CONDITIONS OF APPROVAL FOR;REZONING #2614-RZ:
1. As part of the permitting process for development of each lot, a geotechnical,
grading, and foundation design report shall be prepared. Such reports should assess
potentiaLland slide, slump, erosion, thin soil and expansive soil problems. Test borings
and trenches will be necessary.
2. Planning and engineering for all homesites, roads, and sewer lines shall consider
intense ground shaking and possible fault rupture. Additional studies shall be
conducted to further evaluate the seismic hazard. If the fault trace is located, all
single-family dwellings shall be set back 50 feet from the trace.
3. Grading shall be conducted during the drier months from mid-April through mid-Oc-
tober and shall be subject to review and approval of the Grading Engineer and the

are implemented.

during the rainy season would aid in removing debris and chemicals from the site will
be required.

worsened by excessive water use or leaks on the lots.
10. At least twice a year, Jones Ranch Creek shall be cleaned of all debris, preferably
before the rainy season and once during the rainy season. However, care must be
taken not to disturb the ecology of the stream area. Responsibility for clearing the
creek must be determined during the planning process.
11. The roads and driveways extending across or adjacent to the creek shall be designed
to avoid damage to the streambanks or stream channel. As an added protection to

f Page 2
homeowners, buildings adjacent to the streambank shall be designed for possible
creek flooding and set back at least 50 feet from top of bank.
r ..
12. Low lying lots shall have test borings made during the rainy season, to determine the
depth to groundwater for foundation design.
