1.TOPOGRAPHIC CONTOUR INTERVAL = 2 FEET.
2.GROUNDWATER SURFACE CONTOUR INTERVAL = 10 FEET.
3.GROUNDWATER ELEVATIONS MEASURED ON JANUARY 17, 2017.
4.GROUNDWATER CONTOURS ARE BASED ON LINEAR INTERPOLATION BETWEEN AND
EXTRAPOLATION FROM KNOWN DATA, TOPOGRAPHIC CONTOURS, AND KNOWN FIELD CONDITIONS.
THEREFORE, GROUNDWATER CONTOURS MAY NOT REFLECT ACTUAL GROUNDWATER
CONDITIONS.
5.GROUNDWATER CONTOUR LINES SHOW THE WATER TABLE SHAPE AND ELEVATION. THESE
CONTOURS ARE INFERRED LINES FOLLOWING THE GROUNDWATER SURFACE AT A CONSTANT
ELEVATION ABOVE SEA LEVEL. THE GROUNDWATER FLOW DIRECTION IS GENERALLY
PERPENDICULAR TO THE GROUNDWATER SURFACE CONTOURS, SIMILAR TO THE RELATIONSHIP
BETWEEN SURFACE WATER FLOW AND TOPOGRAPHIC CONTOURS.
6.SURFACE WATER MONITORING POINT SW-1 IS APPROXIMATELY 550 FEET OFF THE MAPPING LIMITS
SHOWN AND IS COLLECTED FROM SECOND CREEK.
7.MONITORING WELL MW-27A IS UTILIZED FOR WATER LEVEL MONITORING ONLY.
8.THE LOCATION OF THE FRENCH DRAIN MONITORING POINT IS APPROXIMATE.
