THIS IS ALL CONJECTURE SO FAR
But if you take a moment to think about it, which elementary schools do you suppose would be in the assignment area for Eckstein? Since there is no middle school further north or east of Eckstein, then any elementary school attendance area north and east of Eckstein will likely be in the Eckstein area. In fact, when planning this, you might start in the northeast corner of the district and work out from there in an expanding radius until... until Eckstein is full.
That would make the Eckstein feeder schools to be John Rogers, Olympic Hills, Sacajawea, and Wedgwood with high confidence. Then I reckon would come View Ridge, Northgate and Olympic View. After those six, would there be room for any more?
By this reasoning, Whitman's feeder schools would be Greenwood, North Beach, Loyal Heights, Whittier, Adams, and maybe Bagley. That's six. It doesn't seem that Whitman would have room for Northgate and Olympic View.
That would mean that the feeder schools for Hamilton would be West Woodland, Greenlake, B F Day, JSIS, Bryant and Laurelhurst. That is also six.
If Laurelhurst and/or Bryant were added to the Eckstein region, then Northgate and Olympic View would have to rotate out to Whitman which would bump Bagley at least to Hamilton, but what other school? I'm not seeing it. Also, those Northeast schools are big. There are only so many that Eckstein can take. I'd be interested in hearing other projections.
The feeder schools for McClure would, rather obviously, be Lawton, Coe and Hay, plus Old Hay when it comes back online. Queen Anne/Magnolia students at B F Day would have a cohort tie-breaker to go to Hamilton.
The Washington feeder schools would be Montlake, McGilvra, Stevens, Lowell, Gatzert, Leschi, and T. Marshall - seven.
Mercer's feeders would be Beacon Hill (which is why Mercer would have to become an international middle school), Muir, Kimball, Hawthorne, Maple, and maybe Dearborn Park. That would be six.
Aki Kurose's feeders would be Graham Hill, Brighton, Wing Luke, Van Asselt, Dunlap, and Emerson - six.
Madison's feeder elementaries would be Alki, Lafayette, and Schmitz Park for sure, plus some share of Gatewood, West Seattle, and Sanislo.
Denny's feeder elementaries would be Arbor Heights, Concord, Highland Park, and Roxhill for sure, plus some share of Gatewood, West Seattle, and Sanislo.
The biggest question in my mind is the division of the West Seattle middle school reference areas. The rest is pretty clear to me.
Doesn't that make sense?
