Brevard County South Landfill Expansion – Cell 1

Jones Edmunds provided engineering services to design and permit the first cell – approximately 40 acres – of a new 220-acre Class I landfill. Jones Edmunds performed a preliminary engineering study to offer cost-saving options that included evaluating releasing conservation easements, various liner system and leachate collection system configurations, and cell size and location options. We performed stormwater modeling and wetland mitigation analysis for the 220-acre final buildout and the existing slurry wall landfill to obtain an ERP. To maximize landfill capacity and reduce the amount of imported fill required, the new cell’s bottom liner will be constructed up to 10 feet below the groundwater table. We developed a dewatering plan and on-site groundwater recharge specifications and operations that will minimize impact to the adjacent Slurry Wall Landfill. Jones Edmunds also performed a value-engineering study of the design to identify areas that could reduce the capital cost. We helped the County obtain a permit modification based on the value-engineering changes and provided bid-level documents. The $20-million expansion is the first lined landfill for the County.

New River Solid Waste Association EGC Closure Design and Permitting

Jones Edmunds provided the New River Solid Waste Association (NRSWA) with engineering services to modify the closure design and permit the closure with an exposed geomembrane cover (EGC) for the New River Regional Landfill (NRRL). The design and permit modification modified the permitted traditional closure design. The project included preparing a substantial permit modification to address the changes to the side-slope closure for an EGC closure. We prepared and submitted a substantial permit-modification application in accordance with Rule 62-701, FAC, including preparing the required supporting calculations and documentation for constructing the EGC for the closure.

Jones Edmunds worked closely with the NRSWA and the Florida Department of Environmental Protection (FDEP) to develop an Alternate Procedures Application for an Exposed Geomembrane Landfill Closure. Based on FDEP’s approval of the Alternate Procedures Application, Jones Edmunds submitted to FDEP a solid waste operation and construction permit application for an Exposed Geomembrane Cover (EGC) closure project. FDEP granted approval of the EGC application – this was first approved EGC closure permit in Florida. The conditions of the permit stated that an EGC would be installed as final cover until the material strength reached its half-life, at which time the traditional 24 inches of soil cover would be installed over the EGC.

The EGC is being constructed in phases as the landfill reaches final elevations. The EGC closure project includes preparing the final grade slopes, installing the geosynthetic material, and constructing the toe-drain system. The EGC closure project also included an evaluation of the gas collection and control system (GCCS) in the closure area. Phase I of the EGG project is approximately 15 acres. For Phase I, Jones Edmunds provided construction assistance including preparing bid and contract documents and coordinating Construction Quality Assurance (CQA) material testing and providing full-time CQA resident observation during construction.

Walton County Transfer Station

Walton County’s existing transfer station needed to be replaced because it was not ideally designed for this purpose and was nearing the end of its useful life. In addition, the existing facility was not well located on the County’s solid waste management site with respect to future solid waste management needs of the County.

Jones Edmunds worked closely with County staff to develop a Concept Plan for a new solid waste transfer station in concert with the County’s longer term goals and objectives for solid waste management. To provide more efficient management of solid waste by the County, Jones Edmunds developed recommendations for a more effective transfer station design and optimum location for the facility on the County’s solid waste management site. We prepared a detailed report that assessed the sizing needs for the new facility, evaluated three site location options and associated costs, and provided schematic drawings of the proposed site plans and the proposed building plan and elevations. Based on regulatory requirements, good engineering design, and input from County staff, Jones Edmunds incorporated the proposed design elements for the facilities including vehicle access and routing, operational needs such as breakroom and bathroom facilities, leachate collection and management, truck scale requirements, provision for electric power, access roadway and inbound scale facility, site paving and grading, building design to accommodate future expansion of the facility, stormwater management, provision for fire protection, extra trailer parking, and communication capabilities to other site facilities. The Concept Plan was presented to the County and draft format for review and comment. Upon discussion of County comments, the Concept Plan was finalized and approved by the County.

Following completion of the site Concept Plan, Jones Edmunds developed preliminary design documents for the civil site work and building architectural, mechanical, electrical, plumbing, and structural design for the Solid Waste Transfer Station Facility. The structural, mechanical, electrical, and plumbing design elements were prepared by subconsultant McVeigh and Mangum, and the architectural design was prepared by subconsultant WMB-ROI. Jones Edmunds also coordinated the preparation of site survey and geotechnical investigations through subconsultants for the project. Jones Edmunds worked with local City utilities providers to assess and provide for water and sewer service requirements for the facility. The work products consisted of construction drawings and technical specifications to the level necessary to prepare FDEP permit application packages consisting of Solid Waste Processing Facility Permit Application and Environmental Resources Permit Application for submittal to FDEP. Jones Edmunds coordinated reapplication meetings for both permits and coordinated with County staff. Both FDEP permits were received with minimal comments from the reviewers. We also prepared the FDEP water and sewer service connection permits, coordinating these applications and final design details with the City.

Upon confirmation of approved permit applications, Jones Edmunds developed Construction Bid Documents that include complete design drawings and specifications for Bidding and Construction. We worked with County procurement staff to develop the final bid documents for use in the bidding process.

Solid Waste Management

Every day the average American generates about 4.5 pounds of garbage. Addressing solid waste management is a critical infrastructure element for every community. In Florida with our shallow water table, we must protect our natural resources from the growing population and the waste it produces. Integrated solid waste management is the key to sustainably and cost-effectively managing waste, and we support our clients with the infrastructure it takes for them to provide this essential service:

  • Landfill and Bottom Liner Design
  • Transfer Station Design
  • Bioreactor Systems
  • Leachate Management & Disposal
  • Landfill Gas Management & Energy Generation
  • Recycling Studies
  • Compliance Monitoring and Management
