Stormwater Management & Erosion Control in Charleston, SC
BMP inspections, erosion control, drainage repair, and stormwater compliance for Charleston properties, from the peninsula to West Ashley, James Island, and Johns Island.
Charleston floods more than almost any city in the Southeast, and your stormwater systems are the first line of defense.
The City of Charleston and Charleston County both operate under SCDHEC NPDES MS4 permits that require property owners to maintain stormwater BMPs in working condition. Between tidal flooding, intense summer storms, and hurricane season, Charleston's stormwater infrastructure takes a beating that most inland cities never experience.
If you own or manage a property in Charleston with a stormwater pond, detention basin, bioretention area, or any engineered drainage system, you are responsible for:
- Annual inspections of all stormwater control measures
- Routine maintenance including sediment removal, vegetation management, and structural repairs
- Compliance documentation that proves your systems are functioning as designed
- Timely repairs when inspections reveal deficiencies
Charleston's rapid growth, particularly in West Ashley, James Island, Johns Island, and the Cainhoy peninsula has added thousands of new stormwater BMPs over the past decade. Many early-phase developments from the 2010s building boom are now hitting the point where deferred maintenance becomes visible: eroding pond banks, clogged outfalls, and failing outlet structures.
AUE Land serves Charleston from our Bluffton headquarters, less than two hours south on US-17. We understand Lowcountry soil conditions, tidal dynamics, and SCDHEC requirements because we work in this environment every day.
What we do for Charleston properties.
Stormwater BMP Inspection & Maintenance
Annual inspections, sediment removal, outlet structure repair, vegetation management, and compliance documentation for retention ponds, detention basins, bioretention systems, and underground facilities throughout Charleston.
Erosion Control & Shoreline Stabilization
Pond bank restoration, slope repair, bioengineered stabilization, riprap installation, and native plantings. Charleston's tidal influence and saturated soils create persistent erosion challenges that require engineered solutions, not just patching.
Grading & Drainage Correction
Swale reshaping, ditch maintenance, site regrading, and drainage redirection. Charleston's flat terrain and high water table mean that even small grading errors create standing water. We restore proper positive drainage across your site.
Storm Drainage Infrastructure
Catch basin repair, storm pipe replacement, outfall clearing, and hydro-vac cleaning. When tidal backflow deposits sediment in your underground systems or outfalls collapse from corrosion, we repair and replace the infrastructure.
Emergency Repair
Post-storm washout repair, slope failure response, outfall collapse stabilization, and emergency grading. Charleston's hurricane and tropical storm exposure means damage can happen fast. We mobilize quickly from our Bluffton base.
Properties we serve in the Charleston area.
HOAs & Planned Communities
From Daniel Island and Park West to West Ashley and Johns Island, Charleston's residential communities rely on hundreds of stormwater ponds and BMPs. We keep these systems compliant so boards avoid fines and residents avoid flooding.
Commercial Properties
Retail centers along the King Street corridor, Savannah Highway commercial strip, and Mount Pleasant Town Centre all operate stormwater systems that require annual maintenance. We handle the inspections, documentation, and physical repairs that keep commercial properties in compliance.
Developers
Charleston's booming construction market, particularly in West Ashley, James Island, Johns Island, and Cainhoy requires stormwater management plans approved by the City or County. We perform BMP installation, grading, and erosion control that developers need to meet permit conditions.
Municipal & Institutional
Municipal facilities, schools, hospitals, and public infrastructure throughout Charleston County require stormwater compliance. We work with public entities on inspection programs, maintenance contracts, and capital improvement projects.
Historic Property Managers
Charleston's historic properties face unique drainage challenges: aging infrastructure, constrained sites, and preservation requirements. We provide stormwater solutions that respect the character of these properties while meeting modern regulatory standards.
Lowcountry stormwater requires Lowcountry experience.
Charleston's stormwater challenges aren't the same as Raleigh's or Atlanta's. Tidal influence, high water tables, sandy soils, salt exposure, and hurricane-force storms create conditions that generic stormwater contractors aren't equipped to handle. A detention basin in Charleston behaves differently than one in Charlotte because the groundwater is three feet below the surface instead of thirty.
AUE Land works in Lowcountry conditions every day. We know which soils erode first, which outlet structures fail from tidal corrosion, and what the City's inspectors prioritize. When your property needs attention, we bring the equipment and the expertise, not a subcontractor from out of state.
