improvements - Expense of connections.

When a petition for improvement is presented, or when the

municipal governing body shall have determined to pave or otherwise

improve any street, avenue, lane, alley or other public place, and

shall have passed the required resolution, the governing body shall

then have the power to:

1. Enact all ordinances, and to establish all rules and

regulations as may be necessary to require the owners of all

property subject to assessment to pay the cost of such improvement;

or

2. Cause to be put in and constructed all utility lines and

connections in and underneath the streets, avenues, lanes and

property, and shall be included in and made a part of the assessment

to cover the cost of the improvement.
