Except as modified below, the facts set forth in the KIng
County Building and Land Development Division's
preliminary Report to the Zoning and Subdivision Examiner
for the March 17, 1988 public hearing are found to be
correct and are incorporated herein by this reference.
Copies of the said report will be attached to the copies
of this report submitted to the County Council.
),
Issues were raised by correspondence directed to the
Building and Land Development Division concerning the
adequacy of the roads north of the subject property to
safely accommodate additional traffic without increased
congestion. Roads to the north (primanly 13th Avenue
S.W. and 14th Avenue S.W., between S.W. 312th Street and
S.W. 316th Streetl, are local access streets without
sidewalks. These streets now serve the residential area
and Lakota 'Junior IJigh school, located between the subject
property and S.W. Jl2th Street.
At the March 17,1988 public hearing, the Examiner
requested that additional information be furnished
concerning the existing and anticipated volume of traffic
on the roads north of the subject property, their existing
condition and analysis of their safety for vehicles and
pedestrians.
The evidence provIded when the ~'UbliC hearing was reopened
on March 31, 1988 was that the proposed subdivision will
not adversely impact the conditions surrounding the
school, but will provide some relief of existing
congestion by providing an alternative route to the
south. Information provided by the King county Department
of Public Works', Division of Traffic and planning, was
that more trips would be generated southbound then
northbound. In their opinion, the congestion which
presently exists should be addressed by the Department of
Public Works and the school district, as it is not a
condition which would be adversely impacted by the
proposed plat of Lakota Trails. Similar evidence and
conclusions, were provided by the applicant's traffic
consultant. Existing and projected average daily vehicle
traffic counts for the area indicate present and
anticipated levels of service which exceed the minimum
requirements of the King County Arterial Road Adequacy
Ordinance.

Construction of 13th Avenue S.W./S.W. 3J7th Street/15th
Avenue S.W. through the subject property will provide an
additional north-south collector street serving the area
between S.W. 312th Street and S.W. 320th Street. A
neighborhood collector street requires a 56 foo< wide
right-of-way. It normally functions <0 connect two or
more neighborhoods and provide a connecting route to
arterials. King County Road Standards call for a some'.hat
restricted access, with lots to front on local access
streets where feasible. See King County Road Standards,
Section 2.0J, page 10. D;Sign speed is 35 miles per hour.
Due to the existence of extensive wetlands on this
property, there is a subStantial constraint on providing
local access street or cul-de-sac accesses to the lots
which front on the neighborhood collector. However, i<
may be possible, when road plans and profiles are
submitted, to provide additional "eyebrow. access areas.
To the extent that it is feasible <0 do so, such areas
would reduce the number of individual access driveways
directly intersecting the neighborhood collector street.

The preponderance of the evidence is that the proposed
development will 'not have adverse impacts upoo traffic
congestion or the safety of pedestrian and vehicular
traffic in the area lying between the subject property and
S.W. 312th Street. ThIs conclusion is based upon the
uncontroverted expert testimony that the proposed
development will provide an alternative route to the
affected area which will more likely reduce traffic volume
at the intersection of 14th Avenue S.W. and S.W. 312th
Street than increase it. In the event the projections and
analysis of impacts proves incorrect, the primary
responsibility for resolving congestion and safety
concerns that exist in the area is that of the Kin9 County
Department of Public Works, rather than the proponent of
this development.

Prior to road and drainage plan approval, the
applicant may join into an opportunistic
agreement with King County Surface Water
Management Division, King County Building and
Land Development Division, and others in
developing Lower puget Sound Wetland No.9 into a
regional detention facility. The final road and
drainage plans shall reflect the terms of the
agreement. The regional facility shall be
constructed and functional prior to final
recording of the subdivision (KCC 9.104.090.CI.
b.
If the agreement described above cannot be made
or fulfilled, the final road and drainage plans
shall reflect the standard King County detention
requirements for subdivisions. Since thè revised
plat received Pebruary 16, 19B8 does not show
individual tracts for detention, applying the
standard subdivision detention requirements may
result in a reduction in the total number of lots
within the subdivision.
c,
If Lower Puget Sound Wetland No.9 is not
established as a regional detention facility
prior to the recording of this plat, the
individual tract or tracts provided for detention
of storm water from the subject property may be
identified as temporary detention tract(sl, so
that their ownership and availability for
residential lot development could revert to the
property owner at such time as a regional
detention facility is e-stablished utilizing the
said wetland, in a manner which adequately serves
the retention/detention requirements for the
subject property. Details shall be worked out
with the Subdivision Technical Committee.
If the storm water runoff is to be controlled by standard
on-site subdivision facilities, and not by a regional
facility, then no retention/detentionfacility shall be
located within any stream, wetland, or natural drainage
feature, unless approved by the King County wetland
specialist and the drainage review engineer.
Two inventoried wetlands (Lower puget Sound Wetland No, 9
and No. 211 and one uninventoried wetland are locat.d
within the propose" subdivision. To protect the wetlands

Standard Storm Drainage Requirements (Portion Only)
BALD a'Pproval of the drainage and roadway plans is
required prior to any conStruction.
A separate ESe plao 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 sequencel.
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 15-foot access
roadway to all manholes (R/D). Access must also be
provided for maintenance of the entire pond,
Prior to reèording 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,
Oil/water separation facilities shall be provided at each
point of permaoent 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.
Drainage outlets (stub-outs I shall be provided for each
individual lot, except for ,hose lots approved for
infiltration by King County. Stub-outs shall be shown on
the engineered plans and shall conform to the following:
1.
I
Each outlet shall be suitably located at the lowes<
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 shali be located with a
five-foot-high, 2' x 4' s<a'ke marked 'storm' or
'drain'. The Stub-out shall eXtend above surface
level, be visible and be secured to the stake.
J.
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.
DrOlnage easementS are requlCed for drainage sYStems
designed to convey flows ,hrough individual lots.
5.
The developer and/or contractor is responsible for
coordinating the location of all stub-out conveyance
lines with respect to the utilities (e.g., power, gas,
telephone, ce1evision).
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 süiLãbility 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
soil 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 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 withio 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 eogineering review, shall be placed on the engineered
plans,
j,
The followiog ootes shall be provided 00 the map page of
the recorded document:
1.
For all lots:
2.
.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'"lon the approved
conStruction drawings I' on file with the
Department of Public Works. The plan 'or these
connections shall be subm1<ted w1th the applicat'on
for aoy building permit. All connections of the
drains muse be conStructed and approved prior to the
final buil~ing inspection approval.'
Por any lots approved for ,nd,vidual infiltration:
'Individual lOt infiltra"on syseems shall be
constructed at the time the residence is constructed
and shall comply with plans on file at the Public
Works Record Center.'
