(340 enrolled members) • Approximately 20 Stillaguamish employees impacted. • Arlington to Darrington drive went from a ½ hour to over 2 hours each way. Fuel expenses more than doubled. • Many people sought alternate accommodation
Emergency Access Road • A 1.8 mile emergency access road was immediately identified along Seattle City Light power lines. • It was “improved” for trucks and emergency equipment within 1 week of the mudslide.
Emergency Access Road Emergency Access Road
Emergency Access Road 1,400 foot gap in the road. Gap filled in 20 continuous working hours. Approx. 10 – 12,000 CY of material. Steep grade (18%) is asphalt.
Emergency Access Road Two teams meet at the creek
Emergency Access Road Portions of SR 530 were found along base of the hill
Emergency Access Road/WSDOT • Emergency vehicles only for one month • Public desperate for alternate route because the detour added hours of daily travel time • Community meetings • “Who is going to unbury my property?”
Emergency Access Road
Mostly improved by locals with logging background, no plans, turnouts built for sight
distance throughoutEmergency Access Road Opens to the Public • Before the public could use the Emergency Access Road - One Party held out, word spread, problem resolved • Road opened to local public only
Community Transit (10 passengers per day in the first week of operation)
Could the Stillaguamish Tribe Contribute to the
Recovery Effort?
Indian Reservation Road Inventory - 2013
Oso MudslidePossible Funding Sources to Help Contribute to the Recovery
Tribal High Priority Projects Program (HPP Program)HPP Program • Matt Bohmert – Rick Larson’s office. They didn’t know what IRR or HPP was at first. They said they were in close contact with Patty Murray’s office with the Mudslide disaster. • Sally Hintz in Maria Cantwell’s office “call Mary Pavel”. • Mary Pavel – Staff Director of US Senate Committee on Indian Affairs holds a conference call with her staff and the Stillaguamish Tribe. “HPP exists but it’s not funded and won’t be until the fall, if at all. You could use your IRR allocation.”
Emergency Relief for Federally Owned Roads
(ERFO)ERFO • ERFO – Emergency Relief for Federally Owned Roads – • 1st Communication with Dave Hilgendorf, Western Federal Lands, FHWA - “SR 530 is a State Route and on the National Tribal Transportation Inventory (AKA - IRR Inventory). We will look into this and get back to you.” • Kyle Kitchel – FHWA calls later. “Because SR 530 is on the IRR Inventory, ER will pay for 100% of the ER funded portion of the rebuilding project.” • Dave Hilgendorf, later communication – “The 100% funding from FHWA (not the 86.5% as originally thought) is not a waiver, a discretionary issue or a gift, it’s a regulation.”
SR 530 Reconstruction Schedule
(All dates and costs subject to change)
ER Funds
$3.4 mil
(Removal of approx. 100,000
FEMA Funds
cys of mud and debris)
$4.9 mil
ER Funds
$20.57 mil• Main Point – Because SR 530 is on the IRR Inventory, FHWA (Emergency Relief) will pay 100% amount of the emergency access road and the rebuilding cost (not the normal 86.5%) • State and Local agencies will not have to pay the 13.5% cash match (or about $3.23 million) • FEMA pays for the debris removal
Side Issues • One victim worked on creating “Freedom County” by separating from Snohomish County • Some were saying “there are too many land use regulations in Snohomish County”. Went through the initiative process. Did not pass. • YET, there are several Mudslide law suits charging Snohomish County/Washington State for not protecting people from dangers
