Survey's Frequently Asked
What are the Survey Counter Hours?

•How can I tell where my property lines are?
Refer to the current deed, available from the County Recorder, for a description of the
property. If you're lucky, the description will refer to a recorded map. The
existence of such a map of or even near your property increases the likelihood that survey
markers (or "monuments") were set and may still be in place to help you locate
your property corners. In any event, a visit to our office (in Public Works) can
establish what, if any, maps exist. An index of
recorded maps is now also available on the internet at
It may also be useful to ask your neighbors if
they have located their own corners recently for a building permit or other reason.
When all is said and done, if it becomes necessary for you to hire a private surveyor to
locate your property lines, any research you do yourself will generally save time and
- Will the County survey my property?
No. County employees cannot undertake private survey work within their
jurisdiction. The conducting of private surveys by
the County’s survey crew would constitute unfair
and illegal competition with private surveyors doing work in the
county. Refer to the yellow pages under "Surveyors - Land" should you need
private survey work performed.
- My neighbor's property was surveyed. Why isn't
there a recorded map?
State law requires that a map be recorded when a surveyor sets a permanent marker
with the surveyor's registration number attached. There are several instances where
a survey might be performed without the setting of permanent markers (without
"monumentation," as it were), including the following.
- Sufficient existing monumentation was found, eliminating the need to set new permanent
- The surveyors client commissioned the survey for informational purposes only, so
only temporary markers, such as lath and ribbon, were set.
- The survey was of a type other than a boundary survey, such as a topographic or a
planimetric survey, often done to detail existing ground, landscape, and structures for
a proposed development.
- The survey was not completed (and, presumably, no monuments were set), because the
project was abandoned or the surveyor was not paid.
- Do all properties in the county have a recorded map?
No. A great many of the parcels of land existing in the county were created
before legislation was enacted in 1972 requiring a subdivision final map or a parcel map
to create new parcels. A deed, therefore, may be the only recorded document
describing the boundaries of a longstanding parcel. Please note that a formal survey
of an existing parcel is not normally a County prerequisite to the issuance of a building
- Is a recorded survey map the absolutely correct and
final word on my property line, sanctioned by the County?
No. All recorded maps (subdivision final maps, parcel maps, records of survey,
etc.) are based upon an historical record which over years has collected many
discrepancies, conflicts, and uncertainties. The surveyor can only identify
pertinent inconsistencies and apply informed judgment in assembling maps based on research
and fieldwork. The County Surveyor reviews maps submitted for recording according to
standards of practice and technical requirements, but does not adjudicate inconsistencies
in the historical record. Disputes over property lines may have to be resolved as
civil matters before judicial courts.
- Is it illegal to pull out survey markers?
Yes. Under Section 605 of the California Penal Code it is a misdemeanor to
intentionally remove or destroy a permanent survey marker. Removal or destruction of
survey markers should be reported to the County Sheriff's office, or to the appropriate
police department if it was done within one of the four incorporated cities. If the
monument is removed by a professional land surveyor or civil engineer, you may also file a
complaint with the State of California Board of Registration for Professional Engineers
and Land Surveyors at (916) 263-2251, or at the Board's website, http://www.dca.ca.gov/pels/l_enforce.htm.
Survey markers are sometimes destroyed during major construction projects if it is
impossible to protect them in place because of the nature of the work. If this
occurs, the obliterated markers should be replaced or memorialized in another way that
will maintain continuity of the historical record.
- What is a permanent survey marker?
Typically, a surveyor will hammer a 1/2-inch diameter or larger iron pipe to ground
level (or even below ground level to protect the pipe, necessitating a metal detector to
locate it). The pipe will generally be 2-1/2 feet long with a brass or plastic tag
containing the surveyor or engineer's registration number on top. In concrete there
may be a lead plug with a tag instead of a pipe. Significant locations in roadways,
bridges, etc., may have more elaborate and stable monuments. Wooden stakes or lath
with ribbon, or nails in asphalt with paint marks are not considered permanent markers.
- My land division project was approved and I just got my
development permit. What do I do now?
The process of dividing and developing land calls for
a significant investment of time and money. Congratulations are in order for anyone
who sticks it out to get a tentative land division map approved by the Planning Commission
and becomes the holder of a land division and development permit. The next stages of
the process, where one fulfills the requirements of the permit, can be just as
rigorous. In order to record a final map or parcel map, the conditions in the
permit, so-called "tentative map conditions," must be fulfilled. Look at
the permit under the heading "Prior to or concurrent with
recordation of the final/parcel map, the following conditions shall be met."
The following is typical of what it takes to get a final or parcel map recorded once
the Planning Department issues a development permit which includes a land division.
The permit typically allows you two years to do this.
1. Submit final engineered improvement plans to the Surveyor and Development Review
section of Public Works, together with any pertinent supporting information, such as
drainage calculations, structural calculations and soils reports for retaining walls, and
a preliminary engineers estimate of the cost of construction.
2. Submit a final or parcel map to the Surveyor and Development Review section of
Public Works, together with any pertinent supporting information, such as closure
calculations, preliminary title report, and pertinent deeds.
3. Submit the soils report and an erosion control plan to the Environmental Planning
section of the Planning Department.
4. Submit copies of the improvement plans to the appropriate water purveyor for review
and comment. In addition to Public Works approval, the plans will have to be
approved by the water purveyor. Furthermore, if the improvements include a water
main extension, youll probably have to enter into a main extension agreement with
the water purveyor and submit whatever securities and fees the water purveyor requires.
5. Submit a landscape plan and a biotic restoration plan, if required, to the
Environmental Planning section of the Planning Department.
6. Submit any landscape, biotic, drainage, roadway, sanitation, or other maintenance
agreements, homeowners agreements, and conditions, covenants and restrictions
(CC&Rs) to Public Works and Planning.
7. Acquire any easements and rights-of-way necessary to construct required improvements
or gain access or secondary access to the project.
8. In the case of full tract subdivisions (five or more lots created), enter into an
agreement countersigned by the Planning Director to
meet the County's affordable housing
9. Execute a subdivision agreement with Public Works, agreeing to make the
improvements shown on the plans and required by the tentative map.
10. Submit construction securities in the form of a letter of credit from a financial
institution or a cash instrument to insure construction of the required
improvements. The securities will be based on the estimate of the cost of
construction, the cost of deferred monumentation in the case of tracts, and the amount
required to secure the coming years taxes on the property underlying the
subdivision. In addition, all property taxes
currently due must be paid in full. Typically, the overall amount of securities is a bit more than 150% of
the estimated cost of construction.
11. Pay all fees due prior to recording. Typically, these include drainage fees,
road and roadside improvement fees, park dedication fees, child care fees, additional
review fees, pavement striping deposit, and construction inspection deposit.
12. In the case of tracts, the project must be placed on the Board of Supervisors'
agenda to get the final map approved. It takes about three weeks lead time to do so.
