Does any have any ideas on how to provide a project administrator an option to view available capacity for the project they are managing besides creating a dashboard in vRops?
Ideally, this would be a simple section within vRA Service Broker.
If vRA is integrated with vRops, then you can possibly create a dashboard for the users, but this means that they will need to navigate to vRops to view that. (Within vRops, you can navigate to Environment, Cloud Zones, Project select the specific project and select the appropriate metrics like "CloudZone Limits" to create a dashboard).
Within VMware Aria Automation/vRA it is not possible , as you said vrops allows this as out of box
