Project Info

Title

Yosemite Area Forest Restoration Phase II, Yosemite West

Description

This project is an identified project within the Mariposa County Tree Mortality Hazard Mitigation Project in a Tier 1 High Hazard zone. Hazard tree and downed tree removal work is critical to meet the public safety and fuels reduction needs stemming from widespread tree mortality in the southern Sierra Nevada, to complete the program of work (2016 Mariposa County Tree Mortality Hazard Mitigation Project) with the co-benefits that include protecting infrastructure and increasing public safety from debris flows and flooding damage due to high levels of biomass on erosive, fire damaged soils. It also protects communities located within the Wildland Urban Interface. The mitigation activities are needed based on a high density of dead or dying trees which threaten water and wastewater treatment infrastructure, powerlines, roads and other evacuation corridors, and other existing structures. The project will benefit Mariposa County residents and visitors, Mariposa County business owners, Yosemite National Park, the US Forest Service, CALFIRE and all emergency responders. The dead or dying trees included in this project are not healthy, mature or scenic trees based on their current condition. No ground disturbing activities will occur as a result of the project. No work will be done within the bed, bank or channel of any existing drainage within the project areas. Mariposa Resource Conservation District and Mariposa County have appropriately trained and qualified staff and/or contractors who have identified dead and dying trees. Dead or dying trees will be felled in a controlled manner to reduce hazards and biomass will be chipped onsite, piled and burned, or removed to a biomass disposal facility. If pile burning is needed, it will be completed in compliance with Mariposa County Air Pollution Control District permits.
