THE SOCIAL IMPACT OF TRANSPORTATION IN URBAN REGIONS: THE CASE OF THE UNIVERSITY AVENUE STREET WIDENING
PATRICK C. WEST
Environmental impact statements (EIS) on transportation projects far outnumber any other type of project impact statement (Enk 1973), and the most important impacts of transportation projects in urban regions are social impacts. The con- sideration of social impacts of urban transportation developments is one of the more important areas for the application of sociology to environmental impact assessment.
This article analyzes the social impact and community response to one common type of urban transportation project, street widening. Growth in population and motorized travel in urban areas place intolerable stress on old street and road networks. However, human settlement and social organization that have grown up organically around the vital arteries and veins of urban life are threatened by the attempts of highway engineers to "operate" on the circulation system.
In this article, a typical street widening in a small urbanized area (Green Bay, Wisconsin) illustrates these strains and the potential use of sociological theory and methods to analyze social impact and community response. The term so- ciological is defined here to mean the analysis of patterns and dynamics of social organization and interaction within human communities. Of particular concern will be sociological analyses of processes relevant to such projects in lower social strata areas. Because of these social processes operating in such areas, neither direct survey results nor community pressure are adequate to bring social impact considerations into the decision-making process. Improved sociological analysis can highlight such discrepancies, but only changes in the legal structure can force implementation of enlightened decision making.

The Study Community Green Bay and its surrounding communities comprise a small but rapidly growing urbanized area. It is located at the southern tip of Green Bay and forms a major industrial and transportation center in northeast Wisconsin. The work force is drawn from the hinterland of predominantly East European Catholic farming communities. Community social organization tends to be traditional, locally oriented, and stable with tight local community bonds.
As Green Bay grew, its old networks of narrow streets and two-lane arteries laid down in earlier years were selectively widened to accommodate the increased traffic flow. The arteries widened first became the central lines of commercial strip development. More recently, a widened street, Mason Street, was saved from this fate when the city planning commission prevented conversion to strip development through zoning laws. Even so, the predominantly elderly and blue collar residents of the street now huddle in the back of their run-down rental houses and wonder what was gained as the trucks and motorcycles rumble by. The Mason Street project had its social impact ritual, but since no state or federal monies were involved there were no formal assessment requirements and little was done to consider social impact seriously. The next comparable project, the planned widening of University Avenue, held the promise of a more rational decision process because both federal and state EIS requirements were involved (Fig. 1).
The University Avenue Widening Project University Avenue is one of two continuous arterial routes that connect the center of the city to the eastern city limits. It is a major truck route and connects commercial, residential, and industrial land uses along the route. Traffic pro- jections show increasing pressures on this major artery. The street is below standards in terms of road conditions and width, and accident rates are high, especially at key intersections.
The proposed widening was planned in four phases at different sections along the route, to be completed over a three-year period. A class in Environmental Impact Analysis taught by the author was informally engaged to conduct a social impact study of the proposed widening. The official impact statement was pre- pared by an engineering consultant firm. A citizens' advisory committee was formed early in the planning process to advise the public works department. However, this functioned mainly as an instrument of formal co-optation (Selznik 1966) to transmit proposals and seek legitimacy rather than as a mechanism for sharing actual decision-making power. Broader citizen participation was per- mitted only after the development of the draft impact statement.

Social Profile of the Community Impact Zone Prior to the Widening In considering the social preconditions of a project and its social impact, it is first important to consider the relevant social boundaries of the affected com- munity. Some have posited the use of community identification through social network analysis and determination of common cultures (Hendricks and Vlachos n.d.). Others have operated more pragmatically to determine the boundaries of probable "impact zones" surrounding a project (Appleyard and Carp 1974). The class adopted the second mode of boundary determination for the bulk of its analysis, but the wider community network boundaries also played a role in determining social constraints on community response. The immediate impact zone was defined as all sides of blocks immediately adjacent to University Avenue, and all sides of all blocks adjacent to streets being considered as al- ternative routes.
Block census data were used to determine the social profile of persons within the alternative impact zones. Social profile dimensions included:
(1) the number of people, (2) the number and percent of people that were:
(a) less than 18 years old (b) over the age of 62,
(3) the number and percent of owner-occupied houses, (4) the number and percent of renter-occupied houses, and (5) the average value of owner-occupied houses.
The social profile analysis (Table 1) reveals that the proposed corridor would have the lowest total number of people affected, the lowest percentage of people in the "less than 18 years old" age bracket, the lowest number of owner-occupied homes, and the lowest average home value. Housing values in general indicate that, for the most part, the entire area of the city is primarily a low-income neighborhood.
Social profile data were also gathered from a social survey of a random sample of residents from the impact zone along the main route. These data show that most persons are long-time residents (Table 2), that occupational levels tend to be low (Table 3), and that a great deal of social neighboring occurs (Table 4).
Behavioral observations were also made on preproject social patterns of pe- destrian behavior along this street. The main characteristics observed were bi- cycles and pedestrian traffic, children's play patterns, and street crossings. A team of observers recorded frequency and location of use on observation sched- ules at sample times and locations along the route over a three-month period. A total of 72 hours and 3,190 persons were systematically observed. The data on play patterns is a good example of the use of observation in establishing the social preconditions of a project.

impacts would be greatest were found in two areas, from Clay Street to St. George Street and from St. George Street to Irwin Street. That finding was strengthened by comparing it with census data that showed that these two sites have the largest proportion of children along the route. From this data, which shows a marked spatial variation in pedestrian use, suggestions were made for mitigating measures to minimize social impacts of the widening.
