Statement of Work

SECTION 110 INVENTORY AND SITE REVISITS WITHIN AND AROUND THE

LEONARDS BASIN HERITAGE AREA IN DOMINGUEZ-ESCALANTE NATIONAL

CONSERVATION AREA

1. INTRODUCTION

1.A. Background

1.A.1. The Bureau of Land Management (BLM) is required, under Section 110 of the National Historic Preservation Act of 1966 (as amended) (NHPA), to maintain an historic preservation program that, among other responsibilities, identifies and evaluates historic properties under agency jurisdiction. Identification can be carried out in a number of ways. BLM cultural resource specialists use identification and recordation of historic properties in combination with information gained through consultation with affected Tribes, the Colorado State Historic Preservation Officer (SHPO), and other consulting parties to determine plans for management and protection of any site.

1.A.2. Class III (intensive) cultural resource inventory is guided by the consultation process outlined in the State Protocol Agreement (Protocol) with the Colorado SHPO dated October 29, 2014. Inventory standards and guidelines are specified in the most current BLM Colorado Handbook of Guidelines and Procedures for Inventory, Evaluation, and Mitigation of Cultural Resources and associated Digital Data Specifications Guide, Colorado SHPO standards, District and field office standards and procedures and other supplemental guidance.

1.A.3. A cultural resource overview of the project area is being provided below with the intent of assisting prospective offerors with more specific inventory information about areas adjacent to the project areas. It is frequently the case that a similar site density with similar site types can be expected in the project area if it is a similar landscape, however, this is not always true. Prospective bidders should not assume that this overview is anything more than an informed projection of what could possibly be present in the project area.

1.B. Objectives

1.B.1. Place of Performance:

The project is located in the Leonards Basin Heritage Area (LBHA) in the DENCA, approximately 14 miles west of Delta, Colorado. Access is via U.S. Highway 50 to Escalante Canyon Road. Once at the Gunnison River access is on BLM routes along the river approximately 3.5 miles from the intersection of Escalante Canyon Road and the Gunnison River. Please enquire with the PI/COR contact below for additional access information.

1.B.2 Project Undertaking:

The project entails cultural resource inventory and site re-recordings within and near the LBHA.

The LBHA is a 450-acre parcel within the DENCA that was created to protect the integrity of setting and place with a focus on prehistoric rock art, geological, and biological heritage within the area. Heritage areas are characterized by distinctive natural, cultural, historic, and scenic resources that, when linked together, tell a unique story. In this manner, the LBHA will help maintain and protect the cultural integrity of setting and preserve the natural landscape characteristics of the area. Also included in the inventory are nearby drainages – Gunnison and Palmer Gulches – which exhibit similar characteristics to the LBHA, including several known rock art sites, and may be considered for inclusion in an LBHA expansion.

Heritage areas are defined in the D-E NCA Resource Management Plan as places where natural, cultural, and historic resources combine to form a cohesive, important landscape. The three Ute tribes (the Ute Indian Tribe of the Uintah and Ouray Reservation [UIT], the Southern Ute Indian Tribe [SUIT], and the Ute Mountain Ute Tribe [UMUT]) have indicated for years in consultation that the agency needs to incorporate this type of landscape approach to cultural resource management. The D-E NCA RMP directs the agency to use this area to consult with Native American tribes to set management objectives for the LBHA. The LBHA is known to contain both archaeological sites of interest to the tribes, primarily rock art.

1.B.3. Proposed Class III Inventory:

A Class III inventory is being contracted to identify cultural resources within and near the LBHA, totaling approximately 635 acres. Cultural resource sites that could be encountered include prehistoric open or sheltered camps or lithic sites, rock art sites, historic camps, and historic grazing-related sites, among others. As per OAHP guidelines, it is not necessary to fully document features such as dirt roads, stock ponds, soil berms, fence lines, small irrigation ditches, pastures, or fields unless they are part of a larger site.

1.B.4. Proposed Site Revisits and Rerecording:

In addition to the inventory, 17 existing sites require full re-recordings on appropriate OAHP forms.

Site Number Site Type 5DT.53 Prehistoric rock art 5DT.54 Prehistoric open lithic and rock art 5DT.55 Prehistoric open lithic 5DT.60 Prehistoric open lithic 5DT.61 Prehistoric open lithic 5DT.62 Prehistoric open lithic 5DT.63 Prehistoric sheltered lithic 5DT.64 Prehistoric and historic rock art 5DT.65 Prehistoric sheltered lithic 5DT.66 Prehistoric sheltered camp 5DT.67 Prehistoric open lithic 5DT.68 Prehistoric sheltered lithic and rock art 5DT.1690 Prehistoric Rock Art 5DT.1691 Prehistoric Rock Art 5DT.1692 Prehistoric Rock Art 5DT.1693 Prehistoric Rock Art 5DT.1694 Prehistoric Rock Art

1.B.5. Proposed Visual Landscape Assessment

Produce a narrative (one to two paragraphs) separate from the inventory report regarding conditions at three locations within the inventory area, regardless of results. There is no standard checklist for each location but features such as vegetation, landforms, water, color, and adjacent scenery, should be included. Other factors, if applicable, can include, identified visitor use, amount of use, and adjacent land uses.

Include photograph observation points (with UTMs) in each cardinal direction at each location.

Also include additional photos that highlight unique elements or viewsheds that add to or detract from the landscape.

Further information on survey requirements and methodology are below.

Compliance with NHPA and Resource Management Plans:

This project ensures compliance with Section 110 of the National Historic Preservation Act (NHPA) and with the BLM DENCA Resource Management Plan that requires the identification, evaluation, and preservation of cultural resources. No specific undertaking is currently associated with this project that could impact cultural resources; this project is being conducted for identification and protection of cultural resources.

2 CONTRACT REQUIREMENTS

The contractor must hold a current Colorado BLM Cultural Resource Use Permit (CRUP).

The field crew chief must be on the current CRUP of the selected contractor(s), must be qualified to do cultural work in the Grand Junction Field Office, and must be present at all times with crews in the field. This is a three-item contract with deliverables due on the schedule in the reporting section below and will ultimately result in the reporting on the results of a Class III inventory and monitoring. The three work items are: 1) a letter report, 2) a draft report, and 3) a final report. The fieldwork will be completed to assure that the contractor meets the deadlines for submission of the final report described below. A final report on the results of the fieldwork will be delivered by July 1, 2025 (see report schedule). All reports and supporting documents will meet professional guidelines established by the Colorado Office of Archaeology and Historic Preservation (OAHP) and the Department of the Interior/BLM. The boundaries of the cultural inventory corridor are not flagged. Use of a Global Positioning System (GPS) unit to locate and plot both the inventory area as conducted by the contractor and to plot and provide UTMs for cultural resources is required.

Contractors must also follow the current BLM Handbook, BLM Colorado Southwest District and Upper Colorado River District Procedures and Reporting Standards, the most recent BLM Colorado Digital Standards, and the CRUP permit procedures including delivery of all site and survey parcel information in shapefiles with supporting tables to support both survey information and site/isolate information.

Note: The project bid should include evidence of satisfactory staff member experience inventorying, recording, and evaluating prehistoric and historic cultural resources; and evidence of technical capability of staff (i.e. use of tools such as GPS, etc.).

3 TASKS

3.A Literature Review and Field Inventory

The purpose of the file search documentation is to develop a context to discuss the results of the contractor’s survey in the report. The contractor will be responsible to check the GLO maps, quadrangle maps, aerial photos, grazing records, and Land Patents for historic site potential, and Office of Archaeology and Historic Preservation files and/or Compass database to identify previous surveys and recorded sites within a one-mile radius of the boundary of the project area.

GLO information, grazing records, and survey notes are available at the UFO and DENCA (GJFO), the BLM State Office, and at http://www.glorecords.blm.gov/. Aerial photos can be obtained online at the Mesa County GIS webpage. Information from aerials, grazing records, and GLO records, including maps, must be included in site records and the final report where historic features are extant (i.e. roads, trails, or structures) or where historic artifact scatters are spatially associated with historically mapped features. The GLO records and land patent (homestead) records must be checked by the contractor and all significant or named (as per OAHP guidelines) roads, trails, etc. over 50 years old will be mapped (if extant) and recorded as part of the cultural survey. Significant or named historic roads or trails that likely have been obliterated by the modern transportation system (based on alignment on GLO maps) must be recorded. This requirement will be discussed in detail during the pre-work file search.

A remote Field Office literature review (file search) must be conducted with both the UFO and DENCA (GJFO) field offices prior to starting fieldwork. The Contractor must contact the project inspector (PI) at least two weeks in advance to request the BLM file search (please send the field work authorization at this time). Site forms for known sites within the project area can also be obtained during the literature review.

For this inventory, Class III inventory will be conducted to identify and record all cultural resources encountered during survey. All fieldwork and documentation shall be performed to DOI, BLM, Colorado OAHP, UFO, DENCA, and other applicable professional standards. If vegetation density becomes an issue, the contractor must discuss alternative courses of action with the project inspector prior to changes in survey technique.

If the field crew has any concerns or questions regarding the interpretation of the BLM procedures and standards, it is the contractor’s responsibility to coordinate with the BLM PI in determining how to manage the recording of isolated finds, the need for testing features, and determining site boundaries.

No permanent datum will be installed at any site, however, a GPS (virtual) datum with UTM coordinates is required and must be included in each site plan map. Each site recording must include, at a minimum, two photographs: one general view of the site with a person in view standing at the datum and one general view or overview of the surrounding environment including the horizon if possible, or a view from the site. Any site with a feature(s) must have a photograph of each feature(s) with a scale in the photo. Site sketch maps must plot formal tools, features, and areas identified as artifact concentrations. At sites that are lithic scatters with only debitage, crews must plot artifact concentrations and artifacts identified and use these to determine the boundary of the site. All site records will include an estimation of potential soil depth based on probing, auger, shovel tests, or exposures of the soil profile in natural features such as drainages or arroyos.

The site maps and descriptions will also include any natural disturbances or modern intrusions to the site, including but not limited to, intrusions such as trash dumping, artifact collector piles, historic vegetation treatments such as chaining, unauthorized excavation, off road vehicle activity, cattle or wildlife trampling or trailing, and natural disturbances such as fire or erosion. Discuss intrusions or impacts that have altered the eligibility of a site or have the potential to affect the integrity of a Need Data or Eligible site on the site forms and in the report narrative.

To refine National Register eligibility recommendations, evaluative testing (shovel or trowel) will be made on all sites that have a final field assignment of Need Data under Criterion D (potentially eligible for nomination to the NRHP). This testing will be completed during the field inventory and should be used to determine the potential for subsurface cultural deposits and the site boundary if there are any questions that lead the field crew to recommend Need Data. This level of testing should not require the retrieval of artifacts for further analysis or curation. If subsurface artifacts that do not meet the criteria for collection are discovered during testing, they will be replaced into the test unit and reburied with the backfill. Any tests will be mapped with GPS and included in the site plan map. Any artifacts collected during the survey will require a discussion in the final report as to the purpose of collecting the artifact specific to the criteria for collection and the information that may be retrieved by future research (BLM Colorado Handbook 1998, revised 2017). All collected material is to be curated according to standards provided in 36 CFR 79 and deposited at the Museum of Western Colorado in Grand Junction.

3.B Reporting

3.B.1 Item 1 payment (30% of total contract) will be made based on acceptance of a preliminary letter report within two weeks of completing the fieldwork, or no later than April 15, 2025, whichever comes first. The letter report should contain, at a minimum:

• A brief description of each site, which will include site type, temporal or cultural affiliation, and the NRHP eligibility recommendation. This information can be in table format.

• A 7.5' topographic map showing the project survey boundary and site locations.

3.B.2 Item 2 payment (50% of total contract) will be made based on acceptance of a secure electronic transfer (no email) or FTP site transfer to the PI containing the GPS shapefiles of the sites, isolated finds, and surveyed areas, and digital copies of the draft final report, site and/or isolate forms, and visual landscape assessment submitted to the BLM for review within eight weeks of completing the fieldwork, or no later than June 15, 2025, whichever comes first. The consultant’s editor is strongly encouraged to review the draft before submission to correct grammatical and factual errors.

The draft report and all required survey and site forms and shapefiles will meet the guidelines established by the Secretary of Interior’s Standards (and Guidelines for Archaeology and Historic Preservation), the BLM Colorado Handbook, Colorado BLM-OAHP Digital Data Specifications Guide, the Colorado Office of Archaeology and Historic Preservation Guidelines and the current BLM Northwest District and Upper Colorado River District Procedures and Reporting Standards for Cultural Resource Consultants Conducting Projects under a CRUP Permit. The contractor is encouraged to review the OAHP survey report checklist to be sure their submissions meet the OAHP requirements. A complete list of the previous surveys and complete site and isolated find numbers found during the literature search are expected to be included in an appendix to the report, in addition to a summary discussion in the text.

The draft final report will evaluate the sites and recommend National Register eligibility, as well as address site condition and potential threats to resources. Those evaluations should be made in the context of previous investigations and findings in the general area, and management issues for the region. All sites brought forward in the final report as Need Data will include a detailed discussion of how field testing was conducted, why field testing was inconclusive, and will include specific recommendations for evaluative testing to determine eligibility. Discussion of disturbances or intrusions observed while conducting the fieldwork that are currently or have the potential to impact Need Data or Eligible sites should be included in recommendations for site management. Noted potential threats to the resource should be verified with evidence and/or reasonable expectations of disturbance (e.g. natural erosional processes should not be noted as an impact or threat; grazing should not be noted as an impact or threat unless clear evidence of disturbance has already occurred or unless grazing activity is expected to change or increase).

The BLM will provide a response to the draft Final Report within one month of receipt.

3.B.2 Payment of Item 3 (20% of contract) will be made based on acceptance of the Final Report and supporting records no later than July 1, 2025, or two weeks after BLM has returned comments on the draft Final Report, whichever comes first. The BLM will notify the contractor of acceptance of the Final Report within two weeks, which constitutes completion of the contract.

The final submission will include secure electronic submission of the project shapefiles and PDFs of the report and site forms (use of a secure FTP site is preferred, though encrypted flash drives will also be accepted). If minimal changes are required, specific corrections will be identified in the response and individual corrected pages may be submitted.

3.C General Requirements

3.C.1 Site Confidentiality: To protect site information from unauthorized disclosure, all site location and content information must be kept in strictest confidence. The Contractor shall make the information available only to the COR/PI and must take whatever internal measures are necessary to ensure that confidential material is protected. All site-specific records, photographs, and maps generated in the course of this contract, including original field maps and notes, will be considered BLM property and will be turned over to the COR/PI upon completion of the project.

The Contractor will be responsible for ensuring that all excess site-specific documents, maps, site forms, etc., (i.e., those not submitted as deliverables, internal review drafts, etc.) are properly disposed of upon completion of the project.

3.C.2 Ownership: The BLM retains ownership of, and all rights to, all artifacts collected, records, data, maps, drawings, photographs, samples, artifacts, GIS products, automated data bases, or other products. These items cannot be used by the Contractor without written permission from the

BLM.

3.C.3 Collection and Curation: Qualified individuals may be authorized to remove cultural resource materials which are in danger of loss or which are needed for scientific study, public interpretation, or evaluation of the cultural property. Additionally, no paleontological resources may be collected under a cultural resource permit, unless the remains are in an archaeological context (ex. paleo bone in hearth, etc.), however, the BLM paleontologist or paleontology coordinator should be consulted. Cultural resource materials removed from BLM-administered land in Colorado, along with copies of the associated records, are curated as property of the United Sates in a repository designated in the CRUP.

3.C.3.a Collection: Only limited collections in certain circumstances will be made on BLM-administered lands in Colorado in the following circumstances.

3.C.3.b Collection Procedures: The BLM generally adheres to a no collection policy. Collection is only required, if in the opinion of the Field Office archaeologist, the artifact(s) are unique and vulnerable to unauthorized collection or destruction, diagnostic (time-sensitive), and cannot be readily identified in the field. If collection is approved, the following stipulations apply:

• A catalog sheet, drawings and/or photographs of the artifact(s), and location of the collection will be included in the body of the report and attached to the appropriate site form(s).

• The location of collected artifacts shall be accurately plotted on site sketch maps. (Please see the most current Procedures and Reporting Standards for Cultural Resource Consultants Conducting Projects Under a CRUP Permit for the Colorado Northwest District and Grand Junction Field Office, Bureau of Land Management for more information and collection specifics).

3.C.3c Curation: Collected artifacts must be curated according to the standards of the facility designated as the curatorial repository in the CRUP.

4 DEFINITIONS

4.A Cultural Resource or Cultural Property: Any definite location of past human activity, occupation, or use, identifiable through field inventory (survey), historical documentation, or oral evidence. This term may be applied to archaeological, historic, or architectural sites, structures or places, or places of traditional cultural or religious importance to specified social and/or cultural groups, whether or not represented by physical remains.

The types of cultural resource or cultural property are presented below. Modifications to these definitions may be identified in District-wide and individual Field Office procedures and agreed upon by the BLM on a case-by-case basis:

4.A.1 Site: A physical location of previous (50-year age minimum) human activity at which the evidence suggests repeated and patterned use over time, or multiple classes of activities. Certain cultural resources that represent single activity use may be considered eligible for the NRHP and will be defined as sites. For example: a) Isolated thermal features such as hearths due to the potential for chronometric and economic information; b) Single element rock art panels due to the potential diagnostic and cultural value of the motif; c) Isolated human burials; or d) Loci exhibiting ground stone and flaked stone in association due to the potential of being open camps.

4.A.2 Isolated Find (IF): A location of previous (50-year age minimum) human activity at which are found one or more culturally modified and transportable objects representing a single activity and not found in the context of a site as defined above. Note that this definition makes no reference to an absolute quantitative standard for the site/isolate distinction. For

4.A.3 Districts/Structures/Objects/Buildings: These resources are defined within the NHPA and its implementing regulations. The Contractor will need to contact the COR/PI to determine if special recordation of any such properties is required prior to completion of fieldwork.

4.A.4 Cultural Landscape: These resources are usually represented by a widespread artifact scatter and/or series of structural features scattered over a large area (i.e. quarry sites). These areas often cover tens to hundreds of square acres. Accordingly, the contextual relationship between the scatter of artifacts is difficult to define. There are several of these resources defined within Colorado. The Contractor will need to contact the COR/PI to determine what documentation will be necessary to record a previously unrecorded cultural landscape.

4.A.5 Aboriginal Cultural Resource Forms: All wickiups, platforms, brush fences, or other similar aboriginal wooden or brush structures will require an Aboriginal Wooden Structure Component Form for each structure in addition to the OAHP Prehistoric Component Form. All cultural modified trees will require a Culturally Modified Tree Form, and historic well pads should be recorded with the BLM Historic Well Pad Component Form in addition to the Prehistoric or Historic Component Form.

4.A.6 Linear Resources: All linear sites encountered will include the recording of the full linear site and the segments within the project area using the BLM Linear Management Data Forms and the BLM Linear Segment Forms. All of these forms can be requested from the BLM.

4.B Inventory: A process of descriptive listing and documentation of cultural resources within a defined geographic area. Included are syntheses of previously recorded cultural resource data, systematic examinations of the land surface for physical indications of past human activity, and the use of interviews or other related methods to locate previously unrecorded cultural resources not identifiable through physical examination.

4.B.1 Class III Inventory

4.B.1.a Class III inventories are professionally conducted, continuous, intensive pedestrian surveys of an entire target area (100%).

4.B.1.b Class III inventories are aimed at locating and recording all cultural resource properties that have surface and exposed-profile indications, through systematic inspection carried out by a crew of trained observers walking a series of parallel transects until the area has been thoroughly examined. Crew spacing should not be wider than 15-20 meters apart. Intensive inventory describes the distribution of properties in an area; determines the number, location and condition of properties; determines the types of properties actually present within the area; permits classification of individual properties; and records the physical extent of specific properties.

4.B.1.c Class III inventories may require the artificial (i.e., probing, troweling, shovel tests, etc.)

exposure of the subsurface, but only to point of determination of site eligibility.

4.C Evaluation: The evaluation of cultural resources requires a determination of site eligibility for the NRHP using National Register eligibility criteria (36 CFR 60).

4.D Historic Property: Any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion in the NRHP. The term includes, but is not limited to, artifacts, records, and remains that are related to and located within such properties. The phrase ‘eligible for inclusion in the NRHP includes both properties formally determined as such by the Secretary of the Interior and all other properties that meet National Register listing criteria and those sites already identified as eligible during consultation between the BLM and the Colorado SHPO.

4.E Undertakings: Actions assisted, licensed, permitted, approved, funded, or authorized by BLM, as defined in the Code of Federal Regulations [36 CFR 800.2(o)]. Undertakings for which BLM is considered the lead agent, whether or not they involve federal lands, are federal actions.

5 COORDINATION

5.A The Contractor must be highly flexible and able to adapt to rapidly changing circumstances.

Close coordination with the CO and COR/PI will be necessary to meet BLM deadlines. If problems arise, they first shall be discussed with the COR/PI. The Contractor must be able to quickly "gear-up" to execute assigned tasks within short time frames.

5.B The Contractor shall be responsible for obtaining and coordinating access across private lands for the purpose of conducting work under this contract, contact information will be provided. The Contractor shall advise the COR/PI within one (1) working day of any access restriction which would significantly delay progress.

5.C The Contractor shall be prepared, at the request of the BLM, to incorporate into their work plans a method by which the public can be informed and educated about activities under this contract. Any contacts with the news media or other public concerning work performed under this contract shall first be cleared through the COR/PI.

5.D Any problems which may delay the Contractor’s work schedule must be reported immediately to the COR/PI.

5.E The Contractor’s project director and all field supervisors must have a valid BLM Colorado Cultural Resource Use Permit (CRUP) and have submitted a Fieldwork Authorization request prior to the initiation of fieldwork. A Fieldwork Authorization Request must be submitted to the Grand Junction Field Office, 2815 H Road, Grand Junction CO 81506 or via email to the COR or PI and should be submitted prior to the file search conducted in the Grand Junction Field Office.

5. F During the course of the project, reasonable precautions will be taken to avoid the disclosure of site locations to all but authorized personnel. In addition, field personnel will be required to keep all motorized vehicles on existing roads and trails. Field personnel will contact the COR at least one week prior to initiating fieldwork.

6 PROGRAM MANAGEMENT AND CONTROL REQUIREMENTS

6.A Work performed under this contract shall be monitored according to contract specifications, provisions, and the Contractor's proposal. The Technical Proposal to this RFP shall thoroughly discuss cost and schedule control as well as quality control.

6.B Cost and Schedule Control: Adherence to costs and schedules contained in the award shall be closely monitored. The Contractor’s response shall specify individuals who shall be responsible for monitoring costs and schedules. Each type of task included in Section 3 above, shall be structured as a series of steps, each with identifiable goals and end points. Progress shall be evaluated periodically and shall be included in the progress/letter report, if required.

Communication between administrative and technical staffs shall be maintained according to the specified procedures. A detailed plan for the early identification and resolution of problems (i.e., scheduling delays due to inclement weather, etc.) shall be prepared and followed. Potential problem areas shall be identified in consultation with the technical and administrative staffs before work begins. All records of actual time and costs charged to this contract shall be made available for inspection upon request by the BLM.

6.C. Quality Control: Control over the technical quality of all work and deliverables shall be closely monitored by the Contractor to assure required BLM and other professional standards are met. Within the Technical Proposal to this RFP, explicit procedures shall be provided that assure periodic quality checks on field/laboratory methods and products (site records, artifact attribute sheets, final reports, etc.) associated with individual orders. A discussion of actual procedures which shall be followed to monitor progress and assure quality control shall also be included within the Technical Proposal. These procedures could include periodic meetings with staff, field or laboratory inspections, independent checks of analytic procedures, etc.
