Document Description
An oak tree permit request to authorize the retroactive encroachment into the protected zone of 16 oak trees for previously performed expansions on a property with a single-family residence. Twenty-five Coast Live Oaks (Quercus agrifolia) have been identified within the project vicinity. Oak tree numbers 1 and 3-18 have been impacted. Regional Planning previously approved the conversion of a guest house and garage into a single-family residence on August 30, 1994. Building permits from 1994 approved the addition of a walkway and decks which were not reviewed by Regional Planning. These additions encroached into the oak tree protected zones of trees 12, 13, 14, 15, 16, and 18. The property has since been paved which has modified the drainage of the site, causing a wash to the south of the property to erode, impacting trees 11, 12, and 14. The applicant has attained a Streambed Alteration Agreement (#1600-2003-5055-R5) from the California Department of Fish and Game in order to line the channel with concrete, which affected oak tree numbers 3, 4, 5, 6, 7, 8, 9, and 10. The applicant has also filed a plot plan for the retroactive approval to enclose decks and stairways and to construct a new carport for two tandem parking spaces.
