I'm developing a new zoning ordinance for a small lakefront community that is proving remarkably progressive on parking requirements. Some committee members actually suggested that off-street parking for locations "in the grid' -- in the older part of the city -- could be reduced based on the availability of on-street parking. Seems like a great idea, but I don't think I've ever seen an example of it.
Of course, many cities, like this one, don't require off-street parking in their downtowns, but this would apply to other nonresidential and mixed use districts. Can anyone provide any examples or suggestions?
