10. ISSUES WITH OLD ZONING GIS DATA – part 1 Data from old maps not very accurate – hand drawn. Original lines divided zoning districts are very thick, scaled to be about 50’ wide. Edits on the maps were done with pen and white out, leaving much room for error. Parcels, section lines, and other reference points not on original maps, making it difficult to know exactly what areas the zoning districts covered.
11. ISSUES WITH OLD ZONING GIS DATA – part 2 After conversion to GIS, zoning districts crossed over parcels, so a parcel could have more than one zoning district. Road right-of-ways were cut out of districts. Floodplains were included as a zoning district. Zoning administrator for almost 40 years just retired, one of the few people to understand the existing maps.
12. PREFERRED LAND USE MAPS Maps created through the comprehensive planning process – from 2003 – 2007. Major grassroots effort – hundreds of meetings with local planning commissions. A set of preferred land use codes was established, based on existing land use and the future preferred land uses. Preferred land use GIS data was created from existing land use data and input from planning meetings. Each towns preferred land use maps are unique.
13.
14. NEW ZONING GIS DATA Old zoning ordinance was changed because of the comprehensive planning effort; adopted in May 2010. New base zoning districts were adapted from the preferred land use map codes. Preferred land use translated to new zoning districts. Old zoning districts were converted to the new zoning codes. 20 out of 22 township are adopting or have adopted the new zoning. Towns can customize their zoning based on their preferred land use, using overlays, clustering, and density, so each town’s zoning is UNIQUE.
22. CREATING PRELIMINARY NEW ZONING GIS DATA PART 1 - DETERMINE GREATEST PERCENTAGE OF A ZONING CODE ON A TAX PARCEL CONVERT OLD ZONING DISTRICTS TO NEW ZONING DISTRICTS PREPARE PREFERRED LAND USE DATA PREPARE DNR 2 ACRE WETLANDS DATA PREPARE TAX PARCELS DATA INTEGRATING PREFERRED LAND USE AND NEW WETLAND DATA INTEGRATING TAX PARCELS WITH DATA FROM PREVIOUS PROCESS RESULTING DATASET CONTAINED A LOT OF SLIVERS AND GAPS
23. ALL THE BLACK ARE SLIVERS AND GAPS * IN JUST ONE TOWN – THERE WERE 524 SLIVERS TO FIX.
28. Wetlands and other land uses were buffered to establish barrier regions between land uses.
29. Tax parcels were used in creating the land use areas, not always accurately.
30.
31. …AND THE GAPS. More of a manual process than the slivers. We often had to look at the old zoning to figure out what code to use. Gaps usually were caused by the 5 acre and 2 acre wetland difference or preferred land use codes that did not transfer to new zoning. Lastly, we integrated the old zoning data (except general agriculture) so towns can see areas that need to be fixed.

35. Other questions from the town’s would often arise from these maps, including how certain parcels should be zoned, if the zoning could be changed, etc.

39. FINAL NEW ZONING DATA CREATION Basically ran the same set of processes as the preliminary data Had to update the tax parcels to be current as of day town adopted zoning. Most of the manual clean-up was done during the preliminary stage. Used models to run the processes. Much quicker than the preliminary data creation.

44. It is the number of residential units allowed in a given area, depending on lot size and zoning. For example, Ag-Woodland transition (AWT) zoning allows for 1 residential unit for every 2 acres.
45.
46. A residential unit is defined as houses, apartments, duplexes and cabins. Basically any place that has a kitchen and a bedroom.

49. THE END OF THE ROAD One more model to run, a simple export to a text file, email the file to our IS Department and the new zoning GIS data is complete and so is this presentation.
Briefly state why this project is happening. Because of the comp planning effort, the county created a new zoning ordinance, with completely new zoning codes, regulations, etc. Our job was to convert the old / existing zoning GIS data into new zoning GIS data. This talk will go into how we accomplished this task.
-Mix of farmland, forests, small cities and villages. Diverse landscape.Some development pressure due to proximity to Fox Valley.
Talk about Jeff’s goat story with the property owner who had General AG and Residential zoning on his parcel.
1.Some of the preferred land use codes, especially the mixed use ones (Rural Commercial Industrial (RCI), (Rural Crossroads-Mixed Use RCM), were not carried over.
PROCESS IS DONE FOR EVERY TOWN THAT IS PARTICIPATING – 20 TOWNS11 page document detailing steps to convert the data.
SLIVERS!!
A lot of geoprocessing is completed to get through these steps.
AT LEAST 40 STEPS, MOSTLY GEOPROCESSING, BUT SOME MANUALLY EDITING TO GET ONE TOWNS PRELIMINARY DATA COMPLETE.
Mention also the final steps of reincorporating the non-agricultural old zoning codes. This was done because the old zoning district were not based on parcels, more general areas, so when these areas were brought back in, it forced the towns to decide which codes they wanted to use.

List of zoning questions for towns to figure out.
We were usually pressed by the zoning office and the town the get the new data and maps done quickly.Talk about why we used models for the final processing but not initial.
