All driveways shall be located, designed and constructed
in such a manner as not to interfere or be inconsistent with the design,
maintenance and drainage of the highway.
(6)
Frontages of 100 feet or less shall be limited to
one driveway. Normally not more than two driveways need to be provided
to any single property tract or business establishment. Exceptions
may be made where the frontages exceeds 300 feet in length or where
the internal vehicular pattern requires.
(7)
Provisions for drainage and stormwater runoff shall
be approved by the Township Engineer.
(8)
Where a property abuts a state, county or Township
right-of-way and where a driveway extends from that right-of-way to
the interior of the property, the applicant must obtain a permit from
PennDOT, Montgomery County or the Township indicating compliance with
all applicable standards and criteria.
B.
Construction standards.
(1)
Single-family residential developments. The driveways
and parking areas for a single-family residential development shall
have a thickness of not less than six inches, the base of which shall
consist of four inches base course of 2A modified stone as compacted,
and a surface which shall be two inches compacted thickness of ID-2A
wearing course. The paving shall be constructed both as to materials
and workmanship in accordance with specifications and standards promulgated
by the Pennsylvania Department of Transportation now in force or hereafter
revised and on an approved firm subgrade.
(2)
Multifamily, commercial and industrial driveways and
parking areas. All driveways and parking areas in multifamily dwellings,
commercial and industrial areas shall have a thickness not less than
10 1/2 inches, the base of which shall consist of two layers
of crushed aggregate base course (PennDOT standard) as compacted and
a surface of which shall be 1 1/2 inches of ID-2A binder course
and one-inch ID-2A surface course as compacted. The paving shall be
constructed both as to materials and workmanship in accordance with
specifications and standards promulgated by the Pennsylvania Department
of Transportation now in force or hereafter revised and on an approved
firm subgrade.
C.
Construction inspection.
(1)
The construction of all driveways and parking areas
will be subject to the inspection and approval of the Township. The
Township shall be notified a minimum of 48 hours in advance of construction.
(2)
Failure to follow these rules and regulations will
prevent use and occupancy of the structure until it can be proven
that the driveway was constructed properly.
[Adopted 2-10-1987 by Ord. No. 87-1]
It is the purpose of this article to prevent
and, where existing, to alleviate blockages of or impediments to the
flow of surface water along public roads due to the existence of private
lanes or driveways opening onto such public roads. Further, this article's
purpose is to prevent surface water issuing from such private lanes
and driveways from entering onto or otherwise deleteriously affecting
the integrity or safety of such public roads.
Every private lane or driveway constructed after
the date of this article shall, at its intersection with a public
road, have such drains, culverts, gutters or other devices for the
purpose of facilitating storm drainage as the Township or its authorized
agent shall determine to be required.
A.
Where a driveway or private lane slopes downward toward
its intersection with a public road, a structure shall be installed
to intercept and collect the rainwater runoff from the driveway. In
general, this structure shall be located at the point of intersection
of the driveway and the roadside drainage swale; however, where special
circumstances so dictate, the Township may require a different location.
B.
Drainage interceptor structures shall be of the following
three types:
(1)
Type A: concrete trench drain with welded steel crate.
(2)
Type B: slotted drainpipe.
(3)
Type C: concrete epoxy prefabricated drain trench.
(4)
Type of structure to be used shall be according to
Appendix Table 1. Construction details shall be as shown in appendix.[1]
[1]
Editor's Note: Appendix Table 1 and Detail Drawings are included at the end of this chapter.
C.
Where driveways are level with the road surface or
slope downward away from the road, a standard culvert of corrugated
steel pipe, reinforced concrete pipe, or similar material approved
by Township shall be used at roadway swale. Size shall be as required
by Township to carry the flow in roadway swale, or such larger size
as may be required by swale invert elevation.
D.
Where the Township determines that groundwater seepage
from a property will cause moisture problems in the roadway base,
subsurface drains shall be installed. No additional measures are required
if the driveway utilizes Type A or C interceptors. Where either a
slotted drainpipe or a standard drainage culvert is to be used, said
pipe or culvert shall be perforated and bedded in six inches of Type
2B crushed aggregate. Where an existing unperforated culvert is presently
installed, an aggregate trench drain may be installed on the property
owner's side of the existing culvert, constructed as shown in the
detail drawings at the end of this chapter.
E.
Minimum length for all driveway entrance culverts
or other structures shall be 27 feet.
F.
The Township may, at its sole discretion, waive the requirement for a Type A, B or C structure and allow the driveway to be constructed with a standard culvert as in Subsection C above and a swale constructed across the driveway to intercept runoff. Such waiver shall only be allowed under the following conditions:
(1)
Maximum slope of driveway is 5% for a distance of
50 feet from roadway swale.
(2)
Applicant can demonstrate to Township's satisfaction
that the cross-swale can be effectively constructed and drained away
from the driveway in a manner which will not fill up and eliminate
the swale.
(3)
Swale, when constructed, shall have sides with a maximum
slope of 12.5%, and a minimum depth of two feet below the intersection
of the drive with the roadway.
(4)
Swale invert shall be minimum of 15 feet from roadway
edge.
In the case of any new private lane or driveway
opening onto a Township road, the person constructing such driveway
shall first obtain from the Township a permit for road occupancy.
This permit shall state the requirements to be met by the driveway
at its intersection with the roadway, including, but not limited to,
location, type of drainage device(s) and time limits for the work
to be completed.
A.
The obtaining of such permit and the installation
of the required drainage device(s) shall be a precondition to the
issuance of a zoning permit for any new building or structure served
by the new driveway.
B.
The Township may, at its sole discretion, waive this
precondition so as to permit the installation of the drainage device(s)
to be delayed until the possibility of damage by construction equipment
is past. In such case, the applicant shall post with the Township
financial security sufficient, in the Township's opinion, to defray
costs of construction if applicant should fail to construct the required
improvements. Such financial security shall be in the form of an escrow
account, a letter of credit or such other instrument as the Township
shall find acceptable.
Every owner of a private driveway or lane opening
upon the public roads of Upper Hanover Township shall, upon written
notice from the Board of Supervisors, construct, install, alter or
reconstruct such conduits, drains, interceptors or gutters required
to correct the drainage problem referred to in the notice. Such repair
or reconstruction shall include the installation of the above-mentioned
improvements and/or the alteration of grades and lines of the drive
or lane and shall be done to the specifications of the Township or
its authorized agent.
Written notice shall be given to all affected
property owners to construct, reconstruct or install drainage facilities
under or around their private driveways. Service of notice shall be
considered as made on the date when said written notice is either
mailed to said owners, if they be known, or posted on the premises
of said owners or published in a newspaper of general circulation
in the Township. Said notice shall include a statement of the times
and place at which said owner may obtain from the Township the specifications,
line and grade of the pipes, drains and gutters required to be installed.
If any owner of a private lane or driveway shall
fail to construct or to arrange with the Township to construct pipes,
gutters, conduits or drains within 90 days of service of notice to
do so, the Township of Upper Hanover may construct or cause the same
to be constructed and charge the cost thereof to the owner of the
lane or driveway, along with any additional penalty authorized by
law.
The cost of any such construction or installation
done by the Township of Upper Hanover shall be a lien upon the premises
from the time of the commencement of the work. Any such lien may be
collected by an action in assumpsit or by lien filed in the manner
provided by law for filing and collection of municipal claims.
Any person who shall fail, neglect or refuse
or cause any person to fail, neglect or refuse to comply with any
of the terms or provisions of this article shall, upon conviction
thereof before any Magisterial District Judge, be sentenced to pay
costs and a fine not exceeding $300 or to imprisonment in the county
jail for a term not to exceed 30 days for each offense, or to both
such fine or imprisonment.
