List any government approvals or permits that will be needed for your proposal, if known. • City of Seattle – Shoreline Substantial Development/Master Use Permit • City of Seattle – building permit • Washington Department of Fish and Wildlife – Hydraulic Project Approval • US Army Corps of Engineers – Section 10/404 Permit 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. 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. (Lead agencies may modify this form to include additional specific information on project description.) The proposed temporary relocation of Seattle Fire Department Fire Station Number 5 to northeast Pier 90, Terminal 91, includes limited in-water and shoreline construction activities. At present, Fire Station Number Five provides essential water and land-based fire and emergency response services. The existing fire station site, at 925 Alaskan Way, includes moorage for two fire boats and a single rescue boat. The existing fire station site also houses fire truck and emergency response vehicles. Upland access to Fire Station Number Five will be impeded due to re-construction of the central waterfront seawall. Use of Terminal 91 as a fire and rescue boat moorage site for Fire Station Number Five during the period of seawall re-construction is proposed in order to ensure the required uninterrupted fire and emergency services provided by Fire Station Number Five. Please note that land-based emergency response vehicles will not be relocated to the Terminal 91 project site. The proposed temporary Fire Station Number Five relocation includes aquatic area and pier/upland actions at Pier 90, Terminal 91, necessary for the marine response, rescue, and emergency service provided by the fire department. Aquatic area structures: Installation of approximately 2000 square feet of concrete cell moorage float area is required for moorage of two Fire Station Number Five fire boats and a single rescue boat. Five 40 feet long, ten feet wide concrete cell floats will be installed, end-to-end, to form a 200 feet long fire station moorage. The moorage floats will be held in place with ten, 24 inch diameter cylindrical steel piling placed immediately water-ward of the existing creosote piling fender system at the northeast margin of Pier 90. Access from Pier 90 upland grade elevation to the fire boat moorage float will be provided by an L-shape metal grate surface gangway, approximately 145 feet long, mounted on the existing Pier 90 grade surface. The combined moorage float and gangway over-water area is approximately 2105 square feet. Upland structures: Temporary relocation of Fire Station Number Five to Pier 90, Terminal 91, requires installation of three pre-fabricated structures on existing upland area immediately adjacent to the fire boat and emergency vessel moorage and gangway structures. (1) A crew accommodation modular structure, approximately 1850 square feet, will provide personnel quarters and communications/office space. (2) A fire crew equipment storage structure, approximately 750 Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 3 of 29

square feet, will be located adjacent to the fire crew accommodation/office structure. (3) A third modular structure, approximately 1200 square feet, in the form of a metal frame tent-like enclosure, is required for additional storage of fire crew gear, equipment, and vehicles. Each of the modular structures will be served by appropriate access stairs and ramps. Each modular structure will be consistent with code requirements for insulation, heating/ventilation, and structure foundation tie-down/stability. The modular structures will require water, electrical and sanitary sewer service. Sewer and water service will include up to 50 linear feet of utility trench, approximately four feet wide and four feet in depth, totaling approximately 30 cubic yards of excavation and back-fill to match existing grade conditions. Electrical service is expected to include placement of at-grade conduit tubes. Relocation of fire boat rescue, and emergency vessels and equipment necessary for operation of Fire Station Number Five requires installation of new moorage float guide piling and pre- fabricated, concrete cell moorage floats adjacent to the northeast margin of the existing Pier 90, Terminal 91, cargo dock. As a result approximately 2105 square feet of new over-water structure area (over-water coverage) will be placed in existing sub-tidal aquatic area in the north end of the east slip at Terminal 91. Existing water depths at the proposed moorage float site are approximately minus 26 to 34 feet MLLW. It is proposed that negative aquatic area effects due to new sub-tidal over-water coverage will be off-set by improving existing exposed, un-vegetated rip-rap bank-line in northeast shoreline area in the Terminal 91 east slip. Bank-line improvements will include installing native riparian vegetation between elevation approximately plus 13 feet and 15 feet MLLW. Riparian planting will be placed in approximately 425 linear feet of existing rip-rap bank- line, accomplished through re-shaping the fractured stone armor bank-line to include a five to six feet wide riparian vegetation planting terrace. Establishing native riparian vegetation in the east slip will provide increased shoreline and inter-tidal aquatic area natural resource values, as compensation for the potential negative effects of new moorage float and piling over-water structures in sub-tidal aquatic area at the northwest margin of the east slip. Re-shaped bank-line and placement of native riparian vegetation will not require alteration or fill in existing east slip aquatic area. 12. 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, and section, township, range, if known. 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.

TO BE COMPLETED BY APPLICANT B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, and mountainous, other ______. The Pier 90, Terminal 91, project site is located in northeast Elliott Bay, in the City of Seattle. The area surrounding Terminal 91 is at the south end of a landscape feature referred to as Inter- Bay. Prior to urban development, the Inter-Bay location, the area separating the present-day City of Seattle neighborhoods of Queen Anne, to the east, and Magnolia, to the west, consisted of lowland and inter-tidal aquatic area, including approximately 600 acres of inter-tidal and marsh habitat. The present Inter-Bay area landform consists of filled upland, constructed in order to create comparatively level industrial area. The Inter-Bay area is approximately 1.5 miles long, measured north to south, between Fishermen’s Terminal, at Salmon Bay on the south margin of the Lake Washington Ship Canal, and Elliott Bay. The Inter-Bay industrial area is approximately 2000 to 3500 feet in width, with filled elevations approximately 16 to 33 feet above MLLW. Terminal 91, including approximately 215 acres, is the largest single property in the approximately 920 acre Ballard Inter-Bay North-end Manufacturing and Industrial Center (BINMIC, City of Seattle comprehensive plan designation). Terminal 91 upland area and Piers 90 and 91 consist entirely of filled former shoreline, inter-tidal, and sub-tidal aquatic area, with grade elevations plus 16 to 19 feet MLLW, constructed more than ninet decades ago for the purpose of marine industrial development. As a constructed, filled marine industrial site, upland slopes throughout Terminal 91 upland and pier locations are less than two percent. b. What is the steepest slope on the site (approximate percent slope)? The Terminal 91 marine industrial project area includes approximately 215 acres, consisting of approximately 143 acres upland area, approximately 17 acres over-water pier area, and approximately 55 acres exposed aquatic area. The steepest slopes at the project site are constructed armored shoreline areas adjacent to existing pier and vehicle access areas. Upland, pier, and navigational access areas at Terminal 91 are built and committed to marine industrial cargo and passenger transfer uses and activities. Existing Terminal 91 facilities include bulk cargo transshipment areas, cruise vessel berths and passenger service structures, seafood receiving, processing and cold storage buildings, fishing vessel moorage, fishing and marine equipment fabrication and vessel outfitting, barge and tugboat moorage and service areas, and upland import/export vehicle and equipment staging areas. A total of approximately 825,000 square feet of cargo storage, food processing/cold storage, and fishing/marine equipment fabrication/repair buildings are present at Terminal 91. Terminal 91 includes two piers: Pier 90 at the east side of the terminal and Pier 91 on the west margin of the facility. Each pier consists of a filled center portion connecting to filled upland Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 5 of 29

area at the north threshold of each pier. The west, south, and east perimeter of each pier includes concrete and treated wood piling supported dock area, approximately 80-85 feet wide, fitted with combined timber/steel pier fender piling. Pier 90 is approximately 2350 feet long (north to south) and includes approximately 4125 linear feet of deep draft vessel moorage. Pier 91 is approximately 2500 feet long, with 4425 linear feet of deep draft vessel moorage. Existing aquatic area conditions adjacent to berth and navigational access facilities at Terminal 91 include the following general areas: (1) inter-tidal (plus 13 to minus eight feet MLLW); (2) shallow sub-tidal (minus eight feet to minus 15 feet MLLW); and, (3) sub-tidal (minus 15 to 35 feet MLLW) area. These aquatic area locations consist of sand/mud substrate in lower elevations and sand/rocky areas in inter-tidal locations. Aquatic area slopes at Terminal 91 are variable. Sub-tidal moorage areas, between minus 15 and 35 feet MLLW, include approximately 39 acres, with existing flat or very gradual slopes, characteristic of dredged and maintained navigational access conditions. Shallow sub-tidal area, minus 15 feet to minus eight feet MLLW, representing the transition between deep draft navigational access areas and more exposed upper tidal elevations, includes approximately 2.8 acres, with 1:1 to 3:1 substrate slopes. Existing exposed inter-tidal aquatic area at Terminal 91, extending up-slope from minus eight feet to plus 13 feet MLLW, comprises approximately 13.2 acres, with substrate slopes between 3:1 and 8:1. Please note, an additional category of inter-tidal area at Terminal 91 includes structurally stabilized slope area beneath existing cargo piers. This inter- tidal slope area consists of riprap, slopes 1.75:1 to 2:1, totaling approximately 17 acres. 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. All existing upland area at the Terminal 91 project site consists of filled former shoreline, tideland, and aquatic area in north Elliott Bay. Fill at the site consists of sediments dredged from the previous tideland area, excavated in the first two decades of the last century in order to create deep draft navigational access, and more recently placed fill materials from adjacent upland locations. The Terminal 91 project site, including Pier 90, consists entirely of filled upland and has no previous, existing, or potential agricultural use. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. As a filled former aquatic area site, the Terminal 91 project site is subject to liquefaction and is identified by City of Seattle Critical Area maps as within a liquefaction zone. Liquefaction potential zones are considered environmentally sensitive but not environmentally critical areas. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. No dredging or filling of existing aquatic area is proposed. The proposed Fire Station Number Five project will entail placement of ten steel piling, followed by approximately 2105 square feet of new over-water moorage and gangway structure, with no filling or grading proposed. Please note that installation of structures and associated new over-water structure area will require measures intended to compensate for potential negative effects to existing sub-tidal aquatic area. The proposed project includes re-shaping approximately 425 linear feet of existing rip-rap bank- Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 6 of 29

line to create approximately 2125 square feet of new native riparian vegetation area. The proposed bank-line re-shaping and planting will be limited to retro-fit of existing rip-rap armored shoreline above approximately plus 13 to 15 feet MLLW. No new stone armor will be placed. Up to 110 cubic yards of combined sand and soil will be placed in the riparian vegetation terrace area shaped by retro-fitting the existing armored bank-line. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. No erosion due to the proposed project, in existing upland area or adjacent aquatic area, is anticipated. Guide piling and moorage installation will not result in erosion conditions. Re- shaping existing rip-rap armor bank-line above approximately plus 13 feet MLLLW will not de- stabilize the existing structurally stabilized slope. Please note that successful establishment of approximately 2125 square feet of native riparian vegetation is expected to contribute to long- term bank-line stability. The bank-line improvement area is located at the northeast margin of the east slip at Terminal 91, approximately 400-450 linear feet northeast of the proposed moorage float location, and approximately 2500 linear feet north of the south end of Pier 90, at the margin of open water in Elliott Bay. As a result the proposed riparian planting area is protected from wind generated waves and vessel wakes and will not be subject to erosion. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The proposed fire station relocation project will alter existing impervious surface, as necessary for water and sewer utility trenching. Existing pavement and grade elevations will be restored following back-fill of utility trench excavation areas. No new impervious surface is proposed. h. Proposed measures to reduce or control erosion, or other impacts to the earth if any: Installation of steel piling and moorage floats necessary for relocation of Fire Station Number Five does not include activities with the potential for creating fugitive sediments or shoreline erosion. Upland utility trenching and bank-line improvements proposed off-setting potential sub- tidal water column effects due to new over-water structures will be accomplished using best management practices for control of potential sources of erosion. Upland utility trenching activities will be protected from release of disruptive sediments through use of temporary straw bales and application of erosion control plant-fiber mats. Actions necessary for re-shaping approximately 425 linear feet of existing rip-rap armor bank-line, with construction between approximately plus 13 to 15 feet MLLW, will be isolated with a floating debris boom and top-of- bank areas will be fitted with temporary silt fences. All exposed soil surfaces will be protected from storm water-related sediment disruption through use of temporary straw bales and re-graded slopes will be stabilized by application of erosion control, plant-fiber mats and formed plant material logs. Finally, all re-shaped bank line areas will receive native riparian vegetation as long- term soil stabilization measures. Project utility trenching and rip-rap bank-line improvements will be implemented consistent with the City of Seattle Storm Water, Grading, and Drainage Control Ordinance and Department of Planning and Development Director’s Rule 6-93. A temporary erosion and sediment control plan will be prepared for utility trench work and re-shaping existing rip-rap slope areas.

2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. The proposed activity is limited to the following construction activities: (1) installation of ten steel guide piling; (2) installation of five pre-fabricated concrete cell moorage floats; (3) placement of three modular structures in existing upland area; and, (4) re-shaping approximately 425 linear feet of existing rip-rap armored bank-line to receive native riparian vegetation. Air emissions are expected from vehicles and equipment used during moorage float construction, modular building installation, and bank-line improvements. Equipment anticipated for use at the site will include motor-powered construction machinery and heavy trucks. Please note that air emissions anticipated from the completed fire station relocation site will be limited to fire boat, fire department vehicles, and fire department personnel vehicles. Air emissions from the finished fire station relocation site are not expected to change substantially compared with past activities at Terminal 91 or fire department activities at the present Fire Station Number Five site. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. No off-site sources of air emissions are present that have the potential to adversely affect the present proposal. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Motor-powered equipment used for the proposed construction activities and subsequent operation of the relocated Fire Station Number Five will be operated and maintained consistent with existing air emissions requirements. 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 proposed project site, Terminal 91 is located on the north shoreline of Elliott Bay. The aquatic environment is marine. Elliott Bay, a deep marine water feature, includes approximately 1300 acres. The west margin of Elliott Bay is approximately 2.7 miles wide in the area between the bay and Admiralty Inlet in Puget Sound. 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. The proposed project will take place in existing shoreline area. Activities necessary for placement of moorage piling, moorage floats, upland modular buildings, and re-shaping of existing rip-rap armored bank-like will take place within 200 feet of the shoreline. Moorage piling and moorage float installation will affect existing sub-tidal aquatic area, water depth Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 8 of 29

below minus 15 feet MLLW. Re-shaping of the existing rip-rap armored bank-line is proposed landward, up-slope of approximately plus 13 feet MLLW. 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. No dredging or fill activities are proposed. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No surface water withdrawals or diversions are proposed as part of the proposed project. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. The proposed fire station relocation project will alter existing sub-tidal and adjacent shoreline and upland areas. The proposed project includes activities that will take place in existing aquatic area, below MHHW. Please note, however, that the proposed project is located in non-flow restricted flood plain area in the north Elliott Bay. 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 proposed fire station relocation project does not include discharge of waste materials to aquatic area in north Elliott Bay. Two aspects of the proposed project are important to note regarding potential releases of contaminants to aquatic area in north Elliott Bay. First, all operating equipment at the site will be subject to best management practices (BMPs) and Spill Prevention, Containment and Countermeasures (SPCC) plans implemented to avoid and minimize potential releases of fuel and petroleum products used by construction equipment to the marine environment. Second, proposed construction activities will be controlled by best management practices intended to avoid and minimize potential releases of fugitive materials to the aquatic environment. Please refer to Section B.3.d. below for additional information concerning avoiding and minimizing potential adverse effects to aquatic area in north Elliott Bay, aquatic area important to fish and wildlife habitat. 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 proposed project, including piling, moorage float installation, placement of upland modular buildings, and re-shaping and planting of native riparian vegetation in approximately 425 linear feet of existing rip-rap armored bank-line does not include withdrawal of groundwater or discharge of materials to ground water at the project site. 2) Describe waste material 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. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 9 of 29

The proposed project does not include any discharge of waste material to ground water at the site. 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 into other waters? If so, describe. The proposed project includes installation of ten moorage guide piling and placement of five pre-fabricated moorage floats in existing sub-tidal aquatic area, water depth approximately minus 26 to 34 feet MLLW. Existing upland area at Pier 90 will receive three modular building structures. As a measure to off-set the potential adverse effect of new moorage float area, the project includes re-shaping of approximately 2125 square feet of existing armored, un-vegetated rip-rap bank-line, with the objective of establishing beneficial native riparian vegetation fish and wildlife habitat resource values in shoreline area adjacent to the project site. The proposed sub-tidal moorage area and armored bank- line retro-fit project elements do not include the potential for altering storm water conditions at the site. Installation of modular buildings in existing paved and drained upland area at Pier 90 will not include any new impervious surface or alter existing port- property storm water conveyance systems. Minor site excavation for the purpose of utility service is proposed. Trenching and pavement restoration will not result in changes to existing storm water collection or discharge conditions at the Pier 90 project site. Utility trench excavation and pavement restoration activities will be controlled using best management practices. These erosion control practices are expected to minimize and avoid potential discharges of sediment-laden storm water to the Pier 90 storm water system and to Elliott Bay. Operation of the relocated fire station facility will not alter the character of existing storm water discharge. 2) Could waste materials enter ground or surface waters? If so, generally describe. Only minimal volumes of waste materials, anticipated excess pavement ballast fill material or potentially contaminated previously place upland fill materials/soils, will be generated during utility trench excavation. All excavation materials will be confined and collected as they are exposed and identified, with the objective of avoiding and minimizing releases to surface water. Please note that motorized equipment used for construction activities at the project site will be subject to stringent controls prohibiting discharge of deleterious materials to the aquatic environment. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: All utility trench excavation and rip-rap armored shoreline re-shaping activities will be controlled to avoid and minimize potential releases of fugitive materials to surface water and ground water. Motorized equipment used to perform excavation and grading activities will be subject to prudent best management practices and stringent discharge controls. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 10 of 29

Potential adverse effects on water quality and wildlife are expected to be minor and limited to temporary, localized effects in the north end of the east slip at Terminal 91. Please note: (1) Utility trench work in existing upland area is limited to approximately 50 linear feet and a total of approximately 30 cubic yards. Existing pavement and under-lying select, compacted pavement section fill materials will be affected. (2) Re-shaping of existing rip-rap armored bank-line entails approximately 425 linear feet and 2125 square feet of bank-line work. Bank-line improvements for the purpose of creating native riparian vegetation resources, will be restricted to bank-line work between approximately plus 13 and 15 feet MLLW, above tidal influence. Approximately 110 cubic yards of soil/sand mixture will be installed in a planting terrace, created using existing rip-rap materials. Negative surface or water column effects will be avoided and minimized by the following construction controls and best management practices: • All armored bank-line work will be limited to periods determined by participating state and federal agencies to avoid potential adverse effects on migratory and resident fish and wildlife. • Best management practices, spill response procedures, and erosion and sediment control measures will be implemented during all phases of work in shoreline and upland locations to avoid discharges and prevent entry of deleterious materials to surface waters. No dredging or placement of fill material is proposed. 4. Plants a. Check or circle types of vegetation found on the site: ___ deciduous tree: alder, maple, aspen, other ___ evergreen tree: fir, cedar, pine, other ___ shrubs ___ grass ___ pasture ___ crop or grain ___ wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other ___ water plants: water lily, eelgrass, milfoil, other ___ other types of vegetation b. What kind and amount of vegetation will be removed or altered? The principal uses and activities at Terminal 91 include marine industrial cargo and passenger transfer use area. As a result, existing vegetation is limited to landscaped public use areas and entrance/access routes. Riparian vegetation is present at the existing 0.8 acre public shoreline access site (southwest Terminal 91) and upland landscape shrub and tree vegetation is in place in public pathway top-of-bank area adjacent to the Terminal 91 Galer Street vehicle entrance (central east portion of the site) and at the margin of an existing pedestrian/bicycle pathway northeast of the proposed project site. Inter-tidal and sub-tidal algal growth is present in many locations; however, no substantial growth of macro-algae is present at Terminal 91. No marsh vegetation is present at the site.

Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 11 of 29

Present upland and bank-line conditions at the proposed Terminal 91, Pier 90, fire station relocation site include paved upland pier area and rip-rap armored shoreline. No vegetation is present in these areas. Please note the present conditions at the rip-rap slope area proposed for re-shaping and installation of native riparian vegetation between approximately plus 13 and 15 feet MLLW include upland top-of-bank vegetation adjacent to a pedestrian/bicycle pathway. The present top-of-bank vegetation, elevation approximately plus 17.5 to 18.5 feet MLLW, consists of deciduous and evergreen trees (less than 15 feet in height), shrubs, and turf. No vegetation is present in the rip-rap armored area proposed for improvement with native riparian vegetation. The proposed shoreline rehabilitation project includes re-shaping the existing rip-rap armored bank- line to create approximately 425 linear feet (approximately 2125 square feet) of native riparian planting area, as a means of improving natural resource values in adjacent inter-tidal and shallow sub- tidal aquatic area. c. List threatened or endangered species known to be on or near the site. No threatened or endangered plant species are known to be in the project area. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: The objective of the proposed native riparian planting area is to re-shape existing rip-rap armored bank-line conditions, creating approximately 2125 square feet of planted terrace, between approximately plus 13 and 15 feet MLLW. The native riparian vegetation is intended to introduce terrestrial insects and organic detritus to the adjacent aquatic area, increasing natural resource values at the project site. No existing emergent vegetation or riparian vegetation will be affected or removed. 5. Animals a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: birds: hawk, heron, eagle, songbirds, other: mammals: deer, bear, elk, beaver, other: fish: bass, salmon, trout, herring, shellfish, other: The proposed fire station relocation site includes piling installation, placement of moorage floats, installation of upland modular structures, and establishing native riparian vegetation in an existing armored bank-line location. The proposed project site is located at the north end, terminus, of the east slip at Terminal 91, approximately 2500 feet north of open water in north Elliott Bay. Upland, shoreline, and aquatic area at the proposed project site have been significantly altered by past dredging and filling activities. Shore land and upland area at the site does not include significant upland habitat for birds or mammals. Aquatic area in adjacent north Elliott Bay provides habitat important to numerous species of resident and migratory fish and wildlife. The proposed project includes a modest amount of in-water structures, off-set with proposed armored shoreline rehabilitation as a native riparian planting area. Following re-shaping of the existing rip-rap bank-line, the bank-line terrace, between approximately plus 13 feet and 15 feet MLLW will receive dense plantings of native riparian trees and shrubs. This improvement is expected to enhance the aquatic resource value of existing adjacent intertidal and shallow sub-tidal area in the east slip, contributing terrestrial invertebrate prey items to the water surface and water column and exporting Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 12 of 29

organic litter and detritus to adjacent aquatic area. The objective of replacing barren rip-rap armor slope with native riparian trees and shrubs is to provide the potential for positive aquatic area effects, in order to offset potential negative effects due to installation of new in-water structures included in the proposed project. The proposed fire station moorage and rip-rap armored shoreline retro-fit represent minimal in-water construction activities. Proposed rip-rap bank-line re-shaping will not affect area subject to tidal influence. These activities will, however, require review by City of Seattle, state, and federal agencies. In recent years, development and construction activities in marine and estuarine locations in Puget Sound have been the subject of increased scrutiny as a result of Endangered Species Act listings, with particular concern for the life cycle and aquatic habitat requirements of ESA listed species. The following provides summary information concerning potential adverse effects on fish and wildlife due to the proposed fire station relocation project, emphasizing fish and wildlife of particular concern. Species listed under the Endangered Species Act (ESA) that may be present in the vicinity of the proposed fire station relocation project include: (1) Puget Sound Chinook salmon – threatened; (2) bull trout- threatened; (3) Stellar sea lion – threatened; (4) humpback whale – endangered; and (5) bald eagle – threatened. Elliott Bay, the East Waterway and West Waterway, and the Duwamish Waterway are part of a migration corridor important to anadromous salmon species. In particular, Puget Sound Chinook and bull trout are known to use the project area. Installation of moorage structures and re-shaping existing armored bank-line are not expected to result in direct effects, indirect effects, or cumulative effects on ESA-listed species of concern in the north Elliott Bay. Construction activities necessary for the fire station moorage and armored bank-line improvements have the potential to temporarily increase turbidity in water column habitat that could be occupied by sub-adult or adult salmonids, but no adverse effects are expected. Because specific project timing and construction methods will be used to control potential adverse effects, turbidity is not expected to affect juvenile Chinook salmon or bull trout. Bald eagles that may be present in the project area, and their prey, could be temporarily disturbed by shoreline construction activities. However, bald eagles that have been observed near the project area appear to be habituated to a relatively high level of human activity, and rehabilitation of shoreline at this location is not expected to adversely affect eagles. Further, given the large feeding territories occupied by bald eagles, temporary disturbance of prey at the relatively compact work site is not expected to impair foraging opportunities for these birds. The nearest known bald eagle nest sites are approximately 2.4 miles northwest and 3.4 miles south of the project site. Steller sea lions are not common in the project area and typically would not be expected to enter the area when construction activities occur. Humpback whales are unlikely to be present in the project area at any time. There are no direct, indirect, or cumulative effects due to the proposed project that are expected to adversely affected Steller sea lions or humpback whales. b. List any threatened or endangered species known to be on or near the site. Species listed under the Endangered Species Act (ESA) that may be present in the vicinity of the proposed shoreline restoration project include: (1) Puget Sound Chinook salmon – threatened; (2) bull trout- threatened; (3) Stellar sea lion – threatened; (4) humpback whale – endangered; and (5) bald eagle – threatened.

c. Is the site part of a migration route? If so, explain. Elliott Bay, the East and West Waterways, and the Duwamish Waterway, comprise a portion of the migration corridor important to anadromous salmon species, linking Elliott Bay and the Green/Duwamish watershed. In particular, Puget Sound Chinook and bull trout are known to use the project area. d. Proposed measures to preserve or enhance wildlife, if any: Measures to avoid and minimize potential adverse effects on ESA species of concern and, as a result, function as conservation measures, may include a combination of the following: • Timing restrictions specifying allowable in-water work periods. In-water activities necessary to relocate the Fire Station Number Five moorage, including installation of ten cylindrical steel guide piling in existing sub-tidal aquatic area in order to secure five 40 feet long, ten feet wide, concrete cell moorage floats would take place only between August 15 and February 15, or other period determined by state and federal agencies. Please note that the proposed project includes establishing approximately 2125 square feet of native riparian vegetation in an existing un-vegetated rip-rap bank-line, elevation approximately plus 13 feet to 15 feet MLLW. Bank-line riparian vegetation work is located up-slope of the MHHW contour and does not include in-water activities. As a prudent best management practice, however, bank- line vegetation work will take place during low water periods. • Water quality standards and procedures that limit the effect of turbidity to a defined mixing zone, stipulate limits for chemical constituents, dissolved oxygen, and other parameters, implemented by the Washington Department of Ecology. • Best management practices (BMPs ) required to reduce the potential for construction-related potential affects on aquatic species and their habitats, including: (1) prevention of releases of petroleum products, chemical, or other toxic or deleterious materials to the water; (2) immediate stop of work to report and contain any spills or releases, and, (3) preparation and application of a Spill Prevention, Control, and Countermeasure (SPCC) plan for use during all piling installation and bank-line re-shaping activities. The Pier 90, Terminal 91, fire station relocation project site includes existing filled upland, over-water piling supported pier area, and navigational access/vessel berth area. Upland, pier, and navigational access areas at Terminal 91 are built and committed to marine industrial cargo and passenger transfer uses and activities, with the principal site configuration in place for more than nine decades. Existing Terminal 91 facilities include bulk cargo transshipment areas, cruise vessel berths and passenger service structures, seafood receiving, processing and cold storage buildings, fishing vessel moorage, fishing and marine equipment fabrication and vessel outfitting, barge and tugboat moorage and service areas, and upland import/export vehicle and equipment staging areas. A total of approximately 825,000 square feet of cargo storage, food processing/cold storage, and fishing/marine equipment fabrication/repair buildings are present at Terminal 91. Terminal 91 includes two piers: Pier 90 at the east side of the terminal and Pier 91 on the west margin of the facility. Each pier consists of a filled center portion connecting to filled upland area at the north threshold of each pier. The west, south, and east perimeter of each pier includes concrete and treated wood piling supported dock area, approximately 80-85 feet wide, fitted with Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 14 of 29

combined timber/steel pier fender piling. Pier 90 is approximately 2350 feet long (north to south) and includes approximately 4125 linear feet of deep draft vessel moorage. Pier 91 is approximately 2500 feet long, with 4425 linear feet of deep draft vessel moorage. Existing aquatic area conditions adjacent to berth and navigational access facilities at Terminal 91 include the following general areas: (1) inter-tidal (plus 13 to minus eight feet MLLW); (2) shallow sub-tidal (minus eight feet to minus 15 feet MLLW); and, (3) sub-tidal (minus 15 to 35 feet MLLW) area. These aquatic area locations consist of sand/mud substrate in lower elevations and sand/rocky areas in inter-tidal locations. Aquatic area slopes at Terminal 91 are variable. Sub-tidal moorage areas, between minus 15 and 35 feet MLLW, include approximately 39 acres, with existing flat or very gradual slopes, characteristic of dredged and maintained navigational access conditions. Shallow sub-tidal area, minus 15 feet to minus eight feet MLLW, representing the transition between deep draft navigational access areas and more exposed upper tidal elevations, includes approximately 2.8 acres, with 1:1 to 3:1 substrate slopes. Existing exposed inter-tidal aquatic area at Terminal 91, extending up-slope from minus 8 feet to plus 13 feet MLLW, comprises approximately 13.2 acres, with substrate slopes between 3:1 and 8:1. Please note, an additional category of inter-tidal area at Terminal 91 includes structurally stabilized slope area beneath existing cargo piers. This inter-tidal slope area consists of riprap, slope 1.75:1 to 2:1, totaling approximately 17 acres. Re-shaping up to 425 linear feet of existing rip-rap armored bank-line to create approximately 2125 square feet of native riparian vegetation area, as a planting “terrace” located between approximately plus 13 feet and 15 feet MLLW, is proposed as a measure to off-set potential negative aquatic area effects due to placement of fire station moorage structures. The riparian planting terrace is proposed as a project element for enhancement of the biological resource value of adjacent intertidal and shallow sub-tidal aquatic areas. Please also see Section B.3.d. (Water) above for measures to avoid and minimize potential adverse effects on water resources important to the life forms noted above. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. No significant change in use of energy is anticipated to result from the proposed fire boat station relocation project, compared with existing energy use conditions at Terminal 91. Modular structures proposed for office, dormitory, and work area for fire station personnel will be “energy efficient”, including insulation and heating/air conditioning equipment. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. The proposed project will have no adverse effect on potential use of solar energy at adjacent sites. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: Fuel-efficient electrical and motorized equipment will be used to the extent possible during construction of the proposed project. Please note that the proposed project includes use modular Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 15 of 29

structures fabricated to meet current insulation and equipment energy use and conservation standards. 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. The proposed project does not include operations or activities with the potential to produce hazardous materials or waste products at the site. Please note that the proposed fire station relocation site, Pier 90, Terminal 91, includes more than nine decades of past marine industrial uses and activities, conducted by numerous public and private land-owners. The Terminal 91 site is subject to Resource Conservation and Recovery Act (RCRA) oversight. All clean-up and remediation activities at Terminal 91 are conducted in coordination and approval of the U.S. Environmental Protection Agency (EPA) and the Washington Department of Ecology (WDOE). Please note that the proposed fire station relocation project includes two limited activities with the potential to disturb areas which may include existing soil contamination. (1) Utility trenching: Approximately 50 linear feet of shallow utility trench excavation will be necessary to provide service to the proposed modular structures. Up to 30 cubic yards of excavation materials may be produced. The excavation materials will consist of select fill placed decades ago as foundation material for surface pavement. No native materials or deep fill materials will be excavated. Utility trench excavation is expected to entail removing an eight to ten inch existing asphalt pavement layer and under-lying select structural fill material. The fire station relocation site has no history of past industrial structures or marine industrial processing, with the area in continuous open space cargo marshalling and for the past six decades. All excavated material will be held in drainage controlled areas and re-used to the maximum extent possible as trench back-fill. Removed pavement and excess select fill materials will be disposed off-site at an approved receiving site, preceded by any necessary testing to verify the character of the excess/surplus materials. (2) Rip-rap armor bank-line re-shaping: Actions proposed for altering an existing riprap armored bank-line adjacent to the fire station moorage site include re-shaping, re-contouring the present bank-line sufficient to receive native riparian vegetation plantings. The present armored bank-line was constructed in 1985-1987. The bank-line area proposed for re-shaping has no record of past industrial or commercial use. Bank-line re-contouring will affect fractured armor stone and under-lying, clean select fill placed during construction in the period 1985-1987. It is unlikely that the bank-line improvements will encounter contaminated soils, however, shoreline work will be monitored for the presence of contamination. If contamination is suspected, subsequent testing will determine the necessity for placement of bank-line materials at an off-site controlled landfill or if bank-line materials may be safely re-used at the site in preparation of the riparian planting area. Please note that motorized equipment used for construction activities may include potentially hazardous materials in the form of fuel, lubricants, and associated materials. These materials will be subject to local, state, and federal controls and regulations pertaining to use, handling, and storage. No increase in exposure is anticipated. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 16 of 29

1) Describe special emergency services that might be required. No special emergency services are anticipated or necessary due to the proposed project. 2) Proposed measures to reduce or control environmental health hazards, if any: Potentially hazardous fuels, lubricants, and associated materials used for operation of motorized equipment as part of the proposed fire station relocation and riparian vegetation improvement project will be subject to existing local, state, and federal controls for use, handling, and storage, with the objective of avoiding potential environmental health exposure and hazards. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic equipment, operation, other)? The proposed fire station relocation and shoreline improvement work is located in the northeast portion of the existing Pier 90 area, Terminal 91. The site is in the Inter-Bay industrial area and existing sources of noise at the site include motor-driven vehicles, particularly heavy trucks and industrial equipment. Please note that residential areas are located within 0.45 and 0.8 miles, Queen Anne and Magnolia neighborhoods, respectively, of the project site. 2) What types and levels of noise would be created by or associated with the project on a short- term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Short-term noise levels will be affected at the site during construction. Noise-generating construction equipment will include installation of ten steel moorage guide piling, limited excavation and grading necessary for utility trenching, and hauling of project materials to and from the site. Please note that installation of steel moorage piling will be accomplished using vibratory pile driving equipment, as an alternative to impact pile driving. The moorage pilings are not required as structural piling and, as a result, load bearing requirements do not require deep penetration and use of impact pile driving techniques. Construction activities are expected to take place during normal working hours. It is expected that noise generated from construction equipment will be within existing industrial area day time baseline levels and noise levels are not expected to exceed industrial noise code standards implemented by City of Seattle. No significant increase in noise resulting from fire station use of the site is anticipated. Please note that fire boat and emergency response/rescue boats will not require or use sirens when entering or leaving the Pier 90, Terminal 91, moorage. 3) Proposed measures to reduce or control noise impacts, if any: All motorized construction equipment will be maintained and operated consistent with prudent measures to control potential noise emissions. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? The proposed fire station relocation project site is located at Terminal 91, at the south margin of the Inter-Bay industrial area, surrounded by sites and businesses built and committed to marine industrial use and general industrial uses and activities. b. Has the site been used for agriculture? If so, describe. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 17 of 29

The project site, as filled, former aquatic area in north Elliott Bay, has no historic agricultural use. c. Describe any structures on the site. The site proposed for relocation of Fire Station Number Five includes area at the northeast margin of Pier 90, Terminal 91. The area proposed for use by the fire station does not include existing, above-grade, upland structures. The fire station relocation site was selected, in part, to avoid the necessity of altering existing structures. The site has been used in past decades as open cargo marshalling area and has been intentionally managed as open cargo handling and equipment maneuvering area. Upland area elsewhere at the Terminal 91 site includes numerous improvements, please refer Item B.1.B. above. Similarly, pier and moorage areas at Terminal 91 include substantial improvements. The location of the proposed riparian planting action does not include structures of any kind. d. Will any structures be demolished? If so, what? The proposed project has been planned and designed to avoid the need for demolition of any sort. Removal of pavement, subsequent utility trench work, and re-shaping an existing armored rip-rap bank-line area include the only site work with the potential for disrupting existing marine cargo terminal and shoreline conditions. e. What is the current zoning classification of the site? The existing zoning classification is Heavy Industrial (IG1/U 65) f. What is the current comprehensive plan designation of the site? Existing comprehensive land use designations for the site include Heavy Industrial, General Industrial, and Manufacturing. g. If applicable, what is the current shoreline master program designation of the site? The present City of Seattle Shoreline Master Program designation for the site is Urban Industrial (UI). h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. City of Seattle Critical Area Maps indicate that the project site is within a liquefaction zone, since the upland and shoreline areas proposed for relocation of Fire Station Number Five and related establishment of riparian vegetation excavation and re-grading were created by means of fill placed in a portion of former north Elliott Bay tidelands. Liquefaction zones are considered environmentally sensitive but not environmentally critical areas. i. Approximately how many people would reside or work in the completed project? No residential uses are present at the project site and no residential occupancy is proposed. Workers employed at the finished fire station relocation site will be limited to Seattle Fire Department personnel, less than ten workers during typical conditions. j. Approximately how many people would the completed project displace? The completed project will not result in displacement of workers. k. Proposed measures to avoid or reduce displacement impacts, if any: No displacement of residents will result from the proposed project, therefore, no measures for avoiding or reducing displacement impacts are included in the present proposal. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 18 of 29

l. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The proposed fire station relocation project is consistent with existing plans approved by the City of Seattle and the port, relating to existing marine industrial use, public facilities, and improving shoreline habitat. Fire station relocation and establishment of native riparian vegetation at the proposed location are intended to be compatible with adjacent industrial uses and activities. The project is consistent with the port’s long-range Seaport facility objectives and consistent with the permitted uses and activities identified in the Seattle Shoreline Master Program. 9. Housing a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low-income housing. No housing units are included in the proposed project. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. No housing units would be eliminated due to the proposed project. c. Proposed measures to reduce or control housing impacts, if any: Since no housing resources will be affected, no measures to reduce or control adverse effects on housing are included in the present proposal. 10. Aesthetics a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? Proposed site changes include installation of three fire station structures, including two modular buildings and an arched, metal-framed storage tent. The tent structure is anticipated to be less than 35 feet above existing grade-level, with the modular buildings less than 20 feet above existing grade. The proposed moorage guide piling will extend approximately two to four feet above the level of the existing pier structure at northeast Pier 90. The riparian planting area will consist of native trees and shrubs, with the potential to extend 20 to 30 feet above existing top-of-bank elevations of approximately 17.5 to 18.5 feet above MLLW. b. What views in the immediate vicinity would be altered or obstructed? No adverse effects on views of adjacent water and shoreline areas are expected to result from the proposed fire station relocation and riparian planting project. Existing public use of aquatic area and shoreline locations adjacent to the project site will not be substantially altered. c. Proposed measures to reduce or control aesthetic impacts, if any: No significant changes in view conditions at the site are anticipated and no offsetting aesthetic measures are included in the present proposal. 11. Light and Glare a. What type of light or glare will the proposal produce? What time of day would it mainly occur? The proposed fire station relocation project does not include new lighting in existing upland area and will rely on the present Terminal 91 lighting system. The fire boat and emergency response boat moorage will include pedestal mounted lighting, consistent with worker safety requirements. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 19 of 29

b. Could light or glare from the finished project be a safety hazard or interfere with views? No lighting changes in upland locations are included in the present proposal. The proposed vessel moorage area will include pedestal-mounted safety lighting. The latter will be down-look lighting, directed to foot-traffic and areas required for movement of hand-carried fire department gear. No substantial changes in lighting are anticipated. Please note that moorage area lighting will be limited to foot traffic and moorage float surface areas, avoiding introduction of light in adjacent sub-tidal aquatic area. c. What existing off-site sources of light or glare may affect your proposal? No off-site sources of light and glare in the area of the project site are expected to adversely affect the present proposal. d. Proposed measures to reduce or control light and glare impacts, if any: No glare reduction or control measures are necessary. 12. Recreation a. What designated and informal recreational opportunities are in the immediate vicinity? The Port of Seattle has constructed and maintains three public shoreline access locations in the area of the proposed fire station relocation project: (1) Smith Cove Park: Located at the southwest margin of Terminal 91, west of Pier 91, with approximately 0.8 acres landscape upland area and approximately 520 linear feet of shoreline. (2) Terminal 91 Pedestrian/Bicycle Pathway: Including two landscaped corridors, with paved pathway. East-side—approximately 0.7 acres, 3800 feet in length, with landscape vegetation. West-side—approximately 1.4 acres, 3950 feet in length. (3) Centennial Park— approximately 10.5 acres and 4100 linear feet of shoreline, southeast of Terminal 91. Please note that a portion of the West-side pedestrian/bicycle pathway is located in existing upland area, adjacent and approximately 40 to 50 feet east of the armored bank-line site proposed for receiving native riparian vegetation planting as an element of the proposed fire station relocation project. b. Would the proposed project displace any existing recreational uses? If so, describe. The proposed project will not alter or disrupt existing public shoreline or recreational uses in the project area. c. Proposed measures to reduce or control impacts, if any: As described in Items A.11 and B.4.b, above, the objective of the riparian vegetation element of the proposed fire station relocation project is to off-set potential adverse effects due to new moorage float area in sub-tidal aquatic area at northeast Pier 90, Terminal 91. No negative effects on existing public shoreline use and open space areas are anticipated as a result of the proposed fire station relocation project. 13. Historic and Cultural Preservation a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe. No listed historic or cultural resource sites are known to be present at or adjacent to the project site. The possibility that historic or cultural resources are present at the site is low since the present shoreline site consists of fill placed in former aquatic area of north Elliott Bay. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 20 of 29

Please note that aquatic area in the vicinity of the project site consists of Treaty-reserved “usual and accustomed” fishing area. The Muckleshoot Indian Tribe, together with the Washington Department of Fish and Wildlife, manages fishing activity in this area. Fishing by Tribal members in this area is consistent with past federal government treaties and subsequent court decisions. Treaty fishing is an ongoing activity, and thus, a baseline condition within this area. Members of the Muckleshoot Indian Tribe harvest chinook, coho, chum, pink and steelhead salmon in the north Elliott Bay traditional fishing areas during summer, fall, and winter of each year, generally from August through February. The Pier 90, Terminal 91, project site can be considered an active Treaty fishing area. Please note, however, that the north end of the east slip at Terminal 91 has not been observed as a fishing location in the past 15 years. In light of existing navigational access uses and activities in the Terminal 91 east slip, the additional fire boat moorage use included in the present proposal is not expected to result in substantial change in the level of Treaty fishing access in the north end of the east slip at Terminal 91. b. Generally describe any landmarks or evidence of historic, archaeological, scientific, or cultural importance known to be on or next to the site. No landmarks or evidence of historic, archaeological, scientific, or cultural features of importance are known to be at the project site or potentially affected by project actions. c. Proposed measures to reduce or control impacts, if any: No potential adverse effects on historic resources are anticipated and no measures are proposed to reduce or control such effects. The port acknowledges the need to evaluate the present proposal in detail with the Muckleshoot Indian Tribe to determine potential actions which may be necessary to avoid and minimize potential negative effects on Treaty fishing access. It is important that construction activities necessary for the proposed project, and operation of the fire station moorage, avoid and minimize potential disruption of Treaty fishing activities. 14. Transportation a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on site plans, if any. The proposed fire station relocation project is located at the northeast margin of Pier 90, at Terminal 91, in the south BINMIC area of Seattle. The project site is west of Elliott Avenue West and south of the Garfield Street viaduct. The Terminal 91 project site is served by a vehicle entrance near West Galer Street, via a grade-separation overpass and vehicle ramp (also known as the Galer Street Overpass) connection to Elliott Avenue West. The Galer Street Overpass connects with the Seattle street grid via Elliott Avenue West, with direct links to all city arterial traffic routes. b. Is site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? Public transit routes are present at Elliott Avenue West, east of the project site, near the Elliott Avenue West and West Galer Street intersection. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 21 of 29

c. How many parking spaces would the completed project have? How many would the project eliminate? The proposed project includes on-site parking for fire department personnel. Relocation of Fire Station Number Five to Terminal 91 will not reduce the number of existing parking spaces designated for use at Terminal 91. The project site is located in an existing general cargo use area and placement of modular structures for use as a relocated fire station will include identification of new parking spaces adjacent to the structures. The newly identified spaces will not result in removal of existing parking spaces provided in adjacent locations or elsewhere at Terminal 91. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). The proposed project includes neither new roads or streets nor new street improvements. e. Will the project use (or occur in immediate vicinity of) water, rail, or air transportation? If so, generally describe. No changes in adjacent rail or air transportation will result from the proposed project. It is important to note that the proposed project is not expected to result in significant changes in vehicle use patterns or the number of vehicles requiring access at Terminal 91. f. How many vehicular trips per day would be generated by the completed project? If known, indicate when peak volumes would occur. No significant change in the volume vehicles serving Terminal 91 is expected. During construction, it is expected that vehicle use will include truck trips necessary for material hauling (including removal of materials and delivery of construction materials) and construction employee trips. The total number of construction vehicle trips is not expected to exceed 25 trips per day, during a potential 12 week construction period. g. Proposed measures to reduce or control transportation impacts, if any: No negative effects on transportation serving Terminal 91 or in the area of the project site are anticipated. Vehicle parking for up to ten fire station personnel and required for movement of fire station equipment will be accommodated at the project site. No measures to reduce or control potential negative effects on transportation are required. 15. Public Services a. Would the project result in an increased need for public services (for example: fire protection, police protection, health care, schools, other)? If so, generally describe. No increase in public services is anticipated as a result of the proposed project. b. Proposed measures to reduce or control direct impacts on public services, if any. No measures for offsetting, reducing or controlling negative effects on public services are required. Seattle Fire Department Temporary Fire Station Relocation SEPA No. 14-02 Page 22 of 29

16. Utilities a. Circle utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary sewer, septic system, other. The proposed project will require electrical, water, refuse, communication, and sanitary sewer service. Please note that Terminal 91 includes these services at present and no new utility service capacity is required at the project site. b. Describe the utilities that are proposed for the project, the utility providing the service and the general construction activities on the site or in the immediate vicinity that might be needed. Limited utility trenching and at-grade conduit placement will be required in order to connect/serve the proposed fire station modular structures via existing utility lines at Terminal 91. Please refer to Items A.11, B.1. g and B.1.h, and B.7.a for a description of utility service, activities necessary to connect utilities at the site, and evaluation of potential environmental effects of providing utility service.
