Clemens Mill is a proposed small neighborhood on about 2.14 acres along Main Street in Lower Salford Township. County records describe 12 new twin homes, which are two attached homes on one building. Two existing homes would stay, so the site would have 14 homes in total. Six homes would face Main Street. Eight would face a new street called Chelsea Lane.
The site is in the township's Village Commercial zoning district. It would connect to public water and sewer. Plans also include new sidewalks, a public walking path and stormwater facilities to manage runoff.
The township's "Eye on Development" page lists the project as 12 twin homes. It appears both as approved at the preliminary plan stage and as a final plan under review by the supervisors. Township planning commission agendas from 2023 and 2025 show the plans have been reviewed over several years. No news coverage, opposition or named occupants were found.
