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.

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.

Frequently Asked Questions

What stormwater regulations apply to properties in Charleston, SC? expand_more
Charleston properties fall under the City of Charleston Stormwater Design Standards and the Charleston County stormwater program. Both operate under SCDHEC NPDES MS4 permits that require property owners to maintain stormwater BMPs in working condition. Properties with retention ponds, detention basins, bioretention areas, and other engineered systems must be inspected and maintained annually. The City has been tightening enforcement as development pressures and tidal flooding events increase.
How does tidal flooding affect stormwater systems in Charleston? expand_more
Charleston's historic peninsula and low-lying neighborhoods experience some of the most frequent tidal flooding on the East Coast. King tides and storm surge push saltwater into stormwater outfalls, back up drainage systems, and accelerate erosion around pond banks and outlet structures. Stormwater BMPs in tidal zones require more frequent maintenance. Sediment accumulates faster, metal structures corrode, and vegetation management becomes more complex. AUE Land designs maintenance programs that account for Charleston's unique tidal challenges.
Who provides stormwater BMP inspections in Charleston? expand_more
AUE Land provides stormwater BMP inspections, maintenance, and compliance services throughout Charleston and the surrounding Lowcountry. We inspect retention ponds, detention basins, bioretention cells, underground systems, and outlet structures. We provide the documentation required by the City of Charleston and Charleston County, and we perform the physical repairs when deficiencies are found.
How much does stormwater maintenance cost in Charleston? expand_more
Costs vary based on the type, size, number, and condition of your stormwater systems. Charleston properties with tidal exposure or deferred maintenance typically require more upfront work. AUE Land offers site assessments. We walk your property, evaluate every BMP, and deliver a detailed proposal. Annual maintenance agreements are available for ongoing compliance support.
Can AUE Land handle stormwater work in Charleston's historic district? expand_more
Yes. We understand that work in Charleston's historic peninsula requires sensitivity to access constraints, preservation requirements, and tight site conditions. We use appropriately sized equipment, coordinate with property managers on scheduling, and ensure that stormwater repairs don't disturb adjacent historic features. We have experience working in constrained urban environments where full-size equipment can't access the site.
