Navigable Area Surveys are basic hydrographic surveys with restricted area coverage. The coverage is reduced by omitting require­ments for: 1. Development of the 0‑foot depth curve and foul, nearshore areas not considered navigable; 2. Complete field edit of the survey area. Naviga­ble Area Surveys may also be restricted to the main navigable channel or corridor.
