General Project Description

This Request for Proposals is for wildland fuels reduction work at the Tilden Merry-Go-Round and Tilden Golf Course units. The project aims to reduce hazardous wildland fuel loading in forested areas through extensive use of large felling and biomass-processing equipment. The work involves technical, environmentally sensitive vegetation management, including tree and shrub removal, chipping, mastication, and off-site hauling of biomass. Advanced techniques such as climbing, rigging, and crane operations may be required due to large trees near sensitive resources or power lines. Public safety and protection of sensitive habitats, wildlife, and existing infrastructure (roads, trails, utilities) are paramount, requiring strict traffic control and environmental best management practices.
