Los Angeles Construction Tops New York bv $l Billion

Construction in the five-county Southland economic complex of Los Angeles, Orange, San Bernardino, Riverside and Ventura Counties exceeded building in the New York metropolitan area by more than $1,000,000,000 during the past five vears.

James S. Cantlen, chairman of the Research committee of the Los Angeles Chamber of Commerce, announced the results in a construction comparison study just completed by his committee. Figures compiled by the group showed that the Los Angeles area has surpassed its eastern counterpart in every year since 1954 to compile a total of $8,683,200,000 for the five-year period through December 31, 1958, compared with $7,677,000,000 for the New York-northeastern New Jersey complex, which includes 17 counties.

Twenty-one revised and three new standards for inclusion in the AW-PA Manual of Recommended Practice have been issued to all who have purchased copies of the Manual. The publication of these standards has been announced by the American Wood-Preservers' Association.

The revised and new standards incorporate recommendations of Technical committees of the association, approve<l at a recent annual meeting and later confirmed by letter ballot vote of all members of AW-PA.

Included in the new standards are specifications for the preservative treatment of plywood by pressure processes, the pressure treatment of wood for use in mines, and a listing of trade names of water-borne preservatives and fireretardant formulations, the designations of which have been changed in existing standards.

The standard for pressure treatment of lumber to be used intuildings has been completely revised.

two areas, Cantlen said the report showed that 135,000 more houses were built locally. This, he said, is more than enough housing to accommodate the entire population of Fort Worth, Newark, Indianapolis or Columbus, Ohio. Both metropolitan areas reached a home-building peak in 1955 in the period measured, when the I-os Angeles area recorded 125,963 new units and the New York area tabulated97,l89.

Last year, the report showed, the Southland recorded new construction surpassing the Empire City by more than $200,000,000 or $1,811,000,000 versus $1,580,900,000. Construction in Los Angeles and Orange Counties alone came close to New York's entire 1958 total when the two local counties recorded $1,540,200,000 last year. The report disclosed that the two counties actually passed the New York area in total new construction in 1956, by $1,579,600,000 to $1,547,600,000.
