1. Island County SMP Shoreline Residential Development Workshop December 5, 2011

2. Workshop Goals Are County’s shoreline rules the right rules to accomplish the purposes of the SMA and the community’s vision? What changes to the shoreline rules regarding residential development and redevelopment are needed?

3. Agenda 1. Introduction – 4.30 2. Presentation – 4.35 3. Breakout Vote – 5.10 4. Break – 5.30 5. Group Discussion - 5.45 6. Q & A – 6.15 7. Close – 6.30

4. Inventory and Characterization

5. Existing land use classification (from Island County Assessor)

6. Zoning in Island County Shorelines

7. Existing and potential parcels in Island County shorelines

8. Existing residential lots and residences per zone

9. RAIDs in Island County Shorelines 36 areas 32% of all shoreline parcels in county

10. Sandy Point RAID

11. Setbacks of existing development in RAIDs from Ordinary High Water Mark (percent of all parcels in RAIDs)

12. Effects of Residential Development Bing, 2011

13. Loss of Shoreline Vegetation Functions of Native Shoreline Vegetation ◦Filters pollutants and fine sediments, ◦Provides wildlife habitat ◦Provides food for aquatic species ◦Stabilizes soils ◦Stabilizes banks; reduce occurrences of landslides, damage to structures and threats to safety.

14. Overwater Structures Changes in Salmon Behavior – ◦Young Salmon fry avoid docks and piers moving away from the shore subject to attack by larger predators Less Food – ◦With less light, Salmon eat less ◦fewer small species that salmon eat Reduces Sea Grasses – ◦Rich feeding area for marine birds and fish, ◦shelter to species such as Dungeness crab, salmon and herring Sediment Movement - ◦Littoral drift is affected by placement of overwater structures Loss of Habitat ◦Habitat is lost or fragmented during construction

15. Current Standards

16. Existing Shoreline Regulations General Requirements: ◦Residential development not permitted seaward of OHWM ◦Runoff must not pollute adjacent waters or cause soil or beach erosion ◦Construction must not adversely impact geohydraulic processes ◦Natural vegetation between the OHWM and the top of banks and bluffs ten (10) feet or higher shall be retained

17. Example Residential Lot (R and RR) 20’ (100 ft for new lots and/or larger roadways 50’ (75 in N and C) Side Yard Setback 5’ (50 ft for new lots) Normal Appurtenance may be located in setback Home FWHCA Buffer: 75’

18. Existing Shoreline Regulations Shoreline Setbacks: ◦Appurtenances may be located within setback provided:  Do not obstruct view of shorelines from adjacent primary residences  Are not located within the native vegetation buffer

19. Existing Shoreline Regulations Shoreline Setbacks: ◦Common line setbacks may be allowed (min. 25’ or 50’ for C and N):

20. Critical Areas Wetland Buffers: ◦30 – 300 feet depending on  Land Use Intensity  Wetland Type  Wetland Function Fish and Wildlife Habitat Conservation Areas ◦75 foot buffer  Areas with which endangered, threatened, and sensitive species listed by the federal or state government have a primary association.  Streams.  Commercial and recreational shellfish beds.  Kelp and eelgrass beds.  Herring and smelt spawning areas.  State natural area preserves.  State natural resource conservation areas.  Species and habitats of local importance

21. Gap Analysis Note that SFR is a priority use ◦“…when developed in a manner consistent with the control of pollution and prevention of damage to the natural environment.” Prohibit new floating homes and houseboats? Require Public Access for multi-family development and subdivision into more than 4 lots? Subdivision must preclude the future need for shoreline stabilization

22. Shoreline Guidelines State Guidelines establish SFR as a “priority use” Construction of a SFR with normal appurtenances is exempt from SSDP Construction of a dock or pier associated with SFR is exempt from SSDP Ecology Recommended Vegetative Buffers: Development Type Buffer Width (feet from OHWM) Undeveloped with largely intact ecological functions Shorelines with extensive critical areas Shorelines within channel migration zones or floodplains 150 - 200 Rural residential development150 Small-lot residential development in highly developed areas with minimal critical areas 30 to 60
