Seattle Sounders FC Inadvertent Discovery Plan 1
INTRODUCTION
The Seattle Sounders FC are planning to develop a Performance Center at Longacres Office Park (LOP)
in Renton, King County, Washington in Township 23, Range 4, and portions of Sections 24 and 25.
Unico Properties LLC submitted an application for SEPA/CUP on behalf of the Seattle Sounders FC. The
Department of Archaeology and Historic Preservation (DAHP) determined that a cultural resources
assessment would not be required for the project but that an Inadvertent Discovery Plan (IDP) for cultural
resources should be prepared by a professional archaeologist. Unico Properties LLC contracted ASM
Affiliates, Inc. (ASM) to prepare the following Inadvertent Archaeological and Historic Resources
Discovery Plan for the Sounders FC Center at Longacres Project.
PROJECT DESCRIPTION
The Sounders FC Center at Longacres project is approximately 30 acres. It will consist of the use of a
portion of an existing office building for Sounders FC office space and indoor training facilities and
associated activities, outdoor recreation facilities including four full-size soccer fields, a Goal Keepers
Field, and accessory structures, and reconfiguration of an existing surface parking lot. Within the field
complex, light poles and a maintenance out-building will be erected. The new fields will have fences
surrounding them.

EXPECTATIONS FOR CULTURAL RESOURCES
Based on SEPA consultation with DAHP, the Project will not likely adversely impact important cultural
resources. However, DAHP requested the preparation of an IDP in the unlikely event that the ground-
disturbing activity associated with the project does encounter cultural resources.
Although no precontact archaeological sites are documented in the immediate vicinity of the Seattle
Sounders FC Project, the project area is within an area containing a high probability for cultural resources
based on the DAHP Predictive Model. Eight previously recorded archaeological sites are within one mile
of the project area: KI6, KI206, KI267, KI730, KI768, KI1132, KI1254, KI1558. Of the eight, two are
precontact (KI267 and KI6), one is protohistoric (KI1558), and the rest are historic. KI6 includes human
remains and is the only cemetery within one mile of the project area.
Two previous cultural resource surveys were conducted overlapping with Longacres Park: Roedel et al.
2004 and Rooke 2012. Roedel et al. 2004 conducted an impacts analysis of the area and concluded that its
project area did have a high probability of encountering precontact cultural resources. Rooke 2012
conducted a historic building inventory and concluded that no Historic Properties were eligible for listing
in the National Register of Historic Places (NRHP). The site has been redeveloped at least three different
times: first for farming, then as the Longacres horse racetrack (1933-1992), and finally as Boeing
Headquarters and Campus (Becker 2005). The development of Boeing Longacres Campus did not find
any potential archaeological evidence.
Longacres Park was not included in the State or National Registers of Historic Places (NRHP) because
the collective alterations to the site were too great to meet the integrity criteria (Ryan and Bowen 1993;
Hansen 1993). The James Nelson House is 0.4 miles west of the project area and is listed in the NRHP.
Ethnographically documented Native American villages and activity areas are recorded in the general
locality of the project area (Bagley 1916; Hilbert et al. 2001; Thrush 2007; Waterman 1922). The project
area’s proximity to the Duwamish River suggests that the area may have been used for hunting, fishing,
and gathering activities by native populations. Cultural resources associated with these activities could
include flaked stone artifacts including projectile points (“arrowheads”) and lithic debris from tool
manufacture (Figure 2), ground stone implements, animal bones, and cooking stones. Cooking stones (fire
modified rock) typically consist of cracked and/or broken cobbles with black and/or orange staining and
are often encountered within discrete concentrations potentially representing fire hearth features (Figure
3). While shell midden was found at KI6 (0.73 mi west of the project area), KI6 is within 70 ft of the
shoreline of the Duwamish River and the current project area is approximately 0.5 mi from the River.
Accordingly, shell midden is less likely to be found within the project area.
Historic debris associated with the early occupation of the project area could include farm equipment, old
bottles (Figure 4), ceramic fragments, pieces of metal, and bricks (Figure 5) associated with the racetrack,
most likely dating from the early to the mid-twentieth century.

INADVERTENT DISCOVERY PLAN
The following sections detail the procedures to be followed in the event that construction activities
associated with the Sounders FC Center at Longacres project inadvertently encounter cultural resources
and/or human remains.
INADVERTENT DISCOVERY OF CULTURAL RESOURCES PROTOCOL
Prior to commencement of project activities, construction personnel will be prepared for the possibility of
encountering prehistoric and/or historic archaeological materials during ground-disturbing activities. A
copy of this IDP will be kept onsite at all times during construction activities. The project proponent will
be responsible for contacting DAHP in the event of an inadvertent discovery.
In the event that construction activities associated with the Project encounter any cultural materials (e.g.,
bones, shell, stone tools, beads, ceramics, old bottles, hearths, etc.), including archaeological artifacts,
and/or sites, all work in the immediate vicinity will halt and DAHP, the affected Native American Tribes,
and a professional archaeologist will coordinate the treatment of the materials. Work shall not proceed in
the area of discovery until notification to proceed is granted by DAHP. Compliance with all applicable
laws pertaining to archaeological resources (RCW 27.53, 27.44 and WAC 25-48) is required. Failure to
comply with this requirement could result in criminal or civil penalties. The legal protection of
archaeological sites and cultural resources is covered under Washington State law (RCW Chapter 27.53).
If potential cultural resources are encountered during construction excavation, the project proponent shall
ensure that the following procedures are followed:
• Secure the location of the discovery immediately by halting all ground-disturbing activity;
• All ground disturbing activity that may further impact the resource must be halted or redirected;
• Secure all spoils piles and/or trucks that might contain cultural materials from the location;
• Record general information concerning the discovery, including the time, date, location, depth,
and discovery method of the material.
The project proponent will be responsible for contacting DAHP, a professional archaeologist, and the
affected Native American Tribes in the event of an inadvertent discovery of cultural resources.
The individuals and representatives of these agencies will coordinate an on-site meeting to determine if
the discovery represents cultural resource material and, if so, to ascertain the nature of the find. The
treatment of the cultural resources will be determined through coordination and consultation with these
agencies/individuals at that time.

INADVERTENT DISCOVERY OF HUMAN REMAINS PROTOCOL
If ground disturbing activities encounter human skeletal remains during the course of construction, then
all activity will cease that may cause further disturbance to those remains. The area of the find will be
secured and protected from further disturbance. The finding of human skeletal remains will be reported to
the county medical examiner/coroner and local law enforcement in the most expeditious manner possible.
The remains will not be touched, moved, or further disturbed. The county medical examiner/coroner will
assume jurisdiction over the human skeletal remains and make a determination of whether those remains
are forensic or non-forensic. If the county medical examiner/coroner determines the remains are non-
forensic, then they will report that finding to the Department of Archaeology and Historic Preservation
(DAHP) who will then take jurisdiction over the remains. The DAHP will notify any appropriate
cemeteries and all affected tribes of the find. The State Physical Anthropologist will make a determination
of whether the remains are Indian or Non-Indian and report that finding to any appropriate cemeteries and
the affected tribes. The DAHP will then handle all consultation with the affected parties as to the future
preservation, excavation, and disposition of the remains.
