The Zoning Officer is designated the Floodplain Administrator. The Floodplain Administrator shall have the authority to delegate performance of certain duties to other employees.
The Floodplain Administrator is authorized and directed to administer the provisions of this Part 6. The Floodplain Administrator shall have the authority to render interpretations of this Part 6 consistent with the intent and purpose of this Part 6 and to establish policies and procedures in order to clarify the application of its provisions. Such interpretations, policies and procedures shall be consistent with the intent and purpose of this Part 6 and the flood provisions of the Building Code and shall not have the effect of waiving specific requirements without the granting of a variance pursuant to Article XLII of this Part 6.
The Floodplain Administrator shall coordinate with the Construction Official to administer and enforce the flood provisions of the Uniform Construction Code.
The duties of the Floodplain Administrator shall include but are not limited to:
A. 
Review all permit applications to determine whether proposed development is located in flood hazard areas established in Article XXXVII of this Part 6.
B. 
Require development in flood hazard areas to be reasonably safe from flooding and to be designed and constructed with methods, practices and materials that minimize flood damage.
C. 
Interpret flood hazard area boundaries and provide available flood elevation and flood hazard information.
D. 
Determine whether additional flood hazard data shall be obtained or developed.
E. 
Review required certifications and documentation specified by this Part 6 and the Building Code to determine that such certifications and documentations are complete.
F. 
Establish, in coordination with the Construction Official, written procedures for administering and documenting determinations of substantial improvement and substantial damage made pursuant to § 200-297 of this Part 6.
G. 
Coordinate with the Construction Official and others to identify and investigate damaged buildings located in flood hazard areas and inform owners of the requirement to obtain permits for repairs.
H. 
Review requests submitted to the Construction Official seeking approval to modify the strict application of the flood load and flood-resistant construction requirements of the Uniform Construction Code to determine whether such requests require consideration as a variance pursuant to Article XLII of this Part 6.
I. 
Require applicants who submit hydrologic and hydraulic engineering analyses to support permit applications to submit to FEMA the data and information necessary to maintain the Flood Insurance Rate Maps when the analyses propose to change base flood elevations, flood hazard area boundaries, or floodway designations; such submissions shall be made within six months of such data becoming available.
J. 
Require applicants who propose alteration of a watercourse to notify adjacent jurisdictions and the NJDEP Bureau of Flood Engineering, and to submit copies of such notifications to the Federal Emergency Management Agency (FEMA).
K. 
Inspect development in accordance with Article XLI of this Part 6 and inspect flood hazard areas to determine if development is undertaken without issuance of permits.
L. 
Prepare comments and recommendations for consideration when applicants seek variances in accordance with Article XLII of this Part 6.
M. 
Cite violations in accordance with Article XLIII of this Part 6.
N. 
Notify the Federal Emergency Management Agency when the corporate boundaries of the Township of West Windsor have been modified.
O. 
Permit ordinary maintenance and minor work in the regulated areas discussed in § 200-283.
The Floodplain Administrator and the applicant shall not use changed flood hazard area boundaries or base flood elevations for proposed buildings or developments unless the Floodplain Administrator or applicant has applied for a conditional letter of map revision (CLOMR) to the Flood Insurance Rate Map (FIRM) revision and has received the approval of the Federal Emergency Management Agency. A revision of the effective FIRM does not remove the related feature(s) on a flood hazard area delineation that has been promulgated by the NJDEP. A separate application must be made to the state pursuant to N.J.A.C. 7:13 for revision of a flood hazard design flood elevation, flood hazard area limit, floodway limit, and/or other related feature.
Approval of a proposed development shall not be given until the Floodplain Administrator has been provided sufficient proof that necessary permits have been granted by federal or state agencies having jurisdiction over such development, including Section 404 of the Clean Water Act.[1] In the event of conflicting agency permit requirements, the most restrictive floodplain management standards are to be imposed and reflected in the permit approval(s).

Editor's Note: Editor's Note: See 33 U.S.C. § 1344.
A. 
If design flood elevations are not specified, the Floodplain Administrator is authorized to require the applicant to either:
(1) 
Obtain, review, and reasonably utilize data available from a federal, state, or other source; or
(2) 
Determine the design flood elevation in accordance with accepted hydrologic and hydraulic engineering techniques. Such analyses shall be performed and sealed by a licensed professional engineer. Studies, analyses, and computations shall be submitted in sufficient detail to allow review and approval by the Floodplain Administrator. The accuracy of data submitted for such determination shall be the responsibility of the applicant.
B. 
It shall be the responsibility of the Floodplain Administrator to verify that the applicant's proposed best available flood hazard data area and the local design flood elevation in any development permit accurately applies the best available flood hazard data and methodologies for determining flood hazard areas and design elevations described in §§ 200-283 and 200-284, respectively. This information shall be provided to the Construction Official and documented according to § 200-298.
Base flood elevations may increase or decrease resulting from natural changes (e.g., erosion, accretion, channel migration, subsidence, uplift) or man-made physical changes (e.g., dredging, filling, excavation) affecting flooding conditions. As soon as practicable, but not later than six months after the date of a man-made change or when information about a natural change becomes available, the Floodplain Administrator shall notify the Federal Insurance Administrator of the changes by submitting technical or scientific data in accordance with 44 CFR 65.3. Such a submission is necessary so that, upon confirmation of those physical changes affecting flooding conditions, risk premium rates and floodplain management requirements will be based upon current data.
In riverine flood hazard areas where design flood elevations are specified but floodways have not been designated, the Floodplain Administrator shall not permit any new construction, substantial improvement or other development, including the placement of fill, unless the applicant submits an engineering analysis prepared by a licensed professional engineer that demonstrates that the cumulative effect of the proposed development, when combined with all other existing and anticipated flood hazard area encroachment, will not increase the design flood elevation more than 0.2 foot at any point within the community.
Prior to issuing a permit for any floodway encroachment, including fill, new construction, substantial improvements and other development or land-disturbing activity, the Floodplain Administrator shall require submission of a certification prepared by a licensed professional engineer, along with supporting technical data, that demonstrates that such development will not cause any increase in the base flood level.
A. 
Floodway revisions. A floodway encroachment that increases the level of the base flood is authorized if the applicant has applied for a conditional letter of map revision (CLOMR) to the Flood Insurance Rate Map (FIRM) and has received the approval of FEMA.
Prior to issuing a permit for any alteration or relocation of any watercourse, the Floodplain Administrator shall require the applicant to provide notification of the proposal to the appropriate authorities of all adjacent government jurisdictions, as well as the NJDEP Bureau of Flood Engineering and the Division of Land Resource Protection. A copy of the notification shall be maintained in the permit records and submitted to FEMA.
A. 
Engineering analysis. The Floodplain Administrator shall require submission of an engineering analysis prepared by a licensed professional engineer, demonstrating that the flood-carrying capacity of the altered or relocated portion of the watercourse will be maintained, neither increased nor decreased. Such watercourses shall be maintained in a manner that preserves the channel's flood-carrying capacity.
All development in riparian zones as described in N.J.A.C. 7:13 is prohibited by this Part 6 unless the applicant has received an individual or general permit or has complied with the requirements of a permit by rule or permit by certification from NJDEP Division of Land Resource Protection prior to application for a floodplain development permit and the project is compliant with all other floodplain development provisions of this Part 6. The width of the riparian zone can range between 50 and 300 feet and is determined by the attributes of the water body and designated in the New Jersey Surface Water Quality Standards, N.J.A.C. 7:9B. The portion of the riparian zone located outside of a regulated water is measured landward from the top of bank. Applicants can request a verification of the riparian zone limits or a permit applicability determination to determine state permit requirements under N.J.A.C. 7:13 from the NJDEP Division of Land Resource Protection.
When buildings and structures are damaged due to any cause, including but not limited to man-made, structural, electrical, mechanical, or natural hazard events, or are determined to be unsafe as described in N.J.A.C. 5:23; and for applications for building permits to improve buildings and structures, including alterations, movement, repair, additions, rehabilitations, renovations, ordinary maintenance and minor work, substantial improvements, repairs of substantial damage, and any other improvement of or work on such buildings and structures, the Floodplain Administrator, in coordination with the Construction Official, shall:
A. 
Estimate the market value, or require the applicant to obtain a professional appraisal prepared by a qualified independent appraiser of the market value, of the building or structure before the start of construction of the proposed work. In the case of repair, the market value of the building or structure shall be the market value before the damage occurred and before any repairs are made.
B. 
Determine and include the costs of all ordinary maintenance and minor work, as discussed in § 200-283, performed in the floodplain regulated by this Part 6 in addition to the costs of those improvements regulated by the Construction Official in substantial damage and substantial improvement calculations.
C. 
Compare the cost to perform the improvement, the cost to repair the damaged building to its predamaged condition, or the combined costs of improvements and repairs, where applicable, to the market value of the building or structure.
D. 
Determine and document whether the proposed work constitutes substantial improvement or repair of substantial damage.
E. 
Notify the applicant, in writing, when it is determined that the work constitutes substantial improvement or repair of substantial damage and that compliance with the flood-resistant construction requirements of the Building Code is required and notify the applicant, in writing, when it is determined that work does not constitute substantial improvement or repair of substantial damage. The Floodplain Administrator shall also provide all letters documenting substantial damage and compliance with flood-resistant construction requirements of the Building Code to the NJDEP Bureau of Flood Engineering.
In addition to the requirements of the Building Code and this Part 6, and regardless of any limitation on the period required for retention of public records, the Floodplain Administrator shall maintain, preserve and make available for public inspection such records as are necessary for the administration of this Part 6 and the flood provisions of the Uniform Construction Code, including Flood Insurance Studies, Flood Insurance Rate Maps; documents from FEMA that amend or revise FIRMs; NJDEP delineations, records of issuance of permits and denial of permits; records of ordinary maintenance and minor work, determinations of whether proposed work constitutes substantial improvement or repair of substantial damage; required certifications and documentation specified by the Uniform Construction Code and this Part 6, including as-built elevation certificates; notifications to adjacent communities, FEMA, and the state related to alterations of watercourses; assurance that the flood-carrying capacity of altered waterways will be maintained; documentation related to variances, including justification for issuance or denial; and records of enforcement actions taken pursuant to this Part 6 and the flood-resistant provisions of the Uniform Construction Code. The Floodplain Administrator shall also record the required elevation, determination method, and base flood elevation source used to determine the local design flood elevation in the floodplain development permit.
The Floodplain Administrator and any employee charged with the enforcement of this Part 6, while acting for the jurisdiction in good faith and without malice in the discharge of the duties required by this Part 6 or other pertinent law or ordinance, shall not thereby be rendered liable personally and is hereby relieved from personal liability for any damage accruing to persons or property as a result of any act or by reason of an act or omission in the discharge of official duties. Any suit instituted against an officer or employee because of an act performed by that officer or employee in the lawful discharge of duties and under the provisions of this Part 6 shall be defended by a legal representative of the jurisdiction until the final termination of the proceedings. The Floodplain Administrator and any subordinate shall not be liable for cost in any action, suit or proceeding that is instituted in pursuance of the provisions of this Part 6.
