Streets which <br />shall serve as collector and arterial streets shall have a minimum radius of <br />310 feet. Such street may be reduced to a minimum of 240 feet' providing <br />full superelevation is incorporated in the street design. All Municipal State <br />Aid (MSA) roads shall meet current MSA standards for horizontal <br />alignment which is dependant upon design speed. <br /> <br />Street grades shall not exceed 7% for minor and collector streets and 4% for <br />thoroughfares, and in no case shall they be less than 0.4%. Wherever <br />feasible, grades within 30 feet of street intersections shall not exceed 3% <br />and all private driveways providing access to public right-of- 9.50.30 <br />approach to grade level. <br /> <br />Different connecting street gradients shall be connected with vertical curves. <br />Minimum length, in feet, of said vertical curves shall be 100 feet or 20 times <br />the algebraic difference in the percentage of grade of the two adjacent <br />gradients. <br /> <br />Street jogs in minor and service streets shall have a centerline offset of not <br />less than 150 feet. Street jogs in collector streets shall have a centerline <br />offset of not less than 300 feet. <br /> <br />Minor streets shall be so aligned that their use by through traffic will be <br />discouraged. <br /> <br />9.50 Subdivision Regulations <br /> <br />9-27 <br /> <br />March 2003 Draft <br /> <br />-405- <br /> <br /> <br />
