SCOPE OF SERVICES
AMENDMENT NO. 2
SCOPE OF WORK
Task 1: Delineation of the Area of Potential Effects (APE) and Completion of the
Archaeological Survey Report (ASR)
The APE will be delineated in consultation with the City. This will require meetings to review
construction plans and possibly a field visit to assess potential impacts. The APE, which must
be approved by Caltrans, will include areas of direct ground disturbance and any buffer areas
necessary to effect avoidance. The draft APE map (on 1 :lo0 scale project base maps) will be
included in the draft ASR, in accordance with Caltrans' standards.
The ASR will provide the results of the literature review, records search, and archaeological
survey, all of which have already been completed as part of Amendment No. 1. Under Caltrans'
guidelines, a positive.ASR is required when archaeological sites are within or immediately
adjacent to the APE. Portions of two previously recorded sites may be impacted by the
proposed interchange widening at La Costa Avenue: CA-SDI-603 on the western side of the
freeway, and CA-SDI-12,130 on the eastern side. As discussed below, an Extended Phase I
investigation will be necessary at these sites to determine whether they will be affected. The results of the Extended Phase I will be included in the ASR.
Task 2: Extended Phase I Investigation
Under Caltrans' guidelines, Extended Phase I investigations are used to determine whether a
subsurface deposit is present in the APE. If such deposits are present and cannot be avoided, a Phase II investigation is usually required in order to assess the significance of the site relative
to the National Register criteria. . Both of the archaeological sites in the La Costa Avenue
Interchange project have been impacted by previous construction activities. This makes it
impossible to determine the presence or absence of potentially significant subsurface deposits
by surface investigation alone.
Accordingly, the primary goal of the Extended Phase I investigation will be to sample the
subsurface components of each site to determine whether cultural materials maintain integrity.
If subsurface materials are found to be secondary deposits resulting from previous construction
activities, they are unlikely to qualify as a significant resource, and a Phase II investigation would not be warranted. On the other hand, if subsurface deposits are found which appear to remain
in their primary context (i.e., have not been moved or severely disrupted by previous
construction), a Phase I1 investigation would probably be necessary. This scope does not
include a Phase I1 investigation.
At CA-SDI-603, two questions must be addressed by the Extended Phase I1 investigation:
1. Is the cultural material observed along the face of the cut-bank above the southbound on-ramp between Stations 1683+30 and 1688+30 truly a secondary deposit as we
currently believe?
1
0 0
2. Will construction along La Costa Avenue between Stations 1683+20 and 1685+50 affect
cultural deposits which retain integrity? A shell and artifact scatter was observed on both
sides of the street, but there was evidence that the upper portion of the cultural deposit
had been removed during previous construction. It is uncertain whether existing material
in the APE retains sufficient integrity to be of archaeological value.
The field investigation at this site will include approximately 18 shovel test pits in the APE where
cultural material was observed on the surface. It is anticipated that the shovel test pits will be
deployed as follows:
1. Cut-bank along the southbound on-ramp: This area is about 500 feet in length. Five
shovel test pits are planned, spaced at approximately equal intervals.
2. North side of La Costa Avenue: This area is approximately 200 feet in length. Four
shovel test pits are planned, to be placed at approximately equal intervals.
3. South side of La Costa Avenue: This area is approximately 250 feet in length. Five
shovel test pits are planned, to be placed at approximately equal intervals.
If potentially intact cultural deposits are found during the course of shovel testing, 1 x 2 meter
controlled text units could be used to better examine the integrity of the deposit. Since test units
are viewed as a contingency, they are not included in this scope.
At site CA-SDI-12,130 on the east side of the freeway, the Extended Phase I investigation will
inciude ten shovel test pits between Stations 1665+00 and 1688+00. These will be placed
between the existing right-of-way fence and the edge of the existing 1-5 pavement (including the
northbound off-ramp) at approximately equal intervals.
Shovel test pits will be manually excavated. Excavated soils will be screened through 1/8th inch
mesh to optimize artifact recovery. Shovel test pits will be mapped onto 1 :I 00 scale project base
maps using tapes and compasses. Shovel test pits will measure approximately 30 centimeters
by 30 centimeters and will be excavated to sterile soil or to a depth of 50 centimeters, whichever
comes first.
Recovered artifacts will be cleaned and cataloged. Temporary curation will be provided until an
appropriate permanent curation facility can be identified.
The ASR will include the results of the Extended Phase I investigations at both sites. The
preliminary draft ASR will be submitted to the City for review and will be accompanied by
recommendations as to whether a Phase I1 investigation is needed. The draft ASR will
incorporate the City’s comments and will be submitted to Caltrans. Following receipt of Caltrans’
comments, the final ASR will be prepared responding to those comments.
Task 3: Staking of Sensitive Area Boundary and Survey of Driveway
Archaeologists will place twelve, three-foot wooden lathe along the limits of cultural deposits which are to be avoided. Additionally, archaeologists will conduct a survey of the proposed
private drive south of La Costa Avenue. The results of these two activities will be included in the
final ASR.
2
p 0 e
Task 4: Historic Property Survey Report (HPSR)
Archaeologists will prepare an HPSR summarizing the previous studies in order to identify the
historic properties potentially affected by the project. The HPSR will be positive, indicating that
site CA-SDI-603 is eligible but that the project will have no effect on the site. Per Caltrans’
comments on the earlier studies, the Area of Potential Effect (APE) will be revised and project
Stages 1 and 2 will be combined. The Scope of Survey will be as follows:
1. Revise ASR and Extended Phase I maps: Caltrans has required that the Stage 1 and
Stage 2 project maps be combined and that references to the APE be changed to study
area. In response to this requirement, KEA will prepare revised cultural resources survey
and excavation maps, utilizing a base map to be provided by Boyle.
2. Include proposed off-site private driveway connecting Parcels 21 6-060-52 and 21 6-060-54
survey in project documentation: The ASR and Extended Phase I reports must be revised
to include the driveway survey that was conducted after Caltrans’ review of these reports.
These reports will be submitted first to the City of Carlsbad for review and subsequently
to Caltrans. Any additional City or Caltrans comments will be addressed. The final
reports must also be submitted to the South Coastal Information Center for curation.
3. Prepare draft HPSR: This document summarizes the previous reports. In addition, it
contains necessary Section 106 compliance information, including discussions of
resource significance and project effect. It is assumed that through redesign, no
potentially significant resources will be affected by the project. The HPSR must contain
sufficient documentation to support this position. An inadequate HPSR could result in the
need to evaluate the two archaeological sites that are adjacent to the HPSR.
4. Prepare final HPSR: The draft report will be sent first to the City of Carlsbad for review.
After addressing the City’s comments, KEA will prepare a Caltrans review draft. After
receiving Caltrans’ comments, KEA will prepare the final HPSR.
