Request for sensitive area ordinance deviation to allow a 50% reduction to a Type 1 wetland, tree removal, wetland buffer enhancement and tree replacement. NC Power Systems is proposing to pave approximately 49,000 square feet of a 7 -acre parcel for use as an outdoor storage yard. The project also involves construction of a new stormwater detention pond, and wetland buffer enhancement as mitigation for a request to reduce the required buffer width of a Type 1 wetland by 50 %. The project site is located at 17900 West Valley Highway in Tukwila. SEPA The City of Tukwila issued a Determination of Non - Significance for this project on August 10, 2009. BACKGROUND The proposal is to develop the eastern portion of a 7 -acre parcel with an approximately 49,000 square foot paved area for equipment storage, a new stormwater detention pond, and wetland buffer enhancement. A Type 1 wetland is located offsite, adjacent to the eastern property line of the project site, and has an associated 100 - foot buffer located on the eastern portion of the project parcel. The parcel is already developed on the west side with a commercial/industrial office building, paved surfaces, and a stormwater detention pond. The area where the new equipment storage area and new stormwater detention pond are proposed are located within the 100 -foot buffer of a Type 1 wetland, regulated by Tukwila's sensitive areas ordinance (TMC Chapter 1.8.45). The project area currently has a stormwater pond, a gravel road, a small depression area with an associated wetland, and vegetation including clusters of mature cottonwood and willow trees, grasses, and invasive plants (Reed canary grass and Himilayan blackberry). The wetland buffer width is proposed to be reduced by 50% as part of the project, with the remainder of buffer to be enhanced with native plantings as mitigation for allowing a reduction in buffer width. The new paved area will extend from the area of the parcel that is already developed, all the way to the edge of the reduced wetland buffer. The property owner has applied for a Type 2 Special Permission from the Director to reduce the required wetland buffer width by 50 %; from 100 feet to 50 feet. The small wetland located on the site, as well as the offsite wetland and its 100 foot buffer which extends onto the project site, were delineated by ESA Adolfson and surveyed by AHBL in March 2009. The small, on -site wetland is 380 square feet and isolated, and is therefore not regulated by the City of Tukwila and is proposed to be filled as part of this project. JR Page 1 of 5 09/22/2009 The applicant has also applied for a Tree Clearing Permit in order to remove of all the cottonwood and willow trees on the project site. There are a total of 78 trees to be removed, 18 of which are located within the portion of the wetland buffer that is proposed to be developed. The 18 trees located within the wetland buffer require replacement according to Tukwila's Tree Regulations - Table 1 in TMC 18.54.130 requires that a total of 47 trees replace the 18 trees that will be removed. The replacement trees, including species, size, and spacing within the enhancement area are included in the mitigation plan. There are no trees currently located within the proposed buffer enhancement area located 50 feet to the west of the wetland. DECISION CRITERIA Section 18.45.0908(1) of the Tukwila Municipal Code (TMC) states that "Alterations to wetlands are discouraged and are limited to the minimum necessary for project feasibility." Alteration to wetlands and their buffers is allowed only with permission of the Director, according to the criteria a f under TMC 18.45.090B(1). Additionally, the Director may reduce the standard wetland buffer width on a case -by -case basis, provided the applicant meets criteria outlined in section 18.45.080G of the TMC. Criteria contained in both sections of the TMC are listed in italics below, followed by a discussion of how the proposed project meets each: Section 18.45.090B(1) Alterations: a. The alteration will not adversely affect water quality; Stormwater from new impervious surface created through this project will be collected and treated on site prior to being discharged into the wetland. The area adjacent to the wetland is currently degraded due to the location of a gravel driveway within the buffer, location of equipment stored on pervious surfaces, and the presence of invasive vegetation that consists primarily of Reed canary grass and Himalayan blackberry. The current proposal includes removal of the gravel drive, equipment, and invasive vegetation located within the area 50 feet to the west of the wetland, and enhancement of this area with native plantings. These activities will help to improve water quality from surface flows. b. The alteration will not adversely affect fish, wildlife, or their habitat; The existing condition of the 100 -foot buffer area is degraded, separated from the wetland by an 8 -foot chain link fence, and occupied by a gravel drive and invasive vegetation. The 50 -foot wetland buffer area that will remain as a result of this application, including the area between the edge of the wetland and the chain link fence, will be enhanced through removal of invasive species vegetation and enhancement with native trees, shrubs, and seed mix. Two of the tree trunks from the trees removed for this project will be placed within the buffer enhancement area in order to provide wildlife habitat features. Cut -outs will be made in the bottom of the 8 -foot chain link fence every 50 feet in order to provide wildlife passage from the wetland to the enhancement area. An agreement for maintenance and monitoring shall be executed to provide for survival and/or replacement of any plantings during a 5 -year establishment period. c. The alteration will not have an adverse effect on drainage and/or storm water detention capabilities; This project will increase stormwater generated on -site through construction of approximately 49,000 square feet of impervious surface. Additionally, a small wetland which currently provides storage for runoff and precipitation during storm events is proposed to be filled as part of this project, as it does not meet the criteria for a regulated wetland under TMC 18.06.933 and TMC 08.45.080B. According to the SEPA checklist, the additional stormwater generated from new impervious surface area and the stormwater that is currently stored by the small on -site wetland will be collected through catch basins and piped to treatment and detention facilities on -site, including the existing stormwater detention pond and a new stormwater pond proposed as part of this project. The SEPA checklist states that all storm drainage features will be designed to meet or exceed the requirements of the 1998 King County Surface Water Design Manual. JR Page 2 of 5 14. \Cnerial Penniccinn \NC Machinery \SR 1119_017 1.09_O1R NCPnwer SP &Tree Permits.doc 09/22/2009 d. The alteration will not lead to unstable earth conditions or create an erosion hazard or contribute to scouring actions; The site is flat, with the exception of the stormwater ponds located on the northern portion of the site. Clearing and grading for the project shall follow an approved temporary erosion and sedimentation control (TESC) plan. e. The alteration will not be materially detrimental to any other property; and The work proposed to add an area of outdoor storage requires screening from adjacent properties. The project site is screened on the west side by existing development. Along the north property line in the area where new development is proposed, the property owner will add 10 evergreen trees, spaced 1 tree per 20 lineal feet according to side yard landscape requirements in the C/LI zoning district. One the east side, slats will be added to the existing chain link fence to meet the screening requirements. On the south side, NC Power Systems has applied to the City of Tukwila for a lot consolidation in order to combine the project site with parcel number 3623049059 to the south. NC Power Systems proposes to provide screening at the south side of the lot once the lot consolidation application has been processed. Screening of the south side of the site will be required as a condition of approval of this permit. f The alteration will not have adverse effects on any other sensitive areas. There are no adverse effects anticipated to any other sensitive areas as a result of this application. Section 18.45.080G Variation of Standard Wetland Buffer Width 1) The Director may reduce the standard wetland buffers on a case -by -case basis, provided the reduced buffer area does not contain slopes 15% or greater. The approved buffer width shall not result in greater than a 50% reduction in width. 2) Buffer reduction with enhancement may be allowed by the Director as a Type 2 permit if a. Additional protection to wetlands will be provided through the implementation of a buffer enhancement plan; b. The existing condition of the buffer is degraded; c. Buffer enhancement includes, but is not limited to, the following: 1. Planting vegetation that would increase value for fish and wildlife or improve water quality. 2. Enhancement of wildlife habitat by incorporating structures that are likely to be used by wildlife, including wood duck boxes, bat boxes, snags, root wads /stumps, birdhouses and heron nesting areas; or 3. Removing non - native plant species and noxious weeds from the buffer area and replanting the area subject to 18.45.080. G. 2. c. (1) above. The buffer is currently in a degraded condition due to the location within the buffer of a gravel driveway, storage of equipment, and invasive plants. A buffer enhancement plan has been prepared, which includes removal of invasive plantings including Reed canary grass and Himalayan blackberry. After invasive plants are removed, soil preparation will be done, and the 50 -foot buffer area will be replanted with a total of 240 shrubs, 60 trees, and a native seed mix. Habitat improvements to the area will include the addition of two tree trunks, and the addition of wildlife passages to the existing chain link fence. MITIGATION SEOUENCING The applicant has demonstrated that reasonable efforts were made to follow mitigation sequencing requirements of TMC 18.45.090C. According to the Revised NC Power Sensitive Areas Study and Mitigation Plan, NC Power Systems need for storage area exceeds the square footage available after a 50% reduction in wetland buffer width requested as part of this application. NC Power Systems acquired property to the south (parcel number 3623049059) in order to meet storage area requirements they have in addition to the reduced wetland buffer area included with this request. MITIGATION PLAN TMC 18.45.090 B ALTERATIONS states that a mitigation or enhancement plan must be developed and must comply with the standards of mitigation required in TMC Chapter 18.45. A mitigation plan and performance standards have been prepared by ESA Adolfson for this project. The mitigation plan includes removal of invasive species currently located within the buffer area, soil preparation, and installation of native plantings to include 60 trees and 240 shrubs within the reduced wetland buffer area. Two of the trunks from trees removed as part of the project will be placed within the buffer enhancement area to provide wildlife habitat. The Conceptual Mitigation Plan includes a note that no trees shall be planted, only shrubs, within the 15 -foot utility easement along the eastern property line, and trees shall be planted at least 20 feet away from the sewer line or any utility line. A 10 foot clearance is sufficient to provide clearance from sewer and other utility lines. This change is shown as a redline on the attached set of plans - tree plantings shall only be restricted within 10 feet of utility lines and a condition of approval. As part of the pre - construction meeting, utility lines will need to be located, and the 10 foot distance from the utility lines will need to be flagged and inspected by Tukwila staff. Tukwila staff will also verify that the wetland and the 50 -foot wetland buffer have been flagged in the field as part of the preconstruction meeting. Additionally, performance standards for the buffer mitigation plantings have been developed for the maintenance and monitoring period, and maintenance and monitoring performance security or other assurance device shall be executed as a condition of approval, to provide for survival and/or replacement of any plantings during a 5 -year establishment period. COMMENTS A Notice of Application was mailed on May 22, 2009 to the applicant and to departments and agencies with jurisdiction pursuant to TMC 18.104.090. No comments were received related to this proposal. CONCLUSIONS 1. The proposed use of the site as an outdoor storage yard, stormwater detention facility, and wetland buffer enhancement site are permitted uses in the C /LI zoning district. 2. All trees proposed for removal located within the wetland buffer area will be replaced according to Tukwila's Tree Regulations (TMC Chapter 18.54). 3. The proposed work will not have an adverse impact on water quality. 4. The proposed work will improve wildlife habitat through removal of invasive species within the 50 -foot wetland buffer area, through the addition of wildlife passage cut -outs in the fence to allow access to the buffer enhancement area, and through the addition of the trunks of two trees that will be removed to the buffer area to provide additional habitat features within the buffer enhancement area. Additionally, Best Management Practices will be implemented during construction of the project to minimize potential impacts to fish and wildlife. 5. The proposed work will not have an adverse effect on drainage and/or storm water detention capabilities. All storm drainage features will be designed to meet or exceed the requirements of the 1998 King County Surface Water Design Manual. 6. Clearing and grading for the project will follow an approved temporary erosion and sedimentation (TESC) plan. 7. The proposed work will not be materially detrimental to any other property. JR Page 4 of 5 H: \Special Permission \NC Machinery \SR L09 -017 L09 -018 NCPower_SP &Tree Permits.doc 09/22/2009 IR 8. Water will be discharged to the Type 1 wetland to the east, once stormwater has been detained and treated on- site. Storm drainage features will be designed to meet or exceed the requirements of the 1998 King County Surface Water Design Manual to ensure discharge to the wetland meets federal, state, and local clean water standards. Additionally, buffer enhancement will improve the wildlife habitat and function of the wetland buffer. The proposed work will have no adverse impacts to any other sensitive areas. 9. The proposal meets the criteria for approval of a variation to the standard wetland buffer width: The reduced buffer area does not include slopes greater than 15 %, is currently in a degraded condition, and buffer enhancement is proposed to mitigate for the request for a 50% reduction in buffer width. Buffer enhancement will include removal of non - native plant species and noxious weeks, and the addition of native vegetation and wildlife habitat features. 10. The applicant has demonstrated that reasonable efforts were made to follow mitigation sequencing requirements RECOMMENDATION Staff recommends approval of the Special Permission permit with the following conditions: 1) No equipment shall be used or stored within the 50 -foot wetland buffer enhancement area. 2) The Conceptual Mitigation Plan includes a note that no trees shall be planted, only shrubs, within the 15- foot utility easement along the eastern property line, and trees shall be planted at least 20 feet away from the sewer line or any utility line. A 10 foot clearance is sufficient to provide clearance from sewer and other utility lines. This change will be shown as a redline on plans, and planting of trees shall only be restricted within 10 feet of utility lines as a condition of approval. 3) A pre - construction meeting shall be held prior to the start of work. At this meeting, staff will check to ensure the edge of the wetland, the reduced 50 -foot wetland buffer, the utility lines have been located and flagged, and the 10 -foot buffers from utility lines have been flagged. 4) Screening shall be provided along the south property line prior to final approval, and /or as a condition of approval of the lot consolidation currently under review (Tukwila file number L09 -048). 5) A maintenance and monitoring performance security or other assurance device shall be executed as a condition of approval, to provide for survival and /or replacement of any plantings during a 5 -year establishment period.

The proposed lighting is located within the reduced wetland buffer. The lighting fixtures and related equipment will need to be located entirely outside of the 50 -foot reduced buffer area. Please revise all plan sheets that include the proposed lighting to show that the lights will be located outside of the wetland buffer area. Response: Locations of all lighting and power poles have been revised to be outside of the 50 -foot buffer area. 2. It is not clear how the proposed lighting will be served with electricity. Please revise the plans to show the location of the electrical lines that will be serving these lights. Response: Underground power conduit has been added on C5.1 Utility Plan to show power coming from the existing building to the south. 3. To prepare the enhancement area for plantings, you will need to decompact the soil. Please provide soil prep details and soil amendments on the Mitigation Plan (see mark -ups on attached copy of plan), as well as all construction plan sheets to be used by the contractor for grading and soil preparation. The enhancement area should be tilled to at least 18 inches deep. Our recommendation for soil amendment is to use cedar grove compost or equivalent, to a depth of at least 3 inches, tilled in prior to planting. Response: Soil preparation detail and notes have been added on mitigation plan Fig. 3A and all other construction plan sheets. 4. Please revise the mitigation plan according to the mark -up comments. For easier interpretation of the planting pattern shown in the "Mitigation Area Planting Detail ", provide a guide to the plant abbreviations in the "Buffer Enhancement Schedule ". Response: "Mitigation Area Planting Detail" and "Buffer Enhancement Schedule" is revised to provide guide to plant abbreviation. See revised Mitigation plan. 5. The entire area within 50 feet of the edge of the wetland will need to be enhanced, including the area between the existing fence and the wetland. The Mitigation Plan (Figure 2) will need to be revised to include enhancement in this area. Response: See revised Mitigation Plan. 6. There are several utility lines that run through the wetland buffer enhancement area. Please provide a detailed planting plan that shows where new plantings will be located in relation to these lines (including required perimeter landscaping along the north and south property lines according to the next comment). The planting pattern currently shown on the Mitigation Plan will likely need to be revised in areas where there are utilities. The location of new fence posts will also need to be coordinated with the location of underground utilities. IND Architects, II 1409 Alexande Avenue ( 98424 II Lim 2.53- 922 -4168 II www.hhandj.eom • • Response: Note for trees to stay clear of utility easement is added to Mitigation Plan and other construction plan. 7. The existing fence along the north and south sides of the property in the area that will be improved will need to be relocated in order to meet code requirements related to landscaping, screening, and setbacks. The setback requirement for fences over 6 feet in height in the C /LI zone is 5 feet. Response: See enclosed landscape plan for area along north property line. Screening will be achieved by evergreen trees instead of solid fence. According to TMC section 18.52.040 General Landscape and Screening Requirements (D). "Outdoor storage shall be screened from abutting public and private streets and from adjacent properties. Such screens shall be a minimum of eight feet high and not Tess than 60% of the height of the material stored ". Section F under this section of the TMC states that "All fences shall be placed on the interior side of any required perimeter landscaping." The required landscaping for the side yard in the C /LI zone is 5 feet, consisting of one tree per 20 lineal feet of perimeter, one shrub per 7 lineal feet of perimeter, and living groundcover to cover 90% of the landscape area within three years. Please revise plans and provide fence details to show how these requirements will be met. Landscaping will need to be coordinated with the buffer Mitigation Plan. Response: 5 foot wide strip of land along south property line is left open for now until the lot consolidation for this property and south parcel is approved which will allow the 5 foot strip of land to be paved. There is no required landscaping for the rear property line. However, there is a 5 -foot rear setback requirement. Considering the potential buffer impacts involved in removing the existing fence along the eastern property line, it will be acceptable at this time to leave the existing fence along the eastern property line, as long as cut -outs are provided in the bottom of the fence to provide wildlife passage to the proposed buffer enhancement area. The design of these wildlife passage cut -outs is currently shown on the Mitigation Plan. 8. A bond will be required to assure maintenance and monitoring of the enhanced buffer area. Please provide a cost estimate for 5 years of maintenance and monitoring of the 50- foot wide enhanced wetland buffer area. Response: We estimate the cost for 5 years of maintenance and monitoring to be $15,000.00 (Average $3,000.00 a year). 9. Consider use of some of the removed tree trunks as wildlife habitat features in the buffer area. Response: This has been incorporated into the revised mitigation plan. Please let me know if you have any questions. Sincerely, Chee N. Tung Architect CREATE 1 DESIGN 1 BUILD ESA. dollf on September 4, 2009 John Storm NC Power Systems 17900 West Valley Highway Tukwila, WA 98188 5309 Shilshole Avenue NW Suite 200 Seattle, WA 98107 206.789.9658 phone 206.789.9684 fax www.adolfson.com Subject: NC Power Systems Sensitive Areas Study and Mitigation Plan (Revision 2), Tukwila, WA Dear John: ESA Adolfson is pleased to present the results of a sensitive area study and mitigation plan for the NC Power Systems site, located at 17900 West Valley Highway in the City of Tukwila, Washington (Figure 1). The site consists of a 7.0 -acre parcel (King County Parcel 3623049011), developed with a commercial /industrial office building and paved surfaces on the western and central portions of the property. The area of focus for this investigation was the undeveloped eastern portion of the property. NC Power Systems (the applicant) is proposing an expansion of asphalt and concrete surfaces on the undeveloped portion of the property south of an existing stormwater detention pond at the current facility. A new stormwater detention pond for the new paved area is proposed to the west of the existing pond as part of this project. Parking areas on -site are inadequate for current and projected operations and pose a safety risk to workers moving equipment. ESA Adolfson conducted a wetland and tree study and prepared this sensitive areas study and mitigation plan in support of this development. Findings included in this letter are based on regulatory requirements presented in the Tukwila Municipal Code (TMC)— Chapter 18.45 Environmentally Sensitive Areas and Chapter 18.54, Tree Regulations, a review of existing information, and several site visits conducted from March 4th through 12`h, 2009. Document Review A review of existing literature, maps, and other materials was conducted to identify wetlands or site characteristics indicative of wetlands on the subject property. These sources can only indicate the likelihood of the presence of wetlands; actual wetland determinations must be based upon data obtained from field investigations. Documents reviewed include: • City of Tukwila Wetland Inventory (City of Tukwila GIS, 2006) • King County Soil Survey (NRCS, 2006) • Aerial Photography (USGS, 1990, 2002) • Priority Habitats and Species (PHS) Data (WDFW, 2008) The site is located in the Duwamish -Green River Water Resource Inventory Area (WRIA) 9. The Green River is located across West Valley Highway, approximately 150 feet to the west of the property boundary. According to the City of Tukwila Wetland Inventory (City of Tukwila GIS, 2006), no wetlands are mapped on the site; SAAdoIfsi ,r Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 2 however, three linear Type 1 wetlands are mapped to the east of the property, corresponding to ditches adjacent to the Green River Interurban Trail and the rail road. The nearest is mapped adjacent to the property, running north to south near its eastern border. Two soil types are mapped along the eastern portion of the property: Woodinville silt loam and Newberg silt loam. Newberg silt loam is not listed as a hydric soil, although it may have hydric inclusions. Well- drained soils formed in alluvium characterize Newberg soils, which are found in stream valleys. Woodinville silt loam is listed as a hydric soil. Poorly drained soils formed in alluvium, under grasses and sedges, and on stream bottoms characterize Woodinville soils. (NRCS, 2006) A mix of trees and grassy fields cover the eastern portion of the site in aerial photos from 1990 and 2002 (USGS, 2004). The detention pond and gravel drive are visible in the 2002 aerial, but due to poor resolution, are not discernable in the 1990 aerial. The commercial /industrial facility is visible in both aerials. A review of Priority Habitats and Species data did not reveal any priority habitats or species in the project area (WDFW, 2008). The nearest mapped feature is the off -site wetland located directly east of the site. Existing Conditions ESA Adolfson wetland biologist /soil scientist Laura Brock and Certified Arborist Brooke Sullivan conducted a site visit on March 4, 2009. Return visits were made on March 6, 2009 by Laura Brock and senior wetland biologist Michael Muscari, on March 7, 2009 by Laura Brock, and on March 12, 2009 by Laura Brock and Biological Resources Director/Principal Teresa Vanderburg. A mix of trees, composed of black cottonwood (Populus balsamifera) and Pacific willow (Salix lucida), and a grassy field composed of reed canarygrass (Phalaris arundinacea) cover the eastern portion of the property. The site is relatively flat, with the exception of the constructed detention pond, located in the northeastern corner of the property. Drainage features include a ditch along the northern property edge, which flows into the constructed detention pond, and a ditch along the southern property edge, which flows off -site to the east. These drainage features are regularly maintained and mowed. Weather Conditions Storms with periods of intense rain were recorded in the Tukwila area the night prior to and the morning of the initial March 4, 2009 site visit, and on March 8 and 9, 2009. Rainfall totals from the end of February through mid -March were at or near normal levels. Wetland Study During the site investigation, ESA Adolfson identified one small on -site wetland (Wetland A) in the center of the undeveloped portion of the property and an off -site wetland (Wetland B) to the east of the property (Figure 2). Wetlands were delineated using the Western Mountains, Valleys, and Coast Interim Regional Supplement (Army Corps of Engineers, 2008). Wetlands were surveyed professionally by AHBL and with a Trimble GPS ESA Adolf Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 3 unit. Wetlands were rated and buffers determined using the Tukwila Municipal Code (TMC) 18.45.080. A description of delineated wetlands follows: Wetland A Wetland A is an isolated, 380 square foot wetland identified in a topographic low to the south of the gravel drive (Figure 2). According to hydrogeomorphic conditions, the wetland is a depressional wetland. Wetland A is also a palustrine, forested wetland (Cowardin et. al, 1979). Sample Plot 1 -1 characterizes the wetland (Attachment A). Hydrophytic vegetation, consisting of black cottonwood trees with an understory of reed canarygrass, covers Wetland A. ESA Adolfson observed hydric soils in Wetland A, with a gray (10 YR 5/1) silt loam identified in the first four inches. A gray (2.5 Y 5/1) silt loam with strong brown (7.5 YR 4/6 and 7.5 YR 4/6) redoximorphic features was observed in the subsoil to a depth of 20 inches. Primary sources of water to the wetland include precipitation and overland surface flow from existing paved surfaces to the west. The wetland is isolated and does not share a surface water connection to Wetland B. Soil saturation and the groundwater table were observed to the surface on the March 4, 2009 site visit. Return site visits on March 6 and 7, 2009 revealed a drop in soil saturation and water table levels, with seepage and the groundwater table observed at eight inches below the soil surface. A return site visit on March 12, 2009 revealed a further drop in soil saturation and water table levels, with saturation and the groundwater table levels observed at 10 inches below the soil surface. Based on site visits conducted in the early growing season, Wetland A appears to sustain water at a frequency and duration sufficient to support wetland hydrologic criteria. Wetland A functions at a low level due to its small size, lack of habitat features, lack of vegetation diversity, presence of invasive species, presence of nearby human activity, and disconnection from nearby wetlands and vegetated buffer corridors. The wetland provides a small amount of storage for runoff and precipitation during storm events, although the nearby detention pond provides much greater potential and opportunity for storage volume. According to TMC 18.45.080.C.3, the threshold for a regulated wetland by the City of Tukwila (City) is 1,000 square feet; therefore, Wetland A does not appear to be regulated by the City and does not have a standard buffer requirement. Because the wetland is isolated, it is not likely regulated by the Corps of Engineers (Corps). Wetland B ESA Adolfson delineated the western edge of the wetland directly adjacent to the east of the property (Wetland B). The off -site wetland is a palustrine emergent and scrub - shrub, linear, ditch -like, depressional wetland running parallel to the Interurban Trail. Areas of open water are interspersed among emergent and scrub -shrub areas along the north section of the wetland. Sample Plot 2 -1 characterizes wetland conditions in Wetland B (Attachment A). The elevation of Wetland B is approximately four to six feet lower than the NC Power Systems eastern property edge, which borders the wetland on its western side, and the Interurban Trail, which borders the wetland on its eastern side (Figure 2). Hydrophytic vegetation including Pacific willow, Sitka willow (Sitka sitchensis), red- • r ESA Ada ifs n Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 4 • osier dogwood (Corpus sericea), and reed canarygrass dominated the wetland. A brown (10 YR 4/2) silt loam was observed in the top four inches. From four to 20 inches, a brown (10 YR 4/2) silt loam with strong brown (7.5 YR 4/6) redoximorphic features was present. Primary water sources to Wetland B include runoff from storm drains, overland flow, and precipitation. A storm drainage pipe delivering water from storm drains along SW 431"d Street empties into the wetland at its southern end. ESA observed soil saturation and a water table to the surface on the March 4, 2009 site visit, with surface water over 12 inches deep was observed within five feet of the sample plot. Return site visits on March 6, 7, and 12, 2009 revealed a drop in the level of standing water present within the wetland interior. Wetland B provides a moderate to high level of functions. The size of the wetland and connection with storm water drains allows it the opportunity and potential to provide flood storage and water quality functions. The presence of standing water, large woody debris, vegetation diversity, and overhanging vegetation over portions of the wetland allow it to provide habitat functions at a moderate level. The presence of invasive species, nearby human activity along the Interurban Trail, and disconnection from nearby wetlands prevents it from functioning at a higher level. The buffer surrounding the wetland is composed of a mix of alders, willows, Himalayan blackberry, and reed canarygrass. The City of Tukwila Wetland Inventory identifies Wetland B as a Type 1 wetland. According to TMC 18.45.080.E.1, the City requires a 100 -foot standard buffer for Type 1 wetlands. The Wetland B buffer extends onto the eastern portion of the NC Power Systems property (Figure 2). Uplands Uplands completely surround Wetland A, separating it from Wetland B. Sample Plots 1 -2, 1 -3, 1 -4, 1 -5, 1 -6, and 2 -2 characterize upland conditions (Attachment A). Upland areas contained a dominance of hydrophytic vegetation, consisting of reed canarygrass, black cottonwoods and Pacific willows. However, upland weeds were interspersed throughout upland areas, including: English plantain (Plantago lanceolata), common plantain ( Plantago major), Himalyan blackberry (Rubus armeniacus), and common tansy (Tanacetum vulgare). Soils varied from non - hydric, with a very dark grayish brown (10 YR 3/2) silt loam with dark brown (10 YR 3/3) redoximorphic features present to a depth of 18 inches, to hydric, with a very dark grayish brown (10 YR 3/2) to gray (2.5 Y 5/1) silt loams with dark yellowish brown (10 YR 4/4) redoximorphic features identified in the first five to eight inches of soil and a gray (2.5 Y 5/1) compacted fine sandy loam with dark yellowish brown (10 YR 4/4) redoximorphic features in the subsoil. Due to heavy rains the night prior to and the morning of the initial March 4, 2009 site visit, Sample Plots 1 -2 and 1 -5 exhibited saturation and a groundwater table present at or within 10 inches of the soil surface. However, wetland hydrology was not observed to be present in upland areas. Temporary water ponding and soil saturation within the upper 10 inches was observed to be short-lived and did not persist over eight days. Return site visits on March 6, 7, and 12, 2009 revealed drops in soil saturation and groundwater table levels. On the March 12, 2009 site visit, no saturation and no groundwater table was observed in Sample Plots 1. -2 and 1 -5. Hydrologic conditions observed in these upland plots are likely due to the presence of the compacted fine sandy loam beneath silt loam in the surface layer, which impedes percolation through the soil profile. High intensity storms and the large amount of runoff generated from existing paved surfaces on -site have the potential to create brief periods of ESA A do If or Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 5 saturation with an associated perched water table. Based on the drainage observed at these plots, these areas do not appear to sustain water at a frequency and duration sufficient to support wetland hydrologic criteria, and therefore, do not appear to meet the jurisdictional definition of a wetland. Tree Study ESA Adolfson wetland biologist /soil scientist Laura Brock and Certified Arborist Brooke Sullivan conducted a tree study on March 4, 2009. Trees within the project area consist of 78 cottonwoods bordering the existing paved area and gravel drive and five Pacific willows present in the central portion of the property (Figure 2). Tree locations and diameters at breast height (DBH) are shown on Figure 2. According to the property owner, limbs from cottonwoods on -site continually break off, posing a safety and property damage risk. Within the 100 -foot standard buffer of Wetland B are 18 cottonwood trees. The diameters of these cottonwoods range from eight to 22 inches (Figure 2). Project Impacts and Regulatory .Implications The proposed project will result in the fill of Wetland A (380 square feet), which is an isolated wetland that is not regulated by the City, and a buffer reduction for Wetland B (Figure 3). According to TMC 18.45.080.G.1, a proposed 50 percent reduction of the standard buffer width may be allowed by the Director on a case by case basis. The 18 cottonwood trees within the outer 50 percent of the Wetland B buffer will also be removed, pending approval of the proposed buffer reduction (Figure 3). Since these cottonwoods are within a sensitive area buffer, they are subject to the City's Tree Regulations (TMC 18.54). To satisfy regulatory requirements of the City, a Type 2 Special Permission Permit for the buffer reduction and a Tree Clearing Permit for cottonwood tree removal within the Wetland B buffer is required. Permit approval and issuance is dependent upon satisfying requirements of the TMC and specific criteria outlined in each permit. A discussion of the proposed mitigation and its fulfillment of buffer reduction and tree removal criteria is included in the next section. Proposed Mitigation Mitigation sequencing has been followed for this project as required by TMC 18.45.090.C. NC Power has investigated expanding operations of the existing facility off -site and recently acquired the property to the south of the project area to facilitate this. Wetland impacts are proposed for Wetland A, a low quality wetland in a disturbed setting, rather than Wetland B, a Type 1 wetland. Mitigation that is proposed will enhance and improve the current functions of the Wetland B buffer and provide better protection for the remaining wetland. Wetland A is an isolated wetland and is not regulated by the City; therefore, no mitigation is required for fill. Alteration of Wetland A will not adversely impact existing functions on -site because the wetland is small, isolated from Wetland B, and is located in a disturbed setting. The stormwater storage function that Wetland A provides will be replaced and improved by a new stormwater detention pond constructed on -site to the west of the existing pond. r FSAAdol #s�n Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 6 To allow for a reduced Wetland B buffer (50 feet), the remaining onsite buffer (11,835 square feet) will be enhanced. Tree replacement for the cottonwoods removed during expansion of the parking area will also be provided as part of the buffer enhancement. Figure 3 shows the proposed mitigation area. Buffer Enhancement and Tree Replacement The reduced 50 foot Wetland B buffer will be enhanced with native tree and shrub plantings and invasive species minimization and removal (Figure 3). Currently, the buffer of Wetland B is degraded and provides little water quality protection or wildlife habitat value for Wetland B. A gravel drive exists within the 100 foot buffer area, and will be removed as part of this enhancement plan. Reed canarygrass and Himalayan blackberry are the predominant existing vegetation; no trees are currently located within the 50 foot buffer that is planned for enhancement. All noxious weeds and non - native, invasive plants will be removed (cleared and grubbed) in the buffer mitigation area prior to planting. Planting a diverse native tree and shrub community will add additional protection to Wetland B, increase wildlife and aquatic habitat, improve water quality, and reduce non - native, invasive plant species; thereby fulfilling the criteria listed in TMC 18.45.080.G.2 and the Type 2 Special Permission Permit. A total of 60 trees and 240 shrubs will be planted for the buffer enhancement project (Figure 3). A total of 47 trees out of the 60 trees planned will be used to satisfy tree replacement requirements. Trees will be planted as close to the wetland as possible while staying outside of the 15 foot utility line easement, to provide the greatest value and protection for Wetland B. Shrubs will be planted closer to the proposed paving area and within the utility line easement. A typical planting plan is shown on Figure 3A. Wildlife passage cutouts (a minimum of one foot high by two feet wide) will be placed every 50 feet along the existing fence at the eastern edge of the mitigation area. Two tree trunks removed during tree clearing will be placed in the buffer enhancement area as wildlife habitat features, as shown on Figures 3 and 3A. Tree replacement ratios given in TMC 18.45.130.3 were used to calculate the number of trees required for mitigation of the 18 cottonwood trees that are to be removed. A total of 47 trees will be planted in the Wetland B buffer to fulfill requirements listed in TMC 18.54.130.3 and the Tree Clearing Permit. Since there are no trees currently within the planned enhancement area, no tree retention, protection, or relocation is proposed. Tree removal will occur in the outer 50 percent of the Wetland B buffer, away from Wetland B and existing shrub vegetation that lines the wetland. Trees to be removed are in an area downslope of the inner 50 percent of the Wetland B buffer; therefore, the risk of erosion and runoff is low. Tree replacement ratios and calculations, planting schedule, and planting details are given in Table 1 and in Figures 3 and 3A.

The wetland buffer currently provides low function due to the lack of vegetation structure and species diversity, and the presence of invasive species. The main project objectives are: • Plant a diverse, native, upland tree and shrub community within the reduced 50 -foot Wetland B buffer, which will include a greater diversity of species than existing conditions and will minimize existing nonnative, invasive species. • Replace trees removed from the standard buffer area in the wetland enhancement area. Performance Standards A set of specific performance standards has been established that corresponds to the stated mitigation goals and objectives. These standards serve as the benchmarks that will be used to evaluate the success of the mitigation project. Following monitoring, a determination can be made as to the need for implementing a contingency plan. The proposed performance standards are as follows: • 100 percent survival of installed shrubs and trees within one year of mitigation installation; • Soil deconsolidated to at least a 12 -inch depth at the time of installation; • 30 percent cover of installed shrubs and trees within two years after mitigation installation, and 80 percent cover within five years; • Less than 10 percent cover of non - native, invasive species (excluding reed canarygrass) within five years of mitigation installation, and less than 20 percent cover of reed canarygrass within five years. Reed canarygrass currently covers almost 100 percent of the buffer area and complete eradication is not feasible within five years. The project will minimize the extent of reed canarygrass in the buffer through annual maintenance activities. Shade created as native plants become established will further reduce the amount of reed canarygrass present. • r ESA AdoOfs i Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 8 Monitoring Plan The main objective for mitigation monitoring is to document the level of success in meeting the performance standards described above. An initial stem count of the installed shrubs and trees will be conducted following construction (an as -built count). Monitoring of mitigation areas will continue for five years post - construction. A qualified biologist or landscape designer will conduct the monitoring. The as -built plan will be used to as the basis for monitoring of plant survival. Monitoring will begin the first full growing season after construction is complete and the plants have been installed. Shrub and tree cover will be evaluated quantitatively and qualitatively one year after construction and each year thereafter for five years. The following information will be recorded during the monitoring site visit: • Survival rates of installed vegetation; • General plant health assessment; • Documentation of the presence of undesirable plants (weedy and /or non - native species) with estimated percent cover; • Photo documentation of site conditions; • Impacts to the wetland buffer from human use (e.g., dumping of debris); and • Signs of wildlife use of the area. Reporting Monitoring reports will be prepared for review and approval by the City of Tukwila. The reports will compare the performance standards described in the final mitigation plan to the field observations, and will recommend species replacements or other maintenance activities, if necessary (see Maintenance section below). Reports will present data collected during the monitoring site visit, and document successes in meeting specific performance standards. Photographs will be included to illustrate and document site conditions. Monitoring reports will be submitted to the City by December of each monitoring year. Maintenance Maintenance of the mitigation area will begin after completion of the project and continue, as needed, for five years. After the initial planting acceptance by the project biologist, the landscaping contractor will be responsible for plant survival for a period of one year. NC Power would provide maintenance, as necessary. Maintenance could include, but may not be limited to: • Watering or providing irrigation during seasonable and unseasonable dry periods or when the soils are unusually dry; • Hand removal of non - native or invasive plant species in the buffer mitigation area as needed; Use of herbicides in the wetland buffer is not allowed, unless reviewed and approved by the City of Tukwila; • Providing soil amendments and /or mulch as needed; • Providing fencing around woody plants to prevent animal damage as necessary; • Providing fencing to prevent vandalism or damage caused by humans; and • Installing supplemental plantings as needed. � � 5 1 ESA Adolfson Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 9 Contingency If any portion of the mitigation is not successful, a contingency plan will be implemented. Such plans are prepared on a case -by -case basis to remedy any aspects of the mitigation that do not meet the performance standards. The plan, if required, would be developed in cooperation with the City. Summary NC Power is proposing expansion of paved surfaces at their current facility, located at 17900 West Valley Highway, in Tukwila, WA. ESA Adolfson performed sensitive area and tree studies and prepared this report to support sensitive areas permitting for the NC Power project. Two wetlands were identified within the project area (Figure 2). A summary of these wetlands is given in Table 2: Table 2.

A buffer reduction of 50 percent is also proposed for the Wetland B buffer, resulting in a 50 -foot reduced buffer width and removal of 18 cottonwood trees. To mitigate for project impacts, NC Power is proposing an 13,177 square foot buffer enhancement and tree replacement area which will improve wildlife habitat, increase vegetation structure and diversity, and provide' additional protection for Wetland B (Figure 3). Mitigation for fill of Wetland A is not required because it is an isolated wetland that is not regulated by the City. • r ESA ,AdoIf s n Revised NC Power Sensitive Areas Study and Mitigation Plan September 4, 2009 Page 10 Limitations • Within the limitations of schedule, budget, and scope -of -work, we warrant that this review was conducted in accordance with generally accepted environmental science practices, including the technical guidelines and criteria in effect at the time this study was performed.

Two copies of the Revised NC Power Systems Sensitive Areas Study and Mitigation Plan, July 29, 2009 and two copies of the revised plan sheets Figure 2 and Figure 3 have been attached for your review. Comment 3: To prepare the enhancement area_for plantings, you will need to decompact the soil. Please provide soil prep details and soil amendments on the Mitigation Plan (see mark -ups on attached copy of plan), as well as all construction plan sheets to be used by the contractor for grading and soil preparation. The enhancement area should be tilled to at least 18 inches deep. Our recommendation for soil amendment is to use cedar grove compost or equivalent, to a depth of at least 3 inches, tilled in prior to planting. Response: Soil prep and amendment details have been added to Figure 3A of the report and Figure 3 of the plan sheets. Comment 4: Please revise the mitigation plan according to the mark -up comments. For easier interpretation of the planting pattern shown in the "Mitigation Area Planting Detail, " provide a guide to the plant abbreviations in the "Buffer Enhancement Schedule." Response: Figure 3 of the report and Figure 2 of the plan sheets have been revised according to the mark -up comments from the City. A plant abbreviation guide has been added to the "Buffer Enhancement Schedule." Comment 5: The entire area within 50 feet of the edge of the wetland will need to be enhanced, including the area between the existing fence and the wetland. The Mitigation Plan (Figure 2) will need to be revised to include enhancement in this area. Response: Figure 3in the report and Figures 2 and 3 of the plan sheets have been revised to include the entire 50 feet of buffer. The quantity of trees and shrubs has also been increased in the report and on the figures to include the additional mitigation area. Comment 6: There are several utility lines that run through the wetland buffer enhancement area. Please provide a detailed planting plan that shows where new plantings will be located in relation to these lines • • (including required perimeter landscaping along the north and south property lines according to Comment 7). The planting pattern currently shown on the Mitigation Plan will likely need to be revised in areas where there are utilities, in order to avoid conflicts between plantings and underground utilities. Response: Figure 3 in the report and Figures 2 and 3 of the plan sheets have been revised to adjust the planting detail and add a note that no trees are planted within the 15 foot utility easement. Perimeter landscaping details will be provided on a landscaping figure by AHBL. Comment 7: The existing fence along the north and south sides of the property in the area that will be improved will need to be relocated in order to meet code requirements related to landscaping, screening, and setbacks. The setback requirement for fences over 6 feet in height in the C /LI zone is S feet. Response: The buffer enhancement area has been adjusted along the north property line to make room for the 5 foot fence setback/landscaping area. Per discussions with the project team, the existing fence along the south property line will be allowed to remain in place. Perimeter landscaping details will be provided on a landscaping figure by AHBL. Comment 8: A bond will be required to assure maintenance and monitoring of the enhanced buffer area. Please provide a cost estimate for 5 years of maintenance and monitoring of the 50 foot wide enhanced wetland buffer area. Response: The estimated cost for 5 years of maintenance and monitoring of the buffer area is $10,000. The City will require a case or cash equivalent of $15,000 (150% of the value of the maintenance and monitoring) to ensure that the work is performed. Comment 9: Consider use of some of the removed tree trunks as wildlife habitat features in the buffer area. Response: Figure 3 and 3A in the report and Figure 2 and 3 of the plan sheets include details for two tree trunks that will be left in the mitigation area as habitat features. 2 August 13, 2009 Mr. Chee Tung HHJ Architects, PLLC 1409 Alexander Ave E Fife, WA 98424 • City of Tukwila • Jim Haggerton, Mayo) Department of Community Development Mr. Matt Weber AHBL 2215 N 30th Street, #300 Tacoma, WA 98403 Jack Pace, Director Re: Technical Comments Letter 2 — NC Power Systems Expansion (Tukwila file #s L09 -017, L09 -018, E09 -002, PW09 -055) Dear Mr. Tung and Mr. Weber, Below is a list of technical comments for your permit applications for Tree Clearing, Special Permission, and Public Works construction permit, for the property located at 17900 West Valley Highway in Tukwila. Please revise plans and other materials according to the comments listed below. Please make sure that revisions related to the wetland buffer enhancement area will be made to the set of plans the contractor will be using for buffer enhancement, including soil preparation. 1. The proposed lighting is located within the reduced wetland buffer. The lighting fixtures and related equipment will need to be located entirely outside of the 50 -foot reduced buffer area. Please revise all plan sheets that include the proposed lighting to show that the lights will be located outside of the wetland buffer area. 2. It is not clear how the proposed lighting will be served with electricity. Please revise the plans to show the location of the electrical lines that will be serving these lights. 3. To prepare the enhancement area for plantings, you will need to decompact the soil. Please provide soil prep details and soil amendments on the Mitigation Plan (see mark -ups on attached copy of plan), as well as all construction plan sheets to be used by the contractor for grading and soil preparation.

The planting pattern currently shown on the Mitigation Plan will likely need to be revised in areas where there are utilities, in order to avoid conflicts between plantings and underground utilities. The location of new fence posts will also need to be coordinated with the location of underground utilities. 7. The existing fence along the north and south sides of the property in the area that will be improved will need to be relocated in order to meet code requirements related to landscaping, screening, and setbacks. The setback requirement for fences over 6 feet in height in the C/LI zone is 5 feet. According to TMC section 18.52..040 General Landscape and Screening Requirements (D), "Outdoor storage shall be screened from abutting public and private streets and from adjacent properties. Such screens shall be a minimum of eight feet high and not less than 60% of the height of the material stored ". Section F under this section of the TMC states that "All fences shall be placed on the interior side of any required perimeter landscaping." The required landscaping for the side yard in the C/LI zone is 5 feet, consisting of one tree per 20 lineal feet of perimeter, one shrub per 7 lineal feet of perimeter, and living groundcover to cover 90% of the landscape area within three years. Please revise plans and provide fence details to show how these requirements will be met. Landscaping will need to be coordinated with the buffer Mitigation Plan. There is no required landscaping for the rear property line. However, there is a 5 -foot rear setback requirement. Considering the potential buffer impacts involved in removing the existing fence along the eastern property line, it will be acceptable at this time to leave the existing fence in place along the eastern property line, as long as cut -outs are provided in the bottom of the fence to provide wildlife passage to the proposed buffer enhancement area. The design of these wildlife passage cut -outs is currently shown on the Mitigation Plan. 8. A bond will be required to assure maintenance and monitoring of the enhanced buffer area. Please provide a cost estimate for 5 years of maintenance and monitoring of the 50 -foot wide enhanced wetland buffer area. 9. Consider use of some of the removed tree trunks as wildlife habitat features in the buffer area. Please let me know if you have any questions about the above comments.

Please revise plans and other materials according to the comments listed below: 1) In order to accomplish buffer enhancement in the reduced 50 -foot buffer, you will need to provide more trees than just those required for the tree clearing permit. Revise the table indicating plant types and number of plantings, as well as the mitigation plan as indicated in comment number 2 below to include additional trees. 2) Revise mitigation plans to provide a landscaping plan that shows more detail in terms of location and spacing of the different types of native species plantings proposed within the proposed 50- foot reduced wetland buffer area. 3) The scale as shown is not accurate on Figures 1 and 2 of the mitigation plan — please correct this in order for us to more accurately review the mitigation plan, including pattern and spacing of plantings. 4) Provide details on how existing invasive species plants within the reduced buffer area will be removed. Please include a note stating the following: The contractor shall remove all noxious weeds and non - native plants in the stream buffer mitigation area by hand. Use of herbicides in the wetland buffer is not allowed, unless reviewed and approved by the City of Tukwila. 5) Add a note to Figure 2 of the Mitigation Plan stating that all burlap and wire around root ball shall be removed prior to planting. 6) A 5 -year maintenance and monitoring period will be required for this project, rather than the 3- year period described in application materials. Please revise the performance standards outlined on page 7 of the NC Power Systems Sensitive Areas Study and Conceptual Mitigation Plan to cover the 5 -year maintenance and monitoring period.

The site consists of a 7.0- acre parcel (King County Parcel 3623049011), developed with a commercial /industrial office building and paved surfaces on the western and central portions of the property. NC Power Systems is proposing an expansion of asphalt and concrete surfaces on the undeveloped portion of the property to the east of the current facility. A new stormwater detention pond for the new paved area is proposed to the west of the existing pond as part of this project. Request for Buffer Reduction ESA Adolfson delineated two wetlands and performed a tree study at the site. The findings of this study are described in the NC Power Systems Sensitive Areas Study and Mitigation Plan (ESA Adolfson, April 2009). Wetland A is a 380 square foot, isolated wetland located on -site in the central portion of the undeveloped area. Since Wetland A is less than 1,000 square feet in size, it is not regulated by the City of Tukwila. Wetland B is a large Type 1 wetland located off -site to the east of the NC Power property. Wetland B has a 100 foot buffer that extends onto the site. The proposed project will result in the fill of Wetland A, an isolated wetland that is not regulated by the City of Tukwila. A buffer reduction of 50 percent is also proposed for the Wetland B buffer, resulting in a 50 -foot reduced buffer width and removal of 18 cottonwood trees. An 11,835 square foot buffer enhancement area is proposed to satisfy the requirements for buffer reduction. Response to Buffer Reduction Criteria The buffer reduction criteria outlined in TMC 18.45.080.G and responses to these criteria are given below: The Director may reduce the standard wetland/watercourse buffers on a case -by -case basis, provided the buffer does not contain slopes 15 percent or greater. The approved buffer width shall not result in greater than a 50 percent reduction in width. Any buffer reduction proposal must demonstrate to the satisfaction of the Director that it will not result in direct or indirect, short -term or long -term adverse impacts to wetlands or watercourses, and that: The reduced 50 foot Wetland B buffer will be enhanced with native tree and shrub plantings and invasive species removal. The site does not contain slopes 15 percent or greater. EO9• f')02 • a. Additional protection to wetlands will be provided through the implementation of a buffer enhancement plan; Planting the 50 foot reduced buffer with native trees and shrubs will add additional protection to Wetland B, which currently has a degraded buffer, as described below. b. The existing condition of the buf er is degraded; Currently, the buffer of Wetland B is degraded and provides little water quality protection or wildlife habitat value for Wetland B. Reed canarygrass and Himalayan blackberry are the predominant existing vegetation; no trees are currently located within the 50 feet buffer that is planned for enhancement. A gravel drive currently exists within the 100 foot buffer area. A chain link fence surrounds the property. c. Buffer enhancement includes, but is not limited to the following: a. Planting vegetation that would increase value for fish and wildlife habitat or improve water quality, b.

The site consists of a 7.0 -acre parcel (King County Parcel 3623049011), developed with a commercial /industrial office building and paved surfaces on the western and central portions of the property. The area of focus for this investigation was the undeveloped eastern portion of the property. NC Power Systems (the applicant) is proposing an expansion of asphalt and concrete surfaces on the undeveloped portion of the property south of an existing stormwater detention pond at the current facility. A new stormwater detention pond for the new paved area is proposed to the west of the existing pond as part of this project. Parking areas on -site are inadequate for current and projected operations and pose a safety risk to workers moving equipment. ESA Adolfson conducted a wetland and tree study and prepared this sensitive areas study and mitigation plan in support of this development. Findings included in this letter are based on regulatory requirements presented in the Tukwila Municipal Code (TMC)— Chapter 18.45 Environmentally Sensitive Areas and Chapter 18.54, Tree Regulations, a review of existing information, and several site visits conducted from March 4th through 12`h, 2009. Document Review A review of existing literature, maps, and other materials was conducted to identify wetlands or site characteristics indicative of wetlands on the subject property. These sources can only indicate the likelihood of the presence of wetlands; actual wetland determinations must be based upon data obtained from field investigations. Documents reviewed include: • City of Tukwila Wetland Inventory (City of Tukwila GIS, 2006) • King County Soil Survey (NRCS, 2006) • Aerial Photography (USGS, 1990, 2002) • Priority Habitats and Species (PHS) Data (WDFW, 2008) The site is located in the Duwamish -Green River Water Resource Inventory Area (WRIA) 9. The Green River is located across West Valley Highway, approximately 150 feet to the west of the property boundary. According to the City of Tukwila Wetland Inventory (City of Tukwila GIS, 2006), no wetlands are mapped on the site; r ESAAdoffso NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 2 however, three linear Type 1 wetlands are mapped to the east of the property, corresponding to ditches adjacent to the Green River Interurban Trail and the rail road. The nearest is mapped adjacent to the property, running north to south near its eastern border. Two soil types are mapped along the eastern portion of the property: Woodinville silt loam and Newberg silt loam. Newberg silt loam is not listed as a hydric soil, although it may have hydric inclusions. Well- drained soils formed in alluvium characterize Newberg.soils, which are found in stream valleys. Woodinville silt loam is listed as a hydric soil. Poorly drained soils formed in alluvium, under grasses and sedges, and on stream bottoms characterize Woodinville soils. (NRCS, 2006) A mix of trees and grassy fields cover the eastern portion of the site in aerial photos from 1990 and 2002 (USGS, 2004). The detention pond and gravel drive are visible in the 2002 aerial, but due to poor resolution, are not discernable in the 1990 aerial. The commercial /industrial facility is visible in both aerials. A review of Priority Habitats and Species data did not reveal any priority habitats or species in the project area (WDFW, 2008). The nearest mapped feature is the off -site wetland located directly east of the site. Existing Conditions ESA Adolfson wetland biologist/soil scientist Laura Brock and Certified Arborist Brooke Sullivan conducted a site visit on March 4, 2009. Return visits were made on March 6, 2009 by Laura Brock and senior wetland biologist Michael Muscari, on March 7, 2009 by Laura Brock, and on March 12, 2009 by Laura Brock and Biological Resources Director /Principal Teresa Vanderburg. A mix of trees, composed of black cottonwood (Populus balsamifera) and Pacific willow (Salix lucida), and a grassy field composed of reed canarygrass (Phalaris arundinacea) cover the eastern portion of the property. The site is relatively flat, with the exception of the constructed detention pond, located in the northeastern corner of the property. Drainage features include a ditch along the northern property edge, which flows into the constructed detention pond, and a ditch along the southern property edge, which flows off -site to the east. These drainage features are regularly maintained and mowed. Weather Conditions Storms with periods of intense rain were recorded in the Tukwila area the night prior to and the morning of the initial March 4, 2009 site visit, and on March 8 and 9, 2009. Rainfall totals from the end of February through mid -March were at or near normal levels. Wetland Study During the site investigation, ESA Adolfson identified one small on -site wetland (Wetland A) in the center of the undeveloped portion of the property and an off -site wetland (Wetland B) to the east of the property (Figure 2). Wetlands were delineated using the Western Mountains, Valleys, and Coast Interim Regional Supplement (Army Corps of Engineers, 2008). Wetlands were surveyed professionally by AHBL and with a Trimble GPS r ESAAdoifsono NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 3 unit. Wetlands were rated and buffers determined using the Tukwila Municipal Code (TMC) 18.45.080. A description of delineated wetlands follows: Wetland A Wetland A is an isolated, 380 square foot wetland identified in a topographic low to the south of the gravel drive (Figure 2). According to hydrogeomorphic conditions, the wetland is a depressional wetland. Wetland A is also a palustrine, forested wetland (Cowardin et. al, 1979). Sample Plot 1 -1 characterizes the wetland (Attachment A). Hydrophytic vegetation, consisting of black cottonwood trees with an understory of reed canarygrass, covers Wetland A. ESA Adolfson observed hydric soils in Wetland A, with a gray (10 YR 5/1) silt loam identified in the first four inches. A gray (2.5 Y 5/1) silt loam with strong brown (7.5 YR 4/6 and 7.5 YR 4/6) redoximorphic features was observed in the subsoil to a depth of 20 inches. Primary sources of water to the wetland include precipitation and overland surface flow from existing paved surfaces to the west. The wetland is isolated and does not share a surface water connection to Wetland B. Soil saturation and the groundwater table were observed to the surface on the March 4, 2009 site visit. Return site visits on March 6 and 7, 2009 revealed a drop in soil saturation and water table levels, with seepage and the groundwater table observed at eight inches below the soil surface. A return site visit on March 12, 2009 revealed a further drop in soil saturation and water table levels, with saturation and the groundwater table levels observed at 10 inches below the soil surface. Based on site visits conducted in the early growing season, Wetland A appears to sustain water at a frequency and duration sufficient to support wetland hydrologic criteria. Wetland A functions at a low level due to its small size, lack of habitat features, lack of vegetation diversity, presence of invasive species, presence of nearby human activity, and disconnection from nearby wetlands and vegetated buffer corridors. The wetland provides a small amount of storage for runoff and precipitation during storm events, although the nearby detention pond provides much greater potential and opportunity for storage volume. According to TMC 18.45.080.C.3, the threshold for a regulated wetland by the City of Tukwila (City) is 1,000 square feet; therefore, Wetland A does not appear to be regulated by the City and does not have a standard buffer requirement. Because the wetland is isolated, it is not likely regulated by the Corps of Engineers (Corps). Wetland B ESA Adolfson delineated the western edge of the wetland directly adjacent to the east of the property (Wetland B). The off -site wetland is a palustrine emergent and scrub - shrub, linear, ditch -like, depressional wetland running parallel to the Interurban Trail. Areas of open water are interspersed among emergent and scrub -shrub areas along the north section of the wetland. Sample Plot 2 -1 characterizes wetland conditions in Wetland B (Attachment A). The elevation of Wetland B is approximately four to six feet lower than the NC Power Systems eastern property edge, which borders the wetland on its western side, and the Interurban Trail, which borders the wetland on its eastern side (Figure 2). Hydrophytic vegetation including Pacific willow, Sitka willow ( Sitka sitchensis), red- r ESAAdolfsa n. NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 4 osier dogwood (Corpus sericea), and reed canarygrass dominated the wetland. A brown (10 YR 4/2) silt loam was observed in the top four inches. From four to 20 inches, a brown (10 YR 4/2) silt loam with strong brown (7.5 YR 4/6) redoximorphic features was present. Primary water sources to Wetland B include runoff from storm drains, overland flow, and precipitation. A storm drainage pipe delivering water from storm drains along SW 43`d Street empties into the wetland at its southern end. ESA observed soil saturation and a water table to the surface on the March 4, 2009 site visit, with surface water over 12 inches deep was observed within five feet of the sample plot. Return site visits on March 6, 7, and 12, 2009 revealed a drop in the level of standing water present within the wetland interior. Wetland B provides a moderate to high level of functions. The size of the wetland and connection with storm water drains allows it the opportunity and potential to provide flood storage and water quality functions. The presence of standing water, large woody debris, vegetation diversity, and overhanging vegetation over portions of the wetland allow it to provide habitat functions at a moderate level. The presence of invasive species, nearby human activity along the Interurban Trail, and disconnection from nearby wetlands prevents it from functioning at a higher level. The buffer surrounding the wetland is composed of a mix of alders, willows, Himalayan blackberry, and reed canarygrass. The City of Tukwila Wetland Inventory identifies Wetland B as a Type 1 wetland. According to TMC 18.45.080.E.1, the City requires a 100 -foot standard buffer for Type 1 wetlands. The Wetland B buffer extends onto the eastern portion of the NC Power Systems property (Figure 2). Uplands Uplands completely surround Wetland A, separating it from Wetland B. Sample Plots 1 -2, 1 -3, 1-4, 1 -5, 1 -6, and 2 -2 characterize upland conditions (Attachment A). Upland areas contained a dominance of hydrophytic vegetation, consisting of reed canarygrass, black cottonwoods and Pacific willows. However, upland weeds were interspersed throughout upland areas, including: English plantain (Plantago lanceolata), common plantain ( Plantago major), Himalyan blackberry (Rubus armeniacus), and common tansy (Tanacetum vulgare). Soils varied from non - hydric, with a very dark grayish brown (10 YR 3/2) silt loam with dark brown (10 YR 3/3) redoximorphic features present to a depth of 18 inches, to hydric, with a very dark grayish brown (10 YR 3/2) to gray (2.5 Y 5/1) silt loams with dark yellowish brown (10 YR4 /4) redoximorphic features identified in the first five to eight inches of soil and a gray (2.5 Y 5/1) compacted fine sandy loam with dark yellowish brown (10 YR 4/4) redoximorphic features in the subsoil. Due to heavy rains the night prior to and the morning of the initial March 4, 2009 site visit, Sample Plots 1 -2 and 1 -5 exhibited saturation and a groundwater table present at or within 10 inches of the soil surface. However, wetland hydrology was not observed to be present in upland areas. Temporary water ponding and soil saturation within the upper 10 inches was observed to be short-lived and did not persist over eight days. Return site visits on March 6, 7, and 12, 2009 revealed drops in soil saturation and groundwater table levels. On the March 12, 2009 site visit, no saturation and no groundwater table was observed in Sample Plots 1 -2 and 1 -5. Hydrologic conditions observed in these upland plots are likely due to the presence of the compacted fine sandy loam beneath silt loam in the surface layer, which impedes percolation through the soil profile. High intensity storms and the large amount of runoff generated from existing paved surfaces on -site have the potential to create brief periods of r • ESAA.oIfson NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 5 saturation with an associated perched water table. Based on the drainage observed at these plots, these areas do not appear to sustain water at a frequency and duration sufficient to support wetland hydrologic criteria, and therefore, do not appear to meet the jurisdictional definition of a wetland. Tree Study ESA Adolfson wetland biologist/soil scientist Laura Brock and Certified Arborist Brooke Sullivan conducted a tree study on March 4, 2009. Trees within the project area consist of 78 cottonwoods bordering the existing paved area and gravel drive and five Pacific willows present in the central portion of the property (Figure 2). Tree locations and diameters at breast height (DBH) are shown on Figure 2. According to the property owner, limbs from cottonwoods on -site continually break off, posing a safety and property damage risk. Within the 100 -foot standard buffer of Wetland B are 18 cottonwood trees. The diameters of these cottonwoods range from eight to 22 inches (Figure 2). Project Impacts and Regulatory Implications The proposed project will result in the fill of Wetland A (38,0 square feet), which is an isolated wetland that is not regulated by the City, and a buffer reduction for Wetland B (Figure 3). According to TMC 18.45.080.G.1, a proposed 50 percent reduction of the standard buffer width may be allowed by the Director on a case by case basis. The 18 cottonwood trees within the outer 50 percent of the Wetland B buffer will also be removed, pending approval of the proposed buffer reduction (Figure 3). Since these cottonwoods are within a sensitive area buffer, they are subject to the City's Tree Regulations (TMC 1.8.54). To satisfy regulatory requirements of the City, a Type 2 Special Permission Permit for the buffer reduction and a Tree Clearing Permit for cottonwood tree removal within the Wetland B buffer is required. Permit approval and issuance is dependent upon satisfying requirements of the TMC and specific criteria outlined in each permit. A discussion of the proposed mitigation and its fulfillment of buffer reduction and tree removal criteria is included in the next section. Proposed Mitigation Mitigation sequencing has been followed for this project as required by TMC 18.45.090.C. NC Power has investigated expanding operations of the existing facility off -site and recently acquired the property to the south of the project area to facilitate this. Wetland impacts are proposed for Wetland A, a low quality wetland in a disturbed setting, rather than Wetland B, a Type 1 wetland. Mitigation that is proposed will enhance and improve the current functions of the Wetland B buffer and provide better protection for the remaining wetland. Wetland A is an isolated wetland and is not regulated by the City; therefore, no mitigation is required for fill. Alteration of Wetland A will not adversely impact existing functions on -site because the wetland is small, isolated from Wetland B, and is located in a disturbed setting. The stormwater storage function that Wetland A provides will be replaced and improved by a new stormwater detention pond constructed on -site to the west of the existing pond. ESA A i no NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 6 To allow for a reduced Wetland B buffer (50 feet), the remaining onsite buffer (11,835 square feet) will be enhanced. Tree replacement for the cottonwoods removed during expansion of the parking area will also be provided as part of the buffer enhancement. Figure 3 shows the proposed mitigation area. Buffer Enhancement and Tree Replacement The reduced 50 foot Wetland B buffer will be enhanced with native tree and shrub plantings and invasive species minimization and removal (Figure 3). Currently, the buffer of Wetland B is degraded and provides little water quality protection or wildlife habitat value for Wetland B. A gravel drive exists within the 100 foot buffer area, and will be removed as part of this enhancement plan. Reed canarygrass and Himalayan blackberry are the predominant existing vegetation; no trees are currently located within the 50 feet buffer that is planned for enhancement. Planting a diverse native tree and shrub community will add additional protection to Wetland B, increase wildlife and aquatic habitat, improve water quality, and reduce non- native, invasive plant species; thereby fulfilling the criteria listed in TMC 18.45.080.G.2 and the Type 2 Special Permission Permit. Tree replacement ratios given in TMC 18.45.1.30.3 were used to calculate the number of trees required for mitigation of the 18 cottonwood trees that are to be removed. A total of 47 trees will be planted in the Wetland B buffer to fulfill requirements listed in TMC 18.54.130.3 and the Tree Clearing Permit. Since there are no trees currently within the planned enhancement area, no tree retention, protection, or relocation is proposed. Tree removal will occur in the outer 50 percent of the Wetland B buffer, away from Wetland B and existing shrub vegetation that lines the wetland. Trees to be removed are in an area downslope of the inner 50 percent of the Wetland B buffer; therefore, the risk of erosion and runoff is low. Tree replacement ratios and calculations, planting schedule, and planting details are given in Table 1 and in Figure 3. Table 1.

The wetland buffer currently provides low function due to the lack of vegetation structure and species diversity, and the presence of invasive species. ►` ESAAdolfson* NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 7 The main project objectives are: • Plant a diverse, native, upland tree and shrub community within the reduced 50 -foot Wetland B buffer, which will include a greater diversity of species than existing conditions and will minimize existing nonnative, invasive species. • Replace trees removed from the standard buffer area in the wetland enhancement area. Performance Standards A set of specific performance standards has been established that corresponds to the stated mitigation goals and objectives. These standards serve as the benchmarks that will be used to evaluate the success of the mitigation project. Following monitoring, a determination can be made as to the need for implementing a contingency plan. The proposed performance standards are as follows: • 100 percent survival of installed shrubs and trees within one year of mitigation installation; • Soil deconsolidated to at least a 12 -inch depth at the time of installation; • 30 percent cover of installed shrubs and trees within two years after mitigation installation, and 60 percent cover within three years; • Less than 10 percent cover of non- native invasive species (excluding reed canarygrass) within three years of mitigation installation, and less than 20 percent cover of reed canarygrass within three years. Reed canarygrass currently covers almost 100 percent of the buffer area and complete eradication is not feasible within three years. The project will minimize the extent of reed canarygrass in the buffer through annual maintenance activities. Shade created as native plants become established will further reduce the amount of reed canarygrass present. Monitoring Plan The main objective for mitigation monitoring is to document the level of success in meeting the performance standards described above. An initial stem count of the installed shrubs and trees will be conducted following construction (an as -built count). Monitoring of mitigation areas will continue for three years post - construction. A qualified biologist or landscape designer will conduct the monitoring. The as -built plan will be used to as the basis for monitoring of plant survival. Monitoring will begin the first full growing season after construction is complete and the plants have been installed. Shrub and tree cover will be evaluated quantitatively and qualitatively one year after construction and each year thereafter for three years. The following information will be recorded during the monitoring site visit: • Survival rates of installed vegetation; • General plant health assessment; • Documentation of the presence of undesirable plants (weedy and /or non - native species) with estimated percent cover; r ES4 ifs n NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 8 • Photo documentation of site conditions; • Impacts to the wetland buffer from human use (e.g., dumping of debris); and • Signs of wildlife use of the area. Reporting Monitoring reports will be prepared for review and approval by the City of Tukwila. The reports will compare the performance standards described in the final mitigation plan to the field observations, and will recommend species replacements or other maintenance activities, if necessary (see Maintenance section below). Reports will present data collected during the monitoring site visit, and document successes in meeting specific performance standards. Photographs will be included to illustrate and document site conditions. Monitoring reports will be submitted to the City by December of each monitoring year. Maintenance Maintenance of the mitigation area will begin after completion of the project and continue, as needed, for three years. After the initial planting acceptance by the project biologist, the landscaping contractor will be responsible for plant survival for a period of one year. NC Power would provide maintenance, as necessary. Maintenance could include, but may not be limited to: • Watering or providing irrigation during unseasonable dry periods or when the soils are unusually dry; • Removing non - native or invasive plant species as needed; • Providing soil amendments and /or mulch as needed; • Providing fencing around woody plants to prevent animal damage as necessary; • Providing fencing to prevent vandalism or damage caused by humans; and • Installing supplemental plantings as needed. Contingency If any portion of the mitigation is not successful, a contingency plan will be implemented. Such plans are prepared on a case -by -case basis to remedy any aspects of the mitigation that do not meet the performance standards. The plan, if required, would be developed in cooperation with the City. Summary NC Power is proposing expansion of paved surfaces at their current facility, located at 17900 West Valley Highway, in Tukwila, WA. ESA Adolfson performed sensitive area and tree studies and prepared this report to support sensitive areas permitting for the NC Power project. Two wetlands were identified within the project area (Figure 2). A summary of these wetlands is given in Table 2: r E Adolfso n NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 9 Table 2.

A buffer reduction of 50 percent is also proposed for the Wetland B buffer, resulting in a 50 -foot reduced buffer width and removal of 18 cottonwood trees. To mitigate for project impacts, NC Power is proposing an 11,835 square foot buffer enhancement and tree replacement area which will improve wildlife habitat, increase vegetation structure and diversity, and provide additional protection for Wetland B (Figure 3). Mitigation for fill of Wetland A is not required because it is an isolated wetland that is not regulated by the City. • r E n • NC Power Sensitive Areas Study and Mitigation Plan April 16, 2009 Page 10 Limitations Within the limitations of schedule, budget, and scope-of-work, we warrant that this review was conducted in accordance with generally accepted environmental science practices, including the technical guidelines and criteria in effect at the time this study was performed.

Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60 -day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant.
