Alternative Delivery, Design/Build and Public Private Partnerships
3e brings a wealth of practical experience and unparalleled capability to address the environmental needs of Alternative Technical Concept (ATC), Design-Build (DB), and Public Private Partnership (P3) infrastructure projects. The key to our success has been the depth and diversity of our professional service offerings. We have effectively coordinated all of the environmental requirements of numerous design build projects from preliminary engineering through final construction including NEPA documentation, hazardous material assessment and remediation, natural resource evaluation including threatened and endangered species surveys, cultural resource coordination, mitigation strategies, storm water compliance and construction administration as it pertains to environmental conditions. 3e has developed the tools and protocols to ensure effective coordination with the Construction Contractor and Design Team from initial conceptual planning through final construction. This experience has allowed us to develop and refine a series of best practices for environmental due diligence, assessment of natural resources, obtaining all required permits and approvals in a timely fashion, development of special conditions that do not impede and impose undue costs on the construction, development of effective avoidance and minimization strategies, and maintaining compliance with permits and approvals throughout the construction process. We maintain excellent working relationships with the regulatory community and we understand all aspects of the various environmental requirements of the federal and state regulatory agencies.
I-64 Segment II Capacity Improvements, City of Newport News to City of Williamsburg, Virginia
The Project is the second segment of a 75-mile section of Design-Build roadway of Interstate 64 between Richmond and Hampton, Virginia that will complete capacity improvements that include travel lane reconstruction and addition, shoulder widening/strengthening, repair/widening of nine bridges and six box culverts, acceleration/deceleration lane extension, and construction of stormwater management facilities using value-engineering design and multiple VDOT reviews. To implement the 2013 FHWA/VDOT EIS/FONSI, 3e provided environmental and natural resources services for the contractors charged with construction of the 7-mile Segment II between Routes 199 and 238 on a 460-acre corridor through eastern part of the Williamsburg region. 3e completed the following tasks:
- Phase I Environmental Site Assessment to identify RECs, and performed Asbestos Containing Materials (ACM) Inspections and Bat Occupancy Inspections for bridges.
- Jurisdictional delineations and obtained a PJD for approximately 9.32 acres of wetlands of four cover types, and approximately 8,875 linear feet of 26 surface water channels.
- Threatened and Endangered (T&E) species studies and coordination documenting potential habitat status for state listed mole salamanders and listed bats and coordinated federally listed T&E species for the project area through the ESA Section 7 process.
- Landscape Design for the corridor, including plans for multiple stormwater management and bio-retention facilities, several miles of raised median, along the base of sound walls and retaining walls, and areas adjacent to properties where visual screening is needed. 3e provided a reforestation plan for two large contractor yards used on the project. Plans were developed through coordination with VDOT, the City of Newport News, City of Williamsburg, James City County and York County representatives, and guidelines set forth in Section 605 of the VDOT Road and Bridge Specifications.
- Construction Support Services including permit monitoring for erosion and sediment control and stormwater management, ACM project monitoring and lead-based paint (LBP) surveys for several bridges in the project area.
Route 3 Widening, Culpeper, Virginia

Odd Fellows Road Improvement & Route 460 Interchange, Lynchburg, Virginia
3e prepared the natural resources, wetlands and hazardous materials technical reports for this 3-mile roadway improvement and interchange project. The project area featured a complex mix of water resources and cultural resources. Under the project, 3e was responsible for the following:
- DEQ WVP, USACE Section 401/404 Individual Wetland Permits, Compensation and Monitoring

Route 58 Improvements, Hillsville to Meadows of Dan PPTA Project, Hillsville, Virginia
3e assisted the prime consultant with developing stream relocation/restoration design plans for a permittee-responsible mitigation site in Pulaski County to compensate for unavoidable impacts on the Route 58 E-02 and E-11 project located in the portions of Carroll and Floyd County that are in the New River drainage. The Pulaski mitigation site was active farmland that drains to an unnamed tributary of Bentley Branch, a perennial tributary to the New River. The topography of the site was gently rolling with deeply incised channels. The areas proposed for mitigation use and construction are active cattle grazing areas situated on existing compact stream terraces. These areas have limited to no woody vegetation, and stream channels are in various states of disequilibrium that require restoration to return the channels to a stable form such that existing accelerated bank erosion can be reduced. The stream terraces vary from very poorly drained areas in springs and depressions (former drainage ways) to well-drained alluvial deposits.
3e’s scope of work for this project included the following services:
- Coordination with Other Contractors and Regulatory Agencies
- Delineation of Streams and Wetlands
- Due Diligence (Threatened and Endangered Species Studies, Hazardous Materials Studies and Cultural Resource Clearance)
- Collection of Site Data
- Site Surveys
- Conceptual Plans
