Specific industrial uses are not excluded from this district, however, all proposed industrial uses shall be accompanied by a development site plan and where 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 and are determined the maximum allowable within single or combined industrial use or district.
C.
DEVELOPMENT SITE PLAN.
A development site plan shall be required for each building permit application and shall contain the following information:
1.
A scale drawing showing the boundary of the tract and topography with a contour interval of not less than two (2) foot intervals.
2.
Where buildings and/or other structures are proposed a site plan showing the location of each building and the minimum distance between buildings and between buildings and the property line, street line and/or alley line shall be submitted.
3.
A plan indicating the arrangement and provision of off-street parking, off-street loading, outside storage areas, method and location of storage area screening and points of entry from adjoining thoroughfare.
4.
A table showing net land area, ratio of building and outside storage areas to net land area.
5.
A table of performance standards if deemed by the Zoning Administrator necessary by the characteristics of industrial activities to be conducted on the site.
6.
Scale, north arrow, and names and addresses of owners and/or developers with name(s) and address(es) of those responsible for preparation of the development plan.
7.
For development projects influenced by or containing major drainageways or containing areas floodprone by definition of the City Engineer, preliminary drainage plan shall become part of the development site plan. This requirement may be waived only by the recommendation of the City Engineer.
8.
Any other information deemed appropriate.
The development site plan must be approved [by the] Planning and Zoning Commission prior to the issuance of a building permit. The Planning and Zoning Commission may impose reasonable buffers, screening, setbacks, or performance standards to protect the health, safety and welfare of the community and preserve and protect surrounding property and land uses. |
D.
HEIGHT AND AREA REGULATIONS.
No building shall exceed seventy-five feet (75') in height unless set back from all lot lines one foot (1') for each foot above the herein stated height limit. When building is located adjacent to residential or apartment use district, it shall not exceed forty feet (40') in height unless it is set back one foot (1') from all required yard limits for each one foot (1') from all required yard limits [sic] for each one foot (1') of additional height above forty feet (40').
Front Yard: There shall be a front yard of not less than thirty feet (30').
Side Yard: There shall be side yards of not less than fifteen feet (15') on corner lots on the side of lots facing on a street. For interior lots, a minimum ten foot (10') side yard shall be required except any additional emergency access as may be specified by the Fire Marshal.
Rear Yard: A minimum twenty foot (20') rear yard shall be required except any additional emergency access as may be specified 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 is to emit sanitary sewage effluent containing industrial wastes or other effluent into City of Blue Mound sanitary sewage system which is considered by the City of Engineer to be unusual to or be damageable to the sanitary sewage systems, a description of methods of pretreatment of the effluent must accompany the development 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.
Noise: The day-night average sound level at the property line shall not exceed seventy-five (75) decibels, unless the property line adjoins property zoned for residential uses where the maximum day-night average sound level shall not exceed sixty-five (65) decibels. The day-night average sound level (ldn) is the twenty-four (24) hour average sound level, in decibels, obtained after addition of ten sound decibels to sound levels in the night from 10:00 ten (10) decibels to sound levels in the night [sic] from 10:00 p.m. to 7:00 a.m.
Vibration: At the point of measurement taken on the property line of the source property which has the highest reading, 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, unless the point of measurement is located on a property line which is also the boundary line of a residential district in which case 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 Chapter, which are continuous or, if in discrete pulses, are more frequent than sixty (60) per minute. Impact vibrations, that is discrete pulses which do not exceed sixty (60) pulses per minute, shall not cause in excess of twice the displacement stipulated. |
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 twenty (20) percent averaged over a five (5) 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:
1.
One hundred micrograms per cubic meter of air sampled averaged over any five consecutive hours.
2.
Two hundred micrograms per cubic meter of air sampled, averaged over any three consecutive hours.
3.
Four hundred micrograms per cubic meter of air sampled, averaged over any one hour.
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 establish additional performance standards, including setbacks, berms, and buffers, for the sitting of facilities which handle, treat, store, or dispose of potentially hazardous or dangerous materials.
