[R.O. 1994 § 410.230; Ord. No.
94-8 Sub. Reg. Art. 7 § 1, 5-10-1994]
A. The subdivider shall install or provide for the installation of the
following improvements:
1.
Streets.
a.
Streets in subdivisions comprised of lots smaller than three
(3) acres shall be hard surfaced with curb and gutter in conformance
with the engineer's standards and specifications.
b.
Streets in subdivisions comprised of lots larger than three
(3) acres but less than five (5) acres in size shall be hard surfaced
in conformance with the engineer's standards and specifications. Curbs
and gutters shall not be required.
c.
Streets in subdivisions comprised of lots five (5) acres and
larger in size shall have a compacted base and be surfaced with rock
and gravel in conformance with the engineer's standards and specifications.
2.
Water. Where a public water supply is proposed to serve the
subdivisions, said water lines shall be installed in proper easements
or within the limits of the street and alley right-of-way. The system
shall be of equal or better quality and size than the minimum standards
of the City and shall meet all State Department of Natural Resources
(DNR) standards. Where private water supplies are proposed, adequate
provision shall be made for easements to allow installation of a public
system should the property ever be annexed or required to develop
a public supply. Private water systems shall meet all requirements
of the State DNR.
3.
Sewer.
a.
A public sanitary sewer will be used in all subdivisions wherever
possible. The sewer shall be designed and constructed to provide service
to each lot within the subdivision. The system of lateral sewers shall
collect the sewage within the subdivision and discharge it into the
City sewer system. All subdivisions which connect to the City sewer
systems shall be required to be annexed into the City. Upon determination
of the City that the City sewer system is not practicably available
to the development, the subdivider may submit plans for consideration
for disposal of sewage into a central, public treatment facility or
a private system. The sewer system shall be of equal or better quality
and size than the minimum standards of the City as determined by the
City Engineer. The sewer system shall meet all State DNR standards.
b.
In subdivisions where individual private wastewater systems
are proposed, adequate provision shall be made for easements to allow
the installation of a public system should the property ever be annexed
or required to develop a public system.
4.
Walks. Sidewalks shall be installed on both sides of all arterial
and collector streets and on both sides of the street in a commercial
district. All sidewalks shall be not less than four (4) feet in width
of Portland cement concrete and shall comply with the specifications
of the Governing Body. Walks shall also be installed in any pedestrian
easements as may be required by the Planning and Zoning Commission.
Installation of sidewalks may be delayed for one (1) side of a block
between two (2) intersecting streets until seventy-five percent (75%)
of the lots on that side of the block have been developed or within
three (3) years of the approval of the final plat, whichever comes
first.
5.
Storm Drainage. The subdivider shall install culverts, storm
sewers, rip-rap slopes, stabilized ditches, stormwater detention facilities
and other improvements necessary to adequately handle stormwater.
All improvements shall comply with the minimum standards of the City
and shall be approved by the City Engineer prior to construction.
a.
Where developments are determined by the City Engineer to be
in close proximity to unimproved stream channels, an engineering study
shall be required to determine the stability of the stream banks.
The study shall evaluate the likelihood that normal stream bank slippage,
failure and erosion will endanger structures proposed as a part of
the development or the yards of residential lots. Such studies shall
analyze the impact of full upstream development as shown on the City's
Comprehensive Plan map and include a complete identification and analysis
of the soil profile and underlying bedrock upon which the development
is to take place. Based on this analysis, engineering plans shall
be submitted showing the structural measures to be used to stabilize
those banks which are determined to be unstable. The study shall be
submitted concurrent with the application for final plat approval
and shall be reviewed and approved by the City Engineer prior to recording
the plat. Storm drainage easements may be required where necessary
to allow ongoing maintenance of the stream channel and any stabilization
measures.
b.
The City shall pay for the installation of all storm sewer curb
inlets, manholes and pipes required for the development of subdivisions.
c.
Detention basins or ponds, paved drainage ditches and other
items determined by the Planning and Zoning Commission and Board of
Aldermen to be an unusual or excessive requirement for development
of the property shall be installed at the developer's expense.
6.
Street Signs. The City shall install street signs at all intersections
within a subdivision.
7.
Street Trees. Street trees should be planted in accordance with
proper landscape design standards and site plan review requirements.
8.
Permanent Monuments. Permanent monuments shall be placed at
all lot and block corners, angle points, point of curve in streets
and at intermediate points as required prior to the final acceptance
of the plat by the City. Said permanent monuments shall be one-half
(1/2) inch minimum iron bars or pipe, eighteen (18) inches long, shall
be set with top of monument flush with existing ground line and shall
include an identification cap on the bar.
9.
Street Lights. The City shall provide for the installation of
street lights at street intersections and other locations as it determines
necessary. The developer shall be responsible for all costs for providing
street lighting equipment other than that determined as necessary
by the City.
[R.O. 1994 § 410.240; Ord. No.
94-8 Sub. Reg. Art. 7 § 2, 5-10-1994]
A. Where the proposed subdivision is a resubdivision or concerns an
area presently having any or all required improvements as previously
set out and where such improvements meet the requirements of this
Article and are in good condition as determined by the Governing Body
upon its consideration of the opinion of the City Engineer, no further
provision need be made by the subdivider to duplicate such improvements.
However, where such existing improvements do not meet said requirements
as determined by the Governing Body upon its consideration of the
opinion of the City Engineer, the subdivider shall provide for the
repair, correction or replacement of such improvements so that all
final improvements will then meet said requirements as determined
by the Governing Body upon its consideration of the opinion of the
City Engineer.
B. Where the proposed subdivision is a resubdivision or concerns an
area presently abutting or continuing any existing public street of
less than the minimum required right-of-way width or roadway width,
land shall be dedicated so as to provide a minimum street right-of-way
width established by these regulations and/or by the policy of the
Governing Body; and the subdivider of such proposed subdivision shall
provide an additional roadway pavement meeting the minimum standards
set by these regulations and the Governing Body. The Governing Body
shall determine what adjustment to make where the aforesaid widening
merges with existing streets which are of smaller width at the boundary
of such proposed subdivision. The Governing Body may reduce the minimum
roadway system in the proposed subdivision if the extension of such
roadway is already improved at each end of such roadway in the subdivision
and the roadway in the proposed subdivision is two (2) blocks or less
in length.
