HISTORY/BACKGROUND:'
The Subdivision Technical committee of King 'county has
conducted an on-site examination of the subject property and
has discussed the proposed development with the applicant to
clarify technical details of the application and to deter-
mine the compatibility of this project with applicable King
county plans and codes and other official documents regulat-'
ing this development. .
C.
,
As a result of preliminary screening of this plat by BALD,
the applicant sÚbmitted a revised plat on october 4,1989.
The primary modification included relfcation of the access
to a more easterly location. The Subaivision Technical
Committee!also discussed the need to provide a street exten~
sion to Tax Lot 195 immediately south-of the site. The
applicant's agent provided an alternative plat design which
satisfies the road extension required by the Subdivision
Technical Committee (see Attachment 2 for a copy of the
alternative plat design).

THRESHOLD DETERMINATION OF ENVIRONMENTAL SIGNIFICANCE:
Pursuant to the state Environmental ~olicy Act (SEPA);
RCW 4J.21C, the responsible official of.the Building and
Land Developme~t pivision (BALD) issued a threshold
determination of ~on-significance (DNS) for the proposed
development on october 24,1989. This dete~minaticn is
based on the review, of the en-1ironment¡al checklist, and other
pertinent documents, resulting in the conclusion that the
proposal, would not cause probable significant adverse.
,impacts on the environment. Therefore, an environmental
;~impact statement (EIS) was not required prior to proceeding
,with the review process. '
",,/
This determination of n;n-significance was appealed.
However, the appeal decision was not available at the time
this staff report was required ,to be mailed. It is antici-
pated that the SEPA appeal decision will be made prior to
the scheduled plat hearing. The appeal decision will be
'sent to all parties of record identified with both the plat
and SEPA appeal hearing. All interested parties will be
notified of a plat hearing continuanc~ if thé appeal is
granted.

~ - Råg1ar-Indianola is còmposed of about'equal
parts of Ragnar fine sandy loam and Indianolå
loamy fine sand. Slopes are 15-25 ~ercent. These
well-drained soils have moderately rapid permea-
bility in the substratum. Runoff is rapid and the
erosion hazard is severe. The degree of limita-
tions is severe for low building foundations,
severe for shallow excavations due to coarse tex-
tured soil and slope, and severe for septic tank
filter.fields'due to slope and potential for
groundwater pollution/contauination~' There i~ low
to moderate corrosivity for uncoated steel and
concrete. Both soils make fair to good roadfill,
have low compressibility, are pervious when com-
pacted, and a piping hazard existing when used for
dikes, levees, and embankments.
The remaining western edge of the site is
classified AgC.
3.
~ - Alderwood gravely, sandy loam, 6-15\ slopes.
Runoff is slow to medium and the hazard of erosion
is moderate. This soil has a moderate limitation
for foundations, due to a seasonally high water
table and slope.' It has a severe limitation for
septic tank filter fields due to very slow permea-
bility in the substratum.
Hydrography: The site is approximately 1/2 mile south
of Puget Sound/Dumas Bay Park. A seasonal stream tra-
verses northwesterly across the site from the southeast
corner and eventually runs through a culvert under Dash
point Road, which fronts the north property line of the
sitAe ,.
The site lies within the lower Puget Sound sub-basin of
the Puget Sound drainage basin. ' , '

Vegetation: This site is heavily wooded with a second
and third-growth mixture of coniferous and broad-leafed
trees native to the Pacific Northwest.

N/
ANALYSIS:
, . '
.The Subdivision Technical 'committe~ identified t~o issues
during the review 'of thi~ plat. The first issue concerns
access to the proposed s~~~ivi~ion. The subdivision pro-
poses to construct a new roadway access to southwest Dash
point Road (SR 509). The vroposed access shall be subject
~o the review and approval of the Washington state ÛApart-
\~unt of Transportat~on (WSDOT). Primary issues'to be re-
viewed by WSDOT should include entering sight distance and,
intersection spacing with'the existing intersection of
SR 509 and 44th Avenue southwest.
Re1ated to this issue is the typical road improvements
required for perimeter streets along plat frontages. The
current urban road standards for minor arterials, per the
1987 King county Road standards, cannot be directly applied
by King County since Dash point Road is a state highway~
Therefore, WSDO~ should be required to review this plat and
, ..determine improvements to Dash point Road. Also, note that
section K-4 of this report identifies the need for a Class
II bicycle facility along Dash point Road, and that said
road does not currently meet King county's standards for an
urban classified minor arterial. The Subdivision Technical
commit~ee has placed a condition of final approval on this
plat which requires review and approval by WSDOT.
, ' ' '
The second issue'relates to neighborhood circulation through
the adjacent subdivision of TWin Lakes. within the sub-
division of TWin Lakes, S.W. 314th st. functions as a neigh-
borhood collector which accesses 320th Avenue southwest.
southwest 320th street te~inates at the east property line
of the proposed subdivision near SR 509. The subdivision
Technical committee intended to require S.W. 314th st. to
connect to SR 509 through the proposed plat. 'This would
, i~prove' neighborho~d traffic circulation. '. '
DUri~g the réView of the proposed plat,'King county's
traffic engineer was asked to evaluat~ S.W. 314th st. off-
site. As S.W. 314th st. extends easterly, the road grade
becomes very steep (slightlY over 19\) ,and near the crest Qf
this steep grade it intersects with 42nd place southwest.
'The traffic engineer concluded significant safety concerns
wer~ related to the steep grade and sight distance assoc-
iated with southwest 314th street. Following this traffic
'review, the Subdivision Technical committee concluded that
..the connection of S.W. 314th st. to SR 509 through the pro-
posed plat would not be in the public's best interest due to
, these safety concerns.' .
o.
CONCLUSIONS:
The s.Jbject subdivision, as modified by Attachment 2, will
. comply with the goals and objectives of the King County
comprehensive plan and will comply,~with the requirements of
the Subdivision¡and zoning codes and, other official land use

all future roof downspouts and footing
drains, driveways, yard drains; and any other
surface or subsurface drains necessary to
render the lots suitable for their intended
use. Each outlet shall have free-flowing,
positive drainaqe to an approved &~ormwater

6)
g. In some cases, on-site infiltration systems may be
'accepted for detention for the l2ta depending on
soil conditions.' To determine the suitability of
the soil for infiltration systems, a soils report
that includes percolation tests and a soil ~og
taken at 6-foot minimum'\depth shall be submitted'
by a professionalenginecr, or soil specialist.
This shall include~ at a-minimum, information on
soil texture; depth to seà~onal high water\and the
occurrence of mottling and ImpervioUS'layers. The

RE: Sound View Manor
S-89 P 0030
Dear Mr. Hudson:
In response to your inquiry about future plans of the Federa~ Way School
District for school site 163, adjoining our Twin Lakes Elementary School,
it is being held as a junior high site.
The school district does desire to have access from that school site north-
'ward to Dash Point Road.
The elementary school that the above cited development falls in is Twin.
; Lakes. A project the size contemplated could generate up to'twenty-five
(25) elementary students. Twin Lakes is now at capacity. Any new students
may have to be bussed to Other locations in the District. The District
would also like to have the developer address the following concerns:
1. Safe walkways for children. A widened shoulder is not an '
adequate or safe pedestrian walking route. especially for
el~mentary school children.
2. Crossing lights. .
3. Turnoff area for school bus loading and un~oading.
The junior high that wou.1d be affected is Lakota Junior 'High. That school
does have additional capacity at this time.
The senior high attendance a~ea is Decatur High School.
have additional capacity at this time.
That schoo l"'does

FEDERAL WAY
PLANNING AND COMMUNITY DEVELOPMENT
PROPOSED PRELIMINARY PLAT OF SOUNDVIEW MANOR
MAY 17, 1990 - PUBLIC HEARING
STATUS, ISSUES AND RECOMMENDATION
Proposal
To subdivide 9.7 acres of land into 30 single-family residential
lots.

Hearing recommended approval with conditions to
Council
Council Hearing 5/17/90
Report Prepared By:
stephen Clifton - Senior Planner
comparison to Federal Way Codes
In examining this proposal against Federal Way codes, the
application for Soundview Manor generallY meets a majority of
regulations and/or policies. One of the most important issues
for this project is the setback lines from top of slopes. King
county has required a 50 foot setback from the top of bank
(slopes exceeding 40%) with a 25 foot setback allowed only when
a soils report has been prepared. Federal Way's minimum
standards include a 25 foot setback from the top of such slopes.
After reviewing this project, it appears that as much as 75% of
all trees will be removed from the site with the remaining trees
located within the designated Nativ~ Growth Protection Easement
(NGPE). Although King county lacks a tree preservation
ordinance which addresses the retenti~~ of significant trees,
Federal way's Code requires that these trees be identified on a
plan with effort made to save as many significant trees as
possible. Federal way requires that removal of trees exceeding
75% of original significant trees shall result in 25% of such
trees to be replaced. Under Federal way Codes, staff would have
required a tree plan prior to preliminary plan approval to
ensure that an effort has been made to save significant trees.
Under the King county preliminary plat process, additional
studies and/or requirements can be completed after approval of
the preliminary plat but prior to engineering plan or final plat
approval. Due to these additional studies and/or requirements,
significant changes may occur to the layout of the preliminary
plat. Examples of additional information which must be provided
by the applicant and submitted to the King county Engineering
Department prior to engineering and final plat approval include:

state Department of Transportation
Although this is an acceptable process in King County, it is not
the preferred method the city of Federal Way staff intends to
process future Federal Way applications. Our intent would be to
prepare the necessary studies and reports prior to giving
preliminary plat approval.
ISSUES
I.
CIRCULATION AND ACCESS
A.
Connection of plat to roadways in Twin Lakes VI
(prohibited by King County Hearing Examiner).
planning Department comments
According to the Report and Recommendation to the county
Council, the King County Hearing Examiner recommends that access
to S.W. 314th Avenue be denied for several reasons:
a.
The roadway in question, should connection be
approved would exceed a grade of 19-20%. This
exceeds what is allowed by current road standards.
The preliminary report to the King County Hearing
Examiner also states that the crest of this hill
intersects with 42nd. Place S.W. restricting site
visibility. ~
Due to the severity of road grade and~sight distance problems
associated with S.W. 314th street, the King County Technical
Committee concluded that the public's best interest will not be
met by connecting Twin Lakes Division VI and subject project via
S.W. 314th Avenue.
b.
Page 2
city Staff concurs with the Technical Committee's recommendation
and the King County Hearing Examiner condition prohibiting
connection between Twin Lakes Division VI and subject project.
Public safety and welfare should corne first, before
inter-neighborhood circulation concerns.
B.
Access and Improvement of SR-509 and approval from WSDOT,
washington state Department of Transportation.
planning Department comments
According to the King County preliminary staff report and
Hearing Examiner findings, review is required by WSDOT before
access and improvements to SR-509 prior to submittal of
engineering plans to King county for review. Because SR-509 is
a state highway, WSDOT has the ability to veto recommendations
city staff may attach to preliminary plat approval. Requiring
applicant to install a turn lane and/or sidewalks could be a
condition WSDOT apply to the plat if deemed necessary for safety
and improved vehicular travel.
The final plat shall also not be recorded until WSDOT has
approved access and it is documented to King County BALD's
reasonable satisfaction.
If approval of the preliminary plat is granted, Federal Way
City staff recommends the following conditions be applied:
a.
Amend condition #13 of the King county Hearing
Examiner's Report and Recommendation adding: b.
Applicant shall provide a left turn lane and bicycle
lane, in addition to a sidewalk along Dash Point Road
adjacent to site. This requirement shall include
pavement widening, curbs and gutters. This condition
shall also be subject to review and approval by WSDOT.
comments and conditions by WSDOT shall be submitted
with engineering submittals prior to construction.
Applicant shall also provide a copy of WSDOT approved
access and any other conditions of approval that is
documented to King County's satisfaction to the City
of Federal Way.
C.
Dash Point Road (SR-509) / proposed 43rd Avenue S.W.
connection.
\
Per discussion with our consulting firm Wilsey & Ham, it is
important at this time to keep the location of proposed 43rd
Avenue S.W. away from existing 44th Avenue S.W. and Dash point.
44th Avenue S.W. connects to Dash point Road at a 45 degree
angle. Locating proposed 43rd at proposed location as indicated
on the plat map helps to minimize adverse conflicts.
Page 3
D.
Access to property along south edge of site.
Planning Department Comment
The proposed southern end of S.W. 314th street is proposed as a
temporary dead end only. According to condition #12 in the
Report and Recommendation to the King County Council, S.W. 314th
street is intended to connect with public roads serving adjacent
property(ies) to the south. This should help to improve
inter-neighborhood circulation. Adjacent land to the south is
designated as a future Junior High School. S.W. 314th street
may provide some form of future access to the school site.
II.
DRAINAGE - EROSION
planning Department Comment
Per conversations with our consultants, Wilsey & Ham, it appears
that conditions of approval have adequately addressed storm
drainage and erosion concerns expressed by various parties.
In the King county Hearing Examiner's Report and Recommendation
(HERAR) , preliminary Staff Report to Hearing Examiner (PSRHE)
and Appeal of Threshold Determination (ATD) , numerous conditions
have been applied relating to drainage and erosion. The
following briefly summarizes the types of conditions which must
be met prior to engineering plan approval and final plat
approval:
a.
b.
Condition #11 of the HERAR states: 1) that no grading occur
prior to BALD approval, and 2) grading activity shall occur
only between April and september.
condition #16(B) (1) (c) of HERAR requires a lOO-year/24
hour design storm event system. outflow conditions of the
report also refer to a specific outflow rate compared to
storm event which is more restrictive than the 100-year/24
hour design. The formula provided is appropriate to this
site.
This will substantially mitigate adverse impacts from
additional runoff as a result of development.
c.
condition #8 of HERAR requires full compliance with
drainage provisions set forth\~n King county Code 9.04 and
current storm drainage requirements and guidelines as
established by surface Water Manugement, SWM. compliance
may result in the reduction and/or relocation of lots as
shown on the preliminary plat approval.
d.
condition #17 of HERAR requires final engineering plans to
include adequate storm water conveyance to collect all
off-site flows.
Page 4
e.
The applicant is also required to perform a wetland study
off-site along the western boundary. Condition #18 of
HERAR states that if the wetland buffer encroaches within
the boundaries of the proposed subdivision, it shall be
designated as a Native Growth Protection Easement (NGPE).
This would then require modification to the preliminary
plat.
The Federal way Community Development Department concurs with
all conditions pertaining to wetlands, drainage and erosion
referenced in the above mentioned documents.
III. MAINTENANCE OF STREAM CORRIDOR - (set aside Tract C)
planning Department Comments
According to the plat map submitted and Recommendation from the
King county Hearing Examiner, a seasonal stream traverses the
site. In order to ensure the continued functioning of this
drainage course, condition #14 from the Recommendation Report
addresses this issue. This stream corridor is also part of the
NGPE (Native Growth Protection Easements). conditions #14, 15,
19, 20, and 24-26 address the restriction or removal of
vegetation within all NGPE areas in particular along the stream
banks.
A concern over who would be responsible for the continued
maintenance of open space areas and the storm detention system
is addressed as follows:
a.
condition #28 of the Hearing Examiner's Report
provides for the ownership and maintenance of open
space by an acceptable homeowners or workable
association.
According to condition #29 of the Hearing Examiner's Report,
Tracts D, E and F are to be incorporated into Tract C, lot NO.
27, or conveyed to adjacent property owners with lot line
adjustments completed prior to recording. Due to
reconfiguration required by King county BALD conditions, city
staff recommends a change to this condition as stated below.
If approval of the preliminary plat is granted, Federal Way city
staff recommends revising Conditions #28 and #29 of the Hearing
Examiner's Report and Recommendations to read:
1.
Amend condition #28 to rea~k The Homeowners
Association and/or property owners of Soundview Manor
shall have an ongoing obligation to maintain the
entire drainage system and open space. The city is
hereby granted a license to come upon the premises to
perform such maintenance in the event that soundview
Manor Homeowners Association and/or property owners do
Page 5
not properly maintain the drainage system or open
space. In the event that the city is required to
perform such maintenance work, after notice to
soundview Manor Homeowners Association and/or property
owners and the failure of Soundview Manor Homeowners
Association and/or property owners to perform the
required work, the city may perform said work and
shall charge back to soundview Homeowners Association
and/or property owners the cost of performing said
work times a multiplier of 2. Soundview Manor
Homeowners Association and/or property owners shall
pay within thirty (30) days the amounts invoiced by
the city for performing such required maintenance
work. If Soundview Manor Homeowners Association
and/or property owners fails to pay, the city is
authorized to place a lien on the property.
2.
Amend condition #29 to read: Tracts F, G and H shall
be incorporated into Tract C and shall be placed on
the face of plat prior to recording of the plat.
3.
To ensure that citizens are made aware of the
importance of a NGPE area, an interpretive sign will
be posted along the edge of the NGPE (Abutting Dash
Point Road) area describing the importance of the area
and listing prohibited activities, i.e. no cutting of
any vegetation, no dumping, etc. Exact language, sign
design and construction shall be worked out between
the city of Federal Way staff and applicants prior to
recording of final plat.
IV.
SLOPES
1.
50 foot setback from top of slope.
Planning Department Comments
According to the Hearing Examiner's and preliminary staff
Report, the applicants are required to determine the top of bank
and 40% slopes by conducting a field survey. Once established,
a 50-foot Building setback Line (BSBL) shall be defined from the
top of bank. This can be reduced to 25 feet with the submittal
of a satisfactory soils report. conditions #20 and #24 of each
report specifically address this issue. The conditions also
prohibit structures, fill or obstru~~ion, including decks and
patios beyond the setback line. The~ßstablishment of this
setback line could result in changes ~~ the plat, e.g. less lots
or reconfiguration. Final determination will result when
studies or surveys have been completed. It is City staff's
opinion that the Building Setback issue has been adequately
addressed. Federal Way minimum standards include a 25 foot
setback from such steep slopes.
Page 6
V.
OPEN SPACE
1.
Dedication of open space in subdivisions.
Planning Department Comments
According to the King County Subdivision Ordinance, Chapter
19.38.020, every subdivision final approval within the zone of
subject development shall be contingent upon reservation or
dedication of land for the open space and recreational needs of
its residents or payment of a fee-in-lieu thereof. The
developer may either reserve or dedicate land or make payment of
a fee-in-lieu thereof pursuant to Chapter 19.38. This
requirement does not apply to lots exceeding 35,000 square feet
and subdivisions of less than ten acres. The fee-in-lieu of
on-site open space is typically calculated by multiplying the
following two factors:
a.
150 percent of the average assessed per unit area of
land within the boundaries of the subdivision;
b.
The gross land areas within the subdivision multiplied
by 5.5% which is the required open space dedication
for RS;SR 7200 zoning.
Although the preliminary plat of soundview Manor is under 10
acres, the King County Hearing Examiner Report and
Recommendation condition #27 requires an in-lieu-of fee for
space. If preliminary plat approval is granted, city staff
recommends modifying condition #27 as follows:
open
1.
Amend condition #27 to read: the applicant shall
comply with K.C.C. 19.38 by paying a fee to the City
of Federal Way Parks Division in-lieu-of providing
on-site open space (K.C.C. 19.38 establishes the
formula for said fee amount).
VI.
SCHOOLS
1.
Access to school site south of proposed development.
planning Department Comments
According to condition #12 of the Hearing Examiner's Report to
King county Council, access via s.~~ 314th street is intended to
connect with public roads serving adjacent property(ies) to the
south. This could provide access to'~he school if deemed
necessary when the school is developed. The planning Department
concurs with this condition to provide access to property south
of subject proposal.
2.
Overcrowding of school.
Page 7
planning Department Comments
Per a conversation with school officials from the Federal Way
School District, they are not opposed to this development. The
school district as stated in the Hearing Examiner's
Recommendations has not indicated that it cannot handle added
students. At this time, an important issue with the school
district is the redefining of boundaries to ensure that a
majority of students go to a school nearest a student's
residence. Boundaries have been established on previous
densities and/or student populations. Currently the school
district is looking at redefining these boundaries.
In regard to pedestrian circulation, the applicants are
providing walkways, and full street improvements for subject
development, for those choosing to use them. Elementary and
eventually Junior High students will not have to use 47th Avenue
S.W. and Dash Point Road for access to schools south of proposed
development. Access would be from S.W. 314th street.
RECOMMENDATION
The city of Federal Way Department of Community Development
Staff recommends the subject subdivision, be granted preliminary
approval subject to conditions as listed in the Hearing
Examiner's Report and Recommendation to the County Council
(2-14-90), and in addition, City staff also recommends the
following conditions be applied:
1.
Page 8
Amend condition #13 of the Hearing Examiner's Report
and Recommendation to add: b. Applicant shall also
provide a left turn lane and bicycle lane, in addition
to a sidewalk along Dash Point road adjacent to site.
This requirement shall include pavement widening,
curbs and gutters. This condition shall also be
subject to review and approval by WSDOT shall be
submitted with engineering submittals prior to
construction.
Applicant shall also provide a copy of WSDOT approved
access and any other conditions of approval that is
documented to King county's satisfaction and the city
of Federal way.
2.
\x
Amend condition #28 to read: the Homeowners
Association and/or property\~wners of soundview Manor
shall have an ongoing obligation to maintain the
entire drainage system and open space. The City is
hereby granted a license to come upon the premises to
perform such maintenance in the event that Soundview

Homeowners Association and/or property owners the cost
of performing said work times a multiplier of 2.
soundview Homeowners Association and/or property
owners shall pay within thirty (30) days the amounts
involved by the city for performing such required
maintenance work. If Soundview Manor Homeowners
Association and/or property owners fails to pay, the
city is authorized to place a lien on the property.
Amend condition #29 of the Hearing Examiner's Report
and Recommendation to read: Tracts F, G and H shall be
incorporated into Tract C and shall be placed on the
face of plat prior to recording of the plat.
Amend condition #27 of the King county Hearing
Examiner's Report and Recommendation to read: The
applicant shall comply with K.C.C. 19.38 by paying a
fee to the City of Federal way Parks Division
in-lieu-of providing on-site open space (K.C.C. 19.38
establishes the formula for said fee amount).
5.
To ensure that citizens are made aware of the

If it is determined (for reasons of safety) by King
county and WSDOT that the most suitable location for a
new access road to southwest Dash point Road (SR 509)
conflicts with the stream corridor, then additional
encroachment into the stream corridor and piping of
the stream may be allowed between Southwest 3l4th
Place and SR-509.
The stream corridor may be utilized as a retention/
detention (R/D) facility, if the following conditions are
satisfied:
a.
The applicant shall retain a qualified biologist to
work with the professional engineer in the design of
the R/D facility.
b.
The final design of .the R/D facility shall ensure the
continued maintenance of the existing vegetation types
and shall minimize th¿ disturbance to existing stream
corridor. Any proposed disturbance to the existing
vegetation shall include an enhancement and
revegetation plan prepared by a qualified biologist.
The plan shall be subject to the review and approval
of Building and Land Development Division.
c.
The design of the R/D facility shall include a
permanent sediment trap or pond at all storm water
outfalls into the stream. These sediment traps and
ponds shall be located outside of the NGPE.
d.
The final engineering plans and recorded plat shall
cover the R/D facility with a drainage easement.
e.
The final design shall be subject to the review and
approval of the Building and Land Development Division
wetland scientist and review engineer.
A.
To enhance water quality, storm water facilities shall
be designed with wet ponds and vegetated swales for
biofiltration.
B.
A drainage plan prepared by a registered professional
civil engineer must meet each of the following
conditions:
I .
Surface and storm water runoff detention shall be
computed using a scs-based hydrograph method (or
other method as subsequently approved by King
county). The performance of proposed detention
facilities shall be suChj that discharge from the
developed area shall be no more than:
!.
Fifty percent of the¡:predeveloped forested
2-year/24-hour:release rate for design storm
events up to and including the 2-year/24-hour
design storm event; I';
"
i:
a.
b.
The forested ,2-:year/24-hour release rate for
design storm e~ents ',greater than the
2-year/24-hour design storm .event and up to
ana including the lO-year/24-hour design
storm event; and
\.
c.
The forested lO-year/24-hour release for
design storm events greater than the
10-year/24-hour design storm event and up to
and including the 100-year/24-hour design
storm event.
17.
S89PO030-Plat
Page 6
These rate controls may be modified if discharge is
conveyed via a continuous welded storm pipe to a
suitably stablized release point with adequate energy
dissipation below the area of severe erosion potential
(if possible).
c.
For purpose of the computations required above,
pre-development conditions will be assumed to be
totally forested, and developed conditions will assume
100\ removal of forest canopy within the area of the
development (unless expressly prohibited by recorded
easement or restriction) as well as existing,
proposed, and anticipated impervious surfaces.
Detention facilities must be located to accommodate
surface and storm water runoff from all areas of
planned or potential clearing and/or construction.
D.
point discharge from,detention systems will be only
into drainage channeis that previously conveyed
surface and storm water runoff in the pre-development
state, as indicated by the presence of a defined
channel bed and channel banks. No point discharge
shall be permitted onto or upstream of steep slopes
where erodible granular soils lie anywhere downstream
of that point discharge. Dispersed discharge, onto
undisturbed low-gradient uplands may be evaluated as a
potential alternative. An undisturbed buffer between
the dispersed discharge and the steep side slopes must
be adequate to ensure infiltration of surface and
storm water runoff into the ground. Determining and
documenting that adequacy is the responsibility of the
applicant's professional civil engineer.
Undeveloped property exists adjacent to and upstream of
the proposed subdivision. TO provide for potential future
development, the final engineering plans shall include
adequate storm water conveyance to collect all off-site
flows.
18.
An uninventoried wetland is located off-site and adjacent
to the western boundary of the proposed subdivision. The
following conditions shall be satisfied with respect to
this wetland.
a.
A wetland study shall be prepared by a qualified
wetland biologist. The study shall include field
delineation of the wetland edge, classification of
wetland type, and a discussion of the functions and
values of the wetland. The wetland edge shall be
mapped by a licensed land surveyor. The study shall,
be subject to the revie~ and approval of the Building
and Land Development Division's wetland biologist, and
shall be included with ,the submittal of the
engineering plans.'
b.
If the wetland or the' wetland buffer encroach within
the boundaries of th~ proposed subdivision, it shall
be designated as a Native Growth protection Easement
(NGPE).
c.
> ~
An additional IS-foot building setback line (BSBL)
shall be delineated adjacent t~ the wetland buffer and
shown on the approved engineerA.g plans and recorded
final plat, if the BSBL encroaches within the boundary
of the proposed suhdivision.

The following statement shall be shown on the approved
engineering plans and recorded final plat:
Building setbacks and Native Growth protection Easements
structures, fill and obstructions (inclUding, but not
limited to decks, patios, outbuildings, or overhangs
beyond 18 inches) are prohibited within the BSBL and
restricted floodplains (if applicable), and within the
Native Growth Protection Easements(s) as shown.
Dedication of a Native Growth protection Easement (NGPE)
conveys to the public a beneficial interest in the land
within the easement. This interest includes the
preservation of native vegetation for all purposes that
benefit the public health, safety and welfare, including
control of surface water and erosion, maintenance of slope
stability, visual and aural buffering, and protection of
plant and animal habitat. The NGPE imposes upon all
present and future owners and occupiers of the land
subject to the easement, the obligation, enforceable on
behalf of the public by King county, to leave undisturbed
all trees and other vegetation within the easement. The
vegetation within the easement may not be cut, pruned,
covered by fill, removed or damaged without express
permission from King county, which permission must be
obtained in writing from the King County Building and Land
Development Division or its successor agency.
Before and during the course of any grading, building
construction, or other development activity on a lot
subject to the NGPE, the common boundary between the
easement and the area of development activity must be
fenced or otherwise marked to the satisfaction of King
county.
20.
steep slopes (40% or greater) appear to exist on portions
of Tract C, as shown on the proposed preliminary plat
received october 4, 1989. TO protect the steep slopes and
the property adjacent to it, the following conditions
shall be satisfied:
a.
Prior to final engineering plan approval, a licensed
land surveyor shall determine the limits of steep
slopes which exist within the proposed subdivision.
b.
The top and toe of the slope shall be delineated on
the final engineering plan and recorded plat.
c.
The areas of steep slopes (40% or greater) shall be
designated with a NGPE on the final engineering plans
and recorded subdivision.

Exhibit A
~~~rm Drainage Requirements
(Portion only).
a.
BALD approval of the drainage and roadway plans is
required prior to any construction.
b.
A separate ESC plan for this project shall be submitted
with the engineering plans. The plan shall show areas to
be cleared (limits of clearing) and provide a schedule for
construction (construction sequence).
c.
Retention/detention (R/D) facilities shall be located in
tracts, unless located within improved King County
rights-of-way. Maintenance access shall be provided to
all facilities. This will require a IS-foot access
roadway to all manholes (R/D). Access must also be
provided for maintenance of the entire pon~.
d.
Prior to recording of the final plat those portions of the
retention/detention facility necessary to control the
flows discharging from the site shall be constructed and
operational.
e.
Oil/water separation facilities shall be provided at each
point of permanent storm drainage release from the site so
contaminants do not enter natural drainage features. In
addition to standard King County oil/water separators, the
applicant is required to provide biofiltration prior to
discharge of stormwater into any sensitive area (e.g.,
streams, wetlands, lakes, etc.). Such biofiltration
includes 200 feet of broad, flat-bottom, grass-lined
swales, or equivalent systems.
f.
Drainage outlets (stub-outs) shall be provided for each
individual lot, except for those lots approved for
infiltration by King county. Stub-outs shall be shown on
the engineered plans and shall conform to the follOwing:
1.
Each outlet shall be suitably located at the lowest
elevation on the lot, so as to service all future roof
downspouts and footing drains, driveways, yard drains,
and any other surface or subsurface drains necessary
to render the lots suitable for their intended use.
Each outlet shall have free-flowing, positive drainage
to an approved stormwater conveyance system or to an
approved outfall location.
2.
outlets on each lot shall be located with a
five-foot-high, 2. x 4" stake marked "storm. or
.drain.. The stub-out shall extend above surface
level, be visible and be secured to the stake.
3.
pipe material shall conform to underdrain
specifications described in KCRS 7.04 and, if
non-metallic, the pipe shall contain wire or other
acceptable detection feature.
4.
Drainage easements are required for drainage systems
designed to convey flows through more than one lot.
S.
The developer and/or contrac~Dr is responsible for
coordinating the location of a~1. stub-out conveyance
lines with respect to the utililiUes (e.g., power, gas,
telephone, television).
6.
All individual stub-outs shall be privately owned and
maintained by the lot homeowner.
g.
In some cases, on-site infiltration systems may be
accepted for detention for the lots depending on soil
conditions. To determine the suitability of the soil for
infiltration systems, a soils report that includes
percolation tests and a soil log taken at 6-foot minimum
depth shall be submitted by a professional engineer or
solI specialist. This shall include, at a minimum,
information on soil texture, depth to seasonal high water
and the occurrence of mottling and impervious layers. The
report shall also address potential down gradient impacts
due to increased hydraulic loading on slopes and
.structures. Soil permeaqility data obtained from the
design of the septic system may be used for the drywell
retention system, provided data is submitted verifying
that no impervious layer exists within 6 feet of the soil
surface. If the soils report is approved, the
infiltration systems shall be installed at the time of the
building permit. A note .to this effect shall be placed on
the map page of the recorded document. The drainage plan
and the recorded document shall indicate each lot approve
for infiltration.
h.
Include with the drainage plan a downstream analysis.
This analysis must extend for a minimum distance of 1/4
mile from the point of release of each flow discharging
from the site. The analysis must address any existing
problems with flooding, capacity, overtopping, scouring,
sloughing, erosion and sedimentation of any drainage
facility, whether natural or man-made. Probable impacts
due to construction of the project must also be addressed
with respect to these same concerns. Where this analysis
reveals more restrictive conditions, more stringent
drainage controls may be required than would otherwise be
necessary for a project of this type. These controls may
include additional on-site rate and/or volume controls,
off-site improvements, or a combination of both. Any
off-site improvements will require the approval of all
affected property owners. .
i .
Current standard notes and ESC notes, as established by
BALD engineering review, shall be placed on the engineered
plans.
j.
The following notes shall be provided on the map page of
the recorded document:
1.
For all lots:
.All building downspouts, footing drains and drains
from all impervious surfaces such as patios and
driveways shall be connected to the approved permanent
storm drain outlet as shown on the approved
construction drawings I on file with the
Department of Public Works. The plan for these
connections shall be submitted with the application
for any building permit. All connections of the
drains must be constructed and approved prior to the
final building inspection approval..
2.
For any lots approved for individual infiltration:
I.r
"Individual lot infiltrationcsystems shall be
constructed at the time the 're~idence is constructed
and shall comply with plans on~ile at the public
Works Record Center.. .

On April 25, 1989, the applicant (respondent) Overson
Construction Company applied for preliminary approval of a
subdivision of 9.7 acres into 29 lots at a site on the
south side of Dash Point Road S.W. in Federal WaY' and Land
Following its review of the proposal the Building
Development Division issued a threshold determination of
nonsignificance pursuant to the State Envi�onmental Policy
Act on October 29, 1989. On November 7 and 8, 1989,
appeals were filed in a timely fashion by M�. Richard
Burris, representing the Development Impact Resistence
Exercise (a Washington nonprofit corporation) and Mr.
Perry Jones, et al., residents in the community of the
vicinity of the p�oposed plat. The subject property
received p�eliminacy approval for a planned unit
development of 48 dwellinq units in 1979 (File No.
209-79-P). That approval was extended until December 9,
1983, by the County Council on October 4, 1982 (Motion No.
5581), but the project was never completed. The present
proposal is for single family detached homes.
Foremost among the concerns expressed by appellants is the
possibility oE a connection of S.W. 314th Stceet in the
subdivision of Twin Lakes Division VI, to the streets in
this plat. While no such connection has been proposed by
the applicant the Subdivision Technical Committee has
considered such a road alignment to provide
inter-neighborhood circulation and prevent the necessity
of traffic between the two s�bdivisions being required to
travel miles to go to a point several hundred feet away.
Residents point out that the possible street connection
as een the subject of e ensive co during tlie
consi eration oE other land use applications in_t
vicinity and th t he county_ha pie decided no t to
a ow suc a connect on. The roadway in question would be
at gCades of 19-20$, which exceeds what is allowed y
Eoday s road standards. Neighbors point out that in its
previous consideration of this roadway, the Department of
Public works determined in 1979, that it would be
extremely hazardous to allow such a connection given the
si9ht distance to the west at this location. In view of
this and other considerations, the Building and Land
Development Division has notified t �h a � X it i would y not be in
memorandum dated January 24, 1990,
the best interest of the public safety to continue
Southwest 314th as a throuqh street. The�efore, this
recommendation has been withdrawn.
9. The Federal Way School District owns a site being held
a futuce junior high school adjacent to the sbuth.of th
proposed plat. The District has requested that this
applicant furnish access from the school site notthward
Dash Point Road. Residents, on the assumption that suc
an access would be a thcough street, have argued that i
for
to
SB9PO030
Page 3
would constitute a safety hazard for children in the
existing adjacent
grade school and other pedestrians in the neighborhood.
such an extension, it is argued, would constitute a
significant adverse impact on the environment.
5.
The school district estimates that 25 elementary school
students would be generated by the proposed project. It
notes that any new students may have to be bussed to other
locations in the district. The junior high school that
would be impacted by the proposed development has adequate
capacity at this time. Similarly, senior high school
students would attend Decatur High school which has
additional capacity at this time. Neighboring residents
stated that schools are dangerously crowded and that the
approval of development that would increase school
population would constitute a significant adverse impact
on the environment. The applicant's representatives have
noted that the school district's boundaries are adjusted
each school year to maximize bussing efficiency.
Approximately 4,135 students were bussed in the current
school year. Two new elementary schools will be built by
the year 1991, and one is scheduled to open in the Fall of
1990. Therefore, it is not anticipated by the applicant
that the school district will not have sufficient capacity
to serve students from the proposed subdivision.
6.
Appellants have cited what they perceive as extreme
erosion hazards in the vicinity which could result in the
proposed project having a significant adverse impact on
the environment. Reference is made to severe erosion
problems that occurred ~ith the development of Twin
Lakes. The velocity of the water is said to be so great
that it sucked the culvert from underneath the road and
washed away trees and four acres of soil. The nearby plat
of stonebrook is said to have caused severe siltage for
four miles along water courses and when asked the King
county Building Division responded that they could~
closely supervise construction of detention facilities in
pew subdivisions.. ïHïen E he-" plat inspectors are done,
building inspectors take over and do not devote much
attention to such facilities. The King County sensitive
Area Map Folio on map 6 indicates that erosion seismic
potential exists on the site and thåt there is a type 5
(unclassified) stream corridor on site.
The applicant's engineers concede that the soils on the
site are sandy and will tend to liquefy. They have agreed
with the Building Division to limit grading to the dry
months of the year (April - september) in accordance with
the grading plan to be approved by the county. Under
current standards the drainage system will be designed for
25-year/24-hour storm with a two year release rate. Thus,
the detention system will be four times the size of those
installed three years ago. The drainage basin impacted by
the plat is largely confined to the site of the plat
itself with a small portion off the site, flowing toward
Twin Lakes Division VI. It is so small that the volume of
water will be minimal.
7.
The proposed subdivision is locaterl just ~pstream and
south of Dumas Bay park. Dumas Bay ~ing county park is
one of the few remaining saltwater/f~shwater ecosystems
capable of supporting wildlife in the King county area.
It is a stop for migratory birds on their annual migration
and a nesting area for birds native to the area. There
are at least 35 blue heron that have been observed in
Dumas Bay park vicinity along with many nests. canadian

KCC 20.44.120 provides as follows:
KCC 20.44.120 Appeals. ~. Appeals of threshold
determination shall be conducted by the zoning and
subdivision examiner pursuant to KCC 20.24.0BO, subject to
the following:
1. Only one appeal of each threshold determination
shall be allowed on a proposal.
2. As provided in RCW 43.2lC.07S(3)(d), the decision
of the responsible official shall be entitled to
substantial weight.
Appeals of Threshold Determination shall be conducted
by the Zoning and subdivision Examiner pursuant to
KCC 20.24.0BO subject to the following.
*.*
CONCLUSIONS:
1.
AS set forth above, the King county code section 20.44.120
and RCW 43.2lC.07S(3)(d) provide that the decision of the
responsible official in making a threshold determination
is entitled to substantial weight. The burden is '.
therefore on the appellants to prove that the Division
erred in its threshold determination of nonsignificance.
Given the mitigating measures adopted below, I cannot
conclude that the Division's determination was in error or
that an environmental impact statement should be required
for the proposed project for the reasons set forth more
fully below.
2.
Insofar as the Building Division has withdrawn its request
to connect Southwest 3l4th Street between the proposed
subdivision and Twin Lakes No. VI, the main concern of the
appellants appears to have been met. In order to
acknowledge this revision a mitigating condition to that
effect will be adopted below.
3.
Whether or not a roadway should be extended to the school
district property to the south will be the proper subject
of further testimony at a preliminary plat hearing. On
the basis of the evidence before me, I cannot conclude
that the Building Division has erred in requesting such an
extension. There is, however, insufficient information in
the record to make a determination at this time for what
purpose the school district desirè~ the connection or what
the potential safety impacts of sJch a ro~dway might be.
Interested parties may wish to assuip that the school
district appears to justify its requ~t at the preliminary
plat hearing.
4.
There is no basis in the record to conclude that the
Building Division has erred in its determination that the
proposed project will not have a significant adverse
SB9POO30
VagI! ~
impact on the Federal Way School District. As noted by
the applicant's representatives, the School District
commonly busses students to achieve the optimum classroom
size throughout the District. The School District has not
indicated that it cannot handle added students from this
project: and, as noted above, it appears that additional
schools will be on line by the time the subject project is
likely to be built out two years from noW. At any rate,
it is my conclusion that the 25 added students that the
District predicts from this project do not constitute a
significant adverse impact requiring an environmental
impact statement for the proposed subdivision.
5.
It appears that significant erosion problems have occurred
in the vicinity of this plat because of the nature of the
soils and the steep grades in the area. The Building and
Land Development Division has acknowledged that the site
will require consideration pursuant to the Sensitive Areas
Ordinance. However, no recommendation has been made
beyond the suggestion that grading only occur during the
dry months of the year. However, in order to avoid the
kind of problems that have been described in the Findings,
above, the project will be required to design to a
lOO-year storm standard, with a two-year release rate
which should substantially mitigate any adverse impact
from additional runoff as a result of development.
6.
other arguments and contentions of the appellants have
been considered and are denied.
DECISION:
The threshold determination of nonsignificance is withdrawn and
a mitigated determination of nonsignificance is hereby
substituted. Mitigating conditions are as follows:
1.
There will be no connection of roadways in this pla~,to
the subdivision of Twin Lakes VI.
2.
No grading shall occur on site until approval of the
grading plan by the Building and Land Development
Division. Grading activity will occur only between the
months of April and september.
3.
A.
To enhance water quality, storm water facilities shall
be designed with wet ponds and vegetated swales for
biofiltration.
B.
A drainage plan prepared by a registered professional
civil engineer must meet each of' the following
conditions:
1.
Surface and storm water runoff detention shall be
computed using a scs-based hydrograph method (or
other method as subsequently approved by King
county). The performance of proposed detention
facilities shall be such that discharge from the
developed area shall be no more than:
a.
Fi f ty pe r cen t 0 f t he\;~pr edeve loped f 0 res ted
two-year/24-hour release rate for design
storm events up to and~nclUding the
two-year/24-hour design storm event:
b.
The forested two-year/24-hour release rate
for design storm events greater than the two
year/24-hour design storm event and up to and
including the lo-year/24-hour design storm
event: and
"
'..'
"
S89PO030
page 6
The forested 10-year/24-hour release for
design storm events greater than the
10-year/24-hour design storm event and up to
and including the 100-year/24-hour design
storm event.
c.
These rates controls may be modified if discharge is
conveyed via a continuouS welded storm pipe to a
suitably stablized release point with adequate energy
dissipation below the area of severe erosion potential
(if possible).
For purpose of the computations required above,
pre-development conditions will be assumed to be
totally forested, and developed conditions will assume
.100\ removal of forest canopy within the area of the
development (unless expresslY prohibited by recorded
easement or restriction) as well as existing,
proposed, and anticipated impervious surfaces.
Detention facilities must be located to accommodate
surface and storm water runoff from all areas of
planned or potential clearing and/or construction.
C.
point discharge from detention systems will be only
into drainage channels that previouslY conveyed
surface and storm runoff in the pre-development state,
as indicated by the presence of a defined channel bed
and channel banks. No point discharge shall be
permitted onto or upstream of steep slopes where
erodible granular soils lie anywhere downstream of
that point discharge. Dispersed discharge, onto
undisturbed low-gradient uplands may be evaluated as a
potential alternative. An undisturbed buffer between
the dispersed discharge and the steep side slopes must
be adequate to ensure infiltration of surface and',
storm water runoff into the ground. Determining and
documenting that adequacy is the responsibility of the
applicant's professional civil engineer.
