Chestnuthill Township is updating its official map.

Supervisors held a public hearing Tuesday night for the update, which is being done, in part, to reflect new road names generated by Monroe County's 2010 readdressing project.Other changes from the township map, last updated in 2010, include lands that were identified as a "consideration" and have since been "acquired" that have been updated to reflect the change. An example would be 52 acres of land owned by the township off of Little Mexico Road.The majority of additional properties that were updated are located from the intersection of routes 209 and 115 to their intersections with Weir Lake Road. These properties are now identified as "Road and Intersection Improvements," specifically for widening by PennDOT.John Nash, who has a real estate office along Route 209, said he was concerned about a septic system in the front of the property if the width of the right of way changed.In October 2014, supervisors held a public meeting and invited all the property owners who were added to the 2015 map."The state is talking about these widening projects coming at some point and we wanted to show the affected properties as a heads-up to property owners," said Supervisor Chairman Carl Gould. "We didn't want to see anyone investing needlessly on something that wouldn't last. If we hear something from PennDOT, we will take the initiative to notify affected property owners."The new map is available on the township's website, www.chestnuthilltwp-pa.gov.In conjunction with the Monroe County readdressing project, township employee John Mathews updated each address, over 10,000 total, within Google Maps so people searching for a business or residence in Chestnuthill are taken to the correct location."Previously, businesses couldn't be found online and residential addresses were not navigable," Mathews said. "For example, if you searched for the Monroe County Control Center, you would be taken to the wrong location."Chris Eckert, supervisor vice chairman, said when the county finished the readdressing project, the contractor promised to update all of the GPS information within six months, but that didn't happen."It's been over two years now since the completion, and we felt this was important, especially for our businesses, so that they could be found accurately within Google Maps," Eckert said. "To my knowledge, we are the first municipality in the county to do this."
