Keystone’s environmental group regularly prepares permit documents for the submission of stream and wetland impact permits necessary for construction projects. Keystone scientists compile field data and prepare Wetland Delineations and Stream Identification Reports that include a description of site aquatic resource features, photographs, data forms, and associated figures. Keystone performs threatened and endangered species reviews and obtains cultural and historic resource clearances as required or requested by clients for any type of development project. During environmental field reviews, crews investigate project areas for the presence of invasive species and provide location and prevalence of these species in an Invasive Species Report if they are identified.
