The correct answer emphasizes the importance of adhering to what is indicated on the permit when determining trench bottom depths. Permits are issued by local building authorities and are based on site-specific conditions, intended uses, and relevant regulations. They ensure that the work aligns with safety standards, zoning laws, and other legal requirements unique to the location of the construction project.

While the other criteria can influence trench depth in certain circumstances, they do not carry the same weight as the requirements specified in the permit. Site conditions, while necessary to consider, might vary significantly from one location to another. Standard building codes provide general guidelines but may not account for unique site or permit-specific requirements. Similarly, installation instructions from the manufacturer, while essential for certain products, may not address all the regulatory concerns tied to trench depth. Therefore, the permit remains the definitive guide for compliance in trench depth determination, ensuring safety and legal adherence on the project site.
