What is the least depth at the southernmost part of Pier 11?

The least depth at the southernmost part of Pier 11 is correctly identified as 31.4 feet. This specific measurement is significant for various reasons, particularly for maritime operations. Knowledge of water depths is critical for ensuring that vessels can safely navigate and dock without running aground.

In this instance, a depth of 31.4 feet indicates that the area has been designed or maintained to accommodate larger vessels, which require more clearance than smaller boats. Such measurements are vital infrastructure components because they guide decisions related to shipping, maritime safety, and environmental considerations.

Factors that could influence the recorded depths include seasonal changes in water levels, sedimentation, and dredging activities aimed at maintaining or increasing navigability. Therefore, the chosen answer reflects an understanding of maritime operational standards and aids in logistics planning and scheduling at Pier 11.
