Leona Heights Sulfur Mine & Creek Cleanup 5 The Problem
The Problem : Acid Mine Drainage
The Problem : It’s Toxic to Wildlife Leona Creek: Not just ugly… Mercury Cadmium Copper Lead Arsenic 10 to 10,000 x levels toxic to wildlife (no pathway to humans)
The Goals, Actions, & Actors Agencies Involved Project Goals • Cleanup mine site, eliminate acid mine drainage • Cleanup Leona Creek • Minimize impacts • Disturbance of neighbors (dust, noise, traffic) • Tree removal • Wildlife • Water Board • Required and oversees cleanup, design, stream habitat protection • City of Oakland • Permits & environmental review (CEQA) • US Army Corps Engineers • Stream protection • Ca Dept. Fish &Wildlife • Endangered species & stream protection

Construction Management 18 • Staging Areas • Access Route • Logistics of Using McDonell Ave • Dust Control • Noise Control • Construction Days/Hours • Project Duration
Staging Areas • Primary Staging Area • McDonell Cul-De-Sac and Site Entrance • Materials Staging Area • Leona Lodge Overflow Parking Lot
Access Route • McDonell Ave. vs. Fire Road • Why not Fire Road? • Segments with Steep grades (up to 15%) • 180 degree Switchbacks • Appr0ximately 3.0 miles roundtrip • Shuts down trail for 5 months • Larger air emissions • Habitat for Alameda whip snake • Biological mitigation/Vernal Pools • Only emergency access • Need improvements to use • Still need to cross and use McDonell Ave
Access Route • McDonell Ave. vs. Fire Road • Why McDonell Ave? • Right at the primary staging area • Appr0ximately 0.6 miles from materials staging area • Paved road with gentle slope • Less air emissions • No biological mitigation • Do not need improvements to use • Reduced environmental impacts
McDonell Use Logistics • 5 Materials Staging Events • Each Event lasts 5 days (Monday~Friday) • Flagmen with radios to implement traffic control • Small Haul Trucks (with payload <10 tons) • Truck speeds to be kept under 10 mph • Residents will be given priority to truck traffic
Dust Control • Limited water spray to soils graded, excavated, truck loaded., etc. • Amount to control dust, but not cause runoff • Cover soil stockpiles with weighted plastic sheeting • Vehicles <5mph • Minimize material drop heights during unloading
Noise Control • Smaller Equipment • Noise Reduction Blankets on Perimeter Fence • Noise Reduction Blankets on Temporary Fence • No Construction Work at night, on weekends or holidays
Construction Days/Hours • Weekdays only (Monday-Friday) • Working Hours - In Accordance With City Of Oakland Conditions Of Approval • No Holidays
Project Duration • Construction Start • Early to Mid May 2014 • Construction Completion • September 30, 2014
