This project develops a smartphone-based prototype system that supplements the 511 system to improve its dynamic traffic routing service to state highway users under non-recurrent congestion. This system will save considerable time to provide crucial traffic information and en-route assistance to travelers for them to avoid being trapped in traffic congestion due to accidents, work zones, hazards, or special events. It also creates a feedback loop between travelers and responsible agencies that enable the state to effectively collect, fuse, and analyze crowd-sourced data for next-gen transportation planning and management. This project can result in substantial economic savings (e.g. less traffic congestion, reduced fuel wastage and emissions) and safety benefits for the freight industry and society due to better dissemination of real-time traffic information by highway users. Such benefits will increase significantly in future with the expected increase in freight traffic on the network. The proposed system also has the flexibility to be integrated with various transportation management modules to assist state agencies to improve transportation services and daily operations.

The North Fork Maquoketa River Headwaters (NFMRH) has been identified as impaired by nutrients, episodic slugs of ammonia and sediment. The NFMRH TMDL plan calls for a "phasing approach" to managing water quality when the origin is non-point source contaminants. This project will address phase 1 using a performance reward program for targeted cooperators to improve environmental index scores using cost-share, EQIP practices and flexible management alternatives. Pre-project assessments suggest that rewards should target refined management of erosion-prone fields and farms with livestock populations, which contribute to the P and N loads responsible for fertilizing filamentous algae blooms that depress dissolved oxygen concentrations in the NFMRH. The Phosphorus Index, Soil Conditioning Index and cornstalk nitrate test will be used by producers to determine effective alternatives, such as no-till planting, to reduce nutrient and sediment delivery. These evironmental indexes will be especially useful for livestock producers in the livestock dense watershed. This project will extend a NRCS-sponsored Conservation Innovation Grant currently offered to producers in the Coffee Creek sub-watershed to a three-year, watershed-wide effort that will be necessary to make significant improvements in environmental management.

With the Saylor Creek Watershed Improvement Project, Iowa Heartland RC&D and other area stakeholders have an opportunity to display how "best management practices" (BMPs) can reduce storm water runoff and improve the quality of that runoff in an urban setting. Conservation design is a uew approach to storm water management that addresses the negative impacts of storm water runoff and turns them into a positive. The master plan for the Prairie Trail development surrounding the watershed project will incorporate bioretention cells, bioswales, buffer strips, rain gardens, as well as native plant landscaping to slow storm water runoff and naturally clean sediment out of the water before it reaches Saylor Creek. In addition to conservation design elements, the project will utilize storm water detention ponds and creek bed restoration to develop a complete storm water "treatment train" system within Prairie Trail. The extensive use of conservation storm water management for Prairie Trail is unique for urban development in Iowa.

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.

Lower Coldwater and Palmer Creeks in Butler and Floyd counties are subwatersheds of the Cedar River, which provides drinking water to Cedar Rapids, IA. The increasing concentration of nitrate+nitrate in the river is of concern to the Cedar Rapids water utility, and IDNR snapshot monitoring shows Coldwater and Palmer to be significant potential sources (above the 90th percentile for subwatersheds monitored). Both creeks are also on the Iowa Section 303(d) list of impaired waters (aquatic life). Citizens of these predominantly agricultural watersheds organized the Coldwater-Palmer Watershed Improvement Association to deal proactively with nonpoint source pollutants from crop and livestock operations through a performance-based environmental management program. The locally-adapted program implemented by the Coldwater-Palmer watershed council rewards participants for environmental accomplishments - soil quality improvement and nutrient source reduction as measured by accepted, scientifically-based tests and models. Most of the locally­appropriate BMPs used to improve performance are undertaken voluntarily at participants' initiative. WIRB funds will be combined with funding from the Iowa Com Growers Association and significant in-kind support from the Cedar River Watershed Monitoring Coalition, Iowa State University Extension and other partners. The project will result in sustainable reduction in nutrient loading achieved with voluntary participation of a majority of watershed farm operators.
