Shoreline Management Guidelines Major changes to be implemented in September 2006

Duke Energy operates a comprehensive shoreline management program on its reservoirs. This program depends on the Shoreline Management Plan (SMP) and Shoreline Management Guidelines (SMG) to balance private and public access while protecting the environmental, public, recreational, cultural and scenic values of the hydroelectric project. The following is a list of major changes to the SMG that will be implemented beginning September 1, 2006. (This is intended to reflect the more significant changes and does not include “all” changes.)

Shoreline Stabilization

  1. No new seawalls will be allowed where eroded bank is less than 3' high.
  2. Bio-engineering or enhanced rip rap are the only stabilization techniques allowed in areas where the eroded bank is less than 2' high.
  3. Bank re-shape by cut/fill will be considered if it is allowed by local buffer regulations.
  4. There is to be no shoreline stabilization within 50' of an area classified as Environmental in the SMP.
  5. Impacts to water willow beds should be avoided but access is still allowed.

Vegetation Management

  1. Protection of vegetation within the Project boundary (below full pond on Catawba-Wateree)
    1. No removal of native vegetation less than 4’ tall.
    2. Existing forest floor humus/litter shall remain undisturbed.
    3. Footpaths limited to 4’ wide.
    4. Trees removed greater than 3" diameter at breast height (dbh) must be replaced with an ecological equivalent.
    5. Trees greater than 10"dbh can not be removed unless a danger to an individual or structure.
  2. View sheds
    1. May be created by consulting with and receiving written authorization from a Duke Energy Lake Services representative.
  3. Dead trees
    1. Trees that have fallen into the water but are still attached to the shore should remain for fish habitat.
    2. Dead standing trees should remain as snags for wildlife habitat.
  4. Turf grasses shall not be planted within the Project Boundary.
  5. No mechanical clearing within the Project Boundary except to gain access for shoreline stabilization purposes.

Private Facilities

  1. Average-sized moored watercraft considered in determining pier limitations (e.g., 1/3 cove width or 120’ length requirements).
  2. Property lines will be projected into the lake in both North Carolina and South Carolina to determine buildable area for pier and other construction/stabilization activities.
  3. Minimum of 25’ clear maneuvering area between new piers/docks in the backs of coves.
  4. No new piers where cove width is 25’ wide or less.
  5. No new boat ramp construction at private residential lots.
  6. Facility maintenance consideration increases from the existing 10% limitation to 25% for any component (e.g., decking, joists, roof, handrails, etc.) or any combination of components, or 100% of any single component, or 100% replacement of any one structure (e.g., walkway, float, covered slip, etc.) of the total facility in a calendar year. All replacement of pilings and flotation is considered maintenance.
  7. Minimum lot width necessary for consideration of a pier increased from 75’ to 100’ of shoreline.
  8. No new structures within 50’ of an area classified as Environmental in the SMP.

Consequences for violations

  1. More specific penalties for non-compliance.
  2. Ability to withhold permit consideration for up to 5 years if a violation has occurred.

Marina Facilities

  1. Incentive program for Residential Marina developers to encourage preservation of shoreline and/or the establishment of buffers upland of the Project Boundary in a development.
  2. No new, expansions or rebuilds of marina facilities in narrow coves (i.e., coves 300’ in width or less).
  3. True Public Marina requires both restrooms and publicly available pumpouts for disposal of wastes from marine sanitation devices.
  4. Exceptions for True Public Marinas allow total facility length of up to 200’ from shore (full pond).
  5. Commercial Marinas with gas dispensing facilities must provide adsorbent material within the slips dedicated for refueling to prevent petroleum contamination.
  6. No new, expansions or rebuilds of marina facilities within 50’ of an area classified as Environmental in the SMP.

Excavation

  1. Excavation is not allowed within water willow beds except as necessary to maintain access to previously approved facilities.
  2. New excavation activities are not allowed within 50' of an area classified as Environmental in the SMP except where necessary to allow continued access to a previously approved facility.
  3. A copy of the contract between the applicant and the contractor must be provided with the application to dredge and that contract must articulate the scope of work.
  4. Potential to extend the dredge application for 12 months if requested in writing within the original 18 month timeframe.

Conveyance Program

  1. A Lake Facility Safety Plan will be required for most conveyance activities (e.g., water intake, public bridge, effluent outfall, etc.).
  2. All submerged utility lines must be buried a minimum of two feet below the lakebed to a depth determined by the highest level of water in a reservoir below which a large public water supply intake, industrial intake or regional power plant intake located on the reservoir will not operate at its Duke Energy-approved capacity.

Miscellaneous Lake Uses

  1. Exceptions for depth requirements for dry hydrants that include a Lake Facility Safety Plan.
  2. Two (2) horsepower limit for private water withdrawal irrigation pumps.
  3. Fish attractors may be constructed adjacent to existing facilities.
  4. Heat pump coils and Geo-thermal units may be placed beneath existing permitted structures or anchored adjacent to existing piers.

Shoreline Management Plans (Changes for C-W SMP September 2006)

Catawba-Wateree

  1. Two new habitat classifications- Bottomland Hardwood Areas and Natural Isolated Berms have been added.
  2. Some shoreline has been reclassified based on narrow cove criteria (i.e., < 300’ wide) to further limit multi-slip marina and marina boat ramp access in narrow coves.
  3. Improved mapping accuracy of the shoreline and Project Boundary based on Light Detection and Ranging (LiDAR) technology and higher resolution digital aerial photography.

Keowee-Toxaway

  1. A Shoreline Management Plan is being developed for Lake Keowee. This plan will be implemented on or before December 31, 2006.
  2. The entire shoreline of Lake Keowee (including islands) has been video taped to document existing conditions of the shoreline and existing facilities.
