The community development director or designee may approve lot line adjustments as herein provided. A current preliminary title report shall be required to accompany a lot line adjustment request. This report is required in order to ensure that the properties or portions thereof are not encumbered with liens, delinquent taxes, trust deeds, and/or utility easements on the property which would conflict with the requested lot line adjustment. The community development director shall require that such a conflict be eliminated. In addition, if any of the lots are improved, the community development director shall refer the proposed lot line adjustment to the city engineer for review of possible encroachments.
