(A) Drives and parking areas shall be designed to provide favorable circulation within the development, uninterrupted flow of vehicular traffic along the public street or streets adjacent to the development, and adequate visibility for the safety of both vehicular and pedestrian traffic. Separate (one-way) drives for ingress and egress may be required when safety and circulation will be more adequately provided.
(B) The location of drives for ingress and egress shall be determined with full consideration given to existing topographical features; the classification, right of way needs, volume and speed of traffic along adjacent public streets or highways; the location of the area to be developed with reference to the location of intersections, retaining walls, drainage structures, and other features that may affect location and design, and proposed public street or highway improvements.
(C) Where a development abuts or contains an existing or proposed arterial street, involving heavy volumes of high speed vehicular traffic, the city may require marginal access streets, or a reverse frontage with restricted and controlled access to the arterial street.
(D) In cases where the development is adjacent to an arterial street and expected volume of vehicular traffic entering the development is significant, the city may require the owner to construct and bear the expense of left turn and/or right turn lane improvements on the public arterial street to provide for continuous and uninterrupted flow of traffic along the arterial street.
(E) Driveway improvements for ingress and egress constructed on public right of way from existing street surface to right of way line shall meet or exceed the following minimum acceptable pavement base and surface designs:
1. Nine inch (9") (compacted thickness) aggregate base course type B, with three inch (3") (compacted thickness) bituminous concrete surface, class I.
2. Six and one-half inch (6.5") nonreinforced concrete pavement, with sawed contraction joints at fifteen foot (15') intervals.
(F) The longitudinal slope on drives exiting on or entering from the public street or highway shall not exceed ten percent (10%).
(G) Where driveway improvements connect to exiting on or entering from the public gutters, the driveway shall be constructed with concrete curbing along both sides of the driveway base and surface with the top of the curb at the same height as the top of the street curb and tapered to zero height at the front edge of the sidewalk. Curbs shall be constructed with ten foot (10') radius, unless otherwise directed by the superintendent of public works.
(H) The concrete used in the construction of the concrete curb and concrete driveway pavement shall have an air content of not less than four percent (4%) or more than seven percent (7%) of the volume of the concrete and shall have a minimum compressive strength of three thousand five hundred (3,500) pounds per square inch at the age of twenty eight (28) days.
