[Amended 11-11-2002 by Ord. No. 226]
All uses in all districts shall comply with all the performance standards listed in Article IV.
§ 165-54 Environmental protection.
The developer shall determine the presence of environmental or natural features on the site and shall meet the following standards of environmental protection. Site alterations, regrading, filling or clearing of vegetation prior to submission of the plans for development shall be a violation of this chapter.
A.
Floodplains. All such lands are identified on the Zoning Map. See Article VIII, Floodplain District, for specific regulations.[1]
B.
Slopes. In areas of slopes, i.e., those above 8%, the following standards shall apply:
(1)
Eight percent to 15%: No more than 60% of such areas shall be developed and/or regraded or stripped of vegetation.
(2)
Fifteen percent to 25%: No more than 40% of such areas shall be developed and/or regraded or stripped of vegetation.
(3)
Twenty-five percent or more: No more than 20% of such areas shall be developed and/or regraded or stripped of vegetation.
C.
Areas of moderate to high landslide susceptibility produced by the influence of natural and/or man-related activity. Plans for development within these areas must be submitted by a professional engineer or landscape architect and approved by the governing body.
D.
Woodlands. No more than 50% of any woodland, exclusive of public streets and rights-of-way, may be cleared or developed. The remaining 50% shall be maintained as permanent open space.
E.
Ponds or watercourses. These areas shall be left as permanent open space. No development, filling, piping or diverting shall be permitted except for required roads. Any soil disturbance or removal of vegetation within 100 feet of such ponds or watercourses is prohibited except where primary access is required. In such instances, additional environmental studies may be required at the discretion of the Bell Acres Planning Commission or Bell Acres Borough Council. For purposes of this section, a watercourse shall be defined as any stream or stream bed that has a contributory watershed of at least 10 acres, while a pond is defined as containing at least 10,000 square feet of surface, measured at the high water mark.
[Amended 12-11-2006 by Ord. No. 247]
F.
Stormwater drainage and management. Stormwater drainage and management plans that show how all stormwater is to be retained on site and infiltrated shall be submitted for any proposed residential development of three family units or more and for all nonresidential development. An informal plan describing the stormwater runoff shall be submitted for one and two dwelling units; however, Council reserves the right to request more definitive information. The intent of stormwater management is to limit postdevelopment runoff to predevelopment levels and to alleviate or mitigate downstream damage due to storm flows. Detailed requirements for stormwater drainage and management are specified in Chapter 149, Subdivision and Land Development, § 149-33 and Appendix E. It should be noted that on-site storm water retention is the preferred option and that the developer must show why this is not feasible if such plans do not include such a solution.

Repeat the observations as many times as necessary to provide that observations be made at the beginning and at the end of the fifteen-minute period and that there shall be at least as many observations as there are decibels between the lowest low indication and the highest high indication.
(3)
Calculate the arithmetical average of the observed central tendency indications.
B.
It shall be unlawful for any person to operate any fixed machinery or equipment or similar mechanical device in any manner so as to create any noise which would cause the noise level measured at the property line of the property affected by the noise emission to be beyond permitted levels.
(1)
Noise limits shall not exceed the following:
[Amended 12-11-2006 by Ord. No. 247]
Zoning District | Time Period | Sound Level (dBa) |
|---|---|---|
R1, R2, R3, R4, RR-1 | Anytime | 55 |
M1 | 7:00 a.m. to 10:00 p.m. | 60 |
M1, M2 | 10:00 p.m. to 7:00 a.m. | 55 |
(2)
If the measurement location is on a boundary between two zoning districts, the lower sound level shall apply.
§ 165-62 Sewage discharges.
No discharge at any point into any private sewage disposal system or stream or into the ground of any materials in such a way or in such nature or temperature as can contaminate any water supply or otherwise cause the emission of dangerous or objectionable elements or the accumulation of solid wastes conducive to the breeding of rodents or insects is permitted.
§ 165-63 Activities affecting atmosphere at lot lines.
No activities producing heat, cold, dampness or movement of air are permitted which shall produce any material effect on the temperature, motion or humidity of the atmosphere at the lot line or beyond.
§ 165-64 Vibrations.
No use shall cause earth vibrations or concussions in excess of the standards outlined below, with the exception of that vibration produced as a result of construction activity. The standards below are as set forth in the Table of Frequency Amplitude Relations. Vibration shall be expressed as displacement in inches and shall be measured with a standard three-component measuring system, which is a device for recording the intensity of any vibration in three mutually perpendicular directions.
Table of Frequency Amplitude Relations | |
|---|---|
Frequency of Ground Motion (cycles per second) | Maximum Amplitude of Ground Motion in Inches, Not More Than |
Up to 10 | 0.0305 |
20 | 0.013 |
30 | 0.0102 |
40 | 0.0076 |
50 | 0.0061 |
60 | 0.0051 |
§ 165-65 Electrical disturbances.
No electrical disturbance adversely affecting the operation at any point of any equipment other than that of the creator of such disturbance shall be permitted.
§ 165-66 Radioactive emissions.
No activity shall emit dangerous radioactivity which exceeds the standards established by the United States Atomic Energy Commission Rules and Regulations, Title 10, Atomic Energy, Part 20, Standards for Protection Against Radiation.
