Lane at 14.3' - higher readings south of stream) with USGS
/' S 33ro9 correction for lesser Zone - Zone D instead of Zone C.
1953C1 Highest groundwater therefore 14.3 + 1.5 = 15.13'. LEACHING FACILITY REQUIREMENTS:
Present design meets prior design criteria. Table 1 data DESIGN PERC. RATE 2 MIN./IN,
t column shows recently verified high groundwater at site with 330 G.P.D.

Is from April 1986 at 12.4 feet. U.S.G.S. high groundwater
• calculations for higher Zone (Zone C), is 3.4.Highest
groundwater used therefore 12.4 + 3.4 = 15.8'.
