Project: Phase I Archaeological Survey of the Proposed Storm and Sanitary Sewer Improvements in
Waterloo, Iowa
Tallgrass Archaeology LLC can complete this project for a total of $15,678.68. The total shall not exceed this cost within
the scope of work described below.
Scope of Work:
Phase I Archaeological Survey: Tallgrass Archaeology LLC proposes to complete a Phase I intensive archaeological survey
of the approximately 15.2-acre (6.1 hectare) project area in north Waterloo, Iowa. The project area is a roughly 20-meter
wide corridor extending for approximately 1.7 miles along W Airline Hwy, Airport Blvd, agricultural fields, lawns, and
fallow areas (see attached project plan map). Modern aerial photographs show the project corridor to be mixed use,
suggesting variable ground surface visibility throughout.
The Phase I will consist of the pedestrian survey at graduated intervals of the high ground surface visibility portions of the
project area and systematic subsurface testing at 15-meter intervals to examine the archaeological potential across the low
ground surface visibility portions of the project area. If any archaeological sites are encountered, then subsurface testing
will be conducted at 10-meter or less intervals at that location, as per the guidelines for Phase I testing of sites as approved
by the Association of Iowa Archaeologists (AIA). Any archaeological sites discovered will be evaluated for potential
eligibility under the integrity considerations and significance criteria of the National Register of Historic Places. All
subsurface tests will be backfilled upon completion, and an effort will be made to return the ground surface to its original
condition following subsurface testing. The results of the Phase I investigation will be summarized in a report that adheres
to the AIA guidelines for Phase I investigations.
Cost Assumptions and Requirements:
1. The size of the finalized project area will not exceed the 15.2-acre (6.1 hectare) project area pictured on the attached
project plan map. If additional survey area is needed, Tallgrass reserved the right to adjust its scope of work and
cost estimate as necessary.
2. If necessary, access to private property will be obtained by the City of Waterloo prior to fieldwork.
Additional Services
Any professional service not included or mentioned in this agreement are considered additional services. Additional
services, if approved or requested by City of Waterloo will be performed at the hourly rate utilized by this budget, available
upon request.
Billing:
City of Waterloo will compensate Tallgrass Archaeology LLC for the total lump sum price of the Phase I Survey within 30
days of the completion of the Phase I report.
