(A) Minimum right-of-way widths and pavement widths (face to face of curb) for each type of public street or road shall be as follows:
Type of Street | Right-of-way Width (Ft.) | Roadway Width (Ft.) |
Thoroughfare | 120 | As determined by traffic needs |
Collector street | 80 | 44 |
Commercial or industrial service street | 60 | 36 |
Minor street | 60 | 34 |
Marginal access street | 60 | 34 |
*Cul-de-sac street | 40 | 34 |
*Cul-de-sac turn around | 55 foot radius | 45 foot radius |
* A ten (10) foot snow/utility easement is required along front property lines.
(B) Where a subdivision abuts or contains an existing street of inadequate width, sufficient additional width shall be provided to meet the above standards.
(C) Additional right-of-way and roadway widths may be required to promote public safety and convenience when special conditions require it or to provide parking space in areas of intensive use.
(D) Extensions of existing streets with lesser right-of-way than prescribed above may be permitted by variance in special cases.
(E) Restriction of access. Access of minor streets onto state and county state aid highways, shall be discouraged at intervals of less than five hundred (500) feet.
(F) Street jog. Street jogs with center-line offsets of less than one hundred fifty (150) feet shall not be allowed.
(G) Deflection. When connecting street lines deflect from each other at any one (1) point by more than ten (10) degrees, they shall be connected by a curve with a radius of not less than one hundred (100) feet.
(H) Grades. Centerline gradients shall be at least four-tenths percent (0.4%) and shall not exceed the following:
Classification | Gradient (In Percent) |
Thoroughfares and collector street | 5 |
Minor and service streets | 8 |
(I) Vertical curves. Different connection street gradients shall be connected with vertical curves. Minimum length, in feet, of these curves shall be twenty (20) times the algebraic difference in the percent of grade of the two (2) adjacent slopes.
(J) Angle of intersection. The angle formed by any intersecting of streets shall not be less than sixty (60) degrees with ninety (90) degree intersections preferred.
(K) Size of intersection. Intersections of more than four (4) corners shall be prohibited.
(L) Corner radii for roadways. Roadways of street intersections shall be rounded by a radius of not less than fifteen (15) feet. Roadways of alley-street intersections shall be rounded by a radius of not less than six (6) feet. Corners at the entrances to the turnaround portions of a cul-de-sac shall be rounded by a radius of not less than fifteen (15) feet.
