§ 66-172. Final plat requirements.

(a)

Generally. A final plat prepared by a registered land surveyor shall be required for all subdivisions. It shall comply in all respects with the requirements of Wis. Stats. § 236.20 and this chapter.

(b)

Additional information. The final plat shall show correctly on its face, in addition to the information required by Wis. Stats. § 236.20, the following:

(1)

Exact length and bearing of the centerline of all streets.

(2)

Exact street width along the line of any obliquely intersecting street.

(3)

Exact location and description of street lighting and lighting utility easements.

(4)

Railroad rights-of-way within and abutting the plat.

(5)

All lands reserved for future public acquisition or reserved for the common use of property owners within the plat.

(6)

Special restrictions required by the common council, upon the recommendation of the plan commission, relating to access control along public ways or to the provision of planting strips.

(7)

Taxes: Certifications by attached information showing that all taxes and special assessments currently due on the property to be subdivided have been paid in full.

(8)

Drainage flows: The subdivider shall cause to be set upon the master grading plan arrows indicating the directions of drainage flows for each property line not fronting on a street on all parcels and along each street as will result from the grading of the site, the construction of the required public improvements, or which are existing drainage flows and will remain. The arrows indicating the directions of flows shall be appropriately weighted to differentiate between the minor and major (100-year event) drainage components. A note shall be added to the plat, and included in a deed restriction, that prohibits alterations of the finished grade from shown on the master grading plan within five feet of any property line. The arrows shall be accompanied on the master grading plan with the following note:

Arrows indicate the direction of drainage flows in various components resulting from site grading and the construction of required public improvements. The drainage flow components located in easements shall be maintained and preserved by the property owner unless approved by the common council designee.

(9)

Groundwater presence: Where the groundwater table is equal to or less than nine feet from the proposed street centerline elevation, the subdivider shall place the following note on the plat:

Subsoil information indicates the presence of groundwater conditions that may require basement elevations on Lot(s) ____________ . On these lots, either basement elevations must be elevated above the groundwater level or the basement exteriors must be fully waterproofed. Prior to construction, a foundation plan shall be submitted to the building inspector for approval.

(10)

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.

(11)

A numbered identification system for all lots and blocks.

(12)

Deed restrictions: Restrictive covenants and deed registrations for the proposed subdivision shall be filed with the final plat.

(13)

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.

(14)

Street dedication: Public rights-of-way for streets and other public areas shall be dedicated to the city with final plat approval. Such dedications shall require the owner's certificate and the mortgagee's certificate in substantially the same form as required by Wis. Stats. § 236.21(2)(a).

(c)

Survey accuracy.

(1)

Examination. The common council and plan commission, or their designees, shall examine all final plats within the city 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. 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 one part in 5,000, 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)

Street, block and lot dimensions. 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 one part in 3,000, 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)

Plat location. Where the plat is located within a quarter section, the corners of which have been relocated, monumented and coordinated by the city, the tie required by Wis. Stats. § 236.20(3)(b), may be expressed in terms of grid bearing and distance; and the material and 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.

(d)

Surveying and monumenting. All final plats shall meet all the surveying and monumenting requirements of Wis. Stats. § 236.15.

(e)

Washburn County Coordinate System. Where the plat is located within a quarter section, the corners of which have been relocated, monumented and coordinated by the city, 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 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 Washburn County Coordinate System.

(f)

Certificates. All final plats shall provide all the certificates required by Wis. Stats. § 236.21, and, in addition, the surveyor shall certify that he has fully complied with all the provisions of this chapter.
