If an area is not at final grade and will remain dormant for more than 14 days, when must temporary stabilization be applied?

Temporary stabilization must be applied within 7 days if an area is not at final grade and will remain dormant for more than 14 days. This requirement is in place to minimize soil erosion and sediment runoff during construction activities. When a site is disturbed and not active, leaving it exposed can lead to increased erosion, especially during rainfall events. The application of temporary stabilization measures, such as seeding or mulching, helps to protect the soil and reduce the risk of sediment loss into stormwater systems. This timeframe is crucial for site management practices in order to comply with stormwater regulations and protect water quality.

Choosing a timeframe longer than 7 days, like 14 days, does not adequately address the immediate risks associated with disturbed soils. The 7-day requirement is a proactive measure to ensure that sites are managed effectively and sustainably until they are either further developed or brought to final grading.
