Community Overview
Katy's lakefront answer to the classic suburb.
Grand Lakes opened in the late 1990s along what became the Grand Parkway corridor, and its defining feature is water. Neighborhoods of single-family homes step down toward stocked lakes, and the community's parks, ponds and trail loops make it one of the greener options in central Katy's 77450 ZIP, with a newer Phase 4 section across in 77494.
The housing spans the full curve of the market: first homes, trade-up single-family stock and waterfront properties at the top end. Katy ISD schools, easy Grand Parkway and I-10 access, and that water-centric amenity layout keep Grand Lakes one of Katy's most consistent performers for resale value.
