How can changes in site conditions lead to non-compliance?

Changes in site conditions can significantly impact compliance with stormwater management and erosion control regulations. When site conditions change—such as alterations in topography, soil type, or land use—there is often a need for adjustments in the original design of stormwater management systems. This could involve the redesign of detention basins, adjustments to outfall locations, or even entirely new approaches to handling runoff.

If these changes are not addressed through redesigns or updates to the stormwater management plan, the original strategies may become ineffective, leading to potential violations of regulations. Non-compliance could arise if the management practices fail to adequately mitigate the impacts of stormwater runoff, resulting in increased erosion, sedimentation, or water quality issues, thus not meeting local, state, or federal standards. Compliance relies heavily on maintaining effective and functional systems that are responsive to current site conditions.
