Certification

The CONTRACTOR shall provide the Engineer a certified test report from the manufacturer of the commercial fertilizer confirming that the requirements of this Section are met. The certified test report shall include test results for total nitrogen, available phosphoric acid, water-soluble potash, and sulfur. Each certification shall cover one batch per type for dry type fertilizer.

H-12

Fertilizer Rates

Soil laboratory fertilization recommendations are based on the amount (lbs) of nutrients (N, P2O5, K2O) to apply per given area (usually 1,000 square feet.). From this recommendation it is necessary to select an appropriate fertilizer grade and then determine how much of this fertilizer to apply to the area.

If a complete fertilizer (containing all three primary nutrients) is not available in the ratio of N-P-

K necessary to match the ratio required in the fertilizer recommendation, mixed-grade or single-nutrient fertilizers should be used to satisfy each nutrient requirement.

To calculate fertilizer rates:

• Measure the area to be fertilized in square feet.

• Select fertilizers, to be used based on the soil testing laboratory recommendations by matching the ratio of nutrients recommended to the fertilizer grades available.

• Determine the amount of fertilizer to apply to a given area (1,000 square feet.) by dividing the recommended amount of nutrient by the percentage of the nutrient (on a decimal basis) in the fertilizer. Apply no more than 0.25 lbs P2O5/1000 square feet per application prior to planting.

• Adjust the amount of fertilizer to the project area.

Insecticides and Herbicides

Use products found on the following website, http://ceris.purdue.edu/, approved by the

Florida Department of Agriculture for the State of Florida. The use of restricted products is prohibited. Do not use any products in the sulfonylurea family of chemicals. Herbicide application by broadcast spraying is not allowed.

Chapter 62C-20, Florida Administrative Code, Rules of the Florida Department of

Environmental Protection. Contact the Regional Field Office of Bureau of Invasive Plant

Management of the Florida Department of Environmental Protection for proper permits and subsequent approval. If application of synthetic organo-auxin herbicides is necessary, meet the requirements of Chapter 5E-2, Florida Administrative Code.

Water

The water used in the grassing operations may be obtained from any approved source.

The water shall be free of any substance, which might be harmful to plant growth. Effluent water shall meet all Federal, State and local requirements.

Construction Methods

Incorporate turf installation into the project at the earliest practical time.

Use the methods and materials necessary to establish and maintain the initial grassing until final acceptance.

Sod: Place the sod on the prepared surface, with edges in close contact. Do not use sod which has been cut for more than 48 hours.

Place the sod to the edge of all landscape areas as shown in the Plans and as shown in the Design

Standards.

Place rolled sod parallel with the roadway and cut any exposed netting even with the sod edge.

Monitor placed sod for growth of pest plants and noxious weeds. If pest plants and/or noxious weeds manifest themselves within 30 days of placement of the sod during the months April through October, within 60 days of placement of the sod during the months of November

H-14 through March treat affected areas by means acceptable to the COUNTY at no expense to the

COUNTY. If pest plants and/or noxious weeds manifest themselves after the timeframes described above from date of placement of sod, the Engineer, at his sole option, will determine if treatment is required and whether or not the CONTRACTOR will be compensated for such treatment.

Remove and replace any sod as directed by the Engineer.

Turf Establishment

Perform all work necessary, including watering and fertilizing, to sustain an established turf until final acceptance, at no additional expense to the COUNTY. Provide the filling, leveling, and repairing of any washed or eroded areas, as may be necessary.

Established turf is defined as follows:

1. An established root system (leaf blades break before seedlings or sod can be pulled from the soil by hand).

2. No bare spots larger than one square foot.

3. No continuous streaks running perpendicular to the face of the slope.

4. No deformation of the turf areas caused by mowing or other CONTRACTOR equipment.

5. No exposed sod netting.

6. No pests or noxious weeds.

Edition, http://www.fleppc.org). Remove such vegetation regularly by manual, mechanical, or chemical control means, as necessary. When selecting herbicides, pay particular attention to ensure use of chemicals that will not harm desired turf. Use herbicides in accordance with provision

During the entire establishment period and until turf is established in accordance with this specification, continue inspection and maintenance of erosion and sedimentation control. Take responsibility for the proper removal and disposal of all erosion and sedimentation control items after turf has been established.

H-15

Notify the Engineer, with a minimum of seven calendar days advance notice, to conduct inspections of the turf at approximate 90-day intervals during the establishment period to determine establishment. Results of such inspections will be made available to the

CONTRACTOR within seven calendar days of the date of inspection. Determination of an established turf will be based on the entire project and not in sections.

The CONTRACTOR’S establishment obligations of this specification will not apply to deficiencies due to the following factors, if found by the Engineer to be beyond the control of the

CONTRACTOR, his subcontractors, vendors or suppliers:

• Determination that the deficiency was due to the failure of other features of the Contract.

• Determination that the deficiency was the responsibility of a third party performing work not included in the Contract or its actions.

The COUNTY will only pay for replanting as necessary due to factors determined by the

COUNTY to be beyond the control of the CONTRACTOR.

Litter Removal

During each cycle all litter and debris are to be removed prior to and upon completion of a mowing cycle. Litter and debris removal includes the pickup removal, and disposal from the right-of-way and COUNTY property of any obstacle such as wood, signs, tires, cans, etc., which cannot be traversed by the mowing equipment. It will also be the CONTRACTOR’S responsibility to remove any items such as bags of trash, newspapers, magazines, food containers, boxes, sheets of paper, etc., which will be torn, ripped, scattered or further subdivided by the mowers, which will result in an objectionable appearance.

Clipping Removal

During each cycle all grass clippings that are not uniformly distributed and detract from the appearance of the mowing operation will be removed from the site by the CONTRACTOR, upon completion of the mowing operation to allow for a neat and clean appearance after completion.

The CONTRACTOR will remove and dispose of all grass clippings from the pavement, curbs and curb inlets located within the limits of the project.

The grass clipping removal will be performed in conjunction with the mowing cycle. It is the responsibility of the CONTRACTOR to maintain the inlet openings free from the debris generated during their right-of-way mowing operation. Grass clippings will not be blown into

H-16 drains or storm drain inlets. Failure to adhere to this will result in the CONTRACTOR, at his/her own expense within two (2) working days, jetting out these pipes and drains or reimbursing the

COUNTY for the clean-up effort carried out by COUNTY personnel.

Edging

Edging is the removal of all weeds, sand, vegetation, debris and plant material by the

CONTRACTOR from all edges of curbs, to maintain these areas in an attractive and manicured condition. Edging includes the removal of growth mechanically and manually and shall be performed in conjunction with the mowing cycle. The edging of curbs will create a distinct void;

approximately one-half (1/2) inch horizontally between the structure and the turf. String trimmers will not be used in edging. Edging also includes the removal of all sand and debris from the areas designated to be edged. Upon completion of edging by the CONTRACTOR, no growth, sand or debris will touch any of the structures designated to be edged. The

CONTRACTOR from the areas designated for edging will remove all sand and debris.

NOTE: Areas specified for edging will not be treated with herbicide.
