Got it. Thanks for feedback!

I understand your reasoning. I will do more research. Thanks.

I'm questioning my change from 'residential' to 'tertiary'. I downloaded GeoBase 'NRN_BC_14_0_ROADSEG' dataset and it says 'Local / Street' which I'm assuming is 'residential' but it feels like 'unclassified' or 'tertiary' to me. I would like to discuss this further if anybody is interested.

Way 834816257 is 4m wide mixed use path. More info here: https://www.portmoody.ca/en/city-services/resources/Documents/2019-Murray-Street-Upgrades-Project---Maps.pdf
Regarding multi-use (mixed use) path tagging, I thought a lot about it. `highway=cycleway` or `highway=footway` tags seem like they prioritize one group over the other and I didn't feel comfortable with that. After thinking for while I decided to follow recommendations outlined here: osm.wiki/Tag:highway%3Dpath and here: https://github.com/BikeOttawa/OSM-Bike-Ottawa-Tagging-Guide. They recommend using highway=path. Also, I use BikeOttawa algorithm to create Traffic Stress (LTS) cycling map for Tri-Cities so I prefer to use their recommendations.

Hi keithonearth,
Regarding Way: 834816257. City of Port Moody recently upgrades this sidewalk to multi-use path (completed May 2020). Do you mind if I remove your changes for this way?
