[Ord. No. 2480, 5-8-2023]
A.
The area of the lots shall be determined by zoning district regulations,
subject to the availability of public sewer and a public water supply.
Prior to the submission of a preliminary plat, the subdivider shall
obtain a determination from the engineer having jurisdiction as to
whether adequate public sewer and water supply are available.
C.
If the proposed subdivision is serviced with a public water supply,
but not with a public sewer system, the preliminary plat shall be
prepared on the basis of minimum two (2) acre lots; provided, however,
that additional lot area may be required if the area has or is suspected
of having a high water table or if soil conditions prove to be unsuitable
based on tests.
D.
All proposed private sewer systems shall be reviewed for approval
by the Smithville Wastewater Management District. All such individual
devices and systems shall be constructed and maintained in accordance
with the regulations and requirements of the Missouri State Board
of Health.
[Ord. No. 2480, 5-8-2023]
A.
Length. Intersecting streets (which determine block length) shall
be provided at such intervals as to serve cross traffic adequately
and to meet existing streets in the neighborhood. In residential districts
where no existing plats are recorded, the blocks shall not exceed
one thousand two hundred (1,200) feet in length, except that a greater
length may be permitted where topography or other conditions justify
a departure from this maximum. In blocks longer than eight hundred
(800) feet, pedestrian ways and/or easements through the block may
be required near the center of the block. Such pedestrian ways or
easements shall have a minimum width of ten (10) feet. Blocks for
business use should normally not exceed six hundred (600) feet in
length.
B.
Width. In residential development, the block width shall normally
be sufficient to allow two (2) tiers of lots of appropriate depth.
Blocks intended for business or industrial use shall be of such width
and depth as may be considered most suitable for the prospective use.
[Ord. No. 2480, 5-8-2023]
A.
Relations To Adjoining Street System. The arrangement of streets
in new subdivisions shall make provisions for the continuation of
the principal existing streets in adjoining additions (or their proper
projection where adjoining property is not subdivided), insofar as
they may be necessary for public requirements, as shown on the major
street plan component of the Comprehensive Plan. The width of such
streets in new subdivisions shall not be less than the minimum street
widths established herein. Alleys, when required, and street arrangement
must also be such as to cause no hardship to owners of adjoining property
when they plat their land and seek to provide for convenient access
to it. Whenever there exists a dedicated or platted half street or
alley adjacent to the tract to be subdivided, the other half of the
street or alley shall be platted and dedicated as a public way.
B.
Street Names. Streets that are obviously in alignment with others
already existing and named shall bear the same alpha-numeric designation
adopted by the Board of Aldermen.
C.
Arterial And Collector Streets. Major streets through subdivisions
shall conform to the Major Street Plan as adopted by the Planning
Commission and the Governing Body.
D.
Local Streets. Minor streets shall be so designed to discourage through
or non-local traffic.
E.
Cul-De-Sacs. An adequate turnaround of not less than a fifty (50)
foot radius right-of-way shall be provided at the closed end of a
dead-end street longer than one (1) lot in length. Such local street
segment shall not exceed five hundred (500) feet in length from the
centerline of an intersection of a cross street to the center of the
cul-de-sac; except for suburban, large-lot development in the "R-S"
District, which shall not exceed one thousand two hundred (1,200)
feet.
F.
Right-Angle Intersections. Under normal conditions, streets shall
be laid out to intersect, as nearly as possible, at right angles.
Where topography or other conditions justify a variation from the
right-angle intersection, the minimum angle shall be sixty degrees
(60°).
G.
Streets Adjacent To A Railroad Right-Of-Way, Limited Access Freeway,
Or Principal Highway. Where lots front or side, but do not back, on
railroad right-of-way, limited access freeways, or principal highways,
a marginal access street or frontage road may be required parallel
and adjacent to the boundary of such rights-of-way. The distance from
said rights-of-way shall be determined, with due consideration, to
minimum distance required for approach connections to future grade
separation.
H.
Half Streets. Dedication of half streets will not be approved, except
where it is essential to the reasonable development of the subdivision
and in conformity with the Major Street Plan and other requirements
of these Regulations.
I.
Alleys. Alleys may be required in commercial and industrial districts.
Dead-end alleys shall be avoided, wherever possible. Alleys may be
required in certain residential areas.
J.
Minimum Requirements. The right-of-way grades, horizontal curves,
and vertical curves for streets and alleys dedicated and accepted
shall not be less than the minimum for each classification as follows:
K.
Additional Requirements. When existing or anticipated traffic on
arterial and collector streets warrants greater widths of rights-of-way,
the additional width shall be dedicated.
L.
Street Alignment. On streets with reverse curves, an appropriate
tangent shall be provided between curves to permit a smooth flow of
traffic.
M.
Intersections. Local non-aligned intersections shall be spaced at
a minimum of one hundred fifty (150) feet (centerline to centerline).
Collector intersections shall be spaced at a minimum of five hundred
(500) feet (centerline to centerline).
N.
Drainage Easements. Drainage easements may be required, in addition
to street rights-of-way, where the street or streets adjoin or are
parallel with streams or drainage areas or where lots back on where
said drainage exists. The width of such drainage easement shall be
determined by the engineer having jurisdiction who shall notify the
Planning Commission of his/her recommendation in writing.
O.
Sight Triangle. A sight triangle is a triangular area at the intersection
of two (2) streets in which nothing shall be erected, placed, planted
or allowed to grow high enough above the elevation of the adjacent
roadway to constitute a sight obstruction. The area included in a
sight triangle shall be bounded on two (2) sides by the centerlines
of each street, and on the third side by a line connecting the two
(2) lines. The unobstructed sight distance must be sufficient to allow
the operators of vehicles approaching the intersection simultaneously
to see each other in time to prevent collisions. The sight distance
must be related to vehicle speeds and to the resultant distances traversed
during perception, reaction time and braking. (See the Transportation
and Traffic Engineering Handbook, Second Edition, Institute of Transportation
Engineers, 1986, or most recent edition.)
[Ord. No. 2480, 5-8-2023]
A.
Minimum lot width shall be as specified in the district regulations
of the City of Plattsburg Zoning Regulations;[1] however, corner lots shall be twenty (20) feet wider than
that required in those regulations. Lot width shall be measured at
the building setback line.
B.
Minimum depth shall be one hundred (100) feet. Lot depth shall be
measured through the center of the lot and shall be perpendicular
to the property line or radial to the property line on curved streets.
D.
In subdivisions where septic tanks or other individual sewage disposal
devices are to be installed, the size of all lots included in the
subdivision shall be subject to regulations as set out in this Section
under water and sewer.
E.
In subdivisions where private water supply is by well or other means,
the size of all lots included in the subdivision shall be subject
to regulations as set out in this Section under water and sewer.
F.
All side lot lines shall bear sixty degrees (60°) to ninety degrees
(90°) from the street right-of-way line on a straight street or
from the tangent of a curved street.
G.
Corner lots, in residential subdivisions, shall observe the same
front yard setback on both streets.
H.
Double frontage lots shall be avoided unless, in the opinion of the
Planning Commission, a variation to this rule will give better street
alignment and lot arrangement.
I.
Every lot shall abut on a street other than an alley.
L.
The depth of the lot shall not exceed three (3) times its width.
[Ord. No. 2480, 5-8-2023]
Where alleys are not provided, permanent, continuous easements
of not less than ten (10) feet in width shall be provided on each
side of all rear lot lines, and on side lot lines, where necessary,
for utility poles, wires, conduits, storm and sanitary sewers, gas,
water, and heat mains, and other public utilities.
[Ord. No. 2480, 5-8-2023]
In subdividing land or re-subdividing an existing plat, due
consideration should be given by the subdivider to the dedication
or reservation of suitable sites for schools, parks, playgrounds,
or other public recreational areas or open spaces. Any areas so dedicated
or reserved shall conform as nearly as possible to the Comprehensive
Plan. All areas to be reserved for, or dedicated to, public use shall
be indicated on the preliminary plat in order that it may be determined
when and in what manner such areas will be dedicated to or acquired
by the appropriate agency. A written statement from the Board of Education
may be required to be submitted by the subdivider indicating whether
or not a school site in the proposed subdivision is desired.
[Ord. No. 2480, 5-8-2023]
In the interest of public safety and for the preservation of
the traffic-carrying capacity of the street system, the Planning Commission
shall have the right to restrict and regulate points of access to
all property from the public street system. Such restrictions shall
be indicated on the final plat.
[Ord. No. 2480, 5-8-2023]
The design of the subdivision shall provide for efficient traffic
flow, proper mixing of land uses, and a logical link between surrounding,
existing development and the proposed layout. The Comprehensive Plan
should be used as a guide in determining if the design of the proposed
subdivision is proper. The Planning Commission shall have the authority
to deny a plat or request redesign if, in its opinion, the layout
is not suitable for the site.
