Page #2
II. FINANCIAL IMPACT:
The estimated project cost is $397,000. funded by FEMA (75%) and
State (25%).
III. REASONS FOR RECOMMENDATION/BACKGROUND:
The project includes repairing bank erosion and slip-outs by excavating and
removing loose slope material and replacing it with rock slope protection and
repairing a headwall.
It is needed to minimize erosion of the creek banks and road shoulders.
The project has been determined to be in compliance with the General Plan and
is exempt from CEQA because it is an alteration to an existing facility with no
expansion of use.
IV. CONSEQUENCES OF NEGATIVE ACTION:
Delay in approving the project may result in further erosion.

GENERAL CONSIDERATIONS;
1, Location: Repairs will be made in several areas within the county (Figures 1-11).
2, Project Description: The project consists of repairing bank erosion and slip-outs by excavating
and removing loose slope material and replacing it with rock slope protection (Figure 12) and
repairing a headwall. Repairs will occur at the following sites:
Site Location Tvtaa of Repair
Franklin Canyon Rd. at Dutra Rd, (Fig. 2) Repair failed headwall
McHarry Ranch Rd, West of Franklin Cyn. (Fig. 3) Repair failed Rock Slope Protection (RSP)
Christie Rd, South of Hwy. 4 (Fig. 4) Repair failed bank with RSP
Rheem Crk. at 20th and 11th Streets (Fig. 5) Repair 2 bank erosion sites with RSP
Garrity Crk. at Shamrock Dr. (Fig. 6) Repair 4 bank erosion, 3 slip-out, and
2 undermined sites with concreted RSP
Rodeo Crk. at Viewpoint Blvd. (Fig.7) Repair 5 bank erosion sites with RSP
Grayson Crk, at Chilpancingo Pkwy. (Fig. 8) Repair bank erosion with RSP
DA 128 Line A at Smith Lane (Fig. 9) Repair bank erosion with RSP
San Ramon Crk. at Stone Valley Rd. (Fig. 10) Repair 2 bank erosion sites with RSP
and replace broken concrete apron
Pacheco Crk. at Arthur Road (f=ig. 11) Repair bank erosion with RSP
If flawing water exists in the creeks it will be necessary to divert water around sites to perform
work. Therefore, best management practices such as cofferdams, pilot channels, pumping, and
silt fences will be used to prevent construction generated materials from entering the water, All
loose rock slope protection will be covered with soil above the ordinary high water mark. All bare
slopes will be seeded with native grasses. One approximately.8" dbh non-native tree will be
removed at the Franklin Canyon/Dutra Road location, however, it is located in a heavily vegetated
area and is not considered a scenic resource.
