HIGH VISTA QUAD

(LANCASTER EAST)

1968 ADJUSTMENT

NGVD29 DATUM

PREFACE

The R 0 a d Departrre nt level net is composed of more than 1,000 miles of levels

supporting in excess of 10,000 bench marks. In 1964-65, a major readjustment of thenet was undertaken. To emphasize the complete break with previous elevationS, theSY, SG & SL series bench marks have been re-Iabeled BY, BG & BL, respectively.

To facilitate the adjustment, indexing, and distribution of adjusted values of the net,the County territory was divided into 31 quads or areas. For identification purposes

each quad was given a name, viz., "Rosemead," "La Mirada," "Santa Fe," etc. When

bench marks and elevations in the Road Department net are used, the name of thequad in which the bench mark is located and the date of the adjustment of the eleva-tion must be included in the bench mark description, e.g.,

BG 1887 --L+BN IN CONC HDWL OF DRAIN PIPE UNDER DR 218 FTNE +18 FT SE CIL INT GRAND AVE +CAMERON AVE MKD (BM)(COVINA --1965) ELEV. 696.238

It is expected that this general adjustment will, for the most part, remain sound for

the next 8 to 12 years. As new Circuits are completed, however, re-adjustment of

individual quads may become advisable. It is expected that these subséquent ad-

justments wil be in the nature of a few hundredths of a foot. When a quad is re-

adjusted, new elevation lists wil be published and the dat e of the re-adjustment

wil replace the" 1965" at the end of the bench mark description. Two bench marks

in the same quad with different adjustment dates will not normally join each other.Since all adjustments taper out to nothing at the periphery of the quad, any bench markin one quad wil join any bench mark in another quad regardless of their respectiveadjustment dates.

The basic accuracy of the net is reflected by an indicated field probable error 0 fplus or minus 0.012 foot per mile of leveling as determined from 298 conditions of

closure. However, many years experience in vertical control in the great erLosAngeles basin and Antelope Valley indicate that because of varying degrees ofsubsidence and heaving, the true datum is recovered only by obtaining substantialagreement of a number of bench marks.

The users of this net are invited to assist in its maintenance by notifying this De-

partment of cases of obliteration, appare nt mistakes in descriptions or elevations,and proven disturbance of bench marks.
