Davenport, Iowa to La Crosse, Wisconsin: Highway Corridor Study, 1974

The proposed Davenport to Lacrosse route corridor includes the Iowa counties of Scott, Clinton, Jackson, and Dubuque. In addition, an influence region has been defined which includes six additional counties. The region is predominantly agricultural, however, following the national trend, movement away from the small farm to large mechanized operations has created an adequate labor force for the two major industrial cities of Davenport and Dubuque. From a total 1971 regional work force of 186,990, only 23,190, or slightly over 12% were engaged in agriculture, 91% of the land area being agricultural notwithstanding. It is forecasted that the urban population of the two counties containing the above cities will increase by 26% between 1970 and 1990, while the population of the remaining region counties can expect only a 3% increase.

Data Processing Systems Manual: Highway Noise Prediction, 1972

The Data Processing Department of ISHC has developed coding forms to be used for the data to be entered into the program. The Highway Planning and Programming and the Design Departments are responsible for coding and submitting the necessary data forms to Data Processing for the noise prediction on the highway sections.

Phase I Environmental Site Assessment of the Proposed State Highway 60 Bypass Around Le Mars, Iowa, Plymouth County, Abridged Phase I, 2001

This report serves as a record of the Assessment activities, which consisted of a review of local, county, state, and federal records, interviews, and site reconnaissance. Sections 2 through 4 of this report document information gathered. during the records search and site visits for the Assessment. Section 5 presents the findings and conclusions of the Assessment.

US Highway 65 / IA-330 Improvements Polk and Jasper Counties, Iowa : Limited Phase I, Environmental Site Assessment, 1998

The Iowa Department of Transportation (IDOT) is currently considering improvements for US Highway 65 (US-65) and Iowa State Highway 330 (IA-330) in Polk and Jasper Counties, Iowa. As part of its project planning effort, IDOT is preparing an Environmental Assessment (EA) report which will include a section entitled "Hazardous Waste" to identify known sites in or near the proposed corridors that are, or could be, contaminated with hazardous or petroleum substances.

Final Report: 1988 Iowa Department of Transportation Organizational Survey, 1988

In June 1988, 1341 employees of the Iowa State Department of Transportation (DOT) were surveyed via a mailed questionnaire. The sample was selected such that conclusions about all DOT employees, male employees, female employees, majority employees; minority employees, employees under age 40, and employees 40 years of age or older could be made. These sampling characteristics were chosen in order to facilitate comparisons between current DOT employee attitudes and employee attitudes evaluated in 1984. In addition, the sample size and response rates were sufficiently high that conclusions could be made about each of the six districts, the Ames Highway Division, and the Ames complex, excluding the Highway Division. Altogether fifty-five percent (or 739) questionnaires were· returned. Thirty additional employees voluntarily completed the survey, resulting in a final sample size of 769. The survey covered topics related to job satisfaction, work environment or climate, skill utilization, sexual harassment, communication and information adequacy, and morale. The first four topics were evaluated in 198- while the last two were unique to this survey.

Evolution of Design Practice at the Iowa State Highway Commission for the Determination of Peak Discharges at Bridges and Culverts, 1971

This paper carries the rather weighty title of "Evolution of Design Practice at the Iowa State Highway Commission for the Determination of Peak Discharges at .Bridges and Culverts." Hopefully, this evolving process will lead to a more precise definition of a peak rate of runoff for a selected recurrence interval at a particular site. In this paper the author will relate where the Highway Commission has been, is now, and will be going in this art of hydrology. He will then offer some examples at a few sites in Iowa to illustrate the use of the various methods. Finally, he will look ahead to some of the pitfalls still lying in wait for us.

Highway 60 Reconstruction Project : Final Environmental Impact Statement, 2004

The proposed reconstruction of Trunk Highway 60 is considered a Federal Class I Action because of the potential for significant impacts on the natural and physical environment. An Environmental Impact Statement (EIS) is a full disclosure document that discusses the environmental impacts of a proposed Class I action. The Draft EIS, which was distributed in July 2002, is incorporated by reference herein and made a part of the Final EIS.

Highway Location Reference Procedure Project, 1990

The purpose of the proposed Highway Location Reference Procedure is stated in the contract as follows: "Establishment of a highway network locational reference process that will primarily allow for the proper correlation of pavement management data, and secondarily provide the basis for other existing and future data base integration and for the planned Iowa DOT Geographic Information System. In addition, the locational reference process will be able to correlate network applications with a statewide spatial location method to facilitate the relationship of Iowa DOT data to that of other agencies and to allow for the graphic display of the network in map form." The Design Specifications and Implementation Plan, included in this Final Report, are intended to provide the basis for proceeding with immediate development and implementation of the pavement management system. These specifications will also support the future Iowa DOT implementation of other integrated data bases and/or the planned Geographic Information System.

Preliminary Assessment of the Potential Use of Alternative Materials for Concrete Highway Pavement Joints, 1997

The overall objective of the work contained in this paper is to identify background information on the use of load-transfer devices in highway pavement joints and to provide a preliminary assessment of the market potential for use of alternative materials in that capacity. The intent of the authors is to provide a concise compilation of information upon which HITEC personnel may judge whether or not the use of alternative materials for concrete highway pavement joints is worth a more thorough and rigorous evaluation.

U.S. Highway 20 Corridor Development Study - Report C: Final Screening of Alternative Candidate Improvements, 1992

This report briefly compares the alternative improvement options using analyses conducted to date, and is intended to identify the alternatives which should be carried forward into the study's economic evaluation phase.
