College Baseball Field Grading Standards

Inquiry about standard slope requirements for college baseball fields.

Outfield Slope

• Minimum: 1% (1 inch per foot = 1 ft drop per 100 ft)
• Maximum: 2.5% (3.25 inches per foot)
• Direction: Away from diamond/infield

Three Acceptable Grading Patterns

1. Uniform slope from infield to outfield fence
2. Center ridge from 2nd base to center field, sloping to 1st/3rd base lines
3. Center high point at mid-center field with swale, gentle drop past 1st/3rd

Infield Grading (Skinned)

• High point: Pitcher's mound (7–8 inches above 1st/3rd base)
• Slope: 1% in all directions from mound
• Sub-drainage: Recommended throughout (often value-engineered out)

Multi-Use Recreation Fields

Constant cross-slope (1–2.5%) without pitcher's mound for mowing simplicity.
