SR 07-24-2018 3C City Council Report City Council Meeting: July 24, 2018 Agenda Item: 3.C 1 of 4 To: Mayor and City Council From: Susan Cline, Director, Public Works, Water Resources Subject: Joint Funding Agreement with the U.S. Geological Survey (USGS), for Hydrogeologic Sampling, Planning and Installation of a Deep Nested Monitoring Well, and Development of a Basin-Wide Hydrogeologic Model for the Santa Monica Groundwater Basin Recommended Action Staff recommends that the City Council authorize the City Manager to negotiate and execute a Joint Funding Agreement (JFA) with the U.S. Geological Survey (USGS), an agency within the United States Department of the Interior, for hydrogeologic sampling, planning and installation of a deep nested monitoring well, and development of a basin - wide hydrogeologic model for the Santa Monica Groundwater Basin. This recommendation is made as an exception to the competitive bidding process pursuant to Section 2.24.080 (d) and is for an initial amount not to exceed $1,800,000. Future year funding is contingent on Council budget approval. Summary To help the City achieve its goal of water self-sufficiency, staff recommends that the City enter into a Joint Funding Agreement with the United States Geological Survey (USGS) to install a monitoring well for the City’s Sustainable Water Infrastructure Project (SWIP) in the Santa Monica Basin and to provide hydrogeological modeling services for an initial amount not to exceed $1,800,000. This agreement would allow the City to meet regulatory requirements for aquifer recharge related to the SWIP and would provide vital hydrogeologic information to assist the City in the sustainable management of its groundwater resources. Discussion On September 12, 2017, the City Council authorized the City Manager to accept and execute a funding agreement in the amount of $56,885,903 with the State Water Resources Control Board (State Water Board) Clean Water State Revolvin g Fund 2 of 4 (CWSRF) Program for the SWIP. The SWIP will help the City achieve water self- sufficiency by 2020. The SWIP will increase the City’s water supply by harvesting and advance treating municipal wastewater, brackish groundwater, stormwater, and urban runoff. In order for advanced treated water from the SWIP to be used for aquifer recharge , staff is required to obtain a permit declaring the SWIP as a Groundwater Replenishment Reuse Project (GRRP) from the State Water Board. The State Water Board defines a GRRP as “a project involving the planned use of recycled municipal wastewater that is operated for the purpose of replenishing a groundwater basin… for use as a source of municipal and domestic water supply.” To operate as a GRRP, the SWIP must meet the State’s recycled water regulations. One of these regulatory requirements is response retention time. State Water Board response retention time requires recycled municipal wastewater applied by a GRRP to be retained underground for a period of approximately two to four months to ensure protection of public health. Staff proposes to work jointly with the United States Geological Survey (USGS) to provide existing City well field modeling information to the USGS and oversee the installation of a minimum of one deep nested (multiple zone) monitoring well to gather critical hydrogeologic data that would be used to prepare a detailed hydrogeologic model of the Santa Monica Groundwater Basin. Additionally, the data would assist the City with studies related to the Sustainable Groundwater Management Act (SGMA). The proposed location for the well is in a median on Olympic Boulevard between Stewart Street and Cloverfield Boulevard. Staff anticipates that well drilling work would commence in late fall 2018 and would be completed by early 2019. Data collection and monitoring work would continue until project completion in approximately 2022. In advance of the drilling work, informational notices would be mailed to residents and businesses within a 500-foot radius of a drilling site. Well drilling activities would be conducted during daytime hours. However, test-pumping activities related to aquifer zone testing and constant rate pump testing, will require continuous water flow over 24 hours or longer for reliable data. The well location is in an industrial corridor, bounded by the Metro Expo Line and office space. 3 of 4 Under a joint funding agreement, City staff and the City’s groundwater consultants would work cooperatively with the USGS to extend the existing USGS groundwater flow model for the Los Angeles Basin into the Santa Monica Groundwater Basin. By incorporating the Santa Monica Groundwater Basin into the broader USGS hydrogeologic model, the City would be able to have a well-defined regional understanding of the occurrence, quantity, and quality of groundwater resources in the Santa Monica Groundwater Basin and would be better able to sustainably manage the long-term yield of the City’s groundwater resources. The USGS would invoice the City for drilling, sampling and analysis, hydrogeologic modeling, and other work related to preparing a hydrogeologic model of the Santa Monica Groundwater Basin. It is envisioned that this working relationship would be a multi-year effort and that any future requests for funding would be presented to City Council for approval. Project completion is estimated in 2022. Depending on initial results, additional funding at a similar level of funding may be neces sary in a future fiscal year to address any identified data gaps. Exception to Competitive Bidding Staff recommends USGS to furnish a monitoring well and collect hydrogeologic data as an exception to competitive bidding per Muni Code 2.24.080 (d). The USGS, a federal government agency has extensive experience drilling and installing deep nested monitoring wells and conducting sophisticated hydrogeologic modeling of groundwater resources. d. The USGS possesses the unique ability or capability to meet the particular technical requirements of the solicitation, such as a good or service that is copyrighted, patented or otherwise only available from one license holder. The purchase is economically available from a single source because: the USGS is recognized a s the penultimate expert in hydrogeologic studies in the United States.

Depending on initial results, additional funding may be necessary in a future fiscal year to address any identified data gaps.
