From the Editor Office of the County Surveyor n this issue of the California Surveyor we focus on California's county surveyors. The office of the county surveyor can provide a wealth of information for the professional land surveyor and today much of that information can be accessed through the internet. We hope you find our county surveyor website articles useful tools for your on-line research. There are 58 counties in the state and in this issue we only had space for a handful of articles. Drop us a line and let us know if you would like to see more counties featured in a future issue of the magazine. The following essay is but a brief overview intended for general interest reading only. Consult the appropriate statutes for complete and definitive information regarding the topics presented herein.
History of the County Surveyor The duties of the county surveyor were set forth in the first statutes of California, i.e., the statutes passed during the first session of the legislature, which began in December 1849 and ended in April 1850. I found it interesting that the office of the county surveyor predates California's date of statehood, September 9, 1850. The statutes created 27 counties, out of which today’s 58 have been carved. The last county formed was Imperial in 1907 from a division of San Diego. The first county surveyors were elected officers who were required to subscribe to an oath or affirmation to support the Constitution of the United States and the Constitution of the State of California. (Over the years most county surveyors came to be appointed by the county Board of Supervisors and today the last elected county surveyor is in El Dorado County.) The responsibility for surveying and mapping county boundaries actually belonged to the surveyor general, but he was authorized to delegate this task and many others to the county surveyor. There will be more on the relationship between the surveyor general and the county surveyor shortly. Among other duties, the first county surveyors were authorized to survey private lands divided by county boundaries. (This is still the case today.) I was surprised to learn that in those days only surveys executed by the county surveyor were considered legal evidence in court. That is to say, the only legally binding land surveys, private surveys included, were those done by the county surveyors. The reason is probably because there were few qualified land surveyors in the state at that time; this was long before surveying licensure requirements took effect on July 1, 1891. Evidently the founding fathers sought to minimize the effect of amateur surveyors. The county surveyor and his deputies were entitled to the following compensation: Ten dollars for the first mile run with compass and chain and eight dollars for each mile thereafter; five dollars for each mile run with compass alone; three dollars for each plat and certificate; five dollars for each lot laid out and plotted in any city or town; two dollars for recording a survey; and fifty cents for each mile for traveling to the place of survey and returning. Each county surveyor was directed to transmit copies of his field notes and plats to the surveyor general (except for surveys of city or town lots) and he was required to indicate plainly on his maps where rivers, streams, and parcel boundaries intersected county lines.
Duties of the Surveyor General California's first statutes authorized the surveyor general to survey, mark, and map the boundaries of the state, counties, incorporated cities, and towns. He was further authorized to require the county surveyors to assist him within the limits of their respective counties in the execution of any surveys authorized by the legislation. The statutes designated the surveyor general as chief engineer and commissioner of internal improvements such as roads, railroads, canals, and aqueducts. Curiously, there is no mention of a "county engineer" or "engineer general" in the first statutes. The surveyor general was directed to require county surveyors to collect and provide detailed information about the state's resources within their jurisdictions. Some examples of the information county surveyors were required to provide are as follows: • An estimate of the quantity of land within the county. • An estimate of the quantity of lands used for tillage and grazing. • An estimate of the number of horses, cattle, sheep, and swine. • An estimate of the quantity of wheat, rye, maize, potatoes, grapes, and other agricultural productions of the preceding year, together with his views as to the presence, cause, and remedy of any diseases preventing an increase of the same. • An estimate of the quantity and value of minerals produced, together with a description of the localities in which such minerals may be found. • All facts within his personal knowledge which may promote the full development of the resources of the state. The office of the surveyor general was eliminated by statute in 1929.
The County Surveyor Today A public officer of the State of California, the legislated duties of the county surveyor are today set forth primarily in the California Government Code. Other duties are defined the Business and Professions Code, Health and Safety Code, Streets and Highways Code, Public Resources Code, and Water Code. These duties are diverse and to some extent are carried out slightly differently across the state. Generally speaking, California's county surveyors provide the following services: • Educate the public regarding rights and obligations affecting property owners. • Review final and parcel maps, records of survey, corner records, lot line adjustments, property mergers, abandonment of public easements, offers of dedication, and similar documents for compliance with federal, state and local laws. • Store, index, and provide public access to land based records for research purposes. Many offices scan maps and other documents and enter them into an electronic database for easy access, and copies of records that are archived in other jurisdictions can often be found in the Continued on next page

office of the county surveyor. Depending on the county, documents available for research generally include the following: Final and parcel maps, records of survey, corner records, lot line adjustments, offers of dedication, certificates of compliance; unrecorded surveys; PLSS maps; swamp and overflowed lands surveys; highway maps; right-ofway maps; assessor maps; deeds; zoning maps; special district maps; annexation maps, county boundary maps; state boundary maps; and aerial images. • Create and maintain GIS maps and official documents for local jurisdictions including school, fire, utility and community service districts. • Determine boundaries of county owned properties, including roads, rights-of-way, easements, and county controlled districts. • Conduct surveys as required by the Board of Supervisors and the courts. • Provide data to the State Land Commission regarding county surveys that cross state owned lands such school lands, swamp and overflowed lands, tidelands, and navigable streams. • Authorize retracement surveys using monument preservation funds of historical land division lines such as government section lines, rancho lines, grant lines, rancho section lines, acreage subdivision lot lines, and subdivision boundary lines.

• Collaborate with other agencies in the land development process and provide support and expertise to other departments and jurisdictions for the benefit of the public. • Serve as ex-officio deputy county recorder and certify to the authenticity of certain documents in that capacity.

Do you have a picture of a “junior surveyor” in your family that you would like to share? Send it in and we will put it in the Kids Korner.
About the Picture The picture above was taken with an iPad using the app "Theodolite HD" by Hunter Research & Technology. The app uses the iPad's built-in GPS receiver and gyroscope to provide measurements of horizontal and vertical angles much like a theodolite. Just point the cross hairs at your target and read the measurements on the screen. My friend Karen Tolentino, EIT found the app on the internet and shared it with me because she knows I have an interest in surveying equipment. Karen has considerable experience with construction surveys using total stations and GPS as a staff sergeant in the U.S. Air Force. Technology like this theodolite app is a double-edged sword for surveyors. Technology makes our work physically easier and helps us get more work done faster with fewer workers. At the same time it presents serious challenges to our profession. Does the need for fewer workers translate into an ever-shrinking population of surveyors? And how will land surveying as a profession stay relevant in a world where everyone can make expert measurements? If you have thoughts about the impact of technology on the future of our profession please share them with us. We plan to address this important subject in future issues of the California Surveyor.

Mentoring: A Mutually Beneficial Relationship t my recent Chapter meeting I noticed many new faces, and a lot less gray hair in the room. We gave recognition to new Surveyors who were recently notified that they passed the LS exam. Can you remember the excitement and/or trepidation when opening the envelope from the BPELSG? I congratulate the new licensees for their accomplishment and wish them the best as they navigate through their career. Moreover, I extend a sincere thank you to those that chose to help advance our profession by mentoring a new generation of Surveyors. Your dedication helped these new licensees achieve their success and I know you share in the joy of seeing them attain licensure. (A full list of new LS’s can be found on page 23.
The value of mentoring within our profession cannot be overstated. In the beginning, mentors assist in teaching the information you need to take the first step - becoming licensed. However, true mentors continue to be there as a resource to help shape you as a professional and guide you through your career. I still rely on mentors; Surveyors to bounce ideas off of and gain different insight. Mentors aren’t necessarily your elder, some of my mentors are near my age, some a bit older, some a bit younger. All are colleagues, yet each have the unique quality of a mentor which is the willingness to listen, draw from experience, and suggest a fresh perspective. We all have unique abilities and areas of expertise and it is important that we continue the tradition within our profession of sharing knowledge and experience with the future generation. There is a lot to be gained by being a mentor. Not just the good feeling you get by helping someone, but a true value in facilitating your own professional growth by mentoring someone else. Knowing you are responsible for guiding someone helps to motivate you to look at your own performance and grow both personally and professionally.
Getting Involved The greatest benefit to be derived from membership in any professional organization is the opportunity to establish key relationships with others who are dedicated to the advancement of the profession. As members of the California Land Surveyors Association (CLSA), we are able to unite with our colleagues and through our association we can participate in the exchange of new concepts, ideas, and help solve problems that may exist within the surveying profession. In recent years, I have heard lively discussion on topics such as GIS, laser scanning, photogrammetry, and the role (or lack thereof) of the Surveyor. It is important we continue to talk about these issues and CLSA provides the means to do so. CLSA is unique in that we represent all Land Surveyors. Our membership includes private sector and public sector surveyors. This provides a vast networking resource and wealth of industry knowledge. One can attend local Chapter meetings which provide an opportunity to discuss topics and mentor one another. Another way to mentor is through the CLSA online Discussion Board. This provides a resource to widely share information throughout the survey community and beyond. However you choose to get involved, I encourage you to make a personal commitment to continue learning, teaching and supporting your peers. Respectfully challenge others and yourself with the intent of facilitating growth. Finally, encourage others to share their ideas. We must invest our time and expertise to continue moving the profession forward.

Letter to the Editor Dear Editor, I am writing to express my appreciation for Phil Danskin's article "Thank You for Your Interest" in Issue #173. I can relate to his advice: "Be prepared for competitors that, to put this generously, play by different rules than you do." You could also call it "playing by different rules" or "what CLSA members do NOT do." Like many intangibles, professionalism may be more easily defined by considering what it is not.
Proceeds from the sale of photos benefit California Land Surveyors Association Education Foundation (CLSA EF) and will be used to fund scholarships for land surveying students. CLSA would like to thank Bryant Sturgess for generously donating his collection of historic images.
I would add three specifics to Mr. Danskin's "be prepared" advice: 1.) Don't be surprised by what some notso-professional land surveyors are willing to say for money. 2.) When you are the target, and you will be sooner or later, don't feel like the Lone Ranger since it happens to all of us. 3.) Perhaps most important is to adopt a "let it go" (quickly) mantra. It is just like the unsportsmanlike conduct we see everywhere. Life is too short and you won't pay the bills if you let this stuff get to you and sap the energy you should be putting into your work. Remember the "fake Budda quote," no less valuable even if we may not know for certain the identity of the author: “Holding onto anger is like drinking poison and expecting the other person to die.” Stephen Hughey, PLS

http://www.sdcounty.ca.gov/dpw/surveyor.html SRS Expands In 2013, Cartographic Services completed an expansion of the Survey Records System. Called SRS Phase 2, this expansion doubled the number of documents available online, while also making some welcome user interface improvements.
There is now even less need for the public to travel to the County Operations Center to view and purchase records and documents, since almost all of Cartographic Services records are now online. However, if customers do come in to the office, they will have four new kiosks at their disposal to assist in the search for their records.

Survey Records System Simplifies and Expands Research Background County of San Diego staff, industry professionals and the general public, all need access to survey records and related documents stored by the County. Most of these documents were traditionally researched and retrieved using manual indexing systems and viewed and printed from aperture cards, hard copies and other analog materials. The Department of Public Works, Cartographic Services Section introduced the Survey Records System (SRS) in 2005. SRS is an online web-based records retrieval system that allows the public and county employees to geographically search for land-based records from their homes or offices and receive them electronically as downloaded images. The system has been received enthusiastically by the public and by County staff. The Center for Digital Government and Education recognized the DPW’s SRS with a 2005 “Best of the Web” Digital Government Achievement Award in the Government to Government category. Being completely web-based, SRS requires no software installation on users’ computers. They do need to make sure they have Microsoft Silverlight installed, but that is pretty standard now. So records are available from laptop computers connecting to the Internet from anywhere. Continued on next page 16

Web-Based Records Retrieval & Viewing System
SJSO Web Page
The Surveyor Division of the San Joaquin County Department of Public Works contains thousands of land and survey-related records within San Joaquin County. Historically, these records have been accessed at the Recorder's Office in downtown Stockton, or the County Surveyor's Office. With the Surveyor Land Records System, the method for accessing public records has been drastically changed by using a powerful web-based public records retrieval and viewing system. Records and documents are scanned and linked to corresponding geographic locations within the County Public Land Surveying System. Then records can be easily located and retrieved using a standard web browser from any personal computer connected to the Internet. Users can access Parcel Maps, Records of Survey, unfiled Maps, and Final (Subdivision) Maps in Maps and Plats.
The above hyperlink is the main page of the website for accessing images of record maps, records of survey and unfiled maps sorted by PLSS section. Within the vicinity of Stockton, the C.M. Weber grant is subdivided by sections as well.

Guidelines and Checklists County Surveyor Maps and Records The County Surveyor has a series of map books that date back to its creation at statehood. These are large bounded map books located at our counter. The County Surveyor was initially an elected official and early County Surveyors often had a private business in additions to the County Surveyor duties. The records for these early County Surveyors were kept together as a collection as best as possible. This is why there may be maps that are out of the County and a few that are in Mexico. The collections contain their maps and field notes. The most popular collections are the Herrmann and McMillan records. Currently these original records are kept at the County Surveyor’s Office. Other maps and records include the School District Maps which were used as the basis for the current County Assessors Maps. This is useful for researching historical land boundaries. The Road Files and Vault Maps are from the era when the County had a Public Works department before it was divided into the Santa Clara Valley Water District, County Roads & Airports and the Santa Clara Valley Transportation Agency.

By: Scott P. Martin, PLS Scott Martin is a Senior Transportation Surveyor in the Caltrans Office of Land Surveys in Sacramento specializing in GPS Surveys and Geodetic Control. He serves as the chairperson for the California Geodetic Control Work Group chartered by the California GIS Council. He is also a member of the California Spatial Reference Center’s Coordinating Council. The author would like to thank Marti Ikehara, retired NGS Geodetic Advisor to California, for providing technical and literary review of this article.
Positional Time Travel – A Discussion of the Horizontal Time-Dependent Positioning (HTDP) Utility hen John asked me if I would write an article for the California Surveyor on the NGS utility, Horizontal Time-Dependent Positioning (HTDP), I thought perhaps he had been in the sun too long, or possibly was taking a “dive” to undermine the publication after pressure from some of the competition. However, I told him I would consider the idea anyway. After all, trying to write something even remotely pleasing to read, on such a technical, dry topic doesn’t exactly get the literary salivary glands flowing. So here goes….well, I hope not… nothing.
Having worked in ever-moving California for all 36 years of my surveying career-- the past 13 or so on projects often involving the nowretired NGS Geodetic Advisor to California, Marti Ikehara-- I was aware of this software tool written by NGS called HTDP. In fact, I knew it was sanctioned in the PRC (8815.3) as authorized for use to align survey control to the same epoch date. I even knew that a user could actually input custom velocities, rather than using the defaults in the velocity model program. I knew enough that I could throw the term HTDP around like I had some level of expertise in the use of it. Truth was, until recently, I had never actually used HTDP. A few months ago, the opportunity arose for me to be involved in a project where the work was done in 2012, but, for various project reasons, the deliverables were to be referenced horizontally to NAD83(1992) epoch 1991.35 (a.k.a. the HPGN epoch). Suddenly, my years of letting HTDP roll off my tongue were about to be tested, because I was approached for input about how best this might be done. If California was a stable state, in a geophysical sense, the answer would be rather obvious and easy. However, this project not only was in California, but in the Bay Area, where there are dozens of fault zones. I had no clue how well HTDP would model the crustal motion in this complex area across more than 20 years of elapsed time. How would it treat the displacements: both “co-seismic” -displacement that occurs during the actual event, and “post-seismic” - displacement that occurs following the event, often for several months until things settle back to “normal” secular crustal motion? Heck I didn’t even know how to use the tool at all. Time to dive in and get educated I started by talking to Marti and others about HTDP. I read the User’s Guide for Version 3.2.3 on the NGS HTDP web page. One concern that some people I spoke with raised was that HTDP was not capable of accurately transforming positions across NGS realizations (adjustments) of NAD83, as would be needed in this case. However, I found nothing in the User’s Guide regarding this limitation – no warnings, no statements, nothing. What I learned is that NGS had chosen to not develop a tool to model between specific realizations of NAD83 because the error in the model approached or exceeded the amount of “shift” that resulted from the realization or adjustment. However, customer demand has resulted in
a Beta version of this type of tool now being available from NGS – GEOCON and GEOCON11). In other words, certainly in Caliornia, most of the change in the position of any given point over time was the result of secular crustal motion and seismic event displacement, not from an adjustment of NAD83 (such as the 2007 National adjustment). Thus, at least so far, HTDP has ignored those types of shifts. I also learned that HTDP utilizes blocks with assigned velocities (velocity grid files) and has been updated each time more data becomes available. When Version 3.2.1 was released, the velocity grid files along the creeping segment of the San Andreas Fault were reduced down to 0.6 minutes of latitude and longitude blocks, which was more than 6 times more refined than in previous versions. This tool has been ever evolving and improving. Based on this new knowledge, I now wanted to do some testing. Now keep in mind, I am not a scientist, mad or otherwise. I am a surveyor (mad or not is debatable) so the proof would be in the numbers for me. Because I was looking at a specific project, it made sense to perform my testing on the control being used for this project, rather than some random points. After all, my task was to determine how best to provide the deliverables referenced to the 1991.35 epoch for this job. I had to see if HTDP was part of my answer. In the project, there were three different sub areas that would be controlled independently of the others. Control points still existing in each sub area that had 1991.35 superseded coordinates on the NGS datasheet were sparse. Two areas had only a single point and the third had three. I decided to start with the one that had the most. Basically my thought was to transform the NAD83(2011) epoch 2010.00 published coordinates for the three points having 1991.35 superseded values using HTDP and compare the results to the original published 1991.35 positions, now superceded. I know, some folks say I shouldn’t haven’t gone “across” the 2007 adjustment, but this was a test, and I honestly believed that was not an issue, based on what I had read and learned. Okay, here is where it gets tough to keep any literary style or flow going – the number crunching. The three points I started with, PID’s AA3807 (GPS CONTROL POINT 10), AA3819 (HPGN D CA 04 GJ), and HS5109 (GOLD CREEK), are located along Highway 680 in the Pleasanton to Lafayette area, generally a north-south route. AA3807 and HS5109 are spaced almost 17 miles apart with AA3819 near the mid-point. They are near the Calaveras Fault alignment based on some geologic resources I consulted. In HTDP, I selected the “Interactively update positions and/or observations to a specified date” option (See Figure A). There was only one Continued on page 26
Continued from page 24
Positional Time Travel
NAD83 option for the input reference frame for the North American Plate-- NAD83(2011/CORS96/2007)-- which confirmed that HTDP considers these all the same with regards to the transformation parameters.
Figure A I started with the NAD83(2011) 2010.00 latitude, longitude, and ellipsoid height from the current data sheet for point AA3807, so 2010.00 was the reference date for the input position. Note that there are two date format options for input (See Figure B), month-day-year and decimal year, so be sure to select the correct option. My output reference frame date was 1991.35.
Figure C I input the Lat/Lon/Ellipsoid height from the data sheet. I then selected the option to use the HTDP predicted velocity for the transformation (See Figure C) rather than customizing (I’ll talk more about that later – oh joy) and let the program do its thing. I repeated this for the other two points, PID AA3814 (HPGN D CA 04 FH) and HT2440 (W 1446). Figure D shows the results for the linear differences between the Superseded published 1991.35 and the HTDP-derived 1991.35 coordinates.
You may be wondering why I’m showing the 2011 Network Accuracy data. Each NAD83 (2011) set of horizontal coordinates has an accuracy shown on its Datasheet that indicates how close NGS believes this adjustment of the NAD83 coordinates come to ‘truth’. The range for these 5 points is 0.51 cm to 0.82 cm, with an average of 0.71 cm. This represents the ‘error’or inaccuracies in the “HTDP’d coordinates” even before using HTDP model, which has its own set of errors. Continued on next page
Continued from previous page It appears the HTDP velocity grids are roughly twice as accurate in the Northing than they are in the Easting for points translated back to 1991.35. Also included in the table are two points (AA3814 and HT2440) located along Highway 880 between Union City and San Leandro near the Hayward fault. These points are about 12 miles westerly of the first three mentioned above. Point HT2440 did not have a 1991.35 superseded value, but it did have a NAD83(1998) epoch 2002.75 value from a Height Modernization survey, so the comparison shown above relates to the 2002.75 value. It is interesting to note that the transformation for this point also went across the 2007 National Adjustment, yet the calculations are within a centimeter. In my feeble mind, that tells me that going across the 2007 Adjustment introduced very little error, if any. The amount of error seems to be much more a function of time elapsed, based on this very small sample.
As you can see, HTDP was able to model back to the original 1991.35 published position (or 2002.75 in the case of HT2440) within a couple centimeters (on average) when the estimated network accuracy error is removed. The misfits to the published coordinates were directionally consistent, as well. Even though these points are in a fairly small area, I noted that each of them had a slightly different predicted velocity in HTDP (both in north and east), which shows how refined the velocity grids are in this area. Although this is a fairly small sample set, and by no means a rigorous statistical analysis, my results show that HTDP is a pretty darn good modeling tool given that, for example, the predicted velocity rates are up to 25.56 mm/year (latitude) by 17.25 mm/yr (longitude) for point AA3814 for a total displacement between 1991.35 and 2010.00 of 0.477 meters north and 0.322 meters west. I believe these results also show that going across the 2007.00 realization of NAD83 likely contributed very little error to the transformation. I was pretty pleased by the results of this limited testing, but I wasn’t done yet. For the area near Hayward along Highway 880, I retrieved information for four NGS CORS stations in the vicinity, specifically the NAD83(2011) –not IGS08—velocity information, from NGS CORS Coordinate sheets (http://www.ngs.noaa.gov/CORS/data.shtml). These stations are: DH9021 (P222), DO2391(WINT), DE6356 (ZOA2), and AF9690 (CHAB). I did not compare their locations to mapped faults, which in retrospect, would have been better science. Maybe next time? I then computed an average velocity in the north and east directions. Then, I went back into HTDP, but instead of using their velocity predictions, I entered the ones averaged from the four CORS stations (using the northeast-up components option) and transformed AA3814 again. See Figure E for the results. One thing to note: If you look closely at the bottom of Figure C, where the custom velocities can be entered, you will notice an error. It says “North or X (mm/yr)” and “East or Y (mm/yr)”. This is a common mis-
take. I experimented and determined that the North box is just that (and not X) and the same for the East box. Also, remember that sign is important. In this case, and essentially all of California, the custom velocity for the East component had to be entered as a negative number. As you can see, the results are still pretty good –acceptable for most applications. I would say that, seeing the marked difference in velocities, the first three CORS stations listed in the table are all moving together and the last is likely across a fault(s) from the other three. Further analysis would be required to make this determination, which could result in removing the last CORS station from the average calculation. What entering these “custom” velocities doesn’t do is account specifically for any co- or post-seismic displacements for which the HTDP grids do. Furthermore, CORS velocity vectors are used, along with other sources of data, including CGPS, to develop and improve the velocity grids in HTDP. Therefore, it’s not reasonable to think one could improve on HTDP by using a small CORS or CGPS sampling, unless it was suspected that the velocity grid file in HDTP covering a specific area could be improved by isolating the velocity used to very specific CORS/CGPS stations in the immediate vicinity of your project, if available. It would be akin to developing a localized custom geoid model by using denser, localized data, but that is the subject of another article, at another time, by a different author! My conclusion was that HTDP could be used to transform other control in this project from the published NAD83(2011) epoch 2010.00 position back to 1991.35 and expect the results to be within a previously published 1991.35 position within 2-3 centimeters, possibly better. The proof will ultimately be in the network adjustment statistics and analysis of the project’s observations, but I am confident the work will meet the specifications for this project. No wonder the California Public Resources Code endorses the use of this utility to align survey control to the same epoch date. For this small sample that I researched, it worked well, even in one of the most complex geophysical areas of California. While I am not an HTDP expert now, at least I can honestly say I have used it.

Seam Errors on a Digital Bar Code Level Rod o you got your new bar code digital level to do that first order work your new client requested. Nice. And you bought the three section rods, understandably, because the one-piece invar rods are so darned expensive and a little difficult to carry around. How good is the rod reading value at the top? Is it really 4 meters? Or is it 3.999 meters? Or worse, you really don’t know? These rod seam errors – a back sight reading either below or above a seam and a foresight reading on the other side of one or even two seams – might accumulate enough in a level run to affect the accuracy of your benchmark elevations and closures. They can be identified and eliminated, particularly with level runs having extreme elevation differences between setups.
The calibration form (Figure 1 - Opposite page) is a method to identify the seam errors on a digital bar code leveling rod with sections. Once you have these numbers on hand, you can apply them to your level runs to improve accuracy. The other advantage is that your clients will understand your conscientious and scientific approach to the technical side of surveying.
The Setup The procedures below are for one rod. Complete the calibration form for each rod. Set up an area (concrete steps make a pretty good test site) with stable, well-defined benchmarks, approximately 2-3 feet difference in elevation. Set up the level so it sees the bottom section of the rod on both benchmarks. Note that you should be at least 20cm or 6”below the seam and 6”above the bottom of the rod, and about 3-6m or 10-20 feet away from the rod. You don’t want the field of vision of the sensor reading the barcode as it crosses the seam.
First Reading Read the rod’s bottom section on Benchmark “A”. Read the rod’s bottom section on Benchmark “B”. The difference between the rod readings is the apparent true difference between “A” and “B” (H1). 28
Second Reading Set up the level so it sees the rod’s middle section on “A” and bottom section on “B”. Read the rod’s middle section on Benchmark “A”. Read the rod’s bottom section on Benchmark “B”. The difference between the rod readings is the difference across the seams between “A” and “B” (H2). The difference between the H2 and H1 is the rod seam error between the bottom section and the mid-section.
Third Reading Set up the level so it sees Rod’s top section on “A” and mid section on “B”. Read the rod’s top section on Benchmark “A”. Read the rod’s middle section on Benchmark “B”. The difference between the rod readings is the difference across the seams between “A” and “B” (H3). The difference between the H3 and H1 is the rod seam error between the middle section and the top section. This procedure and form was used quite successfully on a city-wide leveling project in the City and County of San Francisco. We hope this helps with your projects as well. Too easy!

Professional Outreach Events
One of the Guys
By Annette Lockhart, PLS – Director and Immediate Past President, Sacramento Chapter
A few years ago, I was visiting Northern Counties Chapter for the first time. The extra spark to their meetings is that there are almost as many spouses as there are members in attendance. That night Barbara Solheim (wife of Don) invited me to speak at an event for 7th and 8th grade girls at Yuba College – the Math Science Conference. I have been participating in the yearly event ever since.
Photography: Artis Buerki Publicity Plus Marketing
The girls from the local Yuba-Sutter Middle Schools attend the Math Science Conference with their math or science teachers as part of their school curriculum. Each student at the Conference has selected in advance three areas of interest to learn about that morning. Presenters in each session are women from professions that utilize math and science in their practice. The objective of the Math Science Conference is to introduce the girls to career opportunities in the fields of math and science while they are still in junior high, and to encourage them to stay in school and plan for a career.
The event is sponsored by Marysville-Yuba City Branch of the American Association of University Women. AAUW has been empowering women as individuals and as a community since 1881. AAUW believes in the value of educational programs that encourage girls to succeed in these traditionally male-dominated fields and introduce girls to female role models. AAUW creates programs that offer girls the opportunity for hands-on activities while also exposing them to a multitude of educational and professional options. In the past, Jill Van Houten has assisted me, but this year I was on my own. This year we talked a little about GPS and went outside to learn about contours with the help of a plastic box, food coloring, and markers. (See accompanying pictures by Artis Buerki.) As with Trig Star, I like doing these events because I am a big fan of surveying. I am truly convinced that if given the opportunity everyone would join our team. I know some of you actually knew that surveying existed as a kid, but I did not. It took me a while to find it. I just want to spare other kids that kind of pain.
Surveying Goes to Tustin By Don Mertens, PLS
rank Romano and Robert Rinella from the California Department of Transportation (CALTRANS), along with Kari Irwin (Business & CTE) and Don Mertens (Surveying) represented Santiago Canyon College at the Tustin Unified School District College Day on Friday, May 3, 2013.
Approximately 600 high school students participated in this hands-on career fair with 30 college and educational institutions showcasing their programs. Students who stopped by the Santiago Canyon College exhibit table not only learned about the educational paths available, they also had an opportunity to learn about careers in the surveying field with interactive survey equipment on display.

A Call to Alms Dear Land Surveying Professionals: ublic schools have faced severe funding shortfalls due to the downturn in the economy. Small programs like Geomatics Engineering at Fresno State are under increased scrutiny for closure as a means of cutting costs by the university. Dr. Crossfield is in semiretirement. Dr. Ogaja resigned from the program in February. Fortunately, some graduate students (Scott Roberts, Chase Miller and Travis Bohan) stepped in to teach his classes and Dr. Nader, though retired, picked up a class or two. But this is a temporary fix that is not sustainable and a new professor is actively being sought. CSU, Fresno will likely not be willing to fill the position without outside means of financial support due to the small size of the program. There is a very real danger the university will see this as an opportunity to shutter the program and save itself some money.
The CSU, Fresno Endowment Fund was established to subsidize the salary of a new professor. Matching funds from the Lyles Foundation for donations made by September 2013 will double your donation. For example, should you decide to donate a $500 dollars, your donation will be matched dollar-for-dollar by the Lyle Foundation making your donation $1000. The goal is for $750,000. You may have noticed that many CLSA Chapters and individuals have already donated, as chronicled in the California Surveyor magazine and on the CLSA website. CLSA and its affiliate Chapters have been incredibly supportive of their surveying students. Now it is the Geomatics program itself that is in danger and we face the very real possibility of losing California’s only four year ABET accredited land surveying program.
In fact it was the country’s first four year ABET accredited land surveying program, receiving its accreditation in 1978. Robert Parsons (RIP) from the Monterey Bay Chapter was the first graduate in 1971. The degree began as Surveying and Photogrammetry, transitioned to Survey Engineering and it is now called Geomatics Engineering. The curriculum includes land surveying, geodesy, photogrammetry and GIS. But most importantly, the program teaches professional stewardship and leadership skills. Students are taught very early to join and participate in CLSA, ASPRS and NSPS. They learn the value of teamwork and continuing education by volunteering in the annual CSU, Fresno Geomatics Engineering Student Conference. To date there have been over seven hundred graduates. Unfortunately, that’s only about 16 a year and enrollments are falling. Anything the profession could do to help encourage enrollment would also help greatly. Bill Hofferber speaks to this in his recent April CLSA Education Foundation report. Please consider speaking to your local high school students about our profession. I wish I had learned about it sooner, as I feel it is the greatest vocation in the world. The loss of the availability of this program to future surveyors would be a tragedy. I feel so strongly about this I will be donating $1000 before the September matching deadline; I hope and trust that other CLSA Chapters and members will do the same. Consider it an essential investment in the future of our profession. Sincerely, David Biswanger, LSIT, MSCE Secretary, Monterey Bay Chapter CLSA Editor’s Note: David Biswanger is a Fresno State graduate and currently works for the East Bay Municipal Utility District.

France officially introduced the metric system in 1799. Although it was decreed that its use was to be mandatory in Paris that year and across the provinces the following year, the decree was not universally observed across France. In 1812 Napoleon introduced a system known as mesures usuelles for retail trade that was based on the kilogram and meter. This laid the foundation for the definitive introduction of the metric system across Europe. – from Wikipedia

RISK MANAGEMENT FOR LAND SURVEYORS
Certificates of Insurance - Check Them Out ext to your actual insurance policies, your certificates of insurance are your most important insurance documents and must be accurate and thorough because you use them to get jobs, to get paid and to let your clients-owners, contractors, municipal entities know that you are complying with the contract requirements that you agreed to when you took the surveying job. Here is a sample certificate with explanations of what needs to be included:
I am also including a checklist for all policies that come from The National Underwriter Company, Inc. I have edited and modified the original document.
Checklist for All Policies Each type of insurance has its own exposures and coverage requirements but there are many common items that apply to all property and casualty policies. 1.
Legal name of insured-is it correct and complete?
Legal status-individual, sole proprietor, partnership, corporation, limited liability corporation (LLC).
Location and address-correct and complete?
Amounts of insurance or limits of liability relative to values or exposure?
Additional insured interests to be included-mortgage lenders, loss payees, persons with a contractual or financial interest?
Correct inception and expiration dates and premium payment method?
Accurate and complete policy declarations?
Compliance with policy warranties, agreements or stipulations?
10. Policy language is standard and current? 11. Concurrence with all other policies-contributory, primary/excess, other insurance clauses? 12. Coverage duplications among the policies? 13. Rates, classifications and premiums-are they proper and complete? Proper credits allowed for experience, size, risk dispersion, revenues and deductibles?
Rates Going Up Again Rates will be going up from 7 to 10% in the next year according to many experts. That’s all the more reason to be accurate and complete with your policy reviews, value and revenue reporting. Also it would be a good idea to start your renewal process a month or two ahead of time this year.
14. Loss experience considered for present policy rates or premiums and terms? 15. Insurance requirements of leases and contracts considered? 16. Current risk management and continuing education con sidered by underwriters?

Q& A SMA Expert Question First, what are the “rules of contiquity?” And second, when the common owner of two contiguous lots forms a “Trust” and puts that contiguous land into the Trust, after the landowner’s death, is the Trust considered to be the “same” owner (for purposes of determining what type of map to use) as the landowner who formed the Trust?
Discussion Great question! Here are my thoughts.
enerally, the “rule of contiguity” holds that when a “common owner” of real property seeks to divide a parcel of land that is “contiguous” to another parcel of land likewise owned by the same owner and which other parcel was previously subdivided by the same owner, the two divisions are counted together (the older division’s lot count is added to the newer division’s lot count) in order to ascertain the total number of parcels created over time, and therefore to determine what kind of map (Tentative or Parcel) the current subdivision proposal will require. While generally “contiguous” means sharing a common border or touching, the Map Act expands the definition and considers property to be contiguous even if separated by roads, streets, drainage canals and other similar public improvements (see, Map Act section 66424). So, for example, if an owner purchased two contiguous lots (Parcel A and Parcel B) from someone else, and then divided Parcel A into 4 lots, he would use a Parcel Map (creation of 4 or fewer lots). If some time later, he decided to divide Parcel B into 2 lots, that lot-split would require a Tentative Map, because counting the lots he created earlier on contiguous property (4 lots on Parcel A), the lot-split division on Parcel B actually created the 5th and 6th lots on “contiguous” property, and therefore, that lot-split division must be done with a Tentative Map (division resulting in 5 or more lots requires a Tentative Map).
This is the rule, even when the divisions are separated by time. In Bright v. Board of Supervisors, 66 Cal. App. 3d 191 (1977), a subdivider owned two adjacent parcels. He owned the first parcel as his own separate property, and he owned the second property with his wife as joint tenants. Then in 1971, the owner transferred a portion of the second 38

property to his wife as her own separate parcel. In 1973, he then applied for a parcel map proposing to divide the first property (his separate property) into four lots. The court held that the 1971 division and the 1973 division had to be counted together for purposes of determining whether a Parcel Map or a Tentative Map would be required. In so counting, his 1973 proposal was actually creating 6 total lots (when his 1971 and 1973 divisions were added together), thus a Tentative Map was required for his 1973 4-lot subdivision proposal. The fact that the second division occurred later in time did not matter to the court. As long as the same common owner (subdivider) had an interest in the contiguous property being divided, the passage of time between divisions did not change the fact that ultimately, the common owner of contiguous property caused five or more parcels to be created; the map that causes the lot count in total to go to 5 or more must be a Tentative Map, regardless of how many lots it, alone, is creating. Applying those rules then leads to the second question: Is a Trust a separate and distinct enough entity - from the landowner who creates the Trust – so that the rule of contiguity would not be applied if, after the landowner’s death, the Trust (as the owner of Parcel B) seeks to divide Parcel B into two lots. In my opinion, the Trust should not be treated as the same owner as the landowner. While I do not pretend to be an expert on Trusts, I do know that the Map Act “resets” each time a new owner is in the picture. In other words, if instead, the landowner had given Parcel B to his daughter, the daughter should not have the earlier Parcel A 4-split held against her (the rule of contiguity would not be applied) when she applies to do a lot-split on Parcel B, because she was not the owner of Parcel A, her father was. My limited understanding of Trusts is that they survive the Trust creator’s death because they are considered a legal entity separate and apart from the Trust creator. As such, the Map Act should view them as a new owner of Parcel B, not the old owner of Parcel B (the landowner who created the Trust). Therefore, if the Trust is considered the new owner of Parcel B, then the rules of contiguity regarding the old owner (the landowner who formed the Trust) should not apply. Again, this is my opinion. Thanks again for the great questions!

The BPELSG Chronicles BPELSG and the County Surveyor
he connection between the county surveyor and BPELSG is beneficial to the profession of land surveying. The county surveyor has the opportunity to review much of the surveying that goes on every day all across California. While the duties of the county surveyor are set forth in various portions of the Government Code and related regulations, the primary interaction with BPELSG and county surveyors is related to the PLS Act (Business and Professions Code, Division 3, Chapter 15, §§8700-8805) and Board Rules (California Code of Regulations, Title 16, Division 5, §§400-476) . Quite often, the county surveyor supports BPELSG with enforcement cases and communication to the local communities. However, just because the county surveyor works in concert with BPELSG does not mean they are exempt from following the standard of care commonly known as the PLS Act and Board Rules. Complaints are received by BPELSG related to licensed or unlicensed practice; the individual submitting the complaint is referred to as the “Complainant” and the subject of the complaint is referred to as the “Subject”. To begin the investigation, Complainants are asked to provide supporting documentation. However, when the Complainant is the client of the Subject or a general member of the public, BPELSG will more than likely need additional relevant documents and record maps to even begin the investigation, which the client or general member of the public may not be aware of. When the Complainant is a professional surveyor, BPELSG often times still needs additional information. The best resource for copies of many of these documents and maps is the county surveyor. County surveyors are extremely helpful and vital to the investigation by providing copies to BPELSG in a timely manner. Additionally beneficial to BPELSG is the fact that county surveyors submit a good portion of the complaints relating to failure to file (or complete the filing of) records of survey and corner records. Don’t forget surveyors in California have had a filing requirement for their surveys since 1891! And, at that time, the minimum discipline against the licensee was revocation of the license for at least one year. Recently, county surveyors’ complaints outnumber other surveyors’ complaints for these types of violations. And I would say it isn’t because practicing land surveyors don’t see violations on a regular basis. My personal experience prior to my working here at BPELSG with other surveyors not wanting to submit a complaint to BPELSG is they don’t want to appear to be “judging” their brothers and sisters in surveying. The sad commentary on this statement is that it appears to be a small number of professionals who “fail to file” and everyone in the area knows the names of these individuals violating the laws. Is the best approach to only complain and do nothing else? I would say “no,” but that is a topic for another day. Another comment I have heard other surveyors say is, “Surveyors haven’t filed records in our area for years! I didn’t think it was really a requirement for all surveys.” Let’s just say regional incompetence is not a free pass.
County surveyors can also be a partner in communication with the public and surveying community by distributing BPELSG publications like the Consumer Guide and the Guide for City and County Officials. Some county surveyors have helped communicate Monument Conservation requirements to local cities. County surveyors have also worked with BPELSG to develop practices and procedures to protect and replace our cadastral infrastructure…monuments within their own jurisdiction. The PLS Act and Board Rules detail the county surveyor’s roles and responsibilities in regards to record of surveys and corner records. The county survey must examine record of surveys and corner records in accordance with Sections 8766 and 8773.2 of the PLS Act, respectively. After proper examination of these survey records, the county surveyor must sign the required statements for each. Is the signing of these statements merely only a ministerial action? Unquestionably - NO. Prior to signing any of the required statements, the county surveyor must exercise their professional experience, judgment and application of the laws and regulations related to each survey record. Only then should the county surveyor sign those survey documents. Am I saying that a surveyor needs to change the methods or procedures that they used for their survey because a county surveyor demands they do the survey using a specific method before the county surveyor will sign the document? Absolutely not! However, a surveyor may want to take the county survey’s counsel seriously because the county surveyor generally has a good understanding of local issues, standard of care, and has the opportunity to see far more surveys than the average surveyor performs in their career. In my experience, many county surveyors have added great value to the survey records that are submitted to their office. This has benefited both the public and the professionals alike. Interestingly though, county surveyors’ contributions to the surveying community have varied across the state and over time. The same is true for interaction with BPELSG. Some counties rarely, if ever, contact or assist BPELSG. Budget issues and newly appointed county surveyors can strain the collaboration with BPELSG. Where there is poor or no partnership everyone loses some benefit. Budgets aside, the county surveyor has played a vital role in the development and growth of California and is critical for the continued success in future development. Understanding of laws, regulations, local ordinances, and historic surveys are invaluable resources for the surveyors, the public and BPELSG. For BPELSG to best protect the public, it is vital the relationship with county surveyors continue and improve each day.

"CLSA is sponsoring a free retirement clinic at the Hall of Science on the campus of the University of Thana Ana. This year's theme: Quit while you are still alive, there have been too many surveyors who died while counting the months 'til they could retire. All those attending should look for the bright orange survey party sign and the cardboard cutout of the theodolite taped to the wall. All attendees will receive either a red or orange balloon courtesy of CLSA." Submitted by B.J. Tucker Expose yourself to science." – Submitted by John Wilusz

Bad Backlights Dear Mr. C.de Baca,
ur software programming department has received your latest letter and we want to express our appreciation for your concern. Your overwhelming knowledge of certain surveying techniques, especially those of a ‘mature’ nature, seems effortlessly demonstrated every time you address our humble firm. Please know that we always value your unique input and we sympathize with your desire to see, as you put it, “critical enhancements” to our suite of hardware and software products. However in these lean economic times we find ourselves with very limited resources and must maintain our focus on certain more pressing issues, specifically those likely aimed at a larger market. We are confident that you will be pleased to note that our programmers hold your correspondence is such special esteem that many of your letters hang framed on the walls of our Research and Development department. Where, we wonder, do you get the energy to offer us all these ideas? With respect to your latest communication, many among us recognize both the economic and environmentally conscious aspects of your suggestion. Any efforts made to use less energy and “green up” the surveying profession are both noble and practical.
Nevertheless, it is with no little melancholy that I am compelled to inform you that we are presently unable to devote resources to constructing an interface between our software and the Wild T-1. We certainly agree that this particular instrument is, as you so emphatically assert, “the best instrument ever made for stadia measurement”. While we regretfully decline to undertake this effort, I must inform you that some in our R&D department are still vigorously debating your previous request. Surely, the merits of adding a floppy disk drive to our flagship GNSS receiver and /or our top of the line survey controller speak for themselves, but no one is sure that a reliable source for floppy disks can be secured. I must say, however, that certain of the staff seem to have taken a particular delight in working on a prototype during their break time. Please do not let this temporary setback dissuade you from continuing to bring your enlightening suggestion to our attention. Sincerely yours, C. Spaught Runne Director of Development Squimble Geospatial, Inc.

ragging rights for the longest running set of tidal data collection in the western hemisphere goes to San Francisco. Currently we are at 159 years of data collection and counting. At Fort Point on June 30, 1854, a self-registering tide gauge was installed. This location was abandoned in 1877 because the infrastructure fell into disrepair. Data was collected in Sausalito beginning in 1877 and was discontinued in 1897 and operations move backed to the Presidio. This new Presidio location was about mile east of Fort Point. There were periods of overlapping operation of these tide gauges during their various moves The last move came in 1927 to a location just west of the Crissy Field Air strip to what is known as the Fort Point Coast Guard Wharf.
The first self registering tide gauge in the United States by the Coast Survey was constructed by Joseph Saxton , of the Office of United States Weights and Measures.
