Two additional Reimbursable Agreements were required for Construction
Required Coordination with various levels of the FAA
Environmental Assessment
Full EA required due to the presence of wetlands
Coordinated with Resource Agencies
Completed Alternatives Analysis
Reviewed Environmental Impact Categories
Reviewed Environmental Consequences

7. Additional Items to Consider
Geotechnical Investigation
Borrow Area
Determined how much material was available
Developed new Blasting Plan
Developed haul route to work area(s)
Fill Placement
Needed fill benching plan
Develop tie-in with existing steep fill slopes
Complete slope stability analysis for various fill slopes
Analyze potential for mine void issues
Large Boulders
Left over from previous fill projects
Needed to be incorporated into fill placement
Determine how to break them down to useable sizes
Determined how to haul them to the work area(s)

8. New FAA Taxiway Design Criteria
New Advisory Circular design criteria was used
An Aircraft Analysis was completed
The wingspan of the Aircraft using the Airport met FAA Airplane Design Group III
118’ Taxiway Safety Area
186’ Taxiway Object Free Area
Based on the MD-Series Aircraft, the new TDG was 5 for this project
Taxiway Design Group 5 Criteria
75’ Taxiway Pavement Width
25’ Taxiway Shoulders
12.5’ Paved Shoulders (each side)
12.5’ Turf Shoulders (each side)

9. Alternatives Five (5) final alternatives were analyzed
Straight taxiway extension with a capture-effect GS antenna on the right side of the Approach
Taxiway extension that was routed around the GS critical area with a capture-effect GS antenna on the right side of the Approach
Straight taxiway extension with an end-fire GS antenna on the right side of the Approach
Straight taxiway extension with a capture-effect GS antenna on the left side of the Approach
Straight taxiway extension with an end-fire GS antenna on the left side of the Approach

11. Preferred Alternative (#4)
Extend Taxiway B to Runway 22 End meeting current FAA Design Criteria
75’ Taxiway Width and 25’ Shoulders (12.5’ Paved/12.5’ Turf)
Relocate Runway 22 Glide Slope Antenna to left side of Approach
Capture-Effect Antenna
Place fill to create required Glide Slope Critical Area
Most expensive and most environmentally sensitive option
Higher cost due to need to fill GS critical area
Required land acquisition for GS critical area fill
Impacted 0.27-acre of wetland area
Could be constructed with limited impact to Airport operations

12. Preferred Alternative (#4)
