Hypsometric
Mapillary from 2018 and Bing Streetside from 2021 shows it as Avenue. Some properties on 287th Place are listed with the address Place while others have Street. Maybe things have changed here or the county was not recording these correctly. I've seen that in my local county which is far from here. It doesn't seem that uncommon. Any chance we can get a photo of the street sign from the current date? If you are from the area, that is.
