6.0 GENERAL SITE CONDITIONS

6.1 Site Access: A gravel and dirt road leads into the general site area. From there, a dirt and grass path leads to the dam. Keep vehicles on, or to the right of, that path. The area to the left of the path is always soft and vehicles will get stuck in the mud.

6.2 Health and Safety:

6.2.1 Proper Precautions: The Contractor shall take proper health and safety precautions to protect the work area, contractor’s personnel, the public, NPS employees and volunteers, other contractors that may be working nearby, and the property of others. This includes COVID-19. The Contractor shall be responsible for all damages to persons or to property that occur as a result of the Contractor’s fault or negligence. The Contractor shall abide by all OSHA regulations applicable to work under this contract. Additionally, the Contractor shall abide by all National Park Service, federal, state and local regulations that apply. Safety is paramount.

6.2.2 Protection of the Public: The Contractor will provide and install construction tape or other safety barriers, as appropriate, to identify, delineate, and separate the work area from public access. The system will control vehicular, bicycle, and pedestrian traffic, as necessary, without preventing access by emergency vehicles. NOTE: Except where specifically authorized in Section 8.0, no stakes, posts, rods, or other devices may be driven into the ground to support construction tape or fencing. Contractor must use free-standing stanchions, barrels, or similar devices. See, also, Section 6.3.

6.2.3 Care of Government Property: The Contractor shall conduct his operations in such a manner as to ensure against any careless or negligent acts that result in damage to Government property. The Contractor shall be held financially liable for any damage to Government property or buildings.

6.2.4 Safety Meetings: At a minimum, the construction supervisor shall conduct weekly 15 minute “toolbox” safety meetings. All construction personnel shall attend, and topics should coincide with work scheduled for the following week. Document and submit meeting minutes to the CO and COR.

6.2.5 Insects, Snakes and More: Contractor personnel should adequately protect themselves from local species, the most common of which are listed here—this is not an all-inclusive list. Insect pests include mosquitoes, ticks, chiggers, black widow and brown recluse spiders, deer flies and mayflies (especially in the Jamestown area). Repellents containing deet are recommended. Venomous snakes include the water moccasin (found mostly near freshwater sources) and the copperhead. The canebrake rattlesnake has been spotted in nearby Hampton, VA, on at least one occasion, as well as an unconfirmed spotting in COLO, and an unconfirmed spotting in York County*. Snake chaps should be considered. Foxes and coyotes are seen occasionally. A black bear has been seen on rare occasion, especially in the James River section of the Park. Stay alert. Noise will usually deter these animals. Of course, any rabid animal poses a significant danger.

* Note: From the Virginia Department of Game and Inland Fisheries, 2011 Canebrake Rattlesnake Conservation Plan, Section H, Protection and Management: “Canebrake rattlesnakes are protected from collection, sale, or possession under the Commonwealth of Virginia’s Endangered Species Act. They are also protected from wanton killing by humans.”

Unless you are in imminent danger, DO NOT kill a snake, just move away from it and wait until it passes. If contractor personnel find a dead light/dark patterned snake, call Dorothy Geyer, COLO Natural Resource Specialist, cell 757-876-7689. She will collect it for further investigation by her and/or the state biologist. If it is in the road, please use a stick to move it off to the side so that it does not get run over again.

Fire ants have been observed in the area around the Werowocomoco dam.

6.3 Ground Disturbances: Excluding notching and grading described in Sections 8.6 and 8.7, any trenching or other ground penetrating/disturbing activity must be scheduled through the COR at least ten (10) business days in advance for consultation with and/or observation by the NPS Archaeologist/Cultural Resources Manager (CRM). This process may also include an additional 30-day review process by the State Historic Preservation Office (SHPO). The Contractor is responsible for meeting all requirements of the Miss Utility program. Additionally, in the event of any archeological finds or uncovering of human remains, cease work in that area immediately and contact the COR.

6.4 Site Cleanliness and Final Cleanup: The Contractor shall at all times keep the work area, including storage areas, free from accumulations of waste materials. Before completing the work, the Contractor shall remove from the work and premises any rubbish, tools, scaffolding, equipment and materials that are not property of the Government. Upon completing the work, the Contractor shall leave the work area in a clean, neat and orderly condition satisfactory to the Contracting Officer.

6.5 Hauling, Dumping and Recycling: The Contractor shall remove all waste materials from the Park, and conform to all local, state and federal regulations. Contractor will attempt to “reduce, reuse, and recycle” (or compost) to the maximum extent practicable. Provide the project manager with the total weight of materials removed from the Park--include the total weight that went to a landfill and the total weight that was recycled, by material type.

6.6 Protection of Site: The Contractor shall be responsible for all materials delivered and work performed until completion and acceptance of the entire work, except for any completed unit of work which may have been previously accepted under the contract.

6.7 Utilities: Government will not provide any utilities.

6.8 Restrooms: There are no restroom facilities available. Contractor must provide appropriate temporary accommodations.

7.0 CURRENT SITUATION

7.1 Dam Structure: Circa 2000, the previous landowner constructed a “homemade” earthen dam which contains varying types of debris including but not limited to rock, concrete, tree stumps, and suspected limited amounts of trash and building materials. This debris is both within and on top of the dam structure, but the extent is unknown. Soil was pushed from what is now the pond area to cover the debris and form the dam. Additional soil is believed to have been brought in from off site. There are no known design or construction drawings or other records. Park personnel are unaware of any Commonwealth regulator involvement with the dam. The dam is not listed in the US Army Corps of Engineers (USACE) National Inventory of Dams (NID).

7.2 Dam Failure: The dam failed on March 29, 2019. Additional sloughing and erosion have occurred since that time. The approximate extent and dimensions are shown on the drawings in Section 10.0. See also Sections 2.3 and 2.4.

7.3 Tree: There is one known tree within the dam (there may be others). The dam was built around it, and the tree was then cut off just below the crest of the dam. It is about 18-24 inches in diameter and is partially visible within the dam failure area. When facing downstream, it is on the left face of the failure, thus it is within the area to be graded (Photo 8, Section 9.0).

8.0 NOTCHING AND TEMPORARY STABILIZATION

8.1 Work Limitations: No mechanical equipment is allowed more than ten (10) feet downstream of the downstream toe of the dam. Any mechanical assistance for removal of debris beyond this line must be done by a winch based upstream of that line (or similar means). Protect all areas that constitute “original grade” outside of the dam area to the maximum extent possible (see Section 6.3).

8.2 Debris:

8.2.1 Dispose: Remove the following items from the site and dispose in an approved recycling center or landfill (see Section 6.5): all HDPE pipe sections* (including those still embedded in the dam and those washed downstream of the dam; sections are approximately 27 inches in diameter); the temporary stairs and railings leading into the pond area; various manmade materials (boards, cages, crates, etc) supporting pumping operations; trash (bottles, cans, plastic, non-concrete building materials, etc) exposed within the dam or uncovered during grading, including trash washed downstream by the dam failure (within 50 yards of the toe of the dam at the washout location).

*Note: HDPE pipe sections may be cut to simplify removal, however ALL debris, shavings, etc, created by cutting the pipe must be captured and removed from site.

8.2.2 Retain: Stockpile the following items in separate piles (by type) in the locations shown in Photo 3, Section 9.0: tree stumps and tree debris; rock and concrete larger than a softball; soil (including any mixed-in rock and concrete smaller than a softball).

8.3 Stormwater Protection: Once the debris is removed, install appropriate silt fencing and any other appropriate stormwater/runoff protection no more than ten (10) feet downstream of the downstream toe of the dam. It is permissible to drive fencing stakes into the ground within ten feet of the downstream toe, as this area is previously disturbed.

8.4 Pumping: Contractor will provide, operate and maintain pumps to remove water from the pond area, starting within five calendar days from Notice to Proceed and continuing until project completion and acceptance. NPS will maintain current water levels shown in Section 9.0 until contractor starts pumping operations. Contractor will coordinate with NPS in advance for timing of removal of Park pumps. Keep water pumped down to current levels to allow notching operations and maintain at that level to prevent outfall through the channel until work is complete. This will provide acceptable working conditions for the contractor and prevent unnecessary erosion during construction. Primary resupply sources to the pond are rainfall, springs and runoff drainage from areas upstream. The Park currently operates three pumps (two 4-inch and one 3-inch) for approximately 6-8 hours per inch of rain received to keep the water at the current levels. The pumps discharge through hoses fed through the outlet pipes and across the failed area to a point beyond the toe of the dam. These pumps do not have sufficient power to pump the water up and over the dam. Six-inch pumps have been used successfully to pump the water up and over the dam on previous occasions. To avoid discharge hoses in the work zone, six-inch pump(s) will be required.

8.5 Clearing: Any downed trees in the way of grading operations shall be moved to the stockpile area. Remove the tree discussed in Section 7.3 by cutting to a level at least six inches below the final finished grade of the new slopes (see Section 8.7). Remove the approximately 9-inch diameter cedar stump (and root ball) on the upstream face of the dam near the outfall pipes (Photo 1, Section 9.0). Clear only enough vegetation on the downstream face of the dam near the failed slopes to allow proper grading. Cut down the two trees (estimated 9-inch and 4-inch diameter) identified in Photo 5. Notify the COR ten calendar days before removing the root ball of the 9-inch tree so that archaeological monitoring by the NPS can be scheduled. Remove the stumps and root balls as part of the grading operation. Remove the small saplings only to the extent needed to grade the slope. Leave the remaining saplings in place to stabilize the existing slopes. Cut all vegetation removed into lengths not to exceed twelve feet and stockpile per Section 8.2.2.

8.6 Notching: Notch the upstream face of the dam to an elevation that matches the water level shown in the photos in Section 9.0 (approximately ten feet below the upstream crest of the dam). The base of the notch shall extend upstream at the same elevation to the edge of the water. Notch shall be six feet wide at the base and level across that width. See Section 8.7 for additional information for creating the notch between the upstream and downstream faces of the dam.

8.7 Grading: Grade the channel through the dam at a constant rate of decent from the notch elevation at the upstream face of the dam to the existing elevation at the downstream toe of the dam. Do not dig below the level of the existing channel base in the failed area. The floor of the new channel through the dam will be six feet wide from the upstream face to the downstream face, and level perpendicular to the direction of stream flow. Compact the channel floor prior to creating the waterbars and placing the geotextile fabric, as described in the next two sections. The sides of the new channel will be graded to a slope of 2.5H:1V or flatter. This may be accomplished by a combination of cut and fill, as appropriate. All fill areas must be sufficiently compacted to prevent settlement or sloughing. Minimize disruption to the upstream face of the dam outside of the six-foot wide channel base, as these slopes are currently stable. This may require adjusting the graded slopes to a steeper grade in this area. Coordinate with the project manager prior to working in this area so that he can be on site when you notch the upstream face of the dam (see Photo 4). Stockpile the excess soil materials (see Section 8.2.2) with a slope of 2.5H:1V or flatter.

8.8 Waterbars: Use excess soil from the grading operations to construct two soil waterbars across the full width of the channel, perpendicular to the path of stream flow. The intent is to create an area where water can pond, thus slowing the rate of flow and allowing sediment to settle out. Construct one waterbar in line with the toe of the dam. Construct the second waterbar at the mid-point between the upstream and downstream faces of the dam. Waterbars shall be one foot high after compaction of the soil. Compaction shall occur in six- to eight-inch lifts. The waterbars shall be at least one foot wide at the top.

8.9 Geotextile: Install non-woven geotextile fabric in the channel from the upstream end at the current edge of the water to a point ten feet downstream of the downstream toe of the dam. Geotextile shall be 12 feet wide (without overlaps or seams across the width), shall extend three feet up the slope on each side of the six-foot wide channel, and shall conform to the shape of the soil waterbars. A single piece of geotextile is preferred, but two pieces can be used if the upstream piece overlaps (on top of) the downstream piece by at least five feet, the overlap is at least six feet from any waterbar, and the overlap is maintained after placement of riprap. The length of the fabric shall run parallel to the length of the channel.

Geotextile fabric shall have the appropriate grab strength, puncture and trapezoid tear resistance, permeability (medium-low), permittivity and ultraviolet degradation resistance for this application. Secure the fabric such that it remains in place during the placement of the riprap. If pins are used, remove them as the riprap is placed, to prevent tearing.

Prepare surface on which the geotextile will be placed to a relatively smooth condition, free from obstruction, debris, depressions, soft or low-density pockets, erosion features or vegetation. Remove any irregularities to ensure continuous, intimate contact of the geotextile with the underlying surface. Fabric shall be laid smooth and free of tension, stress, folds, wrinkles, or creases.

8.10 Riprap: Provide and install a 50-50 mix (by volume) of Class I and Class AI riprap. All riprap will be placed on top of geotextile fabric, and all geotextile fabric will be covered by a single layer of riprap. Height of drop of riprap shall not exceed twelve inches. Construct a riprap water bar on top of the full width of the riprap at the upstream leading edge. Construct a second riprap water bar on top of the riprap at the upstream face of the dam that is the full width of the notch. Both riprap waterbars shall be eight to twelve inches high (above the top of the layer of riprap) and twelve to fifteen inches wide.

8.11 Seeding: All exposed soil on the channel slopes and the stockpile will be hydroseeded with Kentucky 31 to minimize erosion. Prior to hydroseeding, rake the surface to remove all rocks, concrete and other lumps so that NPS personnel can safely mow these areas after the grass is established.

8.12 Site Restoration: Upon completion of work, restore any and all adjoining areas to their pre-construction condition. Rake restored surface (see Section 8.11). Hydroseed any restored areas. Note that the area to the left of the dirt and grass path leading to and across the dam is usually quite wet, from the dirt and gravel entry road all the way to the failed section of the dam and should be disrupted as little as possible during construction. Use of protective mats during the construction period is authorized.

8.13 Mowing: Notify NPS at least 14 days prior to on-site work start. NPS will mow all currently mowed areas approximately 5-10 days prior to work start. After work start, contractor may, but is not required to, mow or weed-whip areas that impact the work zone. NPS will not mow area until after work completion.

9.0 PHOTOS

9.1 All photos were taken on April 23, 2020.

Directions to Colonial National Historical Park (COLO):

Yorktown Visitor Center (YVC), COLO Headquarters, and YVC/HQ Conference Room

For GPS:

1000 Colonial Parkway Yorktown, VA 23690

On the map:

The YVC entrance driveway begins at the intersection of the Colonial Parkway terminus and Ballard Street in Yorktown, VA. This “five-way” intersection is often referred to as Five Points.

At the site:

The Visitors Center is in the ground level section of the building.

The HQ conference room is in the basement of the YVC. As you walk toward the Visitor Center from the parking lot, there are concrete steps to the far left that will take you down to the HQ section of the building. If the inner door is locked and I'm not there when you arrive, use the intercom to be buzzed in. If no one responds, try knocking on the door.

Please note:

You are looking for the Yorktown Visitor Center, not to be confused with the Yorktown Victory Center (now known as the American Revolution Museum at Yorktown), a state-run facility about 2 miles away--people frequently confuse the two and wind up in the wrong place.

Tips for the Colonial Parkway:

1. Speed limit is 45 MPH in most places, but 35 and 25 in some locations.

2. Generally, there are no lane markings. This is part of the Parkway’s history, with the intent of making the road resemble the original dirt and marl roadway.

3. Generally, the Parkway is a three-lane road. Where designated, passing is allowed in both directions, using the center lane. Use caution and watch for oncoming traffic.

4. Some people are not aware of the three-lane concept and presume there is an imaginary centerline dividing the Parkway into just two lanes. Again, use caution.

5. Commercial vehicles are not authorized on the Parkway without a permit.
