[Ord. No. 2005-03 §480.010, 5-9-2006]
In order to protect the health, safety, morals and general welfare
of the people, the Planning and Zoning Commission will reject any
proposed subdivision located in an area subject to periodic flooding.
Whenever a subdivision is proposed to be located in an area having
poor drainage or other adverse physical characteristics and impairment
and such condition(s) is brought to the attention of the Planning
and Zoning Commission, the Planning and Zoning Commission may approve
the plat, provided the developer binds himself/herself legally to
make such improvements or take such measures as, in the judgment of
the Planning and Zoning Commission, will render the subdivision substantially
safe and otherwise acceptable for the intended use. In this case the
developer shall post with the Commission a surety performance bond,
payable to the City or other security acceptable to the Planning and
Zoning Commission, sufficient to cover the cost of such improvements
as estimated by the Planning and Zoning Commission. Such determinations
by the Planning and Zoning Commission shall not constitute a warranty
or guarantee that these measures will remedy the condition(s).
[Ord. No. 2005-03 §480.020, 5-9-2006]
The subdivision layout shall conform to the official Comprehensive
Plan. Unless otherwise approved by the Board of Aldermen, provision
must be made for the extension of main thoroughfares as designated
by the Planning and Zoning Commission; and other major or collector
streets must provide free circulation within the subdivision and be
open to the public.
[Ord. No. 2005-03 §480.030, 5-9-2006]
The system of streets designated for the subdivision, except
in unusual cases where land use will not justify it or in other unusual
cases, shall connect with streets already dedicated in adjacent subdivisions;
and where no adjacent connections are platted shall in general be
the reasonable projections of streets in nearest subdivided tracts
and shall be continued to the boundaries of the tract subdivided,
so that other subdivisions may connect therewith.
[Ord. No. 2005-03 §480.040, 5-9-2006]
A.
The
following shall be the minimum street right-of-way requirements and
utility easements:
1.
Highways and major thoroughfares. Highways and major
thoroughfares as specified in the official thoroughfare plan and not
less than seventy-two (72) feet in any case.
2.
Collector streets. Sixty (60) feet.
3.
Local streets. Forty (40) feet.
4.
Minor streets, dead-end streets and cul-de-sac streets. All dead-end streets shall terminate in a circular turnaround having
a minimum right-of-way diameter of one hundred (100) feet, unless
the Planning and Zoning Commission approves a "T" or "Y" shaped gravel
space in place of the required turning circle.
5.
Alleys. Alleys, where platted, shall have a minimum
width of twenty (20) feet.
6.
Utility easements.
a.
General. Widths of utility easements, where required
except as provided for in paragraph (b) below, shall be at least twenty
(20) feet wide along front, rear or side lot lines. Easements of adequate
width shall be provided for open drainage channels, where required.
b.
Developments.
(1)
In any case in which a developer installs or causes the installation
of water, sewer, electrical, power, telephone, cable television or
other utility and intends that such service shall be owned, operated
or maintained by a public utility or any entity other than the developer,
the developer shall transfer to such utility or entity the necessary
ownership or easement rights to enable the utility or entity to operate
and maintain such service.
(2)
All planned residential, commercial, industrial or PUD districts
or any other development that involves a recorded final plat shall
provide the following utility easements:
(a)
Along any State, County, private or subdivision road a twenty
(20) foot wide easement shall be established. Where the development
is located on both sides of a right-of-way, the utility easements
shall be located on both sides of the roadway.
(b)
Along any side or rear property line, other than those adjacent
to a roadway, a minimum of ten (10) feet of utility easement shall
be established. Where two (2) lots are adjacent, this will create
a total utility easement of twenty (20) feet.
(3)
In all unsubdivided developments, utility easements shall either be established by a recorded instrument similar to the requirements of Subsection (6)(b)(2); or it shall be established that the entire common or open space area within the development is available as a general utility easement.
(4)
No building or structure shall be permitted within the boundaries
of any general utility easement. Utility easements that are owned
or controlled by a single entity can only be built in with specific
permission by that entity.
[Ord. No. 2005-03 §480.050, 5-9-2006]
A.
Minimum
pavement widths, required to be installed at subdivision expense,
shall be as follows:
1.
Major thoroughfares and collector streets. Twenty-four
(24) feet. In the case of a major thoroughfare or collector street
requiring pavements wider than twenty-four (24) feet, the matter of
financial and other arrangements for installing such wider pavements
at the time the developer will make the improvements shall be taken
up by the developer with the officials having jurisdiction.
2.
Minor, local, dead-end and cul-de-sac streets. Twenty-four
(24) feet. The driving surfaces of a turning circle at the end of
a dead-end street shall have a minimum outside diameter of one hundred
(100) feet. A "T" or "Y" shaped driving surface, when approved by
the Planning and Zoning Commission in place of a turning circle, shall
extend entirely across the width of the street right-of-way, except
for sidewalk space, and shall be at least ten (10) feet wide with
the flared portion rounded by minimum radii of twenty (20) feet.
3.
Alleys and service drives. Twenty (20) feet.
[Ord. No. 2005-03 §480.060, 5-9-2006]

The
size, shape and orientation of lots shall be appropriate for the location
and physical character of the proposed subdivision and for the type
of development contemplated in compliance with the applicable zoning
ordinance or regulations.
1.
Depth. Excessive depth in relation to width shall
be avoided (a proportion of 1:1 or 2:1 will normally be considered
appropriate, except in the case of narrow lots).
3.
Width. Lots for residential purposes shall have
sufficient width at the building setback lines to permit compliance
with side yard or distance requirements of the applicable zoning ordinance
or regulations and still be adequate for a building of practicable
width.
4.
Double frontage. Unless otherwise provided herein,
double frontage lots and reversed frontage lots shall be avoided.
5.
Side lot lines. Where practicable, side lot lines
shall be approximately at right angles to the right-of-way line of
the street on which the lot faces.
6.
Corner lots. Corner lots for residential use shall
be platted wider than interior lots to permit compliance with the
yard and setback requirements for the applicable Section of this Chapter.
7.
Minimum lot size. Where not otherwise determined
by applicable Section of this Chapter, the minimum lot size for residential
purposes shall be nine thousand (9,000) square feet with a minimum
