Erosion Control
(OP)
Erosion control blankets are good to stabilize steep slopes to avoid runoff to natural areas. Are they needed in areas like steep slopes within a landfill or the slopes of the internal side of a detention pond, etc.?

Type 1 (cheap) is used to provide minimal erosion control and mostly helps the vegetation to become established. Seeding is required and the vegetation provides the erosion control. Hydroseed / hydromulch might be a good alternative.
Type 2 (expensive) is a turf reinforcement mat which provides considerable erosion control, even without any vegetation. Seeding and mulching are required.

But most of the time our clients do not maintain the slopes, do not irrigate the slopes, and we very rarely are dealing with non-erosive soils. So, unless you have a project with those unique characteristics, blanketing all soils steeper than 4:1 is a good practice.
