BMP INFORMATION
A.Constant vigilance shall be kept for the presence of protected fish species during all aspects of the
proposed action, particularly during in-water activities such as vessel movement, deployment of anchors &
spuds, pile driving, dredging, and placement of gravels and other fill.
1.The project manager shall designate an appropriate number of competent observers to survey the project
site and adjacent areas for protected species, including the presence of fish as conditions allow.
2.Visual surveys shall be made prior to the start of work each day, and prior to resumption of work following
any break of more than an hour. Periodic additional visual surveys throughout the work day are strongly
recommended.
3.All in-water work shall be done during the in-water work window for the waterbody. Where there is a
difference between the USCOE and WDFW work windows, the overlap of the two shall apply.
4.All pile driving and extraction shall be postponed or halted when obvious aggregations or schooling of fish
are observed within 50 yards of that work, and shall only begin/resume after the animals have voluntarily
departed the area.
5.When piloting vessels, vessel operators shall operate at speeds and power settings to avoid grounding
vessels, and minimize substrate scour and mobilization of bottom sediments.
B.No contamination of the marine environment shall result from project-related activities.
1.Appropriate materials to contain and clean potential spills shall be stored and readily available at the work
site and/or aboard project-related vessels.
2.The project manager and heavy equipment operators shall perform daily pre-work equipment inspections
for cleanliness and leaks. All heavy equipment operations shall be postponed or halted should a leak be
detected, and shall not proceed until the leak is repaired and the equipment is cleaned.
3.To the greatest extent practicable, utilize biodegradable oils for equipment that would be operated in or
near water.
4.Fueling of land-based vehicles and equipment shall take place at least 50 feet away from the water,
preferably over an impervious surface. Fueling of vessels shall be done at approved fueling facilities.
5.Turbidity and siltation from project-related work shall be minimized and contained through the appropriate
use of erosion control practices, effective silt containment devices, and the curtailment of work during
adverse weather and tidal/flow conditions.
6.All wastes shall be collected and contained for proper disposal at approved upland disposal sites
appropriate for the material(s).
7.When removing piles and other similarly treated wood, containment booms must fully enclose the work
area. Wood debris, oils, and any other materials released into lake waters must be collected, removed,
and properly disposed of at approved disposal sites.
8.All in- and over-water wood cutting would be limited to the minimum required to remove the subject wood
component, and all cutting work should be enclosed within floating containment booms.
9.When removing piles, no actions shall be taken that would cause adhering sediments to return to lake
waters.
10.Above-water containment shall be installed around removed piles to prevent sediment laden waters from
returning to lake waters.
11.Construction staging (including stocking of materials, etc.) will occur on the supply barge.

Notes:
1.Shrubs are show, and shall be planted, at least five feet on center. Trees are show, and shall be planted, at least ten feet to
center.
2.The property owner will implement and abide by the shoreline planting plan. The plants shall be installed before or
concurrent with the work authorized by this permit. A report, as-built drawing and photographs demonstrating the plants
have been installed or a report on the status of project construction will be submitted to the U.S. Army Corps of Engineers,
Seattle District, Regulatory Branch, within 12 months from the date of permit issuance. This reporting requirement may be
met by completing and submitting a U.S. Army Corps of Engineers approved Report for Mitigation Work Completion form.
3.The property owner will maintain and monitor the survival of installed shoreline plantings for five years after the U.S. Army
Corps of Engineers accepts the as-built report. Installed plants shall achieve 100% survival during monitoring Years 1 and 2.
Installed plants shall achieve at least 80% survival during monitoring Years 3, 4 and 5. Percent survival is based on the total
number of plants installed in accordance with the approved riparian planting plan. Individual plants that die will be replaced
with native riparian species in order to meet the survival performance standards.
4.The property owner will provide annual monitoring reports for five years (Monitoring Years 1-5). Each annual monitoring
report will include written and photographic documentation on plant mortality and replanting efforts and will document
whether the performance standards are being met. Photos will be taken from established points and used repeatedly for each
monitoring year. In addition to photos at designated points, photo documentation will include a panoramic view of the entire
planting area. Submitted photos will be formatted on standard 8 1/2 x 11" paper, dated with the date the photo was taken,
and clearly labeled with the direction from which the photo was taken. The photo location points will be identified on an
appropriate drawing. Annual shoreline planting monitoring reports will be submitted to the U.S. Army Corps of Engineers,
Seattle District, Regulatory Branch, by November 31 of each monitoring year. This reporting requirement may be met by
completing and submitting a U.S. Army Corps of Engineers approved Mitigation Planting Monitoring Report form.
