Haul Route And Staging Areas20
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
21
Fire Road22
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
23
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
24
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
