Zoning
PUD
Planned Unit Development District
Proper private development of infill areas, as well as the comprehensive development of large areas of vacant or substantially vacant land, requires a flexible approach to be available both to the city and to the landowner. The PUD Planned Unit Development is intended to encourage mixed-uses, allow a more flexible response to the market, and encourage innovative subdivision or site plan design that may not be explicitly accommodated by the standards contained within this code. Development within each PUD shall be clearly superior to development in a typical zoning district with respect to design, function, and compatibility with adjacent land uses.
