Stabilization Measures
Disturbed Area
Introduction
Stabilization measures reduce erosion, increase infiltration,
slow the flow of water, and minimize raindrop impact of
disturbed areas during and after construction activities.
Stabilization measures can be temporary or permanent
depending on their type and application. Disturbed areas that
will remain inactive for 14 or more days are required to be
stabilized.
Applicable Local Requirements
1. Stabilize disturbed areas
Approved Options
1. Surface Roughening: Consists of 3” minimum depressions
running perpendicular to slopes using equipment, such as
a grouser or sheep’s foot.
2. Crimped Straw Mulch: Consists of weed-free straw with a
12” minimum length evenly distributed at a rate of 4000
lbs/acre and crimped into the soil. Straw blowers and hand
broadcasting are useful distribution methods. Flat shovels
and disc plows work well for crimping.
3. Wood Mulching: Consists of shredded wood and compost
evenly distributed. Apply wood mulch and compost to a
depth of 2”-3”.
4. Rolled Erosion Control Products: Consists of biodegradable
blankets composed of fibers such as jute, straw, coconut,
or a combination of straw and coconut fibers. Installation
criteria to consider include anchor slots, overlapping
adjacent blankets, check dams, and staking. See page 36
for an installation specification
5. Sod: Immediately stabilizes disturbed areas. Consider sod
type, soil preparation, soil amendments, and irrigation
until establishment
6. Hydro-Seed: Consists of wood mulch, tackifier/binder, and
seed sprayed by machine or hand depending on the
application and area. Hydro-seed immediately stabilizes
barren ground and can be used in temporary or
permanent applications.
