sewer system if feasible and approved by City Council. Where lots
cannot be connected with a public sewer system, provisions must be
made for sanitary sewerage, consisting of a central treatment plant
or individual disposal devices for each lot. On lots where individual
septic tanks are to be utilized, lots shall not be less than 0.5 acre

[Amended 4-16-1987 by Ord. No. 75-52]
A. The subdivider of a subdivision within the City limits shall provide
park and recreational facilities or an optional fee in lieu of land
dedication.
(1) Before any subdivider shall receive final plat approval for a subdivision
within the City limits, said subdivider shall dedicate to the City
a portion of such land suitable for the purpose of park and recreational
facilities for the future residents of the subdivision. Such land
may be outside the boundaries of the subdivision, but shall be within
one mile of the subdivision taken in a straight line from one of the
exterior boundaries of the subdivision as shown by the plat of the
subdivision.
(2) At the option of the City, the subdivider may pay a fee to the City
in lieu of land dedication for a park and recreational facility for
use by the future residents of the subdivision.
(3) After a plat with an area proposed for park dedication has been given
preliminary approval by the Planning and Zoning Commission, it shall
be the responsibility of the developer to draft a preliminary plan
and calculate the development costs for the park area. The developer
shall assume all costs associated with the development of the dedicated
park. The plan and estimated costs shall be submitted to the Planning
and Zoning Commission for consideration at the time of their final
approval for the subdivision.
B. Amount of land to be dedicated; use of land dedicated.
(1) Land shall be dedicated in the amount of 2.5 acres per 1,000 persons.
Population of the subdivision shall be calculated at the average of
3.3 persons per dwelling unit within the subdivision.
(2) The minimum size acceptable to the City for a park site shall be
12,000 square feet. A fee in lieu of land dedication may be paid,
if the area required to be dedicated is less than 12,000 square feet.
If the entire area to be subdivided houses 25 persons or less, a park
fee, but no land dedication, shall be required. Land to be dedicated
shall be platted in such a way that the land may be used for building
purposes at some future date.
(3) The amount of land to be dedicated shall be prorated on fractional
units of household residents, i.e., 500 persons = 1.25 acres; 100
persons = 0.25 acre.
(4) Land received by the City pursuant to this section shall be used
for the purpose of providing park and recreational facilities to serve
the subdivision for which received.
(5) All improvements, including handicap provisions which front on the
park acreage such as curb, gutter and paving, shall be provided by
the subdivider.
(6) Properties designated on subdivision plats and zoned for multiple-family
construction of more than four units per lot may have park land dedication
requirements waived if developers provide covenants on the deeds that
all multifamily units constructed in these areas shall include the
provisions of recreation facilities which will be maintained by multifamily
unit owners to serve residents of the multifamily units.
C. Amount of fee in lieu of land dedication and limitations on use of
fees.
(1) If the subdivider pays a fee in lieu of land dedication, the amount
of the fee shall be based upon the number of new dwelling units created
at a rate of $78 per single-family residence, townhouse or mobile
home and a rate of $39 per apartment unit.
(2) The fees received under this section shall be placed in a separate
public park recreational purchase and improvement account, and shall
be used by the City only for acquisition, development and improvement
of park and recreational facilities to serve the subdivision for which
fees have been paid. These facilities must be no more than one mile
from the subdivision taken in a straight line from one of the exterior
boundaries of the subdivision as shown by the plat of the subdivision.
