B. 
Streets.
1. 
Relation to adjoining streets. The arrangement of rights-of-way in a subdivision shall provide for the continuation of the existing streets or rights-of-way in adjoining areas, unless the Board of Aldermen deems such continuation undesirable for reasons of topography or design. Where streets, subdivision streets or rights-of-way are continuations or extensions of existing street or right-of-way, the width thereof shall be at the same or greater width than the existing street or right-of-way, except that in no case shall the street or right-of-way in the subdivision be of less width than hereinafter provided in Table A[1], set out in Section 510.020 (B).

(3) 
Where rock is known to exist beneath the pavement area and at such depth as to interfere with the jacking of service connections, the Board of Aldermen shall require the completed installation of service connections before any base is applied.
(4) 
In cases where underground utilities are to be provided within the right-of-way of streets they should not be installed under the paved portions thereof, unless deemed necessary by appropriate authority.
b. 
The improvement plans for an adequate drainage system including all necessary open ditches, pipes, culverts, intersectional drains, drop, inlets, bridges and other accessory structures and improvements shall be provided for the proper drainage of all surface water. Cross drains shall be provided to accommodate all natural water flow, and shall be of sufficient length to permit full width roadways and the required slopes. The size for openings to be provided shall be determined by the Rational Method or accepted engineering practice, but in no case shall the pipe be less than twelve (12) inches in diameter. The design of the storm drainage system shall be based on a ten (10) year design frequency. Where any natural watercourse is to be disturbed or blocked, adequate provisions shall be made to handle the water.
