The Flood/Ice Dam
A long cold winter combined with higher than usual snow pack (up to 150% of normal), higher than usual ice formation on the river (up to 140% of normal) and several days of unseasonably warm weather, which caused rapid melting and ice movement downstream on the Yukon

DOT/PF TOP PRIORITY
Provide SAFE, EXPEDIENT, low-impact vehicular access route to new Eagle Village.
EAGLE/ YUKON RIVER ICEJAM/ FLOOD MAY 09 DISASTER EVENT
Emergency Access Options
Initially considered cutting through ICE/Debris on Mission road – to create 24’ vehicular Road access NEGATIVE IMPACTS: $$$, potential for
damage to cultural /personal property embedded in ice; potential for high risk safety issues; potential to create more mess when ice thaws and fills into the roadway cut
Because of safety and potential for additional damage, decision was made to allow ice mass to thaw naturally until debris is retrievable and safer to remove. EAGLE/ YUKON RIVER ICEJAM/ FLOOD MAY 09 DISASTER EVENT
Considerations in planning alternate temp Vehicular
route
Looked at temp detours/alt routes for pre-fab road mat system which would lay down with minimal ground prep and min ground disturbance to wetlands. 2 viable routes:
Existing 4-wheeler trail that was being used, passable at the time only by 6-whlrs since it was getting more saturated daily due to high use and thawing ground. Trail was also very curvy and with lots of hills and dipsPreferred Option: Straight route determined along a survey line cut from east end of airport straight through to mission rd just south of village

Mission Road proposed temporary by-pass

The Ice Field
Detour Route
5.21 MAINLINE Completed with all mat quantities installed.• 400 Durabase (composite material interlocking semi-flexible)
• 200 MudMats (cordura-like fabric with sandwiched bamboo poles), Eventually OVERLAYED w/ DuraBase mats
• 100 Carolina (rigid wooden type) – also decided to replace these on the mainline with Durabase.
EAGLE/ YUKON RIVER ICEJAM/ FLOOD MAY 09 DISASTER EVENT
We were constantly focused on improving the safety and functionality of the detour route.
mudmats
EAGLE/ YUKON RIVER ICEJAM/ FLOOD MAY 09 DISASTER EVENT
Mudmats
ISSUES with Mudmats: bamboo “reinforcement poles” bend and break even after pickup truck driving over it; bicyclists cannot drive on it;, water is seeping through the fabric. Project was reluctant to allow trucks and heavy equipment to drive over mudmats.
Carolina Mats
ISSUES w Carolina mats: many of them shift quite noticeably and need heavy equipment to adjust after several passes of heavy vehicle traffic. Very rigid, do not flex to meet end to end without need for shims of lumber to bridge.

Next Step - Debris Removal
Debris removal contract and Rd repair contract with 5 day bid period (6/5)
Contractor started work 6/13
ADEC provided Term-Contractor for Hazmat removal
Worked with ADEC /DNR/SECC and City to locate debris storage site.
