I’m requesting an enhancement to the Curve Number (CN) workflow in InfoDrainage to better support regulatory review and auditability of SCS runoff calculations. Current behavior: users can manually enter a pervious Curve Number via the Curve Number Calculator (selecting Land Use, Cover Type, Condition, and Soil Group) or derive CNs from Land Use/Soil Type layers. Requested enhancements: 1) Persist Manual Calculator Inputs — when a user selects Land Use, Cover Type, Condition, Soil Group, and pervious CN in the Curve Number Calculator, save those selections as catchment attributes (not just the computed CN). 2) Include Inputs in Reports — add the saved calculator fields to standard report templates and Flexible Reporting so printed and exported reports list: Land Use, Cover Type, Condition, Soil Group, Pervious CN, PIMP, PACN, and Composite CN where applicable. 3) Optional Detail/Log Output — provide an optional “CN derivation detail” report that shows whether the CN was derived from a layer lookup or manually entered, and records the exact lookup table or manual selections
