APPLICATION AND PROCEDURES 1. STANDARDS a. Minor subdivisions shall be processed following the same application and review procedures of a major subdivision. b. The application for a minor subdivision shall show or identify the original parcel of which the proposed subdivision was part of five years prior to the date of application. c. The fact that a proposed division creates four or fewer parcels does not automatically create eligibility to employ the minor subdivision procedure if prior or concurrent division of the parcel, that existed five years prior to the date of application, precludes additional divisions through the minor subdivision procedure. d. Complete minor subdivision applications will not be accepted until one day after the date of eligibility, which is five years after the recording of an applicable minor subdivision. For example: A parcel has a minor subdivision recorded on February 1, 1999 and is eligible for subsequent minor subdivision application on February 2, 2004. e. One existing lot split into two lots is considered to be a one-lot subdivision relating to eligibility for a minor subdivision. 2. LEGIBILITY STANDARDS a. Requirements of§ 13.4 A. 3. on legibility standards apply to certified survey maps, except that: 1) A certified survey map shall follow the provisions of Wisconsin Statute § 236.34 and the Wisconsin Platting Manual as compiled and updated by the Wisconsin Department of Administration. 2) The recorded certified survey map shall be on media approved by the St. Croix County Register of Deeds. 3. APPROVAL PROCESS a. A concept review shall be required between the subdivider and Zoning Administrator or his/her designee. The Zoning Administrator may authorize a waiver of the concept review conference in full or in part, if no public improvements or stormwater facilities are required. b. A preliminary certified survey map and accompanying application materials shall be submitted to the Zoning Administrator for review. c. The content of the submittal shall be the same as for a preliminary plat, when public improvements or stormwater facilities are required. The Zoning Administrator may authorize a waiver of a portion of the submittal requirements when public improvements or stormwater facilities are not required or the proposed lot contains an existing building site. d. The process of review by the Zoning Administrator shall be the saine as for a preliminary plat, except that the process shall not include referral to state agencies. The procedures and standards of§ 13.3 and the standards of Wisconsin Statutes § 236.34 shall apply to a minor subdivision. e. A final certified survey map shall be submitted for each minor subdivision.

The procedures and standards of§ 13.4 A. shall apply to a minor subdivision, except that the Zoning Administrator shall approve, approve conditionally or reject the certified survey map within 90 days of its submission. Failure of the Zoning Administrator to take action on the certified survey map within 90 days shall be deemed approval unless other agencies have not responded within the allowable time, there remain unsatisfied objections by other agencies, or unless the review time has been extended by written agreement with the subdivider. g. The form of the certified survey map shall comply with Wisconsin Statutes § 236.34 and shall also contain any additional information required by the Zoning Administrator at either the preliminary or final review stage. h. If approved, the Zoning Administrator shall certify the approval on the final certified survey map. 13.6 REPLATS A. APPLICATION AND PROCEDURES 1. STANDARDS a. A replat is the change in the exterior boundaries of a previously platted subdivision. b. Changing the interior boundaries within a subdivision is a subdivision if the change creates one or more parcels or lots of less than 35 acres and is not a replat. c. A replat that does not alter areas dedicated to the public, or lots or outlots owned in common by the owners of lots within the subdivision, shall be processed as a subdivision under this ordinance. Whether it is processed as a minor subdivision or a major subdivision depends upon the number of lots created. d. A replat that proposes to alter lands dedicated to the public, or lots or outlots owned in common by the owners of lots within the subdivision, shall be similarly processed. The approval of the replat by the Zoning Administrator shall be conditioned upon approval by a court of the alterations of the areas dedicated to the public, pursuant to Wisconsin Statutes §§ 236.40 - 236.44. 13-24 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft /MroY ld�kYl S IW fl YAl1 t P U 9�AI N I u d Nli� 97�lAd�l 9ti1 10� �4& iuf>G l�l.1 1/ I o o n , ......... f�i�lr'�o?n�dn�"�17„r"�f0U717�iU1�P�lJ�N�iY�7Ml11nXf�Vi�ll9lNNllll/!I/IYOI,:�IF�JI,�'�(�p�i!!1✓,�7/Ol,/aUl,.!9Id�1ll11G.�1G161�1I�i�"I�RU�Uf9Y'�Y(Uf��1.Ea!",�Dl.��i�l?v�"alnlArhlf„'�Nll1�M?P��'�I1��6 13.7 DESIGN STANDARDS FOR MAJOR AND MINOR SUBDIVISIONS A.

LANDSCAPE SCREENING AND BUFFER AREA 1. PURPOSE AND APPLICATION a. Landscaping and buffer requirements are established to promote aesthetically pleasing developments that will protect and preserve the appearance, character, health, safety and welfare of the community. b. These standards are intended to: increase compatibility with adjacent land uses by requiring a buffer or screen between uses, minimize the hannful impact of noise, dust, debris, motor vehicle headlight glare or other artificial light intrusions, and other objectionable activities or impacts conducted or created by an adjoining or nearby use; and preserve scenic views and/or otherwise enhance the rural landscape as seen from perimeter roads. c. These landscaping and buffer standards apply to new commercial and industrial development, new residential development adjoining and across from commercial or industrial development, new Conservation Design Development and any unique circumstances identified by Developer's Agreements. d. The buffer area shall be landscaped to screen any commercial or industrial lot that abuts or is across from any area that is not commercial, industrial or other incompatible development. 2. GENERAL STANDARDS a. The buffer shall consist of an area of land located within and along the outer perimeter of a lot or boundary line. The buffer may overlap drainage and/or utility easements; however, plantings should not impede the flow of water within a drainage easement nor should they be located on any portion of an existing or dedicated public road or right- of-way. b. Landscaping within the buffer area shall consist of native plant species. It should include a mix of trees and shrubs and can also include herbaceous materials such as grasses, vines, aquatic plants, wild flowers and other vegetative materials. c. Where space allows, landscape plantings shall be placed in an informal, random pattern to create a naturalized landscape. d. The landscape plantings shall include low-maintenance, drought and salt tolerant species. e. Preserving existing healthy, native, non-invasive vegetation should always take precedence over planting new vegetation and should be encouraged by crediting such preservation toward these landscaping requirements. f. Existing healthy trees and shrubs shall be properly protected from construction activities in accordance with sound conservation practices. g. The landscaped buffer area may contain any combination of preserved natural vegetation or newly installed plantings. It may include berms, fences, or walls. h. If a berm, fence or a wall is used, it shall be visually dominated by planted vegetation and attain 50 percent opacity/coverage within 12 months of planting. The newly planted vegetation should be growing on the residential or existing use side of the fence or wall. 13-52 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft ME i. The Zoning Administrator may waive part or all of the landscaping requirements where there is an opportunity to preserve a unique native landscape such as a native prairie, oak savannah or woodland. 3. MINIMUM LANDSCAPING STANDARDS a. Unless otherwise indicated, the landscaped buffer area requirement is a minimum of 80 plants per area of land 10 feet in width by 100 feet in length. b. A combination of preserved plants or installed plants may be used. If plants are preserved they must be shrubs or trees in order to count toward the requirement. c. A landscaped buffer is required in the following locations: I Along perimeter road rights-of-way/pavements. a) A landscape buffer at least 10 feet in width shall abut the road right-of- way/pavements for at least half of the road right-of-way frontage. If only new plantings are used, the landscaped buffer shall include a hedge of shrubs with a minimum height of 18 inches at time of planting. Shrubs shall be appropriately spaced according to growth requirements of the species for the hedge to attain 80 percent opacity at maturity and shall not exceed a height of 4 feet. b) No landscaped buffer over 2 feet in height that might block any driver's view shall be permitted within the vision clearance triangle of a driveway access or road/railroad intersection. c) The landscaped buffer may include berms, fences or walls. 2) Around the perimeter of parking lots or pavements. a) A landscaped buffer at least 10 feet in width shall abut the perimeter of parking lots/pavements. If an area is newly planted, the landscaped buffer shall include plants with a minimum height of 18 inches at the time of planting. If plants are preserved they must be shrubs or trees in order to count toward the requirement. The buffer shall attain 80 percent opacity at maturity 3) Along property lines abutting residential development or other incompatible uses. a) A landscaped buffer at least 10 feet in width and at least 6 feet in height at time of planting shall abut the neighboring use. The landscaped buffer shall attain 80 percent opacity at maturity d. If berms are used to supplement or replace some of the planting requirements the width of the buffer area must be adequate to accommodate the size of the berm, based on the berm slope, crown, height and form. However, the subdivider shall demonstrate that any reduction in required new plantings shall not reduce the effectiveness of the buffer area screen. e. Berms shall contain side slopes not exceeding 4 feet of horizontal distance to one foot of vertical distance (4:1) with a maximum height of 6 feet and shall be natural in appearance and undulating wherever possible. f. If a hedge or hedge/berm combination is used, the shrubs shall be at least 3 feet in height at time of planting. Shrubs of sufficient screening density shall be spaced according to growth needs of the species for the hedge to attain at least 6 feet in height and 80 percent opacity at maturity. g. Preserved trees and shrubs used as the landscaped buffer must also meet an opacity of at least 80 percent. They shall be at least 6 feet in height. 011,ff rN,nMEN? 09 St. Croix County Land Division Ordinance 13-53 Chapter 13 County Board Draft November 29, 2005 h. The Zoning Administrator may pennit alternative landscape treatments, which shall have a buffering or screen capacity equal to or greater than the requirements set forth here. 4. LANDSCAPING PLAN a. A Landscaping Plan for the buffer area(s) shall be provided by a licensed landscape architect and approved by the Zoning Administrator. It shall include and address: 1) Existing vegetation that will be preserved. 2) Quantity, size, species and root condition of proposed plant materials. 3) Proposed locations for plant materials. 4) Planting method and schedule. 5) An ongoing ownership and maintenance plan for the landscape plantings and existing vegetation. b. If plantings are not installed prior to approval of a final plat, a landscaping schedule shall be specified in a Developer's Agreement. c. Appropriate financial assurances shall be required to cover the cost of installation of plant materials and replacement of all dead, dying, defective or diseased plant material for a period of 18 months. 5. LANDSCAPE MATERIALS a. All plant materials must meet the minimum standards set by the American Association of Nurserymen. b. Landscape species shall be indigenous or proven adaptable to the climate, but shall not be invasive on native species. c. Plant materials shall comply with the following standards: I Minimum plant size shall be as specified in the following table. For the purpose of determining trunk size, caliper inches shall be measured 6 inches above ground level. Plant Type Minimum size ­­ - -7- —. ­— ­ ergreen �Teci in ­ ­T- -Trees iv Deciduous Overstory 2 V2"caliper inches Deciduous Ornamental I V2"caliper inches Shrubs: Evergreen or Deciduous 18" in height 2) Landscape materials shall be tolerant of specific conditions, including but not limited to heat, drought and salt. 3) Existing healthy plant material may be utilized to satisfy landscaping requirements, provided it meets minimum plant size specified in the table above. 4) Landscape materials shall be of a size that allows growth to the desired height and opacity. 6.

I. PARKS AND PARKWAYS 1. STANDARDS a. The Zoning Administrator may require the subdivision to have parks, parkways or trails and determine whether such areas are to be shown as lots, outlots or dedicated areas upon a finding that duly adopted regional, County or local plans, or official maps, call for provision of such parks or parkways, or upon a determination that the parks or parkways are reasonably required to serve the needs generated by the subdivision or by subdividing within the area. b. The Zoning Administrator shall designate the site, configuration and shape of parks and parkways within the subdivision. J. DESIGN STANDARDS FOR SUBDIVISIONS INTENDED FOR COMMERCIAL OR INDUSTRIAL USE 1. PURPOSE a. It is the intent of this section to assure that the layout and construction of commercial or industrial subdivisions satisfy the following standards in addition to the other requirements of this ordinance because these developments can create heavier traffic and more intensive use characteristics than residential land use. b. The appropriateness of a commercial or industrial use within unincorporated portions of St. Croix County is primarily addressed through land use planning and zoning. This ordinance nonetheless requires a suitability evaluation of the proposed subdivision and relevant adjacent land. 1) The evaluation determines suitability and serves as a basis for project design and review of a proposed subdivision. 2) § 13.2 shall apply to a proposed subdivision and at least 1320 ft. of road frontage on each side of the proposed subdivision and equal frontage across the road to depths equal to the greater of the depth of the proposed subdivision or 1000 ft. 3) The evaluation shall address site characteristics and limitations, road and traffic conditions and similar features. 4) If the Zoning Administrator determines that it is possible that the area will develop beyond the confines of the proposed subdivision, the concept review and the subdivision review application shall include a general plan for the area as a context for decisions on the proposed subdivision. 2. GENERAL SUPPLEMENTAL DESIGN AND IMPROVEMENT STANDARDS a. The widths, lengths and shapes of lots shall be suited to the planned use of the land, zoning requirements, and the need for convenient access to roads, control of traffic, the potential phasing or staged growth of the proposed subdivision and the limitations and opportunities presented by the topography. b. Lot layouts shall facilitate assembly of smaller lots into larger parcels. Generally, the overall topography of lots shall not exceed slopes of 6 percent. c. The Zoning Administrator may require deed restrictions for architectural control and appearance consistent with guidelines established by the local community. 11---,--------,----,,—..111,----".—..---,.—,---,,---,,---.---,.--.-,.

All utilities, including electric, cable television, telephone, gas, water and storm and sanitary sewers, except electric power lines exceeding 1200 volts, shall be underground. b. The site layout shall allow for provision of future connection to municipal services for sewer, water and stormwater. 4. SUPPLEMENTAL ROAD STANDARDS a. Minimum road rights-of-way shall be 80 feet unless the right-of-way pre-exists adoption of this ordinance. In this case, the Zoning Administrator, in his/her discretion, may authorize a reduced minimum right-of-way based on the criteria listed in i)below. b. Minimum pavement width shall be 24 feet. c. Minimum turn radii shall be sufficient to handle the size of vehicles likely to use the site. d. Where the subdivision and/or development of the area will likely involve multiple parcels and/or buildings, the design shall include frontage roads, shared driveway accesses or other means of reducing direct access to arterial roads. e. The subdivision review process shall include specification of the internal road network and internal driveway access arrangements to assure that spacing of access points, queuing distances, turn radii, and the like are appropriate to the volumes of traffic and types of vehicles and vehicular movement likely to be associated with the development. f. The Zoning Administrator shall designate a professional engineer to review road plans and submit comments. g. Roads shall be constructed and paved meeting designs approved by a professional engineer designated by the Zoning Administrator. h. The Zoning Administrator may require cross easements where commercial lots are side- by-side to allow linking of parldng areas. i. Road standards for commercial or industrial developments may be increased by the Zoning Administrator. An increase of these standards will be based on relevant information such as town comprehensive plan or official map, driveway access widths, speed limit, number and types of vehicles using the road, parking availability, sound engineering judgment, and any other pertinent information. 5. SUPPLEMENTAL LOT STANDARDS a. In the case of a commercial or industrial subdivision the contiguous buildable area shall be one and one-half acre. b. Site plans shall be submitted that identify the contiguous buildable area and landscaping areas. c. Subdivision review shall include specifications that follow the landscaping screening requirements of§ 13.7 H. of this ordinance for landscaping along the perimeter, entrance and any public roads. d. Any commercial or industrial lot that abuts or is across from any area that is not commercial or industrial shall have perimeter landscape screening that follows the landscaping requirements of this ordinance. 515RENTIMSYMPORM 13-56 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft 090VIENEW e. In design of the subdivision, every effort should be made to protect and retain existing trees, shrubbery and grasses not actually located in rights-of way, drainageways, vision triangles, and the like. Trees should be protected and preserved during construction. K. CONSERVATION DESIGN DEVELOPMENT FOR MAJOR SUBDIVISIONS 1. APPLICABILITY a. Conservation Design Development (CDD)provides an alternative set of design objectives and standards for major subdivision for residential development. 2. PURPOSE a. The purposes of Conservation Design Development (CDD) are as follows: 1) To provide for the unified and planned development of clustered, residential uses which are designed and located to reduce the perceived density of development, while still providing privacy for dwellings, and incorporate, large areas of permanently,protected common open space. 2) To allow for the continuation of agricultural uses in those areas best suited for such activities and when adjoining residential uses are compatible with such activities. 3) To maintain and protect St. Croix County's rural character by preserving one or more of these important landscape elements, including but not limited to those areas containing such unique and environmentally sensitive natural features as woodlands, river and stream corridors, drainageways, wetlands, closed depressions, floodplains, shorclands, prairies, ridgetops, steep slopes, critical species habitat, and productive farmland by setting them aside from development. Such areas contained in primary and secondary environmental corridors, independent environmental resources and potentially productive agricultural land, as identified by the St. Croix County Development Management Plan, are given particular significance for conservation. 4) To connect common open space areas between adjacent properties and create environmental corridors throughout St. Croix County, areas contained in primary and secondary environmental corridors, independent environmental resources and potentially productive agricultural land, as identified by the St. Croix County Development Management Plan, are of particular significance for conservation. 5) To preserve scenic views and to minimize views of new development from existing homes and roads. 6) To provide greater design flexibility in siting dwellings and other development features than would be permitted by the application of standard use regulations in order to minimize the disturbance of rural landscape elements and sensitive areas, scenic quality, and overall aesthetic value of the landscape. 7) To increase flexibility and efficiency in the siting of services and infrastructure by altering road length, utility requirements, drainage requirements, and the amount of paving required for residential development, where possible. 8) To create groups of dwellings with direct visual and physical access to common open space. 9) To permit active and passive recreational use of common open space by residents of the developments and/or by the public. NOREEN ................................. St. Croix County Land Division Ordinance 13-57 Chapter 13 County Board Draft November 29, 2005 10) To reduce erosion and sedimentation by retaining existing vegetation and minimize development on steep slopes. 11) To pen-nit various means for owning common open space, preserved landscape elements, agricultural land, and to protect such areas from development in perpetuity. 12) To create a stewardship approach to common open space by requiring a land management plan for the common open space. 3. DENSITY STANDARDS a. The total number of dwelling units that are allowed in a Conservation Design Development is referred to as the Residential Gross Density. See St. Croix County Zoning Ordinance § 17.21 (6). 4. RESIDENTIAL BASE DENSITY a. The base density or the base number of allowable dwelling units is determined by the yield plan pursuant to § 13.2 C. 3. Existing dwellings that may or may not be part of a farmstead that will be retained shall be counted toward the base density. 5. RESIDENTIAL GROSS DENSITY a. The residential gross density, or the total number of dwelling units that are allowed in a Conservation Design Development, is the residential base density plus 25 percent of the number of dwelling units prescribed by the residential base density.

The lot size allowed under Conservation Design Development (CDD) is called the prescribed lot area. b. For an existing or new farmstead on a site used for Conservation Design Development, the prescribed lot area shall be large enough to accommodate all structures within a building envelope created by a 100-foot setback from all sides of the lot. For barnyards or buildings that contain or will contain livestock or poultry, the setback shall be increased to 300 feet. 13-58 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft U1........ c. The prescribed lot area of new lots shall be that which results from meeting all of the standards and requirements of Conservation Design Development and Chapter 17, St. Croix County Zoning Ordinance. The prescribed lot area cannot be less than one-half acre. 7. MINIMUM COMMON OPEN SPACE AREA a. For Conservation Design Development, the minimum amount of common open space shall be: 1) In the County Residence District, 50 percent of the total site area excluding existing rights-of-way and utility easements. 2) In the County Agricultural Residential District, 65 percent of the total site area excluding existing rights-of-way and utility easements. 3) On other lands not covered in 1) or 2) above Conservation Design Development is permitted as follows: a) 50 percent of the total site area excluding existing fights-of-way and utility easements if the site is in the Urban or Transitional Planning Areas identified in the St. Croix County Development Management Plan. b) 65 percent of the total site area excluding existing rights-of-way and utility easements if the site is in the Rural Planning Area identified in the St. Croix County Development Management Plan. b. The required common open space designated in 7. a. above can be reduced by the minimum amount necessary to prevent any allowable lot from being reduced to an area less than one-half acre in the attempt to meet those common open space requirements. 8. DESIGN AND DIMENSIONAL STANDARDS FOR CLUSTER GROUPS a. All dwelling units shall be in cluster groups. b. The number of dwelling units in each cluster group shall be determined as follows: I For Conservation Design Developments on a site 40 acres or smaller, each cluster group shall be no more than 40 percent of the total number of dwelling units in the development and no less than 15 percent of the total number of dwelling units in the development, except as provided in 3), below. 2) For any Conservation Design Developments over 40 acres, each cluster group shall be between 6 and 16 dwelling units. 3) A Conservation Design Development with a total number of 16 dwelling units or less may contain a single cluster group if all other standards in § 13.7 K. are met. 4) The number of dwelling units in a cluster group may be decreased or increased and each cluster group may be assembled into smaller or larger groupings,provided that the applicant can demonstrate that such an alternative design is more appropriate for the site, and will meet both the general intent and design objectives of this ordinance and the goals and objectives of the St. Croix County Development Management Plan. c. A plat may contain one or more cluster groups. d. All lots in a cluster group shall take access from interior roads.

Each cluster group shall be defined by the outer perimeter of contiguous lots or abutting roads and may contain lots, roads, and cluster group interior open space. When the development does not include individual lots, such as a condominium, the outer perimeter shall be defined as an area encompassed by a line drawn around the units, no point of which is closer to any unit than 75 feet. f. The outer boundaries of the lot lines of each cluster group shall conform to the separation distances in the following table: LIMITING FACTOR - � SEPARATICIhT DISTANCE 1. From other cluster group outer boundaries 100 feet-� 2. From existing and proposed rights-of-way of arterial or collector highways or from state designated scenic roads 100 feet 3.

From active recreation areas, such as courts,playing fields or pools 100 feet g. The dimensional standards specified in § 13.7 K. 8. f.may be reduced under the following circumstances: 1) The separation distances along existing or proposed arterial roads and site boundaries may be reduced to a minimum of 50 feet only if the applicant can demonstrate that existing vegetation, topography or a combination of these form an effective visual screen. The Zoning Administrator may accept constructed berms and planted native vegetation for these reduced separation distances if such items will fonn an effective visual screen and maintenance is included in the CDD management plan. 2) Separation distances in § 13.7 K. 8. f. 1-6 and 8 may be reduced up to 50 percent if the applicant can demonstrate that such reduced setbacks are more appropriate for the site concerned and will improve the project's conformance with the design objectives in § 13.7 K. 2.,the intent of this ordinance, and the goals, objectives and policies of the St. Croix County Development Management Plan. h. All separation areas for cluster groups along existing roads shall be landscaped in accordance with §§ 13.7 H. and K. 10. i. All cluster groups shall be surrounded by open space. j. All lots in a cluster group shall abut common open space to the front or rear. Cluster group internal open space and common open space across from a road shall qualify for this requirement. ,,, ,- , „W -.,,, „fiu '+�/Ir��A&GiV�?OIJIIdrwN�'✓i,�Aldll�l6�d�11111//l�/IOJ1d0,�ilAlr;�DGr�fiNJAPfnD�liUfl�I�E7�0'l�.dOl�O/�Il1l�u;2��1�Jf.)lfl�//�0,��10��'i/h'rYIG�iP�l�llp/OI�i7kJ0//'CG,����r4Dl4WiU(�YD,�m,+i/f��d190111/.mal�,t7�CJ00JD%��;f1D!/1�hI�INYODIP�lG21211161U1��'10�1SI1�111t�0A1�'�O�,1dIdHd�IJJ��Il1i,�NYIPUG�I�,d N'l�1GiJ„�9DlUllAi/0„JIIOIY,?�'��,Yi02,�/9�.�0!9elP�rnN�fNG��,�,&yIJO/%✓� 13-60 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft ammum ommignommsm gommum ......... k. Cluster groups shall be defined and separated by common open space in order to provide direct access to common open space and privacy to individual lots or yard areas. Roads may separate cluster groups if the road right-of-way is designed as a vegetated center median. 1. Cluster groups containing 11 or more dwelling units must provide internal open space at a minimum rate of 2,000 square feet per dwelling unit. Such open space shall meet the following standards: 1) Internal common open space located within cluster groups shall be counted toward meeting the overall minimum common open-space area requirement. 2) The internal open space should be configured as a cul-de-sac island, a loop lane, an island within a larger loop or an "eyebrow" (a semi-circular loop), an island in a center median road, a common green area, or other configurations that yield internal open space within cluster groups. Common green areas surrounded by lots on up to three sides shall be designed as a common space for use by all residents within the cluster group. 3) Internal open space may contain pervious surface parking areas, but these shall not be included in the required minimum 2,000 square feet of internal open space per dwelling unit or minimum common open space area requirement. in. Cluster groups smaller than 11 dwelling units may contain internal open space that is consistent with § 13.7 K. 8. 1. 2). Such internal open space may be included in the minimum common open-space area requirement if it contains at least 2000 square feet. Such internal open space may contain parking areas,but these shall not be included in the minimum common open-space area requirement. n. Internal open space within cluster groups is not subject to the design standards for common open space areas in § 13.7 K. 9. o. In locating cluster groups, disturbance to woodlands,hedgerows, and individual mature trees shall be minimized. When the objective is to preserve productive agricultural land and large areas of contiguous land suitable for agricultural use, dwellings maybe located within woodlands,provided that some of the canopy on individual wooded lots is maintained. See § 13.7 K. 9. b. 8). 9. DESIGN STANDARDS FOR COMMON OPEN SPACE AREAS a. On all sites developed under the Conservation Design Development regulations, the minimum amount of common open space area, as set forth in § 13.7 K.7., shall be set aside as protected common open space. b. Common open space shall comply with the following design standards: 1) The location of common open space shall be consistent with the design objectives in § 13.7 K. 2., and the goals, objectives and policies of the St. Croix County Development Management Plan. 2) All open space areas shall be part of a larger continuous and integrated open space system. At least 75 percent of the common open space areas shall be contiguous to another common open space area. For the purposes of this section, contiguous shall be defined as either physically touching or located within 100 feet across a public right-of-way, for example, on opposite sides of an internal road. ]mom MINHUNINA2 rY, "WEN St. Croix County Land Division Ordinance 13-61 Chapter 13 County Board Draft November 29, 2005 ........... 3) Common open space shall, to the greatest extent possible, protect site features identified in the site inventory and analysis as having particular value in preserving rural character and conserving natural resources in compliance with the intent of this ordinance and consistent with the goals, objectives and policies of the St. Croix County Development Management Plan. a) The protection of primary and secondary environmental corridors, independent natural resources and potentially productive agricultural land as identified in the St. Croix County Development Management Plan is particularly significant. b) It is recognized that there may be different open space preservation objectives that will result in different areas being set aside as open space. Developments designed to preserve rural character values may look much different from developments striving to preserve viable agricultural land. c) Applicants must provide an explanation of the open space objectives achieved with their proposed development. 4) Natural features shall generally be maintained in their natural condition. If recommended by a professional with pertinent qualifications, the Zoning Administrator may authorize a modification to improve the natural features' appearance or restore their overall condition and natural processes, in compliance with an approved management plan, as described in § 13.2 C. 6. a. Pennitted modifications may include: a) Woodland or forest management. b) Reforestation. c) Meadow or prairie management. d) Wetlands management. e) Streambank protection. I) Establishing native, non-invasive vegetation in buffer areas. 5) All wetlands, floodplains, unique wildlife habitat areas, slopes 25 percent or greater, closed depressions and at least 80 percent of a primary environmental corridor, as identified in the St. Croix County Development Management Plan, shall be contained in common open space. The requirement that at least 80 percent of a primary environmental corridor be contained in common open space can be reduced under the following conditions: a) The site is predominantly primary environmental corridor and development at the permitted density would not be possible without encroaching further on the primary environmental corridor. b) It can be demonstrated that additional development within the primary environmental corridor meets the overall objectives of this ordinance. c) All wetlands, floodplains, unique wildlife habitat areas, slopes 25 percent or greater, and closed depressions remain in common open space. d) Any reduction of a primary environmental corridor included in common open space below 80 percent shall be the minimum needed to achieve maximum permitted density or a stated open space objective. 6) Common boundaries with existing or future open space on adjacent sites shall be maximized. 7) In order to preserve scenic views, ridgetops and hilltops should be contained within common open space wherever possible. 13-62 St Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft n rU�dW.PGI�HPCfSfu7ChDdJ�(2�U(�fG,7ZM2lIVntl�l�ll,//�lJl�In�i�llll�il�`�'L�1.111i,DlUIG'�lfl/llF;//11/P'�:1llIA(Uf,AID(I,�riO>li1MRU1�dS31k�01:i�'R�%i�I1H�AI�(Nl�i7(�'PI7JI„pAlCf�20`6�R>XIIG�u��POi�"��r,P,'P�;11NI�l�A1PrG1y�1��,�Ad�Ultlif�l�P,��IOJ,YIf„Vlif��rl�ll�l4YVG",1td'�'�^%PdVP£rr�r��'MVJI�frrlUr7�'�'�i�!k4fr�2,MWr�i�fl�"N+�d(�YV�i'IOCIVk71fVS�f�Y�7�a"1XI� 8) At least 80 percent of the area of existing woodlands shall be contained within common open space; 20 percent of the area of existing woodlands may be used for lots and residential development. This limitation may be exceeded under the following conditions: a) The site is primarily wooded, and development at the permitted density would not be possible without encroaching further on the woodlands. b) It can be demonstrated that additional development within the woodlands meets the overall objectives of this ordinance. c) The stated objective is to preserve productive agricultural land. d) Any encroachment on the woodlands beyond 20 percent shall be the minimum needed to achieve maximum permitted density or a stated open space objective. 9) Any development of woodlands 40 acres or larger with at least one-quarter mile of width shall have cluster groups arranged around the periphery of the woodlands to preserve as much of the woodlands interior habitat as possible. The arrangement of the cluster groups around the periphery shall preserve natural undisturbed corridors to the interior. 10) No common open space area shall be less than 10,000 square feet in area and not less than 30 feet at its smallest dimension, with the exception of internal open space within cluster groups, as described in § 13.7 K. 8. 1. and m. Open space not meeting this standard shall not be counted toward the total required minimum common open space area. 11) Under no circumstances shall all common open space be isolated in one area of the development. Common open space shall be distributed appropriately throughout the development to properly serve and enhance all dwelling units, cluster groups, and other common facilities. 12) Common open space shall include lands located along existing public roads in order to preserve existing rural landscape character as seen from these roads, and shall, in no case, contain less than the required buffer, setback area, or separation distance. 13) To ensure adequate protection of natural and cultural features, no more than 25 percent of common open space shall be used for active recreational purposes. 14) When common open space is utilized for some or all of the permitted sewer and water facilities, then an easement shall be granted which describes the right of the individual property owner to have access to the common open space to construct, maintain, gain access and/or replace a private sewer or water facility. Additionally, the restrictive agreement on the common open space utilized for sewer or water facilities will include appropriate limitations to prevent compaction of the soils used for sewage treatment. c. Safe and convenient pedestrian access and access for maintenance and emergency purposes shall be provided to common open space areas that are not used for agricultural purposes, in accordance with the following: 1) At least one access point per cluster group shall be provided, having a width equal to or greater than 50 feet within the cluster group. 2) This width may be reduced to no less than 16 feet if the applicant can demonstrate that, due to natural site conditions, meeting the above requirement would run counter to the objectives of this ordinance. r i r 2/fdJ(�w(?a✓�illl�r�ll�il?1Lld(iu�tld�lft�dS��(h7t"��YOduMIHVaiuJ(I+}i4�i!9�'�$Y(411149�dllGfdp✓1fl+�ld?iP'n S�Idd�tZli(C'id�i�r�ll°dfll�NXd�lbiy�llm?Y!'�V11&"61r7PClu�llioM1Fld�llGd�1�IL8�4�!/ll?JR�!,A�Y�1111b1PJln'�1�!(QIPI'2@!!h>Jd�Ctr/tF9�7�NIU�'19�i(7o!➢IGkI(vNGiIV'(I(dYPEIPIGIA6Pr�i7lfllUfOl��1}llY�XWPFf&ViDiIIW�nI!(C�1�O�,r„?lr�7liDII�dIAfr(U9�'�6lUd�IV�fWIIY�M(f�d14'i�'t42/!!b//ADNifl7�(flNNZ'G4�fI110�60+40.14Y({W�90V°W�V1E St. Croix County Land Division Ordinance 13-63 Chapter 13 County Board Draft November 29, 2005 OWN"WRA 3) This access may be in the form of an easement. 4) Access to common open space used for agriculture may be restricted for public safety and to prevent interference with agricultural operations. d.

LANDSCAPING FOR CONSERVATION DESIGN DEVELOPMENT a. Preservation of existing native vegetation. I For the purpose of conserving native vegetation and in recognition of the time value of existing native vegetation, the preservation of existing native, non- invasive vegetation shall generally be preferred to the installation of new plant material, and the excavation of sites shall be minimized. 2) Within all required separation areas between cluster groups and external roads and site boundaries, existing woodlands and hedgerows shall be retained to the maximum extent possible. 3) Suitable existing native vegetation shall be credited toward the landscaping requirements of this ordinance when it would equal or exceed the desirable visual impact of the new required plant material after two years of growth. 4) All new landscaping to be installed and existing native vegetation to be preserved shall be protected in accordance with the standards specified in this ordinance. b. Trees Along Roads. I) Trees of native species shall be planted along internal roads within cluster groups. 2) Trees may be planted, but are not required, along internal roads passing through common open space. 3) Informal, irregular or natural arrangements are encouraged for trees along roads, to avoid the urban appearance that regular spacing may evoke. 4) Trees shall be located so as not to interfere with the installation and maintenance of utilities and paths, trails, or sidewalks that may parallel the road. 5) Tree plantings shall comply with all applicable regulations in this ordinance. c. Buffers 1) Within all required separation areas between external roads and cluster groups, a vegetated buffer area at least 25 feet in width shall be maintained or established. Where no natural trees and shrubs exist, native plant materials shall be planted. 2) Where native vegetated buffers do not exist within separation areas between cluster groups, planted buffers using native species are encouraged, to enhance privacy and a rural appearance between cluster groups. 3) Required buffers around wetlands, all waterbodies and drainageways, and closed depressions must be naturally vegetated or planted with native plant species appropriate to the surrounding landscape. 4) Buffers consisting of an informal, irregular or natural arrangement of native plant species combined with infrequent or prescriptive mowing are strongly encouraged, to create a low-maintenance, naturalized landscape. 13-64 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft 'TYPICIA1 , CONV] I'TVIONIAI , ,�,AYMJT (Yfl [A PkAl\l) ROAD TOTALS=7,045 LIN.FT.

Road Classification System: Roads are classified based on many factors, including speed and volume of traffic. Road classifications fall into a four-category hierarchy. The classifications, in descending order are arterial, collector, subcollector and access roads (see diagram below). The Wisconsin Department of Transportation (WisDOT) and the St. Croix County Highway Department determine arterial and major and minor collector road status on their respective systems and the current functional classification will be used. The St. Croix County Planning and Zoning Department, in conjunction with the appropriate municipal jurisdiction, determines subcollector and access roads. Classifications are shown on the St. Croix County Official Functional Classification Road Map. Residential roads may fall into any of these classifications except arterial. The functional descriptions of each of these classifications follow: 0911 13-80 St Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft .......... ----------- a. Arterials: Provide for rapid speed and movement of high volumes of traffic between areas. An arterial road should have no private accesses on it. Its function is to conduct traffic between communities and activity centers and to connect communities to major state and interstate highways. There are two types of arterials,principal arterials and minor arterials. Principal arterials are those highway corridors that have trip length and travel density characteristics of an interstate or interregional nature. Principal arterials, in general, serve all urban areas greater than 5,000 population and may include: interstate highways, freeways, expressways, four-lane divided highways and two-lane highways. Minor arterials are those highways, which in combination with principal arterials, serve cities, communities and other major traffic generators providing intra-regional and inter-area travels. Minor arterials may include four-lane divided highways, two-lane highways and county trunk,highways. b. Collectors: Provide for moderate speed and movement of medium volumes of traffic and distribute traffic from arterial roads. There are two types of collector roads, major collectors and minor collectors. As the principal road within residential or commercial areas, these collectors carry relatively high traffic volumes and convey traffic from arterial roads to lower-order roads. A collector's function is to promote the free flow of traffic; as such, the roads should not have parking or private residential access. A collector's secondary function is to serve abutting land uses. Major collectors provide service to moderate sized communities and other intra-area traffic generators and link those generators to larger population centers and higher function highways. Minor collectors provide service to all remaining smaller communities and tie local traffic generators with the rural surrounding area. Minor collectors are spaced consistent with population density so as to collect traffic and bring all developed areas within a reasonable distance of a higher-order road. c. Subcollectors: Connect with access roads and convey traffic to major and minor collectors. Like an access road, a subcollector provides frontage and access to residential lots but also carries some through traffic to access roads. A subcollector is a relatively low- speed, low-volume road. Subcollectors include all roads not identified as major or minor arterials, major or minor collectors or access roads. Generally, subcollectors are all town roads in the original town road grid system and town roads identified as through roads or subcollectors on a town comprehensive plan or official map. Some roads in a subdivision may be subcollectors instead of access roads if the two ends of the road extend beyond the boundary of the subdivision and one end of the road eventually connects to another subcollector or higher order road. d. Access Roads: Roads designed to conduct traffic between individual parcels or lots and higher order roads. Access roads provide for low-speeds and low volumes of traffic and convey traffic to subcollector, collector and arterial roads. As the lowest-order road in the hierarchy, the access road usually carries little through traffic and includes short roads, cul- de-sacs, and courts. Access roads include local roads within conventional subdivisions, local roads within Conservation Design Development subdivisions, cul-de-sacs, loop roads, lakeshore roads that existed prior to 1974, and roads not otherwise classified located in unincorporated hamlets, including Boardman, Burkhardt, Cylon, Emerald, Erin Comers, Forest, Hersey, Houlton, Huntington, Jewett, Johannesburg and New Centerville. 1. Cul-de-sac: Roads closed at one end with turn-arounds, not platted for extension. 2. Loop: Short, one-way through roads that turn back to the originating road. ..... ......... WITNEVINOW, St. Croix County Land Division Ordinance 13-81 Chapter 13 County Board Draft November 29, 2005 3. Temporary Dead-end: Roads that terminate in a"T" turn-around and are platted for future extension. Functional Classification System Diagram Arterial 0 2. 0 Access 0 aIMD J Subcollector 27. Shoreland: Lands within the following distances from the ordinary high water mark of navigable waters: 1,000 feet from a lake, pond or flowage; and 300 feet from a river or stream or to the landward side of the floodplain, whichever distance is greater. 28. State Subdivision: The division of a lot, parcel or tract of land by the owners thereof, or their agents, for the purpose of transfer of ownership or building development where the act of division creates 5 or more parcels or building sites of 1-1/2 acres each or less in area, or where the act of division creates 5 or more parcels or building sites of 1-1/2 acres each or less in area by successive division within a period of 5 years. 29. Subdivider: Any person,partnership, corporation, or other entity creating a subdivision. 30. Subdivision: A division of a lot, parcel or tract of land by the owner or the owner's agent for the purpose of transfer of ownership or building development where the act of division creates or results in one or more parcels or building sites of less than 35 acres in area. A subdivision can be created by the following means: a. Recording a plat or certified survey map. b. Recording any other document or instrument that creates a parcel not previously created pursuant to this ordinance or its predecessor. c. Foreclosure of a mortgage or a land contract if the foreclosure creates and/or conveys a parcel not previously created pursuant to this ordinance or its predecessor. This subsection is not to be construed as endorsing a policy encouraging rezoning or subdividing of a parcel as a prerequisite to obtaining a mortgage when inconsistent or incompatible with surrounding zoning or uses. 13-82 St. Croix County Land Division Ordinance November 29, 2005 Chapter 13 County Board Draft 31. Unique Wildlife Habitat Areas: Aquatic and/or terrestrial communities that: a. Are composed of physical attributes and/or vegetation that are not common in St. Croix County and that therefore support species or certain life functions of species that are not supported in other locations of the County; b. Are specific locations known to support endangered, threatened or rare species or communities; or, c. Serve as linkages to important habitat in adjoining areas. 32. Watershed: The land area that drains to a common point.

The purposes of Conservation Design Development (CDD) are as follows: (a) To provide for the unified and planned development of clustered,residential uses which are designed and located to reduce the perceived density of development, while still providing privacy for dwellings, and incorporate large areas of permanently protected common open space. (b) To allow for the continuation of agricultural uses in those areas best suited for such activities and when adjoining residential uses are compatible with such activities. (c) To maintain and protect St. Croix County's rural character by preserving one or more of these important landscape elements, including but not limited to those areas containing such unique and environmentally sensitive natural features as woodlands, river and stream corridors, drainageways, wetlands, closed depressions, floodplains, shorelands,prairies, ridgetops, steep slopes, critical species habitat, and productive fannland by setting them aside from development. Such areas contained in primary and secondary environmental corridors, independent environmental resources and potentially productive agricultural land, as identified by the St. Croix County Development Management Plan, are given particular significance for conservation. (d) To connect corm-non open space areas between adjacent properties and create environmental corridors throughout the County. Areas contained in primary and secondary environmental corridors, independent environmental resources and potentially productive agriculturalland, as identified by the St. Croix County Development Management Plan, are given particular significance for conservation. (e) To preserve scenic views and to minimize views of new development from existing homes and roads. (f) To provide greater design flexibility in siting dwellings and other development features than would be permitted by the application of standard use regulations in order to minimize the disturbance of rural landscape elements and sensitive areas, scenic quality, and overall aesthetic value of the landscape. (g) To increase flexibility and efficiency in the siting of services and infrastructure by altering road length,utility requirements, drainage requirements, and the amount of paving required for residential development, where possible. (h) To create groups of dwellings with direct visual and physical access to common open space. (i) To permit active and passive recreational use of common open space by residents of the development and/or the public. (j) To reduce erosion and sedimentation by retaining existing vegetation and minimizing development on steep slopes. (k) To permit various means for owning common open space,preserved landscape elements, agricultural land, and to protect such areas from development in perpetuity.

PURPOSE a. The purpose of this section is to promote the public safety, welfare and convenience by easing congestion on the public roads through a system of standards and regulations for limiting access to public roads and establishing setbacks from road rights-of-way. 2. JURISDICTION a. The jurisdiction of this section shall include lands abutting all freeways and expressways, principal arterials, minor arterials, major collectors, minor collectors, subcollectors and access roads. b. The functional/jurisdictional classification of existing roads is located on the St. Croix County Official Functional Classification Road Map available from the Planning and Zoning Department, Highway Department, or Wisconsin Department of Transportation (WisDOT). c. Where a road is located on a city, village or other county boundary, this section does not apply on the portion of the road within the city, village or other county. d. The Zoning Administrator will require approval from WisDOT for setbacks, road connection and driveway access to state and federal highways and on land that is adjoining state and federal highways. WisDOT may require additional standards not identified in this ordinance. e. The Zoning Administrator will require approval from the St. Croix County Highway Department for setbacks, road connection and driveway access to county highways and on land that is adjoining county highways. The County Highway Commissioner may require additional standards not identified in this ordinance. f. The minimum standards in this section shall apply to all roads, unless the town with jurisdiction establishes its own standards for town roads. 3. ROAD CLASSIFICATION SYSTEM a. Roads are classified based on many factors, including speed and volume of traffic. Road classifications fall into a four-category hierarchy. The classifications, in descending order, are arterial, collector, subcollector and access roads, see diagram below. The WisDOT and the St. Croix County Highway Department determine arterial and major and minor collector road status on their respective systems and the current functional classification will be used. The St. Croix County Planning and Zoning Department, in conjunction with the appropriate municipal jurisdiction, determines subcollector and access roads. Residential roads may fall into any of these classifications except arterials. The functional descriptions of each of these classifications follow. „�wF i o ,io i, r rrr� r iir r»i,rrai�r, ,� m�ir iirr�i ,r r r «er ,riir eir�rt a r rrr��,r�ao r r, �r r, a di, i?%d�Ild41lP�Nld&LNGtI killf�'1QJ1/�,Ilki i(�(A/rri'�fiJNO H117J11P�fw6'�N�1U�IfllYGi�(11�6�(lG�d�fi�"SZa�M��ilAi('1a�,//1.elrll/il//0//!//ll//dui,/11/��r%/✓�%i////�//(Il✓�101CrdIIQ�I�A/a(IDU1l1�f�92i6�1PCln O//OC//i%G/G/fi/lry%/Il�lla�i!�cd+�FAllUll��%Mklb",aG81nf�1J otl/�M�A,fl{;�f!!W'l�Ill�fflfl(![1N1�/fit li//l�fa�i�NiN,G,.�r(PIf6�i;6191S�I�V�iI�?�IV9N4f4� 17-10 St. Croix County Zoning Ordinance November 29, 2005 Zoning Ordinance Amendments County Board Draft 1) Arterials provide for rapid speed and movement of high volumes of traffic between areas. An arterial road should have no private accesses on it. Its function is to conduct traffic between communities and activity centers and to connect communities to major state and interstate highways. There are two types of arterials, freeways or principal arterials and minor arterials. Principal arterials are those highway corridors that have trip length and travel density characteristics of an interstate or interregional nature. Principal arterials, in general, serve all urban areas greater than 5,000 population and may include: interstate highways, freeways, expressways, four-lane divided highways and two-lane highways. Minor arterials are those highways, which in combination with principal arterials, serve cities, communities and other major traffic generators providing intra-regional and inter-area travels. Minor arterials may include four-lane divided highways, two-lane highways and county trunk highways. 2) Collectors provide for moderate speed and movement of medium volumes of traffic and distribute traffic from arterial roads. There are two types of collector roads, major collectors and minor collectors. As the principal road within residential or commercial areas, collectors carry relatively high traffic volumes and convey traffic from arterial roads to lower-order roads. A collector's function is to promote the free flow of traffic; as such, the roads should not have parking or private residential access. A collector's secondary function is to serve abutting land uses. Major collectors provide service to moderate sized communities and other intra-area traffic generators and link,those generators to larger population centers and higher function highways. Minor collectors provide service to all remaining smaller communities and tie local traffic generators with the rural surrounding area. Minor collectors are spaced consistent with population density so as to collect traffic and bring all developed areas within a reasonable distance of a higher-order road. 3) Subcollectors connect with access roads and convey traffic to major and minor collectors. Like an access road, a subcollector provides frontage and access to residential lots but also carries some through traffic to access roads. A subcollector is a relatively low-speed, low-volume road. Subcollectors include all roads not identified as major or minor arterials, major or minor collectors or access roads. Generally subcollectors are all town roads in the original town road grid system and town roads identified as through roads or subcollectors on a town comprehensive plan or official map. Some roads in a subdivision may be subcollectors instead of access roads if the two ends of the road extend beyond the boundary of the subdivision and one end of the road eventually connects to another subcollector or higher order road. 4) Access roads are designed to conduct traffic between individual parcels or lots and higher order roads. Access roads provide for low-speed and low volumes of traffic and convey traffic to collector and arterial roads. As the lowest-order road in the hierarchy, the access road usually carries little through traffic and includes short roads, cul-de-sacs, and courts. Access roads include local roads within conventional subdivisions, local roads within Conservation Design Development subdivisions, cul- de-sacs, loop roads, lakeshore roads that existed prior to 1974, and roads, not otherwise classified located in unincorporated hamlets, including Boardman, Burkhardt, Cylon, Emerald, Erin Comers, Forest, Hersey, Houlton, Huntington, Jewett, Johannesburg and New Centerville. ............ ................ .................. ..................- ............... ....................... ..........- ............... .............. 00001111M St Croix County Zoning Ordinance 17-11 Zoning Ordinance Amendments County Board Draft November 29, 2005 4.

We concur with the concerns expressed as far as the proposed 25% financial guarantee being inadequate and agree that setbacks of 25 feet and 50 feet are undesirable. The item the Board feels most strongly about is the fact that there is no provision for public input during plat approval. There is no provision for what happens if the town and county do not agree on a plat. We have an example currently with a subdivision approved by the board but not by the county because they feel a road should go through. The Town Board realized that it was not reasonable to try to put a road through because of the terrain. This is a safety and liability issue. There is a concern that County approval of a plat without public input could result in towns being harnessed with plats that may have roads they do not approve of but have liability for. The Board strong urges that a public process be returned to the ordinance process and a variance process be instituted. The proposed ordinance puts all the power and responsibility on the Zoning Administrator. Towns deserve better than to be left out of the decision making as to what type of plat goes into their municipality. The Hudson Town Board understands the importance of updated zoning and subdivision ordinances. We hope that whatever is passed will not be cast in concrete should it become apparent that adjustments should be made to the ordinances. If changes are to be made, we strongly recommend that there be consultation with the public. Thank you for your time and consideration. Robert W. Waxon Chairman, Town of Hudson Cc: St. Croix County Board Members St. Croix County Planning and Zoning Office December 13, 2005 To: St. Croix County Supervisors From: St. Croix Valley Home Builders Association Western Wisconsin Realtors Association Re: Chapter 13 and 17 Ordinances SUPPORT The St. Croix Valley Home Builders Association and the Western Wisconsin Realtors Association support passage of Chapter 13 and 17 ordinances. Why We Support the New Chapter 13 and 17: • This modernization has been worked on for over three years. It has been reviewed by state experts, local experts, and the general public. It brings County ordinance definitions into harmony with State rules and statutes. It is time to move forward. • It includes the option of conservation design development, a valuable tool of modern land development professionals in other parts of Wisconsin, in Minnesota, and around the country. • It promotes sound land use by implementing clear, modern definitions while allowing for regulatory flexibility that is necessary for good design. It is environmentally strong. • This will be good for land owners and land stewards. It will protect and maximize property values in the county for the long term. The St. Croix Valley Home Builders Association and Western Wisconsin Realtors Association request your support for Adoption of the Chapter 13 and 17 Ordinances.
