Coppell City Zoning Code

ARTICLE 32

- SPECIAL AND ADDITIONAL REGULATIONS

Sec, 12-32-1.- Lot area.

1.

The minimum residential lot area for the various districts shall be in accordance with the individual use schedule except that a lot having less area than herein required which was an official "lot of record" prior to the adoption of this Ordinance may be used for a one-family dwelling and no lot existing at the time of passage of this Ordinance shall be reduced in area below the minimum requirements set forth in the respective district.

2.

Public and semi-public institutions such as hospitals, churches and schools located in any district shall have a minimum site area of two acres.

3.

Location of dwellings and buildings. Only one main building for one-family and two-family use with permitted accessory buildings may be located upon a lot or unplatted tract. Every means of access shall have a minimum width of 25 feet. Where a lot is used for retail and dwelling purposes, more than one main building may be located upon the lot, but only when such buildings conform to all the open space, parking and density requirements applicable to the uses and districts. Whenever two or more main buildings, or portions thereof, are placed upon a single lot or tract and such buildings do not face upon a public street, the same may be permitted when the site plan for such development is approved by the planning and zoning commission so as to comply with the normal requirements for platting. No parking area, storage area, or required open space for one building shall be computed as being the open space, yard, or area requirements for any other dwelling or other use.

(Ord. No. 91500)

Sec. 12-32-2. - Front yard.

1.

On corner lots, the front yard set back shall be observed along the frontage of both intersecting streets (unless shown specifically otherwise on a final plat according to section 12-32-3 (1).

2.

Where the frontage on one side of a street between two intersecting streets is divided by two or more zoning districts, the front yard shall comply with the requirements of the most restrictive district for the entire frontage. (See appendix illustration no. 6)

3.

The front yard shall be measured from the property line to the front face of the building, covered porch, covered terrace or attached accessory building. Eaves and roof extensions or a porch without posts or columns may project into the required front yard for a distance not to exceed four feet and subsurface structures, platforms or slabs may not project into the front yard to a height greater than 30 inches above the average grade of the yard. (See appendix illustration no. 7)

4.

Where lots have double frontage, running through from one street to another, a required front yard shall be provided on both streets unless a building line for accessory buildings has been established along one frontage on the plat or by ordinance, in which event only one required front yard need be observed. (See appendix illustration no. 8)

5.

The minimum front yard setback requirements may be reduced by five feet in all single family except the 2F-9 district provided that at least 50 percent of the structures on a given block are set back an additional five feet from the original setback. The average setback would equal the original setback requirement. The purpose of this requirement is to encourage a variety of front yard setbacks along a street creating a more pleasing appearance of houses in the subdivision. In no case shall the front yard setback be less than 20 feet. (See appendix illustration no. 10). Varying setbacks must be shown on the approved final plat in order to reduce normal setback requirements.

6.

Minimum front yard setbacks for lots with predominate frontage on the curved radius of a cul-de-sac shall be 25 feet if approved on the final plat. (See appendix illustration no. 14)

7.

No fence, wall, screen, billboard, sign, structure or foliage of hedges, trees, bushes or shrubs shall be erected, planted or maintained in such a position or place so as to obstruct or interfere with the following minimum sight line standards.

(A)

Vision at all intersections where streets intersect at or near right angles shall be clear at elevations between two and one-half feet and nine feet above the average street grade, within a triangular area formed by extending the two curb lines from their point of intersection (see figure 4 of the subdivision ordinance) 45 feet, and connecting these points with an imaginary line, thereby making a triangle. If there are no curbs existing, the triangular area shall be formed by extending the property lines from their point of intersection 25 feet and connecting theses points with an imaginary line, thereby making a triangle.

8.

Gasoline service station pump islands may not be located nearer than 18 feet to the front property line. An enclosed canopy for a gasoline filling station may extend beyond the front building line but shall never be closer than ten feet to the property line.

9.

Where a future right-of-way line has been established for future widening or opening of a street or thoroughfare, upon which a lot abuts, then the front or side yard shall be measured from the future right-of-way line.

(Ord. No. 91500)

Sec. 12-32-3. - Side yards.

1.

On a corner lot used for one-family dwellings, both street exposures shall be treated as front yards on all lots platted after the effective date of this Ordinance, except that where one street exposure is designated as a side yard by a building line shown on a plat approved by the planning and zoning commission containing a side yard of 15 feet or more the building line provisions on the plat shall be observed. On lots which were official lots of record prior to the effective date of this Ordinance, the minimum side yard adjacent to a side street shall comply with the minimum required side yard for the respective districts.

2.

Every part of a required side yard shall be open and unobstructed except for accessory buildings as permitted herein and the ordinary projections of window sills, belt courses, cornices, and other architectural features not to exceed 12 inches into the required side yard, and roof eaves projecting not to exceed 36 inches into the required side yard.

(Ord. No. 91500)

Sec. 12-32-4. - Lot coverage.

Water stand pipes and tanks, church steeples, domes, and spires and school buildings and institutional buildings may be erected to exceed three stories in height, provided that one additional foot shall be added to the width and depth of front, side, and rear yards for each foot that such structures exceed three stories.

2.

Antennas and other sending and receiving devices of micro-wave or electromagnetic waves shall be permitted in all districts for private or amateur radio broadcasting use. Such devices shall not interfere with radio or television reception of adjoining property owners and shall comply with all regulations of the Federal Communications Commission (FCC). In no case shall the height of such antennas exceed 35 feet and proper guy wire securement shall be followed. In no manner shall the use of such equipment infringe upon adjoining property owners.
