1. City Street Improvements — Local Assessments. — A provision of a city charter, that before the city council shall determine to have local street improvements made, the city engineer shall report the probable cost and give the names of the owners of property abutting on the street, and the number of front feet owned by each party, is mandatory, and compliance therewith is essential to a valid assessment of a special tax for such improvements.
2. Same — Power Strictly Construed. — If the Legislature has authority to empower the city to impose the entire costs of improving streets upon abutting property owners, such authority must be clearly given and the mode strictly followed, or the assessment will not be valid.
3. Same — Repeal and Change of Charter. — Under a city ordinance which did not levy any assessments to pay for the work, or make any provision as to the time of payment of the assessments when levied, a contract for street improvements was let. About or soon after the completion of the work the city charter was repealed, and the new charter did not contain any saving clause in reference to executed contracts, and its provision imposed a larger proportion of the cost of such improvements upon abutting property holders than the former charter. Held, that the new charter would not authorize the levy of such a tax upon abutting property owners to pay for improvements already completed.
4. Same — Levy to Satisfy Past Contract. — A provision of a new city charter, that "all contracts for street improvements now outstanding shall be paid for in accordance with this charter," will not authorize the levy of a local assessment upon abutting property owners to pay for improvements that have been completed and have been paid for by the city.
5. Same — Estoppel — Illegality of Method. — Owners of property abutting on a street are not estopped from denying the validity of an assessment to pay for the street improvements, because they petitioned the city to have the work done, and stood by and saw it done, since they did not petition to have it done otherwise than in a legal manner.
