Church Property Wetland Study _ November 2019 1.0 Project Description This study was conducted to determine the type of wetlands and streams on and near the site. The applicant is proposing to submit a building permit application for site development. 2.0 Site Address, Identification, and Directions The property is located at 29276 Military Rd. S., Federal Way, WA 98003 in King County, Washington (Figure 1). The site is located within the legal geographic description of northeast Section 04; Township 21; Range 04 East within the watershed of Duwamish-Green River and WRIA 9 (Duwamish-Green River). Directions to the site from DPER in Snoqualmie are as follows: 1. Head northwest toward S 333rd St.; 2. Turn left onto S 333rd St.; 3. Turn right onto 1 st Way S.; 4. Turn right onto S 312th St.; 5. Turn left onto Pacific Hwy S.; 6. Turn right onto S 304th St.; 7. Turn left onto Military Rd S.; Destination will be on the right 29276 Military Rd S. 3.0 Methodology The wetland assessment and delineation were performed using the Routine Methodology as described in Part IV, Section D of the Corps of Engineers Wetlands Delineation Manual (COE, 1987), Regional Supplement to the Corps of Engineers Wetland Delineation Manual Western Mountains, Valleys, and Coast Region (Version 2.0) (U.S.ACE, 2010), and the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). The wetland determination was based on the presence of the three criteria for jurisdictional wetlands; hydric soils, wetland hydrology, and hydrophytic vegetation. All three criteria must be present in order to classify an area as a wetland. The assessment includes a review of the King County GIS Data, the Department of Natural Resources Forest Practices Application Review System (FPARS) and the USDA Soil Conservation Service's Soil Survey of the King County Area, Washington (Snyder, et. al., 1973) and the NRCS web soil survey. The field investigation was conducted on October 26 and 27, 2018. Wetland boundaries were delineated by putting wooden stakes with orange wetland flags tied to it. 4.0 General Site Description There are two parcels on the project site. The parcel 042104-9063 is approximately 86,684 sq. ft. parcel 042104-9032 is approximately 21,344 sq. ft. Both parcels have building structures at the southwest corners of the property. The parcels are bound by Military Road S. to the west and single-family homes to the east, south, and north. The northeast of the larger parcel is populated with trees, shrubs, and herbaceous plant species. An off -site stream to the east of the property is mapped in the King County iMap. The mapped stream is actually dry and stream channel including the berm is mowed regularly. 2 Midway Samoan Assembly of God Church Property Wetland Study November 2019 The parcel has a vegetated area to the northeast corner populated with old mature tree of Pacific willows, reed canary grass, creeping buttercup, and traces of Himalayan blackberry. � F 0 Camelot j Squore Mobile / �5 A � ome Park a 6 Sir G31C �47 South 2%th Street 1 \.67'.0 / ru�a�.��ctF��teom„8tc Figure 1. Vicinity Map of Project Site (cyan parcel line) (Courtesy of King County iMap, 2017). 5.0 Vegetation 5.1 Determination of Hydrophtic Vegetation Hydrophytic vegetation has adaptations that allow these species to survive in saturated or inundated environments. These environments are classified according to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, 1979). The probability of species being found in wetland environments has been determined by the U.S. Fish and Wildlife Service in the National List of Vascular Species that Occur in Wetlands: 1996 National Summary (USFWS, 1996). An indicator status was applied to each species according to its probability of occurring in wetlands (see Table 1). 3 1 Midway Samoan Assembly of God Church Property Wetland Study November 2019 Table 1.0 Plant Indicator Status Indicator Category Symbol Occurrence in Wetlands Obligate Wetland OBL > 99% Facultative Wetland FACW 67-99% Facultative FAC 34-67% Facultative Upland FACU 1-33% Upland UPL < 1 % Note: FACW, FAC, and FACU have + and — values to represent species near the wetter end of the spectrum (+) and the drier end of the spectrum (-) (USFWS, 1996). Vegetation data was recorded at three sample locations. Hydrophytic vegetation at each sample locations were determined using the hydrophytic vegetation indicators established by the US Army Corps of Engineers, Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region Version 2.0 (2010) and the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). 5.2 Vegetation Results At sample location 1 (SL-1), the plant community is dominated by reed canary grass Phalaris arundinacea, FACW). The plant community is hydrophytic applying the Rapid Test and Dominance Test for hydrophytic vegetation. (see Data Form #1). At SL-2, the plant community is dominated by Pacific willow (Salic lucida var. lasiandra, (FACW+), creeping buttercup (Ranunculus repens, (FACW) and reed canary grass (Phalaris arundinacea, FACW). The plant community is hydrophytic using the Rapid Test and Dominance Test for hydrophytic vegetation. (see Data Form # 2). At SL-3, the plant community is dominated by mixed grass species, Graminae sp.(FAC). Grasses in western Washington are typically tolerant of wet conditions, therefore the unidentified grasses are assumed to be FAC. The plant community is hydrophytic using the Rapid Test and Dominance Test for hydrophytic vegetation. (see Data Form 3) 6.0 Soils 6.1 Determination of Hydric Soils The presence or absence of hydric soils were determined using the Field Indicators Guide to Hydric Soils in the United States Version 8 (2016) and the hydric soils indicators guide described in the US Army Corps of Engineers. 2010. Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region Version 2.0 Hydric soils are soils that are "saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (COE, 1987)". They are either organic soils (peats and mucks), or are mineral soils that are saturated long enough to produce soil properties associated with a reducing environment. These soils 4 � Midway Samoan Assembly of God Church Property Wetland Study November 2019 have hydric characteristics such as a reduced matrix (a matrix that changes color when exposed to air), redox depletions (gleying), or redox concentrations (mottles). Soils at each sample were assessed for organic content and hydric characteristics in a 20-inch deep soil pit at each sample location. In Washington State, soil color is the main indicator used to determine if a soil is considered hydric. Soil color immediately below the "A" horizon or at a depth of 10 inches below ground surface was determined using Munsell Soil Color Charts (MacBeth, 2000). Soils that had a one-chroma matrix or a two-chroma matrix with mottles were determined to be hydric. 6.2 Soil Survey Series The USDA Soil Conservation Service (SCS) mapped this area of King County as Orcas peat (Or) (Figure 2). The Orcas series is made up of very poorly drained organic soils that formed in sphagnum moss and small amounts of Labrador tea and cranberry plants. In a representative profile, the surface layer is dark reddish -brown sphagnum peat about 6 inches thick. The next layer is yellowish -red sphagnum peat that extends to a depth of about 60 inches Representative profile of Orcas peat, under wild cranberries, 600 feet north and 650 feet west of the east quarter corner of sec. 8, T. 24 N., R. 6 E.: Oil­0to 6 inches, dark reddish -brown (5YR 3/2) sphagnum peat, very pale brown (10YR 7/3) dry; soft, spongy; many roots; extremely acid; clear, smooth boundary. 6 to 8 inches thick. Oi2--6 to 60 inches, yellowish -red (5YR 5/6, 4/6, 4/8) sphagnum peat, very pale brown (10YR 7/4) dry; soft, spongy; few roots; extremely acid. Some areas mapped are up to 20 percent included Seattle and Tukwila mucks, and some are up to 5 percent the wet Bellingham soils. Permeability is very rapid. There is a water table at or close to the surface for several months each year. In areas where the water table is controlled, the effective rooting depth is 60 inches or more. In undrained areas, rooting depth is restricted. The available water capacity is high. Runoff is ponded, and there is no erosion hazard. 6.3 Soils Results The soil at sample location 1 (SL-1) is a hydric loamy muck. From 0 to 10 inches, the soil is a black (10YR 2/1) loamy muck. From 10 to 20 inches, the soil is a very dark grayish brown (10YR 3/2) clay loam. The soil is hydric because it has a one-chroma matrix immediately below the "A" horizon or at ten inches, whichever is shallower (Department of Ecology, 1997). The soil at SL-2 is a clayey muck. From 0 to 10 inches, the soil is a black (10YR2/1) loamy muck. From10 to 20 inches, the soil is a very dark grayish brown (10YR 3/2) clay loam. The soil is hydric because it has a one-chroma matrix below the "A" horizon or at ten inches, whichever is shallower (Department of Ecology, 1997). 5 Midway Samoan Assembly of God Church Property Wetland Study November 2019 Figure 2. Soil Map of Project Site (Websoil Survey, 2019, NOTE: Not Drawn to Scale). The soil at SL-3 is a gravelly sandy loam which is previously filled material. From 0 to 12 inches, the soil is a very dark grayish brown (10YR 3/2) gravelly sandy loam. From 12 to 20 inches, the soil is a very dark grayish brown (10YR 3/2) gravelly sandy loam. The soil is non-hydric because it has a two-chroma matrix, without mottles, below the "A" horizon or at ten inches, whichever is shallower (Department of Ecology, 1997). 7.0 Hydrology 7.1 Determination of Wetland Hydrology The Corps of Engineers Wetlands Delineation Manual (COE, 1987) and the Washington State Wetlands Identification and Delineation Manual (DOE, 1997) require inundation, flooding, or saturation to the surface for at least 5% of the growing season to satisfy the hydrology requirements for jurisdictional wetlands. Areas that are saturated between 5% and 12.5% of the growing season may or may not be wetlands. The growing season can either be defined by the number of frost -free days (temperatures above 280F), or the period during which the soil temperature, at a depth of 19.7 inches, is above biological zero (410F). Some factors that influence the amount of moisture or wetness in the site may include normal rainfall, climate, soil texture, drainage, plant cover, landscape/geomorphic settings, and stratigraphy. 6 � Midway Samoan Assembly of God Church Property Wetland Study November 2019 The presence of wetland hydrology at each sample location was determined using primary and/or secondary wetland hydrology indicators established by US Army Corps of Engineers. 2010. Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region Version 2.0 and the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). In addition to direct visual observation of inundation or saturation, secondary hydrologic indicators were used to infer wetland hydrology. Secondary indicators include oxidized channels (rhizospheres) associated with living roots and rhizomes, water marks on vegetation or fixed objects, drift lines, water -borne sediment deposits, water stained leaves, surface scoured areas, wetland drainage patterns, morphological plant adaptations, and hydric soil characteristics. 7.2 Hydrology Results Sample Location #1 has wetland hydrology. The sample location has wetland hydrology indicators showing water table at 23 inches from the surface and saturation is present at approximately 20 inches from the surface (see Data Form 1).. Sample Location #2 has wetland hydrology. The sample location has wetland hydrology indicator showing the water table present at a depth of approximately 17 inches from the surface and saturation at a depth of 12 inches from the surface (see Data Form 2). Sample Location #3 has no wetland hydrology. There are no wetland hydrology indicators observed at this sample location. There is no water table observed at 24 inches from the surface. The soil profile is dry. (see Data Form 3). The sources of wetland hydrology are precipitation, storm water, and surface runoff. 8.0 Wetland and Stream Determination, Ratings, and Buffers Wetland and stream category, ratings, and buffers were determined by referencing the Federal Way Municipal Code Chapter 19.145 - Environmentally Critical Areas and the Wetland Rating System for Western Washington, 2014 Version, . There is a wetland on the subject property. The wetland has a palustrine scrub -shrub (PSS), palustrine forested (PFO), and palustrine emergent (PEM) classes of vegetation (Cowardin, 1979). The hydrophytic plant community is dominated by Pacific willow, reed canary grass, creeping buttercup, Himalayan blackberry. The hydrogeomorphic classification is a Depressional wetland. Its sources of hydrology are seepage, precipitation, storm water discharge, and surface runoff. The soils are a hydric clayey muck with one-chroma matrix with water table at 17 to 23 inches from the surface. An off -site stream is mapped just to the east of the subject property and is separated from the subject parcel by a levee. The stream has seasonal water flowing particularly during the rainy months of the year. The stream and levee has been mowed regularly. 7 � Midway Samoan Assembly of God Church Property Wetland Study November 2019 There is no flowing water in the mapped stream but only some accumulation of run-off water from streets and residential areas from the east side of the stream. The remainder of the subject property is upland. The soil is a non-hydric, two-chroma matrix gravelly sandy loam, with no redox features in the soil profile. The water table is not present at 24 inches from the surface. A portion of the upland area is covered by lawn grasses previously planted. Based on the 2014 Version of the Washington State Wetland Rating System for Western Washington, and the Federal Way Municipal Code Chapter 19.145.420.C, the wetland is rated with a total function score of 19 points and is rated a Category III wetland (see Wetland Rating attached). The wetland has a Habitat Function Score of 4 points. According to the Federal Way Revised Code Chapter 19.145.420 (2), a Category III wetland with a Habitat function Score of 3 - 5 points, shall have a standard buffer width of 80 feet, measured from the wetland edge. (see attached wetland and stream sketch map). The off -site stream is classified in the DENR FPARS and King County GIS maps as a Type `F" waters Federal Way Revised Code 19.145.260.2.b, Type F stream are streams that contains fish habitat. According to the Federal Way Municipal Code Chapter 19.145.270.1.a - Stream Buffers Type F stream shall have a buffer width of 100 ft measured from the Ordinary High Water Mark (OHWM) (see wetland and stream buffer sketch map). 9.0 Impacts The study show that the remainder of the property including its existing building structures is within wetland buffer areas. The final impact assessment will be done when the approved critical areas designation and site development plans are prepared. Impacts to critical areas must be avoided in accordance to the provisions of the Federal Way Revised Code Chapter 19.145.440 — Development within the Wetland Buffer. 10.0 Authority This wetland/stream determination is in accordance with Section 404 of the Clean Water Act, the objective of which is to "maintain and restore the chemical, physical, and biological integrity of the waters of the United States" (DOE, 1997). Wetlands are "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (EPA, 40 CFR 230.3 and CE, 33 CFR 328.3)". 8 � Midway Samoan Assembly of God Church Property Wetland Study November 2019 11.0 Limitations Wetland and stream determinations are not final until approved by regulatory agencies and/or local jurisdictions.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? N0 go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressionat wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; _.At least 30% of the open water area is deeper than 6.6 ft (2 m). NO? go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). S. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number N0 go to 6 YES - The wetland class is Riverine OTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO -go to 7 YES The wetland class is Depressional 7. Is the entire wetland unit located in a very_flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. (N901Lgo to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Mature forests - Stands with average diameters exceeding 21 in (53 cm) dbh; crown cover may be less than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old -growth; 80-200 years old west of the Cascade crest. — Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 - see web link above). — Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. — Westside Prairies: Herbaceous, non -forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p. 161 - see web link above). Z Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. — Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report - see web link on previous page). — Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. — Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. -- Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. — Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to enable cavity excavation/use by wildlife.
