What's Up with YOUR Lake Banks?
I live in a West Boca community with lots of lakes.
Over the last four years, our community has been engaged in an ongoing dialogue about the gradual erosion of our lake banks and what to do about it. Initially, burrowing catfish were blamed. Then various experts came through to study the matter more thoroughly. A gradual consensus developed that the erosion was mainly caused naturally by wind.
It has been much more difficult to come to a consensus on what to do about lake bank erosion.
A couple of years ago, the Board of Directors appointed a committee of homeowners to study the issue in-depth, assess the extent of the erosion and make recommendations to remedy the problem.
The committee presented a comprehensive report to the Board. They researched five remedial techniques – concrete mat, rip rap, bulkhead, filter fabric, and geo filter tubes. They recommended the geo filter solution because it was both the best aesthetic solution and the cheapest of the five methods. They urged that the geo tube solution be implemented throughout the community in one fell swoop at a cost of about $750,000.
Soon thereafter, Wilma struck and the lake bank project took a back seat to healing the community’s wounds from by far the most damaging hurricane in its 20-year history.
The lake bank issue got back on the front burner in 2007. A new committee was established and made a report to the Board similar to the previous one, but this time it framed the issue with even greater urgency. The Board decided to call for the required homeowner vote on a special assessment to fund a community-wide remedy. The vote will take place at the Association’s 2008 Annual Members Meeting.
About 2/3 of our lake bank linear footage abuts lakefront owner lots and the remaining 1/3 abuts the Common Area. However, the lake banks are 100% owned by the Association. Per HOA counsel, the special assessment must be levied equally on all homeowners, regardless of whether their lots are lakefront or dry.
Both lake bank committees urged the Board to adopt their recommended course of action because a) it would improve the aesthetic quality of our community to the benefit of all b) the continued deterioration of our lake banks increases our community’s liability and c) our Governing Documents obligate the HOA to do so.
Dry lot owners make up 73% of the Association’s membership. Some take the view that the aesthetic result of restoring our lake banks will primarily benefit the 27% of owners who own lakefront lots. It has also been noted that the Documents require the HOA to maintain the lakes, but does not specifically refer to the lake banks. Additionally, the obligation to maintain the lakes is contingent upon the HOA having the funds to do so. If the special assessment is voted down, it would appear that the HOA will be off the hook.
Some dry lot owners point out that lakefront lot owners have the right to irrigate their landscaping by drawing free water from the lakes, but dry lot owners must use municipal water at considerable cost.
Interestingly, all six members of the 2005 committee were lakefront owners. When the new committee was appointed in 2007, eight of nine were lakefront owners. The ninth had a lake view from the rear of his house.
The Board itself is made up of 60% dry lot owners. In a straw poll, 80% of the Board favored piecemeal lake bank restoration over many years, financed by regular assessments rather than doing it all at once via a special assessment.
It appears that those who favor a $750,000 special assessment face an uphill battle. We’ll see next month.
Meanwhile, what’s up with the lake bank erosion issue in your community?

It's not the lake bank erosion, it is the inconsistent level of the water in these retaining ponds. If the water level was consistent you would not have an eyesore.

The geo-tube is an excellent choice, it utilizes the sediment from the bottom of the lake and you can have it built to a grade that is easily maintainable. ANCHOR MARINE did some great bank restoration in Coral Springs and Margate the past 2-3 years and the results have been excellent.
Erosion is cause by numerous factors -- wave/wind action along the shoreline, use of herbicides over many years that degrade the shoreline and the composition of the bank itself.
In all fairness, the adjacent property owners are the ones who should be assessed. They will be the 'only ones' who directly benefit from the improvement. Surveys of each lot or parcel will need to be done. The board will need to decide how much shoreline is going to be restored. Otherwise there will be gripes over this lot got 5 feet added and that one got 15. People are going to complain someone got more than the other. Its not a simple project.
You'll also need to consider the irrigation pipes drawing water from the lakes. Who is going to reset them? If one breaks under the geo-tube it could compromise the section of tube for many lots. I have already seen an 'ignorant' homeowner cut right through one of these tubes because he wanted to plant a tree by the water. He ended up with a huge depression as the material washes out from rain and sprinkling and growth of the tree.
A suggestion on the sprinkler pipes is to lay the tubes over the pipes but cut the pipe at the end of the new bank and put a 'quick-connect' on so that the check valves and screens can be maintained by the owner without disturbing the geo-tubes. Cover the HOA by mandating no digging from where the tubes begin, or repair cost will be assessed to the applicable owner. The HOA may look into grants or other governmental financial assistance to finance the improvement. Unless somebody's pool or house is about to be absorbed into the lake it seems you have time to do a little more due diligence and research on this project.
Good luck and God bless.

I too live on a lake further north and erosion severely eroded our banks as well.
I sit on the end of the lake and continually get wind and wave action that definitely eroded the shoreline. I agree with the poster above that stated one of the big problems is the erratic water levels that at times seem to undercut the shore.
This past summer our local government had geo tubes installed to combat this problem and it has made a tremendous difference. Besides getting back about 4' of washed away property, you can't tell they even did it.
They dredge up material from the lake bed, mix it with a little concrete and pump it into tubes that then set as hard as rock. Two days later, in came sand placed into a second geo tube and then sod. Bang, everything done with minimal interference and it looks great!
Don't hesitate to do the geo tube procedure ... the longer you wait the more it will cost. I recommend it wholeheartedly.
