Welcoming New Iowans: A Guide for Managers and Supervisors; The Best Practices of Iowa Employers with Immigrants and efugees in the Workplace, 2002

This guidebook has been published by the University of Northern Iowa New Iowans Program to assist employers, managers and supervisors with the unique challenges associated with hiring, training and integrating immigrant and refugee workers. Its purpose is to promote proactive engagement of newcomer workers to assure the vitality of Iowa businesses. Successful integration of immigrants and refugees in our workplaces and communities is essential to insure Iowa’s long-term economic and social health. This book provides essential information for human resource directors, trainers, supervisors and others as they meet the challenges and rewards of hiring immigrants and refugees. Of course, no guidebook can provide simple solutions to complex issues in a great variety if workplaces. This is not a “cookbook” with recipes that provide easy answers to challenges facing every company and worker. All employers are unique and approach problems differently. What works in one company might not work as well in another.

Identification of the Best Practices for Design, Construction, and Repair of Bridge Approches, 2005

Bridge approach settlement and the formation of the bump is a common problem in Iowa that draws upon considerable resources for maintenance and creates a negative perception in the minds of transportation users. This research study was undertaken to investigate bridge approach problems and develop new concepts for design, construction, and maintenance that will reduce this costly problem. As a result of the research described in this report, the following changes are suggested for implementation on a pilot test basis: • Use porous backfill behind the abutment and/or geocomposite drainage systems to improve drainage capacity and reduce erosion around the abutment. • On a pilot basis, connect the approach slab to the bridge abutment. Change the expansion joint at the bridge to a construction joint of 2 inch. Use a more effective joint sealing system at the CF joint. Change the abutment wall rebar from #5 to #7 for non-integral abutments. • For bridges with soft foundation or embankment soils, implement practices of better compaction, preloading, ground improvement, soil removal and replacement, or soil reinforcement that reduce time-dependent post construction settlements.

Erosion Control for Highway Applications, Phase I: Review and Synthesis of Literature, Final Report, TR-464, May 2002

The project described herein has led to a convenient, computer-based expert system for identifying and evaluating potentially effective erosion- and sedimentation-control measures for use in roadway construction throughout Iowa and elsewhere in the Midwest. The expert system is intended to be an accessible and efficient practical resource to aid state, county, and municipal engineers in the selection of the best management practices for preventing unwanted erosion and sedimentation at roadway construction sites, during and after construction.

Field Evaluation of Timber Preservation Treatments for Highway Applications Final Report, December 2007

Timber material repair and replacement cost for timber bridges is a considerable expense to highway agencies in Iowa, especially to county road departments. To address these needs, the objectives of this investigation was to study the field effectiveness of various treatment alternatives used on Iowa roadway projects and to determine if the current specifications and testing are adequate for providing proper wood preservation. To satisfy the research needs, the project scope involved a literature review, identification of metrics, questionnaire survey of Iowa counties, onsite inspections, and a review of current specifications and testing procedures. Based on the preservative information obtained, the following general conclusions were made: Copper naphthenate is recommended as the plant-applied preservative treatment for timber bridges. Best Management Practices should be followed to ensure quality treatment of timber materials. Bridge maintenance programs need to be developed and implemented. The Iowa Department of Transportation specifications for preservative treatment are the regulating specification for bridges constructed with state or federal funding in Iowa and are also recommended for all other bridges.

09028-014 Tributary B to Fourmile Creek Final Report

The city of Ankeny is submitting this WIRB application for development of green urban stormwater practices on city and private property in the Fourmile Creek watershed. The stormwater project proposed includes stream restoration of the SE Tributary to Fourmile Creek (Tributary B), including weirs, bank shaping, toe protection, trees, and native plantings. The project also includes the creation of a native buffer along the stream channel in the city’s Summerbrook Park, installing four native planting beds, installing a pervious surface trail, installing a series of rain gardens/biorentention cells, and installing educational signage. Polk County Soil and Water Conservation District has committed $17,000 towards the native buffer and rain garden/biorentention cell. The city of Ankeny was also awarded a $100,000 I-JOBS grant from IDNR to complete the stormwater retrofit practices. The largest component of this project is public education. Our vision for this project is to take the entire 281 acre watershed and address it as a whole. We want to make a collaborative watershed that not only addresses the water entering the stream channel through adjacent properties, but takes each individual parcel within the watershed and strives to reduce contributions to the stormwater system. The stormwater issues of concern for Tributary B include stormwater volume, sediment, and nutrients. The stream restoration, best management practices (BMP) at Summerbrook Park, and BMPs on private property should help decrease the volume of stormwater and reduce the amount of sediment and nutrients that enter Tributary B and ultimately Fourmile Creek.

Iowa Pavement Asset Management Decision-Making Framework & Pavement Treatment Selection Tool for Local Agencies, TR-651, 2015

Most local agencies in Iowa currently make their pavement treatment decisions based on their limited experience due primarily to lack of a systematic decision-making framework and a decision-aid tool. The lack of objective condition assessment data of agency pavements also contributes to this problem. This study developed a systematic pavement treatment selection framework for local agencies to assist them in selecting the most appropriate treatment and to help justify their maintenance and rehabilitation decisions. The framework is based on an extensive literature review of the various pavement treatment techniques in terms of their technical applicability and limitations, meaningful practices of neighboring states, and the results of a survey of local agencies. The treatment selection framework involves three different steps: pavement condition assessment, selection of technically feasible treatments using decision trees, and selection of the most appropriate treatment considering the return-on-investment (ROI) and other non-economic factors. An Excel-based spreadsheet tool that automates the treatment selection framework was also developed, along with a standalone user guide for the tool. The Pavement Treatment Selection Tool (PTST) for Local Agencies allows users to enter the severity and extent levels of existing distresses and then, recommends a set of technically feasible treatments. The tool also evaluates the ROI of each feasible treatment and, if necessary, it can also evaluate the non-economic value of each treatment option to help determine the most appropriate treatment for the pavement. It is expected that the framework and tool will help local agencies improve their pavement asset management practices significantly and make better economic and defensible decisions on pavement treatment selection.

05046-017 Dry Run Creek Watershed Final Report

Dry Run Creek Watershed was designated an impaired waterbody by DNR in 2002, following an assessment of the biota in the stream by DNR Biologist, Tom Wilton. Subsequent studies by IOWATER Snapshot effort in 2003, found e-coli bacteria concentrations and high nitrate readings in excess of the State of Iowa limits for recreational streams. The Dry Run Creek Watershed Improvement Project is comprised of five major components. Three components will feature demonstrations of structural best management practices (BMPs) to protect water quality in Dry Run Creek. The fourth is an educational workshop to "kick-off" the initiative and background the stakeholders of the watershed in new stormwater management strategies for water quality protection. The fifth is a monitoring program that will provide data on the effectiveness of the practices to be demonstrated. Measurable outcomes from these projects include monitoring to document the effectiveness of infiltration­ based BMPs to reduce pollutant loading in urban stormwater runoff and reducing the volume of stormwater discharged directly into Dry Run Creek via storm sewer flows. Understanding of and social acceptance of new stormwater strategies and practices will also be monitored by surveys of watershed stakeholders and compared to findings of a survey done before the start of the project.

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.

08019-011 Staff Beaver Creek Final Report

Staff and Beaver Creeks are two tributaries of the Upper Iowa River (UIR). Additional acres that drain directly into the UIR bring the size of the project area to 41,328 acres. The goal of the project is to reduce sediment loading and excess nutrients from reaching the streams which ultimately reach the UIR. Staff/Beaver Water Quality Project initially received funding as part of the FY 2005 WSPF/319 grant application cycle. Tremendous progress has been accomplished towards the original goals of the project. Due to the large number of Best Management Practices (BMPs) installed and the continued high interest for those practices, more work remains to be done. The heavy rains received in 2008 caused severe erosion and has dramatically increased interest in conservation practices. A thorough watershed assessment was completed in the fall of 2008. Data from this assessment indicates additional work is needed. The initial grant funding will be exhausted within fiscal year 2009. Therefore, the Howard Soil and Water Conservation District is seeking 3 years of funding. The District believes interest in the water quality project is at an all time high and that with an additional three years of funding, even more progress can be achieved in reducing sediment delivery and excess nutrients to these priority streams.

08018-010 Walnut Creek Final Report

In 2004 Walnut Creek was placed on the 303d list of impaired water bodies for lack of aquatic life with biological causes. Sediment from farmland as well as the stream banks was listed as the most likely stressor. In response to this listing a preliminary watershed assessment was completed by the six counties which have land in the Walnut Creek watershed. Walnut Creek flows through portions of Shelby, Pottawattamie, Montgomery, Mills, Page, and Fremont Counties before reaching its confluence with the West Nishnabotna River. The preliminary study assessed resource concerns and evaluated anticipated landowner participation levels for the six Huc 12 sub-watersheds which divide the Walnut Creek basin. These preliminary assessments revealed a priority sub-watershed which lies between US Hwy 6 and Hwy 34. A development grant was then funded by the Division of Soil Conservation to conduct a detailed assessment of this area. The detailed assessment involved an assessment of the uplands as well as the stream itself. A better understanding of the resource concerns was gained through the assessment, allowing for a comprehensive watershed plan to be developed. A variety of best management practices will be necessary for our project to be a success, many of which will be funded by other sources besides the WIRB. This grant is the first request for funding submitted by the East Pottawattamie and Montgomery SWCDs’. This grant will serve as the first critical step in building what is destined to be a true watershed success story.

08011-007 Ludlow Creek Final Report

Brief Project Summary (no greater than this space allows): This project is located in the Ludlow Creek Watershed, a 9,827 acre sub-watershed of the Yellow River. Ludlow Creek is extremely fragile and unique because it is a karst watershed, containing an estimated 1,188 sinkholes and depressions. Ludlow Creek may arguably contain more sinkholes per acre than any other watershed in Iowa. Water sampling data shows sediment delivery and E.coli as being water quality impairments in Ludlow Creek. The goals of this project are to 1) Reduce sediment delivery by 40%, 2) Reduce animal waste run-off which may include E.coli and nutrients by 40%, and 3) Reduce the water quality impact that sinkholes have on this watershed. The following Best Management Practices (BMPs) will be implemented to target Ludlow Creek's water quality impairments: no-till, terraces, grade stabilization structures, manure systems, strearnbank stabilization, pasture management, and both sinkhole and stream buffers. Our goal is to implement a combination of approximately 62 BMPs in the Ludlow Creek Watershed. These landowners will receive 75% cost-share for each one of these practices. If we receive funding from this grant, we will reach this 75% cost-share allocation by leveraging WHIP or EQIP funds when available, for most of these practices. This application has been reviewed and approved by the Allamakee County Soil and Water Conservation District Commissioners.

08008-004 Rathbun Lake Final Report

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 one targeted sub-watershed 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 on 1,450 acres that will reduce the annual delivery of sediment by 2,160 tons and phosphorus by 8,210 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.

1014-008 Walnut Creek Watershed Final Report

In 2004, Walnut Creek was placed on the 303d list of Impaired Waters due to a low biotic index (lack of aquatic life) during IDNR stream sampling events. Sediment originating from agriculture, streambank erosion, and channelization were listed as the most likely sources impacting aquatic life. In an effort to address these concerns, a preliminary study was completed of the multi-county watershed to identify priority areas. A Watershed Development & Planning Assistance Grant was then funded by the IDALS-DSC to conduct a detailed assessment of these prioritized sub-watersheds. The impending assessment of the watershed and the stream corridor revealed ample opportunities to address gully, sheet and rill erosion while addressing in-stream water velocity issues that plagued the riparian corridor. A comprehensive plan was developed comprised of a variety of best management practices to address the identified concerns. In 2009, this plan was submitted to the WIRB Board by the East Pottawattamie and Montgomery SWCDs and $489,455 was awarded to address concerns identified during watershed assessment inquiries. Despite adverse weather conditions, which has hampered conservation construction recently, this project has held fast to pre-project goals due to the fortitude of the project sponsors and the overwhelming participation by the watershed landowners. Unfortunately, state budget shortfalls are bringing project progress to a halt. As specified in the original WIRB funding request, practice funding for Year 3 was to come from the Division of Soil Conservation’s Watershed Protection Fund (WSPF). Due to Iowa’s budgetary restraints, the Walnut Creek WSPF application, which was submitted this spring, was not funded since no new applications in the state were funded. If funded again, this grant will serve as the critical step in continuing what is destined to be a true watershed success story.
