For the construction of an irrigation district, geotechnical conditions existing soils in municipality Ponedera (Atlántico, Colombia) were analyzed, by means manual sampling and standard permeability test (SPT). This information was processed a database for analysis. The soil types obtained, most which classified as inorganic clays silts (CL ML), to lesser extent, silty clayey sands (SM SC), ma...

Many local governments are adopting inclusionary zoning (IZ) as a means of producing affordable housing without direct public subsidies. In this paper, panel data on IZ in the San Francisco metropolitan area and suburban Boston are used to analyse how much affordable housing the programmes produce and how IZ affects the prices and production of market-rate housing. The amount of affordable hous...

INTRODUCTION Zoning ordinances and land-use plans may influence the community food environment by determining placement and access to food outlets, which subsequently support or hinder residents' attempts to eat healthfully. The objective of this study was to examine associations between healthful food zoning scores as derived from information on local zoning ordinances, county demographics, an...

Alternative land use zoning scenarios provide guidance for sustainable land use controls. This study focused on an ecologically vulnerable catchment on the Loess Plateau in China, proposed a novel land use zoning model, and generated alternative zoning solutions to satisfy the various requirements of land use stakeholders and managers. This model combined multiple zoning objectives, i.e., maxim...

The products of the Information Age give geotechnical engineers powerful tools to perform their work. One view of geotechnical engineering is that Information Technology (IT) tools may replace many of the functions that geotechnical engineers now perform. This view can be framed to argue that the right IT tools will even replace the need for engineering judgment. Since geotechnical engineers re...

BACKGROUND Communities across the United States have been reforming their zoning codes to create pedestrian-friendly neighborhoods with increased street connectivity, mixed use and higher density, open space, transportation infrastructure, and a traditional neighborhood structure. Zoning code reforms include new urbanist zoning such as the SmartCode, form-based codes, transects, transportation ...

Geotechnical instruments are used widely as a complementary tool to geodetic methods in monitoring natural and man-made structures. This paper provides an overview of geotechnical instruments used in structural monitoring. The transducers commonly used in geotechnical instrumentation are first introduced. This is followed by an introduction of the various types of instruments including their wo...

We argue that anti-density zoning increases black residential segregation in U.S. metropolitan areas by reducing the quantity of affordable housing in white jurisdictions. Drawing on census data and local regulation indicators compiled by Pendall, we estimate a series of regression models to measure the effect of maximum density zoning on black segregation. Results estimated using ordinary leas...
