Long Beach Retaining Wall Contractors
Perched on the Lake Michigan dune bluffs of LaPorte County, Long Beach poses a retaining-wall problem most inland towns never face: steep, sandy grade changes that have to be held in place season after season. Shore Protect Construction brings 20+ years of installation, repair, and replacement work to residential and commercial lots from the Long Beach lakefront through Duneland Beach and Sheridan Beach. We design drainage-first wall systems for backyard slopes, driveway cuts, pool-deck retention, terraced gardens, and stabilization near Burns Waterway and Trail Creek β all built for wind-deposited dune sand that drains fast in summer and heaves hard under winter frost. the Long Beach Building Department permits and county drainage easement coordination handled.
Services: repair, full replacement, or new installation depending on wall condition, height, and surcharge load.
Materials: pressure-treated timber, segmental and poured concrete, natural stone, brick, gabion baskets, galvanized metal, composite block, and rip-rap scrim-bag systems selected by wall height, drainage, and soil conditions.
Local expertise: tuned to Long Beach's lake-border dune sand, the wind-deposited dune sand and lacustrine silt below it, lake-effect rainfall and hydrostatic load, the Long Beach Building Department permit thresholds, and county drainage easement requirements.
Long Beach retaining walls start at $15/SF (timber, residential under 4 ft) to $70/SF (brick / specialty stone) installed. See full pricing breakdown →
Long Beach retaining wall contractors: Installation, repair, and replacement for homes and businesses. Built for lake-border dune sand subgrade, lake-effect rainfall hydrostatic load, and surcharge from driveways or pool decks.
Lots along the Long Beach lakefront ride out concentrated frost-heave and saturation cycles, hydrostatic pressure from roughly 38 inches of annual precipitation plus lake-effect snow, with deep winter frost and freezeβthaw cycles, and surcharge load from driveways, pool decks.
Dune sand and lacustrine silt subgrade lifts with winter frost and loses bearing strength when it saturates; heavy lake-effect rainfall stacks hydrostatic pressure against the wallβ precisely where unprotected bluff yards shed slope, faces bow, and caps split.
The lake-effect rainy season drives wave after wave of downpours off Lake Michigan, soaking dune-sand backfill and loading the back face of any wall built without engineered drainage β far and away the leading cause of premature retaining wall failure across LaPorte County.
Anything over 4 feet, any surcharge-loaded wall, and any wall inside an county drainage easement footprint calls for permits, sealed engineering, and easement review before a shovel hits the dune sand.
A Long Beach lot demands more than a stacked-block weekend projectβ lake-border dune sand frost heave and saturation, hydrostatic pressure off the lake-effect rains, surcharge load from driveways and pool decks, and the Long Beach Building Department / county drainage permit requirements each dictate how a retaining wall has to be designed to hold for the long term.
Most Long Beach homes and businesses sit on the lake-border dune sand formation, with wind-deposited dune sand and lacustrine silt filling the active zone over a seasonally high water table. These frost-susceptible soils heave under winter frost and shed bearing strength the moment they saturate, producing repeated seasonal ground movement. Where a stable inland site stays put, the Long Beach subgrade shifts with every freeze-thaw and wet-dry swing, cracking caps, bowing wall faces, and rotating deadman tie-backs loose in waterlogged backfill. A retaining wall on this dune sand has to carry its footing below the most active frost zone into stable strata, lean on geogrid reinforcement on tall walls (mechanically stabilized earth construction), and route water away with engineered drainage to head off the seasonal saturation that drives most failures.
Long Beach takes in about 38 inches of precipitation a year, much of it in concentrated lake-effect storm cells that flood the soil profile in hours rather than days. That water piles up behind any retaining wall lacking weep holes, a gravel chimney drain, and a perforated PVC footing drain β converting what ought to be a static earth-load problem into a combined earth-plus-water load that an un-drained wall simply cannot hold. The record 2019β2020 Lake Michigan high-water years and severe lakefront storm seasons left a trail of failed walls across LaPorte County backyards. Lots backing onto Burns Waterway, Trail Creek, or the Grand Calumet River take on extra scour at the wall toe when flows run high. A Long Beach wall has to be sized for both the everyday rainfall climate and the design saturated-soil event particular to its site.
The the Long Beach Building Department Engineering Branch reviews retaining wall building permits for walls over 4 feet tall measured from the bottom of the footing, and any wall carrying a surcharge β driveway, pool, structure, or sloped backfill β typically needs sealed engineering drawings no matter its height. Walls falling within an the County Surveyor's office (regulated drains under IC 36-9-27) drainage easement along Burns Waterway, Trail Creek, or the Grand Calumet River trigger county drainage review and may be off-limits inside the easement footprint entirely. HOA design review is the norm in the Long Beach lakefront and Duneland Beach. Opening the permit conversation before the excavator arrives is what spares Long Beach projects the redesigns and stop-work orders that bog down so many of them.
A failing retaining wall eats into usable yard, leaves upland improvements (foundations, patios, pool decks) open to slope creep, and compounds structural trouble with every wet season. Locking the slope down with a properly engineered wall protects both property value and long-term site usability β no small thing in Long Beach's premium dune-bluff submarkets like the Long Beach lakefront and Duneland Beach, where mature trees and steep split-level lots make grade retention non-negotiable.
Key Takeaway: In Long Beach, a wall that ignores lake-border dune sand frost heave, lake-effect rainfall hydrostatic pressure, surcharge load from above, or the Long Beach Building Department permit requirements will cost far more to repair or replace than one engineered right the first time.
Picking the right material for a Long Beach lot starts with wall height, surcharge load, drainage demands, and target lifespan β then weighs treated timber, segmental block, poured concrete, stone, brick, gabion, metal, or composite against the dune-sand realities of the site.
The go-to for walls over 4 feet, driveway cuts, pool-deck retention, and surcharge-loaded sites, where a 40β75+ year design life and engineered MSE (mechanically stabilized earth) construction earn back the higher upfront cost.
The budget pick for short backyard grade walls under 4 feet with no surcharge β driveway cuts, pool-deck retention, and any tall wall under permit need a heavier material instead.
Wire-cage and stone systems shine on drainage-adjacent lots near Burns Waterway or Trail Creek where free drainage is a feature rather than a foe, and on the irregular dune slopes where a vertical wall isn't called for.
How long a Long Beach wall lasts comes down to how well the build reckons with lake-border dune sand frost heave, hydrostatic pressure from lake-effect rainfall, surcharge loading from above, and the particular quirks each material brings to dune-sand ground.
Footings on Long Beach residential walls usually run 2β4 feet below grade to seat below the most active frost zone and into stable strata; tall and surcharge-loaded walls under permit reach deeper per the geotech recommendation. A continuous footing of compacted #57 gravel or poured concrete spreads wall load across the loose lake-border dune sand subgrade and holds off the differential settlement that seasonal frost-heave cycles invite.
Tall segmental block walls get woven geogrid layers every 2 vertical feet, reaching 4β8 feet back into compacted free-draining backfill β the mechanically stabilized earth (MSE) system behind the height capacity of Pavestone, Keystone, and Allan Block walls. Pressure-treated timber walls rely on deadman tie-backs at 6β8 ft spacing buried in the backfill, sized for combined earth pressure plus hydrostatic load when the dune sand saturates.
Engineered drainage is non-negotiable on a Long Beach wall: weep holes through the face every 4β6 feet, a chimney drain of #57 gravel wrapped in non-woven geotextile fabric tight behind the wall, and a perforated 4-inch PVC footing drain daylighted to grade or tied into an approved outlet. The system pulls water off the back face before hydrostatic pressure can build β precisely what keeps Long Beach walls standing through the seasonal heave and rainfall load that topples the un-drained ones.
Segmental concrete block and poured concrete take the lead for walls over 4 ft, surcharge-loaded sites, and any wall under City permit; pressure-treated timber covers short backyard walls with no driveway/pool/structural load; gabion baskets and rip-rap scrim bags fit the drainage-adjacent dune slopes where free drainage is required.
| Solution | Design Life | Drainage / Heave Resistance | Application |
|---|---|---|---|
| Segmental & Poured Concrete | 40–75+ Years | Very High (engineered MSE with geogrid) | Walls over 4 feet, driveway cuts, pool-deck retention, surcharge-loaded sites under the Long Beach Building Department permit requiring sealed engineering and maximum lifespan. |
| Natural Stone | 75+ Years (effectively permanent with drainage) | Very High | Premium curb-appeal walls and landscape-integrated retention across the Long Beach lakefront and Duneland Beach where appearance is a primary driver. |
| Gabion Baskets (PVC-coated wire) | 40–60 Years | Maximum (free-draining by design) | Slope and bank stabilization on drainage-adjacent lots, irregular slopes, and county drainage easement-edge work where free drainage is required. |
| Pressure-Treated Timber (CCA / ACQ) | 15–25 Years (Long Beach dune-sand wet–dry cycles) | Moderate (vulnerable to saturated dune-sand tie-back pull-out) | Short residential backyard grade walls under 4 ft with no surcharge, terraced gardens, and budget-friendly soil retention only. |
| Rip-Rap Scrim Bags (QUIKRETE FastSet) | 30+ Years | Maximum (free-draining hard armor) | Slope armor on drainage-adjacent terrain, irregular grades, and naturalized erosion control where a vertical wall isn't required. |
The Bottom Line: On Long Beach's frost-susceptible dune-bluff sites, segmental and poured concrete give the best long-term blend of height capacity and surcharge resistance; pressure-treated timber stays reserved for short walls with no surcharge; gabion and rip-rap scrim earn their keep along the drainage-adjacent slopes.

Retaining wall failure almost always tips its hand early: cap-block cracking, face-block displacement, clogged or missing weep holes, deadman tie-back pull-out, or settlement behind the wall. Spotting these clues in time is what keeps a minor Long Beach repair from snowballing into a full replacement.
The wall is carrying more earth and hydrostatic load than it can safely holdβ usually made worse by frost heave at the footing or clogged drainage behind the face.
Full-depth cap cracks usually signal frost heave shoving the wall outward, while displaced face blocks on segmental walls point to geogrid or backfill compaction that has let go.
Sinkholes and dips behind the wall mean dune-sand backfill is washing out through joints or weep holesβ a familiar sight after Long Beach rainfall events on walls where drainage was never engineered in.
Across Long Beach backyards and slope-stabilization sites, small retaining wall problems can deteriorate fast because frost heave, lake-effect rainfall hydrostatic pressure, and surcharge load from above gang up at once. The call that matters is whether shoring up the existing wall will do, or whether full replacement is the safer long-term play.
Repair is appropriate when damage is localized and the main wall alignment remains plumb and structurally sound.
Full replacement is the better option when failure is widespread or the wall has lost its capacity to resist earth pressure plus hydrostatic load.
Once the failure reaches the structural elements themselvesβ deadman tie-backs pulled out of saturated dune-sand backfill, geogrid layers torn or pulled out of the backfill envelope, a drainage system fully choked with sediment β the wall has typically burned through its design strength margin, and full replacement is usually the safer long-term decision.
Once a wall starts shedding the dune sand behind it, the next big rainfall event speeds the damage to nearby patios, driveways, pool decks, landscaping, and upland foundationsβ a pattern logged again and again across Long Beach after the the record 2019β2020 Lake Michigan high-water years and severe lakefront storm seasons.
Key Takeaway: Schedule an assessment when you see leaning, cap cracking, face-block displacement, voids, deadman pull-out, or weep-hole failure. A clear repair-vs-replacement recommendation prevents paying for short-term fixes that do not address the underlying drainage or surcharge problem.
After the site evaluation, we provide a written estimate based on the repair or replacement scope.
A Long Beach retaining wall project runs a clear sequence: site evaluation, geotech and surcharge assessment, the Long Beach Building Department permit coordination (and county drainage review where applicable), excavation and footing, drainage system installation, wall construction, geogrid or deadman reinforcement, backfill compaction, and final grading.
We measure wall length, proposed height, surcharge condition (driveway, pool, structure, sloped backfill), equipment access, and proximity to county drainage easements along Burns Waterway or Trail Creek.
We pin down the Long Beach Building Department permit requirements (walls >4 ft or surcharge-loaded), county drainage easement review, and sealed engineering scope, then assemble submittal packages to keep the schedule moving.
Crews dig to footing depth, set the perforated PVC footing drain in #57 gravel with geotextile, raise the wall face to design height, and lay in geogrid layers or deadman tie-backs as the specification calls for.
A retaining wall that holds in Long Beach takes more than the right material. Every phaseβ site evaluation, permit planning, rainy-season scheduling, footing depth, drainage system, wall construction, and backfill compaction β has to answer for frost heave, hydrostatic pressure, and surcharge load from above.
We size up wall length, proposed height, surcharge condition (driveway, pool, structure, or sloped backfill), existing wall condition on replacement projects, equipment access to the work area, and proximity to county drainage drainage easements on drainage-adjacent lots. We walk the slope, measure the grade change, confirm where equipment can stage, and verify whether the project boundary lands inside an easement or HOA design-review jurisdiction before quoting scope or cost.
We flag the applicable the Long Beach Building Department permit requirements (walls over 4 ft or any surcharge-loaded wall) and county drainage easement review from the wall location, project scope, and slope conditions, then prepare the documentation that keeps permits moving without schedule gaps. The wall system is engineered around site-specific data: material matched to wall height and surcharge load; footing depth set for lake-border dune sand subgrade; geogrid layer spacing or deadman tie-back placement calibrated to the expected earth and hydrostatic loads; the drainage system specification; and backfill compaction requirements.
Crews excavate to the design footing depth (typically 2β4 feet below grade for residential walls, deeper for surcharge-loaded walls per geotech), strip out any failed existing wall material, then lay the compacted gravel base or poured-concrete footing. The perforated 4-inch PVC footing drain goes in next, set in #57 gravel wrapped in non-woven geotextile fabric and daylighted to gradeβ the drainage backbone that shields the wall from Long Beach's lake-effect rainfall hydrostatic load.
The wall face is raised to design height β segmental block courses, poured concrete forms and rebar, timber tiers with deadman tie-backs, gabion baskets filled with stone, or dry-stacked natural stone, depending on the material. On tall walls, geogrid layers tie in every 2 vertical feet and run 4β8 feet back into the compacted free-draining backfill. Weep holes are cut through the face every 4β6 feet, the chimney drain of #57 gravel banks against the back face, and backfill goes down in 6β8 inch lifts with mechanical compaction. A poured concrete cap, segmental cap block, or fastened timber cap closes out the top. Final grading sheds surface water away from the wall and ties the new structure into the surrounding yard, driveway, or pool deck.
Key Takeaway: A Long Beach retaining wall built in proper sequenceβ site evaluation, permit coordination, footing depth, engineered drainage, wall construction with reinforcement, and compacted backfill β rides out the bluff's frost-heave and saturation cycles and lake-effect rainfall load far better than one thrown together without these conditions in mind.

A sound retaining wall keeps usable yard, holds slope and drainage damage off upland improvements, and reassures buyers during inspections in Long Beach's premium dune-bluff submarkets.
Long Beach rainfall events and frost heave chip away at usable yard space and creep toward nearby improvements. A retaining wall pins the slope and halts the ongoing loss before it reaches structures, driveways, or pool decks.
A failing retaining wall hands buyers a bargaining chip and raises a flag for homeowner insurance underwriters. A maintained wall with current permits clears away the uncertainty during due diligence.
Project records, material specs, the Long Beach Building Department permit documentation, and sealed engineering drawings put a paper trail behind the retaining wall's value for appraisers and insurers.
Residential property value in Long Beach turns on more than location. Slope stability, usable yard area, the condition of any retained-grade defense, and documented permitting all color how buyers, appraisers, lenders, and homeowner insurance underwriters size up a dune-bluff property.
Long Beach rainfall events and frost heave steadily eat usable yard space and creep up on nearby improvements. A properly engineered retaining wall stops the slope from retreating and guards the investment in structures, landscaping, driveways, and pool decks next to the grade change.
Buyers, inspectors, and Long Beach-area homeowner insurance underwriters look hard at wall lean, cap-block cracking, face-block displacement, voids behind the wall, and visible deterioration on a dune-bluff property. A stable, maintained retaining wall carrying current the Long Beach Building Department permits clears the uncertainty out of due diligence.
the county Assessor inspectors and lender appraisers confirm that significant site improvements are permitted and engineered. An unpermitted retaining wall over 4 ft tall, or a surcharge-loaded wall built without sealed engineering drawings, tends to surface during a refinance, a buyer's inspection contingency, or an the LaPorte County Assessor reappraisalβ and shrinks the value the wall adds to the documented improvement record. A wall built under a the Long Beach Building Department permit, with sealed engineering drawings on file, documents the improvement for the LaPorte County Assessor, lenders, title companies, and homeowner insurance underwriters.
Tackling slope failure early in Long Beach heads off the compounding reconstruction costs that trail a major rainfall event, especially once soil loss starts reaching driveways, foundations, pool decks, or other improvements near the wallβ a recurring pattern across dune-bluff backyards after the record 2019β2020 Lake Michigan high-water years and severe lakefront storm seasons.
Key Takeaway: A retaining wall protects property value by preserving yard, reducing slope and drainage risk, supporting insurer confidence, and documenting a significant engineered improvement to the property record.

This FAQ runs through retaining wall installation, repair, replacement, material selection, the Long Beach Building Department permit thresholds, county drainage easement coordination, drainage engineering for lake-border dune sand, and slope-stabilization options for Long Beach homes and businesses. It answers the questions we hear most from the Long Beach lakefront, Duneland Beach, and the dune-bluff neighborhoods across LaPorte County.
Watch for the wall leaning or bowing outward, full-depth cap-block cracking from frost heave, face-block displacement on segmental walls, visible voids or settlement behind the wall, blown-out weep holes, deadman tie-back pull-out, and erosion gullies opening alongside the wall in heavy rain.
Each of these usually means the wall is no longer holding soil and hydrostatic load the way it should. On the Long Beach bluffs, lake-border dune sand subgrade paired with intense lake-effect rainfall can turn hairline cracks or a single clogged drain into major failure inside one or two wet seasons.
An early inspection tells you whether the wall can be repaired or whether full replacement is the safer long-term solution.
Replacement is usually the better option when the wall is leaning more than 1 inch per foot of height, showing widespread cap cracking, face-block displacement, deadman or geogrid pull-out, or major void formation behind the structure.
If repeated repairs are becoming expensive after every wet season, or repair costs approach 50% of replacement cost, full replacement is often the smarter investment.
A new retaining wall also improves long-term slope stability, restores engineered drainage, and reduces future repair risk.
Poured and segmental concrete (40β75+ year design life) and natural stone (effectively permanent when properly drained) deliver the longest service for Long Beach retaining walls, where lake-border dune sand frost-heave cycles and intense rainfall quickly fatigue lower-tier materials.
Gabion baskets (40β60 years) suit slope and bank stabilization where free drainage is a feature; pressure-treated timber (15β25 years in Long Beach dune-sand freezeβthaw cycles) remains the most economical choice for short residential backyard walls under 4 feet with no surcharge.
The best material depends on wall height, surcharge load, drainage requirements, and expected service life β not just initial cost.
Design life depends on material and drainage. On LaPorte County properties, poured and segmental concrete walls typically deliver 40β75+ years of service; natural stone is effectively permanent with proper drainage.
Gabion baskets reach 40β60 years; composite block systems 40β50 years; galvanized metal 30β50 years; pressure-treated CCA timber lasts 15β25 years in Long Beach's freezeβthaw and saturation cycles.
Service life on LaPorte County properties depends on correct footing depth (typically 2β4 feet below grade for residential walls, deeper for surcharge), drainage system (weep holes every 4β6 ft, chimney drain, PVC footing drain), geogrid layer spacing on MSE walls, and proper backfill compaction.
Long Beach retaining wall construction follows a four-phase process. Phase 1 - site evaluation: walk the property, measure wall length and proposed height, identify the surcharge load, confirm equipment access, and identify whether the project falls within an county drainage drainage easement.
Phase 2 - design and permitting: select material for wall height and surcharge, calibrate footing depth for lake-border dune sand, size geogrid or deadman reinforcement, specify the drainage system, and prepare the Long Beach Building Department permit and sealed engineering documentation where required.
Phase 3 - construction: excavate to footing depth, install drainage system (perforated PVC footing drain in #57 gravel with geotextile), build the wall face to design height with geogrid layers or deadman tie-backs as specified.
Phase 4 - backfill, compact and finish: place free-draining backfill in 6β8 inch lifts with mechanical compaction, install chimney drain and weep holes, pour or fasten the cap, then final grade to direct surface water away from the wall.
Most residential Long Beach retaining wall projects take 1–4 weeks from mobilization to final grade. Small backyard timber walls wrap in 3–5 working days, standard segmental-block walls with drainage typically run 1–2 weeks, and larger poured-concrete or MSE walls under permit can extend to 3–6+ weeks.
Long Beach's rainy season (spring snowmelt and AprilβJune rains) can delay excavation and backfill compaction β saturated lake-border dune sand subgrade cannot be properly compacted and must dry out. Permit lead time (the Long Beach Building Department review, county drainage coordination where applicable, sealed engineering) adds 4–10 weeks before active construction starts.
Total timeline from contract signing to completed wall is typically 5–14 weeks for a residential Long Beach project, including permitting and construction.
Long Beach's lake-border dune sand subgrade — wind-deposited dune sand and lacustrine silt over a seasonally high water table — teams up with about 38 inches of precipitation annually to produce frost-heave cycles, hydrostatic pressure, and saturated bearing failure against any wall built without engineered drainage.
To counter that, footings usually reach 2–4 feet below grade for residential walls (deeper for surcharge), and drainage systems combine weep holes every 4–6 ft, a chimney drain of #57 gravel wrapped in non-woven geotextile, and a perforated 4-inch PVC footing drain daylighted to grade.
Access hurdles on Long Beach lots include narrow gates or fenced backyards that cap excavator size, overhead utility lines, mature oak and pecan root systems common on the Long Beach lakefront, and the need to stay clear of the county drainage easement footprint on drainage-adjacent lots.
In the Long Beach Building Department, any retaining wall over 4 feet tall measured from the bottom of the footing needs a building permit through the Long Beach Building Department, and walls carrying a surcharge β driveway, pool, structure, or sloped backfill β typically need sealed engineering drawings no matter the height.
Walls inside an county drainage drainage easement on Burns Waterway, Trail Creek, or the Grand Calumet River trigger county drainage review and may be off-limits entirely within the easement footprint. HOA design review applies on the Long Beach lakefront and in Duneland Beach. Permit needs come down to exact location, wall height, and surcharge load. Reviewing early heads off redesign, schedule slip, and stop-work orders during construction.
Yes. A properly engineered retaining wall pins the slope, intercepts hydrostatic pressure behind it with weep holes and a chimney drain, and routes surface water away through final grading and a perforated PVC footing drain.
On drainage-adjacent lots, gabion baskets and rip-rap scrim-bag systems can hold a slope where a vertical wall isn't required or allowed inside the county drainage easement. A retaining wall won't stop flooding during a major rainfall event like the record 2019β2020 Lake Michigan high-water years and severe lakefront storm seasons β but it sharply cuts ongoing soil loss, slope creep, and upland damage.
For the strongest protection, retaining walls are often paired with regrading, French drains, and downspout extensions that keep surface water from reaching the wall in the first place.
A retaining wall is built to hold back soil on slopes β backyard grade changes, driveway cuts, pool-deck retention, terraced gardens, and slope and bank stabilization β where soil pressure and hydrostatic load are the primary design drivers, with no open-water wave component.
A bulkhead is a shoreline retaining wall built mainly to resist soil pressure and modest wave or wake action where land meets the water β see our bulkhead construction services for sheltered freshwater waterfront sites and low-energy inlets. A seawall is engineered for large local ship channels and major bay or lake systems where hydrodynamic load and storm surge dominate.
Using the correct structure matters β a retaining wall built without drainage will fail under a wet season, and a seawall is overbuilt and over-permitted for an inland slope.
To prepare a written Long Beach retaining wall estimate, we typically need: property address or GPS coordinates, approximate wall length in linear feet, proposed wall height, photos of the area where the wall will go, and the surcharge condition behind the wall (open yard, sloped backfill, driveway, pool, or structure).
Recent rainfall or slope-failure history at the site is helpful, plus photos showing wall lean, cap cracking, face-block displacement, void formation behind the wall, or weep-hole failure for replacement projects. HOA constraints (if applicable), county drainage easement proximity, and access notes — fenced backyard, tree roots, overhead utilities, adjacent structures — affect mobilization cost.
With this information, we can usually return a written line-item estimate within 3–5 business days, plus an in-person site evaluation if needed.
Long Beach retaining wall pricing starts at $15/SF for pressure-treated timber (residential under 4 feet, no surcharge), $20/SF for gabion baskets, $25/SF for segmental or poured concrete, $25/SF for natural stone, and $30/SF for brick. Retaining wall repair starts at $25/SF. Final pricing depends on wall height, drainage system, geogrid or deadman reinforcement, surcharge load, footing depth in lake-border dune sand, and site access.
