Hydraulic Stormwater Drainage Study
Budget: $30 – $250 USD
I need a focused hydraulic analysis that will lead to a practical stormwater drainage system design for a new BF civil project I am undertaking. The scope centers on evaluating runoff, sizing conveyance elements, and recommending layouts that keep the site free from surface flooding under local design-storm criteria.
I will provide you with the site plan, topographic data, and rainfall-intensity curves; you translate that information into a clear set of design calculations and drawings. Typical tools such as EPA-SWMM, HEC-RAS, or Civil 3D’s stormwater modules are acceptable—feel free to suggest your preferred workflow as long as the end results remain fully traceable.
Key deliverables:
• Hydrologic and hydraulic computations (electronic spreadsheets and native model files).
• Annotated drainage layout showing inlets, pipes, channels, and outfall locations, ready for inclusion in construction documents (PDF + CAD).
• Brief technical memo summarizing methods, assumptions, and compliance with local regulations.
I’ll review the draft submittal, provide any comments, and expect a finalized package that can be stamped by my engineer of record. If you have recent experience with storm events, detention sizing, or green-infrastructure allowances, please mention it when you respond.
