Sc., President PSBS #T823 LDS Meeting House-Cardiff 1 i& 2 Site Carlsbad, California Biotic Resources Assessment 5 March 2001 SUMMARY A biological assessment of the LDS Meeting House-Cardiff 1 & 2 site revealed an area supporting three vegetation types: Southem Willow Scrub, Freshwater Marsh, and Disturbed Habitat. No sensitive faunal species and one sensitive floral species were observed. Areas of Southem Willow Scmb and Freshwater Marsh are under the jurisdictions of the U. S. Army Corps of Engineers and Califomia Department of Fish and Game. A minor change in the proposed grading plan is proposed to deal with these jurisdictional areas. It is recommended that permits be obtained prior to grading in these areas. INTRODUCTION Pacific Southwest Biological Services, Inc., (Pacific Southwest) performed a general biological assessment on the 6.817-acre site at the request of BSW Intemational. The purpose of the assessment was to respond on behalf of the client to a letter fi-om the City of Carlsbad of 19 September 2000 requiring a biological analysis to enable environmental review for application for Conditional Use Permit and Hillside Development Permit. Emphasis is on consistency of the proposed project with the draft Multiple Habitat Conservation Program being prepared by the City. LOCATION The 6.817-acre parcel lies near the eastem boundary of the City of Carlsbad in north San Diego, County, Califomia. The map location is in the northwest quadrant of Section 6, Township 13 South, Range 3 West, and can be found on the USGS San Bemardino Base and Meridian 7.5' Rancho Santa Fe, Califomia quadrangle at UTM: 1 l-S: 477,300mE; 3,659,400mN (Figures 1 & 2). Access to the site from Interstate Highway 5 is east on La Costa Avenue past Rancho Santa Fe Road, then south on Camino de Los Coches to the site, which is adjacent on the north to the playing fields of Stagecoach Park. PROJECT DESCRIPTION The proposed project includes constmction of a church building with retaining walls and parking facilities. GENERAL PHYSIOGRAPHY The site is currently open land with no stmctures, although a sewer line manhole is visible along the southem boundary, and approximately 75 feet of concrete swale is found on the northwest boundary. An unnamed tributary to Encinitas Creek drains southerly along the westem side of the property. Elevation ranges from approximately 211 feet above mean sea level at the bottom of the drainage in the southwest comer of the site to approximately 262 feet along the eastem boundary. Residential housing lies adjacent to the west of this tributary, and also all along the site across Camino de Los Coches to the east. Stagecoach Park lies immediately south. Pacific Southwest Biological Services, Inc. PSBS #T823 Soils and geologic substrates mapped for the site are no longer relevant due to the prior grading and filling of the parcel. METHODS, SURVEY LIMITATIONS, AND DEFINITIONS METHODS Prior to field work. Pacific Southwest conducted a search of the Califomia Department of Fish and Game (CDFG) Natural Diversity Data Base (NDDB) for the USGS 7.5' Encinitas and Rancho Santa Fe, Califomia Quadrangles. This search revealed several federally- or state-listed species that may occur on or in the vicinity of the property. General zoological and botanical surveys were conducted on the site by Pacific Southwest. The zoological assessment was performed by wildlife biologist Comelius W. Bouscaren 15 Febmary 2001 (0720-0850 hours, temperature 42-43°F, skies clear, winds calm). Methods consisted of walking slowly over the site while watching and listening for wildlife. "Pishing", a technique commonly used to attract the interest of passerines and draw them into view, was occasionally employed. Binoculars (8.5x44) were used to assist in the detection and identification of wildlife. Visual and/or auditory detection, tracks, scats, bones, dens, and burrows confirmed species presence. The botanical inventory was performed by principal botanist R. Mitchel Beauchamp and field assistant Christian Lliles 28 Febmary 2001 during the hours 0830-0930. Conditions were optimal for observing vegetation. A checklist of observed plant species was maintained during the on-site investigation, and the boundaries of the various plant associations and habitat were mapped. The limits of the wetlands are clearly defined by the steep channel slopes. The site was of such limited size that the entire property could be covered by the biologists during their respective visits. The surveys included directed searches for rare and endangered or narrow endemic species of plants and animals. SURVEY LIMITATIONS AND DEFINITIONS Complete biological inventories of large sites may require a large number of field hours during different seasons as well as noctumal sampling for some animal groups, such as small mammals or migratory or nomadic birds. Depending on the season during which the field survey is conducted, amphibians, snakes, many mammals, owls and other noctumal birds, and annual plants are groups that can be difficult to inventory. The effects of drought may cause temporary shifts in the local distribution of species, which may recolonize the site in question when more normal rainfall pattems resume. Conversely, precipitation above the usual, such as those frequently referred to as El Nino events, may also bring about a temporary change in the normal distribution mosaic. However, through literature review, study of museum records, and knowledge of the habitat requirements and distribution pattems of individual species, the probability of a given species being present on a site can often be reasonably predicted by an experienced biologist. Due to the seasonal timing of the surveys, not all plant species would be observed on the site. However, sensitive plants with a strong potential to occur on the site are usually identifiable during most of the year by an experienced botanist. The surveys performed for this assessment are considered complete and accurate for the species of concem, unless otherwise noted. Pacific Southwest Biological Services, Inc. PSBS #T823 The scientific nomenclature used in this report is from the following standard references: vascular plants (Beauchamp 1986, Hickman 1993, Munz 1974); vegetation communities (Holland 1986, Hanes 1977, Skinner and Pavlik 1994, Oberbauer 1996); wildlife habitats (Mayer et al. 1988); amphibians and reptiles (Collins 1990); birds (American Omithologists' Union 1998); and mammals (Jameson and Peeters 1988, Jones et al. 1992). Vegetation Communities Vegetation communities are assemblages of plant species that usually coexist in the same area. The classification of vegetation communities is based upon the life form of the dominant species within that community and the associated flora. Nomenclature for vegetation communities, and vegetation community code classifications, conform to Holland as modified by Oberbauer. A description of the vegetation communities with the appropriate code (#) follows. SURVEY RESULTS BOTANICAL RESOURCES Vegetation Communities On-Site The site, aside from the drainages, consists of disturbed, predominantly bare areas. No native upland vegetation occurs on the site. Non-native aimuals dominate the majority of the site. The drainages on the site, which are unnamed tributaries of Encinitas Creek, are vegetated with a mixture of Cattails (Typha sp.) and Willows (Salix sp.), with dominance of Cattails. The narrow nature of the features precludes assignment to any particular vegetation type, which are given here only for purposes of qualitative description of the drainages. Disturbed Habitat (#11300) (6.05 acres) The majority of the site is highly disturbed and virtually devoid of native vegetation. Most of the property appears to have been previously graded, although how recently is unknown. Weedy species that are abundant include Russian-thistle (Salsola tragus). Red-stem Filaree (Erodium cicutarium), Hottentot-fig (Carpobrotus edulis), Short-pod Mustard (Hirschfeldia incana), Tocalote (Centaurea melitensis), and a variety of non-native grasses such as Ripgut Grass (Bromus diandrus). Red Brome (Bromus madritensis spp. rubens), and Slender Wild Oat (Avena barbata). Southern Willow Scrub (#63320) (as part of 0.76 acre of jurisdictional area) The majority of the remnant native vegetation on the site is Southem Willow Scmb. This community, on the part of the parcel proposed for grading, is supported by flows from the east through a culvert beneath Camino de Los Coches. The drainage along the westem boundary, in the drainage that would remain undisturbed, is supported by the main aforementioned unnamed tributary. The most prominent species is Arroyo Willow (Salix lasiolepis) to 35 feet in height with an occasional Goodding's Black Willow (S. gooddingii) and several Southwestem Spiny Rush (Juncus acutus spp. leopoldii) plants. The presence of Tamarisk (Tamarix parviflora) and Tree Tobacco (Nicotiana glauca), both non-native invasive plants, provides evidence of some degradation of this community. Understory species include Milk Thistie (Silybum marianum), Bristly Ox-tongue (Pieris echioides), Saltgrass (Distichlis spicata), Bull Thistle (Cirsium vulgare). Common Sow-thistle (Sonchus oleraceus), Westem Ragweed (Ambrosia psilostachya), and Curly Dock (Rumex crispus). Pacific Southwest Biological Services, Inc. PSBS #T823 Freshwater Marsh (#52410) (as part of 0.76 acre of jurisdictional area) This community is restricted to small patches above and below the remnant Southem Willow Scmb on the part of the parcel proposed for grading. The dominant species here is Southem Cattail (Typha domingensis), with some evidence of hybridization with Soft Flag Cattail (r. latifolia). This is not unusual since all North American species of Typha hybridize. The plants are up to 15 feet in height and form a closed canopy with virtually no understory because of the density of the growth. The understory on the fringes is identical with that of the Southem Willow Scmb. Flora The observed flora of the site totals 55 plant taxa, 34 (62%) of which are non-native and indicative of the high degree of disturbance of the site (Appendix 1). Most of the native plants are associated with the Southem Willow Scmb and Freshwater Marsh. Additionally, several cultivated plants occur in the drainage as escapes from cultivation from the adjacent northem property. ZOOLOGICAL RESOURCES The paucity of faunal species observed was expected in light of the high degree of disturbance on the site and the abundance of residential development nearby. One amphibian, one reptile, 20 avian, and one mammal species were observed (Appendix 2). Amphibians The field visit revealed only the Pacific Choms Frog (Pseudacris regilla), the most commonly heard frog on the Pacific Coast. This amphibian, chiefly a ground-dweller found among low plant growth near water, has adapted to a wide variety of habitats. Its distinctive call is readily recognized. No other amphibians are expected to occur. Reptiles The Westem Fence Lizard (Sceloporus occidentalis), a species ubiquitous to cismontane southem Califomia, was observed. Also expected are the Side-blotched Lizard (Uta stansburiana) and Gopher Snake (Pituophis melanoleucus), two other common and widespread species. Birds Observations during the zoological field visit revealed species common to the area, all of which have demonstrated adaptation to thriving in human-altered environments. Representatives include the American Crow (Corvus brachyrhynchos), Mouming Dove (Zenaida macroura), Anna's Hummingbird (Calypte anna), Cassin's Kingbird (Tyrannus vociferans), Bewick's Wren (Thryomanes bewickii). Black Phoebe (Sayornis nigricans), and House Finch (Carpodacus mexicanus). Mammals Only one mammal, the ubiquitous Botta's Pocket Gopher (Thomomys bottae) was observed during the field visits. However the following common and widespread mammals are expected: Califomia Ground Squirrel (Spermophilus beecheyi), Virginia Opossum (Didelphis virginiana), Califomia Mouse (Peromyscus californicus). Deer Mouse (Peromyscus Pacific Southwest Biological Services, Inc. PSBS #7823 maniculatus), Califomia Vole (Microtus californicus). Coyote (Canis latrans). Raccoon (Procyon lotor), and Striped Skunk (Mephitis mephitis). SENSITIVE BIOTIC RESOURCES Sensitive Plants The search ofthe CNDDB for the USGS 7.5' Encinitas and Rancho Santa Fe, Califomia Quadrangles revealed several sensitive plant taxa from the region (Appendix 3). The disturbed conditions on the majority of the site preclude the presence of any of these plants. An additional sensitive species, the Southwestem Spiny Rush (Juncus acutus ssp. leopoldii), does not appear in the CNDDB. This perennial herb is typically found on wet coastal Dunes, in alkaline seeps in meadows, and in marshes and swamps in southem Califomia, Arizona, and perhaps Baja Califomia, Mexico. It is on the Califomia Native Plant Society (CNPS) list of sensitive plants, on list 4 (Plants of Limited Distiibution—A Watch List), with a R-E-D Code of 1-2-1. The CNPS-RED code for this plant is translated as follows: R (Rarity): 1—Rare, but not found in sufficient numbers and distributed widely enough that the potential for extinction is low at this time; E (Endangerment): 2: Endangered in a portion of its range; D (Distribution): 1: More or less widespread outside Califomia. The limited number of these plants observed (approximately 25), indicates that this is a small isolated patch and not of biological significance; therefore no mitigation is recommended for impacts to this species. Sensitive Animals The search of the CNDDB for the USGS 7.5' Encinitas and Rancho Santa Fe, Califomia Quadrangles revealed several sensitive animals from the region (Appendix 4). The disturbed conditions on the majority of the site preclude the presence of any of these animals. WETLAND DELINEATION The parcel has two drainages that join and flow off-site to the west. These areas have defined channels, to which the obligate and facultative wetland vegetation is restricted. In some instances. Willows occur high on the banks of the east-west channel, outside the area of hydrologic influence and hydric soils. The limit of U.S. Army Corps of Engineers (Corps) jurisdiction is the upper edge of the channel banks of both drainages. Lengths of these features are 380 feet of the shorter channel and 840 feet of the longer. The jurisdictional areas of these are 4,560 square feet and 10,080 square feet, respectively. This results in a total area of 0.34 acre (14,640 square feet). The associated Willows outside the Corps jurisdictional area constitute an additional jurisdiction area under the Califomia Department of Fish and Game, adding an additional 0.16-acre. This results in a total habitat area of riparian vegetation of 0.5 acre. HABITAT EVALUATION The majority of the site (6.05 acres) is highly disturbed and virtually devoid of native vegetation and therefore is of almost negligible value as habitat to native fauna and flora. However, the site does contain about 0.5 acre of Southem Willow Scmb and Freshwater Marsh vegetation that contains some isolated Coast Live Oaks and Willow trees. Within the Willow Scmb are pockets of Freshwater Marsh habitats with emergent Cattails. The habitats on the site are virtually landlocked by Camino de los Coches on the south and existing development, a condition existing at least prior to 1995. The on-site stream course continues west, passing again under Camino de los Coches approximately 2,000 feet downstream, past a residential development on the south, into an undeveloped area. Offsite to the west, the stream course Pacific Southwest Biological Services, Inc. PSBS #T823 appears to flow in controlled improved channels and has no biological value. However, stream courses, even in such a limited area, generally support a greater diversity of wildlife than most other habitat types. The small patch of Southwestem Spiny Rush is not considered biologically important because of its small size and isolation. ANTICIPATED PROJECT IMPACTS Loss OF WETLAND HABITATS As presently designed, the project would impact approximately 0.13 acres of Southem Willow Scmb vegetation and 4.96 acres of Disturbed Habitat. The loss of Disturbed Habitat is not considered significant because of the low habitat value. However, the loss of 0.13 acre of Southem Willow Scmb is considered significant unless mitigated. RECOMMENDATIONS TO REDUCE IMPACTS TO A LESS THAN SIGNIFICANT LEVEL Loss OF WETLAND HABITATS A minor change in the grading plan to widen the existing stream course on the northem portion of the site could allow the creation of a treatment wetlands to expand the wetland area and allow for filtering and capture the first flush runoff from the site (Figure 3). This change in the grading plan would also require minor realignment of the planned subterranean drains and headwalls draining the paved portions of the planned improvements. Mitigation for impacts to these jurisdictional drainages would involve excavation of upland areas adjacent to the northem channel to allow for a widening of the floodway and increase in wetland habitat. In concert with the new habitat areas, the discharge sites from the parking lot would be directed so that low flows are treated by the associated wetland vegetation. Permits and/or agreements for disturbance of jurisdictional areas should be obtained prior to grading from the U. S. Army Corps of Engineers and the Califomia Department of Fish and Game.
