ENVIRONMENTAL CHECKLIST
PURPOSE OF CHECKLIST
The State Environmental Policy Act (SEPA), RCW Chapter 43.21 C, requires all governmental agencies to
consider the environmental impacts of a proposal before making decisions. An environmental impact
statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality 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.
INSTRUCTIONS FOR APPLICANTS
This environmental checklist asks you to describe some basic information about your proposal.
Governmental 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 most 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 project 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 delays later.
Some questions ask about governmental 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 additional 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 reasonably related to determining if there may be significant adverse impact.
USE OF CHECKLIST FOR NON -PROJECT PROPOSALS
Complete this checklist for non -project proposals, even though questions may be answered "does not apply."
In addition, complete the Supplemental Sheet for Non -Project Actions (part D).
For non -project actions, the references in the checklist to the words "project," "applicant," and "property or
site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

4. Date checklist prepared:
March 2012
Agency requesting checklist:
City of Federal Way, Planning Division
Proposed timing or schedule (including phasing, if applicable):
The project is currently in design phase, construction phase is planned for Summer/Fall 2012.
7. Do you have any plans for future additions, expansion, or further activity related to or connected with
this proposal? If yes, explain.
This SEPA checklist is for the cityfunded portion of the project along the south side of 312"' Street
e-xtendingfrom 1 e' Avenue to SR 509. Work is being conducted under a separate contract, for the
north side of 312"' Street and is called the Lakota Middle School Safe Routes to School Project. The
Lakota Middle School Safe Routes to School Project is federally funded. The WSDOT Local Programs
Engineer determined the two projects are independent, meaning the north portion has logical termini
and independent utility from the improvements on the south side of the roadway. Hence the separate
SEPA reviews do not constitute segmenting the project.
8. List any environmental information you know about that has been prepared, or will be prepared,
directly related to this proposal.
The engineering team has prepared a Technical Information Report (TIR), Stormwater technical memo,
and a geotechnical report.
9. Do you know whether applications are pending for governmental approvals of other proposals directly
affecting the property covered by your proposal? If yes, explain.
None are known.
10. List any government approvals or permits that will be needed for your proposal, if known.

11. Give a brief, complete description of your proposal, including the proposed uses and the size of the
project and site. There are several questions later in this checklist that ask you to describe certain
aspects of your proposal. You do not need to repeat those answers on this page.
The purpose of the SW 312t1i Street —14'' Avenue SW to SR 509 - Street Improvements Project is to
provide safety improvements, including replacement of the existing traffic signal at SW 312`�' and SR
509; new left hand turn lanes on the east and west leg of the SW 312''' and SR 509 intersection; a
continuous left turn lane along SW 312"' between SR 509 and 14''' Avenue SW; bike lanes, curb
gutter, sidewalks, and planter strip on the south side of SW 312''' extending from approximately 200
ft west of SR 509 to approximately 400 ft east of 141'' Avenue SW.
New channelization will require the curb along the south side of the ARCO site (at the intersection
of SR 509 and SW 312`" Street) to be moved one foot north to accommodate the new channelization
on the east leg of the intersection. The ARCO driveway will be reconstructed to match the
channelization, reducing the planter strip but not reducing the 5 ft walkway.
The west portion of SR 509 intersection will be widened into the existing right of way to provide the
12-ft turn lane, a 4 ft planter strip, and 6 ft sidewalk.
12. Location of the proposal. Give sufficient information for a person to understand the precise location of
your proposed project, including a street address if any, and section, township, and range if known. If a
proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal
description, site plan, vicinity map, and topographic map, if reasonably available. While you should
submit any plans required by the agency, you are not required to duplicate maps or detailed plans
submitted with any permit applications related to this checklist.
Project site is located in King County, within the City of Federal Way, along SW 312"' Street.
Access is from SR 509. NW 1/, Section 7 Township 21NRange 04EI NE 114, Section 12 Township
21NRange 03E
B. EWIRDNMENTAL ELEMENTS
EARTH
a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other.
b. What is the steepest slope on the site (approximate percent slope)?
Site is somewhatflat with a downward slope movingfrom east to west; the project site has
approximately a 6% to 7% slope.
c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, mulch)? If
you know the classification of agricultural soils, specify them and note any prime farmland.
According to the geologic map, near -surface deposits in the project area consist primarily of
glacial till. Deposits mapped as "till" typically consists of a dense to very dense, unsorted
mixture of boulders, cobbles, gravel, and sand in a matrix of silt and clay with some lenses of
poorly sorted to sorted, stratified sand and gravel. The glacial till unit typically exhibits low to
very low permeability and high shear strength characteristics resulting from compaction by the
weight of the overlying glacier. See Geotechnical Report.
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe.
Bulletin #050 — August 19, 2004 Page 3 of 12 k:\Handouts\Environmental Checklist
The site is somewhat flat underlain by compacted soils and there is no known history of landslides
or unstable soils within the immediate project area. Additionally the City of Federal Way Critical
Area Map does not show the project area as being within a landslide hazard area or within an
erosion hazard area.
e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate
source of fill.
It is anticipated that 350 cy of importfill will be required and 1,900 cy of existing material will be
removed for the safety improvements. Most of thefilling would be in the vicinity of the southeast
corner of the SW 317th Street and SR 509 intersection. All material reproved will either be
recycled on site if appropriate or removed and disposed of at a landfill.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.
The site is somewhat flat and all work will comply with applicable erosion control regulations.
g. About what percent of the site will be covered with impervious surfaces after project construction
(for example, asphalt or buildings)?
It is anticipated the project will add up to 7, 000 square feet of additional impervious surface.
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any.
All applicable erosion control measures will be complied with during construction activities.
The planting buffer between the sidewalk and road will contain a mix of low shrubs, groundcover
and hydroseed will be used after constructions preventing erosion from exposed ground.
Appropriate drought tolerant plantings will be used.
2. AIR
a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors,
industrial wood smoke, etc.) during construction and when the project is completed? If any,
generally describe and give approximate quantities if known.
Minor dust emissions could occur during construction activities. The project adds safety
improvements and does not add roadway capacity and therefore will not increase existing vehicle
emission levels.
b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally
describe.
None known.
c. Proposed measures to reduce or control emissions or other impacts to air, if any.
If needed, the site will be sprayed with water during construction activities during dry periods to
reduce dust particle emissions.
3. WATER
a. Surface
Bulletin #050 — August 19, 2004 Page 4 of 12 k:\Handouts\Environmental Checklist
1) Is there any surface water body on or in the immediate vicinity of the site (including year-
round and seasonal streams, saltwater, lakes, ponds, and wetlands)? If yes, describe type and
provide names. If appropriate, state what stream or river it flows into.
A small tributary of Lakota Creek is the closest water feature and it is approximately 100 feet
away from the project area. According to information on the WDFW salmon scape web site
(accessed February 2012) Lakota Creek and its tributary are non -fish bearing.
2) Will the project require any work over, in, or adjacent to (within 200 feet) the described
waters? If yes, please describe and attach available plans.
No in -water work will occur as part of the SW 312"'/SR 509 project.
3) Estimate the amount of fill and dredge material that would be placed in or removed from
surface water or wetlands and indicate the area of the site that would be affected. Indicate the
source of fill material.
None, since no in -water work will occur.
4) Will the proposal require surface water withdrawals or diversions? Give general description,
purpose, and approximate quantities if known.
No surface water withdrawals or diversions will occur.
5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan.
Area is not in a floodplain, per FEMA map 53033C1250Fpanel 1250 of 1725 the area is
zone X, areas of minimal flooding and outside of the floodplain.
6) Does the proposal involve any discharges of waste materials to surface waters? If so,
describe the type of waste and anticipated volume of discharge.
No waste material will be discharged into surface waters. All stormwater will be treated
prior to discharging into the existing Federal Way stormwater system.
b. Ground
1) Will ground water be withdrawn, or will water be discharged togroundwater? Give general
description, purpose, and approximate quantities if known.
No groundwater will be withdrawn and water will not be discharged to groundwater. All
stormwater will go into the existing City of Federal Way stormwater system.
2) Describe waste material that will be discharged into the ground from septic tanks or other
sources, if any (for example: Domestic sewage; industrial, containing the following
chemicals...; agricultural; etc.). Describe the general size of the system, the number of such
systems, the number of houses to be served (if applicable), or the number of animals or
humans the system(s) are expected to serve.
None.
c. Water Runoff (including stormwater)
Bulletin #050 — August 19, 2004 Page 5 of 12 k:\Handouts\Environmental Checklist
1) Describe the source of runoff (including stormwater) and method of collection and disposal,
if any (include quantities, if known). Where will this water flow? Will this water flow into
other waters? If so, describe.
Per the stormwater design in the Basis of Design Report, the SW 31 y h Street —14"' Avenue
SW to SR 509Street Improvements Project includes constructing a new storm sewer main
and providing water quality system for the catchment area. Stormwater sources will include
the new pavement areas and currently the sidewalks are planned to be constructed of
pervious pavement. All pollution generating impervious surfaces (PGIS) will be conveyed to
water quality treatment facilities. The treated water will flow into the existing City storm
system and treated water conveyed into Lakota Creek.
2) Could waste materials enter ground or surface waters? If so, generally describe.
No, all storm water will be treated prior to flowing into the Cities existing storm water
conveyance system.
d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any.
All stormwater will be treated prior to flowing into the Cities existing storm water conveyance
system. Additionally the new sidewalks are planned to be pervious concrete, and sidewalks are
considered a Non Pollution Generating Surface.
4. PLANTS
a. Check or circle types of vegetation found on the site.
X deciduous tree: alder, maple, aspen, other
X evergreen tree: fir, cedar, pine, other
X shrubs
X grass
pasture
crop or grain
_ wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other
_ water plant: water lily, eelgrass, milfoil, other
_other types of vegetation
b. What kind and amount of vegetation will be removed or altered?
The site is developed with ornamental landscaping, trees and lawn. Due to the widening needed
for safety improvements(sidewalks and bike lanes), there will be some additional right of way
required that will impact the existing grass, shrubs and trees in the project area.
c. List threatened or endangered species known to be on or near the site.
No known listed plant species are on or near the project site per the DNR Natural Heritage Data
base.
d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on
the site, if any.
Site will provide a landscaped buffer separating the sidewalk and traffic. Appropriate drought
tolerant plantings will be provided.
Bulletin #050 — August 19, 2004 Page 6 of 12 k:\Handouts\Environmental Checklist
5. ANIMALS
a. Circle any birds and animals that have been observed on or near the site or are known to be on or
near the site.
birds: hawk, heron, eaggle, songbirds, other:
mammals: deer, bear, elk, beaver, other:
fish: bass, salmon, trout, herring, shellfish, other:
b. List any threatened or endangered species known to be on or near the site.
The site is in a developed area of the city and over 134 ft away from Lakota Creek, a non -fish
bearing stream and over 5,184 ft away from Dumas Bay, Puget Sound. The State Fish and Wildlife
public Priority Habitat and Species Report shows there are no listed species within the project
area.
c. Is the site part of a migration route? If so, explain.
Much of Western Washington is located in the Pacific Flyway, a bird migration corridor.
d. Proposed measures to preserve or enhance wildlife, if any.
The site is in a developed area, will not impact existing areas of open space, and no measures to
enhance wildlife habitat adjacent to the roadway is proposed.
6. ENERGY AND NATURAL RESOURCES
a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed
project's energy needs? Describe whether it will be used for heating, manufacturing, etc.
Electrical energy will be required for powering the additional street lighting and the new signal
and cross walk
b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally
describe.
No. The at -grade construction of the roadway should not impact the potential use ofsolar energy
by adjacent properties.
c. What kinds of energy conservation features are included in the plans of this proposal? List other
proposed measures to reduce or control energy impacts, if any.
None are planned.
7. ENVIRONMENTAL HEALTH
a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and
explosion, spill, or hazardous waste that could occur as a result of this proposal? If so, describe.
A phase 1 corridor level study has been conducted for the SW 312"'/SR 509 project. The shopping
center west of SR 509 and north of SW 312d' appears to have potential recognized environmental
conditions due to past releases into the groundwater from a former dry cleaning site and two gas
stations. Borings conducted in the project vicinity did not encounter groundwater within 20 feet.
Since the ground disturbance west of SR 509 and on the south side of SPV 312"' will be
Bulletin #050 — August 19, 2004 Page 7 of 12 k:\Handouts\Environmental Checklist
approximately 3 feet deep, it is not anticipated that exposure to environmental health hazards will
occur from this work.
1) Describe special emergency services that might be required.
No special emergency services are anticipated for the project.
2) Proposed measures to reduce or control environmental health hazards, if any.
In addition to have a construction Temporary Erosion and Sediment Control Plan a spill
control plan will be in place during construction activities.
b. Noise
1) What types of noise exist in the area that may affect your project (for example: traffic,
equipment operation, other)?
The existing noise sources in the area should not affect the project.
2) What types and levels of noise would be created by or associated with the project on a short-
term or long-term basis (for example: traffic, construction operation, other)? Indicate what
hours noise would come from the site.
Project construction will have short-term temporary noise impacts. The project does not

EXECUTIVE SUMMARY
The City of Federal Way (City) is proposing roadway and sidewalk improvements along SW
312'h Street from 14`' Avenue SW to State Route (SR) 509. The project area is located along SW 312th
Street between SR 509 and 14t' Avenue SW in the City of Federal Way, Washington, within the
Puyallup/White watershed [Water Resource Inventory Area (WRIA) 10] in Section 7, Township 21N,
Range 04 E. The planned roadway improvement project will widen SW 312t` Street from the south of the
centerline starting approximately 200 feet (ft) west of the intersection with SR 509 and ending at the west
side of the intersection with 14th Avenue SW. A new signal and left turn lanes will be built at the SR 509
intersection. Curb, gutter, sidewalk and planters will be constructed connecting the new sidewalk to the
existing sidewalk near the SW 312fl' Street/SR 509 intersection. This proposed project also includes
illumination, drainage improvements, and necessary utility adjustments
Wetlands, waterways, and/or their buffers can fall under the jurisdiction of the U.S. Army Corps
of Engineers (USACE) under Section 404 of the Clean Water Act, the Washington State Department of
Ecology (Ecology) under the State Water Pollution Control Act, and the City under the Critical Areas
regulations of the Municipal Code.
This report presents the results of the wetland and critical area investigation conducted for Tetra
Tech and the City of Federal Way (City) for the proposed project.
The investigation did not identify any wetlands within the study area. Lakota Creek, a non -fish
bearing stream with a 50 ft setback area, was identified in the western end of the study area approximately
100 ft from the project area. Based on the observed and documented onsite conditions within the study
area there are no wetlands, streams, or associated buffers/setbacks within the project area.

1.0 INTRODUCTION
The City of Federal Way (City) is proposing roadway and sidewalk improvements along SW
312t' Street from 10 Avenue SW to State Route (SR) 509 (Figure 1). The purpose of the project is to
improve pedestrian movement and safety along the south side of SW 3120' Street from approximately
200 feet (ft) to the west of SR 509 to the west side of the intersection at 14`h Avenue SW, in Federal Way,
King County, Washington.
The planned roadway improvement project will widen SW 312t' Street from the south of the
centerline starting approximately 200 ft west of the intersection with SR 509 and ending at the west side
of the intersection with 14th Avenue SW. A new signal and left turn lanes will be built at the SR 509
intersection. Curb, gutter, sidewalk, and planters will be constructed connecting the new sidewalk to the
existing sidewalk near the SW 312'h Street/SR 509 intersection. This proposed project also includes
illumination, drainage improvements, and necessary utility adjustments Landau Associates, under
contract to Tetra Tech, conducted this investigation to assist the City in determining potential impacts to
wetlands and other "waters of the U.S, and other critical areas regulated by the City. The results of
Landau Associates' investigation are presented in this report, which did not identify any wetlands,
waterways, or associated setbacks/buffers within the project area. One waterway, Lakota Creek, and an
associated setback were identified within the study area, but outside of the project area limits.
1.1 SITE DESCRIPTION
The project area is located along SW 312`s Street between SR 509 and 14`h Avenue SW in the
City of Federal Way, Washington, within the Puyallup/White watershed [Water Resource Inventory Area
(WRIA) 10] in Section 7, Township 21N, Range 04 E. The study area includes a 200 ft radius
surrounding the project area boundary (Figure 2).
Existing land uses within the study area are primarily commercial and residential. The north side
of SW 312`h Street (from east to west) is residential housing and the Dash Point Village Shopping Center.
The south side of SW 312`h Street (from east to west) is a fire department, Lakota Park and undeveloped
property. Lakota Creek flows southeast to northwest through private property at the western edge of the
study area.
1.2 REGULATORY BACKGROUND
The Clean Water Act (CWA) requires authorization for the discharge of dredged or fill material
into the "waters of the U.S." under Section 404. The Federal Way Revised Code (FWRC) contains
requirements for establishing wetland buffer widths, stream setbacks, and building setbacks for any
3/28/12 YA1187\003.020\R\Wetland Investigation\Rnal Wetland Report_City.docx LANDAU AssocIATES
1-1
alteration, including fill, of wetlands, streams and their buffers/setbacks. The Washington State
Department of Ecology (Ecology) requires compliance with the State Water Pollution Control Act (RCW
90.48), and it has administrative oversight of Section 401 of the CWA for water quality certification in
the case of impacts to U.S. Army Corps of Engineers (USACE) jurisdictional "waters of the U.S." Any
work that will use, divert, obstruct, or change the bed or now of state waters, including streams and
rivers, must obtain Hydraulic Project Approval (HPA) issued by the Washington Department of Fish and
Wildlife (WDFW). Washington Department of Fish and Wildlife HPA is administered under RCW 77.55
and rules in WAC 220-110. Wetlands and certain waterways are regulated by federal, state, and local
governmental agencies and compliance with one agency does not necessarily fulfill permitting
requirements of any other agencies.

2.0 METHODS
Landau Associates conducted the wetland/waterway investigation in accordance with the USACE
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains,
Valleys, and Coast Region (USACE 2010) and Ecology's Determining The Ordinary High Water Mark
on Streams in Washington State (Olson and Stockdale 2010).
Chapter 19.175.010 FWRC specifies use of the Ecology Washington State Wetlands
Identification and Delineation Manual (Ecology 1997). However, as of March 1, 2011, Ecology has
adopted USACE's Regional Supplement for wetland investigations in accordance with WAC 173-22-035.
Therefore, Ecology's Washington State Wetlands Identification and Delineation Manual (Ecology 1997)
was not applied.
In general, the USACE recommends gathering preliminary data and synthesizing available
background information, followed by a field investigation. Field investigation was limited to accessible
areas along the proposed roadway alignment.
2.1 BACKGROUND INFORMATION REVIEW
Landau Associates reviewed the following public domain resources to determine existing
conditions and potential wetlands and other "waters of the U.S." within the study area:
• Topographic map [image data source: U.S. Geographic Services (USGS)]
■ Aerial photograph (image data source: ESRI World Imagery)
• National Wetlands Inventory (NWI) map [Image data source: U.S. Fish and Wildlife Services
(USFWS), 2010]
• Federal Emergency Management Agency (FEMA) GIS data Flood Map (image data source:
FEMA, 2011)
• USDA National Resources Conservation Service (NRCS) Web Soil Survey (image data
source: USDA 2006)
• National Hydric Soils List (USDA, NRCS website 2010)
• City of Federal Way Critical Areas Map (Federal Way 2008)
• Precipitation data [USDA NRCS website 2002, National Climatic Data Center, (NCDC)
2011]
• WDFW web resources: Priority Habitat and Species (PHS) on the web (WDFW 2012a) and
SalmonScape mapping (WDFW 2012b).
2.2 WETLAND INVESTIGATION
The USACE outlines a three -parameter approach to determine the presence or absence of
wetlands that requires evaluating vegetation, soil, and hydrology (Table 1). Landau Associates' biologists
3/28/12 YA118A003.020\R\Wetland Investigation\Final Wetland Report_City.docx LANDAU ASSOCIATES
2-1
completed the field investigation using the routine onsite method, where data are collected at locations
representative of typical wetlands and/or uplands of the study area. Following this method, an area is
determined to be wetland if each of the following three criteria are met (also see Table 1):
■ The dominant vegetation is hydrophytic
■ Soils are hydric
• Wetland hydrology is present.
"Difficult wetland situations" may occur in which one or more of the required criteria have been
disturbed by human or natural events (atypical situations) or are absent due to natural variability (problem
area). In cases of difficult wetland situations, a wetland determination can be based on the best available
information of the site, knowledge of the ecology of wetlands in the region, and/or the other undisturbed/
present criteria.
2.3 WATERWAY INVESTIGATION
The ordinary high water mark (OHWM) of waterways was identified in accordance with
methodology developed by Ecology (Olson and Stockdale 2010). The OHWM identification was based
on site observations. The methodology focuses on examining existing hydrologic data and observation of
field indicators including hydrology, soils and sediments, vegetation, and marks of scouring, etc. Stream
typing and setback widths are based on Chapters 15.05.030 and 19.165.010 FWRC.

3.0 RESULTS
3.1 BACKGROUND INFORMATION REVIEW
This section provides a summary of topographic mapping, City of Federal Way Critical Areas
Map, soil survey information, NWI mapping, and other sources documenting conditions in and adjacent
to the project area.
Wetlands
The USGS topographic map, City of Federal Way Critical Areas Map, and NWI Map do not
identify any wetlands within or adjacent to the study area (Appendix A).
Waterways and Fish Use
The City of Federal Way Critical Areas Map (Appendix A, Figure A-6) identifies one stream
(identified as Lakota Creek during the field investigation) flowing southeast to northwest through the
western end of the study area. The USGS topographic map identifies Lakota Creek (not labeled).
The WDFW PHS on the Web mapping does not list any fish species present in Lakota Creek
within the study area. The WDFW PHS on the Web mapping identifies the ravine containing Lakota
Creek within the study area as a terrestrial habitat (Dash Point/Poverty Bay Open Space Area) (WDFW
2012a). The WDFW SalmonScape mapping did not identify any salmonid species within this reach of
Lakota Creek, and identified a non -fish bearing stream crossing barrier and a partial stream crossing
barrier downstream of the study area (WDFW 2012b).
Floodplains
The FEMA GIS data (Appendix A, Figure A-4) does not show any flood hazard areas within the
study area. The nearest flood hazard area is along the shoreline of the Puget Sound, over 5,000 ft to the
northwest.
Soils
The USDA NRCS Web Soil Survey identifies one soil series within the project area (Appendix
A, Figure A-5; complete soil profile reports are provided in Appendix B):
• The Alderwood (AgB, AgD, AmB) soil series consists of moderately deep to a densic
contact, moderately well drained soil formed in glacial drift (USDA, NRCS 2011 a). The
typical profile generally consists of gravelly sandy loam from 0 to 12 inches below ground
surface (BGS) over very gravelly sandy loam to 60 inches BGS (USDA, NRCS 2011b). A
perched water table is at its highest from January through March (USDA, NRCS 2011 a). The
National Hydric Soils List (USDA, NRCS website 2011) lists Alderwood gravelly sandy
loam, 0 to 6 percent slopes (AgB) as a hydric soil in depressions that contain components of
the Norma, Bellingham, Tuckwilla, Shalcar, Buckley soil series.

Arents (AmB) refers to Entisols that do not have horizons because they have been deeply mixed
by plowing, spading, or other methods of moving by humans (USDA NRCS 1999). The soils retain
fragments that can be identified as parts of former horizons, but do not themselves form horizons.
Precipitation
Precipitation data for the three month period prior to the field investigation in the Puget Sound
Lowlands (NCDC 2011) indicate recorded precipitation levels were within the normal range listed in
NRCS Wetlands Determination (WETS) tables (USDA, NRCS website 2002) and as determined using
the USDA rainfall documentation worksheet (USDA, NRCS 1997) (Appendix C) .
3.2 FIELD INVESTIGATION
Landau Associates project scientist, Jessica Stone, and wildlife biologist Molly Linville
conducted , a field investigation on November 11, 2011. The weather during the November site
investigation was overcast with rain.
Sampling points were taken in areas suspected to meet the mandatory wetland criteria. Two
sampling locations were identified in the study area to investigate presence of potential wetland. The
sampling point locations are show on Figure 2. No sampling points were conducted within the project
area as it is developed as a roadway and adjacent right-of-way areas developed primarily for residential or
commercial use.
No wetlands or waterways were identified within the project area and; therefore, no boundaries
were delineated. Site observations and existing background information including detailed information
on soils, vegetation, and hydrology from the sampling points is provided on the completed data sheets in
Appendix D. Site photographs are provided in Appendix E.
3.2.1 SAMPLING POINT SP-1
Sampling point SP-1 is located near the center of a depression identified within the forested area
located to the southeast of the intersection of SW 312`' Street and SR 509 (Figure 2). Sampling point SP-
1 satisfies only one of the three mandatory wetland criteria (see Figure 2 and Appendix D).
Sampling point SP-1 is dominated by hydrophytic forested, emergent, and upland scrub -shrub
vegetation. Dominant vegetation at sampling point SP-1 consists of:
a Red alder (Alnus rubra, FAC)
• Himalayan blackberry (Rubus armeniacus, FACU)
Reed Canary Grass (Phalaris arundinacea, FACW).
3128112 YA1187\003.02M Wetland Invesfigabon\Rnal Wetland Report_Ci y.docx LANDAU ASSOCIATES
3-2
Additional non -dominant species at sampling point SP-1 include trailing blackberry (Rubus
ursinus, FACU), cut -leaf blackberry (Rubus laciniatus, FACU), and Watson's willow herb (Epilobium
ciliatum, FACW).
During the field investigation, the soil within sample point SP-1 was damp to moist, but not
saturated. The soils contained very dark grayish brown (IOYR 3/2) sandy loam from 0 to 5 inches BGS;
from 5 to 8 inches BGS, the soils were brown (10YR 4/3) sandy loam; from 8 to 14 inches BGS, the soils
were brown to dark yellowish brown (IOYR 4/3 to 4/4) silty loam with dark yellowish brown (IOYR 4/6)
redox features; and from 14 to 20 inches BGS, the soils were grayish brown (2.5Y 5/2) silty loam with
strong brown (7.5YR 516) redox features. .
3.2.2 SAMPLING POINT SP-2
Sampling point SP-2 is located adjacent to a trail near the edge of the depression identified within
the study area (Figure 2). Sampling point SP-2 satisfied only one of the three mandatory wetland criteria
(see Figure 2 and Appendix D).
Sampling point SP-2 is dominated by hydrophytic forested and emergent vegetation and a mix of
hydrophytic and upland scrub -shrub vegetation. Dominant vegetation at sampling point SP-2 consists of.
• Red alder (Alnus rubra, FAC)
• Salmonberry (Rubus spectabilis, FAC)
• Himalayan blackberry (Rubus armeniacus, FACU)
• Trailing blackberry (Rubus ursinus, FACU)
• Reed canary grass (PhalaKs arundinacea, FACW).
Additional non -dominant species at sampling point SP-2 include beaked hazelnut (Corylus
cornuta, FACU) and Indian plum (Oemleria cerasiformis, FACU).
During the field investigation, the soils within sample point SP-2 were damp to moist, but not
saturated. The soils contained very dark grayish brown (IOYR 3/2) sandy loam from 0 to 13 inches BGS;
from 13 to 15 inches BGS, the soils were brown (10YR 513) sandy silt with brown (10YR 4/4) redox
features; and from 8 to 14 inches BGS, the soils were brown (10YR 5/3) sandy silt with strong brown
(1OYR 4/6) redox features.
3.2.3 LAKOTA CREEK
Lakota Creek was observed flowing southeast to northwest through the bottom of the forested
ravine located at the western edge of the study area. This property is privately owned and was not
accessed as part of the field investigation. There were no wetland areas associated with Lakota Creek
3/28/12 YM187T003.0201R\Welland Invesfigation\Rnal Wetland Report_City.docx LANDAU AssocIATES
3-3
identified within the study area during the background review (Section 3.1) and no distinct wetland areas
or springs were observed within the ravine from the adjacent right-of-way during the field investigation.
The data sources reviewed (Section 3.1) do not identify this section of Lakota Creek as a fish -bearing
stream.
The FWRC Chapter 15.05 identifies streams as "major streams" (contains or supports, or under
normal conditions contains or supports, resident or migratory fish) or "minor streams" (all other streams).
Major streams have a 100 ft setback and minor streams have a 50 ft setback under the FWRC. The data
sources reviewed indicate that this section of Lakota Creek is not a fish -bearing stream, and classified as a
minor stream with a 50 ft setback. All road and sidewalk improvements adjacent to the property
containing Lakota Creek will be within the existing roadway and roadway prism, and there is 100 ft
between Lakota Creek (location based on topography) and the project area (Figure 2). Should this section
of Lakota Creek be determined to be (or reclassified as) a major stream, the proposed project will not

5.0 USE OF THIS REPORT
These findings are based on our understanding of the Federal Way Revised Code, the U.S. Army
Corps of Engineers, and Washington State Department of Ecology delineation methodology, and on our
interpretation of the vegetative, soil, and hydrology conditions observed during the site reconnaissance on
November 11, 2011. Within the limitations of scope, schedule, and budget, the findings presented in this
report were prepared following generally accepted sensitive area investigation principles and practices in
this locality at the time the report was prepared. We make no other warranty, either express or implied.
This report was prepared for the use of Tetra Tech, the City of Federal Way, and applicable
regulatory agencies. No other party is entitled to rely on the information, conclusions, and
recommendations included in this document without the express written consent of Landau Associates.
Further, the reuse of information, conclusions, and recommendations presented for extensions of the
project or for any other project, without review and authorization by Landau Associates, shall be at the
user's sole risk.
Wetland/waterway areas delineated by Landau Associates are considered preliminary until the
USACE and/or local jurisdictional agencies validate the wetland boundaries. Because wetlands are
dynamic communities, wetland boundaries may change over time. The agencies typically recognize
wetland delineations for a period of five years following an approved jurisdictional determination. In
addition, changes in government code, regulations, and/or laws may occur.
This document has been prepared under the supervision and direction of the following key staff.

METHODS FOR WETLAND DETERMINATION

FEDERAL WAY, WASHINGTON
Parameter Definition Field Indicators Field Assessment
Wetland Vegetation Wetland vegetation is adapted to saturated soil conditions. The U.S. Fish and Wildlife Service has
(a) assigned a wetland indicator to each plant species that denotes its frequency of occurrence within
wetlands (Reed 1988 and 1993). These are:
• Obligate (OBL) wetland plants occur almost always in wetlands under natural conditions (more
than 99 percent of the time)
• Facultative wetland (FACW) plants usually occur in wetlands (67 to 99 percent of the time) but
are occasionally found in non wetlands
• Facultative (FAC) plants are equally likely to occur in wetlands or nonwetlands (34 to 66
percent of the time)
• Facultative upland (FACU) plants usually occur in nonwetlands, but are occasionally found in
wetlands (1 to 33 percent of the time)
• Obligate upland (UPL) plans almost always occur in uplands (more than 99 percent of the
time).
Modifiers:
+ Frequency toward the higher end of the category (more frequently found in wetlands).
Frequency toward the lower end of the category (less frequently found in wetlands).
Tentative assignment based on limited information from which to determine the indicator status.
Wetland Soils (b) Soils are classified as hydric, or they possess characteristics that are associated with reducing soil
conditions. A hydric soil is formed under conditions of saturation, flooding, or ponding long enough
during the growing season to develop anaerobic conditions in the upper part of the soil.
Wetland Hydrology The area is inundated either permanently or periodically at mean water depths less than or equal to
(c) 6.6 ft, or
The soil is inundated or saturated to the surface for at least 14 consecutive days during the growing
season (d).
More than 50 percent of the dominant plants totaled from all vegetation strata are
hydrophytic, i.e., those species with indicators of OBL, FACW, or FAC
(regardless of modifier), or
A plant community has a visually estimated cover percentage of OBL and FACW
species that exceeds the coverage of FACU and UPL species. If dominance is
not met, the Prevalence Index is calculated, or consideration is given to
morphological adaptations and/or non -vascular plants observed.
Hydric soils have an identifiable color pattern, which occurs if the soil is
saturated, flooded, or ponded for a long period of time. Faint or washed-out
colors typically form in the soil, and mottles of bright color, such as rust (known
as redoxymorphic features), form. Accumulations of organic matter at the
surface, a sulfur odor, and organic matter stains may also be present.
Page 1 of 1
1. Dominance: The dominant plants and their wetland indicator status are evaluated
quantitatively within data plots and visually throughout the study area. If the test for
dominance fails, and indicators of wetland soils and hydrology are present, the Prevalence
Index is calculated.
2. Prevalence Index: A weighted average of the percent cover of each indicator status is
calculated (see data sheets in Appendix D). An index of 3 or less is considered meeting the
hydrophytic vegetation criterion. If the Prevalence Index is not met, the consideration is given
to morphological adaptations and/or non -vascular plants.
3. Morphological Adaptations/Non-Vascular Plants: Some plants develop recognizable
morphological adaptations when occurring in wetland areas. These features must be
observed on >50 percent of the individuals of an FACU species living in an area where
indicators of hydric soils and wetland hydrology are present. Wetland non -vascular plants can
include bryophytes (mosses, liverworts, hormworts). The cover of wetland bryophytes must be
>50 percent of the total bryophyte cover in a plot in coastal Washington forested wetlands.
A shovel is used to dig holes at least 20 inches BGS at multiple locations in the study area.
Direct observation of the soil is made at multiple locations in both wetlands and uplands, as
applicable. Soil organic content is determined visually and texturally, and soil color is
determined using the Munsell soil color chart (Greytag Macbeth 1994). Depth to water
saturation and/or inundation is also observed (see Wetland Hydrology). The characteristics
observed are compared to the hydric soil indicators for "all soils," "sandy soils," and 'loamy
clayey soils," as described in the USACE Regional Supplement (USACE 2010).
Primary indicators of wetland hydrology include surface inundation (standing During investigation of soils, soil pits are allowed to stand for up to 20 minutes in order to allow
water), saturated soils, water marks, drift lines, sediment deposits, and drainage percolation of any groundwater into the pit to determine groundwater level in the soil profile.
patterns. Secondary indicators of hydrology include water -stained leaves, Additional digging may occur to 24 inches BGS during the dry season to investigate
oxidized root channels, or local soil survey data for identified soils. In the groundwater levels. In addition, the extent of soil saturation and presence/absence of
absence of any primary indicators, at least two secondary indicators are required oxidation are determined in the soils removed as part of the soils investigation (see Wetland
to meet the wetland hydrology criterion. Soils). Other indicators of wetland hydrology are observed at ground surface.
Notes:
(a) Categories were originally developed and defined by the USFWS National Wetlands Inventory and subsequently modified by the National Plant List Panel.
(b) USACE 1987, 2010; USDA, NRCS 2006.
(c) USACE 1987, 2010.
(d) The growing season is the time during which two or more non -evergreen vascular plant species growing in a wetland or surrounding area exhibit biological activity, such as new growth. Growing season can also be determined by soil temperature.

COMPETING SERIES: This is the Whidbey series. Whidbey soils are dry 75 to 90
consecutive days following the summer solstices.
GEOGRAPHIC SETTING: These soils are on till plains and moraines at elevations of
0 to about 245 meters. Slope is 0 to 65 percent. The soils formed in glacial till.
Alderwood soils are in a cool marine climate. The summers are cool and dry, and the
winters are mild and wet. Mean annual precipitation is 200 to 1500 cm, most of which
falls as rain from November through March. Mean January temperature is 3 degrees C,
mean July temperature is 16 degrees C, and mean annual temperature is 10 degrees C.
The growing season (-2 degrees C) is about 200 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Beausite, Dick, Everett,
Hoogdal, Indianola, Kitsap, Norma, Quilcene, Skipopa and Whidbey series. All of these
soils except Whidbey soils lack a densic layer within 100 cm. In addition, the Beausite
soils have a lithic contact at 50 to 100 cm. Dick, Hoogdal, Indianola, Kitsap, and Skipopa
soils have less than 35 percent coarse fragments. Everett soils are sandy -skeletal.
McKenna soils have an aquic moisture regime. Norma soils have an aquic moisture
regime of less than 35 percent coarse fragments in the upper part of the control section.
Quilcene soils are in a fine family.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately
well drained; high saturated hydraulic conductivity above the densic layer and low
saturated hydraulic conductivity in the densic material. A perched water table is at its
highest from January through March.
USE AND VEGETATION: Used mostly for woodland, field crops, hay and pasture,
orchards, vineyards, wildlife habitat, watershed, and non -farm uses. The natural
vegetation is Douglas -fir, western hemlock, western redcedar, and red alder with an
understory of salal, Oregon -grape, western brackenfern, western swordfern, Pacific
rhododendron, red huckleberry, evergreen huckleberry, and Orange honeysuckle.
DISTRIBUTION AND EXTENT: Northwestern Washington; MLRA 2. The series is
extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland,
Oregon
SERIES ESTABLISHED: Snohomish County, Washington 1936.
REMARKS: Diagnostic horizons and features recognized in this soil:
Ochric epipedon
Cambic horizon - from 18 to 89 cm
Densic contact - from 89 to 150 cm
Aquic feature - redox depletions with chroma of 2 or less at 75cm.
Humic subgroup - meet color requirement from 0 to 18 cm.
Particle -size control section - 25 to 89 cm.
The current typical pedon is borderline in meeting the Aquic subgroup criteria and is also
borderline in meeting Humic subgroup criteria. Based on the range of characteristics, the
present classification is marginal to being Aquic subgroup and marginal to not meeting
Humic subgroup criteria. It is recommended a new typical pedon be selected to represent
the series concept and classification.
The series has had a long history in classification, much of it involves the cementation or
not of the upper part of the glacial till. The series in 1978 started as a loamy -skeletal,
mixed, mesic Dystric Entic Durochrepts, then in 1988 to a loamy -skeletal, mixed, mesic,
ortstein Aquic Haplorthods, then in 1994 to a loamy -skeletal, mixed, mesic Vitrandic
Durochrepts, then in 2000 to a loamy -skeletal, isotic, mesic Vitrandic Dystroxerepts and
in 2011 to a loamy -skeletal, isotic, mesic Aquic Dystroxerepts. The 89 to 109 cm horizon
is the horizon in question as to cementation or not, and if cemented, what is the
cementing agent. The material was studied in the late 1960's and early 1970's and it was
though at that time to be cemented, but the cementing agent was not easily identifiable.
The strength of Vitrandic properties in the upper part of the solum is very weak. Given all
this change in classification the typical pedon has remained the same and the concept of a
moderately deep and moderately well drained soil has remained the same.
An in depth study of the glacial till is needed throughout the Puget Sound foothills on
several similar soil series.

1.0 INTRODUCTION
This report presents the results of a Corridor -Wide Screening Level Environmental Site
Assessment (ESA) conducted for Tetra Tech INCA and the City of Federal Way (City) for the south side
of SW 312th Street from 14`h Avenue SW to State Route (SR) 509 improvement project. The purpose of
the project is to improve pedestrian movement and safety along the south side of SW 312'' Street from
approximately 200 feet (ft) to the west of SR 509 to the west side of the intersection at 14`" Avenue SW,
in Federal Way, Washington. The project area includes properties adjacent to the project alignment.
Land use in the project area consists of commercial, public, and undeveloped land. The purpose of this
ESA is to assess the potential for hazardous substances or wastes that exist within the project area to the
extent that they have the potential to affect the planned roadway improvement project. Figure 1 presents
a vicinity map of the project area. The project area includes the following parcels and addresses (also see

1.2 SCOPE OF SERVICES
Landau Associates conducted this Corridor -Wide Screening Level ESA for Tetra Tech INCA and
the City. Authorization for these services was provided by Tetra Tech INCA on August 8, 2011. The
scope of services performed, as established in our contract dated June 15, 2011, consisted of the following
specific tasks:
• Complete a Corridor -Wide Screening Level ESA of the roadway corridor. Specific tasks were
conducted in general accordance with the American Society for Testing and Materials
(ASTM) International Standard Practice for Environmental Site Assessments: Transaction
Screen Process, E1528-06, as applied in Washington State and modified as appropriate for
this project including:
— Conduct a visual reconnaissance from public access areas and from the public ROW of
the adjacent parcels along the proposed corridor alignment to assess current land use
activities and environmental conditions
— Review historical sources of information including historical topographic maps and aerial
photographs to assess past land uses and activities in the project area and the surrounding
area
— Obtain and review listings from Environmental Data Resources, Inc. (EDR) of confirmed
and suspected contaminated sites abstracted from federal, state, and local agency
environmental databases as prescribed by ASTM.
• Prepare and submit this report summarizing our findings and conclusions related to
environmental conditions in the project area.
A summary of the ESA Elements can be found in Table 1.
The ESA process is not a means of fording everything there is to know about a property. Rather,
it is to identify potential environmental concerns as identified in the ASTM E 1528-06 standard and
evaluate the environmental liabilities associated with a property or properties based on reasonably
available documentation (both oral and written) within the budget, schedule, and project -specific
limitations.
1.3 LIMITATIONS AND EXCEPTIONS
The following summarizes exceptions, limitations, or restrictions to the scope of work:
• Properties adjacent to the project area were only viewed from accessible areas within the SR
509, SW 3121h Street, 21st Avenue SW, and 14th Avenue SW ROWs. Due to heavy vegetation
and obstructions, many areas could not be fully observed.
■ No interviews with property owners or persons knowledgeable with properties adjacent to the
project area were conducted for this report due to access restrictions.
Data gaps that were identified during performance of this Corridor -Wide Screening Level ESA
are discussed in the findings and conclusions section of this report.

2.0 SITE DESCRIPTION AND SETTING
The project area is located in a predominantly commercial and public area along SW 312`s Street
between 20 Avenue SW and 14`h Avenue SW, in the City of Federal Way, Washington. Figure 2 shows
the project and surrounding areas.
2.1 PROJECT AREA DESCRIPTION
As observed during Landau Associates' February 23, 2012 site reconnaissance, the portion of the
south side of SW 312"' Street that will be improved during the project is approximately 1,050 ft in length
and extends west to east along four parcels starting approximately 200 ft west of the intersection with SR
509 and ending at the west side of the intersection with 14th Avenue SW. Table 2 lists the four parcels
included in the project area and includes a description of the current land use; Figure 2 shows the parcel
locations along the proposed alignment.
2.2 PROPERTIES IN SURROUNDING AREA DESCRIPTION
The surrounding area is primarily commercial and public properties and undeveloped areas. To
the north are the Dash Point shopping center, gas stations, and residential and undeveloped properties. To
the east are residential properties and the Puget Sound Energy (PSE) Lakota substation. To the south are
undeveloped properties, a fire station, Lakota Park, and Lakota Middle School. To the west is a church,
and residential and undeveloped properties.
2.3 SITE GEOLOGY AND HYDROLOGY
2.3.1 TopoGxarnY
The description of the existing conditions in the project area was developed from aerial
photographs, 7.5-minute U.S. Geological Survey (USGS) Poverty Bay Quadrangle topographic maps
(USGS 1997), and a visual reconnaissance of the project area and surrounding area. The topography is
relatively flat from east to west along SW 312"' Street; the elevation at the eastern limit of the project area
is about 300 ft mean sea level (MSL) and then decreases to about 265 ft MSL at the western limit of the
project area.
2.3.2 GEOLOGY
The Puget Sound region is underlain by Quaternary sediments deposited by numerous glacial
episodes, the most recent of which is termed the Vashon Stade of the Fraser Glaciation. Deposition
occurred during a number of glacial advances and retreats. The last cycle of glacial advance and retreat
3/27/12 \\tacoma1\Data\DATA\PR0JECT11187\003.020\R\PH I ESA_CITY\Final Phase I ESA_City.docx LANDAU ASSOCIATES
2-1
resulted in the present-day topographic expression of the area, many of the near -surface deposits, and
existing subsurface conditions. The glacial sediments are made up of interlayered and sequential deposits
of glaciomarine drift, glacial recessional outwash, and glacial till. The glacial till has been
overconsolidated due to the weight of the overriding ice sheets. These glacial sediments are overlaid with
more recent deposits locally consisting of beach sands and gravels; alluvial silt, sands, and gravels; and/or
lake clays, silts, and peat that were deposited following the glacial retreats (Heller 1979).
General geologic information for the project area was obtained from the Geology of the Poverty
Bay Quadrangle, Washington (Booth et al. 2004), published by the USGS. According to the geologic
map, near -surface deposits in the project area consist primarily of glacial till. Deposits mapped as "till"
typically consist of a dense to very dense, unsorted mixture of boulders, cobbles, gravel, and sand in a
matrix of silt and clay with some lenses of poorly sorted to sorted, stratified sand and gravel. The glacial
till unit typically exhibits low to very low permeability and high shear strength characteristics resulting
from compaction by the weight of the overlying glacier.
2.3.3 SURFACE WATER AND GROUNDWATER
As noted in Section 2.3.1, the project area is located at approximately 265 ft to 300 ft above MSL
(USGS 1997). The nearest mapped surface water body is Mirror Lake located approximately 2,000 ft to
the east at an elevation of approximately 300 ft MSL. Lakota Creek flows to the northwest west and south
of the project area toward Puget Sound.
Reports for resource protection wells located on a property approximately 200 ft to the west of
the project area indicate that the static groundwater levels in the wells were measured at between 50 ft and
60 ft below ground surface (BGS) [Washington State Department of Ecology (Ecology) website 2012a].
Based on area topography, the direction of regional groundwater flow is anticipated to be to the west-
southwest toward Commencement Bay.
In addition to the regional groundwater, it is anticipated that shallow, perched groundwater is
locally present overlying the glacial till throughout the project area. Perched groundwater may not be
present during the dry season and, if present, the depth and occurrence of the perched groundwater is
anticipated to fluctuate seasonally and to follow local topography.
2.3.4 FLOOD PLAIN
Based on U.S. Federal Emergency Management Agency (FEMA) flood plain zone maps, there
are no 100- to 500-year flood plains mapped within the project area or surrounding area.

3.0 HISTORICAL INFORMATION
A variety of sources were reviewed to develop the history of the project area and adjacent
properties to assess the potential for site contamination. These resources include the following:
Aerial photographs (AeroMetric, Inc. 1960, 1974, and 1980; King County 1936 and 1998;
and Google Earth 2011)
USGS topographic maps (1900, 1961, 1968, 1973, 1981, 1994, and 1997).
Copies of the historical aerial photographs and topographic maps are provided in Appendices A
and B, respectively. Landau Associates requested Sanborn Fire Insurance maps for the project area;
however, EDR responded that no coverage is available for the project area (Appendix B). Historical
information for the project area and surrounding area dates back to 1900 (the first available USGS
Topographic map for the project area).
3.1 HISTORY OF PROJECT AREA AND VICINITY
The table below presents a summary of the operational history of the project area developed from
review of the aerial photographs and topographic maps, as presented in the sections below:
SUMMARY OF PROJECT AREA HISTORY
DATES PAST PROJECT AREA USE(S)
At least 1900 - SW 312`h Street extended east to west in the central portion of the project area. Properties in the
approximately 1960 project area were primarily undeveloped forested and cleared areas. A small building was located
near the southwest comer of the intersection of 21't Avenue SW and SR 509.
Approximately 1960 - By 1974, the current fire station was developed to the southwest of the SW 312`h Street and 14�h
current Avenue SW intersection. Athletic fields were constructed at Lakota Park and three small
residences were constructed on and adjacent to the Federal Way Self Storage property. The small
building near the southwest comer of the intersection of 21 t Avenue SW and SR 509 was
removed.
By 1998, the project area was similar to its current state of development. The three residences on
and adjacent to the Federal Way Self Storage property were removed and the current facility was
under construction.
The table below presents a summary of the operational history of the surrounding properties that
were developed from review of the aerial photographs and topographic maps, as presented in the sections
below:
SUMMARY OF HISTORY OF PROPERTIES IN SURROUNDING AREA
DIRECTION PAST SURROUNDING PROPERTY USE(S)
North The adjacent properties to the north were cleared by 1960 and developed with residential and commercial
buildings by 1974. By 1998, the Dash Point Village Shopping Center, Chevron Station, and ARCO Gas
Station were developed to their current configuration.

SUMMARY OF HISTORY OF PROPERTIES IN SURROUNDING AREA
DIRECTION PAST SURROUNDING PROPERTY USE(S)
East The adjacent properties to the east were cleared and developed with residences and the PSE Lakota
Substation was present by 1974.
South The adjacent property to the southwest was cleared and developed with the Lakota Middle School and parking
lots since at least 1960. Adjacent properties to the southeast were developed with a residential subdivision by
1974 and the fire station to the south.
West By 1974, adjacent properties to the west were developed with multiple residential homes. The area
surrounding Lakota Creek primarily remains forested and undeveloped.
3.2 AERIAL PHOTOGRAPHS
Landau Associates reviewed the historical aerial photographs listed in Section 3.0. Copies of the
aerial photographs reviewed are included in Appendix A. Note that most of the photographs are
relatively high altitude images and, at that scale, any features smaller than a large building, are difficult to
identify. Historically and/or environmentally, significant findings from the aerial photograph review are
summarized below:

SUMMARY OF AERIAL PHOTOGRAPHS
YEAR
PROJECT AREANICINITY USE
1974
Project Area - The property at the southwest corner of SW 312`h Street and 14th Ave SW appears to be developed
with a large building and parking lot to the southwest (in the current configuration of the fire station on this
property). A portion of the property to the southeast of the intersection of SR 509 and SW 312`h Street has been
cleared and developed with two small structures and an athletic track is visible further to the southeast. The
building at the southwest comer of the intersection of SR 509 and 21" Avenue SW is no longer visible. Three
residences are visible on the northwestern edge of the project area.
Adjacent Properties - The property on the northeast comer of SR 509 and SW 312th Street appears to be
developed with a large commercial building and parking lot. The property at the southeast comer of SW 312th
Street and 14" Avenue SW appear to be developed with,electrical utility structures to the southeast (in the current
configuration of the electrical substation on this property). 14`h Avenue SW is visible extending north from SW 3121h
Street in the northeastern portion of the project area. The adjacent properties to the north of the project area have
been developed with eight residences and a large building that appears to be a church. The buildings visible in the
1936 and 1960 photographs to the west of SR 509 off of 21�` Avenue SW have been replaced by a large
irregularly -shaped commercial building, a small commercial building, and a large parking lot that occupies the
northwest comer of the intersection of SR 509 and SW 312th Street. The adjacent properties to the east and
southeast of the project area have been developed with a residential subdivision.
1980
Project Area - The project area appears relatively unchanged from the previous aerial photograph.
Adjacent Properties - Adjacent properties to the north appear relatively unchanged with the exception that a large
building and parking lot have been developed adjacent to the north of the project area. The commercial building
comelex visible in the 1974 photograph that occupies the northwest comer of the intersection of SR 509 and SW
312 Street appears to have been expanded. Additional small structures are visible on the property on the
northeast comer of SR 509 and SW 31P Street. The adjacent properties to the south and east of the project area
appear relatively unchanged from the previous photograph.
1998
Project Area - The three residences on the northwestern edge of the project area have been removed, and the site
appears to be under development. A trail is visible on the property southeast of the intersection of SR 509 and SW
312th Street, extending from the intersection to the large institutional building adjacent to the south (what is now
Lakota Middle School).
Adjacent Properties - The buildings visible in the 1974 and 1980 photographs on the property on the northeast
comer of SR 509 and SW 312`h Street have been replaced with two buildings in the current configuration of the
ARCO gas station and mini -mart that occupies this property. Adjacent properties to the north and south appear
relatively unchanged from the previous photograph, with the exception that the commercial building complex that
occupies the northwest comer of the intersection of SR 509 and SW 312`h Street appears to have been expanded.
The small commercial building in this complex visible in the 1974 photograph appears to have been replaced by
four commercial buildings. An area of the property adjacent to the east of the project area (and north of SW 312
Street) appears to have been cleared; a residential subdivision is visible further to the east.
2011
Project Area - The development seen in the previous aerial photograph on the northwestern edge of the project
area now contains three long buildings (Federal Way Self Storage).
Adjacent Properties - The adjacent properties to the north, south, east, and west of the project area appear
relatively unchanged from the previous photograph with the exception that a property to the north of SW 312th
Street has been cleared and developed with a parking lot and the large institutional building visible in the 1960
photograph to the southwest of the project area has been replaced by two large irregularly -shaped buildings (what
is now Lakota Middle School).
The review of historical aerial photographs for the project area and vicinity did not identify any
potential environmental concerns for the project area.

4.0 AGENCY AND COUNTY RECORDS REVIEW
Landau Associates reviewed information from publicly available regulatory databases for
information regarding potential environmental conditions at the project area or the adjacent properties.
Information collected during the review of agency records is summarized below.
4.1 REGULATORY DATABASE REPORT
EDR was subcontracted to conduct a search (as prescribed by ASTM) of publicly available
federal, state, and local agency environmental databases. A regulatory agency database report was
obtained from EDR, a complete copy of which is provided on compact disc (CD) in Appendix C.
The search focused on information in the various lists maintained by the agencies of sites with
known and potential environmental conditions that may represent a threat to human health or the
environment. EDR conducted its search of listed information (which is keyed to a geographic mapping
system) using the location of the project area and identified sites listed in the databases that are located
within up to a 1-mile radius of the project area boundaries. Not all sites located within the 1-mile radius
are considered to represent a potential threat to the project area. In general, only properties that are
hydraulically upgradient or adjacent to the project area and that have had a documented release to soil or
groundwater are considered to have the potential to impact the project area. For the project area, sites that
are east and northeast are considered hydraulically upgradient, based on anticipated groundwater flow to
the west-southwest (Section 2.3.3).
4.1.1 PROJECT AREA
The EDR database report identified one site, Federal Way Fire Department (Fire District #39),
within the project area. This site is shown on Figure 2. Comments are provided on the relative threat that
this site poses to the project area, based on available information:

This site is listed in Ecology's Reported SPILLS database for two incidents: one on August 14, 2007 and one on March 11, 2008.
Both incidents were listed as a spill of an unreported quantity of an unreported chemical to an unreported medium. No further
information was available in the EDR database report, nor in Ecology's Facility/Site online database (Ecology website 2012b). This
site was observed from the public ROW during the site reconnaissance and no evidence of a release was observed. Based on the
age of the spills, the lack of a report that the spills resulted in a release to soil, and because ROW will not be acquired from the fire
station property, these listed spills are considered to have a low potential to impact the project area.
4.1.2 ADJACENT AND PROXIMATE SITES
Seven listings for adjacent and proximate sites were identified in the EDR database search. Of
the identified sites, two are located more than % mile away from the project area. The potential for
impact to the project area from these sites is considered to be very low. Of the remaining five sites
located within r/a mile, three are located adjacent to the subject property and have a confirmed release to
soil and/or groundwater. These sites include the Dash Point Arco, Chevron Dash Point, and Westfair
Cleaners. Comments are provided on the relative threat that these sites pose to the project area, based on
available information. The remaining two sites are either hydraulically downgradient of the project area
or had no documented releases to soil or groundwater; therefore, the potential for impact to the project
area from these two sites is considered to be very low:

5.0 SITE RECONNAISSANCE
Representatives of Landau Associates conducted a site reconnaissance on January 31 and
February 23, 2012 to observe conditions within and adjacent to the project area, assess land uses in the
project vicinity, and confirm the location of sites identified in the EDR report. Access was not provided,
so the project area properties were observed from the ROWS along SW 3121h Street, 14th Avenue SW, SW
314'h Street, 21" Avenue SW, and SR 509. Observations made during the site reconnaissance were
documented with photographs and notes recorded on a site reconnaissance checklist. Selected
photographs are presented in Appendix D and site features are shown on Figure 2. Conditions noted and
observed at the time of the reconnaissance include the following:
SUMMARY OF SITE RECONNAISSANCE WITHIN PROJECT AREA
ADDRESS
OBSERVATIONS
Federal Way Self Storage
This property consists of a gated self storage facility and appears to be well maintained. The
31119 21" Way SW 98023
facility is located on a narrow stretch of ground adjacent to the west of 12st Avenue SW,
and extends onto the three adjacent properties to the west. Due to the position of the
Parcel No. 1221039025
building and fencing, the remainder of the facility could not be observed. The remainder of
the property is densely forested. The ground slopes steeply to west down to Lakota Creek.
which flows east to west through the southern half of the property.
Vacant Land
This property consists of undeveloped forested land. Due to dense forest vegetation, the
31241 SW Dash Point Road
interior of this property could not be observed. The ground slopes steeply to west from SW
98023
314"' Street down to Lakota Creek, which flows southeast to northwest through the eastern
half of the property. Areas of this property that are visible from SW 314`h Street and SR 509
Parcel No. 1221039147
ROW did not appear to have been impacted by dumping.
Lakota Park
Due to the large size of this propel and its use as open space and a park, only the
31250 SW Dash Point Road
northern half adjacent to SW 312` Street and SR 504 was observed during the
fields
98023
reconnaissance. This area of the property contains several sports
(baseball/softbaIUsoccer) and a running track. A paved parking lot and small building are
Parcel No. 1221039016
located at the western end of the property adjacent to SR 509. Mapping shows Lakota
Creek flowing north from the Lakota Middle School property, through Lakota Park and to the
northwest to the Vacant Land property discussed above; however, it was not observed an
the Lakota Park Pro�erty. Lakata Creek possibly flows through a culvert under the Lakota
Park area. SW 34 Street runs northwest to southeast through the northern end of the
property, connecting SR 509 to the Lakota Middle School. A small section of Lakota Park to
the north of SW 314T Street is densely vegetated and contains a walking path that extends
from the intersection of SW 312`° Street and SR 509 to Lakota Middle School.
Fire District #39
This property is developed with a fire station, a fire and rescue training center, and two large
1405 SW 312th Street 98023
paved parking lots in the eastern portion of the property; a large area of undeveloped
forested land occupies the western portion of the property and a strip of land along the
Parcel No. 0721049209
southern property boundary. The single -story fire station building is located in the northeast
portion of the property and a four-story rescue training building is located in the southern
portion of the property. Multiple vehicles and storage sheds are observed in the parking lot
to the south of the fire station building. A forklift, a man -lift, a mobile generator, a boat
outboard motor, a 3BQ, and a small propane tank were observed in the parking area to the
east of the fire station building under a carport structure. This property appears to be well
maintained and no evidence of spills or releases was observed during the site
reconnaissance.
5.1.1 ADJACENT AND PROXIMATE SITES
Three adjacent properties were identified as having the potential to impact the project area during
the site reconnaissance: the Chevron Station, the ARCO gas station, and the location of a former dry

cleaner at the Dash Point Shopping Center.
The Chevron Station is in active use. A grotaidwater remediation system was observed between
the pump island and the station convenience store. Three groundwater monitoring wells were observed at
this property. Three additional monitoring wells were observed near the Starbucks adjacent to the west of
the pump island and one adjacent to the north of the station convenience store. The regulatory database
record review for the Chevron Station (Section 4.0) reported this site as having a LUST with petroleum
hydrocarbon -impacted soil and groundwater.
The ARCO gas station is in active use. Three 55-gallon drums were observed on the property.
The regulatory database record review for the ARCO gas station (Section 4.0) reported this site as having
a LUST with petroleum hydrocarbon -impacted soil. Groundwater contamination has not been confirmed.
This site is listed as "reported cleaned up" in the EDR report (Section 4.0).
Personnel working at adjacent businesses in the Dash Point Village Shopping Center identified
the H&R Block and Underhill Jewelers as the location of a former dry cleaner. A new dry cleaner, Dry
Cleaning Solutions, located at the Dash Point Shopping Center is a drop-off and pick-up location only,
and no active -dry cleaning occurs at this site. A network of over 20 monitoring wells was observed
located in front of and behind the H&R Block and Utiderliill Jewelers stores. Most of the monitoring
wells were located behind the building. Against the back of the building was a groundwater remediation
system connected (observed by cut asphalt) to the monitoring wells. The regulatory database record
review for the former dry cleaner (identified as Westfair Cleaners in Section 4.0) reported this site as
having soil and groundwater contamination by halogenated organics.
The Chevron Station and the former dry cleaner are adjacent to the north of the project alignment
and have confirmed groundwater contamination as documented in Section 4.0. Potentially impacted
regional groundwater, which is at a depth of approximately 50 to 60 ft BGS, is not anticipated to impact
the proposed project as the depth of excavation activities is approximately 2 ft to 3 ft BGS. However, any
contaminated shallow groundwater perched over the glacial till does have the potential to impact the soils
along SW 312ffi Street. A geotechnical boring conducted by Landau Associates for the proposed project,
B-2, is located within the proposed project alignment directly across from the Chevron Station and
extended down to approximately 20 ft BGS. Soils were documented as wet; however, groundwater was
not encountered and there was no evidence of contamination (i.e., odors or sheen) identified during
drilling. The other geotechnical borings (B-1, -3, and -4) conducted for the project also did not show any
evidence of contamination. Therefore, the potential for the Chevron Station and former dry cleaners to
impact the project is considered to be moderate. The potential for the ARCO gas station, which has no
record of groundwater contamination, to impact the proposed project, is considered to be low.

6.0 FINDINGS AND CONCLUSIONS
Landau Associates has performed this Corridor -Wide Screening Level ESA Phase 1 for the SW
312`h Street from 14`' Avenue SW to SR 509 improvement project in general conformance with the scope
and limitations of the ASTM practice and the scope of work agreed to for this project. The SW 312`h
Street from 10 Avenue SW to SR 509 improvement project is located along the south side of SW 312`h
Street starting at the west side of the intersection of 14`h Avenue SW and extending to approximately 200
ft west of the intersection with 509'h in Federal Way, Washington. Significant findings of this assessment
include:
The Chevron Station, located adjacent to the north near the center of the project alignment
boundary at 1650 Dash Point Road, has reported releases of petroleum hydrocarbon
contamination to soil and groundwater based on available historical and regulatory
information. The site is still undergoing groundwater remediation (Section 5.0). Due to the
proximity of the Chevron Station, there is the potential for any contaminated groundwater
perched above the glacial till to impact the project along SW 312'h Street; however, evidence
of contamination was not observed in the geotechnical boring drilled within the project
alignment adjacent to the Chevron Station. Therefore, even though this site is considered a
potential environmental concern for the project area, the potential for encountering
contamination during construction within the proposed project alignment adjacent to the
Chevron site is considered to be moderate.
The former dry cleaner, located adjacent to the north of the project alignment boundary at
1650 Dash Point Road, has reported releases of halogenated organics contamination to soil
and groundwater based on available historical and regulatory information. The site is still
undergoing groundwater remediation (Section 5.0). Due to the proximity of the former dry
cleaners, there is the potential for any contaminated groundwater perched above the glacial
till to impact the project along sW 312'h Street. However, even though this site is considered
a potential environmental concern for the project area, based on the planned excavation
depth, the potential for encountering contamination during construction within the proposed
project alignment adjacent to the former dry. cleaner site is considered to be moderate.
The ARCO gas station site, located adjacent to the north of the western project alignment
boundary at 1600 SW 312`h Street, has reported releases of petroleum hydrocarbon
contamination to soil based on available historical and regulatory information. The site is
listed as "reported as cleaned up" in the EDR report (Section 4.0). Therefore, even though
this site is considered a potential environmental concern for the project area, based on the
planned excavation depth, the potential for encountering contamination during construction
within the proposed project alignment adjacent to the ARCO site is considered to be
moderate.
6.1 DATA GAPS
follows:
The data gaps identified during our assessment and their potential impact on our findings are as
• Historical Documentation. Historical documentation such as aerial photographs for the
1940s and 1950s, and Sanborn Fire Insurance maps were not available. However, based on
3/27/12 \\tacomal\Data\DATA\PROJECn1187\003.020\R\PH I ESA_CITY\Final Phase I ESA_City.docx LANDAU ASSOCIATES
6-1
the information reviewed from the available sources and the planned project, the additional
historical information would not change the findings of our assessment; therefore, the data
gaps are not considered significant to the findings of this assessment.
6.2 OPINION AND RECOMMENDATIONS
Based on the findings of this assessment and the current project design, no additional
investigative actions are warranted as part of planning for project construction. However, due to the
potential for encountering soil or groundwater contamination during any excavation activities, provisions
should be in place for worker protection and the appropriate evaluation, handling, and disposal of any
potential contaminated soil or gouadNN ater encountered as part of project construction.

(ESA) and underground storage tank (UST) services for portions of the Old ltown
property in Edmonds. The City was acquiring property for a public park that was part of a
former service station property and a service station was formerly located across 5th
Avenue to the west of the property. The Phase i ESA identified potential contamination at
the property due to the presence of the former services stations, and the Phase II ESA was
conducted to document soil and groundwater quality at the undeveloped property
planned for use as a park. The Phase 1/11 ESA aided the City in their due diligence and risk
management for acquisition of the property. The City later encountered a UST during
construction in street right-of-way adjacent to another portion of the Old Milltown
property. Landau Associates provided emergency response support to address the UST in
accordance with applicable regulations and to protect public safety.
