REPORT TO CITY COUNCIL
To:Honorable Mayor and Members of the City Council
From:Jason Simpson, City Manager
Prepared by:Shannon Buckley, Assistant City Manager
Date:August 12, 2025
Subject:On-call Services Agreement with ALV for Lake Water Quality Services Recommendation
Approve and authorize the City Manager to execute an on-call services agreement with ALV for lake water quality services in an amount not to exceed $206,000.00 in such final form approved by the City Attorney and authorize the City Manager to execute change orders not exceeding a 10% contingency of $20,600.00 for uncertainties and adjustments.
Background
On-call contracts provide the City with the ability to quickly and efficiently deploy maintenance and construction services through pre-established terms and conditions. These contracts are especially valuable when urgent needs arise or when the City lacks the internal capacity to perform certain tasks.
For municipalities requiring general or specialized maintenance and construction support, on-call contracts offer several key advantages:
• Access to a broad range of technical expertise
• Flexible and readily available resources
• Service commitments on an as-needed basis
• Streamlined procurement and approval processes
• Objective, third-party evaluations and recommendations • Support for solution-driven actions
In the City of Lake Elsinore, on-call and minor construction service contracts serve as a critical tool to maintain public infrastructure and amenities, while also enabling the efficient and cost- effective delivery of small-scale capital projects.
ALV Agreement for Lake Water Quality Services
Discussion
As part of our ongoing Lake Management Plan, we have been conducting pilot testing of a product called Phoslock, a phosphorus-binding compound designed to reduce excess nutrients in the water. Once applied, Phoslock works by binding with free-floating phosphorus and settling it permanently into the sediment at the bottom of the lake, making it unavailable for biological uptake.
This process plays a critical role in improving water quality and preventing future algal blooms.
Since phosphorus is a primary nutrient that fuels the growth of algae, reducing its availability is a key strategy in curbing the frequency and intensity of harmful algal blooms. The use of Phoslock represents one of several science-based tools we are evaluating to restore ecological balance and enhance the long-term health of Lake Elsinore.
To support the continued implementation of this and other water quality treatment efforts, staff recommends that the City Council approve an on-call contract with ALV. This contract will allow for flexible, timely, and ongoing water quality maintenance and treatment services, including the targeted use of Phoslock and similar best-practice technologies, as needed.
Fiscal Impact
Funds are available in the City’s Fiscal Year 2025-26 Measure Z Budget.
