    Existing Site Conditions

    The proposed Cleveland High School Track and Field Improvements Project site is located in Seattle’s Beacon Hill Neighborhood (see Figure 1 and 2), adjacent to Cleveland High School. The approximately 2.8-acre (122,250 sq. ft.) site is comprised of two parcels. The northern parcel (Parcel No. 7549802085) is part of the overall property for Cleveland High School that is owned by Seattle Public Schools. This portion of the site is comprised of concrete tennis courts surrounded by chain-link fencing, a grass area that had been previously utilized for batting cages, a small storage building and the north portion (approximately 100 feet from north to south) of the existing field; a concrete retaining wall divides the tennis courts and former batting cage area from the existing field.

    The southern parcel (Parcel No. 7925100125) is owned by the City of Seattle Parks and Recreation Department and is comprised of the remainder of the existing grass field area. The existing athletic field is currently a flat natural grass playfield that was at one time surrounded by a natural dirt running track; currently the track is overgrown with vegetation.

    Due to the condition of the field, the use of the existing field by Cleveland High School is currently limited to practices and games for the school’s ultimate frisbee program[1]. All other athletic activities for Cleveland High School that require field use (soccer, football, baseball/softball, etc.) currently take place at other facilities in the surrounding area. Community uses of the field currently include football practices for the local little league football program (Beacon Hill Cowboys)[2], as well as informal community uses.

    There is currently no off-street parking available at the field; however, off-street parking is available within two parking lots at the adjacent Cleveland High School. On-street parking is also available adjacent to the western boundary of the site, along 13th Avenue South, as well as along other streets in the site vicinity.

    Proposed Project

    Project Design

    The proposed Cleveland High School Track and Field Improvements Project would replace the existing natural grass playfield and former tennis courts with a synthetic turf athletic field and other associated recreation facilities.

    Development of the north portion of the site would replace the existing tennis courts and grass area with batting cages and a synthetic turf warmup area. A pathway/stairway would provide a pedestrian connection with South Lucile Street to the north and the athletic field and track to the south.

    Development on the remainder of the site would replace the existing grass field with a new synthetic turf field that would provide space for football or soccer uses. A three lane rubberized track would surround the field. Facilities for other track and field uses would also be located surrounding the field, including, rubberized surfaces at the north end (for high jump) and the south end (for long jump, triple jump and pole vault); an area for shot put (rubberized pad and cinder landing area) would be provided beyond the track at the southeast corner of the site. A pole mounted, LED field lighting system would be provided surrounding the field area to allow for evening use of the field until approximately 11 PM, consistent with Seattle Parks and Recreation Department Policy #060-P7.1.1. The proposed lighting system would include four light poles surrounding the field and would incorporate 90-foot tall poles at each of the two western corners of the field and two 70-foot tall poles along the eastern side of the field.

    With the completion of the Cleveland High School Track and Field Improvements Project, several of Cleveland High School’s athletic activities that currently occur offsite would be able to utilize the new field area onsite due to the increased reliability of the field with synthetic turf surfaces and increased availability of the field due to the provision of field lighting. Existing off-site activities that would be able to use the new field, include soccer practices/games, football practices, junior varsity football games, ultimate frisbee practices/games, baseball/softball practices within the batting cages, and track and field; the Physical Education Department would also utilize the field at times for portions of its classes. Little league football (Beacon Hill Cowboys) practices/games would continue to occur on the fields during the Fall. Other community uses would include Seattle Parks and Recreation programs such as adult and youth soccer games, ultimate frisbee games, and use of the track. Use of the field between Cleveland High School and the Seattle Parks and Recreation Department would continue to follow the existing Joint Use Agreement[3] between the two entities.

    Off-street parking would be provided within the existing parking lots at Cleveland High School (approximately 127 total parking stalls). On-street parking would also continue to be available along 13th Avenue South adjacent to the field, as well as other streets within the site vicinity.

    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. If a proposal would occur over a range of area, provide the range or boundaries of the site(s).

    The project site is located in the Beacon Hill neighborhood of Seattle, immediately to the west of Cleveland High School. The project site is bounded by South Lucile Street to the north; Cleveland High School to the east; Interstate 5 (I-5) to the south; and 13th Avenue South to the west (see Figure 2 for further details). As described above, the site is comprised of two parcels. The northern parcel (Parcel No. 7549802085) is part of the overall property for Cleveland High School that is owned by Seattle Public Schools and is addressed as 5511 15th Avenue South. The southern parcel (Parcel No. 7925100125) is owned by the City of Seattle Parks and Recreation Department and is addressed as 5512 and 5524 13th Avenue South.

    B. Environmental Elements

    1. Earth

    a. General description of the site (circle one):

    Flat, rolling, hilly, steep slopes, mountainous, other:_______________________________________

    The Cleveland High School Track and Field Improvements Project site is generally flat. The grade of the site generally follows a northeast to southwest direction with the highest point at an elevation of approximately 96 feet (above sea level) in the northeast portion of the site and the lowest point at an elevation of approximately 80 feet (above sea level) in the southwest portion (see Figure 4 for a survey of the site). According to City of Seattle Environmentally Critical Areas Maps, a Steep Slope Environmentally Critical Area (ECA) is located off-site, to the east of the site.

    b. What is the steepest slope on the site (approximate percent slope)?

    There are no steep slopes on the project site. The Steep Slope Area to the east of the project site has a grade of approximately 55% from east to west.

    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 agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils.

    As noted in the Geotechnical Report for the project (Shannon and Wilson, Inc., April 2017), soils on the project site generally consist of a thin layer of grass and sod with a layer of fill underneath. The fill layer consists of loose to medium dense silty sand with gravel to sandy, lean clay, and ranges from a depth of 2 ft. to 14 ft. In some areas, weathered siltstone and glacial till underlies the fill material. See Appendix A for further details.

    The project site does not contain agricultural land areas of commercial significance.

    d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe.

    In general the Puget Sound region is a seismically active region; thus the project site could experience seismic activity, which may cause surface rupture, liquefaction and subsidence, and landslides. However, based on site conditions, the risk of these hazards is considered low.

    During geotechnical investigations on the site, a former shallow landslide area (approximately 15 feet wide) was observed in the steep slope area to the east of the project site which caused a concrete pathway and railing to fail within that area. Based on subsurface conditions underlying the slope and the lack of visual evidence of that the slope is experiencing vertical instability it is anticipated that the slope area is currently in stable condition (Shannon and Wilson, Inc., June 2017).

    e. Describe the purpose, type, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill.

    It is anticipated that approximately 1,810 cubic yards of material would be excavated from the site for this project. Approximately 4,000 cubic yards of engineered aggregate and other bulk materials (e.g. aggregates, asphalt and concrete) would also be imported to the site during construction. The total affected area for the new field surfaces and associated areas would be approximately 122,250 sq. ft.

    f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.

    Erosion is possible in conjunction with any construction activity. Site work would expose soils, but the implementation of a Temporary Erosion Sedimentation Control (TESC) plan would mitigate potential impacts. Once the field area is operational, no erosion is anticipated.

    g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)?

    A complete Drainage and Stormwater Technical Information Report is currently being developed as the Cleveland High School Track and Field Improvements Project moves toward compliance with the applicable codes. Because the majority of the site is a pervious athletic field that is underdrained, and because exactly how the existing and proposed surfaces are interpreted as “impervious surfaces” or not dramatically alters the percentage impervious surface calculation, this question cannot be answered definitively. Ultimately, the proposed project will comply with Seattle Municipal Code requirements.

    h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:

    The following measures would be provided to reduce/control erosion impacts during construction:

    • Comprehensive Drainage Control Plan approvals (including Construction Best Management Practices, Erosion and Sediment Control approvals) would be submitted as an element of the permit review process.
    • A Construction Stormwater Pollution Prevention Plan (SWPPP) would be prepared for the proposed project.

    2. Air

    a. What type 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.

    During construction, the Cleveland High School Track and Field Improvements Project could result in temporary increases in localized air emissions associated with particulates and construction-related vehicles. It is anticipated that the primary source of temporary, localized increases in air quality emissions would result from particulates associated with on-site demolition, excavation, and site preparation. While the potential for increased, air quality emissions could occur throughout the construction process, the timeframe of greatest potential impact would be at the outset of the project in conjunction with the site preparation and excavation/grading activities.

    Temporary, localized emissions (including GHG emissions associated with carbon monoxide and hydrocarbons) would result from diesel and gasoline-powered construction equipment operating onsite, construction traffic accessing the site, and construction worker traffic. The construction effort would include earthwork activities consisting of approximately 1,810 cubic yards of cut and exported material and the import of approximately 4,000 cubic yards of aggregates and other bulk materials. The more intensive portion of the effort would be the import and delivery of materials which is estimated to require approximately 175 truck trips. The highest volume of truck traffic would likely occur in July and August, but would not be anticipated to result in significant air quality impacts. Installation of the rubberized track surface would also include a final texture coating that could result in temporary odors that would be noticeable in the immediate vicinity of the site.

    Upon completion of the project, the primary source of emissions would be from vehicles travelling to and from the site. Emissions from such vehicles would not be anticipated to result in a significant adverse air quality impact.

    b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe.

    There are no offsite sources of air emissions or odors that may affect the proposed project.

    c. Proposed measures to reduce or control emissions or other impacts to air, if any:

    The following measure would be provided to reduce/control air quality impacts during construction:

    • Construction activities would be required to comply with Puget Sound Clean Air Agency (PSCAA) regulations, including Regulation I, Section 9.11 (prohibiting the emission of air contaminants that would be injurious to human health) and Regulation I, Section 9.15 (prohibiting the emission of fugitive dust, unless reasonable precautions are employed). Additional mitigation measures to minimize air quality impacts during construction are identified in Appendix A.

    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.

    There is no surface water body in the immediate vicinity of the site. The closest surface water body is the Duwamish River, which is located approximately 1-mile to the west of the site (see Figure 1).

    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 not require any work over, in, or adjacent any surface water body.

    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 fill or dredge material would be placed in or removed from any surface water body as a result of the proposed project.

    4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known.

    The proposed project would not require any surface water withdrawals or diversions.

    5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan.

    The project site does not lie within a 100-year floodplain and is not identified as a flood prone area on the City of Seattle Environmentally Critical Areas map.

    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.

    There would be no discharge of waste materials to surface waters with the proposed project. All waste materials generated during construction (i.e., grading spoils and demolition debris) would be transported offsite to an appropriate disposal facility.

    b. Ground water:

    1) Will ground water be withdrawn, or will water be discharged to ground water? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known.

    During geotechnical investigations on the site (Shannon and Wilson, Inc., April 2017), seven borings were conducted ranging from a depth of approximately 6.5 feet below the ground surface to approximately 19 feet below the ground surface. The groundwater table was not encountered during any of these borings. No groundwater would be withdrawn or water discharged to ground water as part of the project (see Appendix A for details).

    2) Describe waste material that will be discharged into the ground from septic tanks or other sources; 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.

    Waste material would not be discharged into the ground from septic tanks or other sources.

    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.

    During construction, a temporary stormwater management system would be provided in compliance with City of Seattle and Washington State Department of Ecology standards and requirements.

    The primary source of stormwater runoff from the Cleveland High School Track and Field Improvements Project would be rainfall. Rainfall landing upon the field and track surface would percolate vertically through the engineered permeable aggregate base profile. Stormwater would be collected in a subsurface drainage system and routed via underground piping through an engineered flow control device. The discharge from the flow control device would connect to the existing combined sewer system. The combined sewer system discharges to an existing sewer treatment facility.

    2) Could waste materials enter ground or surface waters? If so, generally describe.

    The proposed stormwater management system and associated mitigation measures would prevent waste materials from entering the ground water or surface waters. Erosion and sedimentation control measures would be implemented per City of Seattle requirements. The proposed project would not involve any waste materials that could enter ground or surface waters.

    3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe.

    The proposed project would not alter or otherwise affect drainage patterns in the site vicinity. The slope of the proposed field would remain similar to existing conditions and the underdrain system would continue to convey runoff to the south.

    d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any:

    The following measures would be implemented to control surface, ground and runoff water impacts:

    • The project would comply with applicable requirements relating to surface water runoff control and water quality, including the City of Seattle’s Drainage Control Ordinance and 2016 City of Seattle Stormwater Manual.
    • The project would require City of Seattle approval of a Comprehensive Drainage Control Plan (including Construction Best Management Practices, Erosion and Sediment Control approvals) as part of the permit process.
    • To ensure that peak flow rates from the effective impervious surfaces would be less than the allowed rates as established by the City of Seattle, flow control would be added to the stormwater discharge point from the field area. The flow control would utilize a permeable aggregate basin located at the downstream end of the field. Limited storage would be available across the standard permeable base section through the rest of the field and the network of underdrain piping. With the flow control structure in place, for most rain events there would be a reduction in runoff rates from the project area.

    4. Plants

    a. Check or circle types of vegetation found on the site:

    X_deciduous tree:
    X_evergreen tree:
    X_shrubs
    X_grass
    __ pasture
    __ crop or grain
    __ wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other
    __ water plants: water lily, eelgrass, milfoil, other
    __ other types of vegetation

    Existing trees and shrubs are located in the northern, southern and eastern portions of the Cleveland High School Track and Field Improvements Project site, primarily near the edges of the project boundary. The existing field area is comprised of grass and weeds.

    b. What kind and amount of vegetation will be removed or altered?

    No trees are proposed to be removed as part of the project. Existing grass, weeds and shrubs within the proposed field area would be removed as part of the project. The proposed field area would be comprised of synthetic turf with a rubberized surface track and associated facilities surrounding the field.

    c. List threatened or endangered species known to be on or near the site.

    No known threatened or endangered species are located on or proximate to the project site.

    d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any:

    No trees are proposed to be removed as part of the project. The existing trees that are currently located along the northern, southern and eastern edges of the site would be retained and protected during construction.

    e. List all noxious weeds and invasive species known to be on or near the site.

    Noxious weeds and invasive species that are present on the site and in the vicinity of the site include Himalayan blackberry and English ivy.

    Back to Top

    5. Animals

    a. Circle (underlined) any birds and animals that have been observed on or near the site or are known to be on or near the site:

    birds: songbirds, hawk, heron, eagle,other: crows, pigeons

    mammals: deer, bear, elk, beaver, other: squirrels

    fish: bass, salmon, trout, herring, shellfish, other: None.

    b. List any threatened or endangered species known to be on or near the site.

    The following are listed threatened or endangered species that could be present within the Cleveland High School Track and Field Improvements Project site area or surrounding vicinity based on data from the U.S. Fish and Wildlife Service: marbled murrelet, streaked horned lark, yellow-billed cuckoo, bull trout, and north american wolverine[4]. However, it should be noted that none of these species have been observed at the site and due to the urban location of the site, it is unlikely that these animals are present on the site

    c. Is the site part of a migration route? If so, explain.

    The entire Puget Sound area is within the Pacific Flyway, which is a major north-south flyway for migratory birds in America, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites.

    d. Proposed measures to preserve or enhance wildlife, if any:

    No specific measures are required/proposed to enhance wildlife and/or habitat.

    e. List any invasive animal species known to be on or near the site.

    Invasive species known to be located in King County include European starling, house sparrow and eastern gray squirrel.

    Back to Top

    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.

    Electricity is the primary source of energy that would serve the proposed Cleveland High School Track and Field Improvements Project. During operation, this energy source would be used for field lighting. The field lights would generally operate until approximately 11 PM, consistent with Seattle Parks and Recreation Department Policy #060-P7.1.1.

    b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe.

    The proposed project would not affect adjacent properties use of solar energy.

    d. 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:

    The following measures would be provided to conserve energy and minimize energy impacts.

    • The proposed field lighting for the project would utilize LED lighting fixtures which would be more efficient and conserve energy when compared with traditional metal halide light fixtures.
    • The proposed field lighting system would be connected to a fully programmable control system with remote operation to allow field lights to be turned off after play is completed and area lights would remain on for a short period of time to allow ample light for safe egress from the site.

    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 completed Cleveland High School Track and Field Improvements Project would have no known environmental health hazards that could occur as a result of this proposal.

    1) Describe any known or possible contamination at the site from present or past uses.

    No known sources of potential contamination are present on the site.

    2) Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity.

    No existing hazardous chemicals/conditions are located within the project area.

    3) Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project’s development or construction, or at any time during the operating life of the project.

    No toxic or hazardous chemicals are anticipated to be stored, used or produced during the project’s development or operation. Installation of the rubberized track surface would include a final texture coating that could result in temporary odors that would be noticeable in the immediate vicinity of the site, but such materials are not anticipated to be hazardous to human health.

    4) Describe special emergency services that might be required.

    No special emergency services are anticipated to be required as a result of the project. As is typical of urban development, it is possible that normal fire, medical, and other emergency services may, on occasion, be needed from the City of Seattle.

    5) Proposed measures to reduce or control environmental health hazards, if any:

    No known environmental health hazards are anticipated as part of the project and no mitigation would be required.

    b. Noise

    1) What types of noise exist in the area that may affect your project (for example: traffic, equipment operation, other)?

    Traffic noise associated with adjacent roadways is relatively high due to the site’s proximity to the I-5 freeway (located adjacent to the southern boundary of the site). In addition, noise associated with overflights of airplanes taking off or landing at Boeing Field (approximately 0.5-mile to the south of the project site) is noticeable at the project site. Neither the traffic noise nor the overflights, are expected to adversely affect the proposed Cleveland High School Track and Field Improvements Project.

    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 site.

    Short-Term Noise

    Temporary construction-related noise would occur as a result of on-site construction activities associated with the project. Residential land uses (particularly those to the immediate west of the site, beyond 13th Avenue S) would be the most sensitive noise receptors and could experience occasional noise-related impacts throughout the construction process. The proposed project would comply with provisions of Seattle’s Noise Code (SMC, Chapter 25.08) as it relates to construction-related noise to reduce noise impacts during construction.

    Long-Term Noise

    Upon completion of construction, the proposed Cleveland High School Track and Field Improvements Project would result in increased noise on the project site associated with increased use of the field and associated facilities. As described previously, use of the fields would include Cleveland High School athletic activities, such as soccer practices/games, football practices, junior varsity football games, ultimate frisbee practices/games, baseball/softball practices within the batting cages, track and field and use by the Physical Education Department for portions of its classes. Community uses would include little league football (Beacon Hill Cowboys) practices/games and Seattle Parks and Recreation programs such as adult and youth soccer games, ultimate frisbee games, and use of the track.

    Increased noise on the site would primarily be associated with noise from athletic participants during practices and games and crowd noise during games. Typical noise levels from sporting events were analyzed as part of the City of Seattle’s 2002 EIS for the Sand Point Magnuson Park Drainage, Wetland/Habitat Complex and Sports Fields/Courts Project (2002 Sand Point Magnuson Park EIS), which included similar athletic activities as the proposed Cleveland High School Track and Field Improvements Project. The 2002 Sand Point Magnuson Park EIS indicated that youth soccer practices/games and adult league soccer games would all generate the following noise levels:

    • L25[5]: 52 dB(A) at 30 meters
    • Lmax[6]: 68 dB(A) at 30 meters

    It would be anticipated that youth soccer practices/games and adult soccer games (and other athletic activities, practices and games) at the Cleveland High School Track and Field Improvements Project site would generate a similar level of noise as identified above in the 2002 Sand Point Magnuson Park EIS.

    These sound levels associated with field uses (L25 of 52 dB(A) and Lmax of 68 dB(A)) would be within the exterior sound level limits identified in SMC 25.08.410, which includes average sound level limits of 55 dB(A) for residential receiving properties and maximum sound level limits (Lmax) of no more than 15 dB(A) above the exterior sound level limit (e.g. 70 dB(A)) for residential receiving properties). However, the site and surrounding area also contain a high level of existing noise due to the proximity to vehicle traffic noise from I-5 and noise from airplane overflights to and from Boeing Field. As result, it is anticipated that the Cleveland High School Track and Field Improvements Project are not be anticipated to result in significant noise impacts.

    3) Proposed measures to reduce or control noise impacts, if any:

    The following measures would be provided to reduce noise impacts:

    • As noted, the project would comply with provisions of the City’s Noise Ordinance (SMC 25.08); specifically: construction hours would be limited to standard construction hours (non-holiday) from 7 AM to 7 PM and Saturdays and Sundays from 9 AM to 7 PM.If extended construction hours are necessary, the applicant would apply for a noise variance.
    • The use of the field would comply with City of Seattle Parks and Recreation Department Policy #060-P7.1.1, which allows for field use until 11 PM.

    8. Land and Shoreline Use

    a. What is the current use of the site and adjacent properties? Will the proposal affect current land uses on nearby or adjacent properties? If so, describe.

    The Cleveland High School Track and Field Improvements Project site is currently used for a limited number of activities, including Cleveland High School’s Ultimate Frisbee practice, school outdoor events (Eagle Day), and the Beacon Hill Cowboy’s little league football practice. All other school-related athletic activities occur elsewhere due to field safety issues and schedule conflicts.

    Adjacent land uses to the project site include:

    • North – South Lucile Street and one- to two-story single family residences;
    • East – Cleveland High School, separated from the field by existing vegetation/trees and a steep slope area;
    • South – I-5, which separates the site from an industrial area and the Boeing Field/King County International Airport; and,
    • West – 13th Avenue South, one- to two-story single family residences and two- to three-story multifamily residences.

    b. Has the site been used as working farmlands or working forest lands? If so, describe. How much agricultural or forest land of long-term commercial significance will be converted to other uses as a result of the proposal, if any? If resource lands have not been designated, how many acres in farmland or forest land tax status will be converted to nonfarm or nonforest use?

    The site has no recent history of use as a working farmland or forest land.

    1) Will the proposal affect or be affected by surrounding working farm or forest land normal business operations, such as oversize equipment access, the application of pesticides, tilling, and harvesting? If so, how:

    The site is located in an urban area and would not affect or be affected by working farm or forest land; no working farm or forest land is located in the vicinity of this urban site.

    c. Describe any structures on the site.

    A small, concrete block storage building is located in the northwest portion of the site. Other structures that are located on the site include an existing retaining wall and the concrete tennis courts on the north end of the site.

    d. Will any structures be demolished? If so, what?

    The existing structures would remain on the site as part of the project. The existing storage building and retaining wall would remain in their current locations. The existing tennis courts would also remain in place but would be covered by a drainage mat and synthetic turf as part of the proposed batting cage use within that area. Portions of the existing tennis court surface and retaining wall may be selectively removed to allow for the development of the pathway/stairway connection from South Lucile Street.

    e. What is the current zoning classification of the site?

    The site is currently zoned Low Rise 2 (LR2).

    f. What is the current comprehensive plan designation of the site?

    The Future Land Use Map in the Seattle Comprehensive Plan identifies the site as City-Owned Open Space. The surrounding area is designated Multi-Family Residential Area.

    g. If applicable, what is the current shoreline master program designation of the site?

    The project site is not located within the City’s designated shoreline boundary.

    h. Has any part of the site been classified as a critical area by the city or county? If so, specify.

    A Steep Slope Environmentally Critical Area (ECA) is mapped on the eastern edge of the site, but is located outside of the project area. As noted under the Earth discussion, the Steep Slope Area to the east of the project site has a grade of approximately 55% from east to west. Based on subsurface conditions underlying the slope and the lack of visual evidence that the slope is experiencing vertical instability it is anticipated that the slope area is currently in stable condition (Shannon and Wilson, Inc., June 2017). See Appendix A for further details.

    i. Approximately how many people would reside or work in the completed project?

    No people would work or reside in the completed project.

    j. Approximately how many people would the completed project displace?

    The completed project would not displace any existing residents or employees.

    k. Proposed measures to avoid or reduce displacement impacts, if any:

    No displacement impacts would occur and no mitigation measures are necessary.

    l. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any:

    The project site is designated on the City of Seattle Comprehensive Plan Future Land Use Map as City-Owned Open Space. The proposed Cleveland High School Track and Field Improvements Project would be consistent with the future land use designation for the site by maintaining the recreational/open space use of the site. The new field improvements on the site would provide enhanced recreational opportunities for the adjacent Cleveland High School, the Seattle Parks and Recreation Department and the surrounding community. Pursuant with City of Seattle regulations, a conditional use permit would also be required from the City of Seattle to allow for the increased height necessary to allow for the 70- to 90-foot tall light poles.

    m. Proposed measures to ensure the proposal is compatible with nearby agricultural and forest lands of long-term commercial significance, if any:

    The project site is not located near agricultural or forest lands and no mitigation measures are necessary.

    Back to Top

    9. Housing

    a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low-income housing.

    No housing units would be provided.

    b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing.

    No housing presently exists onsite and none would be eliminated.

    c. Proposed measures to reduce or control housing impacts, if any:

    No housing impacts would occur and no mitigation would be necessary.

    Back to Top

    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?

    The proposed field lighting poles are anticipated to be approximately 70- to 90-feet high (see the Light and Glare discussion below for further details on the proposed field lighting poles).

    b. What views in the immediate vicinity would be altered or obstructed?

    Views of the existing grass field and tennis courts on the site would be replaced with a new synthetic turf field, three-lane track and associated facilities. Four field lighting poles that would be approximately 70- to 90-foot tall would be provided surrounding the field area. Views toward the project site would be altered from the existing grass field and tennis courts to reflect the new field improvements. From nearby locations, existing background views (i.e., views of buildings beyond the site) are not anticipated to be obstructed by the proposed Cleveland High School Track and Field Improvements Project.

    The City’s public view protection policies are intended to “protect public views of significant natural and human-made features: Mount Rainier, the Olympic and Cascade Mountains, the downtown skyline, and major bodies of water including Puget Sound, Lake Washington, Lake Union and the Ship Canal, from public places consisting of specified viewpoints, parks, scenic routes, and view corridors identified in Attachment 1” to the SEPA code[7]. The project site is identified as an officially-designated SEPA public viewpoint (Cleveland High School Playfield) due to the views available to the south and southeast of Mount Rainier and the façade of the existing Cleveland High School (a designated City of Seattle Landmark). Development of the proposed Cleveland High School Track and Field Improvements Project would not be anticipated to obstruct views of Mount Rainier or the façade of Cleveland High School; however, depending on the location of the individual viewer, one or more of the proposed light poles could be located within the field of view toward Mount Rainier or Cleveland High School.

    View protection from City-designated Scenic Routes is also encouraged[8]. In the vicinity of the project site, there is one designated Scenic Route: I-5. The Cleveland High School Track and Field Improvements Project is located to the north and east of I-5. Due to the existing topography, existing trees and the presence of existing concrete barrier walls, the project site is not generally visible from vehicles travelling northbound on I-5 in the vicinity of the site. The project site is also not generally visible from southbound I-5; however, the existing Cleveland High School is visible for drivers travelling southbound on I-5. Proposed field lighting poles surrounding the field area could be visible to drivers from certain portions of southbound I-5, but are not be anticipated to obstruct existing views toward Cleveland High School.

    The adjacent Cleveland High School building is designated by the City of Seattle as a City Landmark and views of designated historic structures is also a consideration[9]. The proposed Cleveland High School Track and Field Improvements Project would not result in any modifications to the existing Cleveland High School building and views of the building from the north, east and south of the building would remain generally unchanged. Views of Cleveland High School from the west could include a portion of the field lighting poles that are included as part of the proposed project; however, these lighting poles would not obstruct views of the existing building and are not anticipated to significantly impact views of Cleveland High School.

    There are no designated views of the Space Needle on or adjacent to the project site[10].

    c. Proposed measures to reduce or control aesthetic impacts, if any:

    No significant impacts are anticipated with regard to aesthetic conditions or views associated with the proposed project and no measures are proposed.

    Back to Top

    11. Light and Glare

    a. What type of light or glare will the proposal produce? What time of day would it mainly occur?

    Short-Term Light and Glare

    At times during the construction process, temporary area lighting of the job site (to meet safety requirements) may be necessary, which will be noticeable proximate to the project site. In general, however, light and glare from construction of the proposed project are not anticipated to adversely affect adjacent land uses.

    Long-Term Light and Glare

    The proposed Cleveland High School Track and Field Improvements Project would introduce new sources of light and glare on the project site, including pole-mounted field lighting and additional mobile sources of light associated with vehicles travelling to and from the site. The use of the track and field and associated lighting would comply with City of Seattle Parks and Recreation Department Policy #060-P7.1.1, which allows for field use until 11 PM.

    The project would include four pole-mounted lighting fixtures surrounding the field (see below for an example of the type of shielded light fixtures that would be utilized as part of the project). Due to the existing site dimensions, the proximity of the adjacent right-of-way and setback requirements, the light poles along the west side of the field would be located inside of the track, while the light poles on the east side would be located outside of the track. The proposed lighting systems features shielded high efficiency LED arrays that allow for more precise control of light to be delivered to the field area and minimize the amount of light that can be transmitted offsite and into the atmosphere (Stantec, 2017).

    The design of the lighting system would minimize the amount of light spillage from the site. By utilizing a pole height of 70- to 90-feet (compared to 30 feet), the amount of light spillage would be reduced by allowing the lights to be aimed down toward the field and away from adjacent properties. The height also allows for increased effectiveness of the internal/external shielding on the lights to control the emitted light and prevent light from escaping beyond the site. In addition, “sky glow” would also be minimized through the use of 70- to 90-foot tall poles, internal/external shielding, and the use of “full cutoff” style LED lights that provide advanced light control and shielding to limit light that is emitted to the atmosphere (Stantec, 2017).

    The primary sources of glare from the proposed project would be direct glare from the lights, as well as reflected glare off of the light poles, lights and surfaces around the field. Mounting the lights on 70- to 90-foot tall poles would reduce the amount of glare by creating steeper aiming angles and more effective use of the light shields. Residences that are immediately west of the field would have the have the potential for low to moderate levels of direct glare due to their proximity to the site. These residences would also have the greatest potential for exposure to reflected glare from field surfaces, pavement, etc. Residences to the north would experience minimal direct glare due to their higher elevation from the site (Stantec, 2017). See Appendix C for further details on light and glare.

    b. Could light or glare from the finished project be a safety hazard or interfere with views?

    Light and glare associated with the proposed project would increase as part of the project when compared to the existing conditions, but the proposed lighting design is intended to minimize impacts from the field lighting system and associated glare. As a result, light and glare are not be expected to cause a safety hazard nor interfere with views.

    c. What existing off-site sources of light or glare may affect your proposal?

    No off-site sources of light or glare are anticipated to affect the proposed Cleveland High School Track and Field Improvements Project.

    d. Proposed measures to reduce or control light and glare impacts, if any:

    The following measures would be implemented to minimize light and glare impacts from the proposed project:

    • Light fixtures would be mounted on 70- to 90-foot tall poles to minimize light spillage and glare by allowing the fixtures to be aimed more directly down to the field and away from offsite areas. The height of the poles would also allow for greater effectiveness of internal/external shielding on the lights.
    • Light fixtures would utilize a reflector and shielding design to reduce the amount of light emitted from the site and into the atmosphere. An additional external visor would be mounted onto the light that extends to the front of the light to further limit the amount of light that is emitted above the system.

    12. Recreation

    a. What designated and informal recreational opportunities are in the immediate vicinity?

    As described above, the Cleveland High School Track and Field Improvements Project site is currently used for a limited number of activities, including Cleveland High School’s Ultimate Frisbee practice, school outdoor events (Eagle Day), and the Beacon Hill Cowboy’s little league football practice, as well as general community use.

    There are several additional parks in the general vicinity of the project site, including:

    • Maple Wood Playfield is located approximately 0.5 miles north of the project site;
    • Ruby Chow Park is located approximately 0.3 miles south of the project site; and,
    • Maple School Ravine is located approximately 0.3 miles east of the project site.

    b. Would the proposed project displace any existing recreational uses? If so, describe.

    The proposed project would result in the repurposing of the existing tennis court and the grass field that is currently used for limited recreational activities.

    c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any:

    The proposed Cleveland High School Track and Field Improvements Project would provide enhanced recreation opportunities for Cleveland High School, the Seattle Parks and Recreation Department, and the surrounding community with a new, synthetic turf field, 3-lane rubberized track and associated track and field facilities, and batting cage areas. No additional mitigation for recreation impacts is necessary.

    Back to Top

    13. Historic and Cultural Preservation

    a. Are there any buildings, structures, or sites, located on or near the site that are over 45 years old listed in or eligible for listing in national, state, or local preservation registers located on or near the site? If so, specifically describe.

    There is one City of Seattle Landmark immediately adjacent the site: Cleveland High School, located at 5511 15th Avenue S. The school was established in 1927 and became a City Landmark in 2003. The three-story brick building sits atop southwestern Beacon Hill and overlooks the project site, as well as Georgetown, the Duwamish River valley, Boeing Field, and I-5. No modifications to the existing Cleveland High School building are included as part of the proposed Cleveland High School Track and Field Improvements Project.

    Other City Landmarks in the vicinity of the project site include Georgetown Steam Plant (less than 0.25 miles southwest); Rainier Cold Storage/Ice/Seattle Brewing/Malting Co. Building (approximately 0.25 miles south); and Old Georgetown City Hall (approximately 0.5 miles south).

    There are no buildings, structures, or sites registered on any state or national preservation registers in the vicinity of the project site. However, there are numerous buildings that meet the age threshold for registration situated three or more blocks from the project site. Of these, the closest is St. George Catholic Church, located at 13th Avenue South, built in 1903. The church, as well as the other structures over 45 years old in the general vicinity of the project site, are not listed on a historic register.

    b. Are there any landmarks, features, or other evidence of Indian or historic use or occupation? This may include human burials or old cemeteries. Are there any material evidence, artifacts, or areas of cultural importance on or near the site? Please list any professional studies conducted at the site to identify such resources.

    As noted above, the Cleveland High School building was designated as a City of Seattle Landmark in 2003; however, the proposed project does not include any modifications to the existing building.

    A cultural resources assessment was completed for the project and included an analysis of the natural and cultural setting of the site, background research on the site and surrounding area (archival research about the natural history and human settlement of the area, identification of previous cultural resource assessments in the area, and identification of recorded archaeological sites and historic buildings in the area), and field investigations of the site (SWCA, 2017).

    Background research indicated that five archaeological sites have been previously recorded within a 1-mile radius of the site, including the former Columbia and Puget Sound Railroad site, the Potter’s Field Cemetery, the Comet Lodge Cemetery, the King County Crematorium and Columbarium, and a site along the Duwamish River in which skeletal remains were discovered (SWCA, 2017).

    Onsite investigations included a pedestrian survey of the entire project area and two transects with shovel probes, spaced at approximately 20-foot intervals (13 shovel probes total). Probes were extended from 1 meter to 2.3 meters below the ground surface, or at least 15 centimeters into glacial sediments when they were encountered. No significant cultural material was identified on the surface during the pedestrian survey or during the excavation of subsurface shovel probes. Soil profiles exhibited several layers of fill containing historical and modern debris, and indicate that spoils from the construction of Cleveland High School were used to level the field area, leading to shallower fill deposits along the base of the eastern slope and deeper fill deposits along the southwestern area of the site. As a result, it is anticipated that there is a very low potential for cultural resources to be found during construction activities for the proposed Cleveland High School Track and Field Improvements Project and no further cultural resource investigations are recommended (SWCA, 2017). See Appendix D for further details on the cultural resource assessment.

    c. Describe the methods used to assess the potential impacts to cultural and historic resources on or near the project site. Examples include consultation with tribes and the department of archeology and historic preservation, archaeological surveys, historic maps, GIS data, etc.

    Potential impacts to historic resources on or near the site were evaluated by consulting the City of Seattle Landmarks map and the Washington Information System for Architectural and Archaeological Records Data (WISAARD).

    In addition, as noted previously, a cultural resources assessment was completed for the project and included a review of existing documentation on the natural, cultural and historic setting of the site and surrounding area; a review of previous studies that were conducted in the project area; and, surface and subsurface investigations on the site, including 13 subsurface shovel probe excavations.

    d. Proposed measures to avoid, minimize, or compensate for loss, changes to, and disturbance to resources. Please include plans for the above and any permits that may be required.

    The following measure would be implemented to minimize cultural resource impacts:

    • Although archaeological resources are not anticipated on the site, it is possible that undiscovered pre-contact or historic cultural material is present within the project area. In the event of an inadvertent discovery, King County, the Washington State Department of Archaeology and Historic Preservation (DAHP) and affected Tribes (including the Duwamish) would be contacted. If construction encounters any human remains, whether burials isolated teeth, bones or mortuary items, work in that area would be stopped immediately and the area secured surrounding the discovery. Local law enforcement, DAHP and affected Tribes (including the Duwamish) would be contacted and no further excavation would occur until a process has been agreed upon by those parties.

    14. Transportation

    A Transportation Technical Report (Heffron Transportation, Inc., 2017) has been prepared for the proposed project and the results of the report are summarized in this section. For further details on the Transportation Technical Report, please refer to Appendix E of this Checklist.

    a. Identify public streets and highways serving the site or affected geographic area and describe the proposed access to the existing street system. Show on site plans, if any.

    The proposed Cleveland High School Track and Field Improvements Project site is generally accessed from 13th Avenue South via South Lucile Street. 13th Avenue South borders the western edge of the project site and dead-ends near the south end of the field area. The following provides a brief description of streets in the site vicinity.

    • 13th Avenue South – This street is a north-south Access Street that extends between South Spokane Street to the north and dead ends south of South Lucile Street adjacent to the project site. Near the project site, there is a sidewalk on both sides of the street and a curb along the north portion of the west side. Since there are no curbs along the east side of the street adjacent to the site, vehicles occasionally park at angles over the sidewalk.
    • South Lucile Street – This street is an east-west roadway that connects between Airport Way South and 18th Avenue South. The portion west of 15th Avenue South (adjacent to the site) is classified as a Minor Arterial; east of 15th Avenue South it is an Access Street. Near the site there is one travel lane in each direction with curb, gutter and sidewalk on both sides. There is a bike lane on the south (eastbound) side and no parking is permitted on either side of the street adjacent to the site.
    • 15th Avenue South – This street is a north-south roadway that provides access through residential neighborhoods east of I-5 between Golf Drive South and Swift Avenue South. It is classified as a Minor Arterial and has one travel lane in each direction with curb, gutter and sidewalk on both sides. Parallel on-street parking occurs on both sides of the street, with restrictions during certain times of the day.

    Access to the site would continue to be provided by 13th Avenue South, South Lucile Street and 15th Avenue South. It is anticipated that users of the field would utilize existing onsite off-street parking at Cleveland High School and on-street parking adjacent to the field along 13th Avenue South and in the surrounding area.

    b. Is site or affected geographic area currently served by public transit? If not, what is the approximate distance to the nearest transit stop?

    The site area is served by public transit with stops (one northbound and two southbound) located on 15th Avenue South. The northbound stop is located north of South Lucile Street. The southbound stops are located south of South Lucile Street and south of South Orcas Street. These stops are served by Metro Route 60 and Metro Route 107.

    Route 60 provides public transit service connecting Westwood Village, Georgetown, Beacon Hill, First Hill and Broadway. It operates from 5:00 AM to midnight with headways between 10 and 30 minutes. Route 107 provides service between Beacon Hill, Georgetown, Rainier Beach, Lakeridge, West Hill and the City of Renton. It operates from 5:00 AM to 1:00 AM with headways between 15 and 30 minutes.

    c. How many additional parking spaces would the completed project have? How many would the project or proposal eliminate?

    Existing on-street parking supply and demand counts were conducted in February and March of 2017 for streets in the vicinity of the project site (within an 800-foot walking distance from school site corners). Approximately 419 on-street parking spaces are located within the study area and of these spaces, 388 have no restrictions[11]. Parking demand counts were conducted in the evenings to reflect two conditions: early evening (between 5:45 PM and 6:45 PM) to reflect school-related athletic parking demand, and later evenings (between 8:15 PM and 9:15 PM) to reflect non-school related athletic parking demand (i.e. City of Seattle Parks and Recreation Department programs). Peak utilization of on-street parking during these time periods was 53 percent (223 vehicles parked in 419 parking spaces).

    In addition to on-street parking, there are two off-street parking lots on the Cleveland High School site. A north lot, located west of the building and accessed from South Lucile Street, contains 16 striped parking spaces including 3 with restrictions (disabled permits and school staff). A south lot is located to the south of the school building and is accessed from 15th Avenue South. This lot contains 111 striped spaces, including 16 with restrictions. Parking demand counts were performed for these onsite parking lots on the same dates and times as the on-street demand counts and indicated that demand in the two parking lots combined ranged from 3 to 27 vehicles (with a maximum utilization of 21 percent). On average, 114 off-street parking spaces were unused during weeknight counts and 122 off-street parking spaces were unused during weekend counts.

    To evaluate parking demand for the proposed Cleveland High School Track and Field Improvements Project, average attendance for school athletic activities and non-school athletic activities from similar local facilities were utilized, along with their associated parking demand. Average attendance for school athletic activities is anticipated to range from 118 to 135 people per event, while non-school athletic activities would range from 50 to 60 people per event. With an observed parking demand rate ranging from 0.6 to 0.7 vehicles per person, it is anticipated that peak parking demand for school-related athletic activities would be 100 to 140 vehicles during the short period between activities (between 5:15 PM and 5:45 PM and again between 6:45 PM and 7:15 PM). Outside of the short peak times, parking demand would be expected to range from 30 to 95 vehicles.

    As noted previously, within the off-street parking lots at Cleveland High School there are an average of 113 unused parking spaces on weekday evenings and 122 unused parking spaces on weekend evenings, which would accommodate the demand from individual athletic activities at the field. However, field users may find on-street parking to be more convenient (particularly along 13th Avenue South) due to walking distances. During the short early-evening period between consecutive activities there would be some demand for on-street parking, and parking along 13th Avenue South may be high or full during those periods (particularly adjacent to the field). The combination of unused off-street parking and unused on-street parking in the larger study area would be able to accommodate the project-related demand. However, it is recommended that Seattle Public Schools and the Seattle Parks and Recreation Department encourage field users to park in off-street parking areas and provide walking directions and signage to the field (see Appendix E for further details on parking).

    d. Will the proposal require any new or improvements to existing roads, streets, pedestrian, bicycle or state transportation facilities, not including driveways? If so, generally describe (indicate whether public or private).

    The proposal will not require any new streets or significant street improvements.

    e. Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe.

    The project site is located west of one of Seattle’s major industrial areas along the Duwamish River, which includes the Union Pacific Railroad and Boeing Field/King County International Airport. However, water, rail, or air transportation would not specifically serve the project.

    f. How many vehicular trips per day would be generated by the completed project or proposal? If known, indicate when peak volumes would occur and what percentage of the volume would be trucks (such as commercial and non-passenger vehicles). What data or transportation models were used to make these estimates?

    Cleveland High School currently generates traffic during the PM peak hour (5:00 PM to 6:00 PM) and early evening hour (6:00 PM to 7:00 PM), including 53 trips (11 in and 42 out) during the PM peak hour and 22 trips (6 in and 16 out) during the early evening hour. Traffic generated by high schools during the PM peak hour and early evening hour may be related to student activities such as athletics or other extracurricular activities, or they may be related to community use of the school (i.e. community use of the gymnasium or use of meeting spaces for groups such as Boy Scouts or Girls Scouts).

    As shown in Table 1, all of the intersections within the study area currently operate at acceptable levels of service with signalize intersections operating at LOS C or better and unsignalized intersections operating at LOS B or better during the PM peak and every evening hours. These conditions would be expected to continue by 2019 without the proposed Cleveland High School Track and Field Improvements Project.

    Construction activities for the proposed Cleveland High School Track and Field Improvements Project are anticipated to begin in June 2018 and would be completed by November 2018. The construction effort would include earthwork activities consisting of approximately 1,810 cubic yards of cut and exported material and the import of approximately 4,000 cubic yards of aggregates and other bulk materials. The more intensive portion of the effort would be the import and delivery of materials which is estimated to require approximately 175 truck trips. The highest volume of truck traffic would likely occur in July and August and while these volumes would be noticeable to nearby residents, it would not be expected to result in significant impacts to traffic operations.

    Construction would also generate employee and equipment trips to and from the site with construction crews generally consisting of 12 or fewer workers at a given time. The largest number of workers onsite would occur during specialty work associated with the synthetic track and rubberized surface. During summer months, when school is not in session, some parking for construction personnel could occur in the north parking lot of Cleveland High School, although some workers could also park along 13th Avenue South.

    The development of the proposed Cleveland High School Track and Field Improvements Project would allow school athletic activities that are currently held elsewhere due to poor field conditions, field conflicts and darkness to be held at the site. These activities would result in new trips being generated during the PM peak hour and early evening hour. Use of the fields for non-school-related athletic activities such as Seattle Parks and Recreation Department programs would also result in increased usage of the field until approximately 11:00 PM. It is anticipated that increased usage of the field for school athletic activities and non-school-related athletic activities would generate approximately 85 vehicle trips during PM peak hour when school athletic activities are ending and non-school-related activities are beginning. During the early evening hour, approximately 60 vehicle trips would be generated during non-school-related activities.

    Future traffic operations were analyzed with and without the proposed project and while additional traffic from the project would add some delay at intersections, it is anticipated that all intersections would operate at without-project levels (LOS C or better). See Table 2 for a summary of future traffic operations with and without the project.

    Based on the results in Table 2, it is anticipated that the proposed Cleveland High School Track and Field Improvements Project would not result in significant adverse impacts to traffic operations in the site vicinity (see Appendix E for further details on traffic operations).

    g. Will the proposal interfere with, affect or be affected by the movement of agricultural and forest products on roads or streets in the area? If so, generally describe.

    The project would not interfere or be affected by the movement of agricultural and forest products on the roadway network near the site area.

    h. Proposed measures to reduce or control transportation impacts, if any.

    The proposed Cleveland High School Track and Field Improvements Project is not anticipated to result in significant adverse impacts to traffic or parking in the site vicinity. However, the following measures would help to minimize parking-related impacts of the project, particularly along 13th Avenue South, adjacent to the site.

    • Seattle Public Schools and Cleveland High School would ensure that off-street parking lots are open and available for users during all times that the field is being used.
    • In materials that provide directions to the field, Seattle Public Schools and the Seattle Parks and Recreation Department would include directions to off-street parking lots at Cleveland High School.
    • Signage would be provided at or near 13th Avenue South that directs drivers to off-street parking lots and signage for pedestrians from the parking lots to the field (e.g. walkways along the west side of the school building).
    • Seattle Public Schools would work with SDOT to identify measures that can be implemented to minimize the potential parking-related impacts along 13th Avenue South. Possible options that could be explored include:
      • Adding signage directing field users to onsite parking lots at Cleveland High School;
      • Formalizing angle parking along the east side of 13th Avenue South adjacent to the site to maximize supply;
      • Provide pre-fabricated concrete curb sections to prevent parking across walkways;
      • Improve the southern street end, including no parking signage, to provide adequate turnaround space; and,
      • Assist residents who desire to paint driveway curb edges with yellow paint.

    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.

    While the completed Cleveland High School Track and Field Improvements Project would result in increased use of the playfield which could result in some injuries due to athletic activities and uses, it is not anticipated to generate a significant increase in the need for public services. To the extent that emergency service providers have planned for gradual increases in service demands, no significant impacts are anticipated.

    Proposed measures to reduce or control direct impacts on public services, if any.

    While the potential increase in use associated with the proposed project may result in incrementally greater demand for emergency services, it is anticipated that adequate service capacity is available within the Beacon Hill area to preclude the need for additional public facilities/services.

    16. Utilities

    a. Circle utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary sewer, septic system, other.

    All utilities are currently available at the 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 immediate vicinity that might be needed.

    Utilities and providers (in parentheses) proposed for the Cleveland High School Track and Field Improvements Project would include the following:

    • Water – for irrigation and stormwater collection (Seattle Public Utilities).
    • Electrical – for the proposed field lighting (Seattle City Light).
