Know the Terrain
Before You Arrive.
Drainage Intelligence Reports™ give contractors, inspectors, and landscapers terrain-based drainage data before the first site visit — powered by USGS LiDAR and delivered in 24 hours.
Low Point Convergence Analysis™ is the proprietary methodology developed by Low Point Labs to map drainage pathways, convergence zones, and likely accumulation areas on residential properties.
The Professionals Who Win Are the Ones Who Show Up Prepared
Terrain tells a story that most professionals never see until they're on site. Get the full drainage picture before your boots hit the ground.
Contractors who include terrain-based drainage data in proposals demonstrate deeper property understanding — leading to stronger bids and fewer change orders.
Know where water flows, collects, and concentrates before you arrive. Pre-visit terrain data eliminates guesswork and helps you show up knowing exactly where to look.
Most contractors and inspectors don't offer terrain-based analysis. Adding drainage intelligence to your services sets you apart in competitive markets.
"The best professionals don't guess about drainage — they show up with the data. The terrain tells the story. We help you read it first."
The View That Matters
Your property looks different through the lens of terrain science. LPCA™ analyzes elevation data to map flow paths, convergence zones, and ponding potential not visible from above.

What is Low Point Convergence Analysis™?
Low Point Convergence Analysis™ (LPCA™) is the terrain analysis methodology developed by Low Point Labs to model how water naturally moves across residential landscapes. By analyzing elevation patterns, drainage convergence, watershed behavior, and structure proximity, LPCA™ helps screen for where runoff is likely to travel, collect, and interact with the property.
Terrain Slope Modeling
Models how water flows downhill across the property based on surface elevation.
Drainage Convergence Mapping
Maps areas where runoff paths come together and intensify.
Watershed Pattern Analysis
Shows how surrounding terrain influences water movement onto and across the site.
Structure Proximity Review
Highlights drainage behavior that may affect areas near the home and nearby structures.
Three Steps to Drainage Clarity
No site visit required. No scheduling delays. Enter an address and get actionable drainage intelligence derived from the same elevation data used by civil engineers.
Enter Your Address
We verify high-resolution LiDAR coverage for your property and retrieve parcel boundaries and elevation data automatically.
We Analyze the Terrain
Our system processes 1-meter resolution elevation data to model surface flow, map drainage paths, and screen for potential ponding zones across your parcel.
Review Your Report
Within 24 hours, receive an expert-reviewed drainage screening report with annotated maps, areas of interest, flow analysis, and recommended areas for closer inspection.
What the Report Shows
Each report delivers a multi-layered drainage screening based on the actual topography of your specific property — not generic neighborhood data.
Surface Flow Direction
Mapped water runoff paths across the property based on steepest-descent analysis of the terrain surface.
Ponding Potential Zones
Topographic depressions and low-lying areas where water is likely to collect after rainfall events.
Drainage Pattern Assessment
Full watershed delineation with classified drainage channels showing primary and secondary flow networks.
Contour Analysis
High-resolution contour mapping that shows grading patterns, slope transitions, and terrain irregularities.
Building Proximity Review
Analysis of flow paths and accumulation zones relative to building footprints on the property.
Annotated Site Exhibit
Professional map exhibit with labeled features, annotations, and clear visual indicators for each identified area.
An Added Layer of Review — Not a Replacement
This is a screening tool designed for early awareness. It highlights where terrain may direct water — not where problems definitively exist. Many flagged areas may already have drainage solutions in place. This report helps you know where to look closer and what questions to ask during inspections. It does not replace professional engineering assessments, soil analysis, or on-site evaluations.

Common Questions From Professionals
"I already do site visits — why do I need this?"
You'll still visit. This gives you the full topographic picture before you arrive, so you show up knowing where to focus. Subtle grade changes of 2–3 inches can redirect hundreds of gallons — LiDAR data shows what the eye cannot.
"My clients don't ask for this."
The best professionals don't wait to be asked. Including terrain-based drainage data in your proposal sets you apart before the client knows to ask for it. It demonstrates expertise and builds immediate credibility.
"How does this help me win more work?"
Show up with annotated terrain maps and flow analysis in your proposal. Clients hire the professional who demonstrates they understand the property — not the one who says "I'll take a look and get back to you."
"What about volume pricing?"
Bulk credits are available for professionals running multiple reports. Volume discounts start at 5-packs and increase at 10 and 25. Credits are redeemed from your dashboard and never expire.
