Costco Wholesale proposes to enlarge its existing warehouse store at 740 Upper State Road in Montgomery Township, Montgomery County. The store, known as the Montgomeryville warehouse, sits on a site of about 16 acres.
County records describe about 17,400 square feet of new building space, added through three separate extensions to the current building. One extension would hold truck loading and unloading. The parking lot and drainage areas would change only slightly.
No news coverage, township agendas or minutes, or approval decisions specific to this expansion were found online. Costco's own store page lists the warehouse as open since 1999 but says nothing about the expansion. The details here come from the county records alone.
What it could mean nearby
- The records say the parking lot would change only slightly, so large changes to site access or parking are not indicated.
- One extension is for truck loading and unloading. Any effect on delivery traffic or noise has not been described in the sources found.
- Drainage areas would see minor changes, so stormwater handling would likely stay much as it is now.
Where it stands
The latest county filing is dated 2025-10-15, which suggests the plan is in township and county review. No approval or decision was found online. Next steps usually include township staff and engineer review, a planning commission discussion, and a vote by the elected township body.
