Design Criteria.
Drain Start pulls flood zones, base flood elevations, water tables, and local design standards into one dashboard — in minutes, not hours. Built by civil engineers, for civil engineers.
Before you can design,
you need the data.
And the data is everywhere.
Before a civil engineer can run a single calculation, they must gather mandatory design parameters scattered across multiple government sources, PDFs, and portals — with no single tool to consolidate them.

One address. All the criteria.
Drain Start consolidates data from FEMA, county records, municipal codes, and local standards — so you don't have to.
Just type the address. Drain Start automatically identifies the county, city, and applicable jurisdiction — no manual selection required.
FEMA FIRM Maps, county records, municipal codes, and property appraiser — queried simultaneously in under 30 seconds.
Flood zone, BFE, freeboard, water table, design storm criteria, and drawing standards — in a single panel, ready to use.

Every parameter.
One search. One panel.
All design parameters are sourced from official government and municipal databases.
