A BETTER ENGINEERING WORKFLOWEverything in its place.
Everything in its place.
Nothing in your way.
Purpose-built for one SFWMD drainage basin, with shared inputs entered once and a clear path from project location to nutrient review.
Every area accounted for
Independent pre/post rows preserve individual acreage and low/high grading for later CN calculations.
Show the actual math
Our calculation engine will expose the equations, references, and TP/TN treatment ledger.
THE PROCESS
Six steps, one consistent workspace.
Follow the natural engineering sequence without switching tools or re-entering shared basin assumptions.

ENGINEERING FIRST
Confidence begins with traceable calculations.
We’re building around the June 2024 Florida ERP Applicant’s Handbook, SFWMD Volume II, Appendices M–O, and independently tested methods—not mysterious, uncheckable results.
- Separate Total Phosphorus and Total Nitrogen determinations
- Row-specific grading retained for soil storage and curve number
- Proper mass accounting for treatment in series and bypasses
- Clear PASS, FAIL, or REVIEW REQUIRED explanations
SIMPLE, TRANSPARENT PRICING
Your calculations are yours to review.
Once the calculation engine is validated, you'll be able to inspect project results free of charge. Pay only when you want the clean engineering PDF.
