Erosion control methods should be appropriate for the size of site, the
duration of construction and the slope, length and grade. Soil stabilization
with vegetative cover is generally the most effective stabilization.
Hydroseeding with mulch application or periodic hydromulching may be used
for soil stabilization alone on slopes flatter than 3:1. When hydroseeding does
not produce dense vegetation, areas should be re-seeded periodically until
growth occurs or if short duration summer stabilization is required and
hydroseeding should be supplemented with heavy hydromulching. For steep
slopes and drainage ways, erosion control blankets or gypsum-plaster may
be more appropriate.
