Staff reports from the California Coastal Commission are long, dry and full of permit numbers. They are also the best public record of how bluff protection in Solana Beach actually gets built, patched and rebuilt over time. In June 2026 the Commission’s staff published a report on a repair at a bluff-top condominium complex in the city. Read end to end, it shows how a lower seawall and upper-bluff supports pile up into one system over half a century.
We are not naming the property; the point is the pattern, not the address. Here is the briefing.
Briefing in brief
- Protection on a Solana Beach bluff is rarely one structure. It is a stack of works added decade by decade: a seawall at the toe, walls and crib walls on the face, and drilled piers or caissons under the building at the top.
- Repairs are tracked as a percentage of the original structure. Crossing 50 percent, cumulatively, changes how the Commission treats the whole thing.
- Accurate as-built plans are now a permit condition, because they are how the next percentage gets calculated.
- Whether a building counts as “existing” for shoreline protection purposes is a legal question tied to January 1, 1977. It is not something a contractor or engineer decides.
Two layers, two jobs
Solana Beach bluffs are generally described as harder sandstone at the base with looser terrace deposits above. The City’s certified Land Use Plan, quoted in the report, adds a detail that matters here: a “clean sand lens” at the base of the terrace deposits. Once that lens is exposed, the plan says, a taller tied-back seawall, around 35 feet high, may be needed to cover and encapsulate it. If that is done at the right stage, the plan says, the wall can minimize or prevent the need for future mid- or upper-bluff stabilization.
In other words, the lower wall and the upper supports are not interchangeable. The seawall resists the ocean at the toe. The upper piers and caissons hold the building up if the softer material near the top retreats. Each covers a different failure.
One bluff, five decades
The report’s project history reads like a timeline of local bluff engineering. Paraphrased:
- Early 1970s. The condominium complex is built, before the Coastal Act took effect.
- 1977. The Commission approves a seawall of roughly 540 feet at the base of the bluff. It is built around 1978, with crib walls added on the bluff face and later extended.
- 1983. After sand loss undermines the wall, the Commission approves deeper footings and backfill.
- 1989. A mid-bluff retaining wall and twenty-nine drilled piers, roughly 52 feet deep, go in to underpin one corner of the building.
- 2001. Five larger buried piers, 36 inches in diameter and roughly 28 to 70 feet deep, are approved below the same corner, along with a sand-supply mitigation obligation running through 2031.
- 2002 and 2007. Colored, sculpted concrete infill is approved around exposed piers at the top of the bluff, plus temporary shoring for the workers installing it.
- 2026. The current repair.
Each step answered a specific problem at a specific time. Together they make a system that no single drawing describes.
What the 2026 repair covers
The application covers the southern 170 feet of the 540-foot seawall: new tiebacks, a shotcrete surface about three inches of which is colored and sculpted to blend with the bluff, repair at an upper-bluff concrete pier using shotcrete infill, and fixes to the private beach stair, including two support piers.
The report describes the existing wall as about 17 feet tall from the bottom of its buried footing, tied back into the bluff. The new face would sit about seven inches farther seaward, but not past the edge of the existing footing, which is roughly 7.5 feet wide.
Why does a repair need a permit at all? The report points to section 13252 of the Commission’s regulations, which requires a permit for repair and maintenance involving mechanized equipment within 20 feet of coastal waters. On a beach-level seawall, that is almost always the case.
The number that matters: 31 percent
The report calculates the repair at 31 percent of the seawall, 170 of 540 feet. That figure is under the 50 percent mark the Land Use Plan uses for redevelopment, so the work is treated as repair and augmentation of an existing structure rather than a new one.
But the count does not reset. The report says that when cumulative alterations reach 50 percent or more of the seawall, or significant changes to its foundation are needed, the seawall will be analyzed as a new structure. That is why the permit requires as-built plans within 30 days of completion, tied to a standard elevation datum and backed by photographs. The next repair will be measured against this one.
The plan’s redevelopment definition works the same way for bluff-top buildings: alterations to major structural components, such as walls, floors, roof structure and foundation, are counted cumulatively over time.
The 1977 line
The report notes the condos were built before the Coastal Act and are therefore treated as an existing structure under Public Resources Code section 30235, the section that allows shoreline protection for existing structures in danger from erosion. A 2024 appellate decision in the Casa Mira case was reported to uphold the Commission’s reading that “existing” means in place before January 1, 1977. Many Solana Beach buildings date from the 1970s, close to that line. If the question applies to your property, it belongs with counsel and the Commission. We do not give opinions on eligibility.
What owners and boards can take from this
- Keep every as-built. Plans, photos and closeout reports from past work are how future percentages get calculated. Missing records make every later project harder.
- Track the cumulative count yourself. A simple table of each repair, its length or extent, its permit number and date saves real confusion later.
- Evaluate the system, not one piece. A sound seawall below aging upper piers, or the reverse, is still a weak system.
- Plan for review. Repairs at the toe usually involve Commission review. Timing depends on the agencies and the application, and no one can promise an outcome or a date.
- Read the conditions. Permits often carry monitoring, maintenance and appearance requirements that outlast the project.
Where we fit
We work on the building and the structures that support it, to engineered plans and approved permits. That includes seawall facing, tieback and caisson repair, drainage, and closeout documentation. Design and stability judgments belong to your engineers and engineering geologist, and we coordinate with licensed engineers as needed throughout.
