FETCH LENGTH 



0.0 to 1.0 mile (1.6 kilometers) 

 1.1 to 5.0 miles (8.0 kilometers) 

 5.1 to 10.0 miles (16.0 kilometers) 



SOIL PROPERTIES 



Mostly cohesive (silts and clays) 

 Mostly granular (sand) 



Tidal elevations and tidal range can be estimated if detailed surveys 

 are not available. To estimate tidal elevations, consult local tide 

 tables and make site observations during low water and high water periods. 

 Make these observations during calm periods when waves are low and there 

 are no local storm fronts. Use reference stakes to delineate the tidal 

 zone (MLW and MHW) . Consider the midpoint between the high and low 

 stakes to be MTL. Tidal range is the vertical difference between high 

 and low water. Tide tables can be obtained from private distributors 

 such as sporting goods stores, marinas, and fishing concessions, and from 

 the U.S. Coast Guard and U.S. Geological Survey. 



If specific information is not available, salinity can be estimated 

 using the following general guidelines. Water begins to taste salty at 

 about 3 parts per thousand. Seawater contains about 33 parts per thousand 

 salt. In general, the waters of bays, sounds, and estuaries will have 

 salinities lower than seawater because of the influence of freshwater. 

 Salinity will be less than 20 parts per thousand in waters which are close 

 to tributaries or are far from openings to the ocean. Salinity is likely 

 to be more than 20 parts per thousand near bay mouths and inlet openings. 

 Salinities greater than 40 parts per thousand are likely to be encountered 

 only in areas where circulation is poor, evaporation rate is high, rainfall 

 is low, and temperatures are high. Additional information on local salin- 

 ity regimes is often available from State departments of natural resources, 

 academic institutions, and the National Oceanic and Atmospheric Adminis- 

 tration (NOAA) . 



Fetoh length is the horizontal distance over which winds may blow 

 across open water to create waves. Consider only the longest fetches. 



STEP TWO : Turn to the planting decision key (Fig. 1 if site is located 

 on the Atlantic or gulf coasts; Fig. 2 if on the Pacific coast). Using 

 the appropriate planting decision key and the site description compiled 

 in STEP ONE, begin at the top of the key and move downward following the 

 appropriate path. The path will terminate in a block which either desig- 

 nates suitable plant species and planting methods or indicates the site 

 is not appropriate for planting. Information on obtaining plant materials 

 is in Appendix A; a description of each planting method is given in 

 Appendix B; and maintenance requirements are discussed in Appendix C.
