BACKGROUND
Since the discovery of invasive Golden Mussel in October 2024 at the Stockton Shipping Canal, the rate of spread has intensified with new adult colonies detected throughout much of the Delta region impacting State Water Project facilities. Watercraft launched in the Delta represents a high risk of Golden Mussel overland transport introduction to inland waters such as Lake Berryessa. Napa County adopted a Mussel Prevention Ordinance in July 2025 authorizing the inspections of watercraft for invasive mussels at Lake Berryessa. Subsequent to enacting the Ordinance a review of boat launch sites around Lake Berryessa determined uninspected watercraft could potentially enter the Property Owner’s Association (POA) lake access point at Berryessa Estates. Solano County Water Agency administers a Launch Seal Program for the Lake Berryessa west side concessionaires and offered a contribution of $40,000 towards the construction of RFID card reader slide gate to regulate entry into the POA recreational area where the unmonitored boat launch resides. Lake Berryessa Resort Improvement District will match the SCWA funds equally with a $40,000 appropriation from its Critical Water Supply Project (22009) fund balance, which will have a remaining fund balance of $2,269,417 after this adjustment. A total budget of $80,000 for construction and contingency is proposed for the Access Road Gate Project. Any residual funds after project completion will be returned to Sustainable Water Supply Project 22009.
Requested Actions:
1. Approve and Authorize revenue Agreement No. 270205B with SCWA for a maximum of $40,000;
2. Approve and authorize the creation of a new capital improvement project for the “LBRID Access Road Gate Installation” (Fund 5220, Sub-Division 5220500, Project 27018); and
3. Approve a Budget Amendment for the following:
a. Increase appropriation for Project 22009 - Sustainable Water Supply in the LBRID Fund (Fund 5220, Sub-Division 5220500) in account 57900 - Intrafund Transfers-Out by $40,000 offset by use of its available fund balance;
b. Increase appropriation in the LBRID-Water budget (Fund 5220, Sub-Division 5220005) in account 57900 - Intrafund Transfers-Out by $40,000 offset by an increase of $40,000 in revenue account 49900 - Intrafund Transfers-In from project 22009; and
c. Increase appropriations for Project 27018 - LBRID Access Road Gate Installation (Fund 5220, Sub-Division 5220500) in account 52360 - Construction Services by $80,000, offset by an increase of $40,000 in revenue account 49900 - Intrafund Transfer-In from the LBRID-Water budget and $40,000 in revenue account 43950 - Other Governmental Agencies from the Solano County Water Agency Launch Seal Program;
