other measures shall be used to prevent movement of soil into waterways and
wetlands.
c. To prevent erosion, use of compost berms, impervious materials or other equally
effective methods, shall be used to protect soil stockpiled during rain events or when the
stockpile site is not moved or reshaped for more than 48 hours.
d. Unless part of the authorized permanent fill, all construction access points through, and
staging areas in, riparian and wetland areas shall use removable pads or mats to
prevent soil compaction. However, in some wetland areas under dry summer
conditions, this requirement may be waived upon approval by DSL. At project
completion, disturbed areas with soil exposed by construction activities shall be
stabilized by mulching and native vegetative plantings /seeding. Sterile grass may be
used instead of native vegetation for temporary sediment control. If soils are to remain
exposed more than seven days after completion of the permitted work, they shall be
covered with erosion control pads, mats or similar erosion control devices until
vegetative stabilization is installed.

45. Term of Monitoring; Annual Monitoring Reports Required: The permittee shall monitor the
mitigation sites to determine whether the mitigation site is meeting performance standards for
a minimum period of 5 growing seasons after completion of all the initial plantings, except for
the eelgrass mitigation area which will be monitored for ten years. Annual monitoring reports
are required for each of the three mitigation projects. Reports should clearly separate
information for advance mitigation areas that are unassigned as compensatory mitigation for
any permit. Permits that authorize the use of advance mitigation credits prior to final
determination of success by the Department will require additional monitoring and financial
security under the future permit conditions. For advance mitigation credits proposed for use
after the monitoring period has ended, future applications must provide a current year
monitoring report to show that the proposed mitigation area continues to meet the performance
standards established in this permit.
46. Annual Monitoring Report Due ate: Annual monitoring reports are due by December 31 of
each year for each of the three mitigation projects.
47. Extension of the Monitoring Period: The monitoring period may be extended for any of the
three mitigation projects, at the discretion of the Department, for failure to provide monitoring
reports, failure of the mitigation site to meet performance standards for two consecutive years
or when needed to evaluate re- planting or other corrective or remedial actions.
48. Release of Mitigation Obligation: Mitigation monitoring is required until DSL has officially
released the site from further monitoring.
49. Failure to Submit Monitoring Reports: Failure to submit the required monitoring report by
the due date may result in an extension of the monitoring period and /or enforcement action.
50. Contents of the Annual Monitoring Report: The annual monitoring report shall include the
following information:
a. Completed Monitoring Report Cover Sheet, which includes permit number, permit
holder name, monitoring date, report year, performance standards, and a determination
of whether the site is meeting performance standards.

51. Corrective Action May be Required: The Department retains the authority require corrective
action in the event the performance standards are not accomplished at any time within the
monitoring period.
To be deemed successful, the freshwater mitigation area shall meet the following
performance standards, as determined by DSL:
52. Establishment of Permanent Monitoring Locations Required: Permanent plot locations
must be established during the first annual monitoring in sufficient number and locations to be
representative of the site. The permanent plot locations must be clearly marked on the
ground.
53. Wetland creae Required: The CWM site will have a minimum of 0.15 acres of palustrine
emergent, depressional /closed permanent (HGM) wetland as determined by a wetland
delineation, as specified by the Department, during spring of a year when precipitation has
been near normal, vegetation has been established, and irrigation has been removed for at
least two years.
54. Native Species Cover: The cover of native species, as defined in the USDA Plants
Database, in the herbaceous stratum is at least 60 %.
55. Invasive Species Cover: The cover of invasive species is no more than 10 %. A plant
species should automatically be labeled as invasive if it appears on the current Oregon
Department of Agriculture noxious weed list, plus known problem species including Phalaris
arundinacea, Mentha pulegium, Holcus lanatus, Anthoxanthum odoratum, and the last crop
plant if it is non - native. Non - native plants should be labeled as such if they are listed as non-
native on the USDA Plants Database. Beginning in Year 2 of monitoring, DSL will consider a
non - native plant species invasive if it comprises more than 15% cover in 10% or more of the
sample plots in any habitat class, and increases in cover or frequency from the previous
monitoring period. Plants that meet this definition will be considered invasive for all successive
years of monitoring.
56. Bare Substrate Cover: Bare substrate represents no more than 20% cover.
57. Species Diversity: By Year 3 and thereafter, there are at least 6 different native species. To
qualify, a species must have at least 5% average cover in the habitat class, and occur in at
least 10% of the plots sampled.
58. Prevalence Index: Prevalence Index is <3.0.

59. Establishment of Monitoring Locations Required: Transect locations must be established
during the first annual monitoring in sufficient number and locations to be representative of the
site. The transect locations must be clearly marked on the maps and drawings used in the
monitoring reports.
60. Eel grass Acreage and Density Required: The CWM site will have established a minimum of
7.3 acres of eelgrass beds whereby a minimum of 2.43 of these acres will be medium to high
density eelgrass beds and the remainder of the 7.3 acres within the re- contoured area would
classify as low density eelgrass beds as documented by annual monitoring. Density classes
are defined as follows: less than 10% cover equals an absence of eelgrass bed, low density
equals approximately 10% to 39% cover, medium to high density equals approximately 40% or
greater.
61. Transplanting from Donor Sites: Transplanting of native eelgrass plants from donor beds to
the mitigation site is authorized under the following conditions: Plants may be collected from
identified donor beds with medium to high density ( >40% cover) of native eelgrass. A grid
collection pattern will be used with >1 meter spacing between collection areas. No more than
10% of the area of each bed will be harvested, and harvest is limited to areas with medium to
high density ( >40% cover) native eelgrass. Monitoring the donor sites along established
transects will be provided for a minimum of 3 years after collection and results included in
annual reports. Eelgrass cover in donor sites will be at least 40% cover by the third year after
harvest.
62. Invasive Species Cover: The cover of non - native eelgrass species (Z. japonica) shall be no
more than 15% for the duration of the monitoring period.

following performance standards, as determined by DSL:
63. Mudflat/Low Marsh Acreage Required: Construct a new bridge in East Bay Drive to allow
tidal exchange between Kentuck Inlet and the "back nine" of Kentuck Golf Course to
reestablish tidal flow to approximately 33.18 acres (required mitigation). The bridge shall be
constructed as designed and presented in the application. This action has the potential to
enhance 10.42 acres that is proposed for advance mitigation. Advance mitigation areas are
expected to consist of mudflat with the potential for high marsh along higher elevations.
64. Channels: Modified or newly constructed channels within the mitigation site will be
meandering as much as possible to avoid fish entrapment. Success will be determined
through review by an Oregon Department of Fish and Wildlife fish biologist.
65. Establishment of Monitoring Locations Required (Vegetated Areas): Transect locations
must be established during the first annual monitoring in sufficient number and locations to be
representative of the site. The transect locations must be clearly marked on the maps and
drawings used in the monitoring reports.

Page 12 of 12
66. Invasive Species Cover: The cover of invasive species in all mitigation areas is no more than
10 %, except Spartina species which have a zero tolerance. A plant species should
automatically be labeled as invasive if it appears on the current Oregon Department of
Agriculture noxious weed list, plus known problem species including Phalaris arundinacea,
Mentha pulegium, Holcus lanatus, Anthoxanthum odoratum, and the last crop plant if it is non-
native. Non - native plants should be labeled as such if they are listed as non - native on the
USDA Plants Database. Beginning in Year 2 of monitoring, DSL will consider a non - native
plant species invasive if it comprises more than 15% cover in 10% or more of the sample plots
in any habitat class, and increases in cover or frequency from the previous monitoring period.
Plants that meet this definition will be considered invasive for all successive years of
monitoring.
67.eetation Habitat Mapping Required (Advance Mitigation): Vegetation communities in
the advance mitigation area will be mapped in annual reports. This map should distinguish
mudflat (unvegetated), low marsh, and high marsh habitats.
68. Special Vegetation Standards in ih Marsh Habitats: The density of woody vegetation in
high marsh habitats is at least 1,600 native plants (shrubs) and /or stems (trees) per acre, OR
the cover of is at least 50% by year 5 of monitoring. Native species volunteering on the site
may be included, dead plants do not count. After the overstory has reached 50% cover, the
cover of invasive species may exceed 10 %, but may not exceed 30% cover.
69. Construction Criteria: Construct a new cross dike between the front and back nine, with a
standard tidegate to drain the front nine to the back nine; construct the tidegate array through
the Kentuck Slough dike allowing the majority of the flow from Kentuck Slough to enter the
back nine. Success will be determined through review of the tidegate array by an Oregon
Department of Fish and Wildlife fish biologist. The dike shall be constructed as proposed and
the tidegates will function as designed or modifications will be required.
70. Dike Maintenance /Repair Criteria: Dike repair and maintenance of approximately 2,250
linear feet of existing dike between Kentuck Slough and Kentuck Golf Course. No additional
wetland impacts are requested or authorized as part of the dike maintenance.
