III. FINDINGS
The Hearing Examiner has heard testimony, admitted documentary evidence into
the record, and taken this matter under advisement.
The Community Development Staff Report sets forth general findings, applicable
policies and provisions in this matter and is hereby marked as Exhibit "1" and
hereby incorporated in its entirety by this reference.
All appropriate notices were delivered in accordance with the requirements of the
Federal Way City Code (FWCC).
The applicant has a possessory ownership interest in a rectangular, 4.79 acre parcel
of partially improved property located in the southwestern portion of the City at SW
352"d Street'between 21't Avenue SW and 19t~ Avenue SW.
The applicant is requesting Preliminary Plat approval to subdivide the site into 21
single-family residential lots. All existing structures on the site are to be removed
before approval of the final plat.
An environmental Determination of Nonsignificance was issued for this proposed
action on September 4, 1999. One letter was submitted before the comment
deadline period. No appeals were received and the SEPA determination has not
been modified as of the date of this decision.
Zoning for the site and the property to the north, east and south is RS7.2. There are
apartments located to the west, across the street from 21't Avenue SW which are
zoned RM1800. The proposed density appears to be consistent with adjacent land
uses and zoning.
The site is slightly sloping from the southwest and southeast corners to the center
of the plat near the property line. The plat is located within a very shallow drainage
channel of a large basin. A grading utilities map submitted with the application
depicts the site with 0-4 percent slopes. The westerly one-third of the site is
developed residentially and the easterly two-thirds is used as pasture for large farm
animals. No significant wildlife exist on the site. The site has been 'cleared for
residential and pasture use and is surrounded by single-family residences. The plat
will be subject to approval of a landscape plan pursuant to Federal Way City Code
Section 20-158. Dudng the final plat design and review staff will work with the
applicant to identify trees that shall be retained on site. There are 27 existing
Page - 3
significant trees on the subject site according to a landscape architect survey. The
applicant is proposing to preserve 8 significant trees, plant street trees and provide
landscaping as required by Federal Way City Code.
o
The lots will range in size from 7,200 square feet to 7,900 square feet. Proposed
lots are generally rectangular in shape. Six of the lots are flag lots and are in
conformance with Federal Way standards. Tract C is designated a storm water
tract and tract "A" is designated as street right-of-way improvement tract. Both of
these tracts will be dedicated to the City. Tract B will be designated as an open
space tract and Tract D will be designated as a landscape easement. Both of these
will be owned and maintained by the homeowners association.
10.
No geological hazards or sensitive areas exist on the site. A wetland determination
prepared by' B-12 associates concludes that there are no wetlands present on the
site.
11.
A review of the Preliminary Plat reveals that access will be provided by the westward
extension of 352"d Street SW from 19th Avenue SW.. Full street improvements
within a 50-foot right-of-way will be required for 352"d Street. A public pedestrian
access tract will be located between the proposed cul-de-sac at the end of 352"d
Street SW and 21't Avenue SW. It will be dedicated to and maintained by the
homeowners association. Pedestrian connections from the subject site to
Sherwood Forest Elementary School are currently substandard and unsafe. The
applicant has agreed to design and construct a pedestrian corridodsidewalk from
the subject site to the existing sidewalk located within the southern portion of 351't
Street east of 19t~ Avenue SW.
12.
Sidewalks will be provided along all lot frontages. A 5-foot wide concrete sidewalk
will be provided on the east side of 21't Avenue SW. The applicant's proposed
pathway from the end of the cul-de-sac on 352"~ Street to 21't Avenue shall be 8-
foot in width and landscaped on either side. The applicant will provide full street
improvements along SVV 356~ Street which will include 28~feet of pavement, vertical
curbs, gutters, sidewalks, street lights and street trees within a 50-foot right-of-way
width as shown on the applicant's plat. In addition, 21st Avenue arterial will be
widened and improved, including tapers, with paving, a 6-foot wide landscaping strip
with trees, street lighting and 8-foot wide sidewalk, a 3-foot wide utility strip and 10-
foot wide landscape easement buffer as demonstrated on the plat. This
improvement will require a right-of-way dedication of approximately 16 feet. The
19~ Avenue street will be widened and improved with paving, curb and gutter,
Page - 4
landscape strip with trees and a 5-foot wide concrete sidewalk, which will include
a right-of-way dedication of 30 feet.
13.
14.
15.
16.
17.
18.
19.
A 10-foot wide landscape buffer easement is being provided for arterial buffering.
The FWCC does not require buffers on the north and south side of the
development.
The City Public Works Director or building official as allowed by Federal Way City
Code during development of the site and in conformance of Federal Way Code
Section 22-126 may require a geotechnical report which contains specific
recommendations and conclusions for the proposed development including site
preparation and grading of the site.
Water and sewer facilities are available from the Lake Haven Utility District and are
adequate to serve the proposed development according to district representatives.
It is the applicant's responsibility to secure all necessary water and sewer services
and permit approvals from the utility providers.
Surface water facilities shall be designed in accordance with KCSWDM. A storm
water detention must be dedicated to the City of Federal Way and downstream
facilities must be provided where necessary.
The applicant does not plan on providing open space pursuant to Federal Way City
Code 20-155. However, the applicant will pay a fee in lieu of providing open space
to the City pursuant to City Code 20-155.
The proposed subdivision will be served by Sherwood Forest Elementary, Illahee
Junior High and Federal Way Senior High schools. The elementary school is within
one-mile of the subject site and children of residences of the site will walk to the
school the school site. Students attending IIlahee Junior High and Federal Way
Senior High school would receive bus transportation from the site. The applicant
will pay school impact fees as controlled by City Ordinance. These fees will. be
collected at the time a resident's building permit is issued.
Gas will be furnished by Puget Sound Energy, telephone will be furnished by U. S.

Background- The preliminary plat of South Campus Bible School was submitted on
October 15, 1998, as a proposed 21-lot subdivision, with no open space tracts. The
formal "application" was determined incomplete on November 12, 1998, and complete
on December 7, 1998. Additional information was requested in a March 5, 1999, letter.
On May 25, 1999, the developer and his engineer met with city staff to review the
March 5, 1999, letter requesting additional information for the proposed subdivision. A
revised preliminary plat drawing and additional information, including a revised State
Environmental Protection Act (SEPA) checklist, were submitted on August 4, 1999
(Exhibit F).
III. CONSULTED DEPARTMENTS AND AGENCIES
The following departments, agencies, and individuals were advised of this application.
Ao
~The Community Development Review Committee (CDRC), consisting of the Federal
Way Community Development Services Planning and Building Divisions; Public
Works Engineering and Traffic Divisions; Parks & Recreation Department; Federal
Way Department of Public Safety (Police); Federal Way Fire Department; Lakehaven
Utility District; and Federal Way Public Schools. CDRC comments have been
incorporated into this report where applicable.
All property owners and occupants within 300 feet of the site were mailed a notice of
Land Use Application. The site was also posted and notice published in the newspaper
and on the city's official notice boards. No comment letters were submitted in response
to the notice of application (Exhibit G).

In accordance with SEPA and FWCC Chapter 18, Environmental Protection, all
property owners and occupants within 300 feet of the site, and all affected agencies,
were notified of the proposed action and the city's environmental determination. In
addition, the site was posted and notice placed in the newspaper and on the city's
official notice boards (Exhibit H).
IV. STATE ENVIRONMENTAL POLICY ACT
A. An Environmental Determination of Nonsignificance (DNS) was issued for the
proposed action on September 4, 1999 (Exhibit I).
This determination was based on review of information in the project file, including
the environmental checklist, resulting in the conclusion that the proposal would not
result in probable significant adverse impacts on the environment.
Bo
One comment letter was received from Mr. Robert White during the 14-day SEPA
comment period. The letter requested fencing to be installed by the applicant to
maintain privacy and expressed concern about new traffic on 353r'~ Place SW. No
changes or corrections were made to the city's initial determination (Exhibit d).
V. NATURAL ENVIRONMENT
ao
Storm Water Runoff- The applicant will be required to provide storm drainage
improvements to comply with all applicable Core and Special Requirements outlined
in the King County Surface Water Design Manual (KCSWDM), including surface
water quantity and quality control. ESM Consulting Engineers prepared and
submitted a Preliminary Technical Information Report on November 30, 1998, to
the Department of Community Development Services for review by the Public
Works Department (Exhibit K).
The preliminary plat depicts storm water collected in a detention pond at the
northeast comer of the site, with release to a downstream channel (See Exhibits A &
L). See Section IX-C (page 8) of this report for a detailed description of the proposed
drainage facilities.
Bo
Soils - The 1973 King County soils survey map lists the soils type as Alderwood
Gravelly Sandy Loam (AgB) and Arents, Alderwood material (AmB). AgB soils are
characterized as moderately well drained to poorly drained soils over a weak to
strong consolidated substratum at a depth of 24 to 40 inches. These soils are
described as capable of adequate compaction, runoff is slow, and erosion hazard is
slight with slopes at 6 to 15 percent. AmB soils are characterized as relatively level
with 0 to 6 percent slopes and moderately well drained. Runoff is slow, and the
erosion hazard is slight.
Heating Examiner Staff Report Page 3 S Campus Bible School Preliminary Plat/SUB98-0007
Co
Uo
Typical soils excavation will occur with the street construction, at the site of the
detention pond, and for utility installation. The preliminary clearing and grading plan
depicts cleating limits in compliance with city standards for street right-of-way,
surface water detention tracts, and utility easement development only.
It is anticipated that all excavated material can be used on site, and that no import fill
will be required if mass grading is approved. The July 25, 1999, Geotechnical
Report, prepared by GeoResources, contains recommendations and conclusions for
the proposed development, including site preparation and grading of the subject site.
Supplemental geotechnical analysis and recommendations may be required by the
Public Works Director or Building Official during development of the site (Exhibit
Topography - The site is slightly sloping from the southwest and southeast comers
to the center of the plat near the north property line. The plat is located within a very
shallow drainage channel of a large basin. A grading and utilities map submitted
with the application depicts the site with 0-4 percent slopes (Exhibit M & W-3).
Vegetation - The westerly one-third of the site is developed residentially and the
easterly two-thirds is used as pasture for large farm animals. The plat is subject to
the approval of a landscape plan pursuant to FWCC Section 20-158. During final
plat design and review, staffwill continue to work with the applicant to identify trees
that can be retained on the site. Retained significant trees outside of open space areas
would be regulated under FWCC Section 22-1568, Significant Trees (Exhibit N &
W-2).
Wildlife - No significant wildlife exists on the site as the site has been cleared for
residential and pasture use and is surrounded by existing single family residences.
Mapped Sensitive Areas - The Federal Way Sensitive Areas Map indicates no
geological hazardous or sensitive areas on the site (Exhibit 0).
A wetland determination was prepared by B-twelve Associates, Inc. to study the site
for potential wetlands. The study concluded there are no wetlands present on the site
(Exhibit P).
VI.
GENERAL DESIGN
Ao
Subdivision Access and Roadway System - Access to the property will be provided
by the westward extension of SW 352na Street from 19th Avenue SW. Refer to
Exhibits A & W-3, the preliminary roadway and utility plans.
SW 352na Street and 19th Avenue SW are classified by the FWCC as local streets,
providing access to residences and connecting neighborhood streets to the collector
system. Pursuant to FWCC street improvement standards, the minimum right-of-way
Hearing Examiner Staff Report Page 4 S Campus Bible School Preliminary Plat/SUB98-0007
width for local streets is 52 feet. The frontage on 21st Avenue SW must be widened,
including tapers, as approved by the Public Works Director .and improved with a
planter strip, sidewalk, and a utility easement.
Pedestrian System - Sidewalks will be provided along all lot frontages. Specifically,
street improvements include five-foot wide sidewalks on both sides of SW 352nd
Street. Half street improvements on 19th Avenue SW will include a five-foot wide
sidewalk on the west side of the street. A five-foot wide concrete sidewalk will be
provided on the east side of 21st Avenue SW. The applicant will be required to
provide an eight-foot wide paved walking path, with landscaping on each side, from
the west end of the cul-de-sac westward to 21st Avenue SW.
In addition, according to the "School Access Analysis Report" prepared by ESM, a
four-foot wide sidewalk (the city requires a five-foot wide sidewalk) will be
extended from the project site to the existing sidewalk on SW 351st Street, between
19th Avenue SW and 18th Avenue SW on the east side of 19th and on the south side
of SW 351st Street (Exhibit Q).
C. Local Streets shall have a minimum pavement section of three inches Class B
asphalt over 2 x 6 inches of crushed surfacing.
Do
Landscape Buffers and Open Space - In accordance with FWCC Chapter 20,
Subdivisions, landscaped buffers are required when the plat is adjacent to an
incompatible zoning district or merial street. The proposed plat is bordered on three
sides by single family residential zoning, therefore, no formal buffers are required on
the north, east, and south property lines. However, a ten-foot wide landscape buffer
easement is identified on the preliminary plat for merial buffering (Tract D) (Exhibit
Street tree requirements are described in section VII-A, open space requirements are
described in section VIII B, and detention tract requirements are described in section
IX C of this report.
Uo
Lot Layout - The lots range in size from 7,200 square feet to 7,900 square feet. The
proposed lots are generally rectangular. Six of the 21 lots are "flag" lots and are in
conformance with FWCC standards. (Flag lots are described as lots with 30 feet of
frontage, or less, on a public street serving as a driveway access to a larger area of
the lot where a home meeting all yard setbacks may be constructed.)
One area is designated as a "Storm Water Tract" (Tract C) and another area is
designated as street right-of-way improvements (Tract A). Both tracts will be
dedicated to the City of Federal Way.
One area is designated as "Open Space Tract" (Tract B) and another area is
designated as a "Landscape Easement" (Tract D). These two tracts are to be owned
and maintained by a Home Owners' Association (Exhibit W-I).
Hearing Examiner Staff Report Page 5 S Campus Bible School'Preliminary Plat/SUB98-0007
Fo
Existing Conditions - The site is currently developed with two single family homes,
accessory buildings, and pasture for farm animals. The single family homes and
accessory buildings will be removed at the time the Plat is developed. Single family
homes on platted lots exist to the north, east, and south. West Pointe Apartments
exist to the west across 21st Avenue SW (Exhibit R).
These conditions and comments are based on the plans submitted for preliminary plat
review and are not intended to be or constitute a detailed review of the engineering
drawings. The detailed engineering review will occur following preliminary plat
approval.
VII.
TRANSPORTATION
to
Street Improvements - In accordance with the FWCC, all street improvements must
be dedicated as city right-of-way and improved. Specifically, full street
improvements are required for SW 352n°Street and will include: 28 feet of
pavement, vertical curbs, gutters, sidewalks, street lights, and street trees within a
50-foot right-of-way width as shown on the plat.
The 21st Avenue SW arterial street is to be widened and improved (including tapers)
with paving, a six-foot wide landscaping strip with trees, street lighting, an eight-
foot wide sidewalk, a three-foot wide utility strip, and a ten-foot wide landscape
easement buffer as shown on the plat. This will require a right-of-way dedication of
approximately 16 feet.
The 19th Avenue SW local street is to be widened and improved with paving, curb
and gutter, landscape strip with trees, and a five-foot wide concrete sidewalk. This
will require a right-of-way dedication of 30 feet (Exhibit W-l).
Heath & Associates, Inc., prepared a June 17, 1999, "Left Turn Warrants Study" at
the request of the city's Assistant Traffic Engineer. In an August 24, 1999,
memorandum, the Assistant Traffic Engineer stated that off-site left-turn
improvements to 21st Avenue SW were not warranted (Exhibits S-1 & 2).
Bo
Adequacy of Arterial Roads - This proposal has been reviewed under SEPA. Based
on the FWCC, the additional traffic to be generated by this development does not
require any major roadway improvements for vehicles or pro rata share payments,
according to the city's Assistant Traffic Engineer.
Vlll.
PUBLIC SERVICES
A. Schools - As part of the city's review of the proposal, the preliminary plat
application was referred to the Federal Way School District for comments.
Hearing Examiner Staff Report Page 6 S Campus Bible School Preliminary Plat/SUB98-0007
Bo
Comments received from the School District on November 4, 1998, and November
13, 1998, included the following information:
The proposed subdivision will be served by Sherwood Forest Elementary, Illahee
Junior High, and Federal Way Senior High schools. As the elementary school is
within one mile of the subject site, students would walk to school from the site.
Students attending Illahee Junior High ~tnd Federal Way High schools would
receive school bus transportation from the site. The current bus stop that would
serve Illahee Junior High students is located at 19th Avenue SW at 35228. The bus
stop for Federal Way High School students is located at 19th Avenue SW and SW
353rd. School service areas are reviewed annually and may be adjusted to
accommodate enrollment growth and new development.
The existing route of travel from the proposed subdivision to Sherwood Forest
Elementary School is via a roadway with gravel shoulders and ditches. FWCC
Section 20-156(a) requires the applicant to install an improved pedestrian corridor
and sidewalk from the subject site to Sherwood Forest Elementary School along
the eastern side of 19th Avenue SW and south side of SW 351st Street, providing a
safe route of travel for school age children. The sidewalks are to be a raised, five-
foot wide concrete sidewalks located in the easterly portion of 19th Avenue SW
and the southerly portion of SW 351 st Street. Refer to condition #5 of the
preliminary plat approval (page 14). The new sidewalk is to provide safe student
pedestrian access along 19th Avenue SW and SW 351st Street for elementary
school students (Exhibit Q).
School impact fees, as authorized by city ordinance, will be collected at the time of
the residence building permit issuance. School impact fees are determined based on
the school district's Capital Facilities Plan and are subject to annual adjustment.
Open Space - According to the City of Federal Way Facilities Map, the nearest city
park is Saghale located next to Saghale Junior High School on SW Campus Drive
approximately one mile north of the plat site. Other public parks in the vicinity
include Panther Lake, Lakota, Dumas Bay, and West Hylebos Wetlands State Park
(Exhibit T).
To provide adequate recreational opportunities commensurate with new residential
development, FWCC Chapter 20, Subdivisions, requires set-aside of land on site for
open space, or a fee-in-lieu-payment for the open space. Specifically, FWCC Section
20-155(b) requires all residential subdivisions to provide open space in the amount
of 15 percent of the gross land area of the subdivision site; or pay a fee-in-lieu of
payment for all or portions of the open space area required.
Total open space required for this plat is 31,298 square feet (15 percent of the
208,652 square foot parcel). Pursuant to FWCC Section 20-155, the applicant
proposes to not provide the required open space, but rather make an open space fee
payment. The fee would be based on the assessed value of the land according to the
Hearing Examiner Staff Report Page 7 S Campus Bible School Preliminary Plat/SUB98-0007
King County Assessors Office valuation of the subject site at the time the final plat
is reviewed.
The city's Parks and Recreation Department staff has reviewed the proposed fee-in-
lieu of open space requirement for the preliminary plat and supports the applicant's
proposal., This fee must be paid to the city before the final plat is approved.
The applicant proposes to provide no open space for the plat. The open space
obligation will be provided through fee-in-lieu of open space, due prior to final plat
approval per FWCC Section 20-155.
Co
Fire Protection - The Certificate of Water Availability from the Lakehaven Utility
District indicates that water will be available to the site in sufficient quantity to
satisfy fire flow standards for the proposed development. The Federal Way Fire
Department requires that a fire hydrant be located within 350 feet of each lot. The
preliminary grading and utility plan does not depict the location of fire hydrants
within the plat. The Federal Way Fire Department must approve the location of these
hydrants.
IX. UTILITIES
to
Sewage Disposal- The applicant proposes to serve the proposed plat by a public
sewer system managed by the Lakehaven Utility District. A July 2, 1998, Certificate
of Sewer Availability indicates the district's capacity to serve the proposed
development through a Developer Extension Agreement (DEA) between the
applicant and the district. According to the preliminary plat, an extension of the
existing sanitary sewer main west of 21 st Avenue SW will serve the site. The
applicant will need to renew the expired DEA and certificate before the engineering
approval is granted (Exhibit U-1 to 3),
Water Supply - The applicant proposes to serve the subdivision with a public water
and distribution system managed by the Lakehaven Utility District. A July 2, 1998,
Certificate of Water Availability indicates district's capacity to serve the proposed
development through a DEA. The applicant must renew the expired DEA before the
engineering approval is granted (Exhibit V-1 to 3).
Drainage Facilities - The site is located in the South Lower Puget Sound Sub-Basin,
in an area identified by the Executive Proposed Basin Plan: West Branch Hylebos
Creek Sub-Basin, as having downstream conveyance, flooding, erosion, and habitat
problems associated with stormwater runoff. The applicant is proposing to provide
mitigation as recommended in the Basin Plan specifically, Recommendation #BW-2
which calls for the use of a seven-day storm event in sizing on-site detention
facilities. Surface water runoff will be controlled by a system of curbs, berms,
drainage swales, and/or catch-basins, conveyed to the detention pond, and then to an
appropriate discharge point.
Hearing Examiner Staff Report Page 8 S Campus Bible School Preliminary Plat/SUB98-0007
A Level I Downstream Analysis, including onsite basin comparisons, offsite
conveyance capacity checks, and core and special requirements under the 1992
KCSWDM is required by the Public Works Department.
The applicant is required to construct improvements necessary to mitigate all
identified conveyance problems, whether existing or resulting from the plat's
development, as identified during engineering plan review. Engineering approval
will not be granted if it is determined that the applicant's proposed mitigation is not
adequate to address the impacts of the project.
Storm drainage facilities are to be designed in accordance with all applicable core
and special requirements outlined in the KCSWDM, and per the basin complex
variance request approval. A detention pond and biofiltmtion swale are proposed to
provide runoff control for the site. The approved storm drainage facilities must be
constructed per city code requirements, prior to final plat approval and recording of
the subdivision condition. The detention facilities shall be screened with vegetation
from the plat and surrounding properties. Refer to recommended approval condition
nmbers 1, 2, and 3 of the preliminary plat.
X. ANALYSIS OF DECISIONAL CRITERIA
The FWCC establishes review procedures and decisional criteria for deciding upon
various types of land use applications. Pursuant to FWCC Chapter 20, Subdivisions,
Section 20-110, preliminary plat applications are submitted to the heating examiner for
public hearing. The preliminary plat application and the recommendation of the hearing
examiner are submitted to the city council for approval or disapproval.

FINDINGS OF FACT
Based on an analysis of the proposed action, the environmental record, and related
decisional criteria, the Department of Community Development Services finds that:
The proposed action is to subdivide a partially developed 4.79 acre parcel into 21
single family lots of 7200 square feet, or greater. Existing land uses on three sides of
the site are single family residences on platted lots. An apartment complex is located
across 21 st Avenue SW to the west of the site.
2. All existing structures on the site are to be removed before approval of the final plat.
o
Zoning for the site and adjacent lots to the north, east, and south is RS-7.2. The
apartments to the west across 21st Avenue SW are zoned RM-1800. The proposed
residential subdivision density is consistent with existing adjacent land uses and
zoning.
o
An Environmental Determination ofNonsignificance (DNS) was issued for this
proposed action by the city's ResponSible Official on September 4, 1999. One letter
was submitted before the comment deadline date.
No appeals were received and the SEPA determination has not been modified as of
the date of this report. This environmental determination is incorporated by reference
as though set forth in full.
o
Water and sewer facilities are available from the Lakehaven Utility District and are
adequate to serve the proposed development, according to district representatives.
The expired certificates must be renewed. It is the applicant's responsibility to
secure all necessary water and sewer services and permit approvals from the utility
provider.
Surface water facilities will be designed in accordance with the KCSWDM. A
stormwater detention tract must be dedicated to-the City of Federal Way and down
stream facilities must be provided where necessary.

Federal Way Comprehensive Plan - Land Use
Goal
LUG 1 Improve the appearance and function of the
built environment.
Policies
LUP1
Develop residential design performance stan-
dards to maintain neighborhood character and
ensure compatibility with surrounding uses.
LUP2
Use design and performance standards to
achieve a greater range of housing options in
multiple family designations.
LUP3
Support the establishment of design and per-
formance standards to create attractive and
desirable commercial and office developments.
2.6 DEVELOPMENT REVIEW
PROCESS
The Land Use chapter provides the policy foundation
for implementing zoning and development regula-
tions. In developing policy concerning future land use
regulations, or revisions to existing regulations, every
effort was made to instill certainty and efficiency in
the development process. Recent State legislation has
focused on developing streamlined and timely permit
processing. Prior to this legislation, the City con-
ducted Developer Forums to solicit input regarding
the City's permit processing system. Comments
received during the Forums provided invaluable infor-
mation to evaluate the City's permit system. Through
the following policies, the City continues to strive to
provide an efficient and timely review system.
Goal
LUG2
Develop an efficient and timely development
review process based on a public/private
partnership.
Policies
LUP4 Maximize efficiency of the development
review process.
LUP5
Assist developers with proposals by contin-
uing to offer preapplication meetings in order
to produce projects that will be reviewed
efficiently.
LUP6
Conduct regular reviews of development reg-
ulations to determine how to improve upon
the permit review process.
LUP7
Integrate and coordinate construction of
public infrastructure with private development
to minimize costs wherever possible.
LUP8
Increase efficiency in the permit process by
responding to State legislation concerning
development review processes.
2.7 ClTYWlDE POLICIES
Citywide policies apply to all Comprehensive Plan
designations. These general policies are intended to
maintain the quality of the living and working
environment and ensure that the interests, economy,
and welfare of the community are considered.
Policies
LUP9
Designate and zone land to provide for
Federal Way's share of regionally-adopted
demand forecasts for residential, commercial,
and industrial uses for the next 20 years.
LUPI0
Support a diverse community comprised of
neighborhoods which provide a range of
housing options; a vibrant City Center; well
designed and functioning commercial areas;
and distinctive neighborhood retail areas.

LUP13
Support the continuation of a strong residen-
tial community.
Evaluate household and employment forecasts
on a periodic basis to ensure that land use
policies based on previous assumptions are
current.
Distribute park and recreational opportunities
equitably throughout the City.
2.8 LAND USE DESIGNATIONS
The land use designations in the Comprehensive Plan
recognize the relationships between broad patterns of
land uses. The designations set forth locational criteria
for each specific class of uses consistent with the long
term objectives of the Plan. These designations pro-
vide the purpose and intent for specific zoning dis-
tricts. The location of comprehensive plan land use
designations are shown on the Comprehensive Plan
Designations Map (Map 11-2).
Residential Areas
Single Family
Federal Way is known for its quality single family
neighborhoods. This section contains goals and
policies that will shape future development and pro-
tect or improve the character and iivability of
established neighborhoods.
The demand for and development of single family
housing is expected to continue for the foreseeable
future. Single family development will occur as in-fill
development of vacant lots scattered throughout
existing neighborhoods and as subdivisions on vacant
tracts of land. To address future housing needs, the
Land Use chapter encourages new techniques for
developing single family subdivisions. Such tech-
niques include clustering, planned unit developments,
lot size averaging, and zero lot line development. New
to single family neighborhoods is the introduction of
accessory dwelling units and special needs housing as
required by State law and City ordinance. Further-
more, future residential code revisions will address the
compatibility and design of in-fill development and
special needs housing.
Single Family Low Density
The Single Family Low Density designation retains
larger urban lots in order to avoid development pres-
sure on or near environmentally sensitive areas and to
retain areas that have unique area-wide circumstance.
There are two notable locations: Spring Valley,
located in the southern portion of the City; and along
Puget Sound near Dumas Bay in the vicinity of Camp
Kilworth and the Palisades Retreat property.
The Single Family Low Density designation continues
the historic application of low density zoning in areas
that lack urban services and infrastructure. Moreover,
the application of large urban lot zoning is appropriate
to avoid excessive development pressures on or near
environmentally sensitive areas as well as to serve as a
buffer between adjacent land use designations of
higher densities.
The Single Family Low Density designation in the
Spring Valley and Dumas Bay areas have numerous
environmentally sensitive features including, but not
limited to: wetlands, flooding potential, geologically
hazardous areas, streams (including salmonid habitat),
and wildlife habitat, and groundwater infiltration
potential. Due to the sensitive nature of this area, the
Draft Hylebos Creek and Lower Puget Sound Plan
recommends zoning of one lot per five acres.
Single Family Medium Density
The Single Family Medium Density designation
creates urban lots with a density range of one to three
dwelling units per acre to avoid developing on or near
environmentally sensitive areas. The Single Family
Medium Density designation can be found along the
Puget Sound shoreline and south of South 356th
Street, both east and west of SR 99. Lot sizes of
35,000 and 15,000 square feet provide for a transition
in density between ian~l.~s~gn_a_ted as Single Family
and designated
ltigh
Revised December 1998 I1-13
Federal Way Comprehensive Plan - Land Use
areas designated as Single Family Medium still lack
urban services and infrastructure.
The relatively large lot sizes along the Puget Sound
shoreline areas are appropriate due to geological
features including steep slopes and landslide hazards
commonly associated with marine bluffs. As with the
Single Family Low designation, the Single Family
Medium designations south of South 356th is located
in the West Branch Hylebos Creek Sub-Basin. As
noted in the Single Family Low Density description,
this sub-basin contains a number of environmentally
sensitive areas.
Single Family High Density
A majority of the single family residential land in the
City is designated as Single Family High Density.
Urban densities of and 8.7 dwelling units per acre in
the RS 9.6, RS 7.2, and RS 5.0 zoning districts respec-
tively, provide for a range of housing densities. Single
Family High Density residential designations are
located within close and convenient proximity to
neighborhood business centers, areas of existing or
future employment, transit, and existing urban infra-
structure and services. Future Single Family High
Density development should provide good access to
collector and arterial streets.
Goal
1¢~ LUG3 Preserve and protect Federal Way's single
family neighborhoods.
LUG3.1 Provide wide range of housing densities and
types in the single family designated areas.
Policies
LUPI4
Maintain and protect the character of exist-
ing and future single family neighborhoods
through strict enforcement of the City's land
use regulations.
LUPI5 Protect residential areas from impacts of
adjacent non-residential uses.
LUPI6
~LUPI7
LUPI8
LUP19
LUP20
Revise existing land use regulations to pro-
vide for innovation and flexibility in tile
design of new single family developments
and in-fill.
Encourage the development of transporta-
tion routes and facilities to serve single
family neighborhoods. Special attention
should be given to pedestrian circulation.
Encourage the development of parks and the
dedication of open space in and adjacent to
residential areas to preserve the natural
setting of Federal Way.
Consider special development techniques
(e.g., accessory dwelling units, zero lot
lines, lot size averaging, and planned unit
developments) in single family areas, pro-
vided they result in residential development
consistent with the quality and character of
existing neighborhoods.
Preserve site characteristics that enhance
residential development (trees, water-
courses, vistas, and similar features) using
site planning techniques such as clustering,
planned unit developments, and lot size
averaging.
Multiple Family
The multiple family residential land use designation
represents an opportunity, to provide a range of
housing types to accommodate anticipated residential
growth. Increasing population, the decline in average
family size, and increasing cost of single family
homes have created heavy demand for new housing
types. The Land Use chapter encourages the develop-
ment of new housing types, such as duplexes, town-
houses, and condominiums in existing multiple family
areas and within mixed-use development in com-
mercial areas.

Federal Way WA 98023
RE: South Campus Bible Subdivision
Marion Hess
City of Federal Way
33530 First Way South
Federal Way WA 98003
Dear Marion Hess,
This is a comment to the South Campus Bible Subdivision that is to be located on the 35200
block of 21't Avenue SW, between 19t~ and 21't Avenues SW.
We live on 353rd PL SW on lot #0900, which will have our backyard facing into the
backyard of lot #10 and #11 of the new subdivision. We currently have no fence, which
allows us to view the horses and trees behind us. We couldn't tolerate looking into another
families backyard so we're requesting a fence at least 6 ft tall is built to maintain the illusion
of privacy we now enjoy.
We're also concerned about the new traffic that will be coming down the street in front of
our house on 353'd PL SW. There are many children who live on this street and there are
school bus stops for the Jr. High and High School children. With no outlet to 21~ Avenue
SW from the new subdivision more people will be using this street to get to 21'~ Avenue
SW. The new Park and Ride on 21't being built will also generate more traffic on our street
as people seek to avoid the traffic light(s) on 35¢ Avenue SW. We're afraid our street will
be used as an arterial road if traffic or speed controls are not placed on our street. Please
consider speed bumps or signage to prevent this new traffic from impacting our lives here or
worse, causing an accident with one of the many children walking home from their bus
stops or from the elementary school.
Sincerely,
Robert White

SECTION I
PROJECT OVERVIEW
The proposed project South Campus Bible School Subdivision, is located east of 21s'
Ave. SW, north of SW 353rd Place and west of 1¢h Avenue SW (see vicinity map Figure
l-A), containing approximately 4.78 acres. The north side of the site abuts an older
residential subdivision, the south and east sides abuts residential subdivisions, and the
west side abuts 21~' Ave SW and an apartment complex.
The majority of the site is under 6% slopes.
The site has two single family residences with several outbuildings surrounded by pasture
lands with mature trees mostly around the perimeter. The existing on-site buildings will
be demolished.
This site is in the WH~ 15 drainage basin of the Panther Lake Drainage Basins (See
Surface Water Management Plan, Phase I). Although this site is- within the Panther Lake
Regional detention facility it is to far away to utilize it. So the project will provide an on-
site detention facility using the BW-2 West Branch Hylebos Basin detention
'requirements. The site will provide water quality treatment within the detention pond.
The only off-site flows coming onto the site are from the rear yards of the abutting
subdivision to the south. The road and houses flow east along SW 353ra St. and then 18th
Ave. SW to a detention facility east of this site.

Review of 7 Core Requirements and 12 Special Requirements of 1990 KCSWDM
We have reviewed the Core and Special Requirements in Chapter No. I of the
King County Surface Water Design Manual (KCSWDM), and offer the follo~ving
comments:
Core Requirement No. 1 - Discharge at the Natural Location
Currently the majority of the site drains to the center and northerly portion
of the site. From this point flow continue north in a large topographical
low area.
The proposed project will continue to discharge small volumes at this
north-center section of the site. The impervious areas will be conveyed to
an on-site detention facility. From this facility flow will discharge into a
bio-filtration swale and than discharge into a new conveyance line that
will connect to the existing conveyance system in SW 351s~ Street.
Core Requirement No. 2 - Offsite Analysis
An offsite analysis is required for this site because more than 5,000 square
feet of impervious area is being proposed. Please refer to the Level One
Drainage Analysis in this report for a more descriptive narrative of the
downstream conditions.
Core Requirement No. 3 - Runoff Control
The proposed desig'n contains more than 5,000 square feet of impervious
area that is subject to vehicular use; therefore, on-site biofiltration is
required. An on-site facility shall be designed to conform to the 1990
King County Surface Water Design Manual, Hylebos Creek and Lower
Puget Sound Basin Plan and the City of Federal Way worksheet.
Core Requirement No. 4 - Conveyance System
As part of the final engineering design for this project, it will be required
to demonstrate that the runoff from the 100-year/24-hour storm can be
conveyed downstream per Core Requirement No. 2.
Core Requirement No. 5 (Erosion ! Sedimentation Control), No. 6
~Maintenance and Operation), and No. 7 (Bonds and Liability)
Will apply during the final design reviexv.
EXHIBIT. ,K
PAGE & OF
Special Requirement No. 1 - Critical Drainage Area
This project does lie ~vithin the West Branch of the Hylebos Creek and
Lower Puget Sound Basin Plan. This project shall conform with the
recommendations of this plan and the City of Federal Way's
recommendations.
Special Requirement No. 2 -Compliance with an Existing Master
Drainage Plan
Does not apply.
Special Requirement No. 3 - Conditions Requiring a Master Drainage
Plan
Does not apply.
Special Requirement No. 4 - Adopted Basin or Community Plans
The project does lie within the. Hylebos Creek and Lower Puget Sound
Basin Plan. This project shall conform with the recommendations of this
plan and the City of Federal Way's recommendations.
Special Requirement No. 5 - Special Water Quality Controls
The site will collect runoff from less than one acre of impervious surface
that will be subject to vehicular use, therefore no wet pond, wet vault or
water quality swale will be required.
Special Requirement No. 6 - Coalescing Plate/Oil Water Separators
The site has less than 5 acres which is subject to vehicular use therefore
this requirement does not apply.
Special Requirement No. 7 - Closed Depression
Does not apply.
Special Requirement No. 8 - Use of Lakes, Wetlands, or Closed
Depressions for Peak Runoff Control
Does not apply.
EXHIBIT, K ,
PAGE_ ? OF
Special Requirement No. 9 - Delineation of 100-Year Floodplain
The 100-year floodplain does not enter this site.
Special Requirement No. 10 - Flood Protection Facilities for Type 1
and 2 Streams
Does not apply.
Special Requirement No. 11 - Geotechnical Analysis and Report
A geotechnical review of the site will be required in the design phase.
Special Requirement No. 12 - Soils Analysis and Report
A Soils Analysis and Report will be part of the overall submittal to the
City of Federal Way.
Summary
The storm water runoff will be collected from the buildings, streets and
landsdaped areas, and conveyed through a pipe system to a detention facility than
onto a storm water bio-filtration swale. This site will have a detention facility
utilizing the Hylebos Creek and Lower Puget Sound "BW-2" recommendations.
The soils are the Alderwood,'Arents/Alderwood Series which are very poor soils
for infiltration. Infiltration pits will need to be dug during the design stage of the
project to see if infiltration can be done.
The standards to be followed are per the 1990 King County Surface Water
Management Design Manual, along with recommendations by the City of Federal
Way.

OFF-SITE ANALYSIS
This project is xvithin the Hylebos Creek and Lower Puget Sound adopted basin plan.
The following is a Preliminary Level I Downstream Analysis. It will look at the drainage
system ¼ mile downstream.(See Overall Drainage Map in Appendix)
The majority of the site drains to a main low area in the north / center section of the site.
From this point flows continues north overland to SW 351" St. where it is picked up in
the street's conveyance system. Flows continue north in a 12" diameter conveyance
system to SW 350~h St. and on to a open ditch behind the Northwest Church. This open
ditch continues to a newly enlarged detention facility (1995) on the north side of the new
parking lot for the Northwest Church.
From this detention facility, flows continue north in a 12" diameter conveyance system
under SW 348~ Street to another detention facility between SW 348~h Street and 34Th
Street. This is the approximate ¼ mile downstream drainage system from the boundary
of the S. Campus Bible School Site.
Per the Comprehensive Surface Water Management Plan, Phase I, Chapter 6, Panther
Lake, there are no existing problem areas within the 1/4 mile downstream path.
See overall Drainage Map enclosed in this report.

SECTION IV
RETENTION / DETENTION ANALYSIS AND DESIGN
This project will provide a onsite detention system since the Panther Lake Regional
Stormwater Detention Facility is to far away to utilize.
This section will look at existing and developed flows from this site The developed
conditions will incorporate the future conditions of the project site.
This project lies within one drainage basin. (See Overall Drainage Map in Appendix) The
requirements of the BW-2 - 7 day storm events will be used
The following parameters were Used in the development of the existing and developed
flows:
* Methodology / Precipitation:
KCSWDM 7-day (KC7) Hydrograph,Methodology
7 day Precipitation 2 year = 4.2 inches, 10 year = 5.8 inches, 100 year -- 10.1
inches
* Basin Size:
Site is about 4.78 acres. The drainage basin size is about 4.6 acres. See the
enclosed "On-Site Drainage Plan".
* CN
The curve number (CN) comes from the soil type and land use. The soils around
this site and surrounding land are mostly Alderwood gravelly sandy loam soils.
These soils for the most part are moderately well drained soils that have a weakly
consolidated to strongly consolidated substratum at a depth of 24 to 40 inches.
Existing Conditions:
The majority of this site is covered with pasture lands with perimeter trees. So
using a land use description of" Meadow or pasture land" and a soil group of"C"
(Alderwood), the CN for existing conditions will be "85".
Future Conditions:
There will be two CN numbers for the developed conditions. The grassed or
landscape areas in.good condition will have a CN of 86. The second is impervious
areas with a CN of 98 (This analysis uses about 0.66 acres of asphalt / sidewalks
and 2,000 s.f. of impervious surface per lot (21 x 2,000 = 42,000 s.f.), for a total
of 1.6 acres).
EXHIBIT
PAGE t"a OF, :;r
Time of Concentration (Tc) Existing:
Existing basin Tc will start at the Southeast comer of the project and continue to
the northwesterly comer of the site. The first 300' drops 6', for a slope of 2.0 %.
The next 150' drops 4' for a slope of 2.7 %.
Proposed:
The developed site's Tc will still start at the southeast comer and continue to the '
northwesterly comer of the site. The first 180' will still flow overland on grass on
about a 2% slope. It will continue 350' on the new road or in a conveyance system
to the detention pond dropping about 10', for a slope of 2.9 %.

INTRODUCTION AND SCOPE
This report summarizes the results of our geotechnical engineering services for
the proposed South Campus Bible School residential development. The site is located
between 19th and 21st Avenues Southwest and will be accessed by proposed S.W. 352
Street Court from the east. The location and the proposed layout of the site are shown on
the Site PlanNicinity Map, Figure 1.
Our understanding of the project is based on our discussions with you, our
review of the preliminary plat map and grading plans provided, and our site visits. We
understand that the site consists of approximately 4.78 acres to be developed as
approximately 21 single-family residential lots with associated roadways and utilities. A
detention pond is proposed in the north central portion of the site. We also understand
that grading at the site will be minimal to reach design grades. We further understand
that the plat will be served by local water and sewer utility districts.
The purpose of our services is to evaluate the surface and subsurface
conditions at the site as a basis for satisfying the requirements for the City of Federal
Way Sensitive Area Ordinance and provide geotechnical recommendations and design
criteria for the project. GeoResources provided geotechnical and hydrogeologic services
for the project. Engineering recommendations and design criteria were provided by
ADAPT Engineering, Inc. Specifically, our scope of services for this project will include
the following:
1. Review the available geologic, hydrogeologic and geotechnical data for the site
area.
2. Conduct a geologic reconnaissance of the site area.
3. Explore the shallow subsurface conditions at the site by monitoring the
excavation of backhoe test pits.
4. Evaluate the erosion hazards at the site per the City of Federal Way ordinance.
5. Provide geotechnical recommendations for site grading including site
preparation, subgrade preparation, fill placement criteria (including hillside
grading), suitability of on-site soils for use as structural fill, temporary and
permanent cut and fill slopes, drainage and erosion control measures.
6. Provide recommendations and design criteria for foundation and floor slab
support, including allowable bearing capacity, subgrade modulus, lateral
resistance values and estimates of settlement.

SITE CONDITIONS
SURFACE CONDITIONS
The proposed South Bible School residential development site is located in the
west-central portion of the Federal Way upland area. The site is bounded by established
residential development. The site is generally pastureland with scattered trees along the
margins and in the northeast comer.
Existing residential structures and out buildings are located in the west portion of
the site. This includes a horse barn and coral area. It should be noted that this area
likely has several feet of bedding (organic) matedal within and near the building.
Several unimproved roads and trails traverse portions of the site randomly. The
location layout of the site is shown on the Site PlanNicinity Map, Figure 1.
The ground surface at the site is generally fiat to gently sloping. Elevations in the
site area range from approximately 390 feet in the southeast to about 376 feet in the
north central portion of the site. Site topography is shown on the Site.PlanNicinity Map,
Figure 1.
In general, we observed no evidence of soil movement or slope instability in the
site area at the time of our site visit. No evidence of significant erosion was observed at
the site.
The majodty of the site is vegetated with pasture grass with scattered brush and
conifer and deciduous trees. The northeast portion of the site is lightly forested with
mixed evergreen and deciduous trees with a heavy grass and brush understory.
No evidence of surface water flow was observed in the site area at the time of our
reconnaissance. The general topography of the site area indicates that most of the site
drains towards the north and west.
SITE GEOLOGY
The site is generally situated within the Federal Way glacial upland area. The near
surface soils at the site generally consist of Vashon glacial till and advance outwash
material. These soils and the existing topography are the result of the most recent
Vashon stade of the Fraser glaciation that occurred between about 12,000 and 15,000
years ago, and weathering and erosion that has occurred since that time. A description
of the surficial soils is included in the "Site Soils" section of this report.
In general, Vashon glacial till underlies this upland site and adjacent areas. Based
on the results of our subsurface explorations, the glacial till thins in the northwest portion
of the site. The till is underlain by a sand and gravel glacial outwash material. Based on
our experience in the area, glacially consolidated advance outwash underlies the site at
a relatively shallow depth, 10 to several 10's of feet, and older glacial and interglacial
soils at depth.
Glacial till generally consists of silty sand with vadable gravel, cobbles and
boulders that was deposited at the base of the advancing glacial ice. The till is
commonly refereed to as hardpan and is in a dense to very dense condition where
undisturbed. Although glacial til! provides excellent foundation support, it has a relatively
Iow permeability and is not typically suitable for infiltration of stormwater.

Page 3
The underlying advance glacial outwash encountered at the site consists of dense
to very dense sand and gravel with cobbles, occasional boulders and variable silt
content.
SITE SOILS
The SCS (King County Soil Conservation Survey) has mapped the site soils as
Alderwood gravelly sandy loam (AgB). The Alderwood soils typically form in glacial till
areas and are described as having a moderate permeability with little to no erosion
hazard.
We observed no active erosion in the site area during our reconnaissance. Based
on our observations, the site soils appear to have a Iow susceptibility to erosion,
particularly where vegetation is established.
SUBSURFACE EXPLORATIONS
Subsurface conditions at the sites were evaluated by excavating 10 test pits with a
rubber-tired backhoe. The test pits extended to depths ranging from about 4.5 to 10.5 feet
below existing site grades. The test pits were located in the field by our representative by
pacing from existing site features such as property comers. The approximate locations of
the test pits are indicated on the attached Site Plan/Vicinity Map, Figure. 1.
Our representative continuously monitored the excavation of the test pits, maintained
logs of the subsurface conditions, and obtained representative samples, as needed. The
soils encountered were visually classified in accordance with the system described in
Figure 2, ASTM D-2488. The logs of the test pits are included as Figures 3 through 6.
SUBSURFACE CONDITIONS
The subsurface conditions at the site were evaluated by excavating 10 backhoe
test pits and by observing the soils exposed in the adjacent areas. In addition, we
reviewed the available geologic and geotechnical data for general area.
In general, undisturbed dense glacial till or hardpan was encountered in the test
pits located over most of the site. The till was encountered at shallow depths, between
1.5 and 2.5 feet. The till was ovedain by a veneer of weathered till and remnant
recessional outwash (?) to depths of up to 5.0 feet. The undisturbed glacial till was in a
dense to very dense condition. The overlying weathered soils were in a medium dense
to dense condition, except near the ground surface where they were in a loose condition.
Test pit 8, located in the northeast portion of the site, encountered advance
outwash sand and gravel with variable silt, cobble and boulder content to the full depth
explored, 10.5 feet. The glacial till appears to be very thin or absent in the northeast
portion of the site. The till encountered in Test Pit 9, located near the proposed location
of the storm pond, extended to a depth of approximately 7.5 feet.
No ground water seepage was observed in our test pit excavations at the site.
Based on the nature of the near surface soils, remnant outwash material and weathered
till over undisturbed till in most of the site area, seasonally perched ground water
conditions should be expected during and following periods of extended wet weather.
As previously discussed, several feet of organic dch material was observed near
the horse barn and coral area located in the west portion of the site. This matedal was
in a wet condition. Based on our discussions with the existing tenant and neighbors, this
portion of the site and the Iow area in the north central portion of the site commonly have
ponded water during wet weather conditions. We expect that soils in these areas will be
above the optimum moisture content except following an extended period of dry

CONCLUSIONS AND RECOMMENDATIONS
GENERAL
Based on the results of our subsurface exploration program, it is our opinion that
the site is suitable for the proposed residential development. The ground surface at the
site is fiat to gently sloping and there is little to no erosion hazard based on the SCS
data. Proposed grading at the site is minimal and proper erosion/sediment control
measures will reduce or eliminate any erosion dsk in the exposed or disturbed areas.
In general, the native sand and gravel soils observed in the northeast portion of the
site are suitable for use as structural fill material. Matedal with less than 5 percent fines
should be considered equivalent to select borrow material.
The silty soils that occur over most of the site are moisture-sensitive and
susceptible to disturbance when wet. Perched ground water conditions may be
associated with these soils during or following extended pedods of precipitation. To
reduce grading and construction costs, we recommend that earthwork be undertaken
during dry weather conditions.
Pertinent conclusions and geotechnical recommendations regarding the design and
construction of the proposed development are presented below.
LANDSLIDE HAZARD AREAS
Classification
The City of Federal Way Critical Areas Ordinance, defines a landslide hazard area
as 1) one containing slopes equal to or greater than 40 percent with more than a 20-feet
vertical relief, and 2) one containing soils described by the Soil Conservation Service
(SCS) Soil Survey as having a "severe" limitation for building site development due to
slope.
The ground surface at the site are fiat to gently sloping, less than 10 percent. No
groundwater seepage was encountered in the test pits at the site. Since no slopes of 40
percent or greater or groundwater seepage were observed at the site, the site does not
meet the technical cdteda of a landslide hazard area.
LIQUEFACTION
Based on our review of the subsurface conditions, we conclude that the site soils are
not susceptible to liquefaction. The near-surface soils are generally in a dense condition
and the static water table is located well below the site. Shaking of the already dense soil
is not apt to produce a denser configuration and subsequently excess pore water
pressures are not likely to be produced.
EROSION AND SEDIMENTATION CONTROL
Erosion hazard areas are defined by the City of Federal Way as "those areas that
are classified as having moderate to severe, severe or very severe erosion potential by
the Soil Conservation Service, United States Department of Agriculture (USDA)." The
subject property is located in an area mapped by the Soil Conservation Service as
Alderwood gravely sandy loam (AgB). The erosion hazard for these soils ranges from
little to none.
It is our opinion that the potential erosion hazard of the site is not a limiting factor
for the proposed development. Removal of natural vegetation should be minimized and
limited to the active construction areas. Temporary and permanent erosion control
measures should be installed and maintained dudng construction or as soon as practical
thereafter to limit the additional influx of water to exposed areas and protect potential _

receiving waters. Erosion control measures should include, but not be limited to, berms
and swales with check dams to channel surface water runoff, ground cover/protection in
exposed areas and silt fences. Graded areas should be shaped to avoid concentrations
of runoff onto cut or fill areas, slopes or other erosion-sensitive areas. Temporary
ground covedprotection such as jute matting, excelsior matting, wood chips or clear
plastic sheeting should be used until permanent erosion protection is established.
EARTHWORK
Site Preparation
All areas to be graded/excavated should be cleared of deleterious matter including
any existing structures, foundations, abandoned utility lines, debds and vegetation.
Graded areas should be stripped of any forest duff and organic-laden soils. '
Based on our explorations, we estimate that stripping on the order of 3 or 6 inches
will be necessary to remove the root zone and surficial soils containing organics. Areas
with deeper, unsuitable organics should be expected in the vicinity of the home barns,
local depressions or heavy vegetation. Stripping depths of up to 2 feet or more may
occur these areas. These materials may be stockpiled and later used for erosion control
and landscaping/revegetation. Materials that cannot be used for landscaping or erosion
control should be removed from the project site.
Where placement of fill matedal is required, the exposed subgrade areas should be
compacted to a firm and unyielding surface prior to placement of any fill. We
recommend that trees be removed by overturning in fill areas so that a majodty of the
roots are removed. Excavations for tree stump removal should be backfilled with
structural fill compacted to the densities described in the "Structural Fill" section of this
report.
We recommend that a member of our staff evaluate the exposed subgrade
conditions after removal of vegetation and topsoil stripping is completed and pdor to
placement of structural fill. The exposed subgrade soil should be proofrolled with heavy
rubber-tired equipment dudng dry weather or probed with a 1/2-inch-diameter steel rod
during wet weather conditions.
Any soft, loose or otherwise unsuitable areas delineated during proofrolling or
probing should be recompacted, if practical, or overexcavated and replaced with
structural fill, based on the recommendations of our site representative.
Structural Fill
All fill material/trench backfill should be placed as structural fill. The structural fill
should be placed in horizontal lifts of appropriate thickness to allow adequate and
uniform compaction of each lift. Fill should be compacted to at least 90 percent of MDD
(maximum dry density as determined in accordance with ASTM D-1557) to within 2 feet
of subgrade and 95 percent MDD in the upper 2 feet.
The appropriate lift thickness will depend on the fill characteristics and compaction
equipment used. We recommend that the appropriate lift thickness be evaluated by our
field representative during construction. We recommend that our representative be
present dudng site grading activities to observe the work and perform field density tests.
The suitability of material for use as structural fill will depend on the gradation and
moisture content of the soil. As the amount of fines (material passing No. 200 sieve)
increases, soil becomes increasingly sensitive to small changes in moisture content and
adequate compaction becomes more difficult to achieve. During wet weather, we
recommend use of well-graded sand and gravel with less than 5 percent (by weight)
passing the No. 200 sieve based on that fraction passing the 3/4-inch I IBIT L.

(
prolonged dry weather prevails dudng the earthwork and foundation installation phase of
construction, a somewhat higher (up to 10 to 12 percent) fines content will be
acceptable.
Matedal placed for structural fill should be free of debris, organic matter, trash and
cobbles greater than 6 inches in diameter. The moisture content of the fill matedal
should be adjusted as necessary for proper compaction.
Suitability of On-Site Materials as Fill
During dry weather construction, any nonorganic on-site soil may be considered for
use as structural fill, provided it meets the criteda described above in the structural fill
section and can be compacted as recommended. If the material is over-optimum
moisture content when excavated, it will be necessary to aerate or dry the soil pdor to
placement as structural fill.
The workability of matedal for use as structural fill will depend on the gradation and
moisture content of the soil. As the amount of fines increases, soil becomes increasingly
more sensitive to small changes in moisture content and adequate compaction becomes
more difficult or impossible to achieve.
In general, the native granular soils (sand and gravel) encountered in Test Pit 8
located in the northeast portion of the site with less than 10 percent fines (material
passing the No. 200 sieve) are suitable for use as structural fill. This matedal is
comparable to commercial "pit run" sand and gravel. Matedal with less than 5 percent
fines will be suitable as structural fill dudng wet weather conditions.
The silty soils observed on portions of the site and at depth throughout the steep
slope and upland portions of the site, contain high amounts of silt and will be moisture
sensitive. These materials will not be suitable for use as fill dudng wet weather
conditions. Compaction of these soils will be difficult, if not impossible, to achieve dudng
wet weather conditions. Even when propedy compacted, these materials can be easily
disturbed and will soften when exposed to moisture.
We recommend that completed graded-areas be restricted from traffic or protected
pdor to wet weather conditions. The graded areas may be protected by paving, placing
asphalt-treated base, a layer of free-draining matedal such as pit run sand and gravel or
crushed rock (2-inch minus) material containing less than 5 percent fines, or some
combination of the above.
These materials should be placed as structural fill and compacted to at least 95
percent of the MDD. Dudng wet weather conditions, traffic should be confined to
protected areas.
If fill material is imported to the site for wet weather construction, we recommend that it
be a sand and gravel mixture such as high quality pit run with less than 5 percent fines.
CUT AND FILL SLOPES
All job site safety issues and precautions are the responsibility of the contractor
providing services/work. The following cut/fill slope guidelines are provided for planning
purposes.
Temporary cut slopes will likely be necessary dudng grading operations. As a
general guide, temporary slopes of 1.5 to 1 (horizontal to vedical) or flatter may be used
for temporary cuts in the upper 3 to 4 feet of the glacially consolidated soils that are
weathered to a loose/medium dense condition. Temporary slopes of I to 1 or flatter may
be used in the unweathered dense to very dense sands and gravels or till.
These guidelines assume that all surface loads are kept at a minimum distance of
at least °ne half the depth °f the cut away fr°m the t°P °f the sl°pe andL~l~~l~ L

seepage is not present on the slope face. Flatter cut slopes will be necessary where
significant raveling or seepage occurs.
We recommend a maximum slope of 2 to 1 for any permanent cut and fill slopes, if
necessary. Where 2 to 1 slopes are not feasible, retaining structures should be
considered. Fill placed on slopes that are-steeper than 5 to 1 should be "keyed" into the
undisturbed native soils by cutting a series of horizontal benches. The benches should
be 1~ times the width of equipment used for grading and a maximum of 3 feet in height.
Subsurface drainage may be required in seepage areas. Surface drainage should be
directed away from all slope faces. Some minor raveling may occur with time. All
slopes should be seeded as soon as practical to facilitate the development of a
protective vegetative cover or otherwise protected.
FOUNDATION SUPPORT
We recommend that spread footings be founded on the medium dense to dense
native soils or on structural fill that extends to suitable native soils. The soil at the base
of the excavations should be disturbed as little as possible. All loose, soft or unsuitable
matedal should be removed or recompacted, as appropriate. A representative from our
firm should obsen/e the foundation excavations to determine if suitable beadng surfaces
have been prepared.
All footing elements should be embedded at least 18 inches below grade for frost
protection. We recommend a minimum width of 2 feet for isolated footings and at least 16
inches for continuous wall footings. Footings founded as described above can be
designed using an allowable soil bearing capacity of 2,000 psf (pounds per square foot) for
combined dead and long-term live loads. The weight of the footing and any overlying
backfill may be neglected. The allowable bearing value may be increased by one-third for
transient loads such as those induced by seismic events or wind loads.
Lateral loads may be resisted by friction on the base of footings and floor slabs and
as passive pressure on the sides of footings. We recommend that an allowable coefficient
of friction of 0.35 be used to calculate friction between the concrete and the underlying
soil. Passive pressure may be determined using an allowable equivalent fluid density of
300 pcf (pounds per cubic foot). Factors of safety have been applied to these values.
We estimate that settlements of footings designed and constructed as recommended
will be less than 1 inch, for the anticipated load Conditions, with differential settlements
between comparably loaded footings of 1/2 inch or less. Most of the settlements should
occur essentially as loads are being applied. However, disturbance of the foundation
subgrade during construction Could result in larger settlements than predicted.
FLOOR SLAB SUPPORT
Slab-on-grade floors should be supported on medium dense or denser native soils or
on structural fill prepared as described in the Structural Fill section of this report. We
recommend that floor slabs be directly underlain by a minimum 6-inch thickness of coarse
sand and gravel containing less than 5 percent fines. The drainage material should be
placed in one lift and compacted to an unyielding condition.
A synthetic vapor barder should be used for the control of moisture migration through
the slab, in particular where adhesives are used to anchor carpet or tile to the slab. A thin
layer of sand may be placed over the vapor barrier and immediately below the slab to
protect the liner during steel and/or concrete placement.
A subgrade modulus of 400 kcf (kips per cubic foot) may be used for floor slab
design. We estimate that settlement of the floor slabs designed and constructed as
recommended, will be 1/2 inch or less over a span of 50 feet.

SUBGRADE AND RETAINING WALLS
Although subgrade walls are not expected for the proposed construction at the site,
the following is provided as a general guideline if plans change. The lateral pressures
acting on subgrade and retaining walls will depend upon the nature and density of the soil
behind the wall. It is also dependent upon the presence or absence of hydrostatic
pressure. If the walls are backfilled with granular well-drained soil, the design active
pressure may be taken as 35 pcf (equivalent fluid density). This design value assumes a
level backslope and drained conditions as described below.
Positive drainage which controls the development of hydrostatic pressure can be
accomplished by placing a zone of coarse sand and gravel behind the walls. The granular
drainage matedal should contain less than 5 percent fines. The drainage zone should
extend horizontally at least 18 inches from the back of the wall. The drainage zone should
also extend from the base of the wall to within 1 foot of the top of the wall. The drainage
zone should be compacted to approximately 90 percent of the MDD. Over-compaction
should be avoided as this can lead to excessive lateral pressures.
A perforated PVC pipe with a minimum diameter of 4 inches should be placed in the
drainage zone along the base of the wall to direct accumulated water to an appropriate
discharge location. We recommend that a nonwoven geotextile filter fabric be placed
between the drainage matedal and the remaining wall backfill to reduce silt migration into
the drainage zone. The infiltration of silt into the drainage zone can, with time, reduce the
permeability of the granular material. The filter fabric should be placed such that it fully
separates the drainage matedal and the backfill, and should be extended over the top of
the drainage zone.
Lateral loads may be resisted by fdction on the base of footings and as passive
pressure on the sides of footings and the buried portion of the wall. We recommend that
an allowable coefficient of fdction of 0.35 be used to calculate fdction between the
concrete and the underlying soil. Passive pressure may be determined using an allowable
equivalent fluid density of 300 pcf (pounds per cubic foot). Factors of safety have been
applied to these values.
PAVEMENT SUBGRADE
We recommend that pavement subgrades be prepared in accordance with the
previously described site preparation and structural fill recommendations. The upper 2
feet of roadway subgrade should have a density of at least 95 percent of the MDD (ASTM
D-1577).
SITE DRAINAGE
All ground surfaces, pavements and sidewalks should be sloped away from the
residences and associated structures. Surface water runoff should be controlled by a
system of curbs, berms, drainage swales, and or catch basins, and conveyed to the
detention pond and subsequently to an appropriate discharge point.
We recommend that conventional roof and footing drains be installed for all
structures. Drains should be provided behind all retaining walls. The roof drain should not
be connected to the footing drain unless an adequate gradient will prevent a surcharge of
the footing drain.
In paved areas, the catch basins should be perforated so that water in the base
course can drain into the catch basin. Pavement surfaces and open spaces should be
sloped such that surface water runoff is collected and routed to suitable discharge points.

1.1 Location
This letter discusses the wetland determination that concluded that there are no
jurisdictional wetlands present on the South Bible Property located east of 35208 2
Avenue SW in Federal Way, Washington. Specifically, the site i's located in a portion
of the Section 24/25, Township 21 North, Range 3 East of the W.M.'in King County,
Washington.
2.0 METHODOLOGY
Ed Sewall reviewed the property for jurisdictional wetlands on September 14, 1998.
Based on the following methodology, there is no area on the site that meets the
necessary criteria to be considered a wetland. A combination of field indicators,
including vegetation, soils, and hydrology were used to determine wetland edges. The
methodology used to identify any jurisdictional wetlands on the site is described in the
Federal Manual for Identifying and Delineating Jurisdictional Wetlands, 1989 edition
(Unified Federal Manual) as required by the City of Federal Way. The wetland area
identified would also.not be considered a wetland using the methodology described in
the Cotl~'s of Engineers Wetlands Delineation Manual (Environmental Laboratory,
1987), as required by the State of Washington and the US Army Corps of Engineers.
The 1987 Federal Manual requires the use of the three parameter approach in
identifying and delineating wetlands. A wetland should support a predominance of
hydrophytic vegetation, have hydric soils and display wetland hydrology. To be
considered hydrophytic vegetation, over 50% of the dominant species in an area must
have an indicator status of facultative (FAC), facultative wetland (FACW), or obligate
wetland (OBL), according to the National List of Plant Species That Occur in
Wetlands: Northwest (Region 9) (Reed, 1988). A hydric soil is "a soil that is
saturated, flooded, or ponded long enough during the growing season to develop
anaerobic conditions in the upper part". Anaerobic conditions are indicated in the field
by soils with low chromas (2 or less), as determined by using the Munsell Soil Color
Charts; iron oxide mottles; hydrogen sulfide odor and other indicators. Generally,
wetland hydrology is defined by inundation or saturation to the surface~lllllrr

consecutive period of 12.5% or greater of the growing season. Areas that contain
indicators of wetland hydrology between 5 %-12.5 % of the growing season may or may
not be wetlands dePending upon other indicators. Field indicators include visual
observation of soil inundation, saturation, oxidized rhizospheres, water marks on trees
or other fixed objects, drift lines, etc. Under normal circumstances, indicators of all
three parameters will be present in wetland areas.
3.0 OBSERVATIONS -
3.1 Existing Site Documentation
Prior to visiting the site, a review of several natural resource inventory maps was
conducted. Resources reviewed included the King County Soil Survey (Snyder et al.
1973), National Wetlands Inventory Map, and the King County Sensitive Areas Folio.
The inventories did not show any wetlands, streams or wetland soils on or near the site:
3.2 Field Observations
The site has two houses and several barn structures present on the western portion of
the property. The eastern portion of the site is used for horse pasture and the western
quarter of the site is utilized as a yard. We investigated the site and determined that no
area on the site met the necessary criteria to be considered a wetland. An area located
in the central portion of the site was suspected to contain wetland characteristics due to
its low elevation. However, the area did not meet any of the necessary criteria of
hydrology, vegetation and soils required to be a wetland. A data sheet documenting
this data has been enclosed with this letter.
4.0 CONCLUSION
B-twelve concludes that there is no area located on the site that meets the necessary
criteria to be considered a jurisdictional wetland. If you have any questions in regards
to this letter or need additional information, please feel free to contact our office at
(253) 859-0515.

SECTION I
PROJECT OVERVIEW
The proposed project, South Campus Bible School Subdivision, is located east of 21~
Avenue S.W., north of S.W. 353rd Place and west of 19~ Avenue S.W. containing
approximately 4.78 acres. The proposed plat shows 21 single family residential lots.
As requested by a November 4, 1998 letter from the Federal Way Public School, the
following is a student access analysis for this project (see letter in Appendix).
From the above mentioned letter, this project will be served by the following schools:
Sherwood Forest Elementary School - The proposed project is within the 1 mile
radius of this school so the students will walk to school.
Illahee Junior High School - The proposed project is outside of the 1 mile radius
so the students will receive school bus transportation. The current bus stop is
located on 19th Avenue S,W. at 35228.
Federal Way High School - The proposed project is outside the 1 mile radius so
· the students will receive school bus transportation. The existing bus stop is

SECTION II
EXISTING CONDITIONS
The existing student access route conditions are documented with photo which are
located in the Appendix of this report.
The access to Sherwood Forest Elementary School would be along several existing roads.
Students would walk north on 19' Avenue S.W. turning right onto S.W. 351~ Street, than
north on 18~ Avenue S.W. to S.W. 348a Street, continuing on S.W. 349~ Street turning
left on 14th Way S.W. and continuing north to SW 346~ Street and on to Sherwood Forest
Elementary School.
See photos #2 through 11 showing the access route. There are no sidewalks from the
project site to the middle of S.W. 351st Street between 19th Avenue S.W. and 18th Avenue.
S.W. There are sidewalks on both sides of the streets from this point to the school.
The junior high bus stop for Illahee Junior High School students is at 19~ Avenue S.W. at
35228. This stop is across the street, but it is not well defined. (See photo #1)
The high school bus stop for Federal Way High School students is a 19~ Avenue S.W.

Dear Ms. Barker.
This letter ia in respouse to your request for comments on the proposed 2 l-lot single-family development located at thc
35200 Block of 21'* Ave SW. The Federal Way School District is committed to providing the beat education possible for
all students who reside within the District We are concerned with all aspects of facility use and limitations,
transportation, safety and recreational requirements that best support the education of children attending our schools. To
accomplish this, we must give focus to the impact of new housing developments.
Under current boundaries this development would be served by Sherwood Forest Elementary, Illahee Junior High and
Federal Way High School. School service areas are reviewed each year and necessary boundary changes may be made to
accommodate enrollment increases. Sherwood Forest Elementary students would walk to school from this site. Students
attending Ilia/tee Junior High and Federal Way High School would receive school bus transportation from this site. The current
bus stop that would serve Illahee Junior High students is located on I9th Ave SW at 35228. The bus stop for Federal Way High
School students is located at 19th Ave SW and SW 353rd.
Student safety must be considered for all students who would walk to the schools and to school bus stops from this
development. Sidewalks and other planning features that assure safe walking conditions for students are factors the
district must consider as we comment on new development within our service areas. We ask that the developer work with
our staffto prepare a "School Access Analysis" to the elementary, junior high and senior high schools from this proposed
development. Attached are guidelines for preparing this analysis. The developer can request additional information from
Carolyn Calhoon, Transportation Routing Specialist, at 945-5964 or Geri Walker at 945-2071
The most recent Federal Way School District Capital Facilities Plan indicates a student yield of .6088 from single-family
housing. This development could add 12 to 13 new students. This may create a need for additional space, equipment and
staff. This impact is mitigated by the collection of impact fees.
The District appreciates the opportunity to comment on this proposed development and reserves the right for further
comment as additional information becomes available. :
Si$.cerely,
Ged Walker

School Access Analysis
New development creates a need for analysis of student pedestrian safety. The Federal Way
School District would prefer an analysis of walking paths to schools and bus stops from new
subdivisions be prepared by the developer prior to final comments on impacts.
Generally a walking route should be planned to assure that school-age pedestrians from a
neighborhood:
· Cross the fewest number of streets to reduce vehicle-pedestrian exposures
· Walk on sidewalks or paths where available;
· Walk the shortest possible distance on streets without sidewalks or wide shoulders;
· Walk on the lef~ side of the road facing traffic on streets where practicable;
· Avoid high speed, high volume roads and roads with high truck volume.
· Make maximum use of protective techniques (traffic control devices, existing crossing guards
and school patrols.)
· Use easements with walkxvays through parks or other available areas where student safety is
maximized. Walkways and paths must be cleared of vegetation for maximum visibility.
The analysis of walking paths to schools and school bus stop locations
from a new subdivision should include the following information:
· School location
Description of sidewalks, pedestrian paths and shoulders including:
condition and width of shoulder and sidewalks;
whether shoulders are paved, gravel or grass, or non-existent;
whether sidewalks and pathways are immediately adjacent to
the traffic lanes or are separated by a planting strip or other means from moving
traffic; and
}~ the location of drainage or irrigation ditches.
· Location of all crosswalks, including type of crossing protection offered;
· Medians, pedestrian refuge islands and other pedestrian safety features;
· Posted speed limits and warning signs, especially all 20 mph school speed limit zones;
· All stop and yield signs;
· Traffic signals including presence of marked crosswalks and pedestrian signal indication.
Traffic signal timing and phasing for pedestrian crossing.
· Major sight line obstructions as measured from the height of children.
· Bicycle lanes or paths.
· Other relevant pedestrian safety factors observed.

RE: South Bible Subdivision, SUB 98-0007 and SEP 98-0044
Dear Ms. Barker:
Carolyn Calhoon, Transportation Routing Specialist, and I visited the area of this proposed development
located at the 35200 Block of 21't Ave SW. We made a general assessment of the walking conditions for
students who would walk to Sherwood Forest Elementary school from this site.
Sidewalks or improvements to the shoulders are necessary to i~nprove walking conditions in the area adjacent
to this proposed development. There is a portion of sidewalk on the east side of 19th Ave SW directly across
the street from South Bible Subdivision. This sidewalk should be extended north to SW 351~ Street on the east
side. The sidewalk should then be extended east on the south side of SW 351't Street to join with the existing
sidewalk just west of 18~' Ave SW. From this point, there are sidewalks along the entire path to Sherwood
Forest Elementary. If a sidewalk is not required, improvements to widen and delineate a walking path along
this route should be required.
The District appreciates the opportunity to comment on this proposed development and reserves the right for
further comment as additional information becomes available.

Subject: Left mm warrants South Bible Campus Preliminary Plat (SEP98-0044)
Dear Mr. E1-Assar:
At the request of Mr. Dick Schroeder I have conducted a left turn warrant study for the
two intersections outlined in your November 8, 1998 memo. The following presents a
truncated traffic analysis process with the goal to provide an orderly review as to whether
left mrn lanes should be provided on 21 st Avenue SW.
Project Description
The project is a single-family subdivision consisting of 21 lots. The site is an in-fill site
located between SW 351 st Street and SW 353rd Street with access provided from 18th
Avenue SW. The major point of access is expected to be from 21st Avenue SW. It was
assumed for traffic purposes the project could be built and occupied by 2000.
Trip Generation
Trip generation is 'used to determine the magnitude of project impacts on the surrounding
street system. This is typically denoted by the specific number of vehicle trips which
enter or exit a site during a certain time'period. Generation data was taken from the
Institute of Transportation Engineers publication Trip Generation, Sixth Edition. The
specific land use for this site is defined by Single Family Detached Dwelling Units under
the designation of LUC 210. A trip generation summary is shown below in Table 1.

The property owner has not yet applied for developer extension agreement with the District. Said owner will
need to allow approximately 3 to 4 months for plan review and approval.
I did note that general construction activities for utilities were not described in Section 16.b. of the SEPA

NOTE:
The fire flow analysis was performed at a valve cluster
located at SW 353rd P1 & 19th Ave SW. On-site fire flow
estimates would have to be determined during design of the
water system improvements.
This fire flow rate will cause velocities in excess of 10 f/s
within the water distribution system. A fire flow rate less
than 2300 gpm will maintain flow velocities below 10 f/s.
A maximum fire flow rate of 1000 gpm is available for
residential development.
There is no guarantee that the Hydraulic Model results will
represent actual system performance. Model results depict
the theoretical performance of the system under high demand
conditions. Field. measurements should always be obtained for
design purposes.

11/22/1999 1 g/subaras/scatbd/agreement/scatbila
WHEREAS, South King County has a history of multi-jurisdictional transportation planning
dating back to the late 1970's including the Green River Valley Transportation Action Plan
(GRVTAP), which was a multijurisdictional effort coordinated by the Puget Sound Council of
Governments (now Puget Sound Regional Council) and involving King County, the Washington
State Department of Transportation, (WSDOT) and the cities of Auburn, Kent, Renton and
Tukwila; and
WHEREAS, each of the jurisdictions in the South King County area has experienced significant
population growth and economic development in the last decade, and projects continued growth
and development in the future; and
WHEREAS, the cities of Auburn, Kent, Renton, and Tukwila have changed in geographic area
since the late 1970's; and
WHEREAS, the cities of Algona, Des Moines, Enumclaw, Milton, Normandy Park and Pacific
did not participate in the Green River Valley Transportation Area Program (GRVTAP) because
they were outside the study area, but are clearly impacted by traffic congestion problems in the
South County area; and
WHEREAS, the cities of Burien, Federal Way, and SeaTac did not exist during most of the
transportation planning history in South King County; and
WHEREAS, King County, Metro, WSDOT, and the cities of Auburn, Des Moines, Kent,
Renton, Tukwila, and SeaTac have demonstrated, through the South County Area Transportation
Benefit District Steering Committee and program development effort, the benefits that can be
achieved by regional coordination; and
WHEREAS, the enormous cost of many of the needed transportation improvements and their
importance to South King County as a whole demonstrate the need for a cooperative approach to
the planning, financing and construction of these improvements; and
WHEREAS, many of the transportation problems which were identified in GRVTAP still exist
and new transportation management issues have emerged include the Commute Trip Reduction
Act of 1990, the transportation planning and financing requirements of the Growth Management
Act of 1990, and the regional high capacity transportation plan for Sound Move; and
WHEREAS, King County, WSDOT and the South King County cities of Auburn, Des Moines,
Kent, Renton, Tukwila, SeaTac, Burien, Federal Way, Algona, Pacific, Milton, Normandy Park,
Enumclaw, and Black Diamond in 1992 recognized that a cooperative approach to the
transportation problems would facilitate application of the South King County jurisdictions for
funding from the State of Washington and the United States, and in recognition of this, formed
the South County Area Transportation Board (SCATBd) to serve as a central forum for solving
transportation issues affecting the South County area jurisdictions; and
11/22/99 2 g/subareas/scatbd/agreement/scatbila
WHEREAS, the new cities of Maple Valley and Covington have recently been formed and have
been participating in SCATBd discussions.
WHEREAS, the King County Comprehensive Plan for Public Transportation - Long Range
Policy Framework, adopted in 1993, divided Metro service into three geographic subareas for the
purpose of allocating new transit subsidy; and
WHEREAS, the Six-Year Transit Development Plan, adopted in 1995, calls for the three subarea
transportation boards (the Eastside Transportation Partnership, South County Area
Transportation Board, and SeaShore Transportation Forum) to review, refine, and recommend
service priorities to the King County Executive; and
WHEREAS, Sound Transit relies on the three subarea transportation boards to recommend
modifications to Sound Move Plan implementation related services and projects, and
development of future Phase II high capacity planning effort.
NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties
hereto agree as follows:

BACKGROUND
Chair Watkins requested a work session to discuss how the City is handling concurrency requirements of the
Growth Management Act.
DZSCUSSZON
Growth Manaqement Act
The Growth Management Act (GMA) requires some jurisdictions to plan, while others may elect to do so.
In either case, their comprehensive plans are required to contain certain standards. RCW 36.70A.020 cites
the following transportation-related goals:
"(3) Transportation. Encourage efficient multi modal transportation systems that are based on
regional priorities and coordinated with county and city comprehensive plans."
"(12) Public facilities and services. Ensure that those public facilities and services necessary to
support development shall be adequate to serve the development at the time the development is
available for occupancy and use without decreasing current service levels below locally established
minimum standards."
RCW 36.70A.070 outlines mandatory elements of comprehensive plans. Subsection (6) spells out
requirements for a transportation element:
"A transportation element that implements, and is consistent with, the land use element. The
transportation element shall include the following sub-elements:
(a) Land use assumptions used in estimating travel;
(b) Facilities and service needs, including:
(i) An inventory of air, water, and land transportation facilities and services,
including transit alignments, to define existing capital facilities and travel
levels as a basis for future planning;
(ii) Level of service standards for all arterials and transit routes to serve as a
gauge to judge performance of the system. These standards should be
regionally coordinated;
(iii) Specific actions and requirements for bringing into compliance any facilities
or services that are below an established level of service standard;
(c)
(d)
(e)
(iv) Forecasts of traffic for at least ten-years based on the adopted land use
plan to provide information on the location, timing, and capacity needs of
future growth;
(v) identification of system expansion needs and transportation system
management needs to meet current and future demands;
Finance, including:
(i) An analysis of funding availability to judge needs against probable funding
resources;
(ii) A multi-year financing plan based on the needs identified in the
comprehensive plan, the appropriate parts of which shall serve as the basis
for the six-year street, road, or transit program required by RCW 35.77.010
for cities, RCW 36.81.121 for counties, and RCW 35.58.2795 for public
transportation systems;
(iii) If probable funding falls short of meeting identified needs, a discussion of
how additional funding will be raised, or how land use assumptions will be
reassessed to ensure that level of service standards will be met;
Intergovernmental coordination efforts, including an assessment of the impacts of
the transportation plan and land use assumptions on the transportation systems of
adjacent jurisdictions;
Demand Management strategies.
"After adoption of the comprehensive plan by jurisdictions required to plan or who choose to plan
under RCW 36.70A.040, local jurisdictions must adopt and enforce ordinances which prohibit
development approval if the development causes the level of service on a transportation facility to
decline below the standards adopted in the transportation element of the comprehensive plan,
unless transportation improvements or strategies to accommodate the impacts of development are
made concurrent with the development. These strategies may include increased public
transportation service, ride sharing programs, demand management, and other transportation
systems management strategies. For the purposes of this subsection (6) "concurrent with the
development" shall mean that improvements or strategies are in place at the time of development,
or that a financial commitment is in place to complete the improvements or strategies within six
years."
"The transportation element described in this subsection, and the six-year plans required by
RCW 35.77.010 for cities, RCW 36.81.121 for counties, and RCW 35.58.2795 for public
transportation systems, must be consistent."
Planninq Polices
The City's Comprehensive Plan adopted the following policies in response to GMA requirements:
TP7: Establish mobility levels of service appropriate for the alternatives and location.
TP8: Provide funding necessary for transportation needs at appropriate levels of service.
TP11: Coordinate street and roadway improvement programs with appropriate state, regional, and local
agencies.
TP12: Maintain the transportation forecasting model for use in impact analysis, capital facilities planning,
and monitoring of the plan.
TP:L5: Specify an appropriate arterial LOS which balances the economic, ecological, accessibility, and
livability needs of city residents, consumers, employers, and employees.
TP16:
The City's LOS standard shall be E. This is defined herein a volume/capacity ratio less than 1.00 in
accordance with Highway Capacity Manual (1994) operational analysis procedures. At signalized
intersections, the analysis shall be conducted using a 120-second cycle length and level of service
E is defined as less than 60 seconds of stopped delay per vehicle. Where transit or HOV facilities
are provided, the LOS shall be measured by average delay and volume/capacity ratio per person
rather than per vehicle. This standard shall be used to identify concurrency needs and mitigation
of development impacts. For long-range transportation planning and concurrency analysis, a
volume/capacity ratio of 0.90 or greater will be used to identify locations for the more detailed
operational analysis.
TP62:
Modify the development review process by:
(f) Incorporating revised impact analysis procedures which complywith State GMA Concurrency
and other requirements. The revisions need to include revised Level of Service standards.
(g) Streamlining to the extent possible to minimize private development costs. Where
developments are consistent with this plan, they should be allowed to proceed by mitigating
site impacts; developing appropriate components of the HOV, transit, non-motorized and
motorized chapters; and participating in an equitable citywide improvement funding or
mitigation payment program.
(h) Incorporating requirements of the Americans with Disabilities Act.
(i) Requiring explicit consideration of pedestrian and bicycle circulation, as well as parking and
general circulation needs.
TP63:
Adopt a flexible level of service standard which employs a measurement factor that accommodates
demand management to help balance likely levels of growth, with opportunities to create a multi-
modal transportation system.
TP65:
Enhance a non-motorized system by the following actions:
(j) In instances where the citywide system of bike lanes, trail, and sidewalks crosses or abuts
new development or redevelopment, consider requiring the developer to mitigate the impact
of the development on the City's transportation system by constructing bike lanes, trails,
and sidewalks that interface with the existing system.
(k) Coordinate development of the non-motorized system with surrounding jurisdictions and
regional system extensions.
(I) Extend the existing system of City sidewalks to all streets.
TP81: Prioritize transportation projects considering concurrency, safety, support for non-SOV modes,
environmental impacts, and cost-effectiveness.
TP84: Develop a concurrency ordinance by 1998 as required by the GMA consistent with City's adopted
LOS standard.
TP85:
Develop a transportation impact fee by 1999 to simplify development review, assess militation fees
consistently and fairly, improve the City's ability to leverage grant funding for transportation funding,
and provide adequate infrastructure to accommodate new growth.
TP86.'
Adopt interlocal agreements with neighboring jurisdictions to identify methods to assure consistency
between comprehensive plans, and adopt fair and consistent means of addressing the impacts of
growth and development between jurisdictions without undue administrative burdens.
Transportation Modelinq
Forecasts for future traffic volumes are developed using a transportation model. A transportation model is
a computer program wherein land uses and transportation networks are input and traffic volumes are output.
More sophisticated models can also forecast transit, HOV, bicycle, and pedestrian travel demand. Federal
Way's model is based on the Puget Sound Regional Council's model that has been simplified in areas far from
the City and provided more detail within the City.
The modeling process starts with defining the existing transportation system and land uses. The
transportation network is described by the location of major streets, travel speeds, and number of lanes on
each street. The land uses are defined by general types, (e.g. single-family residential, multi-family
residential, retail, office, industrial, and institutional), and is described for any given area called a
Transportation Analysis Zone (TAZ). For any given scenario modeled, there is a four-step process: trip
generation, trip distribution, mode split, and trip assignment.
Trip generation (how many people are coming and going) is calculated for each land use by TAZ. Trip
distribution is the calculation of the relative attractiveness between each TAZ (where are they going?). Mode
split is defining what travel mode will be used by each trip (will they drive, take the bus, walk, bicycle, or t:ar
pool?). Trip assignment is defining each trip's specific route (what streets will they use to get there?). All
of these functions are defined by the relative cost and travel time of each trip with the goal of minimizing
both for each trip. The process is iterative to take into account areas of congestion, transfer times on the
transit system, local cost of parking, etc.
The model is first used to model existing conditions, and is then calibrated to reflect actual conditions as
closely as possible. Once the model is calibrated, future land use assumptions can be input to determine
how traffic generated by new development will use the transportation system. Then, new transportation
projects can be added to the transportation system to determine their effectiveness at reducing congestion
or efficiently moving people and goods.
The City's transportation model was developed in 1992, and was the basis for the transportation element
of the Comprehensive Plan adopted in 1995. A minor update was completed in 1998 for the 1998
amendment of the Comprehensive Plan. However, this did not update land use outside of the City, which
would affect traffic volumes entering and exiting the City. Staff is beginning to prepare for the next update
to be consistent with changes from other jurisdictions in 2000.
Transportation Improvement Plan
The Transportation Improvement Plan (TIP) is a six-year forecast of the City's needed transportation projects
within the financial constraints of the City. GMA as well as federal regulations require that the TIP be
constrained financially. In Washington State, this is complicated by the vagaries of grant funding selection
processes and the amount of funding available by Puget Sound Regional Council, King County,
Transportation Improvement Board, and Washington State Department of Transportation.
As part of the Comprehensive Plan, a 20-year Capital Improvement Program is adopted that includes
transportation projects in the City consistent with the Plan. Annually, staff updates this list and ranks
projects based on the criteria adopted in TP81 of the Plan. A more detailed description of the scoring
process is included in Attachment A.
Level of Service Standard
The level of service standard is adopted in TP16 of the Plan. Its complexity is a result of the level of
precision required to avoid conflicts with development applicants over concurrency, yet still fit within a
concise policy. It has three components: (1) a planning level analysis that reduces the level of effort to
determine where concurrency problems may lie, (2) a more detailed operational analysis, and (3) a
weighting factor that improves the level of service where HOV facilities are provided.
The planning level analysis is intended for consideration of transportation model output for future year traffic
forecasts. In the last Comprehensive Plan amendment, this allowed staffto focus on 27 intersections instead
of analyzing all 219 major street intersections in the City and its Potential Annexation Areas. If the model
output suggests that traffic volumes would be within 90% of capacity, a more detailed operational analysis
is conducted.
The detailed operational analysis is consistent with Highway Capacity Manual procedures. Level of service
for intersections is defined by average delay per vehicle. When this value exceeds 60 seconds, the level of
service is F. A second test is also provided in the adopted policy which specifies that an intersection can't
be over capacity. The relationship between capacity and level of service at intersections is not a linear
function, and in practice, the capacity threshold generally will be reached before the LOS threshold.
:If the operational analysis shows that the intersection does not meet the LOS standard, the third test can
be applied if HOV facilities are present at the intersection. :[n it, the delay per vehicle is adjusted to account
for HOV usage. For instance, if 5000 vehicles per hour use an intersection that operates with 75 seconds
of delay per vehicle, and 50 buses with 40 passengers each and 1000 2-person carpools are using HOV lanes
through the intersection with an average delay of 25 seconds per HOV, the average delay per person is
49.84, hence the LOS standard would be met.
Currently, concurrency analysis is performed only for the evening peak hour. Other hours of the day or week
may have more significant capacity problems in some instances. :[n retail areas, lunch and weekend peaks
may actually be more congested. Freeway on-ramps may be most congested in the morning peak.
Tntersections near schools often peak immediately before schools starts and after school ends for the day.
Whether concurrency testing should occur during other times of day is an important consideration in
developing C:[P updates.

Development Review
The Traffic Division's review of development applications is fairly intensive as it involves all aspects of the
transportation network.
At preapplJcation meetings, Traffic Division staff will provide information on whether a Transportation 1Impact
Analysis (-I-~A) will be required, frontage street improvement requirements, access management
requirements, street and pedestrian connectivity needs, and any safety issues that may be present or created
by the development. For subdivisions, internal street requirements will also be reviewed. The determination
of whether a -I-~A will be required is based on staff's estimate of the number of new evening peak hour trips
generated by the development. ~[f staff is unable to provide an estimate, the applicant will be required to
conduct a trip generation study of similar developments to develop an estimate.
Following the preapplication meeting, if a TIA is required, the applicant would submit a traffic engineer's trip
generation analysis and a proposed trip distribution for the development for staff review. Upon review and
approval, staff provides a Scoping Sheet, documenting the study area to be analyzed in the TIA, TIP projects
expected to be impacted, and any other study requirements. The outline to be used in drafting the -I'~A is
shown in Attachment B. It should be noted that the majority of the traffic data for the City's concurrency
analyses are generated from TIA's.
For SEPA, the applicant would submit a T~A and/or any studies requested at the pre-application meeting to
resolve safety issues or document a request for modification from any standard. Staff reviews and approves
the TIA and based on the data therein, drafts conditions of SEPA approval. SEPA conditions typically include
dedication of right-of-way and mitigation. Frontage improvement required are code-based, and are generally
not included in SEPA conditions.
Mitiqation
Currently, mitigation may occur either by the applicant constructing the needed improvements or the
applicant voluntarily paying a pro-rata share towards improvements shown in the -I-[P, per Code Section 22-
1475. Tf the need for an improvement is documented in the T~A that is not included in the current TIP,
paying a pro-rata share towards the improvement is not an option. The City must spend the pro-rata shares
on the specified TIP project within 5 years of its collection, or refund it to the developer.
The net result of the pro-rata share approach is that it requires government to fund the portion of the TIP
project used by existing traffic, even if the T~P project would not have been required if there were no new
development. Also, since developments that generate less than 10 evening peak hour trips do not contribute
mitigation, only larger developments pay mitigation fees. Furthermore, the larger the development, the
wider the area that is impacted by more than the 10 trip threshold, so larger developments pay more per
new trip generated.
Another alternative currently being considered by Public Work's staff for Council approval in the year 2000
is the Traffic Impact Fee. In this system, mitigation payments for transportation projects is calculated by
the City's cost of TiP projects (subtracting out any grant funding) divided by the number of new trips
forecast for the 6-year T~P for a flat rate per new tip generated. This is more predictable for developers and
fair to all sizes of developments, l~t does not require extensive TIA's to document relatively small impacts,
reducing expenses for applicants and review time for staff.
SUMMARY
Although the City does not have an explicit concurrency ordinance, staff is administering a Concurrency
Management System by maintaining the City's transportation model to identify concurrency needs, and
requiring TIA's for new development, which provides data in identifying new concurrency needs and
identifying SEPA-based pro-rata contributions for -I-~P projects. With the upcoming model update, staff will
be able to develop a more comprehensive proposal for a Traffic :Impact Fee system and integrated
concurrency ordinance, which should provide a fairer and more predictable method of determining
appropriate mitigation for new development requiring less staff time for review. Any guidance from the
Committee on this proposal would be appreciated.

trips in any one approach during any peak hour in the applicable horizon year shall be defined as impacted.
Horizon year: The future forecast year at which the future conditions without the proposed development
are compared to future conditions with the proposed development in order to determine the impacts of the
proposed development on levels of service and capacity. The horizon year for each phase of the
development shall be the greatest extent of the conditions shown in Table 1.

Capacity and Level of Service Analysis. Highway Capacity Manual procedures shall be used.
Ideal saturation flow rates greater than 1900 vehicles per hour of green per lane should not be
used unless otherwise measured in the project vicinity. Signal timing used in capacity analysis
must have a cycle length no greater than 150 seconds. Minimum phase lengths shall allow for
adequate pedestrian crossing time at 4 seconds for walk and 4 feet per second for clearance
(unless majority of pedestrians are elderly or children, in which case longer pedestrian timing
may be required), and be 15 seconds for protected left-tum phases and 10 seconds for
protected/permissive left-tm phases. Arrival types at signalized intersections will be supplied
by the City, if available from the City's TRANSYT-7F models. Queue lengths shall be

VI.
D. Identify Safety-Related Constraints.
Mitigation Measures.
A. Issues to be Considered:
1. Design Vehicle Requirements
2. New Facilities (all modes)
3. Geometric Modifications
4. Traffic Control Modifications
5. Timing of Implementation with Respect to Phases of Development
6. Sight Distance Requirements. If required by staff, intersection sight distance shall be
analyzed in accordance with AASHTO for the site conditions using posted speed limits.
B. Planned and Committed Improvements on Affected Transportation Network. Data will be
supplied by the City.
C. On-Site Improvements. Improvements to streets abutting the development shall be in accordance
with City ordinances and design standards. If frontage improvements would be required on a
street where a City project is proposed in the City's Six-Year Transportation Improvement
Program (TIP), the applicant shall pay a share of that project based on the proportion of the
frontage length to the length of frontage to be constructed by the project or, if the project is
designed, the applicant shall pay a share of the project based on the design engineer's cost
estimate for facilities to be provided on the frontage. Otherwise, the applicant shall provide the
frontage improvement based on the adopted Comprehensive Plan roadway section.
Off-Site Improvements. All improvements shall meet current City standards. Developments
impacting City projects as shown in the City's current 6-Year Transportation Improvement
Program by 10 or more peak hour trips shall either provide the project or pay a pro-rata share of
the project, calculated as the number of new peak hour trips generated by the development
divided by the estimated total peak hour traffic volume at the time that phase of the development
is completed. If a project has been deemed to be fully funded by the Public Works Director, the
pro-rata share will be calculated based on the design engineer's current cost estimate and funding
from federal and state grants. If frontage improvements are also provided on a TIP project, the
cost of the frontage improvements provided by thedevelopment would be subtracted from the
cost of the TIP project before calculating pro-rata share of mitigation for off-site improvements.
Levels of Service. Signalized intersections and all-way stop controlled intersections shall
have a level of service of E or better and a volume/capacity ratio less than 1.000. Other
unsignalized intersections shall have a volume/capacity ratio less than 1.000 on all
movements.
o
Local streets and collectors. The use of traffic control devices to reduce impacts on
residential streets should be negotiated with local neighborhood groups with the goal of
reducing neighborhood infiltration of development-generated spillover traffic.
o
New or revised traffic signals. Signals proposed as mitigation shall meet at least one
MUTCD warrant for signalization in the applicable horizon year. Minor street
movements having an unsignalized level of service of A should not be included in
meeting volume warrants. Warrant analysis for left-tm phasing shall be conducted for
new or revised signals, using the mode recommended by the majority of the following
procedures: LTAP, TRC 212 procedures, and Oregon Department of Transportation
Traffic Signal Policy. Progression analysis using current versions of PASSER II and
TRANSYT-7F shall be provided for new or revised signals if located within one-half
mile of signals existing or listed in the City's current Capital Improvement Program.
4. Turn lanes.
Left-turn lanes. Guidelines from Highway Research Record 211 should be used
to analyze the need for left-turn lanes. Washington State Department of
Transportation Design Manual Figure 910-6 may also be used. Generally, all
signalized approaches should have left-turn lanes where left-tums are permitted
on two-way streets.
b. Right-tum lanes. Washington State Department of Transportation Design Manual
VII.
Fo
Go
Figure 910-10 should be used for right-turn lanes at unsignalized intersections.
Guidelines for Right-Turn Treatments at Signalized Intersections (ITE Journal,
February 1995) should be used for warrants for right-turn lanes at signalized
intersections. City staff will provide copies of these guidelines if requested.
Internal (On-Site) Transportation System. All systems shall meet current City codes and design
standards. Issues to be considered:
1. Design Vehicle Requirements. Turning radii, vertical clearances, etc.
2. Facility Requirements (all modes)
3. Traffic Control Requirements. Signing, striping.
4. Driveway Design. Width, throat length.
5. Parking Requirements
6: Special Features
Transportation Demand Management (TDM) Plans. When TDM pians are proposed as
mitigation measures, the applicant may submit a report to Public Works Traffic Division to
document the success of the TDM Plan one year after occupancy of the development. Upon
approval, the applicant may be refunded any traffic mitigation fees collected for the development
based on the percentage of reduction in vehicular trips, up to 20%.
Analysis of Proposed Mitigation Measures. The greatest horizon years identified in IIII.A for
each phase of the proposed development shall be analyzed.
