Notes:
1
“P/C” means Provisional or Conditional Use Permit depending on the level of impacts (see SJCC 18.80.090.
3. Field Marking of Buffers and Tree Protection Zones. Prior to building permit approval, the location
of the outer extent of buffers and tree protection zoneTree Protection Zones adjacent to the area that will
be developed shall be marked in the field, and the Director may require field approval prior to the
commencement of permitted activities. Markings for buffers and tree protection zoneTree Protection
Zones shall be maintained throughout the duration of construction activities.
4. For recorded plats and binding site plans the applicant shall show the boundary of required buffers and
tree protection zoneTree Protection Zones on the face of the plat or plan.
5. Stream Crossings, Roads, and Trails in Buffers and Tree Protection Zones. The construction of new
or expanded roads, driveways, trails and associated culverts and bridges across streams, buffers and tree
protection zoneTree Protection Zones are allowed in conformance with SJCC 18.60.080 - 100 and the
following:
a. New roads and driveways may only be constructed across streams, or through buffers or tree
protection zoneTree Protection Zones, if there is no practicable alternative.
b. Bridges, culverts and crossings shall be designed according to the Washington Dept. of Fish and
Wildlife “Design of Road Culverts for Fish Passage, 2003” , the National Marine Fisheries Service
“Guidelines for Salmonid Passage at Stream Crossings, 2000”, and “Washington State Fish Passage and
Habitat Enhancement Restoration Programmatic”, National Marine Fisheries Service Tracking No. 2008-
03598, and SJCC 18.30.110.
c. When practicable, new roads, driveways, trails and walkways shall be located on existing road grades,
utility corridors or previously disturbed areas.
d. When required, permits and approvals must be obtained from appropriate state and federal agencies,
including but not limited to: Washington Department of Fish and Wildlife; Washington State Department
of Ecology; Washington State Department of Natural Resources; U.S. Army Corps of Engineers; U.S.
Coast Guard; NOAA Fisheries Service; and U.S. Fish and Wildlife Service.
e. The road, culvert or bridge shall be located and designed for the least adverse impact possible, and
shall not interfere with fish passage, the movement of water, large woody debris, gravel, or other stream
processes. Roads must cross aquatic FWHCAs and buffers at, or as close as possible to, a ninety degree
angle. Crossings shall not occur in salmonid spawning areas unless no other feasible crossing site exists.
In streams with salmonid breeding habitat, bridges, bottomless culverts or other alternatives that will
allow for fish passage are required, and bridge piers or abutments may not be placed within the stream or
stream banks unless there is no feasible alternative. The length of conventional culverts shall be the
minimum necessary.
f. The location and design of the road or driveway crossing must be evaluated by a qualified professional
to ensure that ecological processes will not be adversely affected.
g. Construction must occur during work windows and time limits established by the state and federal
agencies with jurisdiction.
