CLEARING AND GRUBBING

Clearing and grubbing shall consist of removing all objectionable material, and material as

designated in these Specifications, from within the work site, or other areas as shown on the

Plans or specified in the Special Provisions.

The methods of removing existing facilities shall conform to Section 13, “Existing Facilities”,

of these Specifications.

Attention is directed to Section 10, “Environmental Controls at Work Site”, of these

Specifications for additional requirements.

Clearing and grubbing operations must not cause more than minimal damage to public and

private property, and improvements, including existing trees, shrubbery and lawns, outside of

the work site, or other areas as shown or specified in the Contract.

15-1.01 Vegetation and Debris

Vegetation designated for removal, such as weeds, grass, shrubbery, roots, and stumps,

and debris, such as broken concrete and trash, shall be removed from the right-of-way or

construction areas and disposed of by the Contractor. Vegetation to remain shall be protected

15-1.02 Trees, Shrubs, Ground Cover, and Lawns

For the purpose of these Specifications, trees shall be defined as having a trunk diameter

(DBH = diameter at breast height) of three inches (3”) and greater measured at a height of four

and one-half feet (4-1/2’) above the ground. Shrubs shall be defined as single or multi-stem

individual plants, not of tree size. Ground cover shall be defined as multiple spreading and

matting plant material of a density to cover bare ground, including turf lawn.

Only plant material shown on the Plans to be removed and disposed of shall be removed

and disposed of. Prior to the clearing and grubbing operations on a particular property or

portion of the work site, the Agency will mark and designate the trees, shrubs, and ground cover

areas to be removed and disposed of.

Trees, shrubs and ground cover that are not to be removed shall be protected from injury or

damage. Attention is directed to Section 10-13, “Protection of Existing Trees”, of these

Specifications for protection of certain existing trees within the County of Sacramento.

Trees, shrubs and ground cover designated to be relocated, and not specifically designated

for disposal, shall be preserved by removing an adequate and substantial root mass of native

soil and roots with the rootball wrapped in burlap and kept moist until the Work has progressed

to permit the replanting. The removal and replanting shall be performed in a careful and

professional manner at the direction of an Arborist certified by the International Society of

Arborists, hereinafter designated as a “Certified Arborist”. The tree trimming shall be limited to

tree limbs required to be removed to allow for minimum required vehicular clearance. Tree root

cutting shall be limited to that which is required for earthwork operations, so as to minimize

impact on existing trees. All roots one-half inch (1/2”) in diameter or greater shall be cut cleanly

and sealed as directed by the Certified Arborist or by the Certified Arborist's staff. Any root

cutting on trees to remain which, in the opinion of the Certified Arborist, will jeopardize the

health or stability of the tree shall be brought to the attention of the Agency for specific

instructions prior to the cutting of the roots.

The Contractor shall submit the name of the Certified Arborist to the Agency, in writing, a

minimum of four (4) Working Days prior to the start of clearing and grubbing operations.

Tree branches or portions of shrubs which extend over a roadway shall be trimmed to

provide a minimum clearance of fourteen feet (14’) above the shoulder point of the roadbed,
