(4) Except as provided in this subsection, the obligation to pay the unpaid systems development charge and interest thereon shall be secured by a lien against the property upon which development is to occur. Such liens shall arise upon issuance of the permit requiring the system development charge and shall be entered on the city’s lien docket and the debt secured thereby may be collected in the same manner as allowed by law for street improvement assessment liens. In lieu of such lien, upon application of the permittee the obligation to pay the unpaid systems development charge and interest thereon may be secured by property, bond, deposits, letter of credit or other security acceptable to the city manager or the manager’s designee.

No portion of the administrative charge will be refunded, and additional review fees may be imposed to cover the cost of calculating and processing the partial refund.

(7) The SDC methodology adopted under section 7.710 of this code may require that a proposed development be reviewed by the city in order to determine whether the proposed development will result in an increase in the usage of any capital improvement or will create the need for additional capital improvements. Development that will have such an impact will be charged SDCs and associated administrative charges. If this review determines that the development will not have such an impact, then only a review fee may be imposed for this review.
