GENERAL CONDITIONS

When possible, Contractor shall utilize equipment having low unit pressure ground contact within planting areas. Unless otherwise approved by the Engineer, the use of heavy equipment shall not be allowed in areas designated as “remnant” on the Plans. Contractor shall take precautions to ensure that equipment and vehicles do not damage the grading, utilities, structures, or existing trees and shrubs during planting operations. Any damage shall be repaired by the Contractor at no additional cost.

The capacity of the equipment shall be sufficient to perform the work and in the time period as specified herein, and as approved by the Engineer.

Off-road vehicles shall be equipped with off-road or high flotation tires that allow the vehicle to travel in soft roadside conditions. If the off-road vehicles are not equipped with appropriate tires for site conditions, the job will be postponed until the equipment can travel the roadside areas without rutting and getting stuck with no extra working days rewarded to the Contractor.

The tank on all spray equipment shall be equipped with tight-fitting lids which will prevent the contents from splashing or spilling out. Spray mixture tanks shall have sight gauges calibrated in English units for easy measurement, and mechanical or by-pass agitation systems to ensure thorough and continuous mixing of the chemicals. Pumps shall be capable of delivering 30 GPA at or around 40 PSI, and to keep the spray pattern full and steady without pulsation. Spray nozzles shall be selected which are designed to reduce potential herbicide drift.

The Contractor will be required to have all equipment cleaned and in proper working order before starting the job. An inspection of on-road, off-road, and hand-spray units will be completed by the Engineer prior to starting any work. If equipment is not clean or working properly, the Contractor will be required to fix the problem prior to starting the contract. The Contractor will be required to demonstrate the calibration of their equipment up to forty-eight (48) hours prior to the time of spraying operations are to begin.

Prior to starting herbicide work, the Contractor shall furnish Illinois Pesticide ID Cards (signed and dated) to the Engineer as visual proof that all personnel on the job are licensed Applicators or Operators by the Illinois Department of Agriculture, Bureau of Environmental Programs under the provisions of the Illinois Pesticide Act. The Illinois Department of Agriculture Aquatics license will be required of the person on site supervising the Operators on using pesticides in standing or running water. The Engineer shall record in the project records books the name and license number of each person. If the personnel on the job do not have the proper license, the job will be postponed until personnel who carry the proper license are on the job, with no extra working days awarded to the Contractor.

Herbicide spraying will not be allowed when temperatures exceed 85°F or are under 45°F, when wind velocities exceed ten (10) miles per hour, when foliage is wet or rain is eminent, when visibility is poor, or during legal holiday periods unless prior approval is received from the Engineer. There shall be no spraying during periods of rainfall and spraying shall be halted, in accordance with the herbicide manufacturer’s instructions, prior to periods of rainfall. Spraying shall be in accordance with the applicable portions of Section 107 of the Standard Specifications.

Within 48 hours of the application of herbicides, the Contractor shall complete and return to the Engineer, IDOT Operations form “OPER 2720”, Pesticide Application Daily Spray Record.

Chemicals used will have the lowest environmental impact for the task at hand. Organic or cultural practices will be used whenever practical. Within designated herbicide spray areas that receive foot traffic the Contractor will post marker signs immediately prior to application of herbicide products at the usual point or points of entry. The marker signs shall consist of a four inch by five-inch (4” x 5”) sign, vertical or horizontal, attached to the upper portion of a dowel or other supporting device with the bottom of the marker extending no less than twelve inches (12”) above the ground. Signs must be visible, if obstructed by taller vegetation a larger supporting device shall be used. The marker sign shall have a white background, and the lettering shall be in a contrasting color. The Marker sign shall state on one side, in letters of not less than three-eighths of an inch (3/8”), the following: “HERBICIDE APPLICATION – STAY OUT UNTIL DRY – FOR MORE INFORMATION CONTACT: (here shall be inserted the name and business telephone number of the applicator for hire).”

PLANTING TIME FRAME

Native seeds shall be planted during the following timeframe, the site preparation timeline detailed below shall be constructed based on an appropriate seeding timeframe:

Fall Planting: September 15th – November 30th

Extensions for planting timeframe are not expected to be granted for this project, to attain appropriate seed stratification the Department desires a fall installation. Minor extensions may be possible due to extenuating circumstances at the Engineers discretion and based on time of year, weather, and site conditions.

LAYOUT

The Department shall be responsible for the layout of planting areas.

SITE PREPARATION

Eleven (11) weeks prior to the targeted seeding date, the Department will mow all proposed wildflower seeding areas to a height of four to six inches (4-6”).

Seven (7) weeks prior to the targeted seeding date, conduct the initial Spot Spray application, including limited spot applications of the Milestone or equal + Transline or equal herbicide mixture utilized on existing hard-to-control and/or Roundup resistant weed species within the planting areas identified for non-selective herbicide application and within existing native grass stands.

Species targeted for spot applications are mainly teasel, thistle, wild parsnip, and others as identified by the Engineer.

Seven (7) weeks prior to the targeted seeding date, conduct the initial Pistol Spray application.

Cattails or Phragmites growing within planting areas identified for non-selective herbicide application shall be treated with an application of the Roundup Custom or equal herbicide mixture resulting in a complete kill of all existing vegetation. Spraying of herbicide with a pistol-style hose and reel sprayer and/or backpack sprayers is acceptable under these conditions; precautions shall be taken to eliminate damage to non-target areas from overspray.

Seven (7) weeks prior to the targeted seeding date, conduct initial Non-Selective Broadcast Spray application. Planting areas identified for non-selective herbicide application shall be treated with an application of the Roundup Custom or equal herbicide mixture resulting in a complete kill of all existing vegetation. Broadcast or “Boom” spraying of herbicide is acceptable under these conditions; precautions shall be taken to eliminate damage to non-target areas from overspray.

Three (3) weeks prior to the targeted seeding date, conduct a follow-up Pistol Spray application.

Cattails or Phragmites growing in the bottom of drainage ditches within planting areas identified for non-selective herbicide application shall be treated with an application of the Roundup Custom or equal herbicide mixture resulting in a complete kill of all existing vegetation. Spraying of herbicide with a pistol-style hose and reel sprayer and/or backpack sprayers is acceptable under these conditions; precautions shall be taken to eliminate damage to non-target areas from overspray.

Three (3) weeks prior to the targeted seeding date, conduct a follow-up Non-Selective Broadcast Spray application. Planting areas identified for non-selective herbicide application shall be treated with a second application of the Roundup Custom or equal herbicide mixture resulting in a complete kill of all existing vegetation. Broadcast or “Boom” spraying of herbicide is acceptable under these conditions; precautions shall be taken to eliminate damage to non-target areas from overspray.

Prior to seeding, remove dead biomass within planting areas using a landscape rake or other method approved by the Engineer. Where possible, planting areas designated to receive Supplemental Wetland Seed Mix for Wet Soils shall be tilled 2 to 4 inches deep in order to break up the existing salt layer.

Once dead biomass is removed from the planting areas, spread soil amendments products within all planting areas, see special provision for SOIL AMENDMENTS.
