Drainage Report. 1. DRAINAGE ELEMENTS The Engineer shall perform field work and analysis necessary to design the drainage elements for designated locations and sections of roadways. The Engineer shall:
Drainage Report. The scope for work for this Drainage Mitigation Study is to support additional roadway development. • Drainage Mitigation Study The purpose of this task is to prepare a Drainage Mitigation Study to determine the 100-year storm impacts resulting from construction of the project and to develop and analyze alternatives to mitigate these impacts. The following tasks describe the work to be performed: Prepare 100-year storm drainage area maps for existing and proposed conditions, which include the typical Fort Bend County roadway improvements within the project limits and the proposed right of way (ROW). Compute existing and proposed peak flows based on the Fort Bend County methodology within the existing and proposed ROW. Compute required 100-year storage volumes within the ROW to determine mitigation requirements for the proposed condition. Prepare existing and proposed hydrographs at each outfall location to develop mitigation alternatives to implement the required 100-year mitigation. Prepare a Drainage Mitigation Preliminary Engineering Report to summarize and document the findings of this study. The report will include the following items at a minimum: Provide electronic draft copies of the report for PMT review and upon approval.
Drainage Report. 1. The Engineer shall prepare a single comprehensive drainage study and report of the project area. The report shall be divided into two (2) phases: The first phase shall include the following items:
Drainage Report. A drainage report is required if the Grade Separation Project necessitates changes in existing drainage patterns or increases in drainage flow on Railroad right-of-way. See Section 4.5.2 and 4.5.3 for hydraulic criteria to be used.
Drainage Report. 4 Developer shall prepare a preliminary Drainage Report(s) for the Project drainage system(s) in 5 accordance with Chapter 4 of the ADOT Highway Drainage Design Manual, Hydraulics and 6 shall include all calculations and analysis in the report as required by the Contract Documents.
Drainage Report. 1. The Engineer shall prepare a single comprehensive drainage study and report of the project area. The report shall be divided into two phases: The first phase will include the following items: WAs Used DocuSign Envelope ID: 56C9F445-711D-4155-8CAC-4A873A2298E4 Collect as-built drawings and complete field investigations Obtain existing HEC-2 or HEC-RAS models from applicable drainage authorities to the extent possible, for use in analysis and determination of the existing 2, 5, 10, 25, 50, 100 and 500 year, water surface elevations at bayous, creeks, and ditch crossings along the project. This data will be utilized in the development of design roadway profiles. Profile of natural ground along each proposed grade line of the roadway. Profile of tentative proposed grade line of the roadway. Profile of existing roadway. Identify the existing drainage outfalls. Identify the names of existing creeks, bayous, ditches and reservoirs within the project limits.
Drainage Report. The ENGINEER shall prepare a Drainage Report for the well site and submit to the CITY’s Engineering Department.
Drainage Report. A Drainage Report will be completed for this project in accordance with City of Tempe standards, based on our preliminary engineering design. The results of this report will be incorporated in the final grading and drainage design. Storm water facilities and storm drain systems will be sized to collect, convey, and retain storm water generated onsite. Offsite or regional drainage issues are not anticipated for this project.

This data will be utilized in the development of design roadway profiles. Profile of natural ground along each proposed grade line of the roadway. Profile of tentative proposed grade line of the roadway. Profile of existing roadway. Identify the existing drainage outfalls. Identify the names of existing creeks, bayous and ditches within the project limits.
Drainage Report a. The report must document and justify all data, boundary conditions, assumptions, methodologies, and results. The text, tables, exhibits, and appendices must document clearly and concisely the work performed and results found. The report must provide recommendations for critical review by the State. Such recommendations may include corrective actions by the State, corrective actions by others, or need for further detailed analysis such as an unsteady model analysis or the development of mitigation measures. The Engineer shall save text, tables, exhibits, appendices (including computer models) on a compact disc and included the disc with DocuSign Envelope ID: 82ABE615-A8AB-4523-B50C-6FA5DBECD719 each report. The report must be signed and sealed by a professional engineer. FUNCTION CODE 160 (162) - ROADWAY DESIGN SIGNING, PAVEMENT MARKINGS AND SIGNALIZATION (PERMANENT)
