Data for Contra Costa County based on meteorological data collected from Chevron Refinery in 2005 Notes and References:

1. Emissions were developed using EMFAC2011 for fleet mix in 2014 assuming 10,000 AADT and includes impacts from diesel and gasoline vehicle exhaust, brake and tire wear, and resuspended dust.2. Roadways were modeled using CALINE4 air dispersion model assuming a source length of one kilometer. Meteorological data used to estimate the screening values are noted at the bottom of the “Re

3. Cancer risks were estimated for 70 year lifetime exposure starting in 2014 that includes sensitivity values for early life exposures and OEHHA toxicity values adopted in 2013.

Input the site-specific characteristics of your project by using the drop down menu in the “Search Parameter” box. We recommend that this analysis be used for roadways with 10,000 AADT and above.• County: Select the County where the project is located. The calculator is only applicable for projects within the nine Bay Area counties.• Side of the Roadway: Identify on which side of the roadway the project is located.• Distance from Roadway: Enter the distance in feet from the nearest edge of the roadway to the project site. The calculator estimates values for distances greater than 10feet and less than 1000 feet. For distances greater than 1000 feet, the user can choose to extrapolate values using a distribution curve or apply 1000 feet values for greater distances. When the user has completed the data entries, the screening level PM2.5 annual average concentration and the cancer risk results will appear in the Results Box on the right. Please note that the roadway tool is not applicable for California State Highways and the District refers the user to the Highway Screening Analysis Tool at: http://www.baaqmd.gov/Divisions/Planningand-Research/CEQA-GUIDELINES/Tools-and-Methodology.aspx Appendix A Page 119

https://ipac.ecosphere.fws.gov/location/H6ZGWVYLTZGFLLX2W2MFPOYRMI/resources 1/15 IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site-specific (e.g., vegetation/species surveys) and project-specific (e.g., magnitude and timing of proposed activities) information.

Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

This resource list is for informational purposes only and does not constitute an analysis of project level impacts.

The primary information used to generate this list is the known or expected range of each species.

Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site-specific and project-specific information is often required.

Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly.

For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following:

1. Draw the project location and click CONTINUE.

2. Click DEFINE PROJECT.

3. Log in (if directed to do so).

4. Provide a name and description for your project.

5. Click REQUEST SPECIES LIST.

Listed species and their critical habitats are managed by the Ecological Services Program of the U.S.

Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric Administration (NOAA Fisheries ).

Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list. Please contact NOAA Fisheries for species under their jurisdiction.

1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows species that are candidates, or proposed, for listing. See the listing status page for more information. IPaC only shows species that are regulated by USFWS (see FAQ).

2. NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the National Oceanic and Atmospheric Administration within the Department of Commerce.

The following species are potentially affected by activities in this location:

https://ipac.ecosphere.fws.gov/location/H6ZGWVYLTZGFLLX2W2MFPOYRMI/resources 8/15 Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report.

Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is

0.05/0.25 = 0.2.

3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

To see a bar's probability of presence score, simply hover your mouse cursor over the bar.

Breeding Season ( )
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.

The number of surveys is expressed as a range, for example, 33 to 64 surveys.

To see a bar's survey effort range, simply hover your mouse cursor over the bar.

No Data ( )
A week is marked as having no data if there were no survey events for that week.

Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development.

https://ipac.ecosphere.fws.gov/location/H6ZGWVYLTZGFLLX2W2MFPOYRMI/resources 13/15 Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool.

What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets .

Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.

How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:

1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);

2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and

3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing).

Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review.

Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.

https://ipac.ecosphere.fws.gov/location/H6ZGWVYLTZGFLLX2W2MFPOYRMI/resources 14/15 What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Wetlands in the National Wetlands Inventory
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes. 4/12/22, 8:39 AM IPaC: Explore Location resources
https://ipac.ecosphere.fws.gov/location/H6ZGWVYLTZGFLLX2W2MFPOYRMI/resources 15/15 For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District.

WETLAND INFORMATION IS NOT AVAILABLE AT THIS TIME
This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or for very large projects that intersect many wetland areas. Try again, or visit the NWI map to view wetlands at this location.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted.

Metadata should be consulted to determine the date of the source imagery used and any mapping problems.

Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site.

Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters.

Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory.

These habitats, because of their depth, go undetected by aerial imagery.

Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.

1 SUMMARY
On November 11, 2020, Olberding Environmental, Inc. conducted a field reconnaissance survey of the Skelly Property (Property) for the purpose of identifying sensitive plant and wildlife species, sensitive habitats, and biological constraints potentially occurring on the Property. The Property surveyed is comprised of approximately 7.49 acres located in the City of Hercules, Contra Costa County, California.

Results of the reconnaissance survey identified a small drainage feature at the southern portion of the property and two isolated seasonal wetlands that had developed in shallow topographical depressions associated with a horse paddock along the northern boundary. It was determined that these wetlands/waters might be considered jurisdictional by the U.S. Army Corps of Engineers (Corps), Regional Water Quality Control Board (RWQCB), and/or the California Department of Fish and Wildlife (CDFW). A jurisdictional delineation was prepared and presented to the Corps for verification purposes. Following an onsite verification, the Corps concluded that the perennial drainage was a jurisdiction feature. However, the two seasonal wetlands Were determined to be non-jurisdictional by the Corps due to their isolation and lack of connectivity to jurisdictional waters. Both the perennial drainage and the isolated wetlands qualify as jurisdictional “Waters of the State” by the RWQCB. The CDFW would have jurisdiction over the perennial drainage.

The proposed project would incorporate project design features to avoid the two seasonal wetlands. These design features include the creation of a bio retention basin surrounding the isolated wetlands with a 5-foot setback buffer to avoid impacts to the wetlands. Additionally, treated stormwater runoff water would be directed to the isolated wetlands from the retention basin, augmenting hydrology to support the functions and values being provided by the wetland habitat. The project will avoid the perennial drainage area entirely. There are no anticipated impacts to either the perennial drainage or the two seasonal wetlands. As such, no Corps, CDFW or RWQCB permits will be required.

A query of the California Natural Diversity Database (CNDDB) showed that thirteen specialstatus plant species have been recorded within a 5-mile radius of the Property. Eleven species were identified as having no potential to occur on the Property, based on the absence of suitable habitat, soil composition, and the development and disturbance of the Property. Suitable habitats for these species include vernal pool, serpentine environments, chaparral, broad-leafed upland forest, cismontane woodlands, coastal prairie, coastal scrub, freshwater wetland, brackish or freshwater marsh, none of which are found on the Property. Two plants, Diablo helianthella (Helianthella castanea) and Santa Cruz tarplant (Holocarpha macradenia) were both found to have marginally suitable habitat within the Property due to the presence of riparian woodland and grassland habitat with clay soils; however, it was determined that both species are not likely to occur on the Property due to the development and high level of disturbance historically to the 2 site through livestock activities such as grazing. In addition to the disturbance to the Property, the lack of nearby extant occurrences of Santa Cruz tarplant also made it unlikely that this species would occur onsite. For these reasons, a rare plant survey is not needed.

A total of four avian species were identified to have a high potential to occur on the Property.

The red-tailed hawk (Buteo jamaicensis), red-shouldered hawk (Buteo lineatus), Cooper’s hawk (Accipiter cooperii), and white-tailed kite (Elanus leucurus) all have a high potential to occur in both a foraging and nesting capacity. The red-tailed hawk was the only raptor observed foraging on or near the Property during the time of the survey. If project construction-related activities such as vegetation removal or grading take place during the nesting season (February through August), preconstruction surveys for nesting passerine birds and raptors are recommended.

No sign of bat use was observed on the Property during the November 2020 survey; however, based on habitat suitability, it was determined that bats have a moderate to high potential to utilize the site in a roosting and foraging capacity. These bat species include pallid bat (Antrozous pallidus), hoary bat (Lasiurus cinereus), Townsend’s big-eared bat (Corynorhinus townsendii), silver-haired bat (Lasionycteris noctivagans), and Yuma myotis (Myotis yumanensis). If project construction-related activities such as tree removal or the removal of the existing structures take place it is recommended that a bat habitat assessment is conducted by a qualified bat biologist during seasonal periods of bat activity to determine suitability of the onsite habitat. If special-status bat species are discovered, construction activities may be timed to minimize impacts and additional mitigation may be required.

CNDDB listed 8 occurrences of California red-legged frog (Rana draytonii) in the 5-mile radius of the Property. The potential seasonal wetland and perennial drainage on the Property do not provide suitable breeding habitat within the site. The Property contains suitable dispersal corridors and foraging habitat for CRLF; however, the closest occurrence of CRLF to the Property is approximately 1.5 miles east of the Property outside of the known 1-mile dispersal distance and separated by extensive residential development and Interstate 80. USFWS designated CRLF critical habitat is recorded 3.5 miles southeast of the Property, and the majority of the CNDDB occurrences are recorded in this region. For these reasons, CRLF has a low potential to occur on the Property and is not likely to occur.

The monarch butterfly (Danaus plexippus) was identified as having a moderate potential to overwinter on the Property. Monarchs generally overwinter beginning in September or October.

If project construction-related activities such as tree and vegetation removal take place during the overwintering season, preconstruction surveys for monarch butterfly are recommended during the months of September or October.
3 1.0 INTRODUCTION
Olberding Environmental, Inc. has conducted a biological resources analysis (biological constraints assessment) of the Skelly Property, located in the City of Hercules in Contra Costa County, California. This biological resources analysis included a review of pertinent literature on relevant background information and habitat characteristics of the site. Our review included researching existing information in the California Natural Diversity Database (CNDDB) maintained by the CDFW and the California Native Plant Society’s (CNPS) Inventory of Rare and Endangered Vascular Plants of California. Also included was a review of information related to species of plants and animals that could potentially utilize the described habitats identified on and immediately surrounding the Property. To assist in the assessment, a field reconnaissance investigation of the Property was conducted on November 11, 2020. This report documents the methods, results, and conclusions for the reconnaissance-level survey associated with the biological resources analysis for the Property.

2.0 LOCATION
The Property is located west of Interstate 80, and directly north of San Pablo Avenue in the city of Hercules, within Contra Costa County, California. Attachment 1, Figure 1 depicts the regional location of the Property in Contra Costa County, and Attachment 1, Figure 2 illustrates the vicinity of the Property in relationship to the City of Hercules. Attachment 1, Figure 3 identifies the location of the Property on the USGS 7.5 Quadrangle Map for Mare Island. An aerial photograph of the Property has been included as Attachment 1, Figure 4.

Access to the Property is provided from Highway 4. Traveling west on Highway 4, turn left onto San Pablo Avenue. Continue on San Pablo Avenue for 0.8 miles, and then take a right onto Hercules Avenue. Continue on Hercules Avenue for 0.2 miles, and then take a left onto Skelly.

Continue on Skelly for 0.2 miles and the Property will be at the terminus of the road.

3.0 PROPERTY DESCRIPTION
The Property encompasses approximately 7.49 acres in a roughly rectangular shape, bounded on all sides by residential housing. A concrete v-ditch approximately two feet wide lies along the north, east, and western perimeter of the site, outside of the Property boundary. This feature did not contain water during the time of the survey and was surrounded by ruderal grassland and eucalyptus woodland habitat and lined with native and ornamental trees which separate the Property from the adjacent residential housing. To the south of the Property lies railroad tracks and the Pinole Senior Center, and to the west, a public walking trail separates the Property from the adjacent Pinole Creek. The Property supports six habitat types: developed, ruderal grassland, perennial drainage, riparian woodland, eucalyptus woodland, and seasonal wetland habitat (Attachment 1, Figure 10).
4 The Property was previously a residence that contained numerous barns and paddocks for housing horses and other livestock. The Property still contains the residence and many of the barn structures, paddocks, and outbuildings, all of which are vacant. An asphalt and gravel driveway associated with the residence is present throughout the northeast corner of the Property, and remnants of old farm equipment and vehicles are found throughout the Property. Several large blue gum eucalyptus trees (Eucalyptus globulus) surround the driveway to the residence and many of the horse stalls on the Property. The residence and vacant structures are surrounded by ornamental vegetation and trees such as English ivy (Hedera helix), date palm (Phoenix sp.), olive (Olea europaea), pampas grass (Cortaderia selloana), English walnut (Juglans regius), blue gum eucalyptus, and Peruvian peppertree (Schinus molle). In addition to these structures, the Property contains a water storage tank located in the southwestern portion of the site, and a cell tower and associated utilities located in the southeastern corner of the Property.

Much of the ruderal grassland habitat throughout the site is located in areas once used as paddocks, and these locations have been regularly disturbed for over twenty years through both grazing and livestock activity as observed through analysis of aerial imagery (Google Earth 2020). The majority of the ruderal grassland habitat has been disked recently, with patches of ruderal vegetation scattered throughout, and concentrated along the margins of the habitat. The remaining vegetation is dominated by wild oat (Avena fatua), barbed wild oat (Avena barbata), field bindweed (Convolvulus arvensis), ripgut brome (Bromus diandrus), bristly ox-tongue (Helminthotheca echioides), soft chess (Bromus hordeaceus), and a mix of other non-native species.

A perennial drainage feature is found along the southern boundary of the site, and enters from the southeastern corner, flowing west and exiting the Property via a culvert near the southwestern corner. This feature was surrounded by a mix of native and non-native riparian vegetation such as English walnut, eucalyptus, Himalayan black berry (Rubus armeniacus), northern California black walnut (Juglans hindsii), California buckeye (Aesculus californica), and Lombardy poplar (Populus nigra). This feature contained water throughout much of its length and had a defined bed and bank.

Two seasonal wetlands were located along the northern boundary of the Property adjacent to an old horse stall and paddock. Dominant species include common plantain (Plantago major), annual beard grass (Polypogon monspeliensis), Bermuda grass (Cynodon dactylon), and bristly oxtongue.

The topography of the Property is relatively flat with a gentle slope near the southeastern corner, and ranges between 9 feet above sea level at the northwestern boundary and 53 feet above sea level near the southeastern boundary.
5 4.0 REGULATORY SETTING

4.1 Federal Regulatory Setting

4.1.1 Plants and Wildlife
The federal Endangered Species Act (ESA) of 1973 (16 USC 1531 et seq., as amended) prohibits federal agencies from authorizing, permitting, or funding any action that would result in biological jeopardy to a plant or animal species listed as Threatened or Endangered under the Act. Listed species are taxa for which proposed and final rules have been published in the Federal Register (U.S. Fish and Wildlife Service [USFWS] 2020). If a proposed project may jeopardize listed species, Section 7 of the ESA requires consideration of those species through formal consultations with the USFWS. Federal Proposed species (USFWS, 2019) are species for which a proposed listing as Threatened or Endangered under ESA has been published in the Federal Register. If a proposed project may jeopardize proposed species, Section 7 of the ESA affords consideration of those species through informal conferences with USFWS. The USFWS defines federal Candidate species as “those taxa for which we have on file sufficient information on biological vulnerability and threats to support issuance of a proposed rule to list, but issuance of the proposed rule is precluded by other higher priority listing actions” (USFWS, 2019).

Federal Candidate species are not afforded formal protection, although USFWS encourages other federal agencies to give consideration to Candidate species in environmental planning.

4.1.2 Wetlands/Waters
The federal government, acting through the Corps and the Environmental Protection Agency (EPA), has jurisdiction over all “waters of the United States” as authorized by §404 of the Clean Water Act (CWA) and §10 of the Rivers and Harbors Act of 1899 (33 CFR Parts 320-330).

Properties that cause the discharge of dredged or fill material into waters of the United States require permitting by the Corps. Actions affecting small areas of jurisdictional waters of the United States may qualify for a Nationwide Permit (NWP), provided conditions of the permit are met, such as avoiding impacts to threatened or endangered species or to important cultural sites.

Properties that affect larger areas or which do not meet the conditions of an NWP require an Individual Permit. The process for obtaining an Individual Permit requires a detailed alternatives analysis and development of a comprehensive mitigation/monitoring plan.

On January 23, 2020 the EPA and the Corps enacted the Navigable Waters Protection Rule (NWPR) to redefine “waters of the United States” to include four categories. Their landward extent was defined following the definitions provided in the Corps of Engineers regulations [33 CFR §328.3]:
6 (a) Jurisdictional waters. The Clean Water Act defines “waters of the United States” as:
(1) The territorial seas, and waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including waters which are subject to the ebb and flow of the tide;
(2) Tributaries;
(3) Lakes and ponds, and impoundments of jurisdictional waters; and (4) Adjacent wetlands.

Wetlands are transitional habitats between upland terrestrial areas and deeper aquatic habitats such as rivers and lakes. Adjacent wetlands are wetlands that abut, meaning to touch at least at one point or side of, jurisdictional waters or are inundated by flooding from jurisdictional waters in a typical year (33 CFR Section 328 (c)(1)). Under federal regulation, wetlands are defined as “those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal conditions do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (33 CFR Section 328 (c)(16)).

Swamps, marshes, bogs, fens, and estuaries are all defined as wetlands, as are seasonally saturated or inundated areas such as vernal pools, alkali wetlands, seeps, and springs. In addition, portions of the riparian habitat along a river or stream may be a wetland where the riparian vegetation is at or below the ordinary high-water mark and thus also meets the wetland hydrology and hydric soil criteria.

Navigable waters include all waters subject to the ebb and flow of the tides, including the open ocean, tidal bays, and tidal sloughs. Navigable waters also include some large, non-tidal rivers and lakes, which are important for transportation in commerce. The jurisdictional limit over navigable waters extends laterally to the entire water surface and bed of the waterbody landward to the limits of the mean high tide line. For non-tidal rivers or lakes, which have been designated (by the Corps) to be navigable waters, the limit of jurisdiction along the shoreline is defined by the ordinary high-water mark. Ordinary high-water mark is that 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 (33 CFR Section 328(c)(7)). The Corps regulates other waters to the outward limit of the ordinary high-water mark. Streams should exhibit a defined channel, bed and banks to be delineated as other waters.

The 2020 NWPR defines non-jurisdiction waters as:
(1) Waters or water features that are not identified in (a)(1) through (4) above; 7 (2) Groundwater, including groundwater drainage through subsurface drainage systems;
(3) Ephemeral features, including ephemeral streams, swales, gullies, rills, and pools; (4) Diffuse stormwater run-off and direction sheet flow over upland; (5) Ditches that are not territorial seas or traditional navigable waters, or tributaries, and those portions constructed in adjacent wetlands that do not satisfy the conditions of adjacent wetlands;
(6) Prior converted cropland;
(7) Artificially irrigated areas, including fields flooded for agricultural production, that would revert to upland should application of irrigation water to that area cease;
(8) Artificial lakes and ponds, including water storage reservoirs and farm, irrigation, stock watering, and clog cleaning ponds, constructed of excavated in upland or in non-jurisdictional waters, so long as those artificial lakes and ponds are not impoundments of jurisdictional waters that meet the conditions of lakes and ponds, and impoundments of jurisdictional waters;
(9) Water-filled depressions constructed or excavated in upland or in nonjurisdictional waters incidental to mining or construction activity, and pits excavated in upland or in non-jurisdictional waters for the purpose of obtaining fill, sand, or gravel;
(10) Stormwater control features constructed of excavated in upland or in nonjurisdictional waters to convey, treat, infiltrate, or store stormwater run-off; (11) Groundwater recharge, water reuse, and wastewater recycling structures, including detention, retention, and infiltrations basins and ponds, constructed or excavated in upland or in non-jurisdictional waters; and (12) Waste treatment systems.

However, the preamble also states “the Corps reserves the right on a case-by-case basis to determine that a particular waterbody within these categories” can be regulated as jurisdictional water. The EPA also has authority to determine jurisdictional waters of the U.S. on a case-bycase basis. Riparian habitat that is above the ordinary high-water mark and does not meet the three-parameter criteria for a wetland would not be regulated as jurisdictional waters of the United States, but is regulated by CDFW.
8 4.1.3 Migratory Bird Treaty Act
Raptors are migratory bird species protected by international treaty under the Migratory Bird Treaty Act (MBTA) of 1918 (16 U.S.C. 703-711). The MBTA makes it unlawful to take, possess, buy, sell, purchase, or barter any migratory bird listed in 50 CFR. Part 10, including feathers or other parts, nests, eggs, or products, except as allowed by implementing regulations (50 CFR 21). Sections 3503, 3503.5, and 3800 of the California Fish and Game Code prohibit the take, possession, or destruction of birds, their nests or eggs. Implementation of the take provisions requires that Property-related disturbance at active nesting territories be reduced or eliminated during critical phases of the nesting cycle (generally February 1 – September 1, annually). Disturbance that causes nest abandonment and/or loss of reproductive effort (e.g., killing or abandonment of eggs or young) or the loss of habitat upon which the birds depend, is considered “taking” and is potentially punishable by fines and/or imprisonment. Such taking would also violate federal law protecting migratory birds (e.g., MBTA).

4.1.4 Federal Bald and Golden Eagle Protection Act
In addition to protection under the MBTA, both the bald eagle and the golden eagle are also protected by the Bald and Golden Eagle Protection Act of 1940 (16 U.S.C. 668-668c). The Bald and Golden Eagle Protection Act, and amended several times since being enacted in 1940, prohibits anyone, without a permit issued by the Secretary of the Interior, from “taking” bald or golden eagles, including their parts, nests, or eggs (USFWS 2007). The Act provides criminal penalties for persons who “take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner, any bald eagle ... [or any golden eagle], alive or dead, or any part, nest, or egg thereof.” The Act defines “take” as “pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, molest or disturb” (USFWS 2007).

For purposes of these guidelines, “disturb” means: “to agitate or bother a bald or golden eagle to a degree that causes, or is likely to cause, based on the best scientific information available, 1) injury to an eagle, 2) a decrease in its productivity, by substantially interfering with normal breeding, feeding, or sheltering behavior, or 3) nest abandonment, by substantially interfering with normal breeding, feeding, or sheltering behavior” (USFWS 2007).

In addition to immediate impacts, this definition also covers impacts that result from humaninduced alterations initiated around a previously used nest site during a time when eagles are not present, if, upon the eagle’s return, such alterations agitate or bother an eagle to a degree that interferes with or interrupts normal breeding, feeding, or sheltering habits, and causes injury, death or nest abandonment (USFWS 2007).
9 4.2 State Regulatory Setting

4.2.1 Plants and Wildlife
Property permitting and approval requires compliance with California Environmental Quality Act (CEQA), the 1984 California Endangered Species Act (CESA), and the 1977 Native Plant Protection Act (NPPA). The CESA and NPPA authorize the California Fish and Game Commission to designate Endangered, Threatened and Rare species and to regulate the taking of these species (§§2050-2098, Fish & Game Code). The California Code of Regulations (Title 14, §670.5) lists animal species considered Endangered or Threatened by the State.

The Natural Heritage Division of the CDFW administers the state rare species program. The CDFW maintains lists of designated Endangered, Threatened, and Rare plant and animal species (CDFW 2020b and 2019). Listed species either were designated under the NPPA or designated by the Fish and Game Commission. In addition to recognizing three levels of endangerment, the CDFW can afford interim protection to candidate species while they are being reviewed by the Fish and Game Commission.

The CDFW also maintains a list of animal species of special concern (CDFW 2019), most of which are species whose breeding populations in California may face extirpation. Although these species have no legal status, the CDFW recommends considering them during analysis of proposed property impacts to protect declining populations and avoid the need to list them as endangered in the future.

Under provisions of §15380(d) of the CEQA Guidelines, the CEQA lead agency and CDFW, in making a determination of significance, must treat non-listed plant and animal species as equivalent to listed species if such species satisfy the minimum biological criteria for listing. In general, the CDFW considers plant species on List 1A (Plants Presumed Extinct in California), List 1B (Plants Rare, Threatened, or Endangered in California and elsewhere), or List 2 (Plants Rare, Threatened, or Endangered in California, But More Common Elsewhere) of the CNPS Inventory of Rare and Endangered Vascular Plants of California (Skinner and Pavlik 1994) as qualifying for legal protection under §15380(d). Species on CNPS Lists 3 or 4 may, but generally do not, qualify for protection under this provision.

Sensitive habitats include riparian corridors, wetlands, habitats for legally protected species and CDFW Species of Special Concern, areas of high biological diversity, areas providing important wildlife habitat, and unusual or regionally restricted habitat types. Habitat types considered sensitive include those listed on the CNDDB working list of “high priority” habitats (i.e., those habitats that are rare or endangered within the borders of California) (Holland 1986). 10 4.2.2 Wetlands/Waters
The RWQCB regulates activities in wetlands and other waters through §401 of the Clean Water Act. Section 401 requires a state water quality certification for properties subject to 404 regulations. Requirements of the certification include mitigation for loss of wetland habitat. In the San Francisco Bay region, the RWQCB may identify additional wetland mitigation beyond the mitigation required by the Corps. California Fish and Game Code §§1600-1607 require the CDFW be notified of any activity that could affect the bank or bed of any stream that has value to fish and wildlife. Upon notification, the CDFW has the discretion to execute a Streambed Alteration Agreement. The CDFW defines a stream as follows:
“... a body of water that flows at least periodically...through a bed or channel having banks and supporting fish and other aquatic life. This includes watercourses having a subsurface flow that supports or has supported riparian vegetation.” (Source: Streambed Alteration Program, California Department of Fish and Wildlife, 2016).

In practice, CDFW authority is extended to any “blue line” stream shown on a USGS topographic map, as well as unmapped channels with a definable bank and bed. Wetlands, as defined by the Corps, need not be present for CDFW to exert authority.

4.2.3 California Environmental Quality Act
According to Appendix G of the CEQA (CEQA 2020) Guidelines, a proposed project would have a significant impact on biological resources if it would:
a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the CDFW and USFWS? b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the CDFW or USFWS?
c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
11 e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan?

4.2.4 City of Hercules Municipal Code
According to the City of Hercules Municipal Code, Title 4. Public Welfare, Morals, and Conduct, the removal of mature trees is prohibited from any undeveloped or partially developed property, whether public or private, within the City of Hercules for any reason. Some exceptions apply (Ord. 331 § 1 (part), 1996).

Definitions for the above terms:
(a) “Mature tree” includes any living tree with a trunk diameter measuring twelve (12) inches or greater when measured at “breast height,” which is roughly four and one-half (4-1/2) feet above the surface of the ground.
(b) “Tree removal” shall include any one or more of the following:
(1) Complete removal of a mature tree.
(2) Any action foreseeably leading to the death of a mature tree or permanent damage to its health.
(3) Removal of more than one-third (1/3) of the foliage of a mature tree, except where such removal of foliage is necessary for periodic maintenance appropriate to the particular tree species in question.
(c) “Undeveloped or partially developed property” includes all properties which are available for future development or redevelopment but does not include developed residential or nonresidential properties. (Ord. 331 § 1 (part), 1996) Exemptions to the above municipal code are as follows:

Section 4-15.04
(a) If a mature tree poses an immediate and substantial threat to the safety of persons or property, the property owner may contact the Public Works Director and request approval to remove the tree. After consultation with the City Manager if at all possible, the Public Works Director shall confirm that an emergency situation exists. The Public Works 12 Director may then authorize removal. The Public Works Director may consult with a certified arborist if deemed necessary to confirm the necessity for tree removal. The removal of a mature tree under emergency conditions with approval by the Public Works Director shall be reported to the City Council at the next regularly scheduled City Council meeting (4-15.04).

Section 4-15.05 Tree Removal In Conjunction with Development Mature trees may be removed in conjunction with development projects for which the City has issued all necessary land use approvals, provided however, that the City approves, and the developer implements a tree replacement plan. In addition, mature trees may be removed in conjunction with development projects for which the California Department of Toxic Substances Control, U.S. Army Corps of Engineers and/or the California Department of Fish and Game has issued a permit, provided that the following conditions are satisfied:
(a) The property owner has obtained and is in compliance with a Grading Permit and Erosion and Sediment Control Plan pursuant to Chapter 7-2 of this Code; (b) The City has approved and the property owner is implementing a tree replacement plan as part of an environmental mitigation program approved by the applicable state or federal agency; and
(c) The proposed pre-development activities are consistent with the City’s General Plan, as determined by the Community and Business Development Director. (Ord. 331 § 1 (part), 1996)
Violation of any of the provisions of this Chapter or the knowing or intentional misrepresentation to any officer or employee of the City of any material fact when requesting tree removal under Sections 4-15.04 or 4-15.05 shall constitute a misdemeanor punishable by a fine of not more than One Thousand Dollars ($1,000), or by imprisonment for a period not to exceed six (6) months, or by both such fine and imprisonment. (Ord. 331 § 1 (part), 1996).

5.0 METHODS OF ANALYSIS FOR GENERAL BIOLOGICAL RESOURCES A special-status plant and wildlife species database search and review was conducted using the CNDDB and other sources. An additional search was conducted for special-status plants using CNPS Inventory on-line. Special-status species reports were accessed by searching the CNDDB database for the Mare Island, Sears Point, Cuttings Wharf, Cordelia, Benicia, Briones Valley, Richmond, San Quentin, and Petaluma Point USGS 7.5-minute quadrangles which surround the Property, and by examining those species that have been identified in the vicinity of the Property. These quadrangles will be henceforth noted as surrounding quads. The database report identified special-status species known to occur in the region or those that have the potential to 13 occur in the vicinity of the Property. The CNDDB report was used to focus special-status species analysis of the site prior to the reconnaissance surveys.

Olberding Environmental biologists conducted a reconnaissance-level survey of the Property on November 11, 2020. The survey consisted of walking throughout the Property and evaluating the site and adjacent lands for potential biological resources. Existing conditions observed plants and wildlife, adjacent land use, soils and potential biological resource constraints were recorded during the visit. Plant and wildlife species observed within and adjacent to the Property during the reconnaissance survey are listed in Attachment 2, Table 1. Site photographs are provided in Attachment 3 of this document. Attachment 1, Figure 9 shows where each site photo was taken.

The objectives of the field survey were to determine the potential presence or absence of specialstatus species habitat listed in the CNDDB database report and to identify any wetland areas that could be potentially regulated by the Corps, RWQCB, and/or CDFW (CNDDB 2020). In addition, the Olberding Environmental biologists looked for other potential sensitive species or habitats that may not have been obvious from background database reports or research. Surveys conducted after the growing season or conducted outside of the specific flowering period for a special-status plant cannot conclusively determine the presence or absence of such plant species; therefore, site conditions and habitat type were used to determine potential for occurrence. When suitable habitat was observed to support a special-status plant or animal species, it was noted in the discussion for that particular species. Regulatory agencies evaluate the possibility of occurrence based on habitats observed on-site and the degree of connectivity with other specialstatus animal habitats in the vicinity of the Property. These factors are discussed in each specialstatus plant or animal section. Potential for occurrence of each special-status or protected plant and animal species was evaluated using the following criteria. • Present: The species has been recorded by CNDDB or other literature as occurring on the Property and/or was observed on the Property during the reconnaissance survey or protocol surveys.
• May Occur: The species has been recorded by CNDDB or other literature as occurring within five miles of the Property, and/or was observed within five miles of the Property, and/or suitable habitat for the species is present on the Property or its immediate vicinity. • Not Likely to Occur: The species has historically occurred on or within five miles of the Property, but has no current records. The species occurs within five miles of the Property but only marginally suitable habitat conditions are present. The Property is likely to be used only as incidental foraging habitat or as an occasional migratory corridor. • Presumed Absent: The species will not occur on the Property due to the absence of suitable habitat conditions, and/or the lack of current occurrences. Alternatively, if 14 directed or protocol-level surveys were done during the proper occurrence period and the species was not found, it is presumed absent.

Sources consulted for agency status information include USFWS (2020) for federally listed species and CDFW (2019) for State of California listed species. Based on information from the above sources, Olberding Environmental developed a target list of special-status plants and animals with the potential to occur within or in the vicinity of the Property (Attachment 2, Table 2).

5.1 Soils Evaluation
The soils present on a property may determine if habitat on the site is suitable for certain specialstatus plants and animals. The host plants of some special-status invertebrates may also require specific soil conditions. In the absence of suitable soil conditions, special-status plants or animals requiring those conditions would be presumed absent. Information regarding soil characteristics for the Property was obtained by viewing the Natural Resources Conservation Service (NRCS) Web Soil Survey report for the Property (NRCS 2020).

5.2 Plant Survey Methods
The purposes of the botanical surveys were (1) to characterize the habitat types (plant communities) of the study area; (2) to determine whether any suitable habitat for any specialstatus plant species occurs within the study area; and (3) to determine whether any sensitive habitat types (wetlands) occur within the study area. Site conditions and plant habitat surveys are important tools in determining the potential occurrence of plants not recorded during surveys (e.g., special-status plants) because presence cannot conclusively be determined if field surveys are conducted after the growing season or conducted outside a specific flowering period.

5.2.1 Review of Literature and Data Sources
The biologists conducted focused surveys of literature and special-status species databases in order to identify special-status plant species and sensitive habitat types with potential to occur in the study area. Sources reviewed included the CNDDB occurrence records (CNDDB 2020) and CNPS Inventory (Skinner and Pavlik 1994) for the surrounding quads; and standard flora (The Jepson Manual 2012). From the above sources, a list of special-status plant species with potential to occur in the Property vicinity was developed (Attachment 2, Table 2).

5.2.2 Field Surveys
Biologists from Olberding Environmental conducted a reconnaissance-level survey to determine habitat types and the potential for special-status plants based on the observed habitat types. All 15 vascular plant species that were identifiable at the time of the survey were recorded and identified using keys and descriptions in The Jepson Manual (2012).

The habitat types occurring on the Property were characterized according to pre-established categories. In classifying the habitat types on the site, the generalized plant community classification schemes of A Manual of California Vegetation (Sawyer, Keeler-Wolf, and Evens 2009) were consulted. The final classification and characterization of the habitat types of the study area were based on field observations.

5.3 Wildlife Survey Methods
The purposes of the wildlife survey were to identify special-status wildlife species and/or potential special-status wildlife habitats within the study area.

5.3.1 Review of Literature and Data Sources
A focused review of literature and data sources was conducted in order to determine which special-status wildlife species had potential to occur in the vicinity of the Property. Current agency status information was obtained from USFWS (2020) for species listed as Threatened or Endangered, as well as Proposed and Candidate species for listing, under the federal ESA; and from CDFW (2020b, 2019) for species listed as Threatened or Endangered by the state of California under the CESA or listed as “species of special concern” by CDFW. From the above sources, a list of special-status wildlife species with potential to occur in the Property vicinity was developed (Attachment 2, Table 2).

5.3.2 Field Surveys
General Wildlife Survey – Olberding Environmental biologists conducted a survey of species habitat within the entire study area, including visible portions of the adjacent properties. The purpose of the habitat survey was to evaluate wildlife habitats and the potential for any protected species to occur on or adjacent to the Property.

Reconnaissance-Level Raptor Survey – A reconnaissance-level raptor survey was conducted on the Property. Observation points were established on the periphery of the site to view raptor activity over a fifteen- to thirty-minute time period. This survey was conducted with the use of binoculars and notes were taken for each species occurrence. Additionally, utility poles and perch sites in the vicinity of the Property were observed. All raptor activity within and adjacent to the Property was recorded during the reconnaissance-level observation period.

Reconnaissance-Level Burrowing Owl (Athene cunicularia) Survey – A reconnaissance-level burrowing owl (Athene cunicularia) survey was also conducted on the Property to identify 16 potential burrow sites or burrowing owl use of on-site habitat. The general presence and density of suitable burrow sites (e.g., rodent burrows) was evaluated for the Property.

6.0 RESULTS FOR GENERAL BIOLOGICAL RESOURCES
The search and review of the CNDDB database reports revealed the occurrence of special-status plant and wildlife species that occur in the habitats found within the Property boundaries (CNDDB 2020). The CNDDB database and background data were reviewed for the surrounding quads. Animal occurrences shown on Attachment 1, Figure 5 and plant occurrences shown on Attachment 1, Figure 6 are located within 5 miles of the Property and were reviewed for their potential to occur on the Property based on general habitat types. Results of the species review are tabulated on Attachment 2, Table 2. Critical habitat within the surrounding quads is shown on Attachment 1, Figure 7.

6.1 Soil Evaluation Results
The NRCS (2020) reports three soil types within the Property. A map of the soil types can be found in Attachment 1, Figure 8. The soil type mapped included the following:
• Cc: Clear Lake Clay, 0 to 15 percent slopes – Clear Lake clay soils can be found at elevations between 25 and 2,000 feet with 0 to 2 percent slopes. The composition of this soil type within the Property consists of 85 percent Clear Lake and similar soils, and 15 percent of minor components including Pescadero (4%), Cropley (4%), Conejo (4%), and Unnamed (3%).

The Clear Lake series consists of very deep, poorly drained soils that formed in fine textured alluvium derived from sandstone and shale. Clear Lake soils are in basins and in swales of drainageways. Clear Lake soils exhibit slow to very slow permeability and negligible to high runoff (if assumed concave runoff is always negligible). These soils are used for growing many row crops such as tomatoes, beans and sugar beets, dry farmed to grain, or irrigated and dry farmed pasture, and for rangeland. Native vegetation consists of grasses and forbs. This series shows no frequency of ponding or flooding and is nonsaline. A water table is at depths of 4 to 10 feet in the late summer and in some areas is very near the surface during the wet months of winter. Some areas are artificially drained. Its stratified layers consist of the following (colors are for dry soil unless otherwise stated):

Ag--0 to 13 inches; dark gray clay, very dark gray moist; very hard, firm; neutral (pH

7.0).

Bssg1--13 to 19 inches; dark gray clay, very dark gray moist; extremely hard, very firm; moderately alkaline (pH 8.0).
17 Bssg2--19 to 45 inches; dark gray clay, very dark gray moist; extremely hard, very firm; moderately alkaline (pH 8.0).

Bssk--45 to 60 inches; grayish brown clay, light olive brown moist; very hard, very firm; moderately alkaline (pH 8.0).
• LcE: Lodo Clay Loam, 9 to 30 percent slopes– The Lodo Clay Loam series consists of somewhat excessively drained soils with a parent material of residuum weathered from sandstone and shale. These soils are found on steep hills at elevations of 300 to 3,000 feet. This soil type has no frequency of flooding or ponding. The composition of this soil type within the Property consists of 85 percent Lodo and similar soils and 15 percent of minor components including Millsholm (5%), Los Osos (5%), Tiera (3%), and Rock Outcrop (2%).

A--0 to 7 inches; grayish brown shaly clay loam, very dark grayish brown moist; weak fine subangular blocky structure; slightly acid.

R--7 inches; shattered warped and folded dark grayish brown hard shale. • CoE: Cut and Fill Land – Millsholm Complex, 9-30 percent slopes – The composition of this soil type within the Property consists of 75 percent cut and fill land (fill part, which is composed of 0-60 inches of silty clay loam), 15 percent Millsholm and similar soils, and 10 percent of minor components including Lodo (5%), Gilroy (3%), and Los Gatos (2%). This soils type has a parent material of residuum weathered from sandstone and shale. This soil type never experiences flooding or ponding and has a very low water capacity.

6.2 Plant Survey Results

6.2.1 Floristic Inventory and Habitat Characterization
The Property supports six habitat types consisting of developed habitat, potential seasonal wetlands, a perennial drainage, riparian woodland, eucalyptus woodland, and ruderal grassland.

In classifying the habitat types on the Property, generalized plant community classification schemes were used (Sawyer, Keeler-Wolf, and Evens 2009). The final classification and characterization of the habitat type of the Property was based on field observations. Plant species that occurred within 5 miles of the Property are shown in Attachment 1, Figure 6.

The habitat type and a description of the plant species present within the habitat type are provided below. The habitats found on the Property are mapped on Attachment 1, Figure 10. 18 Dominant plant species are also noted. A complete list of plant species observed on the Property can be found within Attachment 2, Table 1.

Developed
The existing residence, outbuildings, water storage tank, cell tower, and driveway comprise 1.94 acres of developed habitat. The residence and outbuildings are surrounded by fallow grass lawns and cultivated ornamental trees and shrubs such as date palm, giant yucca (Yucca gigantea), English ivy, weeping willow (Salix babylonica), olive, Peruvian peppertree, blue gum eucalyptus, English walnut, pampas grass, and coast redwood (Sequoia sempervirens). The large water storage tank and cell tower are surrounded by ruderal grassland habitat.

Perennial Drainage
The perennial drainage feature is located along the southern boundary of the Property and contained water throughout the majority of its length. Dominant species observed include Himalayan blackberry, and English ivy. The westernmost stretch of this feature did not contain surface water; however, this section was dominated by hydrophytic species such as narrowleaved cattail (Typha angustifolia), and umbrella sedge (Cyperus eragrostis). This feature was surrounded by riparian woodland habitat. Figure 10 indicates Perennial Drainage (0.10 AC, 454 LNFT).

Potential Seasonal Wetland
Two seasonal wetlands comprising approximately 0.034 acres, were located along the northern boundary of the Property. Dominant vegetation observed within this section includes but is not limited to bristly ox-tongue, annual beard grass, salt grass (Distichlis spicata), and common plantain (Plantago major).

Riparian Woodland
The riparian woodland habitat is approximately 0.17 acres and is located along the southern boundary of the site and surrounds the perennial drainage feature on the Property. This habitat is dominated by a mix of both native and non-native trees such as blue gum eucalyptus, coast redwood, California buckeye, English walnut, northern California black walnut, Lombardy poplar, arroyo willow (Salix lasiolepis), and red willow (Salix laevigata).

Eucalyptus Woodland
The eucalyptus woodland habitat within the Property is comprised of approximately 0.83 acres of large blue gum eucalyptus trees. Numerous eucalyptus trees line the driveway to the Property and are also found surrounding the developed and riparian woodland habitat near the southern boundary of the site.
19 Ruderal Grassland
A majority of the Property (4.40 acres) is characterized by ruderal grassland habitat that has been disturbed by past grazing and livestock activities, and recent land management practices such as disking for weed abatement. In the areas where disking has occurred, little to no living vegetation was observed. The remaining ruderal grasslands occurred in areas that were previously used as paddocks or grazing land for horses and other livestock. Dominant vegetation includes non-native annual grasses such as wild oat, Johnsongrass, soft chess (Bromus hordeaceus) and other bromes (Bromus spp.). Additional species observed include alkali mallow (Malvella leprosa), prickly lettuce (Lactuca serriola), and clover (Trifolium hybridum). Several large trees are present along the western boundary of the Property within the ruderal grassland habitat and consist of species such as English walnut and California buckeye.

Special-Status Plant Species
Special-status plant species include species listed as Rare, Threatened, or Endangered by the USFWS (2020) or by the State of California (CDFW 2020b). Federal Proposed and Candidate species (USFWS, 2019) are also special-status species. Special-status species also include species listed on List 1A, List 1B, or List 2 of the CNPS Inventory (Skinner and Pavlik, 1994; CNPS 2020). All species in the above categories fall under state regulatory authority under the provisions of CEQA and may also fall under federal regulatory authority. Considered special-status species are species included on List 3 (Plants About Which We Need More Information—A Review List) or List 4 (Plants of Limited Distribution—A Watch List) of the CNPS Inventory.

These species are considered to be of lower sensitivity and generally do not fall under specific state or federal regulatory authority. Specific mitigation considerations are not generally required for List 3 and List 4 species.

Attachment 2, Table 2 includes a list of special-status plants with the potential to occur within or in the immediate vicinity of the Property based on a review of the surrounding quads. The special-status plant species identified by the CNDDB as potentially occurring on the Property are known to grow only from specific habitat types. The specific habitats or “micro-climate” necessary for many of the plant species to occur are not found within the boundaries of the Property. The habitats necessary for the CNDDB reported plant species consist of valley and foothill grassland, cismontane woodlands, closed-cone coniferous forest, chaparral, playas, chenopod scrub, alkaline soils, serpentine soils, alkali flats, flooded lands, coastal prairie, coastal scrub, coastal salt marsh, vernal pools, seeps, meadows and sinks, swamps, freshwater or brackish marsh, cismontane woodlands, freshwater wetlands, oak woodlands, and broad-leafed upland forest. Occurrence distance from the Property is estimated from this center point (Attachment 1, Figure 6).

A query of the California Natural Diversity Database (CNDDB) showed that thirteen specialstatus plant species occur in a 5-mile radius of the Property. The majority of these species were 20 identified as having no potential to occur on the Property based on the absence of suitable habitat, soil composition, and the development and disturbance of the Property. Suitable habitats for these species include vernal pool, serpentine environments, chaparral, broad-leafed upland forest, cismontane woodlands, coastal prairie, coastal scrub, freshwater wetland, brackish or freshwater marsh, none of which are found on the Property. The Property contains ruderal grassland, developed, riparian woodland, seasonal wetland, perennial drainage, and eucalyptus woodland habitats that are frequently disturbed by human activity and livestock grazing.

Additionally, the frequent tilling throughout the Property for weed abatement and property maintenance makes it highly unlikely for these species to occur, particularly those relying on vernal pools or grassland habitat. For these reasons, it is unlikely that these special status plant species would occur.

Two species that had one or more occurrences within the immediate vicinity of the Property are discussed in detail below.

Diablo Helianthella (Helianthella castanea). CNPS List 1B.

Diablo helianthella is a perennial that exhibits yellow sunflowers that bloom between April and June. The plant has simple broad leaves that are attached at the base of the stem and grows up to two feet in height. The Diablo helianthella is known to grow on open grassy sites in cismontane woodland and closed-cone coniferous forests.

CNDDB listed eight occurrences within five miles of the Property. The closest occurrence (Occurrence # 106) was observed approximately 3.0 miles south of the Property in 2007. The exact location was unknown; therefore, the occurrence was broadly documented as occurring within Pinole Valley Park, with an unspecified number of plants collected from the hillside and canyon above Wright Road. The most recent occurrence (Occurrence # 87) was documented approximately 5.0 miles southeast of the Property, near Pinole Peak, north of Pinole Creek in 2014. In this occurrence, numerous plants were observed in the region dating back to 1993, with three plants observed in a very small portion of the range in 2014. No plants were observed at the time of the November survey. The Property contains ruderal grassland habitat, as well as a perennial drainage which is surrounded by riparian woodland habitat consisting of a mixture of native and non-native trees. Diablo helianthella prefers rocky axonal soil; however, the soils present on the Property contain high clay content with areas of sandstone and shale alluvium, making the soils within the Property less suitable habitat. Additionally, the Property was historically used for housing livestock such as horses, and many areas of the Property were either developed or utilized as grazing pastures for these livestock leading to a high level of disturbance to the site. For these reasons, Diablo helianthella is not likely to occur on the Property. 21 Santa Cruz Tarplant (Holocarpha macradenia). Federally Threatened, State Endangered, CNPS List 1B.

Santa Cruz tarplant is an annual herb of the Asteraceae family. It is found along coastal terraces in Alameda, Contra Costa, Monterey, Marin and Santa Cruz Counties. It is found in coastal prairie and valley and foothill grassland habitats in sandy clay soils, often amongst non-native plants. Yellow flowers bloom between June and October.

CNDDB listed nine occurrences (Occurrence # 16, 27, 28, 29, 35, 36, 38, 39, and 44) within five miles of the Property. Occurrences 16, 27, 36, and 39 are all extirpated, and 35 and 42 are likely extirpated as well. The only extant populations (#28, 29) are on located approximately 4.0 to 4.5 miles from the Property on protected lands. Occurrence #28 was recorded in Wildcat Canyon Regional Park, 1.0 mile east of Hillview School, approximately 4.0 miles south of the Property.

In this occurrence, 203 plants were observed on a west-facing slope in association with nonnative avena and bromus grass species in 2009. Occurrence #29 was recorded on the Mezue Trail, 1.5 miles east of Hillview School, in Wildcat Canyon Regional Park, approximately 4.5 miles south of the Property. In this occurrence, 401 plants were observed in 2009. No plants were observed at the time of the November survey. Santa Cruz tarplant prefers coastal prairie, coastal scrub, and valley grassland habitat; however, the Property contains ruderal grassland habitat that has been historically disturbed by human disturbance such as disking for weed management, as well as livestock activity such as grazing. The Property does contain marginally suitable soil for this species with its high clay and sand content, however due to the extensive disturbance and development to the Property, along with the lack of nearby extant populations, it is not likely that Santa Cruz tarplant would occur on the Property.

6.3 Wildlife Survey Results

6.3.1 General Wildlife Species and Habitats
A complete list of wildlife species observed within the Property can be found in Attachment 2, Table 1. Wildlife species commonly occurring within habitat types present on the Property are discussed below:

Developed
The Property contains a vacant residence along with numerous out buildings and barns, many of which contained openings that could provide opportunities for numerous species of wildlife to utilize these structures for shelter or nesting purposes. Several horse stalls on the Property appeared to have evidence of old nests along the walls, potentially made by species such as black phoebes (Sayornis nigricans). Additionally, the large open barns on the Property contained evidence of white wash from birds perching along the rafters, and this structure could also 22 provide nesting opportunities for owl species such as the barn owl (Tyto alba). In addition to avian species, these vacant structures could provide roosting opportunities for numerous structure-roosting bat species such as the Yuma myotis (Myotis yumanensis), pallid bat (Antrozous pallidus), and Towsend’s big-eared bat (Corynorhinus townsendii). Other species observed within the developed habitat include several domestic cats (Felis catus).

The Property also contained a gravel and asphalt driveway surrounded by ornamental plants, and a fallow lawn associated with the residence. The large ornamental trees surrounding the structures could provide nesting opportunities for numerous avian species, as well as roosting opportunities for foliage roosting bat species such as the hoary bat (Lasiurus cinereus). Avian species observed foraging in the developed habitat include bushtits (Psaltriparus minimus) and dark-eyed junco (Junco hyemalis).

Ruderal Grassland
The majority of the Property consists of ruderal grassland habitat, much of which appears to have been that has been recently disked leading to reduced vegetation throughout this habitat.

Passerine species observed during the survey include lesser goldfinch (Spinus psaltria), goldencrowned sparrow (Zonotrichia atricapilla), white-crowned sparrow (Zonotrichia leucophrys), and western bluebird (Sialia mexicana). Other avian species observed include American crow (Corvus bracyrynchos), and turkey vulture (Cathartes aura). The red-tailed hawk (Buteo jamaicensis) was the only raptor species observed during the survey.

Small mammal burrows were observed throughout the Property, belonging to small rodent species such as the California vole (Microtus californicus) and mice (Peromyscus spp.).

The ruderal grassland habitat, along with the cover from old farm equipment and debris could offer suitable habitat for various reptile species such as western fence lizard (Sceloporus occidentalis), and pacific gopher snake (Pituophis catenifer catenifer).

Drainage
The perennial drainage along the southern boundary of the Property contained water throughout much of its length, which could provide numerous foraging opportunities to a number of species.

The wetted sections of the drainage could provide potential habitat for amphibian species such as Sierran treefrogs (Pseudacris sierra). Additionally, the drainage may support an array of insects, allowing for abundant foraging opportunities for various bat and passerine species. Species observed in this habitat include black phoebe (Sayornis nigricans), ruby-crowned kinglet (Regulus calendula), and spotted towhee (Pipilo maculatus). 23 Potential Seasonal Wetland
Two seasonal wetlands occur along the northern boundary of the Property and did not contain surface water during the time of the survey. These features could provide an abundance of insects and additional vegetative cover that could provide foraging opportunities for a variety of passerines and during the wet season. Species observed utilizing the potential seasonal wetland habitat include the lesser goldfinch.

Riparian Woodland
The riparian woodland habitat along the southern boundary of the Property provides numerous foraging and nesting opportunities for many avian and foliage roosting bat species. The mature trees, and dense, shrubby understory provide an abundance of nesting opportunities for a variety of avian species. Species observed utilizing this habitat include yellow-rumped warbler (Setophaga coronata), chestnut-backed chickadee (Poecile rufescens), hairy woodpecker (Leuconotopicus villosus), Nuttall’s woodpecker (Picoides nuttallii), northern flicker (Colaptes auratus), and cedar waxwings (Bombycilla cedrorum). Eastern fox squirrels (Sciurus niger) were also observed nesting and foraging in this habitat.

Eucalyptus Woodland
The large eucalyptus trees within this habitat provides suitable nesting habitat for a variety of raptor species. In addition to avian species, this habitat could also provide suitable overwintering habitat for monarch butterflies.

BIRDS
Red-Tailed Hawk (Buteo jamaicensis). State Protected.

The red-tailed hawk is a large Buteo that is distinct due to the red color of its tail feathers in contrast to the brown color of its body. Not all red-tailed hawks exhibit the distinct coloration on their tail and gradations may occur especially in young birds. Red-tailed hawks hunt rodents by soaring over grassland habitat. Nest trees for red-tailed hawks are usually tall trees with a welldeveloped canopy that includes a strong branching structure on which to build a nest.

The CNDDB does not track occurrences of red-tailed hawk; however, several red-tailed hawks were observed foraging in the area during the November survey. No large stick nests were observed on the Property; however, the Property contains numerous large trees such as the blue gum eucalyptus, that would make for suitable nesting habitat within the Property. In addition, foraging opportunities occur along the ruderal grassland habitat due to the abundance of small mammals. Given the information above the red-tailed hawk has high potential to occur on the Property in a nesting capacity and is present in a foraging capacity. 24 Red-shouldered Hawk (Buteo lineatus). State Protected.

The red-shouldered hawk is a medium-sized, slender Buteo with long legs and a long tail and is smaller than the red-tailed hawk. Upperparts are dark with pale spotting, and rusty-reddish feathers on the wing create the distinctive shoulder patch. The tail has several wide, dark bars; the intervening narrow stripes and the tip of the tail are white, and there is variation in the number of tail bars among adults and juveniles. The habitat that the red-shouldered hawk prefers varies from bottomland hardwoods and riparian areas to upland deciduous or mixed deciduousconifer forest, and almost always includes some form of water, such as a swamp, marsh, river, or pond. In the west, the red-shouldered hawk sometimes occurs in coniferous forests, and has been expanding its range of occupied habitats to include various woodlands, including stands of eucalyptus trees amid urban sprawl. They typically place their nests in a broad-leaved tree (occasionally in a conifer), below the forest canopy but toward the tree top, usually in the crotch of the main trunk. Nest trees are often near a pond, stream, or swamp, and can be in suburban neighborhoods or parks. These hawks eat mostly small mammals, lizards, snakes, and amphibians. They also eat toads, snakes, and crayfish. They occasionally eat birds, sometimes from bird feeders; recorded prey includes sparrows, starlings, and doves.

The CNDDB does not track occurrences of red-shouldered hawk. The large trees present within the riparian and eucalyptus woodland offer suitable nesting habitat. Additionally, the abundance of small mammals within the ruderal grassland habitat on the Property provides numerous foraging opportunities. Given the information above the red-shouldered hawk has high potential to occur on the Property in a nesting and foraging capacity.

Cooper’s Hawk (Accipiter cooperii). State Protected.

Coppers’ hawk is a medium to large-size raptor, reaching an average of 28-34 in wingspan. They are distinctive for the black and white horizontal banding on the elongated tail, blue gray head, back and upperwings. Rusty red horizontal barring on a white breast. Large square head. Long yellow legs and feet. Cooper’s hawk hunt in woodlands, riparian areas, and can even be observed hunting in densely vegetated urban areas for small birds, rodents and reptiles. Specialists at hunting avian prey, Copper’s hawk often hunt along the edges of woodlands, shorelines, and riparian habitats where migrating passerines typically occur. Cooper’s hawk typically nests within the vegetation of tall trees near riparian habitat and nesting habitat for these raptors consists of woodlands, coniferous forest, and dense oak woodland.

CNDDB listed one occurrence (Occurrence #70) of Cooper’s hawk within the vicinity of the Property. In this occurrence, numerous adults along with a nest and one fledgling were observed in 1999, south of Franklin Canyon Road, east of Hercules, approximately 3.5 miles east of the Property. No Cooper’s hawks were observed during the November survey; however, the Property contains suitable nesting habitat due to the abundance of large trees within the site, and numerous foraging opportunities exist throughout the Property due to the abundance of small 25 birds present throughout the site. Given the information above the Cooper’s hawk may occur in both a nesting and foraging capacity.

White-tailed Kite (Elanus leucurus). Federal Species of Concern, CDFW: Fully Protected.

The white-tailed kite is falcon-shaped with a long white tail. This raptor has black patches on the shoulders that are highly visible while the bird is flying or perching, long, pointed gray wings, and deep red eyes with black eye ring. This species forages in annual grasslands, farmlands, orchards, chaparral, and at the edges of marshes and meadows. They are found nesting in trees and shrubs such as willows (Salix sp.), California sycamore (Platanus racemosa), and coast live oak (Quercus agrifolia) often near marshes, lakes, rivers, or ponds. This raptor often hovers while inspecting the ground below for prey. The white-tailed kite eats mainly small mammals, as well as some birds, lizards, and insects. Annual grasslands are considered good foraging habitat for white-tailed kites, which will forage in human-impacted areas.

CNDDB did not list any nearby occurrences of white-tailed kite within the vicinity of the Property; however, the Property contains suitable foraging habitat throughout the ruderal grassland due to the abundance of small mammals, and the riparian and eucalyptus woodland habitat onsite provide suitable nesting habitat. Given the information above the white-tailed kite may occur in both a nesting and foraging capacity.

San Pablo Song Sparrow (Melospiza melodia samuelis). California Species of Special Concern.

The San Pablo song sparrow is a song sparrow subspecies that is endemic to the tidal saltmarshes surrounding North San Francisco Bay and San Pablo Bay. These birds utilize habitat with California cord grass, pickleweed, and gumplant. They require sites with dense vegetation for nesting, for song perches, and for cover from predators.

CNDDB listed six occurrences (Occurrence #9, 26, 29, 30, 37, and 42) of San Pablo song sparrow within five miles of the Property. The majority of these occurrences are historical (occurring 20 or more years ago). Occurrence #30 is the closest record to the Property, and the Property lies within the boundary of this occurrence. This record is a historical occurrence from specimens collected in 1947. The exact location of the specimen collection is unknown, and was mapped roughly to a salt marsh 4.0 miles north of Richmond. The most recent occurrence (Occurrence # 9) is documented approximately 4.5 miles northeast of the Property, at the southwestern tip of Mare Island, southwest of Vallejo. In this occurrence, 130 adults were detected in April and May in 2004. No San Pablo song sparrows were observed during the November survey. The San Pablo song sparrow’s range is restricted mainly to the fringes of the San Pablo Bay portion of the San Francisco Bay estuary (Shuford and Gardali, 2008). The Property did not contain California chordgrass, pickleweed, or gumplant vegetation which this species prefers, and it lacked the tidal saltmarsh habitat necessary for foraging and nesting. 26 Although Occurrence #30 overlaps with the Property boundary, this historical record was an approximation, with a maximum error distance of up to 1.0 mile. Additionally, since the collection of this specimen in 1947, the surrounding area has been developed extensively by both residential and commercial development which could create potential barriers to the dispersal of this species onto the Property from the more suitable tidal marsh habitat north of the site. For these reasons, the San Pablo song sparrow is presumed absent from the Property.

Swainson’s Hawk (Buteo swainsoni). State Threatened.

The Swainson’s hawk is a raptor that is slightly smaller than the red-tailed hawk with long wings that taper slightly toward the outer wing tip. This hawk has a brown bib that covers its head and extends down the chest. The leading portion of the wing is light in color. In flight, this bird has an inverse color pattern in comparison to a red-tailed hawk. This hawk has three potential color morphs---light, intermediate and dark. Swainson’s hawks are summer migrants to the Central Valley and Delta region where they nest within larger-sized trees.

CNDDB did not list any occurrences of Swainson’s hawks within a five-mile radius of the Property, however there were eight occurrences of this species documented in the surrounding quadrants. This species was not observed during the November survey. The Property contained suitable nesting trees for Swainson’s hawk with the numerous large eucalyptus trees; however, the site is less suitable for nesting due to the high level of urbanization and disturbance within and surrounding the Property. Swainson’s hawks prefer to forage in open fields, agricultural areas, and sites with an abundance of small mammals. The surrounding areas are largely developed, with residential and commercial buildings, and the ruderal grassland habitat within the Property provides only marginally suitable foraging habitat. For these reasons and due to the lack of nearby nesting occurrences, the Swainson’s hawk is not likely to occur on the Property.

MAMMALS
Special-status Bats
Bats (Order - Chiroptera) are the only mammals capable of “true” flight. They are nocturnal feeders and locate their prey, which consists of small to medium sized insects by echolocation.

Bats consume vast amounts of insects making them very effective pest control agents. They may eat as much as their weight in insects per day. Maternity roosts comprised of only females, may be found in buildings or mine shafts with temperatures up to 40 degrees Celsius and a high percentage of humidity to ensure rapid growth in the young. Female bats give birth to only one or two young annually and roost in small or large numbers. Males may live singly or in small groups, but scientists are still unsure of the whereabouts of most males in summer. 27 Special-status bats with the potential to occur on the Property are listed below:
• Hoary bat (Lasiurus cinereus)
• Silver-haired bat (Lasionycteris noctivagans)
• Pallid bat (Antrozous pallidus)
• Yuma myotis (Myotis yumanensis)
• Townsend’s big-eared bat (Corynorhinus townsendii)
CNDDB listed one occurrence (Occurrence #139) of pallid bat within 5-miles of the Property. In this historical occurrence, recorded in 1937, several specimens were collected from an unknown location mapped approximately to an area west of Pinole at sea level, approximately 4.0 miles east of the Property. In addition to this occurrence, CNDDB listed several occurrences of Townsend’s big-eared bat, hoary bat, pallid bat, and silver-haired bat in the surrounding 9 quadrants. No bats, or sign of bat occupation was observed during the November survey; however, the site contains an abundance of suitable roosting habitat throughout the Property. The large trees present throughout the site contain dense foliage, peeling bark, and tree cavities, all of which provide roosting opportunities for foliage and cavity roosting species such as the hoary bat, Yuma myotis, and silver-haired bat. The Property also contains numerous vacant structures which could provide roosting habitat for structure roosting species such as Townsend’s big-eared bat, pallid bat, and Yuma Myotis. Additionally, the grassland, perennial drainage, and riparian habitats provide an array of insects, allowing for abundant foraging opportunities throughout the site. Given the above information, Yuma myotis, hoary bat, pallid bat, and Townsend’s big-eared bat have a high potential to occur on the Property in both a roosting and foraging capacity, while the silver-haired bat has a moderate potential to occur in both a roosting and foraging capacity.

AMPHIBIANS
California Red-Legged Frog (Rana draytonii). Federally Threatened, California Species of Special Concern.

California red-legged frog (CRLF) was listed as a Federal threatened species on May 31, 1996 (61 FR 25813) and is considered threatened throughout its range. If a proposed Property may jeopardize listed species, Section 7 of the ESA requires consideration of those species through formal consultations with the USFWS. Federal Proposed species (USFWS 2006c) are species for which a proposed listing as Threatened or Endangered under the ESA has been published in the Federal Register. If a proposed Property may jeopardize proposed species, Section 7 of the ESA affords consideration of those species through informal conferences with USFWS. On April 13, 2006, USFWS designated critical habitat for the CRLF under the ESA. In total, approximately 450,288 acres fell within the boundaries of critical habitat designation. A new ruling by the USFWS on March 17, 2010, revised the designation of critical habitat for CRLF (75 FR 12815 12959). In total, approximately 1,636,609 acres of critical habitat in 27 California 28 counties fall within the boundaries of the final revised critical habitat designation. This rule became effective on April 16, 2010.

The CRLF is a rather large frog, measuring one and a half to five inches in length. They are reddish-brown to gray in color, with many poorly defined dark specks and blotches. Dorsolateral folds are present. The underside of the CRLF is washed with red on the lower abdomen and hind legs. The CRLF has a dark mask bordered by a light stripe on the jaw, smooth eardrums, and not fully webbed toes. The male has enlarged forearms and swollen thumbs. Its vocals consist of a series of weak throaty notes, rather harsh, and lasting two to three seconds. Breeding occurs from December to March with egg masses laid in permanent bodies of water.

The CRLF is found in lowlands, foothill woodland and grasslands, near marshes, lakes, ponds or other water sources. These amphibians require dense shrubby or emergent vegetation closely associated with deep still or slow-moving water. Generally, these frogs favor intermittent streams with water at least two and a half feet deep and where the shoreline has relatively intact emergent or shoreline vegetation. CRLF is known from streams with relatively low gradients and those waters where introduced fish and bullfrogs are absent. CRLF are known to take refuge upland in small mammal burrows during periods of high-water flow. CRLF occurs west of the Sierra Nevada-Cascade and in the Coast Ranges along the entire length of the state. Historically, they occurred throughout the Central Valley and Sierra Nevada foothills south to northern Baja California. Now they are found from Sonoma and Butte Counties south to Riverside, but mainly in Monterey, San Luis Obispo, and Santa Barbara Counties.

CNDDB listed 8 occurrences of the CRLF occurring within five miles of the Property, with the majority of these occurrences recorded southeast of Interstate 80 within the USFWS designated critical habitat for CRLF (Unit D02D) (Attachment 1, Figure 7). The closest occurrence (Occurrence #407) is approximately 1.5 miles east of the Property. In this occurrence, two adults and nine juveniles were observed in a tributary to Refugio Creek, southeast of the intersection of Interstate 80 and Highway 4, in 2000. The most recent occurrence (Occurrence #1113) was documented in 2008 approximately 4.5 miles southeast of the Property. The perennial drainage and potential seasonal wetland features on the Property, do not offer suitable habitat to support breeding for this species due to the lack of deep ponding water onsite. Additionally, the closest occurrence of CRLF is approximately 1.5 miles from the Property, which is outside of the onemile dispersal range known for this species. The site contains wetted riparian habitat which could provide adequate shelter, foraging opportunities, and predator avoidance for this species; however, the closest occurrence is located outside the known dispersal distance for this species, and is separated from the Property by extensive residential development, roads, and Interstate 80, all of which could be potential barriers to the dispersal of CRLF onto the Property from more suitable breeding habitat elsewhere. For these reasons, CRLF is not likely to occur on the Property.
29 INVERTEBRATES
Monarch Butterfly (Danaus plexippus). Winter Roost Sites State Protected.

The monarch butterfly is identified by its bright orange color. The wings have a wide black border and black veins. The apex and borders of the wings contain white spots and the wingspan is approximately three to four inches. This species of butterfly ranges from southern Canada throughout the United States, Central and South America. Each autumn (August through October) monarch butterflies migrate south to overwinter in massive aggregations in coastal California and in central Mexico. Monarchs typically reach their overwintering grounds by September or October. Monarchs select overwintering sites based on protection from high wind and storms, absence of freezing temperatures, presence of spatially variable light such as full sun, shade, and dappled sunlight, the presence of high humidity, and availability of water. These aggregations of sometimes millions of individuals can be found in sheltered groves of trees such as eucalyptus, Monterey Pine and cypress. The host plant of the monarch butterfly is the milkweed (Ascelepius sp.). Eggs are laid on the underside of the leaves. Upon hatching, the larvae feed on the poisonous host plant, storing these toxins as protection from predators.

Monarch butterfly overwintering sites are protected in California.

CNDDB listed one occurrence (Occurrence #24) of a monarch butterfly overwintering site within five miles of the Property. In this occurrence, a population of overwintering monarchs was observed within blue gum eucalyptus trees at Point Pinole Regional Shoreline from 1980 to 2011, approximately 3.5 miles west of the Property. The Property contains plenty of blue gum eucalyptus trees that would provide suitable habitat for overwintering monarchs. For these reasons, the monarch butterfly has a moderate potential to occur on the Property.

7.0 CONCLUSIONS

7.1 Wetlands
Results of the biological resource analysis survey conducted by Olberding Environmental indicate that the Property contains wetlands/waters considered jurisdictional by the Corps, RWQCB or CDFW. The Property has a perennial drainage feature, and two isolated seasonal wetlands. The Corp has determined that they would only have jurisdiction over the perennial drainage feature. Similarly, the CDFW would only have jurisdiction over the drainage and associated riparian habitat. However, the RWQCB would regulate both the perennial drainage and isolated seasonal wetland features. a. Site development would avoid all three jurisdictional features and incorporate avoidance and project design features such as setback buffers and augmentation of hydrology, to protect and maintain the drainage and wetlands.. 30 7.2 Special-status Plants
No special-status plant species were determined to have a potential to occur on the Property.

This was based on the frequent disturbance by livestock activity and land management practices within the Property, as well as the absence of suitable habitats and soil types, and nearby or recent CNDDB occurrences.

7.3 Special-status Wildlife
Foraging or Nesting Raptor/Passerine Species – A total of four bird species were identified as having potential to occur on the Property. Red-tailed hawk, red-shouldered hawk, white-tailed kite, and Cooper’s hawk had a high potential to occur on the Property in both a nesting and foraging capacity. The red-tailed hawk was the only raptor species observed foraging on the Property during the time of the survey.

Special-Status Mammals – Given the presence of suitable onsite habitat; the pallid bat, hoary bat, Townsend’s big-eared bat, silver-haired, and Yuma myotis have a high to moderate potential to occur on the Property in a foraging and roosting capacity. No immediate signs of bats were present during the initial survey but the large redwood, eucalyptus, and palm trees, as well as the vacant residence, barns, and outbuildings within the Property could provide potential roosting habitat.

Special-Status Amphibians – CNDDB lists 8 occurrences of CRLF and USFWS designated critical habitat within the vicinity of the Property. The Property contains potential seasonal wetlands and a perennial drainage feature; however, they do not provide suitable breeding habitat for this species. The Property contains marginally suitable foraging and dispersal habitat for this species, although the closest occurrence is outside of the one-mile dispersal distance for CRLF.

For these reasons, CRLF is not likely to occur on the Property.

Special-Status Invertebrates– CNDDB lists one occurrence of a monarch butterfly overwintering site within the vicinity of the Property. The Property contains suitable overwintering habitat with the presence of eucalyptus woodland and the presence of water within the site. For these reasons, monarch butterfly has a moderate potential to overwinter on the Property.

8.0 RECOMMENDATIONS
• Pre-Construction Avian Survey – If project construction-related activities would take place during the nesting season (February through August), preconstruction surveys for nesting passerine birds and raptors (birds of prey) within the Property should be conducted by a competent biologist 14 days prior to the commencement of the tree removal or site grading activities. If any bird listed under the Migratory Bird Treaty Act 31 is found to be nesting within the project site or within the area of influence, an adequate protective buffer zone should be established by a qualified biologist to protect the nesting site. This buffer shall be a minimum of 75 feet from the project activities for passerine birds, and a minimum of 200 feet for raptors. The distance shall be determined by a competent biologist based on the site conditions (topography, if the nest is in a line of sight of the construction and the sensitivity of the birds nesting). The nest site(s) shall be monitored by a competent biologist periodically to see if the birds are stressed by the construction activities and if the protective buffer needs to be increased. Once the young have fledged and are flying well enough to avoid project construction zones (typically by August), the project can proceed without further regard to the nest site(s). • Pre-construction Bat Survey – To avoid “take” of special–status bats, the following mitigation measures shall be implemented prior to the removal of any existing trees or structures on the project site:
a) A bat habitat assessment shall be conducted by a qualified bat biologist during seasonal periods of bat activity (mid–February through mid–October – ca. Feb. 15 – Apr. 15, and Aug. 15 – October 30), to determine suitability of each existing structure as bat roost habitat.
b) Structures found to have no suitable openings can be considered clear for project activities as long as they are maintained so that new openings do not occur. c) Structures found to provide suitable roosting habitat, but without evidence of use by bats, may be sealed until project activities occur, as recommended by the bat biologist.

Structures with openings and exhibiting evidence of use by bats shall be scheduled for humane bat exclusion and eviction, conducted during appropriate seasons, and under supervision of a qualified bat biologist.
d) Bat exclusion and eviction shall only occur between February 15 and April 15, and from August 15 through October 30, in order to avoid take of non–volant (non–flying or inactive, either young, or seasonally torpid) individuals.

OR
A qualified wildlife biologist experienced in surveying for and identifying bat species should survey the portion of the Property with large trees and abandoned structures. If tree removal is proposed to determine if any special–status bats reside in the trees. Any special–status bats identified should be removed without harm. Bat houses sufficient to shelter the number of bats removed should be erected in open space areas that would not be disturbed by project development.
32 • Monarch Butterfly Survey – The monarch butterfly arrives at California overwintering sites in September and October. Due to the CNDDB occurrence of an overwintering site within a five-mile radius of the Property, an overwintering monarch survey is recommended in late September or the month of October to confirm the presence or absence of overwintering monarch butterflies on the Property. • Riparian Habitat Replacement - Riparian woodland habitat exists along a perennial drainage located along the southern boundary of the project site. Native tree species such as California buckeye, California black walnut, and willow species are present throughout this habitat. If removal of any trees deemed “protected” by the City of Hercules Municipal Code (Title 4, Chapter 15 – Removal of Mature Trees) from the riparian habitat during project activities were to occur, all ordinances and codes must be adhered to. An arborist report may be necessary to determine the identity of trees planned for removal or alteration, the impact of alteration, and measures that may be required to address tree removal if tree removal should occur. The City requires a tree replacement plan to be submitted and approved prior to any tree removal. Olberding Environmental recommends that all trees over 12 diameters at breast height (DBH) in size slated for removal shall be replaced at a 3:1 ratio of 15-gallon trees. 15-gallon containers have been in the pots/nursery for the least amount of time and have the greatest potential to have well formed, but not defective, root system. Adherence to Title 4, Chapter 15 - Removal of Mature Trees of the City of Hercules Municipal Code would result in a less than significant impact to riparian habitat or other sensitive natural community. • Biological Monitoring - Wildlife exclusion fencing shall be installed around the perimeter of the work area in order to prevent native and migratory wildlife species from entering the project site during construction activities. Daily biological monitoring during initial grubbing and weekly checks of wildlife exclusion fencing after initial grubbing has concluded. These monitoring activities will be conducted by a qualified biologist having local wildlife experience. Daily wildlife surveys would be included. All contractors and construction crews working onsite will receive environmental and biological sensitivity training in order to reduce or avoid effects on covered species during construction activities.
• Erosion Control – Grading and excavation activities could expose soil to increased rates of erosion during construction periods. During construction, runoff from the Property could adversely affect aquatic life within the adjacent water features. Surface water runoff could remove particles of fill or excavated soil from the site, or could erode soil down-gradient, if the flow were not controlled. Deposition of eroded material in adjacent water features could increase turbidity, thereby endangering aquatic life, and reducing wildlife habitat. Implementation of appropriate mitigation measures would ensure that impacts to aquatic organisms would be avoided or minimized. Mitigation measures may 33 include use of best management practices (BMP’s) such as hay bales, silt fencing, placement of straw mulch and hydro seeding of exposed soils after construction as identified in a project Storm Water Pollution Prevention Plan (SWPPP). 34 9.0 LITERATURE CITED
