A. 
General. A preliminary plat shall be required for all subdivisions and shall be based upon a survey by a professional land surveyor and the plat prepared on Mylar or paper of good quality at a scale of not more than 100 feet to the inch and shall show correctly on its face the following information:[1]
(1) 
Title under which the proposed subdivision is to be recorded, which name shall not duplicate or be alike in pronunciation of the name of any plat heretofore recorded in the Village unless considered an addition to the subdivision.
(2) 
Legal description/location of the proposed subdivision by government lot, quarter section, township, range, county and state.
(3) 
Date, scale and North arrow.
(4) 
Names, telephone numbers and addresses of the owner, engineer, subdivider, land surveyor preparing the plat, and any agent having control of the land.
(5) 
Entire area contiguous to the proposed plat owned or controlled by the subdivider may be required by the Plan Commission to be included on the preliminary plat even though only a portion of said area is proposed for immediate development. Where a subdivider owns or controls adjacent lands in addition to those proposed for development at that time, the subdivider shall submit a concept plan for the development of the adjacent lands showing streets, utilities, zoning districts and other information as may affect the review of the preliminary plat in question. The Village Engineer may waive these requirements where adjacent development patterns have already been established.

[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
B. 
Additional information. The final plat shall show correctly on its face, or on a supporting document, in addition to the information required by § 236.20, Wis. Stats., the following:
(1) 
Exact street width along the line of any obliquely intersecting street.
(2)

(7) 
Locations where the groundwater table is equal to or less than nine feet from the proposed street center-line elevation; the subdivider shall place the following note on the plat: "Subsoil information indicates the presence of high groundwater conditions on Lot(s) _________. On these lots, either basement elevations must be elevated above the groundwater level or the basement exteriors must be fully waterproofed."
(8) 
Dimensions of lot lines shall be shown in feet and hundredths; no ditto marks shall be permitted. When lot lines are not at right angles to the street right-of-way line, the width of the lot shall be indicated at the building setback line in addition to the width of the lot at the street right-of-way line.

D. 
Property owners' association. The legal instruments creating a property owners' association for the ownership and/or maintenance of common lands in the subdivision shall be filed with the final plat.
E. 
Street dedication. Public rights-of-way for streets and other public areas shall be dedicated to the Village with final plat approval. Such dedications shall require the owner's certificate and the mortgagee certificate in substantially the same form as required by § 236.21(2)(a), Wis. Stats.
F. 
Survey accuracy.
(1) 
The Village Board and Plan Commission, or their designees, shall examine all final plats within the Village of East Troy and may check for the accuracy and closure of the survey, the proper kind and location of monuments, and legibility and completeness of the drawing.
(2) 
Maximum error of closure before adjustment of the survey of the exterior boundaries of the subdivision shall not exceed, in horizontal distance or position, the ratio of 1:10,000 nor, in azimuth, four seconds of arc per interior angle. If field measurements exceed this maximum, new field measurements shall be made until 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.
(3) 
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 checks disclose an error for any interior line of the plat greater than the ratio of 1:5,000, 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.
(4) 
Where the plat is located within a quarter section, the corners of which have been relocated, monumented, and coordinated by the Village, the tie required by § 236.20(3)(b), Wis. Stats., may be expressed in terms of grid bearing and distance, and the material and Wisconsin state plane coordinates of the monument marking the relocated section or quarter corner to which the plat is tied shall be indicated on the plat. The grid bearing and distance of the tie shall be determined by a closed survey meeting the error of closure herein specified for the survey of the exterior boundaries of the subdivision.
G. 
Surveying and monumenting. All final plats shall meet all the surveying and monumenting requirements of § 236.15, Wis. Stats.
H. 
State plane coordinate system. Where the plat is located within a quarter section, the corners of which have been relocated, monumented and coordinated by the Village, the plat shall be tied directly to one of the section or quarter corners so relocated, monumented and coordinated. The exact grid bearing and distance of such tie shall be determined by field measurements, and the material and Wisconsin state plane coordinates of the monument marking the relocated section or quarter corner to which the plat is tied shall be indicated on the plat. All distances and bearings shall be referenced to the Wisconsin Coordinate System, South Zone, and adjusted to the Village's control survey.
I. 
Certificates. All final plats shall provide all the certificates required by § 236.21, Wis. Stats. In addition, the surveyor shall certify that he/she has fully complied with all provisions of this chapter.
A. 
Certified survey requirements. A certified survey map prepared by a professional land surveyor shall be required for all minor subdivisions. It shall comply in all respects with the requirements of § 236.34, Wis. Stats.[1]

C. 
State plane coordinate system. Where the map is located within a quarter section, the corners of which have been relocated, monumented, and coordinated by the Village, the map shall be tied directly to one of the section or quarter corners so relocated, monumented and coordinated. The exact grid bearing and distance of such tie shall be determined by field measurements, and the material and Wisconsin state plane coordinates of the monument marking the relocated section or quarter corner to which the map is tied shall be indicated on the map. All distances and bearings shall be referenced to the Wisconsin Coordinate System, South Zone, and adjusted to the Village's control survey.
D. 
Certificates. The surveyor shall certify on the face of the certified survey map that he/she has fully complied with all the provisions of this chapter. The Village Board, after a recommendation by the reviewing agencies, shall certify its approval on the face of the map.
E. 
Street dedication. Dedication of streets and other public areas shall require, in addition, the owner's certificate and the mortgagee's certificate in substantially the same form as required by § 236.21(2)(a), Wis. Stats.
F. 
Requirements. To the extent reasonably practicable, the certified survey shall comply with the provisions of this chapter relating to general requirements, design standards and required improvements. Conveyance by metes and bounds shall be prohibited where the lot(s) involved is less than 1 1/2 acres or 300 feet in width.
