Suggested Spacing
Primarily, the gradient of the slope will
determine the distance between SRFRs
on a slope, however, the soil type and
overall project risk may affect the final

Appropriate Applications
SRFRs are typically placed along the
toe, top, face and at grade breaks of
exposed and erodible slopes to shorten
the slope length and spread runoff as
sheet flow. SRFRs are also frequently
used for inlet protection, around tem-
porary stockpiles and even around the
perimeter of a job site. SRFRs are also
used in channel applications as checks
to reduce flow velocity and filter sedi-
ment laden flow. SRFRs may be used in
conjunction with Rolled Erosion Control
Products (RECPs) and Hydraulically Ap-
plied Erosion Control Products (HECPs).
If used with HECPs, SRFRs are installed
prior to application of the HECP. Once
SRFRs are installed, apply the HECP per
the manufacturer’s application rates
and instructions. When used with RECPs,
SRFRs are typically placed and secured
after installation of the RECP. Proper
installation is necessary for successful
SRFR implementation. Excessive runoff
and erosion may occur if SRFRs are not
adequately spaced, trenched in and/or
anchored. The following provides a gen-
eral guide to determination of spacing
and installation.
