Blantyre LLC has proposed a residential community called Blantyre North and South on about 182 acres along Big Road and Colonial Road in Upper Frederick Township, Montgomery County. The plan calls for 278 homes. Of these, 58 would be detached single-family houses and 220 would be attached, stacked townhouses.
The plan also includes a new wastewater treatment plant, which the township would own and operate. It would replace the existing plant serving the Frederick Mennonite Community. The county's notes say a historic log home on the site is not addressed in the plans.
No developer page, news coverage, meeting minutes or permit records specific to this project were found online, so this summary relies on the county record alone.
What it could mean nearby
- A township-owned treatment plant would replace the existing Frederick Mennonite Community plant, which changes how sewage is handled locally.
- 278 new homes on Big Road and Colonial Road would add traffic and demand on local roads; no traffic study was found.
- The historic log home on the site is not addressed in the plans, so its future is unclear.
Where it stands
The latest county filing is dated January 28, 2025, which suggests the plan is still in local review. Usually the township planning commission and supervisors review a plan like this, and approval of the new sewage plant would also need state environmental review.
