The roof design allows for the collection and control of all preapitation falling on <br />the structure. Heated roof drains collect water and direct it into dispersion tanks. <br />Over 4000 gallons of runoff can be held within the tanks (the equivalent of 2" of <br />ram falling in one hour). The runoff is then dispersed and absorbed by the soil in <br />a manor similar to a septic field Only the runoff from the walk, drive and <br />landscape borc'er would need to be shed onto the surface of the surrounding <br />landscape. This area would only be 12% of the 75’ to 250' zone. <br />Alternatively it would be quite simple to control alt of the runoff on the drive by <br />using a curb’, sloping the dnve to a large grate drain, and then directing the <br />water into our dispersion tanks and controlled runoff field. This method would <br />reduce uncontrolled runoff by 5.4%. This reduction alone would bring the <br />hardcover percentage down from 29 2% to 23.8% in the 75* to 250* zone. <br />The site will be left in its existing heavily vegetated condition where possible. <br />Note that 292 sq. ft. of hardcover is due to a 2’ wide protective landscape <br />border. This Border can be omitted, but our experience shows that this border <br />significantly helps direct water away from the foundation. <br />Additional Finding <br />Orono currently has a 60* street right-a-way on Forest Lake Landing, but only r^uires <br />50*. If 5' were vacated on each side and deeded back to the property owners, this wou d <br />increase the 75’ to 250* zone by 740 sq. ft <br />Please note that a small portion of the house does not comply with the 30’ height <br />restriction. The upper level of the rotunda protrudes up teyond the adjacent complying <br />roofs in order to capture light which then filters down to light the levels below. (See <br />section) <br />We ask that a height variance be granted for this limited condition. <br />Sincerely. <br />Blake Bichanich <br />BB/hks
