Neighborhood Area Studies were undertaken in 36 areas of Jefferson County by MSD’s Stormwater Planning Department to assess drainage problems and complaints, and to determine proposed solutions. Each of the neighborhood’s drainage systems were mapped by interns and data was collected and entered into a database. ArcView themes were developed, and various types of output designed for use in public meetings and as field mapping for detailed follow up work. The manuscript maps produced by the interns will provide detailed source documents for the drainage facilities conversion project soon to get underway.
Federal KPDES Permitting Requirements for Louisville and Jefferson County are being met utilizing the LOJIC GIS. The GIS has proven to be a useful tool in mapping and tracking pollution within watersheds. In utilizing this approach, MSD has begun an innovative management process for improving water quality in all areas of the county. Data from several different databases was combined in the GIS to locate permitted industries and discharge locations. In addition, teams of high school students work every summer on monitoring all combined sewer outfall points. MSD submits a permit application each year to the state that summarizes data collection, monitoring activities, and improvements to water quality within the watershed.
Cornerstone 2020 is a large scale, community-based effort aimed at revising Jefferson County’s Comprehensive Plan. The overall project is made up of twenty working groups that are making recommendations for different aspects of community development. The Greenways Committee used the GIS extensively to help understand the inter-relationships between land use, soil erosion, development, and natural resources. Their work has resulted in new ordinances directed at controlling development in high risk areas, and enforcing buffer zones around sensitive stream corridors.
System and network integration has become a focal priority of LOJIC users and technical staff. This last year, LOJIC successfully established data exchange procedures with the City of Louisville Office of Information Systems and the Property Valuation Administrator’s Office. These protocols and procedures result in the nightly or weekly exchange of critical data from mainframe systems to the GIS. In addition, prompted by the sewer facilities conversion project, there now exists a seamless and dynamic connection between LOJIC and the Metropolitan Sewer District’s Oracle server that manages the Hansen Infrastructure Management System, the Industrial Waste Information System and the TRIMCO Imaging System.
Metadata or Data Help and system documentation are available online in PDF format to all LOJIC users. This documentation is patterned after the National Spatial Data Standard, and provides consistent and highly detailed information about the standards and database design used to create and maintain each dataset, as well as who to contact for additional information. The documentation provides a summary of the dataset, the data template, and has hypertext links to sample graphics for a visual example.
