CONTROL NOTES:
1. Sediment control devices and structures shall be installed,
maintained and amended as needed to provide effective
control of accelerated sedlmentation until the contributing
watersheds are stabilized.
2. Construction Seems
A Notify Engineer, Owner and Land Quality Section prior
to beginning construction.
B. Install stabilized construction entrances.
C. Silt fence and temporary diversion berms shall be Installed at edge of clearing, an all
down slopes Immediately after area Is cleared. sit fence and temporary diversion berms
shall be maintained until the arse is stabilized competely.
D. Construct drainage *wales and sediment storage devices. Install
storm drainage piping.
E. Immediately seed, mulch and Install Ilnsrs.
F. Maintain erosion control meaares as needed to assure
full functionobility.
G. Place CABC over compacted subgrade. Install asphalt
surface course.
H. Reseed and mulch shoulders and ditches. Install liners an
all swaks (and provide ground cover an all exposed slopes.)
1. Seed• fertilize, mulch or otherwise stabilize all disturbed areas within 21
days of completing any phose of the grading work.
3.
Apply line and fertilizer and work Into 4-6 Inches of soil. Seed
mixture shall be distributed uniformly and covered with a dean
straw mulch. All mulch shall be crimped or asphalt tacked to help
