The improvements set forth under this division are to be considered

[Code 1975, § 30-125; Code 1992, § 26-172]

Prior to issuing the certificate of approval on the subdivision
final plat, the City Council must be satisfied that all improvements
required under this division shall be constructed. All improvements
required under this division, except the water distribution system
and that portion of the storm drainage system which does not benefit
the subdivision under consideration, shall be the responsibility of
the subdivider. The subdivider shall select one of the following methods
of guaranteeing improvements; the method selected shall be subject
to approval of the City Council:
(1)
The subdivider shall be required to deposit with the City Clerk cash,
a certified check or a performance bond, whichever the City elects,
running to the City, to ensure completion of the required improvements
within one year from the date of the approval of the final plat. The
amount of such guarantee shall be set by the City Council and shall
be equal to the cost to be borne by the developer based on an estimate
approved by the Director of Public Works. The City Council shall rebate
to the proprietor, as the work progresses, amounts of any cash deposits
equal to the ratio of the work completed to the entire project. Prior
to the acceptance by the City of the completed improvements, a one-year
maintenance bond in an amount set by the City Council shall be posted
by the subdivider. Any engineering, legal or administrative costs
incurred for design and inspection of improvements shall be the responsibility
of the developer; or
(2)
The subdivider shall petition the City to install the improvements
required under this division and finance them through 100% special
assessment bonds with the special assessment levied against the lots
in the subdivision. The assessment levied against each lot within
a subdivision shall be payable over a ten-year period, with the interest
rate as determined by the Charter. Should the assessment method of
financing improvements be used, the subdivider shall make the home
buyer aware, in writing, of all special assessment costs which have
been levied against the lot in question. If this method is selected,
the date that improvements are to be installed shall be determined
by the City Council. Any engineering, legal or administrative costs
incurred for design and inspection of improvements shall be considered
part of the cost of improvements to be installed and shall be assessable
against the lots in the subdivision.
[Code 1975, § 30-127; Code 1992, § 26-174]
All construction plans and specifications for improvements under
this division shall be submitted to the Director of Public Works for
