I interrnret this as <br />pertaininn to adult education as requirenents for such usage is less severe <br />than for classrooms used for students in the elementary or secondary grades. <br />^V plan review, based upon your infora^ion and the plans aidimitted by k*r. <br />Hillepass, determines the following: <br />CP<1.The building is of ConstTUCtion Type V-N, rdiich by floor area and <br />location is allowable for your* intended usage. <br /><i<^c <br />( <br />>bS <br />(?»<4. <br />* » <br />A <br />* m - <br />4 > <br />X <br />I <br />» 'i <br />i •. t “■ <br />.i <br />t.
