Planned Arterials?

I was looking at the street classification map on-line at seattle.gov and noticed something I hadn't noticed before. It is something called Planned Arterials. Maybe I missed it previously or maybe it's new. Anyway, there's a few of those planned in the south sector, and north sectors of the Greater Greenwood Bi/Ped Safety Coalition area.

I'd like to know more about it.

It worries me when residential streets become defacto arterials. I don't know how this particular thing works. Planned Arterials. I would not want my street to be reclassified as an arterial.

I think we already dedicate more than enough of our right of ways to vehicles.

Take a look at this map. Look at the legend for planned arterials.

There's one over Phinney Ridge and down to Market St. Another couple in Blue Ridge (14th) / near Carkeek (105th) and some up in Broadview as extensions of streets west and Linden Ave. Dale Johnson from the Broadview CC said that by taking the arterial classification on Linden, it puts them in line for street improvements, but does it really? Look what's happening on Greenwood N? Is that an improvement? Are there any guarantees that Linden wouldn't eventually become a formalized bypass for Aurora?

Seems risky.
