No. The County Surveyor only performs on County owned land, including County road and flood control channel rights-of-way.
Only a land surveyor or qualified pre-1982 civil engineer licensed in the state of California can provide property line location for a private survey in this state. Contact information for these professionals can be found in a telephone directory, by searching the Internet, or by contacting engineering and land surveying societies (see Resources, P. 22 of the Consumer Guide to Professional Engineers and Professional Land Surveyors or California Land Surveyors Association, Find a Surveyor). The California State Board website is another source of information for researching licensed engineers or land surveyors in your city or county where you can verify that the professional is currently and properly licensed and find out if there have been any complaints or disciplinary actions taken against the person’s license.
When interviewing land surveyors ask for local references on similar projects and compare qualifications and experience. Also, ask if they have previous experience working with your local planning department, public works department, municipal utility district, or County Surveyor’s Office. For your protection, the State Board insists that a formal contract is made between professional and client.

The Flood Control District has over 2,000 data points where the flow rates have been calculated. Most of these are the “design” flow rates based on General Plan build out2. Depending on the watershed size, the flow rate could be for the 10-year, 25-year, 50-year or 100-year flood. For information on the flow rates that the Flood Control District has for these data points call theCounty Public Works Department, Flood Control Division at (925) 313-2000 or email your request.
For tract numbers for the entire county, and parcel map numbers for the unincorporated areas of Contra Costa, contact the Department of Conservation and Development (DCD) (925) 674-7722. For parcel maps in other cities, obtain the number from the city.
The Flood Control District does not provide sand bags to private property owners. Often, in times of emergencies, the County may provide sandbags during significant storm events to residents in the unincorporated county.
There are, however, locations throughout the County where residents may go to fill their own sandbags. Please note that you will need to bring a shovel, but the bags and sand are available for free. For more information on this, please visit the County's webpage for sandbag locations.
If you live in a City, contact your City Public Works Department for information and/or assistance in preparation for conditions requiring their use.
