ACI rebuilds eroded retention pond and lake banks with regrading, rip rap, coir logs and the PondTech plank system, priced by the linear foot.

Venice is full of man made water. Chestnut Creek alone covers over 250 acres with 20 lakes inside it, the Venice Golf and Country Club has 26 more, Venice Gardens was laid out around a chain of interior lakes and canals, and almost every community built since has a stormwater pond behind somebody's back fence. Those banks were graded once when the place was built and then handed to a mowing crew. Over the years the water works the toe of the slope, the sand behind it washes out, and one morning a board member sends round a photo of a sod mat hanging over open water with nothing underneath it.
We repair lake banks and shorelines in Venice for $50 to $100 per linear foot, depending on how far the bank has gone and how hard it is to get equipment to it. There is more than one way to fix it and we will walk you through all of them. Regrading back to the original 4:1 slope, rip rap rock embankment, coconut fiber coir logs set against the shoreline for a natural edge, or the PondTech plank system, a proprietary product licensed, installed and only available through our company. On the older Venice Gardens lakes and the Chestnut Creek ponds we walk the whole perimeter with the board before quoting, because the sections about to fail are rarely the ones people are already looking at.
Three things do most of the damage here. The soil is sand, so once water gets behind the sod there is nothing holding the slope together. Water levels swing hard between the dry season and the summer rain, which works the same band of bank up and down all year. And mowers scalp the top of the slope, which kills the root mass that was doing the holding.
Once a bank is undercut it does not stop on its own. It takes the sod, then the irrigation line, then whatever is behind it. The cheapest version of this job is always the one done before a homeowner's fence post is hanging in the air.
A stormwater pond is built with a gentle slope for a reason. That slope holds sod, slows runoff before it reaches the water, and keeps the edge stable. Once the bank starts to cut back the slope steepens, the sod loses its footing, and the pond fills with the material it lost.
The damage rarely stops at the waterline. Catch it early and the repair is a fraction of what it costs after the edge has moved.
There is no single right fix. It depends on how much bank is gone, how much wave action the pond takes, what the water level does through the year, and what the association has to spend. Here is what we install.
This is usually the first question a board asks and it is a fair one. A common repair around here is a sock tube filled with sand laid along the shoreline. Those tubes can split and lose their sand in five to seven years, and then the association pays for the same stretch of bank twice.
We would rather tell you up front what each option gives you. Rock does not rot. Coir is organic and is meant to hold the bank while plants take root and take over. The plank system exists because customers were tired of the repair coming back around as a line item every few years.
We price by the linear foot so the number is easy to put in front of a board. We walk the site with you or with your manager, mark what needs attention now and what can wait a season, and put it in writing. Nobody has to guess what they are voting on.
Crews arrive in uniform in clean lettered trucks, work around residents and cart traffic, and clean up at the end of the day. We carry workers compensation and general liability insurance and can send certificates before we mobilize.
Plenty of contractors bidding your pond install one thing, usually a sand filled sock tube, because it is the only thing they carry. We carry several systems and we take the time to explain each one, what it costs, and how long it should hold. Boards often find that a different approach fits the budget better than the traditional method.
We also install the PondTech plank system, which is a proprietary product licensed, installed and only available through our company. The planks go in subsurface and help move water to the pond without it causing surface erosion. It came out of watching customers react to the same erosion over and over. They wanted something that helps keep it from starting again, so we went and found it.

It depends on what goes in. A sand filled sock tube, which is a common install around here, can split and lose its sand in five to seven years. Rock and the PondTech plank system are built to hold up better than that. We will tell you what to expect from each option before you pick one.
Lake bank work generally runs $50 to $100 per linear foot depending on the treatment, the access, and how much fill the bank needs. We measure the run and give you a written estimate at no charge.
That is why we started installing the PondTech plank system. Regrading and rock repair the damage that is already there. The plank system goes in along the bank to help head off the next round of it. The customers who ask for it are usually tired of reacting every few years and want something proactive.
Yes. A large portion of our work is repeat business with the same communities year after year. We are used to board meetings, budget cycles, and scheduling around residents and play.
We size the equipment to the site and stay off what we do not need to touch. Anything we disturb gets put back, and the crew cleans up before it leaves. Residents will see uniformed people and lettered trucks, so there is no question who is out there.
Sometimes, depending on the water body and the scope of the repair. We will walk the site, tell you what we think applies, and point you in the right direction before anything gets scheduled.
Between $50 and $100 per linear foot. Where you land in that range depends on how badly the bank has gone, whether the fix is a regrade, rock, coir logs or a plank system, and how easily we can get equipment down to the water. We quote the whole perimeter free so a board can budget it properly.
It is a plank system installed subsurface along the bank that holds the soil and helps move water to the pond without it causing surface erosion. It is a proprietary product licensed, installed and only available through our company. It is the proactive option rather than the reactive one, which is the point. On the older Venice pond banks where sod has been failing for years it is usually the fix that actually stays fixed.
Yes, and plenty of Venice communities start that way. We will still walk the full perimeter and tell you what else is close to going, so you can plan the rest rather than being surprised by it next summer.
We work across Sarasota, Charlotte and Manatee Counties, and travel further for storm work.

We clear years of tree growth and sediment out of neglected ditches, swales and canals so stormwater moves the way the system was built to move it.
See Drainage & Canals →
We bring in fill, set the grade and compact it, so your house pad, driveway or parking area sits on ground that drains right and stays put.
