When the board proposes the planting, maintenance or removal of any trees in any streets of the city, the city forester, under the direction of the board, shall present the proposal in writing to the city council. The proposal shall:

The proposal shall be accompanied by a diagram showing:

Each lot or parcel of land shall be separately assessed in proportion to its frontage at a rate per front foot sufficient to cover that proportion of the total cost and expense of the work which is to be paid for by means of special assessments.

A proceeding for the planting, maintenance, or removal of trees may also be instituted by a petition to the council of property owners whose property will be among that to be assessed to pay the cost of the proposed improvement. Upon such petition being filed the city forester shall file with the city council a diagram similar to the one accompanying a written proposal of the board for similar improvements, which shall describe the improvement proposed by the petition.

The board or the city forester may plant, maintain, or remove any trees in any street of the city by private arrangement for reimbursement with the owner of any lot or parcel of land upon which or fronting upon which the trees are situate.

The board or the city forester may expend any funds which it may have on hand to plant, maintain, or remove trees. The board or city forester may expend such funds if in its judgment the expenditures will not embarrass or affect the efficient discharge of its duties as defined by this part, or any other law or ordinance, and are advisable and for the best interests of the public. Any planting, maintenance, or removal done under the circumstances specified in this section shall not require the initiation of any proceedings as elsewhere specified in this part, or any other proceedings, or any formal action by the board or by the city council.

Before ordering any improvement specified in either the written proposal of the board or in the petition of property owners, the city council shall adopt a resolution of intention declaring its intention so to do, briefly describing the improvement, the streets which are to be improved, the general nature and the estimated costs and expenses thereof, the kinds of trees to be planted, if any, and fixing a time when the city council shall hear and pass upon protests against the improvement.

If the proposal or the petition contains a provision for the maintenance of trees which are already planted or are proposed to be planted, the resolution shall provide for the maintenance of the trees for the period specified in the proposal, but in any event not to exceed five years.

The city council may order in the resolution of intention, or thereafter, that all or a specified portion of the costs and expenses of the improvement shall be paid out of the treasury of the city from any funds which the city council may designate.

Owners of property which will be assessed to pay the cost of the proposed improvement may protest against the improvement by filing their objections in writing with the city council at any time before the time fixed for the hearing thereof.

The city council shall cause notice to be mailed and set the time and date for a public meeting and public hearing pursuant to Section 54954.6 of the Government Code. If new or increased assessments are proposed, the city council shall comply with the notice, protest, and hearing procedures in Section 53753 of the Government Code.

If the owners of a majority of the front footage involved in the improvement object to the improvement, all further proceedings shall be terminated. If there is a majority protest the proceeding shall not be renewed for a period of six months, and then shall only be renewed by the adoption of another resolution of intention. If a new or increased assessment is proposed, the city council shall comply with the protest procedures in Section 53753 of the Government Code.

On the date fixed by the resolution of intention for the hearing of protests, the city council shall proceed to hear and pass on all protests filed with it, and its decision thereon shall be final and conclusive.

After the hearing, the city forester, under the direction and supervision of the board, shall abandon the improvement or proceed with it, according to the decision of the city council.

If the council decides to proceed with the improvement, it shall, by resolution order the improvement to be made according to the resolution of intention, or with such alterations or changes as it may deem best.

After deducting any contribution to be made by the city, the balance of the entire assessable cost of the improvement between the lot lines, in front of any lot or parcel of land abutting on a street which is to be improved, shall be chargeable to and assessed upon those lots or parcels of land.
