(These principles include but are not limited to runoff calculations, retention of stormwater standards, slope limitations, preservation of natural features and topography, standards for stripping of vegetation, retention of natural vegetation and stockpiling of soil, minimization of disturbed area and duration of exposure, permanent vegetative and structural erosion control, retention and removal of stormwater sediment in runoff water, procedures for protecting soils or geologic formations, and such other requirements or exceptions as are consistent with the terms of principles as may be imposed by Township Engineer) Special requirements for agricultural and/or logging and woodcutting operations to prevent accelerated erosion and resulting sedimentation, earth disturbance activities relating to agricultural and/or logging and woodcutting operations must be conducted with consideration to the principles outlined in subparagraphs 1-6. These principals include but are not limited to the following: Minimum standards and principles for agricultural operations such as minimum distances to streams, permanent cover protection within right-of-way of township roads, slope limitations, and diversion terraces. This section includes principles for logging or woodcutting operations, which include but are not limited to retention of stumps, groundcover and root mat requirements, methods for removal of logs and removal routes, slopes limitations, maximum slope prohibitions, and design criteria.
All earth disturbances greater than 1000 square feet must be done under an erosion and sedimentation control permit issued by New London Township. All earth disturbances greater than 1 acre must be done under a stormwater NPDES permit and have a post-construction stormwater management plan.
4. Exemptions: This section includes various exemptions from the requirements of on-site stormwater runoff control. This provision includes emergency, maintenance, gardening and improvement-related exemptions as defined in subsections 4A-D.
5. Protection of Adjacent Property: These principles prohibit any person from engaging in earth moving sufficiently close to another public property from settling, cracking or other damage which might result from such earth movement.
No person shall dump, move, or place any soil, bedrock or other material or divert or increase the flow of water so as to cause the same to be deposited upon or roll, flow or wash upon or over the premises of another without express consent of owner of such premises, or upon or over any public street, street improvement, road, storm sewer drain, watercourse, or right of way or any public property.
No person shall when hauling soil, bedrock or other material over any public street, road, alley or public property, allow such material to blow or spill over and upon such street, road, alley or public property or adjacent private property.
This provision includes the procedure for the correction of any violation of this ordinance and the reimbursement to the Township for any costs incurred for any of these violations.
This provision prohibits the transfer of stormwater from one watershed to another unless the terms of this section are satisfied.
