Workman, P.L.S. - Chief of Survey/City Surveyor 380 A Ave Lake Oswego, OR 97034-0369 (503) 635-0276 E-mail: tworkman@ci.oswego.or.us Amended: January 2, 2019 Page 1 of 17 Printed 1/2/2019 NARRATIVE (By: Gerald B. King, P.L.S. - Chief of Survey - 1986 to 2016) PROGRAM Prior to 1986 the City had accumulated over 350 vertical control benchmarks of varying and uncertain accuracy. Most of the benchmarks were points on fire hydrants or spikes in power poles. Because of disturbance to these benchmarks and the lack of unique identifications for each one, it was determined that an accurate, precise and uniform level network was needed. Beginning in August 1986 the City's two-man survey crew set out to establish a precise vertical control network using uniquely stamped brass disks. The city was divided into '/4 mile square grids using the U.S. Public Survey section lines as a guide to the grid lines. The equipment used included a Hilger-Watts Autolevel#256809, Lietz "Precise" 2-piece 13'rod, with rod bubble and heavy wooden frame Lietz tripod. Most benchmarks are 2 1/2" brass disks either glued with epoxy to the top of curbs or set in fresh concrete. Generally, P.K. nails set at an angle were used as turning points. The level was periodically pegged on a 200' course, but was never found to be significantly out of adjustment. All rod readings were 3-wire levels with a maximum length of sight of 150' (generally 100'-120') and care was taken to roughly balance the lengths of foresights and backsights. Differences between upper and lower wire intervals of over 0.005'were rejected and reshot. On December 17, 1996 the City Council passed Ordinance No. 2140 which adopted the National Geodetic Vertical Datum of 1929 (NGVD 29) as the official City datum for all vertical control within Lake Oswego. This new datum supersedes the "old" local City datum that had been in use for the last sixty years. To convert an"old" datum elevation to the"new"NGVD 29 datum you must add+1.997 feet to the record elevation. This edition of the City of Lake Oswego Benchmark Book shows all elevations in the "new"NGVD 29 datum. Between August 1996 and March 1998 the City contracted with Orbitech, Inc. (Shelby Griggs, PLS)to perform extensive GPS mapping throughout the City. He established elevations on many BMs that have never been tied to the City network. These elevations are shown to the nearest 0.1' and noted with the symbol (—). While checking into dozens of BMs that were tied to the City network his elevations generally checked to within 0.1' of the record elevations. These (—) BMs shall be considered secondary and should always be checked against a primary benchmark. FINDING A BENCHMARK To find a benchmark, first consult the map at the back of this index and determine the grid number and letter in which your project is located. All benches are listed by grid number, then letter order. If more than one benchmark is located in your grid square,be sure to note the suffix number and read the description carefully to be sure of the correct location. At this writing we have established over 225 benchmarks and eventually plan to have approximately 300 benchmarks, with at least one bench in each of the City's 260 one-quarter mile square grids.

In general,City of Lake Oswego elevations agree very well with ODOT,USC&GS,and COP record elevations.More specifically,Lake Oswego elevations tend to be stated approx.0.05 feet lower than other jurisdictions on the W. side of town(vic.I-5),we are in very close agreement in First Addition area and our elevations tend to be stated approx.0.02 feet higher in the NE&SE parts of town(vic.Hwy 43). The only bench exceeding 0.10 foot discrepancy is BM 18E-1 which I feel fairly certain has a published transposition by the USC&GS. Jerry King 12/27/96. Page 17 of 17 Printed 1/2/2019
