I. Introduction

The National Park Service (NPS) proposes a series of archeological actions prior to projects that will rehabilitate the exterior, improve drainage, waterproof the basement, and make structural repairs, at several historic houses in Yorktown, Virginia. The proposed work will include Phase I and II Testing to identify intact soil layers and make determinations of eligibility. The project areas include the areas immediately surrounding four historic homes in Yorktown including the Dudley Digges House, the Ballard House, the Smith House, and the Nelson House. An area three feet in width surrounding the foundation will need to be excavated during the treatment of water infiltration issues.

At the Dudley Digges House the project includes sealing the exterior to staunch water infiltration, developing a French drain system, the removal and relocation of a wooden, exterior access ramp and rehabilitation of the existing geothermal system. The Dudley Digges house served as the Colonial NHP Superintendent’s house until 2014 and has remained close since. The current geothermal system has not performed according to standards and does not adequately control the temperature within the building. Hydrologic pressure continues to build and has caused some damage to the cellar foundation and occasionally water enters the basement through the walls of the structure during heavy rains. The modification of the existing geothermal system including the transition from a horizontal to vertical system placed deeper in the ground will allow the system to function appropriately and will maintain temperature developing an exterior rehabilitation is critical to prevent further deterioration and failure of other building components, loss of historic fabric, and possible damage to the museum collections. A two foot wide by four foot deep continuous trench against the foundation of the mansion is proposed for installation of a sub-surface drainage system. The drainage system will connect to two drywells that are proposed on the western side of the mansion. In addition, several four-foot wide by four-foot deep foundation probes are proposed to assess the sub-surface status of the wall, portico pier, and stairway foundations. (See Figure 1, Proposed Excavation Plan)

The Ballard House work will include efforts to prevent water infiltration into the foundation and basement. The project will include sealing the exterior to staunch water infiltration. A two-foot-wide by four-foot-deep continuous trench against the foundation of the house is proposed for installation of a sub-surface drainage system.

The Smith House has an external brick drain system that is cracked and failing in places. The project calls for investigating the existing conditions and taking efforts to prevent water infiltration including the installation of drain board and developing a French drain system.

The Nelson House project will treat water infiltration issues that are impacting the basement foundation. The project calls for investigating the existing conditions and taking efforts to prevent water infiltration including the installation of drain board and developing a French drain system.

The following scope of work details requirements to be performed in support of NHPA Section 106 compliance for the proposed rehabilitation of several structures. Previous archaeological testing has been conducted within portions of the proposed area of potential effect (APE), Much of the previous archeological testing at the Dudley Digges House was conducted in the 1950s and 1960s. In addition, previously undocumented utility installation has occurred in the area of the structures. The early archeological work was conducted as the field of historical archeology was in its infancy and before modern archeological methods and practices were developed. Recent archeological work at other sites in Yorktown that were previously excavated during that early period have provided valuable additional information. Based on documentation it appears that portions of the foundation wall were previously excavated, but other sections may have potentially significant archaeological deposits at varying depths below the current grade. It is unknown whether significant deposits will be encountered within the proposed project APE. At the Ballard House a large portion of the side yard was investigated, but areas directly adjacent to the house have not been tested. Testing at the Smith House also focused on the rear and side yards and left the area adjacent to the foundation untested or documented. Portions of the Nelson House foundation were excavated in the 1970s during the same project as the Ballard and Smith houses. Portions of the north, south, and west foundations were excavated during the field work.

The purpose of the archeological testing will be to ensure that ground disturbance required for impending construction does not result in loss of valuable archeological data. Approximately 50 shovel tests, 10 1x2 meter excavation units and 10 1x1 meter units are anticipated to reveal stratigraphy and artifactual evidence associated with potentially uncovered resources, and permit determinations of eligibility, and recommendations for additional testing, monitoring, and possibly mitigation.

Background

Dudley Digges House

The Dudley Digges House was built c. 1760 by Dudley Digges on Lot 77 although his landholding also included adjacent lots 76, 78, and 79. The house is Colonial architecture. It is one and one-half stories, fifteen rooms, cellar and attic, pegged, brace frame covered with weatherboards, on brick Flemish bond foundation, gable roof with cedar shingles, modillioned exterior cornice, and five dormers on front. The building measures 4,200 square feet. The house was restored by the NPS between 1954 and 1960. During this restoration a 19th or 20th century addition was removed from the northeast corner of the Digges House.

The Yorktown Archeological/Historical Assessment (Grzymala 1998) identified several archeological projects that have taken place within or adjacent to the proposed APE for the repair, rehabilitation, and protection of the Dudley Digges House project. In 1956, John Cotter conducted exploratory investigations across lots 76, 77, 78, and 79, prior to the restoration of the property. A grid system was established across the four lots and probing using a three-foot-long probe was conducted at one-foot intervals and two-foot wide trenches were dug at 10-foot intervals. The goals of this testing were to identify any buried historic period structures on the lots. A brick pad was found under a portion of the 19th century kitchen addition on the main house. In 1958 work was conducted by John Griffin to reinvestigate several of the dependencies including the external kitchen and the granary. This work also focused on identifying and studying structural foundations. No work was done near the main house. In 1959, during the restoration of the house the sandy cellar floor was screened and examined. It was determined that the original floor was likely covered with wooden planks. In 1960 work was conducted in front of the existing Digges House that identified the basement foundations of an earlier structure. Structure L was fully uncovered located between the existing Digges House and Main Street. Drawings and photographs associated with this project indicate that the majority of the south/front yard were impacted during those excavations. In 1990 archeological testing was conducted prior to the placement of geothermal system in the rear of the Dudley Digges House. Testing for this project included 8 less than one-foot diameter holes, a trench running from the rear of the house to the geothermal system, and several pits that were three feet in diameter. In 1997 Colonial Williamsburg Foundation archeologist Elizabeth Grzymala monitored the installation of a gas line. This work included the excavation of a 16” wide and 24” long hole was dug to a depth of 2 feet at the southwest corner of the yard outside of the picket fence. The line started there and ran through an existing pipe to northwest corner of the house and then a new trench was excavated and monitored that was 8’ long, 1’ wide and 2’ deep. No artifacts were recovered, or intact layers were visible in profiles. A report indicates that the north wall of the basement foundation was subjected to repairs. It is unclear how extensive these repairs were and what was the impact to the archeological record. Modern utilities exist and run to the main house.

While numerous excavations have occurred across the property especially on the north and south faces of the structure. It is unclear if intact cultural layers exist along the east and west walls of the Dudley Digges House.

Ballard House

The Ballard House was built c. 1709 is of the Colonial style of architecture. The house is one- and one-half stories, eighteen rooms with basement, two thirds length rear addition, frame covered with weatherboards, five dormers on front and three on rear, gable roof with cedar shingles. The building measures 3,768 square feet. The north end addition was not part of the original house but was constructed before 1800. A porch was constructed on the back in the 18th century and modified in the 19th century. The house is located on lot 54. The house was built between 1706 and 1709 by Edward Fuller. Upon Fuller’s death the house was transferred several times before John Ballard acquired it in 1727. Upon his death the house continued to pass through various owners and during the siege of Yorktown the building was damaged by shelling. In 1916 George Blow purchased the house and lot and it became a part of Blow’s estate Lee Hall. Blow remodeled the house in the 1920s. The National Park Service acquired the property in 1968 and restored the house in 1975. The house was until recently occupied as a residence by park employees.

The Yorktown Archeological/Historical Assessment (Grzymala 1998) identified a single substantial archeological project within lot 54. The project was organized by Norman Barka and Southside Historical Sites, Inc. in advance of the Bicentennial celebrations. The Phase III archeological excavations were conducted in the southwest and northwest yard areas of the Ballard House. The stated goal of the project was to locate and define any outbuildings or dependencies. The project identified four outbuildings including a kitchen which was built following the siege of Yorktown, sometime between 1781 and 1796. Additionally, a portion of the southwest yard included the backfilled remains of a British Battery.

While large scale Phase III excavations occurred on the Ballard House property they were mostly away from the house except along in the north and northwest (rear) side. It is unclear if intact cultural layers exist along the east and south walls of the Ballard House.

Smith House

The Smith House was built c. 1750-1751. The Smith House is built in Colonial architectural style. It is one and one-half story with cellar, thirteen rooms, brick Flemish bond with glazed headers, stone door and windowsills, gable roof of cedar shingles, four dormers on the front and two at the rear. The building measures 3,354 square feet. Lot 53, which is directly behind the Nelson House was purchased in 11706 by Lawrence Smith, who conveyed the property to his son, Edmund. Edmund never lived on the lot, but at some point, tore down his father’s house and was replacing it when he died as his Will indicates he gave the lot 54 property “whereon I am now building a house” to his daughter Mildred. Shortly after she married David Jameson, who was the Lt. Governor of Virginia in 1781. The property stayed with her husband until he died in 1793. During the 19th century the property went through several owners until it was purchased by George Blow in 1915, who remodeled and incorporated the property into his estate. The property was purchased by the NPS in 1968 and restored to its 1750s appearance in 1975-76. The property is currently used as employee housing.

The Yorktown Archeological/Historical Assessment (Grzymala 1998) identified a single substantial archeological project within lot 53. The project was organized by Norman Barka and Southside Historical Sites, Inc. in advance of the Bicentennial celebrations. The Phase III archeological excavations were conducted in the south/southwest yard area of the Smith Property. The goal was to locate18th and 19th century dependencies, pathways, garden areas, fence lines and to recover artifacts use by the former inhabitants of this lot. Only a small portion of the excavations occurred near the southwest corner of the Smith House. A 120 feet by 100 feet area was gridded and

While large scale Phase III excavations occurred on the Smith House property they were mostly away from the house except along in the southwest corner of the house. It is unclear if intact cultural layers exist along the remainder of the structure.

II. Purpose and Scope of Required Archeological Investigation The purpose of this intensive archaeological investigation study is to determine if archeological resources are present within the area that will be impacted by the exterior rehabilitation of the Dudley Digges House, Ballard, Smith, and Nelson Houses and to the extent possible, evaluate the significance of any deposits and/or features that might be discovered. NPS 28 defines the scope and goals of an intensive archaeological identification study:

An archaeological identification study locates archaeological resources and describes their characteristics, potential scientific value, and threats to their integrity and condition. Intensive-level surveys will collect and analyze sufficient data so that the location, characteristics, scientific values, and condition of archaeological resources and threats to them can be determined.

The information gathered from the investigations will be used to assist the park in meeting its obligations under Section 106 of the National Historic Preservation Act of 1966, as amended. In order to accomplish this goal, fieldwork consisting of the excavation of 50 shovel tests, 10 1x2m units, 10 1x1m units, artifact cataloging and curation activities, and project reporting and documentation will be required.

This project also has the potential to provide information on house residents at each of the historic houses within the project. The recovery of artifactual materials from the site will allow for a better understanding of how the site was occupied over time and shed light on the occupants that lived and worked in Yorktown.

The investigation will be conducted in accordance with the Secretary of the Interior’s Standards and Guidelines for Archaeology and Historic Preservation (48 FR 44716). The work also will meet those standards set forth in the Virginia Department of Historic Resources “Guidelines for Conducting Historic Resources Survey in Virginia” (2011, revised 2018). The investigation must be performed to all relevant Department of the Interior/National Park Service Standards and the Virginia Department of Historic Resources guidelines for conducting archaeological investigations.

In general, the baseline method for this portion of the project will consist of the excavation of shovel test units and excavation units, but other methods may be stipulated if project requirements warrant their use.

The Contractor shall provide all necessary professional services in the fields of geophysical exploration, archeological excavation and interpretation, collections management, and support services (i.e., administrative, fiscal, clerical) to prepare an archeological investigation report for the project area. The areas to be examined will be clearly marked by the NPS prior to the beginning of work. An NPS representative will be present at the site to orient the Contractor to the site and to the areas targeted for investigation. The Contractor will be provided with maps showing existing topographic features as well as available plans for the proposed project.

Pre-Fieldwork Tasks

· Attend a start-up meeting at the project site to discuss project logistics, site safety, schedule, and any other issues relevant to the successful execution of this scope of work. The meeting will also be conducted to lay out shovel test and excavation unit locations for the project. The meeting must be attended by the project principal investigator, the NPS Contracting Officer’s Technical Representative (COR), and other NPS personnel designated by the Colonial National Historical Park Superintendent.

· A detailed site safety plan must be prepared by the Contractor prior to initiation of on-site fieldwork. The contractor shall be responsible for contacting VA811 to identify the locations of any buried utilities that may be present within the project area. This must be done at least seventy-two (72) hours (excluding holidays and weekends) before fieldwork begins.

· Perform a program of background research adequate to interpret the result of the archeological investigation based on the requirements stipulated in the Commonwealth of Virginia, Department of Historic Resources guidelines for conducting of such investigations. Information collected during this background research process must be presented in the introductory sections of the project report, and may be further utilized in interpreting any archeological resources that may be discovered during the fieldwork phase of the archeological investigation. Data derived from the background research process may also be used in the development of management recommendations that will be presented in the concluding section of the project report.

In addition to planning and preliminary design documents that have been prepared specifically for the rehabilitation project, the NPS has compiled a series of reports that will be of use in the conduct of background research for this investigation. These include a Historic Structures Report, National Register Nominations, archeological reports a cultural landscape report, an archaeological overview and assessment, and a series of archaeological reports and management reports. All usual and customary sources for the preparation of background research sections for archeological investigations in Virginia must be consulted and cited during this portion of the project. Access to the Park library and archives will be available, and relevant reports, maps, and other documents therein will be discussed at the project start-up meeting. All other materials, documents, and supplies will be supplied by the Contractor.

Fieldwork The Contractor will provide the following fieldwork services:

Excavate 50 50x50 centimeter Shovel Test Pits (STPs) at intervals of no more than 5 meters (16.4 feet) within the area of potential effect. The Shovel Test Units will be fully excavated in natural stratigraphic layers to sterile subsoils, or 3 feet (ca. 1 meter) below the surface, whichever comes first. All soils will be dry-screened through ¼ inch hardware cloth to recover artifacts unless soil conditions warrant other treatment. The location of all tests will be accurately mapped. Any modification of research strategy, such as unit placement, size, etc. must be made in consultation with the project COR. Given the nature of the project areas and planned disturbance, the precise locations of STPs and EU’s to be excavated during this project will be determined by the service provider. Shovel test pits and excavation units must be placed in response to the overall sensitivity of the area, localized disturbance conditions, and the locations of potential disturbances. Any modification of research strategy must be made in consultation with the project COR.

Excavate 10 1x2 meter square archeological test units and 10 1x1 meter square archaeological test units (30 square meter units). The test units will be fully excavated to subsoil or 1.3 meters (4 feet) below the surface.

All excavation units will be of uniform dimension as indicated above and will be excavated by hand. Shovels may be used to remove dense fill soils but all features will be excavated using small hand tools such as trowels, spoons, etc. All soils will be dry screened through ¼ inch or finer hardware cloth.

The location of all archeological tests will be accurately mapped. Fill soils will be present in some portions of the project area. In such cases, only artifacts of special significance or from primary context need be collected. The decision to adopt this strategy must be made in consultation with the project COR.

Under no circumstances will any archeological investigation be conducted outside of areas of direct construction impact. Any modification of research strategy, such as unit placement, size, etc. must be made in consultation with the COR.

The following field records will be maintained: a catalog of field specimens where every excavated provenience is given a sequential number in the field; a photographic log; a list of features; and a daily record of the observations and procedures conducted by the on-site field supervisor (the latter will include Feature Recording Forms and Level Recording Forms). An accession number will be assigned to the Contractor which will appear on all field forms, photographs, artifact bags, soil samples, field notes, etc. All data, archival or artifactual, will bear this number from the point of collection in the field. At the end of field investigations, the Contractor will forward to the COR the field specimen (FS) catalog which will be used as a receipt for property, documenting the Contractors possession.

Soil types and Munsell color codes shall be referenced in soil and strata descriptions. Additionally, clear language shall be used to identify the different soils encountered, with particular attention to the depths/elevations at which fill layers, potential in-situ site deposits, and naturally deposited strata begin and end. A profile drawing will be prepared for each excavation unit.

Field photography shall be taken during the investigation in order to thoroughly document field conditions, significant areas of interest, crew activities, and profiles of EUs. All photographs taken must be processed archivally to meet NR standards.

Paper forms for the registration of sites into the Archeological Sites Management Information System (ASMIS) shall be filled out by the Contractor. Note: ASMIS is transitioning to and new site inventory system called the Cultural Resources Inventory System (CRIS). The ASMIS forms shall be supplied by the COR. New or updated state forms shall also be filled out by the contractor if archeological sites are newly discovered or modified and shall be included as an appendix to the final report.

Note: Flexibility in the placement of STP’s and excavation units will be required, and it is possible that greater or lesser level of effort will be required for each of the project elements. However, potential service providers should anticipate excavating all 50 STPs and 30 square meters of units identified in the preceding section.

Artifact Cataloging and Curation

· Recovered artifacts must be washed and cleaned as appropriate to the material. All of the artifacts collected shall be cataloged using ICMS and all data entered must conform to the standards and terminology used by the Northeast Region Archeology Program (NRAP). A flow chart and specific instructions for cataloging and storage of the artifacts will be provided. All material must be stored according to NRAP guidelines with archival quality tags. Gail Frace at NRAP (978 970-5151) shall serve as inspector for the cataloging, data entry, and storage requirements for the project. Artifacts must be directly labeled. All stable artifacts greater than 1/2 inch, and all diagnostic artifacts, that can be directly labeled without harming the artifact shall be directly labeled. If large quantities (e.g., more than 100 items) of fire cracked rock, architectural materials (e.g., windowpane fragments, mortar, brick, nails), or shell however comprise a significant portion of material recovered, then at least 20% of the items in the lot (both large and small) must be directly labeled.

· The service provider must provide evidence that personnel responsible for cataloging artifacts using the ICMS system have adequate training and experience to ensure successful completion of this task. If the service provider does not have trained personnel meeting NRAP’s standards, required training shall be provided by NRAP staff.

· Note: Contractor’s bids should anticipate the recovery of up to three thousand (3000) artifacts that will require cataloging, as well as project documentation. A selective sample strategy shall be employed whereby bulk materials, meaning brick fragments, coal, slag, iron or tin can fragments, large quantities of shell, fire cracked rock, roofing slate, mortar, and other architectural debris shall be selectively sampled for representative examples only. The remaining examples of such bulk materials shall be quantified, noted on the field forms, and discarded in the field.

· Original field notes, photographs, and other project documentation shall also be cataloged and directly labeled.

· At the completion of the project, all artifacts and supporting documentation (field notes and forms, maps and drawings, and other paper records, photographic records, and all other materials associated with project documentation) shall be transferred to the Park Curator at Colonial National Historical Park. All supporting documentation must also be prepared for curation and cataloged to National Park Service Northeast Region standards using the Interior Collection Management System (ICMS).

· All documentation returned to the Park shall be cataloged and housed to regional standards and returned to the NPS upon completion of the project. Please note the NPS does not consider digital files to be archival; therefore, photo processed copies of digital images greater than 3x5 inches is required. These shall also be cataloged and housed with the other archeological associated documentation. Folders, boxes, and other enclosures shall be supplied in a form acceptable for long-term archival storage. Paper records shall be supplied on archival-quality acid-free and lignin-free paper stock. If materials are reproduced, the original documentation shall be submitted with the reproduced copy.

· All recovered artifacts must be delivered to the Park in corrugated, vented boxes. The boxes will be of an acid-free composition, such as Hollinger Record Storage Boxes or an equivalent. Artifacts within the boxes must be packaged in labeled, vented zipper-sealed plastic bags. Artifacts must be packaged separately by ICMS catalog number, with an acid free label in each bag carrying the appropriate catalog number or individually marked, when physically possible and when the item count is small. Additional information regarding approved packaging materials shall be made available upon request.

· COLO accession numbers and COLO catalog numbers shall be assigned following NPS procedures.

Reporting The contractor for this project will be responsible for preparing a report that fully documents the archeological investigation and bulkhead description described within this scope of work. Specific report products required under terms of this scope are as follows:

· A management summary/interim report outlining the methodology and results of the Phase I and II testing to be delivered within two weeks of completion of all field investigations. This summary will highlight the results of the archeological investigation for management and design personnel. The management summary shall include adequate graphics to allow for interpretation of project results, and must contain a base map indicating the location of all shovel test units excavated during the project. It shall include general statements about the identified archeological remains and, if necessary, make recommendations for further treatment of cultural resources.
