S2Li senior staff members have provided engineer of record services for Seminole County’s Osceola Road Landfill since 1985. In this capacity, we have assisted the County in the development of over 50 years of disposal capacity, as well as a number of ancillary operations that allow the facility to effectively meet the needs of the County’s residents.

Noteworthy services provided during this period have included encasement of a previously unlined landfill within a 232 acre slurry wall, performance of a borrow material assessment, development of an erosion control plan that provided for a vertical expansion of the facility, emergency stormwater management services to deal with a summer when rainfall exceeded 100 inches, performance of a contamination assessment that showed the site to be release free, assistance in the review of privatization proposals, in which the County staff prevailed in a managed competition approach, implementation of an active landfill gas management system in conformance with clean air act requirements, development and renewal of the site’s solid waste operations and Title V permit applications, initial development and subsequent expansion of a twenty acre yard waste processing area, development of a comprehensive site operations manual, and compilation of a 40+ year phasing plan that allows for maximum use of available disposal capacity while taking advantage of settlement that has and will occur during the remainder of the operating period.
