GRASSED SWALE NOTES:
1. EXCAVATE CHANNEL TO THE CROSS-SECTION SHOWN.
2. APPLY LIME, FERTILIZER AND SEED TO THE CHANNEL AND ADJOINING AREAS
IN ACCORDANCE WITH THE SEEDING SCHEDULE.
3. START LAYING THE NET FROM THE TOP OF THE UPSTREAM END OF THE
CHANNEL AND UNROLL IT DOWN THE GRADE. DO NO STRETCH MATTING.
4. BURY THE UPSLOPE END AND STAPLE THE NET EVERY 12" ACROSS THE TOP
END, EVERY 3' AROUND THE EDGES AND ACROSS THE MAT SO THAT THE
STRAW IS HELD CLOSELY AGAINST THE SOIL.
5. MATTING STRIPS SHOULD BE JOINED TOGETHER ALONG THE SIDES WITH A
3" OVERLAP AND STAPLED TOGETHER.
6. TO JOIN ENDS OF STRIPS, INSERT THE NEW ROLL OF NET IN A TRENCH AS
WITH UPSLOPE END AND OVERLAP IT 18" WITH THE PREVIOUSLY LAID UPPER
ROLL. TURN UNDER 6" OF THE 18" OVERLAP AND STAPLE EVERY
12" ACROSS THE END.
