Old Hickory Lake Dock Permits: USACE Nashville District

Who Issues Dock Permits on Old Hickory Lake

The U.S. Army Corps of Engineers Nashville District issues dock permits and regulates shoreline use on Old Hickory Lake. This is the foundational fact that most online research about Tennessee lake dock permits gets wrong, because the majority of Tennessee's large reservoirs are managed by TVA — and TVA's Shoreline Management Policy, permit applications, and fee structures are well-documented and widely circulated online. Old Hickory Lake is not a TVA lake. TVA has no jurisdiction here. Using TVA's forms, calling TVA's shoreline management number, or designing a dock to TVA's specifications is the wrong process for Old Hickory.

The correct contact is the USACE Nashville District Regulatory Division: 615-736-7161. The regulatory framework is CFR Title 36, Part 327 for general conduct on Corps properties, and Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899 for permits involving work in or adjacent to navigable waters. For most private residential docks on Old Hickory Lake, the permit pathway is either an Individual Permit (for larger or more complex structures requiring case-by-case review) or a Nationwide Permit under NWP-1 (for structures that meet the standard criteria and qualify for the expedited nationwide permit process). Your dock builder and a consulting engineer familiar with USACE Nashville District processes can advise on which pathway applies to your specific project.

Timeline: 45–90 Days Is Not a Guideline

USACE Individual Permit review at Nashville District typically takes 45–90 days from receipt of a complete application. This is not TVA's process, which for many standard dock applications can move faster. It is not Santee Cooper's process at Lake Marion, which has a shorter review once the application is complete. Plan for a full 90 days from submission to permit issuance for an Individual Permit at Old Hickory Lake. If you are purchasing a property intending to build or substantially modify a dock, factor this timeline into your planning. Applications submitted in October for spring construction may be fine — applications submitted in March for May construction may not be. Start the permitting process early, and note that concurrent TDEC ARAP review, which often accompanies USACE permit applications for dock construction in Tennessee, adds another process layer to manage in parallel.

The New Shoreline Management Plan: Why Specifications Are in Flux

USACE Nashville District held two public input workshops for the Old Hickory Lake Shoreline Management Plan update on January 13, 2026, in Mt. Juliet and January 14, 2026, in Gallatin. A Shoreline Management Plan governs how the shoreline can be used — what dock types and sizes are permissible in which zones, what vegetation clearing is allowed, which shoreline segments are open for private use and which are restricted, and other operational parameters. The current plan was last significantly updated in 2020. The workshops were the public input phase for a revision. When the new plan is finalized, it will update the specific construction standards, permitted uses, and zone designations that apply to dock permits and shoreline projects on Old Hickory Lake.

For buyers planning dock construction or major shoreline modifications, the SMP update matters for two reasons. First, any permit application submitted before the new plan is finalized will be reviewed under the current specifications — but if construction does not start before the new plan takes effect, any variances from the new standards may require modification. Second, the new plan's zone designations may affect whether a specific property remains in an "open" zone (eligible for private dock permits) or is reclassified. The SMP update process typically takes months from the workshop stage to final publication. Contact USACE Nashville District at 615-736-7161 for the current status of the plan update and the timeline for finalization before committing to a dock project.

Houseboats: Not Permitted on Old Hickory Lake

USACE Nashville District does not permit houseboats as private dockside structures on Old Hickory Lake. This contrasts with Percy Priest Lake (also USACE Nashville) which has historically had houseboats permitted, and with some TVA lakes where houseboats are a recognized use. On Old Hickory, if you want to live on the water in a floating structure, this is not the lake for it. Standard residential docks, covered boat slips, wave-runner lifts, and standard floating dock configurations are permitted subject to the SMP specifications. Houseboats as permanent or long-term dockside residences are not.

Dock Eligibility: Not Every Lot Qualifies

Many waterfront properties on Old Hickory Lake have private docks that have been individually permitted by USACE Nashville District. But not all lakefront lots are eligible for dock permits. Eligibility depends on the shoreline zoning designation in the Shoreline Management Plan, the distance from adjacent dock structures (spacing requirements), water depth at the proposed dock location, environmental considerations specific to the site, and whether the property boundary adjoins Corps-managed land in a way that requires a permit versus privately deeded shoreline. Agents and sellers sometimes describe a property as "dock eligible" based on the presence of a dock on an adjacent property, which is not a reliable indicator. Before making an offer on any Old Hickory Lake property without an existing dock, contact USACE Nashville District to confirm whether the specific lot is eligible for a dock permit under the current Shoreline Management Plan.

Existing Dock Due Diligence

For properties with existing docks: request the current USACE permit number and confirmation it is active and valid. Confirm the permit is in the seller's name and covers the current dock configuration — any modifications made without a permit amendment are a compliance issue that will need to be addressed. On sale, the dock permit does not automatically transfer; the new owner typically needs to notify the Corps of the ownership change and update the permit records. Contact USACE Nashville District Regulatory at 615-736-7161 for the current process for updating permit records after a property sale. Begin this process promptly after closing — do not wait months to notify the Corps of the change in ownership.

TDEC ARAP: The Second Permit Often Required

In Tennessee, construction in or adjacent to the waters of the state may require an Aquatic Resource Alteration Permit (ARAP) from the Tennessee Department of Environment and Conservation Division of Water Resources. TDEC ARAP review is often concurrent with USACE permit review for dock construction projects. For some Nationwide Permits, TDEC pre-certification may apply, simplifying the process. For Individual Permits, a separate TDEC application and review is typically required. Your dock builder or project engineer should be familiar with coordinating USACE and TDEC review processes for Middle Tennessee lake projects — ask specifically about their experience with both agencies on Old Hickory Lake before hiring.
