All improvements shall be designed and installed in accordance
with all of the elements of the General Plan and shall meet the minimum
standards established by the ordinances and regulations relating thereto.
Plans for the improvements herein required shall be prepared
by the City Engineering Department or by a qualified engineer, registered
in the State of Oklahoma. Two sets of prints of the proposed plans
and specifications for all improvements shall be filed with the Planning
Commission at the time of submission of the final plat. One set of
"as built" plans and specifications certified and signed by an engineer
registered in the State of Oklahoma shall be filed with the City Clerk
prior to the acceptance by the City Commission of any improvements
installed by the subdivider.
In lieu of completion of the improvements herein required, the
City Commission may require the subdivider to file a surety bond to
insure the actual construction of such improvements according to the
plans and specifications filed with the Planning Commission within
a period of time not to exceed two years from the date of approval
of the final plat. Such bond shall be in the amount of 100% of the
estimated cost of the improvement as determined by the Planning Commission
and with surety and conditions satisfactory to the City Commission.
In any case where the City Commission does not require a bond
for the improvements required herein, no building shall be permitted
on any lot or in any area in a subdivision where the proposed construction
will produce runoff or require utility services that affect other
areas or lots located within or outside the City limits until a surety
bond is posted to cover the estimated cost for the portion of the
drainage or utility improvements that will be needed to protect the
affected area.
Each lot and block corner shall be marked with iron pipes or
pins not less than 1/2 inch in diameter and not less than 18 inches
long set not less than one inch below the finished grade. Each subdivision
corner shall be marked with a permanent concrete marker capped with
a noncorrosive metal plate set not less than one inch below the finished
grade.
The subdivider of any subdivision to be used for residential,
commercial, industrial or other purposes shall lay out, grade and
otherwise improve all street that are designated on the approved plat
or that directly serve the subdivision in accordance with the specifications
of the City or the county except where the governing bodies have policies
of additional assistance to the owners or developers and in accordance
with the following provisions:
1. The new design of an improvement of an intersection of any new street
with an existing state or federal highway shall be in accordance with
the specifications of the Oklahoma State Highway Department, but in
no case shall the standard be less than the applicable City specifications.
2. Whenever a subdivision contains a major street that requires a street
facility that is more costly than is required to serve the future
occupants of the subdivision, the subdivider shall be required to
pay only the portion of the cost of the major street that would equal
the cost of an improvement required to serve only the subdivision,
as determined by the Planning Commission.
3. All driveways which connect with public street shall be constructed
in accordance with "Standard Design of Driveway Entrances for Oklahoma
Highways", revised August 1960, and subsequent amendments thereto,
as prepared by the Oklahoma State Highway Department.
A plan for a system of sidewalks and walkways shall be prepared
that will provide adequate pedestrian walkways within a residential
or commercial subdivision or portion thereof with consideration given
to sidewalk connections with all of the community facilities and commercial
enterprises located within or adjacent to the subdivision, and in
a manner that will provide convenient pedestrian circulation throughout
the neighborhood or area in which the subdivision is located. The
Planning Commission may require the construction of sidewalks to connect
with existing or future proposed sidewalks in areas adjacent to the
subdivision where such sidewalks are needed for pedestrian circulation.
Sidewalks and walkways where constructed in the subdivision shall
be in accordance with the sidewalk system plan approved by the Planning
Commission and in accordance with the specification governing sidewalk
and walkway construction.
The subdivider shall install water lines and fire hydrants in
accordance with the policies and specifications governing water line
construction except where the governing bodies have policies of additional
assistance to owners or developers.
Drainage shall be provided in accordance with the specifications
contained in the ordinances and regulations relating thereto.
Where the subdivision contains sewers, sewage treatment plants,
water supply systems, or other physical facilities that are necessary
or desirable for the welfare of the area or that are of common use
or benefit and which are not or cannot be satisfactorily maintained
by an existing public agency; provision shall be made which is acceptable
to the agency having jurisdiction over the location and maintenance
of such facilities for the property and continuous operation, maintenance
and supervision of such facilities.
