Decks, Docks And Permits On The Tennessee River

November 6, 2025

Thinking about adding a dock or stabilizing your shoreline on the Tennessee River in Lookout Valley? It’s exciting to picture morning coffee on a riverside deck or a quick launch for an afternoon paddle. It’s also normal to feel unsure about permits, timelines, and who approves what before you start.

This guide walks you through when TVA Section 26a and other permits apply, how shoreline rules shape your design, and what a realistic approval timeline looks like in Chattanooga’s Lookout Valley. You’ll also get a simple checklist to keep your project on track. Let’s dive in.

Who regulates the Tennessee River shoreline

TVA: Section 26a and shoreline management

The Tennessee Valley Authority oversees most work within the TVA project boundary, which includes the reservoir shoreline and the land right next to it. If your project involves a dock, pier, boat lift, bulkhead, riprap, bank grading, boat ramp, or clearing vegetation within that boundary, you likely need TVA Section 26a consent. TVA also uses a Shoreline Management Program that classifies shoreline segments and limits certain uses based on that classification.

TVA’s review looks at navigation safety, reservoir operations, environmental and cultural resources, and the overall public interest. Your shoreline’s classification will guide allowed structure sizes, setbacks, and whether fees or mitigation apply.

U.S. Army Corps of Engineers: Sections 10 and 404

Because the Tennessee River is a navigable waterway, work that affects navigation can trigger a permit from the U.S. Army Corps of Engineers. If your project involves dredging or filling within waters of the U.S., Clean Water Act Section 404 may also apply. Some projects qualify for general or nationwide permits, while others need individual review.

Tennessee state regulators: TDEC ARAP

The Tennessee Department of Environment and Conservation oversees the Aquatic Resource Alteration Permit program. If your shoreline plan alters a stream, bank, or wetland, you may need an ARAP. This often comes up with stabilization, channel work, or any fill below the ordinary high-water mark.

Local government: City of Chattanooga or Hamilton County

Local building, zoning, stormwater, erosion control, and land-disturbance permits often apply before construction starts. Lookout Valley properties can sit inside Chattanooga city limits or in unincorporated Hamilton County. Confirm your parcel’s jurisdiction because processes and forms differ.

How agencies coordinate

Many projects require approvals from more than one agency. A typical path for a Lookout Valley dock or stabilization includes TVA 26a plus USACE and TDEC. Agencies may condition approvals on each other, and you may see environmental or cultural resource coordination across them. Planning for multi-agency review is part of a realistic timeline.

What work needs a permit in Lookout Valley

In general, expect permits if you plan to:

  • Build, replace, or significantly modify a dock, pier, or boat lift.
  • Install a deck over water or extend any structure into the project boundary.
  • Stabilize the shoreline with riprap, bulkheads, retaining walls, seawalls, or gabions.
  • Grade, excavate, or place fill along the bank.
  • Construct a boat ramp or launch.
  • Run utilities, poles, or other structures in the shoreline area.
  • Remove trees, clear vegetation, or grade within the TVA project boundary.
  • Use temporary construction access in or across the water.
  • Dredge or remove vegetation in wetlands or watercourses.

Repairs to existing structures can be tricky. Some limited maintenance may proceed without full permitting, but many repairs and all substantial modifications require review. Do not assume a dock or wall is grandfathered. Before demolition, check for TVA consent and local records, especially if the structure predates modern rules.

How shoreline rules shape your design

Shoreline classification matters

TVA’s Shoreline Management Program classifies shoreline segments. That classification helps define what types of structures are allowed, where you can place them, and how large they can be. It may also affect fees or mitigation.

Stabilization preferences

Regulators favor softer, bioengineered stabilization where it can work. Plantings, coir logs, and reshaped banks with native vegetation reduce impacts. Hard armor like bulkheads and seawalls is common in some stretches, but it typically needs engineered plans showing stability and minimal harm to the riverbank and habitat.

Navigation and pool fluctuations

Designs must keep navigation lanes safe and account for TVA reservoir operations and seasonal water level changes. Floating docks suit fluctuating pools but need secure anchoring. Fixed pile docks may be appropriate in shallower areas, but piles must be engineered for changing water levels.

Cumulative and neighborhood context

TVA considers how your project fits along the shoreline. Multiple docks in close proximity can narrow navigation or limit bank access. Your plan should address setbacks from property lines and clearances from nearby docks to avoid conflicts.

Access and aesthetics

Local rules or recorded easements can affect siting. Your deed, HOA covenants, or riparian rights may define where and how you can build. Confirm these early to avoid redesigns.

What to include in your application package

A complete, high-quality package speeds review. Common items include:

  • Completed TVA Section 26a application.
  • Scaled site plan showing property lines, existing structures, proposed footprint, shoreline orientation, normal pool elevation, and distances to adjacent docks.
  • Cross-sections and construction drawings with dimensions, materials, anchoring, and elevations relative to normal pool.
  • A recent survey showing property boundaries, normal and high-water marks, and topography.
  • Photos from multiple angles, including upstream and downstream context.
  • A narrative describing construction sequence, access routes, timing, erosion and sediment control, and restoration measures.
  • Engineered design and calculations for hard stabilization like retaining walls or riprap, plus erosion control plans.
  • Contractor qualifications or proof of a licensed marine contractor if required.
  • Environmental documentation if needed, such as wetlands delineations or cultural resource clearance.
  • Proof of ownership and any recorded easements or rights.
  • Payment of application or processing fees where applicable.

For U.S. Army Corps of Engineers and TDEC:

  • The Corps often requires wetlands delineations, impact avoidance and minimization, and mitigation plans if impacts are unavoidable.
  • TDEC ARAP expects detailed alteration plans, Best Management Practices for erosion control, and sometimes monitoring plans.

How long approval takes

Timelines vary by project scope, site conditions, and agency workload. Typical ranges include:

  • Simple residential floating dock or modest replacement with a complete application: about 30 to 90 days for TVA if no other permits are needed.
  • New docks with engineering details or stabilization with limited environmental issues: about 60 to 180 days, allowing time for USACE and TDEC coordination if required.
  • Complex projects with bulkheads, major bank regrading, dredging, wetlands, cultural resources, or individual USACE permits: about 6 to 12 months or more.

What speeds things up:

  • A pre-application conversation with TVA and early outreach to USACE and TDEC.
  • Standard designs that fit common approvals.
  • Complete, clear plans, cross-sections, surveys, and erosion control details.
  • Hiring engineers and contractors who know TVA, USACE, and TDEC processes.
  • Avoiding disturbance of wetlands and native vegetation where possible.

What can slow reviews:

  • Incomplete applications or missing drawings and surveys.
  • Public notice periods for the Corps, which can add 30 to 90 days.
  • Flags for wetlands, endangered species, or archaeology, which require more studies.
  • Neighbor objections or design conflicts with navigation or setbacks.
  • Seasonal or staff-related agency slowdowns.

Emergency work for imminent risks can get expedited attention, but you still need to notify agencies right away and follow up with a permit application. Confirm what is allowed before starting anything beyond temporary safety measures.

Step-by-step for Lookout Valley homeowners

Follow this process before demolishing or building:

  1. Confirm location against the TVA project boundary and normal pool. Ask TVA Shoreline Management for your property’s shoreline map or confirmation.

  2. Request a pre-application review with TVA Section 26a. Ask about your shoreline classification and any known constraints.

  3. Contact the U.S. Army Corps of Engineers and TDEC if you plan dredging, fill, or work affecting streams or wetlands. Clarify whether general or individual permits apply.

  4. Verify local jurisdiction. Check whether your parcel is inside Chattanooga city limits or in unincorporated Hamilton County. Contact City of Chattanooga Development Services or Hamilton County Building and Codes about building, stormwater, erosion control, and land-disturbance permits.

  5. Build the right team. Hire a licensed engineer for hard stabilization, a surveyor for property and water elevations, and a marine contractor with TVA experience.

  6. Prepare a complete application package. Include site and cross-section plans, photos, erosion control measures, contractor info, and fee payments.

  7. Coordinate submittals and responses. File with all relevant agencies, track requests for more information, and schedule inspections as needed. Keep detailed records of communications.

  8. Wait for all approvals before work. Keep copies of TVA 26a consent and any USACE, TDEC, and local permits on site during construction.

Risks of starting without permits

Starting shoreline work without the right approvals can lead to stop-work orders, penalties, and orders to remove or fix unpermitted work. That can add months and significant costs to a project. Deed restrictions, HOA rules, and riparian easements also carry weight. Check title documents early to avoid surprises.
