Inverse Condemnation: Suing Alabama Municipalities for Stormwater Runoff and Flooding Damage

Understanding Inverse Condemnation in Alabama

When the government wants your land, they use eminent domain to buy it. But what happens when the government damages your property without ever officially taking it? This is called inverse condemnation. In Alabama, one of the most common reasons for inverse condemnation is stormwater runoff. If a local municipality, such as the City of Mobile Public Works Department, Mobile or the City of Montgomery Engineering Department, Montgomery, approves a new upstream development or improperly designs a drainage culvert, the resulting floodwaters can destroy your home or business. If you are facing severe water damage caused by public infrastructure, you must hire a local real estate litigation attorney from our US Lawyers Catalog to hold the government accountable.

Proving the City 'Took' the Property via Water Damage

To win an inverse condemnation lawsuit, you must prove that the government's actions effectively took your property by destroying its value or your ability to use it. Under Ala. Const. Art. XII, § 235, municipalities must provide just compensation for property taken, injured, or destroyed by the construction of public improvements. Occasional puddles in your yard are not enough. As established in cases like McClendon v. City of Boaz, 395 So. 2d 21 (AL Supreme Court 1981), the flooding must be a recurring, permanent, or severe physical invasion directly caused by the city's drainage system or roadwork.

The Strict Two-Year Notice of Claim Requirement

Suing a city in Alabama requires navigating strict procedural traps. Under Ala. Code § 11-47-23, while general tort claims against a city carry a six-month deadline, inverse condemnation claims are subject to a two-year presentation requirement. As confirmed in McClendon v. City of Boaz, 395 So. 2d 21 (AL Supreme Court 1981), a taking claim under Ala. Const. Art. XII, § 235 must be presented to the municipal clerk within two years from its accrual. This notice of claim must be submitted in writing to the municipal clerk detailing the property damage and the amount of compensation sought. If you miss this two-year window, your inverse condemnation claim will be barred, regardless of how much damage the flood caused.

Hiring Hydrologists as Expert Witnesses

Proving that the city is at fault requires more than just photographs of a flooded basement. Cities will typically blame the flooding on heavy rainfall or acts of nature. To defeat this defense in courts like the Mobile County Circuit Court, Mobile or the Shelby County Circuit Court, Columbiana, your attorney will hire a hydrologist or civil engineer. These expert witnesses will study the topography, calculate water flow rates, and prove scientifically that the city's specific pipe design or approved upstream concrete poured water directly onto your land.

Calculating Damages: Diminished Property Value vs. Remediation Costs

If your inverse condemnation claim is successful, the court must determine how much the city owes you. Damages are generally calculated in two ways: diminished property value or remediation costs. If the flooding is permanent and cannot be fixed, the city must pay you the difference between your property's value before the public project and its value after the flooding began. Alternatively, if building a new retaining wall and drainage system can save the property, the city may be ordered to pay the cost of those repairs.
