§ 50-98. Survey accuracy.

The village engineer/DPW director shall examine all final plats within the village and may make, or cause to be made by a registered land surveyor under the supervision or direction of the village engineer/DPW director, field checks for the accuracy and closure of survey, proper type and location of monuments and liability and completeness of the drawing. In addition:

(1)

The maximum error of closure before adjustment of the survey of the exterior boundary of the subdivision shall not exceed, in horizontal distance or position, the ratio of one part in 10,000; nor, in azimuth, four seconds of arc per interior angle. If filed measurements exceed this maximum, new field measurements shall be made until a satisfactory closure is obtained. When a satisfactory closure of the field measurements has been obtained, the survey of the exterior boundary shall be adjusted to form a closed geometric figure.

(2)

All street, block and lot dimensions shall be computed as closed geometric figures based upon the control provided by the closed exterior boundary survey. If field checks disclose an error for any interior line of the plat greater than the ratio of one part in 5,000, or an error in measured angle greater than one minute of arc for any angle where the shorter side forming the angle is 300 feet or longer, necessary corrections shall be made. Where the shorter side of a measured angle is less than 300 feet in length, the error shall not exceed the value of one minute multiplied by the quotient of 300 divided by the length of the shorter side; however, such error shall not in any case exceed five minutes of arc.

(3)

The village board shall receive the results of the village engineer/DPW director's examination prior to approving the final plat. The village engineer/DPW director may, however, in accordance with section 50-15(b)(4) of this chapter, waive the placing of monuments for a reasonable time, not to exceed one year, on the condition that the subdivider provide a letter of credit, certified check or surety bond equal to the estimated cost of installing the monuments, to ensure the placing of such monuments within the time required by statute. In that case, the village engineer/DPW director's examination required under this section and any related field checks shall be made after the required monuments have been installed. The letter of credit, certified check or surety bond concerned shall not be released until the village engineer/DPW director is satisfied with the accuracy of the land surveying concerned.
