      (2)   Jurisdiction. The regulations herein governing plats and the subdivision of land shall apply to all areas of the county lying outside the incorporated limits of municipalities with the exception of the area up to two miles of a municipality whereby such municipality, by resolution, has extended the application of such regulations pursuant to M.S. § 462.358, Subdivision 1a, as it may be amended from time to time, and with the exception where a town has adopted subdivision regulations pursuant to M.S. § 368.01, as it may be amended from time to time.
      (3)   Application of ordinance. Any plat, or survey as applicable, hereafter made, for each subdivision or each part thereof lying within the jurisdiction of this ordinance, shall be prepared, presented for approval and recorded as herein prescribed. The regulations contained herein shall apply to the subdivisions of a lot, parcel or tract of land for the purpose of immediate or future transfer of ownership, including the re-subdivision or re-platting of lots or parcels and common interest community lots. A lot, parcel or tract of land, for purposes of this section is a designated area of land described and recorded with the County Recorder as of May 17, 1983.
      (4)   Exemptions. 
         (a)   Subdivision approval shall not be required for those properties that qualify under one or more of the following exemptions:
            1.   Correction of engineering, drafting or surveying errors;
            2.   Combining of two or more lots into a single lot, provided a covenant acceptable to the Zoning Administer is recorded with the County Recorder;
            3.   Subdivision of a parcel of record to increase the size of two or more adjacent substandard parcels of record or to attach a residence to a feedlot owned by the same party, provided that a covenant acceptable to the Zoning Administrator to combine the parcels for purposes of sale and/or development is recorded with the County Recorder, and that a certificate of survey, prepared by a licensed surveyor, accompanies the covenant;
            4.   Adjustment of common boundary lines between adjoining property owners, providing that the adjustment results in no violation of this ordinance and a certificate of survey, prepared by a licensed surveyor, must be submitted to the Planning and Zoning Department and to the County Recorder;
            5.   Partition of lands by will or through action of a court of competent jurisdiction, unless or until development of the land is proposed;
            6.   Where a property has been changed in size or shape by reason of the taking of a part of such property for public use by reference to a properly drawn and recorded plat, such as a right-of-way plat; provided, that the outlines and dimensions of such remainder may be clearly determined by references to the previously recorded plats; and/or
            7.   Subdivisions and property boundary alterations that are the direct result of construction and operation activities of utilities exempted by state statute.
         (b)   All plats lawfully recorded prior to the effective date of this ordinance shall not be subject to the provisions contained herein.
      (5)   Land suitability requirement. No land shall be subdivided which is held unsuitable by the county for the proposed use because of any of the following conditions:

Pursuant to subsection (D) below (plats submission procedure and data), before any plat shall be recorded or be of any validity, it shall be reviewed by the Planning Commission and approved by the Board of County Commissioners as having fulfilled the requirements of this ordinance. Where any municipality has adopted extraterritorial subdivision regulations as provided by the M.S. § 462.358, as it may be amended from time to time, any proposed plat lying within two miles of the municipality shall conform to the procedures as prescribed by the municipality.
      (7)   Compliance. No plat or any subdivision shall be entitled to record in the County Recorder’s office or have any validity until the plat, or survey as applicable, thereof has been prepared, approved and acknowledged in the manner prescribed by this ordinance.
      (8)   Zoning permits. No building permits shall be issued by the county for the construction of any building, structure or improvement to the land or to any lot in the subdivision, as defined herein, until all requirements of this ordinance have been complied with.
      (9)   Limited jurisdiction. This ordinance shall be subject to the rules and regulations governing plats and subdivision of land in areas where a municipality has adopted extra territorial jurisdiction in the county. All applications for plats in areas of the county, which municipalities have by resolution extended subdivision jurisdiction and in towns who have subdivision regulations, shall be made to the regulatory power.
   (B)   Minor and major subdivisions.
      (1)   Minor subdivision.
         (a)   When required. A minor subdivision is required for proposed land divisions that will result in:
            1.   A parcel of land of at least one acre at a density of one unit per quarter-quarter section in the A- Agricultural District or LR- Limited Residential Districts;
            2.   A parcel that is subdivided for a purely agricultural purpose with a covenant approved by the County Planning and Zoning Administrator prohibiting residential use; or
            3.   A parcel or parcels created in the A-1 Agriculture Protection District as a receiving site or sites pursuant to process described in § 6.09, Transfer of Development Right (TDR). The minor subdivision may only be authorized following the recording of an appropriate protective easement or easements on a standing site or sites and only at the densities described in § 6.09, Transfer of Development Right (TDR).
         (b)   Application. The applicant for a minor subdivision shall submit a sketch plan of the proposed new lots the information requirements of this subsection together with an application for a zoning permit meeting the requirements found in § 3.02, Zoning Permits.
            1.   Survey required. For all new lots five acres or smaller the applicant shall file a survey prepared and signed by a licensed land surveyor to the Zoning Administrator of the land to be divided or consolidated.
            2.   Survey exemption. For any minor subdivision that does not include any lots of five acres or smaller the new lots may be recorded with the metes and bounds description.
            3.   Deed history. The applicant shall provide the parcel’s deed history dating back to the first implementation of subdivision regulations (May 17, 1983).
            4.   Drawing. The applicant shall submit any drawing in a Geographic Information System (GIS) electronic format and/or in an AutoCAD format that meets the standards of the Zoning Administrator.
         (c)   Administrative approval of application. After the submission of a completed application and sketch plan, the Zoning Administrator shall review the application and sketch plan.
            1.   Thirty-day review. The Zoning Administrator shall within 30 days, approve with conditions, or disapprove the application and sketch in writing and advise the applicant of any stipulations or conditions that are required in the layout or character of development. The Zoning Administrator may choose to submit the application to other county departments for review; however, such review shall be accommodated within the review period stated above.
               a.   Signed applicant acknowledgment required. The applicant shall certify in writing that he or she agrees to all requirements or conditions as stipulated in the Zoning Administrator’s approval.
               b.   Intended use. All parcels being created for the purpose of residential, commercial or industrial use can comply with all requirements of this article, meet all relevant zoning and development standard requirements for the intended use including minimum dimensions and setbacks, and that the new lot includes frontage on an existing publicly dedicated road or highway.
            2.   Appeal of application review. Within 30 days of receipt of the Zoning Administrator’s action, the applicant may appeal any disapproval or any additional requirements or conditions stipulated in the Zoning Administrator’s approval. The application and sketch plan shall then be forwarded to the Planning Commission for consideration at the next regularly scheduled meeting. For the purpose of reviewing the application and sketch plan, the Planning Commission may hold one or more public hearings. Following review, the Planning Commission shall recommend to the County Board approval, approval with conditions or denial of the application. The County Board, at a regularly scheduled meeting, will then make the final decision.
      (2)   Major subdivision (revised by ordinance amendment 9-16-09). 
         (a)   A major subdivision is required for:
            1.   Proposed land divisions that will result in more than one lot;
            2.   Divisions that would create an increase in residential density greater than provided for within the code; or
            3.   For any division of land for which development of a new public or private street or access serving more than one parcel is required.
         (b)   Major subdivisions must follow the sketch plan, preliminary plat and final plat submittal procedures, plat document requirements, and all other applicable requirements of this ordinance. This section does not apply to parcel splits that are exempted as described herein.
   (C)   Design standards.
      (1)   General. Design standards shall assure that the layout of the subdivision is in harmony with existing adopted plans affecting the development of its surroundings and shall be in harmony with existing development unless the proposed development is part of a larger redevelopment plan.
         (a)   The County Board may designate that unique and irreplaceable natural features which add value to all developments in the county, such as trees or groves, watercourses, beaches, historic spots, vistas and other similar irreplaceable assets shall be preserved within the development.
         (b)   Loop streets and other street designs which minimize the need for cul-de-sacs and maximize access for public safety and county maintenance vehicles shall be encouraged.
      (2)   Blocks.
         (a)   Blocks shall have sufficient width to provide for two tiers of lots of appropriate depths. Exceptions to this prescribed block width shall be permitted in blocks adjacent to major streets, railroads, waterways or lakeshores.
         (b)   The lengths, widths and shapes of blocks shall be such as are appropriate for the locality and the type of development contemplated, block lengths shall normally not exceed 1,320 feet, nor be less than 400 feet in length. Wherever practicable, blocks along major arterials and collector streets shall be not less than 1,000 feet in length. In long blocks, the Planning Commission may require the reservation of an easement through the block to accommodate utilities, drainage facilities or pedestrian traffic. Pedestrian ways or crosswalks, not less than ten feet wide, may be required by the County Board through the center of blocks more than 800 feet long where deemed essential to provide circulation of pedestrian access to playgrounds, transportation, shorelands or other, community facilities. Blocks designed for industrial uses shall be of such length and width as may be determined suitable for the prospective use.
      (3)   Lots.
         (a)   The minimum lot area, lot width and lot depth shall conform to the requirements of the zoning district, except in cases where a lot is dedicated as an outlot (undevelopable), whereby a deed restriction filed with the county shall permanently prohibit building a structure on the lot.
         (b)   No newly created lot shall contain any building used in whole or in part for residential purposes unless such lot abuts for at least 66 feet on at least one street, road or private lane, except 50 feet minimum may be allowed where no further division or parcels or lots can be created, or if fronting on a private lane. Where a lot that meets qualifications of a legal lot of record as of the effective date of this ordinance does not abut a street, road, or private lane, access may be provided to a public road by an exclusive, unobstructed private easement of access with a minimum width of 30 feet.
         (c)   Corner lots for residential use shall have additional width to permit appropriate building setback from both roads as required by the county zoning ordinance.
         (d)   When possible, side lot lines shall be at right angles to straight street lines or radial to curved street lines.
         (e)   Double frontage lots shall be avoided except where backing on a highway or other arterial road, or where topographic or other conditions render other designs unreasonable. Such double frontage lots shall have an additional depth of at least 20 feet in order to allow space for screen planting along the rear lot line.
         (f)   Every lot must have sufficient frontage on a public dedicated road or street other than an alley, provided, that where private roads are permitted such frontage may be on a private street.
         (g)   Lot remnants which are below the minimum lot size must be added to adjacent or surrounding lots rather than be allowed to remain as an unusable outlot or parcel.
          (h)   For major subdivisions, no lot shall have more than six sides and, unless in the A Agricultural District, panhandle lots are prohibited.
      (4)   Roads, highways, streets and alleys.
         (a)   The design of all streets shall be considered in their relation to existing and planned streets, to reasonable circulation of traffic, to topographic conditions, to runoff of stormwater and to the proposed uses of the area to be served.
         (b)   Where new streets extend existing adjoining streets, their projection shall be at the same or greater width, but in no case less than the minimum required width.
         (c)   Within major subdivisions, street stub linkages shall be provided among adjoining existing and proposed subdivisions in order to allow convenient and effective travel among subdivisions.
            1.   Street stub linkages shall be provided at a ratio of at least one linkage street right-of-way per 800 linear feet of subdivision or land development boundary line, which adjoins vacant or undeveloped land, unless determined to be unnecessary by the Planning Commission.
            2.   Street stub linkages shall be planned and constructed to the subdivision or land development boundary line. If the stub is in excess of 100 feet in length, then a temporary paved turn-around area shall be provided.
            3.   When the adjoining land is developed, its street system must connect with and incorporate the previously constructed street stub linkages.
         (d)   Half streets shall be prohibited except where the County Board finds it to be practicable to require the dedication of the other half when the adjoining property is subdivided or when an easement for the other half is dedicated. In such event, access to the half street shall be prohibited until such adjoining property is subdivided.
         (e)   Proposed streets obviously in alignment with existing and named streets shall bear the names of such existing streets. In no case shall the name of the proposed street duplicate names, including phonetically similar names, elsewhere in the county excepting, municipalities.
         (f)   Where a major subdivision is to be located adjacent to a collector road the County Board shall require that lots back onto those thoroughfares and be landscaped to provide a buffer zone. Access to the interior lots shall either be a cul-de-sac or designed as a U-shaped or loop street.
         (g)   The street arrangements shall not be such as to cause hardship to owners of adjoining property in platting their own land and providing convenient access to it.
         (h)   Tangents of at least 100 feet in length shall be introduced between reverse curves on collector streets and 50 feet on lesser streets.
         (i)   Except as linkage street-stubs, dead-end streets shall be prohibited, but cul-de-sacs will only be permitted when, because of topography or other conditions, the subdivider can prove to the satisfaction of the Planning Commission that no reasonable alternative exists. Cul-de-sacs shall not be longer than 500 feet. Turn-arounds shall have a minimum outside roadway diameter of 60 feet and a right-or-way diameter of not less than 70 feet.
         (j)   Local streets are intended for access to abutting property and shall be so aligned that their use by through traffic shall be discouraged*.
         (k)   Insofar as practical, streets shall intersect at right angles and no intersection shall be at an angle of less than 70 degrees. It must be evident that safe and efficient traffic flow is encouraged. No intersection shall contain more than four “corners”. Street jogs with centerline off-sets of less than 125 feet shall be avoided.
         (l)   For all streets rights-of-way hereafter dedicated and accepted, the following minimum right-of-way width and grades shall be met:

         (m)   State Department of Transportation Standards for horizontal and vertical alignment, grades and the like, shall also be complied to meet county and township standards.
         (n)   Private streets or roads may be permitted provide these streets or roads meet the approval of the County Board and standards set forth in this ordinance. No person shall sell any parcel of land in a subdivision if it abuts on a road which has not been accepted as a public road unless the seller informs the purchaser in writing of the fact that the road is not a public road and is not required to be maintained by the town or county.
         (o)   Minor street access to state and federal highways shall not be permitted at intervals of less than 600 feet.
         (p)   Street names shall be determined by the Zoning Administrator.
      (5)   Easements.
         (a)   An easement for utilities at least six feet wide, shall be provided along the side of lots and/or the rear line of lots where necessary to form a continuous right-of-way, at least 12 feet in width. If necessary for the extension or construction of main water or sewer lines or similar utilities, easements of greater width may be required along lot lines or across lots.
         (b)   Utility easements shall connect with easements established in adjoining properties. These easements, when approved, shall not thereafter be changed without the approval of the County Board, after review by the Planning Commission.
         (c)   Additional easements for pole guys should be provided at the outside of turns. Where possible, lot lines shall be arranged to bisect the exterior angle so that pole guys will fall alongside lot lines.
         (d)   Where a subdivision contains or is traversed by a watercourse, drainageway, channel, lake or stream, a stormwater easement, drainage right-of-way or park dedication, whichever the County Board may deem the most appropriate, conforming substantially with the lines of such watercourses, shall be provided, together with such further width or construction, or both, as will be adequate for the stormwater drainage of the area. The width of such easements shall be determined by the County Engineer.
      (6)   Monuments.
         (a)   All plats must depict that durable magnetic markers have been set at all angle and curve points on the outside boundary lines prior to recording the plat. The plat must also indicate that all interior block, lot and witness monuments shall be set within one year after recording the plat.
         (b)   Monuments may be either stone or concrete, or steel bars or iron pipes of least one-half inch in diameter and 14 inches long and shall have affixed thereon the license number of the land surveyor certifying the plat.
         (c)   All monuments shall be certified for accuracy by the owner’s surveyor.
         (d)   It shall be responsibility of the subdivider to ensure that all monuments and markers are maintained in good condition during and following construction and development. All section, quarter section, and sixteenth section corner monuments shall be completely and adequately described and tied.
      (7)   Stormwater management facilities.
         (a)   Location. The applicant may be required by the County Board to infiltrate or carry away by pipe or open ditch any spring or surface water that may exist either previously to, or as a result of the subdivision. Such management facilities shall be located in the road right-of-way where feasible, or in perpetual unobstructed easements of appropriate width, and shall be constructed in accordance with the construction standards and specifications outlined in this section, as required in the applicant’s NPDES permit, and specified by the County Engineer.
         (b)   Accessibility to public storm sewers.
            1.   Where a public storm sewer is accessible, the applicant shall install storm sewer facilities or if no outlets are within a reasonable distance, adequate provision shall be made for the management of stormwaters, subject to the specifications reviewed by the County Engineer and the specifications of the applicant’s NPDES permit.
            2.   If a connection to a public storm sewer will be provided eventually, as determined by the County Engineer and the County Board, the developer shall make arrangements for future stormwater management by a public utility system. Provision for such connection shall be incorporated by Inclusion in the performance bond required for the subdivision plat.
         (c)   Accommodation of upstream drainage areas. A culvert or other drainage facility shall in each case be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the subdivision. The County Engineer shall review plans and specifications provided by the applicant’s engineer to determine the necessary size of the facility, based on the provisions of the construction standards and specifications assuming conditions of maximum potential watershed development permitted by the zoning ordinance.
         (d)   Effect on downstream drainage areas. The Soil Conservation Service and/or the County Board shall also study the effect of each subdivision on existing downstream drainage facilities outside the area of the subdivision. Local government drainage studies, together with such other studies as shall be appropriate, shall serve as a guide to needed improvements. Where it is anticipated that the subdivision’s post-development stormwater runoff will overload an existing downstream drainage facility, the County Board may withhold approval of the subdivision until provision has been made to adequate accommodate the post-development stormwater runoff. No subdivision shall be approved unless adequate drainage will be provided to an adequate drainage watercourse or facility.
         (e)   Floodplain areas. The County Board, may when it deems it necessary for the health, safety or welfare of the present and future population of the area and necessary to the conservation of water, drainage and sanitary facilities, prohibit the subdivision of any stream or drainage course. These floodplain areas shall be preserved from any and all destruction or damage resulting from clearing, grading or dumping of earth, waste material or stumps except at the discretion of the County Board.
      (8)   Public sites and open spaces.
         (a)   Where a proposed park, playground or open space is located in whole or in part in a subdivision, the County Board shall require that such area or areas be shown on plats in accordance with the requirements specified in this section. Such area or areas shall be dedicated to the township, county or to a homeowners’ association responsible for maintenance, by the subdivider if the County Board approves such dedication.
         (b)   The Planning Commission shall require that plats show sites of a character, extent and location suitable for the development of a park, playground or other recreation purposes. The Planning Commission may require that the developer satisfactorily grade any such recreation areas shown on the plat.
         (c)   In all new major subdivisions the Planning Commission shall require 5% of the gross area of the subdivision to be dedicated for public recreation space, school sites or other public use with such percentage being in addition to property dedicated for streets, alleys, easements or other public ways, or contribute fee-in-lieu to a capital fund for recreational facilities. When a subdivision is too small for the practical dedication of public land or if no land in the subdivision is suitable for such use, the subdivider shall be required by the county to pay a fee equal to 5% of the land value prior to subdivision. The land value shall be determined by utilization of assessment records and formulas that apply thereto of the land subdivided at its highest and best use. There may be additional open space requirements under the conservation subdivision requirements in subsection (F) below.
         (d)   Where a private park, playground or other recreational area shall have been drawn on the final plat, the County Board may also require the filing of a written agreement between the applicant and the lot owners covering the cost of grading, development, equipment and maintenance of any such recreation area.
         (e)   Previously subdivided property from which a park dedication has been received, being resubdivided with the same number of lots, is exempt from park dedication requirements. If, as a result of resubdividing the property, the number of lots is increased, then the park dedication or per lot cash fee must apply only to the net increase of lots
      (9)   Copies of plats supplied to Commission. Copies of all plats within shoreland areas approved by the county shall be submitted to the Commissioner of Natural Resources within ten days of approval by the county.
   (D)   Plats; submission procedure and data.
      (1)   Sketch plan.
         (a)   Prior to the filing of an application for approval of the preliminary plat, the subdivider shall submit for review with the Zoning Administrator and Planning Commission, subdivision sketch plans which shall contain the following information: tract boundaries; north point; description of nature and purpose of tract; streets on and adjacent to the tract; significant topographical and physical features; proposed general street layout; and proposed general lot layout.
         (b)   Such sketch plans will be considered as submitted for informal and confidential discussion between the subdivider, the Zoning Administrator, and the Planning Commission. Submission of a subdivision sketch plan shall not constitute formal filing of a plat with the Commission.
         (c)   As far as may be practical on the basis of a sketch plan, the Commission staff will informally advise the subdivider as promptly as possible of the extent to which the proposed subdivision conforms to the design standards of this ordinance and will discuss possible plan modifications necessary to ensure conformance.
      (2)   Preliminary plat.
         (a)   Procedure.
            1.   Report. The County Planner shall submit a report to the Planning Commission concerning the feasibility of the proposed plat and its conformance with the requirements of this ordinance. If the County Engineer is submitting the preliminary plat, the report shall be submitted by another qualified person who shall be selected by the Planning Commission.
            2.   Recommendations of the affected townships, Soil and Water Conservation Districts and Watershed District. The developer shall submit the preliminary plat to the affected township (to the Township Clerk by certified mail or hand delivery with written acknowledgment), soil and water conservation district, and watershed district when the preliminary plat has been submitted to the Planning and Zoning Department. The affected township, soil and water conservation district and watershed district shall have 25 days from the date the preliminary plat was submitted to the Planning and Zoning Department in which to submit its written recommendation to the Planning and Zoning Department, regarding the proposed preliminary plat. Such recommendation shall indicate approval or disapproval, reasons for such a recommendation and may include recommended changes to the proposed preliminary plat. If no recommendation is forthcoming from the township within the 25 days or if a written recommendation is received in less than 25 days, the Planning Commission may proceed with the necessary public hearing. The application shall not be considered complete until comments have been received by the impacted township, the township has waived any rights to comment or the township’s 25-day review period has expired.
            3.   Consideration by the Planning Commission. A petition for approval of a preliminary plat shall be submitted to the Planning Commission which shall hold a public hearing on the petition within 30 days of its submission to the county. Notice of the time, place, subject matter and purpose of the public hearing shall be published in the official newspaper of the county at least ten days before the hearing. Written notice of the public hearing shall also be sent at least ten days before the hearing to all owners of record within one-half mile of the affected property and also to the affected board of town supervisors and municipal council of any municipality within two miles of the affected property. After completion of it deliberations, the Planning Commission shall within ten days make a recommendation to the Board of County Commissioners along with a report on its findings. In case the plat is disapproved, the subdivider shall be notified of the reason for such action.
            4.   Consideration by the County Board.
               a.   A petition for approval of a preliminary plat which has been reviewed by the Planning Commission shall be submitted to the County Board which shall hold a public hearing thereon and either disapprove or approve the petition within 60 days of the submission of a completed application to the county. Notice of the public hearing shall be given in the same manner as provided in § 3.01(C) (Notification Requirements). After completion of its deliberations, the County Board shall within 60 days of the submission of a completed application to the county act on each plat, which has been recommended for approval by the Planning Commission.
               b.   A petition for approval of a preliminary plat which has been disapproved by the Planning Commission may be submitted to the County Board by the petitioner. The petitioner shall have the right to petition within 30 days after receipt of notice of the decision by the Planning Commission. The County Board shall hold a public hearing thereon and either disapprove or approve the petition. Notice of the public hearing shall be given in the same manner as provided in § 3.01(C) (Notification Requirements).
               c.   Approval or disapproval of the preliminary plat shall be conveyed to the subdivider in writing within 60 days of the submission of a completed application to the county. In case the plat is disapproved, the subdivider shall be notified of the reason for such action and what requirements will be necessary to meet the approval of the County Board. The approval of the preliminary plat does not constitute an acceptance of the subdivision, but is deemed to be an authorization to proceed with the final plat. This approval of the preliminary plat shall be effective for a period of six months, unless an extension is granted by the County Board.
               d.   The subdivider may file a final plat limited to such portion of the preliminary plat which he or she proposes to record and develop at the time, provided that such portion must conform to all requirements of this ordinance. If some portion of the final plat has not been submitted to the County Board for approval within this period, a preliminary plat must again be submitted to the Planning Commission and County Board for approval.

            1.   The subdivider will develop the subdivision according to the development phases agreed upon by the county and the subdivider; stating specifically the development phases;
            2.   The subdivider will cause no private construction to be made on the plat or file or cause to be filed any application for permits for such private construction until all improvements required under this ordinance and those denoted on preliminary plat have been made for each development phase;
            3.   The subdivider will furnish and construct the improvements at his or her sole cost and in accordance with plans and specification of the preliminary plat and of this ordinance;
            4.   The Board of Commissioners may accept a final plat for recording where the owner and/or developer of the platted subdivision furnished a certified check, surety bond or other method of financial assurance acceptable to the Board of Commissioners, in sufficient amount to cover the construction costs of improvements required by this article, and/or agreed to by the subdivider. All improvements allowed to be deferred in this section shall be completed as specified in subsection (E)(1)(b) below;
            5.   The subdivider will guarantee completion of the required improvements within two years from the date the final plat was approved by the County Board unless an extension of time is granted by the County Board upon the recommendation of the Planning Commission; and
            6.   The subdivider agreement shall also be the responsibility party and source of funding to ensure the long-term maintenance of improvements that are not dedicated to the county.
         (b)   Financial guarantee required.
            1.   Developers shall be allowed to complete roads and other public improvements prior to recording of the final plat. This work shall be completed within one year of approval of the plat. If the improvements are not completed within a year, the Board of Commissioners may accept a final plat for recording where the owner and/or developer of the platted subdivision furnished a certified check, surety bond or other method of financial assurance acceptable to the Board of Commissioners, in sufficient amount to cover the construction costs of improvements required by this article, and/or agreed to by the subdivider. All improvements allowed to be deferred in this section shall be constructed within two years of approval of the plat, unless an extension of time is applied for and granted by the Planning Commission and Board of Commissioners, as set forth in herein. New or adjusted Engineer’s cost estimates shall be reviewed by the County Engineer to determine whether they adequately reflect current construction costs when extensions of time are requested, or at any other time deemed appropriate by the County Engineer.
            2.   The subdivider’s engineer of record shall present a final itemized cost estimate for required and proposed improvements to the Planning Department with the final plat. Such engineer’s cost estimate shall be forwarded to the County Engineer for review and verification of costs.

The County Engineer shall issue any authorization under this section in writing and shall transmit a copy of such authorization to the Planning Commission and the County Board.
         (g)   Proper installation of improvements. If the County Engineer and/or County Zoning Administrator shall find, upon inspection of the improvements performed before the expiration date of any performance bond, that any of the required improvements have not been constructed in accordance with plans and specifications filed by the subdivider, he or she shall so report to the County Board and Planning Commission. The Zoning Administrator then shall notify the subdivider and, if necessary, the bonding company, and take all necessary steps to preserve the county’s rights under the bond.
         (h)   Public acceptance of required improvements. Approval by the County Board of a final plat shall not be deemed to constitute or be evidence of any acceptance of any municipality, town, county or the state of any street, required improvement, easement, or other right-of-way shown on such final plat unless specifically so stated on the final plat. The acceptance shall be made by the County Board of a municipality, town, county or state.
         (i)   Certificate of satisfactory completion. The County Board will not release nor reduce a performance bond until all requirements have been satisfactorily completed. After review and inspection of the required improvements by the County Engineer, the County Board shall require a statement from the subdivider’s engineer certifying that the required improvements are satisfactorily completed. The County Engineer may designate a consulting engineer licensed in the state to complete this work. If a consulting engineer is utilized, all expenses incurred shall be paid by the subdivider.
         (j)   Maintenance of improvements. A subdivider shall be required to maintain all improvements within the subdivision until acceptance of the improvements by the County Board or affected town board. For improvements not accepted or dedicated to the county, the subdivider shall execute and submit to the County Board an agreement, which shall be binding on the subdivider, the subdivider’s heirs, personal representatives and assigns, which provides for the long-term maintenance of the improvements.

      (4)   Grading, sediment and erosion control. As required by county standards, grading and sediment control plans shall be approved prior to the start of any grading, excavation, fill or other construction activities integral to the development of the subdivision, including roads, drainage ditches, sediment basins and buildings. The sediment and erosion control must be in compliance with the site’s NPDES permit.
      (5)   Accommodating future public water supply and sewerage facilities.
         (a)   Where determined appropriate by the Planning Commission, subdivisions shall be designed so as allow for the future installation of community or public water supply and sewerage facilities in the most efficient and economical manner. Utility easements shall be reserved in all locations necessary for the future installations of public water facilities.
         (b)   Where individual water supply and sewerage is used and future public utilities are designed to be accommodated, the plat shall include a note using language approved by the Planning Commission indicating that such systems are interim and that they shall be discontinued and connection made to public facilities when they become available.
         (c)   Every subdivision required to accommodate a future community or public water system shall provide an adequate number of appropriately spaced fire hydrants and other necessary fire protection facilities. The source of water supply and quantity and location of the fire hydrants and other fire protection facilities shall be sufficient as required by the city most adjacent to the proposed development.

         (e)   Notice; failure. In the event the person or entity responsible for administration of the long-term management plan fails to administer and perform all or any portion of the plan relating to common open space, the county may serve written notice upon such person or entity setting forth the manner in which the such person or entity has failed to administer and perform the plan. The notice shall set forth the nature of corrections required and a reasonable time within which to complete corrective action. If corrective action is not completed within a reasonable time, the county may, but the county is not required to, assume responsibility for administration and performance of the plan with respect to such failures, and in furtherance of such action the county may enter the premises and take all corrective action as may be reasonable, including extended maintenance. The costs of such corrective action may be charged to the person or entity responsible for administration of the long-term management plan or individual property owners who make up a homeowners’ association and may include administrative costs. The costs shall become a lien upon and assessed against the properties that have the right of enjoyment of the common open space.
      (5)   Common utilities. Individual well and septic systems are allowed in conservation subdivisions; however, common utilities (shared water and/or sewer or septic systems) are an option. Common utilities shall meet State Pollution Control Agency standards for sewage treatment systems and be approved by the County Public Health Services Department. Communal drainfields for shared septic systems may be partially or completely located in designated open space, provided that:
         (a)   The dedicated open space parcel containing the communal drainfield is owned in fee by a owner’s association which owns non-open space land within the subdivision and in which membership in the association by all property owners in the subdivision shall be mandatory; or communal drainfields in common open space with conservation easements may be owned by a public or non-profit entity;

      (6)   Lot and building site design. Lots and building sites shall be designed to achieve the following objectives listed in order of priority:
         (a)   Locating individual and communal septic systems on the most suitable soils for subsurface septic disposal;
         (b)   Locating lots and building sites on the least fertile soils for agricultural uses, and in a manner which maximizes the usable area remaining for such agricultural use;
         (c)   Locating building sites within any non-production forest land contained in the lot, or along the edges of open fields adjacent to woodlands only as a means to reduce the impact on agriculture, to provide summer shade and shelter from winter wind, and/or to enable buildings to be visually absorbed by natural landscape features;
         (d)   Locating building sites in areas least likely to block or interrupt scenic vistas as viewed from roads; and
         (e)   Locating building sites to minimize the impact of blocks of forest land and to maximize the continuity of forest lands.
      (7)   Buffer zones. Buffer zones of at least 100 feet shall be required between residential structures and agricultural uses. The buffer areas shall be appropriately planted with native grasses, forbs, shrubs and trees, and/or permanent agriforestry features such as fruit or nut trees, and/or a windbreak. Roads may be substituted for the buffer if the road creates an effective barrier separating yards from agricultural uses as determined by the Zoning Administrator.
      (8)   Streets. Streets within the conservation subdivision shall be developed according to the following standards that promote road safety, minimize visual impacts and minimize impervious surfaces.
         (a)   Streets shall be designed to minimize the visual size and scale of the development and help discourage excessive speeds.
         (b)   Street widths and construction shall conform to the width and standards contained in the street cross section without curb and gutters (or rural cross section) as adopted by the county.
         (c)   Street surface for local streets within the subdivision may be gravel, or other surface with high permeability, unless the streets are an extension of existing paved roads.
         (d)   The number of local street intersections with collector and arterial roads should be minimized, however, the applicant must demonstrate that such intersections are adequate, have the capacity to handle traffic generated by the proposed project, and will not endanger the safety of the general public.
         (e)   If conservation subdivisions abut one another or existing development, direct links should be made to emphasize the connection between existing and new development.
      (9)   Subdivision process. The subdivision process for a conservation subdivision shall comply with county subdivision procedures and at a minimum shall include the following:
         (a)   The pre-application meeting with the Zoning Administrator to discuss:
            1.   The conservation theme;
            2.   The county design guidelines;
            3.   Any proposed common ownership plans for land and structures; and
            4.   Management and ownership of designated open space.
         (b)   In addition, for sketch plan document requirements for major subdivisions, the sketch plan for a conservation subdivision must include:
            1.   A mapped resource inventory that includes:
               a.   Topographic contours at ten-foot intervals; depth to bedrock, and suitability for wastewater disposal systems;
               b.   Hydrologic characteristics, including surface water bodies, floodplains, wetlands, natural swales and drainageways; and
               c.   Vegetation present on the site according to cover type (pasture, woodland and the like) and vegetative type (classified as generally deciduous, coniferous or mixed), and described by plant community (such as the State Department of Natural Resources Natural Heritage Community types), relative age and condition, also noting trees with a caliper of more than 18 inches.
            2.   A site analysis that identifies, precisely locates, and for: a. and b. calculates the acreage of:
               a.   Primary conservation areas, including protected wetlands, floodplains, natural resource protection zones, steep slopes;
               b.   Secondary conservation areas;
               c.   Special views;
               d.   Connections to adjacent open space;
               e.   Net developable acreage and allowed gross density as allowed by the base zoning district; and
               f.   Street and open space concept.
            3.   Building setbacks;
            4.   Parcel lines and building placement concepts for residential and accessory buildings;
            5.   Utility easements; and
            6.   If applicable, statement of intent to establish a homeowners’ association.
      (10)   Non-riparian lots. Tier developments shall consider utilization of a common lakeshore area for those lots not having lakeshore frontage. Such areas may be for use only by owners within the subdivision or other means acceptable to the County Board. Road and lot arrangement should meet the provisions of this selection, but also be designed to accommodate the best use of the shoreland to the enjoyment of future residents.
