Introduction – Landshore Enterprises, LLC:

Landshore Enterprises, LLC (Landshore®), with offices in Fort Lauderdale, Florida and headquartered in Venice, Florida, is a turnkey national design-build environmental company specializing in shoreline erosion control, repair and restoration challenges. Landshore® uses non-structural, bioengineering and bio- technical methods to fulfill the demands of our clients.

Established over two decades ago, we have provided our services of excellence to golf courses, homeowner associations (managed properties), private residences, and governments in more than 10 states.

Landshore® is very conscientious about completing projects that reflect professionalism to the highest degree. We take a great deal of pride in each contracted service, no matter how large or small the project is. Our engineering expertise ensures that we will provide you with the best possible solution at the best possible price based on thorough research, investigation, and data interpretation from the job site.

Because of our engineering practices, our clients are assured that their shoreline erosion solution will endure for the longest amount of time possible. Additionally, the number of construction hours required for job completion are billed accurately and even the precise amount of quality materials for the best solution are deployed.

Our talented group of employees, research and investigate public records on the subject site, conduct surveys, perform various tests such as measuring soil density and analyze results. From all the compiled information and subsequent analysis, we gain an understanding of the historical and current nature of the erosion changes concerning water levels, the amount of erosion loss over time, the slope of the eroded shoreline, and the stability of the surrounding soil.

We have the expertise, resources, technology, and collaborative insight to create designs and solutions that far exceed our client’s expectations. Due to our extensive experience in resolving various erosion problems around the nation, Landshore® is proud to guarantee complete satisfaction on ALL projects.

Objective:

Our firm was contracted by the District to perform engineering services with the purpose of producing engineered soil erosion control plan, quantity take-off, and preliminary opinion of probable construction costs. Our main goal is to compile a report with soil erosion challenges identification, calculated stability, and recommended solutions, if any, to restore the lake shorelines into compliance, wherever economically feasible.

Existing Conditions:

At the specific request of the District seeking possible solutions to address slope stability, public safety, and aesthetics issues of the shorelines, the subject site was assessed by our team of key professionals. It was found to exhibit signs of loss of valuable soil above the Mean High-Water Level, underwater shelf reposing itself where the shoreline has encroached closer to structures, change in embankment slopes, and unstable edge of embankment. Elements contributing to the embankment erosion are seepage, sheet flow, fluctuation of water levels, and wave action.

General:
The soil types are the following:
USDA Type 54-Marly Silt Loam, according to the US Department of Agriculture.
USDA Type 58-Cooper Town muck, according to the US Department of Agriculture. Refer to Exhibit 2 – Soil Types
All the Vertical Datum are reference from National Geodetic Vertical Datum 1929 (NGVD29).
According to our survey, all seven lakes have areas that are below the permitted top of bank elevation. Per originally permitted set of engineering drawings the top of the bank should be at elevation 9.50’ NGVD29.
Overall, to the naked eye, the embankment slopes look in good condition. However, the shorelines are eroding rapidly. The soil tends to repose itself to its natural stability, making the slopes steeper over time and not in accordance to its original design.
The lakes were numbered based on the permitted set of drawings.

Lake 1: The shoreline length is approximately 774 linear feet. Lake 2: The shoreline length is approximately 2,118 linear feet. Lake 3: The shoreline length is approximately 1,248 linear feet. Lake 4: The shoreline length is approximately 1,972 linear feet. Lake 5: The shoreline length is approximately 2,338 linear feet. Lake 6: The shoreline length is approximately 1,677 linear feet. Lake 7: The shoreline length is approximately 1,872 linear feet.

Figure 6: Drawing from permitted plans.

All lakes:

The following is the scale used to identify the conditions of the lakes and our recommendations:

High – Immediate attention recommended.
Medium – Often monitoring is recommended, due to potential weather inclement. 1 to 2 years attention.
Low – Monitoring only. Attention is expected to be needed within 3 to 5 years.

Recommended priority of shoreline restoration:

High Priority:
Lake 4
Based on our analysis, we recommend this lake’s shoreline be the first to be restored, specifically on the residential side. We found that the slope from the top to the water’s edge is very steep. In addition, at the edge of the embankment, there are steep drops of +/- 2 feet. If no action is taken, the shoreline will keep eroding at an accelerated rate, creating a steeper slope from the top because the soil will repose itself.

Medium to High Priority:
Lake 5
Lake 6
Lake 2
Note: We recommend that the community acts on these lakes based on budgets.

Medium Priority:
Lake 1
Lake 7

Low Priority:
Lake 3

See below photos and a topographic drawing of the priority areas. The lakes below have been listed in order of recommended repairs.

Figure 28: Types of soil erosion

Detachment and movement of soil or rock fragments by water, wind, or gravity. The following terms are used to describe different types of soil erosion:

Accelerated Erosion – Erosion much more rapid than normal, or geologic erosion, primarily as a result of the influence of the activities of man, or in some cases, of other animals or natural catastrophes that expose base surfaces, for example, fires.

Gully Erosion – The erosion process whereby water accumulates in narrow channels and, over short periods, removes the soil from this narrow area to considerable depths, ranging from 1 to 2 feet to as much as 75 to 100 feet.
Natural Erosion – Wearing away of the earth’s surface by water, ice, or other natural agents under natural environmental conditions of climate, vegetation, etc.; undisturbed by man.

Normal Erosion – The gradual erosion of land used by man which does not greatly exceed natural erosion.
Rill Erosion – An erosion process in which numerous small channels only several inches deep are formed; occurs mainly on recently disturbed and exposed soils.

Sheet Erosion – The removal of a fairly uniform layer of soil from the land surface by runoff water.
Splash (Seepage) Erosion – The spattering of small soil particles caused by the impact of rain drops on wet soils. The loosened and spattered particles may or may not be subsequently removed by surface runoff.

Recommended Erosion Control Elements

Landshore® has expertise in design and installation of different remediation applications for slope stabilization and erosion control, including Articulating Concrete Block mat, bulkhead, Concrete Cloth™, Eco-Filter Tube®, Erosion Control Panel, Flexamat®, Flex MSE®, Geo Web®, gabions, Hydrotex™, reinforced concrete wall, rip- rap, sand cement wall, sheet piling, Turf Reinforcement Mat, littoral planting and others.

After performing a cursory review of several alternatives, it is our professional opinion, to the best of our knowledge and belief that present slope condition may be remedied by utilizing Eco-Filter Tube® and Concrete Block Mat (Flexamat® or ShoreFlex®), which installation is hereby recommended as most viable solutions and are described below.

Eco-Filter Tube (EFT®):
EFT® or approved by Engineer equal product construction uses a woven or non-woven geotextile fabric that is formed into the shape of a tube. The tube container is filled with sand by direct coupling to a hydraulic dredge. The EFT® is designed to retain the granular fill portion of the dredge slurry, while appropriately sized openings in the material allow the excess water in the slurry to permeate through the tube walls. The procedure can be implemented in both dry and underwater conditions. The tubes can be fabricated in various circumferences, which, when inflated, will form a roughly elliptical shape. The EFT® system consists of a spun bound polyester filter fabric that is sewn together to form a tube which is placed along the water’s edge and filled with sand to form an erosion barrier that after consolidation has the characteristics of a permeable, gravity type retaining wall.
Some EFT® benefits include:
Sand and geo-textile materials used in the tubes are essential to allow proper drainage and ensuring an environmentally friendly erosion control solution.
The sand in the tubes functions as a filter for underwater seepage.
The EFT® solution enhances the quality of the lake water as it keeps environmental threats from entering the body of water.
EFT® installation bypasses the need to bring heavy equipment to the job site, preventing the possibility of damage from the large weight of the equipment.
EFT® is one of the most economical embankment restoration solutions.
