In addition, several new or <br />expanded elements were developed from working papers, partly to comply with LCDC Goals. <br />The-1978 Technical Supplement, .a product of the working papers and the various reports, - <br />prepared during preparation of the first upda -e ~ Metro Plan diagram, is available under <br />separate cover. It was written for use by those who wish more information on the technical <br />aspects of the Metro Plan and its preparation. It can also be of assistance for in-depth analysis of <br />metropolitan planning issues. <br />The working papers and Technical Supplement have been amended through. uses of individual <br />elements in Chanter III, nay ire afn~ncled in eon~un~tic~n ~~ritl~z~ bra-a~nencl~n~nt ~ro~~r to <br />' During a-major 4w-yaa+ updates., working papers and the Technical Supplement <br />are reviewed and updated as part of a comprehensive work program.

They are 44, cd <br />includeee in the Introduction because of their general application. <br />General Assumptions <br />a <br />1. A population of 286,000293; 09 is expected to reside within the metropolitan'U'GBare <br />by the year 201509. This is a 2959 percent increase from the estimated 20001 census <br />population of 222,500=1944,-"W. Since this Metro Plan is designed to accommodate the <br />expected population rather than remain static until 201500, it can be adjusted periodically <br />as changes in population trends are detected. <br />2. Based on recent trends, the rate of population growth and the rate of in-migration are <br />projected to decrease. <br />3, Ia addition to population growth, increasing household formation rates (i. e., decreasing <br />average household size) will increase the demand for housing. <br />4. In addition to population growth, increasing labor force participation rates will increase <br />the resident labor force, thereby increasing the demand for employment opportunities. <br />I-7 <br />Laurel Ridge Record (Z 15-5) Page 121 <br />
