1.1. PROJECT INFORMATION

This project entails the required efforts to ensure the existing storm water management pond continues to meet its intended function. The pond is located at the U.S. Geological Survey National

Center, 12201 Sunrise Valley Drive, Reston VA. The pond and associate embankment were constructed when the building was built in 1972. Extensive repairs to rebuild the pond and embankment were completed in 1992. A copy of the plans for the rebuild are available upon request.

The site and pond are federally owned property. It is adjacent to Sunrise Technology Park. The area around the pond is relatively clear.

To be considered successful, the Work shall

• Deliver the project on time and within budget.

• Meet all project milestones.

• Establish and maintain positive relations with public authorities, jurisdictions, and neighborhood.

• Ensure a safe work environment during construction for workers and authorized visitors on the construction site.

• Manage the completion of the project with the spirit of partnering.

• Provide timely reports and communications.

• Ensure that all sensitive documents are handled, distributed, archived, and destroyed according to established project procedures.

1.2. ROLES AND RESPONSIBILITIES

2. SCOPE OF WORK (SOW)

2.1. DESCRIPTION OF WORK

The U.S. Geological Survey (USGS) Headquarters Campus requires services necessary to restore the stormwater retention pond to its original design capacity and functionality. Located at the USGS

National Center, 12201 Sunrise Valley Drive, Reston, VA, the approximately 0.3-acre wet pond is part of the facility’s Municipal Separate Storm Sewer System (MS4). This pond supports both peak discharge control during storm events and pollutant reduction in compliance with MS4 permitting requirements.

Accumulated sediment and overgrowth have diminished the pond’s capacity and performance. This project entails all routine and non-routine efforts required to return the pond to full operational status in accordance with federal and state stormwater regulations.

Regulatory Compliance

• Perform all work in accordance with the Virginia Department of Environmental Quality

(VADEQ) regulations for wet pond rehabilitation under the MS4 program.

• Comply with applicable requirements outlined in the Virginia Erosion and Stormwater

Management Program (VESMP), the Virginia Stormwater Management Handbook, and the

Virginia Stormwater Management Program (VSMP).

• Complete all routine and non-routine efforts activities required under these regulations, including maintenance of mechanical and structural components.

Nutrient Removal Calculation

• Calculate and provide estimates of nutrient loading reductions resulting from the dredging activities. This shall include:

1. Total Nitrogen (TN) and Total Phosphorus (TP) load reductions, expressed in pounds per year (lbs/year).

2. Estimate change in nutrient load reduction resulting from project.

3. Assumptions, calculation methods, and data sources must be documented and submitted as part of the final project report.

4. Provide total volume of sludge removed in cubic yards.

Sediment and Vegetation Removal

Remove excess accumulated sediment from the pond to restore its designed depth and capacity.

Take care not to disturb or damage any existing pond liner or the underlying silt or clay base. The contractor must measure and report the amount of sediment removed to the project manager.

• Remove:

1. Leaf debris and cattails from the pool area

2. Woody vegetation and trees from the pond embankment

3. Non-native vegetation within and surrounding the pond

• Inspect and restore the trash rack on the inlet structure to proper condition.

• Replace the riprap downstream of the inlet headwall as needed.

Mechanical and Structural Maintenance

• Inspect, maintain, and repair existing mechanical elements such as:

1. Valves

2. Sluice gates

Back to Top

3. Locks

4. Access hatches

• Maintain and restore existing plantings and any newly installed vegetation related to the pond restoration.

Site Protection and Restoration

• Identify and avoid any underground or above-ground utilities during all project activities.

• Repair any damage to roads, sidewalks, structures, or other infrastructure caused during construction.

• Ensure all workers are briefed on and comply with plant protection measures.

• Restore any disturbed landscape around the pond to its original condition or better.
