(a)   Streets shall level off to a grade not exceeding three percent for a distance of not less than 100 feet from each side of a local to local street intersection.  The Municipal Engineer may require a distance greater than 100 feet, in accordance with accepted practice, for intersections involving higher order streets.
   (b)   The maximum vertical grades of streets shall not exceed ten (10%) percent for local streets, seven (7%) percent for collector streets, and six (6%) percent for arterial streets.
   (c)   The grading of the roadway shall extend the full width of the right of way. Tree lawns shall be graded at a gradient of not less than two (2%) percent or more than five (5%) percent upward from the curb to the sidewalk or property line.
   (d)   Streets shall be graded for the positive drainage of storm water. For drainage purposes street grades shall be not less than one (1%) percent in order to provide adequate surface drainage. However, the Approving Authority, following consultation with the Municipal Engineer, may permit a minimum street grade of one-half of one (0.5%) percent where necessary because of topographic or other conditions.  Storm sewers shall be provided and installed with adequate capacity to handle drainage from the street and such storm water as may be directed thereto from adjacent lands (see Chapter 929 (Storm Sewer Regulations)).
   (e)   After the street base finish grading has been completed, and prior to the installation of the street pavement, the developer’s engineer or surveyor shall provide to the Authority Having Jurisdiction, written certification based on an actual field survey that the street base field location, grade elevations and cross slope elevations comply with the plans approved by the Municipality.
