As early as this month, preliminary site plans for a new development at Don Guanella could be released. Still owned by the Archdiocese of Philadelphia, the massive 213-acre site that borders Sproul Road and Reed Road has been a target for development for some time.

A coalition of local homeowners and community activists called “Save Marple Green Space” have aimed to protect the mostly open space from development since initial plans came to the public forefront by Goodman Properties’ plan to build one million square feet of business and retail space, along with 250 residential units and amenities.

After that plan was denied, the large site remained out of the news until recently. In December of 2017, Conshohocken-based Carlino Commercial has entered into an agreement with the Archdiocese for the site. Their proposal hopes to address many of the unpopular issues from the first developer’s vision, including maintaining an open space of 175 acres.

Even still, members of Save Marple Green Space cite environmental and traffic concerns as big drawbacks for any development of the area. Many residents remain hopeful that Carlino’s vision will take into consideration the initial opposition.

Plans will be posted to Marple’s website at
