WHAT WE KNOWWETLANDS
Based on delineation performed in2020, subject to US Army Corps ofEngineers review and approval.
High Value
Low Value
ISSUESToadstool Drive
• Girdwood Sign at Toadstool is an attraction,increases stopping/turning movements
• Traffic stopping at Toadstool, pedestrians runningacross highway to photograph Turnagain Arm
• Used as a bypass for intersection, creating moretraffic for local residents
Main Street• Used as a bypass for intersection by locals• Local street, not improved
Gold Avenue• Issue with accessing Alyeska Highway from Gold
Ave.• Old Girdwood townsite has to use the gas station
parking lot for through access
WHAT WE HEARDSTAKEHOLDER ENGAGEMENT SO FAR
Girdwood Station & Commercial Mall• Pedestrian/Bicycle traffic – kids, dogs, people,
especially at Alyeska/Gold Avenue pathway connection• 3 Driveways at Tesoro can cause conflicts• Mall access can be difficult• ROW is being used by vendors to sell seafood, other
itemsSafe ingress/egress for Trucks at Tesoro
• Creates situation where they park along the shouldersof the Seward Highway
• No dedicated parking for big rigsViewsheds to Turnagain Arm
• Do not block or change viewsheds for any alternative• Concerns about the area south of the highway• Desire for scenic view pullouts on Arm side of Seward
Hwy to address parking along shoulders
ISSUES (continued)Speeding along Alyeska Highway after turningoff of Seward HighwayJuly and December are the most congestedmonthsStrong opposition to gravel sourcing fromGirdwood Valley
OPPORTUNITIESRecreation use and need for safe parking orpullouts
• Tide lands for skating in winter• Fishing under Glacier Creek Bridge• Would like a boardwalk in the tidal flats
Non Motorized facilities• Consider a bike path connection (continue Bird to
Gird trail)• Coordination with National Historic Iditarod Trail
