A. General construction plans. General construction plans shall be prepared for all required improvements. Plans shall be drawn at a scale of no more than 1 inch equals 100 feet, and map sheets shall be of the same size as the primary plat. The following shall be shown:
1. Profiles showing existing and proposed elevation lines of all streets. Where a proposed street intersects an existing street or streets, the elevation along the center line of the existing street or streets, within 100 feet of the intersection, shall be shown. Radii of all curves, lengths of tangents, and central angles on all streets.
2. The Commission may require a topography map where steep slopes exist, that cross-sections of all proposed streets at 100-foot stations and shown at five points as follows: on a line at right angles to the center line of the street, and all elevation points shall be at the center line of the street, each property line, and points 25 feet inside each property line.
3. Plans and profiles showing the locations and typical cross-section of street pavements including curbs and gutters, sidewalks, drainage easements, servitude, right-of-way, manholes, and catch basins, the locations of street trees, street lighting standards, and street signs; the location, size, and invert elevations of existing and proposed sanitary sewers, storm water drains, and fire hydrants, showing connection to any existing or proposed utility systems; and exact location and size of all water lines, gas lines or other underground structures. Letters of approval shall be obtained from the City Board of Public Works and Safety and the County Engineer stating that plan is acceptable or conditions stated to make it so.
4. Location, size elevation, and other appropriate description of any existing facilities or utilities, including, but not limited to, existing streets, sewers, drains, water mains, easements, water bodies, streams, flood plains, and other pertinent features such as swamps, railroads, buildings, features noted on the Official Map or Comprehensive Plan at the point of connection to proposed facilities and utilities within the subdivision, and measured four feet above ground level; and which the Plan Commission has required to be reserved, the water elevations of adjoining lakes or streams at the date of the survey, and the approximate high-and low water elevations of such lakes or streams; all elevations shall be referred to the United States Geodetic Survey (USGS) datum plane. If the subdivision borders a lake, river, or stream, the distances and bearings of a meander line established not less than 20 feet back from the ordinary high-water mark of such waterways shall be shown.
5. Topography at the same scale as the primary plat with a contour interval of two feet, referred to the sea-level datum; all data provided shall be the latest applicable USGS data and should be so noted on the plat.
6. All specifications and references required by the (city) (county's) construction standards and specifications, including a site-grading plan for the entire subdivision.
7. Title, name, address, signature, registration number and seal of the professional engineer and/or surveyor, and date, including revision dates.
B. Requirements for approval. The applicant shall file three sets of detailed drawings and specifications with the Planning Commission before starting any improvements. Four or five sets may be necessary if a Drainage Board is involved; or a County Engineer, when a subdivision is located in the jurisdiction of the county but city water and/or sewer treatment facilities are used.
C. Review process. The Executive Director of the Planning Department shall immediately refer these plans to the appropriate agencies of the affected participating jurisdictions for review. These agencies shall give written approval or denial, with justification for their action. In no event shall secondary approval of the final plat be given prior to the approval by the Board of Public Works and Safety of the constructions plans.
D. Installation of improvements. The installation of improvements shall be inspected by the appropriate participating jurisdictions. Said inspections are required in all instances regardless of whether the work is performed before or after secondary (final) approval is given. Failure to request or procure inspection of work performed after the date of this ordinance, and before secondary approval is given, may be cause for denial or rescinding secondary approval.
