HISTORY/BACKGROUND:
The Subdivision Technical Committee of King County has
conducted an on-site examination of the subject property.
It has also discussed the proposed development with the
applicant to clarify technical details of the application
and to determine the compatibility of this project with
applicable King County plans and codes and other official
documents regulating this development.
C.
THRESHOLD DETERMINATION OF ENVIRONMENTAL SIGNIFICANCE:
Pursuant to the state Environmental Policy Act (SEPA),
RCW 43.21C, the responsible official of the Building and
Land Development Division (BALD) issued a threshold determi-
nation of non-significance (DNS) for the proposed develop-
ment on November 21, 1989. This determination is based on
the review of the environmental checklist and other perti-
nent documents, resulting in the conclusion that the pro-
posal would not cause probable significant adverse impacts
on the environment. Therefore, an environmental imp3ct
statement (EIS) was not required prior to proceeding with
the review process.

Avoid dumping soil, vegetative waste, or debris
over steep slopes.
Denuded ground cover should be protected within
15 days of final di~turbance of a particular area.
6.
7.
Seeding, mulching, netting and mechanical forms of
protection can be used to stabilize exposed soils.
All stockpiles of excavated soil or fill material
should have erosion protection at all times.
8.
9.
Connect all roof drains to existing or future
storm system.
10.
Design and management of sub-surface drainage
system should be planner prior to construction and
imple~ented according to that plan. All water
should be conveyed to a safe, non-erosive outlet.
11.
All road designs should use availa~le soils
information."
14.
METRO:
No response.
NATURAL ENVIRONMENT:
1.
Topography: The site slopes downwards from the east to
the west. The grade is approximately 10-12\ in the
eastern area of the site, reducing to 2-5\ in the west-
ern half.
soils:' One type of surface soil is found on this site
per King County Soil Survey, 1973.
2.
a.
The entire site is classified AgC.
3.
AgÇ - 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: No mapped hydrographic features exist on
this site. The site lies within the lower Puget Sound
sub-basin of the Puget Sound drainage basin.
4.
Vegetation: This site is primarily covered with
pasture grasses. Very scattered evergreen trees and
brush occur in limited numbers.
5.
wildlife: Small birds and animals undoubtedly inhabit
this site: however, their population and species are
limited due to nearby development and the lack of
substantial vegetation on-site. No special or en-
dangered species are known to exist on or near the
property.
Mapped Sensitive Areas: The Sensitive Areas Map Folio
does not identify any Class III (severe) hazard areas
or map~ed wetlands as being present on this site.

~EIGHBORHOOD CHARACTERISTICS:
The property lies in the Federal Way area, approximately
1/4 mile northeast of the city of Tacoma. The immediate
vicinity of the proposal is fairly urbanized, with a few
large adjacent parcels in the process of development.
Immediately north of the site is the subdivision of Terhune
Addition, with lots sizes in the 7,200-square-foot range.
East of the site is the subdivision of Alde£dale Division 2,
which also has lot sizes of approximately 7,200 square feet.
Southeast of the site across 30th Ave. S.E. is the plat of
Grousepointe, currently under construction. Bordering the
eastern one-third of the proposal to the south is the pre-
liminarily approved plat of Grousepointe II, with 19 lots.
On the rest of the south border and on the west borders are
tracts ranging from 1 to 3 acres in size.
The site itself is vacant.
H.
GENERAL DESIGN:
1.
Internal Circulation: The internal roadway section
will be constructed to urban standards. The road will
extend directly west from one location on 30th Ave.
S.W. and terminate close to the western border of the
site with a temporary cul-de-sac.
Lot Pattern: The proposed lot and street layout will
be in conformance with King county codes and policies,
with the implementation of condition 13. The King
county Road Standards require 30 feet of width for a
half-street, which the applicant is proposing for this
project.
2.
I.
TRANSPORTATION PLANS:
1.
Traffic Generation: It is expected that approximately
120 vehicle trips per day will be ge~erated with full
development of the proposed division. This calculation
includes service vehicles (i.e. mail delivery, garbage
pick-up, school bus) which may currently serve this
neighborhood, work trips, shopping, etc.
Subdivision Access: Drivers leaving the project will
gain access to the main arterial system by proceeding
north on 30th Ave. s.w., turning right on 336th Way
S.W. and turning onto 21st Avenue Southwest.
2.
3.
Adequacy of Arterial Roads: This proposal has been
reviewed under both SEPA and the criteria in King
County Ordinances 7544 and 8052, Adequacy of Existing
Roadways and Intersections. The peak-hour traffic
generated by this subdivision falls below the threshold
requiring mitigation (ten peak-hour, peak-direction
trips). The existing arterial system will accommodate
the increased traffic volume generated by this
proposal.
Transportation Plans: The subject subdivision is not
in conflict with any King County transportation plan.
4.
J.
PUBLIC SERVICES:
1.
Schools: The subject subdivision will be served by
Brigadoon Elementary, Illahee Junior High, and Decatur
Senior High Schools. See Attachment 2 of this report
for comments received from the school district.

subject subdivision by means of a public sewer system
managed by the Federal Way Sewer and Water District. A
certificate of Sewer Availability, dated April 6, 1989,
indicates this sewer district's capability to serve the
proposed development (see Attachment 3). The Health
Department has recommended preliminary approval of this
proposed method of sewage disposal. The Building and
Land Development Division concurs with this
recommendation.
2.
Water Supply: The applicant proposes to serve the
subject subdivision with a public water supply and dis-
tribution system managed by the Federal Way Sewer and
Water District. A certificate of Water Availability,
dated April 14, 1989, indicates this district's capa-
bility to serve the proposed development. The Health
Department has recommended preliminary approval of this
proposed method of water supply. The Building and Land
Development Division concurs with the Health Depart-
ment's recommendation.
L.
COMPREHENSIVE AND COMMUNITY PLAN:

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 ~ainten-
ance of the entire pond. .. "
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 dis-
charge of stormwater into any sensitive area (e.g.
streams, wetlands, lakes, etc.). Such biofiltra-
tion includes 200 feet of broad, flat-bottom,
grass-lined swales) or equivalent systems.
Drainage outlets (stub-outs) shall be provided for
each individual lot, except for those lots
approved for infiltration by King County. Stub-
out shall be shown on the engineered plans and
shall conform to the following:
f.
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)

'responsible for coordinating the location of
all stub-out conveyance lines with respect to
the utilities (e.g. power, gas, telephone,
television) .
All individual stub-outs shall be privately
owned and maintained by the lot home owner.
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 log

PROPOSED PLAT OF GROUSEPOINTE III
FILE NO. S89POO62
taken at 6-foot minimum depth shall be submitted
by a professional engineer, or soil specialist.
This shall include, at a minimum, information ,on
soil texture, depth to seasonal high water ànd 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 permeability 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 approved for infiltration.
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,
capaci ty, overtopping" scouring, sloughing,
erosion or sedimentation of any drainage facility,
whether natural or man-made. Probable impacts due
to construction of the project must also be ad-
dressed 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.
1.
Current standard notes and ESC notes, as
established by BALD engineering review, shall be
placed on the engineered plans.
The following notes shall be provided on the map
page of the recorded document:
j.
"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 t on
file with the Department of Public Works. This
plan shall be submitted with the application of
any building permit. All connections of the
drains must be constructed and approved prior to
the final building inspection approval." Those
lots that are designated for "Individual lot
infiltration systems, the systems shall be con-
structed at the time of the building permit and
shall comply with plans on file at the Public
Works Record Center."
The following conditions specifically address drainage
issues for this particular plat:
