Our town would like to scrap our sketchy PUD (planned unit development) chapter of the zoning ordinance until we have had time to come up with a better version, but meanwhile would like to have a set of rules to authorize clustering in subdivisions (previously only allowable in PUDs). Concerns include protection of natural topography and drainages, visual impact, density, etc. As the idea is to create something requiring little discretion so it can be used in the regular subdivision process rather than only in PUDs, it has to be pretty simple and clear. Any suggestions or examples? Thanks.
