What requirement must be met for a lot to be excavated in this scenario?

In the context of excavation, having a uniform cut depth is crucial for several reasons. A uniform cut depth ensures that the excavation is consistent throughout the area, which helps to maintain the structural integrity of the site. It is vital for proper drainage and prevents issues such as settling or shifting of the ground after the excavation is completed. Additionally, a consistent cut aids in achieving the designed elevations and contours of the site, making it easier to implement subsequent construction activities.

While factors such as the terrain being flat, access for large machinery, and weather conditions are important considerations in an excavation project, they do not directly address the fundamental requirement of maintaining the correct and uniform cut depth for effective and safe excavation practices.
