(1) Comply with Comprehensive Plan. The arrangement, character, extent, width, grade and location of all streets shall conform to the Ida Grove comprehensive plan and shall be considered in their relation to existing and planned streets, to topographical condition, to public convenience and safety; and in their appropriate relation to the proposed uses of the land to be served by such street.

No street grade shall be less than one-half percent.

(3) Minor Street Layout. Minor streets shall be so laid out that their use by through traffic will be discouraged.

(4) Frontage Roads. Where a proposed subdivision is adjacent to or contains an existing or proposed major or controlled access highway or street, provision shall be made for a marginal access street (frontage road) approximately parallel and adjacent to the highway, or lots shall back up to the major highway or street and have access only to the minor street.

(5) Access Control. Reserve strips controlling access to streets shall be prohibited unless their control is definitely placed in the city under conditions approved by the plan commission.

(8) Minimum Radius. For major streets the minimum radius of curvature shall be 300 feet on the centerline and for minor streets, 60 feet.

(9) Intersections. Streets shall be laid out so as to intersect as nearly as possible at right angles and no street shall intersect any other street at less than 60 degrees.

(10) Half Streets. Half streets shall be prohibited except where essential to the reasonable development of the subdivision in conformity with the other requirements of these regulations or where it is found to be practicable to require the dedication of the other half when adjoining property is subdivided. Wherever a half street is adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract.
