A.
Number of driveways.
(1)
Access for an individual lot or for contiguous lots under the same ownership shall consist of either a single two-way driveway or a paired driveway system wherein one driveway is designed, and appropriately marked, to accommodate ingress traffic and the other egress traffic.
(2)
For developments that can demonstrate that their combined driveway approach volumes (entering and exiting) will exceed 3,000 during an average day (or will be used by 300 vehicles during the peak hour of traffic for either the street or the use), and lacking access to a secondary street, a second driveway may be allowed along the major street provided that the additional driveway can meet the spacing requirements.
(3)
For a lot with frontage exceeding 300 feet, or where a lot has frontage on at least two streets, an additional driveway may be allowed, provided that a traffic analysis is submitted by the applicant showing that conditions warrant an additional driveway and that all driveways meet the spacing requirements.
(4)
Certain developments generate enough traffic to warrant consideration of an additional driveway to reduce delays for exiting motorists. Where possible, these second access points should be located on a side street, shared with adjacent uses or designed for right turn-in, right-turn-out only movements. Development characteristics that warrant consideration of an additional driveway are as follows:
(a)
Family developments with over 500 units.
(b)
Grocery store of over 30,000 square feet (GFA).
(c)
A shopping center with over 40,000 square feet (GFA).
(d)
A hotel or motel with over 400 rooms.
(e)
Industrial developments with over 300,000 square feet (GFA) or 350 employees (although a secondary entrance for trucks should be allowed).
(f)
Warehouses of over 750,000 square feet (GFA) or 350 employees.
(g)
A mobile home park with over 600 units.
(h)
General office building of 150,000 square feet (GFA) or 500 employees.
(i)
Medical office building of 60,000 square feet (GFA) or 200 employees.
(j)
Fast-food restaurant of over 6,000 square feet (GFA).
(k)
Sit-down restaurant of over 20,000 square feet (GFA).
B.
Driveway spacing.
(1)
Driveway spacing will be based on posted speed limits along the property frontage as indicated in the following table:
Posted Speed Limit (MPH) | Recommended Driveway Spacing (feet) |
|---|---|
30 | 125 |
35 | 150 |
40 | 185 |
45 | 230 |
50 | 275 |
55 | 350 |
Measured center line to center line | |
(2)
If the amount of street frontage is not sufficient to meet these criteria, the driveway shall be constructed adjacent to the property line furthest from the intersection.
(3)
In order to minimize left-turn conflicts, driveways shall be offset a minimum of 150 feet, measured center line to center line, or aligned with those across the street.
(4)
Where lots have frontage or access on more than one roadway, access shall be provided from the lesser traveled street. Where spacing requirements can be met, high traffic volumes will be generated, or the subject side street is inappropriate for nonresidential traffic, access onto the main roadway will be considered.
(5)
In the case of expansion, alteration or redesign of an existing development where existing driveways do not comply with the guidelines set forth herein, the closing, relocation, or redesign of the driveway may be required.
C.
Shared access. Shared access between lots through frontage roads, rear service drives, alleys and shared drives, or driveway placement or closure of an existing driveway so as to facilitate future shared access between lots, shall be encouraged where feasible and appropriate.
