Monitoring excavations were conducted on Febmary 3-6, 9- 10, 24, 27, and March 2, 2009. The purpose of the monitoring was to identify and appropriately manage any culmral deposits that might be encountered during the excavation of the entry and exit pits for the micro-mnneling phase of the project. During the monitoring, only scattered marine shell (Chione sp. and Argopecten aequisulcatus) and a charcoal fleck were encountered. No further work is recommended. INTRODUCTION The North Agua Hedionda Interceptor Western Segment Realignment Project area is located on the northern shore of Agua Hedionda Lagoon, east of Interstate-5, in Carlsbad, Califomia (Figures 1 and 2). The project is shown on the USGS San Luis Rey 7.5' quadrangle, in an unsectioned portion of the Agua Hedionda land grant. The project involves the installation of a forcemain pipeline, utilizing micro-tunneling methods. Prehistoric archaeological site CA-SDI-13701 has been identified as being located, in part, within the project area. Project components proposed to impact SDI-13701 consist of mechanical excavations for entry and exit points of micro-tunnel pits. Archaeological testing at SDI-13701 concluded that the portion of this resource within the project area does not represent a substantial, intact deposit that might contribute to any potential eligibility of die site for the California Register of Historical Resources (Guerrero and Gallegos 2003, 2007; Iversen et al. 2009). A second deposit in the project area, NAHI-S-1, was provisionally identified as an archaeological site, but subsequent testing determined that it represented cultural material (marine shell and flaked lithic debitage) in a secondary, redeposited context.

The purpose of this investigation is to comply with the Califomia Environmental Quality Act (CEQA), and any otiier applicable federal, state, or local laws, ordinances, mles, regulations, and policies, prior to constmction activities. ARCHAEOLOGICAL CONTEXT The project area is located adjacent to Agua Hedionda Lagoon, tiie esmary of San Marcos Creek that was drowned by the post-Pleistocene rise in sea level. Geologically, Eocene marine sedimentary rocks underlie the location. This section presents an abbreviated sketch of tiie culmre-historical sequence recognized in the region. The San Dieguito period encompasses human occupation of the San Diego area prior to 7500 Before Present (B.P.). Defining characteristics of tiie San Dieguito artifact assemblage include distinct scrapers, bifacial knives, and crescent shaped eccentrics. The artifact assemblage is tiiought to represent a heavy emphasis on hunting of game (Meighan 1954; Moriarty 1966; Rogers 1939, 1945; Tme 1958, 1966, 1970; Warren, 1966, 1967, 1987; Warren and True 1961; Warren etal. 1961). The La Jolla period, followed by a hiatus/transition, encompasses a time frame between approximately 7500 B.P. and 1300 B.P. The La Jolla period is tiiought to represent an emphasis on littoral resources, as indicated by dense shell midden sites. The tool assemblage is defined by simple stone cobble tools and an increased emphasis on ground stone unplements (Gallegos 1985, 1987, 1992; Meighan 1954; Moriarty 1966; Rogers 1939, 1945; Tme 1958, 1966, 1970; Warren 1967, 1966, 1987; Warren and Tme 1961; Warren et al. 1961). The Late Prehistoric period, extending from tire end of the La Jolla to the beginning of the historic period, is typically assigned a range of dates from 1300 or 800 B.P. to 200 B.P. The Prehistoric Periods is often broken down into various subdivisions; Yuman Culmre I-III for tiie San Diego County coast (Rogers 1939, 1945); San Louis Rey-Luiseno periods for the nortii interior, and the Cuyamaca-Diegueno periods for the soutii interior, (Meighan 1954; Tme 1958, 1966, 1970); and Yuman and Shoshonean periods (Warren 1968). The Late Prehistoric Period is thought to include the introduction of the bow and arrow, use of pottery, and a tiieorized emphasis on inland plant resources (Meighan 1954; Rogers 1945; Tme 1958, 1966, 1970; Tme and Waugh 1982; Warren 1964, 1968). The historic period in coastal San Diego County was formally initiated in A.D. 1542, witii tiie arrival of the maritime expedition of Juan Rodriguez Cabrillo. However, substantial impacts may only have begun in 1769, witii tiie overiand party under Caspar de Portola and Jum'pero Serra. Important influences reaching tiie study area began witii tiie establishment of a mission and a presidio in San Diego and with frequent overland treks nortii from San Diego along tiie coastal plain. Additional missions were established at San Juan Capistrano (1776) and San Luis Rey (1798). After Mexico won its independence from Spain in 1821, tiie issuance of private April 15, 2009 Ken Victorino Page 3 of 8 land grants greatiy increased, including Agua Hedionda Rancho, created in 1842. Annexation of California to tiie United States in 1848 and the gold rush in northern Califorma tiie following year greatly increased the rate of settlement and of social and culmral change in the region. Cycles of boom and bust ensued during tiie late nineteenth cenmry, while growth was more persistent tiirough tiie twentieth cenmry. The city of Carlsbad was incorporated in 1952. THE MONITORING EFFORT, OBSERVATIONS, AND RESULTS The archaeological monitors for tiiis project were Shane Wetherbee and Arnie Schoenberg. Dr. Mark Becker, Principal Investigator, managed tiie monitoring effort for ASM. Tommy Herrera of Native Grounds participated as a Native American monitor. Don Laylander assisted in writing tiie report. ASM monitors oversaw vegetation removal, grading, silt fence installation, backhoe trenching, and drilling operations above bedrock, checking for archaeological resources, on Febmary 3-6, 9-10, 24, 27, and March 2, 2009. The only culmral evidence identified by ASM during archaeological monitoring consisted of sparsely scattered marine shell {Chione sp. and Argopecten aequisulcatus) and a charcoal fleck. CONCLUSIONS ASM did not identify any substantial cultural deposits during archaeological monitoring of constmction activities for the North Agua Hedionda Interceptor Western Segment Realignment Project. As a result, ASM does not recommend any additional work for this project. Sincerely, Mark S. Becker, Ph.D., RPA Principal Investigator Attachments: Maps Figure 1. Project vicinity map Figure 2.
