§ 7.3. [Curves in streets.]

Where a deflection angle of more than ten (10) degrees in the alignment of a street occurs, a curve of reasonably long radius of curves shall not be less than three hundred (300) feet.

Streets shall be platted to allow two (2) tiers of lots with an alley between. Intersecting cross streets may not be more than one thousand two hundred (1,200) feet apart, nor less than three hundred (300) feet apart.

In blocks over one thousand (1,000) feet in length the planning commission may require a public crosswalk of not less than a ten (10) foot right-of-way, and having not less than six (6) foot concrete walk.

Streets shall be platted with appropriate regard to the county roads, lake areas and other topographical features lending themselves to attractive treatment.

Where plats are presented for approval which adjoin unplatted property, the owner of the proposed subdivision shall provide his pro rata part of boundary streets.
