The most common examples of driveways and approaches are available from the City Engineer, entitled “Driveway Standards.” These standards will apply in majority of cases because many conditions can be derived from each figure. However, there will be exceptional situations and borderline cases where the standards and guides do not apply. In such instances, alternate standards will be used. The next lowest functional type will serve as the alternate dimensions for each functional type (i.e., the alternate dimensions for arterials are the dimension for collectors). The use of alternate dimensions will be subject to the approval of the City Engineer and such approval should precede the filing of permit application. Additional standards which will be required are as follows:
(A) Entrance and exit only driveways.
(1) This type of driveway is not highly recommended for a divided roadway. However, the entrance and exit driveways do have a purpose and when warranted use the following dimensions:
(a) Minimum width = 11 feet.
(b) Maximum width = 17 feet.
(2) In order to control entrance and exit drives, they must be properly signed. This shall be the responsibility of the property owner.
(B) Number of driveways and spacing. Driveway spacing is largely dependent on land use and zoning, and as a result, it is difficult to develop definite standards. Although from past experience and a literature review on this subject, not more than two driveways are generally needed to serve a tract of land. Additional policies are as follows:
(1) Arterials. Frontage roads are encouraged but where this is not feasible a minimum spacing of 150 feet is required between adjacent property owners. Also, as a general rule, if the frontage is 100 feet or less, only one driveway will be permitted.
(2) Collectors. A minimum spacing of 100 feet is required and generally only one driveway per 100 feet of frontage will be allowed.
(3) Local. No minimum spacing is required; however, only one driveway per lot will be allowed.
