(d) 
Lien Upon Property. A lien upon the property to be subdivided, created by contract between the owner of the property and the City, when the City finds that it is not in the public interest to require installation of the required improvement sooner than two (2) years after the recordation of the map; and/or
(e) 
Other Form of Security. Any other form of security, including security interests in real property, which the Council shall determine to be acceptable.
(Ord. 249 § 3, 1989)
The improvement security shall be provided in the amount determined by the Engineer to cover all of the following:
(a) 
One hundred percent (100%) of the total estimated cost of the improvement or act to be performed;
(b) 
One hundred percent (100%) of the total estimated cost of the improvement or act to be performed securing payment to the contractor, the subcontractors and to persons furnishing labor, materials or equipment to them for the improvement or the performance of the required act;
(c) 
The amount necessary to guarantee or warranty the work for a period of one year following completion or acceptance thereof against any defective work or labor done or defective materials furnished; and
(d) 
An amount sufficient to secure the faithful performance of any changes or alterations in the work, to the extent that such changes or alteration do not exceed ten (10) percent of the original estimated cost of the improvement.
(Ord. 249 § 3, 1989)
In the event that required subdivision improvements are financed and installed pursuant to special assessment or special tax proceedings, the subdivider may apply to the Council for a reduction in the amount of the improvement security required hereunder up to an amount corresponding to the amount of faithful performance and labor and material bonds required by the special assessment or special tax statutes being used. The Council may grant such reduction if it finds that such bonds have been in fact provided and that the obligations secured thereby are substantially equivalent to those required by this Chapter.
(Ord. 249 § 3, 1989)
The improvement security required hereunder shall be released in the following manner:
(a) 
Security given for faithful performance of any act or agreement shall be released upon the final completion and acceptance of the act or work, subject to the provisions of subsection (b)
(b) 
The Council or Planning Director may release a portion of the security in conjunction with the acceptance of the performance of the act or work as it progresses, upon application therefor by the subdivider; provided, however, that no such release shall be for an amount less than thirty percent (30%) of the total improvement security given for faithful performance of the act or work and that the security shall not be reduced to an amount less than ten (10) percent of the total improvement security given for faithful performance, until final completion and acceptance of the act or work. In no event shall the Council or Planning Director authorize a release of the improvement security which would reduce such security to an amount below that required to guarantee the completion of the act or work and any other obligation imposed by this Title, the Subdivision Map Act or the improvement agreement.
(c) 
Security given to secure payment to the contractor, any subcontractors and persons furnishing labor, materials or equipment shall, after passage of the time in which claims of lien are required to be recorded pursuant to article 3 (commencing with section 3114) of Chapter 2 of Title 15 of part 4 of division 3 of the Civil Code and after acceptance of the work, be reduced to an amount not less than the total claimed by all claimants for whom claims of lien have been recorded and notice thereof given in writing to the legislative body. If no such claims have been recorded, the security may be released in full, except an amount reasonably determined by the Council or the Engineer to be required to assure performance of any other obligations secured thereby. The balance of the security shall be released upon the settlement of such claims and obligations for which the security was given.
(d) 
No security given for the guaranty or warranty of work shall be released until the expiration of the period thereof.
(Ord. 249 § 3, 1989)
Upon the failure of the subdivider to complete any improvement, acts or obligations within the time specified, the Council or the Planning Director may, upon notice in writing of not less than ten (10) days, served upon the person responsible for the performance thereof or upon notice in writing of not less than twenty (20) days, served by registered mail addressed to the last-known address of such person, determine that the subdivider is in default and may cause the improvement security or such portion thereof as is necessary to complete the work or act and any other obligations of the subdivider secured thereby to be forfeited to the City.
(Ord. 249 § 3, 1989)
Where an improvement is to be constructed by a public district or other political subdivision, wholly or partly located in the City, and an agreement to that effect is executed by such public or other political subdivision, the subdivider and the City, no bond or cash deposit need be offered to guarantee the performance of such work.
