Airport Master Plan 2012 - City of Waterville

Although much less frequent, a number of other large corporate aircraft nonetheless use WVL including
the Bombardier Global Express (ARC C-III), the Gulfstream G-IV (ARC D-II) and the Gulfstream G-V
(ARC D-III), but their current and forecast operations do not justify changes in the ARC.
Design Standards
The forecasts, inventory assessment and review of current design standards will determine the runway
and taxiway improvements needed. FAA Advisory Circular 150/5300-13 entitled, Airport Design, sets
forth recommended runway and taxiway design standards for all reference code airports. The design
standards for the current and future airport facilities are set forth in Table 3.2. Included in this table are
the existing conditions and future runway dimensions for the design aircraft. Also included are the
existing conditions and the dimensions required for the recommended forecast scenario.

Runway edge and threshold lighting consists of high intensity lighting (HIRLs) on Runway 5-23 and
medium intensity lighting (MIRLs) on Runway 14-32. HIRLs are consistent with FAA standards for
precision instrument runways like Runway 5-23. The lighting systems have been well maintained over
the years and are generally reliable but need replacement due to age and continued deterioration. Portions
of the Runway 5-23 lighting system were last replaced in 1984 and in 1987 when the runway was
extended. In-pavement light foundations have become corroded and have settled into the asphalt and
need replacement. The lighting system serving Runway 14-32 is in excess of 25 years old.
The present taxiway configuration at WVL is generally adequate to serve the present level of aircraft
operational activity. All existing taxiways currently meet or exceed required dimensional standards for
the projected planning period.
