1.0 Executive Summary 

The Kline Island shoreline banks have been under continual erosion for many years due to wave action caused by wind‐energy and recreational boating. The southwest and northwest banks are the most severely eroded banks on the island. The bank erosion has slowly reduced the surface area of the island, damaged fishery habitat, increased turbidity, and released nutrients into the water.  Department of Natural Resources (DNR) Fishery Biologist, Jed Pearson, originally identified the severity of the bank erosion and contacted Lyn Crighton at The Watershed Foundation (TWF) to discuss  potential  programs  and  funding  sources  to  address  the  problem.    In  2013  a  report prepared by Mr. Pearson was completed which  identified the problem and provided potential solutions, Webster  Lake  Island Protection Project.   TWF  and  the  Epworth  Forest Conference Center identified two potential funding programs for controlling shoreline erosion in 2014.  Grant applications were submitted and funding was obtained to proceed with construction of Phase I.   Construction consisting of 290 feet of bank protection on the south and southwest sides of the island was completed in fall of 2015.  Grant applications were submitted and funding approved to proceed with construction of Phase II for an additional 290 feet of bank protection on the west side of  the  island. Construction was completed on Phase  II  in  January 2018.  In 2018 Epworth Forest Conference Center applied to the DNR Lake and River Enhancement (LARE) Program for funding  to  complete  Phase  III  of  the  island  project.    The  application  was  for  design  and construction of approximately 300 feet of bank stabilization on the west and southeast sides of the island.  Following final approval of the LARE funding, Epworth Forest Conference Center contracted S&L Environmental Group to design and construct the required activities to stabilize approximately 300 feet of shoreline banks from further erosion.  The design was completed and submitted in October 2018 and included: (1) construction of a bio‐engineered seawall consisting of a glacial stone toe‐wall   spanning approximately 200  feet of the southeast shoreline, 95  feet of glacial stone toe‐wall on the west shoreline, (2) installation of stone steps on the southern edge of the island for access, and (3) planting of native live stakes into the glacial stone toe‐wall.   All contract tasks were completed in December 2019.  

2.0 Project Purpose 

2.1 Objectives 

The objective of the construction project was to eliminate bank erosion on the shoreline of Kline Island by installing approximately 200 feet of bio‐engineered seawall on the southeast side, as well as 95 feet of bio‐engineered seawall on the west side and  install  island access stone steps on the southeast edge of the island.

2.2 Accomplishments 

300  feet  of  the west,  east,  and  southeast  banks were  stabilized  from  further  erosion  by installing a glacial  stone  toe‐wall, planting  live  tree  stakes near  the  top of  the  stone, and installing  island  access  stone  steps.    The height of  the  stone  toe‐wall was determined by calculating wave height.  

3.0 Project Description 

3.1 General Location 

The Kline  Island Phase  III project  is  located on Webster Lake  in North Webster, Kosciusko County, Indiana.

 Figure 2 ‐ Site Specific Location Map 

3.3 Project Interest  

A coordinated effort between Epworth Forest Conference Center, The Watershed Foundation, and Webster Lake Conservation Association allowed the project to become a reality.  These agencies were involved in the review of the design drawings and construction activities.  In‐kind services were provided by Epworth Forest in the form of acquiring construction staging area and access.  Funding contributions and project support were received through the LARE Program.   

 

4.0 Project Construction 

The following construction activities were completed according to the design plans.  Adjustments were made during  construction due  to  site  conditions,  as  shown  in  the As‐built Drawings  in Appendix A of this report.  The most notable change to the design plans was the location to install the stone toe‐wall.  Severe shoreline erosion occurred on the east side of the island subsequent to  the  completion  of  the  design  plans.    It was  agreed  upon  by  Colby  Stanger  of  S&L, Doug Nusbaum of LARE, and Lyn Crighton of TWF to shift 130 feet of shoreline stabilization from the southeast side of the island to the east side to prioritize the location of increased erosion.  

4.1 Mobilization 

The construction staging area and  lake access was provided by Epworth Forest Conference Center.  This site provided a location to load the barge with the glacial stone to be transported to the island and for general construction storage.

4.2 Glacial Stone Installation 

6‐inch to 12‐inch glacial stone was imported and installed on a total of 300 feet of shoreline bank as shown on the As‐built drawings.  The size, slope, and height of the stone toe‐wall was designed based on wave height calculations from wind energy and recreational boating.  4.3 Island Access Stone Step Installation 

A set of five stone steps constructed of Tennessee Stone were installed on the southeast side of the island to allow safe and easy public access.  The Tennessee Stone slabs used for steps were placed on a glacial stone base for support and to prevent wave action from undercutting and damaging the stability of the steps.  4.4 Native Plant Installation 

100 live tree stakes were planted near the top edge of the stone toe‐wall.  The live stakes were planted in late December on 3 foot spacing.  The plant materials used are shown in Appendix B.  4.5 Restoration 

All disturbed areas within  the access and  staging areas were  returned  to pre‐construction conditions. 

 

5.0 Project Logistics 

5.1 Permit Requirements 

The Indiana DNR Water Division, Lake Preservation Act Permit was acquired for the project.  Requirements of the approved permit was to provide a Public Notice to adjacent property owners to allow them the opportunity to review and comment on the proposed project.  A copy of the permit is included in Appendix E.  5.2 Construction Timing 

Construction activities began the first week of December 2019 and were completed in three weeks when the dormant live tree stakes were harvested and installed.  5.3 Project Contractor 

S&L Environmental Group (S&L) was awarded the bid for the design and construction of the project and was determined to be the preferred consultant to provide construction oversite.   5.4 Construction Methods 

A barge was used to transport the glacial stone for the stone toe‐wall from the lake access to the island.  Construction equipment used the same barge to construct the stone toe‐wall from the water which minimized the disturbance of the island.

6.0 Future Project Inspection and Maintenance 

6.1 Post‐construction Inspection 

Post‐construction inspection shall be performed at a minimum of twice a year, spring and fall.  During the first year following construction it is recommended to complete an inspection after each significant storm event.  If repairs are required, they should be made immediately.  6.2 Vegetative Inspections and Maintenance 

Vegetative practices will be  inspected following the first growing season, spring of 2020 to ensure  successful  germination.    If  the  vegetative  cover  is not  75%  established,  additional seeding may be required.  Live tree stakes will need to be inspected after ice thaw in the spring of 2020 and after heavy boat traffic in the fall to verify planting success and survival rate.  6.3 Structural Inspections and Maintenance 

Structural improvements, glacial stone toe‐wall including tie‐ins on both ends will need to be inspected after the ice on the lake thaws each spring.  Replace any stone that may have been displaced by  ice  forming or  thawing events.  Inspect  the  stone  toe‐wall after peak boating periods and after all major storm events to determine if the toe‐wall was adversely affected by the wave action.  Buoys should be moved a greater distance from the island if wave action from boats are adversely affecting the stone toe‐wall.  

7.0 Estimated Load Reduction (Post‐construction) 

The EPA Region 5 Load Reduction Program was used to estimate the load reductions of sediment, phosphorous,  and  nitrogen.    The  shoreline  Sediment  Load  Reduction  is  0.5  ton  per  year, Phosphorous Load Reduction is 0.4 pounds per year, and Nitrogen Load Reduction is 0.8 pounds per year.  See Appendix F for the detailed Worksheet.

Class 1 NonwovenTensile Strength 180 lbs minBursting Strength 320 psi minElongation 50% maxPuncture 80 lbs minUltraviolet Light Resistance 70% min tensile strength retainedPermittivity 0.7 second min

3. SURFACE PREPARATIONThe surface on which the geotextile is to be placed shall be graded as shown on the sign plans. The surface shall bereasonably smooth and free of holes, sharp objects and projections.

4. PLACEMENTa. General

The geotextile shall be placed on the prepared surface at the locations and in accordance with the details shownon the design plans. The geotextile shall be unrolled along the placement area and loosely laid (not stretched) insuch a manner that it will conform to the surface irregularities when the glacial stone is placed against it. No cutsor punctures will be permitted. The geotextile may be folded and overlapped to permit proper placement in thedesignated area.

b. Slope ProtectionThe roll or panel length shall be placed parallel to the direction of water flow. The minimum overlap shallbe 18”, in any direction. The geotextile shall not be placed until it can be anchored and protected with theintended covering within 48 hours. If the geotextile will not be covered within 48 hours, a temporary coveringwill be used for protection from ultraviolet light.

Securing pins shall be placed along the edge of the panel to adequately secure itduring placement. At vertical laps, securing pins shall be inserted through both layers along a line through theapproximate midpoint of the overlap. At horizontal laps and laps across slopes, securing pins shall be insertedthrough the bottom layer only. Securing pins shall be placed along a line approximately 2 inches in from the edgeof the outer limits of the placed geotextile at intervals not greater than 12 feet.Additional pins shall be installed as necessary to prevent any slippage of the fabric,regardless of locations.

Kline Island Phase III – Webster Lake Bank Stabilization – Engineeer Assessment

September 2018

1. Composition of existing shoreline terrain – The northwest side of the Island consist of 10-16 ft. nearly vertical and non-vegetated banks. The East side of the island consists of 3-4 ft. non-vegetated banks. The soil structure at the Ordinary High Water Mark (OHWM) consist of stratified gravelly course sand to course sand, which is very easily eroded. Shrubs and trees exist at the top edge of the vertical banks. Water depth along the shoreline is shallow (1-2 ft.) 20-25 ft. lakeward due to the bank sloughing into the lake as a result of being undercut from wave action.

2. Impacts due to wind and wave action – The calculated wave height from wind is 1.8 ft. The wave action is undercutting the easily erodible soils of the bank allowing the soil above to slide into the lake along with trees and shrubs located at the top edge of the bank. The wave action and resulting bank erosion damages fish habitat and recreation activities by increasing turbidity, up-rooting trees and shrubs and decreasing aquatic and wetland plants.

3. Severity of erosion and need for bank stabilization – The on-going erosion process is severe and will continue at an accelerated rate if not stabilized. The severity of the erosion is evident from the number of trees and shrubs which have been up-rooted or have exposed roots. It is estimated the banks may be receding at 3-6 inches per year in areas.

4. Suitability of materials to armor and provide bank protection – A bio-engineered seawall is recommended, including planting native live stake shrubs within a glacial stone toe wall. D50-8” glacial stone is recommended based on the 2H:1V runner-up slope and the significant wave height of 1.8 ft. The stone will prevent further undercutting and sloughing of the banks, while presenting a natural appearance. Native plant materials placed within the glacial stone will help provide additional stability and provide a natural shoreline appearance. Sloping of the bank above the glacial stone is not recommended due to the significant loss of trees, shrubs and associated upland habitat.
