Who Pays If Rio Vista Buries Its Power Lines After You Buy?

Say you close on a Rio Vista home next year, and two years after that the neighborhood votes to bury its overhead wires. If you bought on the Florida Realtors/Florida Bar AS IS contract, its wording sends the new tax-bill line item to you, not the seller. The final size of that bill also depends on something you can't control: whether every other parcel in the assessment area gets its own connection done within six months of the project's completion.

That's the part of Fort Lauderdale's utility undergrounding program a buyer feels first. It has come up in Rio Vista this month because the Rio Vista Civic Association has scheduled an October 19 general meeting at 7 p.m. at 620 SE 9th Street, with a Zoom option. Rio Vista Online reports that at that meeting Gary Foster of Public Works, who leads the city's undergrounding work, will present it as "an available option in Rio Vista." The city's own undergrounding page lists Rio Vista under "Applications Received," next to Harbor Beach, Harbour Inlet, Seven Isles and Sunrise Key.

No Rio Vista cost estimate, ballot or construction schedule is on the public record yet. A buyer weighing Rio Vista against other waterfront neighborhoods is really asking how this process turns into a bill, and who is holding the deed when it does.

Where your contract puts an assessment that doesn't exist yet

The Florida Realtors/Florida Bar AS IS Residential Contract sorts special assessments into two buckets. The seller pays public-body liens that are certified, confirmed and ratified before closing. The seller also pays the public body's most recent estimate for an improvement that was substantially complete as of the contract's Effective Date but hadn't been liened yet. Then the form says, "Buyer shall pay all other assessments."

An undergrounding project still at the application or ballot stage meets neither seller condition. The commission hasn't adopted an assessment and the wires are still on the poles. On the form's plain wording, that lands in "all other."

The form also covers assessments paid in installments, which is how Fort Lauderdale collects undergrounding costs.

If no one checks a box, the buyer inherits every installment after closing. On a program the city says is repaid over 30 years, that can mean most of the balance.

This is general information about how the standard forms and city process are written, not legal, tax or financial advice. Confirm how any assessment applies to your purchase with your attorney or closing agent.

How a Rio Vista application becomes a tax-bill line

Fort Lauderdale revised Section 25-129 in fall 2025. The changes added a two-phase design process, more upfront fees and an extra ballot. Staff said these came from lessons learned on the program's first project. Rio Vista has finished the first step, the application. Here is the full sequence as the city describes it:

1. The neighborhood association applies, with a fee, a boundary map and notarized meeting minutes.
2. The city checks with FPL and the other utilities and gets ballpark costs.
3. A consultant prepares a conceptual design and preliminary estimates.
4. Ballot #1 goes to every owner inside the boundaries, and at least 70% of returned ballots must approve.
5. The City Commission authorizes design spending and a way to reimburse it, usually a special assessment.
6. Final design is completed and the project goes out to competitive bid.
7. Ballot #2 goes out with final costs, again needing 70% of returned ballots.
8. The commission holds a public hearing and adopts the Final Assessment Resolution.
9. Construction runs, then the poles come down and the area is restored.
10. The assessment shows up on the tax bill of every property inside the boundaries.

The 70% threshold counts returned ballots, with one owner counted per parcel. Owners who don't send a ballot back don't count toward the total. The city doesn't publish a standard timeline from application to construction, and its review of the first project lists the long approval process as a lesson learned. For a buyer, the bucket question from the contract section can stay open across several years of ownership changes.

The one reference project: Las Olas Isles

Only one Fort Lauderdale neighborhood has finished the program. That makes Las Olas Isles the best evidence of how big an assessment gets.

According to the city's July 2, 2024 commission memo, almost 90% of the owners who responded to the ballot supported the assessment. For fiscal year 2025, the city proposed a total assessment of $526,473.68, or $1,709.33 per Equivalent Benefit Unit. That figure was the FY2025 debt service on a 25-year special obligation bond with a $7.9 million par value. The city's 2025 annual report to bondholders names those as the Series 2022 Las Olas Isles Undergrounding bonds, due July 1, 2048, with $7,380,000 still outstanding as of September 30, 2025. The bonds are secured by a lien on the special assessments levied against land in the assessment area. The obligation stays with the parcel, not with whoever owned it when the vote happened.

The Equivalent Benefit Unit is the key to reading any future Rio Vista estimate. The city's methodology spreads costs according to safety, reliability and aesthetic benefit, not market value. In the Las Olas method, a single-family detached parcel counts as one EBU. A smaller house on a quiet Rio Vista street and a larger one on the river could carry the same line item.

Treat the $1,709.33 as an FY2025 Las Olas number. It isn't a current rate and it isn't a Rio Vista forecast. Rio Vista's cost will come from its own design and bids, and its term may also differ. The city's FAQ describes 30-year repayment, while the Las Olas bond was a 25-year issue.

The six-month rule that ties every parcel together

Under the revised ordinance, the second ballot has to show two estimates, one with FPL's 25% contribution-in-aid-of-construction discount and one without it. The ballot also has to tell owners this:

"That one hundred (100) percent of the parcels must be converted to the UULF within six (6) months of completion of the UULF in order for the twenty-five (25) percent discount to apply. That if one hundred (100) percent of the parcels are not converted within this time period, the parcels shall be assessed for the total cost without the twenty-five (25) percent discount"

Converting is partly the owner's job. The ordinance says the estimates leave out several private-side costs. One is hiring a licensed electrician to connect and activate service. Another is bringing the existing meter box up to the Florida Building Code in effect at the time, which may mean replacing wiring from the meter to the connection point. The last is laying conduit from the right-of-way to the meter and repairing the yard afterward, unless the owner agrees in writing to let the city's contractor do that work.

FPL's own conversion FAQ lists a $651.49 FPL fee for an individual overhead-to-underground conversion, on top of electrician, permit, conduit and trenching costs. That page is undated, so check the number against FPL's current tariff.

Taken together, every owner's assessment rises if a single parcel is still unconverted at the six-month mark. That could be a vacant lot, an estate in probate, or an owner who hasn't booked an electrician. When you buy into an undergrounding area, you take on your own conversion timeline, and your bill also depends on everyone else's.

Not the same as FPL's own underground program

You'll see FPL crews burying lines in parts of South Florida under the Storm Secure Underground Program, and the two are easy to confuse. FPL chooses those projects under criteria approved by the Florida Public Service Commission and recovers the cost from all FPL customers through the Storm Protection Plan charge. FPL says voluntary neighborhood conversions are paid for by the community or municipality that opts in. FPL's program covers electric lines. The city program coordinates electric, phone and cable together. A Rio Vista project would be the city kind, paid by the parcels inside its boundaries.

Where Rio Vista sits in the queue

The city's status list shows the order. Las Olas Isles is complete. Idlewyld and Riviera Isles are in design, and Idlewyld's 30% design plans were posted in July 2026. Rio Vista is one of five neighborhoods with applications in. Victoria Park, The Landings and South Gordon Road are listed as having expressed interest. Rio Vista is ahead of the "interest" neighborhoods and behind the two in design. It hasn't reached a first ballot, which means there's no estimate yet for a buyer to price in.

Quick answers

Does an application on file mean Rio Vista will be assessed? No. An assessment needs two ballots, each at 70% of returned ballots, and then a commission public hearing and a Final Assessment Resolution. None of those has happened for Rio Vista.

Will the assessment be based on my home's value? In the Las Olas Isles method, costs were spread by Equivalent Benefit Units, and a single-family detached parcel counted as one unit no matter its market value. Rio Vista's method would be set during its own process.

Can a buyer ask the seller to cover a future assessment? The AS IS form's defaults are summarized above. Anything beyond them is a matter for negotiation and your attorney.
