The Project is designed to address multiple water quality targets outlined in the MRP as well as solid waste (trash) discharge reductions under the MRP requirements. The proposed Project involves the installation of a drop inlet, diversion channel, and inlet junction structure (trash screen) in the upper and western end of the Colma Creek channel and Park boundary and a series of storm pipes and pretreatment chambers that lead to an underground stormwater storage reservoir in the southeastern corner of the Park underneath a portion of two baseball fields. A portion of the underground stormwater storage reservoir would function as a cistern holding water for future non-potable irrigation and the remainder would function as an infiltration chamber. The proposed Project Area of Potential Effects (APE) includes the horizontal and vertical extent of all temporary and permanent topographic modifications. Ground disturbances associated with the proposed Project will extend at least 10 to 12 feet below the existing ground surface. An archaeological literature and records search was conducted at the California Historical Resources Information System (CHRIS) Northwest Information Center (NWIC), Sonoma State University for the proposed Project APE, in November 2018. Over 30 investigations have been undertaken within an area extending 0.5-mile from the proposed Project APE; two of these evaluated a portion of the proposed Project APE. Three archaeological resources are located within 0.5-mile from the proposed Project APE, but no resources are recorded within the Project APE. A Phase 1 archaeological survey (i.e., an intensive, pedestrian ground surface survey) of the proposed Project APE to assess the presence/absence of cultural resources on the ground surface was conducted on January 4, 2019. No prehistoric or historic-period cultural resources were identified, but the potential for unknown subsurface resources that could have been buried by Colma Creek alluviation over the past 10,000 years was determined. Therefore, an Extended Phase 1 Archaeological Excavation including fourteen (14) 2-inch diameter geoprobes was completed to depths between 3.05 and 4.00 meters (10 and 13 feet) below surface throughout the proposed Project APE between March 12 to March 14, 2019. The geoprobes were excavated between 30- and 60-meters (98.5 and 197 feet) apart and were continued until the maximum depth of disturbance was reached. All excavations were supervised by Wood Senior Archaeologist Ken Victorino, RPA. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT iv The current Extended Phase 1 Archaeological Excavation did not identify any prehistoric and historic-period archaeological materials. Intact top soils within the proposed Project APE represent episodes of repeated flooding along Colma Creek or a related creek channel that regularly meandered over time. These intact alluvial soils indicate that ground surfaces within the proposed Project APE were not occupied throughout prehistory or since Euro-American settlement. Therefore, the proposed Project will not have significant impacts on cultural resources and no further archaeological measures including construction monitoring are necessary. In the unlikely event that unanticipated cultural resources are encountered during proposed Project activities, all work shall stop until a qualified archaeologist can evaluate the nature and significance of the find. In the highly unlikely event that human remains are discovered during proposed Project activities, State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made the necessary findings as to the origin and disposition of the remains pursuant to Public Resources Code Section 5097.98. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 1 1.0 INTRODUCTION The proposed Water Capture Project (Project) is a water quality improvement project within Orange Memorial Park (Park) in the City of South San Francisco, California (Figures 1 and 2). Ground disturbances associated with the proposed Project will extend at least 10 to 12 feet below the existing ground surface. This report documents the background research, Phase 1 Archaeological (ground surface) Survey, Extended Phase 1 Archaeological Excavation, and Native American consultation conducted for the proposed Project by Wood Environment and Infrastructure Solutions (Wood E&IS) Cultural Resources Manager David Stone, RPA, and Wood E&IS Senior Archaeologist Ken Victorino, RPA. Mr. Stone has more than 35 years of experience managing all phases of cultural resource investigations throughout California. Mr. Victorino has more than 22 years of experience conducting all phases of cultural resource investigations throughout California. 2.0 PROJECT LOCATION AND DESCRIPTION The proposed Project Area of Potential Effect (APE) is located within the Park, between West Orange Avenue and Chestnut Avenue, just east of El Camino Real, in the City of South San Francisco, on the San Francisco South, California U.S. Geological Survey (USGS) 7.5’ topographic quadrangle (see Figure 1). The proposed Project APE is located within approximately 1.5 acres of the 28-acre Park, along the Colma Creek channel, within the southern half of the Park (Figure 3). The City of South San Francisco is proposing water quality improvements within the Park that would capture and divert water flows from Colma Creek to the two existing ballfields for treatment and reuse to satisfy local irrigation demands. The proposed Project includes the following improvements (see Figure 2): • Drop inlet, diversion channel, and inlet junction structure (trash screen) in the upper and western end of the Colma Creek channel and just outside of the western Park boundary, within the Cal Water Property (Southern Greenhouse Parcel) south of Colma Creek; • 24-inch, underground storm drain pipe that extends from the Cal Water Property (Southern Greenhouse Parcel) south of Colma Creek, parallel to the creek channel, through the picnic area to the southeastern end of the Park; • A series of pretreatment chambers leading to an underground stormwater storage reservoir within the baseball fields in the southeastern portion of the Park; • Irrigation pump, water quality equipment shed, and irrigation within the picnic area; and • Regrading of the southernmost portion of the Park, within the baseball fields.

Ground disturbances associated with the proposed Project will extend 10 to 12 feet below the existing ground surface. 3.0 BACKGROUND 3.1 Environment Existing development within the proposed Project APE consists of park facilities including baseball fields and open picnic areas. A small portion of the proposed Project APE is located just outside of the western Park boundary, within the Cal Water Property (Southern Greenhouse Parcel). The proposed Project is surrounded by residential development in all directions. Several geological soil testing investigations within portions of the proposed Project APE indicated that Colma Creek or related meandering water courses deposited substantial layers of alluvial sediment including sands, gravel and silts during periods of excessive rainfall and subsequent runoff. These are summarized below. A Site Assessment was conducted in the Cal Water Property (Southern Greenhouse Parcel) just west of the Park boundary (CSS 2012). The assessment determined that up to 2 feet of fill had been placed on top of intact, native soils. The imported fill was generally described as dark brown, brown, or strong brown sand with varying amounts of silt, clay, and gravel. The intact, native soil underlying the fill consisted of yellowish brown to dark yellowish-brown fine sand with a trace of silt, identified as alluvial sediments deposited by Colma Creek or a related water course. This intact, native soil extended to 20 feet below surface, “interrupted only by a 3- to 6-inch lens of reddish brown medium sand below 10 feet and occasional deeper, thin (2- to 6-inch) clay lenses interbedded with the yellowish brown sand.” A Preliminary Geotechnical Feasibility Study was conducted in the Cal Water Property (Southern Greenhouse Parcel) for the proposed Project (Fugro 2016). Three borings generally encountered fill overlying native poorly- graded sands with alluvial clay and silty sand with clay over clay with sand. Boring B-1 encountered approximately 2 feet of fill (poorly-graded sand with gravel and clay) overlying approximately 18 feet of poorly-graded sands and silt sands. Boring B-2 encountered approximately 1 foot of fill (poorly-graded sand with gravel and silt) overlying approximately 17.5 feet of poorly-graded sands with silt. Boring B-3 encountered approximately 2.5 feet of fill EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 6 (poorly-graded sand with gravel and silt) overlying approximately 17.5 feet of poorly-graded sand with silt. The soils again are a result of creek or related drainage deposition. A Geotechnical Investigation conducted for the proposed Project (Cotton, Shires, and Associates, Inc. 2018) included borings within the baseball fields in the southern portion of the Park. Four soil borings, B-4, B-5, B-6, and B-7, were completed in the proposed Project APE within the baseball fields. The borings indicated, generally, a 4.5- to 5-foot thick layer of clayey fill overlying alluvial sands, and silty or clayey sands within the baseball fields. Soil boring B-4 was located in the northern corner of the baseball fields and encountered dark brown sandy clay fill soil from the ground surface to 4.5 feet below surface and alluvium composed of silty sand, clay, sandy clay, and clayey sand from 4.5 to 46.5 feet below surface. Soil boring B-5 was located in the eastern corner of the ballfields and encountered dark brown silty clay fill soil from the ground surface to 4.5 feet below surface and alluvium composed of layers of sand, silty sand, sandy silty clay, and clayey sand from 4.5 to 31.5 feet below surface. Soil boring B-6 was located in the western corner of the ballfields and encountered dark brown sandy clay fill soil from the ground surface to 4.5 feet below surface and alluvium composed of layers of sand, silty sand, and clayey sand from 4.5 to 33.5 feet below surface. Soil boring B-7 was located in the southern corner of the ballfields and encountered brown sandy silt clay fill soil from the ground surface to 5.0 feet below surface and alluvium composed of sand, silty sand, clay, and clayey sand from 5.0 to 38.5 feet below surface. These investigations are internally consistent in describing a broad area of active alluvial deposition throughout the proposed Project APE over the past several millennia. They illustrate the presence of repeated flooding resulting in dynamic silts, sands, and cobble layered stratigraphy. Vegetation in this type of floodway would be ephemeral and not generally support long-lasting riparian species such as oaks, sycamores and understory shrubs. The environmental context of the proposed Project APE would have encouraged specific resource procurement such as hunting, fishing, or vegetation collection. 3.2 Ethnography At the time of the initial European contact with the Native Americans of the San Francisco Bay area, the Costanoans (from the Spanish costaños, or “coast people”), members of the Penutian linguistic family, inhabited the area from the Carquinez Strait and the northern tip of the San Francisco Peninsula to the region south of Monterey Bay and east to the Diablo Range (Levy 1978). The Costanoans, who called themselves Ohlone, entered the Bay Area from the Delta region approximately 1,500 years ago and displaced earlier Hokan speakers. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 7 Ohlone social organization was based on the tribelet, which consisted of one to five villages and numerous smaller, temporary settlements within a recognized territory (Levy 1978, Milliken 1995, Moratto 1984). Larger tribelets usually had several permanent villages, frequently within close proximity to one another. Tribelet leadership was focused on a chief who attained the position through patrilineal inheritance and a council of elders who served as advisors (Harrington 1933). Territorial boundaries of tribelets were defined by physiographic features. The Ohlone exploited the San Francisco Bay area’s diverse ecology throughout the seasons. At various seasons, parties were sent out from the villages to temporary camps at scattered locations in the tribelet territory to hunt, fish, and gather plant foods (Levy 1978). A large variety of terrestrial animals such as deer, antelope, and elk were hunted using a sinew-backed bow and arrows tipped with stone or bone points. Waterfowl were the most important birds in their diet. Nets were used to capture ducks, quail, rabbits, and small schooling fish (Levy 1978). Tule balsas, used to cross San Francisco Bay and travel through the marshes and streams surrounding the Bay, were also utilized in hunting waterfowl. Acorns were mostly likely an important plant resource along with other nut and seed crops. The most common type of dwelling was a domed structure with a bent-pole frame that was thatched with tule, grass, wild alfalfa, or ferns (Levy 1978). Sweathouses were substantial semi-subterranean structures with timbered sides located within the permanent villages. The Portolá expedition was impressed by a large assembly house on Gazos Creek that was a domed structure large enough to accommodate all 200 inhabitants of the Ohlone village (Crespí 1927). Assembly houses were located in the center of the village with dwellings around them. 3.3 Prehistory Archaeological remains related to the prehistoric occupation of the San Francisco Bay area are evidenced by shellmounds that lined the shores of the Bay. Prehistoric adaptations of the Bay area (Fredrickson 1974, Moratto 1984) are summarized below. Paleo-Indian Period (10,000 to 6,000 B.C.) The earliest well-documented entry and spread of humans in California occurred at the beginning of the Paleo- Indian Period. Social units were small and highly mobile. Known sites have been identified in the contexts of EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 8 ancient lake shores and coastlines evidenced by fluted projectile points and chipped stone crescent hunting implements. Lower Archaic Period (6,000 to 3,000 B.C.) Few archaeological sites have been found in the Bay Area that date to the Lower Archaic Period. The lack of sites may be because of high sedimentation rates of adjacent water courses, leaving sites deeply buried and inaccessible (Fredrickson 1974, Moratto 1984). Middle Archaic Period (3,000 to 500 B.C.) Archaeologists have recovered a great deal of data from sites occupied by the Middle Archaic Period. During the Middle Archaic Period, the broad regional patterns of foraging subsistence strategies were followed by more intensive procurement practices. Subsistence economies were more diversified, possibly including the introduction of acorn processing technology, as well as use of the dart and atlatl for hunting. Populations were growing and occupying more diverse settings. Permanent villages that were occupied throughout the year were established, primarily along major waterways. Upper Archaic Period (500 B.C. to A.D. 700) The onset of status distinctions and other indicators of growing sociopolitical complexity mark the Upper Archaic Period. Exchange systems become more complex and formalized and evidence of regular, sustained trade between groups was seen for the first time. Emergent Period (A.D. 700 to 1800) Several technological and social changes characterized the Emergent Period. The bow and arrow were introduced, replacing the dart and atlatl over time. Territorial boundaries between groups became well-established. Increasing distinctions in an individual’s social status were linked to acquired wealth. Exchange of goods between groups became more regularized with more goods, including raw materials, entering into the exchange networks. Exchange relations became highly regularized and sophisticated in the latter part of this period. The clamshell disk bead became a monetary unit for exchange, and increasing quantities of goods moved greater distances and specialists developed that influenced various aspects of production and exchange. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 9 3.4 History An estimated 7,000 to 10,000 Native Americans lived near San Francisco Bay by the time of European contact in the 18th century (Levy 1978). Spanish explorers were the first Europeans to traverse the San Francisco Peninsula. In 1769 Gaspar de Portola led an expedition that began the Spanish exploration of northern California; however, it was Juan Bautista De Anza who received orders from the Viceroy of Mexico in 1775 to establish a mission in San Francisco. The arrival of the Spanish in northern California led to the rapid demise of the local Native American population. The native way of life was destroyed by disease, declining birth rates, and the establishment of the Mission San Francisco de Asís in 1776. By 1832, the Native American population had been reduced by approximately 80 percent. The surviving Costanoan’s along with neighboring groups, were forced into the missions and turned into agricultural laborers. With the abandonment of the mission system by the Mexicans, ranchos were established and the few remaining Native Americans worked on the ranchos. During the 1830s and 1840s, settlers in search of large expanses of land or trappers in search of fur-bearing animals began to occupy California in large numbers. Tension between the settlers and Native Americans escalated during the Mexican War in 1846, ending with the signing of the Treaty of Guadalupe Hidalgo in 1848. The Gold Rush had a large impact on San Francisco, as the city became the main port, transportation hub, and commercial center for new settlers looking for their fortune. Prior to 1860, the main form of transportation throughout the San Francisco Bay area was by boat or stagecoach. The first roads were constructed in the mid- 19th century and these roads were primarily used to transport agricultural products to market. A maritime transportation network grew up around the economy of the Bay area to facilitate the movement of agricultural products. In 1864, the construction of the San Francisco-San Jose Railroad and the organization of the Southern Pacific Railroad Company created a link between communities. The railroad also spurred the development of new towns. 4.0 SOURCES CONSULTED This section describes the results of the records search conducted at the regional Information Center for the California Historical Resources Information System (CHRIS). It also summarizes correspondence with the Native American Heritage Commission (NAHC) regarding the proposed Project. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 10 4.1 Cultural Resources Records Search An archaeological site record and literature search was conducted at the CHRIS Northwest Information Center (NWIC) at Sonoma State University for the proposed Project APE on November 2, 2018 (Appendix A). Other sources consulted for resources within the APE include the National Register of Historic Places (NRHP), California Register of Historical Resources (CRHR), California Historical Landmarks, California Points of Historical Interest, and California Inventory of Historic Resources. Over 30 investigations have been undertaken within an area extending 0.5-mile from the proposed Project APE. Two of these covered small portions of the proposed Project APE. A cultural resources evaluation, consisting of background research and a surface reconnaissance, was conducted for a sewer replacement project that passed through the Park, along Colma Creek (Chavez 1977). No prehistoric or historic-period resources were observed, and the assessment concluded that the project would have no adverse effects on known cultural resources. Background research and an intensive archaeological reconnaissance were conducted as part of the Orange Memorial Park Master Plan Environmental Impact Report (EIR) (Clark 1992). The Master Plan EIR included areas north of Colma Creek, outside the proposed Project APE, but also the creek channel and the Cal Water Property (Southern Greenhouse Parcel) within the proposed Project APE. The ground surface within Master Plan EIR areas was covered by imported fill soil, asphalt, and/or concrete. No evidence of cultural materials was observed within the proposed Project APE. No cultural resources are recorded within the proposed Project APE. Three resources are documented within 0.5- mile of the proposed Project APE (Table 1). Table 1. Archaeological Resources within 0.5 Mile of Proposed Project APE Primary No. Trinomial Distance / Direction from APE Period of Occupation Site Type P-41-000048 CA-SMA-44 1,750 ft., southeast prehistoric unknown P-41-000409 CA-SMA-299 2,550 ft., northwest prehistoric habitation debris P-41-000495 CA-SMA-355 650 ft., northwest prehistoric habitation debris including hearths/pits EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 11 P-41-000048 (CA-SMA-44) The site is located approximately 535 meters (1,755 feet) southeast of the proposed Project APE. The Archaeological Site Survey Record for the site does not provide any information (no size measurements, no description of archaeological materials, no sketch map). The site was most likely recorded by Nelson in 1909 along with other shell mounds in the San Francisco Bay area (personal communication, Blake Brown, Northwest Information Center). Because the site was recorded over 100 years ago, very little information about the site remains; the site location depicted by the NWIC is considered approximate (personal communication, Blake Brown, Northwest Information Center). P-41-000409 (CA-SMA-299) The site is located approximately 775 meters (2,542 feet) northwest of the proposed Project APE, near the intersection of Colma Creek and the Southern Pacific Railroad tracks. The site was originally documented in 1989 as an approximately 2-kilometer (1.2-mile) long shell midden with traces of shell fragments, fire-altered rock, and chipped stone flakes on the surface. The Archeological Site Record indicates the site was “completely destroyed” with no traces of the site in many areas. An investigation for the BART – San Francisco Airport Extension Project (Rice 1994) identified no evidence of the site on the recorded site ground surface. Additionally, 20 shovel auger tests encountered no subsurface materials. The Archaeological Site Record indicates the site was “completely disturbed.” P-41-000495 (CA-SMA-355) The site is located approximately 200 meters (656 feet) northwest of the proposed Project APE, along the north bank of Colma Creek. It consists of prehistoric habitation debris, including midden soil, burned and fire-cracked rock, charcoal, chert flakes, ground stone fragments, and burned and unburned bone in a roughly 185 X 80-meter (607 X 262-foot) area, and is between 10 and 130 centimeters (4 and 51 inches) thick. The archaeological resource was buried below 1.5 to 7.3 meters (4.9 to 24.0 feet) of natural and artificial overburden and was discovered during auger testing for a proposed building project. The archaeological site record and literature search indicates prehistoric occupation occurred along Colma Creek within 0.5 mile of the proposed Project APE. Understanding of CA-SMA-44 is extremely limited, but CA-SMA-299 and - 355 represent temporary or seasonal campsites within the vicinity of Colma Creek. Both have been buried by alluvial sediments carried by the creek. Although previous soil testing within the proposed Project APE has suggested dynamic EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 12 alluvial sedimentation over time, the potential for in situ (i.e., in the original depositional location) cultural resources within proposed improvement areas exist. 4.2 Native American Consultation A search of the Native American Heritage Commission’s (NAHC’s) Sacred Lands File was requested on October 10, 2018, and conducted on November 5, 2018 (Gayle Totton, NAHC Associate Governmental Program Analyst) to determine the presence of any Native American tribal heritage resources within the APE and general vicinity (Appendix B). The NAHC indicated that Native American tribal heritage sites are not recorded within the proposed Project APE or vicinity. The NAHC identified seven Native American contacts, both tribes and bands, that would potentially have specific knowledge as to whether cultural resources are identified in the APE. The list of contacts is provided below: • Amah Mutsun Tribal Band, Valentin Lopez, Chairperson • Amah Mutsun Tribal Band, Edward Ketchum • Amah Mutsun Tribal Band of Mission San Juan Bautista, Irenne Zwierlein, Chairperson • Costanoan Rumsen Carmel Tribe, Tony Cerda, Chairperson • Indian Canyon Mutsun Band of Costanoan, Ann Marie Sayers, Chairperson • Muwekma Ohlone Indian Tribe of the SF Bay Area, Charlene Nijmeh, Chairperson • The Ohlone Indian Tribe, Andrew Galvan Letters to these Native American contacts were sent on May 7 and 8, 2019. Follow-up phone calls were made on June 28, 2019 and the original letter was sent by electronic mail on July 8, 2019. No response had been received as of July 28, 2019. The Native American consultation results are summarized in Table 2 below. 5.0 FIELD METHODS 5.1 Phase 1 Archaeological Survey A Phase 1 archaeological survey (i.e., an intensive, pedestrian ground surface survey) of the proposed Project APE to assess the presence/absence of cultural resources to identify potential impacts associated with the proposed project was conducted on January 4, 2019.

Installation of the proposed diversion channel and inlet junction structure (trash screen) are located within an undeveloped field. Background research indicated that fill soil up to 2 feet thick was placed within this area (CSS 2012). Ground surfaces within this area were partially covered by annual grasses and eucalyptus leaf litter, providing good to very good (60 to 80 percent) ground surface visibility. A storm drain and construction debris (concrete) were observed within this area, indicating past ground disturbing activities. Exposed soils within this area were comprised of yellowish-brown sandy loam in the northeast corner of the parcel and brown sandy loam in the center of the parcel, consistent with the results of the previous geological Site Assessment (CSS 2012). Picnic Area Proposed ground disturbing activities within the picnic area include the installation of a 24-inch, underground storm drain pipe that will extend east from the inlet junction structure on the Cal Water Property (Southern Greenhouse Parcel) through the existing picnic area, to the baseball fields (see Figure 2). The proposed storm drain pipe will be oriented parallel with Colma Creek. Ground surfaces within this area were partially covered by a playground and grass turf. Evidence of past grading for water drainage is visible in elevation changes around the playground and planted trees. Substantial areas of barren ground surface approximately 1-square meter in size were observed within the grass turf, resulting in very good to complete (70 to 100 percent) ground surface visibility. Evidence of past ground disturbing activities including a storm drain manhole and irrigation control boxes were observed within the proposed Project APE. Soils observed were yellowish brown and brown sandy loam. Additional existing disturbances included the installation of irrigation within the northern half of the picnic area. Ground surfaces within the area are partially covered by grass turf and eucalyptus leaf litter within landscaped areas. Within the areas of grass turf, approximately 1-square meter of ground surface was visible every 2 square meters. In areas of heavy leaf litter, shovel scrapes were performed at 3-meter (9.8-foot) intervals in order to increase ground surface visibility, providing excellent (90 percent) ground surface visibility. Soils observed were comprised of yellowish brown and brown sandy loam. Baseball Fields Proposed ground disturbing activities within the existing baseball fields include the installation of a series of filtration chambers connected to the 24-inch, underground storm drain pipe that flows into underground stormwater storage chambers, a water quality equipment shed with an irrigation pump, new irrigation, and EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 15 regrading of the baseball fields (see Figure 2). There was no ground surface visibility within the majority of the proposed Project APE; ground surface visibility was precluded by healthy grass turf that was in good condition due to recent rainfall and imported dirt used for the baseball infields. Ground surfaces outside of the periphery of the proposed Project APE were also inspected. The ground surface within these areas was covered by wood chips. In order to improve ground surface visibility in areas covered by wood chips, 0.5 X 0.5-meter exposures were completed approximately every 3 meters (9.8 feet), providing excellent (90 percent) ground surface visibility. The ground surface along the western edge of the proposed Project APE within the area of the proposed water quality equipment shed and irrigation pump was partially covered by spotty grass turf, resulting in excellent (80 to 90 percent) ground surface visibility. Soils observed included redeposited fill soil consisting of brown, light brown, and yellowish-brown clayey sand and sandy loam. Small yellowish-brown clay nodules were observed within the fill soil. These results are consistent with the previous Geotechnical Investigation (Cotton, Shires, and Associates, Inc. 2018). 5.2 Extended Phase 1 Archaeological Excavation An Extended Phase 1 Archaeological Excavation was conducted to evaluate the potential for buried prehistoric archaeological materials for the following reasons: the presence of fill soil that has been placed in proposed Project improvement areas within the Park; potential alluvial deposition as identified in previous soil investigations, and; the presence of at least two prehistoric campsites sites within 0.5-mile of the proposed Project area. Methods Fourteen (14) solid core geoprobes, 2-inches in diameter, were excavated throughout the proposed Project APE to recover continuous soil cores up to 12-feet deep, the maximum depth of proposed Project disturbance. The geoprobes were spaced between approximately 30 and 60 meters (98.5 and 197 feet) apart (see Figure 3). Excavated soils were inspected by Ken Victorino, RPA, Wood E&IS Senior Archaeologist, and Lucas Nichols, Wood E&IS Staff Archaeologist, for the presence of prehistoric archaeological material. Screening of soils was anticipated in the event that any cultural resources were observed. Results of geoprobe excavations were documented on forms; provenience information, sediment description, and termination depth were noted (Appendix C). After excavation of a geoprobe was completed, the geoprobe hole was backfilled. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT 16 Results The Extended Phase 1 Archaeological Excavation results are summarized in Table 3 below. Fill soil overlies intact, native soils. This soil profile/stratigraphy is consistent with previous geotechnical investigations conducted for the proposed Project. The intact, native soils represent multiple “fining upward” sequences associated with repeated flooding along Colma Creek, or suggest that the Colma Creek channel meandered and changed locations. A single “fining upward” sequence consists of large course sand at the bottom, then medium and fine sand, and fine clay sediment at the top. The heavier, large course sand is deposited first, at the beginning, when the water is flowing quickly, and the lighter, fine clay sediments are deposited last, at the end, when the water flow has decreased, and the water is calm and flowing slowly. These multiple “fining upward” sequences suggest that a stable ground surface, that was exposed for a long period of time and was suitable for prehistoric occupation, was not present within the proposed Project APE. No cultural materials were observed in any of the geoprobe cores such that soil screening was not necessary. 6.0 STUDY FINDINGS AND CONCLUSIONS As described above, proposed Project improvements will extend into intact, top soils underlying fill soil. The excavation of 14 geoprobes encountered intact, undisturbed alluvial soil consisting of multiple “fining upward” sequences. This soil profile/stratigraphy is consistent with previous geotechnical investigations conducted for the proposed Project. These intact subsoils associated with repeated flooding along Colma Creek or a meandering channel that changed location have a very low potential for the presence of prehistoric archaeological sites, as a ground surface would not have been exposed long enough to develop into a stable surface suitable for prehistoric occupation. Evidence of ephemeral prehistoric occupation associated with special use activities such as hunting, fishing, or vegetation gathering would have been eroded and carried downstream. The Extended Phase 1 Archaeological Excavation did not recovery prehistoric or historic-period archaeological materials from any of the soil recovered during the excavation of 14 geoprobes, confirming the proposed Project APE has a low potential for the presence of prehistoric archaeological sites. No further archaeological measures, including monitoring during proposed Project construction, are recommended. EXTENDED PHASE 1 ARCHAEOLOGICAL EXCAVATION REPORT Table 3.

Please note that the absence of specific site information in the Sacred Lands File does not indicate the absence of Native American cultural resources in any APE. Attached is a list of tribes culturally affiliated to the project area. I suggest you contact all of the listed Tribes. If they cannot supply information, they might recommend others with specific knowledge. The list should provide a starting place to locate areas of potential adverse impact within the APE. By contacting all those on the list, your organization will be better able to respond to claims of failure to consult. If a response has not been received within two weeks of notification, the NAHC requests that you follow-up with a telephone call to ensure that the project information has been received. If you receive notification of change of addresses and phone numbers from any of these individuals or groups, please notify me. With your assistance we are able to assure that our lists contain current information. If you have any questions or need additional information, please contact via email: [email protected].

Box 5272 Galt, CA 95632 Dear Chairperson Lopez: The City of South San Francisco proposes to construct the Water Capture Project (Project), in Orange Memorial Park (Park), South San Francisco, California (see Enclosure 1, Figure 1). The proposed Project will provide water quality improvements to meet the National Pollutant Discharge and Elimination System requirements of the San Francisco Bay Municipal Regional Stormwater Permit (MRP), which governs stormwater discharges to San Francisco Bay from the City of South San Francisco and 21 other co-permittees in San Mateo County. The proposed Project is designed to address multiple water quality targets outlined in the MRP as well as solid waste (trash) discharge reductions under the MRP requirements. The proposed Project involves the installation of a drop inlet, diversion channel, and inlet junction structure (trash screen) in the upper and western end of the Colma Creek channel and Park boundary and a series of storm pipes · and pretreatment chambers that lead to an underground stormwater storage reservoir in the southeastern comer of the Park underneath a portion of two baseball fields (see Enclosure 1, Figure 2). A portion of the underground stormwater storage reservoir will function as a cistern holding water for future non-potable irrigation and the remainder will function as an infiltration chamber. The proposed Project Area of Potential Effect (APE) includes the horizontal and vertical extent of all temporary and permanent topographic modifications (see Enclosure 1, Figure 3). Ground disturbances associated with the proposed Project will extend at least 10 to 12 feet below the existing ground surface. Based on the results of prior geological soil testing investigations within portions of the proposed Project APE, Colma Creek or related meandering water courses deposited layers of alluvial sediment including sands, gravels, and silts during periods of excessive rainfall and subsequent runoff. A search of the Native American Heritage Commission's (NAHC's) Sacred Lands File (SLF) was requested on October 10, 2018 to determine the presence of any Native American heritage resources within the proposed Project APE (see Enclosure 2).

A portion of the underground stormwater storage reservoir will function as a cistern holding water for future non-potable irrigation and the remainder will function as an infiltration chamber. The proposed Project Area of Potential Effect (APE) includes the horizontal and vertical extent of all temporary and permanent topographic modifications (see Enclosure 1, Figure 3). Ground disturbances associated with the proposed Project will extend at least IO to 12 feet below the existing ground surface. Based on the results of prior geological soil testing investigations within portions of the proposed Project APE, Colma Creek or related meandering water courses deposited layers of alluvial sediment including sands, gravels, and silts during periods of excessive rainfall and subsequent runoff. A search of the Native American Heritage Commission's (NAHC's) Sacred Lands File (SLF) was requested on October 10, 2018 to determine the presence of any Native American heritage resources within the proposed Project APE (see Enclosure 2).
