In granting a permit under this chapter, the standards and considerations taken into account shall include but not be limited to the following:
Excavation, filling, grading, clearing and timber harvesting shall be permitted to be undertaken only in such locations and in such a manner as to minimize the potential of erosion and sediment and the threat to the health, safety and welfare of neighboring property owners and the general public.
Site preparation and construction shall be fitted to the vegetation, topography and other natural features of the site and shall preserve as many of these features as feasible.
The control of erosion and sediment shall be a continuous process undertaken as necessity prior to, during and after site preparation and construction.
The smallest practical area of land shall be exposed by site preparation at any given time.
The exposure of areas by site preparation shall be kept to the shortest practical period of time prior to the construction of structures or improvements or the restoration of the exposed areas to an attractive natural condition.
Following initial soil disturbance or redisturbance, permanent or temporary stabilization shall be completed within seven calendar days. The remaining disturbed area of the development shall be stabilized within 14 calendar days except for those areas in which actual construction activities are currently being performed.
Where slopes are to be revegetated in areas exposed by activity subject to permit, the slopes shall not be of such steepness that vegetation cannot be readily established or that problems of erosion or sediment may result.
Revegetation activities shall avoid the planting of trees with the characteristics of willows and Lombardi poplars within 75 feet of existing or proposed public water or sewer mains or drains.
Activity subject to permit shall not adversely affect the free flow of water by encroaching on, blocking or restricting watercourses.
Existing hills, trees and ground cover fronting along adjacent property and watercourses shall be preserved, maintained or supplemented by selective cutting, transplanting and the addition of new trees, shrubs and other ground cover for the purpose of providing a buffer when one is required by Chapter 158, Zoning, or elsewhere in the Town's Code.
The proposed activity shall not adversely affect soil fertility, drainage and lateral support of abutting land or other properties.
All fill material shall be of a composition suitable for the ultimate use of the filled land, free of rubbish and carefully restricted in its content of clearing debris, rocks, frozen material and soft or easily compressible material.
Fill material shall be compacted sufficiently to prevent problems of erosion.
All topsoil which is excavated from a site shall be stockpiled and used for the restoration of the site, and such stockpiles, where necessary, shall be seeded or otherwise treated to minimize the effects of erosion within the time period stipulated by the authorized official or Planning Board.
Prior to, during and after site preparation and construction, an integrated drainage system shall be provided which at all times minimizes erosion, sediment, hazards of slope instability and adverse effects on neighboring property owners.
The natural drainage system shall generally be preserved in preference to modifications of this system, excepting where such modifications are necessary to reduce levels of erosion and sediment and adverse effects on neighboring property owners.
All drainage systems shall be designed to handle adequately anticipated flows both within the site and from the entire upstream drainage basin.
Sufficient grades and drainage facilities shall be provided to prevent the ponding of water, unless such ponding is proposed within site plans, in which event there shall be sufficient water flow to maintain proposed water levels and to avoid stagnation.
There shall be provided where necessary to minimize erosion and sediment such measures as benches, berms, terraces, diversions and sediment debris and retention basins.
Drainage systems, plantings and other erosion or sediment control devices shall be maintained as frequently as necessary to provide adequate protection against erosion and sediment and to ensure that the free flow of water is not obstructed by the accumulation of silt, debris or other material or by structural damage.
All clearing debris, boulders and other debris resulting from site preparation activities or related operations shall be disposed of by methods accepted by the authorized official or Planning Board.
Timber harvesting for a commercial purpose and, when feasible, other site preparation activity shall be avoided within 50 feet of a stream, river, creek, gully or ravine, and all clearing or other debris shall be removed from watercourses.
Skidding logs up or down a watercourse is prohibited, and skidders shall be kept at least 50 feet from a watercourse, and logs that lie closer or on steep slopes shall be winched off to prevent soil disturbance.
All crossing of watercourses during site preparation activities shall be at points having low stable banks, a firm bottom and gentle slopes along the approaches.
The design and construction of sediment control practices and site preparation work, plus specifications and timing schedules, including extensions of previously approved plans, shall comply with provisions for erosion and sediment control in accordance with standards and specifications contained in a manual entitled "New York Guidelines for Urban Erosion and Sediment Control," published by the United States Department of Agriculture Soil Conservation Service, as it may be revised. Said manual shall be on file at the authorized official's office. In the event of conflict with this chapter, the provisions herein shall prevail.
Site preparation activities shall be conducted only between the hours of 7:30 a.m. and 6:00 p.m. when within 1,500 feet of any residence. No site preparation activity shall be conducted on Sundays or public holidays without express consent with the permit.
Any contract to perform site preparation activities shall state that it is subject to this chapter of the Code.
As a condition of its permit, the applicant shall be required to sign a permit authorizing Town officers, employees or agents to enter onto the site to perform appropriate surveillance.
The authorized official or Planning Board may impose any other reasonable conditions, including but not limited to screening, access controls, dust controls and site security, believed to be necessary.
After the approval of the application and before the issuance of any permit subject to the approval of the Planning Board, the applicant shall file with the Town Clerk, in an amount of the estimated cost of the project as submitted under § 75-8 of this chapter and verified by the appropriate official, one of the following performance guaranties, which must be approved by the Town Attorney as to form:
The Town Planning Board may grant a waiver of such guaranty if it deems the proposed activities to be of minor scope and to be consistent with the provisions of this chapter.
The party or parties filing the performance guaranty shall provide that either upon termination of the permit or the operation, whichever may come first, the project shall be in conformity with both the approved specific requirements of the permit and the provisions of this chapter. In the event of default of such and violation of any other applicable laws, such performance guaranty shall be forfeited to the Town. The Town shall return to the applicant any amount that is not needed to cover the costs of restoration, administration and any other expenses incurred by the Town as a result of the applicant's default. Such performance guaranty shall continue in full force and effect until a certificate of compliance shall have been issued by the authorized official after such consultation with any agencies or individuals as he deems necessary to ensure that all provisions of this chapter and of the permit have been met.

Variances shall only be issued upon receiving written justification of:
A showing of good and sufficient cause;
A determination that failure to grant the variance would result in exceptional hardship to the applicant; and
A determination that the granting of a variance will not result in increased runoff, erosion or sedimentation; unnecessary destruction of vegetation; additional threats to property, the environment or public safety; or extraordinary public expense or create nuisances, cause fraud on or victimization of the public or conflict with existing local laws or ordinances.
It shall be the responsibility of the authorized official or his designee to inspect the sites as frequently as necessary to assure compliance with the terms of approved permits and the provisions of this chapter.
