Storm Drains Sample Clauses

Storm Drains. The Engineer shall provide the following services: 1. Design and analyze storm drains using software as approved by the State. 2. Size inlets, laterals, trunk line and outfall. Develop designs that minimize the interference with the passage of traffic or incur damage to the highway and local property in accordance with the State’s Hydraulic Design Manual, District criteria and any specific guidance provided by the State. Storm drain design software shall be selected as directed by the Work Authorization. 3. Determine hydraulic grade line starting at the outfall channel for each storm drain design. Use the design water surface elevation of the outfall as the starting basis (tailwater) for the design of the proposed storm sewer system.

Storm Drains. If applicable to the development, Developer shall construct a storm drainage system in accordance with the Development Plan and Town shall accept the same within the proposed right-of-way lines for ownership and maintenance.

Storm Drains. The Engineer shall provide the following services: 1. Design and analyze storm drains using software as approved by the Owner. 2. Size inlets, laterals, trunk line and outfall. Develop designs that minimize the interference with the passage of traffic or incur damage to the highway and local property in accordance with local drainage ordinances, the TxDOT Hydraulic Design Manual, and any specific guidance provided by the Owner. Storm drain design software shall be selected as directed by the task order. 3. Determine hydraulic grade line starting at the outfall channel for each storm drain design. Use the design water surface elevation of the outfall as the starting basis (tailwater) for the design of the proposed storm sewer system. 4. Calculate manhole head-losses. Compute manhole head losses as per FHWA’s HEC-22. 5. Limit discharge into existing storm drains and existing outfalls to the capacity of the existing system, which will be determined by the Engineer. Evaluate alternate flow routes or detention, if necessary, to relieve system overload. Determine the amount of the total detention storage to control storm drain runoff for the design frequency based on hydrograph routing for the full range of frequencies (50%, 20% 10%, 4%, 2%, 1%, and 0.2% AEP), as well as a rough estimate of the available on-site volume. When oversized storm drains are used for detention, the Engineer shall evaluate the hydraulic grade-line throughout the whole system, within project limits, for the design frequency or frequencies. The Engineer shall coordinate with the Owner any proposed changes to the detention systems. 6. Identify areas requiring trench protection, excavation, shoring, and de-watering.
