B.
The construction, use, maintenance or continued existence of any illicit connection, as defined in § 124-2 above, to the storm drainage system is prohibited. This prohibition expressly includes, without limitation, illicit connections made prior to the effective date of § 124-2, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection.
C.
Residential stormwater connections which discharge from indoor drains into the City's stormwater drainage system or sanitary sewer system, and which existed prior to the effective date of the permit system in § 124-4, may be permitted at the discretion of the City Manager if the following standards are met, and if the permit is otherwise consistent with the purposes of this chapter. Applicants seeking authorization for approval of existing presently unpermitted stormwater connections or those removing indoor drains from the sanitary sewer system with the intent of connecting into the stormwater drainage system will not be required to satisfy the capacity analysis provisions of § 124-4A(5), as long as all of the following standards are met:
(1)
The amount of impermeable surface will not be increased on the property
resulting in increased stormwater flow.
(2)
The applicant will be required to construct adequate berms, sumps
or other measures in such a way as to reduce the risks of contaminants
in or on the structure from entering the stormwater drainage system.
(3)
The applicant shall be required to demonstrate that all facilities
such as oil tanks or other structures are adequately secured such
that they do not become buoyant and present a risk of spill and resultant
discharge of contaminants into the indoor drain which is connected
to the stormwater drainage system.
(4)
Connections to the stormwater drainage system shall be equipped with
backflow prevention devices such as in-line check valves to protect
the property from backflow from the stormwater drainage system.
A.
Stormwater permit. There is, as established by the Code of the City of Lebanon, Chapter 68, a stormwater connection permit application fee for all users of the City of Lebanon stormwater drainage system. The fee shall be waived for all stormwater connections which are disconnecting an existing stormwater connection, including all indoor drains, from the sanitary sewer system. This application fee herein shall apply to all persons whose premises stormwater enters the public stormwater drainage system of the City of Lebanon, subject to the exceptions detailed in § 124-3A above.
(1)
Each connection shall be separately assessed to the owner(s) of land
being benefited thereby regardless of whether that land has more than
one connection to the City's public stormwater drainage system. The
application fee set forth herein is a one-time charge to offset the
administrative costs of the application process.
(2)
Application fees shall be paid upon submission of application for
a stormwater connection permit. This fee is non-refundable regardless
of whether a stormwater connection permit is issued or not.
(3)
No person shall connect to the stormwater drainage system unless
the City has issued a permit for such connection.
(4)
Any person seeking such a permit to connect to the stormwater drainage
system (the applicant) shall make application on a form furnished
by the City. The permit application shall be supplemented by any plans,
specifications, engineering studies or other information considered
pertinent in the judgment of the Director of Public Works. Such supplemental
information will be supplied at the applicant's cost.
(5)
The Director of Public Works shall review the service data to determine
whether it has sufficient capacity to provide stormwater drainage
service to the applicant.
(a)
The applicant shall have the burden of presenting sufficient
information, based on such engineering data as deemed necessary by
the Director of Public Works, to demonstrate the following:
[Amended 9-7-2022 by Ord. No. 2022-03]
[1]
Sufficient measures will be implemented to control the post-development
peak rate runoff so that it does not exceed pre-development runoff.
The drainage analysis should be practical for the site, fiscally responsible,
and shall include calculations comparing pre- and post-development
stormwater runoff rates (cubic feet/second) and volumes (cubic feet)
for the two-, twenty-five-, fifty-year and one-hundred year twenty-four-hour
storm events.
[2]
To the extent that on-site control measures are insufficient at keeping the postdevelopment peak flow rate at or below the existing peak flow rate, a stormwater study will be required to show that, at a minimum, all affected elements of the City's Stormwater system have sufficient capacity for such discharges. In such cases, the applicant shall be permitted to discharge a peak flowrate for the twenty-five-year storm frequency amount not to exceed 50% of the remaining capacity of the receiving stormwater system. Culverts and storm sewers shall be able to pass the one-hundred-year twenty-four-hour storm event without overtopping and roadway ditches shall be required to pass the twenty-five year twenty four hour storm event without overtopping. In either case the applicant shall be responsible for all costs incurred by the City in making a determination of sufficient capacity except as outlined above in § 124-3C.
[3]
Every applicant shall provide for stormwater management as required
by these Regulations, unless a waiver is granted pursuant to this
section. Waiver requests shall be submitted in writing to the Director
of Public Works, who may waive the minimum requirements for stormwater
management in whole or in part, provided that the following conditions
apply:
[a]
The granting of the waiver will not be detrimental to the public
safety, health, or welfare or injurious to other property;
[b]
The conditions upon which the request for a waiver is based are unique
to the property for which the waiver is sought and are not applicable
generally to other property;
[c]
Because of the particular physical surroundings, shape or topographical
conditions of the specific property involved, a particular hardship
to implement a particular BMP (Best Management Practice) to the owner
would result, as distinguished from a mere inconvenience, if the strict
letter of these regulations are carried out;
[d]
The granting of the waiver will not be contrary to the spirit and
intent of the regulations; and,
(b)
If the Director of Public Works determines that the City's stormwater
drainage system does not or will not have sufficient capacity to serve,
he/she shall not be obligated to provide the service. The City Manager
may, at his/her option and discretion, enter into such agreements
with applicant to make readiness to serve improvements at the applicant's
expense.
(c)
If the City Manager determines, based on input from the Director
of Public Works that there is sufficient capacity to provide adequate
service, the City Manager may approve the service.
[Amended 9-7-2022 by Ord. No. 2022-03]
(d)
Service shall not be provided until all required deposits or
payments have been made by the applicant.
(6)
All costs and expenses incident to the installation and connection
to the stormwater drainage system shall be borne by the applicant.
The applicant shall indemnify the City from any loss or damage that
may directly or indirectly be occasioned by the installation of the
connection to the stormwater drainage system.
(7)
The method of connection to the stormwater drainage system shall
be acceptable to the Director of Public Works and shall conform to
the requirements of all applicable building and plumbing codes, Public
Works Department specifications or to other applicable rules and regulations.
(8)
The applicant shall notify the Director of Public Works when the
connection to the stormwater drainage system is ready for inspection
and connection to the stormwater drainage system. The connection shall
be made under the supervision of the Director of Public Works or his/her
designee. No back-filling shall occur prior to inspection.
(9)
All excavations for connections to the stormwater drainage system
shall be adequately guarded with barricades and lights and so as to
protect the public from hazard. Streets, sidewalks, parkways and other
public property disturbed in the course of the work shall be restored
in a manner satisfactory to the City. Prior to any excavating on any
public property, an excavation permit must be obtained from the Department
of Public Works. This provision does not relieve any person from any
applicable state or federal laws or regulations relating to excavation.
(10)
Connection to the stormwater drainage system is at the person's
own risk.
(11)
Any person connected to the stormwater drainage system shall
be responsible for the ownership and maintenance of the stormwater
conveyance extending from the premises to the stormwater drainage
system and all equipment and devices as approved by the permit.
B.
Stormwater extensions. Extensions of the stormwater drainage system
within the City of Lebanon shall require the approval of the City
Manager. All extensions of the stormwater drainage system shall, in
addition, require the issuance of a stormwater connection permit in
accordance with this chapter.
(1)
Upon a request by a property owner or a developer(s) for the extension
of the stormwater drainage system the City Manager shall make a determination
upon the request and shall base his/her decision upon:
(2)
All requests for extensions of the stormwater drainage system as
proposed by a developer shall require an extension agreement between
the City and the developer containing the following:
(a)
The developer shall pay the full cost of design and construction
of the extension in accordance with City standards and requirements.
All plans for the design of the extension shall be submitted to the
City Engineer or such other person as designated by the Public Works
Director, for written approval. Any cost incurred by the City in reviewing
the design shall be paid for by the developer.
(b)
The developer shall pay to the City, prior to any construction,
an amount estimated by the City to pay for independent engineering
inspection services hired by the City. The applicant shall keep a
minimum $2,500 balance in escrow. If the City spends less than the
amount paid by the developer, the balance shall be refunded to the
developer. If the City spends more than the payment made by the developer,
the developer shall reimburse the City. The City's review of the construction
documents and inspection during the period of construction and inspection
prior to acceptance shall not bar or preclude, in any way, the rights
of the City to assert claims against the developer for defects in
construction.
(3)
The developer shall provide indemnification to the City for any costs,
damages or other expenses arising from review or construction of the
extension.
(4)
If any portion of the proposed extension is not within a City highway,
the developer shall acquire and convey to the City, as a condition
of acceptance of the extension, adequate rights-of-way in compliance
with the City's requirements and in conformity with the requirements
of the City as to the form of the deed, a title opinion, monuments
and a recordable plan.
(5)
After the extension has been substantially completed, as certified
by the City Engineer or other such person as designated by the Director
of Public Works, the developer shall be responsible to repair and
maintain the extension for a period of one year or until such time
as the City's acceptance of the extension improvements is complete.
(6)
After the expiration of the one-year period for maintenance, the
City Manager shall determine whether or not to issue a certification
that the extension has been constructed and installed in accordance
with the plans, specifications and standards of the City. The City
Manager may require a report of a professional engineer, hired by
the City and paid for by the developer.
(7)
It shall be a condition of the extension agreement and any City acceptance
that the developer shall be responsible for any latent defects discovered
within eight years from the date of substantial completion, as set
forth in RSA 508:4-b, including all defects in design, materials or
workmanship, and shall be liable to the City, upon written notice
by the City, for the cost of repairs or replacements of all defective
improvements. In the event that the developer conveys and transfers
the project for which the extension was granted, the subsequent owner
shall be responsible for the obligations of the developer for the
remainder of the eight-year period regardless of whether or not such
obligation is expressly assumed.
(8)
No additional connections to the extension will be allowed for any
other property owners requesting service for a period of 10 years
from the date of acceptance of the extension by the City unless such
property owner(s) agree to pay to the developer a pro rata share of
the cost relating to the extension as determined by the City Manager.
The developer shall provide a copy of the contract documents for the
construction of the extension to the City prior to undertaking any
construction for review and approval by the City to ensure that the
requirements of the extension agreement have been met. The developer
shall include in any construction documents that the proposed extension
is intended to be transferred to the City for ownership and maintenance.
The City Manager shall determine the pro rata share of cost to new
applicants seeking connection to the extension based on the following
criteria:
(a)
The depreciated value of the extension infrastructure paid for
by the developer at the time the new applicant utilizes the extension.
(b)
The percentage of the extension at the point at which the new
connector accesses the connection; in essence, how much of the new
extension is the connecting applicant utilizing. In addition, any
security or bond obtained by the contractor constructing and installing
the extension for the benefit of the developer shall remain in effect
until the expiration of a two-year period from the date the project
is accepted by the City and shall be for the benefit of the City.
(9)
Upon compliance with all the conditions set forth herein, the developer
may request and the City Manager shall accept the transfer of the
extension, including the stormwater drainage conveyances and rights-of-way
to the City to become part of the City stormwater drainage system
and the responsibility of the City thereafter.
A.
Right of entry on all property. The Director of Public Works and
other duly authorized employees of the City bearing proper credentials
and identification shall be permitted to enter all properties for
the purposes of inspection, observation, measurement, sampling and
testing pertinent to discharge to the stormwater drainage system in
accordance with the provisions of this chapter, and shall have authority
to investigate potential violations of this chapter. Before entering
any property for such purpose, the Director of Public Works or his/her
agent shall first seek the consent of the owner of the property, or
other party with a legal right to control access. In the event such
consent is withheld or cannot be obtained within a reasonable period
of time, the Director of Public Works shall have the authority to
seek an administrative inspection warrant pursuant to RSA Ch. 595-B;
provided, however, that an application for a connection or extension
permit under this chapter shall be presumed to grant permission to
City personnel to enter the property for all purposes pertaining to
that permit application.
B.
Liability. While performing the necessary work on private properties referred to in Subsection A, Rights of entry on all property, above, the Director of Public Works or duly authorized employees of the City shall observe all safety rules applicable to the premises established by the user, and the user shall be held harmless by the City for injury or death to the City employees, and the City shall indemnify the user against loss or damage to its property by City employees and against liability claims and demands for personal injury or property damage asserted against the user and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the user to maintain safe conditions, right of entry for inspection and sampling, of this chapter.
C.
Right of entry on private property; easements. The Director of Public
Works and other duly authorized employees of the City bearing proper
credentials and identification shall be permitted to enter all private
properties through which the City holds an easement for the purposes
of, but not limited to, inspection, observation, measurement, sampling,
repair and maintenance of any portion of the stormwater facilities
lying within said easement. All entry and subsequent work, if any,
on said easement, shall be done in full accordance with the terms
of the easement.
A.
In the event the Director of Public Works determines that a property
is in violation of this chapter, the Director may issue a written
notice of violation by certified mail to the property owner; provided,
however, that nothing herein shall prevent the City, in emergency
circumstances where the delay entailed by the notice process could
result in a danger to health, safety or the environment, from commencing
an enforcement action without such a notice of violation. Any such
notice of violation shall:
(1)
Specify the actions or conditions that constitute the violation;
(2)
Identify any action required to be taken in order to correct the
violation(s);
(3)
Establish a reasonable time frame for remedying the violation;
(4)
Notify the owner of record of the City's right to commence an enforcement
action, which may include a request for fines, civil penalties, and/or
injunctive relief.
B.
As an alternative to a notice of violation under Subsection A above, the Director of Public Works may, in cases involving a potential danger to public health, request the City's Health Officer to issue an order under RSA Ch. 147, which may include provision for the abatement of the violation by the City, and collection of the City's abatement and other costs, using the procedures set forth in RSA 147:7-a and RSA 147:7-b.
A.
The City may enforce the provisions of this Chapter by means of legal
action, seeking any or all remedies and penalties consistent with
state law, including but not limited to fines of up to $1,000 pursuant
to RSA 47:17, civil penalties of up to $10,000 per day of violation
pursuant to RSA 149-I:6, and/or injunctive relief. In any legal action
brought by the City to enforce this chapter, the City shall be entitled
to recover its costs and reasonable attorney fees expended in connection
with any such enforcement action if found to be a prevailing party.
B.
Assessment of repair charges. Any person who causes a discharge which
obstructs, damages or otherwise impairs the stormwater drainage system
may be assessed a charge by the City for the work required to repair
or clean the affected facilities.
C.
False statements and inaccurate information. Any person who knowingly
makes any false statements, representation, record, reports, plan
or other document filed with the City or who falsifies, tampers with
or knowingly renders inaccurate any monitoring device or method required
under this chapter shall be punished by a civil penalty of not more
than $10,000.
D.
Malicious injury; penalty. In accordance with RSA 149-I:23, any person(s)
who shall wantonly or maliciously (purposely or knowingly) injure
any part of any stormwater drainage system, conveyance, and discharge
system, or sewage disposal plant shall be liable for pay treble damages
to the owner thereof, and shall be guilty of a misdemeanor if a natural
person, or a felony if any other person.
