There's no specific parking lot or parking garage to validate the parking. There are parking garages nearby on Union Street or street parking.
Best bet is to Uber/Lyft.
No separate parking facility. There is on-street parking (paid) in the area, and 1 or 2 garages within a few blocks. See: https://is.gd/q9L3va BTW, good food and delightful outdoor seating along the dock!
