The 33 new miles includes miles created by developers. I do not yet know the full story on this but I do understand that when a commercial developer develops a property - they are to put in a regulation sidewalk (5' wide, with a 4' green buffer). They are to create the sidewalk even if the remainder of the street is void of one. Even if no one walks there (yet).
The picture below shows a well done sidewalk in front of the Charlotte Av Police Department - The West Precinct. Psychologically, when walking right here - it has a great feel. You are physically buffered from the cars by the patch of grass and trees.
Let your eye follow the sidewalk to its terminus where it empties into a parking lot of a tire repair shop. You can see the difference. This shows the importance of high quality well designed sidewalks here in Nashville. They make a significant difference.
Still waiting to hear how many miles of new sidewalk were produced by Public Works last year. As soon as I know, I will write about it.
That being said - I'll take any well designed high quality sidewalk in Nashville no matter who makes it. These bits and pieces created by developers & individuals (yes, you can DIY if you choose) add up over time. In addition, Public Works has states that these 'sidewalks to nowhere' actually hold heavy weight when a road is evaluated for a sidewalk.
