The project included design of a geosynthetic clay liner for the barrier layer, erosion control and stormwater management, permitting, and construction observation and certification. The project also included installation of 30 gas vents, constructed through the in-place waste.
* Volusia County, Florida, Design and Permitting of an Expansion at the Tomoka Farms Road Landfill. Project Manager and Project Engineer for the design and permitting of a 53-acre expansion to the Tomoka Farms Road Landfill. The bottom liner design incorporated geocomposite drainage net in lieu of leachate collection pipe laterals.
*Flagler County, Florida, Landfill Evaluation. Project Manager and Project Engineer for the evaluation of a 284-acre parcel proposed for landfill construction in Flagler County. The project included evaluation of wetlands, potential for archaeological sites, and geotechnical investigation.
*Landfills have included Class I, Class III, Construction and Demolition Debris (C&D), and yard waste landfills. Project Manager and Project Engineer for numerous landfill expansion projects, including compacted clay liners, high density polyethylene (HDPE) liners, and composite liners.
*Project Manager for the closure of numerous municipal landfills in Central Florida. Closure designs have included soil covers, slurry walls, plastic membrane liners, compacted clay liners, and geosynthetic clay liners. Services have included planning, permitting, design, construction administration, and closure certification.
*Prepared Financial Assurance reports for numerous landfills including Volusia County, Seminole County, and private Construction and Demolition Debris landfills. Services performed included preparing estimates of remaining airspace and life and updating the estimated costs of closing and of post closure care.
*Tampa Electric Company, Polk Power Plan, Design and Construction of Replacement Liner. Project Manager for the design and construction of a replacement liner for the Tampa Electric Company Polk Power Plan coal slag storage area. The project required that the 2.7-acre double-lined storage area be able to remain in operation during the entire construction period.
