Tukwila's Potential Annexation Area North Highline.
Should the City submit a Notice of Intent to annex with the Boundary Review Board for
Tukwila's Potential Annexation Area (PAA) North Highline?
BACKGROUND
On June 25, 2012, City Council held a public hearing on the annexation petition. The annexation
petition was received from the property owners representing at least 60% of the assessed value
of the proposed annexation area of Tukwila's PAA. After the public hearing City Council decided
to schedule another meeting for staff to report back with additional information regarding: a)
potential contamination and LEOFF1 liability issues; b) MPD tax; c) provide a zoning map for
the entire city. The meeting minutes from the public hearing are included as Attachment D.
DISCUSSION
A. Potential Risks and Liabilities
There are two areas of risk/liability related to the PAA overlap area: (1) Contamination issues
and (2) LEOFF 1 liabilities. Each of these is addressed below:
Environmental Liabilities: An unknown risk is whether or not there is any environmental
contamination in the right -of -ways or public storm drains and /or ditches in this area. This is due
to the area being part of the Lower Duwamish Waterway (LDW) Federal Superfund Site. In
2001, the entire Lower Duwamish Waterway (LDW) was declared a Superfund Site. due to high
levels of contamination, particularly PCBs in the river sediments. In 2002, the LDW was
identified as a Model Toxics Control Act (MTCA) site by Washington Department of Ecology.
EPA is overseeing the remedial activity at the LDW and Ecology is in charge of source control.
Several early action areas were identified as priority areas for cleanup, but the proposed
annexation area was not one of these early action areas. However two portions of the LDW
within the annexation area, one at S 96 St and one near S Director St have been identified as
areas of greater concern based primarily on PCB levels in river sediments that are above
sediment quality standards. Ecology has two source control areas in the annexation area. The
northern portion is within the SeaKing Industrial Park source control area and the southern
portion is in the West Restoration source control area. Neither has been considered a high
priority area for source control.
INFORMATIONAL MEMO
Page 2
Ecology and the EPA identify potential sources of contamination that may be impacting the
waterway. These potential sources include historical or current commercial industrial
operations, contaminants entering the waterway from spills during product shipping and
handling as well as surface runoff and storm water discharge. Through this identification
process Potentially Responsible Parties (PRPs) will be identified to contribute to the clean -up
efforts. The current owner or operator of the site will be named as a PRP (CERCLA Section
107(a)(1)). Therefore, this implicates the City in areas of ownership, upon annexation, such as
streets and storm water outfalls. Under both state and federal law the owner /operator of an
outfall is liable for contamination that is discharged from that outfall. This can also apply to
upland drainage systems which contain contaminants.
Public Works Department entered into a contract with PBS, a consulting firm, to do an initial
sampling and testing of the storm water system in the annexation area. The amount of
contamination in the right -of -way is difficult to assess without doing significant amount of testing.
The memo prepared by staff from Public Works Department and the report prepared by PBS is
included as Attachment B. These test results indicate that the contamination levels are
generally consistent with those found in urban areas and do not appear to be highly
contaminated. Public Works Department has recommended that if the City annexes this area all
storm drainage systems be cleaned with the material disposed of appropriately and then the
City should work with the Department of Ecology to perform source control inspections to
reduce the amount of contaminants entering the storm system. After the initial cleaning of the
system is completed the annual stormwater fees collected from the area are expected to cover
the annual maintenance required for this area including additional disposal costs.
Fire District Asset Transfer and LEOFF 1 Liability
When a city annexes an area served by a Fire District, the city takes over responsibility for fire
service for the annexed area. State Law provides for transfer of assets and liabilities between
the District and the City. Asset transfer rules are designed to ensure that the taxpayers in the
Fire District are treated equitably upon annexation.
Asset Transfer Rules
If More than 60% of Area

For annexations involving more than 5% but less than 60% of the District's area, the District will
be required to transfer at least some of its assets to the City. These transfer payments are to
ensure that the taxpayers in the annexed area get to "take with them" the assets that they have

funded over the years. General obligation debt is not affected as these debts are to remain with
taxpayers as though no annexation had occurred. Thus they are treated as liabilities of the
taxpayer and not the District.
North Highline Fire District Assessed Value and Area Breakdown
Area Total AV Percent
Burien Annexation Area $1,483,881,817 92.9%
Tukwila Annexation Area $113,195,300 7.1%

Tukwila's annexation area would represent 6.6% of the North Highline Fire District service area
and 7.1 of the District's assessed value. Based on these percentages the city would not be
responsible for any of the District's liabilities, though taxpayers in the annexation area would
continue to be responsible for the District's general obligation debts. Operationally the City
would be capable of serving the area within its existing levels of service and staffing levels.
LEOFF 1 Lona -Term Medical Liabilitv. The North Highline Fire District currently has 11 retired
fire fighters in the LEOFF1 retirement program. These LEOFF1 participants are entitled to full
coverage of health care costs, including out -of- pocket expenses. According to a State Attorney
General opinion, these LEOFF1 medical liabilities are not subject to the asset transfer rules.
B. MPD Tax
City Council had asked staff to report back and confirm if the annexed area would be subject to
the Metropolitan Pool District tax. The annexed area would be subject to MPD tax in the amount
of $.15/$1000 of assessed valuation. It is important to note that the timing when the annexation
becomes effective determines when the city is able to collect taxes.
C. Zoning Map
If the Council decides to annex this area, they must also adopt the zoning for the area.
Tukwila's Comprehensive Plan designated this area as Manufacturing Industrial Center /Heavy
(MIC /H) and two parcels west of 14 Ave S and south of S. Director St are designated as
Manufacturing Industrial Center /Light (MIC /L). The staff report for June 25 meeting included
comprehensive plan map of the annexation area, but Council asked for an overall map of the
city to see all the areas that are zoned MIC /H and MIC /L. The city's zoning map is included as
Attachment C.
FINANCIAL IMPACT
Anticipated revenue and expenditure analysis was provided at the public hearing on June 25,
2012. The anticipated revenue projections for this area are approximately $487,000 per year for
general fund and $81,000 per year for storm water enterprise fund. These projections are
approximate and do not include utility tax, as data showing actual usage was not available at
this time. Also, the exact number of employees in the area could not be ascertained at this time.

Financial risks associated with potential contamination responsibility are similar to Fire District 1
annexation, when the city annexed all the industrial land along East Marginal Way S.
RECOMMENDATION
Staff recommends that City Council adopt the attached resolution authorizing staff to file a
notice of intent to annex with the Boundary Review Board (BRB).
NEXT STEPS
After the Council makes a decision on the annexation, staff will prepare an annexation packet
for submission to the Boundary Review Board (BRB). Analysis of how the proposed annexation
complies with Growth Management Act, County Wide Planning Policies, and BRB review criteria
(RCW 36.93.170) is required to be submitted with the Notice of Intent to annex.
After BRB approval, the City Council shall adopt an ordinance annexing the area to the City of
Tukwila and adopting the zoning for the area.

Subject: North Highline Annexation Storm System Sediment Analysis
PBS Engineering and Environmental has completed an analysis of the North Highline
Annexation area storm water system. This analysis consisted of reviewing previous testing
results for the area and sampling and testing sediment from five locations. The locations were
chosen to give a representative sampling of the entire area and determine what areas may have
contamination that will require special handling and disposal costs.
PBS determined that sediments within the storm system do not appear to be highly
contaminated and the contamination levels. are generally consistent with those found in urban
environments. The contaminants of concern that were identified are RCRA priority metals
(particularly arsenic, chromium, lead, silver, and zinc), total petroleum hydrocarbons (TPH) in
the heavy oil category, and polynuclear aromatic hydrocarbons (PAHs). PAHs and TPHs
appear to be originating within the annexation area, while metals are coming from both within
and upstream of the annexation area.
It is recommended that if the City annexes this area, all storm drainage systems be cleaned with
the material disposed of in an approved manner. For the system that feeds S. 96 St. pipe and
the material within the ditch in front of the wrecking yard, this material will need to be disposed
of at an approved landfill. Tipping fees for this material is currently $125 per ton vs. $80 per ton
for standard vactor waste at the King County site. Sediments in Hamm Creek and the ditch
along West Marginal Way were all below thresholds so they will not require special handling or
additional disposal costs. Once the system has an initial cleaning, the City should work with the
Department of Ecology to perform source control inspections to reduce the amount of
contaminants entering the storm system. Future cleaning efforts will also require additional
testing and may require disposal at an approved landfill.
Once the initial cleaning of the system is completed, the estimated $82,500 in additional surface
water fees is expected to cover the annual maintenance required for this system including
additional disposal costs.

City of Tukwila, WA North Highline Annexation Storm System Sediment Analysis
1.0 INTRODUCTION
The City of Tukwila, WA (City) is actively considering annexation of a portion of King County property
located along the west bank of the lower Duwamish waterway between City of Seattle property to the
north and City of Tukwila property to the south. The area is referred to as the "North Highline" area or
alternatively as the "Duwamish Industrial Triangle The City is currently evaluating the potential costs
and liabilities associated with the annexation proposal. A concern for the City is the history of potential
contamination in this area from industrial uses. The entire Lower Duwamish Waterway (LDW) is a
Superfund Site, and while the North Highline area has not been identified as one of the more
contaminated portions of the waterway, contamination has been found in sediment and water samples
from the Duwamish waterway in the vicinity of the annexation area. The Public Works Department is
specifically concerned about potential costs of taking over the King County owned stormwater sewers
that flow through or drain this area if sediments removed from these pipes during regular maintenance
contain high levels of contamination and require special disposal. Cleanup of the storm pipes could also
be required by the Washington State Department of Ecology (Ecology) if this area is identified in a
source control investigation.
PBS Engineering and Environmental Inc. (PBS) has prepared this report to assist the City in evaluating
the level of sediment contamination present in the King County owned stormwater system and the
ramifications with regard to disposal of sediments removed during maintenance.
2.0 BACKGROUND
2.1 Site Description
The North Highline area is roughly triangular in shape and borders the Lower Duwamish Waterway to
the east, West Marginal Way to the south and west, and S. Director Street to the north. The annexation
area also includes the interchange of Des Moines Memorial Drive and West Marginal Way. Land use
within the annexation area is predominantly light industrial. Seattle City Light owns the southern third of
the annexation area and has an electrical substation on this property. Other uses within the annexation
area include a large boat builder, an industrial supply company, marine industries, auto repair, the
Duwamish Yacht Club, wineries, a barge dock, light manufacturing and industrial shops, warehouses,
and an office complex.
The annexation area is located at the top (south end) of the Duwamish waterway between river miles
3.8 and 4.5. The upper turning basin which marks the end of the waterway is immediately south at river
mile 4.6. Tidal influence extends up river past the turning basin. The annexation area is mostly flat with
an average elevation of 20 feet above sea level. Mean higher high water of the Duwamish River at this
location is approximately 9 feet. Mean lower low water is approximately -2.4 feet. Since the bottom
elevation of the S 96 St. storm drain is 10 feet or more below the surface through the annexation area,
it would be possible for high tides or high river levels to come into the pipe.
2.2 Site History
Prior to straightening and dredging of the Duwamish River in the early 1900's, several forks of Hamm
Creek used to come together in the middle of the annexation area and most of the area was likely
dominated by wetlands. The Duwamish River at this location meandered across a wide floodplain and
two meander loops bordered the east side of the annexation area, one near the south end and one
near the north end. A 1938 aerial photograph shows the entire area in agricultural use. Industrial uses

of the waterway became dominant beginning in the 1940s and gradually expanded. The last 20 years
has seen little change in land use.
2.3 Stormwater System
There are three general stormwater drainage basins within the annexation area.
The portion north of S 93rd St appears to drain to a stormwater pipe in S. Director Street that
then discharges to a pipe that flows north under S. Dallas St. to eventually discharge to the
Duwamish near S. Southern St. We assume this system is owned and managed by King
County.
The middle portion of the site between S. 93 St. and S. 96 St. drains into a large 72 inch
diameter King County stormwater main that flows through the annexation area under S 96 St.
A number of smaller pipes feed into this line.
The southern portion of the site drains to Hamm Creek or directly to the Duwamish with the
exception of the West Marginal Way right of way which is directed in a ditch to the stormwater
main at S. 96 Street.
The County identifies an area adjacent to Hamm Creek as a regional sediment pond. Several smaller
stormwater pipes originating within the annexation area also drain directly to the Duwamish. Some of
these systems are privately owned and maintained. There are four commercial stormwater facilities
registered with the county within or immediately adjacent to the annexation area. These are owned by
the Sea King Industrial Park, Pacific Industrial Supplies, Beardsley Properties and the Arco Station.
The King County stormwater main that flows through the middle of the site serves a drainage basin of
approximately 120 acres. Most of that basin is in residential land use, but several highways are present
and there is an industrial area just west of the annexation area across West Marginal Way.
2.4 Contamination History
In 2001, the entire Lower Duwamish Waterway (LDW) was declared a Superfund Site due to high
levels of contamination, particularly polychlorinated biphenyls (PCBs) in the river sediments. In 2002,
the LDW was identified as a Model Toxics Control Act (MTCA) site by Washington Department of
Ecology (Ecology). EPA is overseeing the remedial activity at the LDW and Ecology is in charge of
source control. The chemicals of greatest concern are PCBs, polycyclic aromatic hydrocarbons (PAHs),
dioxins /furans, arsenic and other metals, and phthalates. Several early action areas were identified as
priority areas for cleanup, but the proposed annexation area was not one of these early action areas.
However, two portions of the LDW within the annexation area, one at S 96 St and one near S Director
St., have been identified as areas of greater concern based primarily on PCB levels in river sediments
that are above sediment quality standards. Ecology has two source control areas in the annexation
area. The northern portion is within the Sea King Industrial Park source control area and the southern
portion is in the West Restoration source control area. Neither has been considered a high priority area
for source control.
Under the Ecology source control program, a number of studies have been done within the LDW. In
2008 and 2009 sediment samples from storm drains and catch basins were analyzed. In the 96 Street
storm drain, levels of Zinc, PCBs, PAHs, Phthalates, 4- Methylphenol and Benzyl alcohol were found
above the sediment cleanup screening level (SCSL). At Hamm Creek levels of Zinc, Fouranthene,
Phthalates, 4- Methylphenol, and TPH (diesel and oil) were above the SCSL. No further sampling was
conducted in either of these locations in 2010. A study was also undertaken of sediment contamination

along the banks of the Duwamish throughout the LDW (Hart Crowser, 2012). In the Sea King source
control area some samples had levels of metals, PCBs and PAHs above the most stringent soil
screening levels, but none above the MTCA -B soil cleanup levels. In the West Restoration source
control area (Hamm Creek), there were some samples with levels of BTEX, metals and PAHs above
the most stringent soil screening levels, but again none above the MTCA -B soil cleanup levels.
There are currently five (5) Ecology MTCA clean -up sites listed within the annexation area or
immediately proximate to it. Three of these have no further action required and are in post cleanup
monitoring. Table 1 is a list of these sites.

3.0 STORMWATER SEDIMENT SAMPLING
PBS met with the City of Tukwila on June 26, 2012 to identify potential sampling locations. A total of 5
locations were identified. These were refined during sampling based on field conditions. Sampling
occurred on July 5, 2012. PBS collected sediment samples at each of the locations identified in Table
2. The sample locations are shown on Figure 2.
Samples were collected from the catch basin locations using a stainless steel scoop connected to an
extension pole to access the bottom of the 4 to 8 foot deep catch basins. The sediment samples
collected from the open drainage ditches and Hamm Creek were collected using a steel shovel to
obtain a sample from the top 1 to 3 inches below surface level. The shovel, scoop and extension pole
were decontaminated using an Aloconox® spray wash between each sample location. The sampler
donned a new pair of nitrile gloves between each sample.
The sediment samples were collected in laboratory- supplied unpreserved 8 -ounce glass jars, and 40 -ml
glass vials preserved with methanol, placed on ice in a cooler and transported to Fremont Analytical
Laboratories in Seattle, Washington, with chain -of- custody documentation. Analyses were conducted
under normal turnaround time. Soil samples were analyzed for total petroleum hydrocarbons for
gasoline, and diesel and heavy oil using methods NWTPH -Gx and NWTPH -Dx; Volatile Organic
Compounds using EPA Method 8260; Polyaromatic Hydrocarbons (PAHs) by EPA Method 8270(SIM);
Polychlorinated Biphenols (PCB) using EPA Method 8082, Total Metals by EPA Method 6020; and
Mercury using EPA Method 7471.

3.2 Results
Results from the sediment sampling are presented in Table 3 and compared to the Model Toxics
Control Act (MTCA) soil cleanup level A standards for industrial sites and the Washington State
Department of Ecology Sediment Cleanup Screening Levels (SCSL). All samples had levels of
methylene chloride, but this is attributed to the preservative used by the laboratory and is not
reflective of onsite contamination.
Sediments taken from both the roadside ditch (SS -3) near the intersection of South 96th St and West
Marginal Way; and the Hamm Creek culvert (SS -4) on the east side of West Marginal Way did not
have contamination levels above either MTCA -A or SCSL levels.
Two of the sampling sites had contaminant levels above the CSL. The ditch near the wrecking yard
(SS -5) had levels of silver above the SCSL and the main South 96 St storm (SS -2) pipe sediments
had zinc levels above the SCSL.
Two of the sample sites had contaminant levels above the MTCA -A industrial levels. The catch
basin on 15 Ave. S (SS -1) had levels of NWTP -Dx, PAHs and Cadmium above MTCA -A levels.
The main South 96 St storm (SS -2) had levels of arsenic and cadmium above MTCA -A levels.
A summary of the detected analytical results by constituent includes the following:
Petroleum as heavy oil was detected in 3 of the 5 samples (SS -1, SS -2 and SS -5), with SS -1
having the highest concentration of 2,270 mg /kg, which exceeds the MTCA Soil Cleanup Level
A industrial standards.
Metals (13- priority metals) were detected in each of the five samples. Sample SS -2 had the
highest overall individual metal concentrations, and SS -5 had the highest silver concentration.
Volatile Organic Compounds (VOCs) were not detected above laboratory reporting limits or
were detected at very low concentrations. VOCs do not appear to be of concern in the sediment
samples.
Polynuclear Aromatic Hydrocarbons (PAHs) were detected in each of the 5 samples. PAHs
concentrations were highest in SS -1, with individual concentrations above the MTCA -A levels.
Polychlorinated Biphenols (PCB) were not detected above laboratory reporting limits in the
samples.

4.0 DISCUSSION
Contaminants found in the stormwater system are either being generated from sources within the
annexation area (SS -1, SS -2 and SS -3) or carried down gradient from higher in the watershed (SS -2,
SS -4 and SS -5). While sediments might be carried into the S. 96 St pipe from the LDW during high
tides or high river flows, it is unlikely that these sediments would remain in the pipe for long because
flows during most of the year would be sufficient to flush them back out. During sampling, there was
two feet of water in the pipe.
The purpose of the testing was to determine if catch basin sediments should be considered as
petroleum contaminated soils or hazardous waste under Washington Department of Ecology (Ecology)
guidelines and to evaluate disposal options and re -use feasibility. The constituents of concern
encountered in our sampling are total petroleum hydrocarbons (TPH) as heavy oil, Polyaromatic
Hydrocarbons (PAHs), and the Resource Recovery and Conservation Act (RCRA) 13 priority metals
(antimony, arsenic, cadmium, chromium, copper, lead, mercury, nickel, silver and zinc). While PCBs
are a major concern throughout the LDW, they were not detected in this sampling.
4.1 Characterization of Contamination
As shown in Table 3 the TPH as heavy oil detected in the catch basin sediments ranged from <43.8 to
2,270 mg /kg. The Ecology MTCA soil cleanup level A for industrial sites is 2,000 mg /kg. Any sediment
with TPH above that level would be classified as petroleum contaminated soils and would require
treatment or landfill disposal. Additionally, the PAH concentrations detected in sediment samples
indicate that sediments contain petroleum compounds typically related to oil and grease. The
carcinogenic PAH concentrations detected in sample SS -1 exceed the MTCA soil cleanup level A for
industrial sites of 2 mg /kg. Based on the sample results, the detection of heavy oil /PAHs in the
sediment may classify the waste as a special solid waste containing petroleum. The waste may need to
be disposed of at licensed landfill facility.
As shown in Table 3, there were detected metal concentrations in select catch basin sediments that
exceed the MTCA -A or SCSL standards. To determine if samples should be classified as hazardous
waste under Ecology's Dangerous Waste Regulations (WAC 173 303 -071), the total metal
concentrations in mg /kg were compared to Toxicity Characteristic Leaching Procedure (TCLP)
regulatory levels. This TCLP practice involves dilution of samples by a factor of 20, with resulting TCLP
results being no greater than 1 /20 the total metals in sample. This practice is thought to establish a
more reasonable estimate of metal leaching in soil. Lead concentrations in sediment samples above
100 mg /kg could potentially exceed the TCLP level for lead (5 mg /L). The remaining metal
concentrations do not indicate levels that would be categorized by TCLP as hazardous waste.
Contaminant levels (particularly silver and zinc) above SCSL could trigger a source control action by
the Washington DOE. The source of the contamination is likely coming from private industries, but the
City may still be required to clean the contaminated pipes. A comparison of stormwater sediment metal
levels in the annexation area with King County stormwater sediment averages is presented in Table 4.
The comparison indicates that specific metal concentrations in catch basin sediments from the Triangle
Annexation Area (July 2012 Average Value) are generally greater than average levels in other
stormwater systems in King County. Arsenic in particular was considerably higher (64X) than the
average.

catch basin waste solids samples in King County (Herrera, 1995)
4.2 Disposal Options
The reuse of street sweepings and catch basin sediments is a highly effective way for municipalities to
be cost effective and environmentally responsible. However, there are state and federal regulations in
place that prohibit certain uses due to potential toxins that may exist within these sediments if
untreated. Specific concern goes to the RCRA 8 metals (arsenic, barium, cadmium, chromium, lead,
mercury, selenium, silver) and TPH levels (total petroleum hydrocarbons). Though most RCRA 8
metals occur naturally within the environment, they do have acutely adverse environment and human
health effects when found in above average concentrations.
TPH exposure is almost unavoidable in a society that relies heavily on petroleum products. Currently,
municipalities can landfill or store on site these materials; catch basin sediments go to drying beds and
sweepings to. a Department of Public Works lot or similar controlled runoff location.
According to Ecology Best Management Practices guideline:
"All street waste shall be given a visual and site evaluation for obvious contaminants and an
historical review for spills back to the date of the most recent cleaning. The waste site should be
sampled and tested for likely hazardous waste constituents or toxicity if contamination is suspected
or has been found at this site in the past. Disposal and use options of tested waste will be
determined by the test results and dangerous waste rules" (Ecology 1995).
If sediments are classified as non hazardous, reuse options are more open than if these sediments
were to be considered hazardous material. General guidelines for reuse should: include analytical
testing; remain 100 feet away from any wetland; remain 500 feet from any drinking water supply.
Disposal /reuse options, without additional testing, stated in much of the literature include:
"No action" Continued disposal of materials in landfills.
-Daily cover at lined /unlined landfills
Limited use compost additive
Containment/absorption material for hazardous material spills
Roadway fill or backfill
Sub -fill for potholes
Replacement for raw material in concrete or asphalt

For sediments that exceed the TPH testing, on -site remediation may be possible. The bacterial
decomposition that is associated with composting has been effective for reduction of contaminants.
Composting "achieves some biological decomposition of organics and some thermal desorption of
volatile organics. The process is relatively simple, involving windrows of material periodically wetted
and turned to enhance oxidation and biological activity. Inorganics are often blended with organics in
this process to prepare a suitable end product, usually topsoil or mulch." (Mathiesen, et. al., 1997)
Besides composting, biological additives for biological decomposition may be used to aid attenuation.
Biological degradation includes inoculating piles with soil bacteria, mycelial fungi, and nutrients. These
additives aid in "nutrient cycling, waste and residue decomposition, and detoxification of environmental
pollutants" (Sims, 1990). Finally, contaminants can be "immobilized" by including them as aggregates in
concrete or asphalt. It may be necessary for the Washington DOE to approve alternative uses of catch
basin solids.
5.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the limited sampling conducted and a review of past sediment sampling in this area,
sediments in the storm system do not appear to be highly contaminated and contamination levels are
generally reflective of urban areas. The contaminants of concern that have been identified are RCRA
priority metals (particularly arsenic, chromium, lead, silver and zinc), total petroleum hydrocarbons in
the heavy oil category, and PAHs. PAHs and TPHs appear to be originating within the annexation area,
while metals are coming from both within and above the annexation area. The highest levels of
contamination were found in the 15 Ave. S catch basin and the main S. 96 St pipe. Levels of
contamination in Hamm Creek and the ditch along West Marginal Way were all below thresholds so
sediment removal from these areas would have no restrictions. Sediments from the ditch by the
wrecking yard had elevated levels of several metals and disposal should either be at an approved
landfill or reused in a manner where the metals cannot leach out. Sediments removed from the S 96
St pipe and feeder pipes within the annexation area will need to go to an approved landfill or petroleum
contaminated waste site.
Cleaning of public storm drains that feed into the S 96 St. pipe is recommended. Periodic testing of
the sediments from the storm pipes within the annexation area is also recommended. Ongoing source
control actions by Ecology should help to reduce contaminants coming into the system.

I. SAMPLE RECEIPT:
All samples were received intact. The internal ice chest temperatures were measured on receipt and
are recorded on the attached Sample Receipt Checklist.
II. GENERAL REPORTING COMMENTS:
Results are reported on a wet weight basis unless dry- weight correction is denoted in the units field on
the analytical report "mg /kg -dry" or "ug /kg- dry").
Matrix Spike (MS) and MS Duplicate (MSD) samples are tested from an analytical batch of "like" matrix
to check for possible matrix effect. The MS and MSD will provide site specific matrix data only for those
samples which are spiked by the laboratory. The sample chosen for spike purposes may or may not
have been a sample submitted in this sample delivery group. The validity of the analytical procedures
for which data is reported in this analytical report is determined by the Laboratory Control Sample (LCS)
and the Method Blank (MB). The LCS and the MB are processed with the samples and the MS /MSD to
ensure method criteria are achieved throughout the entire analytical process.
III. ANALYSES AND EXCEPTIONS:
Exceptions associated with this report will be footnoted in the analytical results page(s) or the quality
control summary page(s) and /or noted below.

PUBLIC HEARING
a. Tukwila Potential Annexation Area (PAA) North Highline.
Jack Pace, Community Development Director, explained a request for annexation was received on May
17, 2012 from the property owners representing at least 10% of the assessed value of the proposed
annexation area. On May 21, 2012, the City Council accepted the 10% petition and authorized the
circulation of the 60% petition. On June 5, 2012, the property owners representing at least 60% of the
assessed value of the proposed annexation area (Tukwila's PAA) submitted their petition to commence
annexation proceedings. The King County Assessor validated the petition on June 7, 2012. On
June 11, 2012 the Council set the public hearing date for June 25, 2012.
Minnie Dhaliwal, Planning Supervisor, explained there are several property owners who signed the
petition in attendance this evening. Ms. Dhaliwal utilized a PowerPoint presentation to review the staff
analysis and informational memorandum in the agenda packet (pages 3 -11). Highlights of the
presentation included:
The Potential Annexation area is approximately 166 acres, consisting of 25 parcels
This area represents $97,616,700 in total assessed property value
A marina is part of the potential annexation with 18 live- aboard residents
This annexation involves the direct petition method
The impacts of the annexation on government services:
Potential revenue:
Utility tax
Storm Drainage
Sales and Property Tax
Business License and Revenue Generating Regulatory License fees
Potential expenses:

7:22 p.m. Council President Seal opened the Public Hearing.
Jamie Durkan, 22403 Sweeney Road, Maple Valley, stated he is representing the Desimone Trust. He
explained the Desimone family was contacted by City officials relating to the potential annexation of this
area into Tukwila. They are in favor of the annexation as they like working with the Tukwila City Council.
They do have some concerns with accepting Tukwila's MIC /H zoning for the proposed annexation area.
He explained the property owners currently operate a marina in this area, and the City's current zoning
does not list marinas. He said if the annexation moves forward, they will be requesting a letter of
interpretation allowing the marina to remain. Upon final annexation, they will follow up with a code
amendment request relating to marinas in the MIC /H zone.
7:24 p.m. Council President Seal closed the Public Hearing.
SPECIAL ISSUES
a. Tukwila Potential Annexation Area (PAA) North Highline.
If the City Council concurs with the annexation, staff will prepare an annexation packet for submission to
the King County Boundary Review Board (BRB). Analysis of how the proposed annexation complies with
the Growth Management Act, County Wide Planning Policies, and BRB review criteria (RCW 36.93.170)
is required to be submitted with the Notice of Intent to annex.
Councilmember Ekberg asked about the current King County zoning for the area and what non-
conforming uses would be inherited with the proposed annexation.
Ms. Dhaliwal explained the light industrial areas are similar to the City's current Comprehensive Plan
designation. There are special provisions in the Tukwila code relating to office establishments that were
established prior to 1995. The proposed annexation area is designated in the City's Comprehensive Plan
as MIC /H, and staff can research this issue if the Council so chooses. Comparing King County's and
Tukwila's zoning is like comparing apples to oranges due to the differences in the list of allowable uses
between the two codes. She clarified King County's current zoning generally allows the same type of
uses as Tukwila's MIC /H zoning.
Councilmember Robertson asked for clarification on the Fire Department information that is on page 6 of
the agenda packet relating to response times, and how the Fire Department would respond to a marina
fire. Additionally, he inquired whether the potential annexation area would increase the tax base for the
Tukwila Metropolitan Park District (MPD).
Nick Olivas, Fire Chief, explained Fire Department staff completed 2 trial runs to the proposed annexation
area from station quarters. During the trial runs, staff did not use sirens and they stopped at the stop
lights. After completing the 2 trial runs, it was determined an engine company in quarters could respond
to a call in 5 minutes. Recent discussions with staff on the best approach to respond to a marina fire
would be to use a portable pumper and request fire boat assistance from Seattle.

Tukwila City Council Committee of the Whole Minutes
June 25, 2012
Page 3 of 6
Peggy McCarthy, Finance Director, clarified staff previously made inquiries about the taxing authority of
the MPD in relation to the proposed annexation area. It is her understanding that an annexation area
would be subject to the property tax for the MPD; however, she will follow up on her original information
request and update the Council when she receives the information.
Councilmember Kruller asked if staff could include the City's MIC zoning map in future agenda packets.
Ms. Dhaliwal answered in the affirmative. Additionally, she inquired whether the proposed annexation
area along the Duwamish River consists of a Super Fund site and any other potential liabilities for the
City.
Ms. Dhaliwal said it is her understanding that the area is in proximity to the Lower Duwamish Waterway
clean -up location, and staff is in the process of doing additional review. Public Works staff has suggested
the City undertake testing within the storm drains to identify any potential stormwater runoff issues.
Mr. Pace stated that annexing the area into Tukwila does not eliminate the property owner's
responsibility. Staff has been reviewing the infrastructure that Tukwila would be responsible for, such as
roads and stormwater systems. Staff has met with the City Attorney, reviewed the current practices of
King County relating to the area, and had conversations with the Department of Ecology. The main
unknown at this time involves the stormwater issues.
Councilmember Robertson asked how the proposed annexation area would be affected by the City's
Shoreline Master Program.
Mr. Pace stated the current uses in the annexation area along the Duwamish River match the City's
Shoreline Master Program. The issues involve the current zoning versus the City's zoning code.
Council President Seal announced staff will conclude their research on the items listed in the
informational memorandum and return to a future Council meeting.
b. A contract for the Alive and Free Program.
Councilmember Quinn indicated this item was discussed at the Finance and Safety Committee meeting
on June 19, 2012. The committee members were unanimous in recommending approval.
Dennis McOmber, Police Commander, explained the Police Department and City Administration are
seeking Council approval to sign a Memorandum of Understanding with the Valley Cities for
implementation of the joint funding program known as "Alive and Free." In 2011, Tukwila Police staff met
with other valley police agencies to explore a gang violence prevention program. "A Better Seattle" (a
community relations program led by the Seattle Seahawks) and the YMCA of Greater Seattle Alive
Free have partnered with the City. The proposed program hires and trains "Street Outreach Workers" to
address youth gangs in south King County. The program is currently active in Seattle and used
effectively in Los Angeles, Baltimore, Chicago, and Washington DC.
The City's portion of this program totals $60,000, with half of it to be funded from "A Better Seattle," and
staff recommends the other half be funded from the City's Drug Forfeiture Accounts for 2012.
The Council exchanged comments and thanked staff for their work on this program.
COUNCIL CONSENSUS EXISTED TO FORWARD THIS ITEM TO THE NEXT REGULAR MEETING.
c. A resolution ratifying the amended and restated Cascade Water Alliance Interlocal Agreement.
Councilmember Robertson indicated this item was discussed at the Utilities Committee meetings on
May 15 and June 12, 2012. The committee members were unanimous in recommending approval.
Cascade Water Alliance (CWA) has requested to change from a Watershed Management Partnership to
a municipal corporation and become a Joint Municipal Utility Service Authority (JMUSA). Approval by
resolution is needed from each of CWA's 8 members. The Council is being asked to approve the draft
153
Tukwila City Council Committee of the Whole Minutes
June 25, 2012
Page 4 of 6
resolution which converts CWA into an authority under JMUSA and also converts the City's current
Interlocal Agreement into a Cascade Water Alliance Joint Municipal Utility Services Agreement.
Councilmember Robertson stated the Utilities Committee had questions relating to sections 4.7, "Budget,
Dues; Financial Management," And 9.2, "Withdrawals, in the proposed agreement. He asked staff to
clarify the costs associated with those two specific sections.
Pat Brodin, Public Works Operations Manager, introduced Chuck Clarke, Chief Executive Officer of
Cascade Water Alliance.
Mr. Clarke explained section 4.7, "Budget, Dues; Financial Management," was originally crafted when
CWA formed 13 years ago. The paragraph relating to dues (second paragraph of section 4.7) was based
on the assumption of rapid and extensive growth in the cities of Covington, Issaquah and Sammamish.
Due to this growth, those three cities would then be responsible for a higher share of CWA's
administrative costs. It was discovered that all member cities were paying 5% of CWA's administrative
costs, and those costs were not being charged to Covington, Issaquah and Sammamish. In 2011 the
CWA board requested an amendment to the current interlocal agreement to correct that issue, and to
raise the member cities dues from 5% to 9 Over the years, the administrative costs exceeded the
established 5% and an increase was necessary. The final result of the change in dues structure requires
all member cities to pay the 9% dues, rather than limiting dues to cities with water consumption. Section
9.2, "Withdrawals," clarifies that any member city that elects to withdraw from CWA will be responsible for
their share of the CWA bonds and administrative costs so as not to burden the remaining member cities.
The Council exchanged comments and asked clarifying questions of staff on the above topic.
COUNCIL_ CONSENSUS EXISTED TO FORWARD THIS ITEM TO THE NEXT REGULAR MEETING.
d. Tukwila Village library proposed deal terms.
Derek Speck, Economic Development Administrator, explained City Administration and King County
Library System (KCLS) have agreed on proposed deal terms for constructing a new library on the Tukwila
Village site. The Council is being asked to consider and approve the proposed deal terms at the Special
Meeting to follow the Committee of the Whole meeting.
Mr. Speck utilized a PowerPoint presentation to provide an overview of the proposed key deal terms with
the King County Library System. Highlights of the presentation included:
10,000 square foot library at a land price of $500,000.
Conceptual site plan approval by KCLS and Tukwila Village Development Associates, LLC to be
submitted within 45 days.
King County Library System will submit the building permit application within 10 months of
Tukwila Village Development Associates, LLC's submittal.
King County Library System and the City will close escrow after building permits are ready (or the
City can terminate the deal).
Construction will commence within 6 months of escrow (or the City may repurchase the property
at the current sale price).
Complete construction within 2 years of commencement (or the City may repurchase the property
at the current sale price).
Bill Ptacek, Director of King County Library System, stated they are very excited for progress on an
agreement, and KCLS has an architect that is ready to begin this week. KCLS is anxious to proceed with
construction of the new Tukwila Library. The KCLS Foundation Board recently toured the Tukwila Village
site, and they had a great presentation from Tukwila School District staff. He thanked the Council for their
support during this long process.
Jeanne Thorsen, King County Library System Foundation Executive Director, indicated the Foundation
has 30 board members who are excited to begin fundraising for the new Tukwila Library. She said the
Foundation will seek Council support and advice during the fundraising activities.
154

Page 5 of 6
Sharon Mann, 4452 South 160 Street, stated she is very happy to have the City and KCLS reach an
agreement for the new Tukwila Library at the Tukwila Village site. She thanked KCLS, City staff and the
Council for moving forward with the Tukwila Village vision.
Marie Parrish, 4430 South 150 Street, expressed her appreciation for the continued negotiation efforts
by the City Administrator and Economic Development Administrator.
The Councilmembers thanked Mr. Ptacek, Ms. Thorsen and City staff for continuing to work through the
issues associated with the project and voiced their support for moving forward with the construction of the
new 10,000- square -foot Tukwila Library.
Mr. Speck explained that if the Council approves the draft deal terms, the next step would be to have the
City Attorney begin drafting the final agreement in conjunction with the King County Library System.
Upon completion of the final agreement, staff would return to a future Council meeting for Council
approval.
COUNCIL CONSENSUS EXISTED TO FORWARD THIS ITEM TO THE SPECIAL MEETING THIS
