It is the purpose of this chapter to protect public health, safety and
welfare in the Town of Highlands by regulating site preparation and construction
activities, including excavation, filling, grading, stripping and construction
of drainage facilities so as to prevent problems related to erosion, sediment
or drainage. In relation to this purpose this chapter is intended to:
A. Preserve the quality of the natural environment from
such adverse effects of site preparation and construction as:
(1) Pollution of lakes, ponds and watercourses from silt
or other materials;
(2) Unnecessary destruction of trees and other vegetation;
(3) Excessive exposure of soil to erosion;
(4) Unnecessary modification of natural topography or unique
geological features; and
(5) Failure to restore sites to an attractive natural condition.
B. Protect people and properties from such adverse effects
of site preparation and construction as:
(1) Increased runoff, erosion and sediment;
(2) Increased threat to life and property from flooding or
storm waters;
(3) Increased slope instability and hazards from land slides
and slumping; and
(4) Modifications of the groundwater regime that adversely
affect wells and surface water levels.
C. Protect the Town and other governmental bodies from having
to undertake, at public expense, programs of repairing roads and other public
facilities, of providing flood protection facilities and of compensating private
property owners for the destruction of properties arising from the adverse
effects of site preparation and construction; and
D. Ensure that site preparation and construction are consistent
with the Comprehensive Plan of the Town of Highlands.
In accordance with Article 9 of the Town Law of the State of New York,
the Town of Highlands has the authority to enact local laws for the purpose
of promoting the health, safety or general welfare of the Town of Highlands,
including the protection and preservation of the property of its inhabitants.
By the same authority the Town of Highlands may include in any such chapter
provision for the appointment of any municipal officers or employees to effectuate
and administer such ordinance.
In order that site preparation and construction activities may be in
conformance with the provisions of this chapter, this chapter is hereby adopted
and shall be known and may be cited as the "Erosion, Sediment and Drainage
Control Local Law of the Town of Highlands."
Upon the adoption of this chapter, all site preparation and construction
activities requiring a permit under this chapter shall be in conformance with
the provisions set forth herein.
Where this chapter imposes greater restrictions than are imposed by
the provision of any law, ordinance, regulation or private agreement, this
chapter shall control. Where greater restrictions are imposed by law, ordinance,
regulation or private agreement than are imposed by this chapter, such greater
restrictions shall control.

[Added 5-22-2006 by L.L. No. 2-2006]
In granting a permit under this chapter, the standards and considerations
taken into account include but shall not be limited to the following:
A. Excavation, filling, grading and stripping 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.
B. 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.
C. The control of erosion and sediment shall be a continuous
process undertaken as necessary prior to, during and after site preparation
and construction.
D. The smallest practical area of land shall be exposed
by site preparation at any given time.
E. 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.
F. Mulching or temporary vegetation suitable to the site
shall be used where necessary to protect areas exposed by site preparation
and permanent vegetation which is well adapted to the site shall be installed
as soon as practical.
G. Where slopes are to be revegetated in areas exposed by
site preparation, the slopes shall not be of such steepness that vegetation
cannot be readily established or that problems of erosion or sediment may
result.
H. Site preparation and construction shall not adversely
affect the free flow of water by encroaching on, blocking or restricting watercourses.
I. All fill material shall be of a composition suitable
for the ultimate use of the fill, free of rubbish and carefully restricted
in its contents of brush, stumps, tree debris, rocks, frozen material and
soft or easily compressible material.
J. Fill material shall be compacted sufficiently to prevent
problems of erosion and where the material is to support structures, it shall
be compacted to a minimum of 90% of standard proctor with proper moisture
control.
K. 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.
L. 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.
M. 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.
N. All drainage systems shall be designed to handle adequately
anticipated flows both within the site and from the entire upstream drainage
basin.
O. 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.
P. There shall be provided where necessary to minimize erosion
and sediment such measures as benches, berms, terraces, diversions and sediment,
debris and retention of basins.
Q. Drainage systems, plantings and other erosions 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.
R. Tree removal or destruction shall be permitted if the presence
of trees would cause hardship preventing the reasonable use of the property
for approved or permitted purposes, which hardship is not self-created and
is unique to the property; or endanger the public or the person or property
of the owner or neighbors; or the trees are on property to be occupied by
buildings, structures or related improvements and within a distance of 10
feet around the perimeter of such building or structure; or block an important
viewshed and the removal of the trees is performed in a selective manner.
Other considerations may include the likelihood of the survival of the tree,
economical considerations of land use, the general welfare and the overall
environment of the area, whether the removal will have significant adverse
impact on ecological systems, including erosion potential and wildlife habitat,
and whether the removal will have significant adverse impact on other properties
or roadways, including impacts on drainage. The Planning Board may require
proposed buildings or structures to be relocated on a plan or reduced in size
in order to save a tree or trees which the Planning Board determines to be
important or whose removal will have significant adverse impact.
[Added 5-22-2006 by L.L. No. 2-2006]
S. During site preparation activities, the property owner or developer
shall protect all trees on the approved subdivision plat, site plan and/or
permit map, as the case may be, designated to be preserved by the Planning
Board.
[Added 5-22-2006 by L.L. No. 2-2006]
(1) Unless the Planning Board, for good cause, determines otherwise,
all trees designated to be preserved by the Planning Board shall be guarded
as follows: (1) for trees with a crown spread of eight feet or less, a substantial
fence, frame or box not less than four feet high and eight feet square shall
surround the tree; (2) for a tree with a crown spread over eight feet, a fence
not less than four feet high shall be placed at least at the tree's dripline
marking the outer edges of the branches or at a distance otherwise prescribed
by the Planning Board.
(2) Fencing shall, at a minimum, be constructed of orange nylon-type material and stakes. The authorized official may approve other suitable fencing. Fencing and other barriers shall be erected before site preparation begins and remain in place until granting of the certificate of occupancy, except for work specifically required in the tree protection area in the approved plans. The owner or contractor shall submit written verification to the Building Inspector that required tree barriers are in place prior to demolition or building permit issuance. Every effort to avoid compaction of soil porosity within the tree protection area shall be taken at all times as mitigation against injury. All building material, soil or debris shall be kept outside these barriers, and water shall not be permitted to accumulate near the base of the tree. Roads and driveways shall be located as far from protected tree areas as possible. If a temporary driveway is needed in the root zone of a protected tree, 12 inches of wood chips shall be used as a base for the equipment to drive on. Such trees shall not be damaged during site preparation activities or removed without the prior consent of the Planning Board. In the event that such trees are damaged during site preparation activities or removed without prior consent of the Planning Board, such trees shall be replaced by trees the size and species of which are to be determined by the Planning Board, which trees shall be guaranteed and maintained for a period of two years. Unless the Planning Board, for good cause, determines otherwise, damaged, destroyed or removed protected trees shall be replaced by the caliper inch, such that for every inch of diameter (DBH) removed, an equal number of caliper inches shall be replaced (for example, the unauthorized removal of one twelve-inch DBH tree shall necessitate the planting of six two-inch DBH trees or four three-inch DBH trees, etc.). No site plan approval, special permit, building permit, certificate of occupancy, variance, or other Town permit shall be issued by any Town agency for said property until such replacement has been completed and approved by the authorized official, and the Planning Board may revoke the existing permit in accordance with the provisions of §
101-8J.
