It's hard to think of a "downtown" area for Richland, but if we were to have a central location, I think The Parkway serves as a decent choice. The Parkway is a street where a lot of local businesses call home, and we're lucky for it. It's pretty small, but this avenue serves as a nice little area to walk around and see some pretty cool and diverse shops.
The Ave is parallel to GW Way, and is just a few blocks from Howard Amon Park. On Fridays during the summer, The Parkway is home to arguably one of the best Farmer's Markets in the area (dare I say, even better than the Pasco Farmer's Market!). During the winter they have lights strewn around the trees along the street.
The Parkway is also fairly pedestrian friendly. Lee is just a one-way street, and there is a roundabout at Lee & The Parkway.
This isn't thorough, but as of this writing, here is a list of the businesses which are at The Parkway:
