3.2.1 Suitable Materials

Excavated materials which are suitable for incorporation in the berm embankment, shall be stockpiled and subsequently used in the berm embankment as specified is Section 31 24 00.00 09 EMBANKMENT, paragraph "Uncompacted Embankment."

3.2.2 Unsuitable Materials

Materials from excavation which, as defined in Section 31 24 00.00 09 EMBANKMENT, paragraph "Unsuitable Materials", are unsuitable for berm embankment, or other fill material will be ordered wasted and shall be disposed of in abandoned portions of borrow areas. This unsuitable material shall be shaped so that its surface is free from abrupt changes in grade and shall be sloped to drain. Where possible, unsuitable materials in borrow areas shall not be removed.

3.2.3 Temporary Stockpiles

No material shall be stockpiled on the existing levee. Temporary stockpile areas shall be approved by the Contracting Officer before being used.

3.3 BORROW AREA EXCAVATION

Borrow areas shall conform to requirements prescribed herein and as shown on the drawings. The material necessary for the construction of the embankments shall be procured from borrow areas and required excavations by haulage or otherwise. The required excavation line and the permissible excavation depths in the borrow areas are indicated on the drawings, but the right is reserved, in accordance with the Contract Clause CHANGES, to modify the permissible depths in accordance with subsurface conditions determined as the work proceeds. Excavation to the required excavation line and the permissible depths may require excavation below the ground water table. The bottom of the borrow areas excavated under this contract shall be dressed to the extent necessary to provide a reasonably smooth surface that can readily be traversed by a 50 to 60-horsepower farm tractor pulling a rotary-type pasture mower and sloped to provide surface drainage to the low side of the borrow area as soon as all usable materials have been removed or the Contractor has completed the use of the borrow area.

SECTION 31 23 00.00 09 Page 2

Abrupt changes in grade shall be avoided. Unsuitable material wasted in the borrow areas shall be sloped to drain. Any excavation below the depths and slopes specified herein or shown on the drawings shall be backfilled by the Contractor, at no cost to the Government, to the specified permissible excavation line, with suitable material placed and compacted in accordance with Section 31 24 00.00 09 EMBANKMENT, paragraph SEMICOMPACTED EMBANKMENT.

The borrow areas excavated under this contract and inundated from high river stages shall be drained and allowed to dry to a workable condition as quickly as practicable after the high river stage has passed. No additional payment will be made for keeping the borrow areas drained and free of water during excavation. The Contractor shall not use rights-of-way for drainage of the borrow area other than those rights-of-way furnished by the Government. Except as required by variable right-of-way widths, abrupt changes in borrow area alignment shall be avoided. Excavation shall begin at the upstream end of the borrow area. To make optimum use of available borrow, the excavation of the borrow areas shall be made continuous throughout the width of the borrow area to the depths shown on the drawings, and at the length necessary to provide the required quantity of suitable material, and in such manner that all suitable available material within the required length between the leveeward limits of the borrow areas and the back of the borrow areas will be utilized. The Contractor shall submit an excavation plan for approval by the Contracting Officer and shall not begin excavation until the Contracting Officer's approval has been received. The plan shall contain, as a minimum, the following:

a. The Contractor's proposals for implementing Section 01 57 20.00 09 ENVIRONMENTAL PROTECTION insofar as that section applies to borrow areas.

b. The Contractor's proposed methods for draining and keeping the borrow areas free of water during excavation under this contract.

c. The Contractor's proposed methods for draining borrow areas excavated under this contract which may be inundated by high river stages.

d. The Contractor's proposals for making optimum use of available borrow, including the Contractor's proposed methods for smoothing the bottom of the borrow areas after having completed use of the borrow areas.

SECTION 31 23 00.00 09 Page 4

3.1 HAUL ROADS

Haul roads between borrow area and fill areas shall meet the minimum requirements specified herein. At no additional cost to the Government, the Contractor shall increase the minimum specified requirements as necessary, due to job site conditions, to assure safe operations. Whenever practical, one-way haul roads shall be used. Haul roads used for this work shall comply with the following:

(a) One-way haul roads for off-the-road haulage equipment; (e.g., belly dumps, scrapers, and off-the-road trucks) shall have a minimum usable width of 25 feet. One-way haul roads for over-the-road haulage equipment (e.g., dump trucks, etc.) shall have a minimum usable width of 15 feet.

When it is impractical to obtain the specified minimum widths for one-way haul roads, a usable width of not less than 10 feet may be approved, provided a positive means of traffic control is implemented.

Such positive means shall include signs, signals, or signalmen and an effective means of speed control.

(b) Two-way haul roads for off-the-road haulage equipment shall have a minimum usable width of 60 feet. Two-way haul roads for over-the-road haulage equipment shall have a minimum usable width of 30 feet.

(c) Haul roads shall be maintained to keep the surface free from potholes, ruts and similar conditions that could result in unsafe conditions. Haul roads shall be maintained free of all construction related debris, including loose riprap.

(d) Curves and changes in grade shall allow a minimum sight distance of 200 feet for one-way haul roads and 300 feet for two-way haul roads. Sight distance is defined as the centerline distance an equipment operator (4.5 feet above the road surface) can see an object

4.5 feet above the road surface. When conditions make it impractical to obtain the required minimum sight distances (e.g., ramps over levees), a positive means of traffic control shall be implemented.

(e) Dust abatement shall permit observation of objects on the roadway at a minimum distance of 300 feet.

(f) Haul roads shall have the edges of the usable portion marked with posts at intervals not greater than 50 feet on curves and not greater than 200 feet elsewhere. Such markers shall extend 6 feet above the road surface, and for nighttime haulage shall be provided with reflectors in both directions.

(g) Haul roads shall not block or impede drainage in or through the right-of-way. The Contractor is responsible for any damages resulting from haul roads blocking or impeding drainage. (See the Contract Clause PERMITS AND RESPONSIBILITIES.)

3.2 EXCAVATION IN BORROW AREAS

3.2.1 General

The rights-of-way and earth materials for constructing the work will be furnished without cost to the Contractor, at locations specified herein and shown on the drawings. Notwithstanding any other provision of this

SECTION 31 23 00.00 09 Page 5 contract, the Contractor is required to obtain all borrow material from the Government furnished borrow areas, ditches and other required excavations.

Contractor furnished borrow areas will not be permitted.

3.2.1.1 Equipment

The Contractor shall provide the types of equipment as necessary to perform the required excavation according to the in situ conditions of the borrow areas.

3.2.2 Borrow Areas

3.2.2.1 Requirements

Borrow areas shall conform to requirements prescribed herein and as shown on the drawings. The material necessary for the construction of the embankments shall be procured from borrow areas and required excavations by haulage or otherwise. The permissible excavation depths in the borrow areas are indicated on the drawings, but the right is reserved, in accordance with the Contract Clause CHANGES, to modify the permissible depths in accordance with subsurface conditions determined as the work proceeds. Excavation to the permissible depths may require excavation below the ground water table. The bottom of the borrow areas excavated under this contract shall be dressed to the extent necessary to provide a reasonably smooth surface that can readily be traversed by a 50 to 60-horsepower farm tractor pulling a rotary-type pasture mower and sloped to provide surface drainage to the low side of the borrow area as soon as all usable materials have been removed or the Contractor has completed the use of the borrow area. Abrupt changes in grade shall be avoided.

Unsuitable material wasted in the borrow areas shall be sloped to drain.

Any excavation below the depths and slopes specified herein or shown on the drawings shall be backfilled by the Contractor, at no cost to the Government, to the specified permissible excavation line, with suitable material. The borrow areas excavated under this contract shall be drained of water regardless of its source, including subsurface water, and kept free of water during excavation, as excavation will not be permitted in water nor shall excavated material be scraped, dragged or otherwise moved through water. Drainage of borrow areas shall be accomplished by ditching, sump pumping or other approved methods. The borrow areas excavated under this contract and inundated from high river stages shall be drained and allowed to dry to a workable condition as quickly as practicable after the high river stage has passed. No additional payment will be made for keeping the borrow areas drained and free of water during excavation. The Contractor, at his option, may use rights-of-way for drainage other than those furnished by the Government provided that no additional clearing is required and their location and dimensions are approved by the Contracting Officer, and provided that the Contractor has obtained the rights-of-way in accordance with Section 01 00 00.00 09 GENERAL CONTRACT REQUIREMENTS, paragraph RIGHTS-OF-WAY. Except as required by variable right-of-way widths, abrupt changes in borrow area alignment shall be avoided. To conserve arable land and make optimum use of available borrow, the excavation of the borrow areas, shall be made continuous throughout the width of the borrow areas to the permissible borrow depths, and at the length necessary to provide the required quantity of suitable material, and in such manner that all suitable available material within the required length between the leveeward limits of the borrow areas and the back of the borrow areas will be utilized. The Contractor shall submit an excavation plan for approval by the Contracting Officer and shall not begin excavation until the Contracting Officer's approval has been received. The plan shall

SECTION 31 23 00.00 09 Page 6 contain, as a minimum, the following:

a. The Contractor's proposals for implementing Section 01 57 20.00 09 ENVIRONMENTAL PROTECTION insofar as that section applies to borrow areas.

b. The Contractor's proposed methods for draining and keeping the borrow areas free of water during excavation under this contract.

c. The Contractor's proposed methods for draining borrow areas excavated under this contract which may be inundated by high river stages.

d. A statement indicating whether the Contractor proposes to use:

(1) Government-furnished rights-of-way for drainage;

(2) Contractor-furnished rights-of-way for drainage; or

(3) A combination of Government-furnished and Contractor-furnished rights-of-way for drainage.

e. For Contractor-furnished rights-of-way for drainage, the plan shall contain all of the information required by paragraph REQUIREMENTS and the Contractor's proposals for implementing Section 01 57 20.00 09 ENVIRONMENTAL PROTECTION, insofar as that section applies to rights-of-way for drainage.

f. The Contractor's proposals for conserving arable land and for making optimum use of available borrow, including the Contractor's proposed methods for smoothing the bottom of the borrow areas after having completed use of the borrow areas.

3.2.2.2 Borrow Area Locations

Borrow areas shall be located as shown on the drawings.

3.3 DISPOSITION OF MATERIALS

3.3.1 Suitable Materials

Excavated materials which are suitable for incorporation in the berm embankment or other required fill or backfill, shall either be placed directly therein, or stockpiled and subsequently used in the berm embankment or other required fill or backfill.

3.3.2 Unsuitable Materials

Materials from required excavation which, as defined in Section 31 24 00.00 09 EMBANKMENT, paragraph UNSUITABLE MATERIALS, are unsuitable for berm embankment, or other fill material will be ordered wasted and shall be disposed of in abandoned portions of the construction borrow area. This unsuitable material shall be shaped so that its surface is free from abrupt changes in grade and shall be sloped to drain. Where possible, unsuitable materials in borrow areas shall not be removed.

3.3.3 Temporary Stockpiles

No material shall be stockpiled on the existing levee. Temporary stockpile

SECTION 31 23 00.00 09 Page 7 areas shall be approved by the Contracting Officer before being used.

3.4 EXCAVATION IN OTHER AREAS

3.4.1 General

Excavation from other areas shall consist of removal of material in preparing the berm embankment foundations to the lines and grades shown on the drawings, removal of materials from ditches, and removal of unsuitable materials as defined in Section 31 24 00.00 09 EMBANKMENT, paragraph UNSUITABLE MATERIALS. Whenever unsuitable foundation material is encountered, the unsuitable material shall be removed to the depth directed by the Contracting Officer. Care shall be exercised by the Contractor in excavating to the lines and grades shown and in removing unsuitable materials so as not to excavate below the grades specified or depth directed. Excavation below the lines and grades specified or the depth directed shall be backfilled by the Contractor at no cost to the Government. Such backfill shall be brought to grade with suitable material. Excavated materials shall be disposed of as specified in paragraph DISPOSITION OF MATERIALS.

3.4.2 Drainage Ditches

3.4.2.1 Excavation

Drainage ditches shall be excavated to the cross sections, lines, and grades shown on the drawings. All suitable material excavated from the ditches shall be used in the berm embankment. Material unsuitable for use in the berm embankments shall be wasted in the borrow area. The right is reserved to require such other ditching as is deemed desirable and which can be performed without unreasonable difficulty by the equipment on the job. Suitable material excavated from such ditching may, at the option of the Contractor, be used in the embankment. Material not so used shall be wasted in the borrow area.

3.4.2.2 Grade Tolerances

For ditch excavation, at all points a tolerance of 5/10 of 1 foot below the grades and cross section shown on the drawing will be permitted.

3.4.2.3 Acceptance

Prior to the acceptance of the work, the Contractor shall excavate sediments from ditches as necessary to restore them to grade and section.

Disposal of such material shall be as directed by the Contracting Officer.

No separate payment will be made for this work.

3.5 DEGRADING EXISTING EMBANKMENTS

3.5.1 Embankments to be Degraded

No embankment areas are to be degraded.

3.5.2 Embankments Not to be Disturbed

Existing levees, parts of levees, sublevees, spurs, or other embankments shall not be disturbed unless it is specifically stated in paragraph EMBANKMENTS TO BE DEGRADED or shown on the drawings that they may be degraded.

SECTION 31 23 00.00 09 Page 8

3.5.3 Unauthorized Excavation of Existing Levee or Berm

Excavation of any portion of the existing levee or berm without written authorization by the Contracting Officer is expressly prohibited. Should such unauthorized excavation occur, the Contractor will be required to cease construction operations and to restore the levee or berm to its original grade and section before further construction operations will be permitted. The restoration shall be made with suitable levee embankment material, placed and compacted as provided in Section 31 24 00.00 09 EMBANKMENT, paragraph SEMICOMPACTED EMBANKMENT, and by and at the expense of the Contractor.

3.6 TRAVERSES

The Contractor shall construct traverses as necessary for his operation.

The Contractor shall remove all traverses and haul roads after completing his use of the borrow area. No separate payment will be made for this work and all costs therefore shall be included in the contract unit prices for "Berm Embankment, Uncompacted", as applicable.

PART 2 PRODUCTS

2.1 EMBANKMENT MATERIALS

2.1.1 General

The berm embankment shall be constructed of earth obtained from the borrow area and ditch excavation as prescribed in Section 31 23 00.00 09 EXCAVATION and to the extent shown on the drawings. Contractor furnished borrow areas will not be permitted. The berm embankment shall be constructed of earth that is free from unsuitable and frozen materials as defined in paragraphs UNSUITABLE MATERIALS and FROZEN MATERIALS. Material classified in accordance with ASTM D2487 as gravels (GW, GP, GM) and sands (SW, SP, SM) shall not be used for any required embankment construction unless suitably blended with less pervious material to the extent that it no longer classifies as these materials. Uncompacted berms may be constructed of material that classifies as sands (SW, SP, SM), clays (CH, CL) or silts (ML), except that the top 1 foot of the uncompacted berms shall be constructed of material that classifies as clays (CH, CL) or silt

(ML).

2.1.2 Unsuitable Materials

Materials which are classified as unsuitable for berm embankment are defined as masses of organic matter, sticks, branches, roots, and other debris. As earth from the designated borrow area may contain excessive amounts of wood, isolated pieces of wood will not be considered objectionable in the embankment provided their length does not exceed 1 foot, their cross-sectional area is less than 4 square inches, and they are distributed throughout the fill. Not more than 1 percent (by volume) of objectionable material shall be contained in the earth material placed in each cubic yard of the berm section. Pockets and/or zones of wood shall not be placed in the embankment.

2.1.3 Frozen Materials

Under no circumstances shall frozen earth, snow, or ice be placed in any required embankment.

PART 3 EXECUTION

3.1 EMBANKMENT FOUNDATION PREPARATION

3.1.1 General

After clearing and grubbing and any required excavation of the berm embankment, test areas and other similar cavities and depressions shall be broken down to flatten out the slopes. The entire earth surface on or against which semicompacted fill is to be placed shall be thoroughly broken to a depth of 6 inches. If for any cause, this broken surface becomes compacted in such a manner that, in the opinion of the Contracting Officer, a plane of seepage or weakness might be induced, it shall again be adequately scarified before depositing material thereon. All of the foregoing work shall be completed at least 200 feet in advance of the berm embankment construction.

3.1.1 Drainage

The foundation receiving fill, and all partially completed fill shall be kept thoroughly drained. Drainage to areas outside the right-of-way limits will be allowed only after the Contractor has obtained rights-of-way for such drainage in accordance with Section 01 00 00.00 09 GENERAL CONTRACT REQUIREMENTS, paragraph RIGHTS-OF-WAY. Drainage of foundation areas for uncompacted berm will not be required. However, the Contractor may, at his option and expense, drain such foundation areas.

3.1.2 Frozen Ground

No fill shall be placed upon frozen ground.

3.2 EMBANKMENT CONSTRUCTION

3.2.1 Uncompacted Embankment

The location and extent of the uncompacted embankment shall be as shown on the drawings. It is intended that material for uncompacted embankment be placed at its natural moisture content. Uncompacted embankment shall be placed in horizontal layers not exceeding 3 feet in thickness. The layers shall be uniformly spread, distributed, and otherwise manipulated during placement to such an extent that individual loads of material deposited on the fill will not remain intact, and large, open voids in the fill will be eliminated. Layers shall be started full out to the slope stakes, and shall be carried in lifts horizontal and parallel to the centerline with sufficient crown or slope to provide satisfactory drainage during construction.
