Solar Array at the ILR Landfill

This 7.7-MW solar power facility spans approximately 65 acres of sanitary landfill closed and capped in 1985. Langan provided complete surveying, site/civil, geotechnical, and construction observation services for the project, which was one of the first projects where Langan used unmanned aircraft systems to create the existing topography. We also provided geotechnical recommendations with respect to subgrade preparation and measures to mitigate against long term settlements.
