<br />Design Oevelopment
<br />
<br />General designs were developed for five buildings which
<br />could accommodate the space needs, Variation among
<br />building types was confined to their floodproofing fea-
<br />tures in order to clarify the comparisons of their relative
<br />costs and benefits,
<br />
<br />The basic design was for a commercial structure of con-
<br />ventional construction, having no special treatment with
<br />respect to flood hazards, to provide a basis of compari'
<br />son for evaluating the costs and benefits of fiood proofed
<br />structures, The second design was for a "wet flood
<br />proofed" structure at grade, This structure would admit
<br />flood waters, equalizing interior and exterior hydrostatic
<br />pressure on structurai walls, This design allows the
<br />evaluation of the costs and beneflls of a structure that
<br />incorporates the wet flood proofing criteria developed for
<br />the Jersey Shore Disaster Urban Renewai Area redevel,
<br />opment projects'
<br />
<br />The other three designs were for building types flood
<br />proofed to meet the minimum requirements of the Na-
<br />tional Flood Insurance Program, Two designs were flood
<br />proofed to one foot above the base flood level (base
<br />flood ~ 551 above mean sea level (MSL)): one through
<br />raising on fill and the other through a combination of
<br />raising on fill and equipping with watertight closures, The
<br />structure raised on fill would be required to be only at,
<br />and not 1 foot above, the base flood elevation, However,
<br />in order to compare buildings susceptible to equivalent
<br />levels of flood inundation the structures on fill were de,
<br />signed to the same elevation as the fill-plus-closure
<br />structures (which must be flood proofed to 1 foot above
<br />the base flood in order to be insured at rates for the base
<br />flood elevation), A third design flood proofing soiution
<br />was raising the building on columns; in order that the
<br />space beneath the eievated building would be usable for
<br />parking and delivery, this design was raised one full
<br />story, to a height of 6 feet above the base flood level.
<br />The three flood proofed designs provide a basis for the
<br />comparative evaluation of various construction ap-'
<br />proaches that can be used to conform with flood insur-
<br />ance program flood proofing requirements,
<br />
<br />The major objectives in the design of the flood proofed
<br />structures were:
<br />1, to protect the structure and contents from damages
<br />due to the base flood and all fioods of iesser magnitude;
<br />and
<br />2, to reduce losses from fioods of greater magnitude
<br />(lesser frequency),
<br />
<br />All relevant national and local codes, ordinances, and
<br />statutes were observed in the design of all five building
<br />types, In addllion, the buildings were designed in accord,
<br />ance with the design goals established for the Jersey
<br />Shore Disaster Urban Renewal Area redevelopment in
<br />the urban renewal area. Particular attention was given to
<br />the following goals, which emphasize historic preserva-
<br />tion, compatibility with the borough's image, and the
<br />preservation and creation of open space:
<br />New development in the Jersey Shore Disaster Urban
<br />Renewal Area should have as an additional design goal
<br />the preservation of existing structures and areas having
<br />significant historical value and through the establish,
<br />ment of criteria for new construction to develop and main-
<br />tain a harmonious theme between old and new archi,
<br />tecture, If this were achieved, values of existing struc'
<br />tures would be enhanced, new construction would not
<br />become "dated" in a short period of time and the unity
<br />of theme would be esthetically pleasing, creating a
<br />more relaxed atmosphere for the shopper, worker or
<br />resident housed or employed in the area,
<br />
<br />Due to the limited amount of "green area" in the core
<br />area, it should be a design goal that eveI)' effort be
<br />made to preserve existing green Breas, flora and fauna,
<br />as well as establishing new open and green areas to
<br />provide sufficient light, ventilation and esthetic relief,
<br />Location of structures should be such as will create
<br />open areas, take best advantage of sun, shade and
<br />view and allow for future expansion where it is deemed
<br />probable, '
