Critical Area Study 1181h Avenue SE Wetland and Stream Report I. Introduction EDA W Inc. was commissioned by Rolluda Architects, Inc. to delineate all wetlands, streams and relevant biological critical areas located in the vicinity of a subject parcel (Parcel #619660 0440) located at 7644 118 1 h Avenue SE in Renton (Figure 1). Parcel residents reported a potential wetland area existing in the southeastern portion of the property that maintained persistent areas of open water (Photo I). This study was conducted to confirm the presence of this and any other potential biological critical areas existing in the vicinity of the subject parcel and to provide a classification for potential wetlands and streams in accordance with King County Code (KCC) Chapter 21 A.24. As part of comprehensive critical areas review for the King County Department of Development and Environmental Services (DDES), field studies conducted as part of this delineation report also included reconnaissance-level review to determine if project site habitat potentially meets criteria for biological critical areas as defined in KCC Chapter 2 lA.24 including aquatic areas, wildlife habitat conservation areas, and wildlife habitat networks. Critical areas identified in this report are classified according to KCC 21 A.24 with specific mandates for protective buffer widths designated per KCC 21A.24.325 (wetlands) and 21A.24.358 (streams). ,, An initial reconnaissance of the subject property was conducted to begin field studies on April 21, 2005. This initial property reconnaissance resulted in the identification of a potential wetland area extending across the southern property boundary and a consolidated surface channel leading to the wetland area from the north potentially meeting criteria for a jurisdictional stream. These potential biological critical areas were labeled and initially identified as described below: Photo I. Area identified as Wetland A defined • Wetland A. Wetland A was identified through observation of evident wetland hydrology which included areas of open water up to approximately two feet in depth. The open water area was noted to support an array of peripheral emergent wetland vegetation dominated by slough sedge (Carex obnupta). Wetland hydrology was by evident standing water. All areas shown exist off-site. April 2005 noted to be relatively contained, with little extension of evident hydrology, hydric soils, and/or hydrophytic vegetation far beyond the periphery of open water areas, due to topographic constraints. The potential wetland area is located at the base of a large swale, with relatively steep forested slopes to the west and east and a gentle rise to the north, along the southern C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Rol/uda Wetland\Rolluda Wetland and Stream Report.doc K.C. Critical Area Study 118'" Avenue SE Wetland and Stream Report portion of the property approximately 90 feet west of the eastern property boundary (Figure 2). Wetland hydrology appears to be largely maintained through surface flow (no seeps were noted along the adjacent slopes) conveyed from the surrounding slopes and the consolidated surface channel entering the wetland from the north (described below). • Stream Channel. The stream channel flowing from the north to Wetland A was identified topographically by large evident channel edges. Though distinct flow was not noted during field studies, portions of the stream channel contained shallow standing water and evidence of gravel/sediment sorting provided an indication of historical water movement. The property owner reported that residents to the north had graded adjacent areas (including a portion of the subject parcel) to improve drainage. The stream channel now appears to begin at the downhill side of a mowed lawn (Photo 2) and conveys flow to a channel that has likely been enhanced (widened and deepened) through excavation. Subsequent technical field studies were conducted as described below to provide a formal delineation and boundary determination for these potential jurisdictional areas identified as part of initial site reconnaissance. For the purposes of federal, Washington State, and King County jurisdictional oversight, methodology used for wetland delineation is consistent with the wetland definition provided in paragraph 25a of the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology [WDOE] 1997). The wetland criteria in the WDOE manual is consistent with the 1987 manual required for use by the U.S. Army Corps of Engineers (Corps 1987). The following sections provide: (I) an introduction to the site; (2) a description of methods used in field delineation; and, (3) technical results. Photo 2. Uphill beginning of stream channel.

Critical Area Study 1181 ' Avenue SE Wetland and Stream Report II. Site Description The project site is located in rural unincorporated King County east of the City of Renton in Section 33, Township 23N, Range 5E (Figure I). The parcel includes 2.047 acres extending from I 18th Avenue SE east to a utility corridor (transmission lines) running north-south off the eastern property boundary. The property address, 17644 l l 81h Avenue SE, places it outside of the incorporated City of Renton, but within the King County Urban Growth Area (UGA) boundary. Historically, development on the subject property has been limited to the western half of the parcel. Currently, an occupied residence and at least three outbuildings in various states of disrepair exist on the parcel (Figure 2). Although the eastern portion of the parcel exists as relatively undisturbed mixed deciduous-coniferous forest, residual non-native invasive plant species including Himalayan and evergreen blackberry (Rubus discolor and R. laciniatus), giant knotweed (Polygonum sachalinense), Herb Robert (Geranium robertianum), laurel (Laurus sp.), holly (llex sp. ), and English ivy (Hedera helix) have become extensively established along the western edge of the forested area adjacent to abandoned developed areas. In areas east of the influence of historical development, vegetation communities and habitat are typical of deciduous-coniferous forests of the Pacific Northwest. This upland forest is characterized by a tree canopy of Douglas fir (Pseudotsuga menzicsii), western hemlock (Tsuga heterophylla ), big- leaf maple (Acer maerophyllum) and red alder (A/nus rubra), and an understory of vine maple (Acer circinatum), Indian plum (Oemleria cerasiformis ), salal (Gaultheria shallon) and sword fem (Polystichum munitum). See Table I for a list of plant species noted in the on-site upland and wetland areas. Data on critical areas existing at the project site are largely inconsistent. King County iMAP critical areas (previously sensitive areas) data show a Class 2 (previous system of classification) stream transecting the northeastern comer of the subject parcel. However, this information is inconsistent with iMAP 2002 aerial photographs which show no evident stream channel in the location demarcated by the G!S data. In addition, stream flow as depicted by King County GIS data is inconsistent with surveyed site topography and would require flow to be conveyed uphill across a topographic rise located in the southeastern portion of the parcel. It is likely that the GIS data has been erroneously offset to the east, with the data indicating a potential stream channel extended to the north without regard for actual features, site topography or confirmed ground- truthing. In actuality, the subject parcel is transected by a broad topographic valley with a rise of approximately 40 feet from the low point along the wetland and inflowing stream channel to 1181h Avenue to the west; and a rise of approximately 10 feet to the property boundary on the east (Figure 2). Surface water is conveyed from vicinity slopes to the floor of this diverse swale and then southward to the area defined as Wetland A. A distinct stream channel -with evidence of sediment sorting, manifest water flow, defined edges, and a demarcated ordinary high water (OHW) mark -is evident extending approximately 100 feet from the northern edge of Wetland A. To the north of the subject parcel in the vicinity of the stream channel the area has been historically graded to accommodate development, and an existing maintained lawn extends April 2005 3 C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Rolluda Wetland\Rolluda Wetland and Stream Report.doc K.C.

Critical Area Study 118th Avenue SE Wetland and Stream Report across the parcel boundary from the north to the beginning of the defined stream channel. As mentioned above, it is likely that this stream channel has been excavated to facilitate water movement and, over its short length ( especially at the wetland outfall), the stream channel now appears "oversized" given likely flows. A review of regional King County iMAP critical areas data shows that flows from the on-site stream are conveyed through the area defined as Wetland A and continue southeast to eventually flow into a riparian/wetland complex associated with the upper reaches of Big Soos Creek. Preliminary reconnaissance in the vicinity of the subject parcel identified an 18-inch culvert leading from the southeast comer of the potential wetland area (at the outfall located off-site, to the southeast in the utility corridor parcel) under the transmission line corridor located east of the subject parcel to a large Spirea-dominated scrub-shrub wetland associated with Big Soos Creek. This large wetland complex is located approximately 800 feet east of the subject parcel and is identified on King County GIS data as a Class 1 \Vetland (previous King County sensitive areas designation). In addition to this large off-site wetland complex, King County GIS data indicates a smaller Class 4 wetland located approximately 700 feet to the southeast of the subject parcel. Preliminary site reconnaissance did not include study of the flow path beyond the 18-inch outfall culvert off of Wetland A. Given the uncertainty in King County critical areas GIS data pertaining to this area, it is unclear if on-site flows are conveyed to the large Class 1 wetland complex to the east, or the smaller Class 4 wetland to the southeast. Forested areas in the eastern portion of the subject property provide suitable habitat for a wide variety of wildlife species. High quality native forest habitat is especially prevalent in the eastern portion of the parcel where significant densities of non-native invasive plant species have yet to establish. Numerous passerine species were detected during delineation field studies including black capped chickadee (Poecile atricapilus), bushtit (Psaltriparus minimus), Wilson's warbler (Wilsonia pusilla), American robin (Turdus migratorius) and Stellar's jay (Cyanocitta stelleri). In addition, lotic habitat associated with the wetland and stream channel provides suitable habitat for common amphibian species including the chorus frog (Hy/a regilla), red-legged frog (Rana aurora) and Northwestern salamander (Ambystoma gracile).

Methods A. Wetland & Stream Authority, Definition, and Classification Methodology used for wetland delineation is consistent with the Washington State Wetlands Identification and Delineation Manual (WDOE 1997 [1997 Manual]). This document is the wetland delineation manual that is used in determining wetland areas when applying state and local government regulations under the Shoreline Management Act (SMA) and the Growth Management Act (GMA) in Washington State. The 1997 Manual is a revised version of the U.S. Army Corps of Engineers Wetlands Delineation Manual (Corps 1987) and incorporates the key provisions of various guidance letters and memoranda: U.S. Army Corps ofEngincers (Corps) Regulatory Guidance Letters 82-2, 86-9, and 90-7; Corps 3-92 Memorandum; Corps, Seattle District, 5-94 Public Notice; DOE, 3/95 Public Notice; United States Department of Agriculture, Natural Resource Conservation Service, 6/95 Guidance Letter. The King County Critical Areas Ordinance grants King County the responsibility and authority to regulate environmentally critical areas, including wetlands and streams, within its local jurisdiction. Wetland classification within King County is based upon ratings found in Section 21A.24.318 of King County Code (KCC) as follows: 21A.24.318 Wetlands -categories. A Wetlands are classified into category I, category II, category Ill and category IV based on the adopted Washington State Wetland Rating System for Western Washington, Washington state department of ecology publication number 04-06-025, published August 2004. B. Wetland rating categories shall not recognize illegal modifications. (Ord. 15051 § 183, 2004). The Washington State Wetland Rating System for Western Washington (Hruby 2004) largely bases wetland classification upon the scoring on a Wetland Rating Form assessing wetland functioning in regard to water quality, hydrology and provision of wildlife habitat. In general, scores on the wetland rating form provided in Hruby 2004 correspond to wetland category as follows: • Category I Wetlands -cc 70 points; • Category II Wetlands -51-69 points; • Category III Wetlands -30-50 points; and • Category N Wetlands -<30 points. Wetland rating forms from Hruby 2004 used in the classification of wetlands existing in the vicinity of the subject parcel are provided as an attachment to this report (see Appendix 2). Stream classification and water typing within King County are based upon Section 21A.24.355 9fK.ing County Code (KCC) as follows: April 2005 7 C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Rol/uda Wetland\Rolluda Wetland and Stream Report.doc K.C. Critical Area Study 118'" Avenue SE Wetland and Stream Report 21A.24.355 Aquatic areas -water types. A. Aquatic areas are categorized or "typed" as follows: 1. Type S waters include all aquatic areas inventoried as "shorelines of the state" under King County's Shoreline Master Program, K.C.C. Title 25, in accordance with chapter 90.58 RCW, including segments of streams where the mean annual flow is more than twenty cubic feet per second, marine shorelines and lakes twenty acres in size or greater; 2. Type F waters include all segments of aquatic areas that are not type S waters and that contain fish or fish habitat, including waters diverted for use by a federal, state or tribal fish hatchery from the point of diversion for one-thousand-five-hundred feet or the entire tributary if the tributary is highly significant for protection of downstream water quality; 3. Type N waters include all segments of aquatic areas that are not type Sor F waters and that are physically connected to type S or F waters by an above-ground channel system, stream or wetland; and 4. Type O waters include all segments of aquatic areas that are not type S, F or N waters and that are not physically connected to type S, For N waters by an above- ground channel system, stream or wetland. B. For the purposes of the water types in subsection A. of this section, an above- ground channel system is considered to be present if the one-hundred year floodplains of both the contributing and receiving waters are connected. C. The department may determine that an area upstream of a legal human-made barrier is not fish habitat considering the following factors: 1. The human-made barrier is located beneath public infrastructure that is unlikely to be replaced and it is not feasible to remove the barrier without removing the public infrastructure; 2. The human-made barrier is in the Urban Growth Area established by the King County Comprehensive Plan and is located beneath one or more dwelling units and it is not feasible to remove the barrier without removing the dwelling unit; 3. The human-made barrier is located in a subbasin that is not designated "high" on the Basin and Shoreline Conditions Map which is included as Attachment A to this ordinance; or 4. The human-made barrier is not identified for removal by a public agency or in an adopted watershed plan. (Ord. 15051 § 192, 2004). This water typing system is based upon the Washington State Department of Natural Resources permanent water typing system as mandated for State use in Washington Administrative Code (WAC) 222-16-030. B. Review of Existing Information Consistent with procedures detailed in the 1997 Manual, the EDAW, Inc. team gathered preliminary information on the project site prior to field review and delineation. General information sources include: • • • • • Soil Survey of the King County Area, Washington (USDA 1973); Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al. 1979); List of Plant Species that Occur in Wetlands: Northwest (Region 9) (Reed 1988); King County Critical Areas Ordinance (KCC Chapter 21A.24); and National Wetlands Inventory .

Field Delineation The extent and location of project site wetlands and streams were determined during field work performed on April 21, 2005. Field work was conducted under overcast skies with occasional light precipitation and an ambient temperature of approximately 55 degrees Fahrenheit. Recent local weather had generally included days with periods of light rain and sun breaks and the history of recent weather and precipitation was considered in assessing the type and extent of wetlands presumed to exist on site. Wetlands identified during field work are considered potential wetlands until their presence is confirmed through King County Department of Development and Environmental Services or U.S. Army Corps of Engineers review. Specific field methodology used in determining the extent and location of wetland areas include: • As part of the initial project site reconnaissance, the site was walked to determine the general extent and location of potential wetland areas (reconnaissance); • Potential wetland areas were inspected for hydrological links, adjacent areas were re- assessed for potential wetland indicators; • Wetland sample plots were established in potential wetland areas and, as necessary, in adjacent uplands; and • Wetland boundaries were delineated with flagging by noting localized topography and vegetation patterns and comparing parameters of hydrology, soil, and vegetation with data collected at wetland and upland sample plots. 1. Plot Sampling A wetland sample plot was established in the vicinity of potential Wetland A. The sample plot was located to avoid areas with obvious inundation and to test potential wetland parameters along the periphery, at the potential wetland-upland boundary. Data collected in the wetland sample plot were compared with data collected from an on-site upland sample plot. The locations of sample plots are indicated in Figure 3. These sampling locations, marked in the field with pink labeled flagging, were used as sites for the collection ofhydrologic, soil, and vegetative data in accordance with the methodologies set forth in the 1997 Manual. Data collected at each sample plot were entered onto a Routine Wetland Determination Data Form (WDOE 1997). Copies of data forms for each sample plot are appended to this delineation report (Appendix 3). a. Hydrology Evaluation According to the 1997 Manual, wetland hydrology is present in areas that are inundated and/or saturated to the surface for a consecutive number of days greater than 12.5 percent of the growing season (approximately 2 weeks in Western Washington). Saturation to the surface is assumed when the water table -the level at which standing water is found in an unlined hole -is found April 2005 9 C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Ro//uda Wetfand\Rolluda Wetland and Stream Report.doc K.C. Critical Area Study 118th Avenue SE Wetland and Stream Report within 12 inches of the surface in a non-sandy soil or within 6 inches of the soil surface in sandy soils. To evaluate hydrology, a small soil test pit was excavated to a depth of 16 inches at the center of each sample plot. The extent of soil inundation and saturation as well as the depth to free water in the test pit were recorded on the Routine Wetland Determination Data Forms as an indication of potential wetland hydrology. Other recorded potential field indicators of wetland hydrology, as listed in the 1997 Manual, include oxidized channels (rhizospheres) associated with living roots, water marks on vegetation or fixed objects, drift lines, sediment deposition on vegetation and other objects, water-stained leaves, wetland drainage patterns, and hydric soil characteristics (see appended Routine Wetland Determination Data Forms). b. Soil Evaluation The presence ofhydric soils was determined consistent with the 1997 Manual, and current regulatory guidance (Corps 3-92 Memorandum; United States Department of Agriculture, Natural Resources Conservation Service, 6/95 Guidance Letter). The definition of a hydric soil is " ... a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part" (USDA, NRCS 1996). Fulfillment of the technical criteria for soil can be inferred by using a combination of published soils information and field indicators. The indicators available for determining whether a soil satisfies the basic definition and the technical criteria for hydric soils include, but are not limited to the following: • The soil is a histosol • A histic epipedon is present • Hydrogen sulfide odor is present • The soil is gleyed • The soil occurs in an aquic or peraquic moisture regime • The soil exhibits reducing conditions • The soil has a low chroma matrix with redoximorphic features (e.g., mottles) • Iron and/or manganese concretions are present • The soil appears on the hydric soils list A soil profile to a depth of 16 inches was extracted from each sample plot test pit and the depth and character of each distinct soil horizon was recorded. A Munsell soil color chart (Munsell Color 1988) was used to characterize the soil. In accordance with the 1997 Manual field protocol, soil color, hue, and chroma were recorded for each soil profile immediately below the "A" horizon or at a depth of IO inches, whichever is shallower. All information collected on field soil profiles was recorded on the Routine Wetland Determination Data Form for each sample plot. c. Vegetation Evaluation At each sample plot, vegetation was characterized by determining the percent aerial cover of each April 2005 10 C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Rolluda Wetland\Rolluda Wetland and Stream Report.doc K.C. Critical Area Study 11 B'h Avenue SE Wetland and Stream Report plant species occurring within the herb, shrnb, and tree stratum. Dominant species in each of the three strata (tree, sapling/shrnb, and herb) were identified and recorded on the Routine Wetland Determination Data Form for each sample plot. Percent cover for trees, defined as any woody plant species with a diameter at breast height (dbh) of 2: 3 inches, was estimated in a 30-foot radius from the center of the sample plot; shrubs, defined as any woody plant with a height of> 3.2 feet and a stem diameter of< 3 inches, was estimated in a IO-foot radius from the sample plot pin flag; and herbaceous plant species, defined as vegetation< 3.2 feet in height, was estimated in a 3.2-feet square quadrat located around the sample plot soil pit. Dominant species are those species in each stratum that, when ranked in descending order of abundance and cumulatively totaled, immediately exceed 50 percent cover of the total dominance measure for that stratum, plus any species that comprise at least 20 percent cover. The wetland indicator status of the dominant species within each vegetation stratum was used to determine the presence ofhydrophytic wetland vegetation. Each species' indicator status is defined according to Reed (1988). A species indicator status refers to the relative frequency with which the species occurs in jurisdictional wetlands (Table 3 ). According to the 1997 Manual, an area meets the hydrophytic vegetation criteria when, under normal circumstances, more than 50 percent of the dominant species from each stratum are obligate wetland (OBL), facultative wetland (FACW), and/or facultative (FAC) species. For the purposes of 1997 Manual protocol, a plus ( +) or a minus (-) sign is often included in the designation to specify a higher or lower (i.e., wetter or dryer) indicator status, and a FAC- indicator status is not considered to be an indicator ofhydrophytic vegetation (i.e., it is treated in Table 3. U.S. Fish & Wildlife Service olant indicator status. Indicator Status Definition Obligate Wetland (OBL) Occur almost always ( estimated probability >99%) under natural conditions in wetlands.

Critical Area Study 118th Avenue SE Wetland and Stream Report allows for the presence of facultative upland (FACU) dominated plant communities where the presence of wetland hydrology is clearly identified (Corps, Seattle District, 5-94 Public Notice). 2. Boundary Delineation After characteristics of hydrology, soil, and vegetation were compared between the confirmed upland and wetland sample plot, a boundary determination was made in the field. The wetland boundary was determined by first noting likely areas of topographic and vegetative distinction between wetlands and uplands, and then using soil borings to determine the boundary between hydric and non-hydric soils. The wetland boundary was marked with flagging spaced at a distance of approximately IO to 20 feet depending upon wetland size and site features. April 2005 12 C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Rolluda Wetland\Rol/uda Wetland and Stream Report.doc K.C. Critical Area Study 118th Avenue SE Wetland and Stream Report IV. Results As indicated above, initial site reconnaissance identified a potential wetland area, Wetland A, and a potential jurisdictional stream at the project site. The potential wetland area was identified based on the presence of wetland vegetation and hydrology -specifically, a large contiguous area of surface ponding -that suggested inundation and/or saturation to the surface for a likely period of over 12.5 percent of the growing season. This area was detennined to be a jurisdictional wetland in accordance with the specific findings on wetland hydrology, soils, and vegetation provided below. The boundary of Wetland A was delineated only in those portions that exist on the subject parcel. Wetland A extends off of the subject parcel to the south, but access to adjacent lots precluded delineation of the majority of Wetland A (see below). A. WetlandA Fignre 3 shows the location of Wetland A and the placement of the associated wetland test pit relative to specific site features. 1. Hydrology The test pit excavated within the wetland revealed that wetland hydrology criteria were met, most notably by observation of soil saturation and standing water in the test pit. The test pit for Wetland A was located along the periphery of evident standing water. However, soil in the vicinity of the test pit was noted to be saturated to the surface, and water was easily extracted from soil surface layers with slight compression. Although the wetland test pit was located outside of evident standing water, subsurface water rapidly accumulated in the test pit following excavation. Upon excavation, standing water inundated the test pit to within 0.5 inch of the surface, indicating complete soil saturation along the immediate periphery of wetland ponding. 2. Soils Soils inspected in and around the wetland test pit are best classified as Mukilteo muck (USDA 1983). This very deep, very poorly drained soil is often found in small depressional areas and forms from organic material -often times from decomposing wetland sedges and other plant species. This wetland muck lacks distinct soil horizons in the soil profile to 16 inches depth. The soil profile exhibited a low matrix chroma (Munsell reading 1 OYR/2/1 at IO inches depth), consistent with that described in the King County soil survey for Mukilteo muck. Muckilteo muck is included on the hydric soils list for the King County area (USDA 1973). The dark color and clay component of the muck was noted to extend approximately I foot outside of the standing water in the wetland, and generally dissipate to an upland Alderwood series soil as topography around the wetland began to rise away from the evident ponding. 3. Vegetation The vegetation in Wetland A is distinguished from the surrounding forested areas by an increased April 2005 13 C:\Documents and Settings\KIRK-WORK MASTER\Project-Work\Ro//uda Wetland\Rol/uda Wetland and Stream Report.doc K.C. Critical Area Study 11 s'h Avenue SE Wetland and Stream Report density ofhydrophytic plant species. This distinction between plant communities is quite pronounced and generally follows site topography along the periphery of wetland ponding. On the subject parcel, the wetland boundary generally follows a pronounced rise in elevation of approximately one foot. On the upland side of the boundary, the forest plant community is characterized by a dense shrub layer dominated by salal ( Gaultheria shallon) and sword fem (Polystichum munitum). On the wetland side of the boundary, obligate species-most notably dense stands of slough sedge (Carex obnupta)-are established. Table 4 below provides a list of plants species detected during vegetation analysis in the sample plot for Wetland A. Table 4. Plants ecies identified as art of Wetland Ave elation anal sis. Scientific Name *Shading indicates dominant plants within wetland sample plot. **Percent cover estimates from vegetation in wetland sample plot. Indicator Status Percent Cover** 4% 3% 2% As indicated (Figure 3), the sample plot for Wetland A is located along the periphery of the wetland on the subject parcel. In this area, the wetland plant community is fairly homogenous and even monotypic -predominantly defined by high densities of emergents (slough sedge) along the water's edge. However, off-site, in the adjacent parcel to the south, the wetland plant community becomes more diverse and includes wetland shrub species such as Spirea (Spirea douglasii), twinberry (Lonicera involucrata) and red-osier dogwood (Cornus stolonifera), as well as additional obligate wetland species such as skunk cabbage (Lysichiton americanum) and small-fruited bulrush (Scirpus microcarpus) 4. Boundary Determination and Classification On April 21, 2005, the boundary of Wetland A existing on the subject property was delineated in the field with pink flagging labeled WA-1 through WA-12 (Figure 3). Following field delineation, surveyors recorded the position of wetland flagging.

This score provides a definitive classification for Wetland A according to KCC 21A.24.325 as a Category II wetland. Photo 3. Portion of Wetland A existing on site showing inflowing stream outfall. C. Area Uplands According to the Soil Survey of the King County Area (USDA 1973), upland soil in the vicinity of the project site is characterized as Alderwood gravelly sandy loam. This soil type was evident on the subject parcel outside of delineated wetland boundaries. This soil type was distinguished from the hydric muck evident in the wetland area by the presence of a sandy, at times, gravelly component to the surface soil, and the existence of distinct soil horizons. Soil in the uplands of the project site was noted to be reddish in color in the A horizon with chromas of 2 and above. The upland sample plot is located approximately 20 feet from the delineated wetland boundary. However, no water was observed in the upland test pit excavated to a depth of 16 inches. Soil was not noted to be saturated (even with occasional light precipitation occurring during field studies) and there was no evidence of recent or historical wetland hydrology in the vicinity of the upland sample plot. Table 5 below provides a list of plants species detected during vegetation analysis conducted in the upland sample plot. As noted, fewer than 50% of identified dominant plant species were found to have a wetland indicator status of F AC or wetter. Table 5. Plant species identified as Dart of upland veaetation analysis.

Streams As described above, a defined stream channel leads from the north-central portion of the subject property to the northern boundary of Wetland A (Figure 3). Although there is evidence that this stream channel has been expanded through excavation, it is likely that a smaller natural channel existed in the vicinity prior to disturbance. During field studies conducted on April 21, 2005, water was not noted to be flowing through the length of the defined channel (117 feet) which averages approximately 2.5 feet in width. However, shallow standing water (approximately 2 inches depth) was observed in portions of the channel. No fish species of any type were observed in the small stream channel transecting Wetland A and this small chanrn,.1-+foes not provide suitable habitat for any native or non-native Northwest fishery. Consistrn with KCC 21A.24.355 this stream channel is best classified as a Type N water. Although the stream channel provides no fish habitat in the vicinity of the subject parcel, this classification is justified as the stream is connected through surface channels to tributaries of Big Soos Creek (see Appendix I). Big Soos Creek itself drains to the Green River east of Auburn. Chinook salmon (Oncorhynchus tshawytscha), coho salmon (0. Kisutch), steelhead (0. mykiss), and cutthroat trout (0. clarki) are believed to migrate into the upstream reaches of Big Soos Creek (Kerwin and Nelson 2000), but impassible fish barriers (notably the 18 inch culvert at the downstream end of Wetland A) preclude fish access to stream reaches in the vicinity of the subject parcel.

Critical Area Study 1181h Avenue SE Wetland and Stream Report V. Conclusions Biological critical areas delineated at the project site as part of this study include: • Wetland A-a forested wetland meeting King County criteria for a Category II wetland with 2080 square feet existing at the project site as indicated in Figure 3; and, • Stream-a I I 7-foot long stream channel, with an average width of2.5 feet, meeting KC criteria for a Type N water. No other biological critical areas were identi tied on the site through field or data review as part of this study. A. Protective Buffers The subject parcel is currently zoned R6-SO (residential, 6 units per acre, special overlay) and is located within a KC VGA. The new CAO for King County bases protective buffer widths for biological critical areas on the degree of impact associated with adjacent land use. Subdivision (or short platting) of the subject parcel and residential development, with associated development of rights-of-way or access easements and utility systems, would constitute a "high impact" development per KCC 2 I A.24.325(B)(2). Protective buffer widths for wetlands adjacent to "high impact" land uses within the VGA boundary as mandated per KCC 21A.24.325(A)(l) are I 00 feet (this is also based upon the habitat score on the Wetland Rating Form; see Appendix 2). The protective buffer width for Wetland A on the subject parcel is established at I 00 feet from the delineated wetland boundary (Figure 3) According to KCC 21A.24.358, the protective buffer width for Type N streams located within the VGA boundary is 65 feet. Stream buffers are measured from the ordinary high water mark along either side of the stream channel (Figure 3). In addition to the required protective buffer widths for the biological critical areas delineated herein, King County Code requires maintenance of a 15 foot setback in which most development (excluding overhangs, decks and some impervious surfacing) must be excluded.

May be associated with cliffs. __ Caves: A naturally occurring cavity, recess, void, or system of interconnected passages __ Oregon white Oak: Woodlands Stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%. __ Urban Natural Open Space: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; and/or the open space is an isolated remnant of natural habitat larger than 4 ha (1,0 acres) and is surrounded by urban development. __ Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5% during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape ( e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function ( e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

YES= Go to SC I.I NO SC 1.1 Is the wetland within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332-30-151? YES = Cate o I NO o to SC 1.2 SC 1.2 Is the wetland at least I acre in size and meets at least two of the following three conditions? YES = Category I NO= Category II -The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less than 10% cover of non-native plant species. If the non-native Spartina spp. are the only species that cover more than I 0% of the wetland, then the wetland should be given a dual rating (I/II). The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category I. Do not, however, exclude the area of Spartina in determining the size threshold of I acre. -At least % of the landward edge of the wetland has a I 00 ft buffer of shrub, forest, or nu-grazed or un-mowed grassland. -The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands.

SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a Natural Heritage wetland? (this question is used to screen out most sites before you need to contact WNHPIDNR) SIT/R information from Appendix D _ or accessed from WNHP/DNR web site _ YES __ -contact WNHP/DNR (seep. 79) and go to SC 3.2 NO SC 2.2 Has DNR identified the wetland as a high quality undisturbed wetland or as or as a site with state threatened or endangered plant species? YES = Category I NO SC 3.0 Bogs (seep. 87) Does the wetland ( or part of the wetland) meet both the criteria for soils and vegetation in bogs? Use the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the wetland based on its functions. 1. Does the wetland have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that compose 16 inches or more of the first 32 inches of the soil profile? (See Appendix B for a field key to identify organic soils)? Yes -go to Q. 3 No -go to Q. 2 2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or pond? Yes -go to Q. 3 No -Is not a bog for purpose of rating 3. Does the wetland have more than 70% cover of mosses at ground level, AND other plants, if present, consist of the "bog" species listed in Table 3 as a significant component of the vegetation (more than 30% of the total shrub and herbaceous cover consists of species in Table 3)? Yes-Is a bog for purpose of rating No -go to Q. 4 NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16" deep. If the pH is less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog. 3. Is the wetland forested (> 30% cover) with sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine, quaking aspen, Englemann's spruce, or western white pine, WITH any of the species (or combination of species) on the bog species plant list in Table 3 as a significant component of the ground cover (> 30% coverage of the total shrub/herbaceous cover)? 4.

SC 4.0 Forested Wetlands (seep. 90) Does the wetland have at least 1 acre of forest that meet one of these criteria for the Department of Fish and Wildlife's forests as priority habitats? Jfyou answer yes you will still need to rate the wetland based on its functions. -Old-growth forests: (west of Cascade crest) Stands of at least two tree species, forming a multi-layered canopy with occasional small openings; with at least 8 trees/acre (20 trees/hectare) that are at least 200 years of age OR have a diameter at breast height (dbh) of 32 inches (81 cm) or more. NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW criterion is and "OR" so old-growth forests do not necessarily have to have trees of this diameter. -Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 -200 years old OR have average diameters ( dbh) exceeding 21 inches (53cm); crown cover may be less that 100%; decay, decadence, numbers of snags, and quantity oflarge downed material is generally less than that found in old-growth. YES = Category I NO SC 5.0 Wetlands in Coastal Lagoons (seep. 91) Does the wetland meet all of the following criteria of a wetland in a coastal lagoon? -The wetland lies in a depression adjacent to marine waters that is wholly or partially separated from marine waters by sandbanks, gravel banks, shingle, or, less frequently, rocks -The lagoon in which the wetland is located contains surface water that is saline or brackish(> 0.5 ppt) during most of the year in at least a portion of the lagoon (needs to be measured near the bottom) YES = Go to SC 5.1 NO_ not a wetland in a coastal lagoon SC 5.1 Does the wetland meets all of the following three conditions? -The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing), and has less than 20% cover of invasive plant species ( see list of invasive species on p. 7 4). -At least % of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un-mowed grassland. -The wetland is larger than 1/10 acre ( 4350 square feet) YES = Category I NO = Category II Wetland Rating Form -western Washington 20 August 2004 Cat.

YES -go to SC 6.1 NO ~ not an interdunal wetland for rating If you answer yes you will still need to rate the wetland based on its functions. In practical terms that means the following geographic areas: • Long Beach Peninsula-lands west of SR 103 • Grayland-Westport-lands west of SR 105 • Ocean Shores-Copalis-lands west of SR 115 and SR I 09 SC 6.1 Is the wetland one acre or larger, or is it in a mosaic of wetlands that is once acre or larger?

The existing house, accessory dwelling and sheds on Lots 2-5 will be removed in order to construct new single family dwelling on each lot. The proposed density is 5.6 dwellings per acre (6 units X 1.08 net acres). The most recent short plat revision was received January 10, 2008. The lot count was reduced from 7 down to 6 lots, the recreation tract and critical areas tract were revised, and a future cul-de- sac was added fronting lots 3 and 4 on proposed SE. 1761h Pl.

Effective March 1, 2008, the City approved an ordinance to accept the annexation area and all local governmental land use authority and jurisdiction with respect to the Annexation Area transferred from the County to the City upon the effective date. The City and the County approved execution of an lnterlocal Agreement relating to the Annexation Area for the purpose of in part establishing the process and authority for discretionary decisions with respect to land use and permitting from and after the date of annexation. Therefore under the provisions of Section 2.3 of the agreement, the County has prepared this report and recommendation to the City's designated decision-maker for a final decision. The City is responsible for scheduling, providing notice, conducting any appeals hearing and making any final decision this application. County staff will attend an appeals hearing to testify with respect to analysis set forth in the County's report and recommendation if the application is appealed. D. NATURAL ENVIRONMENT 1. Topography: The property slopes from elevation 450, west down to the east 1/3 where there is a broad swale at elevation 406, then the property rises to 416 at the northeast corner. 2. Soils: The following soils are found on this site per King County Soil Survey: AgB -Alderwood gravely, sandy loam; 0-6% slopes. Runoff is slow and the erosion hazard is slight. This soil type has a moderate limitation for low building foundations due to a seasonally high water table and severe limitations for septic tank filter fields due to very slow permeability in the substratum. Age -Alderwood gravely, sandy loam; 6-15% slopes. Runoff is slow to medium and the hazard of erosion is moderate. This soil has a moderate limitation for foundations, due to a seasonally high water table and slope. It has a severe limitation for septic tank filter fields due to very slow permeability in the substratum. 3. Wetland/streams: According to the King County Sensitive Areas Folio, both a wetland and stream are present on the far end of the site. A wetland and stream report was prepared by EDAW dated 4/2005, then a subsequent report was prepared by AlderNW, dated 3/26/2007 and later on 10/30/2007 AlderNW provided a further updated report. The report indicates that there is a wetland on the east 1/3 approximately 4,200 square feet extending beyond property boundaries both north and south of the site and the seasonal stream is also within this corridor. The wetland buffer required is greater than the stream buffer and therefore the wetland buffer is controlling. With enhancement to the wetland, the 100' wide wetland buffer may be reduced to 75'. 4. Vegetation: This site is primarily covered in grass and ornamental shrubbery on the west half and the east half is wooded in a natural state. The short plat topography survey plan dated 6/13/06 identifies the location and size of significant trees and smaller trees on site. 5. Wildlife: Small birds and animals likely visit this site; however, their population and species are limited due to nearby development. No threatened or endangered species are known to exist on or near the property. 6. Mapped Critical Areas: The Sensitive Areas Folio identifies that there is a wetland and stream on this site. E. DESIGN FEATURES 1. Density, Lot Pattern, Comprehensive & Community Plan: The density for this proposal will yield 5.6 dwelling units per acre. The net density calculation excludes the wetland area and recreation/drainage area of the site. The lots as proposed include the square footage as follows: Lot 1 Lot 2 Lot 3 3,839 square feet 4,071 square feet 4,173 square feet Lot 4 Lot 5 Lot 6 6,340 square feet 6, 350 square feet 7,050 square feet Lots range from 40 feet in width to 50 feet in width. The property is in the Soos Creek Community Planning Area. The immediate surrounding neighborhood is in transition from a low density rural area to an urbanized area with medium density residential development.

Access/Roadway: The six lot short plat is located on the east side of 118th Ave. SE, an urban neighborhood collector, which is currently improved with a rural shoulder-type section. The proposal is to upgrade the frontage with curbs and sidewalks. The proposed on-site access road (SE 176th Pl.) will be improved as an urban minor access street (less than 150 feet long without a cul-de-sac). The road alignment is necessary to provide a possible connection to the neighboring property to the south. 3. Traffic Generation: It is expected that approximately 50 additional vehicle trips per day will be generated with development of five additional homes. The calculations include service vehicles (i.e., mail delivery, garbage pick-up, school bus) which may currently serve this neighborhood, as well as work trips, shopping, etc. With the existing home 10 vehicle trips are calculated as currently using local roads. 4. Adequacy of Arterial Roads: This proposal has been reviewed under the criteria in King County Code 14.70, Transportation Concurrency Management; 14.80, Intersection Standards; and King County Code 14. 75; Mitigation Payment System. a. King County Code 14.70 -Transportation Concurrency Management: The Transportation Certificate of Concurrency dated January 10, 2006, indicates that transportation improvements or strategies will be in place at the time of development, or that a financial commitment is in place to complete the improvements or strategies within six (6) years, according to RCW 36. 70A.070(6). b. King County Code 14:80 -Intersection Standards: The traffic generated by this subdivision falls below the threshold requiring mitigation. c. King County Code 14. 75 -Mitigation Payment System: (MPS) requires the payment of a traffic impact mitigation fee (MPS fee) and an administration fee for each single-family residential lot or unit created. MPS fees are determined by the zone in which the site is located. This site is in Zone 342 per the MPS/Quarter section list. MPS fees may be paid at the time of final plat recording, or deferred until building permits are issued. The amount of the fee will be determined by the applicable fee ordinance at the time the fee is collected; currently the fee is $3,765. 5. Drainage: The western two thirds of the site slopes away from 1181h Avenue SE toward the east, to a natural wetland/swale that cuts the property diagonally in a southeasterly direction. The northeastern corner of the lot drains back toward the wetland. The wetland drains to the southeast and eventually to Soos Creek. The eastern half of parcel is proposed to be a critical area and drainage facility tract. The development lots are located on the western half of the property. This project is in the conservation flow control area and because the downstream drainage path ultimately goes through a sphagnum bog, it is subject to the sphagnum bog water quality menu. 6. School: This short plat has been reviewed under RCW 58.17.110 and KCC 21A.28 a. School Facilities: The subject subdivision will be served by Benson Hill Elementary, Nelson Middle and Lindberg Senior High School. b. School Impact Fees: Renton School District does not impose an impact fee per lot to fund school system improvements within this district. c. The School District busses the middle school students. The nearest bus stop is at 120'h Ave SE and Petrovitsky Road. Elementary and high school students currently walk to schools. It is noted that the elementary school is over 1 mile from the property. Safe walking paths for children to the stop and schools are provided along routes with sidewalks and/or road shoulders 5 feet or more in width, except that there are "spots" along 1161h Ave SE {the elementary school route) where the shoulder is 2-3 feet in width. 7. Parks and Recreation Space: KCC 21A.14 requires subdivisions in the UR and R zone classifications to either provide on-site recreation space or pay a fee to the Parks Division for establishment and maintenance of neighborhood parks. At this time the applicant is proposing to provide suitable recreation space east of Lot 6. The recreation tract, "Tract B" will also serve as a tract for the proposed drainage vault. The Subdivision Technical Committee concurs with the applicant's proposal. KCC 21A.14190 requires subdivisions to provide toUchildren play areas within the 10,453 s.f. Report & Recommendation L06S0043 March 28, 2008 Page 3 of 10 recreation space on site. A 400 square-foot play area with a tot lot or age appropriate play equipment is required. 8. Utilities: Sewage Disposal: The applicant proposes to serve the subject subdivision by means of a public sewer system managed by the Soos Creek Water & Sewer District. Initially, the sewer main was to run either east to the wetland buffer edge and then north or continue east through the wetland. Subsequently the sewer route design was revised to connect to the sewer main north on 1181h Ave SE and then to flow north in the main within the street right of way. Water Supply: The applicant proposes to serve the subject subdivision with a public water supply and distribution system managed by the Soos Creek Water and Sewer District with a 6" main, replacing existing main for 480 feet. 9. Fire Engineering: This proposal is consistent with KCC 21 A.28.130 standards for adequate fire protection. This project is located within the urban growth area. In accordance with KCC 20.44.080, no unusual circumstances related to the site or proposal have been found that result in adverse environmental impacts relating to fire protection that are not addressed by applicable regulations. The certificate of water availability submitted indicates that the minimum required fire flow of 1,000 gpm is available at the nearest fire hydrant 55 feet from the site. Any future residences constructed on Lots 3 through 6 must be sprinkled (NFPA 13D) due to inadequate fire apparatus access. The International Fire Code {IFC) requires all portions of the exterior walls (at grade) of the structures to be within 150 feet (as a person would walk via an approved route around the buildings) from approved fire apparatus access. Approved access is a minimum 20-foot wide (unobstructed) driving surface that is not over 150 feet in length if dead-end. Parked vehicles are an obstruction. The sprinkler requirement can be removed from lots 3 through 6 if the finished roadway driving surface is at least 28 feet wide, curb-to-curb, and the Fire Marshal designates one side of SE 1761h Place (within the short plat) as a fire lane. A formal request to King County Fire Engineering has to be initiated to accomplish this. The fire lane will have to be marked/signed in accordance with requirements outlined in Title 17 of the King County Code, and a covenant requiring the property owners to maintain the fire lane on the public roadway will have to be recorded. Because portions of the exterior walls of any residence constructed on lot 6 will be more than 150 feet (as a person would walk around it from approved fire apparatus access (unobstructed 20-foot wide driving surface) it will not be possible to remove the sprinkler requirement from lot 6. F. SEPA THRESHOLD DETERMINATION G. The initial submittal included establishment of an easement and construction of a sewer utility line which was to cross over the wetland on the east portion of the property. Subsequently, the project was revised. Both the easement and construction of the sewer line has been relocated to a totally different location away from the wetland. Therefore, under the provisions of the State Environmental Policy Act (SEPA), RCW 43.2C, the responsible official of the Land Use Services Division (LUSD) determined that the revised short plat request is exempt from SEPA COMMENTS RECEIVED No comments were received from the local residents of the neighborhood.
