Proposed SMP Buffers and Exceptions (SJCC 18.35.030) Additional exceptions not shown in the examples Exceptions shown in the examples House (2,000 sq. ft. footprint) 30 ft. clearing around house Septic (5 X8 tank, pipes and 23 X40 drain field) Stormwater Control Swale (160 sq. ft.) Orchard/Garden (4,000 sq. ft.) 40% tree removal (every ten years) Hazard tree removal (3 various sized trees) Beach Access Stairs (5 ft. width) Trails (5 ft. width) Dock (8 ft. width) Bulkhead (10 X 100 ) Forest Practices Navigational aides or survey markers Site investigative work Stream crossings, roads 20% annual foliage removal for views Temporary wildlife watching blinds Wells Fences Reasonable use exceptions, nonconforming uses, structures and activities Shoreline modifications besides dock and bulkhead in example (ramp, railway, groin, buoy/float, ) Additional reductions due to locations of existing adjacent houses) Existing, new or expanding agriculture Aquaculture
House (1,800 sq. ft.) Buffer Exception smaller parcel House Clearing (30 ft.) Septic (tank & drainfield) Stormwater Swale Garden/Orchard (4,000 sq. ft.) Trails (5 ft. width) Tree Removal (40%/10yrs.) Outside Protective Buffers Hazard Tree Removal Stairs Bulkhead Dock Example = 0.78 acre parcel with 99 feet of waterfront Tree protection zone (110 ft.) Note: SJC Residential shoreline parcel sizes 45% <1 acre 67% <2 acres 45% <150 waterfront ft. 70% < 300 waterfront ft. Water quality buffer (100 ft.) Tree protection zone (35 ft.) shoreline
House Protective Buffer Example House Clearing (30 ft.) Septic (tank & drainfield) Stormwater Swale Garden/Orchard (4,000 sq. ft.) Trails (2-3 ft. width) Hazard Tree Removal Stairs Bulkhead Dock Example= 0.78 acre parcel with 99 feet of waterfront Tree protection zone (110 ft.) Note: SJC Residential shoreline parcel sizes 45% <1 acre 67% <2 acres 45% <150 waterfront ft. 70% < 300 waterfront ft. Water quality buffer (100 ft.) Tree protection zone (35 ft.) shoreline
House (1,800 sq. ft.) Buffer Exception larger parcel House Clearing (30 ft.) Septic (tank & drainfield) Stormwater Swale Garden/Orchard (4,000 sq. ft.) Outside Protective Buffer Trails (5 ft. width) Tree Removal (40%/10yrs.) Hazard Tree Removal Stairs Bulkhead Dock Example= 1.6 acre parcel with 300 feet of waterfront Tree protection zone (110 ft.) Note: SJC Residential shoreline parcel sizes 45% <1 acre 67% <2 acres 45% <150 waterfront ft. 70% < 300 waterfront ft. Water quality buffer (75 ft.) Tree protection zone (35 ft.)
Protect shoreline vegetation Action: Limit the amount of development in tree protection zones and water quality buffers to ensure these already limited buffers (e.g. no habitat buffers) can function. The science does not support development in buffers. As provisions already exist for items that are tied to shorelines (beach access stairs for example) all those activities that don t have to occur in the buffer shouldn t be allowed via an extensive exemption list. Thank you for your consideration.
