This section of the describes the conditions under which state, federal and local financing of drainage construction costs are to be shared. In general TxDOT’s responsibility includes:

Although TxDOT can adjust a facility to accommodate public improvement works that directly benefit the operation of the highway, it is not required to make changes to highway facilities just to accommodate development in the drainage area.

Parties wishing to discharge drainage onto or across the state highway right of way, where there is no existing drainage system, must obtain approval from TxDOT and provide design, construction, and maintenance costs. Local governments wanting to connect to a TxDOT drainage system must first have approval from TxDOT, and then must bear the cost of collecting and carrying its water to the TxDOT system as well as contribute a share of the TxDOT system costs.
