The proposed development would result in a building area of 6,977 square feet and a floor area of 6,520 square feet which would result in a floor area ratio of 23.8 percent on the 27,421 square-foot lot (the floor area ratio calculated per the Kentfield/Greenbrae Community Plan would be 25 percent). The proposed additions would reach a maximum height of 23 feet, 6 inches above surrounding grade and is proposed to be located 30 feet, 4 inches from the northern front property line; 38 feet, 6 inches from the eastern side property line; 31 feet from the western side property line; and 30 feet, 7 inches from the southern rear property line. Various site improvements include the construction of new exterior stairs along the southeasterly elevation of the house.
