Most advice about Mello-Roos taxes in California follows the same script: find the bond payoff date, because these things eventually burn off. That advice will steer you wrong in RiverPark. The special tax attached to homes in Oxnard's largest master-planned community isn't paying down a bond that retires on a schedule. It's a non-bonded, perpetual levy with no early payoff option, and in November 2024 it went through something most Mello-Roos districts never face: a direct vote to gut it. The tax survived. Understanding why matters more to your offer or your listing price than the number itself.
The Assumption That Doesn't Hold Here
Community Facilities District No. 5, the formal name for RiverPark's Mello-Roos tax, was established in 2005 to fund park maintenance, sports field upkeep, flood and storm protection, and supplemental police patrols across the development. The City of Oxnard is explicit about the structure on its own special districts page: "RiverPark is a non-bonded district for maintenance and does not expire." No countdown clock. No refinancing that eventually closes it out. As long as RiverPark exists as a community, the tax exists with it.
That distinction caught enough residents off guard that it became a ballot fight. Two RiverPark residents, Aaron Starr and Alicia Percell, filed three citizen initiatives aimed at repealing or shrinking the tax, which qualified for the November 5, 2024 ballot alongside a fourth measure the City Council placed to preserve the status quo. A group calling itself Protect RiverPark organized in response, and the City hired an outside consultant, Russ Branson Consulting, to produce an independent impact analysis before voters went to the polls.
Four Measures, One Outcome
| Measure | What it would have done | Result (Nov. 5, 2024) |
|---|---|---|
| I (City-sponsored) | Continue current CFD No. 5 funding at existing rates, no tax increase | Passed |
| J | Repeal all CFD No. 5 special taxes | Failed |
| K | Cut the maximum tax rate by 50 percent | Failed |
| L | Restrict what CFD funds can be spent on | Failed |
The certified results, tracked by Ballotpedia, show Measure I passing while J, K, and L were all rejected. The independent 9212 report Oxnard commissioned had estimated that Measure K alone would have forced an $1,000,000 budget reduction for fiscal year 2025/2026, a 23 percent cut to CFD spending. Voters chose to keep funding intact rather than take that reduction.
For a buyer evaluating a RiverPark listing in 2026, this is not ancient political trivia. It's the closest thing a Mello-Roos district gets to a stress test, and this one passed with the funding structure unchanged.
What the Number Actually Is
RiverPark's CFD No. 5 doesn't charge every parcel the same flat fee. The city sets a maximum tax by land use class (single-family attached, single-family detached, high-density, and non-residential), and the applied rate can run below that ceiling in a given year. According to the City's own ballot measure materials, the district applied assessments at 64.28 percent of the existing maximum tax for fiscal year 2024/2025, based on a total CFD No. 5 budget of $4,335,290 that year. The applied percentage can shift from one fiscal year to the next, so confirm the current figure against the property's most recent tax bill rather than this snapshot.
Spread across the district's roughly 3,082 homes and 13 commercial businesses, that budget works out to an average of about $1,400 per parcel per year, or roughly $117 a month. That's a citywide average across every land use class, not a number you should plug into a specific offer. Actual amounts vary by property type and phase, and the maximum tax itself is indexed to rise between 2 and 5 percent annually based on the Consumer Price Index. The only reliable figure for a given house is the one printed on that year's Ventura County property tax bill.
One more data point worth knowing before you write an offer: the district's delinquency rate for fiscal year 2022/23 was 1.15 percent, totaling $35,329.78 in unpaid special tax across the entire CFD, according to the CFD No. 5 annual report the city files each year. That's a low failure-to-pay rate for a special tax district, and it's a quiet signal that the assessment is broadly affordable for the households carrying it.
Where It Shows Up in Your Transaction
A Mello-Roos tax is a public obligation recorded against the property, not a private fee like an HOA due. That distinction changes where you'll find it and who's responsible for surfacing it. Before you write or accept an offer on a RiverPark home, three documents matter:
- The current-year Ventura County property tax bill, which will show a Special Tax or CFD line item separate from the standard 1 percent Prop 13 base rate
- The preliminary title report, which should list any recorded Notice of Special Tax against the parcel
- The seller's transfer disclosure statement, since a recorded CFD special tax is a material fact that affects value and must be disclosed
Because the tax rides on the county tax roll rather than a separate association invoice, it's easy for a buyer comparing two RiverPark homes to see similar HOA dues and assume the total carrying cost is the same. It isn't, if the CFD amount differs by land use class or phase. Pull the actual tax bill for each property you're considering rather than relying on an estimate from a listing sheet.
Reading Across Oxnard's Other CFDs
RiverPark isn't the only Oxnard neighborhood with a Mello-Roos tax, and the districts aren't interchangeable. CFD No. 2, covering Westport at Mandalay Bay, was established in 2000 for a different set of public services. CFD No. 1, which funds school facilities inside RiverPark's boundaries, is a bonded district with an expiration date, unlike CFD No. 5's perpetual structure. If you're cross-shopping newer Oxnard developments against RiverPark, don't assume one district's tax behavior tells you how another will age. Ask specifically whether the CFD attached to a given property is bonded and set to retire, or non-bonded and permanent by design.
What This Means If You're Buying or Selling Now
The practical takeaway cuts two ways. For sellers, the November 2024 vote removed a source of real uncertainty that had been circulating in the neighborhood for most of a year, including community conversations the city held at El Rio Middle School to explain the stakes before the election. A buyer doing diligence today can point to a certified outcome rather than an open political question when deciding whether the assessed level of park maintenance and police patrol funding is likely to hold. City Manager Alex Nguyen's comment to residents during that campaign, that everyone in RiverPark should understand they live in what he called a Mello-Roos neighborhood, was blunt, and after the vote it's also settled.
For buyers, the number itself still narrows the pool compared to non-CFD Oxnard neighborhoods. A monthly obligation in the neighborhood of $100 to $150 or more, layered onto principal, interest, insurance, and any HOA dues, is a real line in a lender's debt-to-income calculation. Confirm the exact figure for the specific parcel, factor the CPI escalator into a five- or ten-year hold, and price the total cost of ownership rather than the sticker price on the listing.
A Few Questions Worth Settling Before You Offer
Does the RiverPark Mello-Roos tax ever go away? Not under the current structure. CFD No. 5 is a non-bonded, perpetual district, and the November 2024 vote to reduce or repeal it failed on all three fronts.
Is Mello-Roos the same as HOA dues? No. HOA dues are a private assessment paid to an association. Mello-Roos is a public special tax administered by the city and typically collected on or alongside the county property tax bill.
Will it show up automatically when I get a mortgage quote? Not always. Lenders calculating your payment need the actual CFD figure from the tax bill, not an estimate, so ask your agent to pull it early rather than discovering it during underwriting.
If you're weighing a RiverPark purchase or getting ready to list, the special tax history is one more piece of due diligence worth doing right the first time. Hitchcock & Associates works Oxnard and the surrounding coastal corridor regularly and can pull the current CFD figures, title report, and disclosure documents for a specific property before you write an offer or set a list price.
