Thank you for asking. I chose living street because I was on the fence between that or pedestrian street. Maybe Pedestrian street would be more appropriate and I can agree with that. For alley way, as per the description: "An alley is a service road usually located between properties for access to utilities.".  Since these smaller streets do go directly to residences, hanouts, riads, etc, I didn't feel like these were appropriate. I'm definitely open to discussion on this and am willing to go back and adjust some of these smaller streets to pedestrian streets.
