Vegetative and Fiber Mulch
716.01 DESCRIPTION. Furnish and place an approved vegetative or
fiber mulch with a tacking agent on seeded areas to promote seed germination and growth while temporarily protecting the soil from erosion.
716.02 MATERIALS. Mulching materials and tacking agents shall
comply with 1004.04 . Notify the engineer at least 7 calendar days in advance of commencing operations so that the mulch can be inspected and approved prior to use. Deliver vegetative and fiber mulch in bales or bags of uniform size. Store mulching materials in accordance with 106.09 . Protect mulch stockpiles from the weather.
716.03 GENERAL CONSTRUCTION REQUIREMENTS. Mulching
shall follow seeding operations within 48 hours. Do not spray mulch on structures. Remove all stains on structures and roadway appurtenances resulting from the mulch or the tacking agent; leave the surface in acceptable condition. During windy conditions, make adjustments in operation s to ensure uniform spreading. Repair damage to seeded areas and re-seed at no direct pay.
716.03.1 Tacked Vegetative Mulch : Distribute vegetative mulch
uniformly over the seeded area by blowing it simultaneously with an approved tacking agent. Space jet nozzles in the muzzle of the blower to provide a uniform coating of the mulch as it blows through the nozzles. The tacked vegetative mulch shall be loose enough to allow air to circul ate, but compact enough to partially shade the ground and reduce the impact of rainfall on the soil surface. Begin mulching at the top of the slopes and extend downward. Use blower pipe extensions where slopes cannot be reached by the blower.
716.03.2 Fiber Mulch: The application equipment shall have a built-
in agitation system with an operating capacity sufficient to agitate, suspend, and homogeneously mix the fiber mulch, water, and any tacking agent that is part of the fiber mulch system. Keep the fibers in uniform suspension throughout the mixing and distribution cycles. The slurry distribution lines Vegetative and Fiber Mulch

Payment will be made under: Item No. Pay Item Pay Unit 716-01 Mulch Ton Section 717 Seeding
717.01 DESCRIPTION. Prepare seed beds, furnish, and sow grass seed
on the areas designated on the plans or as directed. Unless otherwise specified, apply seed either mechanically in a dry condition under this section or with hydro -seeding equipment in accordance with Section 739 . Obtain the services of an established soil testing entity to coordinate soil sampling, perform testing and analyses, and prepare recommendations for materials and procedures to be used during the pre-planting phase of new turf establishment. When practical, perform soil testing early enough to permit agricultural lime or other additives (if required) to be applied sufficiently in advance of planting so that the soil pH adjustment will occur before planting. Test and analyze samples to determine pH and fertility conditions. Use the test results and recommendations to determine the quantities of agricultural lime and fertilizer required for pre-planting applications. Provide a copy of the test report with recommendations to the engineer. Testing will be at no direct pay. Consider probable time of application when making agricultural lime recommendations.
717.02 MATERIALS. Materials for seeding shall comply with the
following sections and subsections: Topsoil Section 715 Fertilizer 1004 .01 Agricultural Lime 1004.02 Seed 1004.03 Obtain water from any source. Do not use brackish, chemically contaminated, or oily water.
