 Overview:
(Revised 4/23/2009)
In an effort to improve safety and protect the public’s investment in its infrastructure, the Federal Highway Administration (FHWA) enacted changes in the National Bridge Inspection Standards (NBIS - CFR 650) with regards to bridge scour. A Plan of Action (POA) is required to be prepared for all bridges determined to be scour critical (NBI item 113 scour code 1, 2 or 3). More recently, FHWA directed that bridges classified as having an unknown foundation (NBI item 113 scour code U) are to be treated as scour critical and require a POA.
Letters from the Department to affected local agencies have been transmitted providing guidance to develop the POAs. The letters provide deadlines for compliance and the lists of scour critical bridges and bridges with unknown foundations that must have POAs developed. The POAs must be developed to ensure that local agencies remain eligible for all federal Title 23 funds.
Completed plans must be submitted to your Caltrans District Local Assistance Engineer (DLAE) to demonstrate compliance with federal law.
