Tamarisk (salt cedar) growth is pervasive throughout the disturbed areas, particularly on <br /> pit floors. <br /> Individual salt cedar plants will be cut as close to the ground as possible with chainsaws, <br /> and masticators, and herbicide such as Habitat, or equivalent, will be applied immediately <br /> thereafter to the perimeters of the cut stems. Approximately 12 acres (12 ac.) of <br /> tamarisk will require mastication and treatment. <br /> MEASUREMENT AND PAYMENT <br /> There will be no measurement for payment. Payment for this item will be reflected in a <br /> lump sum quote under Item 3.0 on the Bid Schedule. This lump sum quote will cover all <br /> costs for weed mowing and disposal including equipment, maintenance, and operator <br /> costs.

The work will involve <br /> cutting and removing fill from the slopes and backfilling to fill the gullies to 3H:1V slopes. <br /> Check dams will also be created with on-site material to slow the flow of water in the <br /> backfilled gullies. Approximately seven hundred fifty cubic yards (750 CY) of fill will be <br /> required to fill the erosion features. Fill will be obtained on-site. No imported material is <br /> required. <br /> MEASUREMENT AND PAYMENT <br /> There will be no measurement for payment.
