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.

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.

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 — 3, 9-13-2004]

2. 
The City of St. Robert plan review is only for general conformance with the Design Criteria delineated in the Infrastructure Development Regulations and other applicable City Codes. The City is not responsible for the accuracy and adequacy of the design or dimensions and elevations that shall be confirmed and correlated at the job site. The City of St. Robert through approval of this document assumes no responsibility other than that as stated above for the completeness and/or accuracy of this document.
