SEPA Environmental Checklist
Purpose of checklist
Governmental agencies use this checklist to help determine whether the environmental impacts
of your proposal are significant. This information is also helpful to determine if available
avoidance, minimization, or compensatory mitigation measures will address the probable
significant impacts or if an environmental impact statement will be prepared to further analyze
the proposal.
Instructions for applicants
This environmental checklist asks you to describe some basic information about your proposal.
Please answer each question accurately and carefully, to the best of your knowledge. You may
need to consult with an agency specialist or private consultant for some questions. You may use
“not applicable” or “does not apply” only when you can explain why it does not apply and not
when the answer is unknown. You may also attach or incorporate by reference additional studies
reports. Complete and accurate answers to these questions often avoid delays with the SEPA
process as well as later in the decision-making process.
The checklist questions apply to all parts of your proposal, even if you plan to do them over a
period of time or on different parcels of land. Attach any additional information that will help
describe your proposal or its environmental effects. The agency to which you submit this checklist
may ask you to explain your answers or provide additional information reasonably related to
determining if there may be significant adverse impact.
Instructions for lead agencies
Please adjust the format of this template as needed. Additional information may be necessary to
evaluate the existing environment, all interrelated aspects of the proposal and an analysis of
adverse impacts. The checklist is considered the first but not necessarily the only source of
information needed to make an adequate threshold determination. Once a threshold
determination is made, the lead agency is responsible for the completeness and accuracy of the
checklist and other supporting documents.
Use of checklist for nonproject proposals
For nonproject proposals (such as ordinances, regulations, plans and programs), complete the
applicable parts of sections A and B, plus the Supplemental Sheet for Nonproject Actions (Part D).
Please completely answer all questions that apply and note that the words "project," "applicant,"
and "property or site" should be read as "proposal," "proponent," and "affected geographic area,"
respectively. The lead agency may exclude (for non-projects) questions in “Part B: Environmental
Elements” that do not contribute meaningfully to the analysis of the proposal.

This proposal is for improvements to the existing baseball and softball fields at Lindbergh High
School, which will enhance the usability of the fields. Lindbergh High School is three parcels and
about 37 acres in size. The various improvements in this proposal are occurring on an approximately
5.73 acre area including the baseball and softball fields and the direct vicinity.
This includes converting the existing ball field surfaces of natural turf and the clay/silt infields to
synthetic turf, with associated underground stormwater detention systems, similar to Rainvault. The
fill material proposed is cork and sand infill.
Also proposed is a new Musco field lighting system with 10 new light poles (four on the softball field,
and six on the baseball field), with pole heights of 60-90 feet and “full cutoff” housing, LED fixtures
and virtually no light spill to the surrounding areas.
SEPA Environmental checklist September 2023 Page 4
(WAC 197-11-960)
Also proposed is a new batting cage structure with roofing, chain-link fencing along the batting area,
and a storage area with garage style doors. The total roof coverage of the proposed structure is
approximately 40’ by 100’ or 4,000 square feet, while only 800 SF is enclosed.
The School District may complete the following projects as well if the funding allows and they are
included in the scope of this SEPA checklist:
• Larger dugouts with similar design, for ADA compliance.
• New concrete pads with space for 2 portable toilets per field. At this stage, only the concrete
pad is in the scope.
• Additional hardscaping for spectator access.
• An additional batting cage facility adjacent to baseball field.
• New scoreboards for both fields.
• A Public Address system with portable equipment and up to two permanently mounted
weatherproof speakers on each field backstop.

Environmental Elements
1. Earth
a. General description of the site:
Circle or highlight one: Flat , rolling, hilly, steep slopes, mountainous, other:
b. What is the steepest slope on the site (approximate percent slope)?
The project area is relatively flat, as it is currently used for athletic fields. The larger Lindbergh
High School site does have some portions of regulated slopes (as per COR GIS mapping),
generally sloping from east to west, with the steepest slopes indicated at 40-90% along the
western perimeter of the site. There are also some areas of the site, between school structures,
having slopes of between 15-40%, mostly closer to 15%. According to the 2001 Geotechnical
Report, the baseball field slopes downward to the north, with approximately five feet of
elevation difference between the backstop and the outfield fence, while the softball field has a
similar slope and elevation difference of six feet. In 2001 when the fields were improved, there
was grading done and retaining walls installed between the fields to accommodate a slope and
elevation difference between the baseball and softball field.
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.
Per the United States Department of Agriculture (USDA) soil map survey, the site consists of 40%
Alderwood gravelly sandy loam; 22.5% Arents, Alderwood material. The survey describes the
soils being formed from the weathering of glacial sediments, which is also generally consistent
with on-site exploration observations. A Geotechnical Report was prepared in 2001 specifically
for the athletic fields at Lindbergh High School. The results of AESI’s exploratory field samples
indicate “fill materials overlying natural deposits consisting of dense to very dense, silty gravelly
sand interpreted as lodgement till.”
d. Are there surface indications or history of unstable soils in the immediate vicinity? If
so, describe.
According to King County iMap, a small portion on the southeast side of the site, on which there
are no buildings, is flagged as a potential seismic hazard area. There are no other known
indications of unstable soils on or in the immediate vicinity of the site.
e. Describe the purpose, type, total area, and approximate quantities and total
affected area of any filling, excavation, and grading proposed. Indicate source of fill.
The conversion of the natural turf to synthetic turf of the fields, and associated site
improvements are expected to generate approximately 13,000CY of cut and an approximate
SEPA Environmental checklist September 2023 Page 7
(WAC 197-11-960)
equivalent amount in fill, including required stormwater detention volume located under the
field surface. Exported fill material will be disposed of at a permitted fill site, and imported fill
with be from a combination of permitted sand and gravel, composting facilities and
manufactured materials. Any export and import of material will be compliant with City of
Renton regulations.
f. Could erosion occur because of clearing, construction, or use? If so, generally
describe.
Erosion could occur during construction activities associated with grading, filling, and excavating.
To minimize potential erosion impacts, a Temporary Erosion Control Plan (TESC) will be
prepared as part of the site development plans for each phase of development. The TESC will
include construction procedures and best management practices.
g. About what percent of the site will be covered with impervious surfaces after
project construction (for example, asphalt or buildings)?
With the conversion of the softball and baseball fields to synthetic turf, the parcel is
approximately 57% impervious, including existing and proposed underdrained sports fields.
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if
any.
During construction, temporary erosion and sediment controls will be used to ensure earthwork
does not cause any erosion impacts. A Temporary Erosion and Sediment Control Plan will be
submitted as part of the grading/site development permit application. All TESC measures would
conform to the Washington State Department of Ecology BMPs, as well as City of Renton
regulations.
2. Air
a. What types of emissions to the air would result from the proposal during
construction, operation, and maintenance when the project is completed? If any,
generally describe and give approximate quantities if known.
Construction activities have the potential to create temporary dust emissions during earth-
moving activities and exhaust emissions due to the combustion of gasoline and diesel fuels. Dust
and exhaust emissions are expected to be minimal, localized, and temporary. After construction,
no additional emissions to air are anticipated to result from the proposal.
b. Are there any off-site sources of emissions or odor that may affect your proposal? If
so, generally describe.
SEPA Environmental checklist September 2023 Page 8
(WAC 197-11-960)
There are no known off-site air emissions or odors that may impact the proposal.
c. Proposed measures to reduce or control emissions or other impacts to air, if any:
During construction temporary measures will be applied where necessary, which may include
limiting the idling of construction equipment, water sprays to control dust, limiting vehicle
speeds, and general maintenance of construction equipment.
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.
No, there are no surface water bodies on site. A large wetland area associated with
Molasses Creek is at its closest about 300 feet away from the edge of the Lindbergh High
School parcel. Molasses Creek is a tributary of the Cedar River, running east of the Lindbergh
High School site. No effects to the wetland are expected as a result of this proposal.
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.
No, the project does not require any work over, in, or adjacent to surface waters. The
project site is on the opposite side of the Lindbergh campus from Molasses Creek, about .25
miles away.
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 will be placed in or removed from surface water.
4. Will the proposal require surface water withdrawals or diversions? Give a
general description, purpose, and approximate quantities if known.
No, surface waters will not be withdrawn or diverted as a result of this proposal.
5. Does the proposal lie within a 100-year floodplain? If so, note location on the
site plan.
No, the site is within neither a 100, nor a 500-year floodplain. According to FEMA FIRM
panel 53033C0983G, revised 2017.
SEPA Environmental checklist September 2023 Page 9
(WAC 197-11-960)
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.
No, the proposal does not involve any discharges of waste materials to surface waters.
b. Ground:
1. Will groundwater be withdrawn from a well for drinking water or other
purposes? 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 a general description, purpose, and approximate quantities if
known.
No groundwater will be withdrawn nor will water be discharged to groundwater. Public
water is provided to the site by the City.
2. Describe waste material that will be discharged into the ground from septic
tanks or other sources, if any (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.
There will be no waste material discharged into the ground as a result of this proposal. The
site is on City sewer.
c. Water Runoff (including stormwater):
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 source of runoff is from stormwater. Stormwater is regulated under the jurisdiction of
the City of Renton, and stormwater improvements will be designed in accordance with the
2022 City of Renton Surface Water Design Manual, which follows the 2021 King County
Surface Water Design Manual. Stormwater from rainfall will be collected with a subsurface
drainage system, consisting of lateral perforated pipes that drain to a main collector pipe in
each field. The underdrain system will bring stormwater to a detention system for flow
control. From the flow control system, it is expected that the outlet will connect to the
existing storm line in the fire lane north of the fields. Stormwater will follow the existing
downstream path in a piped system, eventually discharging into Ginger Creek approximately
0.8 miles from the school site. The detention system will provide approximately 87,000
cubic feet of detention, but is subject to change as the project continues through the design
and permitting process.
SEPA Environmental checklist September 2023 Page 10
(WAC 197-11-960)
On the Lindbergh High School site there are two distinct drainage systems, which divide the
site into two threshold discharge areas- Ginger Creek to the north and Molasses Creek to
the south. Both ultimately drain to the Cedar River watershed.
This proposal will require full drainage review by the City of Renton.
2. Could waste materials enter ground or surface waters? If so, generally describe.
No waste materials will enter ground or surface waters as a result of this proposal.
3. Does the proposal alter or otherwise affect drainage patterns in the vicinity of
the site? If so, describe.
The proposal will not alter existing drainage patterns, runoff from the site will continue
to drain in existing patterns.
d. Proposed measures to reduce or control surface, ground, and runoff water, and
drainage pattern impacts, if any:
Flow control is required for this project, and it is anticipated to be addressed with a modular
stormwater detention system located beneath the baseball field, which will utilize a flow control
structure that attenuates flow as necessary. The rough calculations for stormwater detention
with the conversion of the grass fields to synthetic turf for both fields is approximately 87,000
cubic feet. Water quality treatment will be provided to meet City of Renton requirements.
4. Plants

SEPA Environmental checklist September 2023 Page 11
(WAC 197-11-960)
☐ other types of vegetation
b. What kind and amount of vegetation will be removed or altered?
There are no trees or vegetation other than lawn grass within the project area, as the existing
area is used for athletic fields. The fields will be reconditioned by removing the existing top 3-
inches of sod, material, and debris and replacing it with new material (cork and sand- 0 to 5
inches in depth) to improve field drainage and prevent rainouts and field closures.
c. List threatened and endangered species known to be on or near the site.
No threatened or endangered species have been identified on the site itself. According to the
Washington Department of Fish and Wildlife’s PHS on the Web mapping tool, resident coastal
cutthroat trout has been spotted in the wetland associated with Molasses Creek, just to the
southeast of the larger Lindbergh High School site.
d. Proposed landscaping, use of native plants, or other measures to preserve or
enhance vegetation on the site, if any.
Other than in kind restoration, there is no landscaping proposed as part of this project.

There are no known invasive animal species on or near the site.
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.
Any electrical use would be provided by Puget Sound Energy. The batting cages, field lights and a PA
system would all use electricity to operate. Field lighting will utilize LED lights.
b. Would your project affect the potential use of solar energy by adjacent properties?
If so, generally describe.
No, the project will not have an impact on potential use of solar energy on adjacent
properties.
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.
Field lights will use LED bulbs, which provide an energy savings of roughly 70% when
compared to an HID lighting system.
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 because of this
proposal? If so, describe.
Environmental health hazards, including exposure to toxic materials, could occur during the
course of this project; this includes accidental spills of hazardous materials from equipment,
and vehicles. A spill prevention and control plan will be developed to prevent the accidental
release of contaminants into the environment.
1. Describe any known or possible contamination at the site from present or past
uses.
Currently, no contaminants are known to exist at Lindbergh High School. The school
undertook a modernization project in 2024, which included the removal of hazardous
SEPA Environmental checklist September 2023 Page 13
(WAC 197-11-960)
building materials including asbestos, lead paint, mercury-containing fluorescent light
tubes and some PCB-containing light ballasts.
Department of Ecology lists an on-going clean-up related to an underground petroleum
storage tank that was used to power the furnace. The tank was removed, and the soil
remediated in 2016.
The Tacoma Smelter Plume map shows the site as being demarcated as under 20 ppm
category for asbestos- the lowest risk.
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.
Per the National Pipeline Public Mapping System, there is a gas transmission pipeline
located about .25 miles to the north of the site (offsite), running just south of SE 160th
Street.
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.
The proposal does not involve the storage or use of toxic or hazardous chemicals, with the
exception of some petroleum use during construction.
4. Describe special emergency services that might be required.
No additional special emergency services will be required other than those normally
provided such as police, emergency medical, and fire protection.
5. Proposed measures to reduce or control environmental health hazards, if any.
Any soils contaminated by spills would be excavated and disposed of in a manner
consistent with the level of contamination and in accordance with federal, state, and local
regulatory requirements.
b. Noise
1. What types of noise exist in the area which may affect your project (for example:
traffic, equipment, operation, other)?
The site is located in a primarily single family neighborhood, with the noise associated
with suburban residential and traffic levels.
SEPA Environmental checklist September 2023 Page 14
(WAC 197-11-960)
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)?
The operation of trucks, excavators, and front-end loaders will likely result in temporary
noise and vibration impacts during construction.
A Public Announcement (PA) system is planned that would provide some instances of
noise related to games. The type of system that has been used in other area high schools
and is modeled for this proposal includes two permanent waterproof speakers mounted
near the backstop of each field. The average decibel level of these speakers ranges from
about 80-100 decibels. The PA system would only by utilized during games to announce
players and scores and would not be used after 10pm.
3. Proposed measures to reduce or control noise impacts, if any:
No measures proposed for construction, as noise is expected to return to existing levels
one construction is complete. Should the PA system be utilized, the school would cease its
use after 10pm.
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 current use of the site is Lindbergh High School. The school was constructed in 1970 and
has remained in use since that time. The project area is currently used for athletic fields.
Adjacent properties are single family residential uses to the north, west and east. To the
south is Renton Park Evangelical church and a large area of forested open space called
Renton Park, about 17 acres of which belongs to King County Parks. The proposal will not
impact current land uses onsite or to nearby properties.
b. Has the project 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 because 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 subject property has not recently been used as working farm or forest lands.
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?

specify.
The city cites regulated slopes on the site, nearby wetlands, and the county lists an area on
the southeast portion of the site as a seismic hazard.
i. Approximately how many people would reside or work in the completed project?
The proposal is for field improvements and will not result in a change to enrollment or staffing
numbers at Lindbergh High School.
j. Approximately how many people would the completed project displace?
The project will not result in the displacement of people.
k. Proposed measures to avoid or reduce displacement impacts, if any.
SEPA Environmental checklist September 2023 Page 16
(WAC 197-11-960)
No measures are proposed as displacement will not result from the proposal. Any athletic
events that might occur during construction would be relocated to other facilities.
l. Proposed measures to ensure the proposal is compatible with existing and projected
land uses and plans, if any.
None proposed as the proposed use is the same as the existing and will be compatible with
existing land uses.
m. Proposed measures to reduce or control impacts to agricultural and forest lands of
long-term commercial significance, if any:
None proposed, as the proposal is not likely to result in any impacts to agricultural and forest
lands.
9. Housing
a. Approximately how many units would be provided, if any? Indicate whether high,
middle, or low-income housing.
No housing will be provided as part of this proposal.
b. Approximately how many units, if any, would be eliminated? Indicate whether high,
middle, or low-income housing.
No housing will be eliminated as part of this proposal.
c. Proposed measures to reduce or control housing impacts, if any :
None proposed, as the proposal will not impact housing.
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 tallest proposed structure for the project are the proposed new lighting poles, with the
tallest being 90 feet in height.
b. What views in the immediate vicinity would be altered or obstructed?
The views will be the same as existing, with the exception of the 10 new light poles.
SEPA Environmental checklist September 2023 Page 17
(WAC 197-11-960)
c. Proposed measures to reduce or control aesthetic impacts, if any:
Street trees have been planted around the perimeter of the fields along the portion that abuts
residences. No other measures are proposed or necessary.
11. Light and glare
a. What type of light or glare will the proposal produce? What time of day would it
mainly occur?
New field lighting will be present on the softball and baseball fields when they are in use from
dusk until approximately 10pm during the winter/darker months. The lighting has been
designed to minimize light spillage to adjacent areas.
b. Could light or glare from the finished project be a safety hazard or interfere with
views?
No safety hazards are expected due to light or glare from this proposal. Per the site lighting
analysis prepared by Musco, very limited light spill will occur to the neighboring properties; in
only one instance light spill registers at .2 footcandles.
c. What existing off-site sources of light or glare may affect your proposal?
There are no off-site sources of light that affect this proposal.
d. Proposed measures to reduce or control light and glare impacts, if any:
Lighting fixtures will be LED, full cutoff type and shielded to prevent light spillage. The light
fixtures will be calibrated and optimized after installation and aimed towards the field in order
to maximize playability and minimize light spill. Field lights will only be turned on during field
use, and not in use after 10pm.
12. Recreation
a. What designated and informal recreational opportunities are in the immediate
vicinity?
The school property includes baseball and softball diamonds, football/soccer field and a
track. The school property also contains tennis courts and an indoor pool. South of Lindbergh
High School there is Renton Park Elementary school, which also contains baseball/softball
fields and a play structure. Adjacent to the southeast portion of the site is the heavily
wooded Renton Park, through which Molasses Creek runs, and there is also a hiking trail.
Fairwood Crest Community Park is nearby to the northeast.
b. Would the proposed project displace any existing recreational uses? If so, describe.
SEPA Environmental checklist September 2023 Page 18
(WAC 197-11-960)
The fields being renovated will not be accessible during construction which may temporarily
displace the recreation that occurs there. Once completed, the project will continue to
provide recreational opportunities on site and will provide upgraded softball and baseball
diamonds. The synthetic turf and lighting will allow for extended play during the winter
months.
c. Proposed measures to reduce or control impacts on recreation, including recreation
opportunities to be provided by the project or applicant, if any:
No proposed measures as the proposal is not negatively impacting any recreational
opportunities.
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? If so, specifically describe.
No historic sites are mapped on the Washington State Department of Archeology and Historic
Preservation (DAHP) Washington Information System for Architectural and Archeological
Records Data (WISAARD) Mapping on or near the site. The school building itself was
constructed in 1971-72 and therefore over 45 years old and documented on the DAHP
property listing.
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.
The entire Puget Sound region was once native territory, (in this case interested tribes include
the Squaxin, Suquamish, Muckleshoot, Tulalip and Snoqualmie). The WISAARD mapping
system identified the possible location, skirting the southwest portion of the site as a trail
from Seattle over the Cascade mountains.
However, the DAHP predictive model indicates that the Lindbergh High School site is split
between Low Risk and Moderately Low Risk for archaeological resources.
The District requested a DAHP review of the school for the previous modernization proposal,
under DAHP Project Tracking Code: 2021-12-08567. The DAHP concluded the school may be
eligible for listing in the National Register of Historic Places based upon one of the criterion of
the NRHP.

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.
The proposal utilized the Washington Information System for Architectural and Archaeological
Records Data (WISAARD) online database to assess potential impacts to cultural and historic
resources on and near the project site.
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.
No disturbance to cultural or historical resources is expected and no modifications to existing
buildings are proposed. The Washington State DAHP will be notified if any cultural or
archeological objects are found during work on the site. If cultural or archaeological resources
are found, then site work will stop until Washington State DAHP provides guidance.
14. Transportation
a. Identify public streets and highways serving the site or affected geographic area and
describe proposed access to the existing street system. Show on site plans, if any.
There are three automobile access points to Lindbergh High School off of 128th Ave SE, on the
west side of the site. Two are bi-directional and one is an egress only. 128th Avenue SE is
designated as a collector street, as is SE 164th St. on the north side of the site, although there
is a row of single-family homes between the school boundaries and SE 164th St.
Pedestrian access is via 5’ sidewalks along 128th, as well as several other pedestrian access
points- one on the northeast corner at SE 164th St, the southeast corner at SE 168th St. and the
south side at SE 168th St., which is a dead-end cul-de-sac.
b. Is the site or affected geographic area currently served by public transit? If so,
generally describe. If not, what is the approximate distance to the nearest transit
stop?
Yes, the site is served by King County Metro routes 102, Fairwood to Downtown Seattle and
148, Fairwood to Renton with stops on SE 168th St. Route 102 is a commuter route to
downtown Seattle and only has service during peak times. Route 148 has weekday service
with 30 minute frequency. Stops for both routes are about .5 miles from the site. Both have an
additional nearby stop.
School bus transportation is also provided by the District.

c. 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).
No, the proposal does not include improvements to existing roads. Frontage improvements
were made in association with the Lindbergh High School modernization project in 2022.
d. Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or
air transportation? If so, generally describe.
No, the project is not within the vicinity of water, rail, or air transportation.
e. 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 nonpassenger vehicles).
What data or transportation models were used to make these estimates?
The proposal will not result in any changes to the number of vehicular trips per day as it will
not increase the number of classrooms, enrollment or staffing. It is possible that trip patterns
will change in the winter months with the later available use of the fields. It is not anticipated
that there will be a change or increase of trips in the PM peak hour.
f. 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.
No, the proposal will not affect or be affected by the movement of agricultural or forest
products.
g. Proposed measures to reduce or control transportation impacts, if any :
None proposed or required as no additional trips are anticipated in the PM peak hour.
15. Public services
a. Would the project result in an increased need for public services (for example: fire
protection, police protection, public transit, health care, schools, other)? If so,
generally describe.
The project will not result in an increased need for public services other than those already
provided at the site.
b. Proposed measures to reduce or control direct impacts on public services, if any.
No proposed measures as the proposal is not likely to result in impacts on public service.
