SOPI - Natural Lands Oakwell
CLAIREMONT RD, Lower Merion, PA · 1,200 sq ft non-residential, lot line change · 52.0 acres
About this project
Natural Lands Trust is planning to expand its Stoneleigh garden by buying 13.1 acres from the school district, with the change handled through a lot line change and tentative sketch plan. A roughly 3-acre parcel holding the Oakwell mansion would be split off and owned by the Wyncote Foundation, which plans to restore the mansion under a conservation easement. The plan also includes about 50 new parking spaces tied into existing lots, along with a welcome center.
Issues raised: turning radii where new parking meets existing lot, pavement markings and stop signs at parking connection, fire truck access and maneuverability, looped parking area near welcome center, sidewalk on Montgomery Avenue deferred, emergency dispatch site access and addressing
