It requires exposed sandy streamsides with stable terraces for burrowing with scattered vegetation for shelter, and areas of quiet water or pools free of predatory fishes with sandy or gravel bottoms without silt for breeding. The arroyo toad is listed as a federally endangered species and is designated as a California Species of Special Concern. There is one historical record within five miles of the project site. Although there is no suitable breeding habitat on the project site, there is suitable foraging and sheltering habitat for this species is in the coastal sage scrub community and dry wash on and adjacent to the project site.
Western Spadefoot
Western spadefoot is an Anuran amphibian in the family Pelobatidae. This species prefers open areas with sandy or gravelly soils in a variety of habitats including mixed woodlands, grasslands, coastal sage scrub, chaparral, sandy washes, lowlands, river floodplains, alluvial fans, playas, alkali flats, foothills, and mountains. Western spadefoot breed in seasonally ephemeral pools of water that do not contain bullfrogs, fish, or crayfish. Breeding sites include vernal pools and other temporary rain pools, cattle tanks, and occasionally in pools within intermittent streams. Suitable breeding pools must support standing water for at least 4 to 11 weeks for the larval stages of this species to transform. Typically, the pools are turbid with little or no cover. Western spadefoot are nocturnal and almost completely terrestrial, entering water only to breed. They burrow underground using the hardened spades on their hind feet and can remain buried underground for most of the year, emerging during periods of rain for breeding. Breeding may take place from January to May, peaking in February and March, but may breed at any time of the year if conditions are favorable. Western spadefoot eat a variety of invertebrates, including adult beetles, larval and adult moths, crickets, flies, ants, and earthworms, and can consume
enough in several weeks to survive the long period of underground dormancy. Western spadefoot is designated as a California Species of Special Concern. There is one recent record within five miles of the project site and two historical records between five and ten miles from the project site. Although there is no suitable breeding habitat on the project site, there is suitable foraging and sheltering habitat for this species is in the coastal sage scrub community and dry wash on and adjacent to the project site.

The southern California legless lizard species is designated as a California Special Species of Concern. There are three recent and one historical records within five miles of the project site and seven recent and six historical records between five and ten miles from the project site. Suitable habitat for this species is in the coastal sage scrub community and dry wash on and adjacent to the project site.
California Glossy Snake
The California glossy snake is a snake in the family Colubridae. This species is found in areas of rocky washes and loose, sandy soils and for burrowing in desert scrub grassland, coastal sage and Riversidean alluvial fan sage scrub, and chaparral habitats.

It feeds on small invertebrates, especially spiders, scorpions, centipedes, and termites, as well as other small lizards. The San Diegan tiger whiptail is designated as a California Species of Special Concern. There is one recent record within five miles of the project site and one recent record between five and ten miles from the project site. This species was observed on the project site in ruderal habitat adjacent to the dirt road and orchard and, therefore, is considered to be present on the project site. A population of this species likely occurs in the coastal sage scrub community and dry wash on and adjacent to the project site.
Coast Horned Lizard
Coast horned lizard is a lizard in the family Phrynosomatidae. This species occurs primarily in western California, where it frequents a wide variety of habitats, most commonly in grasslands, coniferous forests, woodlands, and chaparral, with open areas and patches of loose soil. This species requires open areas for sunning, bushes for cover, patches of loose soil for burial, and abundant supply of ants and other insects. Populations of this species are threatened by habitat destruction from human
development and agriculture, and the spread of non-native ants, such as Argentine ant (Linepithema humile) which displace the native ant food source. Before commercial collecting was banned in 1981, this lizard was extensively exploited by the pet trade and the curio trade. The coast horned lizard is designated as a Special Species of Concern. There are two historical records within five miles of the project site and eight historical records between five and ten miles from the project site. Suitable habitat for this species is in the coastal sage scrub community and dry wash on and adjacent to the project site.

The coastal California gnatcatcher is listed as a federally threatened species and is designated as a California Species of Special Concern. Their nests are protected by the MBTA and California FGC pertaining to native nesting avian species. There are six historical records within five miles of the project site and one recent and five historical records between five and ten miles from the project site. Suitable habitat for this species is in the coastal sage scrub community north of the project site where the scrub community is relatively open.
San Bernardino Kangaroo Rat
The San Bernardino kangaroo rat (SBKR) is one of three subspecies of the Merriam’s kangaroo rat (Dipodomys merriami). The Merriam’s kangaroo rat is a widespread species that can be found from the inland valleys to the deserts of southern California. The subspecies known as SBKR, however, is confined to inland valley scrub communities, and more particularly, to scrub communities occurring along rivers, streams and drainages. Most of these systems have been historically altered as a result of flood control efforts and the increased use of river resources, including mining, off-road vehicle use and road and housing development. This increased use of river resources has resulted in a reduction in both the amount and quality of habitat available for SBKR. The San Bernadino kangaroo rat is listed as a federally endangered species and a candidate for listing as a California endangered species. The species is also designated as a California Species of Special Concern. There are two recent and two historical records within five miles of the project site and three recent and eleven historical records between five and ten miles from the project site. Suitable habitat for this species is in the coastal sage scrub community and dry wash on and adjacent to the project site.

This species occurs in open, semi-arid to arid habitats, including conifer and deciduous woodlands, coastal scrub, grasslands, chaparral and roosts in crevices in cliff faces, high buildings, trees, and tunnels. It forages primarily on moths, but also takes crickets and katydids. The western mastiff bat is designated as a California Species of Special Concern. There is one historical record within five miles of the project site and three historical records between five and ten miles from the project site. Suitable habitat for this species is in the coastal sage scrub and southern California black walnut woodland communities on and adjacent to the project site.

The project site is currently undeveloped. The proposed Almond Street Extension Project (proposed project) would extend Almond Street approximately 900 feet from Carnelian Street and Via Verde Street. The proposed project would provide an additional east-west street connection north of I-210, improving traffic circulation and public safety access in support of the goals of the General Plan. The limits of disturbance include a road width of 44 feet wide from curb to curb, with 11 feet of parkway at each side, and the total right-of-way width would be 66 feet wide.
