TEMPORARY NON LAWN SEEDING MEASURES

A. GENERAL:

1. AFTER CONSTRUCTION IS COMPLETE IN ANY AREA OR PHASE OF THE PROJECT, THE

DISTURBED AREAS SHALL RECEIVE A PERMANENT GROUND COVER. SEEDING AND

MULCHING SHALL BE PERFORMED IMMEDIATELY BEHIND CONSTRUCTION. THE

CONTRACTOR SHALL PROVIDE PERMANENT SEEDING IN ALL DISTURBED AREAS AS

INDICATED IN THE CONTRACT DOCUMENTS. THE CONTRACTOR SHALL ADAPT

PERMANENT SEEDING OPERATIONS TO PROTECT AND TO ACCOMMODATE ANY

TEMPORARY SEEDING AND SOIL AND EROSION CONTROL MEASURES THAT MAY

ALREADY BE IN PLACE DURING THE WORK PERIOD.

2. WHEN SEEDING MUST TAKE PLACE OUT OF SEASON FOR PERMANENT GRASS THE

APPROPRIATE TEMPORARY SEEDING SHALL BE DONE AND THE CONTRACTOR SHALL

BE RESPONSIBLE FOR PERMANENT SEEDING AS SPECIFIED IN SEASON AT NO

ADDITIONAL COST TO OWNER.

3. CONTRACTOR SHALL BE RESPONSIBLE FOR TURF MAINTENANCE THROUGH

SUBSTANTIAL COMPLETION. SLOPES MUST BE AT 90% COVERAGE AT SUBSTANTIAL

COMPLETION REVIEW TO BE ACCEPTED. IF NOT AT 90% COVERAGE, SUBSTANTIAL

COMPLETION WILL BE DELAYED UNTIL 90% COVERAGE IS ACHIEVED AND/OR UNTIL

THE FOLLOWING GROWING SEASON.

B. SITE PREPARATION AND INSTALLATION:

1. GROUND COVER: ALL DISTURBED AREAS SHALL BE DRESSED TO A DEPTH OF SIX (6)

INCHES. THE TOP THREE (3) INCHES SHALL BE PULVERIZED TO PROVIDE A UNIFORM

SEEDBED. RAKE OR HARROW THE SITE TO ESTABLISH A SMOOTH AND LEVEL FINAL

GRADE. SOIL PARTICLES SHOULD BE NO LARGER THAN MARBLE SIZE, AND PEA

GRAVEL SIZE IS EVEN BETTER. AGRICULTURAL LIME SHALL BE APPLIED AT THE

RATE OF 1 TONS/ACRE IMMEDIATELY BEFORE PLOWING. GRASS SEED SHALL BE

APPLIED AT THE RATES OUTLINED IN TABLES 2A AND 2B.

2. 10-10-10 FERTILIZER SHALL BE APPLIED TO ALL DISTURBED AREAS AT A RATE OF

750 LBS./ACRE. MULCHING SHALL CONSIST OF SMALL GRAIN STRAW APPLIED AT A

RATE OF 2 TONS/ACRE. MULCHED AREAS SHALL BE TACKED WITH ASPHALT OR

OTHER APPROVED METHOD SUFFICIENT TO HOLD THE STRAW IN PLACE, AT A RATE

OF 150 TO 200 GALLONS PER TON OF STRAW.

3. SOME AREAS MAY REQUIRE TEMPORARY SEEDING DUE TO AN INTERRUPTION OF

WORK OR SEASONAL RESTRICTIONS AS SPECIFIED IN THE PERMANENT SEEDING

SCHEDULE, OR A COMBINATION THEREOF. THESE AREAS SHALL BE RE-SEEDED IN

ACCORDANCE WITH THE PERMANENT SEEDING SCHEDULE. IF TEMPORARY

SEEDING IS REQUIRED DUE TO CONTRACTOR DELAYS, THERE WILL BE NO

COMPENSATION FOR THE TEMPORARY SEEDING. TEMPORARY SEEDING SHALL BE

PERFORMED ONLY AT THE DIRECTION OF THE ENGINEER OR INSPECTOR.

C. CLEANUP AND INSPECTION:

1. UPON COMPLETION OF WORK, THE CONTRACTOR SHALL REMOVE FROM THE SITE

ALL EQUIPMENT AND OTHER ARTICLES USED. ALL EXCESS SOIL, STONE, AND

DEBRIS SHALL BE REMOVED AND LEGALLY DISPOSED OF AT NO ADDITIONAL COST

TO THE OWNER. ALL WORK AREAS SHALL BE LEFT IN A CLEAN AND NEAT

CONDITION. ALL DAMAGE TO EXISTING CONSTRUCTION CAUSED BY LANDSCAPING

OPERATIONS SHALL BE REPAIRED TO THE SATISFACTION OF THE TOWN AT THE

CONTRACTOR'S EXPENSE.

2. SEEDED AREAS SHALL BE PROTECTED AND REPLANTED AS NECESSARY TO

ESTABLISH A UNIFORM STAND OF SPECIFIED GRASS. SCATTERED BARE SPOTS,

NONE OF WHICH SHALL BE LARGER THAT ONE (1) SQUARE FOOT, WILL BE ALLOWED

UP TO A MAXIMUM OF 3% OF THE SEEDED AREA FOR EACH PROPERTY. WHEN

SEEDED AREAS ARE READY FOR INSPECTION, THE MAINTAINED TURF AREAS SHALL

BE NEATLY MOWED TO THE UNIFORM HEIGHT OF APPROXIMATELY TWO AND

ONE-HALF (2.5) INCHES. THE LAWNS SHALL BE CONSIDERED ESTABLISHED ONLY

WHEN THE SPECIFIED GRASS IS VIGOROUS AND GROWING WELL IN ADDITION TO

MEETING THE OTHER REQUIREMENTS SPECIFIED.

GENERAL EROSION CONTROL NOTES

1. THE CONTRACTOR SHALL INSTALL ALL EROSION AND SEDIMENTATION CONTROL MEASURES AND
