Tree and Brush Control For County Road Right-of-Way, Ocotober 2002

This manual summarizes the roadside tree and brush control methods used by all of Iowa's 99 counties. It is based on interviews conducted in Spring 2002 with county engineers, roadside managers and others. The target audience of this manual is the novice county engineer or roadside manager. Iowa law is nearly silent on roadside tree and brush control, so individual counties have been left to decide on the level of control they want to achieve and maintain. Different solutions have been developed but the goal of every county remains the same: to provide safe roads for the traveling public. Counties in eastern and southern Iowa appear to face the greatest brush control challenge. Most control efforts can be divided into two categories: mechanical and chemical. Mechanical control includes cutting tools and supporting equipment. A chain saw is the most widely used cutting tool. Tractor mounted boom mowers and brush cutters are used to prune miles of brush but have significant safety and aesthetic limitations and boom mowers are easily broken by inexperienced operators. The advent of tree shears and hydraulic thumbs offer unprecedented versatility. Bulldozers are often considered a method of last resort since they reduce large areas to bare ground. Any chipper that violently grabs brush should not be used. Chemical control is the application of herbicide to different parts of a plant: foliar spray is applied to leaves; basal bark spray is applied to the tree trunk; a cut stump treatment is applied to the cambium ring of a cut surface. There is reluctance by many to apply herbicide into the air due to drift concerns. One-third of Iowa counties do not use foliar spray. By contrast, several accepted control methods are directed toward the ground. Freshly cut stumps should be treated to prevent resprouting. Basal bark spray is highly effective in sensitive areas such as near houses. Interest in chemical control is slowly increasing as herbicides and application methods are refined. Fall burning, a third, distinctly separate technique is underused as a brush control method and can be effective if timed correctly. In all, control methods tend to reflect agricultural patterns in a county. The use of chain saws and foliar sprays tends to increase in counties where row crops predominate, and boom mowing tends to increase in counties where grassland predominates. For counties with light to moderate roadside brush, rotational maintenance is the key to effective control. The most comprehensive approach to control is to implement an integrated roadside vegetation management (IRVM) program. An IRVM program is usually directed by a Roadside Manager whose duties may be shared with another position. Funding for control programs comes from the Rural Services Basic portion of a county's budget. The average annual county brush control budget is about $76,000. That figure is thought not to include shared expenses such as fuel and buildings. Start up costs for an IRVM program are less if an existing control program is converted. In addition, IRVM budgets from three different northeastern Iowa counties are offered for comparison in this manual. The manual also includes a chapter on temporary traffic control in rural work zones, a summary of the Iowa Code as it relates to brush control, and rules on avoiding seasonal disturbance of the endangered Indiana bat. Appendices summarize survey and forest cover data, an equipment inventory, sample forms for record keeping, a sample brush control policy, a few legal opinions, a literature search, and a glossary.

Performance of Nongrouted Thin Bonded PCC Overlays, Construction Report, HR-291, 1986

The Iowa road system has approximately 13,000 miles of Portland Cement Concrete Pavements, many of which are reaching the stage where major rehabilitation is required. Age, greater than anticipated traffic, heavier loads and deterioration related to coarse aggregate in the original pavement are some of the reasons that these pavements have reached this level of distress. One method utilized to rehabilitate distressed or underdesigned PCC pavements is the thin bonded Portland Cement Concrete overlay. Since the introduction of thin bonded overlays on highway pavements in 1973, the concrete paving industry has made progress in reducing the construction costs of this rehabilitation technique. With the advent of the shotblast machine, surface preparation costs have decreased from over $4.00 per square yard to most recently $1.42 per square yard. Other construction costs, including placement, grouting and sawing, have also declined. With each project, knowledge and efficiency have improved.

Welcoming New Iowans; A Guide for Christians and Churches, 2002

Immigrant and refugee newcomers have an important role in Iowa. These newcomers have revitalized many Iowa communities, workplaces and faith-based institutions. The arrival of immigrants and refugees poses challenges as well as rewards; understanding and addressing these issues is vital to welcoming and accommodating new Iowans and assuring their part in the long-term economic and social health of our state. This handbook represents a unique collaboration between the University of Northern Iowa (UNI) and Ecumenical Ministries of Iowa (EMI). The goal of this collaboration is to create a guidebook for Iowans to learn more about Iowa’s growing immigrant and refugee population and discover ways to welcome these newcomers and accommodate them in our communities and churches. The unique nature of this joint publication between a public university and Christian churches acknowledges that both institutions have a stake in accommodating immigrants in Iowa. UNI and all institutions of higher education need to support population growth to assure future enrollments. Churches and many other community institutions need immigrants and other newcomers to help maintain their viability. Universities and churches also need healthy local economies. Newcomers can provide much needed skills and labor to make this happen. In short, His collaboration recognizes that making immigration in Iowa work has important long-term implications for us all. This book was written and compiled by two university faculty members, but it is not an official university endorsement of Christianity as the only religion practiced and accepted by Iowans, and no university funds were used to print or distribute this handbook. This handbook is written for Iowa’s Christian community and is based on the Biblical mandate to welcome newcomers, but we acknowledge Iowa’s other religious groups and their role in accommodating newcomers as well. We readily acknowledge that other faith-based organizations also welcome newcomers and have a stake in making immigration a positive experience. In order to accommodate the perspectives and needs of these groups, the UNI New Iowans Program is planning to develop similar handbooks for Iowa’s Jewish and Muslim communities. This handbook includes a number of resource lists for individuals, newcomers, churches and others. Of course, as soon as these lists are printed, they may become out-of-date. In order to obtain the most up-to-date information, please visit the UNI New Iowans Web site: www.bcs.uni.edu/idm/newiowans/ The UNI New Iowans website also makes this handbook available in a PDF format.

Developing Smooth, Quiet, Safe Portland Cement Concrete Pavements, March 2004

The concrete paving industry has spent large amounts of time working to provide safe, quiet, and smooth pavements for the traveling public as their needs and driving habits have changed since the advent of the automobile. During that time, the efforts of research, design, and construction were directed at one of the problems at a time. Current public surveys indicate that the traveling public wishes to have safe, quiet, and smooth pavements. This report identifies the problems remaining in the areas of developing smooth, quiet, and safe portland cement concrete pavement in each pavement we build. It develops the research framework that can be used to bring the existing information together with additional research in each area. The resulting answers can be used in each pavement design for a quiet, safe, and smooth pavement that is also long lasting.

Cracking and Seating to Retard Reflective Cracking - Fremont County, HR-279, 1993

The concept of cracking and seating a portland cement concrete (pcc) pavement prior to laying an asphalt cement concrete (acc) surface in order to reduce reflection cracking has been around since the 1950s. With the advent of improved cracking equipment, this method gained renewed interest in the 1970s and 1980s. This project incorporated six test sections of which four were cracked and seated prior to being overlaid. Fremont County decided to utilize only a 0.9 m (3 ft) cracking pattern based on a 30 m (100 ft) trial test section. Pavement cracking appeared to be effective in reducing primarily longitudinal reflectance cracking, but only marginally successful in the reduction of transverse reflective cracking.

Worker Education in Germany, 1970

With the end of World War II and the advent of a variety of economic recovery programs, it became apparent to scholars and practitioners alike that the quality of the labor force, both here and abroad, was a vital, although often overlooked, factor in industrial recovery and growth. As a result of this awareness, there has been a development of interest and concern in the area of comparative education. Of particular interest has been the growing body of literature dealing with various aspects of comparative training and retraining programs within business and industry and related government-sponsored activities.

Curb Removal Study, HR-76, Progress Report, 1962

Pavements constructed in Iowa during the period of the 1920's through the late 1940's were built with an integral curb. The purpose of the curb was to control drainage of water from the pavement surface in areas where runoff took place at a very rapid rate. It is for this reason that curbing is found on pavements constructed during this period. The curbing led the water flowing on the pavement surface to drainage outlets; this helped reduce erosion along the edge of the slab. The curbs have satisfactorily performed the job for which they were intended. The advent of bigger and faster vehicles has created a demand for changes in the design of pavements. Current designs provide wider driving surfaces with reduced grades which can better accommodate the wider cars and trucks. By present day design standards the narrow highways are inadequate and are being replaced or improved. The normal improvement procedure is to widen to 24 feet by providing additional driving surface at each edge of the pavement. Curbing is removed from the pavement so that the surface of the widening can be placed at the same level as that of the slab.
