1.0 Introduction

Barnett Environmental conducted a Jurisdictional Wetland Delineation & Biological Resources Assessment of the approximately 2.8-acre proposed Eastcliff Estates Residential Development Study Area (APNs 244- 0064-047, 244-0064-050, 244-0064-051) on behalf of Eastcliff Estates 2015, LP. The property is located within Section 10 of Township 9 North, Range 6 East of the USGS 7.5 minute Citrus Heights topographic quadrangle in Fair Oaks, California (Figure 1). It is centered at approximately 38°38’58” North latitude and 121°15’59” West longitude, at 200 feet above mean sea level (msl) within the Lower American River Watershed (Hydrologic Unit Code 18020111). It is a infill parcel, bounded by Fair Oaks Blvd. to the east, and private residences to the north, south and west.

Beyond a U.S. Army Corps of Engineers (1987) jurisdictional delineation of all wetlands and “other waters of the U.S.” within the Study Area, this report:  Identifies and describes the vegetation communities present;  Records all plant and animal species observed during the field survey(s);  Evaluates and identifies sensitive habitats and special status plant and animal species that may occur in the Study Area and could be affected by project activities; and  Provides conclusions and recommendations for mitigating potential adverse impacts to identified resources.

2.0 Methodology

We examined both National Wetland Inventory (Figure 2) and California Aquatic Resources Inventory (Figure 3) maps of the Study Area before delineating wetlands on the ground. We then conducted a jurisdictional wetland delineation of this property in accordance with the 1987 U.S. Army Corps of Engineers Wetlands Delineation Manual and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region. We report these findings in accordance with the November 2001 Minimum Standards for Acceptance of Preliminary Wetlands Delineations notice issued by the Regulatory Branch of the Sacramento District, U.S. Army Corps of Engineers (Corps).

A Level 3, routine onsite determination – as defined in the 1987 Wetland Delineation Manual – evaluated the three parameters that identify and delineate the boundaries of jurisdictional wetlands including: (1) the dominance of wetland vegetation; (2) the presence of hydric soils; and (3) hydrologic conditions that result in periods of inundation or saturation on the surface from flooding or ponding. We also referenced:

1. The Jepson Manual of Higher Plants of California (Hickman, 1993) was used to identify vascular plant species observed during the field delineation. 2. 2. 2012 National List of Plant Species That Occur in Wetlands: California (Region 0) was used to determine the wetland indicator status of plant species observed. 3. 3. On-line NRCS Web Soil Survey and the on-line Field Office Official List of Hydric Soil Map Units for Sacramento County, California were used to identify soil types that occur within the Study Area.

In delineating wetlands within the Study Area on September 10; 2015, involved collection of detailed data on vegetation, soils, and hydrologic site characteristics within the Study Area to identify the upland/wetland boundaries of each identified feature. Besides identifying vascular plants at each sampling location, we also recorded the: 1. Percent dominance by hydrophytic vegetation; 2. Presence/absence of positive hydrologic indicators (e.g., sediment deposits, biotic crust, drainage patterns); and 3. Soils (via soil test pit) to determine composition, matrix color, and the presence of redoximorphic concentrations (e.g., mottles).

Drainages and other features were mapped using a Trimble GeoXHTM with sub-meter accuracy. The perimeter of all features encountered during the field survey was walked to determine their limits.

To assess the Study Area’s biological resources, we first queried the California Department of Fish & Wildlife’s online Natural Diversity Database (RareFind 5) for a list of special status plant and animal species known to occur in the Citrus Heights USGS 7.5’ quadrangle maps (Table 2), reviewed lists of special status species in Sacramento County maintained by the U.S. Fish and Wildlife Service (USFWS 2015), and queried the California Native Plant Society’s online Inventory of Rare & Endangered Plants in California (CNPS 2015).

Barnett biologists also surveyed the Study Area on September 10, 2015 for special status plant and/or wildlife species and their habitats. During this survey, we traversed the entire Study Area on foot and recorded observations of: (1) dominant plant communities, (2) plant and animal species (with emphasis on rare and endangered species) observed or their sign (nests, burrows, tracks, scat) and (3) the suitability of habitat types on site and on immediately adjoining areas to support special status plant and animal species occurring in the surrounding region. We evaluated all habitats in the Study Area for their potential to support special status plants and/or animals and mapped all drainages and other wetland features using a Trimble sub-meter GeoXHTM GPS.

Since the site is heavily grazed and the survey was performed late in the summer, many of the grasses and herbs were dry and in seed. Great effort was taken to find representative plants in protected places, seed heads on the ground, or other means to identify the dominant species in the detailed data plots.

3.0 Existing Conditions

The Study Area is a collection of small ranchette properties on gently sloping terrain north of Archer Avenue and south of Livorna Way in Fair Oaks CA, surrounded by single family residences to the east and agricultural land to the west at approximately 200 feet above mean sea level (Section T9N R6E).

3.1 Soils

The Study Area is comprised solely of Kaseberg-Fiddyment Urban land complex soils with 2-15% slopes (Figure 4). Kaseberg-Fiddyment soils are typically shallow or moderately deep, well-drained soils derived from material weathered from weakly consolidated or moderately consolidated sandstone or siltstone with thin, discontinuous strata of tuff in some areas. These soils are found at elevations of 50 to 280 feet above mean sea level and receive approximately 16 to 22 inches of precipitation annually. They are comprised of approximately 15-28 inches of light yellowish brown sandy loam above with 40 inches of continuous hardpan below that is strongly cemented with silica. Plants in these soils have a rooting depth of four to 18 inches, causing high permeability and water capacity with moderate runoff. In areas where surface soil has been removed by erosion or earthwork, the impermeable layers can be near enough to the surface of the soil to pond water above a perched water table. Consequently, Kaseberg-Fiddyment soils can support localized ponding or saturation to the surface during the rainy season. This mapping unit also recognizes the urban land use and changes to surface conditions for residential and commercial development (Tugel 1980).

3.2 Hydrology

The study area is within the Lower American River watershed (HUC 18020111) in Sacramento County. An unnamed, natural drainage swale crosses the property from northeast to southwest and joins another short drainage swale that runs south from a housing development along the property’s northern boundary. The NE-SW drainage channel joins an unnamed, intermittent “blue line” stream near Mont View Park that is identified on the USGS Citrus Heights 7.5 minute quadrangle. This stream becomes a tributary to the Lower American River at Bannister Park. The approximately 45-acre watershed north of the property contains no identifiable streams and accepts runoff from a mix of residential subdivisions, rural residential property, apartments, and roads. The drainage through the site also exhibits evidence of summer runoff from these mixed residential properties.

3.3 Wetlands & Other Waters of the United States

There is a total of 0.153 acre of jurisdictional wetlands and “other waters of the U.S.” within the Study Area (Table 1 & Figure 5). The 0.018-acre intermittent, NE-SW flowing drainage swale displays no distinct wetland characteristics itself, but widens into a 0.122 acre seasonal wetland before it leaves the property at it southern edge. The natural bed of the drainage swale has been altered by channelization, impoundment of soil and debris above cyclone fencing, past shaping of the drainage by filling or leveling, and enlargement along its lower reach to create a ponded basin. A second (0.008 acre) intermittent drainage enters the parcel’s NW boundary from residential properties to the north. The upper reach of this drainage’s channel has been excavated at some point in the past and is now poorly distinguished, with interrupted bed and bank physiography.

The lack of substantial rains in prior months and the evidence of grazing livestock on the stream banks may be partially responsible for the poor definition of the channel in sections of this lower reach.

Topography, hydric soils, changes in dominant vegetation, and evidence of saturated conditions during the growing season defines the 0.0.122-acre seasonal wetland occurring along the main NE-SW drainage swale through the site. Evidence of saturation was observed by historic flow patterns, elevation of wrack lines along fences, and oxidation mottling in pore channels (there were no living roots) within this feature. Facultative annual grasses – primarily Mediterranean barley (Hordeum marinum) – was the dominant vegetation in this feature, with other facultative upland species – typically Bermuda grass (Cynodon dactylon) – also apparent. Soft chess (Bromus mollis) or a denser cover of Bermuda grass (both facultative upland species) replaces Mediterranean barley outside of the wetland boundary.

We also closely examined two man-made depressions on the property (data points DP-1 and DP-6), but neither of these displayed positive wetland vegetation, soil, or hydrology indicators. One small depression in an old almond orchard on the property showed evidence of saturation at the surface, which this was likely due to artificial irrigation (for livestock watering) from a nearby spigot. A second depression at the bottom of a trenched pit was rimmed with mature and decadent cottonwoods (Populus deltoides) suggesting that at some point in its history it had been ponded or saturated sufficiently long enough for cottonwood seedlings to establish. Mature cottonwoods can have deep roots that allow them persist in non-wetlands after these have dried up or filled in. The trench was not itself vegetated, but was surrounded by partically-browsed thickets of Himalayan blackberry (Rubus armeniaca) – a facultative upland species. We recorded detailed soil data at the lowest point in this trench – where no vegetation was present – and observed some evidence of an incipient mollic horizon, but none of long-duration saturation or ponding. The mollic horizon may have developed from a long accumulation of organic matter blown into the trench or leaf litter falling from the canopy of deciduous cottonwood trees. The bottom of the trench is excavated well below the mapped soil surface and no longer displayed characteristics of Kaseburg or Fiddyment

Eastcliff Estates 9 November 10, 2015

soils or a well-developed impervious horizon. Instead, the incipient soil in the bottom of the trench is developing in partially consolidated and much more porous sand, silt, and gravel of the Turlock Lake Formation (Wagner et al. 1981).

Lastly, a man-made ditch (0.005 acre) from the mouth of the above trench to the lower reach of the seasonal wetland described above, is a feature constructed at the property’s western boundary to accept runoff from a culvert at the eastern end of the Eastcliff Avenue extension to the west. The ditch does not appear to drain more than the local area of the roadbed, is clearly not in a natural drainage, and is likely ephemeral, flowing only briefly after extended precipitation events.

3.4 Vegetation Communities

The Eastcliff Estates property is vegetated with a mix of introduced grasses and herbs in dryland pasture, including soft chess (Bromus hordeaceous), ripgut brome (Bromus diandrus), and wild oats (Avena barbata), along with common perennials such as Bermuda grass (Cynodon dactylon), cheeseweed (Malva parviflora), burr clover (Medicago polymorpha) and bull thistle (Cirsium vulgare). The low-lying areas of the site support hydrophytic herbs, including tall flat sedge (Cyperus eragrostis), curly dock (Rumex crispus), Dallis grass (Paspalum dilatatum), and velvet grass (Holcus lanatus). Willows (Salix laevigata, S. exigua, and S gooddingii) are found along the drainages and seasonal pond. Native valley and interior live oaks (Quercus lobata and Q. wislizenii) provide an open woodland/savannah cover along with horticultural trees in derelict orchards or ornamental plantings throughout the property that include fig, persimmon, palm, almond, pear and various ornamental perennials.

3.5 Wildlife and Their Habitats

The approximately three-acre Study Area supports a typical, though highly disturbed, Central Valley oak savannah habitat that is currently used for livestock (e.g. goat, sheep) pasture, but previously supported a small almond orchard that is no longer managed. There are numerous ornamental trees and perennial shrubs surrounding extant residences in the northern and southeastern portions of the property and considerable evidence of historic drainage manipulation and current, artificial watering to support the ongoing livestock grazing. Consequently, there is little natural wildlife habitat remaining on this site and none appropriate for regional special status species, beyond seasonal raptor nesting opportunities in the onsite oaks and cottonwood.

We observed little in the way of existing wildlife on this property, however, apart from the ubiquitous species normally encountered on urban/suburban and highly disturbed Valley sites, which include: western fence lizard (Sceloporus occidentalis), black-tailed jackrabbit (Lepus californicus), turkey vulture (Cathartes aura), mockingbird (Mimus polyglottis), scrub jay (Aphelocoma coerulescens), house finch (Carpodacus mexicanus), white-crowned sparrow (Zonotrichia leucophrys), and mourning dove (Zenaida macroura).

4.0 Special Status Species

Special status species are those that fall into one or more of the following categories:  Listed as endangered or threatened under the federal Endangered Species Act (or formally proposed for listing),  Listed as endangered or threatened under the California Endangered Species Act (or proposed for listing),  Designated a Species of Concern by the Sacramento District of the U.S. Fish and Wildlife Service,  Designated as rare, protected, or fully protected pursuant to California Fish and Game Code,  Designated a Species of Concern by the California Department of Fish and Game,  Defined as rare or endangered under the California Environmental Quality Act (CEQA), or  Occurring on List 1 or 2 maintained by the California Native Plant Society.

Six plant species – Soft salty bird’s-beak (Chloropyron molle ssp. Molle), boggs lake hedge hyssop (Gratiola heterosepala), Mason’s lilaeopsis (Lilaeopsis masonii), Antioch dunes evening-primros (Oenothera deltoids ssp. Howellii), slender Orcutt grass (Orcuttia tenuis), Sacramento orcutt grass (Orcuttia viscida) – could potentially occur within the Study Area or vicinity. Ten (10) special status animal species could also potentially occur in this region, including the: valley elderberry longhorn beetle (VELB; Desmocerus californicus dimorphus), vernal pool fairy shrimp (Branchinecta lynchi), vernal pool tadpole shrimp (Lepidurus packardi), California tiger salamander (Amboystoma californiense), giant garter snake (Thamnophis gigas), western yellow-billed cuckoo (Coccyzus americanus occidentalis), California black rail (Laterallus jamaicensis coturniculus), bank swallow, (Riparia riparia), swainson’s hawk (Buteo swainsoni), least bell’s vireo (Viero bellii pusillus). A query of the California Natural Diversity Database (Rarefind) resulted in no records of any of these species within or immediately adjacent to the Eastcliff Estates Study Area. While the species listed above may potentially occupy the Study Area vicinity, based on habitat requirements, historic and ongoing disturbance of the site itself likely precludes their presence in this area (Table 2). We observed no special-status plant or wildlife species or bird nests in the Study Area during our field survey and could identify no habitat for any federal- or state-listed species. Because there are no elderberry (Sambucus spp.) shrubs on the property, there is no habitat for Valley elderberry longhorn beetle (Desmocerus californicus dimorphus). There is likewise no habitat for the federally listed vernal pool fairy shrimp (Branchinecta lynchi) or vernal pool tadpole shrimp (Lepidurus packardi). And, while perennial waters in the Sacramento region can support giant garter snakes (Thamnophis gigas), none have been found this far east and the drainages within the property are too dry in the summer to support this aquatic snake. There is only very marginal nesting habitat for birds of prey and migratory birds. It is unlikely that birds of prey and other migratory birds would build a nest in the trees on the property because they are in an area of high human disturbance and are not within or adjacent to good foraging habitat. While we performed our field survey of the site outside of the nesting season for most birds of prey and migratory birds, we found no nest structures in any of the trees within or adjacent to the Study Area.

4.1 Critical Habitat for Special Status Species

The Federal Endangered Species Act (FESA) requires the federal government to designate critical habitat for any listed species. Critical habitat is defined as: (1) specific areas within the geographical area occupied by the species at the time of listing, if they contain physical or biological features essential to conservation, and those features may require special management considerations or protection; and (2) specific areas outside the geographical area occupied by the species if the agency determines that the area itself is essential for conservation. There is no designated critical habitat within the Study Area.

5. Slender orcutt grass – (Orcuttia tenuis; CNPS List 1B.1) is an annual grass from the grass family (Poaceae). This species is federally listed as threated and a California endangered species. Additionally, it is on the CNPS List 1B. This grass species generally consists of 1 main stem that is six inches long with long basal leaves. The inflorescence comprised of a spikelet 3 inches in length containing 3 to 6 glumes. It blooms from May to October within interior dunes at elevations ranging from 650 to 3, 600 feet. It is threatened by agriculture, residential development, grazing, recreational activities, and non-native plants. This species was not observed during the field survey conducted in September 2015. In addition, results of a CNDDB search revealed no recorded occurrences of slender orcutt grass within two miles of the project site (Figure 6).

6. Sacramento orcutt grass – (Orcuttia viscida; CNPS List 1B.1) is an annual herb from the grass family (Poaceae). This species is both federally and state listed as endangered. This grass species is small, hairy, aromatic, forming sticky glandular tufts up to 3 to 5 inches high. The inflorescence is small, crowded cluster of spikelets with awned tips that curve outward at maturity, giving the spikes a bristly appearance. This species is found within vernal pools and blooms from April to July at elevations ranging from 100 to 300 feet. It is threatened by agriculture, urbanization, overgrazing, vehicles, and non-native plants. This species was not observed during the field survey conducted in September 2015. In addition, results of a CNDDB search revealed no recorded occurrences of Sacramento orcutt grass within two miles of the project site (Figure 6).

4.3 Special Status Wildlife

Federally Listed Species

A total of five federally listed animal species have the potential to occur, but are not know to occur within the Study Area or surrounding vicinity (CNDDB, Table 2). These include:

1. Valley elderberry longhorn beetle (Desmocerus californicus dimorphus) – This beetle is listed as threatened by the U. S. Fish and Wildlife Service. Live blue elderberry shrubs (Sambucus mexicana) are this borer’s exclusive host plant. Elderberry shrubs are primarily associated with riparian corridors and moist oak woodlands at elevations below 2,500 feet. Exit holes made by the emerging adults are distinctive small oval openings (approx. ¼-inch width). Adults eat elderberry foliage until about June when they mate. Females lay eggs in crevices in the bark before dying a short time later. Upon hatching the larvae then begin to tunnel into the tree where they spend 1-2 years eating the interior wood, which is their sole food source. No live blue elderberry scrubs were observed within the Study Area therefore it is unlikely that valley elderberry longhorn beetles occur here. No elderberry shrubs were observed during the September 2015 field survey. The CNDDB (Figure 6) contains two VELB occurrence record approximately two miles southeast of the Study Area.

2. Vernal pool tadpole shrimp (Lepidurus packardi) – This crustacean, listed as endangered by the U. S. Fish and Wildlife Service, is generally five centimeters long and occurs in deeper vernal pools with clear-to-turbid water. Their eggs are drought-tolerant cysts that hatch within three weeks of a pool or swale filling with water. The adults mature around day 38 and are able to reproduce at day 54. The new eggs encyst and bury themselves in the muddy soil. Two seasonal wetlands and a pool were found within the Study Area and could potentially provide suitable habitat for tadpole shrimp, but are unlikely do so as none appear deep enough to support the species. The actual presence or absence of

Eastcliff Estates 17 November 10, 2015

tadpole shrimp cannot be determined, however, unless or until FWS protocol-level surveys are conducted. No vernal pool tadpole shrimp were observed the field survey conducted in September 2015. In addition, results of a CNDDB search revealed no recorded occurrences of tadpole shrimp within two miles of the project site (Figure 6).

3. Vernal pool fairy shrimp (Branchinecta lynchi) – This crustacean, listed as threatened by the U. S. Fish and Wildlife Service, ranges in size from 0.43 to 0.98 inches and occurs in vernal pools, seasonal wetlands and wetland swales through most of the Central Valley to Tulare County. The habitats can be grass- or mud-bottomed, with clear to tea-colored water, and can be underlain by claypan or basalt- flow hardpan in grasslands. Vernal pool fairy shrimp have a lifespan of two months, from January to early March. Females lay drought-resistant eggs that embed into the soil and hatch the next winter when the pools refill. Though no fairy shrimp were observed during the field survey conducted in September 2015, their presence or absence cannot be determined without FWS-protocol surveys. However, a CNDDB query (Figure 6) revealed that there was a single recorded occurrences of fairy shrimp within a two mile radius of the Study Area.

4. California tiger salamander (Amboystoma californiense) – This amphibian is listed as threatened by the U. S. Fish and Wildlife Service. It is a relatively large salamander that can grow up to seven to eight inches in length and can be found in a variety of habitats that include riparian and cismontane woodland, valley and foothill grasslands, meadows, and wetlands at elevations up to 3000 feet. Adults spend the majority of their time in underground burrows excavated by ground squirrels, jackrabbits or gophers. Tiger salamanders breed and lay eggs primarily in vernal pools and other temporary rainwater ponds following relatively warm rains in November to February (Shaffer and Fisher 1991). They sometimes use permanent human-made ponds if predatory fishes are absent, but streams are rarely used for reproduction. While no California tiger salamanders were observed during the September 2015 field survey, the CNDDB contains no recorded occurrences of California tiger salamander within two miles of the Study Area (Figure 6). A definitive determination of the species’ presence or absence would require FWS-protocol level surveys.

5. Yellow-billed cuckoo (Coccyzus americanus occidentalis) – The yellow-billed cuckoo is a federally- listed threatened species. This species has a flat head, thin body, a very long tail, and yellow bill. Yellow-billed cuckoos are warm brown on top, white underneath, with large white spots on the underside of its tail. This species is found in woodland areas with dense cover including low, scrubby, vegetation, overgrown orchards, abandoned farmland, and dense thickets along streams and marshes. Their primary diet consist of caterpillars, however they also consume beetles, ants, spiders, small wild fruits, and seeds. Cuckoos may respond to available food supplies rather than a set season to begin breeding. This species constructs their nests from loose sticks within a variety of trees which include oaks, beech, hawthorn, and ash. Nests consists of a flat, oblong platform reaching up to five inches deep and eight inches in diameter at a height ranging from 3 to 90 feet off the ground. Yellow-billed cuckoos can lay up to five eggs with an incubation period of 9 to 11 days. Fledging can occur as little as eight days after hatching. This species is threatened by encroachment of farmland and residential development. While no yellow-billed cuckoos were observed during the September 2015 field survey, the CNDDB contains no recorded occurrences of yellow-billed cuckoos within two miles of the Study Area (Figure 6).

Eastcliff Estates 18 November 10, 2015

6. Least Bell’s vireo (Vireo bellii pusillus) – Least bell’s vireo is a federally-listed endangered species. This is a small North American songbird approximately 4.75 to 5 inches in length, dull olive-gray above and whitish underneath, with a faint white eye ring and wing bars. Bell’s vireo are found in dense, low, shrubby vegetation within riparian areas, brushy fields, young second-growth forest or woodland, scrub oak, coastal chaparral, and mesquite bushlands, often near water in arid regions. Their diet consist of insects and spiders. Nest are usually suspended from forks of low branches of small trees or shrubs. They have an open bag or basket-like appearance and constructed from grass, straw-like stems, plant fibers, small skeletonized leaves, paper, and strips of bark fastened with spider silk; lined almost invariably with fine, brown or yellow grass stems. Bell’s vireo breed during the summer and tend to have three to five eggs at a time. This species is threatened by the loss of riparian habitat and brood parasitism by the brown-headed cowbird (Molothrus ater). While no least Bell’s vireo were observed during the September 2015 field survey, the CNDDB contains no recorded occurrences of least Bell’s vireo within two miles of the Study Area (Figure 6). A definitive determination of the species’ presence or absence would require FWS-protocol level surveys.

7. Giant garter snake (Thamnophis gigas) – The giant garter snake is a federally-listed threatened species found from sea level to about 160 feet in perennial waters or their immediate environs, but will also inhabit temporary water such as sloughs, irrigation canals, drainage ditches, and flooded rice fields. They show a preference for the slower-flowing sloughs that are not found along major rivers. Giant garter snake habitat is typically devoid of a dense tree canopy and usually contains tule, cattail, blackberry, mustard, various thistles and annual and perennial grasses (CNDDB 2007). They are typically observed above ground from April till October and spend the remainder of the year in underground winter burrows. By April 15 most of the snakes are actively foraging. Their diet consists of aquatic prey such as fish, amphibians, and of introduced species such as carp, mosquitofish, and bullfrogs. By early October, foraging is sporadic and dependent on good weather and most giant garter snakes are underground by the first of November, where they remain until spring. Breeding occurs soon after emergence in the spring and females bear live young from July through early September. Giant garter snakes are typically diurnal, although they have occasionally been observed feeding as during evening hours. During the spring, juvenile giant garter snakes are frequently active in the morning, while adults are most often seen basking during midday and the afternoon. No giant garter snakes were observed during the September 2015 field survey. The CNDDB contains no recorded occurrences of the species within two miles of the Study Area (Figure 6).

California (State) Listed Species

State listed species are plants and animals that are legally protected under the California Endangered Species Act (CESA). Only two such species have the potential to occur in the Study Area:

1. Swainson’s hawk (Buteo swainsoni) – The Swainson’s hawk is a California threatened species. It is a large (1.75 - 2 pounds), broad-winged bird-of-prey (raptor) that frequents open country. It is a long distance migrator that nests in the Central Valley from March 1 to September 15 and over-winters in Mexico or South America. This hawk forages almost exclusively in agricultural row-crops and grasslands. Its favored prey is voles and small rodents that are more readily available in suitable densities on agricultural lands. Unlike some other local raptors, urban areas or dense vegetation do not provide suitable foraging habitat for this hawk. Sacramento, Yolo, and San Joaquin Counties support most of the Central Valley Swainson’s hawk breeding population. Narrow riparian systems and

Eastcliff Estates 19 November 10, 2015

scattered Valley oak trees, combined with suitable agricultural foraging habitat, provide high-quality habitat conditions in Sacramento County, where an estimated 100 pairs nest. Swainson’s hawks are monogamous and actively nest from March through July. Nests of twigs and grasses are constructed in isolated trees or bushes, shelterbelts, riparian groves, or abandoned homesteads, approximately nine to 15 ft above the ground in cottonwood, poplar, oak and the occasional pine tree in the Central Valley. The incubation period is 34 to 35 days, with fledging at about 38 to 46 days. No Swainson’s hawks were observed during the field survey conducted in September 2015, but they are likely in Mexico or South America at this time. In addition, results of a CNDDB search revealed no recorded occurrences of swainson’s hawk within two miles of the project site (Figure 6).

2. California black rail (Laterallus jamaicensis coturniculus) – The California black rail is a California threatened species. This species is very small approximately four to six inches in length and weighs about an ounce. Black rails are blackish above, with white speckling, chestnut nape, and greyish underneath with white barring on flanks. Habitats consists of salt marshes, shallow freshwater marshes, wet meadows, and flooded grassy vegetation. Their diet primarily consist of small invertebrates and seeds. Black rails build well concealed nests on the ground, and often under dense vegetation. Breeding occurs during the summer and they usually lay between five to eight eggs per clutch. While no California black rails were observed during the September 2015 field survey, the CNDDB contains no recorded occurrences of black rails within two miles of the Study Area (Figure 6).

3. Bank swallow (Riparia riparia) – The bank swallow is a California threatened species. This species has a small and slender build and approximately four to 6 inches long. Bank swallows are white underneath, brown on top, with a dark band across their chest and extending down the middle of their abdomen. They are found in low areas along rivers, streams, ocean coast, or reservoirs. Their territories usually include vertical cliffs or banks where they nest in colonies of 10 to 2,000 nest. Bank swallow’s feed while flying therefore their diet consist of flying insect such as bees, wasps, butterflies, and moths. This species builds nest, often in large colonies, in vertical banks and bluffs consisting of loose soils so they can create borrows. The nests are often constructed out of straw, grasses, leaves, or roots. Breeding occurs during the summer and the female lays two to six eggs per clutch. Incubation period ranges from 13 to 16 days with a fledging in approximately four weeks after hatching. While no bank swallows were observed during the September 2015 field survey, the CNDDB contains records of three occurrences of bank swallow within two miles of the Study Area (Figure 6).

Though these species could potentially use the Study Area vicinity for some portion(s) of their life cycle, repeated field surveys found no indication of their use of the proposed project area itself. The historic and ongoing disturbance of the site likely precludes their presence in this area

Eastcliff Estates 20 November 10, 2015 5.0 Conclusion

1) There are 0.153 acres of wetlands and “other waters of the United States” within the project area. A Section 404 permit from the U.S. Army Corps of Engineers and a Section 401 water quality certification from the Regional Water Quality Control Board may be required if there are any activities affecting these features. A section 404 Nationwide Permit (29) will be required if the project results in impacts of less than 0.5 acre to wetlands and “other waters of the United States.

2) A query of the California Natural Diversity Database (Rarefind) resulted in no records of any species of special concern within or immediately adjacent to the Eastcliff Estates project area. While the species listed in Table 2 may potentially occupy the site based on habitat requirements, historic and ongoing disturbance may preclude presence of these species. However, in order to confirm their presence or absence a protocol-level survey must be conducted.
