The neck of land between I-35E and open water, from the mouth of the Hickory Creek arm up to the toll bridge landing. This is the city that gave the reservoir its old name — and Shoretech is currently the only contractor the Corps permits to reinforce shoreline anywhere on it.
Bulkheads on Lewisville Lake had been built for years by people who did not know how to build them. Walls leaned, backfill washed out, and sections ended up in the water. The Corps of Engineers stopped permitting shoreline reinforcement on the lake entirely.
A property owner pushed for an exception and brought Shoretech to the table. Permitting that single job took a year — design submitted, reviewed, wall built, wall inspected. On the strength of that inspection the Corps authorized one contractor instead of reopening the lake, and that authorization stands through the end of December 2027, renewable.
For a Lake Dallas owner watching a bank retreat, that is the whole practical picture: a wall is possible again, the route to it is narrow, and the calendar is stated.
Engineered reinforcement at the water line, with embedment, tiebacks, drainage and backfill sized to the reservoir's operating range. This is the authorized work, and it is submitted as a design the Corps reviews — which is how the authorization was earned in the first place.
Slope stabilization and erosion control on ground you genuinely own, uphill of the Corps boundary. Ordinary private construction, no federal permit — and frequently the correct answer on the bluffs and points along Lakeview and Lakebluff.
Repair and restoration of a boathouse that already carries a shoreline use permit — substructure, decking, roof, lift, electrical — kept to what the Lake Office will approve for that structure, where it already stands.
Straight across is Little Elm. There is nothing between you and it.
Lake Dallas holds the west shore of the main body of Lewisville Lake. Its eastern edge is not a straight bank but a scallop of points and pocket coves: Willow Grove point at the southeast tip, the ridge that North and South Lakeview Drive ride, the cove at the end of Marina Drive, and the Montserrat shore at the north end. At 2.75 square miles of city with about a third of a square mile of water, this is the wateriest of the Lake Cities.
That eastward aspect is the thing that separates a Lake Dallas bank from a bank inside the Hickory Creek arm a mile to the south. Nothing interrupts the water in front of you until Little Elm and The Colony, and the main navigation channel, the marina traffic and the toll-bridge crossing all put boat wake on this shore on top of whatever the wind does with that open reach. No fetch or wave study has been published for this reservoir, so nobody can quote you a design wave — but the geometry is on the map and it is not subtle.
The name is older than the lake you see. The 1927 Garza Dam reservoir on Hickory Creek was Lake Dallas, and it supplied the City of Dallas for thirty-one years until the Corps' Lewisville Dam drowned it in 1955; Garza Dam was breached in 1957 and its site is under this water. A bridge once ran across to Little Elm and was removed when the lake was enlarged — the Lewisville Lake Toll Bridge, 1.7 miles, opened 1 August 2009, restored that link after half a century off the city's north side.
The city's own plan names its districts Main, Shady Shores, Lakeview, Swisher, Marina and Hundley — and its zoning code carries an MA, Marina District. This is a town that organises itself around the shoreline.
Willow Grove is the city's biggest park, leased from the Corps of Engineers, with a beach, fishing pier, a one-lane ramp and dock, camping and a shoreline trail through the trees — and it hosts WaterFest in September and the Lake Cities Fourth of July. Lakeview Marina at 300 Marina Drive has been run by the Drozd family since 1942, when it started as a fishing camp; it is the oldest continuously operating business in town.
Shoreline reinforcement first, because it is the one thing on this lake Shoretech alone is currently permitted to build. New docks and new boathouses are not offered, because the Corps is not permitting them here for anyone.
The authorized work, and the only route to a new wall on this lake while the authorization stands. Designed to the reservoir's spread rather than to the water level on the day of the visit.
Bank stabilization on private ground above the federal boundary — steel, vinyl, FRP composite or heavy timber, chosen for the soil and the exposure rather than for the catalogue.
Restoring a structure that came with the house and already carries its permit — substructure, decking, roof, lift, lighting — without changing where it sits or what it is.
Slips, gangways, breakwaters and pile work for operators and municipalities holding their own agreement with the Corps, on a shore that keeps a working marina and a leased city park.
Post-war cabins, teardown-and-rebuild customs on the good points, and waterfront condominium product — sometimes on the same block.
This is the oldest lake housing of the Lake Cities and the most mixed. The Lakeview Drive, Lake Drive and Shore Drive side still carries 1960s and 70s lake lots; there are manufactured-home communities, including Lake Haven Estates; there are customs replacing cabins on the points; and there is townhome-style waterfront product like Water's Edge. The city's comprehensive plan calls out improvement to those older neighborhoods near the lake and designates a waterfront mixed-use category near the existing marina — meaning the lakefront here is treated as a redevelopment target rather than a finished product.
What that means for a wall: the ground is often being asked to do something new. A bank that held up a cabin and a set of wooden steps for fifty years is now behind a house with a bigger footprint, more roof, more hardscape and more concentrated runoff — with Corps fee land and flowage easement to 537 feet sitting between the lot and the waterline. The 2018 comprehensive plan notes that the parts of the city near the lake and its feeder creeks sit in floodplain.
Nobody has published an erosion or shoreline-retreat study for Lake Dallas, and the city's plan does not name erosion as an issue. Shoretech will not invent one. What can be stated is the record: the lake peaked at 536.95 feet msl on 31 May 2015, roughly fifteen feet above conservation pool and effectively at the top of the flowage easement. A wall designed for a calm 522-foot afternoon is a wall designed for a lake that does not exist.
Currently, yes, and currently only through Shoretech. The Corps of Engineers had closed Lewisville Lake to new shoreline reinforcement after a run of failed walls. Instead of reopening it to every contractor, they authorized a single one, working to a design they had already reviewed on a wall they had already inspected — an authorization that runs through the end of December 2027 and is renewable. The other half of the answer is where the federal line falls on your lot. Corps fee land and flowage easement to 537 feet msl sit between most private lots here and the waterline, so whether the failing ground is yours or the Government's decides whether you are looking at a bulkhead or a retaining wall.
Ten miles south, on the same reservoir, it already has. The City of Lewisville commissioned a Lake Park master plan with Halff Associates covering roughly two miles of shoreline where erosion was running faster than anticipated, did emergency repairs at two locations that were threatening trails and a pavilion, and is now pursuing permanent erosion control with elevated piers and boardwalks instead of restoring the swim beach. Council approved Phase 1 engineering in June 2024. That is the City of Lewisville, not Lake Dallas — but it is the same water, the same pool operation and the same soils, and the numbers are public.
No. The Corps is not allowing construction of new boat houses or docks at Lewisville Lake, and the bulkhead authorization did nothing to change that — they were two separate decisions and only one went our way. The only route to a private structure here is buying a property that already carries a permitted one. That shoreline use permit runs five years, currently costs $35, is not transferable, and cannot be relocated from where the structure already stands.
It is a real constraint and it belongs in the conversation early rather than on the first morning of work. The older neighbourhoods east of the rail line are narrow, gridded and largely without sidewalks, and they fall toward the water, so working room at the bank is tight and staging usually happens on the street. The city's own comprehensive plan flags those streets for repaving and sidewalk work. Dave will walk the approach before anything is designed, because the wall that can actually be built is the wall the equipment can reach.
Tell Dave where the concrete monuments fall on your lot, what the bank has done in the last two high years, and how a truck gets down your street. Permitting on this lake took a year the first time, so the useful move is a conversation now rather than one against the calendar.
