Chapter 3: Hydraulic Practices and Governing LawAnchor: #i1006593
Section 1: Overview
This chapter briefly describes the laws and related policies that affect hydraulic design for TxDOT projects. Federal and state regulations and rules have the force of law, and compliance is not at the discretion of TxDOT.
Federal Highway Administration (FHWA) sets forth policy and guidance in the Federal Aid Policy Guide (FAPG). The primary policy for drainage is 23 Code of Federal Regulations (CFR) 650, which is described later in this chapter.
