Northside and Diamond Hill out to Heritage and Lake Country

The north side of the river grew around cattle. The first long drive of longhorns from South Texas to the Kansas railheads came through Fort Worth in 1867, and the drives kept coming until the early 1880s, by which time the city was shipping cattle north by rail. The Union Stock Yards, chartered in 1887, opened north of the Trinity in 1889, and the Armour and Swift packing plants that opened beside them in 1903 drew Mexican and Eastern European workers to the neighborhoods north of the river, which the Handbook of Texas calls still the most ethnically diverse part of the city in the early twenty-first century. Fort Worth annexed North Fort Worth in 1909 but left the stockyards and the plants outside as a tax-free industrial district, and when it planned to take them in, the stockyard interests incorporated Niles City, which lasted until 1922, the year the city annexed it with Diamond Hill and Rosen Heights. The last auction was held in December 1992, and the Stockyards, on the National Register since 1976, are now mostly shops, restaurants and weekend rodeos. Out beyond Loop 820, Fort Worth Alliance Airport, built by the City, the Federal Aviation Administration and Ross Perot Jr.'s Hillwood Development as an industrial airport, opened on 14 December 1989, and Eagle Mountain Lake, finished on the West Fork in 1932, lies just upstream of Lake Country. 4 guides are listed below.

The school district changes up here. Northside and Diamond Hill are Fort Worth ISD, the district the arithmetic on this site's calculators is built on, at 1.0291 per $100 for 2025, but Heritage is Keller ISD, at 1.0852, and Lake Country is Eagle Mountain-Saginaw ISD, at 1.2457, so those two guides work their bill out from the units the appraisal district lists for the property rather than from the example here. Heritage also sits inside the City's Heritage public improvement district, established in 2000, whose assessment on a house was 0.145 per $100 in 2025, and a few blocks of Northside are in the Stockyards district, at 0.12. And the edge of the city is close on this side: Saginaw, Blue Mound, Haltom City, Watauga and Keller are separate cities to the north and northeast, so an address out here is worth checking against the City's limits before anything else.
