CITIZENS WATER SUPPLY PROJECT BACKGROUND PAPER: A NEW AGENDA FOR PLANNING A New Agenda for Planning The planning issues of the next decade have already announced themselves. But policy-makers are not paying attention. 1. Immigration. The Nation is said to be approaching Zero Population Growth and its central cities are said to be in a period of increasing population loss. But in one critical (ánd central-city-oriented) sector, the population may be growing dramatically. Some estimates suggest that the number of illegal aliens in the United States is already more than 8 million; for the New York Metropolitan Area alone, the estimate of the U.S. Immigration and Naturalization Service was 1. million in 1975. As the gap widens between American affluence and the poverty of other parts of the World, particularly in this hemisphere, the influx of immigrants, legal and illegal, can be expected to grow. Meanwhile, the Census Bureau acknowledges that illegal aliens do not appear in its 1970 Census count or in its official estimate of undercount. And at virtaully no level of government do official projections of future population take illegal immigration, past or to come, into consideration. The result could be underdesign of vital projects and programs and underinvestment in the central cities where, historically, immigrants tend to congregate. 2. Urban Systems on Borrowed Time. America still thinks of itself as a young country. But many of its cities, and increasingly its suburbs, are old in terms of the "life expectancy" of basic urban systems. When part of the elevated West Side Highway fell to the street in New York City, it was no isolated incident -- for New York or the Country. The problem extends visibly to such systems as streets and parks and invisibly to sewerage, water mains and underground utilities. In a period of fiscal belt-tightening, moreover, under-maintenance accelerates the decay. Meanwhile, most of the planning and funding for urban physical "infrastructure" is still designed to meet new needs and create new systems. Even where attention is paid to what already exists (as, for example, in recent Federal transportation programs) the emphasis is on more intensive use, not on rehabilitation, replacement and a critical minimum of maintenance for an already badly weakened plant.
