Debris and Drainage Conditions That Affect Runoff
Every structure experiences different patterns of runoff depending on surrounding conditions. Accumulations that affect drainage performance include:
- Dry leaves, twigs, and small branches settling in gutter channels.
- Organic silt, grit, and decaying plant matter forming dense blockages along trough seams.
- Windblown debris collecting around downspout openings and upper drop outlets.
- Restrictions at the ground level where downspout elbows discharge water onto the property.
