establishment period.

the first seeding, the Contractor shall reseed and care for thin spots until an even stand with

ninety-five percent (95%) coverage is produced.

Weed control herbicides, in addition to that which is specifically required elsewhere, may be

applied to planted areas at no expense to the Agency, if the Contractor deems it necessary.

The type of herbicide to be used and method of application shall be approved by the Agency.

Following the plant establishment period, the Contractor shall provide a warranty that

guarantees all trees for one (1) year from date of Final Acceptance. The Contractor shall

replace any tree that dies during the warranty period and the replacement shall be the same

size container as originally designated on the Plans.

20-4.08 Inspection for Plant Establishment Work

Upon completion of the planting work and irrigation installation, the Contractor shall notify

the Agency that the project is ready for maintenance. The Agency will then schedule a pre-

maintenance walk-through inspection and will notify the Contractor and the Landscape Architect

irrigation, turf, and planting work complete and in compliance with the Contract, the Agency will

authorize the start of the plant establishment period. Written notice will be given to the

Contractor by the Agency as to the starting date of the plant establishment period.
