A division of a tract under this subsection includes a division regardless of whether it is made by using a metes and bounds description in a deed of conveyance or by using any other method. B. Divisions Not Requiring Approval. The following divisions do not require approval by the Town of Westlake; however, the Town shall not extend utilities, provide access to public roads or issue building permits for the development of any property which has not received final plat approval, unless expressly provided by this ordinance to the contrary. 1. Leaseholds on a Commercial Building Site. The creation of a leasehold for a space within a multi -occupant building or for a commercial building site which does not abut a public street, or the division for property into such leaseholds, provided that the property is a part of an approved subdivision or addition and regulated in accordance with the site plan requirements of the Town, and such plat has been amended as may be required to add easements or otherwise serve the leasehold. For purposes of this section, a leasehold abuts a public street if it is immediately adjacent to a public street or if it is so close to a public street that no usable property lies between the leasehold and the public street. 2. Agricultural Leaseholds. The creation of a leasehold for agricultural use of the subject property, provided that the use does not involve the construction of a building(s) to be used as a residence or for any purpose not directly related to agricultural use of the land or crops or livestock raised thereon. 3. Division Through Inheritance or Court of Law. The division of property through inheritance, the probate of an estate, or by a court of law and not for purposes of development. 4. Conveyances by Metes and Bounds. The division of land into two or more parts, where all the part are larger than 20 acres. C. Exemptions from Subdivision Requirements. The owner of a tract of land located within the limits or in the extraterritorial jurisdiction of the Town of Westlake who proposes to develop that tract, and who claims an exemption from the Town's subdivision regulations not expressly authorized under this section, including requirements to replat, or who proposes Subdivision Ordinance Section 7 General Provisions Page 2 to divide such tract into parcels or lots each of which is greater than five (5) acres in size, and for which no public improvement is to be dedicated, or who proposes to develop such tract for which the only access is a private easement or private street, must obtain approval of a development plat pursuant under this ordinance prior to commencement of development, and prior to issuance of any building permit or the connection of any utility. 1. Development. For purposes of this section, the term "development" means the construction of any building, structure or improvement of any nature, or the enlargement of any external dimension thereof. 2. Plats Approved, or Applied for Prior to This Ordinance. No development plat shall be required, where the land to be developed or divided has received final plat approval under the Town's subdivision regulations prior to the effective date of this ordinance, or for which an application for preliminary or final plat approval for such land is pending or is submitted. 3. Other Exemptions. The Board of Aldermen may, from time to time, exempt development or land divisions from the requirements of this section. D. Information on When a Plat Is Required. A written request may be directed to the Town Engineer for information concerning whether a plat is required under these regulations, in accordance with Section 212.0115, as amended, of the Texas Local Government Code. E. Exclusion of Platting Requirements Does Not Waive Town Jurisdiction. The exclusion of any activities from these regulations does not waive any jurisdiction the Town now exercises or may exercise over those matters. F. No Subdivision Other Than By Town Approved Plat. Unless no plat approval is required by these regulations, no land may be subdivided or platted through the use of any legal description other than with reference to a plat approved by the Board of Aldermen in accordance with these regulations. G. No Land Sales, Leases or Transfers Without A Plat. Except (a) as provided above and (b) lots of record established prior to the effective date of this ordinance, no land shall be sold, leased, or transferred until the property owner has obtained approval of a final plat, development plat or conveyance plat as required by these regulations. H. Town Shall Withhold Services On Lots Not Officially Platted. The Town shall withhold all public improvements and utilities, including the maintenance of streets and the provision of wastewater facilities and water service, from all tracts, lots or additions, the platting of which has not been officially approved and for which a certificate of compliance has not been issued pursuant to Subsection 3.3 of this Article.

No building permit or certificate of occupancy shall be issued for any parcel or tract of land until the property has received final plat or development plat approval, and no private improvements shall take place or be commenced except in conformity with these regulations. 1.4 Interpretation, Conflict and Separability A. Interpretation. In their interpretation and application, the provisions of these regulations shall be held to be the minimum requirements for the promotion of the public health, safety and general welfare. These regulations shall be construed broadly to promote the purposes for which they are adopted. B. Conflict with Other Laws. These regulations are not intended to interfere with, abrogate, or annul any other ordinance, rule or regulation, statute or other provision of law except as provided in these regulations. Where any provision of these regulations imposes restrictions different from those imposed by any other provision of these regulations, or other provision of law, the provision which is more restrictive or imposes higher standards shall control. C. Separability. If any part or provision of these regulations or the application of these regulations to any person or circumstances is adjudged invalid by its operation to the part, provision, or application directly involved in the controversy in which the judgment shall be rendered and it shall not affect or impair the validity of the remainder of these regulations or the application of them to other persons or circumstances. The Board of Aldermen hereby declares that it would have enacted the remainder of these regulations even without the part, provision, or application which is judged to be invalid. 1.5 Amendment to Subdivision Regulations For the purpose of protecting the public health, safety and general welfare, the Town Engineer, the Town Planner, the Planning and Zoning Commission or the Board of Aldermen may from time to time propose amendments to these regulations which shall from time to time propose amendments to these regulations which shall then be approved or disapproved by the Board of Aldermen at a public hearing. 1.6 Effect on Pending Plats All applications for plat approval, including final plats, pending on the effective date of these regulations and which have not lapsed shall be reviewed under regulations in effect immediately preceding the date of adoption of these regulations. 1.7 Filing Fees Subdivision Ordinance Section 1 General Provisions Page 4 A schedule of filing fees for the Town of Westlake may be obtained from the Town Secretary or Town Engineer and may be found in the adopted fee schedule.

Before any land is platted, the property owner must apply for and secure approval of the proposed subdivision plat or addition plat in accordance with the following procedures, unless otherwise provided by these regulations. Subdivisions are classified as major or minor depending on the number of lots proposed and the extent of public improvements required. 2. Minor Plats. A minor plat must involve four or fewer lots fronting on an existing street and does not require the creation of any new street. A minor plat may follow a one step process and be approved by the Town Engineer; however, the Engineer may elect to follow the procedure for a major plat. 3. Major Plats. All plats not considered a minor plat, will be considered major plats and must follow the two step process—first securing preliminary plat approval, and then obtaining final plat approval. B. Retail, Office Park, and Industrial Park Subdivision. A retail, office park, or industrial park subdivision shall be processed for approval in the same manner as provided for a residential subdivision except that no individual lots need to be shown on the plat and only streets, blocks, easements and minimum building lines need be indicated. 2.2 Coordination with Planned Residential Developments A. Land With Approved or Pending Application for Concept Plan or Development Plan. No application for a subdivision plat or development plat shall be approved on land for which there is an approved or pending application for a concept plan or development plan, unless the plat is consistent with the standards for planned residential developments contained in the Town of Westlake Unified Development Code. B. Preliminary Subdivision Plat With Site Plan Approval. A preliminary subdivision plat shall be submitted with the application for approval of a site plan if the property has not already been subdivided in a manner to accommodate the development 2.3 Statutory Procedure A. Official Submission Date. For the purpose of these regulations, the date on which an application for approval of a final plat containing all required elements mandated by the Tex. Loc. Gov't Code Section 212.004(b), is first filed with the Town Secretary shall Subdivision Ordinance Section 2 Platting Procedure Page 6 constitute the official submission date for the plat, after which the statutory period required for approval or disapproval of the plat shall commence to run. No application shall be deemed filed until (a) all required filing fees are paid and (b) the Town Engineer determines that the application is complete. Failure by the Town Engineer to make a determination of completeness within ten (10) working days of the date of submission shall result in the application being deemed complete. B. Compliance Procedure for Minor Plats.

E. Approval Procedures. 1. Planning and Zoning Commission Decisions. Following review of the Preliminary Plat and other materials submitted for conformity thereof to these regulations, the Commission shall recommend only approval as submitted, approval with conditions or denial of the submitted plat. a) Recommended Approval. Preliminary plats recommended for approval or conditional approval shall be filed for hearing by the Board of Aldermen. b) Recommended Denial. Preliminary Plats not recommended for approval may be processed, at the option of the applicant, in one (1) of the two (2) following ways: 1) Preliminary Plat may be revised in accordance with the recommendations of the Planning and Zoning Commission and refiled for reconsideration at a regularly scheduled Planning and Zoning Commission meeting; or 2) The Preliminary Plat recommended for denial may be filed for hearing at a regularly scheduled Board of Aldermen meeting. 2. Recording of Commission Action. The action of the Planning and Zoning Commission shall be noted on two (2) copies of the Preliminary Plat, referenced and attached to any conditions determined. One (1) copy shall be returned to the subdivider or developer and the other retained in the files of the Town staff. A notation of the action taken on each Preliminary Plat and requisite reasons therefor shall be entered in the minutes of the Planning and Zoning Commission. 3. Forward Preliminary Plat to Board. The Town Engineer shall submit the Preliminary Plat with the recommendations established by the Planning and Zoning Commission to the Board of Aldermen for their consideration, with a copy provided to the applicant. Seven (7) additional copies of the Preliminary Plat should be submitted to the Board of Aldermen through the Town Engineer not less than fifteen (15) days prior to the Board of Aldermen meeting at which consideration is desired. Subdivision Ordinance Section 2 Platting Procedure Page 11 4. Board Consideration of Preliminary Plat. After review of the preliminary plat, any and all reports and recommendations as submitted pursuant to these regulations, and any exhibits submitted at the public hearing, the Board of Aldermen shall approve or deny the preliminary plat. The action of the Board shall be noted on two (2)copies of the preliminary plat. One (1) copy shall be returned to the subdivider or developer and the other retained in the Town files. F. Effect of Decision. Approval of a preliminary plat by the Board of Aldermen constitutes authorization for the Town Engineer to release construction plans following his/her review and final approval. Approval of a preliminary plat also authorizes the property owner, upon fulfillment of all requirements and conditions of approval, to submit an application for final plat approval. Conditional approval of the preliminary plat by the Board, however, shall not constitute approval of the final plat. Upon release of the construction plans, the Town Engineer shall issue a certificate indicating the construction plans have been released and construction of the public improvements are thereafter authorized and that grading by the property owner may commence. Additional certificates may be issued by the Town Engineer authorizing the construction of private utilities or facilities on a phased schedule, subject to permit standards otherwise applicable. G. Amendments to Preliminary Plat. 1. Major and Minor Amendments. At any time following the approval of a preliminary plat, and before lapse of the approval, a property owner may request an amendment to the approved preliminary plat. The requested amendment shall be classified as a major amendment or minor amendment according to the following criteria: a) Major amendments include the rerouting of streets, addition or deletion of alleys, or addition or deletion of more than 10% of the approved number of lots. b) Minor amendments include the adjustment of street and alley alignments, lengths, and paving details, the addition or deletion of lots within 10% of the approved number, and the adjustment of lot lines. The Town Engineer may approve or disapprove a minor amendment. Disapproval may be appealed to the Board of Aldermen. Major amendments may be approved by the Board at a public meeting in accordance with the same requirements for the approval of a preliminary plat. 2. Approval of Amendments. The Commission shall recommend and the Council shall approve, conditionally approve or disapprove any proposed major amendment and may make any modifications in the terms and conditions of preliminary plat approval reasonably related to the proposed amendment. Subdivision Ordinance Section 2 Platting Procedure Page 12 3. Retaining Previous Approval. If the applicant is unwilling to accept the proposed amendment under the terms and conditions required by the Town, the applicant may withdraw the proposed amendment and the project as originally submitted will retain the previous approval. H. Lapse of Approval, Extension and Reinstatement Procedure. 1. Lapse of Preliminary Plat Approval. A preliminary plat expires two years from the date of approval, and such plat shall be null and void thereafter, unless a final plat application for the area depicted in the preliminary plat has been filed with the City or an extension has been requested within the two-year period. Thereafter, the applicant shall be required to submit a new plat subject to the then existing subdivision regulations. 2. Petition for Extension or Reinstatement of Approval. Prior to the lapse of approval for preliminary plat, as provided in these regulations, the property owner may petition the Board to extend or reinstate the approval. The petition shall be considered at a public meeting of the Board. 3. Decision by the Commission. In determining whether to grant the request, the Board shall take into account the reasons for lapse, the ability of the property owner to comply with any conditions attached to the original approval and the extent to which newly adopted subdivision regulations shall apply to the plat or study. The Board shall either extend or reinstate the plat, or it shall deny the request, in which instance the property owner must submit a new application for approval. 4. Length of Time for Extended or Reinstated Plat. The Board may specify a shorter time for lapse of the extended or reinstated plat than is applicable to original approvals. 2.6 Procedure for Final Plat Approval A. Purpose and Applicability. 1. Purpose. The purpose of a final plat is to enable recording of the subdivision of property that includes the elements specified in Tex. Loc. Gov't Code, Section 212.004 and which complies with the requirements of Section 212.010. 2. Applicability. A final plat shall be required for all subdivisions of property provided for in Tex. Loc. Gov't Code, Section 212.004. B. Timing of Public Improvements. 1. Public Improvements Prior to Signing Plat. The Board may require that all public improvements be constructed, offered for dedication and accepted by the Town prior to the signing of the final plat. The Board may permit the deferral of the construction of public improvements if in its judgment, deferring the construction would not result in any harm to the public, or would offer significant advantage in coordinating the site's Subdivision Ordinance Section 2 Platting Procedure Page 13 development with adjacent properties and off-site public improvements. Any required public improvement(s) approved for deferred construction must be provided for as required in Section 3 prior to approval of the final plat. 2. If Public Improvements Are Not Completed. If the Board does not require that all public improvements be installed, offered for dedication and accepted by the Town prior to signing of the final plat by the Mayor, it shall require the applicant to execute a subdivision improvement agreement and provide security for the agreement as provided in Subsection 3.1. 3. Where No Preliminary Plat is Required. This procedure shall also apply to the approval of a final plat if the preliminary plat is not required. C. Submittal Requirements. Eight (8) copies of the final plat, together with a reproducible mylar drawing, a computer file of the final plat on media as specified by the Town Engineer in either AutoCad or DXF format, and three (3) sets of engineering plans shall be submitted to the Town Engineer at least fifteen (15) days prior to the meeting at which consideration is desired. This plat shall be submitted at a scale of one hundred (100) feet to one (1) inch (for small subdivisions, at a scale of fifty feet to one inch) and the final plat shall show or be accompanied by the following information: 1. The name of the owner and/or subdivider and of the surveyor responsible for the plat and the following language: Notice: Selling a portion of this addition by metes and bounds is a violation of the Town Ordinance and state law and is subject to fines and withholding of utilities and building permits. 2. The name of the subdivision and adjacent subdivisions, the names of streets (to conform wherever possible to existing street names) and number of lots and blocks, in accordance with a systematic arrangement. 3. An accurate boundary survey of the property, with bearings and distances, referenced to survey lines and established subdivisions, and showing the lines of adjacent lands and the lines of adjacent streets, with their width and names. Street and lot lines in adjacent subdivisions shall be shown in dashed lines. 4.

The amount of the escrow shall be determined by using the average of the comparable bids awarded by the Town in the preceding six (6) months or, if none exist, then current market value of construction as determined by an estimate by the Town Engineer. The determination shall be made as of the time the escrow is due. D. Termination of Escrow. Escrows which have been placed with the Town under this Section which have been held for a period of ten (10) years from the date of the payment or agreement, and in the event that the Town has not authorized the preparation of plans and specifications for construction of such roadway facilities for which the escrow was made, shall upon written request be returned to the record property owner, with accrued interest, as limited by Subsection 16.5 F. Such return does not remove any obligations of the owner for construction of the required facilities if Subdivision Ordinance Section 16 Participation Policies FEW64 a building permit has not been issued on the subject lot or if a new building permit is applied for. E. Refund. If any public improvement for which escrow is deposited, is constructed, or is reconstructed by another governmental authority at no cost to the Town, the escrow funds and accrued interest shall be refunded to the property owner or developer after completion and acceptance of the public improvements. In the event that a portion of the cost is borne by the Town and the other portion of the cost by another governmental authority, the difference between the owner's actual proportionate cost and the escrow funds, including accrued interest, if any, shall be refunded after completion and acceptance of the improvements. F. Interest Limitation. If money is refunded within six months of deposit, only the principal will be refunded. Monies returned after this date will be refunded with interest accrued, calculated at 1% less than the rate of actual earnings. Subdivision Ordinance Page 66 Section 16 Participation Policies
