Storm Water Design Criteria Manual —April 2019 . Storm Water Design Criteria Manual Regulations and Criteria Manuals. Although review activities are primarily the responsibility of the Planning and Development Review department, the Watershed Protection Department assists with some stormwater and environmental reviews. Find links to criteria manuals on this page. This combined staff is responsible for reviewing and approving Introduction 3.6.1 The Small Watershed Hydrograph Method is a method for developing a curvilinear design hydrograph for small to moderate size drainage areas (less than 640 acres) which peaks at a designated flow rate and contains a runoff volume consistent with the design rainfall. Applications 3.6.2 evaluating current TxDOT design methodology, and reviewing literature and research data to produce useful design aids. A user-friendly PC-based computer program was developed for distribution to each district by TxDOT that should accompany this report and the TxDOT Storm water Guidelines for Construction Activities. The benefits of the computer Section 1: Introduction Purpose of A Pump Station A pump station mechanically lifts storm water runoff from a gravity fed collection cistern to a discharge place or outfall. In general, gravity outfalls are the primary and preferred means of releasing flow from storm drain systems.
