Guidelines and criteria for drainage related to land development

The following documents contain the guidelines, procedures, and criteria for stormwater outfalls or modifications to the TxDOT Houston District drainage infrastructure. The documents were prepared to assist land development and site engineers with a general methodology for the hydrologic and hydraulic analysis required within the Houston District. The documents were prepared for typical permit projects and are not comprehensive to be applicable to all sites. If further clarification is required, please contact the Houston District Hydraulic group. Houston District Hydraulics can be contacted by emailing HOU_HYD_Permits@txdot.gov.
