RUN TOPO PERFORMED ON 5/27/2022 USING RTK GPS RECEIVERS AND/OR A o 4733 -
ROBOTIC TOTAL STATION. THE SURVEY DID NOT COLLECT ELEVATION DATA BEYOND
THE CREEK TOP OF BANK. IN GENERAL, THE SURVEYED TOP OF BANK ELEVATIONS CROSS SECTION "F"
ARE ABOVE THE CORRESPONDING BASE FLOOD ELEVATION, AND THEREFORE THE
FLOODPLAIN BOUNDARY(BASED ON TOPOGRAPHIC SURVEY DATA) WOULD BFE = 4733.E
GENERALLY NOT EXTEND OUTSIDE THE TOP OF BANK. THE SURVEYED TOP OF „ STREAM DISTANCE/STATION 2,032
BANK ELEVATIONS ARE NOTED ON THIS EXHIBIT. IN A FEW LOCATIONS (NEAR THE PER 2021 FIS SHAPEFILES
SOUTHEAST CORNER OF THE PROPERTY AND JUST NORTH OF THE NORTHERN
PROPERTY BOUNDARY) THE BASE FLOOD ELEVATION IS ABOVE THE SURVEYED TOP "
OF BANK. IN THESE LOCATIONS, THE FLOODPLAIN DELINEATION IS SHOWN BASED
ON WHERE THE BASE FLOOD ELEVATION INTERSECTS NATURAL GROUND. FOR
AREAS WHERE THE BASE FLOOD ELEVATION IS BELOW THE SURVEYED TOP OF "•ai
BANK, THE FLOODPLAIN BOUNDARY IS CONSERVATIVELY ASSUMED TO FOLLOW TOP -
