PRE 03-01 - THOMPSON/TABATA - AFFORDABLE HOUSING SITE PLAN
Standard Pacific Homes recently processed a consistency determination for some
revisions to the single family home architecture. They have just requested a change to
the proposed affordable housing site plan, more specifically a relocation of the trash
enclosure area to the existing Fire Department turn-around area.
Attached are the approved plans and the proposed revisions from Standard Pacific for
your review. Thank you for any comments you can provide. Please feel free to contact
me at x4623 if you have any questions.

C. STANDARD FOR ACCESS
1. COMMON
a. Single- and Two-Family Residence

Driveways shall be maintained a minimum clear width of 20 feet with
'FIRE LANE" signs posted at 50 foot intervals (see Pages 9-11).
Where parallel parking is allowed on one side, an additional 8 feet in
the minimum driveway width shall be required, giving a total of 28 feet
in width.
Where parallel parking is allowed on both sides, an additional 16 feet in

road/driveway designs shall be 450 feet.
Cul-de-sac turnarounds, intermediate, and "T" turnarounds shall
have a minimum 34-foot centerline turning radius with 20 feet clear
