FAA Restrictions

What's the latest word from the FAA? Can anyone explain how the CBD is in the Boeing field flight path?

Well this is about 10 miles away. But incoming flights do pass over CBD.

Thanks, Tim very nice ... but as I understand it the FAA isn't concerned about SEA-TAC. It's Boeing Field they seem to fuss over and I can't see the problem. Can you perhaps find a similar chart for Boeing Field?

Yes sorry, I misunderstood your question.

This is for the Boeing Field Airport.



As you can see, most flight paths go just west past Downtown (1 mile) over Harbor Island and Elliott Bay.

I can't see any reason for the FAA to limit the building heights in the CBD because of Boeing Field. Thanks for the charts - they're very nice.

The only reason I can think of is there are some lone flight paths that do pass over CBD, maybe they think that a low flying plane in bad weather could hit it. Even with all the technology these days.

The team that wants to build the West Coast's tallest skyscraper in downtown Seattle is out with drawings that show more detail of the 101-story tower.

Miami-based Crescent Heights Inspirational Living and tower designer LMN Architects of Seattle looked at three possible shapes for the high-rise, including two options with rounded tops. But, as described in materials submitted to the city of Seattle, they would prefer to build a rectilinear tower whose vast mass is broken into "interlocking pieces."

The 3rd design is the cheapest and most efficient, but all three designs are nice.

Proposed 101-story Seattle skyscraper hits FAA snag

Quote:
The proposed Fourth and Columbia Tower...would be a mixed-use office and residential tower rising up 1,111 feet above the street. It would be 101 stories, with two levels of retail shopping, four levels of above-grade parking, and six levels of office space. It would also play home to 350 hotel rooms, and 1,200 residential units.

But the FAA has now sent the building's developer, Crescent Heights Inspirational Living, a "Notice of Presumed Hazard." The notice says "the structure as described exceeds obstruction standards and/or would have an adverse physical or electromagnetic interference effect upon navigable airspace or air navigation facilities."

The FAA says the 4/C is "presumed to be hazard to air navigation." But if Crescent Heights were to lower the building's height to roughly the height of the 965 foot Columbia Center, the project "would not have a significant adverse impact and a favorable determination could subsequently be issued," according to the FAA.

In a statement to KOMO News, Crescent Heights says the FAA notice is part of a "standard, business-as-usual review process" and "all development projects are presumed to be hazards until determined otherwise".

The consulting engineer hired by Crescent Heights, who is very familiar with working within rules established by Seattle and the FAA, says the notice of presumed hazard is just part of the negotiation process with the FAA when it comes to building heights.

"Most often these processes result in structure heights that meet developer needs while maintaining the integrity of our airspace system," said David Ketchum, Senior Planner Airports & Heliports for T-O Engineers.

Ketchum says he and the partners of the project have been involved in a lengthy review process that the FAA applies to almost all tall structures.

[...]

But being the tallest could be something [developer] Crescent Heights may not want to give up. — KOMO News

The FAA can go screw itself.

Hopefully it can still be agreed upon for this building to be a little higher than Columbia Center

This was a huge problem with MIA and the tall towers proposed in Miami but for some odd reason the FAA seems to be green lighting pretty much all of the tall towers.... I am sure it will work with Seattle on this as well. Keeping fingers and toes crossed for you guys!
