FOLLOWING COMPLETION OF CONSTRUCTION OR DEVELOPMENT
7. REMOVE SEDIMENT FROM DETENTION POND AND RESTORE TO DESIGN DEPTHS.
8. MONITOR AND MAINTAIN THE INSTALLED EROSION CONTROL MEASURES
AND REPAIR AS NECESSARY.

NOTE:
ALL DITCH CONSTRUCTION MUST REMAIN ON THE PARKS LAND DEVELOPMENT
PROPERTY AND SHALL NOT DISTURB THE ADJOINING BANK OF THE DITCH.
UNDER NO CIRCUMSTANCES IS THE CONTRACTOR TO ENCROACH ON THE
ADJOINING PROPERTY WITH CONSTRUCTION OR EQUIPMENT.
SEEDBED PREPARATION
THE CONTRACTOR SHALL CUT AND DISPOSE OF WEEDS OR OTHER UNACCEPTABLE GROWTH ON THE AREAS
TO BE SEEDED. UNEVEN OR ROUGH AREAS SHALL BE SHAPED AND SMOOTHED TO PROVIDE FOR EFFECTIVE
SEEDING AND EASE OF MOWING. THE SOIL SHALL BE SCARIFIED TO A DEPTH OF NOT LESS THAN 5 INCHES.
CLODS SHALL BE BROKEN AND THE TOP 3-4 INCHES OF THE SOIL SHALL BE WORKED INTO A SEEDBED BY
THE USE OF PULVERIZERS, DRAGS, OR HARROWS. THE PREPARATION OF SEEDBEDS SHALL NOT BE DONE WHEN
THE SOIL IS FROZEN OR EXTREMELY WET.
LIMESTONE, FERTILIZER, AND SEED
LIMESTONE, FERTILIZER, AND SEED SHALL BE APPLIED WITHIN 24 HOURS AFTER COMPLETION OF SEEDBED
PREPARATION. LIMESTONE AND FERTILIZER MAY BE APPLIED AS PART OF THE SEEDBED PREPARATION, PROVIDED
IT IS WORKED INTO THE SOIL IF NOT SO APPLIED, LIMESTONE AND FERTILIZER SHALL BE DISTRIBUTED UNIFORMLY
OVER THE PREPARED SEEDBED AT THE SPECIFIED RATE OF APPLICATION AND THEN HARROWED, RAKED, OR
OTHERWISE THOROUGHLY WORKED INTO THE SEEDBED. SEED SHALL BE DISTRIBUTED UNIFORMLY OVER THE
SEEDBED AT THE RATE OF APPLICATION SPECIFIED, AND IMMEDIATELY HARROWED, RAKED, OR DRAGGED AS
TO COVER THE SEED NTH A LAYER OF SOIL.
MULCHING
ALL SEEDED AREAS SHALL BE MULCHED. GRAIN STRAW MAY BE USED AS MULCH AT ANY TIME OF THE
YEAR. MULCH SHALL BE APPLIED WITHIN 24 HOURS AFTER THE COMPLETION OF SEEDING. CARE SHALL
BE TAKEN AS TO PREVENT DISPLACEMENT OF SOIL OR SEED FROM THE SEEDBED AREA DURING MULCHING
OPERATIONS. MULCH SHALL BE UNIFORMLY SPREAD BY HAND OR MECHANICAL SPREADER. AN ACCEPTABLE
APPLICATION WILL BE THAT WHICH WILL ALLOW SOME SUNLIGHT TO PENETRATE AND AIR TO CIRCULATE BUT
ALSO PARTIALLY SHADE THE GROUND, REDUCE EROSION AND CONSERVE SOIL MOISTURE.
MAINTENANCE
AREAS WHERE SEEDING AND MULCHING HAVE BEEN PERFORMED SHALL BE MAINTAINED IN SATISFACTORY
CONDITION UNTIL ACCEPTANCE OF THE PROJECT BY THE OWNER. AREA OF DAMAGE OR FAILURE DUE TO ANY
CAUSE SHALL BE REPAIRED OR REDONE AS NECESSARY.

THE CONTRACTOR SHALL COMPLY WITH ALL APPLICABLE REQUIRMENTS OF THE EROSION
AND SEDIMENT CONTROL STANDARDS AND SPECIFICATIONS OF THE DEPARTMENT OF NATURAL
RESOURCES AND COMMUNITY DEVELOPMENT. SOIL EROSION AND SEDIMENTATION CONTROL
MEASURES SHALL BE PROVIDED ON ALL AREAS OF THE SITE WHICH ARE DISTURBED OR
GRADED. CONTRACTOR SHALL PROVIDE GROUND COVERS (SEE SCHEDULE BELOW) WITHIN 30
CALENDAR DAYS AFTER COMPLETION OF CONSTRUCTION WITHIN THE SPECIFIC AREAS. THE
CONTROL MEASURES SHALL BEGIN PRIOR TO ANY LAND DISTURBING ACTIVITY INCLUDING
CLEARING; SHALL CONTINUE DURING THE CONSTRUCTION AND SHALL CONTINUE PATH THE
NECESSARY MAINTENANCE UNTIL THE DISTURBED LAND IS STABILIZED. COMPLIANCE WITH LOCAL
AND/OR STATE SOIL EROSION AND SEDIMENTATION CONTROL LAWS SHALL BE THE ENTIRE
RESPONSIBILITY OF THE CONTRACTOR. THIS PARAGRAPH IS INTENDED TO SERVE ONLY AS A
GUIDE TO THE CONTRACTOR FOR COMPLIANCE NTH SUCH LAWS. ORDERS, RULES AND
REGULATIONS CONCERNING EROSION AND SEDIMENTATION CONTROL PROTECTION OF EXISTING
STRUCTURES AND FACILITIES FROM SEDIMENTATION SHALL BE THE RESPONSIBILITY OF THE
CONTRACTOR. ITEMS TO BE PROTECTED SHALL INCLUDE, BUT ARE NOT LIMITED TO CATCH BASINS,
