TABLE 4.3. DESIGN CRITERIA FOR RURAL AND RESIDENTIAL
ZONING DISTRICTS

A = applicable; N/A = not applicable

Design Criterion	CONS	AG	RR	R-30	R-20	R-15	R-7.5	R-TH
Compatibility. New development and improvements to existing properties need to be compatible with the existing character.	A	A	A	A	A	A	A	A
Floodways and floodplains. Prohibit development within floodways and restrict or prohibit development in floodplains.	A	A	A	A	A	A	A	A
Access to abutting public conservation lands. Subdivisions are strongly encouraged, if not required, to provide pedestrian easements or fee simple land dedications to public open spaces (including greenways) or publicly designated conservation lands on all abutting properties.	A	A	A	A	A	A	A	A
Curb and gutter. New roads or road improvements should not include curb and gutter unless demonstrated need exists.	A	A	A	A	A	A	A	A
Road and lot layout. New subdivisions must observe existing traditional neighborhood development principles, including a grid pattern of connecting roads, rectangular-shaped lots, and block widths and lengths that do not exceed 600 feet.	N/A	N/A	A	A	A	A	A	A
Cul-de-sacs. Circular turnarounds shall not be permitted except in the most unusual circumstances when demonstrated needs exist.	N/A	N/A	N/A	A	A	A	A	A
Parking. Off-street parking between the front facade of the principal dwelling and the City street is strongly discouraged and instead design should facilitate rear or side yard parking.	N/A	N/A	N/A	A	A	A	A	A
Alley access to parking. Alleys or driveways accessing the rear of the dwellings are encouraged in order to provide parking access from the rear lot line rather than the front of the dwelling.	N/A	N/A	N/A	A	A	A	A	A
Parking garages for individual units. Garages should be located to the rear or side of the dwellings they serve, but if they must be located in the front of the dwelling, garages must be recessed back at least five feet behind the front wall of the dwelling so that it is subordinate rather than dominant when viewed from the City street on which the dwelling fronts.	N/A	N/A	A	A	A	A	A	A
Land consumption. New development, if permitted, should be designed to minimize the amount of land consumed; open space must remain to some extent.	A	A	A	A	A	A	A	A
Open space design. Promote and pursue principles of landscape ecology when reviewing large developments and major subdivisions.	A	A	A	A	A	A	A	A
Agricultural outbuildings. The maintenance and repair of barns and other agricultural buildings, which contribute to agrarian or rural character, is specifically and strongly encouraged.	A	A	A	A	N/A	N/A	N/A	N/A
Greenbelts and wildlife corridors. Any significant development other than farm or forestry operations should maintain open space in the form of greenbelts or wildlife corridors.	A	A	A	A	N/A	N/A	N/A	N/A
Road surfacing. Roads may be surfaced with non-asphalt (e.g., gravel) materials and drained by roadside ditches in order to maintain rural character. The same is applicable for parking lots, where permitted.	A	A	A	N/A	N/A	N/A	N/A	N/A
Conservation principles. Major subdivisions (6 or more lots), where permitted, are required to follow principles of conservation subdivision and design, either as generally accepted by the planning profession or as specifically stated in city regulations.	N/A	A	A	A	A	A	A	A
Subdivision lot design. When land is subdivided, regular or recurring patterns of lots are required; lot layouts that maintain the formality of existing and nearby property ownership patterns are encouraged to maintain the traditional urban form and grid pattern.	N/A	A	A	N/A	N/A	N/A	N/A	N/A
