(OCe) on behalf of the Fishers Island Ferry District (FIFD), herein submits the additional information as you requested for the above referenced CLOMR application. As you noted, the certified topographic survey elevations and contours were referenced to two (2) datums: mean low water (MLW) waterward of the One Year Frequency Tidal Flood, and National Geodetic Vertical Datum of 1929 (NGVD29) upland of the One Year Frequency Tidal Flood (a difference of 0.9 feet). Our original CLOMR submittal was based on our assumption that the entire site plan was referenced to ML W. As such, adjustments were made to our calculations to reflect upland elevations that are referenced to NGVD29. OCC has made appropriate corrections to the data and is resubmitting the items affected by this change. It should be noted that as a result of the adjustments to the elevations, the proposed AE Zone elevation is reduced from +12 feet to +11 feet. In addition, per your request, we have revised our offshore flood elevations (outboard of the proposed bulkhead) to reflect the highest elevation from our WHAFIS analysis rather than the average elevation from WHAFIS. We have also attached a revised certified bulkhead section from GNCB that includes information on the riprap toe protection and length oftlie tie-back as you requested. Please note that the structural engineering calculations previously submitted for the bulkhead were based on a ML W datum for both upland and offshore elevations and as such, no corrections to these calculations are required. Please fmd enclosed the following items that have been revised to reflect upland elevations referenced to NGVD: . Revised Elevation Information Form, MT-l Forms 2 & 5 .

The significant wave height and period were calculated using the Army Corps of Engineers Automated Coastal Engineering System (ACES) computer model for a restricted fetch analysis. The ratio of significant wave height to deep water wave length and the nearshore slope were entered into Figure 3-53 on page 3-109 SPM. The resulting ratio was multiplied by the significant wave height to determine the set-up due to random storm waves. Spreadsheets have been included for reference. 2) The revised analysis was performed using FEMA methods provided in "Guidelines and Specifications for Wave Elevation Determination and V Zone Mapping." The significant wave height analysis was performed using the restricted fetch analysis module in the Automated Coastal Engineering System (ACES) program. The revised analysis also takes into account the proposed bulkhead that will serve to protect the property from the wave damage characteristic of a V -Zone. Due to protection provided by this structure, our analysis shows that portions of the Fishers Island Ferry District Terminal property cannot support 3 foot breaking waves and therefore should be reclassified into. A-Zones.. 3b) The top elevation of the bulkhead is +9.0 feet NGVO and the 100 year storm still water elevation is at +10 feet. Therefore, the structure is submerged, and consequently overtopped before any wave action is considered. It is not applicable to perform a runup and overtopping analysis on submerged structures. 7) The coastal high hazard areas have both increased and decreased as a resuh of the revised analysis. The majority of the site is currently listed as VE Zone Elevation 12 and AE Zone Elevation 10. The revised analysis indicates that there will be a VE Zone Elevation 15 which will terminate at the proposed bulkhead followed by a 30 foot buffer zone of VB Zone Elevation 12. The remainder of the site will be AE Zone Elevation 11. 11) Changes in the location of the V -Zone and A-Zone and base flood boundaries are depicted on the revised workrnap.

I I I I I I I I I I I I I I I I I I I Fishers Island Ferry District Application for CLOMR Supplement #2 New London, CT August 21,2002 TEMPORARY WAVE BARRIER OPERATION PLAN REVISION Pwpose: The proposed top elevation of the bulkhead is +9.0 feet NVGD everywhere except in front of the ferry ramps. The top elevation of the bulkhead in these two 20 ft wide sections is +5' NGVD. This lower elevation is necessary due to the operational requirements for vehicles loading on/off the ferry. Temporary wave barriers have been designed to compensate for the lower bulkhead elevation in these locations as shown in detail on drawing # 202013-01. The top elevation of the barrier is +9.0 NGVD to coincide with the other sections of bulkhead. The wave barriers are not intended to stop the flow of water. However, they will trip the incoming waves in the same manner the original bulkhead will. The panels will be installed adjacent to the bulkhead. The panels have been designed to resist the forces associated with 100-year storm wave conditions. Description: The temporary wave barriers are constructed from sheet pile panels. The sheet piles will be the same as those used in the construction of the bulkhead. The sheet piles will be held together and supported by steel W section wales. H pile stanchions in pre-cast concrete sockets will be utilized to provide vertical support to the panels (see detail on drawing #202013-01). Ooeration: The Temporary Wave Barrier Operation Plan will be implemented when water levels in New London Harbor reach an elevation of +4.0' NGVD. A tide mark for elevation +4.0 NGVD shall be maintained on-site in a location that is apparent to Fishers Island Ferry District personnel. Forklifts are available on-site for installation of the panels. Remove the covers from the pre-cast concrete sockets. Insert the H-pile stanchions into the concrete sockets. Insta1I the wave panel with the wales inserted between the flanges of the H- pile stanchions. Personnel should be familiar with of the Temporary Wave Barrier Operation Plan and the use of the temporary wave barriers. Insta1Iation of the temporary wave barriers should be practiced on a quarterly basis. OCEAN AND COASTAL CONSULTANTS, INC.
