Lower Merion Township has partnered with Parkmobile, LLC to soon allow Township residents and visitors to use their mobile devices to pay for metered parking. Starting the week of April 23rd, Parkmobile will be added to meters throughout the Township. Keep your eyes out for the Parkmobile green decals on the meters and use your app to pay for parking.
