Table 2. Timeline for Implementing Maintenance
Condition
Timeframe for Implementation
Maintenance of surface
roughening (SR)
In areas not seeded and mulched after surface
roughening, surfaces shall be re- roughened as
necessary to maintain groove depth and smooth
over rill erosion.
Maintenance of mulch (MU)-
crimped straw or hydro -mulch
Areas where erosion is evident shall be repaired and
additional mulch re- applied. If either the crimped
straw or hydro -mulch was applied as a stand -alone
erosion control measure (i.e., no temporary
vegetative cover was seeded), the area will need to
be monitored and the reapplication of either
crimped straw mulch or hydro -mulch may be
required to maintain effective soil stabilization over
the disturbed area.
Maintenance of mulch (MU)-
straw with tactifier
Areas where erosion is evident shall be repaired and
additional mulch re- applied. If the straw was
applied as a stand alone erosion control measure
(i.e., no temporary vegetative cover was seeded),
the area will need to be monitored and the
reapplication of straw mulch and tactifier may be
required to maintain effective soil stabilization over
the disturbed area.
Maintenance of mulch (MU)-
wood
Areas where erosion is evident shall be repaired and
additional mulch re- applied. Reapplication of the
wood mulch may be required to maintain effective
soil stabilization over the disturbed area.
