Floodplain Drainage Design Consultation
Budget: $250 – $750 USD
I own a parcel that sits squarely on a flood plain. A basic ditch exists, yet even moderate storms leave parts of the land underwater. My primary goal is to reduce flood risk while still keeping the area functional for future landscaping or light agricultural use.
Here’s what I need from you:
• Assess the current conditions – topography, soil, and the limited drainage already in place (survey files, drone imagery, or a brief site visit can be provided).
• Recommend practical drainage system improvements that comply with local codes and can be phased in if necessary.
• Propose water-retention structures such as detention basins, swales, or rain gardens that slow runoff without sacrificing too much surface area.
• Outline soil and land-grading techniques that naturally direct water to the new infrastructure.
Deliverables (medium-detail scope):
1. A concise engineering report (PDF) explaining findings, design assumptions, and hydraulic calculations.
2. A scaled site layout drawing in CAD/GIS showing proposed drains, retention areas, discharge points, and tie-ins to existing features.
3. A preliminary bill of quantities with order-of-magnitude cost estimates and an implementation timeline.
4. Maintenance guidelines so the solution remains effective over time.
If you’ve used tools like HEC-RAS, Civil 3D, or SWMM on previous flood-plain or stormwater projects, highlight that experience and share relevant examples. Target delivery is within two weeks after you have all site data, but let me know if you need more time. I look forward to your expert guidance in turning this flood-prone land into a safer, better-drained property.
