Sutter Butte Flood Control Agency directs staff to refund bonds; declines new borrowing now

The Sutter Butte Flood Control Agency Board of Directors on Oct. 8, 2025, directed staff to move forward with a refunding of outstanding assessment revenue bonds but declined to add new borrowing now to create cash for future projects.

Seth, the agency’s budget manager, told the board staff had identified a refunding opportunity that could refinance about $43 million to $46 million of outstanding principal and produce net present‑value savings in the range of roughly 1% to 5% depending on market conditions. "On a net present value basis we could save between 1 and 1 to 2 and a half million dollars," Seth said during the presentation. He added that annual debt‑service savings could be on the order of $85,000 to $200,000 depending on the final structure and interest rates.

The discussion centered on two options: (1) refund the existing bonds now to capture immediate savings, or (2) refund now and include additional new money in the sale to build reserves for the Sutter Bypass East Levee project. Seth said the agency’s bond covenant requires assessments at 110% of annual debt service and that assessment authorization and current maturity limits run through October 2045. He also noted the tax‑exempt rules require a reasonable expectation to expend proceeds within 36 months as a factor in structuring any new issuance.

Why this matters: the agency carries roughly $71.13 million in combined outstanding principal after this month’s debt service payment and is preparing major levee projects that could use either pay‑as‑you‑go funding or proceeds from new bonds. Locking in new money now would reduce uncertainty about future interest rates but would also commit the agency to carry interest costs on cash held for several years if a cost‑share partner does not materialize.

Details and board direction Seth told the board current market conditions could make refunding efficient now; the analysis modeled multiple scenarios, including refunding-only and refunding with new money issued now or in 2028–2030. "Either way, we would have about 3½ to 4½ million dollars of more funds available between 2028 and 2030," Seth said, adding that issuing new money today would also save roughly $250,000 in transaction costs versus a future separate issuance.

Agency staff recommended proceeding with a refunding; staff asked for board input on whether to include new money in the issuance. Michael (agency staff) told directors staff viewed a refunding as a "no‑brainer" to capture savings and to return in November with final approval materials if the board gave clear direction.

Director Mano moved to proceed with the refunding only (no new money issued now). A board member seconded the motion and the board indicated unanimous support by voice/thumbs up for the refunding‑only option; staff said it would return in November with parameters and approval materials for the sale.

What the board was told it can and cannot do Staff emphasized that any new bonds would be structured within the term of the agency’s current assessment authorization (through Oct. 2045) and would not extend assessments or levy new taxes on property owners. Seth also explained that if the agency issued additional proceeds today it would need a legally sufficient expectation to spend those proceeds within 36 months under federal tax rules; staff intends to apply available proceeds to an active construction contract (the Tudor flood risk reduction project) to satisfy that requirement, then bank the freed cash for future levee work if the board chose to issue new money.

Next steps Staff will return to the board in November with detailed refunding parameters, an offering document and recommended bond sale timing for board approval. If the board authorizes a sale, staff will work with the agency’s municipal advisor and underwriter to complete the sale within the board‑authorized parameters.

Board discussion highlights and risks Board members raised questions about the sensitivity of savings to interest rate movements and about the return on invested cash if proceeds were banked. Seth told the board he modeled current market rates plus a 40‑basis‑point cushion for issuance costs and insurance and that municipal finance standards generally support refunding when net present‑value savings reach roughly 2% to 3% of refunded par.

The board’s direction was procedural rather than a final financing authorization: directors approved staff moving forward with a refunding transaction only and asked staff to return in November with the formal approval package and recommended sale parameters.
