Box 97034 EST -11W Bellevue, WA 98009-9734 RE: L10-043, Special Permission Director, Environmentally Sensitive Areas Deviation for Tree Trimming along 230Kv Transmission Line Corridor Dear Mr. Padvorac: The City received a Special Permission application from PSE in July 2010 for tree trimming. A notice of application was circulated to interested agencies. Comments were received from Muckleshoot Indian Tribe and were passed on to PSE, but no response was received from PSE to the comments. We subsequently had meetings with AECOM (PSE's consultants) to discuss PSE's long term vegetation management plan and discuss the requirements of City's sensitive areas regulations relative to hazardous trees. After our meetings with AECOM you indicated that you were thinking of withdrawing the Special Permission application for the trimming proposal and were going to resubmit after the long-term vegetation management plan was developed. We had meetings related to development of a long term plan in 2010 and 2011, and requested information from PSE to determine whether the long-term proposal to remove trees would meet the City's code requirements. We have received information from PSE related to periodic hot spot trimming, but we have not received follow-up communication in response to our request for additional information sent via email in June 2011. The Tukwila Department of Community Development (DCD) may cancel an application due to inactivity if the applicant fails to provide requested corrections or additional information within 90 days of the request under TMC 18.104.130. Your application for a Special Permission (L10-043/PL10-038) has therefore been canceled. Please contact me at (206) 431-3659 or Jaimie.Reavis(a,TukwilaWA.gov with any questions.

I understand that City code requires City review and acceptance of this report before PSE can submit permit applications to remove vegetation from wetlands. This submittal follows discussions between PSE and the City last fall, where the City requested additional information about PSE's plans to remove and trim vegetation under these transmission lines. As I mentioned to you last Friday, we would appreciate a timely review of the report, to be followed by a thorough site visit before vegetation fully leafs out. Full foliage of the trees and shrubs in the project area hides much of the plant structure, specifically the evidence of many years of topping underneath the transmission lines. Therefore, we would like to meet with you and other City staff the week of April 25th• The purpose of this meeting would be to present to City staff PSE's concept for mitigation and to conduct the thorough site visit mentioned above. Following input from the City at that meeting, PSE will create the mitigation plan at a level of detail that is required for the permitting process. Please call me with any questions about this project at (425) 456-2550 or on my cell phone at (206) 790-8153. Thank you!

The primary goal of the study is to provide information on wetlands that are likely to be affected by ongoing required vegetation maintenance activities by PSE along its transmission line corridors. The objectives of the study were to identify, map, categorize, and rate wetlands within the study area. A functional assessment of wetlands has also been completed. Field surveys were conducted in late November and early December, 2010. All study activities were completed in accordance with the requirements of the Tukwila Municipal Code. The study area consists of two separate sites: the 1.5 -acre Family Fun Center site located adjacent to the Green River in Township 23N, Range 4E, Section 24, and the Interurban site, a 1.2 -mile -long corridor that follows the Interurban Trail within Township 23N, Range 4E, Sections 24, 25, and 36. The Family Fun Center site includes a mitigation site constructed in 1998 to mitigate for loss of flood storage capacity and impacts to the Green River buffer associated with nearby development. The Interurban site includes a wetland mitigation easement area that the City of Tukwila (City) obtained from PSE in 1994 and subsequently planted to mitigate for impacts associated with the City's construction of a portion of the Interurban Trail. During field surveys, one wetland (Wetland FC) was delineated at the Family Fun Center site, and eight wetlands (Wetlands 1 through 8) were delineated at the Interurban site. A total of 38 sample plots were investigated to characterize the upland and wetland conditions within the study area. Table ES -1 provides a summary of the nine wetlands that were delineated during field surveys. Table ES -1.

Tukwila Wetland Delineation Report 60163731 April 2011 AECOM Report Environment ES -2 Wetland FC at the Family Fun Center site is a Category II riparian wetland that is influenced by freshwater tides. Wetlands at the Interurban site are generally located in closed depressions that do not discharge to ' other wetlands or streams. However, Wetland 8 is a depressional wetland that may have hydrological connectivity to other wetlands to the east via a culvert beneath the adjacent railroad tracks. Wetland 7 could potentially be a depressional outflow wetland to the Green River outside of the study area, although no culverts are shown in City mapping.

Following a preliminary site visit in late September 2010, field studies to delineate wetland boundaries were conducted in late November and early December 2010. This report provides information on wetlands that are likely to be affected by ongoing required vegetation maintenance activities by PSE along its transmission line corridors. 1.1 Project Background and Study Objectives In order to comply with recent mandatory reliability standards issued by the North American Reliability Corporation (NERC), PSE has adopted the practice of removing, topping, or trimming vegetation underneath and near 230 kV transmission lines that will reach mature heights of greater than 15 feet, or otherwise pose a safety risk. On two occasions in the summer of 2010, PSE trimmed vegetation on an emergency basis in response to potentially unsafe conditions near 230 kV transmission lines in Tukwila. In an effort to reduce the risk of non-compliance, minimize the need to react to emergency situations as they arise, and reduce maintenance costs, PSE plans to prepare, permit, and implement a Tong -term Vegetation Maintenance Plan (Plan) for its 230 kV transmission line corridor in the City. Because of the extra height of the steel transmission line towers in this corridor, PSE is considering allowing some tree species that may potentially exceed the height limit in areas near the towers. This comprehensive Plan will reference PSE's Energy Landscaping guidelines, and will detail the proposed vegetation maintenance approach, including Best Management Practices, post -maintenance restoration, and any necessary mitigation. Since the 230 kV line in a portion of the corridor is paralleled by two 115 kV lines, vegetation maintenance for the 115 kV lines will also be included in the Plan, which will consist of removing, topping, or trimming trees which could reach mature heights of greater than 25 feet. The 230 kV line and one of the 115 kV lines were constructed in the 1970s. The other 115 kV line was constructed in the 1980s. The objectives of the wetland delineation study were to identify, map, categorize, and rate wetlands within the study area. A more detailed functional assessment of the wetlands discussed in this report is included as Appendix A of this report. The information presented in this delineation report will be used to summarize wetlands that could potentially be affected by PSE's proposed vegetation maintenance activities, and to obtain environmental permits necessary for these proposed activities. 1.2 Regulatory Framework and Definitions The study area is located within the City of Tukwila (City). Regulations pertaining to wetlands in the study area are found in Tukwila Municipal Code (TMC) 18.45, Environmentally Sensitive Areas (Sensitive Areas Ordinance or SAO). According to TMC 18.06, wetlands are defined as follows: Areas that are inundated or saturated by groundwater or surface 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 bogs, swamps, marshes, ponds, lakes and similar areas. Wetlands do not include artificial wetlands intentionally created from non -wetland sites, including but not limited to irrigation and drainage ditches, grass - lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, landscape amenities or wetlands created after July 1, 1990 that were unintentionally created as a result of the construction of a road, street or highway. However, artificial wetlands intentionally created from non - wetland areas to mitigate conversion of wetlands as permitted by the City are considered wetlands. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 1-2 Additional City regulations that may apply to wetlands within the study area are found in TMC 18.45, Tree Regulations, and TMC 18.44, Shoreline Regulations. According to the SAO, wetland delineation must be performed in accordance with the Washington State Wetlands Identification and Delineation Manual (Washington Department of Ecology 1997). Wetland ratings must be designated in accordance with the. Washington State Wetlands Rating System for Westem Washington (Hruby 2004). Wetlands less than 1,000 square feet that are not associated with a riparian corridor, are not part of a wetland mosaic, do not contain habitat identified as essential for local populations of priority species identified by the Washington Department of Fish and Wildlife (WDFW), and do not score 20 points or greater for habitat in the Washington State Wetlands Rating System for Westem Washington may be exempted from regulation. 1.3 Description of Study Area PSE has identified two sites where vegetation maintenance activities are necessary (Figure 1-1) which together make up the study area for this delineation report. These sites are areas where vegetation is incompatible with existing transmission lines, or is likely to be so in the future. The Family Fun Center site is a 1.5 -acre area located northeast of the Family Fun Center along the Green River Trail; and the Interurban site is a 1.2 -mile corridor that runs along the Interurban Trail. 1.3.1 Family Fun Center Site The Family Fun Center site is located adjacent to and near River Mile 11 of the Green River, in Township 23 N, Range 4E, Section 24, Willamette Meridian (Figure 1-1). The site is oriented roughly northeast - southwest, along the 230 kV transmission line corridor. The transmission lines in this location span over portions of the developed areas associated with the Family Fun Center and the adjacent Comfort Suites hotel parking lot, as well as a portion of the paved Green River Trail and the undeveloped forested shoreline bluff to the river (Figure 1-2). The Family Fun Center site is located within the 200 -foot -wide City -regulated riparian shoreline buffer. The majority of the site (north and east of the Green River Trail) is part of a feature that was constructed, with fish and wildlife habitat enhancements, as mitigation for impacts to the river buffer and floodplain storage capacity. Additional information about the mitigation site is provided in Section 3.3 and Appendix B. According to the City's zoning map (City of Tukwila 2008), the Family Fun Center site is zoned as Commercial/Light Industrial. 1.3.2 Interurban Site The Interurban site is located within Township 23 N, Range 4E, sections 24, 25, and 36, Willamette Meridian. It is oriented north -south, and runs adjacent to the West Valley Highway (on the west), and the Union Pacific Railroad (on the east; Figures 1-1 and 1-3). The site includes the Interurban Trail, which is located in the western half of PSE's corridor. The Green River runs roughly parallel to the site, west of the West Valley Highway, with urban development located between the site and the river. At its closest point (near 16197 West Valley Highway), the Green River comes within 175 feet of the site. The Interuruban site consists of a double circuit 230 kV transmission line on steel towers, flanked by 115 kV lines on each side. The site starts at approximately the south edge of the Embassy Suites Hotel and ends at South 180`h Street. The total area of the site is approximately 21.1 acres. However, not all of this area has the potential to support vegetation that would require maintenance by PSE. The steel towers are located on 100 -foot -wide parcels owned by PSE, 56.5 feet east of the property line. Much of the Interurban site extends east beyond the PSE parcel on land rights that PSE previously acquired from Union Pacific Railroad for the construction and maintenance of a 115 kV transmission line. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 1-3 The land located to the west of PSE's parcel consists of businesses and other developed areas, with a vegetated strip of varying widths between paved (or otherwise developed) areas associated with these properties and the Interurban Trail. The portion of the site to the east of the trail is undeveloped along the vast majority of the corridor, consisting of disturbed grass and Himalayan blackberry (Rubus armeniacus) dominated communities, and scrub -shrub communities typified by dense stands of willows (Salix spp.) in wetter areas. Included in these wet areas is a0.6 -acre easement that PSE granted to the City in 1994 for wetland mitigation to compensate for wetland impacts associated with the City's construction of the Interurban Trail (see Section 3.3 and Appendix B for more information). The undeveloped area continues to the east until it hits the raised berm associated with the Union Pacific Railroad. This railroad line is currently very actively used, as is the BNSF Burlington Northem Santa Fe Railroad located further to the east. Portions of the undeveloped area have been disturbed by clearing, deposition of fill, and other activities. Various underground pipelines run through the area. Additionally, two railroad spurs cut through the Interurban site, creating breaks in the vegetation. Within in the Interurban site, trees have been repeatedly topped to maintain a safe clearance from the overhead transmission lines. It is common to see tree stems with a diameter at breast height (dbh) of 12 inches or more that are only 15 to 20 feet tall, with a very bushy and tall cluster of fast-growing sprouts at the top.

These materials included the following: • Aerial photos of the study area. • GIS data provided by PSE showing locations of transmission lines, towers/poles, and previously - identified hazard trees. • City of Tukwila GIS data layers showing locations of mapped wetlands and other critical areas. • City of Tukwila GIS storm data showing locations of catch basins, drain points, pipes and ditches, storm detention ponds, and storm pump stations. • National Wetland Inventory (NWI) maps (U.S. Fish and Wildlife Service 1977 to present). • Historical information about mitigation sites within the study area, obtained from the City. • Soil Survey of King County Area, Washington (Snyder et al. 1973). • WDFW Priority Habitats and Species GIS data (WDFW 2010). • Data on climatic conditions, such as precipitation and temperature (Western Regional Climate Center 2010; Weather Underground 2010). • Water lever tide predictions (National Oceanic and Atmospheric Administration 2010). Results of the background review are presented in Chapter 3.0. 2.2 Wetland Delineation and Rating As required by City regulations (TMC 18.45.080), the wetland delineation methodology follows the Washington State Wetlands Identification and Delineation Manual, which provides guidelines for determining whether an area should be classified as a wetland. 2.2.1 Wetland Delineation Criteria According to the manual, an area must exhibit evidence of at least one positive wetland indicator from each of the following parameters to be defined as a wetland: Vegetation — The land supports predominantly hydrophytic vegetation (macrophytes that are able to grow in water or on a substrate that is at least periodically deficient in oxygen). Soils —The substrate is predominantly undrained hydric soil, or soils possess characteristics associated with reducing soil conditions. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 2-2 Hydrology— The area is inundated either permanently or periodically at a mean water depth of less than 6.9 feet, or the soil is saturated to the surface at some time during the growing season of the prevalent vegetation. The growing season is defined as the portion of the year when the soil temperature 19.7 inches below the soil surface is greater than biological zero (41 °F). This period is usually approximately by the number of frost -free days for an area (Washington Department of Ecology 1997). 2.2.2 Characteristics of Hydrophytic Vegetation Hydrophytic vegetation is defined as macrophytic plant life growing in water or soil or on substrate that is at least periodically deficient in oxygen as a result of excessive water content (U.S. Army Corps of Engineers 1987). A list of plants able to tolerate saturated soil conditions has been prepared by the U.S. Fish and Wildlife Service (USFWS; Reed 1988; USFWS 1993). Vascular plants are classified according to their affinity for wetland areas, and thus their probability of being found in a wetland. There are five wetland indicator status ratings, as defined below: Obligate Wetland (OBL): Under natural conditions, plants occur almost exclusively in wetlands (estimated probability >99 percent) Facultative Wetland (FACW): Plants usually occur in wetlands (estimated probability 67 to 99 percent), but are occasionally found in non -wetlands. Facultative (FAC): Plants are equally likely to occur in wetlands and non -wetlands (estimated probability 34 to 66 percent). Facultative Upland (FACU): Plants usually occur in non -wetlands (estimated probability 67 to 99 percent), but are occasionally found in wetlands (estimated probability 1 to 33 percent). Obligate Upland (UPL): Plants may occur in wetlands in another region, but under natural conditions almost always occur in non -wetlands in the region specified (estimated probability >99 percent). The three facultative categories are further subdivided by (+) and (-) modifiers. FAC+ species have a greater estimated probability of occurring in wetlands than FAC species, while FAC- species are considered to have a lesser estimated probability of occurring in wetlands than FAC species (Reed 1988; USFWS1993). Wetland indicator categories should not be equated to degrees of wetness. Many Obligate Wetland species occur in permanently or semipermanently flooded wetlands, but some also occur in, or are restricted to, wetlands that are only temporarily or seasonally flooded. The actual frequency of occurrence of a species in wetlands may be anywhere within the frequency range of the indicator category. For example, a species assigned to the Facultative Upland indicator category may actually have a frequency toward the upper end of the category (Reed 1988). The presence of hydrophytic vegetation is determined using the wetland indicator status of species encountered. Hydrophytic plants are those rated as FACW or wetter. Wetland boundaries are identified based on the presence of a wetland plant community, rather than any one particular indicator species. For example, a plant community with scattered individual upland species, but dominated by hydrophytic species, is considered to be a wetland community. Within each wetland, specific communities are determined on the basis of their dominant plant species, soils, and hydrology. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 2-3 2.2.3 Characteristics of Hydric Soil Hydric soils are flooded, ponded, or saturated long enough during the growing season to develop anaerobic conditions in the upper part of the soil profile (U.S. Department of Agriculture Soil Conservation Service 1991). Anaerobic conditions are created when flooding, ponding, or saturation is of sufficient duration to eliminate oxygen from the environment. These soils usually support hydrophytic vegetation. The National Technical Committee of Hydric Soils developed criteria for hydric soils and published a list of the Nation's hydric soil types (National Resource Conservation Service 2010, most recently). Because they are saturated during the growing season, hydric soils usually develop certain morphological features that can be observed in the field. A prolonged anaerobic environment typically lowers the soil redox potential and causes a chemical reduction of soil components, such as iron and manganese oxides. This reduction affects solubility, movement, and aggregations of these oxides, and is often visible in the soil coloration. The duration and depth of soil saturation are used to identify hydric soils and wetlands. Soil physical features such as color as commonly used to indicate long-term soil moisture regimes. The most widely recognized colors that reflect wetness in mineral soils are low chromas (grayish) with or without high chroma (yellow/red) mottles. Subsurface horizons in hydric soils are predominantly neutral gray in color and occasionally greenish or bluish. The distinctive colors result from a process known as gleization, in which prolonged saturation of mineral soil converts iron from its oxidized (ferric) form to its reduced (ferrous) state. The reduced compounds may be completely removed from the soil, resulting in low chromas. Mineral soils that are always saturated are uniformly gleyed throughout the saturated zone. Soils gleyed to the upper surface layer (within 12 inches of the surface) are hydric soils. Mineral soils that are alternately saturated and oxidized (aerated) during the year are usually mottled in the part of the soil that is seasonally wet. Mottles are spots or blotches of contrasting colors or shades of colors interspersed with the dominant (matrix) color. The abundance, size, and color of the mottles usually reflects the duration of the saturation period. Mineral soils that are predominantly grayish with brown or yellow mottles in the upper 20 inches are usually saturated for long periods during the growing season and are commonly classified as hydric. Color chromas of 2 or Tess, using the Munsell color system, are considered low chromas and are often diagnostic of hydric soils (Munsell Color 1990). An example of a soil color that would be classified as hydric is 5YR 5/1 (the number after the slash indicates the soil's chroma). Low chroma colors include black, various shades of gray, and darker shades of brown and red. Soils that are predominantly brown or yellow with few gray mottles may be saturated for shorter periods and generally are not hydric. Mineral soils that are never saturated are usually brightly colored without mottles. Two examples of soil colors that would not be classified as hydric are 5YR 5/4 and 10YR 7/3. 2.2.4 Characteristics of Wetland Hydrology Permanent or periodic inundation (in which soil is at least seasonally saturated within the rooting zone) is the hydrologic force behind wetland formation. The presence of water for 5 percent or more of the growing season typically creates an anaerobic condition in the soil, which affects the types of plants that grow and the types of soils that develop (U.S. Army Corps of Engineers 1987). Numerous factors influence the wetness of an area: precipitation, stratigraphy (i.e., layering), topography and micro relief, and soil permeability. The water found in wetlands may come from direct precipitation, overbank flooding, surface water runoff, groundwater discharge, or tidal flooding. The frequency and duration of inundation and soil saturation vary widely, and may be permanent or intermittent. The duration of inundation or saturation is usually the most important factor affecting soils and vegetation. Soil permeability, which is affected by soil texture and density, influences the duration of inundation and soil saturation. For example, soils with high clay content generally have lower permeability, absorb water more slowly, and remain saturated for a longer period of time that sandy or loamy soils. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 2-4 Of the three technical criteria for wetland identification, wetland hydrology is often the least exact and most difficult to characterize, primarily because of annual, seasonal, and daily fluctuations in water level. An area has wetland hydrology when saturated within the rooting zone (usually within 12 inches of the surface) for at least 5 percent of the growing season. The water table can be defined as the upper surface of groundwater, or the level below which the soil is saturated with water (U.S. Army Corps of Engineers 1987). A water table is at least 6 inches thick and persists in the soil for more than a few weeks. Other field indicators used as evidence of wetland hydrology include ordinary high water marks, drift lines, drainage patterns, watermarks, sediment deposition, vegetation morphology (e.g., adventitious roots), and presence of algae or moss. In areas where hydrology evidence is weak or lacking, the FAC neutral test may be employed to corroborate the presence of sufficient hydrology as a secondary indicator. The test is applied by comparing the number of dominant plant species that have indicator statuses of FACW and OBL with the number of dominants listed as FACU and UPL, thus ignoring the FAC dominants). If the number of dominants that are FACW or wetter is greater than the number of dominants that are FACU or drier, the FAC neutral test is positive, inferring that the plant community is reflecting the presence of wetland hydrology. If there is a tie, the number of FAC+ dominants is compared to the number of FAC- dominants to apply to determine the results of the test. If a tie ensues, non-dominant species are examined to determine how strongly hydrophytic the vegetation is represented. When primary indicators of wetland hydrology (visual observation of inundation/saturated soils within 12 inches of the surface) are not present, at least two secondary indicators must be positive in order to infer positive wetland hydrology 2.2.5 Cowardin Classification Wetlands delineated in the study area are classified using the USFWS wetland hierarchical classification system (Cowardin et al. 1979). This system classifies wetland according to hydrologic, geomorphologic, chemical, and biological factors. Wetlands are first classified by the primary source of water to the wetland. These classes are usually identified by the physical form of the dominant plant community type, or Tess often, the substrate of the wetland. Only one type of primary wetland system, palustrine, is applicable to wetlands within the study site. Palustrine systems are shallow ponds and wet areas, including all non -tidal wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens. This system includes wetlands lacking such vegetation, but with all of the following four characteristics: 1) total area is less than 8 hectares (20 acres); 2) active wave -formed or bedrock shoreline features are lacking; 3) water depth in the deepest part of the basin is less than 6.6 feet (2 meters) at low water; and 4) salinity, due to ocean -derived salts, is Tess than 0.5 parts per thousand. Descriptions of other wetland systems may be found in Cowardin et al. (1979). Systems are divided into more specific categories called subsystems, although there are no subsystems within the Palustrine system. The classification system further identifies wetlands by dividing them into different classes based on the general appearance of the life form in the plant community (e.g., trees, shrubs, aquatic vegetation), and subclasses based on finer differences in life form. Palustrine classes pertinent to the study area include Forested, Scrub -Shrub, and Emergent. These classes are defined as follows (definitions from Cowardin et al. 1979): Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 2-5 Forested — Characterized by woody vegetation that is 6 meters (19.7 feet) or taller (abbreviated as PFO in this report). Scrub -Shrub — Dominated by woody vegetation less than 6 meters (19.7 feet tall). The species include shrubs, young trees, and trees or shrubs that are small or stunted because of environmental conditions (abbreviated as PSS). Emergent — Characterized by erect, rooted, herbaceous hydrophytes, excluding mosses and lichens. This vegetation is present for most of the growing season in most years. These wetlands are usually dominated by perennial plants (abbreviated as PEM). Palustrine classes normally found within the stream channel (rock bottom, unconsolidated bottom, aquatic bed, and unconsolidated shore) are classified in this report as Open Water (abbreviated as POW). 2.2.6 Hydrogeomorphic Classification The way wetlands function is highly dependent on their hydrologic and geomorphic conditions (Brinson 1993). The hydrogeomorphic (HGM) classification system groups wetlands into categories based on the hydrologic and geomorphic characteristics that control many functions (Hruby 2004). For the purposes of wetland delineation and rating, identification of the wetland HGM wetland class is an important tool. The Washington State Wetland Rating System for Westem Washington distinguishes between the following six HGM classes (descriptions are taken from Hruby 2004): Tidal Fringe — wetlands found along the coasts and in river mouths to the extent of tidal influence. The dominant source of water is from the ocean or river. The unifying characteristic of this class is the• hydrodynamics: all tidal fringe wetlands have water flows dominated by tidal influences, and water depths controlled by tidal cycles in the adjacent ocean. Flats — wetlands that occur in topographically flat areas that are hydrologically isolated from surrounding groundwater or surface water. The main source of water is precipitation directly on the wetland itself. Flats wetlands receive virtually no groundwater discharge or surface runoff from the surrounding landscape, a characteristic that distinguishes flats wetlands from depressional and slope wetlands. Lake -Fringe — wetlands that are separated from other wetlands based on the area and depth of open water adjacent to them. If the area of open water next to a vegetated wetland is larger than 20 acres (8 hectares), and more than 6.6 feet (2 meters) deep over 30 percent of the open water areas, the HGM class of the wetland is lake -fringe. Slope — wetlands that occur on hill or valley slopes where groundwater daylights and begins running along the surface or immediately below the soil surface. Water in these wetlands flows in only one direction (down the slope), and the gradient is steep enough that the water is not impounded. The "downhill" side of the wetland is always the point of lowest elevation in the wetland. Riverine — Wetlands that occur in valleys associated with stream or river channels. They lie in the active floodplain of a river, and have important hydrologic links to the water dynamics of the river or stream. The distinguishing characteristic of riverine wetlands in Washington is that they are frequently flooded by overbank flow from the stream or river, and the floodwater is a major environmental factor that structures the ecosystem in riverine wetlands. Riverine wetlands may also receive significant amounts of water from other sources such as groundwater and slope discharges. Wetlands that lie in the floodplain but are not frequently flooded are not classified as riverine. Depressional — wetlands that occur in depressions where elevations within the wetland are lower than the surrounding landscape. The shapes of depressional wetlands vary, but in all cases the movement of surface Tukwila Wetland Delineation Report • April 2011 60163731 AECOM Report Environment 2-6 water and shallow subsurface water is toward the lowest point in the depression. The depression may have an outlet, but the lowest point in the wetland is somewhere within the boundary, rather than at the outlet. In some cases, multiple HGM classes occur within one wetland boundary. 2.2.7 Wetland Rating As required under Tukwila's recently adopted (August 2010) SAO (18.45.080), wetlands delineated in the study area were rated in accordance with the Washington State Wetlands Rating System for Westem Washington. This system scores wetlands on the basis of their sensitivity to disturbance, the functions they provide, and whether they can be replaced. Based on a series of questions about attributes of the wetland and the surrounding areas, scores pertaining to water quality functions, hydrologic functions, and habitat functions are generated. In some cases, wetlands may also be categorized on the basis of special characteristics. There are four categories of wetlands, which are briefly described below: Category 1 Wetlands that 1) represent a unique or rare wetland type; or 2) are more sensitive to disturbance than most wetlands; or 3) are relatively undisturbed and contain ecological attributes that are impossible to replace within a human lifetime; or 4) provide a high level of functions. Types of Category I wetlands that are potentially found in Tukwila include estuarine wetlands and wetlands that perform many functions and score at least 70 points on the Washington State Wetlands Ratings System for Westem Washington. Category II Wetlands that are difficult, though not impossible, to replace and provide high levels of some functions. These wetlands occur more commonly than Category I wetlands, but still need a relatively high level of protection. Types of Category II wetlands that are potentially found in Tukwila include estuarine wetlands smaller than 1 acre, or those that are disturbed and larger than 1 acre, and wetlands that perform functions well (scoring between 51 and 69 points on the Washington State Wetlands Ratings System for Westem Washington. Category III Wetlands that have a moderate level of functions (scores between 30 and 50 points). These wetlands are generally disturbed in some ways and are often less diverse or more isolated from other natural resources in the landscape than Category II wetlands. Category IV Wetlands that have the lowest levels of functions (scores less than 30 points) and that are often heavily disturbed. While these are wetlands that should be able to be replaced or improved, they still need protection because they may provide some important functions. Any disturbance of these wetlands will be considered on a case by case basis. The adoption of the Washington State rating system under the 2010 SAO was a modification of the previous (2004) SAO, which included a City -specific wetland rating system. Wetlands within the study area, as mapped by the City, are still classified under the City's rating system. Based on a memorandum from the City Department of Community Development (2010), these ratings are provisional. 2.2.8 Field Evaluation A field survey of the study area was conducted on November 30 through December 3, 2010 to identify, delineate, categorize, and map wetlands occurring on the Family Fun Center and Interurban sites. Field evaluations followed methodology presented in the Washington State Wetlands Identification and Delineation Manual. Wetlands were first rated during the preliminary site investigation on September 27, 2010. Following the complete delineation of the study area, these ratings were revisited based on the new information obtained, and modified as appropriate. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 2-7 Family Fun Center Site. Given the small area of the site and the steep slopes, surveyors meandered through the entire area from the base of the slope to the edge of the river channel to investigate areas with apparently different vegetation and soils from the upland slope forest. Surveyors dug one or more small soil holes in these areas to determine soil characteristics, and noted the plant species present. Interurban Site. The wetlands in this area are long and linear, and bounded on both long edges by obvious upland fill areas. To delineate wetland boundaries, AECOM biologists ran east -west transects at intermittent points along the wetlands, documenting upland, wetland, and upland -wetland transitional conditions on data sheets. Because of access and safety issues associated with the Union Pacific Railroad, the eastern edges of wetlands to the east of the Interurban Trail were not delineated. It was determined that this boundary corresponded with the base of the berm for the railroad tracks, which could be professionally surveyed without being flagged. Where the wetland boundary was observed to move away from the railroad berm (particularly at the north and sound ends of wetlands), the boundary was delineated and flagged. Wetlands located on the west side of the Interurban Trail were delineated and flagged, with the exception of one wetland that extended west a considerable distance beyond the study area. The portions of this wetland that extended beyond the study area were not delineated (see Wetland 7 on Figure 4-2). Although fill and other site disturbances associated with urban development, railroad tracks, recreational trails, and utility installations (fiber optic cables, petroleum and sewer pipelines, and overhead transmission lines) have occurred within both the Family Fun Center and Interurban sites, disturbances to wetlands were not considered significant, for the purposes of delineation. AECOM biologists determined that normal circumstances, in regards to assessment of wetland conditions, existed in both portions of the study area; the site conditions did not warrant delineating wetlands according to the methodology required for atypical situations or potential problem areas. Boundaries of all wetlands were flagged and numbered, and marked by hand on aerial photos of the site. AECOM biologists mapped the locations of all sample plots (soil log holes) and the boundaries between different Cowardin classes with Trimble GeoXT and Garmin GPSMAP 60 handheld Global Positioning System (GPS) units. Flagged wetland boundaries were professional surveyed by David Evans and Associates on December 6 through December 9, 2010. During field surveys, biologists noted any wildlife species that were encountered, paying particular attention to native and priority species. Photographs documenting the site conditions at the time of field surveys are included as Appendix C of this report. Completed field data forms can be found in Appendix D. Completed wetland rating forms are provided in Appendix E. • Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 3-1 3.0 Results of Background Review 3.1 Wetlands According to City mapping, there are nine individual wetlands within the Interurban site (Figure 3-1). Prior to the current delineation, the presence of these wetlands was confirmed during a site visit by AECOM biologists, although a few apparent discrepancies between the GIS mapping and field conditions were noted. These wetlands occur along much of the Interurban Trail corridor. NWI maps show wetlands adjacent to the Interurban site to the east, with a small portion of overlap in the study area. The NWI maps also show a wetland west of the study area near the southern end of the Interurban site. No wetlands have been previously mapped at the Family Fun Center site, either by the City or on NWI maps. However, the adjacent Green River is identified on both sets of maps. 3.2 Other Critical Areas According to City maps, no abandoned mine areas or fish and wildlife habitat conservation areas occur at. the Interurban site or the Family Fun Center site. No watercourses are mapped within the Interurban site boundary, although a very small portion of the site is located within the shoreline management zone. The Family Fun Center site is located entirely within the shoreline management zone. No watercourses are mapped on the site, but it is directly adjacent to the Green River. It is also located within a mapped potential landslide hazard area. 3.3 Historical review A search of City land use planning permit records revealed information about three mitigation sites in the vicinity of the study area, two of which occur within the PSE transmission line corridor. A third mitigation site occurs near the southwestern portion of the study area, on property adjacent to PSE's. Because this mitigation site is outside the study area, it would not be affected by proposed vegetation maintenance activities. More detailed information about these sites is provided in Appendix B. The City wetland mitigation site includes two wetlands located on PSE's property, on an easement granted to the City. These wetlands were created following issuance of the easement in 1994 to mitigate for impacts associated with construction of the Interurban Trail by the City. The Family Fun Center mitigation site is located on property owned by the Family Fun Center development, It is a compensatory flood storage excavation area (with plantings to enhance fish and wildlife habitat) within the floodplain of the Green River, that includes a riverbank shelf and off -channel pond. The site was constructed in 1998 to mitigate for loss of 100 -year floodplain storage capacity and impacts to the Green River buffer. Construction of the Family Fun Center and adjacent Comfort Suites included filling an extensive area of floodplain. Mitigation for these impacts entailed excavating an area of compensatory flood storage, which was done adjacent to the river, underneath the transmission lines. The excavated area was then planted to enhance fish and wildlife habitat. Some of the planted and volunteer vegetation in this mitigation area now poses a threat to the transmission lines by creating reduced clearance. The Family Fun Center is responsible for maintaining this mitigation site.

Soils at the Family Fun Center site are mapped as urban land (Snyder et al. 1973). This map unit consists of soils that have been modified by disturbance of nature layers with additions of fill material several feet thick to accommodate large industrial and housing installations. In the Green River Valley, gravelly sandy loam to gravelly loam fill ranges from about 3 to more than 12 feet in thickness. Soils in the Interurban site are mapped as Newberg silt loam, Puget silty clay loam, Woodinville silt loam, and Puyallup fine sandy loam (Snyder et al. 1983; Appendix F). The Puget and Woodinville soils are on the Washington State hydric soils list (National Resource Conservation Service 2010). Hydric inclusions may be present within the Newberg and Puyallup soil units. Newberg silt loams are well -drained soils with moderate permeability and high available water capacity that formed in alluvium in stream valleys with slopes between 0 and 2 percent. Runoff is slow, and the erosion hazard is slight, but the hazard of stream overflow is slight to severe. Brief occasional flooding may be present from December through March, but frequent ponding is not characteristic. The water table is located at depths greater than 3 to 4 feet from February to April. The Puget soil series is made up of poorly drained soils with slow permeability located in small depressions of river valleys with slopes of 1 percent or less. Seasonal frequent flooding and ponding may be present from December through March, and frequent ponding may extend through May. The seasonal high water table is at or near the surface. Runoff is slow to ponded, and the erosion hazard is slight. Stream overflow is a severe hazard. The Woodinville series is made up of nearly level and gently undulating poorly drained soils that formed in alluvium, on stream bottoms with slopes less than 2 percent in gradient. Permeability is moderately slow, and a seasonal high water table is present at or near the surface to a depth of 12 inches. Stream overflow is a severe hazard, and brief frequent flooding may occur from October through April. Frequent ponding is not associated with this unit. The Puyallup fine sandy loam is a well -drained soil located on floodplains and terraces with 0 to 2 percent slopes. Available water capacity is low. Brief occasional flooding may occur; however, ponding. is not associated with this soil unit. 3.5 Priority Habitats and Species According to digital data from WDFW (2010), there are no priority habitats or species, apart from wetlands, within the Interurban site. The nearest listed priority habitat is "Longacres Wetlands," a portion of which is located approximately 300 east of the study area at its closest point. Two sets of railroad tracks run between the Interurban wetlands and this priority habitat. Digital storm data (catch basins, drain points, pipes and ditches, storm detention ponds, and storm pump stations) from the City do not indicate any hydrological connectivity via culverts or other manmade features between the Longacres wetlands and the interurban site. The Longacres Wetlands are described as "forested, scrub -shrub, and emergent wetlands, excellent waterfowl, passerine bird and raptor habitat, likely to support populations of amphibians, reptiles, and small mammals." An osprey (Pandion haliaetus) nest has been mapped just outside the study area, on a cell tower behind the Embassy Suites hotel. Osprey is not a listed or priority species, but the occurrence of this nest shows up on digital data obtained from WDFW. This nest is located approximately 75 feet east of PSE transmission lines, and is approximately 120 feet north of the northern boundary of the study area covered by this delineation (South Longacres Way). Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 3-4 The Green River within the general vicinity of the study area supports populations of listed and sensitive salmonid species, including summer and fall chinook salmon, fall chum salmon, coho salmon, pink salmon, sockeye salmon, summer and winter steelhead trout, resident cutthroat trout, and bull trout/Dolly Varden. Although wetlands at the Interurban site are not suitable for use by these species because there is no apparent hydrologic connection between the wetlands and the Green River, the off -channel habitat at the Family Fun Center site could potentially be used by all of these species. No additional priority habitats or species occur in or near the Family Fun Center site. 3.6 Climatic Conditions The climatic conditions prior to and during the field investigation were obtained from the nearest Weather Underground -affiliated weather station (located less than 1.4 miles west of the study area; Weather Underground 2010). The average air temperature during the dates of the field investigation (November 30 to December 3, 2010) was 42 degrees Fahrenheit. Daily high temperatures did not exceed 49 degrees and daily lows did not approach freezing conditions during the field investigation. In the week prior to the field investigation, killing frosts were recorded daily at this local weather station and throughout the region. Therefore, all wetland delineations were conducted outside of the growing season. According to local weather station data, precipitation was recorded during two days of the field investigations: 0.48 inches on November 30 and 0.01 inches on December 2 (Weather Underground 2010). Annual normal precipitation for the Seattle -Tacoma (SeaTac) International airport, located approximately 4.6 miles west of the study area is 37.19 inches (based on data from 1961 through 1990; Western Regional Climate Center 2010). More than 5 inches of precipitation are typically recorded during each of the months January, November, and December. Comparably, less than 1 inch of precipitation is typically recorded in July, normally the driest month of the year. During the month of November 2010, 5.05 inches of precipitation were recorded at SeaTac airport (Western Regional Climate Center 2010) and 4.61 inches were recorded at the weather station nearest to the study area (Weather Underground 2010). As of December 22, the 2010 year-to-date summary for precipitation at this local station was 31.27 inches. Based on this information, it is assumed that normal conditions of precipitation existed in the study area, and that field observations for indicators of wetland hydrology were made under normal climatic conditions. 3.7 Tides The Green River in the vicinity of the study area is influenced by tides. The upstream limit of tidal influence within the Duwamish River/Waterway is located within the Green River at River Mile 12.5, approximately 1 mile upstream of the study area. Surveys at the Family Fun Center site were conducted on November 30 and December 1, 2010, between the hours of 8:00 a.m. and 12:00 p.m. Tide tables for the nearest water - level station on the Duwamish Waterway predicted +11.8 -foot -high tides at 11:54 a.m. on November 30 and at 12:36 p.m. on December 1 (National Oceanic and Atmospheric Administration 2010). The tide tables predicted early morning low tides of +3.4 feet at 5:13 a.m. on November 30 and +4.8 feet at 6:23 a.m. on December 1. Based on this information, the field surveys at the Family Fun Center site were conducted during incoming or flooding tides. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 4-1 4.0 Results of Field Evaluation 4.1 Wetland Descriptions During field surveys, one wetland (Wetland FC) was delineated at the Family Fun Center site, and eight wetlands (Wetlands 1 through 8) were delineated at the Interurban site (Figures 4-1 and 4-2). A total of 38 sample plots were investigated during the field study to' characterize the upland and wetland conditions within the study area (Figures 4-1, 4-3 through 4-11). Three of these sample plots were located at the Family Fun Center site, and the remainder were located at the Interurban site. Table 4-1 provides information on the general location of each sample plot, as well as findings pertaining to the wetland parameters vegetation, soils, and hydrology. The wetlands that were delineated during field surveys are described in more detail in the sections that follow. Additional information about these wetlands can be found in the Functional Assessment in Appendix A, on the field data forms in Appendix D, and on the wetland rating forms in Appendix E. Locations of numbered sample plots referenced in the wetland descriptions are shown on the associated figures for each wetland found at the end of this chapter. 4.1.1 Family Fun Center Site 4.1.1.1 Wetland FC Wetland FC is a freshwater, tidally influenced, riparian PFO/PSS wetland, approximately 10,200 square feet (0.23 acres) in size (Figure 4-1). As discussed in Section 3.3 and Appendix B, this wetland was created in 1998 to provide increased side channel fish habitat and flood storage capacity adjacent to the Green River. The wetland is connected to the Green River via a cut drainage channel. Large rocks and an earthern berm bound the northern edge of the wetland, separating it from the river. The eastern end of the wetland is bounded by railroad tracks and its southern boundary is situated along the toe of the shoreline slope. Wetland FC was rated as a Category II wetland, receiving a score of 55 points on the rating form (Appendix E). Large woody debris has been installed within the wetland to enhance habitat within the wetland. Additional information regarding its functional ratings is included in Appendix A. Vegetation. The wetland vegetation is dominated by dense willows (Scouler's willow [Salix scouleriana], Pacific willow [S. lucida var. lasiandra], and Sitka willow [S. stichenses]), but also includes a wide variety of Targe tree species. Understory dominants include Himalayan blackberry and redosier dogwood (Comus sericea), and in some locations, reed canarygrass (Phalaris arundinacea). Some vine maple (Acer circinatum) is also present. Soils. Dark grayish brown (10 YR 4/2) silt loams were observed at each of the three sample plots (FCS1, FCS2, and FCS3) within the Family Fun Center site. Locations of these sample plots are shown in Figure 4- 1. At the wetland sample plot (FCS1), located on the riparian bench within the wetland, hydric indicators of coarse distinct to prominent brown/strong brown (7.5 YR 4/4 to 4/6) mottles were observed at depths below 4 inches from the ground surface. At the wetland/upland transitional sample plot (FCS2), non -hydric, very dark brown (10 YR 2/2) top soils were present within the upper 6 inches. At depths below 6 inches, the soils displayed faint brown (10 YR 4/3) mottles. At the upland sample plot (FCS3), situated upslope of FCS1 and FCS2, sandy silt loams (10 YR 4/2) lacking in hydric indicators (mottles) were observed. Hydrology. The main source of hydrology at Wetland FC is associated with the ebbs and flows of the Green River. Precipitation and ground water are additional sources of hydrology_ Tukwila Wetland Delineation Report , April 2011 60163731 AECOM Report Table 4-1.

The bankful width of the manmade inflow/outflow drainage channel measures 20 feet. At mid-morning on the first day of the investigation (November 30), the bankful width of the channel was completely inundated. On the following morning, when the incoming high tide was to occur an hour later than the previous morning, the width of the wetted channel within the cut drainage measured only 4 feet and the majority of the bankful width was exposed. 4.1.1.2 Adjacent Upland Areas A fence at the top of the shoreline bluff is the upslope boundary of the shoreline enhancement area. Non- native Himalayan blackberry and Scotch broom (Cytisus scoparius) and other invasive species, including common tansy (Tanacetum vulgare), Robert geranium (Geranium robertianum), tall buttercup (Ranunculus acris) and field horsetail (Equisetum arvense), are present along the edge of the trail. Vegetation outside of the fenced area is mowed on a regular basis. Periodic maintenance of vegetation growing on the forested slope to the river has been performed by PSE to provide appropriate clearance beneath the transmission lines. The dominant canopy species in this area include red alder (Alnus rubra), bigleaf maple (Acermacrophyllum), black cottonwood (Populus balsamifera spp. trichocarpa), and westem redcedar (Thuja plicata), with a few lodgepole pines (Pinus contorta) also present. The base of the slope adjacent to the ordinary high water mark of the Green River was investigated for the presence of other wetlands associated with shoreline and riparian areas. Evidence of sediment deposition and erosion associated with past flooding was observed on a series of riparian benches adjacent to the River. Although not formally delineated by AECOM biologists, the ordinary high water mark was noted at the base of the shoreline slope or along the top of the highest elevated riparian bench, where the vegetation transitioned from hydrophytic reed canarygrass to non-hydrophytic Himalayan blackberry. Non-native and invasive Japanese knotweed (Polygonum cuspidatum) was also observed along the river edge. Non -hydric very dark brown (10 YR 2/2) and dark grayish brown (10 YR 4/2) soils with no mottles were observed along the shoreline benches; therefore, these areas were not delineated as shoreline -associated wetlands. 4.1.2 Interurban Site 4.1.2.1 Wetland 1 Wetland 1 is one of two wetlands delineated east of the Interurban Trail, between Strander Boulevard and PSE Tower 3/9 (Figures 4-3 through 4-5). Although City maps identify one linear wetland in this area, AECOM biologists observed that this -City mapped wetland was actually bisected by upland into two separate wetlands (Wetlands 1 and 2). Wetland 1 is a small, PSS wetland situated within a shallow depression that is bounded on the west by bermed railroad tracks (Figure 4-3). It is seasonally saturated/inundated, and approximately 1,128 square feet (0.03 acres) in size. Wetland 1 is a Category III wetland, receiving a score of 36 points on the rating form (Appendix E). A fiber-optic cable is present within the immediate vicinity of this wetland. Additionally, the City's storm data indicates that there is a drain point just north of Wetland 1, and a pipe that runs under Strander Boulevard, discharging north of the road (Figure 4-3). Vegetation. The vegetation within Wetland 1 is dominated by Pacific, Scouler's, and Sitka willows. At the time of surveys, protective net webbing was wrapped around the trunks of many of the larger trees and shrubs. Although much of the ground surface within the wetland depression was bare of herbaceous ground cover vegetation, stinging nettle (Urtica dioica) and poison hemlock (Coniuim maculatum) were present. Downed water stained -leaves covered the ground surface.. The upland vegetation surrounding the wetland was dominated by reed canarygrass and Himalayan blackberry. However, native willows and salmonberry (Rubus spectablis) were also present. Although Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment hydrophytic vegetation was dominant at upland sample plots, non-hydrophytic weedy herbaceous plants, such as thistle (Cirsium sp.) and common tansy were also present in upland areas. 4-4 Soils. The soil survey for the area shows well drained Newberg silt loams within this portion of the study area (Appendix F). The surface layer of the Newberg soil is described as very dark grayish -brown silt loam and very fine sandy loam about 20 inches thick. The subsoil consists of stratified very fine sandy loam, loamy very fine sand, loamy sand and silt loam. Inclusions of somewhat poorly drained and poorly drained soils, such as the Woodinville and Puget soil units may be present. The soils observed at sample plots in the vicinity of Wetland 1 resemble those described and mapped for this map unit. At wetland sample plots (S5 and S35) located within the northern and southern portions the wetland, very dark grayish brown silt loams displaying hydric characteristic of low matrix chromas (10 YR 3/2) and yellowish brown (10 YR 4/6, 10 YR 5/6) mottles were observed at depths below 7 inches. At upland sample plots (S34 and S36) located to the east and south of Wetland 1, non -hydric very dark brown (10 YR 2/2) friable silt loams without mottles were observed. At the upland sample plot (S4) located west of Wetland 1, non -mottled dark grayish brown (10 YR 4/2) sandy silt loams were observed overlying non -hydric dark brown (7.5 YR 3/2) silty loam subsoils. A 1 -inch band of brown (10 YR 4/2) silt loam was observed at a depth of 10 inches within this plot, indicating that disturbances to the soil profile, such as those associated with installation of the fiber optic cable, have likely occurred in the past. Hydrology. The soils observed within the wetland sample plots (S5 and S35) were not saturated at the time of the site investigation. Wetland hydrology was inferred from secondary indicators, including evidence of a drainage pattern associated with the wetland's depressional geomorphic position within the landscape and the presence of water -stained leaves. It is likely that the wetland is saturated/inundated seasonally during the early portion of the growing season. 4.1.2.2 Wetland 2 Wetland 2 is a PSS wetland that is approximately 83,000 square feet (1.9 acres) in size (Figures 4-4 and 4- 5). It is separated from Wetland 1 to the north by an upland area, and extends approximately 1,400 feet south to PSE Tower 3/9. The wetland is a closed, depressional wetland that is seasonally saturated/inundated. An upland berm associated with a fiber optic cable crosses the wetland, although it was not delineated separately from the wetland unit. The wetland was categorized as a Category III wetland, receiving a score of 42 points on the rating form (Appendix E). Vegetation. Dense hydrophytic shrubs including native Pacific, Sitka and Scouler's willows, salmonberry, and redosier dogwood are the dominant canopy species within the PSS wetland. Reed canarygrass is the dominant herbaceous species, although portions of the ground surface within the wetland were bare at the time of the surveys, and covered with downed water -stained leaves. The vegetation observed at adjacent upland sample plots was also predominately hydropohytic, with red elderberry (Sambucus racemosa) and Himalayan blackberry also represented. Mixed grasses and weedy species were present along the edge of the trail, including red fescue (Festuca rubra), annual bluegrass (Poa annua), creeping buttercup (Ranunculus repens), stinging nettle, and narrow -leaved plantain (Plantago lanceolate). This area appears to be mowed on a regular basis. The PEM component of the wetland is approximately 2,900 square feet (0.07 acres) in size (Figure 4-5). The dominant plant species include common cattail (Typha latifolia) and swamp smartweed (Polygonum hydropiperoides). Duckweed (Lemma minor) was observed floating on the water surface during surveys. The indicator status for each of these plant species is obligate. Soils. The soils mapped within this portion of the study area are hydric Puget silt loams. Puget silt loams predominantly consist of mottled dark grayish brown and grayish brown silly clay loam to a depth of about Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 45 inches. The substratum is gray silty clay. The soils observed at sample plots investigated within the vicinity of Wetland 2 resembled those described for the Puget soil unit. 4-5 At wetland sample plots (S6 and S13) located near the northern and southern boundaries of Wetland 3, grayish brown clayey silt loams displaying hydric characteristics of low matrix chromas (10 YR 5/2) with dark yellowish or strong brown (10 YR 4/4, 10 YR 4/6) distinct and/or prominent mottles were observed. At wetland sample plot S9, very dark brown (10 YR 2/2) silt loams with grayish brown (10YR 5/2) and brown (7.5 YR 4/4) depletions and distinct mottles were observed. At the wetland sample plot (S11) located in the PEM portion of the wetland, hydric very dark gray (7.5 YR 3/1) silt loams were observed. At the wetland/upland transition sample plot (S8) located on the westem boundary of the wetland, prominently mottled brown (10 YR 4/2) and dark brown (10 YR 3/3) hydric soils were observed. This plot was mapped as the wetland/upland transition because there was no positive evidence of wetland hydrology. At sample plots (S7, S10, and S12) in upland areas to the north and south of the wetland, soils were brown, dark brown, and very dark grayish brown silt loams. These soils had matrix chromas of 2 or greater (10 YR 4/3, 10 YR 3/3, 10 YR 3/2), and no mottles were observed. Hydrology. Inundated and or saturated surface soils were observed at the wetland sample plots (S6, S11 and S13). No primary or secondary indicators of wetland hydrology were observed within the upland sample plots located upslope of the wetland or in the sample plot (S8) marking the wetland/upland transition. 4.1.2.3 Wetland 3 Wetland 3 is a very small (500 -square -foot [0.01 -acre]), closed depressional PSS wetland that is separated from Wetland 2 to the north and Wetland 4 to the south by upland areas (Figures 4-2 and 4-6). The delineated wetland is considerably smaller than the City's mapping of this wetland. It is a Category III wetland, receiving a score of 35 points on the rating form (Appendix E). Vegetation. The dominant canopy species within the wetland include black cottonwood and Pacific willow. Additional shrub species include redosier dogwood and Himalayan blackberry along the edges. During surveys, downed wood and branches from past tree trimming covered the ground surface to a depth of approximately 6 inches. Portions of the ground surface were bare or covered with downed wood or water - stained leaves. In other areas, reed canarygrass, stinging nettle and slough sedge (Carex obnupta) were present in the herbaceous layer. The vegetation within adjacent upland areas was similar to the vegetation in the wetland, except that Himalayan blackberry was more dominant. Soils. Soils in the vicinity of Wetland 3 are mapped as Puget silty clay loam (Appendix F). At the wetland sample plot (S17) located near the southem end of Wetland 3, very dark gray fine silt loams soils displaying low matrix chromas (10 YR 3/1) were observed. At the wetland sample plot (S15) located near the northern end of the wetland, similar hydric soils with 15 percent gray (10 YR 5/1) depletions/mottles were observed below 4 inches of very dark grayish brown (10 YR 3/2).topsoil. In the upland area to the north of Wetland 3 (sample plot S16), non -hydric mottled brown (10 YR 4/3) gravelly silt loam with a matrix chroma of greater than 2 was observed. In the upland areas to the south of Wetland 3 and north of Wetland 4 (sample plot S14), non -mottled very dark brown and very dark grayish brown (10 YR 2/2, 10 YR 3/2) sandy and silty loams were observed. Hydrology. At the wetland sample plots, soils were saturated to the surface. At wetland sample plot S17, the water table was measured within 1 inch of the surface. At the upland sample plots, no primary or secondary indicators of wetland hydrology were present. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 4.1.2.4 Wetland 4 4-6 Wetland 4 is a closed, depressional PSS/PEM wetland that is approximately 3,300 square feet (0.08 acres) in size (Figure 4-7). It is bounded by the Interurban trail to the west, railroad tracks to the south and east, and upland to the north. The field -delineated wetland is comparable in coverage to wetland mapped by the City in this area (Figure 3-1). Wetland 4 is a Category III wetland, receiving a score of 41 points on the rating form (Appendix E). Vegetation. The western edge of the wetland is dominated by hydrophytic hardhack (Spiraea dogulasii), redosier dogwood and reed canarygrass. PEM components are dominated by reed canarygrass. Although these species are also present in adjacent scrub -shrub upland areas, upland plant communities also include the non-hydropytic species common snowberry (Symphoriocarpos albus) and Himalayan blackberry. Willows are present in the central and eastern portions of the wetland and adjacent upland areas to the north. Soils. Soils in this portion of the Interurban site are mapped as Puget silty clay loam (Appendix F). At one upland sample plot (S18), dark gray hydric soils with low matrix chromas (10 YR 4/1) were observed within the upper 6 inches of the soil profile, and mottled very dark gray (10 YR 3/1) subsoils were observed below 6 inches. At a second wetland sample plot (S20), located near the northern end of the wetland, hydric dark grayish brown silt loams with prominent dark yellowish brown (10 YR 4/6) mottles were observed . At upland sample plots (S19 and S21) to the west and north of Wetland 4, non -hydric brown (10 YR 4/2) and very brown (10 YR 3/2) silt and gravelly loams with no mottles were observed within the upper 16 inches of the soil profiles. At sample plot S19, mottled dark gray (10 YR 4/1) subsoils were observed below 16 inches. Hydrology. Secondary indicators were used to infer wetland hydrology at the wetland sample plots, although inundated/ponded areas were observed in the deeper portions of the wetland. A drainage pattern associated with the depressional wetland topography and water -stained leaf litter in areas of bare ground were noted in portions of the wetland; seasonal inundation was inferred in these areas. No primary or secondary indicators of wetland hydrology were observed at the upland sample plots. 4.1.2.5 Wetland 5 Wetland 5 is a PSS wetland that is approximately 53,200 square feet (1.22 acres) in size. It is situated within a closed topographic depression, bounded by the Interurban Trail to the west and railroad tracks to the east (Figures 4-8 and 4-9). The northern and southern ends of the wetland are bounded by railroad spur crossings. Wetland 5 is a Category III wetland, receiving a score of 42 points on the rating form (Appendix E). The northern portion of Wetland 5 includes the easement area where the City mitigation site is located (Figure 4-8; Appendix B). A narrow strip of gravelly fill that extends east from PSE Tower 4/1 to the railroad tracks bisects the wetland (and the mitigation area); however, the wetland was considered as one unit for the purposes of this delineation. Rock walls reinforce the wetland banks along the edges of the gravel strip and the foundation for PSE Tower 4/1 (see Appendix B for more information). It does not appear that the design of this mitigation site included hydrological connectivity between the two wetland sections under the gravel fill. Vegetation. Within the wetland, the dominant overstory species are the hydrophytic black cottonwood, red alder, Pacific and Scouler's willows, redosier dogwood, and cluster rose (Rosa pisocarpa). During field surveys, the herbaceous layer was generally lacking in areas where the ground surface was bare due to seasonal ponding. Downed cut limbs and other wood remnants from past vegetation maintenance beneath the transmission lines covered the ground surface within the wetland. Reed canarygrass was present along Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 4-7 the outer fringes of the wetland and adjacent upland areas. Himalayan blackberry was dominant in upland areas. Soils. Soils in this portion of the Interurban site are mapped as Puget silty clay loam (Appendix F). Evidence of gravelly fill and other soil disturbance was observed at each of the sample plots within this portion of the study area. At sample plots located within the central and northern portions of wetland 5 (S25 and S26), hydric dark grayish brown (10 YR 4/2) gravelly silt loams with prominent dark yellowish brown mottles (10 YR 4/6) and 30 percent rounded, 1 -inch rocks were observed. At the upland sample plot (S24), located near the central portion of the wetland where its drainage channel narrows substantially, pea-sized gravel was observed within very dark gray (10 YR 3/2), non -mottled soils. With the exception of this narrowing of the wetland, the boundary of the delineated wetland is comparable to that of the wetland mapped by the City in this area (see Figure 3-1). Hydrology. Saturated surface soils were observed at one of the wetland sample plots (S25). Additionally, areas of inundation/ponding were observed to the east of this sample plot within the narrow wetland channel. Secondary indicators were used to infer positive wetland hydrology at the other wetland sample plot (S26), located near the north end of the wetland. Piezometers are present within the eastern wetland channel paralleling the railroad tracks, just north of the gravel strip located near PSE Tower 4/1. At the upland sample plot (S24), no primary or secondary indicators of wetland hydrology were observed. 4.1.2.6 Wetland 6 Wetland 6 is a reed canarygrass-dominated PEM wetland that is approximately 4,300 square feet (0.1 acres) in size. It is a closed depressional, seasonally saturated wetland, located on the west side of the Interurban Trail, immediately north of a railroad spur crossing, as shown in Figure 4-9. The location and size of the delineated wetland are comparable to those of the City -mapped wetland (see Figure 3-1). Wetland 6 is a Category IV wetland, receiving a score of 28 points on the rating form (Appendix E). Vegetation. Vegetation at this wetland consists almost entirely of reed canarygrass. Reed canarygrass is also dominant in the adjacent upland areas. Soils. Based on soil survey mapping, Wetland 6 is situated at the interface of hydric Puget silty clay loams and Woodinville site loams with non -hydric Puyallup fine sandy loams (Appendix F). At the wetland sample plot (S22), mottled hydric silt loams with low matrix chromas (10 YR 4/1) were observed. At the upland sample plot (S23), located upgradient of the wetland's northern end, non -hydric very dark brown (10 YR 3/2) silt loams with no mottles were observed. Hydrology. Saturated soils were observed within 5 inches of the surface at the wetland sample plot (S22). The depth to free water in this plot was measured at 16 inches. Because there was no apparent difference in vegetation between the wetland and adjacent upland areas, the topography grade above the wetland swale was used to define the upland boundary. In the upland plot, soils were non -hydric, and no primary or secondary indicators of wetland hydrology were present. 4.1.2.7 Wetland 7 Wetland 7 is a relatively large PSS/PEM wetland that extends south approximately 2,000 feet from a railroad spur to just north of the 180th Street (Figures 4-10 and 4-11). The wetland is bounded on the east by the Interurban Trail, and on the west by adjacent commercial development. The wetland extends beyond the western edge of the study area, as shown in Figures 4-10 and 4-11, and its complete boundary was not delineated in the field. According to the City's GIS mapping, the full size of this wetland is approximately 104,500 square feet (2.4 acres.) The delineated portion of the wetland within the study area measures approximately 57,000 square feet (1.3 acres). Based on City mapping and aerial photos, the wetland extends west approximately 380 feet from the study area boundary, approximately 700 feet from the Green Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 4-8 River. If City mapping is correct, it is unlikely that there is a hydrologic connection between this wetland and the Green River. No culverts or other pipes connecting Wetland 7 to the Green River appear on City GIS maps. Wetland 7 is a Category III wetland, receiving a score of 42 points on the rating form (Appendix E). During AECOM field surveys, biologists observed a broken, 5 -inch corrugated plastic pipe (CPP) culvert along the wetland's western edge near its north end (Figure 4-10). This culvert does not show up on City storm data. Additionally, A petroleum pipeline is present throughout the majority of the wetland's north -south linear corridor. A City of Renton sewer pipeline is also present along the wetland's western's edge. Within the central portion of the wetland, biologists noted a narrow berm paralleling the eastern wetland edge adjacent to the trail. The berm may be associated with the various pipelines that are present within the site vicinity, or may serve as a modest flood control measure. A perched 12 -inch corrugated metal pipe (CMP) culvert was observed bisecting the berm along the wetland's western edge (Figure 4-10). The expansion of NC Power Systems' facility in 2009 resulted in wetland mitigation at the southern end of Wetland 7 (Figure 4-11). Native vegetation was installed along the wetland's western buffer adjacent to the facility's fence. A stormwater detention pond is present near the northeast corner of the facility (see Appendix C). Old flagging of wetland boundaries was observed in this area. Vegetation. The PSS component of the wetland is dominated by the hydropytic canopy species black cottonwood, red alder, and willows (Pacific, Sitka and Scouler's). Reed canarygrass is dominant within the PEM components at the wetland's northern and southern ends, with vetch (Vicia sp.) and field horsetail also present. These herbaceous species are also dominant in the adjacent upland areas, along with the non- hydrophytic Himalayan blackberry. Cattail, swamp smartweed, and reed canarygrass are dominant in the centrally inundated PEM portions of the wetland. A small infestation of Japanese knotweed was also observed within Wetland 7. Soils. Soils in the vicinity of Wetland 7 are mapped as the Woodinville soil unit (Appendix F). This soil unit is characterized as gray silt loam, silty clay loam, and layers of peaty muck extending to a depth of about 38 inches from the surface. The subsoil consists of green -gray silt loam that extends to a depth of 60 inches or more from the surface. Field observations of gravelly fill and developed, built surfaces indicate that past soil disturbances within this map unit have occurred the study area. At sample plots near the north end of the wetland (S31, S32, and S33), mottled dark yellowish brown (10 YR 4/6) hydric soils were observed below non -mottled top soils. At the wetland sample plot (S31), the depth to hydric subsoils was 4 inches, with mottles increasing in density at 12 inches. At the sample plot marking the upland/wetland transition (S32), as well as the upland sample plot (S33), the depth to hydric subsoils was 10 inches, which is considered borderline hydric. At the representative wetland sample plot near the southern end of the wetland (S30), dark gray (10YR 4/1) hydric soils were observed. At the upland sample plot (S29) near the south end of the wetland, dark grayish brown gravelly loams displaying non -hydric characteristics of matrix chromas equal to 2 (10 YR 4/2), without mottles, were observed. The gravel component, which consisted of rounded 1 -inch rocks, comprised 70 percent of the soil profile at this disturbed and filled portion of the study area. The ground surface immediately downslope (north) of this plot, to the toe of the slope of the wetland, was impenetrable due to a hard pan of chert -like rock or bentonite clay liner. Chunks of this substance were also observed underlying hydric soils at wetland sample plot S30. Hydrology. At the wetland sample plot (S31) in the northern portion of the wetland, saturated soils were present at a depth of 6 inches. Secondary indicators, including the presence of a drainage pattern within the depressional wetland topography and the positive results for the FAC -neutral test, were used to infer positive wetland hydrology at this location. The depth to the free water table at the plot was measured at 16 inches. Inundation of 4 to 8 inches was observed within the central and southern portions of the wetland. At the transitional plot (S32), soils were damp but not saturated. No primary or secondary indicators of wetland Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment hydrology were observed at the disturbed upland plots (833 and S29), located near the northern and southern ends of the wetland. 4.1.2.8 Wetland 8 4-9 Wetland 8 is a 75,800 -square -foot (1.74 -acre) PSS/PEM wetland located east of the Interurban Trail (Figures 4-10 and 4-11). It is a seasonally inundated/saturated wetland that is situated within a depression, bounded by the trail to the west, railroad tracks to the east, a railroad spur to the north, and upland areas associated with the 180th Street overpass to the south (Figures 4-10 and 4-11). Rip -rap lines the wetland's southern edge near its terminus adjacent to the trail. The delineated wetland is comparable to the City's mapping (see Figure 3-1). Wetland 8 is a Category III wetland, receiving a score of 44 points on the rating form (Appendix E). Although a narrow gravel pathway bisects the southern portion of the wetland to allow access from the trail to the railroad tracks to the east (Figure 4-11), the two wetland areas have been described as a single unit in this delineation. During field surveys, biologists noted a 24 -inch CMP culvert under the railroad tracks that was discharging into Wetland 8 directly adjacent to and south of the gravel pathway (Figure 4-11). Vegetation. Within the PSS component, the dominant species include black cottonwood, red alder, willows, redosier dogwood and salmonberry. In the PEM component near the wetland's southern end, reed canarygrass and swamp smartweed are dominant. Himalayan blackberry occurs along the wetland's edges and adjacent upland banks. In upland mowed grassy areas adjacent to the trail, representative species include reed canarygrass, thistle, vetch, and stinging nettle. Soils. Soils within the vicinity of Wetland 8 are mapped as hydric Woodinville soils (Appendix F). At the wetland sample plot (S27) located near the southern end of this wetland, hydric, mottled dark yellowish brown (10 YR 4/2) silt loams with 10 percent rounded rocks, approximately 1 inch in size, were observed. At the wetland sample plot (S38) located near the northern boundary, distinct mottles were present within very dark grayish brown (10 YR 3/2) silt loams. At upland sample plots (S28 and S37) located to the north and south of the wetland (S28 and S37), non - hydric, non -mottled very dark grayish brown (10 YR 3/2) gravelly and silt loams were observed. The gravel component comprised 50 percent of the soil profile at sample plot S28, indicating that soil disturbances and fill have altered the natural soil conditions in the immediate vicinity of the trail. Hydrology. During field surveys, the depths of inundation observed within the central and southern portions of the wetland ranged between 0 and 10 inches. Saturated soil conditions and corresponding water table level were observed at the surface (0 inches) at the southern wetland sample plot (S27), and saturated soils were observed at a depth of 4 inches from the surface at the northern wetland sample plot (S38). The water table was observed at a depth of 12 inches from the surface within the soil profile at this location. No primary or secondary indicators of wetland hydrology were observed at the upland sample plots. 4.2 Comparison Between Field Ratings and City Rating As discussed in Section 2.2.7, the 2010 SAO includes a modification that requires wetlands to be rated in accordance with the Washington State Rating System for Westem Washington. Prior to this modification, the City used its own rating system. Wetlands that have not been rated under the state system are provisionally rated under the old system (City Department of Community Development 2010). Because of the different rating systems used, it is not possible to do a direct comparison between field ratings and City ratings. According to City GIS, all the wetlands along the Interurban Trail are considered as a single wetland complex, classified as Type 1 under the old City rating system. Under the state rating system, the wetlands should be considered as separate units unless there is a level surface water connection (such as a culvert) between them (Hruby 2004). Therefore, all the wetlands were rated separately, with the exception of Wetlands 5 and 8, both of which contain two pieces separated by very thin strips of fill. According to the Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment 4-10 state rating system, Interurban wetlands were rated as Category III wetlands, with the exception of the Category IV Wetland 6. Information from field investigations and other data sources may provide additional information pertinent to wetland rating. Wetland FC has not been previously mapped or rated by the City. Therefore, no comparison is possible. 4.3 Wildlife Observations No listed (threatened or endangered) plant or animal species were observed within the study area during field surveys. Evidence of beaver use was observed within the shoreline area at the Family Fun Center site. Biologists noted distinctive gnaw marks on broken trunks and large stems in this area. An unidentified species of rabbit was observed at several location along Interurban Trail during the field investigation. Bull frogs (Rana catesbeiana) were heard and one unidentified native frog was observed along the upland edge of Wetland 1. It is likely that native chorus frogs (Pseudoacris sp.) and red -legged frogs (Rana aurora) inhabit the study area wetlands and adjacent upland areas. Common passerine birds, including American robins (Turdus migratorius), sparrows, and crows (Corvus brachyrhyncos) utilize the habitat present within the study area. On December 2 at dusk, an identified hawk (Buteo sp.) was observed landing in the willow canopy near the strip of gravelly fill in Wetland 5.

According to TMC 18.45.080, the standard wetland buffers are as follows: • Category I and II wetland:100-foot buffer • Category III wetland : 80 -foot buffer • Category IV wetland: 50 -foot buffer According to these buffer distances, the following buffer widths apply to wetlands in the study area. Table 5-1.

On a case-by-case basis, wetland buffer reductions may be allowed where buffer conditions are currently degraded, provided the remaining buffer is enhanced and the buffer does not contain slopes of 15 percent or greater. Additionally, wetland buffers will be increased when they are determined to be particularly sensitive to disturbance, or the proposed development will create unusually adverse impacts.

Wetlands are PSS, PSS/PEM, and PSS/PFO wetlands ranging in size from 500 square feet (0.01 acres; Wetland 3) to 83,000 square feet (1.9 acres; Wetland 2). Wetlands ranged from Category II to Category IV, as determined by the Washington State Rating System for Westem Washington. Table 6-1 summarizes the size, HGM and Cowardin class, and rating category of each wetland. Table 6-1.

Wetland FC is uniquely characterized as a freshwater -tidally influenced riparian wetland. Because of the wetland's direct hydrological connectively to the Green River, it received a higher rating as a Category II wetland. The wetlands at the Interurban site were classified as moderately functioning Category III wetlands, with the exception of Wetland 6, which is a lower functioning Category IV PEM wetland. In general, the Interurban site wetlands are situated within closed depressions that do not discharge to other wetlands or streams. A portion of Wetland 7, however, extends west beyond the study area towards the Green River. Although not investigated during field surveys, it is possible that this wetland is a depressional outflow wetland. However, the City has not mapped any culverts in the western portion of Wetland 7 that might connect to the Green River. Wetland 8 is a depressional wetland, but it is not necessarily closed because of the large culvert spanning under the adjacent railroad tracks. Tukwila Wetland Delineation Report 60163731 April 2011 AECOM Report Environment 6-2 Although numerous trees are present in the Interurban site wetlands, they were classified as PSS wetlands rather than PFO wetlands. Plant communities in these wetlands have a single canopy layer comprised of dense tall shrubs and small trees, but Tess than 30 percent of this vegetation is greater than 20 feet tall. Although taller growing tree species are present in these wetlands, regular maintenance by PSE to provide a safe clearance between vegetation and overhead transmission lines has prevented these wetlands from succeeding to forested communities. Although downed limbs and wood remnant from the vegetation maintenance activities cover the ground surface, these features were not necessarily considered Targe woody debris components.

Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment Appendix A Wetland Functional Assessment Tukwila Wetland Delineation Report April 2011 60163731 AECOM A.1 Introduction Report Environment A.1.1 Background and Objectives This wetland functional assessment has been prepared for Puget Sound Energy (PSE) to provide a detailed assessment of wetlands delineated along transmission line corridors in the City of Tukwila (City). In late November and early December 2010, wetlands were delineated within a study area consisting of two separate areas, known as the Interurban site and the Family Fun Center site. Information about these wetlands, including maps of their delineated boundaries, is provided in the Tukwila Transmission Line Corridors Wetland Delineation (delineation report; AECOM 2011). These wetlands are likely to be affected by ongoing required vegetation maintenance activities by PSE along its transmission line corridors. The Family Fun Center site is a 1.5 -acre site located adjacent to the Green River in Township 23N, Range 4E, Section 24. The Interurban site is a 1.2 -mile -long corridor that follows the Interurban Trail within Township 23N, Range 4E, Sections 24, 25, and 36. The Family Fun Center site includes a mitigation site constructed in 1998 to mitigate for impacts to the Green River buffer and loss of the 100 - year floodplain associated with nearby development. The Interurban site includes wetlands created in 1994 to mitigate for impacts associated with construction of the Interurban Trail by the City. The objective of this functional assessment is to provide a detailed account of the wetland functions provided by the wetlands within the study area. Under Tukwila Municipal Code 18.45, a functional assessment is a necessary part of the characterization of wetlands required as part of a permit application for proposed impacts in sensitive areas. An understanding of the functions provided by a given wetland is necessary in order to adequately assess how these functions may be impacted by a proposed project. The functional assessment also provides the basis for determining whether proposed mitigation activities will adequately replace the functions that are lost as a result of a given activity. A.1.2 Functional Assessment Methodology The primary source of information for this functional assessment is the completed state rating forms for the study area wetlands, provided in Appendix E of the delineation report. The rating forms ask specific questions about indicators of functions, divided by the three major groups of functions wetlands perform (improving water quality, hydrologic functions, and wildlife habitat; Hruby 2004). Therefore, it provides a good overview of wetland functions. Additionally, cultural and socioeconomic functions were assessed using the Wetland and Buffer Functions and Semi -Quantitative Performance Assessment (Cooke et al. 2000). Finally, wetland functions of wetlands at the Interurban site were characterized using the Washington Department of Transportation's (WSDOT's) Wetland Functions Characterization Tool for Linear Projects (Null et al. 2000). This functional assessment tool was utilized because of the linear nature of wetlands located along the Interurban Trail. This tool was not applicable for Wetland FC at the Family Fun Center site, because this wetland is not linear and only intersects a small portion of the transmission line corridor in the area. Tukwila Wetland Delineation Report April 2011 60163731 A-1 AECOM Report Environment A.2 Categorical Ratings and Functional Assessment (Western Washington Rating System) A.2.1 Overview In the Washington State Wetlands Rating System for Western Washington (Hruby 2004), three wetland function groups are assessed: water quality, hydrologic functions, and habitat. Based on best available science, the rating system considers that a wetland's ability to provide certain levels of water quality and hydrologic functions is specific to its hydrogeomorphic (HGM) classification. In the case of Wetland FC at the Family Fun Center site, the HGM classification is riverine — freshwater tidal wetland. In the case of the Interurban site wetlands, the HGM classification is depressional wetlands. Rating forms specific to these HGM wetland classes were used to evaluate water quality and hydrologic functions for the wetlands in the study area. Other, non -applicable rating forms (i.e., for slope and lake -fringe wetlands) were excluded. Evaluations of habitat are not specific to HGM classification; all wetlands in the study area were rated according to the same habitat criteria and rating forms. Completed rating forms for the study area wetlands can be found in Appendix E of the delineation report. Table A-1 summarizes the overall categorical rating and wetland function group scores assessed for each of the wetlands in the study area. Wetlands receiving high rating scores of equal to or greater than 70 points are classified as Category I wetlands. Wetlands receiving relatively high to moderate scores of 69 to 50 points are classified as Category II wetlands. Wetlands receiving scores between 30 and 50 points are ranked as Category III wetlands, and wetlands receiving low scores of less than 29 points are Category IV wetlands. The maximum score that can be earned by depressional and riparian HGM class wetlands performing at the highest level in all functional categories is 100 points. The maximum scores that can be earned by HGM class riverine and depressional wetlands in the wetland function groups water quality, hydrologic functions, and habitat are 32, 32 and 36 points respectively. Table A-1.

Interurban Wetlands 1,2, 3, 4, 5, 7 and 8 are classified as Category III wetlands. Wetland 6 at the Interurban site received the lowest rating, Category IV, with a score of 28 points. Wetland FC at the Family Fun Center site received the highest rating score (53 points) of all the project wetlands, and is classified as a Category II wetland. To qualitatively describe the quantified level of functions being served by the project area wetlands, designations of "low", "medium", and "high" are used. AECOM has assigned these descriptors based on points received by each wetland on the rating form in relation to the maximum potential scores for each wetland function group. The three qualitative descriptors correspond to three equally distributed ranges of points. For the water quality and hydrologic categories, scores of 0 to 11 points indicate that functions are being served at low levels, and scores of 12 to 31 points indicate that functions are being served at moderate levels. For the habitat category, Scores of 0 to 12 points indicate low levels of functions, scores of 13 to 24 points indicate moderate levels of functions, and scores of 25 points or greater indicate high levels of wetland habitat functions. Table A-2 lists the study area wetlands in relation to their qualitative descriptors. Table A-2. Qualitative Wetland Functional Ratings Wetlands Qualitative Wetland Functional Group Ratings Cowardin Class' Water Quality Hydrologic Habitat Total Overall Qualitative Functional Rating FC PFO/PSS Moderate Moderate Moderate Moderate 1 PSS High Low Low Moderate 2 PSS/PEM 3 PSS 4 PSS/PEM 5 PSS 6 PEM Moderate Low 7 PSS/PEM High Moderate 8 . PSS/PEM 1Cowardin Classification: PEM =Palustrine Emergent; PSS= Palustrine Scrub -Shrub; and PFO = Palustrine Forested. Using these qualitative descriptors, the Interurban site wetlands, with the exception of Wetland 6, can be described as providing or having the opportunity to provide high levels of water quality functions and low levels of hydrologic functions and habitat. Wetland 6 provides moderate levels of water quality functions, but either lacks the opportunity to provide hydrologic and habitat functions, or provides them at low levels. Although Wetland FC received the highest rating overall, it can be described as providing water quality, hydrologic, and habitat functions at moderate levels. According to rating forms for Wetland FC, the majority of points received can be attributed to habitat features created or enhanced at the site by the mitigation project in this area. Palustrine forested (PFO) wetlands typically provide the highest levels of wetland functions overall. Palustrine emergent (PEM) wetlands typically provide the lowest levels of wetland functions, and Palustrine scrub -shrub (PSS) wetlands generally provide moderate levels of wetland functions. The Cowardin classes for the study area wetlands have been provided in Table A-2 for comparative review. In order to maintain appropriate safe clearances under the PSE transmission lines, trees and tall shrubs growing within the study area wetlands have been topped repeatedly over the years to fairly uniform heights that are typical of describing PSS vegetation communities. Evidence of past topping is most apparent within the City's wetland mitigation easement area (Wetland 5). With the exception of the Tukwila Wetland Delineation Report 60163731 April 2011 AECOM Report Environment Family Fun Center site where a steep gradient allows for taller growing species beneath the transmission lines, representation of PFO wetland vegetation communities in wetland areas is restricted. The high levels of wetland functions that would typically be attributed to forested areas are not available. The following sections provide additional details regarding the functional analysis and rating of the project areas according to the Washington State rating system criteria. A.2.2 Water Quality Functions Base scores for water quality functions are determined based on whether the wetland has the potential to improve water quality. Base scores are then doubled (2x multiplier) if the wetland has the opportunity to improve water quality. With the exception of Wetland FC and Wetland 6, all of the project area wetlands received high scores (22 to 24 points) for water quality functions. Wetland FC and Wetland 6 received moderate scores (12 and 16 points, respectively) for water quality functions. Interurban Site Wetlands. Hydrologically isolated, seasonally ponded wetlands with clay or organic soils and persistent, ungrazed vegetation that also have an opportunity to improve water quality receive the highest points for water quality functions on the rating forms. Given their setting within an urban area, all of the Interurban site wetlands have an opportunity for improving water quality. Therefore, base scores for water quality function were subject to a multiplier of two, thus doubling the total points accrued. The Interurban site wetlands are generally closed depressional or intermittent flowing wetlands with seasonal ponding and persistent, ungrazed vegetation, which corresponds to high water quality scores. However, Wetland 6, the reed canarygrass-dominated PEM wetland, provides moderate levels of water quality functions. Although the dense herbaceous vegetation cover typically associated with PEM wetlands can provide high levels of water quality functions, this function is reduced during the summer months when seasonal inundation and/or saturated conditions are not present and the vegetation becomes dormant. The hydrology within Wetland 6 appears to be restricted to seasonal saturation rather than seasonal inundation/ponding, thus reducing the potential for water quality functions to be served at the highest level. In contrast, the dominant willows and other woody -stemmed vegetation at the other Interurban site wetlands provide year-round infiltration functions. None of the study area wetlands received points for organic and clay soils, which are lacking. Due to potential hydrological connectivity via the City's stormwater system near Strander Blvd, Wetland 1 was considered to have an intermittently flowing outlet. It is also possible that Wetlands land 8 may have intermittently flowing outlets. At Wetland 8 a large culvert was observed that appeared to pass under the adjacent railroad tracks. At Wetland 7, no culverts are mapped by the City, but AECOM biologists did not survey portions of this wetland outside of the study area, and could not confirm that no culvert is present. Wetland FC. Densely vegetated riverine wetlands (trees, shrubs and/ or ungrazed herbaceous plants are present) with surface depressions to trap sediments during a flooding event receive high water quality function scores. In the case of Wetland FC, water quality points are primarily associated with its dense vegetation. Although the wetland is generally a depressional unit within the landscape context, exposed surfaces within the channel and pool area and between the riparian benches appears to be uniformly graded and lacking surface depressions. The 2x multiplier associated with having the opportunity to improve water quality doubled the water quality function score from 6 to 12 points. In addition to the site's urban setting, the wetland is also hydrologically connected to the Green River, a contributing basin where human activities have raised levels of sediment, toxic compounds, or nutrients above water quality standards. Tukwila Wetland Delineation Report April 2011 60163731 A-4 AECOM Report Environment A.2.3 Hydrologic Functions Base scores for hydrologic functions are determined based on whether the wetland has the potential to reduce flooding and stream degradation in the case of depressional wetlands, and to reduce flooding and stream erosion in the case of riverine and freshwater tidal wetlands. Base scores are then doubled (2x multiplier) if the wetland has the opportunity to reduce flooding and erosion. Interurban Site Wetlands. According to the state rating system, ponded closed depressional wetlands situated within basins that are less than 10 times the area of the unit, and that have an opportunity to reduce flooding and erosion, receive the maximum number of points for hydrologic functions. None of the Interurban site wetlands serve in a flood storage or water velocity reduction capacity, nor do they appear to help protect downstrem property and aquatic resources from flooding or excessive and/or erosive flows. Additionally, none of the wetlands are located in the headwater of a river or stream that has flooding problems, nor do they appear to impound surface runoff water that might otherwise flow into a river or stream that has flooding problems. Therefore, they do not have an opportunity to reduce flooding and erosion, and the associated 2x multiplier was not applied when assessing their hydrologic functions. Therefore, the overall rating for these wetlands in terms of ability and potential to provide hydrologic functions is low. The contributing watershed basin associated with the Interurban site wetlands appears to be localized to the project area's depressional topography. Stormwater runoff from adjacent commercial development to the west appears to drain to the west, away from the wetlands situated within the topographic depressions to the east. Flows from areas east of the project area into Wetlands 1-7 are restricted by the adjacent railroad berm, which generally blocks surface water hydrologic connectivity. One exception may be Wetland 8, where a culvert that appears to run beneath the railroad tracks was observed. Additionally, it is not known whether there is any discharge from Wetland 7 into the Green River via one or more unmapped culverts. Compared to the other interurban wetlands, Wetlands 7 and 8 received more points (10 points total) for hydrologic functions, mostly due to their higher levels of ponding. Wetland FC. According to the state rating system, densely vegetated riverine wetlands that have the ability to provide overbank storage and slow down water velocities during floods receive high points for hydrologic function. The wetland's small size (0.23 acres) limits its ability to provide overbank storage, although the wetland received the maximum number of points for characteristics of vegetation that slow down water velocities during floods. The mitigation components of Wetland. FC were implemented to provide side channel fish habitat and increased storage capacity. Thus, the 2x multiplier for the opportunity to reduce flooding and erosion was applied to Wetland FC's base score. Overall, Wetland FC provides a moderate level of hydrologic functions. A.2.4 Habitat Scores for habitat functions are determined based on whether the wetland has the potential to provide habitat for many species, and the opportunity to provide habitat for many species. The potential for a wetland to provide habitat for many species is based on its vegetation structure, hydroperiods, richness of plant species, interspersion of habitats, and other special habitat features, (e.g., large, downed woody debris and snags). The opportunity for a wetland to provide habitat for many species is based on its connectivity to buffers and other habitats within the landscape. In general the Interurban site wetlands received low scores, ranging from 5 to 10 points, for habitat functions. Wetland FC received the habitat score of 23 points, indicating that it provides moderately high habitat functions (a score of 25 points or greater on the data form indicates a high level of habitat functions). Tukwila Wetland Delineation Report April 2011 60163731 A-5 AECOM Report Environment Interurban Site. The Interurban site wetlands are predominantly represented by only one vegetation class: PSS. The additional PEM components present within Wetlands 4, 7, and 8 are relatively small, and interspersion of habitats is low. The Interurban site wetlands generally have two hydroperiods: seasonally flooded or inundated and saturated only. Richness of plant species is moderate (between 5 and 19 species) for all of the Interurban site wetlands with the exception of Wetland 6, which is dominated by reed canarygrass. Several of the Interurban site wetlands received points for special habitat characteristics. Although the cut branches and limbs left in the wetlands from vegetation topping under the transmission lines does not qualify as large woody debris, it does provide some habitat features. Buffers associated with the interurban wetlands are restricted by adjacent commercial development, railroad tracks and the paved Interurban Tail. The Interurban site wetlands received low scores for their buffers and opportunity to provide habitat for many species. In regards to the wetland landscape, there are at least three wetlands within 1/2 mile of each of the project wetlands, but the connections between them are disturbed. Wetland FC. Plant species richness at Wetland FC was rated as moderate (5 to 19 species). Wetland FC scored highly on the state rating forms in terms of its special habitat features. The wetland's overhanging vegetation, large woody debris, and lack of invasive plant cover contributed to its score, as well as the presence of recent beaver activity and thin -stemmed persistent vegetation and branches that are permanently or seasonally inundated to serve as structures for egg -laying by amphibians. The FFC wetland also received 4 points in regards to priority habitats. The wetland is associated with the Green River and it provides instream resources in addition to woody debris. Compared to the restricted buffers associated with the Interurban site wetlands, the buffers of Wetland FC consist of relatively undisturbed vegetation and/or open water for approximately 170 feet along the majority the wetland's circumference. A.2.5 Wetland Ratings Based on Special Characteristics The state rating system was designed to differentiate between wetlands based on their sensitivity to disturbance, their significance, their rarity, our ability to replace them, and the functions they provide (Hruby 2004). The first four criteria in this list are values that are somewhat independent of the functions provided by a wetland. Estuarine wetlands, natural heritage wetlands, bogs, old-growth and mature forested wetlands, wetlands in coastal lagoons, and interdunal wetlands have an importance or value that may supercede their functions (Hruby 2004). The study area wetlands were assessed to determine whether they meet any of the criteria for categorization as special characteristic wetlands. The Interurban site wetlands did not meet any of these criteria. Although Wetland FC has a tidal regime, the freshwater wetland did meet the salinity attribute required for categorization based on special characteristics as an estuarine wetland. A.2.6 Special Protection Wetlands The rating system requires the following four criteria also be evaluated to determine whether a wetland may need additional protection in addition to that recommended for its category: SP1 — Wetland unit has been documented as a habitat for any federally listed threatened or endangered animal or plant species. SP2 — Wetland unit has been documented as a habitat for any state listed threatened or endangered animal or plant species. SP3 — Wetland unit contains individuals of Priority Species listed by the Washington Department of Fish and Wildlife. Tukwila Wetland Delineation Report 60163731 April 2011 A-6 AECOM Report Environment A-7 SP4 - Wetland unit has local significance in addition to its functions. For example the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. The study area wetlands do not meet the first three special protection criteria (SP1 through SP3). Prior to adoption of the City of Tukwila's revision of its SAO in August 2010, the Interurban site wetlands were identified as Class 1 wetlands. City of Tukwila Class 1 wetlands were designated as requiring the highest levels of protection by the City, and would meet the SP4 criteria under the old SAO. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment A-8 A.3 Cultural and Socioeconomic Functions As discussed in Wetland Mitigation in Washington State — Part 1: Agency Policies and Guidance (Washington Department of Ecology, U.S. Army Corps of Engineers, and U.S. Environmental Protection Agency 2006), wetland functions refer to things a wetland does, regardless of whether it is valued by society. A wetland value, or social function, is something that benefits or is worthwhile or desirable to society. Values are difficult to quantify, but in many cases they relate back to the functions that the wetland performs. Study area wetlands are located along the Green River and Interurban trails, and therefore provide recreational and aesthetic value to Tukwila residents and visitors. Additional consideration of the social functions of the study area wetlands is provided in this Chapter. Prior to the state's current wetland rating system, the Wetland and Buffer Functions and Semi - Quantitative Performance Assessment (Cooke, et. al, 2000) was developed. In addition to evaluating wetland functions, such as flood/stormwater control, base flow/groundwater support, erosion/shoreline protection, water quality improvement, natural biological support, and habitat, which are similar to the functions assessed in the state rating system, cultural/socioeconomic functions were also considered. According to the rating system described by Cooke et al., each wetland function is evaluated according to three groups of criteria. Group 1 criteria receive 1 point for each item checked, Group 2 criteria receive 2 points for each item checked and Group 3 criteria receive 3 points for each item checked. The highest score that can be received for socioeconomic functions is 18 points. The study area wetlands were evaluated, using this methodology, for their ability to provide cultural and socioeconomic functions. The results of this evaluation are presented in Table A-3. The Interurban site wetlands received 14 out of 18 possible points, and Wetland FC received 13 out of 18 possible points. Table A-3. Results of Cultural and Socioeconomic Functional Rating Category Interurban Site Wetlands Wetland FC Rating Points Rating Points Educational Opportunities High 3 High 3 Aesthetic Value High 3 High 3 Commercial Fisheries Lacking 1 Moderate 2 Historical or Archaeological Sites Lacking 1 Lacking 1 Passive and Active Recreational Opportunities Many 3 Some 2 Ownership/Public Access Unrestricted Public Access 3 Privately owned, some public access 2 Total Points 14 13 All of the study area wetlands provide high levels of educational opportunities. The Interurban and Green River trails are accessible and readily used by the public, and are high visibility areas for interpretive displays and other educational opportunities. The tall, dense shrubs habitats, open meadow wetlands, and upland areas at both the Interurban and Family Fun Center sites provide high levels of aesthetic value in an urban environment. The enhancement features at the Family Fun Center mitigation site, which include side channel habitat for salmon rearing habitat translate to moderate commercial Tukwila Wetland Delineation Report 60163731 April 2011 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 AECOM Report Environment A-9 (and tribal) fisheries resources at Wetland FC. The Interuban site wetlands lack commercial fisheries, agricultural, or other renewable resources. Given past site disturbances and city infill, the study area wetlands were not considered to be important historical or archeological sites. Wetland FC received fewer points than the Interurban site wetlands in regards to land ownership and public access. Public access and recreational opportunities associated with Wetland FC are limited to the Green River Trail, which is upslope from the wetland along the top of the shoreline bluff. The Interurban site wetlands have unrestricted public access via the immediately adjacent Interurban Trail, and the ability to provide many passive and active recreational opportunities. Tukwila Wetland Delineation Report April 2011 60163731 AECOM Report Environment A.4 Wetland Functions Characterization Tool for Linear Projects A-10 Given the linear nature of the Interurban site wetlands, the Washington State Department of Transportation (WSDOT) Wetland Functions Characterization Tool for Linear Projects was utilized to evaluate the functions provided by the delineated Interurban site wetlands. This WSDOT method was adapted from the Highway Methodology Workbook Supplement for Wetland Functions and Values (Null, et. al, 2000). The tool was developed to assist WDSOT in evaluating wetland functions that are likely to be impacted in linear capacity due to adjacent infrastructure. The tool utilizes a functional assessment based on the following 12 categories of wetland functions: A. Flood Flow Alteration (Storage and Desynchronizaiton) B. Sediment Removal C. Nutrient and Toxicant Removal D. Erosion Control and Shoreline Stabilization E. Production of Organic Matter and its Export F. General Habitat Suitability G. Habitat for Aquatic Invertebrates H. Habitat for Amphibians I. Habitat for Wetland -Associated Mammals J. Habitat for wetland -Associated Birds K. General Fish Habitat L. Native Plant Richness M. Educational or Scientific Value N. Uniqueness and Heritage For each wetland being evaluated a qualitative descriptor "low", "moderate", or "high" was used to describe the level of functions being provided in each of the 12 categories. Table A-4 summarizes the results of the analysis. With the possible exceptions of Wetlands 7 and 8, the closed depressional wetlands along the Interurban Trail generally provide low flood flow alteration and sediment removal functions. Because of seasonal inundation, fine-grained mineral soils, and areal cover of dense herbaceous vegetation present within the majority of the wetlands, nutrient and toxicant removal functions were rated as moderate to high. None of the Interurban site wetlands provide erosion control or shoreline stabilization functions. Although organic matter production occurs, the closed depressional wetlands do not function in the export of organic matter. For wetlands 7 and 8, however, which may have hydrological connectivity to other areas, this function was rated as high. General habitat suitability was rated low for Wetlands 1 through 6 and moderate for Wetlands 7 and 8. Habitat for aquatic invertebrates was generally rated low to moderate, although Wetland 6 did not meet any of the criteria for this function. None of the Interurban site wetlands provide general fish habitat. Given the lack of permanent water within the wetlands, habitat for wetland -associated mammals is not provided. Native plant richness was rated as moderate for Wetlands 2, 4, 7 and 8, which have both PEM and PSS components. Native plant richness was rated low for Wetlands 1, 3, 5, and 6. All of the wetlands were considered to have educational or scientific value given the public access available via the recreational trail. The wetlands do not meet the criteria for uniqueness or heritage classifications. Tukwila Wetland Delineation Report April 2011 .60163731 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 AECOM Report Table A-4.

Of the Interurban site wetlands, all but Wetland 6 provide low hydrologic and habitat functions, and high water quality functions, with a moderate overall functional rating. Wetland 6 has a low overall functional rating. In terms of cultural and socioeconomic functions (wetland values), all of the study area wetlands score highly. Wetland FC has highly rated educational opportunities and aesthetic values; moderately rated commercial fisheries resources, recreational opportunities; and a low rating for historical or archaeological sites. The interurban site wetlands have highly rated educational opportunities, aesthetic value, recreational opportunities, and public access; and a low rating for commercial fisheries and historical or archaeological sites. Based on WSDOT guidelines for rating the functions of linear projects, Wetlands 7 and 8 potentially provide high levels of nutrient and sediment removal functions and moderate levels of functions pertaining to sediment removal; general habitat suitability; habitat for aquatic invertebrates, amphibians, and wetland -associated birds; native plant richness, and educational and scientific value. Wetland 6 provides low levels of functions in all applicable categories. The remaining wetlands (1 through 5) provide low to moderate levels of functions in all applicable categories. The results of this functional assessment provide information on the specific functions and values offered by each of the wetlands in the study area. This information can be used to help determine how proposed vegetation treatments would impact functions at these wetlands, and to prepare a suitable mitigation plan to adequately compensate for any functions that are lost as a result of these activities.

Source: City of Tukwila 2010 Records Search Tukwila Wetland Delineation Report 60163731 April 2011 AECOM Report Environment B-2 City of Tukwila Mitigation Site The City wetland mitigation site includes two locations adjacent to the Interurban Trail (see Figure 4-8 of the main delineation report), directly related to the City's construction of their portion of the Interurban Trail. PSE granted rights to King County across a portion of the PSE property for the purpose of a public recreation trail. King County assigned portions of its rights and obligation to the City. The City constructed a recreational trail on its portion of the rights, which included filling and modifying certain wetlands. To mitigate the wetland impacts associated with the trail construction, the City obtained a separate easement from PSE for mitigation purposes. A copy of the City's design plans associated with this mitigation site has been included at the end of this appendix. Although the City's original planting plan indicates the only willow to be planted was Sitka willow, currently the site predominantly is comprised of Pacific willow, most all of which has been topped. Family Fun Center Mitigation Site The Family Fun Center mitigation site occurs adjacent to the Green River, at the Family Fun Center site. The owners of the Family Fun Center proposed to develop a parcel adjacent to the Green River. The parcel is owned by the Family Fun Center. The development required a shoreline substantial development permit and buffer reduction. In order to offset loss of 100 -year floodplain storage capacity and impacts to the Green River buffer, the Family Fun Center proposed to excavate and then plant a mitigation site that includes a riverbank shelf and off -channel pond. This work required a Nationwide Permit 27 for Aquatic Enhancement Activities from the U.S. Army Corps of Engineers and coordinated with the Washington Department of Fish and Wildlife and the Muckleshoot Indian Tribe Fisheries Division. The Family Fun Center is responsible for maintaining this mitigation site. PSE has property rights across the Family Fun Center in the form of easements from the 1960s, and may need to coordination with the Family Fun Center regarding vegetation maintenance activities along this segment of the PSE alignment. In addition, the area is subject to the Shoreline Management Plan. Design plans associated with this mitigation site have been included at the end of this appendix. NC Power Systems Mitigation Site The NC Power Systems mitigation site is located adjacent to the study area, at the southern end of the Interurban site (see Figure 4-11 of the main delineation report). NC Power Systems proposed to develop a parcel adjacent to a Type 1 (under the previous rating system) wetland (Wetland 7) located on PSE property. The mitigation site includes wetland buffer enhancement and tree replacement. NC Power Systems is responsible for maintaining the mitigation site. Because the mitigation site is outside of the PSE alignment parcel, PSE does not have any vegetation removal constraints pertaining to this site.

NOTES: AECOM Report Environment Appendix E Wetland Rating Forms Tukwila Wetland Delineation Report April 2011 60163731 /lam' Wetland name or number _c Classification of Wetland Units in Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit iiemg 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 (i.e. except during floods)? NO — go to 2 YES — the wetland class is Tidalju If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — freshwater Tidal Fringe . NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine V wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 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. NO — go to 3 YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (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? 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 <3ft diameter and less than 1 foot deep). NO - go to 5 YES — The wetland class is Slope Wetland Rating Form—western Washington 3 version 2 Updated with new WDFW definitions Oct. 2008 August 2004 Wetland name or number 5. Does the e�ftire wetland unit meet all of the following criteria? unit is in a valley, or stream channel, where it gets inundated by overbank ooding from that stream or river he overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. h• NO - go to 6 The wetland class is Riverine \lc)r c- 41 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, ifpresent, 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. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. 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 your wetland. 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 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.

()% -7046 (V"Ivel tulfl \ a 4V-wl v47,,,,1 IA" el,c> Classification of Wetland Units in Western Washington 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 t P wat r levels in the entire unit usually controlled by tides (i.e. except during floods)? YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. roundsurface water runoff are NOT sources of water to the unit. NO go YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) m size; st 30% of the open water area is deeper than 6.6 ft (2 m)? 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? 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 tt diameter and less than 1 foot deep). YES — The wetland class is Slope Wetland Rating Form — western Washington 3 version 2 Updated with new WDFW definitions Oct. 2008 August 2004 Wetland name or number 5. 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is ooding. YES — The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetly NO — go to 7 YES — The wetland class is Depressional 7. Is the entire wetland unit located in a ver}as area with nosdbvi us 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. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. 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 your wetland. 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 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.

If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. Check List for'Wetlands;ThatMay Need Additional Protection ' (in addition to the protection recommended for its category) YES NO SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (T/E species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands (see p. 19 of data form). SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. \/ I` To complete the next part of the data sheet you will need to determine the Hvdrogeomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands.

NOTE: the connections do not have to be relatively undisturbed. Aspen Stands: Pure or mixed stands of aspen greater than 0.4 ha (1 acre). Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and wildlife (full descriptions in WDFW PHS report p. 152). Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock. Old-growth/Mature forests: (Old-growth west of Cascade crest) Stands of at least 2 tree species, forming a multi -layered canopy with occasional small openings; with at least 20 trees/ha (8 trees/acre) > 81 cm (32 in) dbh or > 200 years of age. (Mature forests) Stands with average diameters exceeding 53 cm (21 in) dbh; crown cover may be less that 100%; crown cover may be less that 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: Woodlands 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). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other.

With the expectation that PSE will be submitting a Tong -term vegetation management and mitigation plan, we can cancel the permit as long as you send in a written request to withdraw the permit.

Do you have time this afternoon to discuss our project on the phone with me? We have been doing field investigations to gather information, surveying wetland and other features, taking pictures, and writing reports. I want to give you an overview of that work and discuss with you what the best way is to re -start a City -PSE discussion. All the plants are budding but there are still few leaves, so it is a good time to field check what is out there. Our biologist suggested maybe we deliver the wetland delineation and function/value report to you a week or so prior to sitting down together. I am looking forward to talking with you about this.

I also added our landslide hazard/steep slope shapefile (landslide). All of these areas are considered sensitive areas under our Environmentally Sensitive Areas Ordinance, and so any tree or vegetation removal or other habitat changes within these areas are subject to tree permits and mitigation.

The document describes the current design revisions primarily related to habitat enhancement, flood storage, and riverbank work. I have provided both general comments, and the necessary revisions to the Riverbank Restoration And Habitat Enhancement report. Riverbank Restoration/Enhancement (Wetland Resources, Inc.) Please note the following suggested revisions: 1. Page 1- Sensitive Area Description a. The City does not regulate the Green River through its Sensitive Areas Ordinance. Therefore, the River is not a Type 1 Watercourse but is rated by the State as a Water Type 1 drainage. b. The Shoreline River Environment is a 40 -foot setback zone that only allows for specific structures or uses (TMC 18.44.130). In addition, the setbacks for all shoreline zones extend from the Mean High Water mark defined as the elevation that corresponds with a discharge flow rate of 9,000 cfs (TMC 18.06.570). However, the term OHWM does apply to Army Corps of Engineers and State Fish and Wildlife regulation. Please clarify this difference in the report regarding setbacks for the river. 2. Page 2 - Mitigation Description a. Per the City's code requirements, there are no "sensitive areas" on the site. Perhaps this could be changed to "river habitat areas". 6300 Southcenter Boulevard Suite #100 to Tukwila, Washington 98188 ® (206) 431-3670 * Fax (206) 431-3665 Family Fun Center Shoreline Memo April 29, 1998 Page 2 3. Page 2 - Alternative Process Description a. The project's shoreline design is not a sensitive area mitigation but was initiated as the City's coordination responsibility with other agencies for SEPA review, Army Corps permitting, and the Shoreline Substantial Development Permit. b. There is no clear and specific discussion of project impacts, so the statement of "avoided and minimized to the greatest extent possible" is questionable. Page 3 states that mitigation is for potential loss of habitat; however, the report has noted that there is a lack of existing habitat and the most significant areas of native riparian vegetation will be preserved (Page 2). Please re-evaluate this approach. Flood storage impact is being mitigated but the habitat restoration and enhancement design is based on SEPA review arid shoreline issues relative to Army Corps of Engineers, State Fish & Wildlife, and Muckleshoot Tribal review and permitting. 4. Page 2, 3 - Riverbank Restoration. And Habitat Creation Project Summary a. What is the status of the data for recorded flow elevations? It seems the statement in the 1st paragraph should be updated to indicate how the information will be used in final design? b. Based on the mapping, it appears some willow or dogwood cover could be impacted by the construction of the off -channel pond's outlet area. c. The last paragraph discusses potential impacts. As stated in 3. above, I don't believe the project's habitat enhancement or creation is being required as a result of impacts. There are essentially no impacts to the significant riparian habitat. The recommended buffer widths from Fish & Wildlife are policy related, and on this site they would provide little improvement without some enhancement. 5. Page 3 - Baseline Information For The Project Impact Zone... a. The report states "The objective of the wildlife study was to determine species presence and potential occurrence". There is no background information about species of fish and no list of species observed on the site. These may not be necessary for the study but it is identified as part of the report. b. Page 4 - Most of the northeastern riparian area is not on the site. I measured about 1,130 feet of on- site habitat. c. Page 5 - With the on-site portion of the riparian habitat being over 1,000 feet long, the current condition would not be compromised by it size. d. Page 5 - Of the 25,000 sq. feet of area, the stated 16,000 sq. feet should be changed to 14,000 sq. feet of blackberry? Fait►ily Fun Center Shoreline Memo April 29; 1918-- - Page 3 6. Page 5 - Mitigation Goals and Objectives a. Change 16,0(0 sq. feet to 14,(X)0? Is the 58,600 sq. feet from creating the off -channel pond? Where does this number come from? b. "stream restoration" should probably be riverbank or riparian restoration. 7. Page 7 - Mitigation Condition And Function a. Is 85,000 sq. feet the total area of enhanced riparian habitat that includes the off -channel pond? The increase of 74,600 sq. feet of functional riparian habitat is understood but the 85,000 sq. feet of new buffer is not clearly identified. The City has not required this type of mitigation analysis using area replacement for the Shoreline permits. However, there are enough numbers on different pages that I would recommend that this information be summarized in a table format. b. Please explain the statement about a physical barrier separating the site from the river. The existing blackberry cover appears to be providing a significant level of protection form intrusion. It should be recognized that the new buffer will not provide a "high functional quality" until it is established and maturing. 8. Page 8 - Mitigation Standards a. How was the 62,600 sq. feet of riparian habitat calculated? See 7.a. above. b. Please change the reference of "streambed" for securing the logs to "riverbank" or another tern. c. The GeoEngineers' report specifically recommends the use of conifers for the log structure durability. Also, rip rap is recommended on the shelf and lower bank in the vicinity of the log snag groups. d. Page 10 - The Performance Security may be conditioned by the Public Works Dept. and King County if they assume a maintenance obligation. e. Page 11 - Please remove the reference to "sensitive area impacts" and "as required by the City of Tukwila ". The mitigation work is being done as a result of agency meetings through the SEPA review process and permits related to working in the waters of the State. The City would require some restoration for work occurring in the Shoreline River Environment. Most of the mitigation is caused by the methods chosen to compensate for filling the floodplain areas.

Monitoring report by Wetland Resources Inc. dated September 16, 2003. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 a Phone: 206-431-3670 a Fax: 206-431-3665 .. I. 1'ROIIr',C'l' DI:SCRII''1'I(�N This project involves construction of a 9,700 square feet mixed use retail, office and food service building along with 84 parking stalls on the last parcel of the three parcel development that includes the Family Fun Center and the Comfort Suites Hotel. The project site is situated on the north side of Interstate 405 between Fun Center Way and the Green River in the City of Tukwila. 11. BACKGROUND In 1998, the Family Fun Center applied for and received approval for the development of approximately 14 acres of property. The proposed buildings at that time included a 9,000 square foot restaurant, a 153 room hotel, a 36,300 square foot arcade building and 7 acres of outdoor attractions including miniature golf, bumper boats, batting cages and a go cart track. To accommodate required flood storage capacity a combination of off -channel pond and riverbank cutback with restoration and habitat enhancements were done adjacent to the Green River. Public access was provided by a city trail along the perimeter of the site with connection to a new pedestrian bridge crossing the River. All the work approved under the 1998 permit was completed before the expiration of that permit (five years) except the development of the third parcel with 9,000 sq. ft. restaurant. The proposal has now changed to a 9,700 square feet mixed use retail, office and food service building along with 84 parkingstalls on the last parcel of the three parcel development. A SEPA addendum was adopted for this revision to the original proposal on August 22, 2003. However due to the expiration of the original shoreline permit a new application for shoreline substantial development permit was required. Extensive fish and wildlife habitat enhancements including log snags and native plantings along all three parcels were done as part of the original Family Fun Center development. At that time, applicant had also obtained a Nationwide 27 Wetland and Riparian Restoration and Creation Activities permit from the US Army Corps of Engineers for construction of the bench and pond and a HPA permit from the State Department of Fish and Wildlife for the outfall. Also, Wetland Resources Inc. prepared the riverbank restoration and habitat enhancement plan that included mitigation plan for the reduction of the recommended Washington State Department of Fish and Wildlife's 100 to 150 foot buffer by creation, enhancement and restoration of the riverbank shelf and off channel pond. To evaluate the success of the riverbank restoration and habitat creation project applicant had to submit a monitoring report for the first three growing seasons. A monitoring report prepared by Wetland Resources was submitted as part of this application on September 16, 2003. The general conclusion of the report is that 80% aerial coverage by native vegetation and less than 20% aerial coverage by invasive vegetation shall be achieved by the end of the growing season in 2004. King County Department of Natural Resources has a bond for the bank stabilization work that was done in 1998 and the applicant is working with the Department to release that bond. 2 III. FINDINGS The site is within the jurisdiction of the Tukwila Shoreline Management Program (SMP). This program was adopted in June, 1974 and amended on March 16, 1982. The City's SMP was reviewed and approved by the State Department of Ecology as being consistent with the State Shoreline Management Act, adopted in 1971. All shorelines are designated urban. The Shoreline Master Plan establishes three management zones adjacent to the Green/Duwamish River: River Zone: This zone includes the first 40 feet from the mean high water mark. Low Impact Zone: This zone includes the second 60 feet from the mean high water mark. High Impact Zone: This zone includes the area from 100 feet to 200 feet from the mean high water mark. Following are the relevant review criteria as contained in the Tukwila Shoreline Regulations (Tukwila Municipal Code, Chapter 18.44) as applied by the City of Tukwila. Shoreline Substantial Development Permit (18.44.80) Any substantial development within 200 feet of any shoreline must receive a shoreline substantial development permit prior to issuance of any local permits by the City. The project site is located within 200 feet of the Mean High Water Mark (MHWM) of the Green River and is subject to shoreline substantial development permit. General Shoreline Regulations (18.44.110) 1. The use is in conformance with the regulations of the underlying district The proposed building is a speculative building and the anticipated uses are office, retail and restaurant type of uses.

Box 3755 Seattle, WA 98124-2255 RE: Family Fun Center - Tukwila, Washington Our Job No. 6125 Dear Mr. Kennedy: CML ENGINEERING, LANG PLANNING, SURVEYING, ENVIRONMENTAL SERVICES February 12, 1998 This letter responds to the November 24, 1997, letter from the Muckleshoot Indian Tribe Fisheries Department relative to the bank stabilization improvements proposed as part of the Family Fun Center project. Barghausen Consulting Engineers, Inc., has been and will continue to work with the City of Tukwila and other agencies to address any issues related to the scope of this project. Barghausen Consulting Engineers, Inc., has reviewed the Muckleshoot letter and has revised the preliminary engineering plans to accommodate the concerns as noted, and has incorporated modifications relative to the revised river bank stabilization geotechnical report prepared by GeoEngineers dated January 26, 1998. A copy of the revised preliminary engineering plans and the revised geotechnical report are enclosed for your review. The intent of this letter is to request that the Army Corps of Engineers re -review the proposed development to determine whether the Department of the Army has any further interest or requires any permits for the project based on the modifications made to the plans. The proposed project will provide detention based on the City of Tukwila's requirement for a 100-year/7- day/24-hour storm event. In addition to this detention, flood storage compensation will also be required, since the project will result in filling a portion of the existing flood storage area located on site. To meet this criteria, we have proposed bank excavation and stabilization above the ordinary high water mark within the Green River to compensate for this combined storage. In doing so, we have requested the cooperation of multiple agencies to accomplish this task: Barghausen Consulting Engineers, Inc., has coordinated with Mr. Andy Levesque of King County Surface Water Management to establish the ordinary high water mark, which Mr. Levesque has determined to be elevation 7.8 across the frontage of the site along the Green River. We based our modified design using elevation 8.0 as the bottom of the cut -bank shelf to provide a buffer so as not to extend below the ordinary high water mark. We have been coordinating closely with the City of Tukwila to address any concerns the City has with respect to its overseeing jurisdiction of the project. We have extended bike/pedestrian pathways as requested to provide easy access to the site, and have cooperated with the Tukwila Parks Division to. incorporate a pedestrian bridge over the -Green River; located east -of -the existing -Interurban Avenue arterial bridge. The Muckleshoot Indian tribe has responded with several concerns. They feel that the proposed riparian vegetation removal and bank stabilization may have adverse impacts upon salmon habitat and adult and juvenile salmon in an important part of the Green-Duwamish River basin. In addition to this concern, the Muckleshoot Indian tribe stated in reference to the report by GeoEngineers dated September 26, 1997, that additional bank stabilization required where bank erosion is occurring at the downstream end of the Family Fun Center site is one of the few large, deep holding areas found in the Duwamisb River and the lower Green River for use by upstream migrating adult salmon, particularly Chinook, for holding and resting as 18215 72ND AVENUE SOUTH KENT, WA 98032 (425) 251-6222 (425) 251-8782 FAX Mr. Jack Kennedy Department of the Army Seattle District Corps of Engineers -2- February_- 21998 well as for rearing of juvenile salmon. The Muckleshoot Indian tribe is concerned that the vegetation removal and measures to stabilize this arca as listed in the report by GeoEngineers will adversely impact this area. In response to their concerns, we have modified our design to best accommodate this issue by eliminating the excavation and bank stabilization at this location and retaining the existing trees and vegetation. We have also re -directed the outfall location for the on-site storm drainage system to the west to discharge within the proposed bank cut-back area, avoiding the existing groups of trees that the Muckleshoot Indian tribe has determined protect the salmon habitat and provide a source of food. To enhance upstream migration of salmon, we are proposing to place large woody debris along the river bank below the ordinary high water mark to create a habitat for juvenile salmon. This will be accomplished by placing tree snags buried within the shelf of the bank cut-back area, exposing the root system into the river channel area. These tree snags will be anchored by placing man rocks along the sides to protect them from disturbance. In addition, we are proposing to provide off -channel ponds, which will be located within the shelf portion of the bank cut-back areas, to provide habitat for the juvenile salmon during high flow periods. Family Fun Centers and their consultants involved with this project appreciate the cooperation and comments received from the overseeing jurisdictions, and will continue to make ourselves accessible and will respond to any concerns that other agencies may have. We previously submitted a letter and preliminary design plans to you on August 19, 1997, as a follow-up to a discussion you had with Mr. Dan Balmelli of this office. The letter confirmed your previous determination that the Department of the Army Corps Regulatory Branch would not have any jurisdiction nor require any permits if the excavation and bank stabilization work did not extend below the ordinary high water mark. The stabilization work as proposed with the changes indicated above is still above the ordinary high water mark. We are therefore requesting your confirmation that the proposed work will not require a permit from the Corps. We appreciate your attention in this regard. If you have any questions or comments, please feel free to contact me at this office or respond by correspondence.

The Muckleshoot Indian Tribe Fisheries Division has reviewed these materials and we have some questions and an initial comment: 1. In the materials we reviewed, there is a document entitled "Regulations Governing Tree Trimming Near High -Voltage Power lines". According to this document, there is a North American Electric Reliability Corporation (NERC), a non-governmental regulatory body that issued mandatory standards that govern the height of vegetation growing near certain high-voltage power lines. The applicant, PSE is attempting to comply with these regulations in part per this application. We have several questions regarding these regulations: a. Has FERC, the Federal Regulatory Energy Commission who has oversight to NERC, approved these regulations? b. If FERC approved these regulations, did they undergo Endangered Species Act (ESA) review? If yes, when was this review completed? If no, why not? c. Were these regulations made available for public review prior to the adoption by FERC and NERC? d. Where can one find a copy of the regulations? e. Where is PSE's vegetation management plan that is required by NERC? 2. It appears that some of the trees proposed for thinning may be within the City's wetland mitigation site created for the Interurban Trail project from 1994/1995. If so, how many trees, which species and sizes will be trimmed as part of the project? What is the proposed mitigation for trimming these mitigation trees? 3. Are there any other mitigation projects that may be adversely affected by this project, such as mitigation for the extension of S 180th/SW 43rd and railroad separation project, or Sound Transit's Tukwila Station or other projects in the area? 4. As noted in the cover letter from the applicant dated July 15 2010, the applicant trimmed trees adjacent to the Family Fun Center in 2009. How many trees were trimmed? What species of trees and their diameters were trimmed? Where is the exact location of these trees? file://C:\Temp\XPgrpwise\4C5ACE68tuk-mail6300-po 100168626D 1F377... 05/27/2011 Page 2 of 2 5. For the 102 trees proposed to be trimmed this year, how much trimming besides the number of trees to be trimmed is proposed? It would be useful to know the proposed trees' existing heights and what the proposed tree heights will be, or the existing and remaining crown heights or some quantifiable measure of existing and proposed conditions to determine potential impacts. 6. The applicant's July 15 2010 letter also notes that a separate application will include a mitigation plan that will address this 2010 tree trimming proposal, the 2009 trimmed trees and future tree removal in the corridor. Without more information about impacts and a proposed mitigation plan, it is difficult to assess this project's potential impacts and the adequacy of the proposed mitigation measures. We appreciate the opportunity to review this project and look forward to the City and/or applicant's responses to these questions.

Because of the greater level of detail in this document, please consider it to replace the more general, 11 -page site plan information titled "Vegetation conditions from span 3/5 to 4/5," dated July 6, 2010 and submitted on July 7th. For example, the general site plan indicated that 165 trees would be trimmed this season while the plan submitted herein details that only 102 trees will be trimmed (three of which were trimmed the afternoon of July 7th due to the unusually high temperature that day and the affect it was to have on the sagging of our transmission line wires). To reiterate an important point, no tree removal is included with this request. Proposed tree removal work in this corridor will be the subject of'a separate application to be prepared and submitted later this year. That separate application will include a mitigation plan. That plan will also address any mitigation required for this tree trimming and for tree trimming conducted in 2009 adjacent to the Family Fun Center site. We would appreciate having an opportunity to review and comment on your draft staff report prior to it being officially finalized. The reason for this is our interest in the city approval occurring quickly enough so that the tree trimming can take place prior to more hot weather and noticeable vegetation growth. Resolving an issue such as how much mitigation will be required for tree trimming could delay the approval. While PSE is committed to comply with the final decision on mitigation requirements, we anticipate some time being needed to explore the matter with city staff and clarify the requirements. We appreciate your consideration of this request for review. • • Puget Sound Energy to City of Tukwila July 15, 2010 Page 2 of 2 ENCLOSURES a. Detailed Site Plans (2 copies; PDF file on CD) Tree identification and flagging was done by Arbormetrics and David Evans & Associates field collected the information using Leica ATX1230GG GPS units and prepared the site plans using ArcMap version 9.3 software. b. Data File of Tree Information (2 copies of both worksheet tabs; MS Excel file on CD) This is the same data that is shown on page 13 of 13 of the above Detailed Site Plan. Latitude and longitude data is included from our surveyor's work to facilitate uploading into a city GPS unit so that field auditing could be done easier. On the spreadsheet, the first tab is a summary of trimming and the second tab is all details. c. Example of Willow Tree Stem Clusters & Prior Year Trimming (2 color copies; PDF copies of file on CD) This is a photo of tree #4/2-2, which is recorded as a 28" DBH Pacific Willow. It is difficult to see in the photo, but the tree has one trunk that splits into two large stems within two feet of the ground, one about 14" and the other about 16" DBH. The occurrence of multiple -stems like this is common in this area and makes it difficult to consistently and clearly communicate this information. Also note the woody debris around the base of the tree. Included in the photo is an enlargement of one piece of debris that indicates prior tree trimming cycles. Also included on the CD are the documents provided along with our July 7th submittal (Vicinity and Location Maps.pdf; General Site Plan.pdf; Willow - previously topped.pdf; Willow - previously topped--CLOSE-UP.pdf) Please call me with any questions about this project at (425) 456-2550 or on my cell phone at (206) 790-8153.

Enclosed are the permit application materials for this tree trimming work that we discussed in our meeting last Thursday. No tree removal is included with this request — that removal work will be the subject of a separate application at a later time that will include a mitigation plan. That plan will also address any mitigation required for this tree trimming and for tree trimming conducted in 2009 adjacent to the Family Fun Center site. Please see pages two and three for list of enclosed documents. In last week's meeting, PSE explained the need to trim select trees within the next two to four weeks, to maintain compliance with PSE's vegetation plan which was prepared to meet the NERC reliability standards. The need to trim these trees is driven by the height of individual trees and the amount of wire sag caused by electrical load and air temperature during hot summer weather. Unfortunately for this timing of this tree trimming permit process, record hot weather is upon us and PSE might need to trim some of the trees in the next day or two. As I type this letter, the current weather forecast is for 92 degrees on Thursday, and the current record is 87 degrees. We have verified potential wire sag and are measuring these trees daily. Any trimming of these trees prior to permit issuance will be minimized to only those trees at the highest risk of being too close to the wires. As trees are trimmed, whether before or after the permit is issued, you will be given as -built information to verify trees that were trimmed. Related to this tree trimming"work is an easement that came to my attention late last week. In 1994 Puget Power granted the City of Tukwila an easement to construct a wetland within the company's utility corridor (copy attached #9502150776). It may be that the wetland construction was needed to mitigate for city construction of a portion of the Interurban Trail. The easement grants rights to the city and retains rights for the company. I look forward to working with you and other city staff to clarify this matter. It is worth noting that trees in Puget Sound Energy to 410 of Tukwila Page 2 of 4 • July 7, 2010 the city's easement area have been trimmed in past years to maintain wire clearance, and both re -growth and new growth are planned for trimming this summer.

September 4, 1996 letter from Puget Power to Bob Giberson, City of Tukwila) Background on PSE Vegetation Maintenance Vegetation maintenance is a necessary part of planning overhead utility line construction and conducting subsequent maintenance programs. PSE's vegetation maintenance activities are conducted by evaluating and maintaining utility lines throughout the City of Tukwila on a rotational basis. Routine pruning and tree removal has occurred on the lands associated with our 230 kV system over the last thirty years. Utility vegetation maintenance pruning in the City is proposed under and adjacent to a 230 kV transmission lines and within a wetland and/or wetland buffer. To ensure utility service and safety, vegetation growing under and adjacent to the utility lines must never be allowed to grow high enough to allow an opportunity for the lines to sag into the vegetation and be a threat to life or property, cause an outage or a fire, or damage the utility system. A" Seris%t ve"Area Ordinance Deviation for Buffers TMC18:45:080G"is regnested,1 PSE's 230 kV corridor through Tukwila is primarily owned in fee, with easements across the parcels north of the Family Fun Center north of SW Grady Way and east of Interurban Avenue South. Tree trimming in the vicinity of the Family -Fun Center is not planned this year. Trimming conducted by the Center in 2009 will be recorded by a surveyor, documented in a site plan, and addressed in a mitigation plan that we anticipate submitting later this year. That plan will address mitigation required for the 2009 trimming, the proposed 2010 trimming, and PSE's future plans to remove incompatible trees both within the Interurban corridor and adjacent to the Family Fun Center. Where pruning occurs to protect PSE's transmission system, the work will be performed in a manner that will minimizes even temporary impacts to soil, underlying shrubs, ground cover and other trees. Tree crew staff will be lifted over and into the trimming area by lift bucket trucks — no machinery will leave the Interurban Trail berm adjacent to the wetland area. The method of pruning may include, but is not limited to: 1. Tree limbs will remain on-site and in-place, and will feed the ecosystem and provide habitat. 2. Arboriculturally correct pruning methods will be used to top and side prune trees. 3. Branches will be pruned without damaging the parent stem or branch collar. 4. Cuts will be made to minimize spitting or tearing of the bark. tf Puget Sound Energy to. of Tukwila Page 4 of 4 • July 7, 2010 5. Trees growing along the side and growing into or toward the utility corridor will be pruned by removing the entire branches. Branches that, when cut, will produce sprouts that would grow into the utility space will be removed. Trail Usage along Interurban Corridor PSE expects to keep the trail open to bicycle and pedestrian traffic during tree trimming work. This will be accomplished with the following measures: o Signage will notify traffic they are approaching a work zone o Flaggers will control traffic approaching the work zone o Bucket trucks will park on the easterly shoulder of the trail berm, leaving room for traffic on the westerly portion o Bikers will be asked to walk their bikes past trucks o Warning cones will safely guide traffic around trucks o Traffic will be temporarily stopped for a couple minutes either side of the work zone if hazards are present Please call me with any questions about this project at (425) 456-2550 or on my cell phone at (206) 790-8153.

Specifically,. PSE must perform hotspot trimming on trees (topping, directional pruning or side -pruning) at ten (10) locations along the Interurban Trail. Enclosed is a list of these ten locations, as well as an overall vicinity map, location map, and site map for each of the ten sites. Depending on field conditions, PSE anticipates needing to do this work in the next 2 to 4 weeks. Also enclosed is a photo of a willow tree previously topped by PSE. The photo is provided to show how these species re -grow after being topped. During the last two years, the City of Tukwila and PSE have had several discussions about the company's planned vegetation maintenance work in the city. You have requested information about PSE's vegetation removal plans, mitigation plans and interpretations of NERC regulations. We plan to submit a vegetation maintenance plan for the City of Tukwila's review later this year that will address this. *Unfortunately, we need to conduct this emergency trimming prior to submitting the vegetation maintenance plan to the city. We look forward to meeting you on Thursday to discuss this matter. In addition, if it is useful to you, we are happy to drive the 1.5 mile section of transmission line with you if that would provide greater clarity of our hotspot trimming work.

Environmental Requirements Temporary erosion and sediment control requirements must be identified and appropriate controls installed prior to beginning any vegetation management procedure. Refer to local jurisdiction requirements. Vegetation Management Zones There are three vegetation management zones on transmission rights-of-way. Wire Zone Border Zone Danger Tree Zone The wire zone is located beneath the conductors, and extends a few feet on either side of the conductor. In this zone, all trees maturing at a height of greater than 15 feet shall be removed, unless terrain conditions allow for 40 feet of clearance from the conductors. Vegetation shall not be allowed to encroach within 6.8 feet of any transmission line. The border zone is located along those portions of the right of way not directly under the conductors. In this zone is a diverse plant community of herbaceous and woody plants, including shrubs and small trees. This is accomplished through the selective removal of incompatible trees. In this zone, coniferous trees that can not be pruned for 15 feet of clearance from the conductors shall be removed. Deciduous trces that can not be pruned for 20 feet of clearance from the conductors shall be removed. No vegetation shall be allowed to overhang a transmission conductor. Vegetation shall not be allowed to encroach within 6.8 feet of any transmission line. The danger tree zone is located in the forest cover adjacent to the right of way. The vegetation management objective in this zone is to identify and removed trees that are likely to fall within the next maintenance cycle period (common definition). The key is the identification of trees in the adjacent stand that arc predisposed to falling, thus making them likely to come in contact with the conductors. The goal in the danger tree zone is to maintain reliability over the course of the three year cycle. Clearance Requirements for Existing Construction For existing construction: • Clearing requirements will conform to existing and/or original clearing limits: • All distances are measured from the conductor. Clearing Zone For existing construction, the clearing zone represents a combination of the border and wire zones. ©2007 Puget Sound Energy, Inc.

This fact sheet describes those standards and their impact on tree trimming and removal. Who is NERC? NERC, a non-governmental regulatory body, is an international, independent, self- regulatory, not-for-profit organization. Subject to oversight by the U.S. Federal Energy Regulatory Commission (FERC) and governmental authorities in Canada, NERC's job is to ensure the reliability of the bulk power system in North America. It does this by: Enforcing reliability standards; Assessing reliability annually via 10 -year and seasonal forecasts; Monitoring the bulk power system; Evaluating users, owners and operators for preparedness; and Educating, training and certifying industry personnel. What authority does NERC have? NERC has been appointed as the Electric Reliability Organization (ERO) for North America. NERC has delegated some of that authority to eight regional entities in North America, known as regional reliability organizations, which register and regulate all segments of the electric industry: investor-owned utilities; federal power agencies; rural electric cooperatives; state, municipal and provincial utilities; independent power producers; power marketers; and end-use customers. The regional entity that has jurisdiction over Washington State is the Western Electric Coordinating Council (WECC). NERC has the legal authority to enforce compliance with mandatory reliability standards. NERC achieves compliance through a rigorous program of monitoring, audits and investigations, and the imposition of financial penalties and other enforcement actions for non-compliance as approved by FERC. How does this relate to PSE and the customer and communities PSE serves? NERC's focus is the bulk power system, which includes power generation and the high- voltage transmission of electricity. NERC is not directly involved in the local distribution or delivery of electricity to homes and businesses. But NERC's work to maintain and improve the reliability of the bulk power system impacts the entire electricity industry, because the bulk system forms the backbone of the entire North American network of power delivery lines and equipment. What are the tree removal standards? NERC vegetation standards became effective in June 2007 and require PSE and other utilities to actively manage vegetation in corridors where transmission lines are operated at 200 kV and above. NERC's standards also apply to any lower voltage lines designated by the ERO as being critical to the reliability of the electric system in the region, of which PSE has none. Therefore, PSE's affected transmission lines are those operating at 230 kV. PSE must have a formal vegetation management program for these corridors that includes a schedule for and the type of right-of-way vegetation inspections, as well as identified and documented clearances between vegetation and any July 1, 2010 Jk4)1 n.cf (ern iucf har6. Page 1 of 4 • • REG ULA TIONS GOVERNING TREE TRIMMING NEAR HIGH-VOLTAGE POWER LINES transmission lines, taking into consideration transmission line voltage, conductor sag, and the effects of wind on conductor sway. NERC requires PSE to create a vegetation management plan to achieve minimum reliability. To do that, PSE defined and applies two different clearances, known as Clearance 1 and Clearance 2. Clearance 1 is the clearance that will be obtained at the time of regularly scheduled maintenance, and Clearance 2 is the minimum separation distance that must be maintained at all times between vegetation and the conductors (wires). (The difference between Clearance 1 and 2 is discussed below.) Which PSE transmission lines will these new standards apply? On PSE's system, the vegetation management standards apply to all 324 miles of 230 kV lines in Chelan, Douglas, Grant, King, Kitsap, Kittitas, Pierce, Skagit, Snohomish and Whatcom counties. The standards currently do not apply to our 1,700 plus miles of 115 kV transmission lines or 10,400 plus miles of overhead and 9,800 plus miles of underground distribution lines. Why were the new standards created? The new NERC vegetation standards were created in response to major international and regional power outages within the past several years. In particular, the August 2003 blackout that affected more than 50 million people in the northeastern and midwestern regions of the U.S. and Ontario, Canada, which was later determined to have been caused by a limb that fell on a high-voltage transmission line in Ohio. In early 2006, NERC adopted the new standards to minimize future widespread outages due to vegetation management concerns. How has PSE interpreted these standards? PSE has defined and applies two different clearances known as Clearance 1 and Clearance 2. Clearance 1 (clearance at the time of regularly scheduled maintenance) PSE's defines Clearance 1 by stating that no vegetation with a mature height of more than 15 feet shall be allowed underneath 230 kV conductors. PSE defined Clearance 1 to ensure that the mandatory Clearance 2 could be maintained under all conditions found on PSE's transmission system. Clearance 2 (minimum separation distance at all times) PSE calculates Clearance 2 by applying equipment and terrain conditions specific to PSE's 230 kV transmission system to the existing industry standards for minimum flashover distances on transmission lines. This distance for PSE is 6.8 feet. Any piece of vegetation that gets within 6.8 feet of PSE's 230 kV conductors is in danger of a flashover — electrical current from the transmission line arcing or jumping to the tree causing an interruption or outage — and will put PSE in violation of the NERC standard, which results in significant fines and/or penalties -- $1 million per day per incident. The current National Electric Safety Code standards for designing and building 230 kV transmission lines require a minimum ground clearance (the distance between the lowest point of the line and the ground) of about 22 feet. PSE typically designs for July 1, 2010 Page 2 of 4 • • REGULATIONS GOVERNING TREE TRIMMING NEAR HIGH-VOLTAGE POWER LINES minimum clearances of 25-27 feet, but this is not always possible. To get to the Clearance 2 distance, PSE subtracted the mandatory Clearance 2 distance of 6.8 feet from the minimum ground clearance of 22 feet, and ended up with 15 feet as the maximum height for vegetation underneath the 230 kV conductors. PSE established this clearance as a maximum tree height and not a maintained tree height due to the fast growing trees in the Pacific Northwest. There are many different species that can easily add 8 to 12 feet of new growth in one season, particularly if they have been topped. As an example, PSE generally will not remove a lilac, a tree with a maximum height of eight to 10 feet, which is growing under our 230 kV transmission lines. However, PSE will remove a small cedar tree regardless of its current height, because its maximum height is over 15 feet. What happens if PSE is out of compliance? PSE must document any area that is out of compliance and file a self-report upon discovery of the issue, each time an issue is found. The documentation must include a mitigation plan and timeline to regain compliance. This documentation and implementation represents a significant expenditure of PSE resources and is the primary reason why there are no exceptions to the Clearance 1 rule. If PSE is found out of compliance, PSE could be subject to sanctions and monetary penalties of up to $1 million per day per incident until the vegetation meets compliance standards. If PSE is found out of compliance with documentation and a mitigation plan, PSE will be subject to additional sanctions and monetary penalties. Further, every time a company is found in violation of a standard, its exposure to penalties increases. Are there exceptions to the rule? PSE's vegetation management plan allows one exception to the Clearance 1 rule, which is in areas where terrain conditions allow for more than 30 feet of clearance between vegetation and the lines at maximum operating conditions, larger trees may be allowed to remain in the wire zone. If the transmission line has 60 feet of ground clearance at maximum sag, a tree with a mature height up to 30 feet could remain in the wire zone. There is no exception to the Clearance 2 rule. A Clearance 2 violation would likely result in a fine and possible regulatory action. What methods does PSE use to cut trees? PSE performs tree removal using a variety of different methods and equipment, depending on location. In areas where the trees can be accessed from the road, PSE contractors remove the trees using a standard lift truck and chip truck. PSE contractors will chip and haul away all brush and branches, while leaving it up to the property owner if they want larger pieces of wood to be removed from the property or left for the property owner's use. PSE contractors will be cut stumps as close to ground level as possible. It is important to note that PSE contractors will not completely remove or excavate stumps in stream buffers or wetland areas/buffers. PSE contractors will perform work within wetlands and stream buffers using a climb crew using chainsaws to avoid using heavy equipment or trucks. If a jurisdiction requires PSE July 1, 2010 Page 3 of 4 • • REGULATIONS GOVERNING TREE TRIMMING NEAR HIGH-VOLTAGE POWER LINES to remove the brush and main stem debris from the critical areas, PSE contractors will skid the material out using a piece of machinery operating in wetland or stream buffers. This is not a preferred option, as it results in more ground disturbance than the other methods. Will any vegetation be preserved? PSE will attempt to preserve as much vegetation as possible that has a mature height of 15 feet or less. This type of vegetation often gets knocked down or flattened during the course of the tree removal, but it usually comes back relatively quickly. Low growing species will not be intentionally removed, unless it is determined necessary to provide access for construction crews. Will customers be compensated for their lost trees? The answer to this question depends on the individual situation, including issues such as the nature of the rights PSE possesses. Sometimes PSE may compensate customers and/or jurisdictions with tree replacements. This compensation can come in the form of certificates for shrubs compatible with the transmission line corridor, certificates for trees outside of the transmission line corridor, contributions to the local street tree fund, installation of trees in an off-site location, or a fee in lieu of replacement vegetation. In addition, customers may request PSE to leave the cut timber on their property for personal use or to sell.

Box 393 P.O. Box 90868 Kent, WA 98032 Index, WA 98256 Bellevue, WA 98009 RE: PSE 2008 Maintenance — applications for tree removal , SEPA Environmental Review (E08-005) and Special Permission (L08-018) Dear Brett, Cate, and Kim: In May of 2008,'we sent you a letter of incomplete application for the land use applications identified above. Items that were requested at that time in order for you to have a. complete application included a Shoreline Substantial Development permit application and a $200 outstanding balance for the SEPA application. It was also determined based'on a field visit on May 14, 2008 we needed additional technical information (including a table listing the number, type and species of trees to be removed greater than 4" DBH, identified by parcel number) for our review of the project. We are still awaiting submittal of this information, along with the Shoreline Permit application and remaining balance for the SEPA fee. On August 1, 2008, City staff met with Brett Conrad and Kim Peterson to obtain additional information on PSE vegetation management policies and the work proposed in Tukwila. As a result of this meeting, there are a number of items the City of Tukwila is requesting, in addition to those described in the paragraph above, in order to process your applications: 1. Please provide the height of the transmission lines in the areas where you are proposing to remove trees. This includes the sensitive area locations adjacent to the Green River and within the wetland areas to the south, as well as any areas where trees are proposed to be removed from private property. Parcel lines and property ownership should be indicated on the plans, showing whether the trees are located within PSE right-of-way, easements, or private property. 2. Indicate on plans the extent of the wire zone and the extent of the border zone, and indicate which trees are proposed for removal according to the zone in which they're located. For each tree, indicate species, height, and DBH. 3. Indicate on plans the locations of any trees proposed for removal from the danger tree zone that are also located within sensitive areas (including information on species, height, and DBH). JR Page 1 of2 C:UJocuments and Settings'aimie-R.Desktop1PSE follow up letter 8-7.doc 08/08/2008 9:03 AM. 4. We have reviewed the NERC vegetation standards and do not agree that the extent of vegetation removal as proposed with your applications is required to comply with the NERC standards. The NERC standard requires establishment of vertical clearance between vegetation and transmission wires — not a maximum tree height as PSE has proposed. The NERC standard requires that the vertical clearance take into account local conditions, including line terrain and elevation, species types and growth rates, and an annual vegetation removal plan that considers "all environmental factors" as well as the need to obtain "permissions or permits" from "regulatory authorities" such as the, City of Tukwila. PSE's proposed vegetation removal does not address these issues. Finally, the NERC standard expressly acknowledges the possibility that the transmission owner may be "restricted from obtaining the clearances specified," and directs the transmission owner to develop necessary mitigation measures for when that occurs. We assume that those mitigation measures are contained in PSE's Transmission Vegetation Management Program, which we have repeatedly requested but PSE has declined to provide. We have been able to obtain a copy of the latest version of Seattle City Light's vegetation management policy document regarding their work within 230KV rights-of-way. Rather than. having a maximum vegetation height, SCL's policy specifies that a vertical clearance between the tops of trees and lines, of 12 to 16 feet, must be maintained. They have a four-year maintenance cycle, except for riparian zones and wetlands, where they acknowledge they may have to return every1. to 2 years. Given the foregoing, PSE is not correct that the extreme tree removal that it proposes is required by NERC standards. PSE's proposal must comply with City of Tukwila ordinances and applicable state statutes. 5 We also do not believe that the removal of trees as proposed in your applications meets the requirements of the state Shoreline Management Act and our Sensitive Areas Ordinance. 6. Finally, to help us better understand PSE's policies on vegetation management, we again request that you provide us with a copy of the PSE Transmission Vegetation Management • Program, to include a complete list of compatible trees. If you have any questions as you are compiling this information for our review, feel free to contact me by phone at (206) 431-3659 or by email at jreavis@ci.tukwila.wa.us.

RE: PSE R/W - Tukwila Final Approval of Phase I of the Interurban Trail Wetland Easement and Agreement Dear Don: There were times when I thought these words would never be said but nevertheless...., enclosed is a fully executed Wetland Easement and Agreement ready for recording. Please send me a copy of the document after you have had it recorded. I apologize for taking so long in getting Puget's signatures. At the same time I received the document from you, I also received a complete set of the final construction drawings for phase I of the trail (prior to that all we had for reviewing was preliminary drawings) and since the construction of the wetlands lies within this area I wanted to have internal approval of these final construction drawings, for both the trail and the wetlands, before Puget signed the easement. Also, I was unable to locate any correspondence to the City referring to Puget having the opportunity to review and comment on any drawings and we should have written record to that affect. Likewise prior to construction of phase II, we -will want to review the final set of construction drawings. Therefore, please consider this letter as Puget's acceptance of the proposed work conditioned on the following: • No metallic underground pipes except for drainage and utilities which cross our property at right angles. • Preferably no underground pipes or facilities within 50 feet of any structure, foundation, or anchor. However, any non-metallic pipes which may be within 50 feet shall have their locations well marked and shall be designed for H-20 loading. • No overhead signs, lighting fixtures, or buildings. " No storage of materials or water retention (as opposed to detention). • No landscaping trees with a mature height greater than 15 feet. • Access to Puget's property shall not be impeded. • • Mr. Don Williams December 6, 1994 Page 2 * Metallic fences and gates shall be grounded and these grounds shall also be maintained by the City. * The trail shall be built to accommodate H-20 loading. This is my effort to document what has only been discussed in the past so please forgive me if their is some redundancy.

RECITALS A. Puget Power has an interest in that certain property more particularly described on Exhibit A attached hereto and incorporated herein by this reference (the "Property"), which Property Puget Power uses and intends to continue to use for the transmission and distribution of electric power and other necessary or convenient appurtenances thereto, including, without limitation, fiber optic communication facilities. B. Puget Power previously granted an easement to King County, recorded under King County Auditor's No. 7711100684, as amended by that certain document recorded under King County Auditor's No. 9005240661 (the "Trail Easement"), upon and across a portion of the Property for the purpose of a public recreational trail. C. King County assigned its rights and obligations to that portion of the Trail Easement located within the City's jurisdictional boundaries (the "Tukwila Portion"), and the City assumed such rights and obligations; pursuant to that certain Assignment and Assumption Agreement of even date herewith.. D. The City desires to construct a recreational trail located on the Tukwila Portion, which construction includes filling and modifying certain wetlands. E. Pursuant to various laws, regulations, and ordinances, the City must mitigate the impacts of its proposed wetland filling and modification by providing replacement wetlands. F. The City desires to create a new wetland in accordance with the designs, plans and specifications attached hereto as Exhibit B (the "Wetland") on that portion of the Property more particularly described on Exhibit C-1 and depicted on Exhibit C-2 (both attached hereto and incorporated herein by this reference) (the "Wetland Easement Area") as its mitigation for the wetland filling and modification it will undertake as part of the recreational trail construction on the Tukwila Portion ("Mitigation"). G. Subject to the terms and conditions of this Agreement, Puget Power desires to accommodate the City's need for the Wetland.

Purpose. The City shall have the right to use the Wetland Easement Area for the purpose of developing, constructing, maintaining and repairing the Wetland. Such use of the Wetland Easement Area by the City shall hereinafter be referred to as the "Permitted Use." 2. Manner of Exercising the Permitted Use. 2.1 Except as provided in paragraph 1, the City shall not use, or allow any third party (i.e., a party or entity other than Puget Power) to use, the Wetland Easement Area for any purpose whatsoever. 2.2 The City shall, at all times, cause the Permitted Use to be undertaken in a manner so as to prevent bodily harm to persons (whomsoever) and damage to property (whatsoever). 2.3 Vehicular use of the Wetland Easement Area is prohibited (except for emergency vehicles and such vehicles owned or operated by or on behalf of Puget Power or the City). The City shall use best efforts to ensure that no one (other than the employees, agents, representatives, or contractors of the City or Puget Power) enters upon the Wetland Easement Area. 2.4 The City shall maintain and repair the Wetland Easement Area (and any t`. improvements placed thereon by or on behalf of the City) as necessary to keep the same in a neat, C) clean and safe condition and otherwise suitable for the Permitted Use. In ti -1 2.5 The City shall not cause or permit the development, construction, CI modification, alteration or other change to the Wetland (collectively, "Alteration of Wetland") upon or 0 within the Wetland Easement Area without first obtaining Puget Power's prior written consent (which such consent shall not be unreasonably withheld). Such consent may be conditioned upon Puget Power's review of and satisfaction with detailed plans and specifications, scheduling or such other matters relating to the proposed Alteration of Wetland. Any refusal by Puget Power to consent to any Alteration of Wetland on the grounds that the same may hinder, impair or otherwise interfere with the Puget Power's installation, operation, maintenance, repair, replacement or use of the Property or any facilities used in connection with the transmission or distribution of electric power shall not be deemed unreasonable, as such determinations are reserved to Puget Power's sole judgment and. discretion. If Puget Power shall consent to any one or more Alteration of Wetland, the City shall cause the same to be done in strict accordance with any plans, specifications, scheduling, directions or other conditions of Puget Power's consent. Puget Power's consent to any one or more Alteration of Wetland shall not be deemed to be consent to any other Alteration of Wetland. 2.6 The City shall at all times ensure that the Permitted Use and all activities undertaken in accordance with this Agreement are in compliance with all applicable laws, and the City shall obtain all necessary permits, approvals, or licenses required by any govemmental agency with jurisdiction to undertake any activity on the Wetland Easement Area. 2.7 The City shall not cause or permit any equipment, supplies, vehicles or other items to be kept or stored upon the Wetland Easement Area without first obtaining Puget Power's prior written consent thereto, which such consent shall not be unreasonably withheld. Upon [07772-0701 /BA932210.0261 PAGE 2 10/5/94 12:48 pm • • completion of activities which may disturb the surface or subsurface of the Wetland Easement Area, the City shall restore the Wetland Easement Area to a condition as good or better than the condition the Wetland Easement Area was in prior to such disturbance. If and to the extent the City may cause any excavations within the Wetland Easement Area, such excavations shall be done and completed with the highest degree of care. 950215077E 2.8 The City shall promptly pay, or cause prompt payment to be made to, and secure the discharge of any liens against the Wetland Easement Area asserted by, all persons and entities furnishing any labor, equipment, services, supplies, materials or other items in connection with the Permitted Use. 3. Puget Power's Reserved Rights. 3.1 Puget Power reserves the right to use the Wetland Easement Area, at reasonable times and in a reasonable manner, for any and all purposes not inconsistent with the City's rights hereunder.

Interurban Trail Corridor • Enhancement (On -Site — within PSE easement boundary) through native shrub installations Larger sized shrubs (up to 25' maximum height at maturity) installed within Tower Zones (100' north and south of PSE's 230 kV transmission line towers) and alongside and under the 115 kV transmission line west of Interurban Trail. Representative species for replacement plantings include Sitka and Scouler's willow, vine maple, and beaked hazelnut. Smaller sized shrubs (up to 15' maximum height at maturity) will be installed in remaining areas. Representative species for installation include red -osier dogwood, black twinberry, salmonberry, rose, hardhack, snowberry, red -flowering currant, oceanspray, serviceberry. • Proposed 1:1 Mitigation Ratio based on King County Mitigation Ratios associated with wetland vegetation alterations/conversions. Proposed Enhancement Area (square feet) within wetland and buffers is equivalent to Impacted Area (square feet) based on an estimate of aerial canopy being removed. • Enhance Category IV PEM Wetland 6, west of Interurban trail, to PSS Wetland Class • Retain existing PEM components within site wetlands to preserve diversity of multiple vegetation types • Required replacement plantings exceed tree regulation requirements by a factor of 2 or more. Non-regulated Upland Areas • Apply City's Tree regulations within Tower Zones • Increase requirements of City's Tree regulations by a factor of 2 within other areas Family Fun Center • Enhancement Native Shrub Plantings within altered wetland/buffer areas • Additional Enhancement within Nearby or Adjacent Green River Shoreline Area Remove existing blackberry Install native willows and or other species Option - Educational Signage Table: Summary of Wetlands in the PSE Study Area, Tukwila Transmission Line Corridor Wetland ID Size Hydro- geomorphic Class Cowardin Class' Rating City Regulated Standard Buffer Categoryf Points Family Fun Center Site FC 10,200 square feet (0.23 acres) Freshwater Tidal- Riparian PFO/PSS Category II 55 100' Interurban Site 1 1,100 square feet (0.03 acres) Closed depressional PSS Category III 36 80' 2 83,000 square feet (1.9 acres) PSS/PEM 42 80' 3 500 square feet (0.01 acres) PSS 35 80'. 4 3,300 square feet (0.08 acres) PSS/PEM 41 80' 5 53,200 square feet (1.22 acres) PSS 42 80' 6 4,300 square feet (0.10 acres) PEM Category IV 29 50' 57,000 square feet (1.31 acres) within study area. 2.4+ acres estimated total area Depressional outflow PSS/PEM Category III 42 80' 8 75,800 square feet (1.74 acres) Depressional 44 80' 'Cowardin Classification: PEM = Palustrine Emergent, PSS = Palustnne Scrub -Shrub, and PFO = Palustrine Forested. 2 Wetland Rating System for Westem Washington S b &WA- (6kWa v E Low Trees Shrub Mix Low Trees PSE Interurban Utility Curridor 2010 Vegetation Hotspot Trimming Tree Count by Tower Span and Species July 15, 2010 Page 1 of 1 Area Tower Span Tree Species Quantity *A 3/4 to 3/5 No trimming proposed application #L 10-043 under Area Tower Span Tree Species Quantity **B 3/5 to 3/6 Cottonwood 1 G 4/1 to 4/2 Cottonwood 1 Willow - Pacific 0 -_ Willow - Pacific 13 Willow - Scouler's 0 __ Willow - Scouler's 5 Oregon Ash 0 _- Oregon Ash 0 Black Hawthorne 0 _- Black Hawthorne 0 Area Sub -Total 1• Area Sub -Total C 3/6 to 3/7 Cottonwood 1 H 4/2 to 4/3 Cottonwood 1 Willow - Pacific 0 _- Willow - Pacific 7 Willow - Scouler's 0 _- Willow - Scouler's 3 Oregon Ash 0 _- Oregon Ash 0 Black Hawthorne 0 _- Black Hawthorne 0 Area Sub -Total 1 Area Sub -Total 11 I) 3/7 to 3/8 Cottonwood 0 I 4/3 to 4/4 Cottonwood 0 Willow - Pacific 12 Willow - Pacific 11 Willow - Scouler's 4 -- Willow - Scouler's 3 Oregon Ash 0 _- Oregon Ash 0 Black Hawthorne 1 _- Black Hawthorne 0 Area Sub -Total 17 Area Sub -Total 1' E 3/8 to 3/9 Cottonwood 4 J 4/4 to 4/5 Cottonwood 0 Willow - Pacific 9 Willow - Pacific 9 Willow - Scouler's 2 __ Willow - Scouler's 1 Oregon Ash 0 _- Oregon Ash 1 Black Hawthorne 0 __ Black Hawthorne 0 Area Sub -Total 15 Area Sub -Total 11 F 3/9 to 4/1 Cottonwood 1**K 4/5 to 4/6 Cottonwood 0 Willow - Pacific 7 -- Willow - Pacific 3 Willow - Scouler's 2 _- Willow - Scouler's 0 Oregon Ash 0 __ Oregon Ash 0 Black Hawthorne 0 Black Hawthorne 0 Area Sub -Total 10 - !

Tree Trunks are measured at height of 1.4 meters in the U.S. Project Information: Most of the DBH numbers for willows listed on this page are unusually large for these species. The explanation is that the DBH was a measurement around several stem clusters from a single trunk - they are not single -stem trees. Not uncommon in the project area is for single stems in a cluster to exceed 12" DBH. Project Examples: Shown below are two typical trees within this project area: Scouler's Willow Tree ID #412-8, 28" DBH Pacific Willow PSE Tukwila 2010 Vegetation Hotspot Trimming along the Interurban Utility Corridor DAVID EVANS Job No.: PSEN00000197 Table Page 13of 13 July 15, 2010 This map W£13 created by David Evans and Associates, Inc.

The new standards apply to The new NERC vegetation standards cover transmission lines with voltages of 200 kilovolts (kV) or higher. On our system, the new vegetation management standards will apply to our 327 miles of 230 kV lines in Chelan, Douglas, Grant, King, Kitsap, Kittitas, Pierce, Skagit, Snohomish and Whatcom counties. The standards do not apply to our 115 kV transmission lines or distribution lines. Applying NERC standards to our vegetation management practices surrounding 230 kilovolt transmission lines PUGET SOUND ENERGY The Energy To Do Great Things What are transmission lines? Transmission lines safely transport high voltage electricity from power sources like dams and wind farms to substations in local communities. Transmission normally takes place at voltages of 115 kV and higher. What are distribution lines? Distribution lines are critical links in the electrical system connecting substations and transformers directly to homes or businesses. Unlike transmission lines, distribution lines typically carry less than 69 kV. Distribution lines can be installed both above and below ground.

Box 90868 Bellevue, WA 98009-0868 1.888.225.5773 PAINTED ITA SOY INK Vegetation and reliable power - New tree removal requirements - In response to national and regional power outages within the past several years, the North American Electric Reliability Corporation (NERC), the organization in charge of improving the reliability and security of the bulk power system in North America, has adopted new vegetation management standards for electric transmission lines. The new stan- dards are designed to reduce tree -related transmission system outages. Heat and the elements can cause the lines to sag - so trees not only grow into the lines but the lines sag into the trees causing outages. Problem trees growing under transmission lines Because of these new standards, Puget Sound Energy is changing the way it manages transmission rights of way. Previously, we only pruned tall grow- ing trees within our transmission rights of way, however with the new NERC standards, PSE must remove these tall growing trees. Specifically, we will remove vegetation that matures at a height of more than 15 feet from the areas underneath and beside our transmission rights of way - known as the wire and border zones. Keeping the wire and border zones clear around transmission lines is the most effective way to reduce tree -related power outages. Wire zone The wire zone is the area directly underneath the transmission line, extending for a few feet on either side of the lines. In this area, PSE will remove all vegetation with a mature height of more than 15 feet, regardless of the present size of the vegetation. Border zone The border zone is located along those portions of rights of way not located directly beneath the trans- mission lines. Generally, we remove trees that mature at a height of greater than 15 feet. Some trees with a height of greater than 15 feet may be allowed to remain in the wire zone provided that they can be pruned in a manner that allows sufficient clearance from the lines. Danger tree zone The danger tree zone is located outside of PSE's right of way. PSE will remove any tree that poses a risk ofifalling into the transmission lines.
