Lake bank erosion repair in Palm Beach County

Shoreline Erosion Control rebuilds eroding lake banks for HOAs, condominium associations, golf communities and institutions in Palm Beach County. We are based in Boca Raton, we do every foot of the work ourselves, and we rebuild the slope from the waterline up so the grass roots into the bank and holds. If the grass on your lake stops short of the water, or the edge has turned into a small cliff, that is the problem we fix.

Why do lake banks fail in Palm Beach County?

Most HOA communities in Palm Beach County were built around man made lakes, and many of those lakes were dug to supply fill for the homes. The banks were graded and sodded once, when the community was built. In most communities nobody has touched them since.

Palm Beach County banks fail for the same few reasons. The soil is sand with little to hold it together. The wet season runs May through October, and the afternoon storms send roof and lawn runoff straight down the slope. The water level rises and falls between seasons, so the same strip of bank gets soaked and dried every year. Once the grass at the waterline dies back, nothing holds the soil, and the bank cuts back toward fences and patios. Our guide on why lake banks erode covers each cause.

What rules apply to lakes in Palm Beach County?

Palm Beach County lakes usually answer to 2 sets of rules: the South Florida Water Management District permit for the stormwater system, and the county's own lake rules. Before we write a scope, we check both and confirm who owns the bank, so the board is not paying to fix something that belongs to someone else.

The South Florida Water Management District

Most community lakes here are part of a permitted stormwater system. Section 5.3.2(e)(1) of the district's Environmental Resource Permit Applicant's Handbook, Volume II, requires wet detention side slopes no steeper than 4:1 (horizontal to vertical) from the top of bank out to at least 2 feet below the control elevation. Section 5.3.2(e)(2) says slopes built steeper than 3.5:1 are a substantial deviation. Section 5.4 calls for a perimeter maintenance easement at least 20 feet wide at slopes no steeper than 4:1. When a bank erodes, it usually ends up steeper than the slope the permit was written around. Our guide on the lake bank slope rule covers this in detail.

Palm Beach County Environmental Resources Management

In unincorporated Palm Beach County, the Department of Environmental Resources Management (ERM) requires a permit before excavating a lake that is larger than 1 acre or deeper than 6 feet, under Article 4, Chapter B, Section 10 of the county's Unified Land Development Code. ERM states that lake owners, including homeowner associations, property management companies, golf course managers and municipalities, must maintain the lake and its littoral zone in perpetuity. ERM also points to a 20 foot maintenance easement around each lake.

ERM's lake excavation requirements set the standard for planted littoral zones. The planted shelf must be no steeper than 10:1, and that slope must continue 5 feet waterward beyond the planted zone. The shelf must reach 80% coverage within 180 days, with at least 5 species planted about 2 feet apart, and less than 10% exotic or invasive species after the first year. If your community has a littoral shelf, those conditions are part of what the association maintains. Our guide on whether littoral shelves stop erosion explains what a shelf can and cannot do for the bank above it.

State rules on inspection and minor repair

Under Senate Bill 7040, signed June 28, 2024, Florida now requires periodic stormwater inspections reported to the permitting agency, with a qualified inspector requirement effective June 28, 2025. Rule 62-330.051(12)(e) exempts shoreline restoration with native plantings up to 500 linear feet, within 10 feet waterward of the water line.

Where do we work in Palm Beach County?

We work across the county, including Boca Raton, Delray Beach, Boynton Beach, Lake Worth Beach, Lantana, Greenacres, Wellington, Royal Palm Beach, West Palm Beach, Palm Beach Gardens and Jupiter, along with the unincorporated communities west of the turnpike.

We work with HOAs, condominium associations, golf and country club communities, Community Development Districts, and campuses with lakes on their grounds.

What does a free lake bank walk cover?

A free lake bank walk is a visit where we walk every lake with the manager or a board member. We measure and photograph each section of bank, note where the edge has cut back and how close it sits to fences, patios, pool decks and drain pipes, and check what the permits and governing documents say about who maintains the bank.

After the walk, the board gets a written report and a scope it can put out to bid, whether it hires us or not. If the board wants to phase the repair, our guide on budgeting and phasing a lake bank repair walks through how to sort the work across budgets.

To get started, book a free lake bank walk, take the Lake Bank Risk Score, or call (561) 309 9603.

Questions boards ask

Who has to maintain a lake bank in Palm Beach County?

In most communities it is the association or the Community Development District that owns the lake tract. Palm Beach County ERM states that lake owners must maintain the lake and its littoral zone in perpetuity. Your declaration and plat show exactly where the association's responsibility starts and stops.

Does Palm Beach County require a permit to repair an eroded lake bank?

ERM's lake permit applies to excavating new lakes in unincorporated Palm Beach County, so a bank repair is usually reviewed against the existing stormwater permit and state rules instead. Some minor shoreline plantings are exempt under Rule 62-330.051(12)(e). We check your permit conditions and confirm what applies before we write a scope.

Will rebuilding our bank affect our littoral shelf?

It should not, and the repair should protect it. ERM requires a planted shelf no steeper than 10:1 with the slope carried 5 feet beyond the planted zone, and those conditions stay with the association. We plan the bank work so the shelf stays in place and keeps its coverage.

Can we fix the worst banks this year and the rest later?

Yes. Phase the work by lake, starting with the sections closest to fences, patios and pool decks. A written plan in the minutes shows the board acted.
