Work in coordination with the California Department of Transportation (Caltrans) to enlarge and enhance 0.206 acre of existing seasonal wetland habitat adjacent to an unnamed stream along an established riparian corridor in Bothe Napa Valley State Park. The Department of Parks and Recreation will administer a contract to prepare the site, plantings, and initial maintenance of the site during plant establishment. Caltrans will provide biologists for construction oversight and conduct three years of annual monitoring, including quarterly and annual reports for condition and success; DPR will maintain the site after the monitoring period. Work will lower the existing grade approximately six inches using hand tools and a small Bobcat or other piece of equipment to increase soil saturation and ponding duration; remove non-native invasive plant species; restore native plants, including oak tree saplings, existing native wetland vegetation, and riparian trees. Work will proceed carefully to protect and preserve the oak woodland, oak root systems, and associate riparian vegetation. Tree plantings will consist of locally collected stock that has been nursery-raised to at least gallon size. This project allows Caltrans to satisfy California Department of Fish and Game, Regional Water Quality Control board, and U.S. Army Corps of Engineers conditional permitting requirements while restoring a wetland habitat in the State Park.
Project consists of minor public or private alterations in the condition of land, water, and/or vegetation which do not involve the removal of healthy, mature, scenic trees except for forestry or agricultural purposes included as "resource management projects" in the Department of Parks and Recreation's list of exempt activities in accordance with CCR § 15300.4.
