On and after the effective date of this chapter,
no new street, highway or public way shall be laid out or offered
for acceptance as a public or private thoroughfare in the Town of
Bethel which does not conform to the standards and specifications
as herein provided.
[Amended 12-1-1979]
Any person, firm or corporation desiring to
lay out and construct any proposed new street, highway or public way
in the Town of Bethel shall first submit a plan for the proposed facility
to the Planning and Zoning Commission for its approval as prescribed
in Section 8-24 of the General Statutes of the State of Connecticut.
This plan shall conform to the standards set forth in the Subdivision
Regulations of the Town of Bethel as to form and content.
Before any work is commenced on a proposed roadway,
including clearing of the site, the owner shall apply for and have
issued a roadway construction permit from the Public Works Director.
The Director will supply an application form which must be completed
and returned to him with one set of roadway construction plans and
the required fee (as the same may be from time to time established
by the Public Works Commission) prior to the issuance of the permit
and start of construction. Failure to comply with the provisions of
this section shall be punishable by a fine of not less than $100,
and each day work is continued without obtaining the aforementioned
permit shall be considered a separate offense.
[Amended 12-1-1979]
All proposed streets shall be designated into
one of the following classifications by the Planning and Zoning Commission
prior to final approval:
C. Secondary high density (in sections where zoning permits
lot areas of less than 20,000 square feet).
D. Secondary low density (in sections where zoning permits
lot areas of 20,000 square feet or larger).
Storm drainage shall be provided and designed
in accordance with the following standards:
A. Pipe.
(1) Sufficient pipe shall be installed within the subdivision
to carry existing watercourses and to drain the proposed roads and/or
easements which may reasonably be expected to be constructed at some
future date on adjoining property which normally drains across the
area of the proposed subdivision or which in the opinion of the Town
Engineer would be the most practical course for such drainage. If
in his judgment there will be no substantial danger from soil erosion
or danger to the public health and safety, the Town Engineer may permit
the discharge of rivers and large streams in their natural courses
and may permit the discharge of stormwater and established watercourses
in open ditches across proposed lots of one acre or larger. All pipe
shall be of such diameter (not less than 15 inches) as will in the
judgment of the Town Engineer be sufficient to properly carry stormwater
expected to enter the pipe from the proposed subdivision and from
other properties, when developed, which normally drain across the
area of the proposed subdivision. The minimum slope for fifteen-inch
pipe shall be 0.75%.
(2) The intent of the above subsection is that pipes shall
be installed the full length in all proposed roads to permit the connection
of house storm drains and cellar drains where required by ground conditions.
B. Manholes. Manholes shall be provided at each change
in direction or grade of the pipe and shall not be spaced more than
400 feet apart. Manholes shall be constructed as shown on the standard
detail. Only precast concrete units or solid concrete blocks shall
be used.
C. Catch basins.
(1) Catch basins shall be provided in order that surface
water will not travel without interception more than as shown in the
following schedule of grades and distances:
|

|
Distance
(linear feet)

(2) Each catch basin shall be connected to a manhole or
adjacent catch basin where no manhole exists. Construction shall conform
to the standard detail. Only precast concrete units or solid concrete
blocks shall be used.
D. Underdrains.
(1) In all roadway areas where a high-water table is found
to exist, either before commencing or during actual construction of
the roadways the developer shall be required to install underdrains,
as directed by the Town Engineer or his duly authorized agent, to
protect the stability of the roadway.
(2) If required, perforated concrete or metal pipe shall
be used, backfilled with washed gravel or crushed rock 1/2 inch nominal
size to a depth of at least 12 inches over the top of the pipe. The
remainder of the trench shall be backfilled with bank-run gravel as
approved by the Town Engineer.
(3) Sufficient pitch shall be provided to allow this underground
water to run freely to a point of discharge. The size and type of
conduit shall be as directed by the Engineer.
E. Discharge. The discharge of all stormwater shall be
into suitable drainage structures of watercourses. Where the discharge
shall be onto private property within or adjoining the proposed subdivision,
proper easements and discharge rights for the Town shall be secured
by the applicant before approval of the final map and acceptance of
the drainage plan by the Planning and Zoning Commission.
[Amended 12-1-1979]
The storm drainage system shall be constructed
in accordance with the following standards and procedures:
A. Pipe. All pipe used shall be of reinforced concrete
meeting State Highway Department specifications. In some instances
the Engineer may recommend use of corrugated-metal pipe where he feels
such pipe will provide a more satisfactory drainage system.
B. Joints. The joints of all pipe shall be shoved tight.
Pipe laid in sandy, silty or other soil, where in the judgment of
the Engineer there is the possibility of silting, shall have joints
thoroughly sealed with one-to-three portland cement mortar or other
approved method.
C. Catch basins and manholes. Catch basins and manholes
shall be constructed in accordance with the approved plans. Manholes
shall be constructed of solid concrete radial manhole blocks eight
inches thick. Catch basins shall be constructed of eight-inch solid
concrete blocks.
D. Headwalls, culverts and bridges. Headwalls, culverts
and bridges shall be constructed, where required, in accordance with
good engineering practice and as specified by the Engineer. Cement
block construction will not be permitted.
E. Open ditches. Open ditches may be permitted at the
discretion of the Engineer. The waterway shall be of sufficient size
to convey all water expected to be discharged and shall be suitably
stabilized against erosion. The side banks shall be moderately sloped,
not less than three horizontal to one vertical, and then seeded or
otherwise stabilized. Paved bottom sections and riprap slopes shall
be provided when directed by the Engineer to prevent scour and erosion.
Where driveways have been constructed prior
to the petition for acceptance, said driveways shall be constructed
in accordance with the Bethel Driveway Ordinance.
Street signs shall be required at all intersections.
To insure uniformity, the developer shall pay to the municipality
the sum of $50 per required sign, and his responsibility under this
provision shall end upon payment of this sum to the Board of Selectmen.
When homes within a subdivision are occupied
prior to acceptance of the street, it shall be the responsibility
of the developer to erect mailboxes where said street intersects the
nearest public highway. The mailboxes shall be erected as directed
by the Postmaster, and they shall be maintained in good order until
the street is accepted as a public highway. The developer shall remove
same when postal service is supplied to the individual home. On a
cul-de-sac, all mailboxes shall be placed in a cluster, the location
of which shall be determined by the Director of Public Works.
When, in the opinion of the Engineer, guardrailing
is necessary to protect the traveling public, the subdivider shall
install same as directed. The guardrailing shall consist of the two-cable
variety or approved equal and shall conform to the applicable State
Highway Department specification.
Bonds for the construction of new roads and
the release thereof shall be in accordance with the Bethel Subdivision
Regulations.
The provisions of this chapter shall apply to
the construction and acceptance of all roads in the Town of Bethel,
the actual construction of which commences subsequent to the effective
date of this chapter.
The standards and specifications provided for
in this chapter shall be on file and open for inspection in the office
of the Director of Public Works.
