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
