Correction: An earlier version of this story incorrectly reported that the new Costco store was being built at FM 529 and the Grand Parkway (SH 99). The store is actually being built north of FM 529 at West Road. We regret the error.
NORTH WEST HARRIS COUNTY (Covering Katy News) – Residents of Elyson, Marvida and northern Katy will soon have a much shorter drive to Costco.
Costco Wholesale Corp. has filed plans to build a new warehouse and fuel center at the southeast corner of the Grand Parkway (SH 99) and West Road, giving many shoppers a closer option than the retailer's location near Interstate 10 and the Grand Parkway.
For many families living north of Interstate 10, a Costco shopping trip often means navigating traffic to the Katy location, which can become especially busy on weekends. A new store near Elyson will offer a more convenient alternative and could ease some of the demand at the Katy warehouse.
According to filings with the Texas Department of Licensing and Regulation, the project includes a 160,000-square-foot warehouse and an 11,680-square-foot fuel center with a combined estimated construction cost of approximately $68 million.
The warehouse is estimated to cost about $65 million and the fuel center will cost about $3 million.
According to the filing, the project consists of a "new construction pre-engineered metal building with metal panel and masonry exterior." It will be about 160,000 square feet.
The new store will be located in northwest Harris County at the southeast corner of SH 99 and West Road, an area that has seen explosive residential growth over the past several years. Thousands of new homes have been built nearby, creating demand for additional shopping, restaurants and other services.

The Costco construction sign can be seen in the background near the West Road exit of the Grand Parkway northbound.
Although Costco has not announced what features the new store will include, warehouses of this size typically offer groceries, fresh meat and produce, a bakery, pharmacy, optical center, tire center and a fuel station.
Construction is scheduled to begin March 1, 2026, according to the TDLR filing, with substantial completion expected by Nov. 6, 2026. Costco has not announced an opening date, but if construction remains on schedule, shoppers could begin seeing activity at the site early next year as crews prepare the property and begin building the warehouse.
The project is another sign of the continued growth along the Grand Parkway corridor, where major residential developments have attracted new retailers, restaurants and commercial investment.
Costco warehouses typically employ several hundred workers, including both full-time and part-time employees, although the company has not announced staffing plans for the new location.
