RE: Addendum Report: Class I Cultural Resource Inventory for Amendments to Segments 5 and 7
and the D Tank Site for the Carlsbad Municipal Water District Phase III Recycled Water Project,
City of Carlsbad, San Diego County, California (ASM Project No. 20460)
Dear Ms. Dramko,
In 2013 ASM Affiliates Inc. (ASM) was subcontracted by Helix Environmental, Inc. to conduct a Class 1
cultural resource inventory for the proposed Phase III Recycled Water Project (Project) located in the city
of Carlsbad in the county of San Diego, California. The inventory included a literature and record search
conducted at the South Coastal Information Center (SCIC) and a search of the Sacred Lands Files of the
Native American Heritage Commission (NAHC). This study was completed in 2013 with the report
prepared and formally submitted in 2014 (Daniels and Becker 2014). Since the time of the original report
submittal there has been several segments appended to the original Project APE that this letter report will
now address as an addendum to the original study.
The results of original Class I cultural resource inventory can be found in the 2014 report Class I Cultural
Resource Inventory for the Carlsbad Municipal Water District Phase Ill Recycled Water Project prepared
by ASM Archaeologists James T. Daniels and Mark Becker. In summary, the results of the previous
report determined that all the identified cultural resources would be either avoided or were determined to
be not significant or mitigated to less than significant impacts by prior studies. Accordingly, this letter
report will only address the Class I Cultural Inventory results for the appended Project APE as the
potential impacts along prior proposed segments has already been examined in the original report. The
original 2013 SCIC record search data set was also re-utilized in the current study as the original record
search boundary included a quarter-mile search radius. A check of the appended Project segments shows
that none of the currently appended segments fall outside of the original quarter-mile search radius used
in the original report.
This investigation was conducted in compliance with CEQA Plus, which includes compliance with
Section 106 of the NHPA as well as CEQA. Section 106 is applicable to federal undertakings, including
projects financed or permitted by federal agencies, regardless of whether the activities occur on land that
is managed by federal agencies, other government agencies, or private landowners. The Phase III project
is in part funded by the State Revolving Fund for the California State Water Resources Control Board
(CSWRCB).
The goal of the inventory was to determine the location of previously recorded archaeological sites that
intersect and are directly adjacent to the proposed area of potential effect (APE) in an effort to make
appropriate recommendations on locations for archaeological monitoring along the proposed project APE.
This addendum to the original Class I Inventory was conducted to provide adequate information regarding

the previous work and previously recorded resources intersecting and immediately surrounding the APE
in accordance with CEQA-Plus,
PROJECT SUMMARY AND LOCATION
The Carlsbad Water Recycling Facility (CWRF) Expansion would be installed at the existing CWRF,
located at 6220 Avenida Encinas, Carlsbad, California 92011. The new or relocated storage tank would be
located at the existing "Twin D" tank site near the intersection of Poinsettia Lane and Black Rail Road.
Expansion Segment 5 (ES 5) lies north and south of State Route 78 (SR-78) along the
Carlsbad/Oceanside boundary, and along El Camino Real to Kelly Street. Expansion Segment 7 (ES 7) is
located south of SR-78, west of College Avenue, and northeast of Carlsbad Village Drive.
Implementation of the 2012 Recycled Water Master Plan (RWMP) is divided into three phases: Existing
(Phase I and Phase ll), Phase Ill, and Build-out. The proposed project, Phase lll, would expand CMWD's
recycled water system to the north area of Carlsbad and begin initial expansion into neighboring water
service agencies. The Phase Ill project components would be completed between 2014 and 2020. The
Phase III project would expand the treatment capacity from 4.0 million gal. per day (mgd) to 8.0 mgd
within the CWRF by installing additional filtration units and chlorine contact basins. The Phase III
project would also install 81,000 ft. of pipelines, relocate or construct a new storage tank, convert existing
potable water facilities to recycled water use, and retrofit landscape irrigation water systems to use
recycled water in eight expansion segment locations throughout the project area.
RESEARCH DESIGN AND METHODS
The present Class I study consisted of a formal request for records of previously identified cultural
resources and studies on file at the SCJC. The records search was completed on April 12, 2013. The
current investigation also included a request for the NAHC in Sacramento to conduct a search of the
Sacred Land Files, which was completed on April 18, 2013.
The resulting data has been used to assess:
• the extent of previously completed studies of cultural resources that intersect the currently proposed
appended Project APE;
• the number and character of previously recorded cultural resources intersecting the currently
proposed appended Project APE;
RECORDS SEARCH RESULTS
The records search conducted at the SCJC on April 12, 2013 was re-utilized for the current study as the
quarter-mile search radius applied in the original study is still adequate and applicable for the current
appended Project APE. A copy of the record search results from the SCIC is attached in Confidential
Appendix B of the original 2014 report (see Becker and Daniels 2014).

to be a Late Prehistoric temporary camp where mainly shellfish processing and seed grinding occurred.
The northwest portion of the site that was tested (which includes the currently proposed Tank D location)
was determined to be not significant by Gallegos & Associates (also see Daniels and Becker 2014).
MANAGEMENT CONSIDERATIONS
This investigation was conducted in compliance with CEQA Plus, which includes compliance with
Section 106 of the NHPA as well as CEQA. The appended project APE for the recycled water pipeline
and the 1.5-MG storage tank intersects a total of four previously recorded archeological sites. The four
sites intersected by this project are listed in Table 3. All cultural resources within the proposed appended
Project APE were determined to be not significant or mitigated to less than significant impacts by prior
studies. Therefore, the findings of this report conclude that there will be no adverse effects to historic
properties from the appended portions of the project which remains consistent with the findings of the
original 2014 report prepared by ASM, However, archaeological monitoring is recommended in all
areas that intersect known archaeological sites and a 100-ft. buffer surrounding them.

Sites SDI-6139, and CA-SDI-10025/13124 were identified as intersecting the proposed appended Project
APE of ES 5 (Figure 4 in Confidential Attachment B). SDI-6139 was originally recorded by Franklin and
Thesken in 1978 as a possible village site with a large shell, bone, ceramic, and lithic scatter, including
projectile points, flakes, ground stone, hammer stones, chopping tools, and a scraper. Historic-period
porcelain was also recorded. The site was revisited by Romani and Hawthorne in 1981, and they
suggested that the site was possibly an ethnohistoric village encountered by Portola in 1769. In 2010, the
site was revisited by Morgan and Tennesen of HOR to survey dirt access roads intersecting the site. They
identified some shell in the access roads, but vegetation next to the roads was dense and no other artifacts
were identified. Recon conducted an evaluation of the site, and based on the absence of site integrity and
limited artifact density and diversity, they determined the site was not significant.
SDI-10025 was recorded in 1978 by Ken Hedges, initially as W-133, as a general surface scatter of shell,
flaked stone, and fire-cracked rock, with the dense midden deposits having a very high shell content.
Three loci are identified within the site. The site was reportedly visited earlier by Malcolm Rogers, who
reported a sweat house associated with the site. Hedges was unable to re-locate this feature possibly due
to a massive earth cut in Locus A. The initial site record for SDI-13124 is the same site record prepared
by Ken Hedges from 1978 for SDI-10025. There is a scantly detailed site record from 1967 by Prewitt,
Allan, and Stahl that lists a bifacial mano, a core, four pot sherds, 24 flakes, a broken cobble fragment, a
unifacial hand stone, another possible hand stone, and some clear glass at the site. An ElR by Phillips
Brant Reddick documents that SDI-10025/13124 was severely impacted and no longer retains integrity,
and that no significant impact would occur from a 26 acre project that is now complete.
Expansion Segment 7
ES 7 consists of 4-in.-to 8-in.-diameter pipelines that will provide service to a homeowners association,
and existing school landscaping at MiraCosta College in Oceanside. The proposed alignment for ES 7
runs along Tamarack Avenue, Chatham Road, Andover Avenue, Bridgeport Lane, and Carlsbad Village
Drive.
SDI-5601 was originally recorded in 1977 as covering an area of 3 acres (Figure 4 in Confidential
Attachment B). Four concentrations of cultural material were noted, including ground stone and flaked
stone artifacts, fire-affected rock, and shell. A testing and data recovery program was conducted by Recon
on the south half of the site prior to the residential development, and impacts to the site were considered
mitigated to below a level of significance (Hector 1983 ). The northern half of the site was also recently
tested by ASM in 2011 and determined to be not significant.
Storage Tank D
An additional recycled water storage is proposed at the existing "Twin D" tank site. This will include
either constructing a new 1.5-MG steel tank adjacent to the two existing tanks or relocating an existing
1.5-MG steel tank to the site. Construction would include an at-grade concrete ring wall to support the
1.5-MG tank.
SDI-6819 intersects the proposed location for the storage tank (Figure 5 in Confidential Attachment B).
This site was first recorded in 1978 by Jay Thesken. The site reportedly consisted of three scrapers, one
core, two choppers, and two Tizon Brownware sherds, as well as a moderate scatter of shell on a gentle
contoured hilltop. In 1992, the northwest portion of the site was tested by Danielle Huey of Gallegos &
Associates prior to construction of several tanks and pads. The artifacts recovered included 27 pieces of
debitage, one retouched flake, one scraper, three cores, one core tool, one hammer stone, two hand stones,
nine hand stone fragments, one ground stone with battering, and 11 pot sherds. The site was determined
