City Council Meeting: June 14, 2022
Agenda Item: 3.D
1 of 5
To: Mayor and City Council
From: Rick Valte, Public Works Director, Public Works, Water Resources Subject: Adoption of Resolution Approving Olympic Restoration and Arcadia Expansion Project Mitigated Negative Declaration Second Addendum Recommended Action
Staff recommends that the City Council:
1. Adopt the attached resolution to approve the second addendum to the Initial Study and Mitigated Negative Declaration for the Olympic Well Field Restoration and Arcadia Water Treatment Plant Expansion Project to relocate groundwater recharge well SM-11i to the City Yards, add a potential second groundwater recharge well at the City Yards, and replace the existing fence at the Arcadia Water Treatment Plant.
2. Authorize the City Manager to negotiate and execute a first modification to Professional Services Agreement #10873 in the amount of $276,301 with GHD Inc. to provide additional owner’s engineer services and construction support services for the Public Works Department. This would result in a five-year amended agreement with a new total amount not to exceed $1,527,401, with future year funding contingent on Council budget approval.
Summary
The Olympic Well Field Restoration and Arcadia Water Treatment Plant Expansion Project (Project), as outlined in the City’s 2018 Sustainable Water Master Plan Update (Components 2 and 3 in the plan), aims to reduce the City’s reliance on imported water supplies and provide a diverse, sustainable local water supply. A second addendum to the Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared by Dudek for the Project to include an alternative location for groundwater recharge well (SM-11i), moving it from the City’s Ishihara Park to the City Yards to minimize any community impacts. The second addendum to the IS/MND also includes a second groundwater recharge well (SM-12i) within the City Yards and replacing the existing fence 2 of 5
surrounding the Arcadia Water Treatment Plant to upgrade site security. Staff recommends that the City Council adopt the resolution to approve the second addendum to the IS/MND for the Project.
To support the Project, the City also awarded a professional services agreement with GHD Inc. in June 2019 to provide Owner’s Engineer services that included engineering oversight, advisory services, and construction phase services. With the construction phase now fully defined for the project, staff recommends executing a first modification to the professional services agreement in the amount of $276,301 for construction oversight, start-up/commissioning, and asset integration support services for a total contract amount not to exceed $1,527,401.
Discussion
Consistent with the California Environmental Quality Act (CEQA) guidelines, staff conducted an environmental evaluation and prepared an IS/MND for the Project. The IS/MND for the Project was adopted by City Council on November 24, 2020 and a first amendment to the IS/MND, to add the Metropolitan Water District of Southern California as a project partner for contributing up to $19.6 million over a 25 year period to the City’s production of local water supplies, was adopted on February 23, 2021. For the purposes of CEQA, the environmental document prepared for the Project includes all associated improvements required to convey, treat, and improve the production efficiency at the Arcadia Water Treatment Plant. The Project as defined by the CEQA document includes the following key components:
1. Olympic Well Field: Equipping four wells and decommissioning one well within the Olympic Sub-basin.
2. Recycled Water Pipeline: The construction of approximately 1,500 linear feet of recycled watermain pipeline to connect the potential new injection well (SM-11i) within Ishihara Park or alternate location if available.
3. Olympic Pipeline: The construction of approximately 6,600 linear feet of transmission mainline to carry groundwater pumped from the Olympic Subbasin 3 of 5
in the City of Santa Monica to the Arcadia Water Treatment Plant in the City of Los Angeles.
4. Olympic Advanced Water Treatment Facility: The construction of the new well head treatment facility, which would remove 1,4-Dioxane, 1,2,3-TCP, TCE, and PCE contamination from the Olympic Well Field groundwater.
5. Arcadia Water Treatment Plant Expansion: To accommodate the additional volume of groundwater from the Olympic Well Field, the treatment capacity of the plant would be expanded and production efficiency increased.
The second amendment to the IS/MND was prepared in accordance with Section 15164(b) of the State CEQA Guidelines where an addendum to a previously adopted MND is the appropriate environmental document in instances when project changes and additions are necessary, but there would be no new or substantially more significant environmental effects beyond those identified in the MND. Staff has determined that an addendum pursuant to Section 15164 of the CEQA Guidelines is appropriate to address the changes to the approved project. The proposed changes to the IS/MND in the second addendum include the following:
1. Olympic Well Field. Of the four wells being equipped, groundwater recharge well SM-11i located at the Ishihara Park in the original approved project would be relocated to a location outside the park and approximately 0.25 miles west to within the City Yards property. A potential fifth well in the Olympic Well Field used for groundwater recharge, groundwater recharge well SM-12i, would be located within the City Yards property as well.
2. Arcadia Water Treatment Plant Expansion. The existing perimeter fence surrounding the plant would be replaced to enhance site security.
Additional details of the Second Amendment of the IS/MND can be found in the attachments.
