Stormwater Inspection Load with stormwater inspection points of 18 locations: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop stormwater inspection points to 18 locations, then walk the calculation through step by step. Estimate stormwater inspection load from stormwater inspection points, average inspection time, and inspection window days.

The inputs for this scenario

  • Stormwater inspection points: 18 locations (the input this scenario stresses; the baseline uses 36)
  • Average time per inspection point: 0.45 hr / location (held at the documented default)
  • Compliance window: 5 days (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Stormwater Inspection Load = stormwater inspection points × average inspection time.
  • Stormwater Inspection Load works out to 8.1 hr at these inputs, and this is the headline figure for the scenario.
  • Stormwater inspection hours per day works out to 1.62 hr / day at these inputs.
  • Stormwater inspection point count works out to 18 locations at these inputs.
  • Average inspection time works out to 0.45 hr / location at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where stormwater inspection points sits at 36 locations and the headline result is 16.2 hr, this scenario comes in 50% below the baseline at 8.1 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to stormwater inspection points, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes every point takes the same average time and folds travel into that figure, so sprawling sites with long walks between points may need a higher per-point time.
