'Determined as total surface area of the segment from adjacent shoreline out to the 0.5-meter depth 
contour at mean low water minus any delineated SAV no-grow zone within the segment. 
Calculated as the shallow-water habitat area divided by 2.5 (the water clarity acres multiplier) (see 
U.S. EPA 2003a).

SAV restoration goal acreage could be calculated. 
vegetated bottom habitat. Based on the decades long record of published documen¬ 
tation on SAV light requirements (Batiuk et al. 1992, 2000; Dennison et al 1993; 
Kemp et al. 2001; U.S. EPA 2003a, 2004a), the EPA recommends that an attainment 
determination based on water clarity acres be based on 2.5 times each acre needed 
to meet the restoration goal acreage. 
A water clarity acre is defined as an acre of shallow-water bay grass designated-use 
bottom habitat, located anywhere between the 2-meter depth contour and the adja¬ 
cent shoreline inclusively, which has been observed to achieve the applicable 
salinity-regime-specific water clarity criteria. A water clarity acre cannot be defined 
within a delineated SAV no-grow zone (see pages 41-55 in U.S. EPA 2004c for 
narrative descriptions and maps of those zones). For segments in which the resultant 
water clarity acreage exceeds the total acres of shallow-water habitat from the 
shoreline out to the 2-meter depth contour, the water clarity restoration acreage will 
be set at the total acreage out to the 2-meter depth contour. 
Assessment of attaining a segment’s water clarity restoration acreage should be 
based on calculation of the arithmetic mean of the year-by-year arithmetic means of 
a month-by-month accounting of water clarity acres over the three-year SAV 
growing season assessment period. Calculation of water clarity acres should be
