1. Adequate provisions are made for the public health, safety and general welfare-and for open spaces,
drainage ways, streets, alleys, other public ways, water supplies, sanitary wastes, parks, playgrounds
and schools.
Staff Comment
The proposed 18 lot preliminary plat includes provisions for storm water, access; watec, sewer,
recreation/open space, and schools. The proposed cul-de-sac road to the serve 15 of the 18 lots
meets the City of Aubum design standards for a local residential street. Three of lots will directly
access South 328th Street.
Page 4 of 10
Agenda Subject: Stipp's Meadow Preliminary Plat; PLT10-0007 Date: March 24, 2011
Water will be provided to the project through Lakehaven Utility District. The applicant provided a
water availability certificate as part of the application to showadequate water supply exists for the
project (Exhibit 10). Sewer is provided through the City of Auburn. ,
Adequate provisions are made for schools through the payment of school impact fees at the.time of
- building permit issuance. Sidewalks do not currently exist in the vicinity. Sidewalks will be provided
along South 328th Street the length of the subject property frontage as well as the cul-de-sac road
senring the project providing pedestrian access.
The proposed project of 18-lots does not reach the threshold of 50 units for requiring dedicated park
space as stated in ACC 17.14.100. However, the City assess a park impact fee at the building permit
stage of the project to address impacts to the City's park system by the project.
2: Conformance of the proposed subdivision to the general purposes of the comprehensive plan.
Staff Comment
Comprehensive Plan Elements
The following "section provides the text from the Comprehensive Plan and how PSE's project is in
conformance with the plan policies:
Land Use Goa17: Residential Development
To emphasize housing development at single family densities, in order to reestablish a mix of` .
housing types appropriate for a family ociented community, while recognizing the need and desire
for both lower density and higher density housing appropriafely located to meet the housing
needs of all members of the community.
Policy LU-17: Residential densities in areas designated for single family residential uses should
be no greater than 7 units per acre.
Objective 7.2: To designate land for the development of new single family homes.
Objective 7.3: To promote the development of quality single family neighborhoods which relate
the design and types of residential areas to importanf natural and manmade features.
Policy LU-26: Emphasis shall be placed upon the mannerin which the recreational needs of the
residents shall be met in the approval of any residential development.
Comment
The project site is 4.06 acres: With 18 lotsr proposed, this yields a density of 5 dwelling units per
net acre. Recreational needs of the residents are met through.the assessmenf of a park impact
fee at the building permit stage. The proposed project rneets the density of the R-5 zoning district
and land use designation of Single Family Residential and assists the City meeting its housing
targets and growth management objectives.
3. Conformance of the proposed subdiVision to the general purposes of any other applicable policies or
plans which have been adopted by the City Council.

The potential environmental impacts of the proposed subdivision are mitigated through the issued Mitigated Determination of Non-Significance. The City, issued an Adoption of an Existing
Environmental Document as part of this new preliminary plat.to address the addition of 4 lots to the .
project.
The proposed sewer extension is from the base of Mt. View Drive to the: unimproved right-of-way of
58'" Avenue South, then will head north to the Stipp's Meadow project and the continue north along
58' Avenue South to the Mt. View Estates project. Geotechnical analysis was provided for this utility
exfension as the construction is through steep slope and erosion prone area but within the existing
developed right-of-way of Mt. View Drive.
7. Adequate provisions are made so the preliminary plat will prevent or abate public nuisances.
, Staff Comment
Adequate provisions are made so the preliminary plat will prevent or abate public nuisances. The
vacant structures on site will be demolished.
'MODIFICATION OF STANDARDS=ACC CHAPTER 17:18
Pursuant to this chapter, modifications can be made to standards or specifications if the modification
- meets the requirements of ACC 17.18.030. . The applicant has requested the following modifications (Exhibit 9):
• Lot Orientation for Lots -16-18 to access from South 328th Street rather than the intemal plat road
• Modification from design standards for the slope of South 328'h Street exceeding 6% and for
intersection landing grade on South 328th Street and the proposed cul-de-sac road exceeding
5%.
Staff Comment
The request is to have Lots 16-18 access South 328t" Street rather than the internal plat road, which is
required by code to access the internal plat road, is a result of comments from the adjacent_residents
when the original preliminary plat was being processed. The residents wanted to have some of the new
homes face South 328th Street rather than only seeing the rear of homes. By having Lots 16-18 face
South 328th Street ~rovides a similar look to the existing neighborhood where the some of the homes
north of South 328t Street have direct access to the street rather than the internal cul-de-sac road.
Two modifications from the City's Design Standards were processed under the original preliminary plat
The City considers these plat modifications part of the new plat application as long as the ADA ramps in
the plat can meet the City and ADA standards. The applicant has provided some preliminary informafion
showing that the ADA requirements can be met however; staff has recommended a condition of approval
to address this item as part of the c,ivil reView.
The proposed plat modifications are necessary #o address the concerns raised by the neighborhood
during the original preliminary plat review and connect a new cul-de-sac road with the grade of the
existing road (South 328'h Street). DeVeloping the property in strict conformity with the provisions would
not allow reasonable and harmonious. use of the property. Allowing Lots 16-18 to access South 32e
Street develops these lots similar to the lots located north of South 328th Street. If#hese three lots were
to access the intemal plat road then potentially lots would be lost and not meet the density of the R-5
zone.
These modifications are not materially detrimental to the implementation of the policies and objectives of the comprehensive plan. The" modifications are to allow fhree lots access South 328t" Street rather than
the internal plat and allow the cul-de-sac road to be at a steeper grade than 6% as the cul-de-sac road is
connecting to an existing developed right-of-way that already exceeds 6% grade. If these modifications
Page 7 of 10
Agenda Subject: Stipp's Meadow Preliminary Plat; PLT10-0007 Date: March 24, 2011
were not permitted then potentially lots would be lost and not meet the density of the R-5 zohe in turn not
meeting the o6jectives of the comprehensive plan.
The modification requests do not lessen the requirements of the zoning ordinance and are consistent with
the purpose of the Land Adjustments and Divisions title.
NEIGHBORHOOD CIRCULATION PLAN ACC 17.16
The neighborhood circulation plan shall show the following:
a. Planned Street System. The planned street system must be compatible with the city's comprehensive
transportation plan. Development which is proposed in areas of the city which have a planned street
system which is a part of the comprehensive plan or the,city's six-year plan, and any other street
plan, shall make provisions for such streets and must not cause implementation of such street plans
to become unattainable.
b. Nonmotorized Transportation Routes. Preliminary plats and binding site plans which are proposed in
areas of the city which have planned routes or facilities for bicycles, equestrian, or other
nonmotorized transportation mode which is_a part of the comprehensive plan or the city's six-year -
plan, and any other street plan, shall make provisions for such routes and must not cause
implementation of such routes to become unattainable. -
c. A nonmotorized circulation system shall be integrated into the overall subdivision and surrounding
area.
i. When abutting vacant or underdeveloped land, new development shall provide the opportunity for
future connection to its interior pathway system through the use ofpathway stub-outs, building
configuration, and/or parking iot layout. The proposed location of future nonmotorized and
pedestrian connections shall be reViewed in conjunction with applicable development approval:
ii. Developments shall include an integrated nonmotorized circulation system that connects
buildings, open spaces, and parking areas with the adjaeent street sidewalk system.
iii. Pedestrian connections to existing or proposed trails/pedestrian routes on adjacent properties
shall be provided unless there are physical constraints such as sensitive areas that preclude the
construction of a pedestrian connection
" Staff Comment
" The planned street system is compatible with the City's Comprehensive Transportation Plan. 56th Avenue
South is a proposed bike route and there is existing right-of-way to accommodate a future bike lane
without right-of-way dedication. Frontage improvements are required along 56"' Avenue South;
however, the applicant applied for a street.delay request under the peevious plat application that was
granted (Recording Number 20090217000840). Granting this street delay request was prior to the City
_ adopting our updated Comprehensive Transportation Plan which includes the recently annexed area of
West Hill.
. As part of the project, frontage improvements are required along the subject property frontage. Sidewalks
will be constructed where sidewalks do nof exist today providing pedestrian access to 56th Avenue South:

Title of Document Being Adopted: Mitigated Determination ofNon-Significance Stipp's
Meadow Preliminary Plat.
Agency that Prepared -
Document Being Adopted: City of Aubum
Date Adopted Document Prepared: July 10, 2006
Description of Document
Being Adopted: A Mitigated Determination of Non-Significance was issued oh July 10,
2006 for a 14-lot subdivision including intemal public roads, sanitary sewers, water mains,
stormdrainage facility, and clearing and grading. The main access for the project is from
South 328t' Street. The storm drainage facilities will be constructed as part of the Stipp's
Meadow Preliminary Plat but also accommodate the stormdrainage from the Mt. View
Estates project (SEP06-0004 and PLT10-0008). The primary change from the project
analyzed uncler the MDNS being adopted is the addition of four single family lots. The
proposed intemal road layout remains the same, stormdrainage facilities will still be ,
consfructed as part of the Stipp's Meadow Preliminary Plat, and utility main (sewer, water,
and storm) construction remains unchanged.
When the project was proposed at 14-1ots, there were no off-site improvements required.
The addition of four single family lots will add four PM peak hour trips to the City's road
network. The City's transportation division determined that these additional four PM peak
hour trips do not trigger off-site improvements. The City assesses a traffic impact fee at
bu'ilding permit issuance which mitigafes traffic impacts associated with the project.

ENVIROWNAENTAL CHECKLIST
- Purpose of Check{ist:
The $tate Environmental Policy Act (SEPA), chapter 43.21 G RCW, requires all govemmental agencies
to consider the environmerrtal impacfs ofa proposal before making decisions. An environmental impact
sfatement (EIS) must be prepared for all proposals with probable significant adverse impacts on the
qual_ity of the environment. The purpose of this checklist'is to provide information to help you and the
agency identify impacts from your: proposal (and to reduce or avoid impacts from the proposal, if it can
be done) and to help the agency decide whether an EIS is required.
Insfructions for Applicants
Tliis environmental checklist asks you to describe some basic information. about your proposal.
Govemmental agencies use this checklist to determine whether the environmental impacts of your
proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the mosfi
precise information known, or give the best description you can.
You must answer each question accurately and carefully, to the best of your knowledge. In most cases,
you should be able to answer the questions from your own observations or projecf plans without the
need to hire experts. If you really do not know the answer, or if a question does not apply to your
proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid
unnecessary detays later.
Some questions ask about govemmental regulations, such as zoning, shoreline, and landmark
designations. Answer these questions if you can. If you have problems, the governmental agencies can
assist you.
The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of
time or on different parcels of land. Attach any add'i#ional information that will help describe your
proposal or its environmental effects. The agency to which you submit this checklist may ask you to
explain your answers. or provide additional information reasonabty related to determining if there may
be significant adverse impact.
Use of checklist for nonproject proposals:
Complete this checklist for nonproject proposals, even though questions may be answered "does
nof apply." tn addition, complete the Supplemental Sheet for Nonproject Actions (part D).
For nonproject actions, the references in the checklist to the words "project," "applicant," and "property
or site" should be read as "proposal," "proposec," and "affected geographic area," respectively.

Re: File NO. "PLT' 10-0007
To Whom It May Concern:
In response to your letter of 1Viarch 14; I respectfvlly ask my letter to be in file as non-support of
the proposal of 18 single family'resident homes for the following reasons;
1. Infrastructure of the West Hill of Auburn is inadequate to support more homes and
traffc. .
2. South 32e Street as well as the connecting roads of the West Hill Auburn area are site
limited; very few have rba.d shoulders and; were not desigiied for urban safe traffic.
3: The Auburn owned inter"sectionrof the West Va11ey Highwa.y is already docuinented to be
ina.dequate to handle the current traffic volume. _
4. The West Hill of Auburn has documented storm drainage problems that are not addressed
in this plot plan. "
5. The smaller lot sizes are not in conformity with the present West Hill standazds in which
there was perceived agreement to maintain.
6. The lack of access for emergency vehicles is inadequate and a safety issue that cannot be
ignored.
7. To alleviate traffic and safety issues, 56th Avenue South should be converted to a
41hrough" street.
Siricerely yours,
Thomas P 4Jones

RE: A Request for a Modification of Standards for Lot Orientation (16-18), Stipp's
`P+leadow Preliminary Plak Auburn, YVashingbon, 98001.
Dear Ms.. Chamberiain:
On behalf of the Stipp's Meadow, LLC, PK Enterprises is submitfing a request foc a modifcation of
standards to orient Lbts 16-18 to faee S. 3281th Street in the. Stipp's Meadow Preliminary Piat.
This request is based on public commer~ts that were made on the initiaily approved Stipp's
Meadow Piet., It was srated to the applicant thdt it would have been more appealing if some of
the lots faced them as opposed to looking at the rear fenoe: In doing so, the developmeint would
btend betber with the existing residences: The fvllowing commentary is justification to altow for
the modfication per Au6um Gty Code (ACC) Chapter 17.16: . . A. Such a modification is necessary because of speaai cireumstances related to the size,
shape, topography, location of surroundings of the suhject property, to provide the
owner with development rights and priviteges permitLed to other properties in the
vicinity and in the zoning district in which the subject property is located.
Response: The prnposed project borders on ifie svuffierly edge of 5. 328"" Steet wher,e there is an existing single=family cvmmunity. There are lots facing onto the
street and the neighbaring property ovvners feel our development would be better fit
iv indude lots faarrg thefrs We feel ihis is a special circumsiance in it►at the /ofs we
are re-orienting wlll allgn.wfth the exisdng lofs facing S. 328"' Sfreet. If the /ots
faced the other direcNon, a_ acess is required via a joint-use driveway, whfch is not an
Ideal sftuation for safefy and aaaess reasons In this instance, the request is baseci
on the surr+oundings of the srfbject properly and it helps the blending of our
deve%pmerrt with the existing subdivision.
B. That, because of such special circumstance.s, the development of the lot in strict
conformity inrith the provisions of this titte wili not altaw a reasonabte and harmonious
use of such lot.
Response: Again, the /ots being orierrted toward.s 5 3280 Sbeet are directly acuw
from eVs[ir►g residences cvrrent/y facing the s6eet. This modificatior► "b/ends" bhe
development with the exWng mmjnriniiy.

C. That the modificafion, if granted, wili not alter the charac6er of the neighborhood, or
6e detrimental to surrounding properties in which the lot is located.
Response: Thfs request wiU notalter the character of the existing community.
D. Such modfication will not be materiaily detrimentai to the implementation of the
poficies and objectives of the oomprehensive land use, transportation and uti'fity
comprehensive ptans of the city. .
Response: This request !s not cletrimental to d7e implementation of the policies and
.
objectives of any of the abovementloned plans wiffifn the city
Uterai interpretation of tthe provisions af this titfe wouid deprive the applicant of
rights commonly enjoyed lry other properties in the same zoning distiict.
Response: Again, this is in direct response to a suggesiion by tfie existing owners
- Maf face the project along S. 328a' Street when the property was originally p/attecl.
F, The approval of the modfication will be consistent with the purpose of this.
Response: This request is consistent with Me purpose of Me [itle and Me zoning
district. A new developmerrt should be harmonious and caexist with the existing
nelghtiofiood and that is the inient of this modification.
G. The modification, cannot lessen the requrrements of the zoning ordinanae. Arry such .
modfication must be processed as"a variance pursuarrt to ACC 18.70.010.
Response: This actfon does not lessen the requirements permitted by Me zoning district.
We appreuate your time and consideration in this matter. If there are any questions, please feel

RE: A Request for a Road Deviation for Road Gradient along South 328P
Street, Stipp's Meadow Plat, Aubum, Washingbon. (File No. PLT06-
0001/SEP06-0003)
Dear Mr. Dowdy:
On behalf of the Stipp's Meadow, LLC, PK Enterprises is requesting a Road Deviation for the road
gradient along South 328' Street which borders the Stipp's Meadow Plat The existing
constructed alignment is oonnected by another street (57t' Avenue South) and seve.rai
residences have direct access onto the road. The road gradient along the street follows the
existing topography which varies from 5 to 10 peroent (Note: Approximately 100 feet of the
road section west of the -intersecaon with 57"' Avenue South is 10 percent)
As discussed during several meetings with staff, the road alignment of South 328"' Stre.et is
sufficient to serve this project, as well as Mountain View Estates. Additional widening is required
to meet current city road standards. Concerning the road gradient, the proflle tracks the present
topography and is less than the maximum allowed for emergency use-which is 12 percent.
There are no sight distanoe issues along the road; thus, safety is not compromised for the
existing and/or future residents served by the road. Therefore, this deviation request is based
on the existing conditions along the road and will not be a detrimerrt or cause undo harm.
We appreciate your time and consideration in this matter. If there are any questions, please feei
free to contact me at (206) 227-7445.

Dear Mr. Kiizer
As requested, I have reviewed the laboratory test of the particle-size distribution performed on a soil sample taken by me from Test Pit 21 on March 12, 2007 (see attached Log
of Test Pit 21 and Particle-Size Analysis of Soils Figure 1, dated 4/5/07) to the laboratory _test
reports-on-samples you obfiained-this year: To compare the soil-samples, l-plotted the particle
size distribution of the 2007 sample to the particle size distribution of the samples you obtained
this year (see attached report of Particle-Size Analysis of Soils, dated 6/25/08, Figure 1).
" The CBR (Ca(ifornia Bearing Ratio) value of the soil sample from Test Pit 21 obtained on
March 12, 2007 was determined to be 28.3 (see,affached report of CBR of Lab Cornpacted
Soil). Based on the similarity of the particle size distribution of the most recent soil samples to
the 2007 sample it is likely that the CBR values of the recent samples will be similar fio the tested
CBR value of the 2007 sample. Therefore, I recommend that no further. CBR testing be
performed prior to construction. During construction, I recommend that the su6grade soils be
monitored and tested for parficle size distribution in order to determine where CBR testing is
warranted and where pavement secfion modifications are re PgCEIVIED

Subjectc Geologic Reconnaissance and
Slope Assessment of Sewer Alignmenfi
South 328thStreet to Mountain View Driv.e
Aabum Area, Washington
Dear Mr. Lee:
At your request, on December 13, 2006 a representative from our firm completed a
geologic reconnaissance and slope assessment of a.proposed sewer alignment
extending from the eastern end of South 328th Street down .to Mountain View Drive in
Auburn, Washington. Prior to: our site visit, a topographic map of the proposed the alignment had,been prepared and the alignment had been surveyed in S o fnld Wh s the
vegetation brushed out. The eastem end of the alignment`was, steeply P 9.
principal focus of'our site visit was to assess the slope conditions and offer possible
options for sewer line construction down the subject slope.
Project And Site Conditions
The projecf site was located on an upland plateau about',/, mile north of Peasley Canyon
and SR 18 in the northwestem part of Aubum, Washington (Figure 1). The proposed
alignment was about 1,500 feet in length ran in a west to east direction adjacent to the
Mountain View Cemetery to the south and.undeveloped land to the north. A six-foot tall
chain link fence ran along the north side of the Mountain View Cemetery separating it
from the proposed alignment.. Vegetation along the alignment consisted of dense
blackberries and other brush as well as medium srz_ed deciduous and evergreen trees.
An overgrown ditch abouf &feet wide was encountered between about 800 to 900 feet
east of South 328t'' Stceet,'where grayelly silty sand was exposed
The westem 1,240 feet of the alrgnment was gently sloPing down to the east at an
overall' gradient of about 5 percent. The eastemmost 270 fest of the alignment began
with a sharp break in slope at the toP of " a down to the east at an
rall adient of about 70_ per~cent, EI v s~ `~n~ nt ranged from about
oye gr
150 feet above sea level at the eastem entl of the, alignment to about 405 feet at the
westem edge at the end of South 328"' Streeifts@ddoW provided topographic map,

. 'I'RAFFIC IMPACT ANALYSIS
for two properties that make a combined
43-Lot Pair of Single Family Residential Plats
in the
West Hill Neighborhood
of the proposed annexation area to the
City of Auburn
Purpose
Briefly, the purgose of this study is to determine the horizon year traffic impacts that may
be anticipated with the completion of two close by properties that in combination will
total a new 43-lot pair of single-family residential plats; One residence already exists. The Nichols property is located on a site situated on the ea:st side of the future 58h'
Avenue S. about a block north of the easterly extension of South 328~' Street (yet to be
constructed) in the south-central part of King County on what may be called the City of
Aubum's west lull neighborhood that will be annexed to the City of Auburn. Similarly,
the Stipp projerty is loeated on a site situated on the southwest corner of the intersection
of South 328 Street and 5e Avenue S. (The actual cardinal direction on these street
names ma.y be revised on annexation to the City of Aubum to comply with the city's
adopted street name style.) More particularly, this traffic study is to obtain current traffic volume data at those
intersections impacted by 30 ormore site genera.ted p.in: peak how trips and to perForm a
corridor analysis to define the levels of service on the impacted;arterial corridors.
For assessing site related traffic impacts the forecast year of 2008 is used. This is the
horizon year when both sites axe expected to be fully occupied. This forecast yea.r is the
basis against which future impacts are to be measured. -

The locations of the two plats are shown on the Vicinitv M0, Figure 1, page 3. .
The trip generation data for the developments is based on the 7h edition of the T~
Generation Manuad published by the. Institute of Transportation Engineers (ITE). The
trip generation data is shown later in Table I ,
Typically, in developing residential neighborhoods such as these, the p.m. peak how has -
about twelve (12) percent higher traffic volumes than the morning peak hour. This is to
be expected since the,p.m. peak hour typically contains work, school, shopping and
social-recreation travel-demands as distinct to the morning peak hour that is primarily
work and school trip related. Accordingly, this traffic study reviews the p.m. peak hour
since it represents the worst case. This is also the city's standard requirement.
The inclusion of a background traffic growth rate for assessing horizon year volumes is in
accordance with the recommended practice of the Institute of Transportation Engineers
(ITE), Tra,~/'ic Access and Impact Studies for Site Development, Transportation
Engineering, August 1988. The growth rate used in.this study is taken at 3.5 percent per
year. This is the rate of growth typically recommended by the City of Auburn for its arterial street system.
Location and Access
For the purpose of this traffic analysis the location of the proposed plats considers the
following.
• The Stipp site with 15 proposed single-family residential lots to be located on the
south side South 328~' Street between 56t' and 57th Avenues S.
• The Nichols site with 28proposed single-family residential lots to be locaxed the
ea:st side of the future 58 Avenue S. about a block north of the intersection of South 328h Street (extended). -
For the purposes of this traffic analysis and consideiing 5Avenue S. does not yet exist
,but will be partially constructed for the Nichols site, it is assumed that all access will be
•via South 32e Street and thence to 56t' Avenue S.
56`b Avenue S:-in this residential neighborhood is the key route to South 316' Street
located to the north and South 331' Street loca.ted to the south. Both these east-west
facilities provide direct access to the regional highways including the Va11ey Freeway,
SR 167, via 15'' Street NW, and I-5 via South 32e Street and also to the adjacent ma.jor

shopping and recreational centers of Federal Way to the west and Auburn to the east.
In the immediate neighborhood all of the streets are county style, 2-1ane facilities with
posted speed limits of 35 mph. These roads are typically construeted with light
bituminous paving and do not include urban amenities-such as sidewalks, curb and .
gutters. The intersection of South 328 Street at 56'h Avenue S. has nighttime street
. lighting mounted on a timber utility pole. This intersection is located at.the crest of a
vertical curve. Entering sight distance (ESD) is partially constricted by vegetation to the
south. This can be readily improved by shrub removal.
The through status of 56t' Avenue S. is maintained with STOP sign control on a11
intersecting minor streets.
Scone
For the purposes of this traffic impact analysis the scope of the work considers a total of
43 new single-family residences of the combined Nichols and Stipp sites with initially a. single access to 56t' Avenue S. via South 324~' Place. The geometric design of this
intersection is essentially a two-lane by two-lane facility that will be constnicted to
adopted City of Auburn design standards.
Trip Generation
Trip generation for the proposed 43-1,ots of the combined Nichols & Stipp properties is
based on the 6h edition of the Institute of Transportation Engineers '(ITE) Ln ,
Generation Manual, for Land Ilse Code 210, the applicable reference for single-family
residential developments. As a significant combined deveTopment the published
regression equations are used.

Trin Distribution & Assionment
The new traffic generated by these two new residential developments will be distributed
. onto the adjacent roadway system and then onto the_regional transportation network The
traffic distribution and assignment of site-generated tiaffic is based on the AnaloQv
Method described in Transporfation and Land Development, Vergil G. Stover, 1988, -
published by the Institute of TransportationEngineers (ITE).
Considering ttie proposed combined developments the following p.m. peak hour traffic
assignment was defined.. -
• South 31e Street to and from the west @ 56h Avenue S. 12 trips
• South 316th Street to and from the east @ 56~' Avenue S. 13 trips
• South 331" Street to and from the west @ 56t' Avenue S. 8 trips
• South 331s' Street to and, from the east @ 56d' Avenue S. 17 trips
Since none of these arterial street corridors meets or exceeds the adopted city threshold
standard of 30 p.m. peak hour trips no corridor level of serve analysis is required.
At the key intersection serving the combined developments = 56~' Avenue S. at South
328'h Street the following p.m. peak hour assignment was defined.
e Westbound right tum 11 vehicles per how
• Westbound left turn 7 vehicles per hour
• Northbound right turn 18 vehicles per hour
• Southbound left turn 14 vehicles per hour
The total2-way p:m. peak hour traffic volume on 56th Avenue S. south of the South 32e
Street intersection is 25 vehicles per hour while to the north it is 25 vehicles per how. As
a result, neither the south leg of this corridor nor the north leg meets the city's adopted
level of service threshold for analysis.
Traffic Characteristics
Current p.m. peak hour traffic volume data were obtained in the field under typically
' early spring wea.ther conditions. The field data is depicted on Figure 2. _

Although data collection was essentially in the spring season, no significantly adverse
weather or unusual tra.ffic conditions existed that would skew or otherwise bias the data. Likewise, being in the spring season with a11 schools in session and normal employment
patterns extant, the data is considered entirely stable a.nd useful- for traffic ana.lysis
purposes. Current p.m. peak hour traffic volumes shown on the previous page are
schematic and do notimply any scale. As a traffic diagram the respective arrowheads '
note the direction of vehicular travel.
In general, currently, on the local arterial street network (school) bus and pedestria.n
traffic volumes were relatively light except near the elementary school on S. 316'' Street
in the mid-afternoon interval.
Assignment Diagram The p. m. peak hour assignment of tra,ff c from both developments is shown on Figure 3.
As with Figure 2 thus is a schematic diagram.
Canacitv Analysis
Capacity analysis is in accordance with the 1997 Highway Capacity Manuat (HCNl) _
and attendant intersection capacity up-d.a.tes for the new HCM 2000 publication by the
Transportation Research Boazd. The analysis was accomplished using the software
entitled HCS 3; produced by the McTrans Center at the University of Florida. It is used
under license to Christopher Brown, P.E. The results of the analysis are noted below in
Table II.
When reviewing the following LOS tabulated summaries, note that the computer input

In the level of service analysis Table II of page 7 note the analysis for the "with project"
, case is taken at the yea.r 2008 and assumes an average annual background growth rate of 3.5 percent per year for the next two years in accordance with City of Auburri adopted . "
. growth rate standards.
Corridor'Level of Service
Additionally, travel-time studies were performed over the peak hour. The average travel-
time for the 0.9 miles of the 56d' Avenue S. corridor from South 316'' Street to South .
331"` Street was recorded at 30.5 miles per hour. From the 2000 Highway Capacity
Mcmual, Table l 1-1, Arterial Levels of Service for Class II Arterials, Level of Service A
is described :as having a"free flow, speed" of over 30 mgh The travel time study
therefore indica.tes the current level of service is at the highest possible level. -
There are no reasons to suggest that this LOS `A' will not continue on completion of .
these two developments.
Left Turn Storage and Righf:Turn Lane Guidelines
The WSDOT Design Manual Figure 910-6, Guidelines for Left Turn StoraM were .
reviewed for applicability at the site's access via the intersection of South 328hStreet.
and 56~' Avenue S.
. With a total north-south p.m. peak fiour volume of 99 vph and a southbound left tum
voh,i g e of 18 vph, representing 18 percent, there are rio warrants for protected left turn
stora e on 56'h Avenue South. -
From Figure 910-11, and noting a northbound right turn volume of 23 vph and a peak
hour approach volume of 76 vph there are no warrants for a right turn lane or a right turn

• These two developments, comprising 43 new sirigle=family homes, will conform ,
to the existing neighborhood as it is currently developing.
• Based on the 74` edition of Traffic Generation the development will generate
some 478 trips per day with 40 of these trips taking place during the morning :
peak hour and 50 in the p.m. peak hour. ~ The background traffic growth is taken at 3.5 percent per year to the horizon year
of development - 2008.
~ The traffic assignment of site-generated traffc is based on the AnalogyMethod. • The City of Auburn's corridor analysis threshold is 30 p.m. peak hour site
generated trips.
• No arterial street corridor outside of 56t' Avenue S. is impacted by 30 or more
p.m. peak hour trips.
• From current travel-time studies on 560 Avenue S. from South 316" Street to
South 331" Street the level of service, describing the quality of traffic flow, was
found to be at the highest possible level.of service, LOS W.
• This level of service will not be altered by new site-generated traffic: it will
remain at LOS W.
• The site's key intersection at 56t' Avenue S. and South 32e Street will not
require left turn channelization for the southbound left tum movement nor
require any right turn lanes or pockets for the northbound right tum movement.
• At South 328t' Street a single approach lane will be sufficient for accommodating
the new site related traffic.
• The entering sight distance to the south from S; 32e Street should be improved
by removing the vegetation along the eastern street margin within the existing
right of way.
• The eexisting timber pole-mounted luminaire at ttie intersection of 56`h Avenue S.
and South 328t' Street is sufficient for nighttime'illumination. Additional street
lighting along South 32e Street if required will be associated with adopted City
of Auburn street standards, as applicable.

. . . Land.Use: 210 Single-Family Detachec! Housing
Description
Single-family detached housing Indudes all single-family detached homes on individual lots. A
typlcal site surveyed is a suburban subdivision.
Additional Data . .
The number of vehicles and resfdents ttave a high correlatfon witb average weekday vehlde trip
ends. The use of these vaciables is.limtted, however, because the numbers of vehldes and
resitlents was often diffieuft taobtain or predict. The number of dwelling units is generally used
as the independent variable of choice because it is -usually readily availabie, easy to projeCt and
has a hfgh coRelation with ayerage weekday vehide trip ends.
This land use lnduded data from a wide variety of units with different sizes, price ranges,
1oc.atiotis and ages. Conseqyenthr,-.there was a wide variagon in trips generated within this
catego ry. As expected, dwelling units that were larger ln size, more expensive, or farther away
. from the central bustness diWct`(CBD) had a higher rate of trip generatton per unit than those .
smaller in size, less expensive, or doser to the CBD. Other fadors, such as geographic locagon
and type of adjacent and neeirby development, may also have had an effect on the $ite trip
generation. -
Sing(e-family detached units had the highest trip generation rate per dwelling unit af all residentlal
uses, because they were the:la_rgest.units in slze and.had more residents and more vehides per
unit than other restdentfal Iand uses; they were generally Iocated farther away from shopping
centers, enaptoy.ment areas -and other trip attractors_ than other residential land uses; and they
generaily had fewer altemate modes of transportaflon ava(latile, because they were typicaily not
as concentrated as other reslidentlai land uses.
The peak hour of the:generator typically coincided with the peak hour of tMe adjacent street traffrc.
The sites were surveyetl from the late 1960s to the 2000s throughout the United States and
Canada.

Supplemental Analysis
AM. Peak Hour @ 5 1 " Avenue S. and 5..3166 Street .
Per King County request via Elizabeth Chamberlain Memo of 6/20/06
Dear Mr. Kitzes: The Gity of Auburn's e-mail memorandum concerning the referenced plats and the
subject intersection has been noted. The following is submitted in answer to that concern
by King County.
First, the a,m. peak hour traffic volumes at the intersection of 51 Avenue S. and S. 316" .
. Street were obtained this morning. The raw field data is attached for reference.
Second, with a 3.5 percent background growth pursuant to the City of Auburn's standard
ha.s been used to define the year 2008 a.m. peak hour forecast. A schematic diagram of
tbis is also attached. '
With the trip distribution used' in the Ma.y 15t' 2006 submittal to the City of Auburn the
morning peak hour assignment was derived. This is shown on the atta.ched schematic
diagram.
With the 2008 foreca.st and the morning peak hour assignment the horizon year data with
-the project completed was derived.
The total a.m. peak hour traffic volume generated by the site is 40 vehicle trips per hour.
The site's traffic through the subject intersection is 12 trips per how. This represents a
rate of (12/40) thirty (30) percent and, as such, is within tfie 20 percent threshold noted in
the Charnberlain Memo. Of course, at 12 site-generated a.m. peak hour trips it is 'less than the 30-trip peak hour
standard noted in the Chamberlain Memo.
Trafric Engineers Cn Transportation Planners
Mr. Phillip Kitzes .
, . . 7une 22nd, 2006 ,
Page 2
The moming peak hour level of service (LOS) was computed for.the three following
standard scenai-ios using currettt geometrics and the current control device strategy, to
wit, STOP sign on S. 316'' Street. ;
1. Current a.m. peak hour LOS . 2. 2008 LOS without project
. 3. 2008 I;OS with project
The three LOS analyses for these three scenarios are attached for reference following the
traffic diagrams. .
„ . The results of the analysis show the following.
• Current a.m. peak hour LOS =.C with a delay of 21.9 seconds
m 2008 LOS without project =,I) with a delay of 25.6 seconds .
0 2008 LOS with project = D with a delay of 27.1 seconds
Since the LOS is well within the adopted county standard no mitigation is required and
none is recommended. •
If you have any .questions, please feel free to call at your-convenience. , Yours tnzly,
