HomeMy WebLinkAbout1998-08-03 City Council (21)City of Palo Alto City Manager’s Report TO:HONORABLE CITY COUNCIL FROM: CITY MANAGER DEPARTMENT: CITY MANAGER DATE:AUGUST 3, 1998 CMR: 332:98 SUBJECT:SAND HILL CORRIDOR IMPROVEMENT PROJECTS - APPROVAL OF A CONTRACT FOR CONSULTING ARCHAEOLOGICAL SERVICES This is an informational report and no Council action is required: BACKGROUND Stanford University (Stanford) has the obligation, under the Development Agreement approved by the City Council on June 30, 1997 and the voters on November 4, 1997 to undertake extensive archaeological study in the Sand Hill Corridor, have construction monitored for possible archaeological impacts and reimburse the City for an archaeological consultant to oversee Stanford’s archaeological work. City and Stanford staff have developed an approach whereby the City will contract with an archaeological consulting firm to undertake the required work. On May 21, 1998, the Finance Committee reviewed C~:243:98 ("Recommendation for Changes to the Proposed 1998-99 Budget to Implement the Sand Hill Corridor Improvement Projects") The staff report noted that a Request for Prop0sal (RFP)for Archaeological Consulting Services had been issued and the specific 1998-99 budget modifications would be brought to the Council in July 1998. On May 21, 1998, the Finance Committee concurred with having the consultant contract proceed directly to Council so long as the contract was not placed on the Consent Calendar. In June 1998, discussions with the City Attorney clarified that this contract (as well as the contracts for Senior Planner, Arborist and civil engineer) fall under provisions of the Palo Alto Municipal Code that provides for City Manager approval of contracts for land CMR 332:98 Page 1 of 4 development related specialized services that are paid for by a property owner/applicant. Since all costs incurred will be paid out of funds deposited with the City by the property owner, no budget action (i.e., inclusion in the regular City budget or approval of a Budget Amendment Ordinance) is necessary. DISCUSSION City and Stanford staff discussions in early 1998 identified a strong desire by Stanford to proceed with the required archaeological work in 1998. This direction is based on the objective of providing as much time as possible for the archaeological work and minimizing conflicts with future construction activity. Also, Stanford is proceeding this summer with demolition of the vacant former Children’s Hospital buildings because of deteriorating condition and attractiveness to vandalism. Removal of these buildings needs to be monitored by an archaeologist. Once the buildings are removed, it will be possible to undertake required archaeological investigation of the site including excavation of the remains of the Stanford house and outbuildings that~ were partially destroyed in the 1906 earthquake. City and Stanford staff agreed that the most expeditious way to handle the archaeological work was to have one consultant under contract to the City. The alternative is to have Stanford retain an expert and then the City retain a second expert to monitor the Stanford consultant, This alternative approach would have the potential for conflicting and confusing professional opinions. The consultant selection process started with City and Stanford staff meeting with the staff of the California Native American Heritage Commission (NAHC). A list of six potential consultants was identified. Initial contacts were made to determine interest in submitting a proposal, qualifications to do the work and potential conflicts of interest. Three consultants were asked to submit bids. Two of the firms submitted a joint proposal and the third firm also submitted a proposal. On Friday, May 29, the consultants were interviewed by a panel including staff from the City, Stanford University and the Stanford Management Company. The panel unanimously agreed that the proposal submitted by Pacific Legacy was the best proposal and a contract should be prepared. Pacific Legacy’s proposed budget was slightly lower than the competing proposal but the difference in cost was not a factor in the panel’s decision. The attached scope of services focuses on eight major tasks: 1.Archival Review and Preparation of an Archaeological Testing Plan; 2.Subsurface Testing and Evaluation; 3.Construction Monitoring; 4.Coordination with Native American Community Including Most Likely Descendant; CMR 332:98 Page 2 of 4 o 6. 7. 8. Excavation and Removal of Human Remains; Artifact Recovery Program; Submittal of Monthly Reports and Coordination; Submittal of Final Report. The consultant, City and Stanford will have an active process to meet and work with representatives of the Native American community. The contract calls for the involvement of Native American monitors during subsurface listing, artifact recovery work, excavation and removal of human remains and construction work. The contract budget is for $1,495,975 plus a $149,600 contingency. It is understood by the consultant, Stanford and the City that the final cost will depend, in significant part, on what is found during subsurface testing and evaluation and construction monitoring. If additional work beyond the contingency amount is required to satisfy the Environmental Impact Report’s mitigation measures, a contract amendment will be prepared. Under the terms of the Development Agreement, Stanford will deposit $250,000 with the City. As these funds are used to pay for consultant work, Stanford will provide additional funds to the City for future consultant expenses. RESOURCE IMPACT All expenditures under this contract will be paid for by Stanford University over the term of the contract. POLICY IMPLICATIONS Work done under this contract is consistent with the requirements of the City’s approval of the Sand Hill Corridor Projects. The contract does not involve any changes to City policies. TIMELINE Consultant work started on July 13, 1998 and will proceed consistent with the Scope of Services and construction activities. ENVIRONMENTAL REVIEW This contract implements approved mitigation measures in the adopted Sand Hill Corridor Project Final EIR. No subsequent environmental review or action is necessary.

SCHREIBER Deputy City Manager/Special Projects CITY MANAGER APPROVAL: / / JU~L cc:Pacific Legacy (John Holson) Stanford Management Company (Bob Reidy, Paula Kakimoto) Stanford University (David Neuman, Laura Jones) CMR 332:98 Page 4 of 4 SCOPE OF SERVICES: SAND HILL CORRIDOR ARCHAEOLOGICAL CONSULTING CONTRACT Task 1 - Sand Hill Corridor Project TASK 1 -ARCHIVAL REVIEI’V AND PREPARATION OF AN ARCHAEOLOGICAL TESTING PLAN Scope of Services Archival Review. Pacific Legacy will conduct a review of published and unpublished literature and archival sources relevant to the archaeology of the Sand Hill Corridor Project. These will be provided to Pacific Legacy by the Campus Archaeologist. These will include preliminary site reports, partial and completed laboratory analysis, student papers, theses, maps, field notes, site catalogs and photographs on file with the Campus Archaeologist. Pacific Legacy is also aware that the Department of Anthropology staff have excavated archaeological sites on the Stanford campus in conjunction with academic programs. These records, if available, will also be examined. Pacific Legacy anticipates that the literature, review will provide the necessary background for developing the archaeological testing plan (ATP). The ATP will include plans for archaeological rnonitoring and data recovery. Pacific Legacy assumes that for the project, large scale construction maps will be available for plotting all archaeological work completed with the project area. Pacif!’c Legacy will develop a catalog of all written material regarding sites in the project area in consultation with the Campus Archaeologist. PaciJTc Legacy will conduct a detailed field visit to become more familiar with the project area historic and prehistoric sites. Pacific Legaq/will also request appropriate available geotechnical reports to aid in identifying prehistoric or historic deposits in specific soils contexts. Completion of Archival Review and Proposal for Further Work. The archaeological testing plan will contain several elements. The plan will (1) identify gaps in existing. data, (2) ascertain which site areas have not been adequately sampled by previous subsurface archaeological investigations, (3) identify assessment strategies that may be necesgary to document site integrity and data potentials in those areas either not previously sampled (e.g., under existing buildings) or inadequately sampled. This section of the treatment plan will serve to focus data recovery efforts in areas that have high data potentials. The plan will serve to integrate existing i~fformation and conduct of the project over the term of the project. The plan will also include site-specific testing plans and methods consistent wi[h those defined in EIR mitigation measure 4.3.1(b). The plan, at a minimum, would discuss the following issues, (1) project description, (2) rationale for moving for~4"ard with the data recover}, effort, (3) summary of the results to date, (4) context for further evaluation, (5) research design, (6) methods, and (7) other information as appropriate. The ATP ,,viii also address the proposed data recovery at selected sites, mitigation monitoring program and inadvertent discovery plan. The monitoring section, at a minimum, will define (1) the mapped locations of known cultural resources, (2) the construction zones to be monitored, (3) archaeological monitor qualifications, (4) ’ notification procedures, (5) authority and protocols to halt construction activities, and (6) monitoring documentation procedures. The ATP will include an inadvertent discovery plan (IDP). The IDP will be the burial treatment plan developed in consultation with Campus Archaeologist, City, Native American groups and other interested parties. The IDP will include (1) notification and coordination protocols, (2) burial treatment policy and procedures, (3) assessments of significance and project effects, (4) collections methods, (5) report writing and records. management procedures and (6) an unanticipated discovery assessment/treatment schedule Deliverable: The Archaeological Testing plan will be a single document and will include following sections: (1) Project Description; (2) Status of CEQA Compliance; (3) Historic Context for Resource Evaluation; (4) Research Design; (5) Methods; (6) Native American Consultation Protocol, (7) Monitoring Plan and (8) Inadvertent Discovery Plan; and other information as appropriate. Assumptions: 1)The City and SMC will provide access to materials housed at Stanford University campus; 2)The City, SMC and Campus Archaeologist will assist Pacific Legacy in obtaining copies of all published or unpublished student papers, catalogs, maps, site records or other documentation regarding prehistoric and historic sites within the Sand Hill Corridor project; 3)Pacific Legacy will not publish any data regarding the Sand Hill Corridor sites without the prior written permission of the City, SMC and the University; and, 4)All materials written or otherwise collected for the Sand Hill Corridor project will comprise part of the curated collections of the project. Schedule: 90 days from Notice to Proceed Cost: see attached spreadsheet Archaeology Tasks - Sand Hill Corridor Project Page2of 21 Task 2 - Sand Hill Corridor Project TASK 2 - SUBSURFACE TESTING AND EVALUATION Implementation of the ATP(Task 1) will involve Phase I subsurface archaeological testing at appropriate sites, and preparing a Phase I testing report. It is recommended that a phased approach to site evaluation would be the most efficient and cost-effective way to proceed. In addition to more traditional archaeological methods such as hand excavation, our approach would entail using backhoe trenching and mechanical auger boring to determine site boundaries, integrity and site structure. Specific approaches to be employed at each site will be outlined in the ATP. Field methods will be designed according to extant information regarding the nature and data potentials of the sites in the project area., We assume an excavation rate of 1.0 m3 per day for a team of four workers given the nature of the soils in the Santa Clara Valley. Our estimates include both controlled and rapid recovery techniques (see below). We also have assumed approximately 25 meters of trench three meters deep can be excavated daily by backhoe. Lab time is estimated at about 35 percent of field time due to the volume of material expected from the sites for this phase. Work will focus on the Level I zone of sensitivity during this phase of the investigations. The actual Phase I scope of work will be better determinedafter preparation of the ATP. Table I presents Pacific Legacy’s best estimate of the level of effort and types of activities to be conducted at each site for the Phase I data recovery effort based on our meeting with the City, SMC and Campus archaeologist on June 9, 1998. Work projected at each site is based on available site records and field inspection of the sites. Pacific Legacy expects that most of the proposed work will be restricted to areas where construction footings or other subsurface construction features will be installed and to areas which have not been sampled previously: Subsurface exploration figures for each site (Table 1 - proposed action) are estimates and may change depending on field conditions, and the nature of archaeological discoveries. Pacific Legacy full), expects adjustments to the scope of work shown in Table I based on the results of Task 1. As can be seen from Table 1, our research in preparation of this proposal suggests that the majority of the Phase I data recovery work will be focused in the Stanford West Senior Housing area. This is consistent with EIR mitigation measure 4.3.1(c) in order to determine ifsignificant archaeological deposits lie within areas not explored previously. The majority of the work proposed will aid in determining whether features of the Gordon or Stanford estate lie beneath the Old Children’s Hospital. The archaeological work for the Stanford West Apartment area will focus on the southern edge of the sites likely to be impacted by construction. For the roadway sites, we suggest data recovery or minimal work for site boundary definition at two sites at which there has been limited archaeological testing completed. With the exception of CA-SCL-609, we Archueology Tasks - S:md l-lilt Corridor Project Page propose no work at the roadway sites because the data at hand seem adequate to knowledgeably manage the resources; The methods proposed for exploration of these sites should confirm whether significant deposits exist. While Table 1 indicates specific work techniques, these are only guidelines and will not be known until after Task 1 is completed. General Field Methods It is recommended that flexible strategies to evaluate sites would be the most efficient and cost effective way to proceed and still be in compliance with EIR mitigation measures. This may entail backhoe trenching or mechanical auger boring of a site area to determine integrity and site structure, as well as using more traditional archaeological methods such as hand excavation. Historical research will be completed for the historic sites in order to guide archaeological field studies. At sites where subsurface work is proposed, plotting areas of known previous disturbance, in consultation with the Campus Archaeologist and construction engineers, is recommended. Further, all previous subsurface investigation features should be plotted, based on existing data, in order to compile asingle reference map depicting disturbed portions of all relevant archaeological sites. Prior to the start of subsurface work, an intensive surface collection will be carried out at the sites, if appropriate. Artifact locations and surface concentrations of cultural materials will be marked and mapped. Surface distributions of artifacts and other cultural constituents may be informative for the placement of subsurface excavations. To determine rapidly if Undisturbed deposits exist within Level I sensitivity areas, a variety of subsurface exploration techniques are recommended. Mechanical trenching using a backhoe and small bucket (24" or less) is recommended at all sites. Trenching would take place at appropriate intervals in areas of exposed ground surface. The purpose of mechanical trenching wil! be to rapidly provide stratigraphic exposures to reveal the presence or absence of in situ cultural deposits and to delineate site boundaries. The nature of the soils, depth/thickness of cultural deposits, constituents, disturbance to site deposits and other appropriate observations will be documented. Use of a smaller grader or bulldozer is recommended to locate large historic features. This would only be done in consultation with the Campus Archaeologist. Color photographic prints (35 mm format) of stratigraphic exposures and soil profile drawings will be prepared as appropriate. Mechanical auger boring may be used to determine the presence or absence of cultural deposits in areas where mechanical trenching is not feasible. However, given the information already collected for the sites, auger boring would not be a significant component of the Phase 1 data recovery p~ogtam. For example, at CA-SCL-464, the Archaeology Tasks - Sand 11ill Corridor Pro.ject Page 4 of 21 density of materials collected from the peripheral area of the site is not great. It is our opinion that auger bores would be of little value in defining site margins because an adequate volume of soil cannot be recovered in order to capture sparse artifacts or other cultural constituents. Auguring may be valuable in locating buried, conspicuous culturally modified soils. If auger boring is conducted, bore samples will be excavated in 20 cm depths and soils will be screened to discover any cultural material. Constituent materials from auger spoils will be documented and/or collected. Exploration of potentially productive areas identified after surface inspection and gross exploratory methods normally would begin with the excavation of Surface Transect Units (STU). STU excavation is intended to determine artifact densities and generally proceeds in 10 to 20-centimeter lev.els. Due to the alluvial deposition noted in site records, during a site visit and in consideration of surface disturbance to the sites, it is likely, that this type of prospecting excavation rnethod would be used sparingly. Soils excavated from STU’s will be dry-screened through 3 or 6 millimeter mesh hardware cloth. Recovered cultural materials will be retained and densities noted to ascertain the variability in density of cultural constituents of deposits in sampled areas. More controlled techniques of excavation will be used in areas identified by surface inspection and excavation of STUs with high potential for recovery of materials. Rapid Recovery Units (RRU) will be used to quickly exposure soil profiles or to selectively recover cultural and other materials. Soils will be excavated in 20 or 40-centimet6r levels and screened using 6 millimeter screen mesh. Using a larger excavation increment and screen size would expedite inspection of a greater volume.of soil and would expedite the discovery and isolation of cultural features or productive strata. Formed flake tools, obsidian debitage, and faunal material would be retained in the field. Selective recovery of cultural remains may be performed, depending on the density, perceived redundancy of i~fformation, or stratigraphic integrity as determined in consultation with the Campus Archaeologist. Control Excavation Units (CEU) will be excavated in 10-centimeter arbitrary levels, unless cultural or natural stratigraphy dictates otherwise. All cultural materials will be retained from control units with the possible exception of abundant debitage from quarry sites. Soils front CEUs will be sifted using 3 or 6 rnillimeter mesh screen. In consultation with the Campus Archaeologist, wet screeningmav be conducted. All units will beexcavated [o a minimum of 10 centimeters below the cultural deposit, unless precluded either by impenetrable soil or geological formations, or a distinctive culturally sterile stratum has been reached. Soils will be loosened using shovels, trowels and other small hand tools, and dry screened through shaker screens fitted with the appropriate mesh hardware cloth. Flotation and carbon samples will be taken if appropriate. On completion of excavation units, a unit stratigraphic profile drawing Archaeology Tasks- Sand ttill Corridor Project Page 5 of 21 will be prepared. Excavated or surface collected materials will be placed in marked level bags, by level, and submitted to the field supervisor along with the level documentation at the end of each work day. Artifacts found in situ will be recorded separately and placed in individual bags within the unit level bag. All identified subsurface features shall be individually documented, photographed and mapped in both plan view or profile, as necessary. Black and white photographs and color slides (35-mm format) Will be taken during all phases of the investigations for all pertinent features, material concentrations and general work. Photo logs will be maintained and photographs catalogued. All photo processing will be done professionally, using standard and uniform formats. One contact sheet of each roll of black-and-white negatives will be made and properly identified. Black-and-white negatives will be submitted in numbered, flat, transparent plastic storage sheets. Each plastic storage sheet will be numbered and cross-referenced to a master index so that individual frames and sheets, may be located by individuals unfamiliar with the data. Some photography may be performed with digital still camera with images archived and reproduced electronically. Mapping of artifacts, features; mechanical trenching, and excavation units will be conducted from, or referenced to, a primary mapping datum at each site. This datum will be used to reference horizontal and vertical provenience control, locations of collected artifacts and excavation units. The datum point will be permanently affixed on, or set into, the ground so that it will not be altered or destroyed. Secondary datum points will be referenced to the primary site datum. To the extent possible, mapping references will be co-ordinated with construction engineering references. All distance, depth, and height measurements will be in metric unit measures. Existing planometric maps will be used as a base map for these investigations. The provenience of all sampling units will be tied into this base map and unique designations will be used for reference points. Mapping grid reference will be to true north where appropriate. The following records will be completed: (1) general site photographs taken before, during, and at the completion of excavation work; (2) daily excavation records and field notes for each unit and level; (3) feature records; and (4) field supervisor’s daily notes. When the excavation at a particular location has been completed, all screened dirt will be used to backfill the excavation unit. The EIR calls for a grid to be superimposed over each site, and this will be done using transit and stadia rod or similar equipment (e.g., electronic transit). Contiguous Archaeology Tasks- Sand Hill Corridor Project Page 6 of 21 excavation units will be designated in numerical order based on the type of feature encountered (i.e. rock feature, house foundation). Based on mapping provided by the Campus Archaeologist, existing planometric maps appear to be generally adequate for locating.features. Specific maps of cultural will be completed. Areal exposures, features, topographic information, burials and other information as appropriate will be recorded with bearing and distance from a known datum point or points. All Pacific Legacy personnel will meet the qualifications published in "Archaeology and Historic Preservation: Secretary of the Interior’s Standards and Guidelines," (Federal Register, Vol. 48, No. 190, September 29, 1983). Pacific Legacy’s field methods and compliance documents will follow the OHP guidelines published as Archaeological Resource Management Reports (ARMR): Recommended Contents and Format and Guidelines for Archaeological Research Designs. Schedule: To be determined after completion of Task I Cost: see attached spreadsheet Archaeology Tasks - Sand Hill Corridor Project Page q of 21 UU o ~ 0 Task 3 -Sand Hill Corridor Proj ect TASK 3 - CONSTRUCTION MONITORING Scope of Services Pacific Legacy is providing cost estimates for construction monitoring for the Stanford West Apartments, Stanford Senior Housing, Sand Hilt Road Extension and Related Roadway Improvements and Shopping Center project. Construction monitors will work with construction crews. The City has evaluated the archaeological sensitivity of the various construction areas and has determined the need for an archaeological monitor as indicated in the EIR. Pacific Legacy has budgeted for a total of 320 days for construction monitoring based on information provided in the EIR and RFP. We understand that the need for a monitor will be based on consultation with the City, SMC and Campus archaeologisL Prior to the initiation of construction or ground disturbiflg activities, SMC and the City will alert all construction personnel to tee possibility of buried cultural remains, advised of tee protocols for reporting discoveries, and instructed as to the authority of the monitor to halt demolition or construction in the vicinity of any significant discovery of prehistoric or historic resources. Upon discovery of a significant find, the monitor will immediately notify the Campus Archaeologist and Pacific Legacy’s Principal Investigator. The City, upon consultation with the Campus Archaeologist, SMC and the Principal Investigator will evaluate and mitigate in-tpacts to the find. Pacific Legacy routinely completes the daily field log for all of its survey, monitoring and excavation work. Example in our original proposal will be modified to suit the needs of the City. The archaeological monitor will also be responsible for completing a daily field log which will be retained on site while the monitor is there. Daily field logs will be included as an appendix to the monthly status report. The number of monitors present on a demolition or construction site on any given day will depend on the type, intensity an.d spatial distribution of activities being conducted and the archaeological sensitivity of the particular area. Determination of the appropriate number of monitors and level of monitoring effort will be done by Pacific Legacy in consultation with the City, SMC and Campus Archaeologist. Native American monitors will be included for work on the Sand Hill archaeological sites. Pacific Legacy has developed training programs for Native Americans which . includes recognition of archaeological features. We expect to hire from the local community and have worked with a number of Native Americans who have experience on the Star,ford Campus. We will consult with the City, SMC and Campus Archaedlogist regarding the 1-tiring procedures for the Native American monitors. The role and responsibility of the Native American monitors will be clearly defined in writing in the ATP. This would be completed in consultation with the City and the Archaeology Tasks - Sand HilI Corridor Project Page 1to1"21 Campus Archaeologist. Preparation of this document ahead of time could prevent costly construction delays that might otherwise occur while protocols and responsibilities are negotiated after a find has been made.

TASK 4 - COORDINATION WITH NATIVE AMERICAN COMMUNITY INCLUDING MOST LIKELY DESCENDANT Scope of Services Pacific Legacy has budgeted for consultation with the Native American community and the appointed Most Likely Descendent (MLD) for a two year period beginning in 1998. Beyond 2000 it is anticipated that coordination can be completed as part of Task 7, Monthly Reports. Pacific Legacy realizes the benefits of early consultation with interested Native American individuals and groups and will work with the Campus Archaeologist and the California Native American Heritage Commission (NAHC)to identify those groups. We have budgeted for two information meetings for interested parties. Initial contact will be via letter with a folloW-up telephone call prior to the informational meetings. For purposes of this proposal, the NAHC in Sacramento was consulted regarding potential Native American contacts in Santa Clara and San Mateo counties. Pacific Legacy will consult with the NAHC regarding any changes to the list once the Notice to Proceed has been issued. In consultation with the Campus Archaeologist, Pacific Legacy will provide the City with a contact list prior to any consultation. Pacific Legacy will consult with the designated MLD regarding any activities involving liuman remains or funerary objects. If buried human remains are encountered during any phase of construction, work in that immediate area will halt, and City and the coroner immediately notified. If the remains are determined to be Native American, then the NAHC will be notified within 24 hours as requiredby Public Resources Code 5097. The NAHC will identify and notify a designated MLD who will provide recommendations for the treatment of the remains within 24 hours. As required by Public Resources Code 5097.4(k), the NAHC will mediate any disputes regarding treatment of remains. When human remains are subsequently found, the City, SMC, Campus Archaeologist and coroner will be notified and if the remains are of a Native American, the designated MLD will be consulted within 24 hours. Pacific Legacy intends to provide opportunities for Native Americans who are interested and qualified, to participate in the excavation of human remains. Paci~’c Legacy will prepare a guidelines checklist for the City regarding co-ordination with the Native American comn-tunity at project milestones. This will also include a discussion of Native American issues and regulatory reporting requirement.s based on our discussions with the City, interested Native American and the Campus Archaeologist who has coordinated those activities on past projects. Schedule: Year 1998, 1999 and 2000 Cost: see attached spreadsheet Archaeology Tasks - Sand Hill Corridor Project Page 14 of 21 Task 5 - Sand Hill Corridor Project TASK 5 - EXCAVATION AND REMOVAL OF HUMAN REMAINS Scope of Services Pacific Legacy is well aware of the cultural sensitivities associated with removing human remains and will instruct crew members to treat remains with respect. We anticipate that human remains will be encountered. When human remains are found, Pacific Legacy will stop work at that specific location and notify the coroner, City, SMC and Campus Archaeologist as soon as possible. Prior to the start of fieldwork Pacific Legacy will consult with the City to determine proper communications protocols for notifying the coroner, the Native American Heritage Commission and/or the MLD as required by the EIR and state law. While protocols still have to be identified, we can offer a general program for treatment of human ren-tains after excavation. Specific procedures will be developed in the ATP. Proposed excavation methods for burial and/or features will be consistent with those developed in Task 1. Unit size will be dependent on the size of feature encountered. Soils will be loosened with hand tools, and dry screened tl~rough shaker screens fitted with the appropriate mesh hardware cloth. In the case of burials 1/8-inch mesh screen will be used as identified in the ATP. Flotation and carbon samples will be taken if appropriate. Human remains and funerary Objects will be kept apart from other archaeologically excavated cultural materials, midden constituents, etc. Excavated or surface collected materials will be placed in bags with provenience data clearly marked and submitted to Pacific Legacy’s field supervisor along with other documentation at the end of each work day. In sit~t artifacts wilt be recorded separately and placed in individual bags within the unit level bag. All identified subsurface features shall be individually documented, photographed and mapped in both plan view or profile, as necessary. Location reference will be to a permanent datum or subdatum. Black-and-white photographs and color slides (35-ram format) will be taken during all phases of the investigations for all pertinent features, material concentrations, and general work in the area of human remains. Photo logs will be maintained and exposures catalogued. All processing shall be done professionally, using standard and uniform formats. One contact sheet of each roll of black-and-white negatives will be made and properly identified. Black-and-white negatives will be submitted in numbered, flat, transparent plastic storage sheets. Each plastic storage sheet will be numbered and cross-referenced to a master index so that individual frames and sheets may be located by individuals unfamiliar with the data. Archaeology Tasks - Sand !fill Cm’ridor Pro.iect Page 15 of 21 If allowed by the MLD, we propose to conduct non-destructive osteological analyses on materials recovered. Dr. Hager will supervise the analysis at our Albany office. We have attached the forms in our original proposal we intend to use for the initial bone inventory, cranial measurements, posbcranial measurements, dental measurements and non-metric traits. In general, all materials (human remains and associated artifacts) will be cleaned only to the extent necessary to permit analysis. Burial associated grave goods will be kept with the individual remains and retained in clean archive boxes. The MLD is encouraged to visit our lab should they decide to do this. Unless specifically authorized in writing by the MLD, no destructive studies Of human bone will be undertaken and human remains shall not be analyzed beyond basic identification and non-disturbing recordation procedures in the field. The attached budget is to complete dating of the remains using the Accelerator Mass Spectrometry (AMS) tecl-mique. This is a destructive technique for dating of bone material which includes bone collagen extraction should such analyses be permitted. We also propose to analyze the material for C13/12 stable isotope ratios to determine, if possible, any dietary implications. This is completed in conjunction with the AMS dating. We plan to use Beta Analytic for this analysis. Non-destructive X-ray fluorescence spectrometry is proposed to determine the source.of any obsidianfound with human remains. We also would propose to measure the obsidian hydration rind on obsidian specimens. This is a destructive technique that, at a minimum, would leave a cut in the body of the artifact. Any proposed destructive analyzes would have to be approved by the Most Likely Descendant. Paci~c Legacy realizes that the excavation of human remains is a very sensitive issue and will abide by the wishes of the MLD. We have based our budget on the example given in our original proposal and the assumption of MLD concurrence with our approach. The budget proposed assumes that four person days are required to complete the excavation of one set of human osteological remains. Schedule: To be determined based on when human remains are encountered. Cost: See attached spreadsheet Archaeology Tasks - Sand Hill Corridor Pro.ject Page t6 ot" 21 Task 6 - Sand Hill Corridor Proi ect TASK 6 ’ ARTIFACT RECOVERY PROGRAM Pacific Legacy views this task as a Phase 2 data recovery program and for which additional work may be defined after Task 2 has been completed. Site-specific approaches are not offered at this time because the formulation of such are dependent on the results of Tasks I and 2. Methods to be used for this task have been explicated as part of Task 2. Anticipated analytical studies, curation and cataloging can be found in Task 8. The research design guiding the additional studies will have been written in Task 1, development of the ATP. For purposes of this proposal, we have based our budget for this task on the assumption that 150 m3 of cultural deposit (historic and prehistoric) will have to be examined. We assume that per day, a team of four excavators wil! be able to process 1.Ore3 of soil in the field. We have also included time for processing of materials associated with features consistent with those collected during. University sponsored testing as requested by the Campus Archaeologist. Schedule: To be determined based on Tasks I and 2 Cost see attached spreadsheet Archaeology Tasks - Sand Hill Corridor Project Page 17 of 21 Task Order 7 - Sand Hill Corridor Project TASK 7 -SUBMITTAL OF MONTHLY REPORTS AND COORDINATION Scope of Services Several levels of reporting will be completed by Pacific Legacy under this contract. Records will be kept on a daily basis which will include, at a minimum, date, work location, duties performed, crew roster, time reported in and out, visitors and their affiliation, vehicles, work area, discoveries, observations, problems and attachments such as supplementary reporting forms or accident reports. The daily record form will be completed for all phases of archaeological activity conducted for the SHCP. These will be mailed monthly with a written report to the City and SMC. Within six days after the month end, Pacific Legacy will prepare a brief letter report detailing the results of the previous month’s work on the project. Pacific Legacy understar~ds that this letter report will include a description of work accomplished by phase, work completed and a summary of any significant findings. Daily logs will be appended to the letter report.. We assume that there will be meetings or other reporting efforts over the four year term of the contract. We have budgeted to coordinate with the City, SMC, Campus Archaeologist, Native American groups, the MLD, the NAHC and others as appropriate. This may include meetings, work progress inquiries not covered in monthly reports and conflict resolution~ Schedule: 1998,1999,2000,2001 Cost: see attached spreadsheet Archaeology Tasks - Sand HilI Corridor Project Page 18 of 21 Task 8 - Sand Hill Corridor Project TASK 8 - SUBMITTAL OF FINAL REPORT Scope of Services We propose to begin compiling the final report in 1999 with completion 180 days after the field components of the project are ended. We estimate that this will be mid-year 2003 based on the schedule provided by the SMC. Pacific Legacy will start preparing sections of the report after a particular component of the project is completed. In this w.ay, writing will be conducted concurrently as other components of construction move forward. Pacific Legacy’s compliance documents will follow the State Office of Historic Preservation (SOHP) guidelines published as Archaeological Resource Management Reports (ARMR): Recommended Contents and Format, CEQA Guidelines Appendices K and G, and the Secretary of the Interior’s Standards and Guidelines. The report will include results of all phases of the project including Phase I and Phase 2 data recovery, inadvertent discoveries, monitoring efforts and removal of human remains. Pacific Legacy understands that the results of previou~ Stanford excavations in the project area will be integrated into the report. Graphics, photographic plates, illustrations and mapping will be included as appropriate. One of the largest tasks to be undertaken will be the analysis and cataloguing of collected materials from previous Stanford excavations and the current project for discussion in the final report. We assume that cataloging, preparation for curation and analysis will be completed under this task for materials from the Stanford collections and those collected during construction of the project. All collected materials will be cleaned as appropriate, sorted by class for material identification, briefly described and cataloged with an accession number. Collected materials will be assigned a prefix and numbered sequentially consistent with the requirements of Campus Archaeology Curation Facility, the intended curation facility. Materials cataloged by lot (i.e., debitage, or/and flake categories) will be given an alphabetical designation if selected for special analysis. The data base and catalog will be structured to include, at a minimum, the accession number, material Class (i.e., bone, shell, stone), provenience by unit, depth and feature, count, weight in grams, and a section for remarks. Individual artifacts will be measured, weighed, and described. Measurements for prehistoric materials will use the metric scale. This is somewhat different then the current Stanford University cataloging but is transferable to the Excel .catalog program developed by Pacific Legacy. In preparation for this proposal, conversations with Dr. Jones suggested that not all materials were cataloged but rather were prepared consistent with the research objectives of the particular project. Pacific Legacy will consult with Dr. Jones regarding the most expedient way to catalog the extant Stanford collections. Archaeolog.v Tasks - Sand Hill Co~ridoi" Pro.iect Page 19 of 21 Approximately 119 boxes of materials have been retained by Stanford from sites CA- SCL-287, CA-SCL-464, CA-SCL-584, CA-SCL-586, CA-SCL-591, CA-SCL-623 and CA- SMA-263. We assume that materials from the Stanford excavations at CA-SCL-613 will not need cataloging (cf. Jones 1997) and will involve minimal data integration into the final report..We assume that some level of cleaning, cataloging and analysis will have to be conducted on approximately 65 percent of the materials from the existing SHCP collections now housed by Stanford. After cataloging and preliminary identification has been completed, the types of analytical studies to be performed are based on the anticipated recovery of artifact classes described in the site records, preliminary reports and catalogs provided by the Campus Archaeologist to Pacific Legacy. These are discussed below. Time-Sensitive Artifacts. Chronologically sensitive artifacts (e.g., projectile points, shell beads) will be classified following established regional typological schemes. Debitage/Formal Tool Analysis. Analysis of debitage and formal tools may delineate production and manufacturing trajectories. It is expected that chert wil! dominate the debitage assemblage. Debitage counts and weights will be sun-tmarized by unit, depth and materials type. The results shall be segregated by screen size used. Where possible, flaked stone tools will be discussed in terms of accepted Bay Area regional typologies. Technological analysis, if appropriate, will be conducted to identify and describe the flaked stone tool technology(ies) observed in the collection. Tool distributions will be Summarized by unit and depth. The distributional data will be used, at a minimum, to assess deposit mixture, define assemblage and component constituents, and infer the functional nature of site components. In selecting specimens for obsidian hydration and sourcing, consideration will be given to inferred flaked stone technologies and manufacturing processes to ensure that the data requirements of specific research questions are satisfied to the fullest extent possible. Battered and Ground Stone Artifacts. It is anticipated that materials such as pestles, handstones and mortars may be collected. Where possible, battered and ground stone artifacts will be classified and discussed in terms of accepted regional types. Distribution data will be used to, at a minimum, assess deposit mixture, define assemblages and components and infer the functional nature of site components. Obsidian Source Determination. XRF spectrometry will be used to distinguish obsidian sources that cannot be confidently assigned to a source by visual techniques. It is anticipated that a mixture of Sierra and North Coast ranges obsidian will dominate the debitage and flaked stone tool collectior~. Pacific Legacy can complete these studies in house, Obsidian Hydration Rim Analysis. Obsidian hydration rim analysis will be conducted Archaeology Tasks- Sand t lillCorridorPrtLiect Page 20o1" 21 on formal tools, and, if appropriate, on a sample of debitage from each site. If appropriate, source specific obsidian hydration rim readings will be discussed with regard to proposed relative and/or experimentally derived hydration dates which have been developed (Origer 1982; Tremiane 1989). Rim readings will be used in conjunction with other data to assess deposit mixture, define assemblage components, and infer the functional nature of site components. Faunal Analysis. Fragmentary large and small mammal bone, shell and fish bone are anticipated to make up the majority of collected faunal materials. Faunal specimens of sufficient size will be identified to genus, species, element and condition whenever possible. Any bone modification (e.g., cut marks) will be described. Analysis shall include description, quantification, and interpretation of identified remains. Floral Analysis. We have budgeted for up to 50 samples to be processed for floral seed identification for all tasks. Pacific Legacy proposes to use Dr. Juila Hammet as a subconsultant.
