About this file
This is an Addendum (Construction Techniques Memo) issued by the St. Johns Water Management District and Clay County Engineering Department for the Lake Geneva Restoration Project (GSSL-019-232368-1). The memorandum, dated March 25, 2025, outlines specific construction techniques and erosion control measures that the contractor must implement during tree removal and vegetation clearing operations across approximately 342 acres of exposed lakebed. Key requirements include installation of silt fence in accordance with Florida Department of Transportation standards along perimeter areas bordering the water's edge prior to vegetation removal, prohibition of soil surface damage or rutting within wetland and surface water areas, cutting trees and shrubs at ground level while leaving stumps in place, disposal of all debris in upland areas, and adherence to property line boundaries. The Clay County Engineering Department will conduct regular inspections of restoration areas and access points using certified erosion and sediment control inspectors to ensure compliance with environmental and regulatory standards.
The addendum emphasizes strict environmental protections to prevent violations of state water quality standards during Phase I of the Lake Geneva Restoration Project. All access points to the restoration area must comply with FDOT erosion control specifications, including prevention of sediment tracking onto paved roadways. The contractor is prohibited from removing stumps, root raking, or altering soil surfaces, and all vegetation removal must be confined to the property owner's direct riparian interest on the lake. This technical guidance document serves as mandatory compliance documentation for the selected contractor and establishes the framework for executing tree removal operations safely while maintaining ecological integrity and regulatory compliance throughout the project duration.

RE: Lake Geneva Restoration Project GSSL-019-232368-1 PAC Construction Techniques Memo
Ms. Wentzel, The tree removal methods, and installation of erosion control measures by the contractor will ensure the proposed Lake Geneva Restoration Project will not result in violations to the state water quality standards.
Prior to any removal of vegetation in a restoration area, the contractor shall place silt fence, in accordance with Florida Department of Transportation (FDOT) Standards and Specifications (latest revision), along perimeter areas that border the existing waters edge. The location of the proposed silt fence is shown on the drawing included.
Additionally, the contractor shall adhere to the following measures:
• Access within the wetland/surface water for tree/vegetation removal shall not damage, alter the soil surface or rut the wetlands/surface waters.
This includes all areas waterward of the wetland delineation, safe upland line and/or ordinary high-water line, whichever is higher.
• Trees and shrubs shall be cut off at the ground surface or higher.
Stumps must remain in place. Any removal of stumps, root raking or alteration to the soil surface is prohibited.
• All debris, including the fallen trees, branches, shrubs, leaf material, etc. from the downed vegetation the wetland/surface water must be disposed of in an upland area
• All removal of trees and shrubs must be kept within the requestor’s property lines. If removal of vegetation is proposed below the established ordinary high-water line, work must be limited to the property owner’s direct, apparent riparian interest on the lake.
• All access points to the restoration area must also adhere to FDOT erosion control specifications, including prevention of tracking sediment onto a paved roadway.
The Clay County Engineering Department will provide regular inspections of the restoration areas and access points by certified erosion and sediment control inspectors.
