Introduction Environmental Science Associates (ESA) has been retained by the Orange County Water District (OCWD) to prepare a Cultural Resources Study for the proposed Groundwater Replenishment System (GWRS) Final Expansion Project and the Water Production Enhancement Project (referred below as the project) located in the cities of Huntington Beach and Fountain Valley, California. The GWRS is an existing advanced water treatment facility constructed by the OCWD and the Orange County Sanitation District (OCSD) that supplements local water supplies by providing reliable, high-quality source of treated water to recharge the Orange County Groundwater Basin, and to protect the Orange County Groundwater Basin from seawater intrusion. The project would provide facilities that would allow an increase in the amount of water to be conveyed to the GWRS and further supplement the local water supplies. The GWRS Final Expansion Project involves eight components: (1) increasing microfiltration (MF) capacity; (2) increasing reverse osmosis (RO) treatment capacity; (3) increasing ultraviolet (UV) treatment capacity; (4) increasing final product water capacity; (5) construction of an effluent pump station: (6) conversion of existing gravity pipeline to a pressurized pipeline; and (7) construction of a separate headworks and bypass pipeline. The Water Production Enhancement Project involves the proposed flow equalization tank with a pump station, and conveyance piping and flow meter vault. The project is eligible for funding from the State Revolving Fund (SRF) Loan Program, which is administered by the California State Water Resources Control Board (SWRCB). Since the SRF Loan Program is partially funded by the U.S. Environmental Protection Agency (EPA), it is subject to federal environmental regulations including Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended. This Phase I cultural resources study has been prepared in support of the environmental documentation being prepared for the GWRS Final Expansion Project and the environmental documentation being prepared for the Water Production Enhancement Project in compliance with CEQA and Section 106 of the NHPA. The OCWD is the lead agency responsible for compliance with CEQA. ESA personnel involved in the preparation of this study include: Candace Ehringer, M.A., R.P.A., Principal Investigator; Arabesque Said-Abdelwahed, MPP, report author and surveyor; Vanessa Ortiz, M.A., R.P.A, literature review analyst. Resumes of key personnel are provided in Appendix A.

Phase I Cultural Resources Study 1. Introduction 1.1 Project Location The project is located within the cities of Fountain Valley and Huntington Beach (Figure 1). A portion of the project is located at the existing OCWD GWRS Facility in Fountain Valley. The project is also located at the southern portion of OCSD Treatment Plant No. 1 and OCSD Treatment Plant No. 2 in Huntington Beach. In addition, the project includes the renovation of an existing waste water pipeline located along the west side of the Santa Ana River that extends from Treatment Plant No. 2 to the OCWD GWRS Facility. The project is located within section 32 of Township 5 South/Range 10 West and it is located in sections 5, 17, 20, of Township 6 South/Range 10 West as shown on the Newport Beach, California 7.5-minute U.S. Geological Survey topographic map (Figure 2). 1.2 Project Description The project evaluated in this report comprises of two separate projects. The first is the GWRS Final Expansion Project. The second is the Water Production Enhancement Project. The components of each project are illustrated in Figure 3 as well as the potential staging area. 1.2.1 GWRS Final Expansion Project This project includes conversion of an existing gravity pipeline to a pressurized pipeline, increasing MF capacity, increasing RO Treatment Capacity, increasing UV treatment capacity at the OCWD GWRS Facility, final product water and construction of a pump station at the OCSD Plant No. 2. The GWRS takes highly treated wastewater that would have been previously discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process consisting
