TEMPORARY EROSION/
SEDIMENTATION CONTROL NOTES
1. THE TEMPORARY SILTATION FACILITIES SHALL BE CONSTRUCTED AS DETAILED.
2. WHERE POSSIBLE, MAINTAIN NATURAL VEGETATION FOR SILT CONTROL.
3. TEMPORARY SILTATION AND DETENTION PONDS WILL BE CONSTRUCTED BY STRAW(HAY)
BALES AROUND SWALES OR SHALLOW CUTS AS SHOWN.
4. ALL TEMPORARY SILTATION PONDS SHALL BE MAINTAINED IN A SATISFACTORY CONDITION
UNTIL SUCH TIME THAT CLEARING AND/OR CONSTRUCTION IS COMPLETED AND PERMANENT
DRAINAGE FACILITIES ARE OPERATIONAL.
5. RIP -RAP BASE (BOTH SIDES) OF STRAW BALES FOR EROSION AND SILTATION CONTROL
AS MAY BE REQUIRED.
6. RETURN SILTATION AREAS TO ORIGINAL CONDITION OR BETTER IF SUCH AREAS ARE
CONSIDERED IN THE PROPOSED DEVELOPMENT.
7. APPROVAL OF THIS PLAN IS SOLELY FOR THE TEMPORARY SEDIMENTAION CONTROL PLAN
AND IS NOT APPROVAL OF DESIGN, LOCATION OR SIZE OF PIPES, RESTRICTORS,
CHANNELS OR RETENTION FACILITIES.
