The Problem We're Solving

An Aging Infrastructure — and the Knowledge to Save It

Across the Midwest, decades of drainage infrastructure knowledge lives in the minds of a retiring generation of land managers. Tile lines, ditch routes, and district boundaries exist only on paper maps — fading, scattered, and undigitized.

Drainage USA captures that institutional knowledge in GIS before it's lost. We provide updated drainage maps. We combine field expertise with modern mapping technology to build comprehensive drainage inventories that serve counties, drainage districts, and developers for generations.

This is our mission. This is DrainageUSA.

What We Do

Six Core Services for Drainage Districts & Developers

Get a Quote

Drainage District Maps

We produce accurate, court-ready GIS maps of drainage district boundaries, asset locations, and jurisdictional limits. Ideal for commissioners managing annual inspections, maintenance schedules, and legal documentation requirements.

Drain Tile Investigation Reports

Field investigations and detailed written reports on existing tile networks — their condition, routing, and performance. Essential for land developers, drainage commissioners, and anyone troubleshooting wet field issues or planning new tile systems.

Map Archiving & Reformatting

We digitize and preserve aging paper maps, hand-drawn records, and historical drainage documents into clean, searchable GIS formats. Protect irreplaceable institutional knowledge before it deteriorates or disappears.

Ditch & Flooding Assessments

On-site evaluations of open ditch systems, flood-prone areas, and drainage capacity issues. We document conditions, identify problem points, and provide actionable recommendations for remediation or redesign.

Assessment Roll Reviews

Review Drainage District assessment roll to find holes in the taxing distributions and compare the real-time assessment roll with the county with the historical map. We can asssit with splits, combos and delivering data to the county for updates.

Digital GIS Maps

Interactive, web-accessible digital maps of your drainage assets — viewable in the field or the office. We build layered GIS datasets that integrate with your existing county or district systems for long-term usability and maintenance planning.

The Bigger Picture

Illinois Has Millions of Acres of Drainage Infrastructure That Nobody Has Mapped

Our work begins with Illinois, but the need spans the entire agricultural Midwest. Drainage enterprises — the networks of tile, ditches, and districts that keep farmland productive — are critically underdocumented. We're changing that, one county at a time.

Who You're Working With

Hi, I'm Patrick

I founded Agrowhere LLC after seeing firsthand how much critical drainage infrastructure knowledge was at risk of being lost — tucked away in aging paper maps and the memories of a retiring generation of land managers.

I work directly with drainage district commissioners, county officials, and land developers to build GIS maps that preserve that institutional knowledge and make it actionable. Every project I take on, I'm the person you're talking to — no middlemen, no handoffs.

If you want to see examples of my work or get testimonials from past clients, just reach out.
