CONSTRUCTION SPECIFICATION

400. STREAM DEBRIS REMOVAL

1. SCOPE

The work will consist of the cleanup of storm debris in the designated streams (channel, canal, waterway, etc.) areas by the removal and disposal of trees, logs, stumps, brush, tops, blockages, rubbish, and debris deposited in and adjacent to the channel and other items as specified in Section 10. The designated sites are as shown on the drawings.

2. ACCESS

Access shall be as designated by the Engineer unless alternate routes are obtained by the Contractor and approved by the Engineer.

3. LIMITS OF WORK

The limits of the work area shall not exceed those shown on the drawings. The limits of the designated stream debris removal area are referenced in section 10 of this specification and as shown on the drawings.

4. DEBRIS REMOVAL

Flow obstructions shall be removed by methods including, but not limited to, sawing, cabling, winching, lifting, or dragging or as specified in Section 10. Excavation shall be limited to that necessary for sediment and stump removal.

The following guidelines will be used to determine which trees, stumps, and brush to remove.

The ENGINEER will make the final determination on questionable items.

a. All downed trees, brush, limbs, root mass, tops, vines, and other washed-in woody vegetative materials lying completely or partially within the stream banks shall be removed.

b. Undermined or storm damaged trees within or outside the banks which are still standing but likely to fall into the stream shall be removed.

c. Stumps of downed or undermined trees within the channel bank or bottoms shall be removed.

d. Any root mass located on the channel bank that has become unstable or that obstructs flow in the channel shall be removed.

Trees designated for removal shall be cut off as near to the ground surface as conventional cutting tools or field conditions will permit.

All building materials, manufactured items, and other loose foreign debris lying completely or partially within the limits of designated areas shall be removed.

Water level in the channel will fluctuate up and down due to rainfall events. The extent of debris removal in the channel cross section is not changed by the fluctuation in the water level. Excavation of soil/sediment shall not be performed, unless otherwise stated in Section 10.

Florida - EWP 400-2 November 2004

Trees that have been "snapped", are not leaning, have a strong root structure, and pose no threat to the channel will be left as they are, provided the contractor does not need to remove the tree for access purposes. Naturally leaning trees with apparently undamaged root systems and other natural, undamaged vegetation shall remain in its natural condition and not be removed.

Trees shall be felled in such a manner as to avoid damage to trees left standing or existing structures and with due regard for the safety of persons and property.

Removal of standing trees outside of stream banks is limited to the cutting of severely damaged trees leaning across the channel and other trees as needed to gain access for equipment to points of channel blockage.

The approval of the Engineer or Construction Inspector shall be obtained prior to cutting any "healthy" tree for equipment access.

Unless otherwise approved, access for mechanized equipment shall be limited to one side of the channel. Access to the channel shall generally be perpendicular to the channel with precautions taken to protect mast producing and stream canopy trees.

Dead trees that provide den habitat and are determined to pose no hazard to the channel shall be protected. Disturbance of the channel bottom and banks, and equipment access areas shall be held to the minimum necessary to allow the construction equipment to remove the debris.

Heavy equipment working on wet soil conditions must operate from mats or use other measures as approved by the Engineer to minimize rutting or soil disturbance.

5. DISPOSAL

All foreign debris such as building materials and manufactured items (stoves, refrigerators, washing machines, other household goods, cars, tin, building material, etc.) found within the limits of the debris cleanup area shall be hauled to the off-site disposal area(s) designated as specified in Section 10 or alternative sites that are obtained by the Contractor and approved by the Engineer. Unless other wise specifically approved by the receiving landfill, all debris will have to be separated by woody, construction and demolition, "white goods", and tires prior to placement in the landfill.

Natural woody and other vegetative debris shall be hauled to designated disposal areas and burned or disposed of as specified in Section 10. Alternate methods of disposal proposed by the Contractor must be approved by the Engineer.

Sediment removed from the watercourses shall be placed and spread as specified in Section

10. No sediment shall be placed on improved property except where directed or allowed by the Engineer to fill stump holes, ruts, and other local depressions. Alternate methods of disposal proposed by the Contractor must be approved by the Engineer.

Debris shall not be placed in tributaries, side ditches, floodplains nor other defined water entrances to the watercourse being cleaned.

Also, when one side of the channel is through improved areas and the other side is woods, it is not permissible to dispose of the stream debris from the improved side on the side that is in woods (to avoid haul-off) unless prior approval is granted from the Engineer. Nor is it permissible to place debris on the property of others, to "pile up" debris, or to move debris upstream or downstream in improved areas to dispose of debris in wooded areas to avoid hauling off-site unless otherwise approved by the Engineer.

Florida - EWP 400-3 November 2004

Debris shall not be placed on nature or hiking trails, sewer line, highway, or railroad rights-of-way, or any other improved area. Debris shall not be placed in tributaries or side ditches.

The debris shall be placed in such a manner to prevent potential movement of the materials back into the floodway by subsequent high water flows. The Contractor shall leave openings in debris piles to allow lateral flow to the stream.

Where petroleum or gas tanks, pesticide containers or other hazardous materials are found within the limits of debris cleanup, the contractor shall note the location of the tank, container, or material and notify the Construction Inspector. The contractor shall avoid disturbance or damage to the tank, container, or materials.

6. ENVIRONMENTAL REQUIREMENTS

Where the use of heavy equipment is allowed, equipment shall operate adjacent to the stream and not within the stream unless prior approval is granted by the Engineer. Crossing a stream with equipment to gain access to the opposite bank is only allowed with the specific approval of the Engineer or Construction Inspector.

Unless otherwise directed, established beaver dams shall be "notched" from the top of the beaver dam to the channel bottom to lower the water level to facilitate the removal of debris.

Established dams are generally those that have been in place long enough to have affected the native vegetation in the ponded area (i.e. non-wetland trees have died and may be identified by falling limbs, falling bark, woodpecker holes, etc. Established dams generally have been in place two or more growing seasons. New dams (those that have been in place less than two growing seasons and where trees in the ponded areas are not dead or there is not evidence as described for established dams) shall be completely removed. Should an area of the channel be encountered which is affected by beavers and it is unclear to the contractor whether the dam should be notched or removed; the Engineer or Construction Inspector shall be notified prior to any construction work in the impacted area. The Engineer or the Construction Inspector will make the determination. The debris removal limits, within the impacted area, shall be the same as other areas if the channel is well defined. In the areas where the width of the channel has been significantly altered by the effects of the beaver dam, the channel width is determined by the greater of the channel width immediately upstream or downstream of the impacted area.

Equipment shall be maintained to prevent fuel, oil, and lubricant spills. Refueling, repairs, and lubrication will be performed at safe distances from the stream. Should fuel leaks, oil leaks or hydraulic pipe rupture occur during construction, the Contractor's operators shall immediately remove the equipment to a safe area and take prompt action to minimize damage and safeguard the site. The contractor or his Superintendent shall immediately report the spill or discharge in accordance with the Special Provisions of this Contract; and the requirements of the Florida Statute Chapter 376 Pollution Discharge Prevention and Removal will be followed.

The Contractor shall provide tanks or barrels to be used for off-site disposal of chemical pollutants such as drained lubricating or transmission oils, greases, etc. produced as a by-product of this work. Washing, fueling or servicing of equipment shall be avoided where spillage or wash water can enter the watercourse.

Florida - EWP 400-4 November 2004

7. SPECIAL REQUIREMENTS

The Contractor shall submit to the Engineer for review and approval prior to construction, a construction schedule showing the sequence of all work by reaches to be performed.

The Contractor shall exercise care while working in the areas of existing lawns, roads, structures, utilities, railroads, other improvements and cropland. The Contractor shall be responsible for the prompt repair or replacement of any such improvements damaged by his/her operations.

Fences which must be removed for access shall be removed with the minimum damage practical and reinstalled as near to the original condition as possible immediately after construction access is no longer needed at the site.

In areas identified in Section 10 of this specification, or on the drawings, as "Hand Work";

portable winches, chainsaws, hand held tools, block and tackle, cables, log chains, etc., and manual labor will be allowed, unless the Contractor requests, in writing, approval for the use of heavy equipment at specific locations and the request is approved by the Engineer. Boats and barges with equipment working from the deck of the barge may be used in “Hand Work” areas when the Contractor makes a written request and permission is given by the Engineer or the Construction Inspector.

Disturbance of the stream banks and the stream bottom will be held to the minimum necessary to remove the debris.

Where the haul off of debris is required in improved areas at "Hand Work" sites, wheeled and/or tracked vehicles for removing, loading and hauling the debris off-site will be allowed at specified selected locations as designated by the Engineer or Construction Inspector.

The Contractor shall be responsible for complying with all applicable requirements of the Florida Department of Transportation's Manual on Uniform Traffic Control Devices as adopted by the Department of Transportation pursuant to Chapter 316 Florida Statute when work is performed on public right-of-ways. When equipment or personnel are operating on public right-of-way, flagmen shall be stationed to warn oncoming traffic of congestion.

Proper construction road signs shall be in place. A means of removing sediment and/or debris from roadways shall be established. Sweep machines may remove residue deposited on roadways, manual sweeping methods or pressurized water. The Contractor shall be responsible for implementation of these measures.

8. EQUIPMENT

Hydraulic excavators, if used, shall be low ground pressure (LGP) machines and be equipped with a stationary or mechanical thumb attachment or have a grapple. The use of rubber tired skidders will not be allowed without prior written approval of the Engineer. When the use of skidders is allowed, they shall be equipped with low ground pressure, high flotation tires.

Each work site shall have two-way communication capabilities. This requirement shall be met with cellular phones or two-way battery operated radios. Radios shall have a broadcast capability of a minimum of 5 watts.
