(c) The right-of-way and design of streets designated as public shall be in accordance with the minimum right-of-way and construction standards established by the Board of Transportation for acceptance on the State highway system. If a municipal or county subdivision control ordinance is in effect in the area proposed for subdivision, the map or plat required by this section shall not be recorded by the Register of Deeds until after it has received final plat approval by the municipality or county, an until after it has received a certificate of approval by the Division of Highways as herein provided as to those streets regulated in subsection (g). The certificate of approval may be issued by a District Engineer of the Division of Highways of the Department of Transportation.

The plat or map required by this section shall not be recorded by the Register of Deeds without a certificate of approval by the Division of Highways of the plans for the public street as being in accordance with the minimum standards of the Board of Transportation for acceptance of the subdivision street on the State highway system for maintenance. The certificate of approval shall not be deemed as acceptance of the dedication of such streets on the subdivision plat or map. Final acceptance by the Division of Highways of such public streets and placing them on the State highway system for maintenance shall be conclusive proof that the streets have been constructed according to the minimum standards of the Board of Transportation.
(e) No person or firm shall place or erect any utility in, over, or upon the existing or proposed right-of way of any street in a subdivision to which this section applies, except in accordance with the Division of Highway's policies and procedures for accommodating utilities on highway rights-of way, until the Division of Highways has given written approval of the location of such utilities. Written approval may be in the form of exchange of correspondence until such times as it is requested to add the street or streets to the State system, at which time an encroachment agreement furnished by the Division of Highways must be executed between the owner of the utility and the Division of Highways.
The right of any utility placed or located on a proposed or existing subdivision public street right-of way shall be subordinate to the street right-of-way, and the utility shall be subject to regulation by the Department of Transportation. Utilities are defined as electric power, telephone, television, telegraph, water, sewage, gas, oil, petroleum products, steam, chemicals, drainage, irrigation, and similar lines. Any utility installed in a subdivision street not in accordance with the Division of Highways, accommodation policy, and without prior approval by the Division of Highways, shall be removed or relocated at no expense to the Division of Highways.
(f) Prior to entering any agreement or any conveyance with any prospective buyer, the developer ant seller shall prepare and sign, and the buyer of the subject real estate shall receive and sign an acknowledgment of receipt of a separate instrument known as the subdivision streets disclosure statement (hereinafter referred to as disclosure statement.)

This section shall be construed and applied in a manner which shall not inhibit the ability of public utilities to satisfy service requirements of subdivisions to which this section applies.
(j) The Division of Highways and District Engineers of the Division of Highways of the Department of Transportation shall issue a certificate of approval for any subdivision affected by a roadway corridor official map established by the Board of Transportation only if the subdivision conforms to Article 2E of this Chapter or conforms to any variance issued in accordance with that Article.
