Re: PRIVACY SCREENING ARBORIST ASSESSMENT
On April 13th, 2018, I visited 22998 Standing Oak Court, to assess the existing privacy screening
around the property and make recommendations for additional plantings if needed. The areas
assessed were the back and sides of the property (for viewing angle specifics, see attached plan
supplied by designer). I observed a mature row of coast redwoods (Sequoia sempervirens) planted
no further than 20 feet apart along the western property line. Mixed evergreen trees and shrubs
bordered the back fence and screened the existing deck and eastern property line. Species included
typical plants used for screening, including Pittosporum eugeniodes, Toyon (Heteromeles
arbutifolia), Privet (Ligustrum), Photinia, and Holly Oak (Quercus ilex). These evergreen trees
and shrubs were spaced to provide a screening affect, conforming to maximum spacing
requirements for their species as listed in Cupertino document "Privacy Screening Materials." In
cases where the specific species was not listed, spacing requirements were met for trees or shrubs
of comparable size and growth rate.
Based on my observations, I concluded that as defined by Cupertino City Code Chapter
19.28.070D, adequate privacy screening was being provided by existing trees and shrubs.
However, there was a 22 -foot -long space along the back fence where the screening was being
provided by the neighbor's trees. In this location, I recommended planting two (2) Arbutus
`Marina' at 11 -foot spacing (see attached plan), to provide redundancy on the Butala's side of the
fence.
If you have questions regarding this assessment, please do not hesitate to contact me.
