06012-006 Lime Creek NPS Project Final Report

Lime Creek is a sub-watershed of the Cedar River above; approximately 25 miles from Cedar Rapids. The lower half of the stream is on the Iowa 2004 Section 303(d) impaired waters list. Monitoring by the Cedar River Watershed Monitoring Coalition documents that Lime Creek delivers above average amounts of nitrate+ nitrite-N, ammonia-Nand total phosphorus (above the 901 percentile) compared to other Cedar River sub-watersheds. The Cedar Rapids water utility is concerned about increasing delivery of nitrate+nitrate to the Cedar River, which provides drinking water for about 125,000 people in the area. A group of local citizens has formed the Lime Creek watershed council with the goal of reducing pollutant delivery to the creek and promoting sustainable, watershed-wide action by producers, urban and rural residents for improved environmental management. The council has established a performance-based program that rewards cooperators for improvement in research-based test and index scores which directly measure environmental impact of BMPs. The Iowa Com Growers Association is funding the performance rewards. The Watershed Coalition is contributing in-kind monitoring. Council and performance cooperators participate primarily with commitment of their own resources. WIRB funds will be used to increase program cooperators and for staff support. In addition to improvement of water quality in Lime Creek, the project will establish baseline values for arket-based a pro ch to valuing pollutant reduction by intensive livestock operations in eastern Iowa.

07008-002 Yellow River Watershed Improvement Project Final Report

Two sections of the Yellow River have been named to the State of Iowa’s 303d list of impaired waters. The listing reflects streams with pollution problems linked to habitat alterations, in addition to those with potential disease causing bacteria, viruses and parasites. This fact, combined with local knowledge of water quality problems, shows the need for land treatment practices and habitat improvement measures. This project would target the Yellow River watershed, which totals approximately 49,800 acres. Areas that drain directly into the Yellow River mainstream will be targeted. Individually, these areas are too small to be considered sub-watersheds. This project will assess the drainage areas for active gullies and prioritize grade stabilization structures based upon severity and impact on the fishery. Funding would be utilized to target high priority grade stabilization structure sites and provide cost-share for those projects. A prerequisite for cost-share allocation is 75% of the land contributing to the drainage area must have some form of treatment in place. The Allamakee SWCD has received an EPA Region 7 Grant toward grade stabilization structures in the same area. Landowners have indicated that 75% cost-share is necessary to implement practices. To meet this request, the EPA funding would be used at a 15% cost-share rate if matched with 60% cost-share from WIRB funding. If matched with Federal EQIP funds, 25% of funds obtained from WIRB would be used. If other funds were depleted, WIRB funds would be utilized for the entire 75% cost-share.

05011-055 Yellow River Watershed Improvement Project Final Report

An overall effort has been initiated to improve the quality of the Yellow River in Northeast Iowa by reducing the amount of sediment and bacteria entering the stream. Funding for this project will be utilized to improve stream quality to the level of fully supporting game fish such as brown, rainbow and brook trout, walleye, northern pike and smallmouth bass. The Yellow River has the potential to be one of the top trout streams, not only in Iowa, but in the entire Upper Midwest. This project will greatly enhance recreational activities such as fishing, canoeing and inner tubing and will greatly increase tourism dollars to the state. The project will specifically address two sources of impairment: stream bank erosion and coliform bacteria from both livestock and inadequate human septic systems.

A Multi-Project Scheduling Procedure for Transportation Projects, Final Report, HR-339, 1993

This report proposes, that for certain types of highway construction projects undertaken by the Iowa Department of Transportation, a scheduling technique commonly referred to as linear scheduling may be more effective than the Critical Path Method scheduling technique that is currently being used. The types of projects that appear to be good candidates for the technique are those projects that have a strong linear orientation. Like a bar chart, this technique shows when an activity is scheduled to occur and like a CPM schedule it shows the sequence in which activities are expected to occur. During the 1992 construction season, the authors worked with an inlay project on Interstate 29 to demonstrate the linear scheduling technique to the Construction Office. The as-planned schedule was developed from the CPM schedule that the contractor had developed for the project. Therefore, this schedule represents what a linear representation of a CPM schedule would look like, and not necessarily what a true linear schedule would look like if it had been the only scheduling technique applied to the project. There is a need to expand the current repertoire of scheduling techniques to address those projects for which the bar chart and CPM may not be appropriate either because of the lack of control information or due to overly complex process for the actual project characteristics. The scheduling approaches used today on transportation projects have many shortcomings for properly modeling the real world constraints and conditions which are encountered. Linear project's predilection for activities with variable production rates, a concept very difficult to handle with the CPM, is easily handled and visualized with the linear technique. It is recommended that work proceed with the refinement of the method of linear scheduling described above and the development of a microcomputer based system for use by the Iowa Department of Transportation and contractors for its implementation. The system will be designed to provide the information needed to adjust schedules in a rational understandable method for monitoring progress on the projects and alerting Iowa Department of Transportation personnel when the contractor is deviating from the plan.

The Draft EIS, which was distributed in July 2002, is incorporated by reference herein and made a part of the Final EIS.

Rathbun Lake Special Project: BMPs for priority land in Targeted Sub-Watershed 2012 1221-010, Final Report 2013-2061,

The Rathbun Land and Water Alliance and partners have undertaken a highly effective approach to water quality protection through the Rathbun Lake Special Project. This approach is achieving a significant reduction in the sediment and phosphorus that impair water quality in Rathbun Lake and its tributaries as a result of the targeted application of best management practices (BMPs) for priority land in the watershed. This project application proposes to assist landowners to apply BMPs that will reduce sediment and phosphorus delivery from priority land in three targeted sub-watersheds as part of the Rathbun Lake Special Project. Features of this project are: (1) use of geographic information system (GIS) analysis to identify priority land that requires BMPs; (2) assistance for landowners to apply BMPs for 1,200 acres that will reduce the annual delivery of sediment by 1,800 tons and phosphorus by 6,000 pounds; (3) evaluation of the benefits from BMP application using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs for priority land to protect water quality.

Dry Run Creek Watershed Improvement Project 1248-023: Final Project Report: July 2013-December 2015, October 11, 2016

In 2010 a group of farmers in the Dry Run Creek watershed, an Iowa High Quality Water Resource, formed the Dry Run Creek Watershed Improvement Association to learn more about and implement solutions to remedy a bacteria impairment in their stream. Through a partnership with Luther College, Iowa DNR Watershed Monitoring and Assessment and Iowa State University Extension the farmers were able to conduct an assessment of their stream and watershed. The assessment showed multiple potential sources of bacteria, dependent on whether water samples were collected following rain events or during dry conditions. This project will allow watershed farmers to implement solutions to reduce bacteria delivery during both wet and dry weather. Funding will be targeted to feedlot runoff control improvements, cover crops and vegetative filters, manure management strategies and livestock stream access. The council intends to continue intensive water monitoring to determine whether the strategies are successful. Research shows the bacteria reduction in water bodies can be seen relatively quickly, within 1-2 years, compared to other types of impairments.

Lake LaVerne Watershed Project Progress Report: Project Number 1415-007, Final Report, June 30, 2016

This application targets a critical need for low maintenance and inexpensive treatment solutions to encourage landowners and resource managers to enhance the water quality of small ponds and lakes. Many rural and urban small ponds and lakes across Iowa and the region have eutrophic conditions with high levels of nutrients and low levels of oxygen. Story SWCD teamed with Iowa State University (ISU) researchers propose to address this need through the construction and monitoring of a vegetated floating island (VFI) system on ISU's iconic Lake LaVerne. VFI's are hydroponically-vegetated islands that reduce nutrient loading directly from pond and lake water (rather than from soil adjacent to the pond). Urban watershed assessment on the ISU campus has already led to reductions in stormwater runoff to the lake but eutrophic conditions persist and are well documented. The VFI will function as a public art attraction for the entire 2015 growing season during which time monitoring will occur to quantify nitrogen, phosphorus and carbon changes in the lake. Tens of thousands of visitors to the ISU campus and Lake LaVerne will interact with this installation using promotional signage on site, public events and interactive social media throughout the project. Water quality and vegetation analysis will quantify nutrient uptake by the island vegetation and thus determine its effectiveness for use in other similar water bodies in Iowa.

Determine Initial Cause for Current Premature Portland Cement Concrete Pavement Deterioration Final Report, 2000

A detailed investigation has been conducted on core samples taken from 17 portland cement concrete pavements located in Iowa. The goal of the investigation was to help to clarify the root cause of the premature deterioration problem that has become evident since the early 1990s. Laboratory experiments were also conducted to evaluate how cement composition, mixing time, and admixtures could have influenced the occurrence of premature deterioration. The cements used in this study were selected in an attempt to cover the main compositional parameters pertinent to the construction industry in Iowa. The hardened air content determinations conducted during this study indicated that the pavements that exhibited premature deterioration often contained poor to marginal entrained-air void systems. In addition, petrographic studies indicated that sometimes the entrained-air void system had been marginal after mixing and placement of the pavement slab, while in other instances a marginal to adequate entrained-air void system had been filled with ettringite. The filling was most probably accelerated because of shrinkage cracking at the surface of the concrete pavements. The results of this study suggest that the durability—more sciecifically, the frost resistance—of the concrete pavements should be less than anticipated during the design stage of the pavements. Construction practices played a significant role in the premature deterioration problem. The pavements that exhibited premature distress also exhibited features that suggested poor mixing and poor control of aggregate grading. Segregation was very common in the cores extracted from the pavements that exhibited premature distress. This suggests that the vibrators on the paver were used to overcome a workability problem. Entrained-air voids formed in concrete mixtures experiencing these types of problems normally tend to be extremely coarse, and hence they can easily be lost during the paving process. This tends to leave the pavement with a low air content and a poor distribution of air voids. All of these features were consistent with a premature stiffening problem that drastically influenced the ability of the contractor to place the concrete mixture. Laboratory studies conducted during this project indicated that most premature stiffening problems can be directly attributed to the portland cement used on the project. The admixtures (class C fly ash and water reducer) tended to have only a minor influence on the premature stiffening problem when they were used at the dosage rates described in this study.

Systematic Identification of High Crash Locations Final Report, 2001

Federal and state policy makers increasingly emphasize the need to reduce highway crash rates. This emphasis is demonstrated in Iowa’s recently released draft Iowa Strategic Highway Safety Plan and by the U.S. Department of Transportation’s placement of “improved transportation safety” at the top of its list of strategic goals. Thus, finding improved methods to enhance highway safety has become a top priority at highway agencies. The objective of this project is to develop tools and procedures by which Iowa engineers can identify potentially hazardous roadway locations and designs, and to demonstrate the utility of these tools by developing candidate lists of high crash locations in the State. An initial task, building an integrated database to facilitate the tools and procedures, is an important product, in and of itself. Accordingly, the Iowa Department of Transportation (Iowa DOT) Geographic Information Management System (GIMS) and Geographic Information System Accident Analysis and Location System (GIS-ALAS) databases were integrated with available digital imagery. (The GIMS database contains roadway characteristics, e.g., lane width, surface and shoulder type, and traffic volume, for all public roadways. GIS-ALAS records include data, e.g., vehicles, drivers, roadway conditions, and the crash severity, for crashes occurring on public roadways during then past 10 years.)

09033-018 Camp Creek Final Report

Growing Green Communities is strongly committed to improving the quality of Camp Creek and its watershed by reducing soil loss, which will benefit landowners by preserving their topsoil and improve the water quality of Camp Creek by reducing sediment loading of the creek. To accomplish the goal of reducing soil loss and improving water quality, Growing Green Communities has worked with the Iowa Department of Natural Resources to identify areas of concentrated flow paths (CFPs) within the Camp Creek Watershed using LiDAR topographic mapping technology. A goal of this project is to identify sites expected to have the greatest impact in reducing soil loss and to install Best Management Practices (BMPs) at these sites. Landowners and other project partners will work to develop the most effective BMPs for each site. After the BMPs are designed and constructed, a conservation easement will be recorded to protect the BMPs. GGC plans to record 40 acres as easements. The easements will be purchased by Growing Green Communities and donated to a qualified conservation organization for long term management and maintenance.

Iowa's Rural Alzheimer's Demonstration Project, July 1, 2004 - June 31, 2007

The Iowa Department of Elder Affairs, in collaboration with the Iowa Department of Elder Affairs (IDEA) and the University of Iowa College of Nursing (UI CON), has been engaged in developing and evaluating community based services for persons with dementia in the state of Iowa over the past 7 years under two grants form the Administration on Aging. In the current grant period, the involved agencies have completed a collaborative effort aimed to increase the capacity of Adult Day Health and Respite (ADR) providers in serving persons with dementia. Adult day services and respite care were identified by participants in the initial grant through various processes and service providers as important components of caring for persons with dementia and that there was a gap of these services in the state. Therefore, adult day and respite services were chosen as a target for the second AoA grant. The focus, in particular, was to enhance capacity to care for persons with later stages of the disease and those in rural settings as well as to begin to develop services that are more responsive to emerging minority populations. The process of the grant provided the state with a rich amount of information about the status of Iowa’s Adult Day Service providers in general and in regard to provision of dementia specific services, as well as valuable insights into the capability of rural communities to serve persons with dementia and their caregivers at home.
