Shoreland Zoning14.6.0 Building Setbacks1968 Law allowed reduced setback from required 75’ setback using existing principal structures within 200’ of requesting lot

2012 Law allows reduced setback from required 75’ setback using existing principal structures within 250’ of rquesting lot

Shoreland Zoning14.7.0 Vegetation1968 Law• First 35’ no clear-cut

zone• No definition for

clear-cut

New Law • First 35’ no vegetation

removal (2015 compliance, all riparian lands)

• Access/viewing corridors• Shoreline restoration

activities & invasive species control

• Dead, dying or diseased; replaced with native vegetation

Shoreland Zoning• Help clarity by holding

sediment in place.• Take up nutrients that would

be used by algae. • Shelter for wildlife.• Wildlife food and nesting

areas.• Can help reduce erosion and

runoff. • Spawning beds in sedges

/emergent plants for fish.

90% of all lake life is born, raised and fed in the area where land and water meet.

Mitigation methods

Shoreland Zoning14.9.0 Impervious Surface Standards• Keep what you have• Up to 15% impervious no permit is needed• Between 15%-30% needs a permit and mitigation

Impervious Surface Example

15% of 20,000 sq. ft. lot

1500 sq. ft. house footprint740 sq. ft. garage

660 sq. ft. driveway100 sq. ft. sidewalk

3000 sq. ft. total

Shoreland Zoning14.11.0 Nonconforming Uses/Structures• Nonconforming structure is an existing structure that was

lawfully placed when constructed but that does not comply with the required water setback (legal, pre-existing structures)

• NR 115 provides increased flexibility for nonconforming structures in exchange for mitigation:• Vertical expansion• Horizontal and/or vertical expansion beyond the shoreline

setback• Replacement or relocation• Requires mitigation plan approved by County

• Current legislation may be changing in future regarding nonconforming structures

Shoreland Zoning

• Buffer restoration• Rain gardens• Retention/detension

basins• Eave troughs, french

drains• Removal or relocation of

legal pre-existing accessory buildings

• Elimination or reduction of Impervious surfaces

• Any other mitigation deemed appropriate by Zoning Adm. or Land Conservation

14.12.0 Mitigation

Shoreland Zoning• Healthy, natural shorelands provide lakes and rivers with high

water quality, good fishing, and higher property values

• 30+ counties revised their shoreland ordinances to more effectively protect lakes and rivers from 1995-2005

• Counties need to revise their shoreland ordinances to comply

with NR 115 by 2014

• 40+ counties have started revising their shoreland ordinances to comply with NR 115

• Assistance is available through County staff, UW-Extension, and DNR staff
