What type of seeding should be applied immediately to areas that are at rough grade for 14 days or more?

When an area is at rough grade for 14 days or more, applying temporary seeding is essential for several reasons. Temporary seeding is typically used to quickly stabilize the soil, preventing erosion and sediment loss, especially in conditions where the ground is exposed and susceptible to rainfall and wind erosion.

This type of seeding involves the use of quick-growing grasses or cover crops that help establish a vegetative cover rapidly. The goal is to provide immediate protection to the soil while awaiting the final landscaping or permanent vegetation installation. Temporary seeding serves as a short-term solution that enhances soil stability, reduces runoff, and minimizes the transport of sediment into surrounding waterways.

Other options, such as permanent seeding, would not be suitable because they involve longer-growing species that require more time to establish and would not provide the immediate erosion control needed for areas at rough grade. Delayed and seasonal options similarly do not address the urgent need for stabilization during the critical period when the soil is exposed.

Therefore, temporary seeding is the appropriate method to implement under such conditions to protect the site effectively from erosion.
