1317.05 CONSTRUCTION STANDARDS
(a) Compliance with Subdivisions Regulations. All driveways shall
conform to Section 1193.11 set forth in the Planning and Zoning
Code.
(b) Location. The driveway shall be so located that all portions
therefore sahlI come within the limits of lot lines extended to
the existing curb or pavement, unless Council by special
resolution shall authorize a different location. Such resolution
shall specify the location authorized. In case water dydrants,
light standards, telephone poles or other existing structures
conflict with the location decided upon, the Building Inspector
may require such structure to be removed, provided that removal
is practicable.
The property owner shall deposit in advance with the owner of
such structures a sum sufficient to cover the full cost of
removal and relocation.
(c) Removal of Curb. The minimum length of removal of existing curb
shall be sixteen feet. In cutting the existing curb, care shall
be taken so that the cut shall be vertical and at right angles
to the line of curb. Five feet shall be the minimum length of
the block or blocks of curb left in place, otherwide a full block
of existing curb shall be removed and replaced. Replaced work
shall conform in all respects in character and kind to existing
work. The minimum width of driveway, from the curb line to the
lot line, shall be ten feet.
(d) Character of Work. All driveways shall be paved with concrete
from the back of the curb line, or if there be no curb, from the
street pavement to the lot line. Asphaltic concrete will be
permitted where there are no curbs. Concrete shall comply with
the provisions of Section 1317.06(g) and shall have a minumum
depth of six inches throughout. Asphaltic concrete shall be of
a type and depth as to have sufficient stability to withstand the
use to which the driveway may be put. Where concrete sidewalks
, are in place in front of the property, that portion of the drive-
way crossing the sidewalk section shall be constructed of
concrete. To provide for expansion, a one-half inch pre-moulded
expansion joint extending the full section width of the curb and
gutter shall be placed at each side where the driveway joins
the curb and gutter shall be placed at each side where the
driveway joins the existing curb and also in the center of the

sufficient size as determined by the Building Inspector shall be
placed under the drive.
(e) Existing Structures. Existing drain tile shall be maintained in
workable condition and if disturbed shall be properly replaced.
If no drain tile exists, a drain tile shall be inserted. Where
electric cable exists, a two-inch fiber duct shall be placed
around the cable in such a manner as to leave the cable free to
be pulled and replaced. If no electric cable exists and if the
street is improved with curbs and gutters, a two-inch duct shall
nevertheless be inserted to care for future cables. Valve boxes,
land monuments and any existing structures encountered shall be
properly protected and cared for.
(f) Adjustments. Where the sidewalk is adjacent to the curb, the
Building Inspector may make such adjustments to Appendix A of the
Dublin Subdivision Regulations set forth in Title One of Part
Eleven as are necessary to prevent damage to the street, curb or
or sidewalk and provide for as smooth an entrance as possible.
(g) Limitation on width and number. Driveway width and number
requirements shall be provided as required by Section 1193.11 of
the Planning and Zoning Code.
MEMORANDUM
TO: City Council Members
FROM: Tim Hansley, City Manage~
DATE: February 1, 1989
SUBJECT : Driveway Width Regulations
Summary and Action Recommended:
Based on the Community's desire for three-car garages and increased
driveway widths, the Planning Department saw the need to review our
current regulations and potentially update our Ordinance regarding
residential driveways. Staff researched the problem by contacting other
cities within the Columbus area, reviewed literature on other city
ordinances in other states, and conducted field evaluations. Existing
sections of Dublin's Codified Ordinances relating to driveways were
reviewed as well, including commercial driveway widths and recommen-
dations regarding their regulations are included. Generally, it was
concluded that the Dublin Ordinance is appropriate, as is, with some
modifications and stricter enforcenent.
Issue:
Currently, Dublin regulates its driveway widths under Section
1317.05, Construction Standards, and Section 1193.11, Driveways, of the
Codified Ordinances. While reviewing the ordinances, Staff found two
problems. First, there is a lack of consistency in the standards and
there are no cross-references between the two sections pertaining to
driveway widths. Section 1317.05(g) (1) states that "No driveway in a
residential zoning district...sha11 exceed twenty-six feet at the curb
line.. . " Section 1193.11(d), however, states that "... (residential)
driveways shall have a...maximum width of twenty-five feet..." A second
problem found is that many single-family home building plans show
three-car garages with widths which exceed twenty feet. Furthermore,
the owners of these homes have expressed the desire for increased
driveway widths to allow for ease in access to their three-car garages.
Data Collections/Findings:
To research how other cities regulate their residential driveway
widths, Staff contacted the cities of Westervil1e, Upper Arlington,
Hilliard, Gahanna, and Columbus. Generally speaking, these cities have
standards similar to Dublin's for two-car garages/driveways, but they
have yet to alter their regulations to allow for three-car garages/
driveways. Upper Arlington and Hilliard, however, provide for review
by their Boards of Zoning Appeals for variances to their Codes.
Staff also contacted the American Planning Association who provided
literature on general driveway standards and design, and regulations
,

adopted in other states including Oregon, Illinois, New Jersey, and
Nevada. Unfortunately, however, most of the information was limited and
did not pertain to Dublin's problem, as intended.
Overall, the literature only referenced the curb-cut width, without
acknowledging the driveway width. Moreover, most other cities tend to
combine their standards on commercial and residential driveways.
Additionally, Staff reviewed the texts on architectural standards and
roadway design.
Field evaluations were made of existing driveways in Dublin. Staff
randomly inspected two- and three-car garages/driveway widths within the
City. Measurements were made at the curb cut, street right-of-way line,
and garage. Finally, staff reviewed pertinent sections of the Code
relating to driveway regulations.
Analysis:
Based on the interpretation of collected data, Staff made a number
of recommendations. First, prior enforcement of Code was found
inconsistent. Many driveways were found wider than regulations allow
and many were being used as additional parking spaces. Second, many
driveways have excessive pavement-to-green space ratios found to be
functionally and aesthetically inappropriate. Third, many driveways
were found encroaching upon the three-foot minimum distance to property
line. Finally, two sections of the Codified Ordinances which referenced
driveways were found inconsistent with each other.
Considerations:
Staff considered and applied numerous approaches to aid in the
regulation of driveway widths, prior to reaching a conclusion. The use
of radius curves, as an alternative to flared curb cuts, was considered
as a way to ease turning access to drives without widening curb cuts.
Staff also evaluated the provision of varying driveway width based on
the amount of property frontage. Additionally, Staff tested the theory
of controlling the amount of pavement in proportion to green space
against existing conditions. The stringent control of driveway design
and layout was also considered as a method in achieving consistent
standards.
Conclusion:
After serious consideration of many methods, Staff concluded that
there is no general standard applicable to all lots within Dublin.
Moreover, the current regulations were found to be acceptable, if
enforced, and if modified. With many revisions to the current
standards, Staff found the following recommendations should be
incorporated into Section 1193.11:
1) Provide that no residential driveway shall exceed twenty-six
feet in width at the curb line including two 3-foot flairs, one
on each side,
2) Provide that no residential driveway shall exceed twenty feet
in width at the street right-of-way line,
;
3) Provide that no residential driveway shall exceed the width of
the garage,
4) Provide that residential driveways for front-loading garages
shall taper in width from the garage to the street right-of-way,
5) Provide that no residential driveway shall be located within
three feet of the property line,
6) Provide that curb cuts or points of ingress/egress shall be
limited to one per single-family residence,
7) Provide that no commercial driveway shall exceed 30 feet in
width at the street right-of-way line,
8) Provide that the approach for a commercial driveway include two
la-foot minimum radii,
9) Provide that Planned Unit Developments be affected by the
regulations,
10) Establish a review process by Staff for those desiring an
exception to the standards, and
11) Establish an appeals process to the Board of Zoning Appeals.
Within Section 1317.05:
1) Provide that all driveways shall conform to Section 1193.11 of
the Code,
2) Provide that all work be subject to the approval of the City
Engineer who may order the removal of any work which does not
comply,
3) Provide that the City Engineer may make adjustments to Appendix
A of the Dublin Subdivision Regulations set forth in Title One
of Part Eleven as are necessary to prevent street, curb, or
sidewalk damage, and
4) Provide that driveway width and number requirements be provided
as required by Section 1193.11 of the Planning and Zoning Code.
