Basic supply and demand. If demand (or appeal) of your neighborhood is lowered due to the appearance of the neighborhood then yes, over time values are negatively affected, simply because fewer people are attracted by said neighborhood. It's the main premise for most HOA rules, such as hiding the trash cans, no commercial vehicles, boats, campers, etc.
This is a classic example of why many HOA's and condo associations have a no marked or commercial vehicle parking rule in my area. I wouldn't say it's going to lower your property value, may just turn some people off. It also depends on the type of trucks, how often, etc etc
Indirectly. Potential buyers may not be interested in properties adjacent to this issue, sellers may reduce the price to leave this issue, and any sales might be at a lower value which will affect all overall property values in the area.
