 (from Ch. 34, par. 5-1041)Sec. 5-1041.     Maps, plats and subdivisions.     A county board may prescribe,  by resolution or ordinance, reasonable rules and regulations governing the  location, width and course of streets and highways and of floodplain,  stormwater and floodwater runoff channels and basins, and the provision of  necessary public grounds for schools, public libraries, parks or  playgrounds, in any map, plat or subdivision of any block, lot or sub-lot  or any part thereof or any piece or parcel of land, not being within any  city, village or incorporated town.  The rules and regulations may include  such reasonable requirements with respect to water supply and sewage  collection and treatment as may be established by the Environmental  Protection Agency, and such reasonable requirements with respect to  floodplain and stormwater management as may be established by the County  Stormwater Management Committee established under Section 5-1062 of this  Code, and such reasonable requirements with respect to street drainage and  surfacing as may be established by the  county engineer or superintendent of highways and which by resolution shall  be deemed to be the minimum  requirements in the interest of the health, safety, education and  convenience of the public of the county; and may provide by  resolution that the map, plat or subdivision shall be submitted to the  county board or to some officer to be designated by the county board for  their or his approval. The county board shall have a qualified engineer  make an estimate of the probable expenditures necessary to enable any  person to conform with the standards of construction established by the  board pursuant to the provisions of this Section. Except as provided in  Section 3 of the Public Construction Bond Act, each person who seeks  the county board's approval of a map, plat or subdivision shall post a  good and sufficient cash bond, irrevocable letter of credit, surety  bond, or other adequate security with the county clerk,  in a penal sum sufficient to cover the estimate of expenditures made by the  estimating engineer. The cash bond, irrevocable letter of credit,  surety bond, or other adequate security shall be  conditioned upon faithful adherence to the rules and regulations of the  county board promulgated pursuant to the authorization granted to it by  this Section or by Section 5-1062 of this Code, and in such cases no such  map, plat or subdivision shall be entitled to record in the proper county  or have any validity until it has been so approved.  If the county board requires a cash bond, letter of credit, surety, or any  other method to cover the costs and expenses and to insure completion of the  requirements, the requirements shall be subject to the provisions of Section  5-1123 of this Code.  This Section is subject to the provisions of Section 5-1123.The county board may, by resolution, provide a schedule of fees sufficient  to reimburse the county for the costs incurred in reviewing such maps, plats  and subdivisions submitted for approval to the county board. The  fees authorized by this Section are to be paid into the general  corporate fund of the county by the party desiring to have the plat  approved.For purposes of implementing ordinances regarding  developer donations or impact fees and only for the purpose of expenditures  thereof, "public grounds  for schools" is defined as including land or site  improvements, which include school buildings or other infrastructure  necessitated and specifically and uniquely attributable to the development  or  subdivision in question.  This amendatory  Act of the 93rd General Assembly applies to all impact fees or developer  donations paid into a school district or held in a separate account or escrow  fund  by any school district or county for a school district.No officer designated by a county board for the approval of plats  shall engage in the business of surveying, and no map, plat or  subdivision shall be received for record or have any validity which has  been prepared by or under the direction of such plat officer.It is the intention of this amendatory Act of 1990 to repeal the  language added to Section 25.09 of "An Act to revise the law in relation to  counties", approved March 31, 1874, by P.A. 86-614, Section 25.09 of that  Act being the predecessor of this Section.
