(A) General. The preliminary plat and preliminary engineering drawings shall show all proposed phases of development of an area of land under the same ownership. Approval or conditional approval of the concept plan (if required), the preliminary plat and preliminary engineering drawings is required by the Planning and Zoning Commission and City Council prior to consideration of the final plat and final engineering drawings by the Director of Planning and Development. Preliminary plats and preliminary engineering drawings shall be deemed approved if no action is taken by the Planning and Zoning Commission within 30 days of submittal, and if no action is taken by the City Council within 30 days of Planning and Zoning Commission approval.
(B) Changes to preliminary plat. An approved preliminary plat and/or preliminary engineering drawings is binding and must be complied with; however, it may be amended at the request of the developer, or required by the city per this section. Substantial amendments or changes to an approved preliminary plat or preliminary engineering drawings must be reviewed and approved by the Planning and Zoning Commission as well as by the City Council. Minor amendments may be approved by the Planning and Development Director. Minor amendments are those that:
(1) Increase by 10% or less the number of lots or potential structures that can be accommodated by the infrastructure;
(2) Reduce the number of lots; and
(3) Any proposed change in infrastructure is considered a major amendment, unless deemed by the Public Works Director as a minor amendment.
(C) Form and content. A complete submission for approval shall contain ten paper copies of the plat and seven paper copies of the engineering drawings. Failure to submit the plat and engineering drawings together in the quantities as stated herein at the time of submission shall be deemed an incomplete submission. The submission shall not be considered complete until all required documents (plat and engineering documents) in their respective quantities as stated herein are submitted.
(1) Preliminary plat. The preliminary plat shall be prepared and sealed by a Texas Licensed Professional Engineer or Texas Registered Professional Land Surveyor and plotted on 22 inch by 34 inch sheets at a scale of one inch to 100 feet or larger. The plat shall conform to the general requirements and minimum standards of design and requirements, and shall include the following elements as applicable:
(a) A cover sheet is required for all plats involving three or more sheets. All plan sheet numbers shall be placed on the cover along with the corresponding plan sheet titles. This cover sheet should include a listing of all plan sheet numbers and plan sheet titles in the engineering drawings as well. A vicinity map should always be included on the cover sheet to show the project location;
(b) Title block including proposed subdivision name, phase, block and lot numbers, current legal description (or reference thereto), acreage, name and address of property owner, name and address of surveyor/engineer, date of survey, date of preparation and page content title. This title block shall be present on each page of the plat;
(c) Index sheet for plats with more than one sheet that shows the entire subdivision drawn to a scale of not less than one inch equals 100 feet;
(d) Legal description, existing boundary, lot lines and right-of-way lines of streets and easements with accurate dimensions, bearings, deflection angles, radii and central angles of all curves;
(e) Phasing plan if subdivision is to be constructed in phases;
(f) Lot lines shall have line dimensions clearly displayed within the lot along with the lot’s respective lot number. Groups of lots that are considered within a block shall have the block number clearly displayed;
(g) All right-of-way lines and easements shall be clearly displayed on the plat. The plat shall clearly display the location, size and purpose of all existing and proposed easements on or adjoining the property;
(h) Location of existing and proposed streets, alleys, bikeways and sidewalks on or adjoining the site. Such information shall include name, right-of-way widths, type and width of surfacing. All private streets shall be clearly labeled;
(i) Any areas reserved or dedicated for public uses;
(j) Easements and street stub-outs necessary to serve adjacent properties;
(k) Adjacent property information including present ownership, legal descriptions (recorded volume and page) and property lines within 100 feet;
(l) Primary control points or descriptions and ties to such control points to which all dimensions, angles, bearings and similar data shall be referred. The plat shall be located with respect to a corner of the surveyor tract, or an original corner of the original survey of which it is a part. Temporary benchmarks and NGS datum shall be described on each sheet;
(m) Scale, basis of bearing and benchmarks (datum) and description shall all be clearly displayed on the plat; and
(n) A north arrow is required on all sheets and should be oriented either upward or to the right. It is the intent of this requirement that all stationing should start from cardinal points of the compass and proceed in the direction of construction.
(2) Preliminary engineering drawings. Preliminary engineering drawings shall be prepared and sealed by a Texas Licensed Professional Engineer and plotted on 22 inch by 34 inch sheets at a scale of one inch to 100 feet or larger. The preliminary engineering drawings shall match the features found on the preliminary plat and they shall conform to the general requirements and minimum standards of design and requirements in accordance with the most current edition of the Standard Specifications for Public Works Construction, North Central Texas adopted by the city, and shall include the following elements as applicable:
(a) Title block including proposed subdivision name, phase(s), block and lot numbers, current legal description (or reference thereto), acreage, name and address of property owner, name and address of surveyor/engineer, date of survey, date of preparation and page content title. This title block shall be present on each page of the preliminary engineering drawings;
(b) Water layout plan view to include rough locations of service connections, pipe diameters, valves, hydrants and flush assemblies;
(c) Sanitary sewer layout plan to include rough locations of service connections, pipe diameters, cleanouts and manholes;
(d) Street and sidewalk layout plan view; and
(e) Storm water drainage layout plan (drainage calculations are only necessary on major drainage structures at this step).
(D) Processing preliminary plat.
(1) Submission of preliminary plat application along with all items required in § 154.20 (B)(3)(a).
(2) The preliminary plat and preliminary engineering drawings shall be reviewed by the Planning and Development Department for conformity with the city’s plans, thoroughfare plan, utility master plan, engineering standards and specifications, city ordinances and other applicable city standards. Upon completion of this review, the preliminary plat and preliminary engineering drawings shall be submitted to the Planning and Zoning Commission.
(3) The Planning and Zoning Commission shall review the preliminary plat, preliminary engineering drawings and all staff’s recommendations. Particular attention will be given to the arrangement, location and width of streets, their relation to the topography of the land, lot sizes and arrangement, water and sewer lines, drainage, the further development of adjoining lands and the requirements of city ordinances, policies and plans.
(4) The Planning and Zoning Commission shall act on the preliminary plat and preliminary engineering drawings and may advise the developer of any specific changes or additions they will require in the layout, or comment on the character and extent of improvements and dedications that will be required prior to infrastructure construction and as a prerequisite to the approval of the final plat and final engineering drawings.
(5) The Planning and Zoning Commission shall forward the preliminary plat and preliminary engineering drawings with their approval to the City Council for their consideration. The Planning and Development Director shall inform the developer in writing of the decision of the Planning and Zoning Commission and City Council including any conditions for approval or reasons for disapproval. If disapproved by the Planning and Zoning Commission or the City Council, the applicant may resubmit a preliminary plat and preliminary engineering drawings addressing the concerns of the Planning and Zoning Commission and the City Council for reconsideration.
