MEMORANDUM
To: Steve Lancaster
From: Michael Jenkins
Date: January 4, 1999
Re: E98-0026, Thorndyke Elementary School, 4415 S. 150th Street
Project Description:
This SEPA review is for the construction of a 64,500 square foot school. The project is
designed to replace the existing school.
Agencies with jurisdiction:
None
Summary of Primary Impacts:
• Earth
Site is relatively flat in the construction area. Steepest portion of site is
approximately 50%. Approximately 4.5 acres of the site along the south portion of
the site include native vegetated slopes in excess of 20%, which will not be disturbed
as a result of this project. Any disruption of the site where slopes are greater than
20% requires compliance with the City's Sensitive Areas Ordinance (TMC 18.45).
Any trees removed in said slope will require compliance with the City's Tree
Ordinance (TMC 18.54).
Approximately 10,000 cubic yards of cut and fill will be required to create the new
building site. Erosion control will occur during clearing of site and building
construction to include a sediment ponds, fabric fencing and trenching. A Land
Altering Permit for movement of earth in excess of 50 cubic yards is required. 25%
of the site will include impervious surfaces. A geotechnical report was submitted by
the applicants on November 10, 1998
• Air
Dust will be generated during construction, with watering to control dust.
E98-0026 - Thorndyke School,
4415 S. 150th St.
January 4, 1999
• Water
Surface water runoff from impervious surfaces will be collected and treated on-site
prior to discharge to off-site systems. A catch basin system will be used. The storm
drainage system must comply with the city's storm water management ordinance and
the King County Surface Water Design Manual. For water quality and on-site
detention, a Wet Pond will be the dominate feature, located along the west portion of
the site. Some grading will occur to improve the function of the above ground
system. An off-site analysis including upstream and downstream drainage with
retention analysis may be required, as the drainage may filter into existing wetlands
and into various watersheds.
• Plants
In addition to the native and vegetated slopes previously mentioned, there are planted
grasses for play fields and ornamental vegetation around the site. The bulk of the
existing landscaping will be removed and a new landscape plan will be submitted as
part of the final approved plans. The landscape plan must be approved as part of the
Conditional Use Permit requirements. The wetpond will have landscape elements to
screen visual impacts and impede physical access.
• Animals
No known impact.
• Energy/Natural Resources
Electricity and/or natural gas will be used to heat proposed structure. The structure
must comply with the Washington State Energy Code.
• Environmental Health
No known environmental hazards. Noise will be generated both during construction
period and from traffic after project is completed. Construction activities must
comply with Tukwila's Noise Ordinance (TMC 8.22). A demolition permit from the
Puget Sound Air Pollution Control Agency (PSAPCA) will be required, which may
include specific requirements in case of on-site asbestos removal during the
demolition of the existing structures.
E98-0026 - Thorndyke School•
4415 S. 150th St.
January 4, 1999
• Land/Shoreline Use
The site is located in the Low Density Residential (LDR) zone. The site also includes
Public Recreation Overlay zoning classification, regulated under TMC 18.42. A
Conditional Use Permit is required. A variance will also be required, as portions of
the structure are in excess of the 30 foot height maximum for all uses in its zone.
Approval of a Lot Consolidation will be required prior to the issuance of any
Development Permits.
• Housing
No known impact.
• Aesthetics
The existing structures will be removed. Approval by the Board of Architectural
Review for this project is not required, although aesthetics may be part of the
Conditional Use Permit approval process. The project will require a variance, as
portions of the building exceed the 30 foot height limit for uses in this zone.
The predominate building materials include a Standing Seam Metal roof, Concrete
Masonry Unit (CMU) base and Fiberboard exterior walls. A landscape plan approved
by the Planning Commission is required.
• Light and Glare
A lighting plan has been submitted as part of the Conditional Use Permit. Pedestrian,
parking and architectural enhancement lighting will be included. Shields and/or
reflectors will be used on parking lot standards to avoid off-site impacts. Minimum
candle power requirements may be needed to ensure minimal off-site glare.
Adherence to Crime Prevention through Environmental Design (CPTED) standards
for placement, type and intensity of lighting may be required to minimized possible
off-site impacts and to ensure lighting adequately lights the site and reduces unlit or
improperly lit areas of the site.
• Recreation
The existing fields at the school will be rehabilitated and restored. The playfields will
be dual use for Soccer and Softball. The files will be designed primarily for use of
the school but may be used by School District sanctioned users and events.
E98-0026 - Thorndyke School •
4415 S. 150th St.
January 4, 1999
• Historic/Cultural Preservation
No impact.
• Transportation
65 parking spaces are proposed for the school. In addition, bicycle parking stalls for
both students and staff will be required. Completion of sidewalks between the site
and 42nd Ave S. will be included as part of the Capital Infrasturcture Program (CIP),
with an equivalent amount of the associated costs addressed by the school district. A
hauling permit for removal of debris following construction will be required, as well
as for construction vehicles and related activities. A Transportation Management
Plan will be required to address transportation impacts as a result of the construction
of the new school. A traffic impact analysis has been submitted along with grading
and paving plans. A traffic study may be required.
• Public Services
The facility may require fire and police protection as well as emergency services.
CPTED standards concerning lighting, off-site visibility and access to the school have
been reviewed and addressed by the Tukwila Police Department as part of this
review.
• Utilities
The site is served by the City of Tukwila Sewer and Water utilities. Electric, gas and
telephone services will be secured
Recommendation:
•DNS
From: Gary Barnett
To: Michael
Date: 12/14/98 2:40pm
Subject: Thorndyke school street improvements require district contribution
Please note to the applicant that the school district will pay for the improvements done by the city. A developer
agreement will be entered into to allow deferal to CIP with cost sharing by the district. This arrangement has been
done on other school project adjacent to CIP projects.
Please communicate this in writing to the district to give the complete info regarding their obligation, so they are not
surprised at a later date. Your letter of December 10 could be interpretted to mean that the city has accepted the
full responsiblity for the street improvements. Many thanks, Gary

Re: Thorndyke Elementary School
Site Noise Measurements
Dear Tom:
r. --. 1
OCT - 9 i99 The
REENBUSCI—I
Group
This letter documents the results of acoustical measurements of noise levels at the
Thorndyke Elementary School site. The purpose of the measurements was to evaluate the
existing noise environment at the proposed site to determine whether the noise levels are
in conformance with State Public School Standards; WAC 246-366-030. In accordance
with the Washington code, noise levels at a school site should not exceed an hourly
average of 55 dBA (Leq 1 hr) and hourly maximum (Lmax) of 75 dBA during the time of day
the school is in session. A noise reduction plan to reduce the interior noise within the
school to acceptable levels should be included in the school design, if the measured site
noise levels exceed the limits imposed by the Code.
Measurement Description. A 24-hour measurement of existing noise levels was taken
during September 25,1998 at the proposed site. The measurements were conducted using
a Larson/Davis 700 type 2 integrating sound level meter. All measurements were
calibrated prior to and following data acquisition, with a Larson/Davis calibrator.
The following descriptors are used to characterize various components of sound:
Equivalent Sound Level (Lt21
Leq is a single -value description of average noise exposure over various specified time
intervals. The Leq is used to characterize complex, fluctuating sound levels with a single
number.
Maximum Level (Lmax
Lmax represents a maximum sound level measured during each one-hour period of time.
Statistical Noise Level (L,1211
The statistical descriptors are used to describe noise levels which fluctuate and represent
the sound that is exceeded the certain percentage of time (commonly indicated in

parentheses). The statistical sound levels describe how often a given sound level is
exceeded during the period of the measurement. For example, L(1) is the sound level
exceed 1% of the time in a given time interval. L(1) levels are generally used to represent
maximum levels for practical purposes. The L(90) noise level would be exceeded 90% of
the time, and is typically considered to represent the background noise level.
Measurement Results. The results of measurements are documented in Table 1. The
major noise sources on the site are traffic noise from nearby streets (South 150th Street and
42"d Avenue South), freeway traffic noise, and occasional aircraft noise. Our observation
of the existing sound environment showed that the major contributor to the maximum
noise levels represented in the table as Lmax. is aircraft noise. Freeway traffic noise raised
the background level represented by L(90) in the table below.

To determine the compliance with the Code regulations and establish the criteria for
exterior construction design, the table above presents the average Leq and Lmax sound
levels for the hours between 9 a.m. and 3 p.m. (time of day the school is in session).
An acceptable level of 30 dBA for interior intruding noise is determined based on the
following assumptions:
(1) The limit of 55 dBA for hourly average exterior noise level (Leq) during the time of
the day when the school is in session as established by the WAC 246-366-030.
(2) The limit of 75 dBA for maximum levels (Lmax) during the time of the day when the
school is in session as established by the WAC 246-366-030
(3) A typical northwest building construction which meets current energy codes
provides a noise level reduction of 25 dB.

` The measured noise levels of hourly Leg exceed the limit of 55 dBA imposed by WAC by
2.5 dBA and the measured maximum sound levels (Lmax) exceed the WAC limits of 75
dBA by 4 dBA. These exceedances of the existing noise levels at the proposed site will
result in an increase of the required noise reduction for the exterior construction.
Recommendations. The following recommendations represent guidelines for design of the
exterior construction. The recommendations are based on the measurement results of the
existing noise environment on the proposed site and design noise criteria of 30 dBA for
interior noise levels within the school intruding from outside. Since maximum noise
levels measured at the site are mostly due to aircraft noise, the spectrum of aircraft noise
(measured by the Greenbusch Group for unrelated projects) is also taken into account for
these recommendations.
Exterior Walls:.
Exterior walls should have a laboratory sound transmission class rating of at least 44.
Wood stud walls should be at least 4 inches in nominal depth and should be finished on
the outside with fiber cement plank siding or masonry veneer. Interior surface of the
exterior wall should be of gypsum board of at least 5/8" thick. The gypsum board may be
installed rigidly to the studs if the exterior is cement plank siding or masonry veneer. If the
exterior side is siding -on -sheathing, double thickness of 5/8" gypsum boards on the
interior side is required.
Exterior Windows:
The total area of glass should not exceed twenty percent of the floor area. Glass of
double -glazed windows should be at least 1/4" thick. Panes should be separated by a
minimum 1/2" air space. Double -glazed windows should employ fixed sash or efficiently
weather-stripped operable sash.
Roof
Combined roof and ceiling construction should have a laboratory sound transmission class
rating of at least STC -44. With an attic or rafter space at least 6" deep, and with a gypsum
board ceiling below, the roof should consist of 3/4" composition board, plywood or
gypsum board sheathing topped by roofing as required. Ceilings should be substantially
airtight with a minimum number of penetrations. Glass fiber insulation should be
provided above the ceiling between joists. Gravity vent openings in the attic should not
exceed code minimum in number and size. The openings should be fitted with transfer
ducts at least 3 feet in length containing internal sound absorbing duct lining. Each duct
should have a lined 90 degree bend in the duct such that there is no direct line of sight
from exterior through the duct into the attic.

Expected Interior Noise Levels
Page 4
The intruding sound levels with the described exterior construction are expected to be in
the range between 25 dBA and 28 dBA, depending on the outside noise levels in
accordance with measured hourly average Leq levels (Table 1). The intruding levels can
achieve as high as 45 dBA when the exterior levels reach the maximum levels associated
with aircraft noise (as high as 79 dBA). However, it should be noted that the maximum
levels according to a measurement procedure last no longer than 1 second. The better
representative for practical purposes is a statistical level L1 which is a level that would be
exceeded 1% of the time, i.e. 36 seconds for a one-hour period. The measured average
statistical sound level L1 is 63 dBA for a period of time when the school is in session. This
exterior level corresponds to a 33 dBA level of interior noise. In terms of NC criteria, this
level corresponds to NC 28 which is 7 points lower than the designed noise criteria
required by WAC for noise from a mechanical system. Consequently, background noise
in the classrooms which is typically associated with mechanical system noise will mask
the intruding noise which is not expected to be objectionable.
Please feel free to call if you have any further questions.
Sincerely,

Date: February 25, 1997
Prepared for: South Central School District (Security Advisory Committee)
Prepared by: R. W. Abbott, Tukwila Police Crime Prevention
Street Entrance:* The school's street address is not posted. It should be
readily visible as one drives up to the property, lighted if
possible.
Signing: * Property is not posted for "No Trespassing". The signing
is required for participation in the Tukwila Criminal
Trespass Program.
* All wooden signs (school name, office identification) are
faded and difficult to read.
* There is no sign advising visitors to register at the office.
* Review signing - there is a profusion of "Weapon Free"
signs, many posted in unlikely places, and a lack of other
necessary sign types, e.g. "Drug Free Zone".
* "No Parking - Bus Loading Zone" sign in front of the
'office is very faded and stained with obscene graffiti.
Lighting: * Light (wall mounted) on the north side of the west
building is misdirected, blinding those approaching . This
makes the building difficult to see and can obscure
vehicular and pedestrian traffic.

•
Lighting (Continued)
* Light in the entrance driveway is partially blocked by
trees. Pruning should allow the light to flood the entire
driveway.
* Five of the six lights in the Northwest breezeway are not
functioning.
* Southwest parking area needs a pole mounted light.
Landscaping: * Trees and shrubs are remarkably well pruned and
maintained, allowing clear vision of doors, windows, play
areas and parking lots.
Bicycle Storage:* The bike rack (on the west side of the gym) is not
visible from any of the offices or interior walkways.
Consider moving it to the north side of the gym where it
can be observed from the office or administration hallway.
Paved Areas: * The driveways and the parking lots have faded markings
for fire lanes and bus areas. Consider repainting. In some
cases, the markings are obscured by an accumulation of
tree debris (leaves and needles).
* The two -by four expansion joints in the sidewalks have
rotted away, causing gaps that may pose a "stumble"
hazard.
* Large pothole in driveway near office is a hazard to foot
and vehicular traffic.
Buildings: * The doors appear to have adequate locks that can be
secured from the inside. Assure that all adult personnel
have access to the "Allen" keys to secure the doors in case
of emergency "lock -down".
* Review facility key control. Know who has them, and re -
key if necessary.
CP'TGD Page 2
* Roof access:
> The fence on the north side of the complex
between buildings allows easy roof access for the
agile. Consider a roof mounted physical barrier to
deter climbers.
> The tree on the southeast side of the gym allows
easy roof access to that building. Consider pruning
the tree to deter climbers.
* The storage building/container on the south side of the
gym is stained with obscene and gang graffiti. Paint with a
heavy primer paint (may be available through the Police
Department).
* Alarm system: The system should be equipped with a
"panic button" feature available to the office staff. Training
on the appropriate use of this feature should be given to all
personnel who work in the office, and is available through
the Police Department Crime Prevention Unit.
Planning: * A contingency plan should be drawn which anticipates
violence emergencies (e.g. suspicious persons on campus,
hostage situations, lock -downs, evacuations, etc.).
Training: * Staff should be thoroughly trained in above plan.
Drill: * Both the staff and student body should be drilled on the
above plan, much as they are on fire or earthquake
emergencies.
Miscellaneous:* The picnic table on the north side of the parking area is
in an advanced state of disrepair. It should be fixed or
removed.
