3) The DEP has specified that the 100 year storm elevation is 17.3 feet. This requires that the elevation of the bottom of the lowest horizontal member is required to be at 17.3 feet. The proposed top of the pile cap is proposed to be at 5.17 feet. Please revise the plan to meet the above requirement.
9/23/08 2nd submittal: For clarity please provide a cross section which depicts the total length of pile and grade beam up to and including the lowest horizontal member. Depict the top of pile cap elevation and the elevation of the bottom of the lowest horizontal member (Specify in NGVD).
The DEP also requires that no habitable space is allowed below tha 100 year storm elevation. This space is limited to parking, storage and access. The plans depict uses that aren't allowed such as utility room, mechanical room, rec room, foyer, future bath and future snack bar. Please revise and resubmit.
9/23/08 2nd submittal: Issue resolved on the revised architectural plans. This part signed-off.

4) All construction below the 100 year storm elevation shall be independent of supporting structural members that are intended to withstand wind forces but to collapse from the water load. In other words the walls need to be break away. Furthermore, slabs below the 100 year storm elevation are required to be non-structural and break away. In addition FEMA requires that all construction below the BFE ( defined at 14 feet NGVD) must be flood resistant materials. Please revise and resubmit.
9/23/08 2nd submittal: 1) The Sheet S1.1 shows the slab on grade floor plan. It is unclear that the walls between colums are breakaway. The Note specifies it as a CMU bearing wall instead of a breakaway wall. Please review, revise and resubmit.
2) The sheet S2.3 shows detail 10 depicting the breakaway wall. The column for this wall is specified as a CMU Pilaster. This is not consistent with the reference to detail 3/S2.3 or 4/S2.3 for the columns which are concrete not block. Please depict detail 10 to have a concrete pilaster.

8) The pile design ratio or pile spacing to pile diameter should not be less than 8:1 for individual piles located above the design grade. Some of the piles on the plan are not in compliance with this requirement. Please review, revise and resubmit.
9/23/08 2nd submittal: Some of the columns are placed closer than the 8:1 ratio. Please explain how the 8:1 ratio for piles does not apply to the columns above design grade.

11) The land development Code specifies that :" Electrical, heating, ventilation, plumbing, air conditioning equipment, and other service facilities shall be designed and located so as to prevent water from entering or accumulating within the components during conditions of flooding."
Obviously the main sanitary drainage must be below BFE therefore this would be allowed.
