SUMMARY
San Diego Gas and Electric (SDG&E) proposes to improve a portion of the access route
from El Camino Real to Tower 73 by placing gravel on a portion of the route which
sometimes becomes impassible during heavy rains. Pacific Southwest Biological Services
(Pacific Southwest) conducted a biological survey and wetland delineation to determine
if the proposed gravel placement would have potential impacts to biological resources.
Southern willow scrub and ruderal wetland habitats are both in the vicinity of the
access route. Graveling will impact the ruderal wetland, and may impact the southern
willow scrub, depending on the final design width for the gravel road. No sensitive
plant or animal species were observed, although there is a low probability that least
Bell's vireo (Vireo bellii pusillus) could use the southern willow scrub during the
breeding season. Forty species of plants were observed on-site, of which 25 were
normative. Twelve species of animals were observed on-site, including two butterflies,
seven birds, and three mammals.
INTRODUCTION
Pacific Southwest Biological Services, Inc. (Pacific Southwest) was retained by San Diego Gas and
Electric (SDG&E) on 13 August 1996 to conduct a delineation of waters of the United States, including
wetlands jurisdictional under the U.S. Army Corps of Engineers (Corps) pursuant to §404 of the Clean
Water Act, and streambeds of the state jurisdictional under CDFG pursuant to §1600 et seq. of the
California Fish and Game Code on the access route to SDG&E Tower 73. On 21 August 1996,
SDG&E requested that the study be expanded to include biotechnical surveys on this area. The access
route is adjacent to a riparian area which feeds into Agua Hedionda Lagoon. This access route is
currently driven by SDG&E crews without improvement; occasionally, however, it is impassible during
heavy rains. SDG&E proposes to lay rock and/or gravel to create a permanent access road through
the portion of the route that becomes impassible due to saturated soils. The final design for the road
has not been completed, since SDG&E will consider the results of the biological surveys. As a result,
it is not the intent of this report to depict the final impacts of the road. However, this report will
discuss likely impacts to the extent possible without the final design, and will provide SDG&E with
the information required to minimize impacts of the design on the natural resources of the site.

GENERAL SITE CHARACTERISTICS
LOCATION
The site is located in the Agua Hedionda Land Grant, Township 12 South, Range 4 "West of the San
Bernardino Base and Meridian, USGS 7.5' San Luis Rey Quadrangle (Figures 1 & 2). The site is
immediately south of El Camino Real east of Kelley Drive. This survey investigated potential wetlands
from El Camino Real to approximately 400 feet south of the road, in a belt approximately 50 feet wide
with the toe of the slope for the adjacent nursery as an eastern boundary. The floral and faunal
resources of the site were also investigated within and adjacent to this belt.
GENERAL PHYSIOGRAPHY
The property consists of relatively flat terrain near sea level (less than sixty feet elevation). Soils are
mapped as Salinas clay loam, 2 to 9 percent slopes (SbC), which are characterized as mildly alkaline
low-chroma clay loams (Bowman 1973). These soils are not listed as hydric in the San Diego County
Hydric Soils List (USDA - SCS 1992), but contain inclusions of soils which may be hydric under
criteria 2B3, "Soils in Aquic suborder, Aquic subgroups, Albolls suborder, Salorthids great group, Pell
great groups of Vertisols, Pachic subgroups, or Cumulic subgroups that are poorly drained or very
poorly drained and have a frequently occurring water table at less than 1.5 feet from the surface for a
significant period (usually more than 2 weeks) during the growing season if permeability is less than
6.0 in/hr in any layer within 20 inches" (USDA-SCS 1992). The underlying geology is mapped as
Tertiary Marine (Rogers 1965).
Fresh water enters the site from the north via an unnamed creek and as runoff from the surrounding
slopes. Some urban runoff from developed areas to the northeast of the site also flows into the
unnamed creek.
CLIMATE
The site is located in the coastal plain region of the County, and as such is subject to mild temperatures
in both the winter and summer. The growing season is virtually year-round, approximately 360 days.
Rainfall is approximately ten inches, but morning and afternoon fog increases the moisture availability
and decreases evaporation in this region (Bowman 1973).
LAND USES
The access route is currently driven by SDG&E crews without improvement. East of the access route
is a nursery built on fill. West of the access route is a riparian area. Both the access route and adjacent

are located west of the riparian area, south of the access route, and east of the nursery.
METHODS
BOTANICAL AND ZOOLOGICAL SURVEY
A botanical and zoological survey of the site was conducted by Marcia Dustin Mann on 22 August
1996. At the onset of the survey air temperature was 64° Fahrenheit, wind velocity at 0 miles per
hour, with 100% overcast skies. All portions of the site were walked. Binoculars (8 x 42 power) aided
in the identification of avifauna! species. All vegetation habitats were mapped.
The scientific nomenclature used in this report is from the following standard references: vascular plants
(Hickman 1993; Munz 1974; Beauchamp 1986), vegetation habitats (Holland 1986), wildlife habitats
(Mayer, et al. 1988), amphibians and reptiles (Jennings 1983 and Stebbins 1966), birds (American
Ornithologists' Union 1983, 1989), and mammals (Jones, et al. 1992).
VEGETATION MAPPING
The mapping of vegetation and habitat types was conducted Elizabeth A. Olsen and Marcia Dustin
Mann on 20 and 22 August, 1996 using the Holland system of vegetation classification. The on-foot
survey covered all areas of potential impact. Vegetation habitat types were mapped in the field and
transferred to a 1" - 200' aerial photograph in the office.
DELINEATION OF JURISDICTIONAL WETLANDS OF THE U.S. AND STATE
A delineation was conducted within the study site to determine the extent of jurisdictional waters of
the United States including wetlands subject to U.S. Army Corps of Engineers jurisdiction under the
Clean Water Act, and waters of the State subject to California Department of Fish and Game
Streambed Alteration Agreements. The delineation was performed by Wetland Biologist Elizabeth A.
Olsen on 20 August 1995. Delineation results were mapped in the field on an aerial photo with a scale
of approximately 1" - 200'.
The delineation for federal jurisdiction used field methods and criteria consistent with current guidance
from the U.S. Army Corps of Engineers (Corps) and the 1987 Manual (Environmental Laboratory
1987). Wetland delineations are made using a three-parameter system based on hydrophytic vegetation,
8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc.
PSBS # 145 i Augment
hydric soils, and hydrology (frequency of saturation, flooding and inundation). Methods of observation
and determination for each wetland criterion are offered below.
Hydrophytic Vegetation
Vegetation habitats which met the criteria of wetland-associated vegetation (hydrophytic vegetation)
were dominated by species classified as obligate wetland plants (OBL), facultative wetland plants
(FACW), or facultative plants (FAC) based on the National List of Plant Species that Occur in
Wetlands (USFWS 1988).
Hydric Soils
The San Diego Soil Survey (Bowman 1973) and the San Diego County Hydric Soil List (USDA-SCS
1992) were consulted to determine the mapping units listed for the study site and the hydric status of
these soils. In addition, to confirm the presence of hydric soils, soil test pits were examined at each
data point in the determination. These soils were examined for physical and chemical evidence of
hydric conditions. Loamy soils were evaluated using the chroma index from the Munsell Soil Color
Charts (Munsell Color 1974). Other indicators of hydric soils such as vertical organic streaking in
sandy soils, mottling, and the presence of spodic and organic pans were also used as indicators of hydric
soils.
Wetland Hydrology
Hydrologic wetland indicators included evidence of flow, ponding, and accumulations of debris and
sediments. Additional hydrologic indicators were used to define any non-wetland waters of the United
States.
The potential for wetlands jurisdictional under the CDFG pursuant to Fish and Game Code §1600 et
seq. was also investigated. The breadth of areas subject to regulation by CDFG under §1600 are less
clearly defined than those regulated by the Corps; however, in general, the policies are fairly consistent.
It is clear that all rivers, streams, lakes and streambeds which may exhibit "intermittent flows of water"
are covered by the California statutes. Section 1600 et seq. jurisdiction extends over all riparian habitat
supported by a river, stream, or lake regardless of the riparian area's federal wetland status.
BIOLOGICAL SURVEY LIMITATIONS
Depending on the season during which a field survey is conducted, some sensitive amphibians, reptiles,
birds, mammals, and annual plants can be difficult or impossible to inventory.
8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc.
PSBS # 145 i Augment
The effects of drought may cause temporary shifts in local distribution of species which may recolonize
a site when more typical rainfall patterns resume.
Many groups of vertebrates are difficult to find during short-term field surveys. Some, such as
migratory or nomadic birds, may be absent from the site when the field work is conducted. Other
species occur in low densities and are easily missed.
However, through literature review, study of museum records, and knowledge of the habitat
requirements and distribution patterns of individual species, the probability of a given species being
present on a site can often be fairly accurately predicted. Species which are declining or have naturally
patchy distribution patterns may not be present in areas of what appears to be suitable habitat. Thus,
some habitats must be surveyed at the proper season to determine the status of certain species. Since
this survey has been conducted in late summer, negative results concerning breeding birds are not
conclusive. A spring survey would be required to verify use by sensitive breeding birds.
RESULTS
VEGETATION HABITATS
Vegetation habitats are assemblages of plant species that usually coexist in the same area. The
classification of vegetation habitats is based on the life form of the dominant species within that habitat
and the associated flora. The vegetation types follow those of Holland (1986). In some instances, there
may be an assemblage of plant species for which there is not an adequate description in this reference.
In that case, a category was selected which reflected both the floristics and physiognomy of that
assemblage. There are three vegetation habitats that occur within the study area (Figure 3).
SOUTHERN WILLOW SCRUB
The southern willow scrub on-site is dominated by arroyo willow (Salix lasiolepis). The diameter at
breast height (dbh) of the willows averages 3-4" dbh with a maximum of approximately 8" dbh. Other
tree species in the southern willow scrub were red willow (Salix laevigata) and Goodding's black willow
(Salix gooddingii). The average tree height is approximately 15 feet with a maximum height of 20 feet.
A fairly closed tree canopy blocks out most light; therefore, there is not a well-developed herbaceous
understory. Common plants in the patchy understory are umbrella flatsedge (Cyperus involucratus),
Kikuyu grass (Pennisetum clandestinum), and cocklebur (Xanthium strumarium).

PSBS # 145 i Augment
RUDERAL WETLAND
Ruderal refers to land recently or continually disturbed in which the earliest successional plant species
are typically dominant. These species in coastal San Diego County tend to be normative, often
invasive, annuals. This ruderal area is also a wetland and the plants are hydrophytic. Dominant species
of the ruderal wetland are cocklebur, Bermuda grass (Cynodon dactylon), and spearscale (Atriplex
triangulems}.
RUDERAL UPLAND
The dominant species of the upland ruderal (see above for definition) area on-site are castor-bean
(Ricinis communis), Bermuda grass, shortpod mustard (Hirschfeldia incana), and fennel (Foeniculum
vulgare).
FLORA
Forty species of plants were observed during the surveys. Twenty-five of these species, approximately
63 percent, are plants that are not native to California. The high percentage of non-native species on-
site is expected on disturbed land. See Appendix 1 for a complete floral list.
FAUNA
Twelve species were observed on-site (Appendix 2).
INVERTEBRATES
Two invertebrates, butterflies, were observed during the 20 August 1996 survey: Lorquin's admiral
(Basilarchia lorquini) and anise swallowtail (Papilio zelicaon).
AMPHIBIANS
No amphibians were observed during the 22 August 1996 survey.
REPTILES
No reptiles were observed during the 22 August 1996 survey.
BIRDS
During the 22 August 1996 survey of the site, 7 species of birds were observed utilizing the property.
A complete list is presented in Appendix 2. Surveys conducted during different times of the year
would undoubtedly encounter additional species, particularly those which may use the site during their
seasonal migration.
MAMMALS
Three mammals were detected during the 22 August 1996 survey: desert cottontail (Silvilagus
audubonii), coyote (Canis latrans), and domestic dog (Canis domesticus).

SENSITIVE BIOLOGICAL RESOURCES
SENSITIVE VEGETATION COMMUNITIES
Sensitive habitats are those which are considered rare within the region, are considered sensitive by the
County of San Diego or the California Department of Fish and Game (CDFG), or support sensitive
plants or animals.
SOUTHERN WILLOW SCRUB
Southern willow scrub vegetation habitat is characterized by dense, broad-leaved, winter-deciduous
riparian thickets dominated by one or more willow (Salix) species. Scattered emergent Fremont
cottonwood (Populus fremontii) and sycamore (Platanus racemosa) are often present. Most stands are
too dense to allow much understory development.
SENSITIVE FLORA
Sensitive flora include those listed by the United States Fish and Wildlife Service (USFWS) and/or
CDFG, candidates for listing by USFWS and/or CDFG, species considered sensitive by CDFG, floral
species considered sensitive by the California Native Plant Society (CNPS), and/or species considered
sensitive by the San "Diego Association of Governments (SANDAG). No sensitive plant species was
observed during the 22 August 1996 survey and none is expected to occur on-site.
SENSITIVE FAUNA
Sensitive fauna includes those listed by USFWS and CDFG; candidates for listing by USFWS or
CDFG; species considered sensitive by CDFG; and species considered sensitive by SANDAG. No
sensitive fauna was detected on-site. The federally endangered southwestern willow flycatcher (Epidonax
traillii extimus) would not be expected in this patch of southern willow scrub due to the lack of open
water on-site or within 100 meters of the site during a significant portion of the May-September
flycatcher breeding season.
The federally endangered least Bell's vireo (Vireo bellii pusillus) has a low probability of occurring on-
site. None has been reported in this small drainage and none were detected during the survey either
on-site or in the immediate vicinity.

WETLAND DELINEATION
Two wetland types are present on the site: southern willow scrub and ruderal wetland (Photograph 1,
Figure 3). The southern willow scrub was present in the main riparian channel only (Photographs 1
and 2). Wetland data sampling indicates that it is dominated by arroyo willow, Goodding's black
willow, umbrella flatsedge, and tall nutsedge (Cyperus eragrostis) patasheet 1). Prairie bulrush (Scirpus
robustui), castor-bean, and pampas grass (Cortaderia sp.) were also noted (Photograph 3). Soils consisted
of coarse to medium sands typical of Riverwash soils (Photograph 4). This Riverwash extended the full
18" inches of the soil pit. Hydrologic indicators include driftlines and debris in the vegetation,
sediment deposition, and drainage patterns.
The ruderal wetland area is located between the riparian southern willow scrub and the toe of the fill-
slope associated with the adjacent nursery (Photograph 1, Figure 3). In some areas, the willow canopy
overhangs the ruderal wetland, but it is generally dominated by hydrophytic weedy herbaceous species
(Photograph 5). These species include cocklebur, spearscale, Bermuda grass, Kikuyu grass, western
ragweed (Ambrosia psilostacbya), and bristly ox-tongue (Picris echioides) (Datasheets 2-4). There are also
some arroyo willow saplings, prairie bulrush, and tall nutsedges, but these species did not constitute
dominants. There was evidence of sediment deposition throughout the ruderal wetland area, indicating
that during periods of high flows this area is subject to riverine processes of the adjacent stream. Soils
varied through the ruderal wetland portion of the site. In the lowest portions of the ruderal wetland
soils consisted of approximately 11" of Riverwash overlaying a low chroma clay loam, which was
saturated at the time of fieldwork (Datasheet 2). At a point further south and slightly upgrade from
Datasheet 2, the soils were loam at the surface, with a low chroma matrix (10YR 4/2) and many
prominent mottles (10 YR 4/6) (Photograph 6, Datasheet 3). Further south soils consisted of
approximately 4" of fine sand overlaying low chroma clay which contained oxidized rhizospheres
(Datasheet 4). South of the nursery, the path travels up slope and enters an upland ruderal area
dominated by non-native grasses and sweet fennel (Photograph 8).

DISCUSSION
WETLANDS
Based on the results of fieldwork, the area SDG&E is considering for the access road to Tower 73 does
constitute jurisdictional wetlands pursuant to §404 of the Clean Water Act. The areas identified on
Figure 3 as southern willow scrub are under the jurisdiction of both the Corps and CDFG. The area
identified as ruderal wetland is under the jurisdiction of the Corps only. SDG&E proposes to construct
a gravel access road to Tower 73 with the least amount of impact to the resources. Pacific Southwest
recommends placing the road so that it abuts the toe of the fill slope for the adjacent nursery. This
will not avoid the wetlands, but will avoid or minimize impacts to the southern willow scrub, which
is the most sensitive of the two wetland habitats. If the access road extends from El Camino Real,
through the ruderal wetland to the ruderal upland to the south, it will impact approximately 350 linear
feet of ruderal wetlands. The square-footage of the impact will depend on the width of the access road.
If the width is limited to 10 or 12 feet, it is likely that no willows will be impacted by the project.
The impact to the function of the ruderal wetland can further be minimized by using large cobble sized
rocks as a base for the road, rather than small gravel. The larger rock will have larger spaces between
them. In the event that the road bed sinks into the soil when the winter rains arrive, these larger
spaces between the rocks will accommodate subsurface groundwater flow more effectively than finer
material would. A top layer or finer material could then to be placed over the base rock to allow
smoother access for SDG&E machinery.
Since the ruderal wetland is $404 jurisdictional, any impacts to this area may need to be mitigated.
Because this wetland is dominated by normative invasive species, and does not constitute a sensitive
native habitat, the mitigation ratio would likely be relatively low, such as 1:1. If any of the southern
willow scrub habitat is impacted, this will likely need to be mitigated at a much higher ratio, perhaps
2:1 or 3:1.
The site is also located along a streambed of the state. If none of the southern willow scrub habitat
is impacted in the construction of the road, it is unlikely that a Streambed Alteration Agreement from
CDFG will be required. However, due to its proximity, liaison with this agency is recommended to
confirm this. The site may also be located within the Coastal Zone, and therefore under the
jurisdiction of the Coastal Commission. Liaison with this agency is also recommended.
