The Contractor shall maintain the replacement ornamental landscaping for a period of 8 weeks, and replacement trees for a period of one year, to assure a satisfactory replacement. Replacement ornamental plantings or trees that are dead or dying, as determined by the Project Manager, at the end

Section 01560 - 22 of the 8 week or one year establishment period shall be replaced by the Contractor to the satisfaction of the Project Manager and at no cost to the Owner. Should it not be practical to replace the ornamental landscaping or tree, the Contractor shall pay damages in accordance with requirements of the Project Manager. In the event the Contractor does not perform this replacement Work in a timely manner as determined by the Project

Manager, the Project Manager reserves the right to have the Work performed by others.

The expense of replacing ornamental landscaping or trees will be charged against the

Contractor and the cost withheld from Contractor’s payments.

E. A Critical Root Zone (CRZ) shall be established for all trees on-site that need protection.

The CRZ shall be the area between the tree trunk and a surrounding protective barrier fence. The protective barrier fence shall be placed at a minimum distance of the dripline for broad-crowned trees (usually deciduous) and 1.5 times the dripline for narrow-crowned trees (usually conifers). For asymmetrical crowns, the dripline shall be determined at the crown’s widest point. The Project Manager shall have the discretion to require fencing to be placed at a distance of a 1-1.5’ radius for each inch of tree diameter at 4.5’ (diameter breast height) if he/she feels that the dripline does not provide adequate protection. Regardless of diameter, fencing shall be placed at a minimum of 6’ from the trunk of a tree. No disturbance of any kind shall take place within the fenced area (CRZ).

Fencing shall not be removed or relocated without approval from Project Manager.

F. When roots greater than 1” diameter are exposed, root pruning with a saw shall take place under the supervision of the Project Manager.

Roots that must be cut shall be treated as follows:

a. All jagged ends of roots caused by excavation shall be pruned cleanly back to a solid root structure with no splits or tears evident. The final cut at the edge of the trench shall be done with a 10 to 14 point hand saw.

b. Roots shall be kept moist until the area is backfilled. Spot placement of backfill to provide support shall be permitted with Project Managers approval.

G. When tree removals are required, stumps shall be ground rather than pulled when roots are intertwined with the root systems of adjacent trees. Stumps may be pulled when there is no danger of interfering with the roots of adjacent trees.

H. The Project Manager may request that a 6-10” layer of mulch be applied over the CRZ of trees on site before any construction activity begins to help reduce soil compaction.

Following construction, the mulch shall be reduced to a depth of 4”. The Project

Manager may also request travel lanes for heavy equipment.

I. Contractor shall monitor tree health throughout the construction process and notify

Project Manager immediately of any damages to trees as a result of construction activities. Contractor shall not implement any tree care practices without approval from

J. Trenching & Tunneling:

Section 01560 - 23

1. When trenching is utilized, it shall be done as far from the tree trunk as possible.

For trees less than 7” in diameter, trenching should be avoided under the dripline.

A general guideline for a minimum trenching distance is .5’ for each inch of trunk diameter measured at 4.5’ (dbh). The following table lists minimum distances for tree diameters:

Tree diameter

(dbh-4.5’)

Minimum trenching distance from trunk

10-12” 5-6’

14-16” 7-8’

18-20” 9-10’

22-24” 11-12’

26-28” 13-14’

30-32” 15-16’

2. In some cases, trenching inside of the minimum distance is unavoidable. When roots greater than 2” diameter are encountered while trenching inside of the minimum distance, equipment operation shall cease and roots shall be exposed by hand digging. Roots shall then be pruned cleanly with a saw to the depth of the required excavation, and on the edge of the trench closest to the tree. No root pruning shall take place without Project Manager’s supervision.

3. Soil removed from the trenches shall be replaced as soon as possible. Exposed, pruned, or broken roots shall not be allowed to dry out prior to final backfill.

Building materials, compacted soil, or soil with a permeability significantly different than the surrounding natural soil shall not be used to fill trenches.

4. Where feasible, a combination of trenching and tunneling may be utilized.

Trenching may be used in gaps between trees where root damage is not an issue.

When the trench approaches a tree’s root zone, tunneling may be implemented until safely out of the root zone. Another guideline is to replace trenching with tunneling when roots 1” in diameter are encountered. The following table lists some tunneling distances for tree diameters:

Tree diameter Minimum tunneling distance from any side of tree

6-9” 5’

10-14” 10’

15-19” 12’

Over 19” 15’

5. Tunneling is the preferred method over trenching for root protection. Tunneling at a minimum depth of 2’ is recommended; 3-4’ is safer. It is best to tunnel at least 1-2’ away from the tree trunk in order to avoid a conflict with a taproot.

K. Grade changes in root zones can cause significant damage and death of trees. Raising the grade can suffocate roots; lowering the grade can be detrimental as valuable feeder roots are destroyed. If enough larger roots are removed, the tree may pose a risk from reduced stability. Changing the grade within the root zone of any tree on the site shall be avoided and shall be approved by the Project Manager.

Section 01560 - 24

3.05 TURF PROTECTION AND RESTORATION

A. Contractor shall minimize disturbance and impacts to turf areas. Precautions shall be taken to prevent rutting, scalping and excessive compaction outside the excavation limits.

Mats, plywood or thick mulch may be used with the Project Manager’s approval, to prevent rutting.

B. Turf damaged by Contractor’s activities shall be filled, as required, with good quality top soil, graded and lightly compacted to match existing contours. Damaged areas shall be reseeded with grass seed suited to the local climate using hydro seeding methods.

Contractor shall provide a submittal for the seed mix and furnish seed label to Project

Manager.

C. Contractor shall provide all final restoration Work and clean up. Sweep all paved areas, rake all lawns, and remove all debris from the job site. Wash and provide final cleaning of all Work as directed by the Project Manager.

3.06 DEWATERING AND WATER CONTROL

A. Maintain excavations free from water while construction is in progress. Keep trenches and other areas free from water as required to permit continuous progress of, or to prevent damage to, the Work or the Work of others. No dewatering equipment shall discharge into area streams at any time, for any reason.

B. The Contractor shall not divert storm drainage or sewer flow through any portion of new sewer or any other new facility until after that portion of the pipeline to be used has been field-acceptance tested in accordance with the Specifications, and until specific written approval from the Project Manager has been received. No direct water from construction activities shall be diverted to new or existing sanitary sewer.

3.07 FISH AND WILDLIFE AND PLANT HABITAT

A. The requirements of local, state, and federal agencies charged with wildlife and fish and plant protection shall be adhered to by the entire construction work force.

B. ALL EQUIPMENT TO BE USED IN THE WORK SHALL BE CLEANED PRIOR TO

MOBILIZATION TO THE SITE to prevent noxious and non-native seed contamination of the site.

3.08 EROSION CONTROL

A. Execute the approved Erosion Control Plan.

B. Temporary Sediment Fences:

1. Filter fabric fence shall have a minimum 6-inch horizontal and 6-inch vertical burial for stability. All excavated material from filter fence installation shall be firmly re-deposited along the entire trenched area on the uphill side of the fence.

2. The filter fabric shall be installed to follow the contours where feasible. The fence posts shall be spaced a maximum of 6 feet apart and driven securely into

Section 01560 - 25 the ground a minimum of 24 inches. Overlap filter fabric fence joints minimum

12-inches prior to backfilling.

3. Sediment fences shall be inspected by the Contractor immediately after each rainfall and at least daily during prolonged rainfall. Any required repairs, relocations or additions shall be made immediately.

4. At no time shall more than one foot of sediment be allowed to accumulate behind a sediment fence. Sediment should be removed or re-graded into slopes, and the sediment fences repaired and reestablished as needed.

C. Straw Bale Sediment Barrier/Bio-Filter Bags: This method may be used to divert runoff around active Work areas or into sediment filtration/sedimentation areas.

1. Bio-filter bags can be used in drainage ditches and/or swales.

2. Straw bales and bio-filter bags shall be secured with stakes driven through them and into the ground to a minimum depth of 12 inches. Straw bales shall be keyed into the existing ground 2 to 4 inches.

3. At no time shall more than one foot of sediment be allowed to accumulate behind a straw bale sediment barrier and/or bio-filter bag system. Sediment should be removed or re-graded into slopes, or new lines of barriers installed uphill of sediment-laden barriers.

D. Plastic Sheeting:

1. Spoils piles and exposed earth slopes shall be covered in wet weather or if wet weather is anticipated. Plastic sheeting shall be installed and maintained tightly in place by using sandbags or tires on ropes with a maximum 10 feet grid spacing in all directions. All seams shall be taped or weighted down full length and there shall be at least 12-inch overlap of all seams. For seams parallel to the slope contour, the uphill sheet shall overlap the downhill sheet. No runoff shall be allowed to run under the plastic covering.

2. Drainage from areas covered by plastic sheeting shall be controlled such that no discharge occurs directly onto uncontrolled, disturbed areas of the construction site.

E. Excavated materials shall be placed on the uphill side of the excavation except when there are overriding safety requirements or lack of available space. In no case shall excavated material be placed in streams, watercourses, or wetlands without required permits.

F. Vegetative Buffer Protection: Areas within or adjacent to the project may have steep slopes, or buffers of associated streams, watercourses, or wetlands that need to be avoided and protected from disturbance. The Contractor shall limit disturbance to existing vegetation in these areas to the extent possible. In no case shall the Contractor cause disturbance in associated streams, watercourses, or wetlands without required permits.

Section 01560 - 26

G. Under no circumstance shall Contractor’s vehicles or equipment enter a property adjacent to a stream, watercourse, or other storm and surface water facility, or a wetland without an Erosion Control Plan having been approved by the Project Manager and implemented.

H. The Contractor shall not drag, drop, track, or otherwise place or deposit, or permit to be deposited, mud, dirt, rock or other such debris into any part of the public storm or surface water system, or any part of a private storm or surface water system. The Contractor, at the Contractor’s expense, shall immediately remove any such deposit of material. No material shall be washed or flushed into any part of the storm or surface water system without erosion control measures installed to the satisfaction of the Project Manager.

I. The Contractor shall maintain the facilities and techniques contained in the approved

Erosion Control Plan so as to continue to be effective during the construction or other permitted activity. If the facilities and techniques approved in an Erosion Control Plan are not effective or sufficient as determined by the Project Manager, the Contractor shall revise the plan upon notification by the Project Manager. Upon approval of the revised plan by the Project Manager, the Contractor shall immediately implement the additional facilities and techniques. In cases where erosion is occurring, the Project Manager may require the Contractor to install interim control measures prior to submittal of the revised

Erosion Control Plan.

J. The Contractor shall ensure that all necessary pollution control equipment, supplies, or materials are available to implement the Erosion Control Plan.

K. Filter fabric fences, sediment barriers and other erosion control devices shall be removed by the Contractor when they have served their useful purpose, but not before the upslope area has been permanently protected and stabilized.

3.09 CULTURAL RESOURCES

A. Attention is directed to the National Historic Preservation Act of 1966 and 36 CFR 800, which provide for the preservation of potential historical, architectural, archaeological or cultural resources (hereinafter "cultural resources").

B. The Project Manager intends to conform to the applicable requirements of the National

Historic Preservation Act of 1966 as it relates to the preservation of cultural resources and fair compensation to the Contractor for delays resulting from such cultural resources investigations.

C. Monitoring: No monitoring is required at the time of bidding.
