HBK 2022/23 build plan — cross-referenced to FCC fiber (Jan 26)

Original 80-zone HBK build plan re-evaluated against the latest FCC fiber-deployment data. 34 zones still open (12,347 non-fiber BSLs); 26 partial; 20 saturated and effectively closed by incumbents.

Open (<50% fiber, 34 zones · 12,347 non-fiber BSLs) · Partial (50-90%, 26 zones · 6,584) · Saturated (≥90%, 20 zones · 488)

Revised build zones — tight polygons around non-fiber BSLs

DBSCAN-clustered the 102,279 non-fiber BSLs in Tarrant (FCC Jan 26) into 178 tight zones covering 81,449 BSLs. 41 large (≥500 BSLs · 54K total), 45 medium (200-500 · 15K), 92 small (80-200 · 12K). 29 zones are mostly or entirely outside the HBK 2022/23 plan footprint.

Low-cost build zones — alley-rich + aerial-eligible

Subset scored for rear-lot aerial: alley density (drops off both sides of pole), BSL density, and HBK aerial-fiber proximity where known. 29 zones · 9,325 non-fiber BSLs. 6 tier-2 (highest signal), 23 tier-3. Built from 167 mi of OSM-tagged Tarrant alleys + the HBK Phase 1 aerial/UG distribution table.

DA Phase 1 — capital ask (7 AOIs)

Subset of the 14-zone plan being financed in this round. Tier-colored by Plant CPP (VCTI BOM v1, Jun 24) against Will's $1,100 green-line framework. Tier A immediate: 3,023 pass · $3.48M · $1,151 CPP. Tier B (gated on 50% pre-signups): 1,176 pass · $2.22M.
