Community lakes are iguana strongholds
The retention and amenity lakes that anchor so many Palm Beach County communities are among the biggest iguana reservoirs in the county. Their graded banks are soft and sunny, they run for hundreds of feet with little foot traffic to disturb the animals, and they're ringed with the maintained turf and plantings iguanas feed on. So the animals den and nest along them in real numbers.
Over time the banks end up honeycombed with burrows. That produces slumping at the waterline, soft spots and small sinkholes in the maintained turf where tunnels have collapsed, and steady erosion that eats back toward walkways, cart paths, and homes.
A recurring bill for the association
For an HOA, this becomes a line item that never goes away — regrading, resodding, and shoring up banks that keep failing. Boards often approve a bank repair, see it hold for a season, and then watch the same stretch slump again because the animals never left.
Why spot-treating doesn't work
The lakes in a community are usually interconnected, whether by culverts, swales, or the animals simply walking between them. That means iguanas move freely across the whole system.
- Clearing one bank draws replacements from adjacent banks and lakes
- Nesting on any bank reseeds the whole community's population
- Erosion and burrow density vary bank to bank but the animals mix freely
- One building's contractor bank repair fails as neighbors' iguanas migrate in
A community-wide program is the fix
Because the animals treat the whole community as one habitat, the durable answer is a community-wide, monitored removal and burrow-collapse program rather than one-off calls at individual buildings. That's what makes the regrading and sod investment actually last instead of failing back into the water each rainy season.
Common questions
Why are HOA lake banks always full of iguanas?
Long, soft, sunny, undisturbed banks beside water give iguanas ideal denning and nesting ground, and the maintained turf and plantings around them provide food, so community lakes accumulate large, established populations over time.
Is bank repair pointless if the iguanas stay?
Largely, yes — repaired banks simply get re-burrowed and slump again. A community-wide removal and burrow-collapse program is what makes the regrading and sod investment last instead of failing repeatedly.
Why can't we just treat the worst bank?
Because the lakes and banks connect and the animals move freely, clearing one stretch draws replacements from the rest of the community. Reducing the whole population is what keeps any single bank from being recolonized.
