TO CONTRA COSTA BOARD OF SUPERVISORS
FROM MARIA LAWRENCE Tel. 925.820.3400 fax 925.820.3570
This is the second time I come before you to speak. I am asking for improvements to be made to a
section of Green Valley Road, approximately 1700 feet. This section does not conform to the
conditions of approval for development of this road. NO IMPROVEMENTS were made in this
section.
This section of Green Valley Road has a creek running parallel to the road.. The creek bed is
approximately 30 feet lower than the road. The shoulder width varies with a narrow section of
about 3 feet behind the guardrail, and a sharp drop to the creek bed. This is a"woodsy"area with
many oak trees that are 200-300 years old. Two lots, 501 and 502 have not yet been developed.
These lots are on a hill that is approximately at a 65 degree angle to Careen Valley Road. Opposite
these lots there is a section where massive amounts of dirt has eroded and the white street stripe is
14 feet from a drop of approximately 30 feet.
ISSUES -PUBLIC SAFETY,FIRE,EROSION
Pedestrians walking behind the guardrail for safety, on the edge of a 30 foot drop to the creek
Fire 12130199 response# 099006497.
Massive erosion has already occurred.
FACTS
1. #8 Hardsurfaced pedestrian path shall be provided from No 1881 Green Valley Road to
connect to the new sidewalk at lot 290.
2. #5 From 1935 Green Valley Road---road shall be widened to 28 feet with dykes in 60 foot
right of way..
3. #15 Sidewalks shall be constructed on all public streets.
4. The county has cut vegetation along the shoulder of the road. This has accelerated erosion and
exposed the roots of oak trees that are 200-300 years old.
5. The white street line on east side is 14 feet from a drop of approximately 30 feet to the creek.
6. Green.Valley road has a 5.5 traffic index as compared to Stone Valley Road which has 5.0
traffic index(rated by the county).
CONCLUSION
Improvements must be made along this section to conform to the conditions of approval for
development of this area. Specifically sidewalk on west side, street lights, and curbs. A barrier
must be place on the east side of the road to prevent fires, slow the erosion and save oak trees that
are approximately 300 years old. Concrete dykes must be place to support the road.
