These cables are vital to CenturyLink's system as they contain circuits that are of an extremely sensitive nature affecting National Security, Local and Interstate Commerce, Local and Regional Emergency Readiness, and Local, Regional and National Telecommunications. In 2011, CenturyLink obtained permits from the City of Tukwila and the City of Kent to construct a temporary, single -span aerial fiber optic crossing of the Green River. CenturyLink installed a temporary aerial crossing due to the potential risk of flood waters released by Howard Hanson Dam damaging the fiber optic cables in conduit attached to the roadway bridge at South 180th Street. The permit for the temporary aerial crossing was conditioned for removal within three years of construction. Therefore, CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, adjacent to South 200th Street right-of-way, to connect the existing underground fiber optic cables on the east and west sides of the Green River. The crossing will be done through a horizontal direction drill (HDD) technique. The eastern portion of the project from the mid -channel of the Green River is located within the City of Kent. The western portion of the project from the mid -channel of the Green River is within the City of Tukwila. This memorandum provides information on the existing conditions and potential project impacts to streams, wetlands, fish and wildlife, and trees within the project area. Project Location and Description The project is located in portions of the City of Tukwila and the City of Kent (Section 2, Township 22 North, Range 4 East), and is shown in Figure 1. The HDD portion of the crossing will be approximately 700 feet long and will be constructed approximately 30 feet below the riverbed. A 12 -inch HDPE casing and four, 4 - inch -diameter conduits will be pulled through the bore and trenching will connect the conduits to existing manholes on each end of the project. The project will include excavating a 20 -foot -long by 8 -foot -wide by 4 -foot -deep pit to launch the HDD from the CenturyLink — South 200th Street Green River Crossing May 2013 Environmental Assessment 1 HR west side of Green River and excavating a 20 -foot -long by 8 -foot -wide by 4 -foot -deep pit on the east side of Green River to pullback the conduits and casing. Work within City of Tukwila An approximately 900 -foot -long, 2 -foot -wide open -cut trench will connect the cable from the launching pit to the existing Manhole 928 within the South 200th Street right-of-way and the undeveloped, private parcel (5201 South 200th Street, Parcel No. 022204-9015). The launch site will require disturbing approximately 10,000 square feet and a 12 -foot - long, 6foot-wide, 8 -foot -deep vault will be installed at the launch point. There is an existing .gravel access road to the project area. The contractor staging will be located on the private parcel through obtaining a temporary construction easement. Upon completion of construction the site will be restored to the current condition as a vacant site prepared for future development. Work within City of Kent The eastern terminus of the project will be located within the Three Friend's Fishing Hole Community Park. The HDD will terminate at a new 6 -foot by 12 -foot by 13—foot deep precast concrete vault. The vault will be set over the top of an existing CenturyLink duct bank at the corner of South 200th Street and 58th Place SE. The casing pipe and conduits will be pulled into the bore which will require stringing the pipe along South 196th and closing 58th Place SE for a short period of time. Upon completion of construction, the excavations will be backfilled and the site will be restored to the current condition as a public park. 2.0 Methods The field investigation included two steps. The first step was a review of existing documents such as federal and state agency species lists, City and King County wetland and stream inventories, wetland and stream reports for adjacent properties, and other environmental documents. The second step was a field investigation of the site. Document Review The following existing documents were reviewed prior to beginning the field work: • Soil Survey of King County Area, Washington (Snyder et al. 1973) • National Wetland Inventory maps (http://www.fws.qov/wetlands/data/Mapper.html - accessed 2/26/2013) • King County GIS (IMAP http://www.kingcountv.gov/operations/GIS/Maps/iMAP.aspx — accessed 2/26/2013) • City of Kent Wetland Map (http://www.ci.kent.wa.us/publicworks/maps.aspx - accessed 2/26/2013) • USGS Washington Streamflow Data (http://waterdata.usgs.gov/WA/nwis/current/?type=flow — accessed 2/26/2013) • Habitat limiting Factors and Reconnaissance Assessment Report, Green/Duwamish and Central Puget Sound watersheds (WRIA 9 and Vashon Island) (Kerwin and Nelson 2000) • Washington Sate Department of Fish and Wildlife (WDFW) Priority Habitats and Species database (http://wdfw.wa.gov/mapping/qhs/), accessed 2/26/2013 • WDFW SalmonScape http://wdfw.wa.qov/mappinq/salmonscape/index.html - accessed 2/26/2013 • City of Tukwila Shoreline Master Program. (City of Tukwila 2011) CenturyLink — South 200th Street Green River Crossing Environmental Assessment May 2013 2 • City of Kent Shoreline Master Program (City of Kent 2009) Field Methods An HDR biologist conducted a site visit on February 27, 2013. The field investigation included the identification of streams and wetlands in the project area, but no formal delineation of wetland (not present) or Ordinary High Water Marks (OHWMs), since sufficient survey data is already present for the Green River OHWM. The study area extended approximately 100 feet south from 200th Street from the proposed cable alignment. All trees greater than 6 -inches in diameter at breast height and woody shrubs located within the immediate vicinity of the proposed cable alignment location were located using a Trimble GeoXT 2005 handheld GPS receiver and field personnel documented the dripline for each identified tree and made notes on the general health of trees within the limits of utility footprint. The dripline was determined by measuring the greatest distance to the outer edge of the crown. Trees were visually surveyed for decay, damage, or decline (see Figure 2). Site photographs were taken to document existing site conditions. 3.0 FIncHngs Streams The Green River is the only water body in the project area. The proposed project is located at approximately river mile (RM) 16.75. Cities of Tukwila and Kent classify the Green River as a Type 1 stream, which are inventoried as a Shoreline of the State. Both cities regulate Type 1 streams under their Shoreline Master Program. Table 1 summarizes local ratings and shoreline jurisdictions of the Green River for the cities of Tukwila and Kent. Table 1. Summary of Local Regulations of the Green River in the Project Area Stream Tributaryto Jurisdiction Local Ratin ga Shoreline Designation" Width' Green River Duwamish Waterway Tukwila Type 1 Urban Conservancy 125 feet Kent Type 1 Urban Conservancy Open Space 200 feet a City of Tukwila Municipal Code 18.44 and 18.45.10; City of Kent Municipal Code 11.04 and 11.06 b City of Tukwila Shoreline Master Program (2011) ; City of Kent Shoreline Master Program: Ordinance No.3931 (2009) The Green River is located within the Green/Duwamish River Watershed (Water Resource Inventory Area [WRIA] 9), and the Green/Duwamish River basin encompasses approximately 566 square miles. The Green River originates in the Cascade Mountains and flows northwesterly for approximately 93 miles before draining into the Duwamish Waterway and Elliott Bay (Kerwin and Nelson 2000). Within the project area, the Green River flows south to north. Levees are present along both banks of the Green River at the proposed communication line crossing location. These levees were constructed in the early 1900s and have been maintained by the Green River Flood Control Zone District (City of Kent 2009). On west side of the bank, the Green River regional trail is located on top of the levee and runs along the Green River. In an effort to help preventing flooding in the Green River valley, the City of Tukwila CenturyLink — South 200th Street Green River Crossing Environmental Assessment May 2013 3 has placed sandbags on top of the levee of the west bank (City of Tukwila 2009). These sandbags have been removed. The banks of the Green River in this reach are generally steep but natural outside of the South 200th Street bridge footprint. Dominant species observed in the study area include Himalayan blackberry (Rubus armeniacus), Sitka willow (Salix sitchensis), Pacific willow (Salix lasiandra), and reed canarygrass (Phalaris arundinacea). Dominant tree species include planted spruce (Picea sitchensis) and Douglas fir (Pseudotsuga menziesii), volunteer red alder (Alnus rubra), and black cottonwood (Populus balsamifera). The east side of the channel is similarly dominated by willow shrubs, with dense thickets of Himalayan blackberry and a few scattered Japanese knotweed (Polygonum cuspidatum). There appears to have been stream restoration work in this reach, as several pieces of large woody debris have been placed in the east side of the channel and native riparian shrub (dogwood, Cornus alba) and tree species (Douglas fir) have been interplanted along the stream bank. Wetlands Two wetlands were identified in the project vicinity in the priority habitat and species map and City of Kent Wetland map. One wetland is mapped south of 200th Street on the west bank of the Green River, and a smaller wetland is mapped on the east bank. However, substantial development has taken place in the area since this mapping was completed. The area to the south of South 200th Street and west of the Green River has been extensively graded, and the area to the east (at Russell Road South) consists of landscaped lawn, with a few ornamental trees. Natural vegetation in the project area is limited to the banks of the Greek River. No wetlands were identified in the project area during the field investigation. Fish and Wildlife The cities of Tukwila and Kent have both designated the Green River as Fish and Wildlife Habitat Conservation Areas (FHWCAs) because the Green River provides habitat for salmonid species that are listed as threatened species under the Endangered Species Act. The Green River is documented to support eight anadromous fish species, including Chinook salmon (Oncorhynchus tshawytscha), steelhead trout (0. mykiss), coho salmon (0. kisutch), sockeye salmon (0. nerka), chum salmon (0. keta), pink salmon (0. gorbuscha), coastal cutthroat (0. clarki clarki), and bull trout (Salvelinus confluentus) (WDFW 2010a; WDFW 2013; Kerwin and Nelson 2000). Out of eight species, Chinook salmon, steelhead trout, and bull trout are listed as threatened species. In addition, resident population of coastal cutthroat trout is also reported to occur in the Green River (Kerwin and Nelson 2000). Although there is a continuing effort of restoring the riparian condition of the Green River in the project vicinity, suitable spawning habitat is likely absent at this reach. Presence of these species is limited to migration and rearing at the proposed project location (WDFW 2010b; Kerwin and Nelson 2000). According to the WDFW Priority Habitats and Species database (WDFW 2010a), two osprey (Pandion haqliaetus) nests have been identified in the vicinity of the project area (approximately % to one mile from the site). Osprey are a state monitor species, but are not federally listed and are not considered a priority species by Washington state. Osprey are pisciverous hawks, and may use the Green River in the project vicinity for foraging. Waterfowl concentrations are also mapped in the immediate proximity of the project (immediately south of South 200th Avenue), however, this are has been extensively CenturyLink - South 200th Street Green River Crossing Environmental Assessment May 2013 4 Ian graded and currently has neither water nor vegetation that would support waterfowl concentrations. No other priority habitat species have been documented to occur in the project vicinity (WDFW 2013). Tree and Shrub Survey A total of 45 trees and shrubs were documented within the study area, 25 on the west side and 20 on the east side of the Green River. Tree species observed within the project study area include big -leaf maple, red alder, common hawthorn, Sitka spruce, black cottonwood, Douglas fir, various willows (Salix sp., unidentified), western red cedar, and several ornamental species. Table 2 presents the species, diameter at breast height (dbh), and condition of trees and shrubs observed. Locations of these trees are also shown in Figure 2.

The proposed project will remove some areas of mowed grasses and ornamental plants at the proposed underground cable and termination pole locations. These areas will be restored to the present condition upon completion of construction. Therefore, no impacts from the operation of the proposed communication line are anticipated. As a result, the proposed project will have no impacts on sensitive areas including wetlands, streams, and fish and wildlife habitat; therefore, no mitigation measures are proposed for this project. 5.0 References Kent, City of. 2009.

Work below the ordinary high water mark is covered in Part C. Please mark the appropriate response. NO - Continue to Question 1-2 YES - Continue to Question 1-2 1-2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and/or sedimentation in watercourses, the Green/Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please mark the appropriate response. NO - Continue to Question 1-3 ✓ YES - Continue to Question 1-3 A Temporary Erosion Control Plan will be submitted. 1-3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development. Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development (TMC 18.06.445). Please mark the appropriate response. ✓ NO - Continue to Question 2-0 (Page 2) YES - Continue to Question 1-4 1-4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater treatment and management system intended to contain all stormwater on site by allowing it to seep into pervious surface or through other means to be introduced into the ground. If your project involves the construction of impervious surface and does not include the design of a stormwater management system specifically designed to infiltrate stormwater, answer Yes to this question.

There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. In 2011, CenturyLink (formerly Qwest Communications) obtained permits from the City of Tukwila and the City of Kent to construct a temporary, single-span aerial fiber optic crossing of the Green River at 181st Street. CenturyLink installed a temporary aerial crossing due to the potential risk of flood waters released by Howard Hanson Dam damaging the fiber optic cables in conduit attached to the roadway bridge at South 180th Street. The permit for the temporary aerial crossing was conditioned for removal within three years of construction. Therefore, CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, adjacent to South 200th Street right-of-way to connect the existing underground fiber optic cables on the east and west sides of the Green River. The crossing will be done through a horizontal direction drill (HDD) technique and open -cut trench. The eastern portion of the project from the mid -channel of the Green River is located within the City of Kent. The western portion of the project from the mid -channel of the Green River is within the City of Tukwila. The HDD portion of the crossing will be approximately 700 feet long and extend approximately 30 feet below the riverbed. Approximately four 4 - inch -diameter conduits will be pulled under the Green River. The project will include excavating a 20 -foot -long by 8 -foot -wide by 4 -foot -deep pit to launch the HDD from the west side of Green River and excavating a 20 - foot -long by 8 -foot -wide by 4 -foot -deep pit on the east side of Green River to pullback the conduits. Within the City of Tukwila, an approximately 900 -foot -long, 2 -foot -wide open -cut trench will connect the cable from the launching pit to the existing Manhole 928 within the South 200th Street right-of-way and the undeveloped, private parcel (5201 South 200th Street, Parcel No. 022204- 9015). The launch site will require disturbing approximately 10,000 square feet and a 12 -foot -long, 6 -foot -wide, 8 -feet -deep vault will be installed at the launch point. There is an existing gravel access road to the project area. The contractor staging will be located on the private parcel through obtaining a temporary construction easement from the property owner. CenturyLink is currently working with the property owner to secure easements for the project. Upon completion of construction the site will be restored to the current condition as a vacant site prepared for future development. Within the City of Kent, the project will be located within the Three Friend's Fishing Hole community park. The conduits will terminate at a new 6 -foot by 12 -foot by 13—foot deep precast concrete vault. The vault will be set over the top of an existing CenturyLink duct bank at the corner of S. 200 Street and 58th Place SE. Upon completion of construction, the excavations will be backfilled and the site will be restored to the current condition as a public park. SEPA Checklist Agency Comments Page 2 SEPA Checklist Please respond to all questions. Use separate sheets as necessary. Applicant Responses: 11. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, the tax lot number, and section, township, and range.

While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project would extend from an existing Manhole (Manhole 928) within the South 200th Street right-of-way. The fiber optic cable would be launched from 5201 South 200th Street (Parcel 022204-9015) under the Green River, and be pulled from the Three Friends Fishing Hole Community Park within the City of Kent right-of-way. See design drawings. 12. Does the proposal lie within an area designated on the City's Comprehensive Land Use Policy Plan Map as environmentally sensitive? The western portion of the project is located within the Tukwila South Overlay District and not within an area designated as environmentally sensitive. The eastern portion of the project is located within an area designated as Parks and Open Space within the City of Kent Comprehensive Plan and not within an area designated as environmentally sensitive. Agency Comments t, 61/4tetvv'm f i� gtry,,,� fiL Page 3 Please respond to all questions. Use separate sheets as necessary. Applicant Responses: B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other: The project site has been graded to a generally flat grade in preparation for future development. The project site is intersected by the Green River. The portion of the project within the City of Kent is generally flat and slopes down gradient to the Green River. There is a rolling hill within the Three Friends Fishing Hole Community Park that is a portion of the levee. b. What is the steepest slope on the site (approximate percent slope)? The banks of the Green River range from 35% to 50% slopes within the project area. The rest of the project site is generally flat with slopes no greater than 5%. Any earthwork will be done in areas where the slope is less than 5%. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. According to the Natural Resources Conservation Services (NRCS), the project site consists of Alderwood and Kitsap soils, Everett gravelly sandy loam, Newberg silt loam, Nooksack silt loam, Renton silt loam, Snohomish silt loam, and Urban land. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There are no known surface indications or history of unstable soils in the immediate vicinity. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. The portion of the project within the City of Tukwila would require approximately 290 cubic yards of excavation and approximately 74 cubic yards of fill for the open -cut trench along the South 200th Street right-of- way, the HDD launch site, and the HDD crossing alignment. The portion of the project located within the City of Kent would require approximately 134 cubic yards of excavation and approximately 110 cubic yards of fill for the open -cut trench within the Three Friends Fishing Hole Community Park, the HDD receiving site, HDD crossing alignment, and the vault entrance and penetration site. The contractor would determine the source of the fill material. SEPA Checklist Agency Comments Page 4 1111111 SEPA Checklist Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. There would be a potential for erosion to occur during construction of the open -cut trenches, HDD launch site, and HDD receiving site. Erosion could occur during installation and removal of erosion and sediment control structures, trench excavation, conduit installation, soil stockpiles, truck traffic, final grading prior to restoration, and other construction activities. Soils temporarily exposed during construction could be eroded by stormwater. Standard erosion control measures would be implemented to mitigate these potential impacts. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project would include buried fiber optic cables and would not increase the amount of impervious surface on the portion of the project within the City of Tukwila. A temporary staging area would be constructed to launch the directional bore under the river. Upon completion of construction, the staging area would be removed and restored to the current condition. A 6 -foot -wide by 10 -feet -long vault would be installed within the portion of the project located in the City of Kent. The vault would be accessed by a 3 - foot -diameter vault lid. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Erosion and sediment control (ESC) for the project would rely on structural measures (e.g. silt fences, straw bale barriers, and plastic covering) and non-structural measures (e.g. common-sense planning, good design, routine inspection and maintenance, employment and enforcement of non -ESC Best Management Practices). Once permanent erosion control is in place (revegetating or paving), no other erosion control measures would be required. 2. Air a. What types of emissions to the air would result from the proposal (for example, dust, automobile odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Temporary air quality impacts may occur during construction due to fugitive dust emissions caused by clearing, excavation, uncovered stockpiles, and any other construction. Fugitive dust has the potential to be of greater concern during dry, warm weather conditions when wind and construction equipment create more dust. Localized increases in exhaust emissions from equipment and vehicle operation would occur during construction; however, emissions would not likely be great enough to noticeably affect air quality. Page 5 OS N SEPA Checklist , Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments The operation and maintenance of the crossing may require periodic use of equipment and vehicles; however, emissions would not likely be great enough to noticeably affect air quality. b. Are there any off-site sources of emissions or odor that may affect your proposal. If so, generally describe. There are no known off-site sources of emissions or odor that would affect the project. c. Proposed measures to reduce or control emissions or other impacts to air, if any: The Puget Sound Clean Air Agency (PSCAA) governs activities affecting air quality in King County. The project would be constructed in compliance with the PSCAA requirements. Fugitive dust impacts associated with construction of the proposed project are not anticipated to be significant. Construction contractors would comply with the regulatory requirements and implement appropriate mitigating measures as necessary. Vehicular emissions associated with construction would be short term in nature. The completed project would not produce emissions. 3. Water a. Surface: 1. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The Green River intersects the project site. The Green River turns into the Duwamish Waterway and flows into Puget Sound. The City of Tukwila and City of Kent sensitive area maps indicate there are no potential wetland areas in the vicinity of the project. 2. Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, connecting the existing underground fiber optic cables on the east and west sides of the Green River. The crossing would be done through a horizontal direction drill (HDD) technique. The eastern portion of the project from the mid -channel of the Green River would be located within the City of Kent. The western portion of the project from the mid -channel of the Green River would be within the City of Tukwila. The HDD portion of the crossing would be approximately 700 feet long and extend approximately 30 feet below the riverbed. Approximately four 4 -inch -diameter conduits would be pulled through the bore. The Page 6 SEPA Checklist Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments launch and receiving sites for the HDD would be located outside the shoreline jurisdiction on both sides of the river (Tukwila on the west and Kent on the east). See the attached design drawings for the proposed project. 3. Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Fill and dredge material would not be placed within the surface waters or wetlands. 4. Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities, if known. The project would not require diversion or withdrawals of surface waters. 5. Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. The project would include boring 30 feet under the Green River using the HDD technique. According to the Federal Emergency Management Agency (FEMA) maps, a 100 -year floodplain is identified along the Green River. The HDD would require a launch site and receiving site. These sites would be located outside the 100 -year floodplain. As the project includes buried facilities, the project would not include surface clearing and grading within the 100 -year floodplain. See the attached design drawings showing the 100 -year floodplain. 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. The project would not involve discharges of waste materials to surface waters. b. Ground: 1. Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities, if known.

Water Runoff (including storm water): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow? Will this water flow into other waters? If so, describe. The source of runoff during construction would be precipitation. If needed, runoff would likely be collected, treated, and disposed of using culverts, ditching, or pumping. Erosion control measures would be applied during construction as noted in B.1.h. 2. Could waste materials enter ground or surface waters? If so, generally describe. Waste materials are not anticipated to enter the ground or surface waters during construction or operation of the proposed project. With the HDD bore technique, there is the potential for drilling mud to enter stream channel during the boring channel through fractured bedrock that is referred to as a "frac-out." d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Measures to reduce or control surface, ground, and runoff water may include the following: • Minimize area of disturbance to the amount necessary for construction and project features. • Stabilize exposed soils immediately following construction. • Implement erosion and sedimentation control (ESC) measures to address erosion control during construction. To minimize the potential for frac-out the following measures would be implemented: • Use nontoxic bentonite -clay mixtures of drilling mud to ensure that, if frac-out occurred, it would not result in toxicity to aquatic life. • The contractor would be experienced in performing HDD drilling. • During construction, have a frac-out containment response kit on-site and accessible.

In 2011, Centurylink (formally Qwest) obtained permits from the cities of Kent and Tukwila to construct a temporary, single span aerial fiber optic crossing above the Green River at S. 181st Street. This overhead crossing was installed due to the potential risk of flood water being released by the Howard Hanson dam and damaging the existing fiber optic crossing on the roadway bridge at S. 180th Street. The permit for the temporary aerial crossing was conditioned that the crossing be removed within three years of construction. In order to respond to this condition, Centurylink is proposing to install a permanent buried fiber optic crossing at the Green River, adjacent to S. 200th Street. The crossing will be done through a horizontal direction drill (HDD) technique and open -cut trench. The eastern portion of the project from the mid -channel of the Green River is located within the City of Kent. The Western portion of the project from the mid -channel of the Green River is located within the City of Tukwila. Each city is reviewing and processing their own shoreline permits for the work within their respective jurisdictions. Within the City of Tukwila, an approximately 900 foot long, two foot wide , open cut trench will connect the cable from the launching pit to an existing manhole within the right of way of S. 200th Street. This work all occurs outside of the shoreline jurisdiction. The launch site (where the boring will begin) is approximately 600 feet from the ordinary high water mark. At this location the applicant will direction drill under the Green River, up to a maximum depth of 30 feet below the bed of the River. No vegetation or land altering will actually take place within the shoreline environment.

BM H:\Developments\Century Link\Shoreline Staff Rpt.doc Page 1 of 5 07/22/2013 2:42:00 PM 3. TUKWILA'S SHORELINE MASTER PORGRAM-BACKGROUND The City of Tukwila adopted a new Shoreline Master Program (SMP) on August 15, 2011, which was approved by the Washington State Department of Ecology on October 14, 2011 and become effective on October 28, 2011. A. Shoreline Environment Designation The shoreline environment designation for the site is Urban Conservancy; the purpose of the Urban Conservancy Environment is to protect ecological functions where they exist in urban and developed settings, and restore ecological functions where they have been previously degraded, while allowing a variety of compatible uses. The proposed project will be working within the buffer of the shoreline. Pursuant to SMP 8.5.A.1.j, utilities are a permitted use within the shoreline zone. The telecommunications line will be placed below the River. No ground disturbances will occur within the 200 foot shoreline jurisdiction. B. Shoreline Goals and Policies The following section discusses the Shoreline Master Program goals and polices that apply to this project and are excerpted from Chapter 6 of the City's SMP. Goal 6.3 Economic Development Goal: Development along the shoreline that fosters economic vitality of Tukwila while preserving the long term benefits of the river. Response: the proposed project will place a telecommunications line below the Green River. The telecommiucations line will be available to businesses throughout. Renton, Kent, Tukwila, and south King County. Placing the conduit lines below the River increases the likelihood that the line will be available in the event of a natural disaster. Goal 6.4 Private Property Rights Goal: Protect rights of property owners to reasonable use and enjoyment of private property, through appropriate location, access to, and design of shoreline uses. Response: The applicant has secured permission from adjacent property owners to complete the proposed project. Goal 6.6 Access and Recreational Use Goal: Increase the amount of diversity of opportunities for public creation and access to and along the river, including visual and cultural access, access to the water's edge, opportunities for BM H:\Developments\Century Link\Shoreline Staff Rpt.doc Page 2 of 5 07/31/2013 3:03 PM 1- small boat navigation and access, and connections to other neighborhoods, consistent with the shoreline character. Response: The proposed project will have no impact on public access or recreational opportunities along the River. Goal 6.8 Historical Resource Use and Archaeological Protection Goal: Recognition of the of the river's contribution to Tukwila history and community identity through identification, enhancement, restoration, and protection of sites with historic and cultural value and through development of interpretive and educational programs. Applicable Polices: • Policy 5.8.3 Response: Placing the conduit below ground via the boring method eliminates much of the impacts associated with open trenching, thus eliminating the chances that artifacts or sites will be disturbed. 6.9 Natural Environment and Habitat Use Goal: Restored, enhanced and protected natural environment resources along the river, including trees, wildlife habitat and features with value for long-term public, scientific, and educational uses. Applicable Polices: • Policy 5.9.1 • Policy 5.9.2 Response: The applicant prepared an "Environmental Assessment (hereinafter "Assesment") dated May 10, 2013 that examined the impacts to the natural environment as a result of the proposed boring project. The Assessment concluded, "...no impacts from the operation of the proposed communication line are anticipated. As a result, the proposed project will have no impacts on sensitive areas including wetlands, streams, and fish and wildlife; there for no mitigation measures are proposed for the project." Staff concurs with the conclusion provided in the Assessment and does not think that additional mitigation above and beyond what is proposed in the plans and application is needed. 6.10 Water Quality. Surface Water and Flood Control Use Goal: Improved water quality and quantity control programs affecting the Green/Duwamish River that improve the river's quality, provide habitat for fish and wildlife, protect public health and safety, and enhance public enjoyment of the river. BM H:\Developments\Century Link\Shoreline Staff Rpt.doc Page 3 of 5 07/31/2013 3:03 PM Applicable Polices: • Policy 5.10.1 • Policy 5.10.03 Response: Placing the fiber optic line below the ground will have no impact on water quality, surface water, or flood control. 4. SHORELINE REGULATIONS TMC 18.44.130(B)(3) states that a substantial development permit shall be granted only when development proposed is consistent with the shoreline master program. The relevant SMP polices were discussed above. Below is a discussion of the relevant shoreline master program regulations that are incorporated into the zoning code that apply to the permit application. Criteria Applicable TMC Complies with Criteria? Permitted Uses 18.44.060 Yes. Development Standards 18.44.070(B)(1)(c) Yes. Placing the utility below ground provides sufficient screening. Surface Water and Water Quality 18.44.070 (D) Yes Landfill Activities 18.44.070 (J) Yes Vegetation Protection and Landscaping 18.44.080 Yes Public Access 18.44.100 Yes. Public access is only required when a development or use would create additional demand for public access through the addition of square footage to an existing building or the intensification in land use. The project will not create additional demand for public access. Shoreline Design Guidelines 18.44.110 Not applicable. No structures are proposed. 5. COMMENTS A Notice of Application was distributed to potentially impacted agencies, the public, and posted on site on June 14, 2013. No comments were received.

The crossing between the cities of Kent and Tukwila will occur at S. 200th Street, with the fiber optic line being placed beneath the Green River. The crossing of the Green River will be completed using horizontal direction drill technique, with the fiber optic line being placed 30 feet below the riverbed. Pursuant to WAC 197-11-942 the City of Kent has transferred SEPA lead agency status to the City of Tukwila. The City of Tukwila will conduct the environmental review for all work associated with the project and then issue a threshold determination. The threshold determination will be for both cities. The proposed project requires other permits from both the cities of Kent and Tukwila and each individual city will remain responsible for these other permits. Projects applied for include: Shoreline Permit, City of Tukwila Shoreline Permit, City of Kent Other known required permits include: HPA, Washington State Department of Fish and Wildlife Public Works Permit, City of Tukwila Public Works Permit, City of Kent Studies required with the applications include: None. FILES AVAILABLE FOR PUBLIC REVIEW The application is available for review at the City of Tukwila, Department of Community Development (DCD), located at 6300 Southcenter Blvd #100. OPPORTUNITY FOR PUBLIC COMMENT 1 Your written comments on the project are requested. They must be delivered to DCD at 6300 Southcenter Blvd, Suite 100; Tukwila, WA, 98188 or postmarked no later than 5:00 P.M. on July 14, 2013. Comments may also be emailed to Brandon.Miles@Tukwilawa.gov. Tukwila has reviewed the project for probable adverse environmental impacts and expects to issue a determination of non -significance (DNS). The optional DNS process in WAC 197-11-35 is being used. There will be a single integrated comment period for the land use permits and the environmental review so this may be your only opportunity to comment on the environmental impacts of the project. If timely comments do not identify probable significant adverse impacts that were not considered by the anticipated determination the DNS will be issued without a second comment period. APPEALS You may request a copy of any decision, information on hearings, and your appeal rights by calling DCD at (206) 431-3670. For further information on this proposal, contact Brandon Miles at (206) 431-3684, Brandon.Miles@tukwilawa.gov or visit our offices at 6300 Southcenter Boulevard, Suite #100, Monday through Friday, 8:30 a.m: to 5:00 p.m. Application Filed: May 22, 2013.

CenturyLink installed a temporary aerial crossing due to the potential risk of flood waters released by Howard Hanson Dam damaging the fiber optic cables in conduit attached to the roadway bridge at South 180th Street. The permit for the temporary aerial crossing was conditioned for removal within three years of construction. Therefore, CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, adjacent to South 200th Street right-of-way to connect the existing underground fiber optic cables on the east and west sides of the Green River. The crossing will be done through a horizontal direction drill (HDD) technique. The eastern portion of the project from the mid -channel of the Green River is located within the City of Kent. The western portion of the project from the mid -channel of the Green River is within the City of Tukwila. The HDD portion of the crossing will be approximately 700 feet long and extend approximately 30 feet below the riverbed. A 12 -inch -diameter casing and four, 4 -inch -diameter conduits will be pulled through the bore. The project will include excavating a 20 -foot -long by 8 -foot -wide by 4 - foot -deep pit to launch the HDD from the west side of Green River and excavating a 20 -foot - long by 8 -foot -wide by 4 -foot -deep pit on the east side of Green River to pullback the conduits. Work within City of Tukwila An approximately 900 -foot -long, 2 -foot -wide open -cut trench will connect the cable from the launching pit to the existing Manhole 928 within the South 200th Street right-of-way and the undeveloped, private parcel (5201 South 200th Street, Parcel No. 022204-9015). The launch site will require disturbing approximately 10,000 square feet and a 12 -foot -long, 6 -foot -wide, 8 - foot -deep vault will be installed at the launch point. There is an existing gravel access road to the project area. The contractor staging will be located on the private parcel through obtaining a temporary construction easement. Upon completion of construction the site will be restored to the current condition as a vacant site prepared for future development. Work within City of Kent The project will be located within the Three Friend's Fishing Hole community park. The conduits will terminate at a new 6 -foot by 12 -foot by 13 -foot deep precast concrete vault. The vault will be set over the top of an existing CenturyLink duct bank at the corner of South 200th Street and 58th Place SE. The casing pipe and conduits will be pulled into the bore which will require stringing the pipe along South 196th and closing 58th Place SE for a short period of time. Upon completion of construction, the excavations will be backfilled and the site will be restored to the current condition as a public park. Schedule Construction of the project is anticipated to be approximately 2 months. CenturyLink South 200th Street Green River Crossing Shoreline Substantial Development Permit Project Valuation Documentation 'rd' CenturyLink- The portion of the boring within the City of Tukwila Shoreline Jurisdiction is approximately 470 feet long. The project costs are estimated at approximately $160 per lineal foot. Therefore, the project valuation is approximately $75,200 for the portion of the project within the Shoreline Jurisdiction. CenturyLink South 200th Street Green River Crossing Shoreline Substantial Development Permit Shoreline Master Program Criteria for Approval • 4r Po- i; CenturyLink- 140) Goals oi;CenturyLink- Goals and Policies Attachment A to Ordinance 2344 Chapter 6 of the Shoreline Master Program The City of Tukwila Shoreline Master Program (SMP) was updated in October 2011 in conformance with the Shoreline Management Act. The updated SMP includes shoreline goals and policies from. the 1995 City of Tukwila Comprehensive Plan. Projects located within the shoreline shall be consistent with the goals and policies identified in the SMP. 6.1 Shoreline Environment Designations, Comprehensive Plan Goal 5.1 The Shoreline Environment Designation for the project site is Urban Conservancy. The project is consistent with Policy 5.1.2, Urban Conservancy Environment. The project includes boring under the Green River using a horizontal directional drill (HDD) technique and installing four new fiber optic cables. The project would not impact vegetation within the Shoreline Jurisdiction and would preserve the existing ecological functions of the shoreline. As the project is located underground, there will not be impacts to public access or view restrictions. 6.2 Shoreline Planning and Management, Comprehensive Plan Goal 5.2 The project will be located underground and 30 feet below the riverbed within the Shoreline Jurisdiction. Therefore, the WRIA 9 Salmon Habitat Plan, Tukwila SMP Restoration Plan, and King County Flood Hazard Management Plan will not be impacted by the project. 6.3 Land Development Use and Economic Vitality, Comprehensive Plan Goal 5.3 CenturyLink installed a temporary aerial fiber optic crossing of the Green River at South 181st Street in 2011. The temporary crossing was installed due to the potential risk of flood waters released by Howard Hansen Dam damaging the fiber optic cables in conduit attached to the roadway bridge at South 180th Street. The temporary crossing was conditioned to be removed within three years of construction completion. These cables are critical to maintaining the vital communication facilities between the Kent O'Brien Central Office and the Tukwila Cyber Center. Therefore, this project will support the economic vitality of Tukwila by providing consistent communication services. The fiber optic cables will be buried 30 feet below the riverbed using an HDD technique. Using the HDD technique, adverse impacts to the shoreline environment are not anticipated and will not diminish the commercial navigability of the Green River. 6.4 Private Property Rights, Comprehensive Plan Goal 5.4 A private easement has been obtained for access through private property. Additionally, a permanent, 10 -feet -wide easement has been obtained for maintenance of the fiber optic cable. The project will be located entirely underground and will not affect public access and enjoyment of the shoreline. 6.5 Shoreline Design Quality, Comprehensive Plan Goal 5.5 The project is located entirely underground and will not impact future development. Therefore, the project will•retain the potential for high quality development and public activities in the City of Tukwila. 6.6 Access and Recreational Use, Comprehensive Plan Goal 5.6 The project is located entirely underground and will retain the existing opportunities for public recreation and access. CenturyLink - 1 - South 200th Street Green River Crossing • 1! 6.7 Transportation within the Shoreline Jurisdiction, Comprehensive Plan Goal 5.7 The project is located entirely underground and will not provide additional amenities for pedestrians, cyclists and users of public transportation. During construction, there may be a temporary increase in the amount of construction vehicles accessing South 200th Street. However, the river's navigability will be maintained during construction 6.8 Historical Resource Use and Archaeological Protection, Comprehensive Plan Goal 5.8 Historical resources have not been identified on the project site. The project will be constructed with the following condition provided by the Department of Archeology and Historic Preservation (DAHP): "If ground disturbing activities encounter human skeletal remains during the course of construction, then all activity will cease that may cause further disturbance to those remains. The area of the find will be secured and protected from further disturbance. The finding of human skeletal remains will be reported to the county medical examiner/coroner and local law enforcement in the most expeditious manner possible. The remains will not be touched, moved, or further disturbed. The county medical examiner/coroner will assume jurisdiction over the human skeletal remains and make a determination of whether those remains are forensic or non - forensic. If the county medical examiner/coroner determines the remains are non -forensic, then they will report that finding to the Department of Archaeology and Historic Preservation (DAHP) who will then take jurisdiction over the remains. The DAHP will notify any appropriate cemeteries and all affected tribes of the find. The State Physical Anthropologist will make a determination of whether the remains are Indian or Non -Indian and report that finding to any appropriate cemeteries and the affected tribes. The DAHP will then handle all consultation with the affected parties as to the future preservation, excavation, and disposition of the remains." 6.9 Natural Environment and Habitat Use, Comprehensive Plan Goal 5.9 The HDD will be launched west of the Shoreline Jurisdiction and vegetation within the Shoreline Jurisdiction will not be disturbed for the installation of the fiber optic cables. Therefore, it is anticipated, there will be no net loss of shoreline function as a result of the project. 6.10 Water Quality, Surface Water and Flood Control Use, Comprehensive Plan Goal 5.10 The clearing and grading for the project will occur west of the Shoreline Jurisdiction. Best Management Practices (BMPs) for erosion and sediment control will be implemented during all phases of construction. The bore will be located under the existing levee and is not anticipated to impact the levee structure. Therefore, the project is not anticipated to impact water quality, surface water or flood control use. 6.11 Public Health, Safety and Welfare, Comprehensive Plan Goal 5.11 The project would protect the community's public health, safety and welfare through ensuring communication connections are secure underground and below the river. 6.12 Shoreline Use Preferences, New Comprehensive Plan Goal 5.12 The project is located entirely underground within the Shoreline Jurisdiction and is consistent the goals of the Shoreline Management Act. The Shoreline Jurisdiction will not be impacted by the project and the uses will remain the same upon completion of the project.

The cables are critical to maintaining the vital communication facilities between the Kent O'Brien Central Office and the Tukwila Cyber Center. The crossing, performed under Public Works Permit No. PW 11-050 and Shoreline Permit L11-031, was conditioned to be removed within three years of construction completion. Therefore, CenturyLink is proposing a permanent buried fiber optic crossing of the. Green River, adjacent to South 200th Street right-of-way, to connect the existing underground fiber optic cables on the east and west sides of the Green River. The project includes a horizontal direction drill (HDD) under the Green River starting at private property (5201 South 200th Street) within the City of Tukwila and ending within the Three Friend's Fishing Hole Community Park in the City of Kent (see Vicinity Map). A 12 -inch casing and four, approximately 4 -inch -diameter conduits will be pulled through the bore and trenching will connect the conduits to existing manholes on each end of the project. Fiber optic cables will be pulled to complete the communications link. The boring will occur under the levees located on either side of the Green River. Contractor staging will be located within the City of Tukwila at 5201 South 200th Street. The majority of the facility will be located within a private easement; however a small portion will be within the South 200th Street right-of-way.

CPL Page 11 of 14 W:\\Long Range Projects\Shoreline\New Shoreline Permits\4-11-12 SSDP 09/13/2012 10:15 AM NO NET LOSS CHECKLIST What is No Net Loss? The Washington State Shoreline Management Act (SMA) requires protection of the natural resources and ecological functions of the shoreline environment. Ecological functions are processes that characterize the river and its shoreline and form habitats for water- and land-based wildlife and vegetation. Ecological processes depend on the geology, soil type, topography, climate, and other physical characteristics in the region. In the Green/Duwamish River watershed, key ecological processes include: • river flows, tidal fluctuations and saltwater influences; • creation, transport and deposition of sediment (for example scouring of soils, and erosion and formation of mud -flats or beaches); • transport of nutrients (from decomposition of plants and other organic materials); • provision of woody debris from fallen limbs and trees along the banks or in the water (the trunks and branches help form pools for fish); and • water quality (such as vegetation that can help to filter out pollutants that are washed into the river from parking lots and vegetation that can help reduce temperatures in the river, important for fish, especially salmon). These physical and biological processes comprise the ecological functions of the shoreline. The state guidelines that implement the SMA, adopted in 2003, establish the standard of "no net loss" of shoreline ecological functions for land uses and development within the shoreline jurisdiction. The No Net Loss standard is designed to stop the introduction of new negative impacts to shoreline ecological functions resulting from new development. Tukwila's Shoreline Master Program (SMP) defines no net loss as a: "...standard intended to ensure that shoreline development or uses, whether permitted or exempt, are located and designed to avoid loss or degradation of shoreline ecological functions that are necessary to sustain shoreline natural resources." In other words, the existing conditions of the shoreline ecological functions should not deteriorate due to new permitted development or new land use. A loss of ecological function can occur when a physical condition such as vegetation along the shoreline is removed or when habitat is altered through the construction of a dock or pier or other structures over this habitat. In order to maintain shoreline ecological functions, negative impacts must be mitigated to restore an equivalent amount of ecological function. The approach to mitigation must follow the mitigation sequencing steps adopted in the SMP (see next page). It should be noted that the SMA and the City's SMP also require improvement of shoreline functions, and therefore, some re -vegetation of the shoreline will be required in proportion to the scale of the project, regardless of whether there is a net loss to ecological functions. CPL Page 13 of 14 W:\\Long Range Projects\Shoreline\New Shoreline Permits\4-11-12 SSDP 09/13/2012 10:15 AM On a separate sheet of paper, please respond to the following questions to evaluate your project's impacts and assist in analyzing whether there will be a net loss to shoreline ecological functions requiring mitigation: 1. Describe the existing condition of the shoreline area and riverbank. For example, what plants and how much vegetation currently exist within the 200 foot shoreline jurisdiction; what is the condition of the shoreline (how steep are the banks, is there any erosion or slope failure, what are the soils like); is there "hard armoring" on the riverbank (for example, concrete or wooden bulkheads, metal sheet piling, rip -rap [rocks or concrete/asphalt blocks]), is there paving or are there any structures within the 200 ft. shoreline jurisdiction; are there any docks, piers, decks or other structures near or over the water; are there any above -ground or below ground utilities; etc.? 2. How will your project change the existing condition of the shoreline described above? 3. Please respond to the questions in the following chart - A No Net Loss analysis (prepared by a qualified biologist) must be prepared if the response to any of the questions in the chart below is "yes": 4. The way to achieve no net loss of ecological function is to mitigate the loss through one or a combination of the mitigation sequencing steps identified below. If preparing a No Net Loss analysis, please discuss how your project addresses the following mitigation sequencing steps (TMC 18.44.070 H.3.): a. Avoiding the impact altogether by not taking a certain action or parts of an action; b. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts; c. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment; d. Reducing or eliminating the impact over time by preservation and maintenance operations; e. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments; and f. Monitoring the impact and the compensation projects and taking appropriate corrective measures.

These cables are vital to CenturyLink's system as they contain circuits that are of an extremely sensitive nature affecting National Security, Local and Interstate Commerce, Local and Regional Emergency Readiness, and Local, Regional and National Telecommunications. In 2011, CenturyLink obtained permits from the City of Tukwila and the City of Kent to construct a temporary, single -span aerial fiber optic crossing of the Green River. CenturyLink installed a temporary aerial crossing due to the potential risk of flood waters released by Howard Hanson Dam damaging the fiber optic cables in conduit attached to the roadway bridge at South 180th Street. The permit for the temporary aerial crossing was conditioned for removal within three years of construction. Therefore, CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, adjacent to South 200th Street right-of-way, to connect the existing underground fiber optic cables on the east and west sides of the Green River. The crossing will be done through a horizontal direction drill (HDD) technique. The eastern portion of the project from the mid -channel of the Green River is located within the City of Kent. The western portion of the project from the mid -channel of the Green River is within the City of Tukwila. This memorandum provides information on the existing conditions and potential project impacts to streams, wetlands, fish and wildlife, and trees within the project area. Project Location and Description The project is located in portions of the City of Tukwila and the City of Kent (Section 2, Township 22 North, Range 4 East), and is shown in Figure 1. The HDD portion of the crossing will be approximately 700 feet long and will be constructed approximately 30 feet below the riverbed. A 12 -inch HDPE casing and four, 4 - inch -diameter conduits will be pulled through the bore and trenching will connect the conduits to existing manholes on each end of the project. The project will include excavating a 20 -foot -long by 8 -foot -wide by 4 -foot -deep pit to launch the HDD from the CenturyLink — South 200th Street Green River Crossing May 2013 Environmental Assessment 1 HR west side of Green River and excavating a 20 -foot -long by 8 -foot -wide by 4 -foot -deep pit on the east side of Green River to pullback the conduits and casing. Work within City of Tukwila An approximately 900 -foot -long, 2 -foot -wide open -cut trench will connect the cable from the launching pit to the existing Manhole 928 within the South 200th Street right-of-way and the undeveloped, private parcel (5201 South 200th Street, Parcel No. 022204-9015). The launch site will require disturbing approximately 10,000 square feet and a 12 -foot - long, 6foot-wide, 8 -foot -deep vault will be installed at the launch point. There is an existing .gravel access road to the project area. The contractor staging will be located on the private parcel through obtaining a temporary construction easement. Upon completion of construction the site will be restored to the current condition as a vacant site prepared for future development. Work within City of Kent The eastern terminus of the project will be located within the Three Friend's Fishing Hole Community Park. The HDD will terminate at a new 6 -foot by 12 -foot by 13—foot deep precast concrete vault. The vault will be set over the top of an existing CenturyLink duct bank at the corner of South 200th Street and 58th Place SE. The casing pipe and conduits will be pulled into the bore which will require stringing the pipe along South 196th and closing 58th Place SE for a short period of time. Upon completion of construction, the excavations will be backfilled and the site will be restored to the current condition as a public park. 2.0 Methods The field investigation included two steps. The first step was a review of existing documents such as federal and state agency species lists, City and King County wetland and stream inventories, wetland and stream reports for adjacent properties, and other environmental documents. The second step was a field investigation of the site. Document Review The following existing documents were reviewed prior to beginning the field work: • Soil Survey of King County Area, Washington (Snyder et al. 1973) • National Wetland Inventory maps (http://www.fws.qov/wetlands/data/Mapper.html - accessed 2/26/2013) • King County GIS (IMAP http://www.kingcountv.gov/operations/GIS/Maps/iMAP.aspx — accessed 2/26/2013) • City of Kent Wetland Map (http://www.ci.kent.wa.us/publicworks/maps.aspx - accessed 2/26/2013) • USGS Washington Streamflow Data (http://waterdata.usgs.gov/WA/nwis/current/?type=flow — accessed 2/26/2013) • Habitat limiting Factors and Reconnaissance Assessment Report, Green/Duwamish and Central Puget Sound watersheds (WRIA 9 and Vashon Island) (Kerwin and Nelson 2000) • Washington Sate Department of Fish and Wildlife (WDFW) Priority Habitats and Species database (http://wdfw.wa.gov/mapping/qhs/), accessed 2/26/2013 • WDFW SalmonScape http://wdfw.wa.qov/mappinq/salmonscape/index.html - accessed 2/26/2013 • City of Tukwila Shoreline Master Program. (City of Tukwila 2011) CenturyLink — South 200th Street Green River Crossing Environmental Assessment May 2013 2 • City of Kent Shoreline Master Program (City of Kent 2009) Field Methods An HDR biologist conducted a site visit on February 27, 2013. The field investigation included the identification of streams and wetlands in the project area, but no formal delineation of wetland (not present) or Ordinary High Water Marks (OHWMs), since sufficient survey data is already present for the Green River OHWM. The study area extended approximately 100 feet south from 200th Street from the proposed cable alignment. All trees greater than 6 -inches in diameter at breast height and woody shrubs located within the immediate vicinity of the proposed cable alignment location were located using a Trimble GeoXT 2005 handheld GPS receiver and field personnel documented the dripline for each identified tree and made notes on the general health of trees within the limits of utility footprint. The dripline was determined by measuring the greatest distance to the outer edge of the crown. Trees were visually surveyed for decay, damage, or decline (see Figure 2). Site photographs were taken to document existing site conditions. 3.0 FIncHngs Streams The Green River is the only water body in the project area. The proposed project is located at approximately river mile (RM) 16.75. Cities of Tukwila and Kent classify the Green River as a Type 1 stream, which are inventoried as a Shoreline of the State. Both cities regulate Type 1 streams under their Shoreline Master Program. Table 1 summarizes local ratings and shoreline jurisdictions of the Green River for the cities of Tukwila and Kent. Table 1. Summary of Local Regulations of the Green River in the Project Area Stream Tributaryto Jurisdiction Local Ratin ga Shoreline Designation" Width' Green River Duwamish Waterway Tukwila Type 1 Urban Conservancy 125 feet Kent Type 1 Urban Conservancy Open Space 200 feet a City of Tukwila Municipal Code 18.44 and 18.45.10; City of Kent Municipal Code 11.04 and 11.06 b City of Tukwila Shoreline Master Program (2011) ; City of Kent Shoreline Master Program: Ordinance No.3931 (2009) The Green River is located within the Green/Duwamish River Watershed (Water Resource Inventory Area [WRIA] 9), and the Green/Duwamish River basin encompasses approximately 566 square miles. The Green River originates in the Cascade Mountains and flows northwesterly for approximately 93 miles before draining into the Duwamish Waterway and Elliott Bay (Kerwin and Nelson 2000). Within the project area, the Green River flows south to north. Levees are present along both banks of the Green River at the proposed communication line crossing location. These levees were constructed in the early 1900s and have been maintained by the Green River Flood Control Zone District (City of Kent 2009). On west side of the bank, the Green River regional trail is located on top of the levee and runs along the Green River. In an effort to help preventing flooding in the Green River valley, the City of Tukwila CenturyLink — South 200th Street Green River Crossing Environmental Assessment May 2013 3 has placed sandbags on top of the levee of the west bank (City of Tukwila 2009). These sandbags have been removed. The banks of the Green River in this reach are generally steep but natural outside of the South 200th Street bridge footprint. Dominant species observed in the study area include Himalayan blackberry (Rubus armeniacus), Sitka willow (Salix sitchensis), Pacific willow (Salix lasiandra), and reed canarygrass (Phalaris arundinacea). Dominant tree species include planted spruce (Picea sitchensis) and Douglas fir (Pseudotsuga menziesii), volunteer red alder (Alnus rubra), and black cottonwood (Populus balsamifera). The east side of the channel is similarly dominated by willow shrubs, with dense thickets of Himalayan blackberry and a few scattered Japanese knotweed (Polygonum cuspidatum). There appears to have been stream restoration work in this reach, as several pieces of large woody debris have been placed in the east side of the channel and native riparian shrub (dogwood, Cornus alba) and tree species (Douglas fir) have been interplanted along the stream bank. Wetlands Two wetlands were identified in the project vicinity in the priority habitat and species map and City of Kent Wetland map. One wetland is mapped south of 200th Street on the west bank of the Green River, and a smaller wetland is mapped on the east bank. However, substantial development has taken place in the area since this mapping was completed. The area to the south of South 200th Street and west of the Green River has been extensively graded, and the area to the east (at Russell Road South) consists of landscaped lawn, with a few ornamental trees. Natural vegetation in the project area is limited to the banks of the Greek River. No wetlands were identified in the project area during the field investigation. Fish and Wildlife The cities of Tukwila and Kent have both designated the Green River as Fish and Wildlife Habitat Conservation Areas (FHWCAs) because the Green River provides habitat for salmonid species that are listed as threatened species under the Endangered Species Act. The Green River is documented to support eight anadromous fish species, including Chinook salmon (Oncorhynchus tshawytscha), steelhead trout (0. mykiss), coho salmon (0. kisutch), sockeye salmon (0. nerka), chum salmon (0. keta), pink salmon (0. gorbuscha), coastal cutthroat (0. clarki clarki), and bull trout (Salvelinus confluentus) (WDFW 2010a; WDFW 2013; Kerwin and Nelson 2000). Out of eight species, Chinook salmon, steelhead trout, and bull trout are listed as threatened species. In addition, resident population of coastal cutthroat trout is also reported to occur in the Green River (Kerwin and Nelson 2000). Although there is a continuing effort of restoring the riparian condition of the Green River in the project vicinity, suitable spawning habitat is likely absent at this reach. Presence of these species is limited to migration and rearing at the proposed project location (WDFW 2010b; Kerwin and Nelson 2000). According to the WDFW Priority Habitats and Species database (WDFW 2010a), two osprey (Pandion haqliaetus) nests have been identified in the vicinity of the project area (approximately % to one mile from the site). Osprey are a state monitor species, but are not federally listed and are not considered a priority species by Washington state. Osprey are pisciverous hawks, and may use the Green River in the project vicinity for foraging. Waterfowl concentrations are also mapped in the immediate proximity of the project (immediately south of South 200th Avenue), however, this are has been extensively CenturyLink - South 200th Street Green River Crossing Environmental Assessment May 2013 4 Ian graded and currently has neither water nor vegetation that would support waterfowl concentrations. No other priority habitat species have been documented to occur in the project vicinity (WDFW 2013). Tree and Shrub Survey A total of 45 trees and shrubs were documented within the study area, 25 on the west side and 20 on the east side of the Green River. Tree species observed within the project study area include big -leaf maple, red alder, common hawthorn, Sitka spruce, black cottonwood, Douglas fir, various willows (Salix sp., unidentified), western red cedar, and several ornamental species. Table 2 presents the species, diameter at breast height (dbh), and condition of trees and shrubs observed. Locations of these trees are also shown in Figure 2.

The proposed project will remove some areas of mowed grasses and ornamental plants at the proposed underground cable and termination pole locations. These areas will be restored to the present condition upon completion of construction. Therefore, no impacts from the operation of the proposed communication line are anticipated. As a result, the proposed project will have no impacts on sensitive areas including wetlands, streams, and fish and wildlife habitat; therefore, no mitigation measures are proposed for this project. 5.0 References Kent, City of. 2009.

There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. In 2011, CenturyLink (formerly Qwest Communications) obtained permits from the City of Tukwila and the City of Kent to construct a temporary, single-span aerial fiber optic crossing of the Green River at 181st Street. CenturyLink installed a temporary aerial crossing due to the potential risk of flood waters released by Howard Hanson Dam damaging the fiber optic cables in conduit attached to the roadway bridge at South 180th Street. The permit for the temporary aerial crossing was conditioned for removal within three years of construction. Therefore, CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, adjacent to South 200th Street right-of-way to connect the existing underground fiber optic cables on the east and west sides of the Green River. The crossing will be done through a horizontal direction drill (HDD) technique and open -cut trench. The eastern portion of the project from the mid -channel of the Green River is located within the City of Kent. The western portion of the project from the mid -channel of the Green River is within the City of Tukwila. The HDD portion of the crossing will be approximately 700 feet long and extend approximately 30 feet below the riverbed. Approximately four 4 - inch -diameter conduits will be pulled under the Green River. The project will include excavating a 20 -foot -long by 8 -foot -wide by 4 -foot -deep pit to launch the HDD from the west side of Green River and excavating a 20 - foot -long by 8 -foot -wide by 4 -foot -deep pit on the east side of Green River to pullback the conduits. Within the City of Tukwila, an approximately 900 -foot -long, 2 -foot -wide open -cut trench will connect the cable from the launching pit to the existing Manhole 928 within the South 200th Street right-of-way and the undeveloped, private parcel (5201 South 200th Street, Parcel No. 022204- 9015). The launch site will require disturbing approximately 10,000 square feet and a 12 -foot -long, 6 -foot -wide, 8 -feet -deep vault will be installed at the launch point. There is an existing gravel access road to the project area. The contractor staging will be located on the private parcel through obtaining a temporary construction easement from the property owner. CenturyLink is currently working with the property owner to secure easements for the project. Upon completion of construction the site will be restored to the current condition as a vacant site prepared for future development. Within the City of Kent, the project will be located within the Three Friend's Fishing Hole community park. The conduits will terminate at a new 6 -foot by 12 -foot by 13—foot deep precast concrete vault. The vault will be set over the top of an existing CenturyLink duct bank at the corner of S. 200 Street and 58th Place SE. Upon completion of construction, the excavations will be backfilled and the site will be restored to the current condition as a public park. SEPA Checklist Agency Comments Page 2 SEPA Checklist Please respond to all questions. Use separate sheets as necessary. Applicant Responses: 11. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, the tax lot number, and section, township, and range. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project would extend from an existing Manhole (Manhole 928) within the South 200th Street right-of-way. The fiber optic cable would be launched from 5201 South 200th Street (Parcel 022204-9015) under the Green River, and be pulled from the Three Friends Fishing Hole Community Park within the City of Kent right-of-way. See design drawings. 12. Does the proposal lie within an area designated on the City's Comprehensive Land Use Policy Plan Map as environmentally sensitive? The western portion of the project is located within the Tukwila South Overlay District and not within an area designated as environmentally sensitive. The eastern portion of the project is located within an area designated as Parks and Open Space within the City of Kent Comprehensive Plan and not within an area designated as environmentally sensitive. Agency Comments t, 61/4tetvv'm f i� gtry,,,� fiL Page 3 Please respond to all questions. Use separate sheets as necessary. Applicant Responses: B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other: The project site has been graded to a generally flat grade in preparation for future development. The project site is intersected by the Green River. The portion of the project within the City of Kent is generally flat and slopes down gradient to the Green River. There is a rolling hill within the Three Friends Fishing Hole Community Park that is a portion of the levee. b. What is the steepest slope on the site (approximate percent slope)? The banks of the Green River range from 35% to 50% slopes within the project area. The rest of the project site is generally flat with slopes no greater than 5%. Any earthwork will be done in areas where the slope is less than 5%. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. According to the Natural Resources Conservation Services (NRCS), the project site consists of Alderwood and Kitsap soils, Everett gravelly sandy loam, Newberg silt loam, Nooksack silt loam, Renton silt loam, Snohomish silt loam, and Urban land. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There are no known surface indications or history of unstable soils in the immediate vicinity. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. The portion of the project within the City of Tukwila would require approximately 290 cubic yards of excavation and approximately 74 cubic yards of fill for the open -cut trench along the South 200th Street right-of- way, the HDD launch site, and the HDD crossing alignment. The portion of the project located within the City of Kent would require approximately 134 cubic yards of excavation and approximately 110 cubic yards of fill for the open -cut trench within the Three Friends Fishing Hole Community Park, the HDD receiving site, HDD crossing alignment, and the vault entrance and penetration site. The contractor would determine the source of the fill material. SEPA Checklist Agency Comments Page 4 1111111 SEPA Checklist Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. There would be a potential for erosion to occur during construction of the open -cut trenches, HDD launch site, and HDD receiving site. Erosion could occur during installation and removal of erosion and sediment control structures, trench excavation, conduit installation, soil stockpiles, truck traffic, final grading prior to restoration, and other construction activities. Soils temporarily exposed during construction could be eroded by stormwater. Standard erosion control measures would be implemented to mitigate these potential impacts. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project would include buried fiber optic cables and would not increase the amount of impervious surface on the portion of the project within the City of Tukwila. A temporary staging area would be constructed to launch the directional bore under the river. Upon completion of construction, the staging area would be removed and restored to the current condition. A 6 -foot -wide by 10 -feet -long vault would be installed within the portion of the project located in the City of Kent. The vault would be accessed by a 3 - foot -diameter vault lid. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Erosion and sediment control (ESC) for the project would rely on structural measures (e.g. silt fences, straw bale barriers, and plastic covering) and non-structural measures (e.g. common-sense planning, good design, routine inspection and maintenance, employment and enforcement of non -ESC Best Management Practices). Once permanent erosion control is in place (revegetating or paving), no other erosion control measures would be required. 2. Air a. What types of emissions to the air would result from the proposal (for example, dust, automobile odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Temporary air quality impacts may occur during construction due to fugitive dust emissions caused by clearing, excavation, uncovered stockpiles, and any other construction. Fugitive dust has the potential to be of greater concern during dry, warm weather conditions when wind and construction equipment create more dust. Localized increases in exhaust emissions from equipment and vehicle operation would occur during construction; however, emissions would not likely be great enough to noticeably affect air quality. Page 5 OS N SEPA Checklist , Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments The operation and maintenance of the crossing may require periodic use of equipment and vehicles; however, emissions would not likely be great enough to noticeably affect air quality. b. Are there any off-site sources of emissions or odor that may affect your proposal. If so, generally describe. There are no known off-site sources of emissions or odor that would affect the project. c. Proposed measures to reduce or control emissions or other impacts to air, if any: The Puget Sound Clean Air Agency (PSCAA) governs activities affecting air quality in King County. The project would be constructed in compliance with the PSCAA requirements. Fugitive dust impacts associated with construction of the proposed project are not anticipated to be significant. Construction contractors would comply with the regulatory requirements and implement appropriate mitigating measures as necessary. Vehicular emissions associated with construction would be short term in nature. The completed project would not produce emissions. 3. Water a. Surface: 1. Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The Green River intersects the project site. The Green River turns into the Duwamish Waterway and flows into Puget Sound. The City of Tukwila and City of Kent sensitive area maps indicate there are no potential wetland areas in the vicinity of the project. 2. Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. CenturyLink is proposing a permanent buried fiber optic crossing of the Green River, connecting the existing underground fiber optic cables on the east and west sides of the Green River. The crossing would be done through a horizontal direction drill (HDD) technique. The eastern portion of the project from the mid -channel of the Green River would be located within the City of Kent. The western portion of the project from the mid -channel of the Green River would be within the City of Tukwila. The HDD portion of the crossing would be approximately 700 feet long and extend approximately 30 feet below the riverbed. Approximately four 4 -inch -diameter conduits would be pulled through the bore. The Page 6 SEPA Checklist Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments launch and receiving sites for the HDD would be located outside the shoreline jurisdiction on both sides of the river (Tukwila on the west and Kent on the east). See the attached design drawings for the proposed project. 3. Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Fill and dredge material would not be placed within the surface waters or wetlands. 4. Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities, if known. The project would not require diversion or withdrawals of surface waters. 5. Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. The project would include boring 30 feet under the Green River using the HDD technique. According to the Federal Emergency Management Agency (FEMA) maps, a 100 -year floodplain is identified along the Green River. The HDD would require a launch site and receiving site. These sites would be located outside the 100 -year floodplain. As the project includes buried facilities, the project would not include surface clearing and grading within the 100 -year floodplain. See the attached design drawings showing the 100 -year floodplain. 6. Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. The project would not involve discharges of waste materials to surface waters. b. Ground: 1. Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities, if known. The project would not include withdrawing ground water and water would not be discharged to ground water. Page 7 OS N SEPA Checklist • Please respond to all questions. Use separate sheets as necessary. Applicant Responses: Agency Comments" 2. Describe waste materials that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve: The project would not discharge waste materials into the ground. c. Water Runoff (including storm water): 1. Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow? Will this water flow into other waters? If so, describe. The source of runoff during construction would be precipitation. If needed, runoff would likely be collected, treated, and disposed of using culverts, ditching, or pumping. Erosion control measures would be applied during construction as noted in B.1.h. 2. Could waste materials enter ground or surface waters? If so, generally describe. Waste materials are not anticipated to enter the ground or surface waters during construction or operation of the proposed project. With the HDD bore technique, there is the potential for drilling mud to enter stream channel during the boring channel through fractured bedrock that is referred to as a "frac-out." d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Measures to reduce or control surface, ground, and runoff water may include the following: • Minimize area of disturbance to the amount necessary for construction and project features. • Stabilize exposed soils immediately following construction. • Implement erosion and sedimentation control (ESC) measures to address erosion control during construction.

SEEDING, MULCHING, PLASTIC COVERING, ETC.) 8. ANY AREA NEEDING ESC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION AS DETERMINED BY THE ENGINEER, SHALL BE ADDRESSED WITHIN SEVEN (7) DAYS. 9. THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN 24 HOURS FOLLOWING A STORM EVENT. 10. AT NO TIME SHALL MORE THAN ONE (1) FOOT OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT -LADEN WATER INTO THE DOWNSTREAM SYSTEM. 11. STABILIZED CONSTRUCTION ENTRANCES AND ROADS SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT. ADDITIONAL MEASURES, SUCH AS WASH PADS, MAY BE REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT CLEAN FOR THE DURATION OF THE PROJECT. 12. ANY PERMANENT RETENTION/DETENTION FACILITY USED AS A TEMPORARY SETTLING BASIN SHALL BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY. IF THE PERMANENT FACILITY IS TO FUNCTION ULTIMATELY AS AN INFILTRATION SYSTEM, THE TEMPORARY FACILITY MUST BE ROUGH GRADED SO THAT THE BOTTOM AND SIDES ARE AT LEAST THREE FEET ABOVE THE FINAL GRADE OF THE PERMANENT FACILITY. 13. WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE APPLIED AT A 2 -INCH MINIMUM THICKNESS. STRAW MULCH SHALL NOT BE USED IN WETLANDS OR WETLAND BUFFERS. 14. PRIOR TO THE BEGINNING OF THE WET SEASON (OCTOBER 1), ALL DISTURBED AREAS SHALL BE REVIEWED TO IDENTIFY WHICH ONES CAN BE SEEDED IN PREPARATION FOR THE WINTER RAINS. DISTURBED AREAS SHALL BE SEEDED WITHIN ONE WEEK OF THE BEGINNING OF THE WET SEASON. A MAP OF THOSE AREAS TO BE SEEDED AND THOSE AREAS TO REMAIN UNCOVERED SHALL BE SUBMITTED TO THE ENGINEER. THE ENGINEER CAN REQUIRE SEEDING OF ADDITIONAL AREAS IN ORDER TO PROTECT SURFACE WATERS, ADJACENT PROPERTIES, OR DRAINAGE FACILITIES. 15. ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE IN ACCORDANCE WITH EROSION AND SEDIMENT CONTROL STANDARDS IN APPENDIX D OF THE 1998 KING COUNTY SURFACE WATER DESIGN MANUAL. 16.
