Cal-ISO Headquarters

Folsom, California

Foothill Associates’ ISA certified arborists conducted an arborist survey on the 33-acre California Independent Systems Operator (Cal-ISO) headquarters site in Folsom. More than 150 trees were inventoried, including native and non-native trees, following the City of Folsom’s Tree Preservation Ordinance. Tree data were recorded with GPS and mapped on an aerial photograph. The arborist report included recommendations for tree removal, maintenance, and protection during construction. Our arborists met with the City arborist on-site to review the report and proposed tree impacts. During construction we monitored pruning of all protected oak trees and work occurring within the critical root zone.

 

Biologists also conducted a biological constraints survey of the property to assess suitability of the property to support special status species and sensitive habitats.
