TABLE OF CONTENTS

1 PROJECT INTRODUCTION

Project Name: York River Shoreline Stabilization

Project Number: COLO 253093 & 316317

Yorktown, VA 23690

1.1 Project Location

The project is in York County Virginia, a few miles northwest of Yorktown. This work is located along the York River shoreline parallel to Colonial National Historical Parkway in Colonial National Historical Park (COLO). The segment of work for this project is identified as Reaches 1 & 2 of the shoreline. Reach 1 extends from Felgates Creek on the west to Indian Field Creek to the east, a distance of approximately 1.7 miles. Reach 2 extends from the mouth of Indian Field Creek on the west to the pier of the Yorktown Naval Weapons Station to the southeast, a distance of approximately 1.4 miles. Government furnished draft design drawings provide more detail.

1.2 Project Description

This project will repair and stabilize portions of the York River shoreline in Reaches 1 and 2 that have been severely eroded. This stabilization is essential to prevent loss to the current alignment of Colonial Parkway due to shoreline erosion. The project includes a combination of shoreline stabilization and marsh protection in both reaches. The work will generally consist of adding rock to increase the revetment height, installing new rock sills and breakwaters, enhancing or adding wetland and marsh habitat, and slope stabilization. Sheet pile wall will be installed to stabilize the steep slope, reduce erosion, and protect the parkway alignment proximate to distance marker K5 (delineated in the plans), northwest of the Yorktown Naval Weapons station pier. Other steep slopes and erosion will be stabilized utilizing geotextile materials and/or native plantings. This slope stabilization is expected to protect shoreline slopes from stormwater runoff above as well as undercutting below. Note that project site access limitations require most material and equipment delivery and some installation of the work from the York River by barge.

4.1.4 Parking of Construction Vehicles

Parking of vehicles shall be limited to existing roads, in legally designated areas, and within approved staging area(s).

4.1.5 Special Construction Conditions and Requirements

In-Water Work Restrictions: The York River has been designated as and Anadromous Fish Use Area, and the federal and state endangered Atlantic sturgeon (Acipenser oxyrinchus) is identified by Virginia Fish and Wildlife Information Service (VAFWIS) as occurring within the river. As such, a time-of-year restriction (TOYR) on in-stream work is typically required from February 15 to June 30, particularly for activities that may generate excessive noise or increase turbidity.

Weight limitations and commercial vehicle restrictions exist for Colonial Parkway and associated bridges. Check requirements prior to shipping materials on these roadways. Rock and heavy equipment required to complete the work will be delivered via barge or other seaworthy vessel. Potential barge access points have been identified on the design drawings provided.

The hurricane season begins June 1 and terminates November 30. Should a hurricane threaten the area, the park shall be secured and closed at least 24 hours before anticipated storm landfall.

Any previously abandoned construction debris (not including trash washed ashore) discovered in the course of the project work that is clearly within the project area work zones shall be removed and disposed of properly. Known debris includes rusted steel ‘I’ beams adjacent to Felgates Creek, rusted steel buoys on the shoreline, and a beached log fender (aka log camel).

4.2 Access

Coordinate construction efforts with the CO such that there is minimal impact to the work of NPS personnel, the visiting public, and other contract work in the park. During construction of the scheduled facilities, the Contractor shall have continuous access to the site.

4.3 Working Hour Restrictions

All work and deliveries shall be limited to the weekday business hours of 7:00am to 5:00pm unless otherwise approved by the CO. No work shall occur on Federal holidays or weekends without prior approval.

4.4 Environmental and Sustainability Requirements for Construction The following are general environmental and sustainability requirements during construction, designed to minimize construction impacts.

4.4.1 Air

Employ construction practices that minimize dust production and combustion byproducts.

4.4.2 Water

Avoid materials that can leach toxic chemicals into the ground water. Do not allow toxic chemicals to enter sewers or storm drains. Submit a Storm Water Pollution Prevention Plan (Section 5.5.2) to the CO prior to Construction which meets local, state, federal requirements, and obtain all necessary permits. Apply Best Management Practices, including vehicle wash-down areas, protection of equipment storage and maintenance areas, and sweeping of roadways related to hauling activities.

4.4.3 Soil

Protect against erosion, contamination, and topsoil depletion.

4.4.4 Exotic Vegetation and Noxious Weeds

Prevent the introduction and minimize the spread of exotic vegetation and noxious weeds. Any fill, rock, or additional topsoil needed shall be obtained from a Government approved source. All areas disturbed by construction shall be re-vegetated using approved native seed and/or plants.

4.4.5 Vegetation Salvage and Re-vegetation Plan

A Salvage and Re-vegetation Plan shall be required for this project. Any re-vegetation efforts shall use approved native species and/or native seed, and park policies regarding vegetation and site restoration shall be incorporated into the plan. The plan shall consider, among other things, the use of native species, plant salvage potential, the avoidance of exotic vegetation and noxious weeds, and the use of pedestrian barriers.

4.4.6 Habitats

Protect natural habitats and ecological systems on facility site.

4.4.7 Special Status Species

To protect any unknown or undiscovered threatened, endangered, or special status species, the construction contract will include provisions for the discovery of such. The Contractor should contact the park for direction for evaluation of any special species at the site.

4.4.8 Noise

Minimize noise generation during construction. Operate power equipment in accordance with local noise restrictions.

4.4.9 Materials

Use resources efficiently. Select materials and use construction practices that achieve the most efficient use of resources and materials.

4.4.10 Waste Management Goals

Employ processes that ensure the generation of as little waste as possible. Minimize waste generation due to over-packaging, poor planning, breakage, mishandling, contamination, error or other factors. Of the waste generated, as much as is economically feasible shall be reused, salvaged or recycled. Waste disposal in landfills shall be minimized. All material unsuitable for recycling must be disposed of, in a legal manner, at public or private dumping areas outside the park.

Materials that may be recycled include but are not limited to the following:

· Cardboard, paper, packaging

· Clean dimensional wood, pallet wood

· Beverage containers

· Concrete

· Concrete Masonry Units

· Metals from banding, ductwork, piping, rebar, roofing, etc.

4.4.11 Air and Water Pollution Control

Air quality impacts are expected to be temporary and localized. All necessary and reasonable measures shall be taken to reduce air and water pollution by any material or equipment used during construction. To reduce tailpipe emissions, construction equipment shall not be left idling any longer than is necessary for safety and mechanical reasons. Volatile wastes shall be stored according to best industry practices and in covered containers.

4.4.12 Cultural Resources

Colonial National Historical Park contains subsurface archeological resources. If archeological resources (including human remains) are discovered at the project site, all work in the vicinity of the discovery must stop immediately, and the discovery must be reported to the CO. Work may not continue in the aera without explicit approval from the Park cultural resource staff and CO. While NPS does not anticipate the Contractor uncovering subsurface cultural resources in the project area, the potential exists.

The quality of all work shall be the responsibility of the Contractor. Inspect and test all work as needed to ensure that the quality of materials, workmanship, construction, finish, and functional performance is in compliance with applicable specifications and drawings. Quality Control Daily Reports shall be completed by the Quality Control Supervisor. Test reports shall be completed by person performing the test.

4.5.2 Quality Control Staff

The Contractor's Quality Control Supervisor may also perform the duties of Project Superintendent.

The Contractor's designated Quality Control Supervisor shall be on the project site whenever contract work is in progress. The Contractor's job supervisory staff may be used to assist the Quality Control Supervisor, supplemented, as necessary, by additional certified testing technicians.
