NAACC Assessment Protocol

Trained Lead Observers certified to assess crossings use a uniform protocol throughout the thirteen states region.

This protocol includes observations of the crossing (for example road type, flow condition, crossing alignment) and of the structure itself (for example material, shape, dimensions).

The Stream Crossing Survey Data Form Instruction Guide explains this survey protocol using paper field data forms, and this guide describes how to enter the data offine on an electronic device.
