Hi, Jennifer here from Code for the Carolinas! 
We would love to have folks from this forum–knowledgeable and passionate about Downtown Raleigh–join us in volunteering on this Open Sidewalks project! All are welcome and no specific technical skills are needed.
I wanted to share a bit more about what the end result of this project can be: a mapping and routefinding tool for pedestrians that also has settings for using a wheelchair or walker. Here’s an example of Seattle’s Access Map. This project is a partnership with the Taskar Center for Accessible Technology at the University of Washington.
We’ll be starting with an area centered on the Moore Square Transit Hub, because of its importance for public transit users, government buildings, and recreation.
I’ll keep an eye on this thread for questions and share a few updates on our progress!
