What size LDA is required to comply with stormwater management regulations in Critical Protection Buffer Areas (CPBA)?

In Critical Protection Buffer Areas (CPBA), the requirement for a Land Disturbance Activity (LDA) to comply with stormwater management regulations is set at 1 acre or more. This threshold is established to ensure that any significant land disturbance, which could lead to increased stormwater runoff and potential negative impacts on water quality and habitat, is appropriately managed and mitigated.

The rationale behind this requirement is that disturbances of this size are likely to have a considerable effect on the surrounding environment. By regulating land disturbances that meet or exceed this size, the regulatory framework seeks to minimize the potential for pollutants to enter water bodies and to maintain the ecological integrity of these sensitive areas. Therefore, any land disturbance activity of 1 acre or more must adhere to specific management practices to control stormwater runoff, protect water quality, and preserve the natural environment within these critical areas.
