HJW Geospatial Awarded Fresno County, CA Landfill Mapping Contract

Oakland, California, January 16, 2006 – HJW GeoSpatial (HJW), Inc., has been awarded a three-year contract to provide landfill mapping services for the Fresno County, CA, Department of Public Works and Planning Resources Division. HJW’s aerial surveys will be used to determine calculations for fill and excavation quantities and/or subsidence for four landfill sites in the County.

Among the services for this contract, HJW will fly aerial photography at a photo scale of 1”= 600’ (1:7200) for the support of 1”=100’ scale mapping with 2’ contours. The topographic digital terrain data will allow HJW to perform surface and volume calculations to support the County’s landfill management.

HJW has extensive landfill mapping experience, and currently has ongoing contracts with Allied Waste (formerly BFI), Sonoma County, Yolo County, and Republic Landfill. HJW has also done rigorous landfill mapping for the City of Palo Alto, CA.
