Restrictions. This article is not intended to repeal, abrogate, or impair any existing ordinances, and whichever imposes the more stringent restrictions shall prevail.
Warning and disclaimer of liability. The degree of flood protection required by this article is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes. This article does not imply land outside the areas of special flood hazards or uses permitted within such areas will be free from flooding or flood damages. This article shall not create liability on the part of the Township or by any officer or employee thereof for any flood damages that result from reliance on this article or any administrative decision lawfully made hereunder.
Designation of the Township Engineer. The Township Engineer is hereby appointed to administer and implement this article by granting or denying development permit applications in accordance with its provisions.

The applicant shall give public notice of the time, place and date of the meeting at which the application will be formally presented.
The applicant will complete at least two copies of the application and submit any additional information required by the Director for review. The applicant shall also file sufficient copies of the application as directed in order to give notice to the public and for review purposes.
The applicant shall give public notice as specified by the Director's regulations to enable a review of the complete application, and the applicant shall submit proof of such notice to the Director at the public hearing. With the exception of single-family residences and additions to residences, the applicant shall, at its own cost, supply a court reporter at the public hearing and provide the Director with two copies of the transcript.
The Director may issue a regulated use permit only if he finds that the proposed use:
Has low flood damage potential; and
Does not obstruct flood flows in the floodway; and
Does not increase significantly the rate of local runoff, erosion or sedimentation; and
Does not degrade significantly the quality of surface water or the quality and quantity of groundwaters; and
Does not stress unduly the environment of the floodplain.
In reviewing the regulated use permit application and arriving at findings, the Director shall consider all of the following criteria:
The danger to life and property due to increased flood heights or velocities caused by encroachments.
The danger that materials may be swept onto other lands or downstream to the injury of others.
The proposed water supply and sanitation systems and the insulation of these systems from disease, contamination, and unsanitary conditions resulting from flooding.
The susceptibility of the proposed use to flood damage and the effects of such damage.
The duration, rate of rise, and sediment transport of floodwaters expected at the site.
The safety of access to the property in times of flood for ordinary and emergency vehicles.
The availability of alternate locations within the applicant's property not subject to flooding.
Whether the proposed use would provide adequate facilities for the proper handling of litter, trash, refuse, and sanitary and industrial wastes.
The degree to which people, animals, and property would be evacuated in the expected time available after flood warning.
The degree to which the proposed use would serve the general public's health, safety, and welfare.
The degree to which any aspect of food chain or plant, animal, fish, or human life processes would be affected adversely within or beyond the proposed use area.
The degree to which archaeological or historic sites and structures, endangered or rare species of animals or plants, high-quality wildlife habitats, scarce vegetation types, and other irreplaceable land types would be degraded or destroyed.
The degree to which the natural, scenic, and aesthetic values at the proposed activity site could be retained.
The Director shall issue a regulated use permit for the development of an improved parking area where the use is proposed to be located at an elevation equal to or greater than 173.5 feet above mean sea level.
The Director may issue a regulated use permit, may deny the permit, or may issue a permit with conditions necessary to minimize flood losses and damages to public and private property, to safeguard the public from materials being swept onto nearby or downstream lands, to protect and enhance the public's health by minimizing the degradation of stream water quality from point and non-point pollution sources, and to protect wildlife and fisheries by preserving and enhancing the environment of the floodplains. These conditions may include, but are not limited to, the following:
Where applicable, the Director shall condition regulated use permits as follows:
The Director shall make a determination of the height and extent of the fill.
Fill shall be obtained from the flood-fringe area of Parsippany-Troy Hills but preferably from the site. Fill can be obtained from other sites but preferably in the same flood basin if the applicant can prove a hardship. The Director will consider hardship applications on a case-by-case basis.
The excavation site must be drainable. (Creation of a pond is not allowed.)
Structures on fill shall be built so that the first floor and/or basements are at a minimum of one foot above the flood hazard design elevation.
Structures not placed on fill shall be otherwise elevated so that the first floor is a minimum of one foot above the flood hazard design elevation or shall be floodproofed as set forth hereinafter in Subsection L(2)(b) below. Floodproofing alone shall not be adequate for residences, hospitals, nursing homes, schools, day-care centers, and similar uses. As an alternative, structures not for occupancy by humans or animals may be protected by embankments or dikes of suitable design in the flood-fringe area.
Floodproofing. Floodproofing measures shall be consistent with the flood protection elevation for the particular area, flood velocities, durations, rates of rise, hydrostatic and hydrodynamic forces, probable evacuation time available after flood warning, and other similar factors. The Township shall require the applicant to submit a plan or document certified by a registered professional engineer or architect that the floodproofing measures are consistent with the flood hazard design elevation associated flood factors.
Installation of watertight doors, bulkheads, and shutters, or similar devices.
Reinforced walls to resist water pressures.
Use of paints, membranes, or mortars to reduce seepage of water through walls.
Addition of weight to structures to resist flotation.
Installation of pumps to lower water levels in structures.
Construction of water supply and waste treatment systems in a manner which prevents the entrance of floodwaters.
Pumping facilities, or comparable measures, for the subsurface drainage systems of buildings to relieve external foundation wall and basement flood pressures.
Construction that resists rupture or collapse caused by water pressure or floating debris.
Installation of valves or controls on sanitary and storm drains which will permit the drains to be closed to prevent backup of sewage or stormwaters into the structure. Gravity drainage of basements may be eliminated by mechanical devices.
Location of all electrical equipment, circuits and installed electrical appliances in a manner which will assure they are not subject to inundation and flooding.
Adequate emergency electrical power supplies.
Storage and processing facilities. Chemicals, explosives, buoyant materials, flammable liquids, petroleum products, or other hazardous materials shall be situated above the flood hazard design elevation or shall be protected by suitable dikes or embankments. Furthermore, these facilities shall be designed, constructed and operated in a manner to prevent flotation of storage containers which would result in the escape of hazardous materials into the floodwaters.
State and/or federal regulations. In any case, conformance must be made with the latest state and/or federal regulations, whichever is the most stringent.
Regulated use permits may be revoked for any violation of the flood-fringe area regulations or for the violation of any permit conditions.
Notification of decision.
The Director shall not decide on an application until the interested parties have had an opportunity to submit comments on the application.
The Director shall notify the applicant in writing as to the granting, conditioning or denying of a regulated use permit. The reason for the decision shall be stated in writing as part of this notification.
At the same time that notification is provided to the applicant, a copy of the same notification shall be provided to each party who submitted comments on the application.
Preexisting structures and uses. This article requires that:
Structures which lawfully existed on or before the effective date of the regulations are permitted to remain subject to the following conditions:
Maintenance and repair of preexisting structures are permitted and do not require a regulated use permit.
No preexisting structure shall be enlarged greater than 200 square feet without a regulated use permit being granted.
If a preexisting structure is damaged by any means, including floods, it may be repaired or restored to its condition prior to such damage. If such a structure is destroyed beyond repair, it shall not be reconstructed unless a regulated use permit has been granted.
In the event of a "start of construction" on or before the effective date of the regulations, then the structure may be completed without a regulated use permit.
Uses of land or structure which lawfully existed immediately before the effective date of the regulations are permitted to continue subject to the following:
No preexisting use shall be expanded or enlarged greater than 200 square feet unless a regulated use permit has been granted.
No preexisting use shall be modified so as to increase its flood damage potential, unless a regulated use permit has been applied for and received.
Sanitary landfills are prohibited from expanding horizontally. They may be permitted, however, to expand vertically if they comply with all other applicable provisions of law and if their flood hazard potential is not increased.
Maintenance and repair.
Maintenance and repair of a structure are permitted and shall not require additional regulated use permits. Maintenance, repair, and replacement shall comply with the terms of the original permit.
If a structure for which a regulated use permit has been granted is destroyed by floods and is beyond repair, the structure shall not be reconstructed unless a new regulated use permit has been applied for and received. If the structure is destroyed by any means other than floods, it may be reconstructed without applying for an additional regulated use permit. Reconstruction shall comply with the terms of the original permit.
Supplemental flood hazard area delineations. If the Township determines that lands within its jurisdiction, in addition to those delineated by the Council, should be included within the flood hazard area because improper development and use of these lands would constitute a threat to the public safety, health, and welfare, the municipality may present its delineation to the Council, with documentation as may be required by the Council, for consideration and possible adoption.
The powers, duties, and functions vested in the municipality under the provisions of the Act or these standards shall not be construed to limit in any manner the powers, duties, and functions vested therein under any other provisions of law.
[Adopted by Ord. No. 92:16]
No person shall attempt to operate, close or open the flood gates at the Lake Hiawatha Flood Project except after notification to the Director of the Department of Public Works or his authorized and designated representative.
[Amended 12-20-2005 by Ord. No. 2005:31]
Between April 15 and October 1 of each year, the flood gates shall remain open at all times, except when, in the opinion of the Director of the Department of Public Works or his authorized and designated representative, there is a need to close same because of possible flooding.
After the Lake Hiawatha Swim Club has been closed and secured for the winter season, the gates shall remain closed, except that the gate or gates will be opened for the convenience of the Lake Hiawatha Swim Club upon notification to the Director of the Department of Public Works; and thereafter, the gates shall be closed and secured by whomever opened same.
