3.1.6 Protection of Existing Vegetation

In areas where the design fill template would cover existing vegetation greater than 25 square feet in area, the Contractor shall avoid impacts as much as possible or as directed by the Contracting Officer. In these areas, the Contractor can slope down at 1V:3H to existing grade so that existing vegetation is not covered as much as practicable

3.2 PROTECTION OF EXISTING HARDBOTTOM AND CULTURAL RESOURCE AREAS

The Contractor must adhere to Dredge and Vessel exclusion outfall avoidance zones and "no dredge or work areas" shown on Plans. All mobilization and

SECTION 35 20 25 Page 17 demobilization activities and vessel usage during the project into and from the project area shall occur through the ingress/egress corridor which shall be field located and verified by scientific divers relative to the hardbottom survey in the drawings to avoid impacting existing hardbottom areas during pipeline laydown. No floating (individual or rafted) equipment is allowed over hardbottom and/or reef areas. The Contractor shall not anchor, place spuds, lay pipeline or place any other object on the hardbottom or within the cultural buffer zone. The Contractor shall operate vessels other than survey or crew boats solely within the ingress/egress corridor which shall be field located and verified by scientific divers relative to the hardbottom survey in the drawings to avoid impacting existing hardbottom areas during pipeline laydown. The Contractor shall train all subcontractors and work crews involved with dredging, pipeline installation, and equipment movements and storage on the procedures to be used to avoid impacts to offshore hardbottom communities and identified cultural resources. The training shall include methods or procedures to be used to avoid impacts and insure hardbottom and cultural resource protection. If damage to hardbottoms is detected, the damage shall be reported to the Contracting Officer immediately. The Contractor may be required to perform mitigation for unapproved substantial impacts to hardbottoms at no cost to the Government.

3.3 EXCAVATION

3.3.1 General

All excavation for beach fill shall be performed within the limits and depths of each borrow area shown on the drawings. Borrow areas provided for each fill segment are permitted for that particular beach fill segment and cannot be used interchangeable between project fill segments. Existing conditions of the borrow area are represented on the hydrographic survey and core boring logs in the Geotechnical Data Report (See Section 01 11 00 SUMMARY OF WORK). Excavation shall be performed in a uniform and continuous manner so as to avoid creating multiple holes, valleys, or ridges. If continuous reaches of rock are encountered in the borrow area, the Contractor shall change the location and depth of excavation within the borrow limits when necessary to provide the best fill material available at no additional cost to the Government. The Contractor shall remove no material deeper than the maximum elevation shown on the plans for each area of the borrow area. The Contractor's dredge equipment may extend and disturb material below the maximum excavation depth, provided that the post construction survey of the borrow area does not show that material was removed below the maximum excavation depth. The location of unsuitable material encountered within the borrow area shall be noted on the Contractor's Quality Control Report (copy appended to the end of Section 01 45 05 DREDGING/BEACH FILL PLACEMENT - CONTRACTOR QUALITY CONTROL). If the Contracting Officer determines the quality of beach fill is being adversely affected, that location shall be avoided in future passes of the dredge.

3.3.2 Borrow Area Characteristics

The characteristics of the materials in the borrow areas may be as generally indicated by the sediment boring logs and grain size distribution curves area located in Section 00 31 32 GEOTECHNICAL DATA REPORT (GDR).

The descriptions of the material found within the GDR are based on the site investigations and core borings and only describe the materials obtained from those investigations. The Contractor is solely responsible for any interpretation or conclusions drawn therefrom. The Contractor may visit

SECTION 35 20 25 Page 18 the location to view the core samples prior to the start of construction.

The Contractor shall provide a five (5) day notice to the Contracting Officer or their represent agent of their requested visit. The material found in each of the borrow area sediment core borings (vibracores) is indicative only of the sand at that discrete location. The CONTRACTOR should be aware that it is possible for material of differing characteristics to be present in the borrow areas, including material differing from that contained in the vibracores.

3.3.3 Borrow Area Dredging

The borrow area and each subdivision, unless otherwise directed by the Contracting Officer shall be completely excavated to the target depth before relocating the dredge to another borrow area or subdivision.

Excavation shall be performed in a uniform and continuous manner so as to avoid creating multiple holes, valleys, or ridges. The borrow area shall be dredged to maximize the removal of sand from each sub-area of each provided borrow area. The purpose of this requirement is to avoid "wasting" sediment which could be used to renourish the beach now and in the future.

3.3.4 Overflow Dredging

Overflow is considered a part of the dredging process and is permitted…
