PERMA NEN T SEEDING
DEFINITION
§e—eding disturbed areas with perennial grasses and (or) legumes to provide a
permanent vegetative cover to lessen runoff and soil erosion.
PURPOSE
To lessen soil erosion and permanently stabilize disturbed areas created by
_grading of construction sites.
CONDITIONS WHERE PRACTICE APPLIES
All bare soil areas on construction sites which are not covered by structures
or other erosion control devices.
PREPARATION
Prepare seedbed by ripping, chiseling, harrowing or plowing to depth of six
inches so as to produce a loose, friable surface. Remove all stones,
boulders, stumps or debris from the surface " which , would prohibit germination
or plant growth. Spread topsoil in a layer J — 6' depth.
Incorporate into the soll 800 to 1,000 pounds of 10-10-10 fertilizer plus 500
pounds of twenty percent (20Z) superphosphate per acre and two tons of
dolomitic lime per acre unless soil tests indicate that a lower rate of lime
can be used.
Mulch after seeding with 1.5 tons of grain straw per acre and either crimp
straw into soil or tack with liquid asphalt at 400 gallons per acre or
emulsified asphalt at JOO gallons per acre.

GENERAL EROSION CONTROL NOTES
THE CONTRACTOR SHALL TAKE ALL REASONABLE PRECAUTIONS TO AVOID THE SILTING OF
STREAMS, LAKES OR OTHER WATER COURSES DUE TO THE CCNSTRUCTION OF THIS PROJECT,
EFFECTIVE EROSION CONTROL MEASURES SHALL BE INITIATED PRIOR TO THE COMMENCEMENT
OF CLEARING, GRADING, EXCAVATION, OR OTHER OPERATIONS THAT WILL DISTURB THE NATURAL
PROTECTION. THE EROSION CONTROL DETAILS SHOWN HEREIN ARE FOR THE CONTRACTOR'S
REFERENCE. THE DETERMINATION OF WHICH DETAIL IS APPLICABLE AS THE WORK PROGRESSES
SHALL BE AS SHOWN ON THE PLANS OR MADE BY THE ENGINEER.
ALL DITCHES SHALL BE STABILIZED AS SOON AS IS PRACTICABLE TO MINIMIZE EROSION.
THE CONTRACTOR IS REFERRED TO THE DETAILED SPECIFICATONS FOR A DESCRIPTION OF ADDITIONAL
EROSION CONTROL REQUIREMENTS,
THE CONTRACTOR SHALL MAINTAIN ALL EROSION CONTROL DEVICES IN A GOOD, WORKING STATE OF
REPAIR UNTIL THEIR USE IS NO LONGER WARRANTED, AT THAT TIME, THE EROSION CONTROL DEVICES
SHALL BE REMOVED AND DISPOSED OF SO AS TO CAUSE NO STREAM SILTATION.
WHERE CULVERT PIPES ARE TO BE INSTALLED UNDER ROADWAYS, THE CONTRACTOR SHALL INSTALL THE
CULVERTS AS RAPIDLY AS IS PRACTICAL, BACK FILL IMMEDIATELY AND RIP RAP THE UPSTREAM AND
DOWNSTREAM SIDES OF THE STREAM CHANNEL,
