Apron Alternatives Analysis
Analysis Factor
Impact
T0: No Build (Status Quo)
Engineering Not Applicable
Operational No improvement to Airport efficiency.
Environmental None – no change.
Land Use None – no change.
A1: Construct Phase II of the current Terminal Apron Area
Engineering Already designed, expensive construction cost (for large AC)
Operational
Significant benefit- Satisfies the Facility Requirements through 2017
Adjacent to Existing Terminal/FBO operations.
Environmental Limited – increases impervious surface.
Land Use None – no change.
A2: Rehabilitate the former Telford Apron
Engineering Requires design, less expensive than new construction
Operational
Satisfies Facility requirements through 2017 but far from Existing Terminal/FBO
operations.
Environmental No Change
Land Use No Change
A3: Expand current Terminal Apron to accommodate Based Aircraft
Engineering Requires design, more expensive than rehabilitation
Operational Limited – Satisfies tie-down requirements through 2017
Environmental Limited – Increases impervious surface
Land Use No Change
A4: Expand and Use the Approach End of Runway 14 for Apron Construction.
Engineering
Requires design for Taxiway, Apron and access road design; significant
construction costs required by all three components.
Operational
Significant operational benefits for Corporate Flight Department or New FBO
development
Environmental Limited – impervious surface likely to be offset by Runway 14-32 removal.
Land Use None – No change
Apron Alternatives Conclusion
Of the four original alternatives, the City chose to proceed with Alternative A-1. However it should be
noted that state funding guidelines require a new “design” for this area since the existing design has far
exceeded the 2-year “shelf life” allowed by the State of Maine. Alternative A-2 was eliminated due to the
combination of development constraints of the Airport property boundary and limitations associated with
Runway 5-23 airspace. Alternatives A-3 and A-4 were eliminated as a result of keeping Runway 14-32
open.
In addition to Alternative A-1, the City also expressed an interest in developing the so-called Area “G”,
which is located due north of the intersection of Runway 14 and Taxiway A. This area was previously
considered for future corporate development and provides reasonably good potential for future apron
space. Therefore the City has decided to proceed with future apron development identified by Alternative
A-1 as well in Area G.
