Specifications include, but are not limited to: 4.2.1Roadside SprayingFurnish and apply by spraying glyphosate, a broad spectrum, non-selective systemic pre-emergent herbicide, to actively growing vegetation in Native Grass Seeding areas. Measure the rate of glyphosate with surfactant according to manufacturer’s label recommendations for controlling grass. Apply herbicide after the vegetation regrowth once the first mowing has reached boot to head stage of growth.First application: June 2020Subsequent Applications: Apply additional post-emergent herbicide in July 2020 to surviving vegetation with the exception of existing native grass.Method of Measurement: The quantity of Roadside Spraying for which payment will be made will be acres, void of living vegetation, shown in the contract documents unless changes have been authorized by the City Arborist. Basis of Payment: Pricing is requested as a firm-fixed price per occurrence, including all costs for labor, equipment, and materials for the first and subsequent sprayings to obtain a complete kill of all existing vegetation with the exception of existing native grass.4.2.2Clearing and GrubbingClear and grub designated trees. Clear volunteer vines at groundline and remove their branches from the existing trees. Clear all non-native trees, and clear and grub any stumps. Clear volunteer trees at groundline. Contractor shall remove and properly dispose of all debris from site, including existing piles of gravel, broken asphalt/concrete, and railroad ties. There is no location provided by the City to dump excess debris. This work shall be accomplished in July/August 2020.4.2.3Herbicide Application, Cut Stump – Summer 2020Include for cleared volunteer trees, shrubs and vines at the project location which cannot be grubbed out.Treatment is for use in wet or dry areas, or when stumps are initially cut to groundline. Stumps must be treated immediately after cutting. Cut stumps to ground line prior to herbicide application and brush away sawdust from the cut surface. All stumps shall be removed by the Contractor.Triclopyr herbicide shall be applied to stump within 5 minutes of cutting. Leave stumps without any additional cutting or grinding for 6 weeks after herbicide treatment to allow time for the herbicide to translocate.Use a water-based triethylamine salt formulation of triclopyr herbicide, labeled for use in and around standing water. Mix and apply the herbicide according to label directions for cut stump treatment. Apply the herbicide at 3 lbs/gal acid equivalent (ae) of triclopyr (for example, for 3 lbs ae/gal products apply undiluted). Apply the herbicide using a brush or directed spray, wetting the outer 2 inches of sapwood and the cambium (the tissue just inside of the bark), including the entire circumference and any torn bark areas. It is not necessary to treat the bark on the sides of the stump or exposed roots.Preapproved herbicide products:Triclopyr herbicide in a water-based formulation:Garlon 3AElement 3ATahoe 3A HerbicideEcotriclopyrDye: Hi-Light Blue
