Lake Austin drawdown 2026: dock and bulkhead repair permits

Short answer

During the Lake Austin drawdown (October 12 to November 30, 2026) the lakebed is exposed so owners can repair shoreline structures, clear sediment from boat slips, remove debris, and manage nuisance vegetation. For minor dock and bulkhead repairs, the city created an accelerated 2026 Lake Austin Drawdown Site Plan Exemption Request form, and it will not be accepted after November 2026 - submit early enough for review and for the work to finish. What you need depends on the work: painting, staining, furniture, and limited lighting need no permit; simple re-decking, repairs to an existing structure, and bulkhead repairs up to 25% (with no site-plan-free repair in the previous three years) need a site plan exemption plus a building permit; new construction, footprint expansions, load-bearing replacements, and demolition need a full site plan permit. Removing sediment for navigation is allowed under the exemption during the 2026 drawdown only. Nuisance vegetation removal needs a separate Texas Parks and Wildlife permit. Work can begin once the lakebed is exposed and your permit is approved. Questions go to siteplancommunications@austintexas.gov or 512-978-4691.

Who this is for

Lake Austin, Lady Bird Lake, and Lake Walter E. Long shoreline owners planning dock, bulkhead, or boat-slip work.

The steps, in order

1. Classify the work: no permit (paint, stain, furniture, limited lighting), site plan exemption (re-decking, like-for-like repairs, bulkhead repairs up to 25%), or full site plan permit (new construction, expansions, load-bearing replacements, demolition).
2. For minor dock and bulkhead repairs during the drawdown, use the special 2026 Lake Austin Drawdown Site Plan Exemption Request (PDF) for accelerated review.
3. Submit well before the end of November 2026 - the special form is not accepted after November, and review plus construction must fit the drawdown window.
4. Pull the building (or demolition) permit that pairs with the exemption or site plan before starting.
5. Removing nuisance vegetation? Get the Texas Parks and Wildlife Department permit first.
6. Start work only once the lakebed is exposed and permits are approved; the window closes November 30, 2026.
7. After building or rebuilding, register the dock with the city so public safety crews can see it.

Have this ready

• The property's shoreline address and dock details
• Photos and a description of the repair scope
• The 2026 drawdown exemption form for minor repairs
• A building permit application that pairs with the exemption
• TPWD permit if removing nuisance vegetation

Common mistakes to avoid

• Missing the November 2026 cutoff for the accelerated exemption form - regular review timelines apply after.
• Starting before the lakebed is exposed or before permits are approved. Both conditions must hold.
• Repairing more than 25% of a bulkhead under the exemption, or repeating exemption repairs within three years - that pushes the job into a full site plan.
• Assuming sediment removal is always exempt. The exemption covers it for navigational access during the 2026 drawdown only.
• Forgetting dock registration after construction; it is required for public-safety visibility and addressing.
