(d)
In lieu of the above method of finishing rolling,
the contractor may, at his option. use a vibratory method as follows:
after the material is spread evenly, so that it will have required
thickness after compaction, the entire area shall be compacted by
an approved vibratory compactor. Vibration shall continue until the
material is keyed sufficiently to permit rolling with an approved
roller without displacement of the material. For breakdown rolling
a pneumatic roller must be used.
(e)
Care shall be exercised to see that the voids
in the base course are completely filled, but the operation of vibratory
compaction shall not be such as to cause floating of the course aggregate.
(f)
The entire area shall then be rolled with an
approved roller weighing not less than 10 tons. Rolling shall begin
at the sides and continue toward the center and shall continue until
there is no movement of the course ahead of the roller.
(4)

where the horizontal distance to a natural body of water is less than
3,000 feet and land elevation at the hydrant is less than 15 feet
above the water surface.
(4)
Fire cisterns. The design and installation shall
be as shown on the Standard Detail.[5] Said fire cistern design shall include a minimum volume
capacity of 10,000 gallons unless the Fire Department and/or fire
district having jurisdiction makes a written recommendation for a
lesser capacity to the Planning Board and the Planning Board adopts
same.
[Amended 12-3-1999 by L.L. No. 33-1999]
(a)
The number of cisterns with a minimum capacity
of 10,000 gallons required per road in a subdivision is to be determined
by the following equation, rounded to the nearest whole number:
1
|
+
|
linear feet of road - 1,000 feet
| ||
---|---|---|---|---|
2,000 feet

(b)
A minimum of one cistern per road in the subdivision
is required.
C.
Special provisions for attached housing and/or multiple dwellings. All subdivisions filing under the provisions of Chapter 193 of this Code and which are to contain attached housing and/or multiple dwellings will be required to provide an adequate water supply for fire-fighting purposes as determined by this subsection. Fir-protection improvements sufficient to meet the water supply requirements, as determined below, shall be constructed.
(1)
Preliminary procedures. The applicant shall notify the Town Fire Marshal of his application, in writing, and request that a site survey be undertaken and water supply needs be calculated as described below. The applicant shall provide complete plans and drawings for all proposed structures with all dimensions and distances shown and indicating the intended occupancy and contents as indicated in Subsection C(3) below. The applicant shall notify the Town Fire Marshal, in writing, whenever any plans are made to alter any structure when such alteration would increase the total square footage of any of the structures. Again, complete plans and drawings for such alteration shall be provided as specified above.
(2)
OCCUPANCY HAZARD CLASSIFICATION NUMBER
OCCUPANCY HAZARD CLASSIFICATION NUMBER 7
STRUCTURE
Definitions. As used in Subsection C(3) below, the following terms shall have the meanings indicated:
A series of numbers from three to seven that are mathematical
factors used only in a formula to determine the total water supply
requirements for applications covered under this subsection. These
numbers are incorporated from the National Fire Protection Association
Publication No. 1231, copyright 1984. For the purposes of this regulation,
Occupancy Hazard Classification Number 7 shall be used with structure
types defined below.
Occupancies in this classification are considered light-hazard
occupancy, where quantity and combustibility of contents are low.
Fires in these occupancies can be expected to develop at a relatively
slow rate and have relatively low rates of heat release. Examples
of Occupancy Hazard Number 7 include apartments, colleges and universities,
dormitories, dwellings, hospitals, hotels and motels, libraries (except
large stockroom areas), museums, nursing and convalescent homes, offices
(including data processing), prisons and schools. This list of examples
shall not be interpreted as. being exclusive, but merely examples
of occupancy types falling within this classification.
A building erected for the support, shelter or enclosure
of persons, animals or property of any kind.
(3)
Site and structure survey. The Town Fire Marshal
shall perform a survey of all structures to be contained on the proposed
site in order to compute the total water supply required for fire-fighting
needs. The Fire Marshal shall compute the total water supply needed
in gallons as per the following:
(a)
Site areas. Where structures are close enough
in an area to be served by a single water supply, the water supply
shall be computed on the basis of the largest structure in the area.
This water supply shall not be less than 3,000 gallons.
(b)
Structures without exposure hazards. For single-
and two-family dwellings not greater than 1,200 square feet in total
area, including any attached structures, and with no portion of any
attached structural exposure hazard closer than 50 feet (unless the
attached structure is smaller than 100 square feet), the total water
supply shall not be less than 2,000 gallons. For all other structures
with no portion of any unattached structural exposure hazard closer
than 50 feet (unless the attached structure is smaller than 100 square
feet), the total water supply in gallons shall be determined by the
total cubic footage of the structure, including any attached structures,
divided by the occupancy hazard classification number. For the purposes
of this subsection, this number shall be seven as defined above. In
any event, the minimum water supply shall not be less than 2,000 gallons.
(c)
Structures with exposure hazards. For single
and two-family dwellings not greater than 1,200 square feet in total
area, including any attached structures, and with no portion of any
attached structural exposure hazard closer than 50 feet (unless the
attached structure is smaller than 100 square feet), the total water
supply shall not be less than 3,000 gallons. For all other structures
with unattached structural exposure hazards closer than 50 feet to
any portion of the structure and larger than 100 square feet, the
total water supply in gallons shall be determined by the total cubic
footage of the structure, including any attached structures, divided
by the occupancy hazard classification number determined from above
and that quotient multiplied by 1.5. The Town Fire Marshal and the
fire department or district having jurisdiction shall have the authority
to allow variances to these requirements where specific individual
conditions may require lesser amounts of water supply for exposure
protection. However, the water supply required for any structure shall
not be less than 3,000 gallons.
(d)
Water supply. The total water supply required for firefighting purposes as determined by Subsection C(3)(a), (b) and (c) above may be supplied from various sources, including wells, hydrants, cisterns, swimming pools, ponds, lakes, streams and other man-made and natural sources or a combination of such sources. Such apparatus or water supplies shall be within 1,000 feet of any and all housing clusters on the road servicing such cluster or clusters under consideration.
(e)
Post-calculation procedure. The Town Fire Marshal,
after completing the site and structure survey specified above and
computing the total water supply required, shall notify, in writing,
the appropriate fire department and/or district of the results of
the survey and of the total water supply required along with the proposed
location for such water supplies. The data submitted shall include
all calculations used to arrive at the total water supply, as well
as all plans and other backup data used for the structural site survey.
The fire department and/or district shall review said documents, and
if they meet with their approval, they shall be transmitted to the
Planning Board to be incorporated as part of the requirements for
preliminary approval of the subdivision. They shall also notify the
applicant as to the required water supplies and the location(s) of
those supplies. The fire department and/or district and the Fire Marshal
shall retain copies of all reports.
Concrete monuments shall be installed in the
locations shown on the final plat and shall be constructed according
to the details shown on the Standard Details.[1]
Trails shall be improved in the locations shown
on the final plat and shall be constructed as follows (See Standard
Details[1]):
A.
Clearing to be a minimum of four feet wide with two
feet on both sides pruned sufficiently to provide for stepping aside.
Overhead tree limbs shall be pruned to a minimum height of 12 feet
to provide for vertical clearance. Pruning will be done in accordance
with acceptable landscaping practice.
[Amended 12-3-1999 by L.L. No. 33-1999]
B.
Signs shall be placed equally along the trail.
C.
Trail warning signs consistent with the New York State
standard signs should be posted at all road crossings. (See Standard
Details for sign graphics.[2]) Directional trail markings should be posted along the
trails every 100 yards and at additional points where the trail makes
a significant turn. Directional trail markings should consist of white
paint blazes in the wooded trail areas and simple wooded arrows in
the nonwooded areas.
D.
Trails shall be at a natural grade of 5% (10% for
very short distances).
