Applications for permits to construct or reconstruct a bulkhead
shall be accompanied with plans showing size, shape, configuration
and location of such bulkhead, and specifications of material to be
used in such construction and the manner in which such material shall
be incorporated into the bulkhead.
The location of the construction of any bulkheads shall be along
the established line thereof as shown on the Official Tax Map of the
Borough of Avalon and the finished elevation thereof shall be a minimum
of seven (7.0) feet above mean sea level based on NAVD 88 datum provided,
however, that in case of a dispute as to location, height or construction
requirements, the same shall be determined by the Construction Official.
Prior to the issuance of a Certificate of Compliance by the Borough
confirming compliance by the owner with provisions of this chapter,
the owner shall submit to the Construction Official an elevation certificate
from a licensed professional Surveyor certifying that the finished
elevation of the bulkhead is at least seven (7.0) feet above mean
sea level (NAVD 88) as required herein. Where drainage related issues

Wales shall be four inches x six inches. At least two wales will be required. A third wale shall be used where the finished top of bulkhead extends more than seven feet six inches above the existing bottom. All wale joints shall be staggered at pilings. It shall be permissible to use CCA treated materials in accordance with the specifications set forth in Subsection
a above.
c. All bolts, tie rods and spikes shall be genuine galvanized steel
of first quality. Each bolt and the rod shall be fitted with two galvanized
steel washers. Bolts and tie rods to be galvanized after threading

d. All timbers shall be set by the water jet method. Piles shall be
set on not more than five feet on center and shall be tied to anchor
piles with the tie rods previously specified. Anchor piles may be
local oak or pine and shall have a butt diameter of not less than
eight inches and a tip diameter of not less than four and one-half
(4 1/2) inches and shall not be less than twelve (12) feet in

h. Whenever a bulkhead design does not meet the specifications of this
section, then such design shall be prepared by a New Jersey Licensed
Professional Engineer and shall be in accordance with generally accepted
engineering principles and standards. It shall be the obligation of
the property owner and the owner's engineer to provide any supplemental
information which may reasonably be required by the Construction Official
and/or the Borough Engineer in order to evaluate and approve the proposed
bulkhead design. A permit shall only be issued by the Construction
Official after consultation with and review of the alternate design
by the Borough Engineer. Designs which strictly comply with this section
do not require preparation by a Professional Engineer and the same
shall come under the review responsibilities of the Construction Official.
i. The decision of the Borough Construction Official and Engineer shall
be final as to all issues related to construction material and bulkhead
design. A property owner may be entitled to a relaxation of the requirements
of this section based upon a showing of exceptional circumstances,
hardship or other good cause. The decision of the Construction Official
in such matters shall be binding unless the property owner appeals
that decision to the Borough Council. Nothing contained herein shall
be construed as limiting or attempting to limit the right of any property
owner to seek judicial review from a court of competent jurisdiction
under appropriate circumstances.
All private bulkheads within the Borough of Avalon shall be
maintained in such a manner so as to pose no danger to the health,
safety or welfare of the citizens of Avalon and so as not to pose
any threat or danger to person or property. Said bulkhead shall be
kept in such a state of repair as to prevent erosion or danger to
abutting, adjacent or adjoining properties. Whenever a bulkhead has
deteriorated to such a degree that it poses a danger, the Construction
Official shall notify the property owner, in writing, of the nature
of the deterioration and require the property owner to make necessary
repairs. The property owner shall submit a plan of corrective action
to the Construction Official not later than thirty (30) days from
receipt of the notice. Upon approval of the corrective action by the
Construction Official, the property owner shall complete all necessary
repairs forthwith. If permits are required from the State of New Jersey
or the Federal government or any agency or instrumentality thereof
and such permits are required before any work can commence, then the
property owner shall forthwith make application for all required penults
upon approval by the Borough of the property owner's corrective action
plan. In the event that a property owner fails to submit a corrective
action plan or fails to implement that plan, then, in either of such
events, the Borough may, at its option, make the necessary repairs
and charge the cost thereof to the property owner in such manner as
authorized by law.
