Pond and Small Dam Design
Engineering for farm ponds, recreational ponds, small dams and spillways, including state dam safety permits.
What the work involves
Pond design covers site suitability, soils for water retention, embankment design, principal and emergency spillways, and outlet pipes. Larger embankments may be regulated dams under state dam safety programs, requiring an engineer's design and periodic inspections. The USDA NRCS publishes widely used pond design guidance (Agriculture Handbook 590).
Local conditions we plan for
- New Madrid Seismic Zone in the southeast (Bootheel)
- Karst and sinkholes in the Ozarks
- Missouri and Mississippi River flooding
- Expansive clay soils
Building code: No statewide IBC/IRC; codes adopted by local jurisdictions (ICC adoption chart, April 2026).
When you need it
- Building a farm or recreational pond
- Embankment height or storage may be state-regulated
- Existing pond leaks or spillway erodes
- Dam safety agency orders inspection or repair
Frequently asked questions
How much does pond and Small Dam Design cost?
Across the US, pond and Small Dam Design usually costs $2,000 to $30,000. Estimate. Small unregulated ponds are at the low end; state-regulated dams cost far more.
How long does pond and Small Dam Design take?
Plan on 3 to 12 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Do I need a licensed PE for pond and Small Dam Design?
In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.
How do I verify an engineer's license in Missouri?
Engineers practicing in Missouri are licensed by the Missouri Board for Architects, Professional Engineers, Professional Land Surveyors and Professional Landscape Architects. You can confirm a license number and its status in the board's public license search before you sign a contract.
Which building code applies in Missouri?
No statewide IBC/IRC; codes adopted by local jurisdictions (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
What site problems do engineers see most in Missouri?
Common issues include new Madrid Seismic Zone in the southeast (Bootheel), karst and sinkholes in the Ozarks, missouri and Mississippi River flooding and expansive clay soils.
