The following tables provide a detailed look at the role that culvert material and culvert diameter play in the overall cost of a culvert replacement project. Table 1 displays the cost per foot purchase price arranged by diameter size for the various culvert materials that are currently available. Table 2 displays the average additional culvert pipe material cost (increased cost to upsize minus original in-kind replacement cost) that would be incurred when upsizing a given diameter of culvert with a 50 foot length by factors of: 200%, 250% and 300%.


Urban Form In Europe And America, Pietro S. Nivola Jan 2010

Urban Form In Europe And America, Pietro S. Nivola

Brookings Scholar Lecture Series

Why do America's cities sprawl whereas European cities remain comparatively compact, and what difference do the patterns of urban development make? Pietro Nivola, a senior fellow at the Brookings Institution, addresses these questions. Nivola examines two kinds of determinants of urban form: (1) market forces, including those influenced by geography, demographics, and technological change, and (2) public policies shaping national transportation systems, tax policy, educational institutions, and more. He also discusses the implications of the different cityscapes for energy consumption.
