            "text": "This is a HydroCAD routing diagram titled \"WQ\", part of \"Routing Diagram for 102 Sams -REV 12-02-25\", prepared by Haler Consulting and printed 04/12/2025 (software footer: HydroCAD 10.20-2h, s/n 10351, © 2024 HydroCAD Software Solutions LLC). It shows two separate water-quality drainage networks, each with two subcatchments draining into one infiltration basin. The arrows show the direction of flow.\n\nLeft network: Subcatchment 171S, labelled \"DA P1 (Impervious)\", sits at lower left and has an arrow running rightward to pond 174P, labelled \"WQ Infiltration Basin #1\". Subcatchment 173S, labelled \"DA P4 (Pervious)\", sits above and to the left and has a diagonal arrow running down and to the right into the same pond 174P.\n\nRight network: Subcatchment 176S, labelled \"DA P3 (Pervious)\", sits at upper right and has a diagonal arrow running down and to the left into pond 177P, labelled \"WQ Infiltration Basin #2\". Subcatchment 175S, labelled \"DA P2 (Impervious)\", sits at lower right and has an arrow running leftward into the same pond 177P.\n\nThe two networks do not connect to each other. Each pond is a terminal point; no arrow leaves either basin. The page has a legend along the bottom left showing the symbols: Subcat (green hexagon), Reach (orange rectangle), Pond (blue triangle), and Link (red irregular shape). The legend and the title block sit outside the flow itself. The top half of the page is blank.",
