D. Seeding The CONTRACTOR shall be required to supply the seed. The seed mixture designated below shall be sown uniformly on the prepared seedbed. Seeding shall not be done if the ground is frozen. Some areas, such as rock outcrops, shrub or tree clumps, etc., within the work area limits are not designated to be seeded. These areas are identified in Exhibit 3. Drill Seedinq In all areas where practicable, seeding shall be performed with a grassland drill with depth bands and seedbox agitator and equipped with either packing wheels or a cultipacker. The drill shall be capable of properly handling the seed being planted on all slopes designated for this method. Seed shall be drilled on the contour. The distance between drilled furrows shall not be more than twelve (12> inches. Seed shall be planted one-quarter inch (1/4") to one-half inch (1/2"> deep. Broadcast Seeding Broadcast seeding may be used at the CONTRACTOR'S option, where drill seeding is not practicable due to excessive slope grade or excessively rocky soil. Regardless of the method used, broadcast seed shall be covered approximately one-quarter (1/4) to one-half (1/2) inch deep by flexible-tine harrowing or a similar method acceptable to the PROJECT MANAGER. If seed is broadcast, either a pneumatic seeder, a hydraulic seeder, or a hand or machine operated seeder capable of uniform application of prescribed quantities shall be used. Hydroseeding, if employed, shall be done prior to hydromulching, in a separate operation. All seeds shall conform to the current rules and regulations of the State of Colorado and the U.S. Department of Agriculture. Unless exception is granted by the PROJECT MANAGER, seed shall be thoroughly pre-mixed (except for legumes) in the required proportions and delivered to the work site in bags or containers clearly tagged showing the name and address of the supplier, the net weight of each species of seed in the mix, the percent of weed seed content, and the guaranteed percentage of purity and germination for each species furnished. The CONTRACTOR shall give the tags to the PROJECT MANAGER. The CONTRACTOR shall furnish a signed statement certifying that the seed furnished is from a lot that has been tested by a recognized laboratory for seed testing within nine months prior to the date of delivery to the job site. Legume seed shall be inoculated with the correct viable inoculant for the species. Outdated inoculants will not be accepted. Inoculating shall be done within 48 hours before seeding. -7-
