Charleston's Drainage Problem Is Unique — and Getting Worse
Charleston is one of the most flood-prone cities in the United States. Between sea level rise, tidal flooding, aging stormwater infrastructure, and explosive residential development, water management has become one of the most urgent home maintenance challenges in the area. Even properties miles from the coast deal with chronic yard flooding, standing water, and foundation moisture after heavy rain.
The culprit is usually a combination of factors — flat terrain with poor natural drainage, clay-heavy soil that resists percolation, and neighborhoods where grading was done at a subdivision level without accounting for individual lots. The result is water that has nowhere to go except against your foundation, into your crawl space, or across your lawn for days at a time.
