1980 ADJUSTMENT

PREFACE1980 Adjustment

The Road Depament level net published in 1975 consisted Ðf more than1500 mies of levels supprtin in excess of 18,000 bench maks. Forreasons of economy, this 1980 adjustment is reduced to about 55% of thebench marks previously published. Reductions were made by increasin thespacin between level lines in uncorprated territory, and elimtinglines in non-contract cities and areas where the probability of futureengineering projects appears slight. The 1980 adjustment is an updte ofthe reminder of the 1975 bench marks, not includin baselines. Datafrom previous adjustments is availble without inerrin an responsibilityfor the curent reliability of. the data or the actua existence of the.bench maks. Elevations of bench maks with the same qud nae, butdifferent adjustment dates, are not normy comptible.

To facilitate the adjustment, indexi, and distribution of adjusted valuesof the net, the County territory is divided into 34 quads or areas. Foridentification puses each quad is given a nae, viz., "Rosemead,""La Mirada," "Santa Fe," etc. When bench maks and elevations in the RoadDepament net are used, the nae of the qud in which the bench mark islocated and the date of the elevation adjustment must be included in thebench mark description, e.g.,

CY 6901 - RDBM TAG S CB 11 FT E BCR (§ SE COR LA CIEABLVD & LENNOX BLVD 32FT S & 73FT E CIL IN(HAWTORN - 1980) ELV. 82.549

The precision of the net is reflected by an indicated field probable errorof plus or mis 0.012 foot per mie of levelin as determed from over 300conditions of closue. However, may years experience in vertical controlin the greater Los Aneles basin and Antelope Valey indicate that becauseof varin degrees of subsidence and heavi, the true datum is recoveredonly, by obtain substantia agreement between a number of bench marks.

The users of this net are invited to assist in its maintenace by notifyinthis Depatment of cases of obliteration, apparent mistakes in descriptionsor elevations, and proven disturbance of bench marks.

DATU: U. S. Coast and Geodetic Survey Sea Level Datumof 1929, through the medium of the Los AngelesCounty Engineer Precise Level Net.
