penalties, expenses, attorney’s or attorneys’ fees, costs, and/or litigation expenses to or
by any and all persons or entities, arising from, resulting from, or related to the negligent

Renton, WA 98057
Attn: Amanda Free, Economic Development Director
Re: Proposed Scope of Services and Budget
Phase I Environmental Site Assessment Services
Stoneway Property
Renton, Washington
Dear Ms. Free:
Landau Associates, Inc. (Landau) is pleased to submit this proposed scope of services and budget to
assist the City of Renton (City) with Phase I environmental site assessment (ESA) services for King
County Parcel No. 1723059026 (subject property). Landau understands that the City is planning on
purchasing the subject property and has requested a Phase I ESA to evaluate conditions that could
present environmental liabilities to the City as the property owner.
BACKGROUND INFORMATION
The subject property consists of a 12.54-acre parcel that is commonly known as the Stoneway
Property and is located southwest of Cedar River Park, between the Cedar River and Maple Valley
Highway in Renton, Washington. The subject property is owned by SRMRENTON, LLC and currently
consists of vacant land and a container storage yard.
Landau conducted an environmental review of the subject property on May 30, 2025 that included
review of documents regarding previous environmental investigation and remediation that have been
completed at the subject property to assist the City in evaluating the current status of the subject
property with respect to environmental contamination, as well as potential environmental liabilities
associated with acquisition of the subject property. Landau identified one cleanup site listing for the
subject property on the Washington Department of Ecology (Ecology) What’s in My Neighborhood
database associated with the former operation of the subject property as a concrete plant. Ecology
has issued a No Further Action determination for the release in 2019, which is subject to the
conditions of an environmental covenant. The cleanup process was completed relatively recently
under Ecology’s purview and no major data gaps were identified; however, complete documentation
of compliance with the existing environmental covenant was not included in the available records.
Exhibit A
Proposal: City of Renton / Stoneway Property Phase I ESA Services
August 15, 2025
2 landauinc.com
Ecology records indicate that a periodic review will be completed for the cleanup site this year, as
required for sites with environmental covenants.
PROPOSED SCOPE OF SERVICES
To meet the City’s objectives for the project, Landau proposes a scope of services consisting of a
Phase I ESA conducted in accordance with the ASTM International (ASTM) Standard Practice for
Environmental Site Assessments: Phase I Environmental Site Assessment Process, E 1527-21 (as
applied in the State of Washington). The Phase I ESA will include a review of historical and regulatory
information, a site reconnaissance of the subject property, interviews, data evaluation, and reporting.
Landau will also contact the Ecology site manager and owner of the subject property to request
documentation of compliance with the environmental covenant.
The assessment will identify the presence of recognized environmental conditions (RECs), historical
recognized environmental conditions (hRECs), and controlled recognized environmental conditions
(cRECs) in accordance with the ASTM standard. Landau will also identify, as appropriate, other
findings that do not meet the definition for an REC and are outside of the ASTM standard but that
may warrant recognition by the user of the assessment. A draft report will be provided for review by
the City; a final report addressing the City’s comments, as appropriate, will be provided in electronic
format (Adobe® PDF) only.
Assumptions
Landau’s assumptions in preparing the scope for the Phase I ESA include the following:
x City will provide access and necessary rights-of-entry to the subject property.
x The City will return to Landau a completed copy of the User-Provided Information Request Form
within 5 days of authorization of this proposal. The form will be sent upon Landau’s receipt of
authorization to proceed.
x The City will provide access to individuals/owners/tenants familiar with historical operations at
the subject property.
x The City or City’s representative will provide copies of available environmental and geotechnical
documentation about the subject property, including previous investigations, surveys, or
reports, within 5 days of authorization of this proposal. Landau understands that several prior
assessments have already been provided during the completion of the recent environmental
review for the subject property.
x The state agency regulatory review for the Phase I ESA will be based on the subcontracted
database report. The need for acquisition and review of information from agency files, such as
files from Ecology that are not available online, will be assessed based on the results of the
database report review and conducted under a separate authorization.
x The scope of services herein does not include a title search or review for environmental liens or
activity and use limitations (AULs). To be compliant with the requirements of the ASTM Phase I
ESA standard, the report user is required to complete such a search, and Landau requests that
the City provide the results to Landau. At the City’s request, Landau can obtain such an
Proposal: City of Renton / Stoneway Property Phase I ESA Services
August 15, 2025

environmental lien and AUL search report covering the subject property for an additional fee of
$350 per parcel, plus applicable taxes. Alternatively, title reports (such as a commitment for title
insurance) provided by the City will be reviewed by Landau for information regarding AULs and
environmental liens.
x Elements not included in ASTM E 1527-21 (e.g., identification, sampling, and analysis of
asbestos, radon, lead paint, and/or lead in drinking water; identification of wetlands; regulatory
compliance; cultural and historic resources; indoor air quality and vapor intrusion, including the
potential presence of mold or other biological contaminants; industrial hygiene; health and
safety; ecological resources; and endangered species) are not included in Landau’s scope of
services unless discussed herein.
x Conditions at properties outside of the subject property may not be observable from the subject
property or from public access areas and, as a result, may not be identified during the site
reconnaissance.
x The draft report will need only minor revisions, requiring no more than 2 hours to produce the
final report.
x The handling charge for subcontractor costs is 12 percent and is included in Landau’s budget.
x Costs do not include a contingency amount for unanticipated out-of-scope activities.
SCHEDULE
Landau is prepared to begin work immediately upon receipt of written authorization to proceed and
anticipates the following schedule:
x Week 1: Project initiation including data collection and review
x Week 2: Site reconnaissance
x Weeks 3 through 4: Reporting and submittal of the draft Phase I ESA report.
The final report will be provided electronically (Adobe® PDF) within 1 week of receipt of comments
regarding the draft version.
PROJECT STAFF
Landau staff for this project will include Jamie Brewster, Project GIT, who will be responsible for
day-to-day management of the project and for reporting. Kathryn Hartley, Senior Associate, will
provide senior quality review of project deliverables. Jamie and Kathryn will be supported by other
Landau staff experienced with ESAs in Washington.
BUDGET
Landau proposes to provide the above-described services on a time-and-expense basis in accordance
with the attached Compensation Schedule, which is hereby made a part of this agreement, for an
estimated cost of $8,400, as detailed in the table below:

Task 1: Phase I ESA $8,400
TOTAL $8,400
If unforeseen conditions are encountered, Landau will bring these to the City’s attention and seek
modification to this scope and budget, as appropriate. Landau will not exceed the total cost for the
above-described services without prior authorization from the City.

Landau anticipates that the City will develop a consultant agreement consistent with other
agreements between the City and Landau to formalize the working relationship on this project. Please
let us know how we can assist you in that process.

Re: Proposed Scope of Services and Cost Estimate
Phase II Environmental Site Assessment Services
Stoneway Property
1915 SE Maple Valley Highway
Renton, Washington
Dear Ms. Free:
Landau Associates, Inc. (Landau) is pleased to submit this proposed scope of services and cost to assist
the City of Renton (City) with Phase II environmental site assessment (ESA) services for the property
located at 1915 SE Maple Valley Highway in Renton, Washington (Site). Landau understands that the
City is evaluating potential purchase of the Site in order to develop a park and is requesting a Phase II
ESA to evaluate the current subsurface conditions on the Site and potential impacts to the planned
use of the Site.
BACKGROUND INFORMATION
The Site, also referred to as the Stoneway Property, consists of one 12.5-acre parcel (King County
Parcel No. 172305-9026), which is owned by SRMRenton LLC. The Site is located north of the Cedar
River and adjacent to the southeast of the City’s Cedar River Park. The Site was previously developed
with a concrete batch plant operated by Stoneway Concrete. Based on available aerial imagery, the
northcentral portion of the Site is currently used for storing dumpsters and roll-off containers and the
remainder of the Site is vacant.
Landau conducted an environmental review of the subject property on May 30, 2025 that included
review of environmental investigation and remediation documents and publicly available information
provided by the Washington State Department of Ecology (Ecology). Ecology records indicate that
releases of petroleum products, arsenic, formaldehyde, and elevated (alkaline) pH were discovered at
the Site resulting from its operation as a concrete batch plant from the 1960s to the early 2000s. The
releases were reported to Ecology and the Site was listed on Ecology’s Confirmed and Suspected
Contaminated Sites List database under Facility/Site ID 62244377 and Cleanup Site ID 2121.

Cleanup actions implemented by Environmental Partners, Inc. (EPI) between 2007 and 2010 included
the excavation of contaminated soil for either on-site bioremediation and re-use as fill material or off-
site disposal. EPI indicated that a minor amount of high-pH material surrounding the four large
settling ponds on the south side of the Site could not be practically removed due to proximity to
Cedar River. The remaining pH-impacted soils were relatively deep and were neither exposed to the
surface nor in direct contact with surface water of the Cedar River. Although there is no established
groundwater cleanup standard for pH, the highest recorded pH level at the subject property (12.54)
exceeded the Resource Conservation and Recovery Act (RCRA) threshold for characteristic dangerous
waste (12.5). As a result, pH was considered a parameter of concern for water quality.
Quarterly groundwater monitoring was conducted by EPI from June 2009 through June 2010. By 2010,
the only remaining chemical of concern exceeding Ecology Model Toxics Control Act (MTCA) cleanup
levels or screening levels in groundwater at the Site was arsenic. While formaldehyde was not
detected above laboratory reporting limits in each of the sampled monitoring wells as of August 2010,
the laboratory analytical results for formaldehyde had laboratory reporting limits ranging from 1 to
1,000 micrograms per liter (μg/L) compared to the current MTCA Method B screening level of 0.55
μg/L, which is based on cancer risk.
Additional groundwater monitoring for pH, dissolved arsenic, and formaldehyde was conducted by EPI
and Farallon Consulting LLC between 2010 and 2024. Formaldehyde has not been included in
laboratory analyses since 2017. Concentrations of dissolved arsenic have been below background
levels since 2013, and pH has been between below the RCRA threshold for characteristic dangerous
waste since 2017.
Ecology issued a No Further Action (NFA) determination in 2019. Due to the presence of high pH soil
and groundwater in the southern portion of the Site and concentrations of arsenic in groundwater
exceeding the Site cleanup level, the NFA was conditioned on compliance with institutional controls
recorded in an environmental covenant and performance of confirmational groundwater monitoring.
In January of 2025, Ecology determined that groundwater monitoring could be discontinued but
requested that the monitoring wells be left in place pending Ecology’s completion of a 5 Year Review
of the Site. The 5 Year Review is required to evaluate compliance with the restrictive covenant and to
confirm that the site cleanup continues to provide protection of human health and the environment.
The review is anticipated to be completed by Ecology in October 2025.
The City has requested a Phase II ESA as part of the City’s pre-purchase due diligence. The scope of
work presented below is intended to evaluate current subsurface conditions at the Site and to address
data gaps identified in the environmental review completed by Landau in May 2025.
PROPOSED SCOPE OF SERVICES
The proposed scope of services includes a subsurface investigation, reporting and data evaluation,
and project management. This proposed scope of services is based both on information provided by
the City and on Landau’s understanding of the Site. Descriptions of each task are provided below.

Task 1: Subsurface Investigation
Task 1 includes the subsurface investigation; the elements required to complete this task are listed
below:
x Subsurface Investigation Work Plan: Landau will prepare a brief work plan consisting of a
drilling and sampling matrix table, a figure showing the proposed investigation locations, and a
plan for handling investigation derived waste. The plan will be submitted to Ecology for approval
in accordance with the restrictive covenant.
x Field Preparation: Landau will prepare a Site-specific health and safety plan and coordinate with
the City, Ecology, and subcontractors to determine the Site investigation schedule.
x Utility Locate: Prior to any subsurface activities, Landau will coordinate a public and private
utility locate to identify potential utility conflicts within the investigation area. Landau will
subcontract with a private utility locating company to identify conductible and non-conductible
utilities near the boring locations prior to drilling activities and to use ground-penetrating radar
to identify the boundaries of the four former settling ponds.
x Soil Borings: Landau will subcontract with a licensed drilling contractor to conduct up to 2 days
of drilling and sampling that will include advancing up to 9 soil borings at the Site to a maximum
depth of 15 feet (ft) below ground surface (bgs) using direct-push drilling technology. During
drilling, the subsurface soil will be screened for evidence of contamination using visual and
olfactory methods. Additionally, samples will be screened for volatile organic compounds using
a hand-held photoionization detector.
- One boring will be advanced in each of the four former large settling ponds on the south
side of the Site (LAI-1 through LAI-4). Soil samples will be collected from two intervals in
each boring at 1 to 2 ft bgs and 10 to 12 ft bgs. If field evidence of contamination is
observed during field screening, one of the samples will be collected from the impacted
interval in the place of the nearest of the intervals listed above.
- Three borings will be advanced to the east, north, and west of the former large settling
ponds (LAI-5 through LAI-7). Soil samples will be collected from depths of 2 ft, 8 ft, and 15 ft
bgs. If field screening indicates evidence of contamination, one of the three samples will be
collected from the impacted interval in the place of the nearest of the intervals listed above.
- Two borings will be advanced on the west and east sides of the Site (LAI-8 and LAI-9), within
and downgradient of the formaldehyde cleanup area. Soil samples for laboratory analysis
will not be collected from these borings.
x Groundwater Sampling: Following collection of soil samples for field-screening from LAI-8 and
LAI-9, the licensed driller will install a temporary well at each of the two borings and purge
groundwater until it clears or until directed to stop by Landau staff. Groundwater parameters
(pH, temperature, specific conductivity, oxidation reduction potential, and dissolved oxygen) will
then be measured and one groundwater sample will be collected from each temporary well
using low-flow sampling techniques.
Landau staff will access each of the six existing monitoring wells, collect water levels, and purge
groundwater until it clears. Groundwater parameters (pH, temperature, specific conductivity,
oxidation reduction potential, and dissolved oxygen) will then be measured, and one

groundwater sample will be collected from each monitoring well using low-flow sampling
techniques. One blind field duplicate will be collected.
x Laboratory Analysis: Landau will submit soil and groundwater samples for laboratory analysis to
determine contaminant concentrations at the Site. For the purposes of cost estimating, Landau
has assumed that up to 17 soil samples and 9 groundwater samples will be collected for the
following analyses:
The 8 soil samples collected from LAI-1 through LAI-4 will be submitted for the following
analyses:
- Total petroleum hydrocarbons (TPHs) in the diesel and oil ranges (TPH-D and TPH-O,
respectively) by the Northwest TPH diesel-range extended (NWTPH-Dx) method.
- TPH in the gasoline range (TPH-G) by the Northwest TPH gasoline-range extended
(NWTPH-Gx) method.
- MTCA 5 metals (arsenic, cadmium, chromium, lead, and mercury) by US Environmental
Protection Agency (EPA) Method 6020/200.8.
- Semivolatile organic compounds by EPA Method 8270E selected ion monitoring
- pH by EPA Method 150.2.
The 9 soil samples collected from LAI-5 through LAI-7 will be submitted for the following
analyses:
- pH by EPA Method 150.2
The 2 groundwater samples collected from LAI-8 and LAI-9 will be submitted for the following
analyses:
- Formaldehyde by National Council for Air and Stream Improvement, Inc. (NCASI) 98.011
The 7 groundwater samples (including one field duplicate) collected from the existing
monitoring wells will be submitted for the following analyses:
- TPH-D and TPH-O by the NWTPH-Dx method with and without silica gel cleanup methods.
- TPH-G by the NWTPH-Gx method.
- Dissolved MTCA 5 metals by US Environmental Protection Agency (EPA) Method
6020/200.8. The samples will be field-filtered.
- Formaldehyde by NCASI 98.01
Samples will be placed in laboratory-provided sample containers and delivered to an accredited
analytical laboratory in a chilled cooler under standard chain-of-custody procedures for
chemical analysis.
1 ALS Global’ s laboratory in Kelso, Washington is currently the only laboratory certified by Ecology for analysis of
formaldehyde in water. The lab is only able to report down to a concentration of 200 μg/L. The current Method B
screening level for formaldehyde is 0.55 μg/L. Landau is researching additional options for analysis of
formaldehyde.

x Investigation-Derived Waste (IDW) Management Characterization and Disposal: Soil and water
IDW generated during drilling will be placed in drums and stored onsite pending the results of
the disposal characterization analysis. One composite soil sample of the drill cuttings from all
exploration locations will be collected for IDW soil disposal profiling. The composite soil sample
will be analyzed for NWTPH-Dx, pH, and RCRA 8 metals, plus copper, nickel, and zinc. One water
sample of the purge and decontamination water will be collected for IDW water profiling. The
water sample will be analyzed for NWTPH-Dx, pH, and RCRA 8 metals. Upon receipt of the
sampling results, Landau will coordinate with a local disposal company to transport the drums to
an appropriately permitted disposal facility. The proposed budget assumes IDW will be profiled
as nonregulated waste, and it includes costs to dispose of one 55-gallon drum of soil and one
55-gallon drum of water (purged and decontamination water).
Task 2: Reporting and Data Evaluation
Following receipt of field data and laboratory analytical results, Landau will conduct a review of the
analytical data for quality control/quality assurance purposes, tabulate the data, and compare the
results to applicable regulatory criteria. The analytical data and investigation findings will be
presented electronically (Adobe® PDF) in a technical memorandum, which will include a summary of
the investigation activities and sampling methods, data tables, and figures.
A draft of the technical memorandum will be submitted for review by the City. The budget for this
task includes the incorporation of one consolidated set of edits to the memorandum followed by
preparation of the final document. If additional investigation or cleanup activities are necessary, this
work would be conducted under a separate scope.
Task 3: Project Administration and Communications
This task will include overall coordination, contracting, management, and administration of the
project, including coordination and communications with the City and contractors and project billing.
This task will also include communications with Ecology to provide notification of the intended project
scope per the conditions included in the restrictive covenant.
Assumptions
For the purpose of estimating costs, the following assumptions were made:
x The City will provide access and any necessary rights-of-entry to the Site and to all sampling
locations at the time of the environmental investigation, including pursuing an access
agreement with the current Site owners.
x Communications with Ecology will require no more than 2 hours at the Senior Associate level.
x Drilling field activities, including the private utility locate, the advancement of eight soil borings,
and the collection of soil and groundwater samples, can be completed in two 12-hours day by
one Landau Project geologist or engineer and one Landau staff geologist or engineer, including
round-trip travel time and laboratory sample drop off. A third trip to the Site will be needed
prior to sampling to mark the proposed boring locations ahead of the public utility locate.

x The analytical laboratory estimate assumes that all analyses will be requested with a standard
turnaround time. Additional expedited analysis is available upon request for an additional fee,
which is described below.
x The existing groundwater monitoring wells are in good condition and will not need to be
redeveloped prior to sampling.
x The City will provide information regarding the locations of any non-conductible underground
utilities (e.g., concrete or plastic piping) or other known buried infrastructure at the Site.
Non-conductible utilities and other infrastructure are not typically identifiable using
conventional radio detection utility locating equipment. Landau is not liable for damage to any
underground utilities not identified by the City to Landau or not detected by the underground
utility locate service.
x The waste generated during field activities will be properly drummed, labeled, and stored at a
secured location at the Site selected by the City while Landau arranges for appropriate disposal.
Costs for offsite disposal as nonregulated waste are included in the proposed budget for this
project. If analytical results determine that the waste does not qualify as nonregulated, Landau
will discuss with the City an amendment to the budget for appropriate disposal costs.
x The City will provide IDW manifest authorization for disposal of IDW. Landau will not need to be
at the Site for IDW pickup.
x The City will provide one consolidated set of edits to the technical memorandum. It is assumed
that comments from the City will require no more than 2 hours of Landau staff time to address.
x Costs do not include a contingency amount for unanticipated out-of-scope activities by Landau
or subcontractors.
x The subcontractor markup for all tasks is 12 percent and is included in the proposed budget.
SCHEDULE
Landau is prepared to commence work under this scope of services immediately upon receipt of
written authorization to proceed. We anticipate that the field investigation could be completed within
2 weeks of authorization, subject to subcontractor availability. Soil and groundwater samples will be
submitted to the laboratory on a standard turnaround time of 10 business days. An expedited
turnaround time of 5 business days is available for an additional fee. The technical memorandum will
be prepared within 2 weeks following Landau’s receipt and analysis of the final laboratory analytical
reports. The final memorandum will be issued within 5 business days following receipt of comments
on the draft.
