            "text": "This is a HydroCAD routing diagram titled \"County Analysis\", showing how stormwater flows through a small network. At the upper centre is a green hexagon, the subcatchment labelled \"35S\", with the label \"COUNTY SYSTEM\" printed beneath it. A single dark blue line runs straight down from the bottom of the hexagon to a small downward-pointing arrowhead just above a light blue triangle, the pond labelled \"CB-1\". The arrow shows that runoff from subcatchment 35S drains into pond CB-1. Beneath the triangle is the caption \"County Basin-1\". The connector is a single arrow with no label. Pond CB-1 has no outgoing connector, so the flow ends there.\n\nA legend in the lower left shows four symbols: a green hexagon for Subcat, an orange rectangle for Reach, a blue triangle for Pond, and a red-outlined jagged shape for Link. The legend sits outside the flow. In the lower right is a title box reading \"Routing Diagram for Analysis - County, Prepared by Civil Core Consulting, Printed 10/24/2025, HydroCAD® 10.20-7a s/n 13637 © 2025 HydroCAD Software Solutions LLC\". This box is also outside the flow.",
