SEC. 51A-8.401. WHEN PLATTING IS REQUIRED.

Platting is required:
   (a)   To create a building site. Platting is required to create a building site pursuant to Section 51A-4.601(a)(1) of this chapter.
   (b)   To subdivide land. Platting is required to divide a lot or tract into two or more parcels for development of the parcels. Pursuant to the authority granted by Section 212.0045 of the Local Government Code to provide exceptions to state law platting requirements, the city of Dallas shall not require platting to divide property for transfer of ownership through a metes and bounds description unless and until a building permit is requested for the property to be developed as a separate building site. Unless a separate building site has otherwise been established as provided in Section 51A-4.601, a conveyance of property accomplished through a metes and bounds description without platting will not be recognized as a separate building site, nor will the lines of ownership be recognized for purposes of determining development rights on the parcel conveyed without platting.
   (c)   To combine lots or tracts. Platting is required to combine two or more lots or tracts into one lot.
   (d)   To amend a plat. Platting is required if property is to be developed in a manner inconsistent with an existing plat.
   (e)   To include vacated and abandoned property. Platting is required to incorporate property that has been vacated or abandoned into a legal building site.
   (f)   To correct errors. Platting is required to correct an error on an approved and recorded plat.
   (g)   To develop a planned development district. A preliminary plat must be submitted at the same time as the development plan for a planned development district. The subdivision administrator and the director shall coordinate the commission review of the preliminary plat and the development plan in accordance with Section 51A-4.702. (NOTE: If the property included in a development plan application has been previously platted or a building site otherwise exists under Section 51A-4.601, this requirement does not apply.)
   (h)   To establish a shared access development. Platting is required to establish a shared access development as provided in Section 51A-4.411. (Ord. Nos. 20092; 23384; 24270; 24731; 24843)

SEC. 51A-8.402. PLATTING OF STREET RIGHT-OF-WAY PROHIBITED.

   Platting street right-of-way without platting adjacent property to be served by the street is prohibited unless the director of development services and the chief planning officer recommend platting the right-of-way because a graphic representation of the right-of-way is needed to facilitate thoroughfare or local street planning. (Ord. Nos. 20092; 22026; 23384; 28424; 29478; 32002)

If the subdivision administrator determines that the application is complete, the subdivision administrator shall accept it and route it to all affected departments. If the subdivision administrator determines that the application is incomplete, the subdivision administrator shall return it to the applicant with a description of its deficiencies. If the subdivision administrator determines that the resubmitted plat contains changes that are not required to address the commission's reasons for disapproval, the subdivision administrator shall reject the application and the applicant must submit a new preliminary plat application. The resubmitted plat application must be submitted with all required fees and contain the following unless the subdivision administrator determines that an item listed is not applicable and may be omitted:
         (A)   A copy of the previously disapproved preliminary plat.

      (2)   Staff review.
         (A)   All affected departments shall review the initial preliminary plat application and forward their comments, in writing, to the subdivision administrator within 14 days after the date a complete application is received. (Holiday scheduling may require an extension of the review period.) The subdivision administrator shall formulate a staff recommendation from the comments received in the interdepartmental review process, and submit the initial plat application to the commission within 30 days after the date a complete application is accepted by the city (unless it is an approved administrative plat and the applicant does not appeal any of the conditions). The subdivision administrator shall formulate a staff recommendation and forward a preliminary plat application that has been resubmitted under Subsection (a)(1.1) of this section to the commission with 15 days after the date a complete application is accepted by the city. If the staff recommendation is for disapproval of the application, the subdivision administrator must provide the reasons for disapproval to the commission.
         (B)   The subdivision administrator shall approve an administrative plat within 18 days after the date a complete application is accepted by the city if the subdivision administrator finds that it complies with the policies and purposes of this article.

The subdivision administrator shall provide reasons for refusing to approve the plat to the commission.
         (C)   An applicant may appeal staff recommendations on an administrative plat or on any other plat to the subdivision review committee of the commission before the plat is considered by the commission, provided the request for appeal is made in sufficient time to allow staff and commission compliance with the 30-day action requirement and applicable posting and notice requirements.
         (D)   If, after city staff or commission review, it is determined that a minor plat does not comply with the minor plat definition, the application must be considered as a preliminary plat. The increase in fee must be paid before the application is processed.
         (E)   If, after city staff review, it is determined that an administrative plat does not comply with the administrative plat definition, if city staff refuses to approve an administrative plat, if the applicant appeals any administrative plat conditions, or if the subdivision administrator refers the plat to the commission, the application must be considered as a preliminary plat.
      (3)   Commission action.
         (A)   Initial application. The commission must hold a public hearing for all replats, and act upon all plat applications, other than approved administrative plats where the conditions are not appealed, within 30 days after the date a complete application is accepted by the city. The commission shall approve the application if it finds that it complies with the policies and purposes of this article. If the commission disapproves an application, the reasons for disapproval must be stated in the motion for disapproval, along with a citation to the relevant section of the Dallas City Code or state or federal law.
         (B)   Resubmission application. If the commission disapproves a plat application under Subparagraph (A), the applicant may file a resubmission application to correct the reasons for disapproval. The commission must hold a public hearing on all resubmitted applications within 15 days after the date a complete resubmission application is accepted by the city.

      (4)   Effect of preliminary plat approval and effective period.
         (A)   Approval of a preliminary plat by the commission or the subdivision administrator is not final approval of the plat, but is an expression of approval of the layout shown subject to satisfaction of specified conditions.

         (B)   All plats other than certificates of correction must be submitted for final staff review and approval by the subdivision administrator in the form of a final plat, except that the subdivision administrator may provide a certificate of approval for an administrative plat in accordance with Paragraph (8).
         (C)   If the perimeter boundary or any layout design element changes, or if, in the opinion of the subdivision administrator, any other feature or condition changes, the plat must be considered again as a preliminary plat by the commission or the subdivision administrator in the case of an administrative plat. If a replat must be considered again by the commission under this paragraph, new notices must be issued for a residential replat, and a new public hearing must be held.
         (D)   Except as provided in this subparagraph, a preliminary plat approved by the commission expires five years after the commission action date approving the plat if no progress has been made toward completion of the project in accordance with Texas Local Government Code Section 245.005. An approved minor plat, amending plat (minor), or an administrative plat expires two years after the commission action date approving the plat or within two years after the date of the subdivision administrator’s action letter approving the administrative plat if no progress has been made toward completion of the project in accordance with Texas Local Government Code Section 245.005.
      (5)   Action letter.
         (A)   Commission-approved plats. Within seven days after the commission action date, the subdivision administrator shall send an action letter to the applicant. If the commission disapproved the application, the letter must contain the reasons for disapproval. If the commission approved the application, the letter must contain all conditions of approval. The letter must contain a citation to the relevant section of the Dallas City Code or state or federal law for each reason for disapproval or condition of approval.

      (6)   Satisfaction of conditions required. The subdivision administrator shall endorse the administrative plat or submit the plat for endorsement pursuant to Paragraph (8) as soon as the owner has complied with the following requirements: (Any proposed change to a preliminary plat condition must be resubmitted to the commission as a preliminary plat.)

         (F)   For a plat that includes dedication of any streets or alleys, the lienholder must provide a letter of consent subordinating the lienholder’s interest to the dedicated area, and if the owner has a title insurance policy for the platted area, the policy must be updated to within ninety days prior to the date the plat is signed by the commission chair. This provision does not apply to a residential replat that meets the criteria set forth for a minor plat.
         (G)   All plats other than minor plats must be provided to the chief city surveyor in an electronic format approved by the geographic information systems section of the department of development services.
      (7)   Appeal.
         (A)   Adverse decisions of the subdivision administrator regarding whether a preliminary plat condition has been satisfied may be appealed to the subdivision review committee by the applicant or by the owners, as ownership appears on the last approved ad valorem tax roll, of all lots that are:
            (i)   within the original subdivision; or
            (ii)   in single-family or duplex districts and within 200 feet of the lot or lots for which the replat is requested.
The appeal must be made in writing on a form furnished by the subdivision administrator.
         (B)   The subdivision review committee shall render a final decision on the appeal within 21 days after the date a complete application for an appeal is made.
         (C)   The decision of the subdivision review committee is final unless appealed by the applicant to the commission within 7 days after the date a final decision is made.
      (8)   Certificate of approval.
         (A)   Commission-approved plats. If the subdivision administrator determines that the applicant has satisfied all the conditions and requirements of Paragraph (6), the administrator shall immediately forward the final plat to the chair of the commission, who shall endorse the final plat with a certificate indicating approval of the plat. The secretary of the commission shall attest the signature of the chair on the certificate of approval and shall, within five working days, give notice to the applicant that the certificate of approval has been signed. Notice is given by depositing the notice properly addressed and postage paid in the United States mail. The notice must be sent to the address shown on the application.
         (B)   Administrative plats. If the subdivision administrator determines that the applicant has satisfied all the conditions and requirements of Paragraph (6), the administrator shall endorse the final plat with a certificate indicating approval of the plat. A notary public shall attest the signature of the administrator on the certificate of approval and the subdivision administrator shall, within five working days, give notice to the applicant that the certificate of approval has been signed. Notice is given by depositing the notice properly addressed and postage paid in the United States mail. The notice must be sent to the address shown on the application.
      (9)   Final plat.
         (A)   Commission-approved plats. A final plat may be submitted only after the commission action letter regarding the preliminary plat has been received by the applicant. If engineering plans are required as a condition of approval of a preliminary plat, the final plat cannot be submitted until all engineering plans have been approved in accordance with Section 51A-8.404, to avoid the necessity of multiple submissions. All staff comments shall be forwarded to the subdivision administrator within 21 days of the routing date of the final plat. The director shall notify the applicant of the results of the review. If further modifications are required, the director may require additional submissions of the final plat and fees in accordance with the fee schedule.
         (B)   Administrative plats. A final plat may be submitted only after the subdivision administrator action letter regarding the administrative plat has been received by the applicant. All staff comments shall be forwarded to the subdivision administrator within 13 days after the final plat is submitted. The subdivision administrator shall notify the applicant of the results of the review. If further modifications are required, the subdivision administrator may require additional submissions of the final plat and fees in accordance with the fee schedule.
      (10)   Phasing of final plats. After a preliminary plat has been approved by the commission, a final plat may be submitted that includes less than all of the area shown in a preliminary plat if:
         (A)   the proposed phase conforms to the approved preliminary plat;
         (B)   the proposed phase meets all conditions of approval of the preliminary plat;
         (C)   the proposed phase provides a logical progression of development;
         (D)   the proposed phase being submitted could function as an independent development even if no other phases were ever submitted or approved;
         (E)   enough area remains outside the phase, but within the boundaries of the preliminary plat, to independently satisfy the minimum zoning requirements of the property;
         (F)   the area outside the phase has at least the minimum frontage required; and
         (G)   all fees have been paid in accordance with the fee schedule.
   (b)   Replatting.
      (1)   Replatting without vacating preceding plat. A replat of a subdivision or part of a subdivision that does not meet the amending plat (minor) criteria in Subsection 51A-8.403(c)(1)(A) and (B) may be recorded and is controlling without vacating the preceding plat if the replat:
         (A)   is signed and acknowledged by the owners of the property being replatted;
         (B)   is approved after a public hearing on the matter by the commission;
         (C)   does not amend or remove any covenants or restrictions; and
         (D)   meets all requirements of the plat approval process in Subsection (a).
      (2)   Residential replat. In addition to compliance with Paragraph (1), a residential replat without vacating the preceding plat must comply with the requirements of this subsection if:
         (A)   during the preceding five years, any of the area to be replatted was limited by an interim or permanent zoning classification to residential use for not more than two residential units per lot; or
         (B)   any lot in the preceding plat was limited by deed restrictions to residential use for not more than two residential units per lot.
      (3)   Notice and protest for a residential replat.
         (A)   Notice. Before the 15th day before the date of the public hearing, notice of the required public hearing on a replat must be:
            (i)   published in an official newspaper or a newspaper of general circulation in the county in which the municipality is located; and
            (ii)   mailed, along with a copy of the required provisions of state law, to the owners, as ownership appears on the last approved ad valorem tax roll, of all lots that are within 200 feet of the lot or lots for which the replat is requested, and are:
               (aa)   within the original subdivision;
               (bb)   in single-family, town-house, or duplex districts; or
               (cc)   shown on the zoning map to be restricted to single-family, townhouse, or duplex use.
         (B)   Protest.
            (i)   In general. If the proposed replat requires a variance and the owners of at least 20 percent of the area of the lots or land immediately adjoining the area covered by the proposed replat and extending 200 feet from that area, but within the original subdivision, protest the replat in accordance with state law, the commission may approve the proposed plat only upon the affirmative vote of at least three-fourths of the members present of the commission. A protest must be filed with the commission before the close of the public hearing at which the plat is to be considered.
            (ii)   Form of protest. A protest must be in writing and, at a minimum, contain the following information:
               (aa)   A description of the property at issue by address or lot number.
               (bb)   The names of all persons protesting the proposed replat.
               (cc)   A description of the area of lots or land owned by the protesting parties that is immediately adjoining the area covered by the proposed replat and extending 200 feet from that area, but within the original subdivision.
               (dd)   The mailing addresses of all persons signing the protest.
               (ee)   The date and time of its execution.
               (ff)   The protest must bear the original signatures of all persons required to sign under this paragraph.
         (C)   Who must sign.
            (i)   A protest must be signed by the owner of the property in question, or by a person authorized by power of attorney to sign the protest on behalf of the owner. If the property is owned by two or more persons, the protest must be signed by a majority of the owners, or by a person authorized by power of attorney to sign the protest on behalf of a majority of the owners, except that in the case of community property, the city shall presume the written protest of one spouse to be the protest of both.
            (ii)   In the case of property owned by a corporation, the protest must be signed by the president, a vice president, or by an attorney in fact authorized to sign the protest on behalf of the corporation. In the case of property owned by a general or limited partnership, the protest must be signed by a general partner or by an attorney in fact authorized to sign the protest on behalf of the partnership.
            (iii)   Lots or land subject to a condominium regime are presumed to be commonly owned in undivided interests by the owners of all condominium units and under the control of the governing body of the condominium. For such lots or land to be included in calculating the lots or land area protesting a replat, the written protest must state that the governing body of the condominium has authorized a protest in accordance with procedures required by its bylaws, and that the person signing the protest is authorized to act on behalf of the governing body of the condominium. A written protest signed by the owner of an individual condominium unit shall not be accepted unless the filing party produces legal documents governing the condominium which clearly establish the right of an individual owner to act with respect to his or her respective undivided interest in the common elements of the condominium.
         (D)   When signatures must be acknowledged.
            (i)   Except as otherwise provided in this subparagraph, all signatures on a written protest must be acknowledged before a notary public.
            (ii)   A signature on an original reply form sent by the city to the mailing address of the property owner need not be acknowledged.
            (iii)   A signature on a protest delivered in person by the person signing need not be acknowledged if its reliability is otherwise established to the satisfaction of the subdivision administrator. In such a case, a summary of the evidence of reliability considered by the subdivision administrator must be endorsed on the protest by the subdivision administrator.
         (E)   Presumptions of validity.
            (i)   In all cases where a protest has been properly signed pursuant to this paragraph, the city shall presume that the signatures appearing on the protest are authentic and that the persons or officers whose signatures appear on the protest are either owners of the property or authorized to sign on behalf of one or more owners as represented.
            (ii)   In cases of multiple ownership, the city shall presume that a properly signed protest, which on its face purports to represent a majority of the property owners, does in fact represent a majority of the property owners.
            (iii)   The presumptions in this subparagraph are rebuttable, and the city attorney may advise the commission that a presumption should not be followed in a specific case based on extrinsic evidence presented.
         (F)   Conflicting instruments. In the event that multiple protests and withdrawals are filed on behalf of the same owner, the instrument with the latest date and time of execution controls.
   (c)   Administrative plat process.
      (1)   Delegation of authority to subdivision administrator. The subdivision administrator may approve the following administrative plats as authorized by Texas Local Government Code Section 212.0065(a)(1) and (2) and this article:
         (A)   An amending plat (minor) that is filed only for one or more of the following:

            (iii)   To correct an error in a real property description shown on the preceding plat.
            (iv)   To indicate monuments set after the death, disability, or retirement from practice of the engineer or surveyor responsible for setting monuments.
            (v)   To show the location or character of a monument that has been changed in location or character or that is shown incorrectly as to location or character on the preceding plat.
            (vi)   To correct any other type of scrivener or clerical error or omission previously approved by the municipal authority responsible for approving plats, including lot numbers, acreage, street names, and identification of adjacent recorded plats.
            (vii)   To correct an error in courses and distances of lot lines between two adjacent lots if:
               (aa)    both lot owners join in the application for amending the plat;
               (bb)   neither lot is abolished;
               (cc)    the amendment does not attempt to remove recorded covenants or restrictions; and
               (dd)   the amendment does not have a material adverse effect on the property rights of the other owners in the plat. In this provision, material adverse effect means a significant and unwanted or negative result on the property rights of other owners in the plat.
         (B)   An amending plat (minor) that is not in a residential district and that is filed only for one or more of the following:
            (i)   To relocate a lot line to eliminate an inadvertent encroachment of a building or other improvement on a lot line or easement if the amendment does not increase or decrease the number of lots.
            (ii)   To relocate one or more lot lines between one or more adjacent lots if:
               (aa)   the owners of all those lots join in the application for amending the plat;
               (bb)   the amendment does not attempt to remove recorded covenants or restrictions; and
               (cc)   the amendment does not increase or decrease the number of lots.
            (iii)   To replat one or more lots fronting on an existing street if:
               (aa)   the owners of all the lots join in the application for amending the plat;
               (bb)   the amendment does not attempt to remove recorded covenants or restrictions;
               (cc)   the amendment does not increase or decrease the number of lots; and
               (dd)   the amendment does not create or require the creation of a new street or make necessary the extension of municipal facilities.
         (C)   A minor plat involving four or fewer lots fronting on an existing street, that is not in a residential district, and that does not require the creation of any new street or the extension of municipal facilities.
      (2)   A certificate of correction may be used to make the corrections listed in Subparagraph (1)(A), unless the subdivision administrator determines that a sketch is needed for clarity, in which case an amending plat must be submitted. A certificate of correction must be certified by a registered professional surveyor in a form approved by the chief city surveyor.
      (3)   Except as provided in this subsection, notice, a hearing, and the approval of other lot owners are not required for the approval and issuance of an administrative plat.
   (d)   Vacation plat.
      (1)   Any plat may be vacated upon application of the owners of the land in accordance with state law and this article.
      (2)   A vacation plat must be approved by the commission.
      (3)   An approved vacation plat must be recorded with the vacated plat and operates to destroy the effect of recording the vacated plat and to divest all public rights to the streets, alleys, and other public areas laid out or described in the vacated plat.
      (4)   Vacation of a park is prohibited unless approved as required by state law. (Ord. Nos. 20092; 21186; 22053; 22026; 23384; 24843; 25047; 26529; 26530; 27495; 28073; 28424 ; 31394; 32002)

SEC. 51A-8.404. ENGINEERING PLAN APPROVAL PROCEDURE.

   (a)   Generally. A person seeking approval of engineering plans for infrastructure must not submit those plans until a preliminary plat has been approved for the property which the infrastructure is to serve. After approval of the preliminary plat, plans for the infrastructure must be submitted to the department. The director shall review the plans submitted under this section for completeness.
   (b)   Contents of engineering plans. Plans submitted must include the following:
      (1)   All required fees.
      (2)   A completed private development checklist on a form provided by the department. The form must be signed by the professional engineer responsible for the plans.
      (3)   A completed fee receipt on a form approved by the director.
      (4)   Two blueline prints of the approved preliminary plat.
      (5)   Two sets of infrastructure plans.
      (6)   A copy of any specific use permit or planned development district ordinance regulating the property.
      (7)   A copy of any deed restrictions regulating the property in which the city of Dallas is an enforcing party.
   (c)   Staff review of engineering plans. All affected divisions of the department shall review the engineering plans against the established criteria and forward their comments to the director. Changes or corrections in the design or right-of-way requirements must be itemized and forwarded, in writing, to the responsible engineer and the owner as those persons are reflected on the private development checklist.
   (d)   Required off-site easements. If off-site easements or rights-of-way are required to accomplish the construction shown in the engineering plans, field notes describing the easements or rights-of-way, sketches showing the required easements or rights-of-way, copies of recorded deeds for all affected property, and agreements from the owners of the off-site property must be submitted before approval of the plans. The agreements are acceptable only if they are from the current owners and were executed less than one year before the time they are submitted.
   (e)   Director action. The director shall approve, approve with conditions, or disapprove engineering plans within 30 days after the date a complete application is filed under Subsection (b). The director shall not approve engineering plans that do not comply with the requirements of this article, the Dallas City Code, or state and federal law.
   (f)   Action letter. The director shall send an action letter to the applicant within 30 days after the date a complete application is filed under Subsection (b). If the director disapproved the engineering plans, the letter must contain the reasons for disapproval. If the director approved the engineering plans, the letter must contain all conditions of approval. The letter must contain a citation to the relevant section of the Dallas City Code or state or federal law for each reason for disapproval or condition of approval.
   (g)   Resubmission application.
      (1)   If the director approves an engineering plan with conditions or disapproves an engineering plan under Subsection (e), the applicant may file a resubmission application to address the conditions for approval or correct the reasons for disapproval. If the director determines that the application is complete, the director shall accept it and route it to all affected departments. If the director determines that the application is incomplete, the director shall return it to the applicant with a description of its deficiencies. If the director determines that the resubmitted engineering plan contains changes that are not required to address the conditions of approval or reasons for disapproval, or that the resubmitted application creates new conditions that do not comply with this article, the Dallas City Code, or state or federal law, the director shall reject the application and the applicant must submit a new engineering plan application. The director must approve, approve with conditions, or disapprove all resubmitted applications within 15 days after the date a complete resubmission application is accepted by the city. The director shall approve the application if he finds that it adequately addresses each condition for approval or reason for disapproval of the previous engineering plan application.
      (2)   The resubmission engineering plan application must contain all required fees and the following unless the director determines that an item listed is not applicable and may be omitted:
         (A)   A copy of the conditionally approved or previously disapproved engineering plan.
         (B)   A copy of the action letter sent by the director.

   (i)   Extension of infrastructure plan approval. An extension of the approval of the street paving, storm drainage, bridge, and culvert plans will be considered upon a formal request by the owner to the director of development services. Six-month extensions may be granted only if the conditions surrounding the plat, as well as the standards, criteria, and requirements listed in Section 51A-8.601 do not require a redesign of the infrastructure improvements. (Ord. Nos. 20092; 23384; 25047; 28073; 28424; 31394; 32002)

SEC. 51A-8.405. APPORTIONMENT OF EXACTIONS AND PARK LAND DEDICATION.

   (a)   See Section 51A-1.109 for regulations and procedures concerning apportionment of exactions.
   (b)   See Division 51A-4.1000 for regulations and procedures concerning park land dedication. (Ord. Nos. 26530; 30934)

SEC. 51A-8.501. COMPLIANCE WITH ZONING.

   (a)   Except as otherwise provided in Subsection (c), all plats must be drawn to conform to the zoning regulations currently applicable to the property. If a zoning change is contemplated for the property, the zoning change must be completed before the approval of any final plat of the property. A plat submission reflecting a condition not in accordance with the zoning requirements must not be approved by the commission until any available relief from the board of adjustment has been obtained.
   (b)   Except as otherwise provided in Subsection (c), no plat or replat may be approved which leaves a structure located on a remainder lot.
   (c)   Subsections (a) and (b) do not apply to a parcel, lot, or remainder lot that constitutes or is a part of a building site established pursuant to Section 51A-4.601(a)(5), (6), or (7) of this chapter. (Ord. Nos. 20092; 23384; 25809)

SEC. 51A-8.502. DESIGNATION OF ABANDONED, FRANCHISED, OR LICENSED PROPERTY.

   (a)   Indication of abandonment. Any abandoned public right-of-way that is to be incorporated into a platted lot must be indicated by a dashed line on the plat. The ordinance number for the ordinance abandoning the property must be reflected on the plat. Incorporation of property improperly abandoned is prohibited.
   (b)   Indication of franchise or license. Any franchise or license agreements affecting the property must be indicated on the plat.
   (c)   Estate in expectancy. Any property dedicated to the city as an estate in expectancy must be clearly indicated graphically, and labeled on the plat.
   (d)   Revocation of offer to dedicate through platting. Property previously offered for public dedication by the filing of a plat but not developed in any manner may be revoked through the filing of a replat of the property or a vacation plat if:
      (1)   the dedicated property was never used for the public purpose indicated on the plat dedicating the property or for utility or communication facilities; and
      (2)   no formal acceptance of the dedication was made by the city council or any city department. (Ord. Nos. 20092; 23384)

SEC. 51A-8.503. LOTS.

   (a)   Residential lot size. The size of each platted lot must comply with the minimum regulations for the zoning district in which the lot is located. Lots must conform in width, depth, and area to the pattern already established in adjacent areas, having due regard to the character of the area, its particular suitability for development, and taking into consideration the natural topography of the ground, drainage, wastewater facilities, and the proposed layout of streets.
   (b)   Frontage.
      (1)   All lots must front upon either a dedicated public street or a private street, unless this requirement is waived by an ordinance establishing a planned development district in which adequate access is provided by access easement. Platted lots may front upon a private street only if that street has been approved in accordance with the requirements of this chapter.
      (2)   For the purposes of this subsection:
         (A)    the frontage of a lot is the length of the lot’s intersection with a public or private street right-of-way line; and
         (B)   all of the property in a shared access development is considered to be one lot.
      (3)   Except in planned development districts, the minimum frontage requirement is 10 feet. The minimum frontage requirement for a planned development district is 10 feet unless otherwise provided in the ordinance establishing the district.
      (4)   If four or more single family, townhouse, and duplex lots share a private driveway, a private driveway easement must be provided. The private driveway easement must provide a minimum access width of 20 feet with a flare to 30 feet at its intersection with the curb line of a minor street, and a flare to 40 feet at its intersection with the curb line of a thoroughfare. The private driveway access easement need not be exclusive to a particular lot, but must be indicated on the plat, and must have direct access to a dedicated public street or a private street approved in accordance with this chapter. No more than four lots may share a private driveway access easement unless, upon recommendation from the director and the chief planning officer, the commission finds that the extraordinary topography or shape of the property unduly limits the development potential of the property, and that the proposed development is consistent with the spirit and intent of this chapter. The shared access area in a shared access development is not subject to this paragraph.
      (5)   Single family, duplex, or townhouse lots having frontage on two opposite sides are prohibited unless the commission finds that this design is essential to provide proper orientation of residential lots to thoroughfares. Shared access developments may have frontage on two opposite sides.
   (c)   Residential access to thoroughfares. Where single family, townhouse, or duplex lots abut a divided thoroughfare, driveway access to the thoroughfare is prohibited unless, upon recommendation of the director and the chief planning officer, the commission finds that the extraordinary topography or shape of the property unduly limits the development potential of the property, and the proposed development is consistent with the spirit and intent of this chapter. If the commission permits access under this subsection, the traffic barrier otherwise required in Section 51A-8.618 is waived.
   (d)   Municipal boundary lines. Plats divided by municipal boundary lines must be approved by the appropriate body of each affected municipality to be effective. Any building permit issued based on a plat divided by a municipal boundary line is void if the requisite approval has not been obtained.
   (e)   Lot lines and existing structures.
      (1)   No plat may be approved if an existing improvement on the property would encroach upon a proposed lot line or setback line, unless the existing improvement is to be removed or relocated, or unless the encroachment is authorized by the Dallas Building Code.
      (2)   No plat may be approved if the location of a proposed lot line would create a structure not in strict compliance with the Dallas Building Code, as amended, or the Dallas Development Code, as amended, unless the existing structure is to be removed, relocated, or altered to comply.
      (3)   Notwithstanding Paragraphs (1) and (2), dedications for public infrastructure may be accomplished even if a structure encroaches, provided appropriate language is executed to convey an estate in expectancy. (Ord. Nos. 20092; 21186; 23384; 24731; 25047; 28073; 29478 ; 31394)

SEC. 51A-8.504. BLOCKS.

   (a)   Block length. Block lengths in plats for single family lots should not exceed 1200 feet measured from block corner to block corner. The length may be extended if, upon recommendation from the director and the chief planning officer, the commission finds that the extraordinary topography or shape of the property unduly limits the development potential of the property, and that the proposed development is consistent with the spirit and intent of this chapter.
   (b)   Other considerations. Block length and width must be designed to accommodate the type of use anticipated and must provide for safe and convenient access and circulation. Block design must take into account the physical characteristics of the topography. (Ord. Nos. 20092; 23384; 25047; 28073; 29478)

SEC. 51A-8.505. BUILDING LINES.

   (a)   Building lines that establish a minimum front, side, or rear yard setback greater than the current zoning setback requirements, building lines for lots that border a natural creek channel, and building lines established by Section 51A-4.401(a)(3) must be shown on the plat.
   (b)   A building line may establish a minimum front, side, or rear yard setback greater than the minimum front yard setback required by zoning regulation only if the building line is part of a plan for the orderly development of a subdivision. Except as provided in Section 51A-8.510, a building line may not establish a minimum front, side, or rear yard setback less than the minimum front, side, or rear yard setback required by zoning regulation. The building line for lots that border a natural creek channel must provide the setback required by Section 51A-5.106. No other building lines may be shown on the plat.
   (c)   If an existing platted building line establishes a minimum front, side, or rear yard setback greater than the minimum front, side, or rear yard setback required by zoning regulation, relief from the platted building line must be sought through a replat submitted to the commission. The commission may approve a relocation or removal of the platted building line with a minimum front, side, or rear yard setback greater than required by zoning regulation only:
      (1)   upon the affirmative vote of at least three-fourths of the commission members present; and
      (2)   if the commission finds that relocation or removal of the platted building line will not:
         (i)   require a minimum front, side, or rear yard setback less than required by zoning regulation;
         (ii)   be contrary to the public interest;
         (iii)   adversely affect neighboring properties; and
         (iv)    adversely affect the plan for the orderly development of the subdivision.
   (d)   If relief is sought from the minimum front, side or rear yard setback required by zoning regulation, approval must be obtained from the board of adjustment.
   (e)   A building line platted and recorded prior to December 13, 2006, indicating that a front yard setback has been reduced remains enforceable. Removal of the platted building line may be sought through a replat that complies with this section.
   (f)   The subdivision administrator may not approve an administrative plat that adds, moves, or removes a building line. (Ord. Nos. 20092; 23384; 26529; 26531)

SEC. 51A-8.506. STREET LAYOUT.

   (a)   Generally. Streets must be designed in relation to the thoroughfare plan, existing and proposed streets, the terrain, streams, and other physical conditions. The arrangement of streets must provide for the continuation of streets between adjacent properties when the continuation is necessary for the safe and efficient movement of traffic, or for utility efficiency. Minor streets should be oriented in a manner that discourages their use by through traffic, and to allow efficient drainage systems, utility systems, and general street improvements. All streets must be designed and constructed in accordance with this section and Section 51A-8.604.
   (b)   Dead-end streets.
      (1)   Temporary dead-end streets. If adjacent property is undeveloped and a street must terminate temporarily, the right-of-way must extend to the boundary of the plat. When a temporary dead-end street is shown on a plat, a temporary circular or “T” shaped turnaround must be provided and shown as an easement on the subdivision plat, and must be indicated on the plat by dotted lines. No turnaround is required if the street is 150 feet or less in length, measured from the intersection of the street right-of-way lines with the subdivision boundary to the street’s intersection with a through street. All temporary turnarounds are subject to approval by the director.
      (2)   Permanent dead-end streets.
         (A)   Except as otherwise provided in this paragraph, if a permanent dead-end street is created within a proposed plat, a circular turnaround or other approved turnaround must be provided. The minimum radius for the circular turnaround is 50 feet for the right-of-way and 43.5 feet for the pavement measured to the back of the curb. The length of permanent dead-end streets must not exceed 600 feet, measured along the centerline from the block corner to the center of the cul-de-sac. The length of a permanent dead-end street may be extended upon recommendation of the director and the chief planning officer if they find that the extraordinary topography or shape of the property unduly limits the development potential of the property, and that the proposed development is consistent with the spirit and intent of this chapter.
         (B)   A waiver to the requirement of a turnaround for a dead-end street may be obtained from the director and the chief planning officer only upon their determination that a turnaround is not needed to serve the traffic on the street or otherwise needed to protect the public interest.
   (c)   Intersections. The following regulations govern the alignment of intersections:
      (1)   All streets must intersect as close to a right angle as permitted by topography or other natural physical conditions. A street must not intersect with another street or railroad at an angle of more than 105 degrees or less than 75 degrees.
      (2)   The intersection of two streets must not be located within 100 feet of a railroad right-of-way if one of the streets crosses the railroad right-of-way at grade. This 100 foot separation is measured from the nearest point of the intersection of the street right-of-way and the nearest point of the railroad right-of-way.
      (3)    A driveway or alley approach must not be located within 100 feet of a railroad right-of-way.
      (4)   An intersection must not have more than four street approaches.
      (5)   Proposed intersections along one side of an existing cross street must, wherever practical, align with existing intersections on the opposite side of the cross street. Street centerline offsets of less than 150 feet are not permitted unless the cross street is divided by a median without openings at either intersection.
      (6)   If served by a median opening, minor streets that intersect divided thoroughfares must be spaced at least 360 feet apart, measured from centerline to centerline unless otherwise approved by the traffic engineer.
   (d)   Private streets. If a private street is indicated in the street layout, it must be designed and constructed in accordance with this section and Section 51A-8.604.
   (e)   Street names. The naming of public or private streets created through the platting process is the responsibility of the applicant. Street names must conform to the standards for street names contained in Division 51A-9.300 of this chapter. All proposed street names must be reviewed by the fire department, the department of development services, and the police department before consideration by the commission. (Ord. Nos. 20092; 21186; 23384; 25047; 28073; 28424; 29478; 31314; 32002)

SEC. 51A-8.507. ALLEYS.

   (a)   When required. Alleys are required only in residential zoning districts, and then only when required under Section 51A-8.604 based on accommodation of street pavement width and zoning density. Alleys must provide continuous vehicular access regardless of zoning.
   (b)   Regulations. All alleys must meet the following standards:
      (1)   Alleys must have a minimum right-of-way of 15 feet in width.
      (2)   Alley right-of-way must not exceed 20 feet in width.
      (3)   Alleys must consist of at least 10 feet of pavement.
      (4)   Permanent dead-end alleys are not allowed unless all access is prohibited between the alley and public rights-of-way. Alleys must either intersect with a dedicated public or private undivided street or an existing alley. If a dead-end alley is shown on a proposed plat, an approved turnaround must be provided unless a waiver is obtained from the director and the chief planning officer. A waiver is permitted only if the director and the chief planning officer determine a turnaround is not necessitated by the amount of traffic on the alley, nor otherwise needed to protect the public interest.
      (5)   Alleys must function without reliance on fire lanes or access easements. An alley must provide vehicular access from a dedicated public right-of-way or easement to another dedicated public right-of-way along pavement which is all within dedicated public right-of-way.
      (6)   Alleys adjoining and parallel to divided thoroughfares must be separated from the thoroughfare by a traffic barrier in accordance with Section 51A-8.618 of this article.
      (7)   Dedications for an alley are required as provided in Section 51A-8.604(c). Where an alley intersects a street, a 15-foot visibility triangle (alley sight easement) is required. Measurements are taken along the property line.
      (8)   Alleys must be designed and constructed according to the requirements of the Street Design Manual and the Standard Details for Public Works Construction of the department of transportation and public works.
   (c)   Private alleys. If a private alley is indicated, it must be designed and constructed in accordance with all of the requirements in this section, and must be labeled as a private alley on the proposed plat. Easements for utilities and franchises must be dedicated in private alleys under the same circumstances and in the same manner as required for private streets pursuant to Section 51A-8.610 . (Ord. Nos. 20092; 23384; 25047; 28073; 28424; 29478; 30239 ; 30654; 31314 ; 32864 )

SEC. 51A-8.508. PARKS AND COMMON AREAS.

   (a)   Generally. If any portion of property subject to a plat application qualifies as a prospective park site pursuant to the standards and guidelines contained in the Long Range Physical Plan for Park and Recreational Facilities, the director of parks and recreation must be notified and given an opportunity to negotiate for the acquisition of the property by the city before a final plat is approved. If the applicant elects to make a commitment to sell that portion of the property to the city, he may designate the portion as a reservation for park use if the following requirements are met:
      (1)   The portion is of a suitable size, dimension, topography, and general character for its intended purpose.
      (2)   Adequate access to the portion is provided.
      (3)   The dimensions of the portion are clearly identified on the plat.
      (4)   Any development shown on the portion complies with the standards of the park and recreation department.
   (b)   Proper access. Land reserved for recreation sites and parks is considered to have proper access and visibility if:
      (1)   the property has frontage of at least 100 feet on an improved public street; or
      (2)   the property has a high degree of visibility and has paved public vehicular access to an improved public street. The paved access must be at least 20 feet in width and must comply with the construction standards of the department of transportation and public works.
   (c)   Utilities. Water, wastewater, and electrical facilities must be provided to the perimeter of the site.
   (d)   Common areas. Areas retained in private ownership but intended for the benefit of the owners of lots in the plat must be shown as common areas on the plat. A permanent maintenance plan must be approved for the area before release of the final plat. (Ord. Nos. 20092; 23384; 28424; 30239 ; 30654 ; 32864 )

SEC. 51A-8.509. FIRE AND POLICE ACCESS.

   (a)   Generally. The layout design of a plat must take into consideration the provision of adequate fire and police access.
   (b)   Water supply. Provisions must be made for the extension of water lines and the appropriate placement of fire hydrants as required by the department before approval of the final plat. (Ord. Nos. 20092; 23384; 25047; 28073)

SEC. 51A-8.510. COMMUNITY UNIT DEVELOPMENT.

   To encourage reasonable flexibility of design and arrangement in the development of residential communities in residential zoning districts, the following provisions are made for the approval of community unit developments (“CUD’s”):
   (a)   A CUD must be submitted for approval to the commission as a subdivision.
   (b)   A CUD must comply with the maximum lot coverage or density requirements for the district in which it is located. For purposes of calculating maximum lot coverage in a CUD, the calculation is made using either the actual size of the lot or the minimum lot area specified for the zoning district in which the lot is located, whichever is greater.
   (c)   The minimum lot area of any lot within the CUD may be reduced by an amount not to exceed 25 percent of the minimum lot area for the zoning district in which the CUD is located. Any reduction in minimum lot area must be compensated proportionally on a square foot for square foot basis by the establishment of permanent community open space to serve the property being platted. If five percent or more of the community open space is unimproved and in a flood plain (as defined in Article V), the minimum lot area may be reduced by up to 30 percent.
   (d)   Front yard, side yard, and rear yard requirements may be uniformly reduced on all lots and must establish a uniform pattern within the boundaries of the property being platted. The reduction in front yard, side yard, and rear yard must not exceed the total percentage reduction of lot area within the boundaries of the property being platted.
   (e)   The CUD must not be used to increase the number of lots which could normally be accommodated by the size of the site.
   (f)   The CUD provisions are not applicable to property located in a planned development district.
   (g)   Open space provided in a CUD must be approved as appropriate for its intended purpose by the director and the chief planning officer. The open space area must be within 1320 feet, measured radially, of any residential lot that is reduced in size in accordance with Subsection (c) of this section.
      (1)   Unimproved open space:
         (A)   may extend into floodway easements or floodway management areas;
         (B)   must be indicated on the plat with a prohibition of structures and parking areas; and

      (2)   Improved open space:
         (A)   must not extend into floodway easements or floodway management areas unless the proposed improvements are in compliance with Division 51A-5.100 of this chapter; and
         (B)   must be developed in accordance with a site plan approved by the city council after recommendation by the commission. The site plan must include the location and dimensions of all improvements and structures planned for the open space.
   (h)   A maintenance agreement for the open space area must be provided in a community unit development. The agreement must be approved as to form by the city attorney and executed by the owner(s) or homeowners’ association. (Ord. Nos. 20092; 22053; 22150; 23384; 25047; 28073; 29478)

SEC. 51A-8.511. CONSERVATION EASEMENT.

   (a)   The owner of the property to be platted may provide an easement on all or part of the property to conserve trees and other natural features, subject to acceptance by the city, to the city or jointly to the city and a nonprofit association dedicated to the conservation of land. Before the city may consider accepting the easement, or consider approving the acceptance of an easement with a nonprofit association as the joint grantee of a conservation easement, the owner shall provide the building official with a list of the protected trees by name (both common and scientific) and caliper or an estimate thereof calculated and documented in a manner approved by the city arborist, written consent by any lienholder of the property to subordination of the lienholder’s interest to the conservation easement area, and a preservation strategy for the easement. The grantee of a conservation easement, if not the city, should be an eligible grantee such that the grantor will have the option of receiving a property tax benefit on the assessed value of the conservation easement area. The conservation easement area should be accessible to the public for walking, upon trails if the area exceeds 30 acres, unless this activity poses a risk to endangered species.
   (b)   The easement must be approved by the building official and approved as to form by the city attorney.
   (c)   The owner may offer a conservation easement to the city through the city arborist, or to a nonprofit association approved by the city (a list of such associations may be obtained from the city arborist). (Ord. Nos. 22053; 23384; 24843)

SEC. 51A-8.512. SHARED ACCESS DEVELOPMENT.

(Ord. Nos. 20092; 21186; 23384; 25047; 28073; 28424; 30239; 30654; 31314; 32864; 33070)

SEC. 51A-8.602. DEDICATIONS.

   (a)   Generally. The owner of the property to be platted must provide an easement or fee simple dedication of all property needed for the construction of streets, thoroughfares, alleys, sidewalks, storm drainage facilities, floodways, water mains, wastewater mains and other utilities, and any other property necessary to serve the plat and to implement the requirements of this article. Dedications shown on plats are irrevocable offers to dedicate the property shown. Once the offer to dedicate is made, it may be accepted by an action by the city council, by acceptance of the improvements in the dedicated areas for the purposes intended, or by actual use by the city. No improvements may be accepted until they are constructed according to the approved plans, details, and specifications, and the final plat is filed for record in the office of the county clerk of the county in which the property is located.
   (b)   Apportionment of exactions. See Section 51A-1.109 for regulations and procedures concerning apportionment of exactions.
   (c)   Streets.
      (1)   The percentage of right-of-way dedication required for streets is as follows:
         (A)   When the full right-of-way width of a street is contained within the boundaries of a proposed plat, the entire required right-of-way contained within the boundaries of the plat must be dedicated.
         (B)   When a thoroughfare is along the perimeter of a proposed plat, sufficient right-of-way must be dedicated to provide one-half of the thoroughfare plan requirement, measured from the centerline of the existing right-of-way or, if there is no existing right-of-way, the proposed right-of-way as determined by the director and the chief planning officer. If the property on the side of the thoroughfare opposite the property to be platted is railroad right-of-way or a utility or floodway easement, or if some physical or topographical condition makes the property on that side of the street undesirable for street right-of-way, the commission may require a correspondingly greater dedication.
         (C)   When a thoroughfare has a city council approved detailed alignment, all right-of-way falling within the approved alignment and within the boundaries of the proposed plat must be dedicated.
         (D)   If substandard right-of-way exists for an existing perimeter thoroughfare based on the thoroughfare plan requirements, and the plat includes property on both sides of the existing thoroughfare, sufficient right-of-way must be dedicated to meet the entire right-of-way requirement.
         (E)   When substandard right-of-way exists based on this article for a perimeter minor street, sufficient right-of-way must be dedicated to meet one-half of the entire right-of-way width requirement.
         (F)   When no right-of-way exists and a minor street is proposed, whether perimeter or contained within the boundaries of the proposed plat, the full right-of-way width must be dedicated.
      (2)   The amount of right-of-way, pavement width, and minimum centerline radius for all minor streets must be provided in accordance with the chart in Section 51A-8.604.
      (3)   When property has been previously platted and improvements have been constructed, accepted, and used, the commission may waive the requirements for additional right-of-way for existing streets if:
         (A)   no realignment of any minor street is proposed;
         (B)   no change in zoning classification is proposed;
         (C)   the street has been improved with the required number of lanes, and the full right-of-way standard is not warranted by expected traffic volumes, property access requirements, truck, bus, and taxi loading, or pedestrian use;
         (D)   the director and the chief planning officer recommend the waiver; and
         (E)   the commission finds that the area is a redeveloping area.
   (d)   Corner clips and sight easements.
      (1)   Corner clips must be dedicated at all intersections by means of a street easement. A corner clip is a triangle with the legs along the edges of the street rights-of-way. The size of the corner clip is based on the city's current design standards. Corner clips must be sized to provide an adequate turning radius, or to maintain public appurtenances within the area of the corner clip.
      (2)   Sight easements must be provided if required by the Street Design Manual of the city of Dallas.
   (e)   Alley sight easements. Alley sight easements must be granted at the intersection of any alley with a street. The size of the sight easement is that of a triangle with legs along the property lines equaling 15 feet.
   (f)   Utilities and drainage easements. Easements necessary for poles, wires, conduits, wastewater, gas, water, telephone, electric power, storm drainage, and any other utilities needed to serve the property being platted must be granted. All easements must comply with the following standards:
      (1)   Unless the grantee of an easement gives express written approval, no structures, fences, trees, shrubs or any other improvement may be placed in, on, above, over, or across the easement. An exception to this rule is that paving for parking, walkways, and driveways may be constructed over or across utility or drainage easements unless such construction is specifically prohibited by the plat or easement instrument.
      (2)   Any structures, fences, trees, shrubs, or other improvements, including paving, exist at the pleasure of the grantee. The owner of the subservient estate is liable for the full cost for any adjustments, relocations, restorations, replacements, or reconstruction to any item placed within the easement other than the utilities. The grantee has no responsibility for any destruction or damage to items other than utilities placed within the easement. Grantees of easements have the right of ingress and egress to their respective easements for the purposes of constructing, inspecting, and maintaining their improvements.
      (3)   If alleys are not provided, rear lot drainage easements and facilities may be required to prevent cross-lot drainage.
   (g)   Floodways. Floodway management areas and floodway easements must be dedicated or granted in accordance with Section 51A-8.611. (Ord. Nos. 20092; 21186; 23384; 24843; 24859; 25047; 26530; 28073; 28424; 29478; 30239; 30654; 31314)

SEC. 51A-8.604. STREET ENGINEERING DESIGN AND CONSTRUCTION.

   (a)   Generally. Streets, whether dedicated to the public use or privately owned, must be designed in accordance with the Street Design Manual of the city of Dallas. The geometrics of streets must be designed to provide appropriate access for passenger, delivery, emergency, and maintenance vehicles.
   (b)   Street construction required.
      (1)   Within the boundaries of the proposed plat, the owner must construct all thoroughfares, minor streets, and alleys shown on the proposed plat.
      (2)   When a minor street is along the perimeter of the proposed plat and the street is not improved with an approved all weather paving material to a width of 20 feet, the owner must improve the street to that standard along the length of the proposed plat.
      (3)   When a thoroughfare is along the perimeter of the proposed plat for 1000 feet or more, the owner must construct thoroughfare, sidewalk, and storm drainage improvements to complete one-half of the thoroughfare requirements along the entire length of the plat, adjusted for any participation in the construction under Section 51A-8.614.
   (c)   Minor street criteria. If additional right-of-way for a minor street has been waived by the commission in accordance with Section 51A-8.602 (c)(3), the amount of street construction required for the streets on which the requirements have been waived is determined by the director of development services. Additional street construction may be required, if necessary, based on the existing condition or width of the streets, and if warranted by the expected traffic volumes, property access requirements, or truck, bus, and taxi loading. If additional right-of-way has not been waived, minor streets must be designed and constructed to meet criteria given in the Street Design Manual of the city of Dallas.
   (d)   Private streets criteria. When permitted, private streets are governed by the following regulations:
      (1)   Private streets must be constructed and maintained to the standards for public rights-of-way and must be approved by the director and the chief planning officer. Sidewalks are required and must be constructed and maintained to the standards for sidewalks in the public right-of-way. Water and wastewater mains must be installed in accordance with the applicable ordinances.
      (2)   A legal entity must be created that is responsible for street lighting, street maintenance and cleaning, and the installation and maintenance of interior traffic control devices. The legal instruments establishing the responsibility for a private street or alley must be submitted to the commission for approval, be approved as to legal form by the city attorney, and be recorded in the appropriate county. A provision must be included in the legal instruments that addresses the consequences of failure to maintain the private street or alley and its appurtenances, including the right, but not the obligation, of the city to take any action needed to bring the private street or alley into compliance.
      (3)   Private streets must contain private service easements including, but not limited to the following easements: utilities; storm drainage; fire lane; street lighting; government vehicle access; mail collection and delivery access; and utility meter reading access.
      (4)   Street lights comparable with those required on public rights-of-way must be provided. Street lighting design plans must be approved by the director based upon applicable guidelines.

         (ii)   diamond-shaped;
         (iii)   a minimum of 24 by 24 inches; and
         (iv)   installed pursuant to city traffic standards.
      (11)   Private streets and the area they serve must be platted.
      (12)   A guard house may be constructed at any entrance to a private street. All guard houses must be at least 30 feet from a public right-of-way.
      (13)   Any structure that restricts access to a private street must provide a passageway 20 feet wide and 14 feet high.
      (14)   One private street entrance must remain open at all times. If an additional private street entrance is closed at any time, it must be constructed to permit opening of the passageway in emergencies by boltcutters or breakaway panels.
      (15)   A private street system serving an area containing over 150 dwelling units must have a minimum of two access points to a public street.
      (16)   A private street system may serve no more than 300 dwelling units.
      (17)   The city has no obligation to maintain a private street. (Ord. Nos. 20092; 21186; 22392; 23384; 23535; 25047; 27495; 28073; 28424; 29478; 30239; 30654; 31314; 32002)

SEC. 51A-8.605. SANITATION COLLECTION ACCESS REQUIRED.

   (a)   Access required. The owner or homeowners’ association must provide access for city sanitation collection.

Adequate provision must be made for the acceptance, collection, conveyance, detention, and discharge of storm water runoff drainage onto, through, and originating within the subdivision. No final plat release may be issued until proper provision has been made for drainage.
      (2)   Private drainage systems are those which serve one lot or tract, or any open system that serves more than one lot or tract for which a private entity has maintenance obligations. Private systems are owned and maintained by a private entity. Easements must be provided to allow access by the city to any open system in the event that private system failure or diminished function jeopardizes the public's health, safety or welfare. Private storm water drainage systems must be designed in general conformance with the design standards of the department of water utilities as set forth in the Drainage Design Manual of the city of Dallas. Private enclosed systems are not required to be constructed according to the Standard Construction Details, File 251D-1.
      (3)   Public drainage systems are those systems which serve more than one lot or tract, excluding open systems maintained by a private entity. The portion of a drainage system located downstream from a lot or tract boundary, and the portion of any drainage system within the lot or tract boundary which conveys storm drainage from outside the lot or tract boundary are public systems. Public storm water drainage systems must be designed and constructed in strict conformance with department of water utilities requirements.
      (4)   The city owns and maintains public systems that have been constructed and accepted pursuant to Section 51A-8.612.
      (5)   All storm drainage facilities must be designed and constructed to safely drain a one-percent annual chance storm event as outlined in the Drainage Design Manual of the city of Dallas. Paved streets and alleys, ditches, and swales may be used for emergency overflow capacity in parallel with enclosed systems provided the requirements of the Drainage Design Manual of the city of Dallas are met.
      (6)   Storm water must be discharged in an acceptable form and at a controlled rate so as not to endanger human life or public or private property.
      (7)   The owner shall fund and construct all storm drainage outfalls necessary to safely and adequately drain the subdivision.

         (B)   A complete description of all control measures designed to control erosion and sedimentation of soils during and after construction. The owner is responsible for maintenance of erosion and sedimentation control measures during development and shall remove sediment from city right-of-way or storm drainage systems that occurs during the construction phase. Revegetation of the disturbed area is required as a part of the approved erosion control plan.
   (c)   Detention.
      (1)   Detention facilities required in this subsection must be designed to provide detention for the one-percent, two-percent, 10 percent, and 50 percent annual chance storm events. Detention must be provided in the following instances:
         (A)   The property to be platted is in or drains through the escarpment zone or a geologically similar area as defined in Division 51A-5.200 of this chapter.
         (B)   The development of the platted area results in an increase to the existing rate of runoff due to a rezoning of the platted area that allows higher density. Detention will not be required if:
            (i)   the rezoned area is in the redeveloped area and there is no increase in impermeable surface;
            (ii)   the change in zoning results in less than a 20 percent increase in the runoff, and the area rezoned is less than 3 acres, or an adequate outfall exists to handle the developed discharge; or
            (iii)   the rezoned area is less than one acre in size and adds less than 5,000 square feet of additional impervious surface relative to existing conditions.
         (C)   The proposed development does not have adequate outfall to carry the one-percent annual chance storm event without damaging property downstream, or the owner of downstream property refuses to provide the needed easements to the city. Detention will not be required under this subparagraph if the owner funds and constructs the storm drainage system to provide a one-percent annual chance storm event runoff carrying capacity.
         (D)   The property to be platted contributes to the storm drainage of a neighboring municipality having detention requirements, provided there are written agreements with the neighboring municipalities.
      (2)   Detention facilities must be designed and constructed in conformance with the Drainage Design Manual of the city of Dallas.
      (3)   Detention area easements must be dedicated on the plat when detention facilities are on-site, and dedicated by a separate instrument when detention facilities are off-site.
      (4)   Each adjoining property owner and his successors and assigns shall be responsible for simple, routine maintenance of the detention area easement. The city of Dallas is responsible for any major maintenance and repair work necessary for the public safety and welfare.
      (5)   The constructed detention facilities and pond area must remain to line and grade and must not be altered without the approval of the director of water utilities.
      (6)   If detention is provided due to inadequate outfall pursuant to Section 51A-8.611(c)(1), then upstream storm drainage systems must be designed for a one-percent annual chance storm event, up to the outfall into the detention basin. Drainage systems constructed downstream must be designed for a one-percent annual chance storm event of the drainage basin without taking into consideration the reduction in flow provided by the detention facility upstream, unless a lesser criteria is approved by the director of water utilities when the proposed development does not increase the stormwater drainage from the property and the director determines that the drainage system is not necessary to preserve public health or safety.
      (7)   Storm water runoff from any plat into a contiguous city may be required to comply with the criteria of the contiguous city as directed by the director of development services provided there is a written agreement in effect at the time.
      (8)   When development of the property downstream results in the construction of facilities designed to accommodate the one-percent annual chance storm event, and the detention facilities upstream are no longer necessary, the detention facilities may be abandoned and the land reclaimed for other purposes.
   (d)   Floodways.
      (1)   Generally. Floodways must be provided in accordance with the recommendation of the director of water utilities and the requirements of the commission to accommodate the one-percent annual chance storm event drainage flows. Floodway dedications must be identified on the plat and monumented on the ground. Floodway conditions must be satisfied before submitting a final plat for a certificate of approval. Division 51A-5.100 applies to all floodways.
      (2)   Floodway easements.
         (A)   Floodway easements are drainage areas dedicated to the city as an easement to prevent obstructions of floodway capacity in a flood plain. Except as provided in Paragraph (3), a floodway easement is required for any portion of a property that is within a flood plain.
         (B)   A 15-foot wide floodway access easement from a publicly dedicated right-of-way may be required and may extend along a creek, parallel to the top of the bank to inspect or maintain a floodway easement.
         (C)   The owner of a lot that includes a floodway easement is liable for floodway easement maintenance in compliance with this subsection, taxes, and all other standard property owner liabilities.
         (D)   Unless approved by the directors of development services and water utilities in an instrument filed in the county deed records or by a city council approved tree mitigation plan, structures, fencing, trees, shrubs, or any other improvement or growth may not be placed in or across any floodway easement.
         (E)   Common areas, such as in a CUD, may be located within floodway easements. Before the release of a final plat, access to the common area must be shown on the plat and a permanent maintenance plan must be approved as to form by the city for a common area within a floodway easement. Owners of a common area within a floodway easement are jointly and severally liable for the floodway easement common area maintenance in compliance with this subsection, taxes, and all other standard property owner liabilities.
         (F)   For purposes of this subsection, "maintenance" means removing any object or condition that, as determined by the director of water utilities, impedes the free flow of water. Maintenance includes:
            (i)   keeping the floodway easement free from any structures;
            (ii)   removing debris;
            (iii)   desilting lakes, ponds, and detention areas; and
            (iv)   controlling the growth of vegetation.
         (G)   The city retains the right, but not the obligation, to enter onto the floodway easement to inspect or maintain the easement. If the floodway easement is not maintained in compliance with this subsection, the city has the right, but not the obligation, to put the floodway easement in compliance with this subsection. The owner of the floodway easement must pay the city for maintenance work performed within 180 days after the date of presentation of the bill. If a bill is not paid by the owners when due, the city shall file a lien statement that includes expenses assessed, the name of the owner, if known, and the legal description of the lot with the county clerk of the county where the lot is located.
      (3)   Floodway management areas.
         (A)   Floodway management areas are drainage areas dedicated to the city in fee simple to prevent obstructions of floodway capacity in a flood plain. All floodways not dedicated as a floodway management area must be dedicated as a floodway easement.
         (B)   If any portion of the subject property is (1) within a flood plain and (2) abuts a public park, green belt, open space, trail system, or the Trinity River that has been recommended for improvement in a flood plain management plan, the Trinity River corridor plan, the park and recreation long range development plan, the park and recreation master plan, the trail network plan, or any other master plan adopted by the park and recreation board or city council, the directors of water utilities, development services, and parks and recreation must be notified and given an opportunity to negotiate for the acquisition of the property for a floodway management area before a final plat is approved. The property owner is encouraged, but not required, to donate the floodway management areas to the city.
         (C)   If the applicant donates or commits to sell that portion of the property to the city, the applicant must designate that portion as a dedication or reservation on the plat. Upon acquisition of the property, the city maintains the floodway management area.
         (D)   The area for each floodway management area must be identified on the plat in square feet or in acres.
         (E)   No lot may extend into a floodway management area.
   (e)   Lot to lot drainage. Each lot must be drained to an abutting street or alley unless the director of development services determines that drainage to a street or alley is infeasible. If the director of development services determines that street or alley drainage is not feasible, drainage may be provided as follows:
      (1)   If no more than the rear 15 feet of a lot drains toward the rear lot line, a well-pronounced swale must be provided as approved by the director of development services.
      (2)   If more than the rear 15 feet of a lot drains toward the rear lot line, a paved invert in a common area or a drainage easement is required. In order to accommodate the one-percent annual chance storm event, an enclosed drainage system with inlets may be designed. Each portion of the system that drains one lot must be a private system. Each portion of the system that drains more than one lot must be a public system within an easement. (Ord. Nos. 20092; 23384; 25047; 27333; 27572; 27697; 30994; 31314; 32002)

SEC. 51A-8.612. PRIVATE DEVELOPMENT CONTRACTS.

   (a)   Generally. Once the infrastructure plans and apportionment determination have been approved, but before the final release of a plat or approval of a zoning district classification or boundary change requiring an exaction, private development contracts must be executed by the chief engineer for development services to build the proposed infrastructure facilities. Private development contracts for water and wastewater improvements, if needed, must comply with Chapter 49 of the Dallas City Code. Private development contracts for other infrastructure improvements must comply with this section. In addition, to ensure that the city will not incur claims or liabilities as a result of the developer's failure to make payment in accordance with the terms of a private development contract, the director may require the developer, as a precondition of approval or release of a final plat or approval of a zoning district classification or boundary change requiring an exaction, to provide sufficient surety guaranteeing satisfaction of claims against the development in the event such default occurs. The surety shall be in the amount of the private development contract. The surety shall also be in the form of a bond, escrow account, cash deposit or unconditional letter of credit drawn on a state or federally chartered lending institution.

If the nonstandard material is to be located in a street or alley, or is otherwise intended for vehicular travel, a covenant agreement is required which provides a plan of perpetual maintenance at no cost to the city. If the nonstandard material is for a driveway, a sidewalk, or for another surface outside of the area between street curbs, or is not intended for vehicular travel, a written agreement is required between the owner of the property to be platted and the city. The owner is responsible for securing all required sidewalk, driveway, or street cut permits.

SEC. 51A-8.618. TRAFFIC BARRIERS.

   (a)   When required. For all property being platted with identifiable single family, duplex, or townhouse components that front on both an arterial and a public or private street or alley, traffic barriers must be constructed that separate the property from the arterial. See Section 51A-8.507(b)(6) for alley requirements.
   (b)   Easement. The owner must dedicate an exclusive barrier easement along the lots or alleys perimeter to the thoroughfare depending on who will maintain the barrier. Barrier easements must have a minimum width of three feet. If a screening wall serves as a traffic barrier, maintenance of the wall is the responsibility of each individual owner abutting the easement or the homeowners’ association.
   (c)   Design. The design and construction of traffic barriers must be approved by the director. If concrete is used for traffic barriers, it must be reinforced and have a minimum compressive strength of 3000 pounds per square inch at 28 days test. The traffic barrier must be at least 24 inches in height. All traffic barriers must be maintained by the property owner or a homeowners association.
   (d)   Timing of construction. All traffic barriers required by this article must be constructed concurrently with the adjoining street or, if the thoroughfare is already constructed or is not to be constructed with the subdivision infrastructure, before the issuance of a certificate of occupancy or utility connection for any structure within the boundaries of the plat.

The city of Dallas is responsible for any major maintenance and repair work necessary for the traffic barrier if the city has accepted it for maintenance. Any other type of traffic barriers is the responsibility of the homeowners’ association or the owner. (Ord. Nos. 20092; 21186; 23384; 25047; 28073)
