Any county may assist a street abutter in improving the street serving the abutter’s premises by providing asphalt, concrete, or other supplies or materials. The furnishing of supplies or materials or paying to the abutter the cost thereof and the providing of inspectors and other incidental personnel shall not render the street improvements a public work or improvement subject to competitive bidding. The legislative authority of such county shall approve any such assistance at a public meeting and shall maintain a public register of any such assistance setting forth the value, nature, purpose, date and location of the assistance and the name of the beneficiary.
