I guess that's better than surface parking.Hopefully it can be done somewhat attractively. Office space on the ground floor is better than parking on the ground floor to. Seems weird they'd only need a single floor but I'm sure we'll learn more soon.....County is spending a fortune on this.
Yes to everything you've pointed out.
The site is one of the higher profile gateways into Downtown; there should be consideration to building something both interesting and productive. On the ground floor, maybe a grocers to meet the demands of the nearby neighborhood; on levels 2-3 perhaps administrative space; and 4-8, parking for court business and employees. Without specifics, its impossible to know what is planned, but it would be good if the county put a lit thought into the project.
