Cedar At The Highlands Critical Areas Review—Addendum
Otak Project No. 32847B
Addendum Proposal for Professional Services
March 1, 2018
The following scope of work and cost estimate was developed by Otak, Inc. (Otak) to
provide the City of Renton (City) with additional services associated with the Cedar at the
Highlands proposed project. Otak had previously prepared a review of the Revised Critical
Areas Study – “Cedars at the Highlands” Parcel #45750-0106 (Study) dated October 3, 2017 and
prepared by Sewall Wetland Consulting, Inc. (SWC) for proposed construction of a 14-lot
plat with associated infrastructure. The proposed project is located on Parcel #145750-
0110, off 160th Avenue SE in the City of Renton. Otak also reviewed additional support
documents, including a preliminary site plan for the proposed project and previously
prepared wetland delineation for a parcel to the north of Parcel #145750-0110.
Otak submitted the review of the Study, dated December 6 2017, to the City of Renton.
The Otak review recommended additional wetland delineation and characterization work to
be conducted on site, including modification of wetland rating scores and associated buffers.
Further characterization of two watercourses occurring on the subject property was also
recommended.
A technical memorandum, dated January 31 2018, was submitted to the City by Soundview
Consultants (SVC). The SVC memo presented information and interpretations that differed
from site conditions observed by Otak and SWC wetland scientists. This limited scope
includes a site visit/meeting to observe conditions on the subject property with the City,
SVC, and SWC. Based on the site visit, Otak will prepare a brief memo summarizing the
results of the visit and providing conclusions of on-site conditions.
Scope of Work
Task 1—Site Visit
In tandem with the City, SVC, and SWC Otak biologists will participate in a site visit to
observe and evaluate existing conditions on the site. Specifically, wetland delineations,
wetland ratings, and buffer dimensions and conditions will be evaluated and discussed,
potential project elements impacts will be examined, and functions provided by on-site and

adjacent wetlands, streams, and buffers will be field characterized as a component of the
meeting.
Assumptions:
• Two Otak biologists will attend the field meeting that will last up to two hours. If an
additional site visit is required for any reason, Otak will prepare a scope amendment for
the specific effort.
• Project area wetlands will not be delineated under this scope of work.
Task 2—Memorandum of Findings (Addendum)
Based on the field site meeting, Otak staff will prepare a brief memorandum that
summarizes results of the field meeting, as well as conclusions regarding site conditions and
consistency of the proposed project and environmental support documentation provided by
the applicant with the Renton Municipal Code.
This Memorandum will be provided in pdf format for City use.
Deliverables:
• Memorandum of Findings (Addendum)
Task 3—Project Coordination
This task will include general project management, development of the project approach, a
site meeting if necessary, and coordination with City staff.

Otak proposes to complete the above Scope of Work for a time and materials amount of
$1,500.00. In-house reimbursable expenses and any outsourced direct expenses (e.g.,
postage/deliveries, mileage, etc.) will be invoiced at cost plus 10% and are included in the
contract amount. This is a not-to-exceed scope of work; we will not exceed this budget
without prior approval from the City of Renton. If conditions are found to be different from
those described above, Otak will notify the City of Renton immediately to discuss any
impacts to the scope of work and budget
