Two Naples Island homes can share a canal, a bridge, and a mailing address and still trade on different terms in 2026. The variable is not square footage or dock length. It is the roughly 20 feet of concrete behind the parcel and whether the City of Long Beach has already replaced it.
For most of the last decade, that distinction lived in a public works binder. It has now migrated into buyer questions, appraisal notes, and the counteroffer stage. If you are preparing to list on Rivo Alto Canal, Naples Canal, or The Colonnade this year, the transaction friction has moved and it helps to know where it went.
The 174-parcel number that reorganizes the island
The seawalls that shape Naples are city infrastructure, not private improvements. Long Beach Public Works has been clear that the seawalls have been the city's responsibility "for almost a century" and, like a sidewalk, are public infrastructure. That framing matters because it dictates who pays for what, and it is also the framing that a well-informed buyer will echo back to you during due diligence.
Here is the granular figure sellers need. There are 1,572 parcels that reside along the seawalls, 174 of which front the unrepaired portions. Roughly one Naples parcel in nine still sits behind a wall that has not been reconstructed since the 1930s rebuild that followed the 1933 earthquake. Buyers reading market coverage now arrive at the first showing knowing which segment they are looking at.
The distinction between a Phase 1 or Phase 2 frontage and an unrepaired frontage is not cosmetic. Sections of the old wall are visibly cracked and give way to a high tide that routinely floods the sidewalks several inches deep.
What Phases 1 and 2 actually delivered
If you can tell a buyer exactly which phase sits behind the home, you shorten a conversation that would otherwise run through inspection and back.
| Phase | Completion | Extent | What was installed |
|---|---|---|---|
| Phase 1 | Grand opening October 31, 2015 | 1,915 linear feet along both sides of Rivo Alto Canal | 18-inch wide steel sheet-piles on the water side of the existing vertical concrete seawalls |
| Phase 2 | Contract awarded to Reyes Construction, Inc. on June 12, 2019 | 2,148 linear feet at The Colonnade, the south side and eastern end of Treasure Island, and the western end of the Naples Peninsula | New steel sheet-pile seawall plus new sidewalks, guardrails, storm drain systems, lighting, and float access platform modifications |
| Remaining phases | Not scheduled | 174 parcels | Unrepaired original wall |
Two of six sections have been replaced. The rest, per the city's engineering language, sits in "fair condition" with the northwest section of Rivo Alto Canal singled out for deterioration and scouring at the base.
Why the remaining work is stalled, and why buyers ask
The stall is not a funding delay in the ordinary sense. It is a coastal-permitting condition. The California Coastal Commission attached a special condition requiring further seawall construction to coincide with development of the Sorrento Trail, a public walkway along the canal at an expected cost of $12 million, and told the city that if the first phase of the Sorrento Trail for public access is not finished, further seawall repairs cannot continue.
Layer the fiscal side on top. The city needs $125 million to finish replacing the 86-year-old barrier. Tidelands Funds, which are fed by the city's dwindling oil revenue, are expected to decline by $301 million over the next decade, including $21 million by the end of the next fiscal year. Long Beach is already tied up with more than $758 million in infrastructure projects ahead of the 2028 L.A. Olympic build-out.
The proposal buyers want you to comment on is that among the options floated to revive the project is having homeowners foot the bill. No assessment has been adopted, and the city has said it is not married to the idea of having residents foot the bill. A buyer who has read the coverage will still ask. Answering with specifics, rather than reassurances, is what earns their confidence at the negotiating table.
The dock permit that catches sellers at escrow
The seawall is one half of a canal-front sale. The dock is the other, and the permitting rules quietly reshape what you can promise a buyer.
- An Annual Seawall Permit is required for every boat moored adjacent to a waterfront property in the Long Beach Marina area.
- The property owner is responsible for processing the permit for vessels moored at his dock regardless of the ownership of the vessels, and is also responsible for cancellation of the same permits.
- The annual fee is per foot per year based on the overall length of the vessel, due and payable January 1 of each year.
- All dock floats in Rivo Alto Canal and Naples Canal must confirm to a six-foot width limit when they are replaced or substantially repaired, and all docks must comply with the size limitation no later than December 31, 2028.
Read those four items together and the seller checklist writes itself. If your dock is non-compliant on width, the buyer inherits the December 2028 deadline. If a tenant's or family member's vessel sits at the dock at closing, the permit responsibility transfers with the deed. The city routes these questions through a single staffer, and the number that vendors and title officers use is Vilma Hernandez at [email protected], or (562) 570-3239. Calling before you list, not after inspection, is the difference between a clean disclosure and a two-week delay.
Reading the March 2026 median past the headline
Naples posted a median sale price of $2.0M in March 2026, roughly 15% under the same month a year earlier on nine closed sales, with days on market falling to 32 from 50. Median price per square foot moved the opposite direction, running about $1,290, up around 29% year over year. A $/sqft up while the median is down almost always signals a mix shift, not a market shift. Smaller homes closed, larger estates paused. The islands are geographically finite, new supply is essentially impossible, and inventory in nine transactions can rearrange the reported median without changing what a well-prepared listing will actually clear.
For a seller, the operative number is not the median. It is what your specific parcel plus your specific seawall segment plus your specific dock configuration produces in front of the small pool of buyers actively watching Naples in any given month.
What this changes about preparing to list
Three practical moves flow from the above.
Pull the phase map before you set price. If your frontage was included in Phase 1 or Phase 2, that is a defensible line item in your marketing. If it was not, price and disclosure should reflect what the buyer will ask, not what you hope they will not.
Time the dock permit renewal to the listing calendar. A January 1 fee cycle and a buyer's request for a current permit letter should not collide with an active escrow.
Get ahead of the assessment question. There is no adopted assessment. There is a live public conversation about one. A seller who can describe the funding picture in the same language the city and the Naples Improvement Association are using signals expertise, and expertise is what closes canal-front deals.
Seller questions we hear most in 2026
If the seawall behind my home is unrepaired, do I have to disclose it? California disclosure standards require sellers to share known material facts affecting value. The city's public reports about the condition of specific segments are exactly that. Work with your agent and escrow officer on the specific form language, and lean toward more information rather than less.
Can a buyer's lender require a seawall report as a condition of financing? Lender overlays vary. What we see more consistently is appraisers asking questions they did not ask in 2019. Having the phase-map answer ready shortens that loop.
Does the December 31, 2028 dock float rule apply to me if my dock is grandfathered? The rule ties compliance to replacement or substantial repair, with a hard 2028 backstop. If your dock is currently compliant, no immediate action. If it is not, the buyer will price in the future work.
Naples rewards sellers who treat the canal as part of the asset rather than the backdrop. The buyers writing offers here in 2026 are already doing that. Meeting them on their own ground is what turns a listed home into a closed one.
