19.20.140 Revision of preliminary plat.
An approved preliminary plat may be revised in one of two ways, depending on the magnitude of the changes proposed.
A. Major Revision. A new preliminary plat hearing is required for major revisions, including changes in primary access points or increases in the number of peak hour vehicle trips, expansions of site area, increases in the number of lots, substantial expansions of environmental impacts or substantive changes to conditions of preliminary approval; provided, that easements established by a dedication cannot be extinguished or altered without the approval of the easement owner or owners, unless the plat or other document creating the dedicated easement provides for an alternative method or methods to extinguish or alter the easement.
B. Minor Revision. An administrative amendment to the prior approval may be applied for if the city planner determines the changes are minor but still within the general scope of the original approval; provided, that easements established by a dedication cannot be extinguished or altered without the approval of the easement owner or owners, unless the plat or other document creating the dedicated easement provides for an alternative method or methods to extinguish or alter the easement. Minor revisions, including phasing of an approved preliminary plat, may be reviewed as an administrative amendment in accordance with the process set forth in AMC 14.04.040. The administrative amendment shall be approved only if all the following criteria are met:
1. The amendment maintains the design intent or purpose of the original proposal;
2. The amendment does not change primary vehicular access points or increase anticipated peak hour vehicle trips;
3. The site area is not expanded and the number of lots is not increased;
4. Circumstances render it impractical, unfeasible or detrimental to the public interests to accomplish the subject condition or requirement of preliminary plat approval;
5. The amendment results in no major adverse environmental or land use impacts on or beyond the site;
6. Portions of an approved preliminary plat may be processed separately for recording in divisions; provided, that all divisions are approved within the prescribed time limits for the preliminary plat; and provided, that the division does not violate the intent of the preliminary plat. When phasing a project, all off-site and on-site mitigation requirements must be completed or bonded commensurate with any impact caused by that particular division of the development. Prior to final approval of a division of the preliminary plat, the city planner shall require an assurance device be submitted for construction of improvements in subsequent divisions if such improvements are necessary for the continuity of transportation, utility, or other systems; and
7. The amendment will be in compliance with the comprehensive plan and applicable laws, ordinances, and regulations. (Ord. 1190-21 § 2 (Exh. A), 2021; Ord. 1016-08 § 2).
