MAINTENANCE
IMMEDIATELY AFTER CONSTRUCTION, STABILIZE ALL DISTURBED AREAS WITH VEGETATION9.
CONDITIONS, PLACE IT IN THE UPPER SECTION OF THE APRON.
PREFERABLY STRAIGHT THROUGHOUT ITS LENGTH. IF A CURVE IS NEEDED TO FIT SITE
ENSURE THAT THE APRON IS PROPERLY ALIGNED WITH THE RECEIVING STREAM AND 8.
SLIGHTLY BELOW IT.
