If the legislative body finds, after taking the steps provided by Sections 2821, 2822 and 2823, that the probable assessments will not exceed the limitations set up by this division, it may cause the clerk to mail prepaid postcards giving notice of its findings and proposed action. Each such notice shall have attached thereto an addressed reply postcard with the return postage thereon guaranteed.

The cards shall be mailed to each person to whom land in the proposed assessment district is assessed on the last equalized county assessment roll available on the date the report is commenced, at his address as shown upon such roll and to

any person whether owner in fee or having a lien upon or legal or equitable interest in any land within the proposed district who has filed with the clerk his name and address and the designation of the land in which he is interested.

The notice of proposed assessment shall be substantially in the following form (filling in the blanks):

NOTICE OF PROPOSED ASSESSMENT

Notice is hereby given that the (name of the legislative body) proposes to adopt a resolution of intention under the (here mention statute under which it proposes to proceed) covering (here state in general terms what acquisitions and/or improvements are to be made). Your land will be assessed to pay a part of the cost thereof. This questionnaire is sent to the property owners interested to ascertain whether or not the owners of as much as 15 per

cent of the area of the proposed district demand proceeding under the “Special Assessment Investigation, Limitation and Majority Protest Act of 1931.” Under said investigation act information will be obtained and a report thereon made, open to public inspection, and stating among other things (1) the estimated cost of the proposed project; (2) the estimated amount of existing assessments upon each parcel of land in the district; (3) the estimated assessment upon your lands for the proposed project. In the event that you desire the proceeding under said investigation act, so indicate on the attached card and return the same to the clerk within 30 days from (here set forth the date, not earlier than one day subsequent to the mailing of the cards). Sign your name legibly and describe or designate the property owned by you.

Instruction: If you are in favor of the improvement without the investigation report strike out the word “does.” If you desire the investigation

report, whether or not you desire the improvement, strike out the words “does not.”

If any parcel of land in the assessment district is assessed as owner unknown on the county assessment roll, no notice need be sent for such parcel unless the name and address of the person claiming an interest in that property is filed with the clerk, in which case notice shall be mailed to such person and address.

In the absence of fraud no error in the mailing of the notices, and no failure of any person to receive the notices shall in any way affect the validity of the proceedings, but the clerk shall file an affidavit of mailing such notices and shall include therein a list of the names and addresses of the person to whom such notices were sent.

The return postcards shall be filed in the clerk’s office and after the expiration of the 30-day period specified in the Notice of Proposed Assessment all demands for the investigation made to the legislative body shall be computed and it shall by order entered on its minutes determine whether or not the owners of 15 per cent of the area of the proposed assessment district have demanded such investigation. Such determination shall be final and conclusive in the absence of actual fraud.

If the owners (as defined in the law under which it is proposed to proceed) of 15 per cent of the area of the proposed assessment district do not so demand the making of the investigation provided by this division, the legislative body shall be at full liberty to proceed under the statute under which it has declared its intention to carry through the contemplated proceedings without any further restrictions whatsoever by reason of the terms or provisions of this division except that the majority protest provisions of this division shall apply.

If the owners of 15 per cent or more of the area of the proposed district so demand the making of such investigation, all provisions of this division shall apply to the proposed proceeding, if any further steps are taken therein by the legislative body.
