Pond / SCM Geometry QC

Pond/SCM geometry QC: three checks against criteria you enter, one boundary pick.

Command VDCPONDQC · VDC QC tab › Design QC panel
Pond/SCM geometry QC: three checks against criteria you enter, one boundary pick.

What it does

  • Freeboard: top of bank vs design high water + required freeboard.
  • Side slopes: steepest interior H:1 inside the top-of-bank boundary vs your max.
  • Storage: computed volume below design high water vs required storage.
  • CSV + findings palette; the CSV documents the check for the submittal file.

Worth knowing

  • Geometry only, routing and outlet sizing are the engineer's calcs.
  • The boundary must be the top of bank; an outer easement line inflates storage.
  • Draft work product compared against criteria you enter, requires professional review.

When to use it

  • Before submitting the SCM - does the drawn pond hold what the calcs assumed.
  • After a bank regrade - did freeboard or storage move.

How to run it

  1. Run VDCPONDQC; pick the pond surface and enter design high water, freeboard, max slope, required storage.
  2. Pick the top-of-bank boundary polyline.
  3. Work the findings palette; the CSV documents the check for the submittal file.

Options

  • Criteria: design high water, required freeboard, max interior side slope (H:1), required storage - all user-entered.

Watch out for

  • Geometry QC only - hydrology/hydraulics (routing, outlet sizing) are the engineer's calcs.
  • The boundary polyline must be the top of bank - an outer easement line inflates storage.
  • Compares against criteria you enter - not a compliance determination.
