Presentation about modernizing Waupaca County GIS zoning data.

9. OLD ZONING MAPS CONVERTED TO GIS

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.

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.

16. Only one zoning district for each parcel (plus wetlands)

17. Easy to manage with parcel changes. (Splits, Combinations, etc.)

18. Zoning parcels can be tied to other parcel based data for enhanced analysis.

21. COMBINING THESE IS LIKE…

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.

25. Road right-of-ways were cut out of old zoning.

27. Roads were buffered to establish development zones.

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.

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.

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.
