Custom Boat Dock Construction — Lake Travis, Lake Austin & Highland Lakes

Every dock we build is permitted through LCRA before the first board goes in. We've pulled hundreds of LCRA permits across the Highland Lakes — we know what gets approved, what gets flagged, and how to engineer around the edge cases.

ATX Lakescapes is a licensed and insured marine contractor based in Leander, Travis County. We've been designing and building custom docks across Lake Travis, Lake Austin, Lake LBJ, Lake Marble Falls, Lake Buchanan, Inks Lake, and Canyon Lake for twelve years. The first dock we built is still on the water. The most recent dock we built passed final inspection last week. The work in between has been a long, deliberate lesson in what survives on the Highland Lakes and what doesn't.

Most homeowners who call are deciding between three things: a new custom dock on a raw shoreline, a teardown and rebuild on an aging structure, or an addition to an existing permitted footprint — a second slip, a swim platform, a covered roof, a party deck. The right answer almost always depends on the lake, the cove, and the LCRA permit history of the property. That's why the first step is always a free on-site visit and a permit-history pull before we put a number on paper. We don't compete on price; we compete on getting the right dock built for the property the first time.

Custom Dock Design & Construction

Every dock is designed around the property and the homeowner, not the other way around. The design phase starts with a site visit, a shoreline survey, a permit-history pull on the property, and a conversation about how the dock will actually be used — number of boats, type of boats, swim and lounge use, covered slip preference, lift integration, electrical, lighting, and storage.

From that we draft a concept, refine it against the LCRA envelope for the specific cove, and produce engineered drawings stamped by a Texas Professional Engineer. The same drawing set we submit to LCRA is the drawing set we build from — no value-engineering surprises on installation day, no contractor shortcuts that show up two years later as a sagging frame.

Dock Types We Build

Fixed docks are the standard on Lake Austin and on Highland Lakes coves where the water elevation is stable. Fixed docks support second-story decks, taller covered roofs, broader overhangs, and design features that simply don't work on a floating platform.

Floating docks dominate Lake Travis because the lake moves vertically far too much for a fixed structure to remain functional. Modern floating docks on the Highland Lakes use aluminum framing, HDPE flotation, composite decking, and articulated ramp systems engineered to track the LCRA operating range from full pool to drought minimum.

Covered slip docks protect the boat and the lift from sun and weather. We build covered slips with shingled roofs, standing-seam metal roofs, and full hip-roof structures with tongue-and-groove ceilings. Roof style is largely a function of HOA architectural rules and the homeowner's house — we match.

Multi-slip docks serve households with more than one boat, a PWC fleet, or family compounds with multiple boats coming and going. Two-slip and three-slip docks are routine; we've built four-slip docks where the LCRA envelope and the cove geometry support them.

Party-deck docks add a large open deck, often with shade structures, bar areas, and lounge zones, on top of or adjacent to the slip footprint. These are the largest builds we do and the most rewarding — they turn the dock from a parking spot for the boat into the family's primary outdoor room from May through October.

LCRA Permitting

LCRA is the permitting authority for private docks on Lake Travis, Lake Austin, Lake LBJ, Lake Marble Falls, Lake Buchanan, and Inks Lake. The permit process covers the dock envelope (the maximum footprint the dock can occupy on the shoreline), materials, electrical, lighting, lift integration, and any modifications to the shoreline itself. The permit also requires HOA architectural sign-off in most lakefront subdivisions and neighbor notification in many coves.

We are the LCRA permit applicant of record on every dock we build. Homeowners do not file paperwork, do not field requests for additional engineering details, and do not deal with the permit reviewers directly. Our typical permit timeline runs 8 to 14 weeks on Lake Travis and Lake Austin, faster on the upstream lakes where cove pressure is lower. The full permitting workflow is documented on the site.

Design-Build Process

We deliver as a single contract: design, engineering, permit, materials, build, lift integration, electrical, commissioning, and warranty. That model exists because the alternative — homeowner coordinates a designer, an engineer, a permit consultant, a builder, an electrician, and a lift installer — produces gaps that show up later as missing details, mis-coordinated lift placement, or revisions that LCRA flags after the materials are already on the water.

Five phases:

1. Consultation and concept. Free on-site visit, shoreline survey, permit-history pull, design concept, written proposal with a fixed fee. Two to four weeks.

2. Engineering and permit. Stamped engineered drawings, LCRA submission, HOA review, neighbor notifications, permit issuance. 8 to 14 weeks.

3. Material staging. Aluminum framing, flotation, decking, roof system, electrical, and lift components ordered, received, and staged. Runs in parallel with the back half of permit. 4 to 8 weeks.

4. On-water construction. Frame assembly, decking, roof, electrical, lift integration. Barge-based on tight coves, launch-staged on open coves. 4 to 8 weeks.

5. Commissioning. Lift sizing verification, electrical sign-off, walkthrough with the homeowner, warranty registration, and enrollment in our maintenance program if the homeowner wants it. One to two weeks.

Materials & Engineering

Framing is marine-grade aluminum on almost every build — corrosion-resistant, lighter than steel, and dimensionally stable through the temperature swings the Highland Lakes see. Flotation is encapsulated HDPE — closed-cell, UV-resistant, and warranted for 20+ years. Decking is composite (Trex, TimberTech, MoistureShield) for the long-warranty applications and Garapa or ipe hardwood for the homeowners who want the natural look and will accept the higher maintenance.

Hardware is stainless steel or hot-dip galvanized — never plain steel. Electrical is GFCI-protected, marine-rated, and pulled in continuous cable runs with no underwater junctions. Anchoring uses helical screw anchors on most Lake Travis coves, dock-piling integration on Lake Austin fixed docks, and cove-specific systems on the upstream lakes. Every choice is documented in the engineered drawing set.

Dock Construction for Highland Lakes Water Level Fluctuation

Lake Travis has swung more than 60 vertical feet over the past decade. Lake Buchanan and Inks Lake move similarly when the system is in drought. A dock engineered for the average year fails the first time the lake moves to an extreme. A dock engineered for the LCRA operating range — full pool to drought minimum — performs through every cycle.

That means floating frames sized for storm-load and drawdown-load, not just calm-water-load. Articulated ramps long enough to remain functional at low pool and properly anchored above water at high pool. Guide pilings driven to engaged depth at drought minimum. Electrical and water service designed with enough vertical travel to follow the dock without binding. None of this is glamorous and none of it shows in a photograph. All of it is the difference between a fifteen-year dock and a five-year dock.

Service Area

We design and build custom docks across the full Highland Lakes chain — Lake Travis, Lake Austin, Lake LBJ, Lake Marble Falls, Lake Buchanan, Inks Lake — and Canyon Lake. From our Leander, Travis County base we run Lake Travis and Lake Austin daily and mobilize to the upstream lakes weekly. Estimates, site visits, and permit-history pulls are free and never billed back. We're a local crew that has been on this water for twelve years.
