I just came from a meeting I had requested with the airport manager, newly appointed. The teardown of the hangars is definitely on the agenda, but they would intend to pay us for our hangars and provide some new hangar facilities so we would not leave the area.
At one time I was spending 20 hours a week on airport affairs...call it temporary insanity. I did learn a few things, and 08A is still on the map.
Best I know, every airport sponsor is required to name a consulting engineering firm in order to qualify for Federal money. Silly pilots may see them as being on the enemy team, but the reality is you want to make them your best friends.
They're every bit as interested in planning and project management as they are in actual engineering design; it generally pays a percentage of the project value. In the case of real or personal property acquisition involving Fed money, they also get paid for handling the required multiple appraisals, negotiations, surveys, etc. So, it is much better for them to recommend a buyout and rebuild (which they will cheerfully handle), as compared to condemning and throwing you out (the city attorney's job). This particularly true since it became allowable to use AIP money to build new hangar space about 12 years ago.
Short term goal? Make friends quick, because they recommend what the airport sponsor should do. They also help decide how much you get paid for what you have, and recommend, design, and build what you get in the future.
Your long term goal is to guide them toward airport projects you want, projects that also make money for them. They will sway the sponsors for you
when it is in their interest. Be careful around that two-edged sword.
I don't know the current Fed requirement, but 15 years ago the building restriction line for a new runway at our airport was 500 ft from the centerline. A glance at an overhead of T65 says yes, your old hangars are a problem.
