Building on or near a TVA reservoir is not as simple as setting posts, pouring concrete, or calling a dock builder. On many local lakes in the Tennessee Valley, shoreline work must be reviewed and approved by the Tennessee Valley Authority before construction begins.

That approval is commonly called a Section 26a permit.

For lake property owners, contractors, marina operators, and community associations, the permit process can feel confusing at first. The good news is that most projects follow a predictable path. If you know what TVA reviews, what documents to gather, and when to apply, you can avoid delays, redesigns, and costly do-overs.

This guide explains what Section 26a permitting covers, when you need approval, and how to prepare a strong application for work on local TVA-managed lakes.

Many shoreline projects on TVA reservoirs need approval before work begins.

What TVA Section 26a permitting means

Section 26a comes from the TVA Act. It gives TVA authority to review certain construction, excavation, fill, and shoreline changes in or along the Tennessee River system and TVA-managed reservoirs.

The purpose is not just paperwork. TVA reviews shoreline projects to protect:

• Navigation

• Flood control

• Water quality

• Public land and reservoir operations

• Cultural and environmental resources

• Access and safety on the water

  
  

If a proposed structure or activity could affect a TVA reservoir, its shoreline, or its operating rights, TVA may need to approve it before any work starts.

A TVA Section 26a permit does not automatically replace every other approval. Depending on the project, you may also need authorization from a state environmental agency, the U.S. Army Corps of Engineers, a county building department, a local floodplain administrator, or a homeowners association.

This article is for general information only. For a specific property or project, confirm requirements directly with TVA and any other agency with jurisdiction.

Common projects that may need Section 26a approval

Many lakefront improvements fall under Section 26a review. If the work touches the shoreline, extends over the water, changes the bank, or places material in the reservoir, assume TVA may need to look at it.

Common examples include:

• Private docks and piers

• Boat slips and covered slips

• Boathouses where allowed

• Community docks and marina facilities

• Boat ramps

• Shoreline stabilization

• Riprap placement

• Seawalls or retaining structures

• Dredging

• Filling or grading near the reservoir

• Water intakes

• Utilities crossing or entering the reservoir

• Bridges, culverts, or causeways

• Floating cabins or floating structures where applicable

• Modifications to an existing approved structure

  
  

Even a repair or replacement can require review if the work changes the size, location, use, footprint, or materials of the existing structure.

For example, replacing a few damaged deck boards on an existing dock may be routine maintenance. Expanding that dock, adding a roof, moving it farther into the cove, or enclosing a slip is different. TVA will usually want to confirm that the change still meets shoreline and reservoir standards.

When you should contact TVA before doing work

The safest time to contact TVA is before you design the final project or hire construction crews. Early contact gives you a chance to learn whether your idea fits TVA guidelines before money is spent on materials, engineering, or site work.

Reach out early if any of the following apply:

• The project is on or near a TVA reservoir

• The property includes a TVA flowage easement

• The work extends over public water

• The shoreline will be disturbed

• Rock, soil, concrete, or other material will be placed near or below the waterline

• Trees or vegetation near the shoreline may be removed

• The project is larger than a simple repair

• The structure has not been previously permitted

• You are buying or selling lake property and need to verify existing improvements

  
  

Older docks and shoreline structures can create special questions. A structure may have been built years ago, before current standards, or without clear records. Do not assume that an existing structure is automatically approved. If the permit history is uncertain, ask TVA how to verify it.

Accurate site details help TVA understand the project and review it faster.

What TVA looks at during review

TVA reviews each project based on location, reservoir conditions, public interests, and the type of work proposed. The exact review can vary, but several issues come up often.

Property rights and reservoir rights

TVA will look at where the project sits in relation to property boundaries, public land, easements, and reservoir operating elevations.

A lakefront deed does not always mean a property owner controls all the land down to the water or under the water. Many TVA reservoirs include flowage easements, public land, or rights needed for flood storage and reservoir management.

Before applying, gather your deed, survey, subdivision plat, or any documents showing access rights. If a dock serves a lot that does not directly touch the reservoir, TVA may need more information about the legal right to use that shoreline.

Size, location, and use of the structure

TVA considers how far a dock, pier, ramp, or other structure extends into the reservoir and whether it affects navigation or neighboring properties. A narrow cove, shallow water, or busy channel can limit what is allowed.

The intended use matters too. A small private dock is reviewed differently from a community dock, commercial marina, or multi-slip facility.

Shoreline condition and erosion control

For bank stabilization, TVA looks at how the shoreline is eroding and whether the proposed fix is suitable. Riprap is common on many reservoirs, but the design still matters. TVA may review the length, slope, stone size, placement method, and whether vegetation should be protected or restored.

Hard walls, bulkheads, and major grading can receive closer review because they may change shoreline behavior, affect habitat, or shift erosion problems to nearby properties.

Environmental and cultural resources

Some projects require environmental review. TVA may look for wetlands, sensitive habitat, threatened or endangered species concerns, historic resources, or archaeological issues.

This is one reason not to clear vegetation, dig, dredge, or place fill before approval. Starting early can damage resources and make the permit process harder.

Reservoir operations and flood control

TVA manages reservoirs for several purposes, including flood control, power production, water supply, recreation, and navigation. Structures must not interfere with reservoir operations or create hazards during changing water levels.

Seasonal lake levels matter. A project that appears harmless during summer pool may create problems when water levels rise or fall.

Documents to gather before applying

A complete application is easier to review. Missing details are one of the most common reasons a permit takes longer than expected.

Before starting the application, collect as much of the following as you can:

• Property deed or proof of ownership

• Recent survey or recorded plat

• Site address or clear location description

• Parcel number if available

• Photos of the shoreline and proposed work area

• Drawings or plans showing dimensions

• A site plan showing the project in relation to property lines and the water

• Existing permit records, if any

• Contractor information, if a contractor is involved

• Details on materials, construction methods, and equipment access

• Authorization from the owner if someone else applies

  
  

For dock projects, include the length, width, roof size if any, number of slips, anchoring method, and distance from neighboring property lines or nearby structures.

For shoreline stabilization, include the length of shoreline to be treated, the type of material, the slope, and whether any vegetation will be removed.

For dredging or fill, expect a more detailed review. You may need drawings showing the amount of material, depth, disposal area, and equipment methods.

Clear drawings and photos can reduce back-and-forth during the permit review.

How to apply for a TVA Section 26a permit

TVA provides an application process for Section 26a review. The exact steps and forms can change, so always use the current TVA application system and instructions.

In general, the process works like this.

1. Confirm that the project is on a TVA-managed reservoir

Start by confirming the waterbody and whether TVA Section 26a applies. If the property is on a TVA reservoir or connected to the Tennessee River system, Section 26a approval may be required.

If you are unsure, contact TVA before assuming the project is exempt.

2. Define the project clearly

Write a simple project description before you apply. Include what you want to build, repair, remove, or change.

Avoid vague descriptions such as “improve shoreline” or “repair dock.” Be specific.

A stronger description might say that the project will replace an existing private dock in the same location, install riprap along a measured length of eroding shoreline, or add a single covered boat slip to an existing permitted pier.

3. Prepare drawings and measurements

You do not always need polished architectural drawings for a small private project, but TVA needs enough detail to understand the location and impact.

At minimum, your drawings should show:

• The shoreline

• Property lines if known

• Existing structures

• Proposed structures

• Dimensions

• Waterward extension

• Nearby docks or ramps

• Construction access

  
  

Photos are helpful when they show the shoreline from several angles. Take clear images from land and, if possible, from the water.

4. Submit the application through TVA’s current process

Use TVA’s official Section 26a application instructions. Attach the required documents and give accurate contact information.

If the application asks about other permits, answer carefully. TVA may coordinate with other agencies, but that does not mean every required permit is automatically covered.

Some projects may require a joint review with state or federal agencies. Larger projects, dredging, wetland impacts, or commercial uses often involve more review than a basic private dock.

5. Respond quickly to questions

TVA may ask for more information, revised drawings, proof of ownership, or clarification about construction methods. A fast, complete response keeps the review moving.

If TVA asks you to revise the project, do so before starting work. Building first and asking later can lead to enforcement problems, removal orders, or expensive changes.

6. Wait for written approval before construction

Do not begin work based on a phone call, assumption, or contractor estimate. Wait for written authorization and read the permit conditions closely.

Permit conditions may cover construction timing, approved dimensions, stabilization methods, erosion controls, vegetation protection, or limits on future changes.

Keep the permit with your property records. Future buyers, contractors, insurers, or agencies may ask for it.

What can delay or complicate approval

Many Section 26a delays come from preventable problems. The most common are incomplete applications, unclear drawings, and projects that do not fit site conditions.

Other issues that can slow review include:

• Disputes over property lines or access rights

• Existing unpermitted structures

• Work proposed on TVA public land

• Narrow coves or navigation conflicts

• Wetlands or sensitive habitat nearby

• Major dredging or fill

• Projects that affect neighboring properties

• Construction started before approval

• Missing state, local, or federal permits

  
  

A contractor who works often on TVA lakes can help, but the property owner should still understand the permit requirements. The permit responsibility does not disappear just because someone else is hired to build the project.

Tips for a smoother application

A good application answers TVA’s likely questions before they are asked.

Use these practical steps:

• Start early

  
  

Apply before ordering materials or scheduling crews.

• Match the project to the site

  
  

A dock that works in a wide, deep embayment may not work in a narrow cove.

• Be accurate

  
  

Guessing at measurements can cause redesigns later.

• Show existing conditions

  
  

Include photos of erosion, old structures, vegetation, and nearby docks.

• Keep neighbors in mind

  
  

Avoid designs that block access, crowd property lines, or create navigation conflicts.

• Do not clear first

  
  

Wait before removing vegetation or disturbing soil near the shoreline.

• Save every approval

  
  

Keep permits, drawings, and correspondence in one file.

If you are purchasing lakefront property, ask for copies of existing TVA approvals during due diligence. A beautiful dock is less appealing if no one can prove it was permitted.

A properly permitted shoreline project protects property use and lake access.

After the permit is approved

Approval is not the final step. The project still needs to be built according to the approved plans and permit conditions.

Before construction starts, share the permit with your contractor and review:

• Approved dimensions

• Allowed materials

• Work limits

• Erosion control requirements

• Equipment access routes

• Any timing restrictions

• Any required inspections or notices

  
  

If field conditions require a change, contact TVA before making that change. Even small adjustments can matter if they move the structure, increase the footprint, or affect the shoreline.

Once the work is complete, keep photos and receipts with your permit file. These records can help if questions come up later.

The main takeaway

Section 26a permitting is part of responsible lakefront ownership on TVA-managed waters. It protects the reservoir system while giving property owners a clear path to improve access, stabilize shorelines, and maintain safe structures.

The best approach is simple: ask early, document clearly, apply before work begins, and wait for written approval.

A well-prepared application can save weeks of back-and-forth and help make sure your local lake project is built legally, safely, and with fewer surprises.
