The Value of the County Engineer: Strategies to Expand the Shrinking Employment Pool, HR-338, 1993

The first phase of this research involved an effort to identify the issues relevant to gaining a better understanding of the County Engineering profession. A related objective was to develop strategies to attract responsible, motivated and committed professionals to pursue County Engineering positions. In an era where a large percentage of County Engineers are reaching retirement age, the shrinking employment pool may eventually jeopardize the quality of secondary road systems not only in Iowa, but nationwide. As we move toward the 21st century, in an era of declining resources, it is likely that professional staff members in charge of secondary roads will find themselves working with less flexible budgets for the construction and maintenance of roads and bridges. It was important to understand the challenges presented to them, and the degree to which those challenges will demand greater expertise in prioritizing resource allocations for the rehabilitation and maintenance of the 10 million miles of county roads nationwide. Only after understanding what a county engineer is and what this person does will it become feasible for the profession to begin "selling itself", i.e., attracting a new generation of County Engineers. Reaching this objective involved examining the responsibilities, goals, and, sometimes, the frustrations experienced by those persons in charge of secondary road systems in the nine states that agreed to participate in the study. The second phase of this research involved addressing ways to counter the problems associated with the exodus of County Engineers who are reaching retirement age. Many of the questions asked of participants asked them to compare the advantages and disadvantages of public sector work with the private sector. Based on interviews with nearly 50 County Engineers and feedback from 268 who returned surveys for the research, issues relevant to the profession were analyzed and recommendations were made to the profession as it prepares to attract a new generation. It was concluded that both State and Regional Associations for County Engineers, and the National Association of County Engineers are most well-situated to present opportunities for continued professional development. This factor is appealing for those who are interested in competitive advantages as professionals. While salaries in the public sector may not be able to effectively compete with those offered by the private sector, it was concluded that this is only one factor of concern to those who are in the business of "public service". It was concluded, however, that Boards of Supervisors and their equivalents in other states will need to more clearly understand the value of the contributions made by County Engineers. Then the selling points the profession can hope to capitalize on can focus on the strength of state organizations and a strong national organization that act as clearinghouses of information and advocates for the profession, as well as anchors that provide opportunities for staying current on issues and technologies.

Liability and Traffic Control Considerations for Low Water Stream Crossings, HR-218, 1981

The current shortage of highway funds precludes the immediate replacement of most of the bridges that have been evaluated as structurally deficient or functionally obsolete or both. A low water stream crossing (LWSC) affords an economical alternative to the replacement of a bridge with another bridge in many instances. However, the potential liability that might be incurred from the use of LWSCs has served as a deterrent to their use. Nor have guidelines for traffic control devices been developed for specific application to LWSCs. This research addressed the problems of liability and traffic control associated with the use of LWSCs. Input to the findings from this research was provided by several persons contacted by telephone plus 189 persons who responded to a questionnaire concerning their experience with LWSCs. It was concluded from this research that a significant potential for accidents and liability claims could result from the use of LWSCs. However, it was also concluded that this liability could be reduced to within acceptable limits if adequate warning of the presence of an LWSC were afforded to road users. The potential for accidents and liability could further be reduced if vehicular passage over an LWSC were precluded during periods when the road was flooded. Under these conditions, it is believed, the potential for liability from the use of an LWSC on an unpaved, rural road would be even less than that resulting from the continuing use of an inadequate bridge. The signs recommended for use in advance of an LWSC include two warning signs and one regulatory sign with legends as follows: FLOOD AREA AHEAD, IMPASSABLE DURING HIGH WATER, DO NOT ENTER WHEN FLOODED. Use of the regulatory sign would require an appropriate resolution by the Board of Supervisors having responsibility for a county road. Other recommendations include the optional use of either a supple mental distance advisory plate or an advisory speed plate, or both, under circumstances where these may be needed. It was also recommended HR-218 Liability & Traffic Control Considerations for Low Water Stream Crossings that LWSCs be used only on unpaved roads and that they not be used in locations where flooding of an LWSC would deprive dwelling places of emergency ground access.

The Local Rural Road System: Alternative Investment Strategies, HR-242, 1989

A benefit-cost analysis was used to examine the effects of alternative investment strategies on the local rural road system. The study first estimated the change in costs to the traveling public of various investment strategies, then compared the change for each investment strategy to the cost of implementing that strategy on the county rural road system. The basic purpose of this study was to develop guidelines for local supervisors and engineers in evaluating investment or disinvestment proposals, and to provide information to state legislatures in developing local rural road and bridge policies. Three case study areas of 100 sq mi each were selected in Iowa. A questionnaire was used to collect data from farm and non-farm residents in the study areas. Data were obtained on the number of 1982 trips by origin, destination, and type of vehicle.

Local Public Health Guidebook, September 2011

The local board of health is described in law in Iowa Code Chapter 137. It is described in rule in Iowa Administrative Code chapter 641.77. Law and rule define the structure, powers, and duties of the local board of health. The following information is a summation of the two. LOCAL BOARD OF HEALTH JURISDICTION AND APPOINTMENT: There are three types of local boards of health. 1. City (has to have been in existence before July 1, 2010) 2. County 3. District • City boards of health have jurisdiction over public health matters within the city. City board members are appointed by the city council. • County boards of health have jurisdiction over public health matters within the county. County board members are appointed by the county board of supervisors. • District boards of health have jurisdiction over public health matters within the district. District board of health members are appointed by the county boards of supervisors from the counties represented by the district.

Issue review : executive branch employees, January 2011 and August 2012.

This issue review examines the change in the number of executive branch employees, supervisors and payroll between January 2011 and August 2012. In recent years, a variety of factors have encouraged a reduction in the number of state employees, salary adjustment that pays for contract-related salary and benefits increases has not been funded, limited departments' ability to pay increasing personnel costs. Early retirement packages have been offered, encouraging higher-paid employees to retire. Beginning in January 2011, the Governor set a goal of reducing the cost of state government by 15 percent, which could impact the number of employees.

Effect of Video Camera-Based Remote Roadway Condition Monitoring on Snow Removal-Related Maintenance Operations. 2014

Remote monitoring through the use of cameras is widely utilized for traffic operation, but has not been utilized widely for roadway maintenance operations. The Utah Department of Transportation (UDOT) has implemented a new remote monitoring system, referred to as a Cloud-enabled Remote Video Streaming (CRVS) camera system for snow removal-related maintenance operations in the winter. The purpose of this study was to evaluate the effectiveness of the use of the CRVS camera system in snow removal-related maintenance operations. This study was conducted in two parts: opinion surveys of maintenance station supervisors and an analysis on snow removal-related maintenance costs. The responses to the opinion surveys mostly displayed positive reviews of the use of the CRVS cameras. On a scale of 1 (least effective) to 5 (most effective), the average overall effectiveness given by the station supervisors was 4.3. An expedition trip for this study was defined as a trip that was made to just check the roadways if snow-removal was necessary. The average of the responses received from surveys was calculated to be a 33 percent reduction in expedition trips. For the second part of this study, an analysis was performed on the snow removal-related maintenance cost data provided by UDOT to see if the installation of a CRVS camera had an effect in reducing expedition trips. This expedition cost comparison was performed for 10 sets of maintenance stations within Utah. It was difficult to make any definitive inferences from the comparison of expedition costs over the years for which precipitation and expedition cost data were available; hence a statistical analysis was performed using the Mixed Model ANOVA. This analysis resulted in an average of 14 percent higher ratio of expedition costs at maintenance stations with a CRVS camera before the installation of the camera compared to the ratio of expedition costs after the installation of the camera. This difference was not proven to be statistically significant at the 95 percent confident level, but indicated that the installation of CRVS cameras was on the average helpful in reducing expedition costs and may be considered practically significant. It is recommended that more detailed and consistent maintenance cost records be prepared for accurate analysis of cost records for this type of study in the future.

Iowa Drainage Laws (Annotated), HR-46 and Iowa Highway Research Board Bulletin No. 6, 1957

In the preparation of this compilation of drainage laws of Iowa, an attempt has been made to include those sections of the Code to which reference is frequently required by the State Highway Commission, Boards of Supervisors and County Engineers in the conduct of highway and road administration as it is affected by the Iowa drainage laws.

1109-003 Coe Creek Watershed Final Report

The city of Elliott has had an increase in nitrate levels in their community water supply located in the Coe Creek Watershed. They have been working with the IDNR Source Water Protection (SWP) Programs to conduct site investigations and have formed a SWP Planning Team. This Team has been reviewing the investigation findings, formed an action plan and studied different Best Management Practices (BMPs). After considering the BMPs the SWP Team made a recommendation to the Elliott City Council which included native grass seeding and a shallow water wetland. The Team also held an informational meeting for the citizens of Elliott. The goal of this meeting was to inform and educate the public of the Team findings and BMPs. The Elliott City Council approved the restoration of a shallow wetland with a native grass buffer. This whole project is 27 acres and includes a shallow water wetland with native grass buffer. This would be a long term method to reduce nitrates in the city wells. Elliott is partnering with the Natural Resources Conservation Service, Montgomery County Soil and Water Conservation District, Pheasants Forever, the Montgomery County Conservation Board, US Fish and Wildlife Service and the Montgomery County Board of Supervisors in the restoration of the shallow water wetland and native grass buffer.

05044-016 Upper Miller Creek Watershed Final Report

A water quality resource concern has come to the forefront in the Upper Miller Creek watershed in Black Hawk County after five to seven inches of rain fell on the area on May 22nd and 23rd of 2004 and unprecedented amounts of soil and organic debris were washed from cultivated areas, clogging most culverts and roadside ditches. The quantity of soil deposited in ditches gave a good indication of the amounts that were transported into the stream. The estimated total cost to Black Hawk County for cleanup and repair within the road right-of-way was $345,000. There were undetermined environmental costs incurred when the incredibly high volumes of soil washed from the fields into Miller Creek which flows directly into the Cedar River that is identified by the Department of Natural Resources as an impaired water body. The Upper Miller Creek Watershed Project is an innovative, collaborative project intended to meet a specific need identified by a local steering committee made up of concerned community agencies and local landowners. Led by the Soil and Water Conservation District and the Black Hawk County Board of Supervisors, the Miller Creek Watershed Project seeks to reduce soil erosion, improve water quality, and reduce county road infrastructure cost by implementing conservation practices, reducing nutrient and pesticide use and improving wildlife habitat.

07032-012 Lake MacBride Watershed Final Report

Lake Macbride is considered to be one of the top four lakes for fishing in the state of Iowa. It is widely used by the public and contributes significant economic benefits to the county. Lake Macbride is situated in the North Corridor which is one of the fastest growing areas in the state. The lake has a surface area of 940 acres and drains 16,205 acres. Lake Macbride is on the Iowa 303(d) list for excessive sediments and nutrients. In 2001, Lake Macbride State Park received over 2.5 million dollars from the Marine Fuel Tax and Fish and Wildlife Trust to install 2 silt basins and stabilize over 12 miles of shoreline in the lake. Also in 2001, the Johnson County SWCD received a WSPF allocation from DSC to address agriculture and urban runoff issues in the watershed. Section 319 funding was received in 2002 to continue watershed efforts to the present. A watershed assessment was completed in 2003 to guide watershed activities. In 2005, a TMDL was completed for the lake. Since 2001, over $645,000 dollars has been spent by landowners and funding partners to install conservation practices in the watershed. Watershed efforts have resulted in the reduction of over 4200 tons of soils from being delivered into Lake Macbride. Nutrient reductions have also occurred from the development of nutrient management plans on 2000 acres. The District is in the process of wrapping up watershed efforts on private land. A series of 13 structures is planned to be installed in the State Park over the next several years. One of the last remaining items that still needs addressed is 1,400 feet of eroding shoreline adjacent to Lake Macbride along Cottage Reserve Road. The road is under the jurisdiction of the Johnson County Board of Supervisors. Both the Board of Supervisors and the IDNR are willing to contribute substantial dollars to address the 250 tons of soil that are being directly delivered to Lake Macbride each year.

05008-004 Mill-Picayune (Manteno Lake) Watershed Final Report

Manteno Lake is located 8 miles northwest of Earling, IA in Shelby County. The lake has been impaired with an overload of silt and nutrients. In October of 2007, land directly north of the lake will be coming out of CRP and back into agricultural production. The Shelby Soil and Water Conservation District, Shelby County Board of Supervisors and Shelby County Conservation Board feel strongly that treatment of this area is necessary prior to the CRP contract expiring. The placement and construction of three structures will reduce the amount of silt and nutrients affecting Manteno Lake. This project calls for the construction of three structures on crucial tributaries to the lake.

Temporary Traffic Control Handbook, TR-694, 2016

This handbook provides a broad, easy to understand reference for temporary traffic control in work zones, addressing the safe and efficient accommodation of all road users: motorists, bicyclists, pedestrians, and those with special needs. When impacting a pedestrian facility, provide ten calendar days advance notification to the local jurisdiction and the National Federation of the Blind of Iowa (www.nfbi.org). The information presented is based on standards and guidance in the 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD). References to the MUTCD sign designations in this handbook are shown in parentheses, e.g. (W20-1). Not all the recommendations in this handbook will apply to every circumstance faced by local agencies, and each unique situation may not be addressed. Modifications of the typical applications in this handbook will be required to adapt to specific field conditions. Therefore, use engineering judgment, seeking the advice of experienced professionals and supervisors in difficult and complex interpretations. This handbook can be used as a reference for temporary traffic control in work zones on all city or county roadways.
