[R.O. 2013 §410.050; CC 1991 §405.050; CC §43.200]
Whenever the area is divided into lots containing one (1) or
more acres and there are indications that such lots will eventually
be resubdivided into smaller building lots, consideration must be
given to the highway, street and lot arrangement of the original subdivision
so that additional minor streets can be opened which will permit a
logical arrangement of smaller lots. Easements providing for the future
opening and extension of such streets may at the discretion of the
Board of Aldermen be made a requirement of the plat.
[R.O. 2013 §410.060; CC 1991 §405.060; CC §43.210]
The arrangement of highways and streets in new subdivisions
shall make provisions for the continuation of the existing highways
and major streets (or their proper projection where adjoining property
is not subdivided) insofar as they may be deemed necessary by the
Board of Aldermen for public requirements. The width of such highways
and streets in new subdivisions shall not be less than the minimum
street widths established herein. The highway and street arrangements
shall also be such as to avoid hardship to owners of adjoining property
when they plat their own land and seek to provide for convenient access
to it.
[R.O. 2013 §410.070; CC 1991 §405.070; CC §43.215]
When the area to be subdivided adjoins a railroad right-of-way,
the intersection of the centerline of any street or highway paralleling
the railroad with that of any street that crosses the railroad shall
not be less than one hundred fifty (150) feet from the line of the
railroad right-of-way.
[R.O. 2013 §410.080(A); CC 1991 §405.080; CC §43.220]
The minimum width of a minor street shall be sixty (60) feet.
Where streets adjoin unsubdivided property, a half street at least
thirty (30) feet in width shall be dedicated and whenever subdivided
property adjoins a half street, the remainder of the street shall
be dedicated. No homes shall be constructed on half streets.
[R.O. 2013 §410.090; CC 1991 §405.100; CC §43.230]
A. Except
in cases where unusual topographic conditions may make it advisable
to modify these provisions, the following shall apply:
1. Maximum length of five hundred (500) feet.
2. Vehicular turnaround at the closed end of a street having a minimum
radius of fifty (50) feet and a roadway having a minimum radius of
forty (40) feet to the interior curb line.
3. In the case of temporarily dead-end streets, which are stub streets
designed to provide future connection with unsubdivided areas adjoining,
the City Planning Commission may require a temporary easement for
a turnaround of the nature indicated above, or an appropriate area
for a backaround, or a roadway at least twenty-six (26) feet in width
of not excessive length to connect the temporary dead end with an
existing street.
[R.O. 2013 §410.100; CC 1991 §405.110; CC §43.235]
A. Streets
shall be so arranged that grades shall not exceed ten percent (10%)
for major thoroughfares and fifteen percent (15%) for minor streets.
The City Planning Commission may permit variation from these grades
where it deems modification advisable to adjust to topographic situations.
B. Gutter
grades on paved gutters shall not be less than one-half of one percent
(.5%).
C. All
changes in street grades shall be connected by a vertical curve of
reasonable length to assure adequate visibility.
D. In
approaching intersections, there should be a suitable leveling of
the street at a grade generally not exceeding five percent (5%) and
for a distance of generally not less than one hundred (100) feet from
the nearest line of the intersecting street. The grade within the
intersection should be as level as possible permitting proper drainage.
[R.O. 2013 §410.110; CC 1991 §405.120; CC §43.240]
A. Street
intersections shall be rounded by radii of at least twelve (12) feet.
B. Streets
should be laid out to intersect at right angles and may be curved
approaching the intersection in order to bring this about; no street
shall intersect any other street at an angle of less than sixty degrees
(60°).
C. The
design of the intersection should be such that a clear sight distance
will be maintained for seventy-five (75) feet at the roadway centerline
with no obstruction to sight within the triangle formed by these points.
[R.O. 2013 §410.120; CC 1991 §405.130; CC §43.245]
Streets that are obviously in alignment with others already
existing and named shall bear the name of the existing streets. The
proposed names of new streets shall be shown on the final plat and
such names shall not duplicate or sound similar to existing street
names. The City Engineer shall determine street names and house numbers.
[R.O. 2013 §410.130; CC 1991 §405.140; CC §43.250]
A. No
block shall be longer than one thousand two hundred (1,200) feet between
street lines. An easement near the center of the block not less than
ten (10) feet wide for a crosswalk may be required on blocks that
are over seven hundred fifty (750) feet in length.
B. The
width of blocks, except for special reasons, shall not be less than
two hundred (200) feet and not more than three hundred fifty (350)
feet.
[R.O. 2013 §410.140; CC 1991 §405.150; CC §43.255]
A. The
lot arrangement and design shall be such that all lots will provide
satisfactory building sites properly related to topography and the
character of surrounding development.
B. The
width and area of all lots shall comply with the requirements of the
zoning district in which they are located. Unless otherwise determined
by zoning regulations, no residential lot shall be less than eighty
(80) feet in width at the building line, or less than one hundred
twenty (120) feet in depth, or less than nine thousand six hundred
(9,600) square feet in area.
C. The
foregoing requirements apply only to residential lots served by public
sanitary sewers. In the case of lots not so served, such lots shall
be of sufficient additional area to properly accommodate a suitable
private sewage disposal device. The City Planning Commission will
determine the required lot size upon report of appropriate tests and
adequate determination and recommendation of the County Health Officer
or State Board of Health.
D. Corner
lots shall have extra width sufficient to permit the establishment
of front building lines on both adjoining streets.
E. In
all lots, so far as possible, the side lines shall be at right angles
to straight street lines or radial to curbed street lines, except
where a variation of this rule will provide a better street and lot
layout.
F. Double
frontage and reverse frontage lots shall be avoided except where their
use will produce definite advantages in meeting special situations
in relation to topography, sound site planning and proper land use.
[R.O. 2013 §410.150; CC 1991 §405.160; CC §43.260]
Building lines conforming with zoning regulations shall be shown
on all lots within the platted area. The minimum building line permitted
for residential lots shall be thirty (30) feet. Provisions shall be
made by the owner's declaration of plat requiring all enclosed parts
of buildings to be set back to such building lines.
[R.O. 2013 §410.160; CC 1991 §405.170; CC §43.265]
Whenever a subdivision is developed as a modern neighborhood or community unit, wherein adequate park area is provided and through traffic is adequately cared for and the majority of the minor streets are of the cul-de-sac type, the Commission may vary the requirements of Sections
410.080,
410.090,
410.130,
410.140 and
410.150 of this Article in order to allow the subdivider more freedom in the arrangements of the streets and lots, but at the same time protect the convenience, health and safety of the probable future residents of the subdivision as well as the general welfare of the surrounding area.
[R.O. 2013 §410.170; CC 1991 §405.180; CC §43.270]
The City Planning Commission and Board of Aldermen may require
that certain minimum regulations regarding type and character of development
be incorporated in the owner's declaration of plat. Such regulations
shall be intended to protect the character and development of the
platted subdivision as well as that of the surrounding development.
[R.O. 2013 §410.180; CC 1991 §405.190; CC §43.275]
Where alleys are not provided in the plat, easements of not
less than five (5) feet in width shall be granted to the City by the
owner on each side of all rear lot lines and, where necessary, side
lot lines for public utility requirements. Easements of greater width
may be required along lot lines or across lots when necessary for
the extensions of main sewers or other utilities. No buildings or
structures will be permitted on easements without authorization of
the Board of Aldermen.
[R.O. 2013 §410.190; CC 1991 §405.200; CC §43.280]
Wherever any stream or surface watercourse is located in an
area that is being subdivided, the subdivider shall at his/her own
expense make adequate provisions for the proper drainage of surface
water and shall also provide and dedicate to the City of Tarkio an
easement along said streams and watercourses meeting the approval
of the City Planning Commission.
[R.O. 2013 §410.200; CC 1991 §405.210; CC §43.285]
Monuments shall be placed at block corners, points of curves,
change in direction along lot lines and at each lot corner in accordance
with specifications of the City Engineer.
[R.O. 2013 §410.210; CC 1991 §405.220; CC §43.290]
Where an area being subdivided includes lands proposed to be
used for parks or schools, the subdivider shall indicate the location
of such areas on the subdivision plat. Park sites are to be purchased
within one (1) year of the recording date of the subdivision by the
City at the appraised raw land value prior to subdivision plus one-half
(½) of the cost of grading and paving, including curbs, of
the portion of any streets that are contiguous to the site. School
sites are to be reserved for two (2) years giving the appropriate
school district the right to purchase the land at the appraised raw
land value prior to subdivision plus one-half (½) the cost
of grading and paving, including curbs, of any streets contiguous
to the site. Should the park or school sites not be purchased within
the time limit specified above, the subdivider may then sell them
for an alternate purpose as shown on the approved subdivision plat.
