RECOMMENDED ACTION (continued):
AUTHORIZE the Public Works Director to arrange for payment of a $25 fee to Community
Development for processing, and a $25 fee to the County Clerk for filing the Notice of
Exemption.
II. FINANCIAL IMPACT:
The estimated project cost is $110,000.00, funded by AOB (100%).
III. REASONS FOR RECOMMENDATION/BACKGROUND:
The area was realigned in 1999, but during construction, additional areas were identified for
remediation. The contractor onsite was unable to complete the additional work prior to the end
of the contract. The purpose of this project is to provide additional sight distance for the public,
regrade existing slopes to provide adequate grades, and diminish drop-offs outside the edge of
pavement.
The proposed project consists of grading approximately 150 cubic yards of the slope and
constructing a modular block wall, approximately 260 feet long on the west side of Camino
Tassajara across from (west of) Bruce Drive. Two hundred of the 260-foot wide wall is
between three and six feet in height. On the east side of Camino Tassajara, approximately 300
feet south of Bruce Drive, placing an 16-inch culvert approximately 120 feet long in the existing
roadside ditch and grading the shoulder slope over it. Also, on the east side of Camino
Tassajara starting at Penny Lane, installing approximately 500 feet of 24-inch pipe in the
existing roadside ditch and grading the shoulder over it. Both drainage ditches were
constructed in uplands and neither support wetland vegetation. All graded materials will be
used to fill over the top of the new pipes.
The existing slope is very steep, unvegetated, and erodes into the roadway during winter
storms. The slope restricts site distance and needs to be modified. Re-grading the slope
(approximately 200 feet) on the west side of Camino Tassajara, approximately across from
Johnston Road will provide better positive drainage and sight distance. The wall is vertically
stair-stepped and will be attractive in appearance. The General Plan states that one should
consider the visual qualities of an improvement along a scenic corridor. The construction of
the retaining wall does not violate this policy. The visual quality of the retaining wall was
considered and the modular wall was chosen in part because of its aesthetically pleasing
appearance. The modular block comes in a variety of colors and the construction contract will
specify neutral tones that match the existing natural features.
SUBJECT: APPROVE the Camino Tassajara Realignment, Phase 2 Project and DETERMINE that
the project is a CEQA Class 1c Categorical Exemption. Project No. 0662-6R4169-00.

RECOMMENDED ACTION (continued):
Furthermore, the creation of the wall complies with several other goals and policies of the
General Plan, including:
➢ 5-A: Existing circulation facilities shall be minimized by eliminating structural and design
deficiencies.
➢ 5-9: Existing circulation facilities shall be improved and maintained by eliminating structural
and geometric design deficiencies.
> 5-13: Physical conflicts between vehicles and bicyclists, and pedestrians shall be
minimized.
➢ 5-30: Roads developed in hilly areas shall minimize disturbance of slope and natural
features.
The project has been determined to be in compliance with the General Plan and is exempt
from CEQA because it can be seen with certainty that there is no possibility that the activity
may have a significant adverse effect on the environment. The proposed project consists of the
maintenance and minor alteration of existing facilities involving negligible or no expansion of
use beyond that existing. The project will not result in the removal of any scenic resource.
IV. CONSEQUENCES OF NEGATIVE ACTION:
Delay in approving the project will result in a delay of design and construction and may
jeopardize funding.

GENERAL CONSIDERATIONS:
1. Location:
Along Camino Tassajara, between Bruce Drive and Johnston Road in the south county area,
near the Town of Danville and the City of San Ramon. (Figures 1-5)
2. Project Description:
The area was realigned in 1999, but during construction, additional areas were identified for
remediation. The contractor onsite was unable to complete the additional work prior to the end
of the contract. The purpose of this project is to provide additional sight distance for the public,
regrade existing slopes to provide adequate grades, and diminish drop-offs outside the edge
of pavement.
The proposed project consists of grading approximately 150 cubic yards of the slope and
constructing a modular block wall, approximately 280 feet long on the west side of Camino
Tassajara across from (west of) Brace Drive.Two hundred of the 280-foot wide wail is between
three and six feet in height. On the east side of Camino Tassajara, approximately 300 feet
south of Bruce Drive, placing an 18-inch culvert approximately 120 feet long in the existing
roadside ditch and grading the shoulder slope over it. Also, on the east side of Camino
Tassajara starting at Penny Lane, installing approximately 500 feet of 24-inch pipe in the
existing roadside ditch and grading the shoulder over it. Both drainage ditches were
constructed in uplands and neither support wetland vegetation. All graded materials will be
used to fill over the top of the new pipes.
The existing slope is very steep, unvegetated, and erodes into the roadway during winter
storms. The slope restricts site distance and needs to be modified. Re-grading the slope
