Construction of streets shall be in accordance with the typical
cross section of a street contained herein and the Standard Specifications for Road and Bridge Construction
(1997 edition) published by the State of Rhode Island Department of
Transportation, unless otherwise noted. Drainage systems shall be
constructed in accordance with the Standard Specifications for Drainage
Systems as adopted herein. Sidewalks and curbing shall be constructed
in accordance with the Specifications for the Installation of Sidewalks
and Curbs as adopted herein.
All soil erosion and sediment control measures required by these regulations shall be constructed in accordance with the standards and procedures set forth in the Rhode Island Soil Erosion and Sediment Control Handbook, prepared by the United States Department of Agriculture Natural Resources Conservation Service, the Rhode Island Department of Environmental Management and the Rhode Island State Conservation Committee, 1989, and any amendments thereto. (Refer to Article
XIII, §
450-52D.)
The following procedures shall be followed by the developer,
and by contractors under the direction of the developer, in the construction
of any development, subdivision, or related improvement:
A. Construction activity.
(1) No building, construction, removal of trees, or disturbance to the
land may occur on a Sunday or a holiday, as recognized by the State
of Rhode Island, in any approved subdivision or development. Hours
of construction activity are permitted only between 7:00 a.m. and
7:00 p.m. Machines shall not be left idling prior to or after this
time frame.
(2) No tree cutting, land clearing, or site grading, nor any infrastructure construction shall be permitted prior to preliminary plan approval, unless authorized by the Planning Board, and in accordance with an approved soil erosion and sediment control plan (Town Code Chapter
305). Once an application has been submitted to the Planning Board for a subdivision or development project, no building permits, nor any other pre-development construction, shall be granted until the final plan has been approved by the Planning Board and recorded in the Land Evidence Records.
(3) Proposed conservation lands and other sensitive features, such as
historic stone walls and large specimen trees, shall be adequately
protected during construction, such as including the use of fencing
and informational signage. Such protective measures, including limits
of disturbance and erosion and sedimentation controls, shall be installed
prior to the start of construction.
B. Pre-construction meeting. A pre-construction meeting shall be held
with the Director of Public Works or Highway Supervisor, the administrative
officer, and the Town's engineer at least seven days prior to the
start of any subdivision or development project improvements. The
developer (or his duly authorized representative), the developer's
engineer, and the designated on-site project manager shall attend
this meeting.
C. Construction plans. Following the pre-construction meeting, the applicant
shall submit two complete sets of construction plans, including profiles,
cross-sections, and other working drawings of required construction
improvements, to the administrative officer and to the Town's engineer.
The approval by the Town's engineer of the construction plans must
be given in writing to the administrative officer prior to any construction.
D. Notification. No step in the construction of required improvements
shall commence until the Town's engineer and administrative officer
have been notified, in writing, at least 24 hours, exclusive of Saturday,
Sunday and holidays, in advance of the beginning of the step.
E. Construction wastes and sanitation. All job sites are required to
have a dumpster, or some other method of containing debris, and a
portable toilet. Discarded building materials, concrete truck washout,
litter, and other debris shall be properly disposed of and removed
from the site. Burying or dumping of debris is prohibited. Fuel and
oil, if contained on site, shall be properly stored and contained
to prevent spills.
F. Inspection of improvements.
(1) Inspection and written approval by the Town's engineer shall be required
at several phases of subdivision improvements, including, but not
limited to:
(a)
Following installation of underground drainage and utilities,
prior to backfilling.
(b)
During preparation of subbase and with grade stakes installed
prior to the installation of gravel.
(c)
Following preparation of the subbase, backfilling and the installation
of curbing or shoulders, retaining walls, drainage structures and
site grading but prior to application of the base course.
(d)
Following spreading and compaction of the base course,
(e)
Immediately prior to and during the application and compaction
of the binder and surface course on the roadway and sidewalks.
(f)
Following completion of improvements and installation of monuments.
(g)
Immediately prior to and upon completion of any maintenance
period.
(2) The Town's engineer may require inspection subdivision improvements
or development project site improvements at such other intervals as
he/she may deem necessary to assure proper construction of improvements,
and to ensure compliance with the approved erosion and sediment control
plan.
(3) Whenever an inspection is required, the developer shall request the
Town's engineer to make such inspection. The Town's engineer or his/her
representative shall, within 48 hours, exclusive of Saturday, Sunday
and holidays, make such inspection. After consultation with the Town
Planner, Director of Public Works, Highway Supervisor or other Town
official, the Town's engineer shall give to the developer written
approval or disapproval of the improvements inspected by him/her.
Such written approval or disapproval shall become part of the permanent
record for the project. No subsequent step or phase shall commence
until an inspection has been made and approval granted.
(4) The Town may require inspections on development project sites on
an as-needed basis, and a final inspection shall be performed in order
to ensure compliance with the approved plans prior to issuance of
any certificate of occupancy.
G. As-built drawings. Upon completion of the final subgrade and drainage
infrastructure, but prior to installation of the binder course of
asphalt, the developer shall furnish three sets of certified roadway/subgrade
and drainage system as-built drawings to the administrative officer.
Upon completion of construction of all required improvements, and
before reduction to a maintenance bond, the developer shall furnish
to the administrative officer three blue-line sets and one Mylar set
of certified final as-built drawings of all improvements. The drawings
shall accurately show all features listed below as designed on approved
subdivision plans and as actually built and constructed in the field
so that all features can be located by public and private agencies.
(1) Accurate horizontal and vertical locations of:
(a)
All roads, walks, and utilities within the street right-of-way
(street plan and profile drawn at a scale of one inch equals 40 feet
horizontal and one inch equals four feet vertical).
(b)
All drainage structures, including but not limited to catch
basins, retention and/or detention basins, manholes and pipes.
(c)
All overhead utility poles, or underground power, telephone,
cable TV, and fire alarm cables and boxes.
(d)
All street lines (three-level profile) and spot driveway elevations
at street right-of-way lines and at street center lines opposite driveways.
(e)
All retaining walls, stone walls and other natural or man-made
structures, including fire cisterns and dry hydrants.
(f)
Open space improvements such as trails, ball fields, etc. as
required by the Planning Board for conservation design developments.
(2) Accurate monumentation.
(a)
All horizontal changes in direction on both sides of subdivision
streets.
(3) Plans.
(a)
Plans must be drawn to scale as required for final subdivision
plans, and shall include a title block, revision dates and reference
notes.
(b)
Plans must contain a professional land surveyor's certification
that all horizontal and vertical locations are accurate.
(c)
Plans must contain a professional engineer's certification that
all systems, including roads and utilities, will function as designed
and constructed.
Construct sidewalks when required, 42 inches wide, in accordance
with the sidewalk cross-section as detailed in Figure 1 as follows:
A. Materials. Refer to residential street construction material: §
450-62F(1).
B. Base course. Compacted depth of six inches.
C. Surface course. Compacted depth of 1 1/2 inches.
D. Observe same timing of successive steps, use limitations, and surface
preparations as outlined for steps of road construction.
Install water mains in conformance with the American Water Works
Association Standard Specifications and other specifications, as the
Kent County Water Authority may require.
Within 10 feet of adjoining property, limit changes to existing
grade to a slope of 2:1, with adequate stabilizing measures. Provide
retaining structures to contain slopes that exceed the 2:1 ratio.
Any disturbance to an existing asphalt street, including, but
not limited to, installation of public water, public sewers or natural
gas, shall require the repaving of an area not smaller than six feet
on both sides of the edges of the disturbed area, said repaving to
be from curb to curb. The intent of this section is to create areas
of transition over disturbed areas of asphalt, rather than a depressed
area or cut area of a few feet in width, deemed to be a safety hazard
to drivers.
