Is there a plan to restrict the number of non-members parking at the club? My understanding of the current hall rental contract is that hall guests are allowed to park on the civic club grounds and are only limited based on the number of parking spaces available. This isn't a problem during winter months, but becomes an issue during the summer.
If there is not a current plan to limit hall guest parking on the club grounds, I would suggest that there be a designated area with 3 or 4 parking stalls that are posted as "Hall Rental", or "Visitor" parking spaces. All other hall guests can park across the street by City Hall.
