1. BEGIN AT THE LOCATION WHERE THE WATTLE IS TO BE
INSTALLED BY EXCAVATING A 2-3" DEEP BY 9" WIDE
TRENCH ALONG THE CONTOUR OF THE SLOPE.
EXCAVATED SOIL SHOULD BE PLACED UP-SLOPE FROM
THE ANCHOR TRENCH.
2. PLACE THE WATTLE IN THE TRENCH SO THAT IT
CONTOURS TO THE SOIL SURFACE. COMPACT THE SOIL
FROM THE EXCAVATED TRENCH AGAINST THE WATTLE ON
THE UPHILL SIDE. ADJACENT WATTLES SHOULD TIGHTLY
ABUT.
3. SECURE THE WATTLE WITH 24" LONG STAKES EVERY
3-4' WITH A STAKE ON EACH END. STAKES SHOULD
BE DRIVEN THROUGH THE MIDDLE OF THE WATTLES
LEAVING 2-3" OF STAKE EXTENDING; ABOVE. THE
WATTLE STAKES SHOULD BE DRIVEN PERPENDICULAR TO
THE SLOPE FACE.
4. SECURE WATTLES PLACED ON PAVED SURFACES WITH
SANDBAGS SPACED AT AN INTERVAL. SUFFICIENT TO

WATER QUALITY BASIN SHALL BE INSPECTED AT LEAST TWICE ANNUALLY AND AFTER ALL MAJOR STORMS TO ENSURE THAT IT IS
OPERATING AS INTENDED, PRETREATMENT BMP'S SHALL BE INSPECTED AND CLEANED DURING THE REGULAR Bi -ANNUAL INSPECTIONS.
POTENTIAL PROBLEMS THAT SHOULD BE CHECKED INCLUDE:
PONDING
EROSION
CLOGGING OF INLET AND OUTLET PIPES
ANY NECESSARY REPAIRS SHALL BE MADE IMMEDIATELY, TRASH SHALL BE REMOVED AND THE BANKS, OF BASINS, MOWED AT LEAST
TWICE PER YEAR. (MOWING SHOULD BE PERFORMED WHEN GROUND IS DRY TO AVOID RUTS AND COMPACTION) SEDIMENT' SHALL BE
REMOVED FROM THE BASIN AND PRETREATMENT AREA AS NECESSARY, AND AT LEAST ONCE EVERY FIVE YEARS.
RECORD KEEPING
RECORDS SHALL BE MAINTAINED BY THE OWNER AT THEIR OFFICES & SHALL DOCUMENT ALL ROUTINE & EMERGENCY MAINTENANCE
WORK PERFORMED TO THE STORMWATER MANAGEMENT SYSTEM & SHALL BEAR THE SIGNATURE OF THE INDIVIDUAL SUPERVISING THE
