Project Description
The applicant intends to demolish an existing
residence and requests Design Review approval to construct a new 4,688 square
foot single family residence with an attached 536 square foot garage and 936
square foot detached accessory structure on a lot in Mill Valley. The applicant
also requests Tree Removal Permit approved to remove one protected tree and one
heritage tree. It appears the proposed Building Area is 6,337 square feet and
it appears the proposed Floor Area is 5,624 square feet. The 5,624 square feet
of proposed development would result in a floor area ratio of 28 percent on the
20,048 square foot lot.
The proposed residence would reach a maximum
height of 29 feet 11 inches above surrounding grade and the exterior walls
would have the following setbacks: 26 feet 9 inches from the eastern front
property line; 10 feet from the southern side property line; 10 feet from the
northern side property line; and more than 50 feet from the western rear
property line.
The proposed detached accessory structure would

exterior walls would have the following setbacks: more than 50 feet from the eastern
front property line; 50 feet from the northern side property line; 21 feet from
the southern side property line; and 28 feet from the western rear property
line. Various site improvements would also be entailed in the proposed
development, including a pool, trash enclosure and landscaping.
