The community of Stebbins is accessible by air and water, but is most dependent on air travel. Therefore, it is vital that this airport continues to safely serve the public. The existing airport facility consists of a 3,000-foot by 60-foot gravel runway, with a 250-ft by 120-ft runway safety area (RSA). The apron is 160-ft by 375-feet and is located 225-ft from the runway centerline (Refer to Figure 2). The taxiway is 25-ft wide by 225-ft long, with a safety area width of 50-ft. Navigational aids consist of rotating beacon, pilot activated medium intensity runway lights, a segmented circle, and a windsock.
This project will address the following deficiencies at the Stebbins Airport:
 |
The existing gravel runway does not meet the required dimensions of 4,000-feet by 75-feet to serve the current and projected fleet of aircraft operating in the region and to accommodate instrument approaches. |
|
The existing RSA does not meet the current standards of 150-ft width and 300-ft length beyond each runway end. |
|
The apron is also inadequate for airplane ground operations. The apron is located 225-feet from the runway centerline. As a result, airplanes on the apron penetrate the Part 77 transitional surfaces. |
|
The taxiway width of 25-feet and safety area width of 50-ft are inadequate. Current standards are 50-ft width by 120-ft safety area standard. |
|
Land is inadequate to support the airport. There is no room for aviation support area and the required runway protection zones. |
The proposed project would relocate the taxiway and apron, extend the runway to 4,000-feet, and construct an airport access road. These improvements will require additional property. The table below summarizes other actions associated with the proposed project. Airport Design Dimensions (Existing and Proposed)

In September 2004, DOWL Engineers conducted a study that included classification and mapping of wetlands using aerial photography, a field survey to verify wetland and upland boundaries, functional assessments of each wetland type, mapping of vegetation and habitats, and an evaluation of habitat values for selected wildlife species. This data will be used to assess impacts to wetlands and other wildlife habitat. The report will be available early spring 2005.
