   This chapter shall be known and may be cited and referred to as the “Subdivision Code for the Village of Carol Stream, Illinois”.
§ 7-1-2  PURPOSES.
   While it is obvious that regulations are needed to assure orderly extension of village streets, the other purposes of these regulations are:
   (A)   To ensure sound, harmonious subdivision development and community growth, and to safe-guard the interests of the home owner, the subdivider, the investor and the village;
   (B)   To provide permanent assets to the locality and to the village;
   (C)   To prevent scattered development beyond existing public utilities and prevent excessive development costs;
   (D)   To assure the development of land for optimum use with necessary protection against deterioration and obsolescence;
   (E)   To limit and control the pollution of the environment that can be caused by inadequate or incomplete urban development;
   (F)   To provide common grounds of under-standing and a sound working relationship between the village and the subdivider; and
   (G)   To otherwise promote realization of the Comprehensive Plan.
§ 7-1-3  APPLICATION OF CHAPTER.
   No person shall divide any tract of land or plat any street or easement or otherwise improve any tract of land, right-of-way or easement even if such improvement does not entail the subdivision or platting of land within the village or in any unincorporated area which is located entirely or in part within one and one-half miles of the nearest limits of the village, except in conformity with the provisions of this Subdivision Code. The plans and plats, proposed improvements to be installed, and all procedures relating thereto, shall in all respects be in full compliance with the regulations herein. Acceptance by the village of any improvements made on public property shall be based on the conformity of such improvements with the provisions of this code and in accordance with the procedure stipulated in this Subdivision Code.
§ 7-1-4  GENERAL PROVISIONS.
   (A)   Wherever any subdivision of land or any street for public use shall hereafter be laid out within contiguous territory not more than one and one-half miles beyond the incorporated boundaries of the village, the subdivider thereof, or his or her agent, shall submit first a preliminary plan and then a final plat to the village for its approval of the land to be subdivided or served by the street or easement. The preliminary plan and final plat and all procedures relating thereto shall in all respects be in full compliance with these regulations.
   (B)   Until a preliminary plan for the proposed subdivision or street or easement for public use or the planned unit development is approved:
      (1)   No land shall be subdivided, nor any street laid out, nor any improvement made to the natural land;
      (2)   No lot, tract or parcel of land within the proposed subdivision shall be offered for sale, nor shall any sale, contract for sale or option be made or given; and/or
      (3)   No improvements, such as sidewalks, water supply, storm water drainage, sanitary sewer facilities, gas service, electric service, lighting, grading, paving or surfacing of streets shall hereafter be made by any owner or owners, or his, her or their agent, or by any public service corporation at the request of such owner or owners of his, her or their agent.
   (C)   All offerings or dedications of land to the village for use as streets, highways, alleys, schools, parks, playgrounds or other public uses shall be referred to the Plan Commission for review and recommendation before being accepted by the Village Board or by any other governing authority of the village.
   (D)   Where a tract of land proposed for subdivision is part of a larger, logical subdivision unit in relation to the village as a whole, the Plan Commission may, before recommending approval, cause to be prepared a plan for the entire area or neighborhood, such plan to be used by the Plan Commission as an aid in judging the proposed plat.
§ 7-1-5  INTERPRETATION.
   (A)   In interpretation and application, the provisions of this Subdivision Code shall be held to the minimum requirements.
   (B)   Where the conditions imposed by any provision of this Subdivision Code upon the use of land are either more restrictive or less restrictive to the comparable conditions imposed by any other provision of this chapter or any other law, ordinance, resolution, rule or regulation of any kind, the regulations which are more restrictive or which impose higher standards or requirements shall govern.
   (C)   This chapter is not intended to abrogate any easement, covenant or any other private agreement, provided that where the regulations of this code are more restrictive or impose higher standards or requirements than such easements, covenants or other private agreements, the requirements of this Subdivision Code shall govern.
   (D)   The recommendations of the Plan Commission or lack thereof shall not limit the power of the Board of Trustees to act.

The undersigned hereby certify that, to the best of our knowledge and belief, the drainage of surface waters will not be changed by the construction of such subdivision or any part thereof, or that such surface water drainage will not be changed without adequate provision being made for the collection and diversion of such surface waters into public areas or drains which the subdivider has a right to use, and that such surface waters will not be deposited on the property of adjoining land owners in such concentrations as may cause damage to the adjoining property because of the construction of the subdivision. The undersigned owner or duly authorized agent further acknowledges the existence of the ordinances of the Village of Carol Stream and restricts the future use of the land herein subdivided in that no building permits shall be sought by the undersigned owner or agent or their successors in interest or issued by the village for construction of such land until and unless the construction and the changes in the land brought about by such construction and topographical change comply with the ordinances of the village relating to surface waters, drainage, water retention and detention, including those ordinances assuring the construction of such improvements through the posting of security.

§ 7-2-8  SECURITY FOR SUBDIVISION IMPROVEMENTS.
   (A)   (1)   The Plan Commission shall submit the final plat along with its recommendations to the Village Board of Trustees, and the Village Board of Trustees shall approve such final plat before recording, and such approval shall not be given until the subdivider has complied with the requirements of this section. No building permit shall be issued for construction on such land until the final plat has been recorded and until and unless the Village Engineer determines that all the land shown on the final plat is in compliance with the ordinances of the village relating to surface water, drainage, water retention, detention, land movements not previously approved and security to assure the completion of the improvements has been posted as hereinafter provided.
      (2)   The applicant shall provide cash, an irrevocable letter of credit or a surety bond with sureties acceptable to the Village Manager or Board of Trustees in an amount equal to not less than 115% of the full cost of the improvements as estimated by the Village Engineer and conditioned on the completion and acceptance by the Village Engineer of all improvements. The applicant may be required to provide a security of a larger amount in times of high cost inflation or, if such similar conditions exist. Such amount shall not exceed 125% of the full cost of the improvements. The security shall be given in a form such that after reasonable notice to the owner or developer that the required work has not been completed, the village may compel the completion by the guarantor or withdraw sufficient funds up to all amounts not previously released to complete the required improvements. Where an irrevocable credit or surety bond is posted, such document shall provide that it shall not lapse or be canceled without 90 days prior written notice to the village. Such improvements shall include, but not be limited to, streets, street lights and signals, sidewalks, landscaping of public and common lands, water facilities, storm and sanitary sewers and facilities, retention and detention basins and structures, erosion, sediment control and land movement measures, and where an essential part of the development, common recreational facilities. The documents establishing this security arrangement shall be approved by the Village Attorney. The Village Attorney shall be compensated for his or her services in this regard in accordance with the provisions of § 7-2-3(C). Upon acceptance of such bond, approval of plans and specifications for all improvements by the Village Engineer, and approval by the Plan Commission and Village Board of Trustees of the final plat, such plat may then be recorded; provided, however, that, the portion of the required bond or other guarantee necessary for improvements relating to surface waters, drainage and water retention and detention may be waived, in whole or in part, by resolution of the Village Board for industrial and commercial subdivisions only in those exceptional cases where the Village Board shall determine that it is impracticable to require such development to comply with village requirements regarding surface waters, drainage and water retention and detention at the time of approval of the final plat. The required bond or other guarantee must, however, be posted before building, or land movement permits are issued.
   (B)   The Village Clerk shall not certify the approval of the Board of Trustees on the final plat until the required bond, or deposit of cash or other security or other guarantee either has been filed in its entirety or has been filed for all improvements except for waiver of that portion of such required bond or other guarantee for drainage improvements, all as provided in division (A) of this section.
   (C)   Letters of credit and other forms of security posted with the village may, upon completion of specific public improvements but prior to final acceptance of all public improvements, be reduced, from time to time, by an amount equal to 100% of the cost of such total public improvements. Such reductions shall be approved by the Board of Trustees. Upon final acceptance of such improvements and posting of a maintenance security for the completed and accepted public improvements, such completion security shall be fully released.
   (D)   In the event that any time prior to the final acceptance of the subdivision improvements, the amount of the security remaining unused by the village as cash or not drawn down under the irrevocable letter of credit, or no longer available through the surety, should not be adequate to cause the completion of the uncompleted improvements, the village may upon seven days’ written notice require the applicant, the subdivider or the owner of the property which benefits from the improvements to post additional security in an amount sufficient to cause the completion of the subdivision improvements. The village may take this action on more than one occasion if the amount of the security at any time should be inadequate to permit the completion of subdivision improvements. In the event that there is inadequate security to complete subdivision improvements, the village shall not issue any building or occupancy permits. If the maintenance security previously posted shall be inadequate to cause the repair of the subdivision improvements during the maintenance period, the applicant, the subdivider or the owner of the property which benefits from the improvements shall be required to post a replacement maintenance security which, along with the amount of the security previously utilized, shall be at least equal the security which was required to be posted at the time that the subdivision improvements were accepted.
   (E)   Where the village has caused the completion of subdivision improvements which have not been adequately completed by the applicant, the subdivider or the owner of the property which benefits from the improvements, or where the village accepts maintenance responsibilities for improvements which have not been completed or where bills of sale or other documentation has not been furnished to the village for personal property associated with the subdivision, which will be owned by the village, the applicant, the subdivider or the owner of the property which benefits from the acceptance of maintenance of the improvements by the village shall remain responsible for the full obligations contained within the village ordinances associated with the dedication and improvement of property until such time as all provisions of this code associated with the transfer of ownership and maintenance responsibility to the village have been complied with.
   (F)   The Village Manager is authorized to waive the surety requirements of this section for the installation of any improvements by a governmental agency, provided that the installation of the improvements is for a governmental purpose. For the purpose of this section, the term GOVERNMENTAL AGENCY shall refer to a unit of local government, public taxing body or extension thereof. The Village Manager may require the governmental agency to execute an agreement binding the governmental agency to construct and install the improvements in full accordance with the Carol Stream Code of Ordinances and all applicable laws, ordinances, rules and regulations and to correct any deficiencies in such improvements, as determined by the village.

§ 7-3-1  DESIGN STANDARDS GENERALLY.
   The subdivision of land, including the arrangements, character, extent, width, grade and location of all streets, alleys, crosswalks, easements, sites for parks, playgrounds and schools or other land to be dedicated for public use shall conform to the Comprehensive Plan and official map of the village, and approval of design standards shall be considered on the basis of their relation to existing and platted streets, reasonable circulation of traffic within the subdivision and adjacent land, topographic conditions, runoff of storm water, public convenience and safety, and appropriate relation to the proposed land uses of the area to be served.
§ 7-3-2  STREET STANDARDS.
   (A)   Where such is not shown on the Comprehensive Plan, the arrangements of streets within a subdivision shall either:
      (1)   Provide for the continuation or projection of existing principal streets in adjacent areas; or
      (2)   Conform to a plan for the area or neighborhood approved or adopted by the Plan Commission to meet a particular situation where topographical or other conditions make continuance or conformance to existing streets impracticable.
   (B)   All required street right-of-way widths, and pavement widths, curves, gradients and site distances shall be as shown in “Table 1: Minimum Standards for Street Design”, which is set forth at the end of Ch. 7, Art. 4.
   (C)   Street jogs with centerline offsets of less than 125 feet shall be avoided.
   (D)   It must be evidenced that all street inter-sections and confluences encourage safe and efficient traffic flow and, in general, be at or near right angles and in no case shall a street intersect any other street at less than 60 degrees. An intersection of more than two streets shall not be permitted.
   (E)   Alleys are not permitted in residential subdivisions unless deemed necessary by the Plan Commission and required by the Board of Trustees. Alleys may be provided in business or manufacturing subdivisions.
   (F)   A cul-de-sac street in residential districts shall be not more than 600 feet in length, measured along its centerline from the street centerline to the center of the turnaround. Each cul-de-sac street shall have a terminus of nearly circular shape with a mini-mum right-of-way diameter of 120 feet and a turn-around diameter of 88 feet measured from outer curb to outer curb.
   (G)   Half-streets shall be prohibited, except when recommended by the Plan Commission and approved by the Board of Trustees, and where the Board of Trustees finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided. Wherever an existing dedicated half-street abuts a tract to be subdivided, the other half of the street shall be platted within such subdivision. A half-street shall be graded in accordance with cross-section design standards and profile grades applicable to the entire street width, as established by the Village Engineer and approved by the Board of Trustees. When the outer half of an existing half-street is developed, it shall conform with such established cross-section design and profile grades of the entire street width. The width of a half-street shall be not less than one-half the required right-of-way width of the street. A roadway pavement not less than 20 feet in width and, if recommended by the Plan Commission and approved by the Board of Trustees, a curb along both edges of the pavement, shall be installed in accordance with standards herein set forth.
   (H)   (1)   Provisions shall be made for vehicular access to residential property abutting a major street either:
         (a)   By providing a marginal access road; or
         (b)   By backing lots to the thoroughfare with a planting strip at least ten feet wide along the line adjacent and parallel to the major street.
      (2)   These standards are established for the purpose of providing protection for the residential properties and to provide for traffic safety and the efficient use of the major street for its intended function of accommodating through traffic.
   (I)   The Plan Commission or the Village Board may require a marginal access road along a major street in commercial or industrial zones.
   (J)   Reserve strips controlling access to public utilities, streets or alleys shall be prohibited.
   (K)   Minor streets shall be so laid out that their use by through traffic will be discouraged.
   (L)   Street grades shall provide proper relation between the street and the first floor elevation of the houses or buildings and permit convenient and economical access to and drainage of the lots.
§ 7-3-3  ALLEYS.
   (A)   In commercial, business and industrial districts, definite and assured provisions shall be made for service access such as off-street loading, unloading and parking consistent and adequate for the uses proposed. If, in the opinion of the Plan Commission, such facilities are not adequate, the Plan Commission may permit or require the dedication and improvement of a public alley.
   (B)   Alleys in residential areas shall not be permitted, except where deemed necessary and on the recommendation of the Plan Commission.
   (C)   The width of an alley where permitted or required shall have a minimum width of 24 feet in all zoning districts.
   (D)   Alley intersections and sharp changes in alley alignment shall be avoided.
   (E)   Dead end alleys shall be avoided where possible, but if unavoidable, they shall be provided with adequate turn around facilities at the dead end, as determined by the Plan Commission.
§ 7-3-4  EASEMENTS.
   (A)   Utility distribution or transmission installations serving the subdivision and, when required, storm water drainage ways shall be located in easements as designated on the subdivision plat of record. Such easements shall be located along the rear lot lines or side lot lines at locations of extensions of utility installation between blocks, or continuity of drainage way. They shall occupy not less than the rear ten feet or lot depth of ten feet of lot width adjoining the applicable side lot line, or may be of a greater width if recommended by the Village Engineer and approved by the Board of Trustees. Additional easements at other locations may be recommended for specific conditions by the Village Engineer and required by the Board of Trustees.
   (B)   Easements shall be designed to provide continuity from block to block.
   (C)   Where a subdivision is traversed by a natural drainageway, channel or stream, there shall be provided a drainage easement, conforming substantially with the areas bordering such watercourse that are subject to flooding. The boundaries of such areas subject to flooding shall be as designated in Ch. 7, Art. 1, of this Subdivision Code.
§ 7-3-5  BLOCKS.
   (A)   The lengths, widths and shapes of blocks shall be determined with due regard to:
      (1)   Provision of adequate building sites suitable to the special needs of the types of use contemplated;
      (2)   Zoning requirements as to lot sizes and dimensions within the corporate limits of the village; and
      (3)   Needs of convenient access, circulation, control and safety of street traffic.
