On the <br />other hand, a 3" x 3" Fluted Post with a post height of 10'. 7" can support an area of 128 square feet of <br />area. Thus, design must satisfy both height and area requirements. <br /> <br />Lawrence E. Semett, P.E. <br />ow.. I!MIIlMt . ORII.CI'IIM' cc>>&I. TANr <br />P.o. BOX ..... lIOUnf DAYTONA.
