PSBS # 145 i Augment BIOLOGICAL REPORT OF ENVIRONMENTAL CONDITIONS AT THE SITE FOR THE ACCESS ROAD FOR TOWER 73, SAN DIEGO COUNTY, CALIFORNIA Pacific Southwest Biological Services, Inc. 30 August 1996 (Revised 4 September 1996) 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. 8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc. PSBS # 145 i Augment 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.

Suburban neighborhoods 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). 8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc. 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). 8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc. PSBS # 145 i Augment 10 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. 8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc. PSBS # 145 i Augment 11 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). 8/30/96 (Revised 9/4/96)Pacific Southwest Biological Services, Inc. PSBS # 145 i Augment 12 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. 8/30/96 (Revised 9/4/96) Pacific Southwest Biological Services, Inc.
