River Oaks City Zoning Code
SECTION 17
"I" INDUSTRIAL DISTRICT.
A.
PURPOSE.
The purpose of this district is to regulate those uses that involve the manufacturing, assembly, processing, storage and/or distribution, sale and repair of materials, goods, parts, products, equipment, machinery, and other such operations incidental to industrial uses. It is not the intent of these regulations to allow the construction or development of residential uses within this district and those residential uses existing at the time of the adoption of this Zoning Ordinance may continue as nonconforming uses. Since the intended use may cause a detrimental change to the environment or substantially affect the municipally operated utility or thoroughfare systems, detailed descriptions of performance standards are included in these district regulations.
B.
USE REGULATIONS.
In the "I" Industrial District, no building or land shall be used and no buildings shall be erected, reconstructed, altered, or enlarged except for an industrial and/or commercial use in accordance with an approved site plan and performance standards imposed in the site plan and in this Ordinance.
C.
ACCESSORY USES.
In addition to those accessory uses specifically authorized in Section 22 of the Ordinance, any use may be established as an accessory use to a permitted use when it complies with the conditions for an accessory use as defined in this Ordinance.
D.
DEVELOPMENT REGULATIONS.
In the "I" Industrial District, the following development regulations shall be applicable to all uses:
1.
Height.
No structure shall exceed 75 feet in height unless the required yards are increased one foot for each one foot of additional height above 75 feet. When a building is located adjacent to any residential district, it shall not exceed 40 feet in height unless the required yards are increased one foot for each one foot of additional height above 40 feet.
2.
Front Yard.
Where the side of an "I" zoned lot abuts on property zoned for single-family uses there shall be a front yard of a size not less than the front yard required for the single-family residential property. Where the side of the "I" zoned lot does not abut property zoned as single-family residential, there shall be a front yard of not less than 25 feet, or the front yard indicated on a city-approved plat as filed in the Tarrant County Plat Records, whichever is greater. Corner lots shall have a minimum side yard of 15 feet on the second front yard, the yard generally parallel to the street with the greatest frontage, unless reversed frontage is approved by the zoning administrator. If a building line shown on a city-approved plat as filed in the Tarrant County Plat Records is greater than 15 feet, then the platted building line shall be required on the second front yard.
3.
Side Yard.
There shall be a side yard of not less than 10 feet, unless additional emergency access is required by the Fire Marshal.
4.
Rear Yard.
There shall be a rear yard of not less than 20 feet, unless additional emergency access is required by the Fire Marshal.
E.
PERFORMANCE STANDARDS.
The following are maximum accepted levels of noise, vibration, smoke, particulate matter and toxic and noxious matter allowable for industrial uses. If the proposed use results in the discharge of sanitary sewage effluent containing industrial wastes or other effluent into the city sanitary sewage system, a characterization of the effluent and a description of proposed methods of pretreatment (if any) must accompany the site plan.
The performance standards report may be waived by the zoning administrator if the proposed use is considered not to produce the listed effects.
1.
Noise.
The day-night average sound level at the property line shall not exceed 75 decibels, unless the property line adjoins property zoned for residential uses where the maximum day-night average sound level shall not exceed 65 decibels. The day-night average sound level (Ldn) is the 24 hour average sound level, in decibels, obtained after addition of 10 decibels to sound levels in the night from 10:00 p.m. to 7:00 a.m.
2.
Vibration.
The sound pressure level or impact level of any operation or plant shall not exceed the decibel limits for the octave bands designated in Column I below as measured at the point which has the highest reading on the property line of the source property. If the point of measurement is located on a property line which is also the boundary line of a residential district, the limits set forth in Column II shall apply.
Frequency (Cycles per Second) | Column I Displacement (Inches) | Column II* Displacement (Inches) |
|---|---|---|
0 to 10 | .0022 | .0008 |
11 to 20 | .0016 | .0005 |
21 to 30 | .0010 | .0002 |
31 and over | .0005 | .0001 |
*Steady State - Vibrations, for the purpose of this section, which are continuous or, if in discrete pulses, are more frequent than 60 per minute. Impact vibrations, which are discrete pulses which do not exceed 60 pulses per minute, shall not cause in excess of twice the displacement stipulated. |
3.
Smoke, Particulate Matter and Visible Emissions.
Smoke or visible emissions emitted from any vent, stack, chimney, skylight, or window shall not exceed an opacity of 20 percent averaged over a five minute period. Any emission of air pollutant must be in accordance with the requirements of the State of Texas. Emissions shall not exceed any of the following net ground level concentrations:
4.
Toxic and Noxious Matter.
The handling, processing, storage and disposal of hazardous, toxic, or noxious materials within this district shall be in accordance with applicable State and Federal laws and regulations. In addition, the planning and zoning commission may recommend and/or the city council may establish performance standards, including setbacks, berms, and buffers, for the citing of facilities which handle, treat, store, or dispose of potentially hazardous or dangerous materials.
5.
Additional Standards.
The planning and zoning commission may recommend and/or the city council may establish additional performance standards to protect neighboring areas and land uses from potential hazards and nuisances, including, but not limited to control over odor, glare and fire hazards.
F.
SITE PLAN.
1.
An approved site plan shall be a prerequisite for the granting of "I" Industrial District zoning and for the issuance of a building permit or certificate of occupancy for any property in an "I" Industrial District. The site plan shall contain the information required by Section 25 of this Ordinance.
2.
All improvements to the land and all buildings and construction on the land shall be in accordance with the site plan approved with the zoning request. The zoning administrator may authorize minor changes to the site plan in accordance with Section 25 of this Ordinance. If in the opinion of the zoning administrator, the proposed amendment to the site plan does not constitute a minor change, the proposed amendment shall be processed in accordance with the requirements for zoning changes as set forth in Section 29.
