B. 
Lot Dimensions.
1. 
Lot dimensions shall comply with the minimum dimensional standards of the applicable zoning district.
2. 
The minimum lot width and minimum lot area for cul-de-sac lots may be increased to ensure adequate spacing between driveways, in accordance with the Engineering and Plan Preparation Manual for Public Facilities (Title V, Appendix A).
3. 
Where lots are more than double the minimum required lot area for the zoning district, the City may require that such lots be arranged so as to allow further subdivision and the opening of future streets where they would be necessary to serve such potential lots in compliance with these regulations.
4. 
In general, side lot lines shall be at right angles to street lines (or radial to curving street lines) unless a variation from this rule will result in a more desirable street or lot plat.
5. 
Dimensions of corner lots shall be of such dimension to allow for erection of buildings, observing the minimum front yard setback from both streets.
6. 
Depth and width of properties suitable for business, commercial or industrial purposes shall be adequate to provide for the off-street parking and loading facilities required for the type of use and development contemplated as established in the zoning regulations.
7. 
Double-frontage and reversed-frontage lots shall be avoided except where necessary to overcome specific disadvantages of topography or orientation. Where double-frontage and reversed-frontage lots are allowed, driveways are only permitted on one (1) frontage.
8. 
Flag lots and other irregularly shaped lots are discouraged.
C. 
Buffers From Railroads And Major Streets.

Where Future Resubdivision Is Indicated.

Whenever a parcel of land is subdivided and the subdivision plat shows one or more lots having the potential for additional subdivision under the provisions herein, the City may require that such parcel of land provide for the future opening of streets or the ultimate extension of adjacent streets. Easements providing for the future opening and/or extension of such streets may be made a condition of plat approval. See also Section 430.270, Future Extension Of Streets.

The lengths, widths and shapes of blocks shall be such as are appropriate for the locality and the type of development contemplated.
C. 
Blocks in residential subdivisions shall have sufficient width to provide for two (2) rows of lots of appropriate depth. Exceptions to this prescribed block width shall be permitted in blocks adjacent to major streets, railroads, waterways or subdivision property lines.
D. 
Pedestrianways or crosswalks, of not less than ten (10) feet of right-of-way, may be required through the center of blocks more than eight hundred (800) feet long where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation or other community facilities.

1. 
The subdivision of lots so as to back onto the primary arterial and front onto a parallel local street; no access shall be provided to a subdivision lot directly from the primary arterial. Screening shall be provided in a buffer strip of land to be deeded to the City along the rear property line of such lots.
2. 
A series of cul-de-sac, U-shaped streets or short loops entered from and designed generally to intersect at right angles to such streets.
3. 
A secondary access or service road separated from the primary arterial by a planting or grass strip and having access thereto at suitable points.
