Whenever the public interest or convenience requires, the legislative body of any municipality may install in or along its streets all or any of the following:

If the written consent of the owner of the property is first obtained, work may be done on private property to eliminate any disparity in level or size between the improvement and private property, provided that the legislative body determines in the resolution of intention to order the improvement that it is in the public interest and more economical to do such work on private property than to adjust the work on public property to eliminate such disparity. The actual cost of such work may be added to the assessment of the lot on which the work is done. Nothing in this section limits or restricts the authority of the legislative body to make agreements authorized by Section 1263.610 of the Code of Civil Procedure.

(A) Work deemed necessary to bring real property or buildings, including privately owned real property or buildings, into compliance with seismic safety standards or regulations. The legislative body shall declare that public loans or funds provided to owners of private buildings for seismic strengthening of unreinforced buildings or other buildings, or real property, pursuant to this section constitute a public purpose resulting in a public benefit. Only work certified as necessary to comply with seismic safety standards or regulations by local building officials may be financed. No project involving the dismantling of an existing building and its replacement by a new building or the construction of a new or substantially new building may be financed pursuant to this section, except as otherwise provided in subparagraph (B). Work on qualified historical buildings or structures shall be done in accordance with the State Historical Building Code (Part 2.7 (commencing with Section 18950) of Division 13 of the Health and Safety Code). Any financing for seismic strengthening of a residential structure containing units rented by households specified in Section 50079.5 of the Health and Safety Code before strengthening shall be subject to a regulatory agreement that will ensure that the number of those units in the structure will not be reduced and will remain available at affordable rents pursuant to Section 50053 of the Health and Safety Code as long as any assessments levied pursuant to this section on the parcel on which the structure is located remain unpaid.

No lot, parcel, or building shall be included in the district without the owner’s consent.

(B) Within any area that has been designated by the Governor as a disaster area or for which the Governor has proclaimed the existence of a state of emergency because of earthquake damage, work deemed necessary to repair any damage to real property directly or indirectly caused by the occurrence of an earthquake cited in the Governor’s designation or proclamation, or by aftershocks associated with that earthquake, including work to reconstruct, repair, shore up, or replace any real property or building damaged or destroyed by the earthquake or by its aftershocks. Work may be financed pursuant to this subparagraph only on real property or buildings identified in a resolution of intention to establish a district adopted within seven years of the date that the Governor designates the area as a disaster area or proclaims a state of emergency in the area.

Whenever the public interest or convenience requires, the legislative body of any municipality may install or operate, or install and operate, in or along its streets or any public way or any easement, any of the following:

Following the levy of an assessment pursuant to this division to pay, in whole or in part, the costs and expenses of works, system or facilities authorized by subsection (a) of Section 10100.5 or subsection (a) of Section 5101.5 upon a district benefited thereby, and annually on or before June 30th, the legislative body may prepare and approve an estimate of the expenditures required during the ensuing fiscal year for the maintenance, operation, repair and improvement of such works, system or facilities and shall deduct from such estimate the amount of revenues, if any, which the legislative body estimates will accrue during such year from the operation of such works, system or facilities and will be available to pay costs of such maintenance, operation, repair and improvement.

The legislative body may levy and collect in any year upon and against all of the taxable land and improvements within such district a special ad valorem assessment sufficient to raise a sum of money not exceeding the net amount thus determined but the rate of assessment in any one year shall not exceed twenty-five cents ($0.25) on each one hundred dollars ($100) assessed value as shown on the assessment roll used by the city for city taxation.

The special ad valorem assessment shall be levied, collected and enforced at the same times, in the same manner, by the same officers, and with the same interest and penalties, as in the case of general taxes levied by the city. The proceeds of the assessment shall be placed in a separate fund of the city and shall be expended only for the maintenance, operation, repair or improvement of such works, system or facilities.

The legislative body of any municipality which has entered into an agreement with an owner or owners of land within the municipality whereby the owner or owners have constructed or acquired water system facilities, including wells, pumps, dams, reservoirs, storage tanks, pipes, hydrants, meters or other appurtenances for supplying or distributing a domestic water supply, or sewer system facilities, including sewers, pipes, conduits, manholes, treatment and disposal plants, connecting sewers and appurtenances for providing sanitary sewer service, or capacity in these facilities, and have transferred the facilities or capacity to the municipality to be utilized by it for providing water or sewer service, or both, to the land of the owner or owners, and whereby the municipality has agreed to refund or reimburse to the owner or owners the cost of the facilities or capacity or any portion thereof out of connection fees or other revenues or funds of the municipality, including an assessment levied upon the land of the owner or owners or proceeds from the sale of bonds issued pursuant to this division, may upon obtaining the written consent of the owner or owners conduct proceedings pursuant to this division for the formation of an assessment district over and including the land of the owner or owners and levying an assessment thereon and issuing bonds as authorized by Chapter 7 (commencing with Section 10600), for the purpose of satisfying its refund or reimbursement obligation to the owner or owners. The municipality may, upon obtaining the written consent of the owner thereof, include in the assessment district, and levy an assessment upon, any land which will benefit from the water or sewer system facilities, or both, or capacity therein, whether or not the land is owned by the owner or owners who are parties to the agreement with the municipality, but may not include in an assessment district the land of any owner who does not consent in writing thereto.

Prior to any hearing pursuant to Section 10100.8, the clerk shall cause notice of the hearing to be published pursuant to Section 6066 of the Government Code.

The legislative body may acquire any works or appliances already installed in the streets, of the municipality which are necessary or convenient to supply the municipality or its inhabitants with water, electricity, gas, or other means of heat, illumination, power, or any other public service, and any plants, lands, and rights of way, whether located within or without the municipality, which are necessary or convenient for their use and operation, or may acquire the use of any such works, appliances, and other property. The legislative body may also acquire electric current, gas, or other illuminating agent for power or lighting service pursuant to this division.

Notwithstanding any other provision of this division, whenever the public interest or convenience requires, the legislative body of any municipality may pay fees or expenses or acquire or install any or all of the works and improvements authorized by, and subject to the limitations with respect to those works and improvements set out in, the Improvement Act of 1911 (Division 7 (commencing with Section 5000)), the Vehicle Parking District Law of 1943 (Part 1 (commencing with Section 31500) of Division 18), the Parking District Law of 1951 (Part 4 (commencing with Section 35100) of Division 18), the Park and Playground Act of 1909 (Chapter 7 (commencing with Section 38000) of Part 2 of Division 3 of Title 4 of the Government Code), or other works and improvements of a local nature, and may acquire by gift, purchase, or eminent domain proceedings land, rights-of-way, and easements necessary for the works and improvements.

The provisions of the Improvement Act of 1911 relating to conversion of existing overhead electric and communication facilities to underground locations, as set forth in Chapter 28 (commencing with Section 5896.1) of Part 3, Division 7 of this code, excepting Sections 5896.10, 5896.13 and 5896.15, are incorporated in this division as if fully set out herein. References in said Chapter 28 to “this division” shall be deemed to refer to Division 12. The contractor, public utility, public agency or city performing the work of conversion shall be paid therefor from the improvement fund. The agreement provided for by Section 5896.9 shall be made prior to the adoption of the resolution ordering the work. Any written request executed pursuant to Section 5896.14 shall be filed with the clerk not later than the time set for hearing on the report, provided, that the legislative body may authorize such request to be filed at any time not later than the confirmation of the assessment.

The provisions of the Improvement Act of 1911 relating to work performed on a state highway, county road, or railroad right-of-way, as set forth in Sections 5101.7 and 5101.8, are incorporated in this division as if fully set out herein, except that references to “this division” shall be deemed to refer to Division 12 (commencing with Section 10000).

The provisions of Chapter 2 (commencing with Section 5115) of Part 3 of Division 7 of this code providing for the construction of work and the levy of an assessment by a city within a county or by a county within a city, are incorporated in this division as if fully set out herein. Upon obtaining the consent required in that chapter, a city may construct improvements and levy an assessment in a county or in another city, a county may construct improvements and levy an assessment within a city, and a public corporation may consruct improvements and levy an assessment outside of its boundaries either within a city or within a county. If no assessment is to be levied outside the boundaries of the city, county, or public corporation conducting the assessment proceedings, the proposed resolution of intention need not be submitted or approved and the consent required shall be obtained prior to the ordering of the improvement.

When any proceeding is initiated under this division by a legislative body other than that of a city or county, and before the resolution of intention is adopted, the proposed resolution, together with a plat or map which shall indicate by a boundary line the extent of territory included in the proposed district, shall be submitted for approval of the legislative body of the city, where the land to be assessed lies within the corporate limits of any city, or of the county, where the land to be assessed lies within an unincorporated territory. When such approval has been secured, the resolution of intention may be adopted and the legislative body initiating the proceeding may thereafter take each and every step required for or suitable for the consummation of the work and the levying, collecting and enforcement of the assessments to cover the expenses thereof and the issuance and enforcement of bonds to represent unpaid assessments.

As an alternative procedure for constructing any improvement authorized under the Improvement Act of 1911, the legislative body may pass a resolution of intention to do such work, which shall contain a provision that the work shall be instituted when any local, state, or national agency or authority accepts the proposed work as a project for which a contribution of labor, or labor and any portion of materials, supplies, or equipment, will be made by such agency or authority.

Under the alternative procedure the work to be done by the contractor shall consist of furnishing all or any part of the labor, materials, supplies, and equipment necessary for the construction of the improvements or the work may be performed or the labor, materials, supplies, and equipment furnished in the same manner as provided in Chapter 6 of this division. Whenever the alternative procedure is adopted, the resolution shall recite that fact, state the name of the agency or authority which is to make the contribution, the contribution which is to be made, and the work to be done by the contractor or by the city. In all other particulars the resolution shall conform to the provisions of Chapter 3 of this division. Nothing in this section prevents the acceptance of contributions not mentioned in the resolution of intention for any improvements mentioned in this section, and for that purpose Section 5125 is incorporated as part of this division as if fully set out herein.

The provisions of Chapter 26 of Part 3 of Division 7 of this code are incorporated in this division as if fully set out herein. These provisions may be used in combination with the other provisions of this division.

A city may form a maintenance district, in which event Chapter 26 of Part 3 of Division 7 of the Streets and Highways Code, excepting Sections 5850 to 5853, inclusive, as now or hereafter provided, shall hereafter apply. In such event, the officers referred to therein shall be deemed to be the city officers performing the same duties.

Whenever the improvement or acquisition includes the acquiring or the installation of works, appliances, or improvements authorized by this division, and the works, appliances, or improvements are, or may be, under the ownership, management, or control of any public agency other than the city making the acquisition or ordering the work done, or of a regulated public utility, the works, appliances, or improvements may be acquired or installed under the proceedings specified in this division. For purposes of this section and Sections 10110 and 10111, “regulated public utility” includes a cable television company.

Before the ordering of the work, acquisitions, or improvements which are to be owned, managed, or controlled by any other public agency, regulated public utility, or mutual water company, the legislative body shall enter into an agreement with the public agency, public utility, or mutual water company which has, or may have, charge of the works, appliances, or improvements. The agreement may provide for the joint exercise of any power authorized by this division by two or more local agencies authorized to use this division if the legislative body of each participating agency adopts a resolution declaring that the joint agreement would be beneficial to the residents of the area of the agency. A local agency which is a party to the agreement may use the proceeds of any assessment or of any bonds or other indebtedness issued in conjunction with this division pursuant to the agreement to provide facilities which the local agency is otherwise authorized by law to provide, even though another agency which is a party to the agreement does not have the power to provide those facilities. Among other things, the agreement may provide for any of the following:

Any agreement entered into pursuant to this section, to the extent that utilities have been financed by special assessments, shall provide that no main extension refund agreement shall be entered into with a developer.

If an agreement entered into pursuant to Sections 10109 and 10110 provides for the payment of refunds, and to the extent that the works, appliances, or improvements to which the refund payments are applicable are financed by special assessments, any amounts paid by the public agency, public utility, or mutual water company as a refund payment for the works, appliances, or improvements to be transferred to the public agency, public utility, or mutual water company under the agreement shall be deposited into a special fund to be established and administered by the city treasurer and applied as a credit upon the assessment and supplemental assessment, if any, in the same manner as provided in Section 10427.1, or shall be used to call bonds, or both. The credits shall be applied only to the assessments levied for the particular improvements for which the refund is made. Any such amounts shall be transferred to the general fund of the city if either of the following occurs:

After the work, acquisitions or improvements have been completed and accepted, or conveyed to the public agency or utility, title to the works, appliances or improvements so installed, acquired or conveyed shall vest in the public agency or utility and constitute a part of its system, and shall at all times thereafter be used, operated, maintained, and managed by it as a part of such system.

In the case of a proposal for a water supply system or sanitary sewers and facilities, the preliminary steps, including, but not limited to, environmental impact reports, feasibility studies, engineering plans, cost estimates, legal expenses, and elections, may, at the legislative body’s discretion, be deemed to be improvements.
