The majority of the restoration work is removal of soil. After the soil is removed, more tests will be performed to ensure it meets the most stringent standards set forth by the Environmental Protection Agency (EPA) for residential development.
Geologic cross-sections are diagrams in which geologic formations and other geologic information are shown in a vertical section.
Approximately 400 acres of the 2,200 acres on the property require remediation and clean-up. There has never been any industrial activity on the remainder of the site, most of which has remained virgin desert. The evaporation ponds are now inactive. The soil underlying the ponds will be excavated and transported to a lined and monitored Corrective Action Management Unit(CAMU), off site. No excavated soils will be disposed of on-site.
The new master planned community will feature 526 acres of parks and open space adjacent to the Las Vegas Wash, the River Mountain Loop Trails and the Henderson Birding Preserve offering residents a multitude of outdoor recreational opportunities.
The Muddy Creek formation underlies the Qa. The Muddy Creek formation underlies much of the Las Vegas Valley and is more than 2,000 feet thick in places. The upper portion beneath the site is referred to as TMCf. The soil of the TMCf underlying the site is typically fine-grained (sandy silt and clay silt), although layers with increased sand content are also sporadically encountered.
