PART 1: GENERAL REGULATIONS

SEC. 51P-193.103.  PURPOSE.

 (a)  In general.  This ordinance provides standards specifically tailored to meet the needs of 
the Oak Lawn area of the city of Dallas, which is currently recognized as an area of cultural and 
architectural importance and significance to the citizens of the city. The general objectives of these 
standards are to promote and protect the health, safety, welfare, convenience, and enjoyment of the 
public, and, in part, to achieve the following: 
  (1) To achieve buildings more urban in form. 
  (2) To promote and protect an attractive street level pedestrian environment with 
continuous street frontage activities in retail areas. 
  (3) To encourage the placement of  off-street parking underground or within 
buildings similar in appearance to non-parking buildings. 
  (4) To promote development appropriate to the character of nearby neighborhood 
uses by imposing standards sensitive to scale and adjacency issues. 
  (5) To use existing zoned development densities as a base from which to plan, while 
providing bonuses to encourage residential development in commercial areas. 
  (6) To discourage variances or zoning  changes which would erode the quantity or 
quality of single-family neighborhoods, or would fail  to adhere to the standards for multiple-family 
neighborhoods and commercial areas, or would fail  to comply with the overall objectives of the Oak 
Lawn Plan accepted and endorsed by the city council on December 14, 1983, by Resolution No. 83-4034. 
  (7) To promote landscape/streetscape quality and appearance. 
  (8) To aid the environment's ecological balance by contributing to the processes of 
air purification, oxygen regeneration, groundwater recharge, and storm water runoff retardation, while at 
the same time aiding in noise, glare, and heat abatement. 
  (9) To provide visual buffering and enhance the beautification of the city. 
  (10) To safeguard and enhance property values and to protect public and private 
investment. 
  (11) To conserve energy.

SEC. 51P-193.126. LANDSCAPE, STREETSCAPE, SCREENING, AND FENCING STANDARDS.


(a) Application of section.


(1) Except as provided, this section does not apply to single-family and duplex uses in detached structures. This section applies to residential development tracts. This section applies to attached or detached single-family uses in MF-1, MF-2, and MF-3 subdistricts. This section shall become applicable to all other uses on an individual lot when work on the lot is performed that increases the existing building height, floor area ratio, or nonpermeable coverage of the lot, unless the work is to restore a building that has been damaged or destroyed by fire, explosion, flood, tornado, riot, act of the public enemy, or accident of any kind.

(2) Once this section becomes applicable to a lot, its requirements are binding on all current and subsequent owners of the lot.

(3) If a specific site plan containing landscaping requirements was approved by the city plan commission or city council prior to February 9, 1985, and if the site plan is made part of an ordinance or a deed restriction running with the land to which the city is a party, the landscaping requirements of this section do not apply to the property that is the subject of the approved site plan as long as the site plan remains in effect.

(4) The board may grant a special exception to the landscaping requirements of this section if, in the opinion of the board, the special exception will not compromise the spirit and intent of this section. When feasible, the board shall require that the applicant submit and that the property comply with a landscape plan as a condition to granting a special exception under this subsection.


(b) Landscaping requirements in general.


(1) Designated landscape areas.


(A) In general.
(i) Each property owner is required to designate portions of the lot and parkway in the front, side, or rear yard for landscaping purposes. These designations must be shown on the landscape plan required by this section. The first required designation is that of the “landscape site area.” The exact size requirements for the landscape site area vary depending on the zoning classification of the property. The landscape site area may consist of one large contiguous area or several smaller non-contiguous areas.
(ii) The second required designation is that of the “general planting area.” The general planting area is a subarea of the landscape site area. Like the landscape site area, it may consist of one large contiguous area or several smaller non-contiguous areas.
(iii) The third required designation is that of the “special planting area.” The special planting area is a subarea of the general planting area. Again, the special planting area may consist of one contiguous area or several non-contiguous areas.
(iv) The fourth required designation is that of the “parkway planting area,” which, like the other areas, may consist of one contiguous area or several non-contiguous areas.
(v) The requirements for the landscape site area, general planting area, special planting area, and parkway planting area are different and vary depending on the zoning classification of the property. Among those things regulated are the amount and type of pavement allowed, the soil depth, and the type and density of plant materials. Specific requirements applicable to these designated areas are outlined in the subsections that follow.

(B) Pavement restrictions. No pavement other than pavement for pedestrians and non-motorized vehicles is permitted in the designated landscape site area, except that permeable pavement for motor vehicles is allowed in multiple-family subdistricts only. No pavement of any kind is allowed in the designated general planting, special planting, and parkway planting areas.

(C) Soil depth requirements. There are no minimum soil depth requirements for portions of the landscape site area that are outside of the general planting area. The minimum soil depth requirement for the parkway planting area and portions of the general planting area that are outside of the special planting area is 18 inches. The minimum soil depth requirement for the special planting area is 24 inches.

(D) Minimum planting requirements. The minimum planting requirements for designated landscape areas are as follows:
(i) Landscape site area. There are no minimum planting requirements for portions of the landscape site area that are outside of the general planting area.
(ii) General planting area. The general planting area must contain living trees, shrubs, vines, flowers, or ground cover vegetation. All plants in this area must be recommended for local area use by the director of park and recreation.
(iii) Special planting area. The special planting area must contain living trees, shrubs, or vines that are recommended for local area use by the director of park and recreation. Turf grass and ground cover are not counted toward meeting these minimum planting requirements. Initial plantings must be calculated to cover a minimum of 75 percent of this area at a minimum height of 24 inches within a three-year period. There must be at least one plant for each four square feet of this area unless a landscape architect recommends an alternative planting density as part of a landscape plan that the building official determines is capable of satisfying the minimum coverage requirement for this area.
(iv) Parkway planting area. The parkway planting area must contain living trees, turf grass, flowers, or ground cover vegetation that are recommended for local area use by the director of park and recreation. Initial plantings must be calculated to cover a minimum of 75 percent of this area within a three year period.

(2)  Irrigation and drainage systems.  

All landscaping required under this section must be irrigated and drained by automatic irrigation and permanent drainage systems installed to comply with industry standards. 

(3) Off-street parking and screening requirements.

(A) Surface parking screening. All surface parking must be screened from the street and residentially zoned property by using one or more of the following three methods to separately or collectively attain a minimum height of three and one-half feet above the parking surface:
(i) Earthen berm planted with turf grass or ground cover recommended for local area use by the director of park and recreation. The berm may not have a slope that exceeds one foot of height for each three feet of width.
(ii) Solid wood or masonry fence or wall.
(iii) Hedge-like evergreen plant materials recommended for local area use by the director of park and recreation. The plant materials must be located in a bed that is at least three feet wide with a minimum soil depth of 24 inches. Initial plantings must be capable of obtaining a solid appearance within three years. Plant materials must be placed 24 inches on center over the entire length of the bed unless a landscape architect recommends an alternative planting density that the building official determines is capable of providing a solid appearance within three years. This subsection supplements Section 51P-193.113(f).

(B) Surface parking screening with single-family or duplex adjacency. The three methods of providing screening listed above in Subsection (b)(3)(A) of this section may be used to provide screening to separate a surface parking area from an adjacent single-family or duplex subdistrict if the screening barrier is at least six feet in height. This subsection supplements Section 51P-193.113(f)(3).

(C) Off-street loading and garbage storage area screening.
(i) Off-street loading spaces and garbage storage areas in all subdistricts except single-family, duplex, and townhouse subdistricts must be screened from:
(aa) a public street that is adjacent to the lot; and
(bb) property in a residential district that is adjacent to or directly across an alley from the lot. This subparagraph modifies Section 51-4.602(b)(6).
(ii) Screening required by this subparagraph must be at least six feet in height measured from the horizontal plane passing through the nearest point of the off-street loading space or garbage storage area.
(iii) Required screening must be constructed of:
(aa) for off-street loading spaces, any of the materials described in Paragraph (3)(A) to separately or collectively attain the minimum height of six feet; and
(bb) for garbage storage areas, a solid wood or masonry fence or wall.
(iv) Access through required screening may be provided only by a solid gate that equals the height of the screening. The gate must remain closed at all times except when in actual use.
(v) No loading spaces or garbage storage areas may be erected or established in this district in violation of this subparagraph. All existing loading spaces and garbage storage areas in this district must be in full compliance with this subparagraph by September 13, 1994. No person shall have a nonconforming right to maintain a loading space or garbage storage area that does not fully comply with this subparagraph after September 13, 1994. (See Exhibit 193D-11.)

(D) Garage screening and landscaping. Aboveground parking structures must have a 10-foot landscaping buffer on any side facing a public right-of-way, residential district, residential subdistrict, or residential use. This landscape buffer must contain one tree for every 25 feet of frontage and evergreen shrubs planted three feet on center. Initial plantings must be capable of obtaining a solid appearance within three years.

(4) Sidewalks.

(A) In general. Each property owner is required to construct and maintain a sidewalk in an area parallel to and a certain distance from the projected street curb. The exact location and width requirements for the sidewalk vary depending on the zoning classification of the property. [See Subsection (B) below.] If the sidewalk is to be located in the front yard, the property owner must dedicate a sidewalk easement to the City to assure its availability to the public as a permanent pedestrianway. Except as otherwise provided in this article, the standards, provisions, and requirements of Chapter 43, “Streets and Sidewalks,” of the Dallas City Code, as amended, apply to all sidewalks and driveways in the SPD.

(B) Location. Required sidewalks must be constructed and maintained in the following described areas, except that a required sidewalk may be located farther from the projected street curb where necessary to avoid or preserve existing trees or structures, or to allow compliance with other landscaping requirements in this section:
(i) In residential subdistricts, in that area parallel to and between 5 and 10 feet from the back of the projected street curb.
(ii) In nonresidential subdistricts, in that area parallel to and between 5 and 12 feet from the back of the projected street curb.

(C) Minimum width. Required sidewalks must have the following minimum widths that are unobstructed by structures or plantings:
(i) In residential subdistricts, a minimum width of four feet.
(ii) In nonresidential subdistricts, a minimum width of six feet.

(5) Trees.

(A) Tree planting zone. For purposes of this section, the “tree planting zone” is that area parallel to and between two and one-half and five feet from the back of the projected street curb. [If the tree planting zone is in the parkway, the property owner must apply for a landscape permit before any required trees may be planted in the parkway. See Subsection (d) of this section for more details regarding parkway landscaping.]

(B) Number, location, and type of trees required. Each lot must have one or more trees whose trunks are located wholly within the tree planting zone. The number of required trees is determined by dividing the number of feet of lot frontage by 25. Fractions are rounded to the nearest whole number, with .5 being rounded up to the next higher whole number. All required trees must be recommended for local area use by the director of park and recreation. If a property owner cannot obtain a landscape permit to locate a required tree in the parkway, the owner shall locate the tree in the required front yard as near as practicable to the front lot line. If a lot has no front yard requirement and the property owner cannot obtain a landscape permit to locate a required tree in the parkway, the owner need not provide that required tree.

(C) Minimum tree height and trunk caliper. Required trees must have a minimum height of 14 feet, and a minimum trunk caliper of three and one-half inches measured at a point 12 inches above the root ball.

(D) Tree spacing requirements. Required trees must be spaced as uniformly as practicable. The trunk of a required tree must be within the following distance of another required tree:
(i) In residential subdistricts, 40 feet.
(ii) In nonresidential subdistricts, 60 feet.

(E) Minimum clearance above pavement. The property owner shall maintain all trees to comply with the following minimum vertical height clearances over street and sidewalk pavements:
(i) Thirteen and one-half feet above street pavement.
(ii) Eight feet above a public sidewalk or the sidewalk required under Subsection (b)(4) of this section.

(F) Tree grates required near sidewalks. Tree grates conforming to state standards and specifications adopted to eliminate, insofar as possible, architectural barriers encountered by aged, handicapped, or disabled persons, and of a size adequate to permit healthy tree growth must be provided for all trees whose trunks are within 18 inches of the sidewalk required under Subsection (b)(4) of this section.

TREE MITIGATION IN RESIDENTIAL DISTRICTS.


(G) Tree preservation and mitigation for residential development tracts. The tree preservation requirements of Division 51A-10.130, “Tree Preservation,” of Article X, “Landscape and Tree Preservation Regulations,” of Chapter 51A apply to residential development tracts with the following modifications:

(i) Alternate methods of compliance. If a property owner cannot plant a replacement tree on the residential development tract from which the protected tree was removed, the property owner shall comply with one of the following two requirements:
(aa) Plant the tree on other property within the Oak Lawn SPD, including public parks, with the written permission of the building official and the property owner of the lot where the tree is to be located.
(bb) Make a payment into the Oak Lawn Open Space Fund.

(ii) Additional payment for removal of majestic trees. For purposes of this paragraph, a “majestic tree” is defined as a protected tree with a caliper of 15 inches or more. If a majestic tree is removed from a residential development tract, in addition to mitigation or an alternate method of compliance, a payment must be made into the Oak Lawn Open Space Fund.

(H) Tree preservation and mitigation for single-family uses in residential subdistricts. The tree preservation requirements of Division 51A-10.130, “Tree Preservation,” of Article X, “Landscape and Tree Preservation Regulations,” of Chapter 51A apply to single-family uses in residential subdistricts with the following modifications:

(i) Alternate methods of compliance. If a property owner cannot plant a replacement tree on the lot from which the protected tree was removed, the property owner shall comply with one of the following two requirements:
(aa) Plant the tree on other property within the Oak Lawn SPD, including public parks, with the written permission of the building official and the property owner of the lot where the tree is to be located.
(bb) Make a payment into the Oak Lawn Open Space Fund.

(ii) Additional payment for removal of majestic trees. For purposes of this paragraph, a “majestic tree” is defined as a protected tree with a caliper of 15 inches or more. If a majestic tree is removed from a lot, in addition to mitigation or an alternate method of compliance, a payment must be made into the Oak Lawn Open Space Fund.

(I) Oak Lawn Open Space Fund. The department of development services shall administer a city account to be known as the Oak Lawn Open Space Fund. Funds from the Oak Lawn Open Space Fund must be used only for acquiring park and open-space property within the Oak Lawn SPD. The amount of the payment required is calculated by using the formula for appraising the value of a tree, as derived from the most recent edition of the Guide for Establishing Values of Trees and Other Plants published by the Council of Tree & Landscape Appraisers, unless another publication is designated by the building official. Payments made into the Oak Lawn Open Space Fund must be spent within 10 years of the date of payment.


(6) Landscape permit required

Unless an exemption in Subsection (a) of this section applies, an application for a landscape permit must be submitted to and approved by the building official before performing any work that will increase the existing building height, floor area ratio, or nonpermeable coverage of the lot. To obtain a landscape permit, a landscape plan must be submitted. Landscape plans required under this section must contain the following information:
(A) The date, scale, north point, and the names and addresses of both the property owner and the person preparing the plan.
(B) The location of existing boundary lines and dimensions of the lot, and the zoning classification of the property.

(H) The location of all existing and proposed loading and garbage storage areas.

(7) Reserved.

(8) When landscaping must be completed

If a landscape plan is required under this section, all landscaping must be completed in accordance with the approved landscape plan before the final inspection of any structure on the lot or, if no final inspection is required, within 120 days of the date of issuance of the landscape permit.

(9) General maintenance.

(A) All required landscaping must be maintained in a healthy, growing condition at all times. The property owner is responsible for the regular weeding, mowing of grass, irrigating, fertilizing, pruning, or other maintenance of all plantings as needed. Any plant that dies must be replaced with another living plant that complies with the approved landscape plan within six months after notification by the City. A required tree that dies after its original planting must be replaced by another living tree having a minimum height of 14 feet and a minimum trunk caliper of four inches measured at a point 12 inches above the root ball.

(B) Any damage to utility lines resulting from the negligence of the property owner, his agents, or employees in the installation and maintenance of required landscaping in the public right-of-way is the responsibility of the property owner. If a public utility disturbs a landscaped area in the public right-of-way, it shall make every reasonable effort to preserve the landscaping materials and return them to their prior locations after the utility work. If nonetheless some plant materials die, it is the obligation of the property owner to replace the plant materials.

(10) Reserved.

(11) Garbage storage area landscaping

Where a garbage storage area is in the required front yard, a landscape planting area must be established and maintained between the required screening wall for the garbage storage area and the front lot line. The landscape planting must be at least three feet wide and have a minimum soil depth of 24 inches. No pavement of any kind is allowed in this area. This area must contain living evergreen shrubs or vines that are recommended for local area use by the director of park and recreation. Initial plantings must be calculated to cover a minimum of 30 percent of the total wall area facing the street within a three-year period. Shrubs or vines must be planted 24 inches on center over the entire length of this area unless a landscape architect recommends an alternative planting density as part of a landscape plan that the building official determines is capable of satisfying the 30 percent minimum coverage requirement. All landscaping required by this paragraph must be in place by September 13, 1994. (See Exhibit 193D-12.)


(c) Private license granted. The city council hereby grants a private license to the owners of all property in the Oak Lawn SPD for the exclusive purpose of authorizing compliance with the parkway landscaping requirements of this section. A property owner is not required to pay an initial or annual fee for this license, although a fee may be charged for issuance of a landscape permit in accordance with the Dallas Building Code. This private license shall not terminate at the end of any specific time period, however, the city council retains the right to terminate this license whenever in its judgment the purpose or use of this license is inconsistent with the public use of the right-of-way or whenever the purpose or use of this license is likely to become a nuisance.

(d) Parkway landscaping.
(1) Reserved.

(2) Upon receipt of an application to locate trees, landscaping, or pavement [other than for the sidewalk required under Subsection (b)(4) of this section] in the parkway and any required fees, the building official shall circulate it to all affected city departments and utilities for review and comment. If, after receiving comments from affected city departments and utilities, the building official determines that the construction and planting proposed will not be inconsistent with and will not unreasonably impair the public use of the right-of-way, the building official shall issue a landscape permit to the property owner; otherwise, the building official shall deny the permit.

(3) A property owner is not required to comply with any parkway landscaping requirement of this section if compliance is made impossible due to the building official’s denial of a landscape permit.

(4) A landscape permit issued by the building official is subject to immediate revocation upon written notice if at any time the building official determines that the use of the parkway authorized by the permit is inconsistent with or unreasonably impairs the public use of the right-of-way. The property owner is not required to comply with any parkway landscaping requirement of this section if compliance is made impossible due to the building official’s revocation of a landscape permit.

(5) The issuance of a landscape permit under this section does not excuse the property owner, his agents, or employees from liability in the installation or maintenance of trees, landscaping, or pavement in the public right-of-way.

(e) Visual obstruction regulations. A property owner is not required to comply with the landscaping requirements of this section to the extent that they conflict with the visual obstruction regulations in Section 51-4.602(c). In the event of a conflict between this section and the visual obstruction regulations, the visual obstruction regulations control.
