Kerr County Subdivision Rules & Regs June 26.2006 Page 32 6.04.D. If the Commissioners Court permits a person to revise a subdivision plat, the person shall make the revision by filing for record with the County Clerk a revised plat or part of plat that indicates the changes made to the original plat. 6.04.E. The Commissioners Court is not required to give notice by mail if the plat revision only combines existing tracts. 6.04.F. The revised plat shall be subject to all of the provisions of Kerr County Subdivision Rules and Regulations. [f the revision to the plat revises less than four tracts the alternate platting process set forth in Section 6.035. "Alternate Plat Approval Process for Subdivisions with Less Than Five (5) Lots," may apply. However, the Alternate Plat Approval Process does not change the notice requirements set forth in Section 6.04. 6.04.G. The person requesting the "Revision of Plat" must submit with the request for "Revision of Plat" the names and addresses of all owners of tracts in the subdivision. 6.05 Cancellation of Subdivision: A person owning real property in the county that has been subdivided into lots and blocks or into small subdivisions may apply to the Commissioners Court for permission to cancel all or part of the subdivision, including a dedicated easement or roadway, to reestablish the property as acreage tracts as it existed before the subdivision. If, on the application, it is shown that the cancellation of all or part of the subdivision does not interfere with the established rights of any purchaser who owns any part of the subdivision, or it is shown who owns any part of the subdivision, or it is shown that the purchaser agrees to the cancellation, the Commissioners Court by order shalt authorize the owner of the subdivision to file an instrument canceling the subdivision in whole or in part. The court shall enter the order in its minutes. After the cancellation instrument is filed and recorded in the deed records of the county, the county tax assessor-collector shall assess the property as if it had never been subdivided. 6.OS.A The Commissioners Court shall publish notice of an application for cancellation. The notice must be published in a newspaper, published in the English language, in the county for at least three weeks before the date on which action is taken on the application. The court shall take action on an application at a regular term. The published notice must direct any person who is interested in the property and who wishes to protest the proposed cancellation to appear at the time specified in the notice. The cost of such notice shall be paid for by developer and shall be included in the subdivision permitting fee, see Appendix F. 6.OS.B [f delinquent taxes are owned on the subdivided tract for any preceding year, and if the application to cancel the subdivision is granted as provided by this section, the owner of the tract may pay the delinquent taxes on an acreage basis as if the tract had not been subdivided. For the purpose of assessing the tract for a preceding year, the county tax assessor-collector shall back assess the tract on an acreage basis. Kea County Subdivision Rules & Regs June 26, 2006 Page 33 6.OS.C On application for cancellation of a subdivision or any phase or identifiable part of a subdivision, including a dedicated easement or roadway, by the owners of 75 percent of the property included in the subdivision phase or identifiable part, the Commissioners Court by order shall authorize the cancellation in the manner and after notice and a hearing as provided by Subsections, (A) and (B). However if the owners of at least 10 percent of the property affected by the proposed cancellation file written objections to the cancellation with the court, the grant of an order of cancellation is at the discretion of the court. 6.OS.D To maintain an action to enjoin the cancellation or closing of a roadway or easement in subdivision, a person must own a lot or part of the subdivision that: abuts directly on the part of the roadway, or easement to be canceled or closed; or connected by the part of the roadway or easement to be canceled or closed, by the most direct feasible route, to: a) the nearest remaining public highway, county road, or access road to the public highway or county road; or b) any not canceled common amenity of the subdivision. 6.05.E A person who appears before the Commissioners Court to protest the cancellation of all or part of a subdivision may maintain an action for damages against the person applying for the cancellation and may recover as damages an amount not to exceed the amount of the person's original purchase price for property in the canceled subdivision or part of the subdivision. The person must bring the action within one year after the date of the entry of the Commissioners Court's order granting the cancellation 6.05.E The Commissioners Court may deny a cancellation under this section if the Commissioners Court determines the cancellation will prevent the proposed interconnection of infrastructure to pending or existing development. 6.06 Cancellation of Subdivisions if Land Remains Undeveloped: The Commissioners Court may cancel, after notice and a hearing a subdivision for which the plat was filed and approved before September 1, L989. 6.06.A The Commissioners Court must publish notice of a proposal to cancel a subdivision under this section and the time and place of the required hearing in a newspaper of general circulation in the county for at least 21 days immediately before the date of cancellation order is adopted. The Kerr County Tax Assessor-Collector shall, not later than the 14`b day before the date of the hearing, deposit with the United States Postal Service a similar notice addressed to each owner of land in the subdivision, as determined by the most recent county tax roll. The cost of such notice shall be paid for by developer and shall be included in the subdivision permitting fee, see Appendix F. 6.06.B At the hearing, the Commissioners Court shall permit any interested person to be heard. At the conclusion of the hearing, the court shall adopt an order on whether to cancel the subdivision. The Commissioners Court may adopt an order canceling subdivision if the court determines the cancellation is the best interest of the public. The court may not adopt an order canceling a subdivision if: 1) the cancellation interferes with the established rights of a person who is anon-developer owner and owns any part of the Kerr County Subdivision Rules & Regs June 26, 2006 Page 34 subdivision, unless the person agrees to the cancellation; or 2) the owner of the entire subdivision is able to show that: a) the owner of the subdivision is able to comply with the minimum state standards and model political subdivision rules developed under Section 16343, Water Code, including any bounding requirements; or b) the land developed or improved before September 1, 1989. 6.06.C The Commissioners Court shall file the cancellation order for recording in the deed records. After the cancellation order is files and recorded, the property shall be treated as if it had never been subdivided, and the county chief appraiser shall assess the property accordingly. Any liens against the property shall remain against the property as it was previously subdivided.
