Installation of the erosion controls shall occur
prior to earthwork on the site. The SWPPP shall be followed to ensure
the reduction or elimination of erosion and sediment loading to downstream
parcels and water bodies during construction activities.
Stormwater erosion and sediment controls are
to be inspected by a qualified professional before construction commences,
every seven days throughout construction, and within 24 hours of every
rain storm 0.5 inch or greater in accordance with the SPDES general
permit.
Vegetative, temporary and permanent structural
measures shall be used to promote overall soil and site stabilization.
The site shall be stabilized as soon as possible after disturbance
to prevent erosion, and shall be inspected and maintained throughout
construction activities, in accordance with the SWPPP.
Catch basins shall be constructed as shown in
Appendix L. Catch basins shall be constructed of precast concrete
structures. All catch basins shall be coated inside and outside with
two coats of heavy-duty coal tar sealer.
Sewer laterals and water services shall be installed
to the right-of-way (or easement) line for all lots. Each service
shall be located with a stake color-coded in conformance with Industrial
Code 53 to denote the type of service they represent.
Compaction densities specified herein shall
be the percentage of the maximum density obtainable at optimum moisture
content as determined and controlled, in accordance with AASHTO Standard
T-10, Rodded Unit Weight. Field density tests shall be made in accordance
with AASHTO Standard T-238. Each layer of backfill shall be moistened
or dried as required and shall be compacted to the following densities,
unless otherwise specified.
A. Select fill.
(1) Under all existing or proposed roads, driveways, parking
areas: 95%.
B. Methods and equipment. Methods and equipment proposed
for compaction shall be subject to the approval of the Town. Compaction
by rolling or operating heavy equipment over fill areas shall be conducted
in a manner by which injury to existing utilities and structures shall
be avoided. Any pipe or structure damaged thereby shall be replaced
or repaired as directed by the Town at the expense of the developer.
C. Testing.
(1) Field density tests may be ordered by the Town as
necessary and will be paid for by the developer.
(2) The developer shall furnish all necessary samples
for laboratory tests and shall provide assistance and cooperation
during field tests. The developer shall plan his/her operations to
allow adequate time for laboratory tests and to permit taking of field
density tests during compaction.
(3) Any areas found to be below required compaction densities
shall be removed and replaced with new material at the developer's
expense. The methods of operation and/or the backfill materials shall
be changed to meet required compactions.
(4) Inadequate compaction shall be cause for the Town
to issue a stop work order on a project.
The monuments shall be installed at those locations
shown on the approved final plan and as located in the field by a
licensed land surveyor. They shall be installed to a depth of at least
30 inches below finished grade with the top surface to be flush with
finished grade. Upon the installation of the monuments, the location
shall be certified to the Town by a licensed land surveyor as to their
accuracy.
During the time period between initial installation
and testing and acceptance for dedication, debris and/or sediment
may accumulate in the utility systems. The developer shall be responsible
to flush and remove this debris from the system prior to the final
inspection for dedication.
