(a) 
The length of a block shall be considered to be the distance from property corner to property corner measured along the property line of the block face:
(1) 
Of greatest dimension; or
(2) 
On which the greatest number of lots face.
(b) 
The width of a block shall be considered to be the distance from property corner to property corner measured along the property line of the block face:
(1) 
Of least dimension; or
(2) 
On which the fewest number of lots face.
(c) 
The length, width and shapes of blocks shall be determined with due regard to:
(1) 
Provision of adequate building sites suitable to the special needs the type of use contemplates;
(2) 
Zoning requirements as to lot sizes and dimensions;
(3) 
Needs for convenient access, circulation, control and safety of street traffic.
(d) 
In general, intersecting streets should be provided at such intervals as to serve traffic adequately and to meet existing streets or customary subdivision practices. Where no existing subdivision controls, the block lengths should not exceed 1,320 feet. Where no existing subdivision controls, the blocks should not be less than 500 feet in length; however, in cases where physical barriers, property ownership, or individual usage creates conditions where it is appropriate that these standards be varied, the length may be increased or decreased to meet existing conditions, having due regard for connecting streets, circulation of traffic and public safety.
(e) 
Where long blocks in the vicinity of a school, park or shopping center are platted, the city council may require a public walkway near the middle of long blocks or opposite a street that terminates between the streets at the ends of the block. If required, the walkway shall not be less than four feet, constructed of concrete, and shall have a concrete walk of a minimum width of four feet through the block from sidewalk to sidewalk, or curb to curb, or if no street, to the property line adjacent to school, park or shopping center.
[Ord. No. 819-97, § 11(E), 6-10-1997]
(a) 
The lot arrangement and design shall be such that all lots will provide satisfactory and desirable building sites, properly related to topography and the character of surrounding development.
(b) 
All side lines of lots shall be at approximately right angles to straight street lines and radial to curved street lines except where a variation to this rule will provide a better street and lot layout.
(c) 
No lot shall have less area of width at the building line than is required by the zoning regulations that apply to the area in which it is located.
(d) 
Lots shall be consistent with zoning regulations. Proposed uses shall be shown on the preliminary plat.
(e) 
Residential building lines shall be shown on all lots in the subdivision but not less restrictive than the zoning ordinance.
(f) 
Double-frontage lots and flag lots are prohibited. The city council may grant an exception from this prohibition only if the council determines that all of the following conditions are met: (1) a tract has no other reasonably viable use; (2) the lack of other reasonably viable uses was not self-imposed by either the current or a previous owner of the property by platting, replatting or subdivision of adjacent property; (3) no adjacent lots which are zoned for single-family residential use are adversely affected; and (4) the owners of all adjacent lots which are zoned for single-family residential use consent in writing to the creation of the proposed lot.
