Granbury ISD demographic study projects modest near-term student growth, flags 30 active subdivisions and conservative yields

Granbury Independent School District trustees on Monday heard a detailed demographic and housing analysis from Zonda Education that projects modest near-term student growth driven by expanding housing stock but lower-than-historic student yields per home.

The presentation, led by a Zonda demographer, said “you have approximately about 64,000 residents within the district,” and noted about 26,000 households, an average household size of 2.43, and a median age of roughly 48. The consultant told the board Zonda identified 30 active building subdivisions in the district with about 1,600 lots ready to build and more than 8,000 conceptual “future” lots that could come online over years of phased development.

Why it matters: Granbury ISD trustees use enrollment forecasts to plan staffing, facilities and the budget. Zonda’s presentation led the board to adopt conservative assumptions for next year’s budget, and trustees discussed timing and model changes as the district weighs whether and when to add classrooms or a new campus.

Zonda presented several development-specific details and projected student yields — the number of students expected to live in each new home. Examples called out in the presentation include Brookside (listed as about 876 total lots, with an early phase of roughly 50 vacant developed lots and an LGI Homes presence) and Crescent Estates (approximately 304 total lots with about 92 vacant developed lots and about 14 students currently geocoded to that subdivision; Zonda referenced a yield near 0.298, meaning roughly three students per 10 homes). The consultant also named Abe’s Landing, Legacy Ranch, Cardinal Woods and several smaller projects as active or future subdivisions in the…
