SILT FENCE MAINTENANCE STANDARDS:
1. ANY DAMAGE SHALL BE REPAIRED IMMEDIATELY.
2. IF CONCENTRATED FLOWS ARE EVIDENT UPHILL OF THE FENCE, THEY MUST BE INTERCEPTED AND CONVEYED TO \ \ \
A \
A SEDIMENT TRAP OR POND.
3. IT IS IMPORTANT TO CHECK THE UPHILL SIDE OF THE FENCE FOR SIGNS OF THE FENCE CLOGGING AND ACTING l F\ \ \ \
AS A BARFIER TO FLOW AND THEN CAUSING CHANNELIZATION OF FLOW PARALLEL TO THE FENCE. IF THIS 1�$
OCCURS, REPLACE THE FENCE OR REMOVE THE TRAPPED SEDIMENT. ELEV. 421.0'J
4. SEDIMENT MUST BE REMOVED WHEN THE SEDIMENT IS 6 INCHES HIGH.
5. IF THE FILTER FABRIC (GEOTEXTILE) HAS DETERIORATED DUE TO ULTRAVIOLET BREAKDOWN, IT SHALL BE
REPLACED.

a within a catch basin. All catch basins and conveyance lines shall be cleaned prior to
