Camp Ripley Cold War Phase II

SCOPE OF WORK PHASE II EVALUATION OF THE LATE PERIOD (1961-1989) COLD WAR ERA BUILDINGS AT CAMP RIPLEY, MORRISON COUNTY, MINNESOTA ? 1.00 INTRODUCTION 1.01 The Contractor will undertake a Phase II evaluation of the National Register of Historic Places eligibility of 86 late period Cold War Era buildings located at Camp Ripley in Morrison County, Minnesota (Figure 1). These Cold War Era buildings, which date from 1961 to 1989, will reach age 50 by the year 2039. The Cold War Era buildings dating from 1946 to 1961 at Camp Ripley are not included in this contract as they have been previously evaluated for eligibility to the National Register. 1.02 This cultural resources investigation partially fulfills the obligations of the Minnesota Army National Guard (MNARNG) regarding cultural resources, as set forth in the National Historic Preservation Act of 1966 (Public Law [PL] 89-665), as amended; the National Environmental Policy Act of 1969 (PL 91-190); the Archeological and Historical Preservation Act of 1974 (PL 93-291); the Advisory Council on Historic Preservation's regulation for the Protection of Historic Properties (36 CFR Part 800), and applicable State of Minnesota laws and regulations. 1.03 This cultural resources investigation will serve several functions. The report will be a planning tool to aid the MNARNG at Camp Ripley in meeting their obligations to preserve and protect our cultural heritage. It will be a comprehensive, scholarly document that not only fulfills federal and state mandated requirements, but also serves as a reference for future professional studies. It will identify resources that are eligible for listing on the National Register of Historic Places. Thus, the report must be analytical, not just descriptive. 2.00 PROJECT DESCRIPTION 2.01 Camp Ripley is located in central Minnesota with the Mississippi River as its eastern boundary and the Crow Wing River as its northern boundary (Figure 1). It encompasses parts or all of Rosing, Rail Prairie, Clough, Darling, and Green Prairie townships of Morrison County. Camp Ripley is the primary training area for the Minnesota Army National Guard. 2.02 There are 86 buildings at Camp Ripley in Morrison County, Minnesota, dating to the late period (1961-1989) of the Cold War Era. The Environmental Office and the Facilities Management Office at Camp Ripley are requesting evaluation of the National Register of Historic Places eligibility of these buildings to aid in future maintenance of the buildings and in the planning of future training activities at the camp. 2.03 Sixty-five (65) of these late period Cold War Era buildings are in the Camp's cantonment area and twenty-two (22) are in the Camp's range training areas (Figures 2 and 3). Table 1 lists these buildings, with the first two digits of the facility number indicating the area within the Camp's cantonment area or the training area with the Camp's range area where the building is located. Maps showing the specific locations of each of these buildings within Camp Ripley will be provided to the Contractor after award of the contract. Table 1.

Eligibility under Criteria B (associations with significant persons) and C (possessing a distinctive type, period, or method of construction) and the various aspects of Integrity (location, design, setting, materials, workmanship, feeling and association) should also be considered. Criterion D (historic information potential) and criteria considerations a through f may not be applicable. Two applicable National Register Bulletins include No. 15: How to Apply the National Register Criteria for Evaluation and No. 22: How to Evaluate and Nominate Potential National Register Properties That Have Achieved Significance Within the Last Fifty Years. 2.05 Two previous studies have been conducted of the Minnesota Army National Guard's Cold War Era buildings at Camp Ripley in Morrison County and at Arden Hills Army Training Site (part of the former Twin Cities Army Ammunition Plant) in Ramsey County (ref. Blythe, 2009, Minnesota Army National Guard Cold War Thematic Study (1946-1989) and Inventory of Early Cold War Era Properties (1946-1961), Minnesota Army National Guard, Minnesota and Blythe, 2004, A Cold War Thematic Study and Properties Inventory of Twin Cities Army Ammunition Plant, Ramsey County, Minnesota). The Cold War Era historic contexts prepared as part of these studies should be at least partially applicable to the Cold War Era buildings to be evaluated under the present contract. Copies of these two reports are on file at the State Historic Preservation Office, Minnesota Historical Society, 345 Kellogg Boulevard West, St. Paul, Minnesota (reference also SHPO file numbers 2008-1580 and 2004-1056). 2.06 Recent evaluation of the National Register eligibility of the late period Cold War Era buildings at the MNARNG's armories throughout Minnesota was completed in 2011-2012 (ref. Trnka, 2012, Minnesota Army National Guard Inventory of Late Cold War Era Properties (1961-1989): Multiple Counties, Minnesota, J. Trnka Consulting, LLC, Bloomington, Minnesota). A copy of this report will be available to the Contractor at the Camp Ripley Environmental Office after late August 2012. 3.00 DEFINITIONS 3.01 Cultural Resources include any building, site, district, structure, object, data, or other material relating to the history, architecture, archeology, or culture of an area. 3.02 A Phase I Cultural Resources Investigation is an intensive, on-the-ground study of an area sufficient to determine the number and extent of the resources present and their relationships to project features. It will provide (1) data adequate to assess the general nature of the sites present; (2) recommendations for additional testing and/or archival research of those resources that may provide important cultural and scientific information. 3.03 Phase II Evaluation is the intensive testing of and/or field and archival research on a resource that may provide important cultural or scientific information. This testing and research will result in (1) information adequate to determine whether the resource is eligible for inclusion on the National Register; (2) a Phase III mitigation plan for any eligible resources that will undergo a direct or indirect impact. 3.04 Phase III Mitigation is the mitigation of direct or indirect impacts of construction or major maintenance upon National Register eligible or listed sites through the systematic recordation or removal of data. For archeological sites, it typically includes the excavation of either complete cultural deposits or a systematic sample of them and the thorough analysis and interpretation of the data recovered. In addition, because the mitigation process destroys the resource, data should be recovered that may be needed to address future research questions. For architectural properties, mitigation may include photographic and scaled drawing documentation and preparation of a detailed history of the property. Mitigation measures must be adequate to address the important research questions based on which the resource was determined eligible. 4.00 SURVEY AND EVALUATION REQUIREMENTS 4.01 The Contractor will conduct Phase II Evaluation of the late period Cold War Era buildings at Camp Ripley listed in Table 1 in accordance with sections 2.01-2.06 and 3.03 above. 4.02 The Contractor's work will be subject to the supervision, review, and acceptance of the Corps' Technical Representative. The Corps' Technical Representative for this contract is Ms. Virginia Gnabasik, St. Paul District archeologist, at +1 (555) 000-0000. 4.03 The Contractor will not proceed with work that is or appears to be beyond this scope of work. If additional work is required and within scope, a bilateral modification to the contract will be issued prior to the start of additional work. No action should be taken outside the scope of work as defined in the contract in the absence of a signed modification. 4.04 Ms. Virginia Gnabasik should be contacted at least five business days prior to the start of field work. 4.05 The Contractor will employ a systematic, interdisciplinary approach in conducting the study, using techniques and methods that represent the current state of knowledge for the appropriate disciplines. The Contractor will provide specialized knowledge and skills as needed, including expertise in history, architecture, architectural history, and other social and natural sciences. 4.06 The Contractor's key personnel working on this project must meet the Secretary of the Interior's Standards and Guidelines for Archeology and Historic Preservation (as amended and annotated), which is available at 4.07 The Cold War Era buildings at Camp Ripley listed in Table 1, which are to be evaluated, are all on land owned by the State of Minnesota, Department of Military Affairs, in Morrison County, Minnesota. 4.08 The Contractor will provide all materials and equipment necessary to perform the required services expeditiously. 4.09 The Contractor's field investigation and archival research will be sufficient to determine whether the resources present meet the National Register of Historic Places eligibility criteria and criteria considerations listed in 36 CFR Part 60 and to complete documentation required in 36 CFR Part 63. 4.10 If any of the buildings appear to be eligible, modification of the contract may be undertaken at the Government's option to cover the cost of the Contractor preparing a Determination of Eligibility for the National Register of Historic Places. 4.11 A standing structure form should be prepared for each of the 86 Cold War Era buildings to be evaluated. Data should be included on the present condition of the building, on the types and locations of information (drawings, photographs, etc.) available on the building, on the contents and locations of any collections from it, and on the building's relation to other buildings or structures at that particular range training area or cantonment area. The Contractor will submit the standing structure forms to Mr. Thomas Cinadr, Inventory and Information Management Coordinator, State Historic Preservation Office, Minnesota Historical Society, 345 Kellogg Boulevard West, St. Paul, Minnesota 55102-1906, [phone: +1 (555) 000-0000] for official building numbers. 4.12 The Contractor will use a global positioning system (GPS) to record the location of each building being evaluated. The Corps' preferred GPS data format is UTM (Projection), NAD 83 (Horizontal Datum), and Meters (Units). 4.13 The Contractor will recommend any Phase III mitigation measures that are warranted. 4.14 The Contractor's field personnel are required to take a one-half hour safety briefing prior to being allowed to work in the Camp's range area. 4.15 The speed limit on the range area roads is 25 mph, meaning that up to 60 minutes may be required to drive from the range office to buildings located in the north end of the range area. A four-wheel-drive vehicle should not be necessary. 4.16 June, July and August are the busiest training months at Camp Ripley, but range use occurs throughout the year to varying degrees. All field work in the range area will have to be scheduled around the Camp's training/range use activities. Daily range bulletins depicting areas in use are available from the Camp's range office. 4.17 In addition, the Contractor may wish to work around the deer hunting events at Camp Ripley, as there will be up to 2,500 extra vehicles in the cantonment area and range area on those dates. Youth archery hunt dates are October 5-7, 2012 and the general archery hunt dates are October 18-19 and October 27-28. 5.00 GENERAL REPORT REQUIREMENTS 5.01 The Contractor will submit the following documents, described in this section and Section 6.00: a field report, field notes, a draft contract report, and a final contract report. 5.02 The Contractor's field report will be a brief summary of the nature, extent and results of the field work conducted. It may be in the form of a letter to the Corps' Technical Representative. 5.03 The Contractor's field notes will include legible copies of important notes and records kept during the investigation. Especially important are the daily field journals of the Principal Investigator, historian and/or architectural historian(s). One copy of these notes should be submitted to the Corps' Technical Representative with the draft contract report but should not be bound into the report. 5.04 The draft contract report will detail the approach, methods, and results of the investigation and make recommendations for further work. It will be submitted to the Corps' Technical Representative, who will review it and forward it to the Camp Ripley Environmental Office and other appropriate agencies for review. Comments will be returned to the Contractor, who will make the necessary revisions and submit the final contract report. 5.05 The Contractor's draft and final reports will include at least the following sections, as appropriate to the study. The length of each section depends on the level of detail required of the study and the amount of information available. The reports should be as concise as possible, yet provide all the information needed for evaluating and managing the project and for future reference. a. Title page: The title page will provide the following information: the type of study; the types of cultural resources assessed (archeological, historical, architectural); the project name and location (counties and state); the date of the report; the Contractor's name; the contract number; the name of the author(s) and/or Principal Investigator; the signature of the Principal Investigator; and the agency for which the report is being prepared (St. Paul District, U.S. Army Corps of Engineers and Minnesota Army National Guard, Camp Ripley Environmental Office). b. Management summary: This section will provide a concise summary of the study, containing all the information needed for management of the buildings. This information will include the reason the work was undertaken, who the sponsor was, a brief summary of the scope of work and budget, a summary of the field work and archival research, the limitations of the study, the results, the significance of the results, recommendations for further work, and the repository for records and artifacts. c. Table of contents d. List of figures (includes plates) e. List of tables f. Introduction: This section will identify the sponsors (Corps of Engineers and Camp Ripley Environmental Office) and their reason for the study and present an overview of the study with each Cold War Era building located on USGS quadrangle maps. It will also define the location and boundaries of the study area (using Camp Ripley specific maps); define the study area within its regional cultural and environmental context; reference the scope of work; identify the institution that did the work and the number of people and person-days/hours involved; give the dates when the various phases of the work were completed; identify the repository of records and artifacts; and provide a brief outline of the report and an overview of its major goals. g. Environmental background: This section will briefly describe the current environment of the study area, including its geology, vegetation, fauna, climate, topography, physiography, and soils. The relationship of the environmental setting to the area's history should be stressed. The level of detail in this section will be commensurate with that of the other report sections. h. Previous studies: This section will briefly summarize and evaluate previous archeological, historical and architectural research in the study area including the researchers, dates, extent, adequacy, and results of past work and any cultural/behavioral inferences derived from it. i. Historic context: This section will present historic context information on the Minnesota Army National Guard, Camp Ripley, and the Cold War Era from 1961-1989, which information will be useful in evaluating the National Register of Historic Places eligibility of each of the buildings under criteria A, B and C, as well as criteria consideration g. j. Theoretical and methodological overview: This section will state the goals of the sponsor and the researcher, the theoretical and methodological orientation of the study, and the research strategies that were applied to achieve the goals. k.
