BOLSA KNOLLS, Monterey County — October 29, 2026. Chronic flooding along Santa Rita Creek remains a major infrastructure and financing question for the unincorporated Bolsa Knolls community north of Salinas. In 2026, Monterey County supervisors accepted a drainage study and requested further work on potential repairs, maintenance, project costs and the question of who should pay.
Why does Bolsa Knolls flood repeatedly?
The county identifies sediment moving downstream from an agricultural watershed, obstruction or limited capacity in drainage structures and the complexity of managing a creek that crosses both public and private land. Santa Rita Creek, also called Little Bear Creek, runs south through the community. The county’s June 2 follow-up report cites a history of damaging flooding across multiple years, including 2014, 2017, 2022, 2023 and 2025.
What are officials considering?
Options under discussion include removing accumulated sediment and excess vegetation, upgrading culverts in parts of the neighborhood and building upstream sediment-retention or stormwater-detention basins. The county also examined whether maintenance and capital projects should be supported through an expanded County Service Area, a new special district or another shared governance arrangement.
What did the Board of Supervisors decide?
On March 24, 2026, the board voted to accept the study and told staff to return with better cost estimates, possible immediate actions, and funding and management options. Staff presented a 60-day follow-up on June 2, 2026. These steps document analysis and public discussion; they do not prove that every proposed basin or culvert has been funded, permitted or built.
What does the funding problem mean?
County Service Area No. 9 provides certain drainage and street-related services but has limited revenue. A wider assessment or governance change may trigger legal procedures and property-owner participation. That is why residents should distinguish relatively immediate maintenance from expensive structural fixes. A project with a preliminary cost estimate is not yet a construction contract.
What should households do now?
People in areas with recurring flooding should check updated county flood maps, request their property’s flood-risk information and use official storm alerts during severe weather. A long-range drainage study does not replace a current evacuation warning or a real-time road-closure notice. Property owners considering flood insurance should confirm their coverage terms directly.
