A.
For the
purpose of this Chapter, infrastructure improvements shall be designated
as those streets, curbs and gutters, sidewalks, street lights, water
mains, sanitary sewer lines, storm water conveyances, natural gas
lines and any other utility services and appurtenances that are necessary
for the functional development of all residential and non-residential
land uses in the City of St. Robert.
B.
All plans,
project specifications and reports submitted shall be prepared by,
or under the direction of, a professional engineer licensed in the
State of Missouri and shall be reviewed by the City for compliance
with the minimum design requirements as established in these Regulations
and with all other applicable City codes and ordinances.
C.
Attention
is directed to the design engineer that whenever extraordinary or
unusual problems are encountered in conjunction with a proposed project,
additional information and analysis beyond the minimum requirements
of these standards and criteria will be required.
D.
The City
of St. Robert is not responsible for the accuracy and the adequacy
of the design or dimensions and elevations as depicted on the plans
(which shall be confirmed and correlated at the site of the work).
The City of St. Robert, through the approval of the plans and/or report,
assumes no responsibility for the completeness and/or accuracy of
the public improvement plan or report.
E.
All developers
and engineering consultants submitting plans for infrastructure improvement
projects to the City for review are required to follow the procedures
outlined in the following. No infrastructure improvements may be constructed
in the City of St. Robert without the prior approval of the office
of the Director of Public Works.
F.
Private
improvements, if any, shown on public improvement plans, shall be
clearly defined and marked as such. These improvements will not be
maintained by the City of St. Robert and, as such, an appropriate
note shall be included on the drawings.
[Ord. No. 1711 §§1 —
3, 9-13-2004]
A.
Three
(3) complete sets of prints of engineered plans and specifications
shall be submitted to the office of the Director of Public Works for
review. The normal time for review shall be fifteen (15) working days.
In the case of abnormally large sets of prints or of extremely complicated
drawings, a longer time may be required for review.
B.
The project
plans will be routed through appropriate City departments to obtain
a complete review of all facilities that may be affected by the proposed
construction. In each review, comments and necessary revisions will
be noted on the project plans.
C.
Subsequent
to the review of the plans, the design engineer, consultant or his
representative shall be notified by telephone that the submittal is
ready for return.
D.
The design
engineer or consultant will be required to make all necessary corrections
or revisions as noted on the project plans. Upon completion of the
revisions and/or corrections the plans will again be submitted to
the Director of Public Works office for further review. Revised sheets
submitted shall contain a revision block with identifying notations
and date of revisions. All previous project plans must accompany each
resubmittal. If the project plans are not submitted with the revised
drawings, the plans shall be returned to the consultant without action
until such time as they are included with the submittal.
E.
Plans
will not receive final approval until all supplemental easements,
if necessary, have been duly recorded and a copy has been provided
to the City. Additionally and in conjunction with submittal of final
plans, all permits and/or application for permits shall be submitted
to the appropriate agency for approval prior to final approval of
the plans by the Director of Public Works (i.e., Department of Transportation,
Department of Natural Resources, etc.).
F.
The length
of time for final plan approval will normally be within five (5) working
days. Upon notification of final approval of the plans by the Director
of Public Works, the number of sets of plans as specified in the appropriate
Section of these Regulations shall be submitted for signing and distribution.
G.
Public
improvement plans and engineering reports are approved initially for
one (1) year after the date noted on the returned cover sheet. After
one (1) year, the plans or report shall become null and void and must
be resubmitted prior to approval of construction of that project.
Such plans and/or reports shall be resubmitted to the office of the
Director of Public Works in accordance with the foregoing outlined
procedures and requirements.
H.
The design
engineer shall send one (1) set of plans to each of the private and
public utility companies having territorial jurisdiction in the area
of the improvement upon notification that the drawings have been approved.
[Ord. No. 1711 §§1 —

general notes shall be included on all plan submittals for sanitary
sewer improvement projects. These notes are not meant to be all-inclusive
and in certain situations the Director of Public Works may require
the use of additional notes.
