A developer plans to build 12 townhomes on about half an acre at 151 East Mount Vernon Street in Lansdale. The homes would replace two duplexes now on the site. The site already has public water and sewer.
The Montgomery County planning commission generally supports the plan. It asked for three changes. The first is a clearer definition of how the stacked units are counted and arranged. The second is a shared outdoor space for residents. The third is a decision on what will happen to an adjacent alley.
No news coverage, developer project page, or borough agenda or minutes specific to this project turned up online. Whether anyone opposes it, and who the homes are meant for, is not publicly known from the sources found.
What it could mean nearby
- Homes would rise from the 4 existing duplex units to 12 townhomes, which adds housing close to the center of Lansdale.
- The adjacent alley's future use is still undecided, so access and traffic patterns on the block could change depending on that decision.
- A shared outdoor space is requested, which would add some open space for residents.
- Public water and sewer are already on the site, so major new utility extensions are not expected.
Where it stands
The county planning commission reviewed the plan in its latest filing (August 2024) and is generally supportive, with requested changes. The next step is usually review by the Lansdale Borough Planning Commission and Borough Council, which then consider land development approval. No later action was found online.
