BEACH PROFILE DATA SHEET
TOWN/BEACH: Marshfield/Rexhame Town Beach PAGE: 1 OF 5 Transect # RB2 Date: 8/30/99 Name: Jim O'Connell
Top elevation of permanent monument (optional): 14.4 feet NGVD Sand surface from top of permanent monument: 13.4 feet NGVD Top elevation of profile stake (optional): 29.2 feet NGVD Sand surface elevation at profile stake: 28.29 feet NGVD Geographic coordinates: permanent monument: Geographic coordinates: profile stake: N42o-7'-22.5"/W70o-40'-41.3" Transect compass bearing: N89E
Distance from Permanent Monument in Feet
Rod Reading in feet and tenths of Feet
Cumulative Elevation - add previous rod reading
Remarks: I surveyed the top of my permanent monument at 14.4 NGVD. The sand surface was 12 inches down from the top of the monumnet. Thus, I began my profile at 13.4 feet NGVD (see Figure D).

NOTES: The highest point of the dune ('dune crest') is at 29.84 NGVD. The top is above the 100-year flood elevation. Therefore, my dune may prevent storm wave overtopping and thus some degree of flood protection to landward areas (see Figure D).
