CEQA Status: Article 19. Categorically Exempt per Section: 15303 - New Construction or

Summary:
The applicant, Joyce Ford, is requesting a hillside area construction permit and a front setback
variance for a first and second floor addition qualifying as new construction at 2930 Adeline
Drive, zoned R-1. This residence is within the area designated as the hillside area by Ordinance
1448 which requires a hillside area construction permit for any addition to all or a portion of an
existing residence. This site is located adjacent to Mills Canyon Park. The project qualifies as
new construction, therefore a front setback variance is required for 44'-0" (measured to the first
and second floors), where 49'-8" (average of block) is required. Present frst floor front setback
is 44'-0". The proposed new second floor front setback matches the first floor at 44'-0".
The applicant is proposing to add an entry and dining room on the iirst floor (134 SF) and expand
an uncovered deck (631 SF). The applicant will be removing the front covered porch (209 SF)
to add the entry and dining room. Lot coverage would be increased to 3,671 SF (7%), which
includes uncovered decks, exterior stairways and balconies which exceed 30" in height above
adjacent grade. The applicant is also proposing a 2,939 SF second floor addition, bringing the
total floor area of tt�e house to 5,755 SF (.11 FAR) (including the garage and open spaces 12' or
higher and exempting 100 SF of covered porches, CS 25.08.265). The maacimum allowable house
size is 8,000 SF (.16 FAR). The areas under the second floor balconies are considered covered
porches since they are over an exterior exit from the dwelling (CS 25.08.265, 2). The proposed
second story addition matches the footprint of the first floor. The second story addition would
provide two uncovered balconies (280 SF), three bedrooms, two and one-half bathrooms, an office
Hillside Area Construction Perneil & Front Setback [�arrance 2930 Adeline Drive
room and a family room (2,708 SF). A second exit is required on the second floor for any
dwelling exceeding 3,000 SF in gross floor living area. The applicant is providing a second exit
from the family room on the second floor by way of an exterior stairway. The lot slopes 165'
(39 %) downward along the left side property line, 161' (33 %) downward along the right side
properly line, and has a cross slope of 14' (23 %) from left to right along the front property line.
Because of the slope the top of the second story addition will be a ma�cimum of 4'-3" above the
paving edge along Adeline Drive.
The existing two bedroom, one and one-half bathroom house is 2,586 SF (.OS FAR) (including
the front covered porch and attached garage). The existing house also contains a 632 SF first
floor uncovered deck. This project qualifies as New Construction (addition is 95% of the existing
gross floor area) and Floor Area Ratio applies. Any single family dwelling qualifying as New
Construction must provide off-street parking for at least three vehicles, two of which must be
covered. The e�cisting attached garage has a 25'-6" wide X 21'-6" deep clear interior dimension
which meets the parking requirement. All other zoning code requirements have been met.
The project was called up for review after neighbors within 100' of the property, Planning
Commission and City Council were noticed. Several neighbors expressed their concerns in a
letter dated February 10, 1998. Their concerns include possible obstruction of long distant views,
construction hours and noise and traffic congestion due to construction.
