BRIGHTON FLATS DEVELOPMENT PROJECT
Project Name: Brighton Flats Development Project, Denver, Colorado
Date Project Began: April 2005
Date Project Completed: July 2005
Project Description: Casey Resources, Inc. (CRI) completed an environmental site assessment in support of a Voluntary Cleanup Plan (VCUP) Application for the development of a two acre site in a former industrial area in Northeast Denver, Colorado. The results of the investigations indicated that the site's primary environmental problem was the existence of 10 to 20 feet of landfill debris containing a large volume of organic materials (grass and hay), which based on in-situ testing was generating significant levels of methane gas. CRI recommended the building architects incorporate environmental remediation aspects of construction into site planning such as foundation venting and proper management of water and excavated soils during construction. Based on the investigation findings, the building plans were modified not to include underground parking, but to construct slab on grade structures with methane venting systems. CRI provided methane venting system drawings as well as installation costs. CRI recommended the client consider development of a Voluntary Cleanup Plan Application should the proposed development include significant soil handling or removal.
Type of Contamination: Volatile Organic Compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), and metals contaminated soils and VOC impacted groundwater. Landfill deposits generating methane.
