f. Stopping Sight Distance.

g. Grades.

Maximum grade in itself is not a complete design control. It is also necessary to consider the length of a particular grade in relation to desirable vehicle operation.

For streets in commercial and industrial areas gradient design should be less than eight (8%) percent; desirably it should be less than five (5%) percent, with emphasis on still flatter gradients.

In order to provide for proper drainage the minimum grade that should be used for streets with outer curbs is five (5%) percent.

h. Minimum Centerline Radius.

i. Cul-de-sac Turnaround. A local street open at one (1) end only should have a special turning area at the closed end. This turning area may be of "L," "T" or circular shape with dimensions as appropriate for the type of vehicle expected. The commonly used circular form should have a minimum curb radius of thirty-five (35) feet in residential areas. Generally, cul-de-sacs should not be over six hundred (600) feet in length.

j. Clearance to Obstructions. On all streets, a clearance of at least two (2) feet shall be provided between the face of curb or edge of shoulder and obstructions, such as utility poles, lighting poles, and fire hydrants.

k. Milling and Repaving. Milling and repaving, curb to curb, of the street at a project frontage shall be required if four (4) or more adjacent gas, electric, water and/or sewer utility trenches are proposed. Milling and repaving, curb to curb, of the street for the entire block length, shall be required if six (6) or more gas, electric, water and/or sewer utility trenches are proposed within the same tax block or within the tax blocks across from each other on the street.
