1.0 EXECUTIVE SUMMARY



Coastal Resources Management, Inc. conducted an eelgrass transplant at the Orange Coast
College School of Sailing and Seamanship boat basin in September 2010. The project was
conducted to mitigate the loss of 105 square meters (1,133 square feet) of eelgrass vegetation
removed as a consequence of dock renovations in the boat basin, located along Mariners
Mile, in the City of Newport Beach, Ca.

CRM transplanted 192 bundles of eelgrass encompassing 180 square meters of eelgrass
(1,937 square feet) at the project site (a mitigation to impact ratio of 1.74 to 1) in September,
2010.

At the end of the first-year of post-transplant monitoring (September 2011), eelgrass
transplant areal cover success criteria was exceeded as defined in the Southern California
Eelgrass Mitigation Policy (SCEMP). A total of 117.4 square meters of eelgrass habitat
was mapped. A value of 88 square meters (70%) of the adjusted mitigation to impact
amount (126 square meters) was required at the end of the first year monitoring program.
Eelgrass turion density for the Year 1 transplant monitoring program also exceeded
density criteria as defined in the Southern California Eelgrass Mitigation Policy. Eelgrass
turion density was 72 turions per square meter, compared to 24 and 93 turions per square
meter prior to the project impact (2004 and 2005, respectively). The target value for the
Year 1 turion density success criteria was 30% of the project area density.

At the end of the second year of the five-year transplant monitoring program (September
2012) the eelgrass transplant at the Orange Coast College School of Sailing and
Seamanship exceeded mitigation success criteria for areal cover as defined in the
Southern California Eelgrass Mitigation Policy (Section 10 Success Criteria). The
transplant site attained a value of 144.1% (182.2 sq m) of the adjusted impact area (AIA)
compared to a required 85% of the adjusted impact area (107 sq m). Eelgrass turion
density exceeded density criteria as defined in the Southern California Eelgrass
Mitigation Policy (Section 10 Success Criteria). The mean shoot density value in the
transplanted bed (124.5 turions per sq meter) was 135% of the reference site density (92
turions per sq m), and between 127% (2004) and 508% (2005) of the pre-project area
density (2005). A value of 70% is required at the end of the second year of monitoring.
At the end of the third-year of the five-year transplant monitoring program the eelgrass
transplant at the Orange Coast College School of Sailing and Seamanship exceeded
mitigation success criteria for areal cover as defined in the Southern California Eelgrass
Mitigation Policy (Section 10 Success Criteria). The transplant site attained a value of
182.6 % (280.2 sq m) of the adjusted impact area (AIA) compared to a required 100% of
the adjusted impact area (126 sq m).
Eelgrass turion density at the transplant site during Year 3 (66.8 turions per square meter)
attained 68 percent of the required 70% turion density criteria as defined in the Southern
Coastal Resources Management, Inc.

ii
California Eelgrass Mitigation Policy (Section 10 Success Criteria). However, the
Harbor Island Reference Site (64.9 turions per square meter) was 66% of the 70% value,
indicating the decrease at the transplant site was related to natural variation. Density
declined by about 50% at both sites compared to the survey results in 2012.
The next scheduled eelgrass transplant monitoring survey (Year 4) is September 1st, 2014.

2.0 INTRODUCTION
Coastal Resources Management, Inc. conducted an eelgrass (Zostera marina) transplant project
for the Orange Coast College School of Sailing and Seamanship Dock Replacement Project in
Newport Harbor, Newport Beach, California on September 8th and 9th, 2010 (Coastal Resources
Management, Inc. 2010a). This was conducted in accordance with: Coastal Development
Permits (CDP) 5-04-167 and 5-04-167-A1 and the project eelgrass mitigation plan entitled
Eelgrass Mitigation Plan for the Orange Coast College School of Sailing and Seamanship
Facility Dock Replacement Project, dated 21 August, 2009 (Coastal Resources Management,
Inc., 2009).
Per provisions of the Southern California Eelgrass Mitigation Policy (National Marine Fisheries
Service, 1991 as amended), a five-year eelgrass transplant monitoring program is required to
document the success of the transplant project. This report presents the results of the third year
(36 month) post-transplant monitoring survey, and in accordance with the above-mentioned
permits and policies.
2.1 PROJECT AREA AND BACKGROUND
Orange Coast College School of Sailing and Seamanship is located within the City of Newport
Beach, California. The project site (Figure 1) is located on the north side of Lido Reach along
Mariners’ Mile, in Lower Newport Bay (Newport Harbor). The site coordinates are 33o 36.99’ N,
117o 55.08’ W. Project renovation tasks included removing 10 existing piles, installing an ADA
compliant gangway and landing, reinstalling the existing east gangway, installing a longer and wider
west gangway, reconfiguring the existing instructional docks, installing two new fingers and a new
dock/backwalk, installing eight new steel piles, and installing a new fire system (Figure 2). This
project resulted in the loss of 270 square feet (sq ft) of eelgrass. In addition, an unapproved
modular dock system was placed next to the approved dock in non-compliance with the final
approved plans of Coastal Development Permit No. 5-04-167 (Figure 3) resulting in the loss of
an additional 863 sq ft of eelgrass, totaling a loss of 1,133 square feet of eelgrass for the initial
project and the unpermitted modular dock system, as determined in the project’s postconstruction survey, conducted in December 2005 (Coastal Resources Management, Inc. 2006,
Figure 4). This system was approved by the California Coastal Commission in an amendment to
the original Coastal Development Permit in April 2010 (5-04-167-A1).
Eelgrass was present at depths between -6 and -7 feet Mean Lower Low Water. Eelgrass that
was removed exhibited extremely low densities, and ranged between 0 and 42 shoots per square
meter; the average shoot density was 24.7 +/ 15.8 (n=11 replicates). The eelgrass was in poor
condition and the blades were extremely short (approximately 2 to 4 cm in length). Overall, this
eelgrass habitat was determined to be of marginal habitat value. Post-construction, shading effects
monitoring surveys conducted in May 2007 and June 2008 by CRM indicated there was no regrowth
in the project area (Coastal Resources Management, Inc. unpublished data; Coastal Resources
Management, Inc. 2010b).

Project Mitigation Requirements
The loss of 1,133 sq ft (105 square meters)of eelgrass vegetation required the successful transplant
of 1,360 sq ft (126 sq meters) of eelgrass at the completion of a five-year eelgrass monitoring
program (National Marine Fisheries Service, 1991 as amended). Table 2 summarizes the amount of
material required for the project.

Review of the September 8th-9th 2010 Eelgrass Transplant
Eelgrass Donor Sites. Eelgrass material was collected from West Harbor Island and the
vicinity of Linda Isle (Figure 5). A third potential eelgrass collecting zone (Bayshores/John
Wayne Beach lacked eelgrass.
Eelgrass Transplant Site. Eelgrass bundles were manufactured by the shore-based eelgrass
transplant team during the mornings and early afternoons of September 8th and 9th at the OCC
transplant site (Figure 6 and Figure 7). The anchor/bundle method employed to produce eelgrass
bundles. Prior to the transplant, transplant guide lines were laid out to establish a 12 meter by 15
meter-long transplant area
A total of 192 bundles were planted on 1 meter centers within 180 square meters (1,937 square
feet) of bottom habitat at depths between -6 and -7 ft Mean Lower Low Water (MLLW). An
example of a planted eelgrass bundle is shown in Figure 8.

3.0 YEAR 3 (2013) TRANSPLANT MONITORING SURVEY METHODS
The second year, post-transplant eelgrass survey was conducted on August 8th, 2013 by Mr. Rick
Ware, Senior Marine Biologist and Tom Gerlinger, Marine Biologist. The condition of the
transplanted bed was initially inspected by conducting a reconnaissance dive. An intensive
habitat mapping survey followed this effort. A reference (control) eelgrass bed was also
monitored in tandem with the Orange Coast College School of Sailing and Seamanship eelgrass
transplant site. The reference site was located on the west side of Harbor Island. Eelgrass areal
cover and density information for this bed dates back to 1998 (Chambers Consultants, Inc. and
Coastal Resources Management, Inc., 1998). It was also mapped by Coastal Resources
Management for harbor-wide eelgrass mapping surveys in 2003, 2006, 2010 (Coastal Resources
Management, Inc. 2005, 2010a, and 2011. A 30 meter section of the bed was established as the
long-term reference site.
The monitoring survey was conducted using Wide Area Augmentation System (WAAS) GPS
(Global Positioning System) technology and differential GPS post-processing. A SCUBAdiving biologist towed a small yellow “pop” buoy around the perimeter of the eelgrass beds. A
second biologist in an 11 ft-long kayak trailed the SCUBA-diving biologist and continuously
recorded WAAS GPS readings centered on the visible yellow SCUBA tank of the diver or the
yellow surface buoy towed by the diver. GPS readings were collected at one second intervals
using a Thales Mobile Mapper hand held GPS/GIS unit. The estimated GPS error of the Thales
Mobile Mapper unit with differential correction is less than 1 meter.
The GPS data were downloaded into a computer using Thales Mobile Mapper software. GIS
shape files were then developed from the track data and overlaid on a geo-referenced, highresolution, photograph of the project area. Final presentation graphics and surface area
calculations of eelgrass habitat were made using both ArcGIS 10.0 and GPS TRACKMAKER
PRO software.
Eelgrass turion counts were made throughout the transplanted eelgrass bed as well as the Harbor
Island reference eelgrass bed using 0.07 square meter replicated sampling quadrats. These data
were standardized to turion counts per one square meter.
Data were also collected on eelgrass depth ranges, sediment types, and common marine
organisms observed within and nearby the eelgrass beds. Depths were standardized to Mean
Lower Low Water datum (NOAA Newport Bay Entrance Channel Reference Station).

4.0 MONITORING SURVEY RESULTS
Appendix 1 provides the required Southern California Eelgrass Mitigation Policy Monitoring
and Compliance Reporting Summary. The survey was conducted under clear skies and an air
temperature of 73 degrees Fahrenheit. Underwater visibility ranged four to six feet. High tide
occurred during the survey at 1103 noon (5.3 ft MLLW). Water temperature was 71 degrees
Fahrenheit. Depths in the eelgrass bed varied between 5.5 ft and 8.5 ft MLLW. Depths in the
reference site area were shallower, and varied from -0.3 to -6 ft MLLW, although density data
were collected at -5.5 to 8.5 ft MLLW, at depths similar to the transplant site. Sediments
consisted of muds and silts at the transplant site. At the reference site, the sediments near the
bulkhead were compacted fine sands. At depths similar to the transplant site, sediments were
finer, and were sandy silts.
4.1 AREAL COVER
Eelgrass Mitigation Area. Transplant site data for all surveys is provided in Table 2 and
eelgrass areal cover during the 2013, Year 3 monitoring survey is shown in Figure 9. The total
the August 2013 survey was 230.8 sq meters (2,483.4 sq ft). Comparatively, the amount of
eelgrass habitat mapped during September 2012 was 182.2 square meters (1,960.1 sq ft) and
during the Year 1 survey was 117.4 sq m (1,263 sq ft). The amount of eelgrass in 2013 exceeds
the amount of eelgrass required at the end of the third year of monitoring (126 sq m) by 104 sq
meters. The eelgrass areal cover data trends for the transplant and the reference sites are shown
by year, in Figure 11, relative to the required amount of eelgrass at the end of each survey year
(Adjusted Impact Area).

4.2 EELGRASS TURION DENSITY
Eelgrass Mitigation Area. Turion density during the Year 3 monitoring survey was 66.4 +/24.8 per square meter, n=34 replicates (Table 3). Density at the site decreased by about 50%
compared to Year 2 (mean=124.5 turions per square meter) but was similar to Year 1 (72.1
turions per square meter (Table 3). The range in individual turion densities varied between 28.6
and 114.3 turions per square meter. The required eelgrass turion density value at the end of the
second year of monitoring is 68.6 turions per square meter, based on a pre-project density value
of 98 turions per sq meter in July 2004 (Table 3). The density at the transplant site and the
reference site were slightly lower in values compared to the required 85% of the adjusted impact
density value (98 turions per sq meter) for the Year 3 survey (Figure 12)
Prior to the installation of the docks in the Orange Coast College School of Sailing and
Seamanship Basin, eelgrass density varied between 24 and 98 turions per square meter between
2004 and 2005, respectively (Coastal Resources Management, Inc., 2005a, 2005b). In 2005
following the installation of the boat docks, density fell to 3 turions per square meter (Coastal
Resources Management, Inc., 2006). In 2008, no eelgrass was found within the boat basin
(Coastal Resources Management, Inc. 2010b). It should be noted that eelgrass throughout much
of the mid-section of Newport Harbor and Upper Newport Bay either declined in cover and/or
density during this period (Coastal Resources Management, Inc. 2010b). Increases in eelgrass
turion density however, were observed in early 2011 in some of these areas (Coastal Resources
Management, Inc. 2011).

In 2013, the red algae Gracilariopsis sp. again formed a low, canopy of algae at the transplant site
The soft ectoproct Zoobotryon verticillatum was present at both the at the OCC Boat Basin
Transplant Site and the Reference Site. Other invertebrates observed included the bubble snail
(Bulla gouldiana) and the burrowing anemone (Pachycerianthus fimbriatus). Fish observed during
included the survey included round sting ray (Urolophus halleri), black perch (Embiotoca jacksoni)
and topsmelt (Atherinops affinis).
5.0 SUMMARY, CONCLUSIONS, AND COMPLIANCE
WITH EELGRASS MITIGATION POLICY
CONCLUSIONS AND COMPLIANCE TO EELGRASS MITIGATION POLICY
The Southern California Eelgrass Mitigation Policy states: “the mitigation site shall achieve a
minimum of 100 percent area of eelgrass and 85 percent density as compared to the adjusted project
impact area after the second year”. (Section 10, Mitigation Success)

At the end of the third-year of the five-year transplant monitoring program the eelgrass
transplant at the Orange Coast College School of Sailing and Seamanship exceeded
mitigation success criteria for areal cover as defined in the Southern California Eelgrass
Mitigation Policy (Section 10 Success Criteria). The transplant site attained a value of
182.6 % (280.2 sq m) of the adjusted impact area (AIA) compared to a required 100% of
the adjusted impact area (126 sq m).


Eelgrass turion density at the transplant site during Year 3 (66.4 turions per square meter)
attained 68% of the required 70% turion density criteria as defined in the Southern
California Eelgrass Mitigation Policy (Section 10 Success Criteria). However, the Harbor
Island Reference Site (64.9 turions per square meter) was 66% of the 70% value, indicating
the decrease at the transplant site was related to natural variation. Density declined by
about 50% at both sites compared to the survey results in 2012.
