1 DANE COUNTY COMPREHENSIVE PLAN 5-YEAR UPDATE Comprehensive Plan Steering Committee 10/10/2013 Chapter 8: Land Use

2 Policy-Neutral Changes to Land Use Chapter Remove references to specific recommended ordinance amendments completed since Update to reflect ongoing nature of new initiatives on-line since 2007, such as TDR. Technical changes based on updated data, such as 2010 Land Use Inventory. Update to reflect revised component plans, such as Farmland Preservation Plan.

3 Policy Changes To Land Use Chapter Incorporate specific recommendations received to date (Dane County Towns Association). Incorporate additional recommendations from ZLR committee. Address emerging issues.

4 Emerging Issues Since 2007 Climate Change and Sustainability (ANCR, Land Use) Community Design (Land Use) Public Health (Community Facilities) Affordable Housing and Homelessness (Housing) Poverty (Economic Development)

5 Climate Change Projected Change in Annual Average Precipitation (Inches) From 1980 to 2090 (A2) Projected Change in Annual Average Temperature (F) From 1980 to 2090 (A2)

6 Climate Change Projected Change in Frequency of 1 Precip. Events (days/decade) from 1980 to 2090 (A2) Projected Change in Frequency of 100F Days Per Year From 1980 to 2090 (A2)

7 Climate Change More frequent, persistent and severe floods. More frequent and severe rainfall events. More frequent and severe droughts. More frequent 100-degree days. More frequent and extensive algae blooms. Shifting ecological landscapes. Ecological edge effects. Increase in invasive species. Higher summer and winter temperatures. Increase in number of freeze / thaw cycles.

8 Climate Change: Adaptation Flooding Identify, map, and prioritize potentially restorable wetlands in floodplain areas Restore prior-converted wetlands in upland areas to provide storage and filtration Mitigate storm flows and nutrient loading downstream Develop both long-term and short-term changes to community infrastructure Source: WICCI Water Resources Working Group (2011)

9 Climate Change: Adaptation Changes to lake hydrology and ecology Enhance and restore shoreline habitat Enhance infiltration in headwater areas Change planning and zoning for lakeshore development to account for changes in water levels Adjust and modify expectations and uses of lakes Source: WICCI Water Resources Working Group (2011)

10 Climate Change: Adaptation Increases in sediment and nutrient loading Resize infrastructure to accommodate increased storm flows Reverse the loss of wetlands; restore prior-converted wetlands Protect recharge and infiltration areas and riparian buffers Source: WICCI Water Resources Working Group (2011)

11 Resource Protection Corridors In all cases, when presented with any array that is not understood in its entirety, without a doubt, save all the pieces. Environmental corridors are a particularly vital pattern to protect because they are the key to regional diversity -- Phil Lewis

12 Resource Protection Corridors Environmental Corridors Inside Urban Service Areas Defined by Dane County Water Quality Plan (CARPC / WI DNR) Resource Protection Corridors Outside Urban Service Areas Defined by Dane County Comprehensive Plan (County Board)

13 Resource Protection Corridors As Currently Defined Wetlands Shoreland and wetland buffers 1% regional (a.k.a. 100-year ) floodplains Other areas identified in adopted town, city or village plans (may include slopes, farm soils or other environmental features)

14 Potential Amendments to Resource Protection Corridors Technical Updates New DNR Wisconsin Wetland Inventory maps (complete) New FEMA Flood Insurance Rate Maps (in progress) Town plan updates Policy Updates (for discussion) Public and nonprofit conservation lands 0.2% (a.k.a. 500-year ) regional floodplain Hydric soils Other categories of lands?

15 Currently Adopted

16 With Amended Floodplain, Wetland & Town Plan Data

17 Comparison of Current and with Technical Updates

18 Current Technical Updates + Public Lands

19 Current Technical Updates + Public Lands + 0.2% (500-yr) flood

20 Current Technical Updates + Public Lands + 0.2% (500-yr) flood + Hydric soils

21 Net Effect on Area Current corridors 152,779 acres Proposed corridors with Wetland and floodplain map updates 0.2% floodplains Hydric soils 182,315 acres (19.3% net increase in area)

22 Current Technical Updates + Public Lands + 0.2% (500-yr) flood + Hydric soils

23 Impacts to Landowners 32,616 landowners in unincorporated Dane County -22,341 landowners with no change / no corridors 10,275 landowners with changed corridor boundaries

24 Impacts to Landowners 10,275 landowners with changed corridor boundaries -3,271with an increase in buildable area 7,004 with a decrease in buildable area

25 Impacts to Landowners 7,004 with a decrease in buildable area -3,191 already zoned for development -2,891 already with an existing principal building - 39 zoned CO-1, RE-1 or otherwise not buildable 883 vacant and potentially available for development

26 Impacts to Landowners 883 vacant and potentially available for development -495 with reduced buildable area of 0 to 10% -185 with reduced buildable area of 10% to 25% -119 with reduced buildable area of 25% to 50% - 48 with reduced buildable area of 50% to 75% 36 with reduced buildable area of 75% to 100%

27 Impacts to Landowners Not accounted for: Density under town/county plans Development intentions of landowners

28 Potential Amendments to Resource Protection Corridors Next Steps Develop public information / education materials on impacts Present to Comprehensive Plan Steering Committee Incorporate Steering Committee recommendations into revised Comprehensive Plan Comprehensive Plan Adoption Process 30-day public notice of draft amendment Introduce to County Board for adoption ZLR Public Hearing County Board action
