Loggerhead Shrike
The loggerhead shrike (Lanius ludovicianus) is not listed pursuant to either the California or federal ESAs; but is considered a bird of conservation concern by the USFWS and a SSC by the CDFW. Loggerhead shrikes nest throughout California except the northwestern corner, montane forests, and high deserts (Small 1994). Loggerhead shrikes nest in small trees and shrubs in open country with short vegetation such as pastures, old orchards, mowed roadsides, cemeteries, golf courses, agricultural fields, riparian areas, and open woodlands (Yosef 1996). The nesting season extends from March through July.

There are no documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). Loggerhead shrike is a SSHCP Covered Species, and the grassland within the Study Area provides suitable nesting and foraging habitat for this species, and the aquatic features provide suitable foraging habitat, according to SSHCP Modeled Species Habitat. Loggerhead shrike has potential to occur within the Study Area.

Merlin
The Merlin (Falco columbarius) is not listed pursuant to either the California or federal ESAs, but is a CDFW “watch list” species and currently tracked in the CNDDB. This falcon breeds in Canada and Alaska and occurs in California as a migrant and during the non-breeding season (September through April).

Foraging habitat in winter includes open forests, grasslands, and tidal flats (Warkentin et al. 2005). Merlin do not nest in the region but may occasionally forage within grassland and woodland communities onsite during winter or migration.

There is one documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). The grassland within the Study Area provides suitable wintering habitat for this species.

Merlin has potential to occur within the Study Area.

Northern Harrier
The northern harrier (Circus cyaneus) is not listed pursuant to either the California or federal ESAs; however, it is considered to be a SSC by the CDFW. This species is known to nest within the Central Valley, along the Pacific Coast, and in northeastern California. The northern harrier is a ground nesting species, and typically nests in emergent wetland/marsh, open grasslands, or savannah communities usually in areas with dense vegetation (Smith et al. 2011). Foraging occurs within a variety of open environments such as marshes, agricultural fields, and grasslands. Nesting occurs during April through September.

There are no documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). Northern harrier is a SSHCP Covered Species, and the grassland within the Study Area provides suitable nesting and foraging habitat for this species, and the aquatic features provide suitable foraging habitat, according to SSHCP Modeled Species Habitat. Northern harrier has potential to occur within the Study Area.

Swainson’s Hawk
The Swainson’s hawk (Buteo swainsoni) is listed as a threatened species pursuant to the California ESA.

This species nests in North America (Canada, western United States, and Mexico) and typically winters from South America north to Mexico. However, a small population has been observed wintering in the Sacramento-San Joaquin River Delta (Bechard et al. 2010). In California, the nesting season for Swainson’s hawk ranges from mid-March to late August. Swainson’s hawks nest within tall trees in a variety of wooded communities including riparian, oak woodland, roadside landscape corridors, urban areas, and agricultural areas, among others. Foraging habitat includes open grassland, savannah, low-cover row crop fields, and livestock pastures. In the Central Valley, Swainson’s hawks typically feed on a combination of California vole (Microtus californicus), California ground squirrel (Spermophilus beecheyi), ring-necked pheasant (Phasianus colchicus), many passerine birds, and grasshoppers (Melanopulus species).

Swainson’s hawks are opportunistic foragers and will readily forage in association with agricultural mowing, harvesting, disking, and irrigating (Estep 1989). The removal of vegetative cover by such farming activities results in more readily available prey items for this species.

There are seven documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). Swainson’s hawk is a SSHCP Covered Species, and the grassland and aquatic areas within the Study Area provide suitable foraging habitat for this species according to SSHCP Modeled Species Habitat. In addition, a preliminary survey of potential habitat found several trees within the Survey Area and survey buffers that represent potential nesting habitat. Swainson’s hawk has potential to occur within the Study Area.

Tricolored Blackbird
The tricolored blackbird (Agelaius tricolor) is listed as threatened pursuant to the California ESA. In addition, it is currently considered a USFWS bird of conservation concern and a CDFW SSC. This colonial nesting species is distributed widely throughout the Central Valley, Coast Range, and into Oregon, Washington, Nevada, and Baja California (Meese et al. 2014). Tricolored blackbirdnest in colonies that can range from several pairs to several thousand pairs, depending on prey availability, the presence of predators, or level of human disturbance. Tricolored blackbird nesting habitat includes emergent marsh, riparian woodland/scrub, blackberry thickets, densely vegetated agricultural and idle fields (e.g., wheat, triticale, safflower, fava bean fields, thistle, mustard, cane, and fiddleneck), usually with some nearby standing water or ground saturation (Meese et al. 2014). They feed mainly on grasshoppers during the breeding season, but may also forage upon a variety of other insects, grains, and seeds in open grasslands, wetlands, feedlots, dairies, and agricultural fields (Meese et al. 2014). The nesting season is generally from March through August.

There are 10 documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). Tricolored blackbird is a SSHCP Covered Species, and the grassland within the Study Area provides suitable nesting and foraging habitat for this species, and the aquatic features provide suitable foraging habitat, according to SSHCP Modeled Species Habitat. In addition, a preliminary survey of potential habitat documented evidence of previous tricolored blackbird nesting within patches of bull ITEM 11.1. ATTACHMENT 4

Biological Resources Assessment for The Preserve Development ECORP Consulting, Inc.

The Preserve 38 July 27, 20212018-205
thistle (Cirsium vulgare) in the central portion of the site, and a small area of riparian habitat along Morrison Creek was also determined to represent potential nesting habitat (Attachment C). However, tricolored blackbirds were not observed nesting during a site visit on June 13, 2019. This species is nomadic and may or may not return to the site. Tricolored blackbirds are considered to be present within the Study Area.

White-Tailed Kite
White-tailed kite (Elanus leucurus) is not listed pursuant to either the California or federal ESAs; however, the species is fully protected pursuant to Section 3511 of the California Fish and Game Code. This species is a common resident in the Central Valley and the entire length of the California coast, and all areas up to the Sierra Nevada foothills and southeastern deserts (Dunk 1995). In northern California, white-tailed kite nesting occurs from March through early August, with nesting activity peaking from March through June.

Nesting occurs in trees within riparian, oak woodland, savannah, and agricultural communities that are near foraging areas such as low elevation grasslands, agricultural, meadows, farmlands, savannahs, and emergent wetlands (Dunk 1995).

There are five documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). White-tailed kite is a SSHCP Covered Species, and the grassland and aquatic areas within the Study Area provide suitable foraging habitat for this species according to SSHCP Modeled Species Habitat. White-tailed kite has potential to occur within the Study Area.

Yellow-Billed Magpie
The yellow-billed magpie (Pica nuttalli) is not listed pursuant to either the California or federal ESAs but is considered a USFWS bird of conservation concern. This endemic species is a yearlong resident of the Central Valley and Coast Ranges from San Francisco Bay to Santa Barbara County. Yellow-billed magpies build large, bulky nests in trees in a variety of open woodland habitats, typically near grassland, pastures or cropland. Nest building begins in late-January to mid-February, which may take up to 6-8 weeks to complete, with eggs laid during April-May, and fledging during May-June (Koenig and Reynolds 2009).

The young leave the nest at about 30 days after hatching (Koenig and Reynolds 2009). Yellow-billed magpies are highly susceptible to West Nile Virus, which may have been the cause of death to thousands of magpies during 2004-2006 (Koenig and Reynolds 2009).

There are no documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). However, the grassland and trees within the Study Area provide suitable nesting habitat for this species. Yellow-billed magpie has potential to occur within the Study Area.

4.5.6 Mammals
Two Covered Species mammals were determined to have potential to occur within the Study Area based on SSHCP Modeled Species Habitat, and one other species was identified as having the potential to occur within the Study Area based on the literature review (Attachment G). Brief descriptions of these species are presented below.

American Badger
The American badger (Taxidea taxus) is not listed pursuant to either the federal or California ESAs; however, this species is considered a SSC by CDFW. American badger historically ranged throughout much of the state, except in humid coastal forests. American badgers were once numerous in the Central Valley; however, populations now occur in low numbers in the surrounding peripheral parts of the Central Valley and in the adjacent lowlands of eastern Monterey, San Benito, and San Luis Obispo counties (Williams 1986). American badgers occupy a variety of habitats, including grasslands and savannas. The principal requirements seem to be significant food supply, friable soils, and relatively open, uncultivated ground (Williams 1986).

There is one documented CNDDB occurrence of this species located within five miles of the Study Area (CDFW 2018a). American badger is a SSHCP Covered Species, and the grassland and wetland areas within the Study Area provide suitable foraging habitat for this species according to SSHCP Modeled Species Habitat. American badger has potential to occur within the Study Area.

Pallid Bat
The pallid bat (Antrozous pallidus) is not listed pursuant to either the California or federal ESAs; however, this species is considered a SSC by CDFW. The pallid bat is a large, light-colored bat with long, prominent ears and pink, brown, or grey wing and tail membranes. This species ranges throughout North America from the interior of British Columbia, south to Mexico, and east to Texas. The pallid bat inhabits low elevation (below 6,000 ft) rocky arid deserts and canyonlands, shrub-steppe grasslands, karst formations, and higher elevation coniferous forest (above 7,000 ft). This species roosts alone or in groups in the crevices of rocky outcrops and cliffs, caves, mines, trees, and in various human structures such as bridges, and barns. Pallid bats are feeding generalists that glean a variety of arthropod prey from surfaces as well as capturing insects on the wing. Foraging occurs over grasslands, oak savannahs, ponderosa pine forests, talus slopes, gravel roads, lava flows, fruit orchards, and vineyards. Although this species utilizes echolocation to locate prey, often they use only passive acoustic cues. This species is not thought to migrate long distances between summer and winter sites (WBWG 2017).

There are no documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). However, some of the structures within the Study Area represent potential hibernacula (see Attachment C). Pallid bat has potential to occur within the Study Area.

Western Red Bat
The western red bat (Lasiurus blossevillii) is not listed pursuant to either the California or federal Endangered Species Acts; however, this species is considered a SSC by CDFW. The western red bat is easily distinguished from other western bat species by its distinctive red coloration. This species is broadly distributed, its range extending from southern British Columbia in Canada through Argentina and Chile in South America, and including much of the western United States. This solitary species day roosts primarily in the foliage of trees or shrubs in edge habitats bordering streams or open fields, in orchards, and occasionally urban areas. They may be associated with intact riparian habitat, especially with willows, ITEM 11.1. ATTACHMENT 4

Biological Resources Assessment for The Preserve Development ECORP Consulting, Inc.

The Preserve 40 July 27, 20212018-205
cottonwoods, and sycamores. This species may occasionally utilize caves for roosting as well. They feed on a variety of insects, and generally begin to forage one to two hours after sunset. This species is considered highly migratory; however, the timing of migration and the summer ranges of males and females may be different. Winter behavior of this species is poorly understood (WBWG 2017).

There are no documented CNDDB occurrences of this species located within five miles of the Study Area (CDFW 2018a). However, western red bat is a SSHCP Covered Species. The grassland and wetland areas within the Study Area provide suitable foraging habitat. The Raymer Way offsite contains roostingforaging habitat for this species according to SSHCP Modeled Species Habitat; however, site assessment did not find evidence of potential roosting habitat within the Raymer Way Offsite (Attachment C). A preliminary survey of potential habitat identified some of the trees with cavities along Morrison Creek as potential hibernacula (Attachment C). Western red bat has potential to occur within the Study Area.

4.6 Wildlife Movement/Corridors
The Study Area is located in an undeveloped area within the limits of the City of Rancho Cordova, roughly four miles south of U.S. Highway 50. The Study Area does not fall within an Essential Habitat Connectivity area mapped by the CDFW (CDFW 2018a). The upper reach of Morrison Creek runs along the northern boundary of the Study Area. Though Morrison Creek is ephemeral, the permanently ponded open waters and the small patches of riparian habitat along the creek may represent a marginal wildlife movement corridor; however, this area lies outside of the Study Area with the exception of the Morrison Creek Offsite.

4.7 Sensitive Natural Communities
Five sensitive natural communities were initially identified as having the potential to occur within the Study Area based on the literature review (CDFW 2018a). These included Great Valley Valley Oak Riparian Forest, Ione Chaparral, Northern Hardpan Vernal Pool, Northern Volcanic Mudflow Vernal Pool, and Valley Needlegrass Grassland. Valley oaks are not present within the Study Area; therefore, Great Valley Oak Riparian Forest does not occur onsite. Vernal pool communities are present onsite, and are discussed separately in Section 4.3.2. No chaparral vegetation is present within the Study Area and there are no Ione formation soils present; therefore, Ione chaparral is not present. The “Valley Needlegrass Grassland” vegetation alliance name used by the CNDDB is no longer in use, and instead “Needlegrass-Melic Grass Grassland” as well as other associations containing needlegrass (Stipa spp.) are now used by the California Vegetation Manual (CNPS 2018b) and the CDFW-maintained list of sensitive natural communities. No needlegrass species were found during special-status plant surveys (Attachment D). Therefore, vernal pool communities are the only sensitive natural community known to occur within the Study Area.

4.8 Trees
An arborist survey was conducted for the Study Area in October 2018 and June 2019 (Attachment H). A total of 247 trees greater than 6 inches dsh were mapped within the Study Area, and all tree species are nonnative to the region. There are 149 trees that have a dsh equal to or greater than 12 inches and therefore meet the definition of a Protected Tree as defined in the City of Rancho Cordova’s Tree ITEM 11.1. ATTACHMENT 4

Biological Resources Assessment for The Preserve Development ECORP Consulting, Inc.

The Preserve 41 July 27, 20212018-205
Preservation Ordinance. The 149 Protected Trees include redwood (Sequoia sempervirens), eucalyptus (Eucalyptus spp.), callery pear (Pyrus calleryana), American sweetgum (Liquidambar styraciflua), Brazilian pepper-tree (Schinus terabinthifolia), deodar cedar (Cedrus deodara), white mulberry (Morus alba).

5.0 IMPACT ANALYSIS

5.1 Special-Status Species
The Project would require mass grading of the site. As such, the Project would have the potential to have a substantial adverse effect, either directly or through habitat modifications, on special-status species identified by CDFW, and/or USFWS. In addition, the Project is located within the USFWS Mather Core Area, an area prioritized for the conservation and recovery of federally threatened and endangered vernal pool species.

Of the 27 species identified as Present or Potential to Occur within the Study Area, 20 species are SSHCP Covered Species and are considered adequately conserved by the SSHCP. Project impacts on specialstatus species habitat are anticipated to be mitigated through the SSHCP In-Lieu Fee Program, and the Project proponents will comply with SSHCP AMMs as described in Section 6.0. The SSHCP also considers priorities for conservation and recovery of vernal pool species within the Mather Core Area.

The remaining seven species having Potential to Occur or Low Potential to Occur onsite that are not SSHCP Covered Species include one plant, one vernal pool invertebrate, one bat, and four birds. Though not Covered Species, the potential impacts to these species are also anticipated to be mitigated by SSHCP AMMs and by the restoration, enhancement and preservation of habitats accomplished by the SSHCP inlieu fee program. Section 6.0 provides recommended mitigation measures. Measures BIO-5 through 14 are recommended to be implemented in order to minimize effects on special-status species.

5.2 Sensitive Natural Communities
The Study Area primarily consists of Valley Grassland that supports mostly nonnative grass and forb species, and aquatic features including vernal pool habitat. Project impacts to vernal pool communities are discussed in Section 5.3 and addressed by Mitigation Measures BIO-1 and BIO-5 (Section 6.0).

5.3 Federally Protected Wetlands and Waters of the U.S.

The Project is anticipated to impact (fill) up to roughly 4.727 acres of Waters of the U.S. The Project applicants are anticipated to apply for CWA Section 404 and 401 authorization under the SSHCP ARP, and to mitigate for Project impacts using the SSHCP In-Lieu Fee Program. Mitigation Measures BIO-1, BIO-2, and BIO-5 are recommended to address impacts to wetlands and other Waters of the U.S.

5.4 Wildlife Corridors and Nursery Sites
The Study Area does not fall within an Essential Habitat Connectivity area mapped by the CDFW (CDFW 2018a). In addition, the Project will have minimal impacts to Morrison Creek. Recommended Mitigation Measure BIO-3 requires a 100-foot setback from Morrison Creek for certain development activities that ITEM 11.1. ATTACHMENT 4

Biological Resources Assessment for The Preserve Development ECORP Consulting, Inc.

The Preserve 42 July 27, 20212018-205
are considered detrimental to stream/creek corridors. Morrison Creek is the only potential wildlife corridor near the site; therefore, no impacts on wildlife corridors are anticipated as a result of Project development.

5.5 Local Policies and Ordinances
The Project would remove ±142 of the 149 Protected Trees (as defined by the City of Rancho Cordova Tree Preservation Ordinance) from the Project area. The nine trees within the Morrison Creek Offsite will be avoided.

The Protected Trees onsite may provide nesting habitat for birds and roosting habitat for bats; however, none of the trees to be removed are native to the Central Valley, and several of the species are considered potentially invasive according to the California Invasive Plant Council Inventory (i.e., eucalyptus, callery pear, Brazilian pepper-tree).

Per the City of Rancho Cordova Tree Preservation Ordinance Section 19.12.070, the Public Works Director will consider the potential for the trees being removed to be a public nuisance and the overall impact on the environment (among other considerations). Removal of these trees is not anticipated to result in negative impacts on the environment aside from potential effects on nesting habitat, and the invasive tree species may become a public nuisance. For example, invasion by eucalyptus species can lead to increased fire hazard, increased soil erosion, and poor wildlife habitat quality (Rejmanek and Richardson 2011).

Eucalyptus trees were planted along roadsides and around buildings within the Study Area, but appear to have invaded the adjacent riparian area along Morrison Creek. Replacement of trees with similar species is not recommended; however, incorporating locally native trees into the Project’s landscaping design will maintain habitat for bird species and reduce invasion of nonnative species into adjacent habitats.

Recommended Mitigation Measure BIO-14 addresses impacts to Protected Trees.

5.6 Habitat Conservation Plans
The Project is anticipated to apply for permits through the SSHCP and the ARP and the Project will comply with the SSHCP’s requirements and AMMs as discussed in the recommended Mitigation Measures in Section 6.0 (full text of AMMs is provided as Attachment I). The Project impacts are anticipated to be mitigated through the SSHCP In-Lieu Fee Program as discussed in BIO-5.

6.0 RECOMMENDATIONS
The following Mitigation Measures are recommended prior to Project implementation in order to mitigate impacts on biological resources. Many of the Mitigation Measures reference SSHCP AMMs, the full text of which can be found in Attachment I.

BIO-1. Obtain Clean Water Act Section 404 Permit and Section 401 Permit and Implement All Permit Conditions:

Before the approval of grading and improvement plans and before any groundbreaking activity associated with the project, the Project applicants shall ensure that authorization pursuant to CWA Section 404 from the USACE and CWA Section 401 from the Central Valley RWQCB is obtained.

sensitive natural communities were detected. For the Raymer Way Offsite, Project applicants shall comply with SSHCP AMM PLANT 1 (Rare Plant Surveys) conduct special-status plant surveys prior to construction.

Habitat for Orcuttia species was determined to be absent from the Raymer Way Offsite; therefore, ORCUTT-1 does not apply. Though stinkbells is not considered an SSHCP Covered Species, special-status plant surveys conducted per PLANT-1 shall identify whether this species is present onsite.

If any SSHCP-covered plants are determined to be present, PLANT-2 (Rare Plant Protection) will be implemented. If stinkbells is determined to be present, a mitigation plan shall be prepared for review and approval by the City of Rancho Cordova and mitigation may include harvesting and transplanting of impacted bulbs into a preserved area with suitable habitat. Avoided areas containing stinkbells shall be fenced with orange construction fencing.

BIO-7. Western Spadefoot:

The Project applicants shall comply with SSHCP AMMs WS-1 through WS-6.

BIO-8. Western Pond Turtle:

There is no SSHCP Modeled Habitat for western pond turtle within the Project; however, the ponded areas along Morrison Creek may provide potential habitat for western pond turtle. Therefore, pre-construction surveys will be conducted per SSHCP AMM WPT-1. If western pond turtles are detected, WPT-2 through WPT-9 will be implemented.

BIO-9. Tricolored Blackbird:

The Project applicants shall comply with SSHCP AMMs TCB-2 through TCB-5. If tricolored blackbirds are found within the survey area during the pre-construction survey conducted per TCB-2, then TCB-3 through TCB-5 will be implemented as required based on the results of surveys conducted per TCB-2.

BIO-10. Swainson’s Hawk:

The Project applicants shall comply with SSHCP AMMs SWHA-2 through SWHA-4. If Swainson’s hawk nesting is found within the survey area during the pre-construction survey conducted per SWHA-2, then SWHA-3 and SWHA-4 will be implemented as required based on the results of surveys conducted per SWHA-2.

BIO-11. Western Burrowing Owl:

The Project applicants shall comply with SSHCP AMMs WBO-2 through WBO-7. If western burrowing owl is found within the survey area, WBO-3 through 7 shall be implemented as required based on the results of surveys conducted per WBO-2.

BIO-12. Other Raptors:

The Project applicants shall comply with SSHCP AMMs RAPTOR-2 through RAPTOR-4. Raptor surveys conducted per RAPTOR-2 shall include surveying for golden eagle although it is not a SSHCP Covered Species.

Biological Resources Assessment for The Preserve Development ECORP Consulting, Inc.

The Preserve 45 July 27, 20212018-205
and RAPTOR-4 shall be implemented as required based on the results of surveys conducted per RAPTOR-2.

BIO-13. Other Nesting Birds:

A qualified biologist shall conduct a preconstruction nesting bird survey of all areas associated with construction activities, and a 100-foot buffer around these areas, within 14 days prior to commencement of construction if construction occurs during the nesting season (February 1 through August 31). If active nests are found for any SSHCP Covered Species, the applicable SSHCP AMM(s) will be implemented (i.e.

TCB-3 through -5, SWHA-3 through -4, WBO-3 through -6, and RAPTOR-3 through -4). If active nests are found for any other species, a no-disturbance buffer around the nest shall be established. The buffer distance shall be established by a qualified biologist in consultation with the CDFW. The buffer shall be maintained until the fledglings are capable of flight and become independent of the nest, to be determined by a qualified biologist. Once the young are independent of the nest, no further measures are necessary.

BIO-14. Bat Species:

The Project applicants shall comply with SSHCP AMMs BAT-2 through BAT-5. Winter hibernaculum surveys conducted per BAT-2 shall also include surveying for pallid bat although it is not an SSHCP Covered Species.

BIO-15. American Badger:

A qualified biologist shall conduct a preconstruction survey for American badger within 14 days prior to commencement of construction and results of the survey will be provided to the City’s Planning Department. If badgers or dens with signs of recent badger use are detected (i.e., fresh scat, claw marks), CDFW will be consulted and a non-disturbance buffer will be established around any active dens. The den(s) will be monitored daily by the qualified biologist during construction. No work will occur within the non-disturbance buffer until the qualified biologist determines that the badger(s) have left the work area, or as determined in consultation with CDFW.

BIO-16. Protected Tree Removal and Incorporating Native Trees into Landscaping Design:

A tree removal permit shall be procured from the City for removal of any Protected Trees. In addition, tree species that are native to the Central Valley and Sierra Nevada foothills such as interior live oak (Quercus wislizeni), valley oak (Quercus lobata), blue oak (Quercus douglasii), Fremont cottonwood (Populus fremontii), black walnut (Juglans hindsii), and western redbud (Cercis occidentalis) shall be incorporated into the planned landscaping design in public spaces such as open space, parks and parkways. Enough plantings of these native trees shall be incorporated into the landscaping such that the number of surviving native trees after five years is equal to or greater than the number of non-native trees removed.

Landscaping plans detailing the tree species to be planted will be provided to the City for approval prior to tree planting.

RE: Bird and Bat Potential Habitat Assessment Surveys – The Preserve Development Project, Rancho Cordova, California
Dear Mr. Carpenter:

At the request of Winn Communities, Inc., ECORP Consulting, Inc. has conducted surveys for bird and bat habitat within the ±98.92-acre The Preserve Development Project (Project) and the ±9.33-acre potential Offsite areas. The Project is located northwest of Raymer Way and Grant Line Road in the City of Rancho Cordova, Sacramento County, California (Figure 1. Project Location and Vicinity). This letter supercedes the letter sent on December 10, 2018.

As required by the South Sacramento Habitat Conservation Plan (SSHCP) Avoidance and Minimization Measures (AMMs), surveys for potential habitat were conducted for tricolored blackbird (TRBL, Agelaius tricolor), Swainson’s hawk (SWHA; Buteo swainsoni) and other raptors, burrowing owls (BUOW; Athene cunicularia), and western red bats (LABL; Lasiurus blossevillii). In addition, potential habitat for pallid bat (ANPA; Antrozous pallidus) was also assessed. Each survey also included buffers around the Project and Offsite areas as required by the AMMs for each species, as described below in the Survey Methods section.

REGULATORY CONTEXT
South Sacramento Habitat Conservation Plan
The SSHCP is a regional effort that will provide development and infrastructure projects with streamlined federal and state permitting processes while creating a preserve system to protect habitat, open space, and agricultural lands (County of Sacramento et al. 2018). The SSHCP allows project proponents within the Plan Area to simplify and expedite the state and federal ESA permitting process. In addition to streamlining the ESA permitting processes, a parallel Aquatic Resources Program (ARP) has been developed to address permitting pursuant to the Clean Water Act Section 404 and 401 permitting process. In addition, a Master Streambed Alternation Agreement will be requested by the SSHCP Implementing Entities to address Section 1602 of the California Fish and Game Code. The SSHCP will allow Sacramento County, the City of Rancho Cordova, City of Galt, and the Southeast Connector Joint Powers Authority to receive Incidental Take Permits (ITP) for Covered Species from USFWS and CDFW for activities and projects they conduct. In addition, the three local Land Use Authority Permittees (the County, Galt, and Rancho Cordova) can extend incidental take coverage provided by the SSHCP ITPs to activities and ITEM 11.1. ATTACHMENT 4

projects implemented by Third-Party Project Proponents that are under the jurisdiction of that Land Use Authority Permittee. See www.southsachcp.com for more information.

SSHCP Covered Species
TRBL, SWHA, BUOW and LABL are SSHCP Covered Species. Habitat surveys for these species were determined to be required for the Project by the following SSHCP AMMs: TCB-1, SWHA-1, RAPTOR-1, WBO-1, and BAT-1.

Pallid Bat
ANPA is not an SSHCP covered species although it is considered a species of special concern by CDFW. A California Natural Diversity Database search revealed a nearby occurrence of ANPA. Therefore, although not an SSHCP-covered species, ANPA was included in the bat habitat assessment for informational purposes.

SURVEY METHODS
Bird Survey
ECORP biologists Keith Kwan and Angela Haas conducted surveys for potential SSHCP-covered bird species habitat within the Project on November 27, 2018. ECORP biologist Matthew Spaulding conducted surveys for potential SSHCP-covered bird species habitat within the potential Offsite areas on June 13, 2019. Inaccessible Offsite areas and surrounding buffers were visually assessed from within the Project or from publicly accessible roads.

Before starting the surveys, the biologists scanned all visible areas of the Project area with binoculars (10X42 magnification). The entire Project Area was visually surveyed on foot, while the surrounding buffers were visually assessed from within the Project or from publicly accessible roads due to private property. During the surveys, all potential nesting habitat were identified and all wildlife species present recorded. The methods below were enacted during surveys as per the SSHCP AMMs.

TCB-1
The biologists walked transects and visually scanned the entire Project area and the accessible portions of the Offsite areas, and visually scanned a 500-foot buffer. All potential TRBL nesting and foraging habitat was recorded and mapped.

SWHA-1 & RAPTOR-1
The biologists walked transects and visually scanned the entire Project and the accessible portions of the Offsite areas. In the surrounding 0.25-mile buffer, accessible public roads were driven, and private property was visually scanned for the presence of SWHA and other raptor nesting habitat. All potential SWHA and raptor nesting trees were recorded and mapped.

ITEM 11.1. ATTACHMENT 4

WBO-1
The biologists walked transects and visually surveyed the Project area and the accessible portions of the Offsite areas for the presence of burrows and/or evidence of BUOW. Transects were spaced 50 feet apart due to good visibility and a lack of dense vegetation. A 250-foot buffer was also visually scanned but not walked due to inaccessible private property. All potential or occupied burrows were recorded and mapped.

Bat Survey
ECORP biologist Matthew Spaulding conducted a survey for potential LABL and ANPA hibernacula on December 4, 2018 and on June 13, 2019. All potential winter hibernaculum habitat was visually scanned with binoculars (10X42 magnification) and assessed for suitability for these species. External physical features of the trees and structures located within the Project area and the Offsite area, including a 300- foot buffer, were examined for evidence of bat use (e.g., presence of guano, evidence of day roost use, culled insect parts, urine staining, odors associated with bats). Mr. Spaulding also listened for chatter indicative of roosting bats at each tree. Inaccessible Offsite areas and surrounding buffers were visually assessed from within the Project or from publicly accessible roads.

The following methods were enacted during the survey as per the SSHCP AMM BAT-1:

BAT-1
Mr. Spaulding walked and visually scanned the Project area and the accessible portions of the Offsite areas, and visually scanned a 300-foot buffer for the presence of LABL winter hibernaculum habitat. All potential LABL winter hibernaculum trees were recorded and mapped.

In addition, the same methods were used for ANPA, though not an SSHCP Covered Species.

RESULTS
Project Setting
The Project is situated at an elevation of approximately 220-240 feet above mean sea level. The Project site included a mix of rural residential and undeveloped rangeland. Two rural residences and associated outbuildings are present within the Project Area. Some horticultural tree stands occur around the residences, as well as eucalyptus (Eucalyptus sp.), cottonwood (Populus sp.) and oak (Quercus sp.). The remaining area is primarily annual grassland used for cattle grazing. A full list of the wildlife species observed on November 27, 2018 and June 13, 2019 are included as Attachments A and B, respectively.

Bird Survey
Potential nesting habitat for TRBL, SWHA and other raptors, and BUOW occurred within the Project and buffer areas, but not within the Offsites. One BUOW was observed within the Project.

Potential nesting habitat for TRBL was found within the Project and within the associated buffer (Figure 2.

Potential Tricolored Blackbird Nesting Habitat). The potential nesting habitat features mapped consisted of ITEM 11.1. ATTACHMENT 4

patches of bull thistle (Cirsium vulgare). Evidence of TRBL nesting during the previous year’s (2018) nesting season was present within these patches, and TRBL was observed onsite during the November 27, 2018 survey; however, no evidence of active nesting was observed during the June 13, 2019 survey.

Potential foraging habitat for TRBL included the grassland and wetland habitats within the Project and Offsites.

Potential nesting habitat for SWHA and other raptors occurred within the Project and within the associated buffer (Figure 3. Potential Swainson’s Hawk and Raptor Nesting Habitat). Potential SWHA nesting habitat included large trees, while potential nesting habitat for other raptors included large and medium-sized trees.

Potential nesting habitat for BUOW occurred within the Project. Numerous unoccupied burrows were mapped along the eastern boundary and the southeastern portion of the Project site (Figure 4. Potential Western Burrowing Owl Burrow Habitat). Of these, one burrow had an individual BUOW present at the time of the survey (noted as “Burrow, Occupied” on Figure 4) and evidence of BUOW presence (e.g. white wash, pellets) was observed at three other burrow locations (noted as “Burrow, with Evidence”). No potential or occupied burrows could be seen within the 250-foot buffer. However, due to access limitations, the surrounding buffer could not be adequately surveyed to rule out the potential presence of suitable burrows or BUOW presence.

Bat Survey
Potential hibernaculum habitat for LABL occurred within the 300-foot buffer but not within the Project or Offsite areas. Potential hibernaculum occurred in the form of a large snag, two cottonwood trees, large eucalyptus trees all with suitable cavities and/or exfoliating bark (Figure 5. Potential Western Red Bat and Pallid Bat Hibernacula). There was no visible sign indicating bats were currently using the habitat.

Potential hibernaculum habitat for ANPA occurred within the Project site, but not within the buffer or Offsite areas. Potential hibernacula for ANPA were present in the form of structures with gaps or vents that could allow access to buildings (Figure 5. Potential Western Red Bat and Pallid Bat Hibernacula). There was no visible sign indicating bats were currently using the habitat.

RECOMMENDATIONS
As per requirements of the SSHCP, subsequent AMMs may need to be implemented based on the results of these surveys. Please refer to Section 5.4.2 of the SSHCP for more information on required AMMs.

If you have any questions, please call me or Taraneh Emam at (916) 782-9100.

Sincerely,
Keith Kwan
Senior Biologist

1.0 INTRODUCTION
ECORP Consulting, Inc. has conducted a special-status plant survey for the proposed The Preserve Development (Project) located in Rancho Cordova, California. The purpose of this survey was to identify and map the locations of special-status plant species observed within the Project.

1.1 Project Location
The Study Area includes the 98.92-acre Project area, as well as five potential Offsite areas totaling 9.33 acres.

In this document the Offsite areas are referred to as the Rio del Oro Offsite (located to the west of the Project), the Raymer Way Offsite (located to the east of the Project), the Morrison Creek Offsite (located to the north of the Project around an existing crossing of Morrison Creek), and the North Douglas Offsites (two road stubs located to the south of the Project within the existing North Douglas development).

The Study Area is located to the west of Raymer Way and Grant Line Road in Rancho Cordova, California.

The Study Area corresponds to an unsectioned portion of the Rio de los Americanos Land Grant within the “Buffalo Creek, California” 7.5-minute quadrangle (U.S. Geological Survey [USGS] 1980) (Figure 1. Study Area Location and Vicinity). The approximate center of the site is located at 38.574614° North and -121.196708° West within the Lower Sacramento Watershed (Hydrologic Unit Code #18020163, USGS 2016).

For the purposes of this report, “special-status plants” are defined as plants which meet one or more of the following:
 Plants listed, proposed for listing, or candidates for future listing as threatened or endangered under the federal Endangered Species Act (ESA);
 Plants listed, proposed for listing, or candidates for future listing as threatened or endangered under the California ESA;
 Plants that meet the definitions of endangered or rare under Section 15380 of the State California Environmental Quality Act (CEQA) Guidelines;
 Plants listed as rare under the California Native Plant Protection Act (California Department of Fish and Game [CDFG] Code of California, Section 1900 et seq.);  Plants considered by the California Native Plant Society (CNPS) to be "rare, threatened, or endangered in California" [California Rare Plant Rank (CRPR) 1B and 2] (see Section 1.3);  Plants listed by CNPS as species about which more information is needed to determine their status (CRPR 3), and plants of limited distribution (CRPR 4); and  Plants that are South Sacramento Habitat Conservation Plan (SSHCP) Covered Species (see Section 1.4).

1.3 California Rare Plant Ranks
CNPS maintains the Inventory of Rare and Endangered Plants of California (CNPS 2019), which provides a list of plant species native to California that are threatened with extinction, have limited distributions, and/or low populations. Plant species meeting one of these criteria are assigned to one of six ranks (i.e., CRPR).

The rank system was developed in collaboration with government, academia, non-governmental organizations, and private sector botanists, and is jointly managed by the California Department of Fish and Wildlife (CDFW) and the CNPS. The ranks are currently recognized in the California Natural Diversity Database (CNDDB). The following are definitions of the CNPS CRPRs:
 CRPR 1A – presumed extirpated in California and either rare or extinct elsewhere;  CRPR 1B – rare, threatened, or endangered in California and elsewhere;  CRPR 2A – presumed extirpated in California, but more common elsewhere;  CRPR 2B – rare, threatened, or endangered in California but more common elsewhere;  CRPR 3 – a review list of plants about which more information is needed; and  CRPR 4 – a watch list of plants of limited distribution.

Additionally, the CNPS has defined Threat Ranks that are added to the CRPR as an extension. Threat Ranks designate the level of threat on a scale of 0.1 through 0.3, with 0.1 being the most threatened and 0.3 being the least threatened. Threat Ranks are generally assigned for all plants ranked 1B, 2B, or 4, and for the majority of plants ranked 3. Plant species ranked 1A and 2A (presumed extirpated in California), and some species ranked 3, which lack threat information, do not typically have a Threat Rank extension. The following are definitions of the CNPS Threat Ranks:
 Threat Rank 0.1 – Seriously threatened in California (over 80% of occurrences threatened / high degree and immediacy of threat);
 Threat Rank 0.2 – Moderately threatened in California (20-80% occurrences threatened / moderate degree and immediacy of threat); and
 Threat Rank 0.3 – Not very threatened in California (<20% of occurrences threatened / low degree and immediacy of threat or no current threats known).

Factors, such as habitat vulnerability and specificity, distribution, and condition of occurrences, are considered in assigning the Threat Rank, and differences in Threat Ranks do not constitute additional or different protection (CNPS 2019). Depending on the policy of the lead agency, substantial impacts to plants listed as CRPR 1A, 1B, 2, and 3 (regardless of threat rank) are typically considered significant under CEQA Guidelines Section 15380. For CRPR 4 species (regardless of threat rank), significance under CEQA is typically evaluated if the lead agency has determined those plants to be of local significance or regional importance.

Such plants may be identified in local Habitat Conservation Plans (HCPs) or City or County General Plans.

1.4 South Sacramento Habitat Conservation Plan
The SSHCP is a regional effort that will provide development and infrastructure projects with streamlined federal and state permitting processes while creating a preserve system to protect habitat, open space, and agricultural lands (County of Sacramento et al. 2018). The SSHCP allows project proponents within the Plan Area to simplify and expedite the state and federal ESA permitting process. The SSHCP will allow Sacramento County, the City of Rancho Cordova, City of Galt, and the Southeast Connector Joint Powers Authority to receive Incidental Take Permits (ITP) for 28 Covered Species from U.S. Fish and Wildlife Service and CDFW for activities and projects they conduct. In addition, the three local Land Use Authority Permittees (the County, Galt, and Rancho Cordova) can extend incidental take coverage provided by the SSHCP ITPs to activities and projects implemented by Third-Party Project Proponents that are under the jurisdiction of that Land Use Authority Permittee. The SSHCP provides Modeled Species Habitat data for each Covered Species to determine whether Covered Species have potential to occur within a project site. The SSHCP also sets forth Avoidance and Minimization Measures with which permittees must comply. See www.southsachcp.com for more information.

Table 1 provides a list of all plant species that are considered SSHCP Covered Species, adapted from Table 1-2 of the SSHCP (County of Sacramento et al. 2018).

2.0 METHODS

2.1 Literature Review
Prior to conducting field surveys, background information was collected on the potential presence of special-status plants within or near the survey area from a variety of sources. This included a review of resource agency species lists, literature review, on-line database query, voucher specimen review, and reference population review. The following resources were used as part of the literature review:
 CDFW California Natural Diversity Database (CNDDB) data for the “Buffalo Creek, California” 7.5- minute quadrangle as well as the eight surrounding USGS quadrangles (CDFW 2019);  USFWS Resource Report List Federal Endangered and Threatened Species that may be affected by the Project (USFWS 2019); and
 CNPS’s electronic Inventory of Rare and Endangered Plants of California for the “Buffalo Creek, California” 7.5-minute quadrangle as well as the eight surrounding USGS quadrangles (CNPS 2019).  SSHCP Modeled Species Habitat for the Study Area.

2.2 Special-Status Plants Considered for the Project
Based on species occurrence information from the CNDDB, the literature review, and general site knowledge, a list of special-status plant species that are known to occur or have the potential to occur within the survey area was generated (Attachment A). Only special-status plants as defined in Section 1.2 were included in this analysis. Each of these species’ potential to occur within the survey area was assessed based on the following criteria:
 Present - Species was previously observed during field surveys or is known to occur within the Study Area based on documented occurrences within the CNDDB, SSHCP, or other literature.  Potential to Occur - Habitat (including soils and elevation requirements) for the species occurs within the Study Area based on site assessment, literature research, or SSHCP Modeled Species Habitat data.
 Low Potential to Occur - Marginal or limited amounts of habitat occur, and/or the species is not known to occur within the vicinity of the Study Area based on CNDDB records and other available documentation. This designation is only used for species that are not SSHCP Covered Species.  Absent - No suitable habitat (including soils and elevation requirements) and/or the species is not known to occur within the vicinity of the Study Area based on CNDDB records and other documentation and SSHCP Modeled Species Habitat data does not indicate that habitat for the species occurs within the site.

2.3 Target Species
Based on the analysis of potentially occurring special-status plant species for the survey area, the plants listed in Table 2 were considered to be the Target List for this survey effort. Species determined to be Absent are not included in the target list.

2.4 Reference Site Visits
Reference populations, where available, for the seven target species were visited to assess bloom phenology and to observe species morphology. When reference populations were not available, photographs from Calflora (Calflora 2019) and The Jepson Manual: Vascular Plants of California, Second Edition (Baldwin et al. 2012) were used as a reference. Attachment B identifies the reference source for each of the target species including the location of the population, dates of visits, and phenological stage of the species at the time of the field visits.

2.5 Field Surveys
Determinate-level field surveys were conducted in accordance with SSHCP Avoidance and Minimization Measures PLANT-1 and ORCUTT-1, as well as guidelines promulgated by USFWS (USFWS 2000), CDFW (CDFW 2018), and CNPS (CNPS 2001). The special-status plant surveys were conducted on April 29, 2019 and June 13, 2019 by ECORP biologist Casey Peters and Benjamin Waitman. A list of field personnel qualifications is included as Attachment C. The surveys coincided with the optimum identifiable periods for each of the target species.

Within the Project, Morrison Creek Offsite, and North Douglas Offsite, the biologists walked meandering transects to ensure complete coverage of all suitable habitat for all target species. The Rio del Oro Offsite and Raymer Way Offsite were assessed to the degree possible from accessible areas (i.e. within the Project and along roads), but transects across these offsites were not surveyed.

A complete plant list of all plants observed during the surveys was generated (Attachment D). All species were identified to the lowest possible taxonomic level required to assess rarity. Plant species identification, nomenclature, and taxonomy followed The Jepson Manual (Baldwin et al. 2012). Vegetation community classification was based on the classification systems presented in A Manual of California Vegetation, Second Edition (Sawyer et al. 2009).

3.0 EXISTING SITE CONDITIONS
The Study Area is situated at an elevation range between approximately 200 and 250 feet above mean sea level (MSL) in Rancho Cordova, California. The Study Area is located in the Great Valley region, Sacramento Valley subregion of the California Floristic Province (Baldwin et al. 2012). This region is characterized by agricultural areas, grasslands, wetlands, and valley oaks (Baldwin et al. 2012). The average annual precipitation for the region is 36.9 inches (with the wettest period during November-March), and average daily temperatures range from 47.7˚F in winter to 73.8˚F in summer (National Oceanic and Atmospheric Administration [NOAA] 2018).

The Study Area is characterized by flat to gently rolling terrain and consists primarily of grazed annual grasslands with two residences and other outbuildings. A private road, sometimes identified as Douglas Road, leads from south of the Study Area into the two residences. The Study Area is located within the USFWS Mather Core Area (USFWS 2005a). Core Areas are areas prioritized for the conservation and recovery of threatened and endangered vernal pool species.

3.1 Land Cover Types
SSHCP land cover data within the Study Area were reviewed and field-revised as needed. Revised land cover types are shown in Figure 2. More information on land cover types is provided in the Biological Resources Assessment for the Project (ECORP 2019).

3.1.1 Terrestrial Land Cover Types
The Study Area primarily contains the Valley Grassland SSHCP land cover type. The Study Area also contains Low Density Development and a small amount of Disturbed and Major Roads land cover.

Valley Grassland
The Valley Grassland land cover type is predominantly characterized by non-native (naturalized) annual grasses. Within the Study Area, the common plant species found in Valley Grassland are a mixture of nonnative annual grasses, including medusahead grass (Elymus caput-medusae), soft brome (Bromus hordeaceus), wild oats (Avena fatua), and brome fescue (Festuca bromoides). Narrow tarplant (Holocarpha virgata), a native perennial forb, is also common in this land cover type within the Study Area.

Low Density Development
The Low Density Development land cover type consists of existing homesteads including buildings/structures and horticultural trees.

Disturbed/Major Roads
The Disturbed and Major Roads land cover types consists of sections of paved road within the Study Area.

3.1.2 Aquatic Land Cover Types
An aquatic resources delineation was conducted for the Study Area, in accordance with the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (USACE 2008).

A discussion of the aquatic resources found onsite is presented below, and Figure 2 includes aquatic land cover types (field delineation was used to revise the SSHCP baseline land cover data for aquatic resources).

Vernal Pool
Vernal pools are seasonal ephemeral wetlands that fill and dry each year, forming in shallow depressions within Valley Grassland that are underlaid by an impermeable layer (e.g. a hardpan). Water collects in the depressions during the winter rainy season and recedes during the spring. Soils typically remain moist until late spring before becoming desiccated, and then remain dry throughout the summer. Vernal pools provide habitat for several special-status species, including invertebrates, plants, and amphibians.

Vernal pools occur throughout the Study Area. These features are variously dominated by Great Valley button-celery (Eryngium castrense), stalked popcorn flower (Plagiobothrys stipitatus), woolly marbles (Psilocarphus brevissimus), Mediterranean barley (Hordeum marinum), waxy mannagrass (Glyceria declinata), hairy hawkbit (Leontodon saxatilis), and toad rush (Juncus bufonius).

ITEM 11.1. ATTACHMENT 4

Swale
Swales are shallow ephemeral drainages found in flat to gently rolling Valley Grassland in association with vernal pool complexes, on soils with an impermeable layer. Swales convey runoff as shallow, gently sloping ephemeral wetlands during and shortly after winter rainstorms, but usually maintain soil saturation for longer periods during the growing season. They typically have hydric soils and support hydrophytic vegetation but lack an ordinary high-water mark (OHWM). Swales serve as habitat for many vernal pool species and provide hydrological connections between vernal pools that allows movement/dispersal of amphibian species, plant seeds, and vernal pool invertebrates (both adults and cysts).

Swales occur throughout the Study Area, and are dominated by Italian ryegrass (Festuca perennis), Fitch’s spikeweed (Centromadia fitchii), and Mediterranean barley.

Stream/Creek
The Stream/Creek land cover type includes intermittent and perennial linear water features such as rivers, streams, creeks, drainages, and roadside and irrigation ditches. These features typically exhibit a bed and bank and an OHWM. Morrison Creek is located to the north of the Study Area, and several small headwater tributaries to the creek flow through the Study Area into Morrison Creek. Stream/creek features occur throughout the Study Area, flowing north to Morrison Creek, and vary from steep, unvegetated features, to gently sloping features that are sparsely vegetated with creeping spikerush (Eleocharis macrostachya).

3.2 Soils
According to the Web Soil Survey (NRCS 2018), two soil units, or types, have been mapped within the Study Area (Figure 2. Natural Resources Conservation Service Soil Types):
 (159) Hicksville gravelly loam, 0 to 2 percent slopes, occasionally flooded  (193) Red Bluff-Redding complex, 0 to 5 percent slopes Hicksville and Red Bluff soils are formed in alluvium derived from mixed rock sources. Redding soils are formed in gravelly and cobbly alluvium derived from mixed rock sources (NRCS 2018). No soil units derived from serpentinite or other ultramafic parent materials have been reported to occur within the Study Area or its immediate vicinity (NRCS 2018). Furthermore, no apparent inclusions of ultramafic rocks or soils were observed during the field survey.

4.0 SPECIES DESCRIPTIONS
As listed in Section 2.3, seven special-status plants were considered to be target species for this survey. A description of each target species is provided in the following sections.

4.1 Stinkbells
Stinkbells (Fritillaria agrestis) is not listed pursuant to either the federal or California ESAs, but is designated as a CRPR 4.2 species. This species is a perennial bulbiferous herb that occurs in clay, sometimes serpentine areas in chaparral, cismontane woodland, pinyon and juniper woodland, and ITEM 11.1. ATTACHMENT 4

Slender Orcutt grass (Orcuttia tenuis) is listed as threatened and endangered pursuant to both the federal and California ESAs, respectively, and is designated as a CRPR 1B.1 species. This species is an herbaceous annual that occurs in vernal pools (CNPS 2019) primarily on substrates of volcanic origin (Crampton 1959, Corbin and Schoolcraft 1989; as cited in USFWS 2005a). This species is known to occur in the same type of vernal pool complexes as Sacramento Orcutt grass in Sacramento County; however, these species have not been observed co-existing in the same vernal pool (USFWS 2005a). The median area of pools occupied by populations studied by Stone et al. (1988, as cited in USFWS 2005a) was 1.6 acres and ranged from 0.2 to 111.0 acres (USFWS 2005a). Slender Orcutt grass blooms from May through October and is known to occur at elevations ranging from 115 to 5,774 feet above MSL (CNPS 2019). Slender Orcutt grass is endemic to California; the current range for this species includes Butte, Lake, Lassen, Modoc, Plumas, Sacramento, Shasta, Siskiyou, and Tehama counties (CNPS 2019).

There is one documented CNDDB occurrence of this species located within five miles of the Study Area (CDFW 2019). Slender Orcutt grass is a SSHCP Covered Species, and the grassland and vernal pools within the Study Area provide suitable habitat for this species according to SSHCP Modeled Species Habitat.

Slender Orcutt grass has potential to occur within the Study Area.

5.0 RESULTS
ECORP conducted special-status plant surveys on April 29, 2019 and June 13, 2019 within the Study Area.

The Rio del Oro Offsite and Raymer Way Offsite were assessed to the degree possible from accessible areas, but transects across these offsites were not surveyed. No special-status plant species were observed during the special-status plant surveys. However, the Raymer Way Offsite was not accessible for a complete survey, and the grassland within this offsite may represent potential habitat for stinkbells and Ahart’s dwarf rush.

White-headed navarretia (Navarretia leucocephala) was observed within the Project. White-headed navarretia is a common species with no special status, but is difficult to distinguish from pincushion navarretia (Navarretia myersii), which has a CRPR of 1B.1 and is an SSHCP Covered Species. While pincushion navarretia was not considered a target species for the surveys because no SSHCP Modeled Species Habitat was mapped within the Study Area, ECORP consulted with experts at the University of California, Davis Herbarium, and identification of the species as white-headed navarretia was confirmed based on the following characteristics:
• Stems greater than 2.5cm
• Sparseness of puberulent hairs on the calyx
• Flower tubes shorter than typical for pincushion navarretia ITEM 11.1. ATTACHMENT 4

• Inflorescence is a tightly packed cyme, rather than a true head

6.0 CONCLUSION
No special-status plant species were documented within the Project or publicly accessible portions of the Offsites. However, there is potential for stinkbells and Ahart’s dwarf rush to occur in unsurveyed areas of the Raymer Way Offsite.

While the SSHCP Modeled Species Habitat was used to determine the target species list for this survey, the survey was comprehensive and included identification of each species encountered.

1.0 INTRODUCTION
On behalf of Winn Communities, Inc., ECORP Consulting, Inc. conducted an aquatic resources delineation for the ±113.8-acre Delineation Area encompassing The Preserve Development (Project) located in Rancho Cordova, Sacramento County, California. The Delineation Area is located to the northwest of Raymer Way and Grant Line Road. The Delineation Area corresponds to an unsectioned portion of the Rio de los Americanos Land Grant within the “Buffalo Creek, California” 7.5-minute quadrangle (U.S.

Geological Survey [USGS] 1980) (Figure 1. Project Location and Vicinity). The approximate center of the Delineation Area is located at 38.574873° latitude and -121.196728° longitude within the Lower Sacramento Watershed (Hydrologic Unit Code #18020163, Natural Resources Conservation Service [NRCS], USGS, and U.S. Environmental Protection Agency [USEPA] 2016). Driving directions to the Delineation Area are included as Attachment A.

This report describes aquatic resources identified within the Delineation Area that may be regulated by the U.S. Army Corps of Engineers (USACE) pursuant to Section 404 of the federal Clean Water Act (CWA).

The information presented in this report provides data required by the USACE Sacramento District’s Minimum Standards for Acceptance of Aquatic Resources Delineation Reports (USACE 2016a). A Preliminary Jurisdictional Determination (PJD) was issued in 2012 for a ±72.6-acre portion of the Delineation Area, verifying the location and extent of aquatic resources delineated therein (USACE 2012, Attachment B). The aquatic resource boundaries depicted in this report, including those located in the previously verified portion of the Delineation Area, represent a calculated estimation of the jurisdictional area within the Delineation Area, and are subject to modification following the USACE verification process.

The purpose of this report is to provide adequate information to USACE for the issuance of a PJD covering the entirety of the Delineation Area.

2.0 REGULATORY SETTING

2.1 Waters of the United States
This report describes aquatic resources, including wetlands that may be regulated by USACE under Section 404 of the federal CWA. The following sections define these regulations.

2.1.1 Wetlands
Wetlands are “those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” [51 Federal Register (FR) 41250, Nov. 13, 1986, as amended at 58 FR 45036, Aug. 25, 1993]. Wetlands can be perennial or intermittent.

ITEM 11.1. ATTACHMENT 4

2.1.2 Other Waters
Other waters are nontidal, perennial, and intermittent watercourses and tributaries to such watercourses [51 FR 41250, Nov. 13, 1986, as amended at 58 FR 45036, August 25, 1993]. The limit of USACE jurisdiction for nontidal watercourses (without adjacent wetlands) is defined in 33 Code of Federal Register (CFR) 328.4(c)(1) as the “ordinary high-water mark” (OHWM). The OHWM is defined as the “line on the shore established by the fluctuations of water and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas” approximation of the lateral limit of USACE jurisdiction. The upstream limits of other waters are defined as the point where the OHWM is no longer perceptible.

2.2 Clean Water Act
The USACE regulates discharge of dredged or fill material into Waters of the U.S. under Section 404 of the CWA. “Discharges of fill material” is defined as the addition of fill material into Waters of the U.S., including, but not limited to the following: placement of fill necessary for the construction of any structure, or impoundment requiring rock, sand, dirt, or other material for its construction; sitedevelopment fills for recreational, industrial, commercial, residential, and other uses; causeways or road fills; and fill for intake and outfall pipes, and subaqueous utility lines [33 CFR § 328.2(f)]. In addition, Section 401 of the CWA (33 U.S. Code 1341) requires any applicant for a federal license or permit to conduct any activity that may result in a discharge of a pollutant into Waters of the U.S. to obtain a certification that the discharge will comply with the applicable effluent limitations and water quality standards.

Substantial impacts to wetlands, over 0.5 acre of impact, may require an individual permit. Projects that only minimally affect wetlands, less than 0.5 acre of impact, may meet the conditions of one of the existing Nationwide Permits. A Water Quality Certification or waiver pursuant to Section 401 of the CWA is required for Section 404 permit actions; this certification or waiver is issued by the Regional Water Quality Control Board.

2.3 Jurisdictional Assessment
The Clean Water Rule (CWR) was published in June 2015, but implementation of the rule was stayed until September 2018. It is currently (2018) in effect for 22 states, including California, the District of Columbia, and the U.S. territories. The CWR establishes categories of waters that are jurisdictional, waters that are excluded, and waters that require a case-specific significant nexus evaluation to determine if they are Waters of the U.S. By rule, the CWR defines Waters of the U.S. to include Traditional Navigable Waters (TNW), interstate waters, and territorial seas, impoundments of jurisdictional waters, and tributaries and adjacent (i.e., bordering, contiguous, or neighboring) waters to TNW, interstate waters, or territorial seas (USACE and USEPA 2015).

According to the CWR, neighboring is defined as waters located: within 100 feet of the OHWM of a jurisdictional feature, within the 100-year floodplain of a jurisdictional feature and within 1,500 feet of the ITEM 11.1. ATTACHMENT 4

feature, or within 1,500 feet of the high tide line of TNW, interstate water, or territorial sea. Western vernal pools in California and several other location-specific aquatic feature types are evaluated on a case-bycase basis to determine whether they have a significant nexus to TNW, interstate waters, or territorial seas (USACE and USEPA 2015).

Feature types that are categorically excluded from CWA jurisdiction include waste treatment systems, prior converted cropland, ditches with intermittent or ephemeral flow that are not relocated tributaries or excavated in a tributary, ditches that do not flow, directly or indirectly, into a jurisdictional water, artificially irrigated areas that would revert to dry land in the absence of irrigation, artificial, constructed lakes or ponds created by excavating and/or diking dry land, small ornamental waters, artificial reflecting or swimming pools created by excavating and/or diking dry land, water-filled depressions created in dry land incidental to mining or construction activities, erosional features such as gullies, rills, and other ephemeral features that do not meet the definition of tributary, non-wetland swales, and lawfully constructed grassed waterways, and puddles (USACE and USEPA 2015).

3.0 METHODS
This aquatic resources delineation was conducted in accordance with the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Arid West Region Supplement) (USACE 2008).

The boundaries of aquatic resources were delineated through standard field methods (e.g., paired sample set analyses) and aerial photograph interpretation. Field data were recorded on Wetland Determination Data Forms - Arid West Region (Attachment C). A color aerial photograph (1”=200’ scale, NAIP 2016) used to assist with mapping and ground-truthing. Munsell Soil Color Charts (Kollmorgen Instruments Co. 1990) and the Web Soil Survey (NRCS 2018a) were used to aid in identifying hydric soils in the field. The Jepson Manual, 2nd Edition (Baldwin et al. 2012) was used for plant nomenclature and identification.

Field surveys were conducted on October 12, 2018 by ECORP biologist Clay DeLong. Mr. DeLong walked the entire ±41.2-acre unverified portion of the Delineation Area to determine the location and extent of aquatic resources. Paired locations were sampled to evaluate whether or not the vegetation, hydrology, and soils data supported an aquatic resource determination. At each paired location, one point was located such that it was within the estimated aquatic resource area, and the other point was situated outside the limits of the estimated aquatic resource area. Aquatic resources within the unverified portion of the Delineation Area were recorded in the field using a post-processing capable global positioning system unit with sub-meter accuracy (Trimble GeoXT). The previously verified portion of the Delineation Area was reviewed via aerial photograph interpretation and limited field reconnaissance.

3.1 Routine Determinations for Wetlands
To be determined a wetland, the following three criteria must be met:
 A majority of dominant vegetation species are wetland-associated species; ITEM 11.1. ATTACHMENT 4

 Hydrologic conditions exist that result in periods of flooding, ponding, or saturation during the growing season; and
 Hydric soils are present.

3.1.1 Vegetation
Hydrophytic vegetation is defined as the sum total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanent or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present (Environmental Laboratory 1987). The definition of wetlands includes the phrase "a prevalence of vegetation typically adapted for life in saturated soil conditions." Prevalent vegetation is characterized by the dominant plant species comprising the plant community (Environmental Laboratory 1987). The dominance test is the basic hydrophytic vegetation indicator and was applied at each sampling point location. The "50/20 rule" was used to select the dominant plant species from each stratum of the community. The rule states that for each stratum in the plant community, dominant species are the most abundant plant species (when ranked in descending order of coverage and cumulatively totaled) that immediately exceed 50 percent of the total coverage for the stratum, plus any additional species that individually comprise 20 percent or more of the total cover in the stratum (Headquarters USACE [HQUSACE] 1992, USACE 2008).

Dominant plant species observed at each sampling point were then classified according to their indicator status (probability of occurrence in wetlands, Table 1), North American Digital Flora: National Wetland Plant List (Lichvar et al. 2016). If the majority (more than 50 percent) of the dominant vegetation on a site are classified as obligate (OBL), facultative wetland (FACW), or facultative (FAC), the site was considered to be dominated by hydrophytic vegetation.

Table 1. Classification of Wetland-Associated Plant Species1 Plant Species Classification Abbreviation Probability of Occurring in Wetland Obligate OBL Almost always occur in wetlands
Facultative Wetland FACW Usually occur in wetlands, but may occur in non-wetlands Facultative FAC Occur in wetlands and non-wetlands
Facultative Upland FACU Usually occur in non-wetlands, but may occur in wetlands Upland UPL Almost never occur in wetlands
Plants That Are Not Listed
(assumed upland species)
N/L Does not occur in wetlands in any region.
1Source: Lichvar et al. 2016
In instances where indicators of hydric soil and wetland hydrology were present, but the plant community failed the dominance test, the vegetation was re-evaluated using the Prevalence Index. The Prevalence Index is a weighted-average wetland indicator status of all plant species in the sampling plot, where each indicator status category is given a numeric code (OBL=1, FACW=2, FAC=3, FACU=4, and UPL=5) and ITEM 11.1. ATTACHMENT 4

weighting is by abundance (percent cover). If the plant community failed the Prevalence Index, the presence/absence of plant morphological adaptations to prolonged inundation or saturation in the root zone was evaluated.

3.1.2 Soils
A hydric soil is defined as a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (NRCS 2003).

Indicators that a hydric soil is present include, but are not limited to, histosols, histic epipedon, hydrogen sulfide, depleted below dark surface, sandy redox, loamy gleyed matrix, depleted matrix, redox dark surface, redox depressions, and vernal pools.

At each sampling point a soil pit was excavated to the depth needed to document an indicator, to confirm the absence of indicators, or until refusal at each sampling point. The soil was then examined for hydric soil indicators. Soil colors were determined while the soil was moist using the Munsell Soil Color Charts (Kollmorgen Instruments Co. 1990). Hydric soils are formed predominantly by the accumulation or loss of iron, manganese, sulfur, or carbon compounds in a saturated and anaerobic environment. These processes and the features in the soil that develop can be identified by looking at the color and texture of the soils.

3.1.3 Hydrology
Wetlands, by definition, are seasonally or perennially inundated or saturated at or near (within 12 inches of) the soil surface. Primary indicators of wetland hydrology include, but are not limited to: visual observation of saturated soils, visual observation of inundation, surface soil cracks, inundation visible on aerial imagery, water-stained leaves, oxidized rhizospheres along living roots, aquatic invertebrates, water marks (secondary indicator in riverine environments), drift lines (secondary indicator in riverine environments), and sediment deposits (secondary indicator in riverine environments). The occurrence of one primary indicator is sufficient to conclude that wetland hydrology is present. If no primary indicators are observed, two or more secondary indicators are required to conclude wetland hydrology is present.

Secondary indicators include, but are not limited to: drainage patterns, crayfish burrows, FAC-neutral test, and shallow aquitard.

4.0 RESULTS

4.1 Existing Site Conditions
The Delineation Area is located within flat to rolling terrain situated at an elevational range of approximately 210 - 250 feet above mean sea level in the Sacramento Valley Subregion of the Great Central Valley floristic region of California (Baldwin et al. 2012). The average winter low temperature in the vicinity of the Delineation Area is 41.5˚F and the average summer high temperature is 91.2˚F. Average annual precipitation is approximately 20 inches, which falls as rain (National Oceanic and Atmospheric Administration [NOAA] 2018a).

ITEM 11.1. ATTACHMENT 4

 159 – Hicksville gravelly loam, 0 to 2 percent slopes, occasionally flooded; The Delineation Area is composed of a mixture of developed and undeveloped land. Developed areas include two single-family homes and several gravel roads. Rows of redwood (Sequoia sempervirens) and blue gum (Eucalyptus globulus) are planted at several locations adjacent to the roads and homes.

Surrounding land uses include suburban residential developments, aggregate mines, and undeveloped grasslands.

The majority of the Delineation Area is composed of annual grassland, a vegetation community dominated primarily by a mixture of nonnative annual grasses, including medusahead grass (Elymus caput-medusae), soft brome (Bromus hordeaceus), wild oats (Avena fatua), and brome fescue (Festuca bromoides). Narrow tarplant (Holocarpha virgata), a native perennial forb, was also dominant in grasslands within the Delineation Area. See Section 4.2 for detailed descriptions of the vegetation associated with aquatic resources within the Delineation Area.

This aquatic resources delineation was conducted in late summer, outside the blooming season for most plant species. However, most plants were identifiable to species based upon vegetative or fruit morphology. Hydrologic conditions within the Delineation Area were typical for late summer (i.e., dry), and precipitation totals during the water year preceding the survey were only marginally below normal.

During the 2017-2018 water year prior to the field survey (October 1, 2017 to October 1, 2018), approximately 17 inches of precipitation were recorded at the Sacramento 5 ESE reporting station (NOAA 2018b), located approximately 12 miles from the Study Area. The most recent significant precipitation event prior to the surveys occurred on May 25, 2018, resulting in 0.32 inches of rainfall (NOAA 2018b).

4.1.1 California Aquatic Resource Inventory
The California Aquatic Resource Inventory (CARI, San Francisco Estuary Institute [SFEI] 2017) is a statewide map of surface waters and related habitats combining multiple national and regional datasets, including the National Wetlands Inventory, and the National Hydrography Dataset. CARI includes aquatic resource features mapped using a variety of remote sensing and modeling techniques. As such, these aquatic features may or may not exist as represented. In addition, CARI data varies in detail, accuracy, and age, and is meant to be used as a tool to assist with an aquatic resource delineation but not as the only source of information (SFEI 2017).

According to CARI, there are several aquatic features mapped within the Delineation Area (Figure 2.

California Aquatic Resource Inventory Features). These include stream features mapped as fluvial natural and fluvial unnatural, which roughly correspond to onsite streams and creeks. Figure 2 also shows CARI features mapped as individual vernal pools, depressional seasonal, depressional, and riverine, which roughly correspond to onsite vernal pools, open water features, swales, streams, and creeks.

4.1.2 Soils
According to the Web Soil Survey (NRCS 2018a), three soil units, or types, have been mapped within the Delineation Area (Figure 3. Natural Resources Conservation Service Soil Types):

The feature types described in Table 2 were classified according to definitions within the South Sacramento Habitat Conservation Plan (SSHCP, County of Sacramento et al. 2018). However, previously verified features were given different classifications in the original delineation and PJD. Table 3 provides the classifications used in the PJD and the corresponding SSHCP land cover type used in this report.

4.2.1 Wetlands
Vernal Pool
Vernal pools are seasonal ephemeral wetlands that fill and dry each year, forming in shallow depressions within grasslands that are underlain by an impermeable layer (e.g., a hardpan). Water collects in the depressions during the winter rainy season and recedes during the spring. Soils typically remain moist until late spring before becoming desiccated, and then remain dry throughout the summer. Vernal pools occur throughout the Delineation Area. These features are variously dominated by Great Valley buttoncelery (Eryngium castrense), stalked popcorn flower (Plagiobothrys stipitatus), woolly marbles (Psilocarphus brevissimus), Mediterranean barley (Hordeum marinum), waxy mannagrass (Glyceria declinata), hairy hawkbit (Leontodon saxatilis), and toad rush (Juncus bufonius). Sampling points 5, 7, and 9 were collected within vernal pools.

Soil matrix colors within the vernal pools at sampling points 5, 7 and 9 ranged from 10YR4/1 to 7.5YR 4/2.

Redox concentrations colored 5YR 4/6 were present at each of these sampling points. Soils at sampling points 5, 7, and 9 met the criteria for hydric soil indicators Depleted Matrix (F3) and Redox Depressions (F8). Wetland hydrology indicators observed within the vernal pools included Biotic Crust (B12). While hydric soils were observed at sampling points 6N and 10N, no other wetland parameters were observed at uplands adjacent to vernal pools.

Swale
Swales are generally linear wetland features that convey precipitation runoff and support a predominance of hydrophytic vegetation, but do not exhibit an OHWM. These are typically inundated for short periods during and immediately after rain events, but usually maintain soil saturation for longer periods during the wet season. Swales occur throughout the Delineation Area, and are dominated by Italian ryegrass ITEM 11.1. ATTACHMENT 4

(Festuca perennis), Fitch’s spikeweed (Centromadia fitchii), and Mediterranean barley. Sampling Point 1 was collected within a swale.

The soil matrix color within the swale at sampling point 1 was 10YR 4/2 with five percent redox concentrations colored 5YR 4/6. Soils at sampling point 1 were determined to be hydric based on the presence of hydric soil indicator Depleted Matrix (F3). Wetland hydrology indicators observed within onsite swales include Biotic Crust (B12). No wetland parameters were observed at Sampling Point 2N, located in an upland adjacent to Sampling Point 1.

4.2.2 Other Waters
Stream/Creek
Aquatic resources identified as stream/creek within the Delineation Area include ephemeral drainages and a seasonal creek (Morrison Creek). These are linear features that exhibit a bed and bank and an OHWM.

They convey runoff seasonally for short to moderate duration, and may or may not be influenced by groundwater sources. Stream/creek features occur throughout the Delineation Area, and vary from steep, unvegetated features, to gently sloping features that are sparsely vegetated with creeping spikerush (Eleocharis macrostachya). Sampling points 3 and 13 were collected within stream/creek features.

Sampling Point 3 was collected within a steep, narrow ephemeral drainage along the western boundary of the Delineation Area. The soil matrix color at sampling point 3 was 7.5YR 4/2 with 10 percent redox features colored 5YR 4/6. Soils at sampling point 3 met the criteria for hydric soil indicator Depleted Matrix (F3). Wetland hydrology indicator Water Marks (B1) was observed at Sampling Point 3. No wetland parameters were observed at Sampling Point 4N, located in an upland adjacent to Sampling Point 3.

Sampling Point 13 was collected within Morrison Creek, a broad, gently sloped seasonal creek. The soil matrix color at sampling point 13 was 7.5YR 4/2 with 20 percent redox features colored 5YR 4/6. Soils at sampling point 3 met the criteria for hydric soil indicator Depleted Matrix (F3). Wetland hydrology indicators Water Marks (B1) and Biotic Crust (B12) were observed at Sampling Point 13. Hydric soil indicator Depleted Matrix (F3) was observed at Sampling Point 14N, located in an upland adjacent to Sampling Point 13. However, hydrophytic vegetation and wetland hydrology were absent at Sampling Point 14N.

Open Water
Open water features identified within the Delineation Area include two perennial ponds, which occur in the northwestern portion of the Delineation Area. These features are manmade impoundments of Morrison Creek. These features exhibit an OHWM and support hydrophytic vegetation along their fringes, while deeper portions are unvegetated. The vegetated fringes of the open water features are dominated by creeping spikerush and smartweed (Persicaria sp.). Sampling Point 11 was collected within an open water feature.

The soil matrix color at sampling point 11 was 7.5YR 4/1 with 30 percent redox concentrations colored 5YR 4/6. Soils at sampling point 11 met the criteria for hydric soil indicator Depleted Matrix (F3). Wetland ITEM 11.1. ATTACHMENT 4

hydrology indicators observed at Sampling Point 11 include Surface Water (A1), Water Marks (B1), Biotic Crust (B12), and Aquatic Invertebrates (B13). No wetland parameters were observed at Sampling Point 12N, located in an upland adjacent to Sampling Point 13.

5.0 JURISDICTIONAL ASSESSMENT
As per Regulatory Guidance Letter 16-01, an applicant may request a PJD “in order to move ahead expeditiously to obtain a Corps permit authorization where the requestor determines that it is in his or her best interest to do so ... even where initial indications are that the aquatic resources on a parcel may not be jurisdictional” (USACE 2016b). A significant nexus evaluation is not necessary to obtain a PJD. The following information on connectivity of wetlands and other waters in the Delineation Area to TNW is provided should an Approved Jurisdictional Determination be necessary.

The vernal pools, swales, and several stream/creek features within the Delineation Area flow directly or indirectly into Morrison Creek, or impoundments of Morrison Creek, along the northern boundary of the Delineation Area. Morrison Creek is a tributary to the Sacramento River. The USACE Sacramento District has identified the Sacramento River as TNW. Therefore, the aquatic resources within the Delineation Area likely have a significant nexus (affecting the chemical, physical, or biological integrity) with downstream TNW, and are likely subject to regulation under Section 404 of the CWA.

6.0 CONCLUSION
A total of 7.861 acres of aquatic resources have been mapped within the Delineation Area. This acreage represents a calculated estimation of the extent of aquatic resources within the Delineation Area, and is subject to modification following USACE review and/or the verification process. The placement of dredged or fill material into jurisdictional features would require a permit pursuant to Section 404 of the CWA and certification or waiver in compliance with Section 401 of the CWA.
