SUMMARY: This was the first site visit for The Other Side Village Phase 2 VCP Site. The goal
of the visit was to walk the area and identify site conditions prior to developing a site
characterization workplan. At the time of the visit, the Voluntary Cleanup Agreement was still
waiting for signature.
Phase 2 is located adjacent to the VCP site Redwood Road Dump #121 and is within the boundaries
of the Redwood Road Dump CERCLA facility that operated from 1923 to 1962. The extent of
landfill material and potential impacts on the site is unclear.

Currently vacant, the land includes a staging area (south end of Phase 2) used to store soil,
landscaping, and equipment for Phase 1. An old rail line owned by Union Pacific Railroad (UPRR)
is located between the VCP boundary and Indiana Avenue. The tracks have been removed and
TOSA plans to coordinate with UPRR for access due to site development plans.

In the late 1970s, the landfill was bisected by the construction of Interstate 215, creating a west
and east pile. It is unclear how much of Phase 2 will intersect with the east pile, but the surveyed
property line (marked with stakes) lies at the bottom of the main elevated area (assumed to be the
east pile). Much of the land is vegetated with tall grasses. Construction and demolition (C&D)
debris (e.g., concrete, asphalt, rebar) was observed throughout the area, with heavier debris
observed further to the west. Some of the soil from Phase I that did not meet geotechnical purposes
but was sampled to meet residential screening levels has been placed along the slopes of the main
elevated pile. The soil is lighter in color and was observed to be mixed with other debris such as
C&D and large tires. Based on the staked survey line, the hill and sloped surface are outside of the
Phase 2 VCP boundary.

Several hummocks containing unknown material are present to the north, and many of these
hummocks are vegetated. Previous DERR investigations for the Redwood Road Dump CERCLIS
Facility indicate that open dumping was practiced during landfill operation, with little information
on waste disposal practices. Salt Lake City Parks and Public Lands operates to the north and has
used a portion of the site to store yard waste, tree trunks, and mulch/wood chippings. Additional
debris (beyond C&D debris) was observed in the area, including a bridge, a light post, and an old
greenhouse building.

Water was observed in the north ditch; its source (flowing or stagnant groundwater) is unknown.
An outlet pipe is believed to be at the ditch's end but wasn't located during the visit due to the
water. The land levels out with fewer hummocks closer to the Phase 1 area.

A follow-up meeting is scheduled to compare notes and discuss next steps.

Photo 3: Looking west to I-215 (part of Phase 2). C&D observed in the distance.

Photo 4: Closer view of C&D to the west. Rebar appears to be buried.

Photo 5: Stake marking the property boundary for Phase 2. The stake is located at the beginning
of the elevated area (assumed to be the east pile). To the right is unknown landfill debris (not
part of the staging area). The phase I staging area is located at the top of the image with the first
homes in Phase I in the top left corner.

Photo 6: Material from phase one (lighter soil) that did not meet geotechnical purposes but met
the Residential RSL has been placed along the slope of the east elevated mound. Stakes marking
the VCP boundary for phase 2 are located at the bottom of the slope.
