  • 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.
  • PROCESS IS DONE FOR EVERY TOWN THAT IS PARTICIPATING – 20 TOWNS
  • 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.
  • A lot of geoprocessing is completed to get through these steps.

    • 1. BRINGING WAUPACA COUNTY ZONING DATA INTO THE 21ST CENTURY
      Ian Grasshoff
      Jason Buck
      Waupaca County Land Information
    • 2. TIMELINE
      1967
      2003
      2007
      2011
      2010
      Old Zoning Ordinance Adopted
      Comp. Planning Started
      Comp Plans Adopted
      County Adopted New Zoning Ordinance
      Towns Adopt New Zoning
    • 3. ABOUT WAUPACA COUNTY
      • 2009 Estimated Population of 51,665
      • 4. 41,880 Tax Parcels – 30,234 in towns.
      • 5. 22 Towns, 6 Cities, and 6 Villages
      • 6. Approximately midway between Green Bay and Stevens Point
    • OLD ZONING GIS DATA
      DERIVED FROM ZONING MAPS CREATED IN LATE 1960’s.
      ORIGINAL MAPS ARE NOT PARCEL BASED.
      ORIGINAL MAPS ARE DIFFICULT TO INTERPRET.
    • 7. OLD “OFFICIAL ZONING MAPS”
    • 8. OLD “OFFICIAL ZONING MAPS”
    • 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.
    • 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.
    • 15. NEW ZONING GIS DATA
      THE GOAL
      CREATE TAX PARCEL BASED ZONING DATA
      • Based on preferred land use and existing zoning
      • 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.
      • 19. Ability to track residential density.
    • THE PROCESS
      CREATE PRELIMINARY NEW ZONING GIS DATA
      PRINT PRELIMINARY MAPS FOR TOWN REVIEW
      TOWN CHANGES INCORPORATED INTO GIS
      DATA LOADED INTO ZONING DATABASE
      RESIDENTIAL DENSITY DATA SETUP
      TOWN ADOPTS NEW ZONING
      FINAL NEW ZONING GIS DATA CREATED
      OFFICIAL ZONING MAPS ARE PRINTED
    • 20. TAX PARCELS
      PREFERRED LAND USE
      CREATE PRELIMINARY NEW ZONING GIS DATA
      NEW ZONING
      2-ACRE DNR WETLANDS
      OLD ZONING
    • 21. COMBINING THESE IS LIKE…
    • 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.
    • 24. WHY SO MANY SLIVERS AND GAPS?
      OLD ZONING GIS DATA
      • Old zoning districts didn’t match tax parcels.
      • 25. Road right-of-ways were cut out of old zoning.
      • 26. Flood plains were included in old zoning, not part of new zoning codes.
      PREFERRED LAND USE
      • 5 acre wetlands were used (2 acre used in to create preliminary data).
      • 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.
      • 30. Some preferred land use codes did not convert to new zoning.
    • HOW WE RESOLVED THE SLIVERS…
      For the first couple of towns, this process was done manually and took about 8 hours to complete, per town. There must be a better way….
      Used Access to find the zoning code with the highest percentage per tax parcel and used that code for the overall zoning on the parcel. This cut down the clean up process down to 5 clicks and about 10 minutes.
    • 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.
    • 32. THE PROCESS
      CREATE PRELIMINARY NEW ZONING GIS DATA
      PRINT PRELIMINARY MAPS FOR TOWN REVIEW
      TOWN CHANGES INCORPORATED INTO GIS
      DATA LOADED INTO ZONING DATABASE
      RESIDENTIAL DENSITY DATA SETUP
      TOWN ADOPTS NEW ZONING
      FINAL NEW ZONING GIS DATA CREATED
      OFFICIAL ZONING MAPS ARE PRINTED
    • 33. PRELIMINARY NEW ZONING MAP
    • 34. THE LAND INFO-TOWN LOOP – PART 1
      PRELIMINARY ZONING MAPS WERE CREATED FOR EACH TOWN
      • Maps usually had a list of questions that required the town’s attention.
      • 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.
      • 36. These questions usually led to a sit down meeting with the town.
    • THE LAND INFO-TOWN LOOP – PART 2
      Updates were made to GIS data
      New maps were printed and given to the town.
      Sometimes this would end the loop, other times there would be more meetings and changes.
      This is the stage of the process where it would have been nice to have a planner on staff.
    • 37. THE PROCESS
      CREATE PRELIMINARY NEW ZONING GIS DATA
      PRINT PRELIMINARY MAPS FOR TOWN REVIEW
      TOWN CHANGES INCORPORATED INTO GIS
      DATA LOADED INTO ZONING DATABASE

    • 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.
    • 40. THE PROCESS

    • 43. RESIDENTIAL DENSITY
      WHAT IS IT?
      • Practice of controlling where residential development occurs.
      • 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. Density is one of the ways a town can customize their zoning.
    • RESIDENTIAL DENSITY
      WHAT WE HAD TO DO?
      • Figure out the number of residential units on each tax parcel.
      • 46. A residential unit is defined as houses, apartments, duplexes and cabins. Basically any place that has a kitchen and a bedroom.
      • 47. Not simply a matter of looking at the assessment information to see where residential improvements were located.
    • RESIDENTIAL DENSITY
      DETERMING THE NUMBER OF RESIDENTIAL UNITS ON EACH PARCEL.
      GET DETAILED ASSESSMENT INFORMATION FROM THE LOCAL ASSESSORS
      CREATE GIS LAYER OF PARCELS THAT HAVE A RESIDENTIAL UNIT, BASED ON ASSESSORS DATA. RUN AN INITIAL CALCULATION ON ALL PARCELS WITH A RESIDENTIAL UNIT
      COMPARE THE DETAILED ASSESSOR DATA WITH THE COUNTY ASSESSMENT DATA. MAKE UPDATES TO RESIDENTIAL UNITS.
      COMPARE DETAILED DATA FROM THE ASSESSOR WITH GIS STRUCTURE POINTS. MAKE UPDATES TO RESIDENTIAL UNITS.
      RESULTING DATASET CONTAINS A LIST OF PARCELS WITH THE NUMBER OF RESIDENTIAL UNITS.
    • 48. THE PROCESS
      CREATE PRELIMINARY NEW ZONING GIS DATA

    • 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.
