Introduction
TREMAINE & ASSOCIATES is
a woman-owned business, established in 1994, and headquartered in West
Sacramento, California. Our services
include all aspects of conventional cultural resources management:
feasibility studies, management plans, archaeological reconnaissance,
site testing,
mitigation, and monitoring. By integrating a geophysics component,
we are also able to offer our clients more innovative strategies for
practical and regulatory problems. Our work is well researched, objective,
and
intended
to facilitate projects by implementing more effective approaches. TREMAINE
has a permanent staff that includes archaeologists, geophysicists,
graphic artists, GIS specialists, an office manager, a finance
manager and numerous field and laboratory technicians.
TREMAINE has
successfully completed a wide range of projects, from small-scale,
local land development
to highly complex
and demanding programs
in the sectors of communications (fiber optics), civil engineering,
transportation, water resources, and military facilities. Much of
our work in California
has been located in the Central Valley, Sierra Mountains, and North
Coast Ranges. With over 300 projects behind us, our senior
officers are each solid veterans of the resource management profession. Together
they
possess the complementary
strengths of managerial excellence, regulatory knowledge, academic
scholarship, and technical proficiency needed for project development
in Sacramento.
Further, TREMAINE retains a pool of experienced
archaeological technicians, some permanent full-time, and others
seasonal or on-call, as demand merits.
Approach to Projects
There are two aspects of projects involving cultural resources management:
(1) the legal aspect for compliance with both CEQA and NEPA; and (2) the
heritage tourism aspect. Both will be addressed in the following sections.
Legal Compliance
TREMAINE & ASSOCIATES has
worked on numerous CEQA, and Section 106 projects preparing reports for Initial
Studies, Environmental Impact Reports, Environmental
Impact Statements, and subsequent mitigation studies. For these projects,
we have conducted archival research, consulted with Native Americans
and local historical societies, evaluated resources for eligibility
to the California
Register and NRHP, monitored during construction in sensitive areas,
dealt with unanticipated discoveries, data recovery and Native American
concerns.
The Office of Historic Preservation has begun paying close attention
to the vertical Area-of-Potential-Effects (APE), taking into account
impacts in 3-dimensions. It is now necessary to reasonably demonstrate
that no subsurface
resources are located within the APE or Area of Direct-Impact (ADI).
Thus, it is assumed that surface surveys will be insufficient in and
of themselves. A discussion of the late quaternary geology of the region
and likelihood
of buried resources is now required. If the likelihood exists and vertical
impacts are significant or substantial, a subsurface investigation
may be
necessary. This can be accomplished using non-invasive geophysics,
augering, or backhoe trenching. TREMAINE is capable
of conducting all such subsurface identification work.
Conventional
Capabilities
The
TREMAINE office and lab facility
is a 10,600 square foot complex equipped with 13 networked computer
stations, and a research
library with
thousands of references. We maintain a large artifact processing and
analysis area, and the necessary excavation equipment capable of meeting
the needs
of multiple concurrent field operations. Our administrative support
services include an automated project budget and payroll tracking that
make project
management clear and organized. TREMAINE also has
a complete computer graphics, certified GIS and mapping department,
with staff experienced in a wide variety
of GIS software (e.g., ESRI ArcGIS, Spatial Analyst, 3D Analyst) for
producing comprehensive maps and detailed spatial analysis.
Our firm is well versed in handling a wide range of cultural
resource types associated with a variety of geographic settings and
temporal periods. Prehistoric work spans the last 10,000 years, including:
habitation
sites,
burial grounds, sparse lithic scatters, baked clay scatters, bedrock
milling stations, toolstone quarries, and seasonal encampments. Historic
work spans
the early 19th through early 20th century, ranging from contexts
associated with mission life, mining, ranching, logging, transportation,
as well
as urban residential and commercial settings. We are also able to
handle historic
architectural work through our subconsultant, Carol Roland, Ph.D.,
of Roland-Nawi Associates.
Geophysical Capabilities
Cultural resources can be obscured by vegetation,
pavement, or overburden, and therefore missed during conventional pedestrian
survey. We offer
a solution to this problem in an effort to avoid costly delays during
construction, when “unanticipated discoveries” are often made.
There are also advantages in using geophysics at the evaluation and data
recovery
phases of site management. TREMAINE uses a suite of geophysical instruments
as listed below.
- Mobile EM3
TREMAINE (with Argus
Technologies) has developed the
EM3, a mobile geophysical instrument for near-surface (upper
10 meters) electromagnetic
investigations. Both apparent conductivity and magnetic susceptibility
data are acquired for three volumes/depths simultaneously, resulting
in a tremendous increase in data, consequently greater confidence
regarding subsurface conditions. This information is useful for identifying
buried
cultural resources. However, it is also very useful within a number
of decision making arenas of project development, particularly, design
engineering,
geotechnical, environmental, and ROW/utilities. By identifying potential
problems during the planning and design phase, rather than down the
road, the “unforeseen” is avoided, reducing design errors and
omissions, schedule slippage, scope creep, and cost overruns. It
can also be used
as a fact-based audit of the project area's subsurface environment
(part of a project constructability review). Our technology has enormous
potential
for payoffs, given that currently, over 50% of all construction claims
and change orders are the result of insufficient subsurface information.
- Resistivity/Induced Polarization & Ground
Penetrating Radar
TREMAINE uses additional geophysical methods in conjunction
with the EM3 to characterize the subsurface environment as accurately
as possible. These methods are generally employed subsequent to the
EM3 survey
to better delineate those potential cultural resources or unforeseen
obstacles found
with the EM3. These methods are also used where site and/or soil
conditions are not conducive to obtaining good EM results, allowing
TREMAINE to
conduct surveys in a wide range of environments. The complementary
nature of the
resistivity data allows for more accurate models of the subsurface
to be generated from the EM3 data, reducing the need for more
expensive subsurface testing. Ground penetrating radar is now a commonly
used
technique in geotechnical,
engineering and ROW/utilities investigations for providing high resolution
images of the buried strata and objects. The combined use of these
different methods provides a powerful “toolbox” for cultural
resource, environmental, geotechnical and ROW/utilities investigations.
Heritage Tourism
Executive Order: Preserve America, signed by George W. Bush on March 3,
2003, calls for the “use of historic properties for heritage tourism
and related economic development in a manner that contributes to the
long-term preservation and productive use of those properties.” As
defined in the Executive Order, Section 7, “heritage tourism” “means
the business and practice of attracting and accommodating visitors
to a place or area based especially on the unique or special aspects of the
locale’s
history, landscape, and culture.” Furthermore, the National Endowment
for the Humanities has started a fairly new Initiative called We-the-People
showcasing America's Historic Places … that is, those that embody our
unique spirit, character and identity. The goals of the initiative
include a greater shared knowledge about the Nation's past, strengthened
regional
identities and local pride, increased local participation in preserving
the country's cultural and natural heritage assets, and support for the economic
vitality of our communities.
Archaeology has a charisma that other
aspects of historic preservation
sometimes lack. The process of discovery excites and interests many
people who are otherwise indifferent to or even hostile to history
and historic preservation. It is our strong contention that Sacramento’s history
can be brought alive and contribute to a project’s overall success
through interpretive displays and literature.
