There doesn't seem to be a trail but only a parking lot from 2023 satellite and 2022 google street view. The city's 2022 bike map [1] also didn't include this section as a cycle trail. 
Only the "Treeline Conservancy" marked [2] this section as "in operation" on their website without detailed alignment.

Need survey.
