Sabin open: some of Irvington into Sabin

Irvington closes, and its area is split along two collector streets, NE 15th Ave and NE Knott St, not through the middle of the neighborhood. North and west of the line go to Sabin; south and east go to Beverly Cleary. Every Sabin-area family keeps its school.

• The accessible building stays open. Sabin has an elevator to all three floors (state register; final inspection 1995) and a registered stage lift. Irvington has no elevator or lift on record. PPS’s own 2008 deficiency list says “Elevator Is Missing And Needed”, and its 2009 accessibility study says Irvington’s media center and cafeteria “are located in inaccessible levels”.

• Geography points this way, not the reverse. Irvington’s families split almost evenly: about 114 kids live closer to Sabin and about 109 closer to Beverly Cleary. Sabin’s families are surrounded by closer schools (King, Alameda, Vernon): only 25 of Sabin’s 236 live closer to Irvington, and in the model runs a Sabin-into-Irvington merge leaves Irvington at about 224, far under 360.

• Sabin stays whole. Every Sabin-area family keeps its school, including about 67 kids experiencing poverty (28%, the higher share of the two areas). The Irvington-area kids who move include about 47 experiencing poverty.

• Kids follow their elementary school. The Sabin side goes on to Tubman; the Beverly Cleary side goes to Beaumont, then Grant. No elementary school is split between two middle schools. In this version, Irvington-area teens stay at Grant, as today.
• More kids can walk. In the Sabin and Irvington areas, about 204 more kids live within the state’s no-bus distance of their school than under PPS A or B (1 mile K-5, 1.5 miles middle and high school): K-5 386 vs 225, middle school 85 vs 42, high school 311 vs 311. Scenario D adds about 108.

• Ready for 2027, with no construction. It also works with Scenario D’s plan to use the Irvington building as the swing site while Beverly Cleary is retrofitted.

• Every Irvington family changes schools, and their average walk grows by about 0.35 mi (0.54 to 0.89 mi).
• Sabin and Beverly Cleary both land just under 360.
• District-wide, closing both Sabin and Irvington scores slightly better on PPS’s measures: about 300 fewer kids sent past a closer school, and fewer kids over the bus line.
• It leaves Vernon at about 288 and Tubman on N Flint, next to I-5. That’s why moving Tubman into Vernon is the better plan; this one is the fallback if PPS won’t move Tubman.
