A. Conformance To Requirements: All survey work for public and private developments within the city shall conform to the requirements described in the following publications and any subsequent additions thereto:
1. "Standard Specifications For Geodetic Control Networks", federal geodetic control committee, September 1984.
2. "Geodetic Bench Marks", U.S. department of commerce, NOAA manual NOS NGS 1, September 1978.
B. Vertical Control: The vertical survey control for all development engineering plans shall be directly tied into at least two (2) established Kane County, IDOT, or city of Batavia bench marks that are referenced to the North American vertical datum of 1929 (NAVD 29), and shall be to a second order, class II level of vertical accuracy. For projects that involve floodplain/floodway issues, the vertical survey shall also reference at least one established FEMA bench mark provided on the appropriate currently effective flood insurance rate map. Topographic contour intervals shall be one foot (1') unless otherwise approved by the city engineer.
C. Horizontal Control: The horizontal survey control for all development engineering plans shall be tied into at least one of the established Kane County or IDOT second order survey control monuments listed below. These monuments are referenced to the North American datum of 1983 (NAD 83).
1. IL KANE 18 39 8 | Kane County monument located at Fabyan Parkway and Kaneville Road | |
2. IL KANE 32 39 8 | Kane County monument located at Mooseheart Road and Randall Road | |
3. IL KANE 25 39 8 | Kane County monument located at Kirk Road and Wind Energy Pass | |
4. KAN25-1B | IDOT monument located at Fabyan Parkway and North Raddant Road |
D. Other Monuments; Approval: When approved by the city engineer, other survey monuments may be used for horizontal and vertical control provided that it can be demonstrated that these monuments have been tied into the Kane County and/or IDOT monuments described above with second order, class I level of horizontal accuracy and a second order, class II level of vertical accuracy as defined in the reference in subsection A1 of this section.
E. Survey Monumentation: A permanent survey monument will be required to be installed within any development or redevelopment project three (3) acres or larger. The city will require the owner/developer of such a development or redevelopment project to make a direct payment to the city for installing the survey monument in lieu of the owner/developer performing this work. Development or redevelopment sites less than three (3) acres will be charged a prorated cost for survey monumentation.
The city will contract with a professional land surveyor, licensed in the state of Illinois, on an annual basis to install all required survey monuments. The monument shall be a class A rod mark constructed to the standards referenced in subsection A2 of this section with a second order, class I level of horizontal accuracy and a second order, class II level of vertical accuracy as defined in subsection A1 of this section. The monument cap shall be engraved to state that it is a city of Batavia survey monument. The city engineer will determine a per acre cost for establishing survey monuments. This cost will be revised annually based on the current cost of performing such work.
F. Record Survey Drawings: After completion of all construction and before the final inspection for acceptance of the public improvements by the city council, and/or the issuance of a certificate of occupancy, and within six (6) months of substantial completion, a full size set of record survey drawings or "as builts" shall be submitted to the engineering department for review and approval. The record drawings shall consist of the approved final engineering plans appended with information to show any field changes, change orders, and additions made during construction. All corrections or changes shall be noted on the plan sheets. No original information shown on the approved engineering plans should be removed from the record survey plan sheets. All constructed site dimensions, elevations, and locations for storm sewers, sanitary sewers, water mains, utility services, all utility lines plugged, capped, or abandoned, pavements, grading, stormwater detention/retention facilities, changes in material, and all other site work shall be surveyed, verified and certified by a professional land surveyor or professional engineer licensed in the state of Illinois. The engineer that sealed the approved final engineering drawings shall also certify the record survey drawings. All constructed dimensions and GIS data shall be at the same level of detail and accuracy as the approved final engineering plans.
All as built numerical values and material names shall be shown adjacent to the plan value or name and circled. A single light line shall be struck through the plan value or name such that it is still legible. A leader shall point from the actual as built item to the circled change if further clarification is needed.
Once the engineering department has accepted the record survey drawings with any subsequent additions and/or corrections made thereto, the owner/developer shall provide the city with one mylar copy of the drawing and a digital version of the same in a format compatible with the current city software standards.
Upon acceptance of the record survey drawings by the city engineer, the as built deposit fee shall be refunded if it complies with the conditions as noted and as required by subsection 11-2-4E of this title. (Ord. 16-04, 2-15-2016)
