Corridor Concept Update Workshop #4
05.21.2019
TODAY’S AGENDA
• PEL Study process and planning context
• PEL Study status – where we are today
• Concept update
• Discussion
- Elevating vs. lowering freeway - Major cost implications
- Right-of-way and road alignment - Utility relocations
- Context-sensitive design - Other issues
• Phase 2 screening criteria
• Next steps
• Staying involved
VISIONGuiding solutions. Reflecting public/agency input.
Improve safety and
mobility for all users
on the Seward
Highway while
enhancing east-west
multi-modal, safety,
connectivity, and
access for Midtown
Anchorage.
PEL STUDIES IDENTIFY CONCEPTS/PROJECTS THAT:
Have Independent Utility
Are Fundable
Can Be Constructed in Logical Sequence
Have Minimized Impacts
FHWA PLANNING FACTORS
1. Support the economic vitality of the area.
2. Increase the safety of the transportation system for motorized and non-motorized users.
3. Increase the security of the transportation system for motorized and non-motorized
users.
4. Increase the accessibility and mobility of people and for freight.
5. Protect and enhance the environment, promote energy conservation, and improve the
quality of life.
6. Enhance the integration and connectivity of the transportation system, across and
between modes, for people and freight.
7. Promote efficient system management and operation.
8. Emphasize the preservation of the existing transportation system.
9. Improve resiliency and reliability of the transportation system and reduce or mitigate
stormwater impacts of surface transportation.
10.Enhance travel and tourism.

Agency Advisory Groups
One-on-One Meetings
Community Council Updates
PUBLIC/AGENCY INVOLVEMENT
WHAT WE’VE HEARD RECENTLY
• Dismiss the two-way frontage road concepts
• Resolve congestion issues at 36th Ave
• Resolutions from three Community Councils – advance depressed
highway concepts
• Consider greenways/covers over a depressed highway
• Active transportation connections remain important
• Give fair consideration of ROW acquisition from both sides of the
corridor
• Consider Fish Creek restoration
PEL STUDY STATUS
CONCEPT UPDATE
Intermediate Concept H
Concept C1 dismissed
Revised Concepts B and C2
New Concept J
HOW HAS CONCEPT B CHANGED?
• Shifted Tudor Road to the south at Tudor Rd interchange
• Added median u-turns at 36th Ave and connected the northern
u-turn with Old Seward Hwy
• Fireweed Ln ramping variation
• Mainline profile must go under 36th
• Road footprint is defined (eastern and western alignment)
• 50-foot wide utility easement to accommodate high voltage
transmission lines (east or west side)
HOW HAS CONCEPT C2 CHANGED?
• Mainline profile options:
• Over 36th Ave and under Benson Blvd
• Under 36th Ave and over Benson Blvd
• Frontage road extended on west side between Benson Blvd and
36th Ave
• Road footprint is defined (eastern and western alignment)
• 50-foot wide utility easement to accommodate high voltage
transmission lines (east or west side)
HOW HAS CONCEPT H CHANGED?
• Median U-turn -- Concept H-B
• Loop Ramp -- Concepts H-C2 and H-J
• Loop ramp and frontage road elevated over 36th Ave,
removing the southbound frontage road/36th Ave intersection
• Increases spacing between Old Seward Hwy/36th Ave
intersection and northbound frontage road/36th Ave
intersection

ENVIRONMENTAL CONSIDERATIONS
1. Historic Resources: Inventory and evaluation of structures in
areas of ROW acquisition will be necessary to determine adverse
impacts. No impact on a property on National Register of Historic
Places or known buried archaeological resources
2. ROW Acquisition: Varies depending on concept
3. Noise: Projects forwarded from the preferred concept(s) will
require a noise analysis as part of the NEPA process
4. Air quality: Projects forwarded from preferred concept(s) will
require evaluation in Regional TIP
ENVIRONMENTAL CONSIDERATIONS
5. Visual impacts: Dependent on whether preferred concept(s) is
elevated or depressed
6. Section 4(f) and 6(f) resources: All concepts impact Helen
Louise McDowell Sanctuary and Chester Creek Trail System
Degree of impact and mitigation to be determined
7. Environmental Justice populations: How concepts have
developed to avoid impacts on EJ populations
LAND USE CONSIDERATIONS
• Land Use Plan 2040 designations: City Center, Traditional
Neighborhood Design, Main Street Corridor, Greenway-
Supported Development Corridor, Commercial Corridor
• Some parcels have non-conforming rights (parking,
landscaping, drive aisles, etc.)
• Several parcels with parking/access issues, shared parking
with neighboring lots
• Some lots may require full acquisition as code required
minimum lot size cannot be met
• Strategy for resolving issues at each lot will be identified
PHASE 2 SCREENING
Themes:
1. Community Impacts
2. Connectivity and Access
3. Safety
4. Environmental
5. Non-Motorized Connections
6. Traffic Mobility/Operations
7. Implementation
8. Support
