Committee Goals
The LACA Land Use Committee Guidelines support five key principles for future “safe growth”
Ensure Safe Navigation by providing reasonable watercraft access lanes away from the shoreline
Establish Shoreline Stabilization techniques that prevent erosion and dissipate wave action while maintaining existing shoreline boundaries
Maintain Natural vegetative Buffers that provide Erosion Control and reduce sediment accumulation
Eliminate Dredging and excavation activities that adversely affect the environmental ecosystem
Develop Good Neighbor Policies that preserve water views, aid water access, reduce shoreline clutter, and protect water quality by ensuring proper handling of waste

Approach to Guideline Development
Seek out Shoreline development guideline examples from similar Lakes
Claytor Lake, Pulaski County, VA Smith Mountain Lake, VA (American Electric Power)
Lake Gaston and Roanoke Rapids Lake, NC & VA Duke Power, NC (16 lakes Charlotte area) Richland-Chambers Lake, TX
Compare and assess – select appropriate principles and guidelines for Lake Anna
Compare to exiting county ordnances (Spotsylvania, Louisa, Orange)
Debate appropriate guideline metrics for Lake Anna shoreline and watershed
Select guidelines that are “middle of the road” centrist Recommend strawman to LACA BoD for review/adoption as
beginning for community discussions
LACA BoD Adopted Strawman on 8 Sep 2003

Summary of Suggested Guidelines (1 of 3)[for new development only]
Ensure safe navigation by providing reasonable watercraft access lanes away from shoreline No dock, pier, or boat shelter should protrude more than 100 feet into
the water from the normal waterline
A minimum of 33% of a cove (a minimum of 40 feet) must be left open for safe watercraft passage
Establish shoreline stabilization techniques that prevent erosion and dissipate wave action while maintaining existing shoreline boundaries All shoreline with up slope greater than 4 to 1 (more than 12” vertical
rise within 48 inches horizontal upslope from the water line) within the first 10 feet landward from normal water level must be stabilized as a condition for issuance of a dock, pier, or boat shelter permit
Bulkhead fill must be clean material with fabric cloth and gravel placed landward of the bulkhead prior to clean fill placement.
Preserve right of appeal and allow for exceptions based on certified need
Land Use Committee
Slide 7 of 11
Summary of Suggested Guidelines (2 of 3)[for new development only]
Maintain natural vegetative buffers that provide erosion control and reduce sediment accumulation No healthy trees with diameter measure of 6 inches or greater at
chest height may be cut within the first 100 feet landward from the normal waterline
Selective clearing of trees with diameter measure of 6 inches or greater measure at chest height may be allowed to facilitate dock construction (not allowed in Spotsylvania County)
Eliminate dredging and excavation activities that adversely affect the environmental ecosystem All dredging and excavation is by permit from Dominion Power
Excavation is not allowed for channeling to create additional shoreline or to materially alter the normal waterline
Preserve right of appeal and allow for exceptions based on certified need
Land Use Committee
Slide 8 of 11
Summary of Suggested Guidelines (3 of 3)[for new development only]
Develop good neighbor policies that preserve water views, aid water access, reduce shoreline clutter, and protect water quality by ensuring proper handling of waste A dock, pier, or boat shelter must maintain a side setback of 15’ from the
water access extension line (extended into the water). Where a water access extension line is not specified the setback will be from the property lines extended.
A waterfront lot must have a minimum of 55 feet of shoreline (as measured at the waterline at normal pool – 250’ AMSL on public waters and 251’ AMSL on the waste heat treatment facility waters) to have a dock, pier, or boat shelter.
Private community common areas with multiple boat slips shall have sanitary facilities
The covered area for all boat shelters must not contain more than 8SF for every foot of shoreline owned (as measured at the waterline at normal pool – 250’ AMSL on public waters and 251’ AMSL on the waste heat treatment facility waters)
Placement of subdivision common area boat ramps must be well away from sharp bends, bridges, dikes, and other passage choke points.
Preserve right of appeal and allow for exceptions based on certified need

Next Steps
Brief other stakeholders in the Lake Anna Community LAAC Principals County Planning Directors (Louisa, Spotsylvania, Orange) POA BoDs for Lake Anna Subdivisions Lake Anna Economic Development and Tourism Partnership Staff of Regional Planning Districts Staff of Regional Soil and Water Conservation Districts Selected Louisa Supervisors Dominion Virginia Power Members Lake Anna Roundtable (Lake Anna Watershed Land Use
Plan)
Find out which guidelines are strongly supported, and which ones are highly controversial Identify guidelines that are controversial for the near term Publish revised suggested guidelines of consensus views and items
which LACA is strongly committed to Present to county governments with plea to adopt as Ordnances
common and uniform to the three Lake Anna stakeholder counties
Land Use Committee
Slide 10 of 11
Recommendations
A copy of the LACA Suggested Guidelines is offered to each LAAC member
After reflection, we encourage LAAC members to provide feedback on those provisions they most strongly support, and those they feel are least desirable
Adopt most favored provisions as part of Lake Anna Roundtable Lake Anna Watershed Land Use Plan
LACA/LAAC introduce most favored provisions to county governments as “common universal tri-county” standards for placing in Shoreline Development and Watershed Best Practices Ordnances

Bulkhead or rip-rap material shall be placed channelward of the side extension property lines and positioned in a reasonable alignment of normal lake level elevation, for the sole purpose of bank stabilization
Bulkhead fill must be clean material with fabric cloth and gravel placed landward of the bulkhead prior to clean fill placement.¹
Shoreline stabilization that alters the shoreline boundary by more than five feet landward or channelward from normal water level is not permitted
Debris (except broken concrete), tires, car bodies, etc. are not acceptable for banks stabilization activity along Dominion Power’s shoreland¹

Suggested Guidelines (2 of 3)
Maintain natural vegetative buffers that provide erosion control and reduce sediment accumulation No healthy trees with diameter measure of 6 inches or greater at chest height may be cut
within the first 100 feet landward from the normal waterline Selective clearing of trees with diameter measure of 6 inches or greater measure at chest
height may be allowed to facilitate dock construction (not allowed in Spotsylvania County) A developer, contractor, or resident may apply by permit to the county for an alternate
clearing plan. A professionally engineered site plan must be prepared for the proposed alternate clearing plan. The plan must provide erosion control through the use of vegetative or structural sediment buffers.
Eliminate dredging and excavation activities that adversely affect the environmental ecosystem All dredging and excavation is by permit from Dominion Power Dredging and/or excavation exceeding 150 cubic yards requires permit from Dominion
Power and the Corp of Engineers. Dredging and excavation can only be done in front of applicant’s property within the property water extension lines or property lines extended
Double handling of materials is not allowed An adequate upland disposal sight a minimum of 100’ from the normal shoreline is
required and must be clearly defined in request for permit Excavation is not allowed for channeling to create additional shoreline or to materially
alter the normal waterline Reclamation of eroded shoreline to the originally surveyed boundary will be allowed based
on validation from a professional surveyor to a maximum reclamation of 10 feet perpendicular to the normal shoreline

Suggested Guidelines (3 of 3)
Develop good neighbor policies that preserve water views, aid water access, reduce shoreline clutter, and protect water quality by ensuring proper handling of waste A dock, pier, or boat shelter must maintain a side setback of 15’ from the water access
extension line (extended into the water). Where a water access extension line is not specified the setback will be from the property lines extended.
A waterfront lot must have a minimum of 55 feet of shoreline (as measured at the waterline at normal pool – 250’ AMSL on public waters and 251’ AMSL on the waste heat treatment facility waters) to have a dock, pier, or boat shelter.
Maximum height of all private recreational facilities located over the water is not to exceed 18’ above normal water level. No enclosed second story room is allowed.
The covered area for all boat shelters must not contain more than 8SF for every foot of shoreline owned (as measured at the waterline at normal pool – 250’ AMSL on public waters and 251’ AMSL on the waste heat treatment facility waters)
Boat docks, piers, or boat shelters constructed in a community common area for off-water lot owners must comply with water access lane requirements (maximum protrusion and minimum safe passage lanes) and maintain 30-foot side setbacks from the water access extension lines or property lines extended where water access extension lines are not specified. Common area refers to properties and/or facilities owned and managed by a property owners association.
If boat docks, piers, or boat shelters are provided for subdivision off-water lots they can only be constructed in the waters abutting the designated community common area.
Placement of subdivision common area boat ramps must be well away from sharp bends, bridges, dikes, and other watercraft passage choke points. Wherever possible boat ramps should be placed in protected areas where wave action from passing watercraft will have minimal effect on safety of launching and recovery operations.
Private community common areas with multiple boat slips shall have sanitary facilities, VDH required and approved dump and/or pump-out facilities, and fire department approved dry hydrant facilities as prescribed by state and local code.

Smith Mountain Lake
Smith Mountain Lake is 40 miles long, covers 20,600 surface acres, with 500 miles of shoreline. It is nestled within the mountains of southwestern Virginia. Smith Mountain Lake was created to generate electricity, and to help manage water flows downstream and nearby. The damming of the Blackwater and Roanoke Rivers formed Smith Mountain Lake in a filling process that began September 24, 1963 -- and took nearly three years to complete on March 7, 1966.
