Methodology
Background research for the project included a literature review of documents previously prepared for the Termino Avenue Drain Replacement Project in Alamitos Bay (EDAW 2006, 2007, 2009). Prior to conducting fieldwork, AECOM biologists reviewed regional biological resource information provided by the California Natural Diversity Database (CNDDB) (CDFW 2015) and the California Native Plant Society’s (CNPS) inventory of rare and endangered vascular plants of California. This allowed the biologists to prepare a list of potentially occurring plant and animal species of concern. On July 16, 2015, a visit to the Alamitos Bay Discharge Pipe site was conducted by scientific divers Michael Ireland and Alonso Gonzalez Cabello, and biologist Barbra Calantas. This visit included vegetation/land cover mapping, general wildlife surveys, general plant surveys, and a marine survey. A formal jurisdictional determination of U.S. Army Corps of Engineers (USACE) jurisdiction was not conducted.
Vegetation on the project site was mapped onto an aerial photograph of the site; results were transferred to geographic information system (GIS) software to calculate acreages.
General wildlife surveys were conducted by walking wandering transects of the terrestrial portion of the project site while recording all observed wildlife species. In addition, all suitable nesting areas (e.g., trees, bushes, and building eves) within 500 feet were surveyed for active bird nests. All bird species observed during this survey were recorded (Attachment 1).
General plant surveys involved searching for target sensitive species expected in the region by walking meandering transects through all habitats on the project site. The only potentially occurring sensitive plant species, the estuary seablite ( Suaeda esteroa; CNPS Plant List 1B.2), flowers from May to October, but predominantly in the late summer (Ferren 1993), and may not have been detectable so early in the flowering period.
Marine surveys involved conducting SCUBA surveys at low tide when the in-water area of the project site was no deeper than 12 feet. Prior to surveying the area, the in-water corners of the project site were identified and marked with floats using global positioning system (GPS) technology. Scientific divers conducted a preliminary examination of the area by swimming along the bottom across the entire in-water area observing subtidal habitat including any rooted subtidal vegetation or anchored macroalgae. Once the general extents of subtidal habitat were identified, scientific divers swam the perimeter of any distinct habitat types and used floating GPS technology to record a track of these edges. These data were transferred to GIS to calculate acreages. All observed marine species were recorded during these surveys (Attachment 1).

Vegetation Communities and Other Cover Types
The project site is characterized by four distinct vegetation communities and land cover types: open water, eelgrass bed, sand, and developed. These are described in more detail below and are displayed in Figure 2. Photographs of the representative habitat types are provided in Attachment 2 and the photo locations are displayed in Figure 3.
Open Water
The open water portion of the study area is within Alamitos Bay, used for recreational boating and swimming. Open water habitats on-site include sand and subtidal soft bottom.
This vegetation community and the associated acreage calculations include the area from mean sea level to the in-water extents of the project boundary. Approximately 0.14 acre (6,203 square feet) of open water habitat occurs on-site (Figure 2).
Eelgrass
The only subtidal habitats noted within the project site were bare ground (open water) and eelgrass, a flowering subtidal grass. The subtidal soft bottom and protection within Alamitos Bay provide ideal habitat for eelgrass beds. Eelgrass is a flowering marine plant that forms meadows in Southern California embayments. This species of eelgrass grows in Alamitos Bay between the ocean entrance channel and Marine Stadium at depths between 0 feet mean lower low water (MLLW) and -12 feet MLLW. Figure 2 maps the existing eelgrass in the project footprint and in a 50-foot buffer of the project footprint. 1 Eelgrass vegetation was mapped using a GPS unit and a team of two snorkeling biologists. Approximately 0.005 acre (224 square feet) of eelgrass habitat occurs within the project footprint (Figure 2). An additional 0.06 acre (2,584 square feet) of eelgrass habitat occurs within a 50-foot buffer of the project footprint (Figure 2).
Beach (64400)
Beaches include sandy and/or cobbly habitat on coastal strands, lagoons, or lakes. Ocean beaches are a shoreline feature of deposited sand formed by waves and tides off the coast.
Beaches on lakes may be a result of waves, disturbance, or geological formations. Beaches are mainly unvegetated areas; however, upper portions may be thinly populated with herbaceous species (Holland 1986). The unvegetated beach area on-site is heavily used for recreational purposes and is manicured by the City of Long Beach using grading tractors.
Approximately 0.19 acre (8,489 square feet) of beach occurs on-site (Figure 2; Photos 3 and 6).
1 A 50-foot buffer of the project footprint was established in all subtidal areas where it was safe for scientific divers to enter. A portion of the subtidal area buffer to the southeast of the footprint was inaccessible due to recreational boat activity and the presence of a boat dock. This area is not included in the report or on report maps. This buffer was mapped to aid in assessment of indirect impacts caused by the implemented Project per the California Eelgrass Mitigation Policy and Implementing Guidelines (NOAA NMFS 2014).

Developed
Developed areas include the beach parking lot, the pump station building and fenced yard, a boat shed, and the pipe outfall structure. There are no native or exotic plant species in the developed areas. Approximately 0.12 acre (5,309 square feet) of developed area occurs on-site (Figure 2).
Sensitive Biological Resources
Special-status species considered in this report include species listed or proposed for listing as endangered or threatened under the federal Endangered Species Act (ESA) (USFWS 2015), the California ESA (CDFW 2015b), or the California Native Plant Protection Act. Also included are species of special concern to the California Department of Fish and Wildlife (CDFW 2015b); species on CNPS lists 1A, 1B, and 2; species covered under the Migratory Bird Treaty Act (MBTA); and species covered under the Marine Mammal Protection Act (MMPA). In addition, habitats covered by the Magnuson–Stevens Fishery Conservation and Management Act (MFCMA) were considered. For this report, all birds in the sensitive species list are protected under the MBTA.
Marine Habitat – Eelgrass Beds
Approximately 0.005 acre (224 square feet) of eelgrass habitat occurs in the project footprint, with an additional 0.06 acre (2,584 square feet) occurring within 50 feet of the project footprint (Figure 2). Alamitos Bay is considered Essential Fish Habitat (EFH), defined as “those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity” (16 U.S. Code 1802[10]) under the MFCMA. The proposed project is located within an area designated as EFH for one Fisheries Management Plan (FMP), the Coastal Pelagics Management Plan. Although not observed during eelgrass surveys, of the 86 species managed under all of the FMP, four are known to occur in the San Pedro Channel area and potentially within Alamitos Bay: northern anchovy, Pacific sardine, Pacific mackerel, and jack mackerel (EDAW 2009).
The eelgrass canopy (consisting of shoots and leaves approximately 2 to 3 feet long) attracts many marine invertebrates and fishes, and the added vegetation and vertical relief it provides enhances the abundance and diversity of marine life compared to areas where the sediments are barren. The vegetation also serves a nursery function for many juvenile fish and invertebrates, including species of commercial and/or sports fish value (California spiny lobster, California halibut, and barred sand bass). A diverse community of bottom-dwelling invertebrates (i.e., clams, crabs, and worms) lives within the soft sediments that cover the root and rhizome mass system. Eelgrass meadows are also critical foraging centers for seabirds (such as the endangered California least tern) that seek out baitfish (i.e., juvenile topsmelt) attracted to the eelgrass cover. Eelgrass is an important contributor to the detrital (decaying organic) food web of bays, as the decaying plant material is consumed by many benthic invertebrates (such as polychaete worms) and reduced to primary nutrients by bacteria.

Wildlife
The project study area includes a variety of marine and bird species. During the general wildlife and marine surveys, nine bird species and eight marine species were detected in the project site, or within a 500-foot radius of the project site for birds. A faunal inventory was compiled of species encountered or detected during the surveys and is included in Attachment 1.
A CNDDB search of the project site and a 5-mile radius of the site resulted in 21 sensitive animal species known to occur in the general project area. In addition, two pinniped species covered by the MMPA were also considered. All sensitive wildlife species that have a potential to occur on the site are listed in Attachment 3, including their sensitivity status, habitat requirements, and probabilities for occurrence. None of these sensitive species have been observed directly in the project area. Among these 23 species, three have a moderate potential to occur, five have a low potential to occur, five have a very low potential to occur, and 10 are not expected to occur on the project site. Of the four federal or state threatened or endangered wildlife species that have a potential to occur within the project area based on the proximity of known habitats or populations, one has a low potential to occur and three have a very low potential to occur.
Invertebrates
No listed or nonlisted sensitive invertebrate species were determined to have a high or moderate potential to occur on the project site. Information about invertebrate species that were determined to have a low potential to occur or very low potential to occur, or are not expected to occur on the site is provided in Attachment 3.
Reptiles
No listed or nonlisted sensitive reptile species were determined to have a high or moderate potential to occur on the project site. Information about reptile species that were determined to have a low potential to occur or very low potential to occur, or are not expected to occur on the site is provided in Attachment 3.
Birds
No birds protected under the MBTA were observed exhibiting nesting or courtship behavior.
Ornamental eucalyptus and palm trees adjacent to the site may provide potential nesting habitat for small raptors and cavity nesting birds (Photos 4 and 5). Among listed and nonlisted sensitive bird species, only the delisted federal and state endangered California brown pelican (Pelecanus occidentalis), now a California Department of Fish and Wildlife (CDFW) Species of Special Concern, was determined to have a moderate potential to occur on the project site. The California brown pelican is discussed below. Information about bird species that were determined to have a low potential to occur or very low potential to occur, or are not expected to occur on the site is provided in Attachment 3.

California brown pelican is found primarily within 12 miles of shore, but regularly up to 100 miles away from the coast. Pelicans are common along the coast throughout the year. The area extent of the foraging range of the brown pelican off the California coast is greatest in the Southern California Bight. This wide distribution is likely tied to the presence of several offshore islands that provide roosts and subsea topography that enhances thermal upwelling, which both support healthy populations of prey items. California brown pelican is found in estuarine, marine, subtidal, and marine pelagic waters. It requires water, rocky cliffs, jetties, sandy beaches, or mudflats for roosting, and open water for foraging. Although these birds were not observed at or within 500 feet of the project site during the site visit, conditions on-site may be favorable for foraging pelicans. There are no potential roost areas for pelicans in the vicinity of the site.
Mammals
Two nonlisted pinniped species protected by the MMPA, California sea lion ( Eumetopias jubatus) and harbor seal (Phoca vitulinasea), were determined to have a high or moderate potential to occur on the project site. These two species are discussed below. Information about mammal species that were determined to have a low potential to occur or very low potential to occur, or are not expected to occur on the site is provided in Attachment 3.
California sea lion is a year-round resident of the Southern California Bight. In this area, California sea lion breeds in large colonies, or rookeries, on San Miguel and San Nicolas Islands, with smaller breeding colonies on Santa Barbara and San Clemente Islands.
Breeding occurs from May through August. California sea lions are gregarious and are often observed in small groups swimming, porpoising, surfing waves, or resting on shore. They tend to prefer haul-out sites that have limited human access, and the appearance of a person can frighten the group into the water. Sea lions seem to be habituated to constant or low-frequency sounds, but they have been known to be alarmed by sudden loud noises (Dailey et al. 1993). The nearest known California sea lion haul-out location is 29 miles to the southwest at Bird Rock off the coast of Santa Catalina Island (NOAA NMFS 2013).
Harbor seal is the most common pinniped in the world, occurring in the Atlantic and Pacific Oceans. Pacific harbor seal ranges from Herschel Island, Alaska, to Baja California. Eastern Pacific harbor seal (Phoca vitulina richardsi) is a subspecies that occurs within the Southern California Bight. Breeding season in California is from March through June, with peak pupping in April and May. Harbor seals maintain haul-out sites on both mainland and island coasts that have unrestricted access to the water. They are sensitive to human disturbance but will reoccupy a site once they no longer feel threatened (Dailey et al. 1993). The nearest known eastern Pacific harbor seal haul-out location is 29 miles to the southwest at Eagle Rock off the western tip of Santa Catalina Island (NOAA NMFS 2013).

These species were not observed on-site during surveys. However, sea lions and seals were infrequently observed in the vicinity of the Termino Avenue Drain Replacement Project outfall construction site and subsequent eelgrass transplant beds. Further, these species are often observed in the vicinity of the Alamitos Bay Marina. While these species may initially be wary of construction noise, they can become habituated to the activity and may approach the project site. However, no haul-out habitat is present on-site for either species.
Plants
A CNDDB search of the project site and a 5-mile radius resulted in 10 sensitive plant species known to occur in the general project area. Of these species, only the estuary seablite has any potential to occur on-site. Information about plant species that were not expected to occur on the site is provided in Attachment 3.
Estuary seablite was not observed on-site and was determined to have a low potential to occur on the project site. The leaves of estuary seablite are pale to green, densely crowded and overlapping, and up to 3.5 centimeters (approximately 1.5 inches) in length. Plants flower from May through October, but predominantly in the late summer (Ferren 1993). The survey was conducted early in the flowering period; however, due to the highly developed state of the project site, the presence of a native species such as estuary seablite would have likely stood out against the ornamental landscape, even without flowers. This species occurs in coastal salt marshes, swamps, and tidal flats, and is found in clay, silt, and sand substrates just above the mean higher high water level. On the project site, highly disturbed sand substrates just above mean higher high water level are present. However, recreation and maintenance activities in this area make it unlikely that this plant has established on- site.
Conclusions
Open water on-site may periodically support pinnipeds protected by the MMPA. While highly unlikely, it is also possible that a transient green turtle may enter Alamitos Bay and approach the project site. California brown pelican may forage in the open water areas adjacent to the project site, and other birds may nest in the vicinity.
Biological monitoring and other relevant avoidance measures may need to be implemented during construction for nesting birds and marine mammals. Any proposed in-water work will likely need to be reviewed by the National Marine Fisheries Service (NMFS), as the intertidal areas where eelgrass was observed are considered EFH. Standard construction best management practices and monitoring during construction would likely be sufficient avoidance measures. Following construction, implementation of eelgrass bed restoration at the site would improve habitat conditions for marine species inhabiting the bay, outweighing any temporary disturbance associated with construction.

PROJECT MEMORANDUM
ALAMITOS BAY PUMP STATION DISCHARGE PIPE SUPPORTS REPLACEMENT PROJECT
Date: April 9, 2018
To: Ebigalle Voigt, Senior Civil Engineering Assistant, LA County DPW From: Stanley Yeh, Project Manager
Subject: Biological Resources Update
Purpose and Intent of the Memorandum
The County of Los Angeles Department of Public Works (LACDPW) has retained Aspen Environmental Group (Aspen) to update the existing Biological Inventory Survey (BIS) for the Alamitos Bay Pump Station Discharge Pipe Supports Project ( project). The original biological inventory survey was prepared by AECOM in 2015 and was based on field work that was conducted on July 16, 2015 (AECOM, 2015). This memorandum summarizes the results of an updated background literature review and site visits conducted on September 18, 2017 and January 30, 2018.
Project Description
The LACDPW proposes to implement the project, which would remove existing discharge structure (including all timber piles and beams, temporary support crib wall elements, walkway assembly, lifeguard observation cabin, three reinforced concrete pipe lines and existing utility conduits attached to the structure), in Alamitos Bay (Photo 1). Following the removal of the existing discharge structure LACDPW would construct a replacement discharge line by inst alling new buried discharge pipes and a concrete outlet structure supported on driven piles. To construct the project, a cofferdam consisting of steel push- in piles would be installed around the entire perimeter of the construction area and the work area would be dewatered to facilitate installation of the buried pipes and construct the outlet structure.
The project also consists of removing the existing pump station roof and installing a new steel frame roof, 3 feet higher than existing to accommodate a n ew bridge crane. Additional improvement to the pump station includes replacing existing office, bathroom and their associated amenities, and all pump station access doors. Electrical service disconnection and reconnection, and pump station lighting upgrade would be performed.
The project site, as evaluated in the 2015 BIS included the temporary work area around the discharge structure, the pump station, and an ingress/egress route to the west (see Figure 1). Additional potential temporary impact areas have been identified by LACDPW and include an excavated material stockpile area, a temporary boat storage area, and a new ingress/egress route (see Figure 1).
Ingress/Egress Area: This additional work area includes a 6,408 -sq. ft. open space that is currently used as a boat storage facility by the City of Long Beach (Photo 2). It is situated between the LACDPW pump station and the Long Beach Sailing Center.
Construction Area, Temporary boat storage area: This additional work area includes a 4500-sq. ft. open space that is proposed to be used to temporarily house the City of Long Beach boats that are currently stored in the “Ingress/Egress Area”. It is currently used as a public sandy beach. During the 2018 survey it was being used as temporary construction area for the Leeway Sailing Peer and Dock Replacement Project (Photo 3).

2 Construction Area, Excavated Material Stockpile Area: This additional work area includes a 20,000-sq. ft. open space that would be used to stockpile the sediment that would be excavated from the work area (Photo 4).
Methods
Aspen Senior Biologist , Justin Wood visited the project site on September 18, 2017 to conduct a reconnaissance-level biological survey to evaluate the condition of the project site as compared with conditions described in the 2015 biological inventory survey. An additional reconnaissance -level survey was conducted by Wood on January 30, 2018 to survey the new potential temporary impact areas (excavated material stockpile area, a temporary boat storage area, an d a new ingress/egress route ).
Wood walked throughout the project site to look for plants and animals and to evaluate the habitat suitability for special -status species. During the September survey, Wood snorkeled in the project footprint area to determine the extent for the eel grass ( Zostera marina) beds and to look for aquatic organisms. All plant, fish, and wildlife species observed during the surveys were recorded in field notes.
Any species that had not been reported by AECOM (2015) are included in Attachment 1. Representative site photos are included in Attachment 2. An updated California Natural Diversity Database ( CNDDB) search was conducted to identify special-status species known from the USGS quads within 5-miles of the project site (Attachment 3). Additional resources such as the California Native Plant Society’s (CNPS) Inventory of Rare and Endangered Vascular Plants of California, Consortium of California Herbaria (CCH), inaturalist.org and ebird.org were also reviewed (CNPS, 2018; CCH, 2018; inatur alist.org, 2018; and ebird.org, 2018).
Vegetation and land cover on the original project site were included in the BIS (AECOM, 2015). Vegetation and land cover in the additional work areas were mapped by Aspen and described below (see Figure 1).
Vegetation Communities and Other Land Cover Types
Vegetation and land cover within the original project site is described in th is BIS. The following three temporary impact areas were surveyed in 2018 and are described below.
Ingress/Egress Area: This additional work area is entirely developed (see Figure 1 and Photo 2 ). It is unvegetated and regularly maintained.
Construction Area, Temporary Boat Storage Area: This additional work area i ncludes approximately 2,060-sq. ft. of open water and approximately 2,440 -sq. ft. of beach (see Figure 1 and Photo 3 ). These cover types match the descriptions in the BIS.
Construction Area, Excavated Material Stockpile Area: This additional work area is entirely beach that is unvegetated and regularly maintained as described in the BIS (see Figure 1 and Photo 4).
Special-status Biological Resources
Special-status Habitat
Habitat types covered by the Magnuson –Stevens Fishery Conservation and Management Act (MFCMA) are identified below.
Marine Habitat – Eelgrass Beds. As described in the BIS, approximately 0.005 acres (224 sq. ft.) of eelgrass habitat was mapped in the project footprint in 2015, with an additional 0.06 acre (2,584 sq . ft.) also

ALAMITOS BAY PUMP STATION DISCHARGE PIPE SUPPORTS REPLACEMENT PROJECT
3 mapped within 50 feet of the project footprint. During the reconnaissance -level survey in 2017 Wood confirmed that the extent of the eelgrass habitat was accurate and remained unchanged (Photo 5) .
Alamitos Bay is considered Essential Fish Habitat (EFH) under the MFCMA. The BIS adequately described the EFH and eelgrass beds within the project site.
Special-status Species
Special-status species considered in this report include species listed or proposed for listing as endangered or threatened under the federal Endangered Species Act (ESA) or the state ESA. It also includes animals recognized by the California Department of Fish and Wildlife (CDFW) as species of special concern, plants ranked by the California Native Plant Society as 1A, 1B, 2, and 4, and species covered under the Migratory Bird Treaty Act (MBTA) or the Marine Mammal Protection Act (MMPA). A CNDDB search of the project site and all USGS quads within 5-miles of the site resulted in 52 special-status plant and animal species occurring in the general project area (Attachment 4) Of these, 21 were not previously addressed and have therefore been evaluated in the Attachment 3.
Invertebrates. The following three special-status invertebrates were identified in the CNDDB search and were not addressed in the BIS. These species are listed in Attachment 3 and are not likely to be present on the project site or to be impacts by project activities. • Crotch bumble bee (Bombus crotchii)
• wandering skipper (Panoquina errans)
• Dorothy’s El Segundo Dune weevil (Trigonoscuta dorothea dorothea)
Reptiles. No additional special-status reptiles were identified in the CNDDB search. Additional information regarding green sea turtle (Chelonia mydas) is provided here . The green sea turtle is a federally listed threatened species (USFWS and NOAA, 2016). It was addressed in the BIS , which stated, “the nearest know aggregation is approximately 100 miles south in San Diego Bay.” Green sea turtles are known from the San Gabriel River, between the Interstate 405 and the Pacific Ocean, including portions of Anaheim and Alamitos Bays (CDFW, 2018). Most of the observations have been concentrated near a warm water discharge coming from the Los Angeles Department of Water and Power’s Haynes Generating Station.
However, the sea turtles routinely disperse from the immediate discharge location for foraging in the surrounding area. The CNDDB shows a mapped polygon in the eastern portion of Alamitos Bay, within approximately 0.65 miles of the project site (CDFW, 2018). Green sea turtles have a moderate potential to be present occasionally in Alamitos Bay, in and near the project site.
Birds. The following five additional special-status birds were identified in the CNDDB search and were not addressed in the BIS (Attachment 3).
• ferruginous hawk (Buteo regalis)
• western yellow-billed cuckoo (Coccyzus americanus occidentalis) • coastal California gnatcatcher (Polioptila californica californica) • black skimmer (Rynchops niger)
• least Bell’s vireo (Vireo bellii pusillus)
Of these additional special-status bird species, black skimmer (Rynchops niger) is the only one that has a potential to be present. Black skimmer is a CDFW species of special concern (CDFW, 2018). Black skimmers are common along the California coast and can be found year-round. They are commonly seen on open sandy beaches and in coastal saltmarshes in the region. They are aerial feeders that forage on small fish that are captured in flight. They nest on beaches, gravel bars, or on islands in marshes. Black skimmers

4 were not observed at the project site during the surveys but have been reported approximately twelve times within 0.5-miles of the project site (ebird.org, 2018) and are likely to be present at least seasonally in or adjacent to the project site. Nesting is not expected within the project site because of the high use of the area by humans and pets and regular maintenance to the sandy beach.
Most nesting birds are protected by the federal Migratory Bird Treaty Act (MBTA) and California Fish and Game Code. No nesting native birds were observed during Aspen’s field visits. However, during the 2018 survey, rock pigeon (Columba livia) nests were observed on a wood beam supporting the lifeguard observation tower (Photo 6). Rock pigeons are a non-native species designated as feral wildfowl and are therefore not protected by the MBTA or California Fish and Game Code. If other native bird species nest in or adjacent to the project site these species would be protected.
It should also be noted that during the survey in 2017, brown pelicans were observed within about 100 feet of the project site, consistent with the BIS which identified a high potential for occurrence.
Mammals. The following th ree special-status mammals were identified in the CNDDB search and were not addressed in the BIS. These species are listed in Attachment 3 and are not likely to be present on the project site or to be impacts by project activities. Non-listed pinniped species protected by the MMPA are adequately addressed in the BIS.
• western mastiff bat (Eumops perotis californicus)
• western yellow bat (Lasiurus xanthinus)
• pacific pocket mouse (Perognathus longimembris pacificus)
Plants. The following ten special-status plant species were identified in the CNDDB search and were not addressed in the BIS. These species are listed in Attachment 3 and are not likely to be present on the project site or to be impacts by project activities.
• Ventura Marsh milk-vetch (Astragalus pycnostachyus var. lanosissiums) • Coulter’s saltbush (Atriplex coulteri)
• Parish’s brittlescale (Atriplex parishii)
• lucky morning-glory Calystegia felix
• Los Angeles sunflower (Helianthus nuttallii ssp. parishii) • decumbent goldenbush (Isocoma menziesii var. decumbens) • Gambel’s water cress (Nasturtium gambelii)
• prostrate vernal pool navarretia (Navarretia prostrata) • Lyon’s pentachaeta (Pentachaeta lyonii)
• Brand’s star phacelia (Phacelia stellaris)
Conclusions
All potential impacts to special -status biological resources can be mitigated through preconstruction surveys, monitoring, and avoidance measures. One federally listed species, green sea turtle, has some potential to be present in or adjacent to the project site . California brown pelican and black skimmers, both CDFW speci es of special concern were either observed or expected to occur in the open w ater habitat immediately adjacent to the project site. These species are not expected to nest on the project site. Aspen recommends addressing any potential indirect impacts (i.e. foraging) in the CEQA document, and identifying avoidance measures to be imp lemented during project construction. In addition, the project would need to be reviewed by the National Marine Fisheries Service (NMFS), which is the federal

5 agency responsible for regulation of the green sea turtle, MMPA, and the intertidal areas where eelgrass was observed. We recommend that t he CEQA document provide avoidance measures as needed to reduce or avoid impacts to these biological resources.

Conservation Status
Federal designations (Fed): (federal ESA, USFWS).
END: Federally listed, endangered.
THR: Federally listed, threatened.
Candidate: Sufficient data are available to support federal listing, but not yet listed.
Proposed: Formally proposed for the federal status shown.
State designations (CA): (CESA, CDFW)
END: State listed, endangered.
THR: State listed, threatened.
RARE: State listed as rare (applied only to certain plants).
CSC: California Species of Special Concern. Considered vulnerable to extinction due to declining numbers, limited geographic ranges, or ongoing threats.
WL: Species that were either previously listed as SC and have not been state listed under CESA; or were previously state or federally listed and now are on neither list; or are on the list of “Fully Protected” species.
FP: Fully protected. May not be taken or possessed without permit from CDFG.
SA: Special animal. Tracked by the CNDDB as species of conservation concern.
CDFW Natural Diversity Data Base Designations: Applied to special-status plants and sensitive plant communities; where correct category is uncertain, CDFG uses two categories or question marks.
S1: Fewer than 6 occurrences or fewer than 1000 individuals or less than 2000 acres.
S1.1: Very threatened
S1.2: Threatened
S1.3: No current threats known
S2: 6-20 occurrences or 1000-3000 individuals or 2000-10,000 acres (decimal suffixes same as above).
S3: 21-100 occurrences or 3000-10,000 individuals or 10,000-50,000 acres (decimal suffixes same as above).
S4: Apparently secure in California; this rank is clearly lower than S3 but factors exist to cause some concern, i.e., there is some threat or somewhat narrow habitat. No threat rank.
S5: Demonstrably secure or ineradicable in California. No threat rank.
SH: All California occurrences historical (i.e., no records in > 20 years).
SX: Presumed extirpated in California.
California Rare Plant Rank designations. Note: According to the California Native Plant Society (http://www.cnps.org/cnps/rareplants/ranking.php), plants ranked as CRPR 1A, 1B, and 2 meet definitions as threatened or endangered and are eligible for state listing. That interpretation of the state Endangered Species Act is not in general use. 1A: Plants presumed extinct in California.
1B: Plants rare and endangered in California and throughout their range. 2A: Plants presumed extinct in California but more common elsewhere in their range. 2B: Plants rare, threatened or endangered in California but more common elsewhere in their range. 3: Plants about which we need more information; a review list. 4: Plants of limited distribution; a watch list.
California Rare Plant Rank Threat designation extensions:
.1 Seriously endangered in California (over 80% of occurrences threatened / high degree and immediacy of threat)
BIOLOGICAL RESOURCES UPDATE
ALAMITOS BAY PUMP STATION DISCHARGE PIPE SUPPORTS REPLACEMENT PROJECT 15 .2 Fairly endangered in California (20-80% occurrences threatened) .3 Not very endangered in California (<20% of occurrences threatened or no current threats known) Definitions of occurrence probability: Estimated occurrence probabilities are based on literature sources cited earlier, field surveys, and habitat analyses reported here.
Present: Observed on the site by qualified biologists.
High: Habitat is a type often utilized by the species and the site is within the known range of the species.
Moderate: Site is within the known range of the species and habitat on the site is a type occasionally used.
Low: Site is within the species’ known range but habitat is rarely used, or the species was not found during focused surveys covering less than 100% of potential habitat or completed in marginal seasons.
Minimal: No suitable habitat on the site; or well outside the species’ known elevational or geographic ranges; or a focused study covering 100% of all suitable habitat, completed during the appropriate season and during a year of appropriate rainfall, did not detect the species.

Re: AB52 Consultation request for Alamitos Bay Pump Station Discharge Pipe Supports Project located 400 feet east of the intersection of 54th place and Ocean Blvd in the City of Long Beach
Dear John T. Walker,
Please find this letter as a written request for consultation regarding the above-mentioned project pursuant to Public Resources Code § 21080.3.1, subd. (d). Your project lies within our ancestral tribal territory, meaning belonging to or inherited from, which is a higher degree of kinship than traditional or cultural affiliation. Your project is located within a sensitive area and may cause a substantial adverse change in the significance of our tribal cultural resources. Most often, a records search for our tribal cultural resources will result in a “no records found” for the project area. The Native American Heritage Commission (NAHC), ethnographers, historians, and professional archaeologists can only provide limited information that has been previously documented about California Native Tribes. This is the reason the NAHC will always refer the lead agency to the respective Native American Tribe of the area because the NAHC is only aware of general information and are not the experts on each California Tribe. Our Elder Committee & tribal historians are the experts for our Tribe and are able to provide a more complete history (both written and oral) regarding the location of historic villages, trade routes, cemeteries and sacred/religious sites in the project area. Therefore, to avoid adverse effects to our tribal cultural resources, we would like to consult with you and your staff to provide you with a more complete understanding of the prehistoric use(s) of the project area and the potential risks for causing a substantial adverse change to the significance of our tribal cultural resources.
Consultation appointments are available on Wednesdays and Thursdays at our offices at 910 N. Citrus Ave. Covina, CA 91722 or over the phone. Please call toll free 1-844-390-0787 or email [email protected] to schedule an appointment.
** Prior to the first consultation with our Tribe, we ask all those individuals participating in the consultation to view a video produced and provided by CalEPA and the NAHC for sensitivity and understanding of AB52. You can view their videos at: http://calepa.ca.gov/Tribal/Training/ or http://nahc.ca.gov/2015/12/ab-52-tribal-training/ With Respect,
Andrew Salas, Chairman

Response to Comment B – Zach Rehm, California Coastal Commission
B-1 The ground elevations nearer the street appear to be only about one foot higher than at the existing site. Moving the structure to that location would provide only marginal additional protection from flooding, but would not remove the structure from the floodplain, which extends to the other side of the street. The major project improvements are to the discharge structure which is not subject to flood damage. The upgrades to the building and electrical equipment are minor and since this is an existing building with similar equipment already in place, it would not be considered a new impact requiring mitigation. Per CEQA Section 15126.6(a), an EIR is required to evaluate “Alternative to the Proposed Project.” However, per CEQA Section 15070-15075 and 15126.6, an IS/MND is not required to evaluate alternatives.
B-2 The pump station is an existing structure and its main purpose is to alleviate flooding in the Belmont Shore area. The major project improvements are to the discharge structure which is not subject to flood damage. The upgrades to the building and electrical equipment are minor and since this is an existing building with similar equipment already in place, it would not be considered a new impact requiring mitigation in the event of flooding or sea level rise.
Therefore, the project would not exacerbate existing or future flood hazards in the project area, resulting in a sub-structural risk of loss, injury, or death.
The analysis of sea level rise, whether how a project could affect sea level rise or how a project could be affected by sea level rise, is not required under CEQA. Effective December 28, 2018, the California Office of Planning and Research updated the CEQA Guidelines, including Appendix G (Environmental Checklist Form). Please note, neither the previous nor the updated CEQA Guidelines require an analysis of sea level rise. Therefore, this topic does not warrant a response under CEQA. However, the County revised the MND to include sea level rise analysis in Section IX (Hydrology and Water Quality), on page 61 of the Initial Study, as follows:
The project is within FEMA Flood Zone AE, meaning it is within the 100-year floodplain. The estimated 100-year flood elevation is 9 feet above mean sea level (MSL) (FEMA, 2008). Ground elevations at the site are approximately 6 feet, meaning the site could be flooded up to three feet in depth during a 100-year flood. The site is also within the area identified by the California Emergency Management Agency as subject to the effects of tsunami (California Emergency Management Agency, 2009). Sea level rise could add additional flood depth. According to the 2018 Ocean Protection Council’s Sea Level Rise Guidance (CNRA, 2018), by the year 2100, the median sea level rise at this location would be 1.3 to 2.2 feet depending on greenhouse gas emissions, with a likely range of 0.7 to 3.2 feet. This likely rise in sea level would not be sufficient to put the adjacent ground at the pump station permanently under water but could add to the 100-year flood level depths approximately equivalent to the sea level rise. It would also have the effect of making the site inundation more frequent.

C-1 As discussed in Section 3.4.I (Aesthetics), on pages 15 -16 of the Initial Study Section, with implementation of the project, views of the site would no longer be dominated by aging infrastructure. Beneficial impacts to public viewsheds of the site would occur with project implementation and the project would not substantially degrade the existing visual character or quality of the site and its surroundings. The size of the structure has been designed to the absolute minimum to maintain the functionality of the pump station and flood control operation. The realignment of the discharge line to underground will significantly reduce the visual impact of the structure to the surrounding amenities and beach users. The pump station roof replacement has included aesthetic features such as utilizing metal siding and roof panels with color and type matching the surrounding structures owned by the City of Long Beach.
The exterior walls and new doors will be repainted and finished with color matching the surrounding buildings. This will create an overall uniform and harmonic appearance.
C-2 Public access to the beach facing the Pacific Ocean would not be affected during construction of the project. While a small area (approximately 200 feet by 100 feet) would be fenced temporarily during construction to provide an excavated material stockpile locati on (refer to Figure 2), public access would not be affected as beachgoers could easily walk around this area. Construction is expected to only last approximately four months. Once completed, the project would have no impact to public access to the beach facing the Pacific Ocean.
For safety purposes, during construction, beach access facing Alamitos Bay would be temporarily prohibited inside the project area (refer to Figure 2 in the Initial Study).
Construction is expected to only last approximately four months. The affected portion of the beach facing Alamitos Bay is approximately 100 feet by 100 feet. To ensure the safety of the public adjacent to the construction zone and prevent any accidents or injuries, temporary chain link fence would be necessary around the construction zone to prevent trespassing.
Pedestrian detour plans will be implemented during the construction period to facilitate pedestrian traffic and connect the Bayshore area and Gondola Getaway kayak rentals. This will allow public access to these uses while also protecting the public from the construction zone.
Construction would occur within Alamitos Bay, resulting in a temporary closure area extending from approximately 70 feet within the Bay (at high tide) to Ocean Boulevard . The work area extends beyond the low tide line, therefore, tidal changes would not affect the temporary closure area. Hence , a project setback from the high tide line would not apply because the project extends into Alamitos Bay. Public access to the beach east of the project area would remain open and accessible from Ocean Boulevard. Public access to the beach west of the project area would remain open and accessible from 54th Place. Therefore, public access to the beach facing Alamitos Bay was not found to be impacted. Once constructed, maintenance of the new facility would occur similar or identical to that of existing conditions at the beach facing Alamitos Bay and would not impede public access.
C-3 CEQA specifically provides that parking impacts of a project are not considered significant impacts on the environment (California Public Resources Code Section 21099). Thus, they are exempt from CEQA review and not included within CEQA Guidelines or Appendix G (2018 Alamitos Bay Pump Station, Discharge Line Replacement Project Appendix F: Response to Comments
F-8
CEQA Environmental Checklist Form: http:// resources.ca.gov/ceqa/docs/ab52/final- approved-appendix-G.pdf). Therefore, this topic does not warrant response under CEQA.
Nevertheless, it is discussed below, as presented in Section 3.4.XVI ( Transportation and Traffic), on pages 82-83 of the Initial Study Section:
The project site has off-street parking for two vehicles. These off-street spaces would be used both during construction and operation. Operation & Maintenance parking would solely utilize these off -street spaces and would not utilize public s treet parking in the area. During construction, a staging area is proposed south of Ocean Boulevard that would be used for stockpiling and construction equipment storage. Construction personnel would utilize 15 street parking spaces on Ocean Boulevard, adj acent to the project site, that would be temporarily closed to the public during construction (refer to Figure 2). However, within 500- feet of the intersection of Ocean Boulevard and 54th Place (this area includes the public parking of Ocean Boulevard proposed for closure immediately adjacent to the project site), a review of GoogleEarth shows the following public parking spaces are available:
• Approximately 35 spaces along the north side of Ocean Boulevard, including over 20 diagonal spaces directly adjacent to the project site (the proposed project would temporarily close 15 of these parking spaces).
• Approximately 45 spaces along the north side of Ocean Boulevard, including over 25 diagonal spaces west of 54th Place.
• A public parking lot located at t he southwest corner of Ocean Boulevard and 54th Place with over 100 spaces available.
While Map 17 of the City of Long Beach Mobility Element shows this area to be parking impacted (meaning that there is limited off- street parking available), the loss of 15 public parking spaces adjacent to the project site during construction would be temporary. The total numbers of available public parking spaces near the project site, and the temporary loss of 15 parking spaces is considered to not impact the overall availability of public street parking in the area.
C-4 Potential impacts to water quality are discussed in Section 3.4.IX (Hydrology and Water Quality), on pages 60 -64 of the Initial Study. Potential impacts to water quality would be minimized by constructi ng during the dry season and using a cofferdam to temporarily separate the construction area from the bay. Although the construction area is less than one acre and compliance with the Construction General Permit is not required, the Department of Public Works proposes similar measures to prevent and minimize water contamination which are described in Section 2.5 (Project Design Features), pages 9 -10 of the Initial Study.
Compliance with Sections 404 and 401 of the Clean Water Act would also require development and implementation of measures intended to mitigate adverse water quality effects. The project would not change the capacity for higher volume flows and would not increase storm water discharges to the bay. Therefore, there would be no increase in floo d-related contaminants. Less than significant impacts to water quality would occur.

Appendix G. Mitigation Monitoring and Reporting Program As a condition of approval of the Alamitos Bay Pump Station, Discharge Line Replacement Project, adopted mitigation measures shall be implemented as specified below. The Mitigation Monitoring and Reporting Program (MMRP) is implemented as a requirement of CEQA (Guidelines Section 15097).
This MMRP will help ensure that project objectives are achieved. Los Angeles County Public Works (DPW) shall be responsible for administering the MMRP and ensuring that all parties comply with its provisions. The DPW may delegate monitoring activities to staff, consultants, or contractors. The D PW also will ensure that monitoring is documented through periodic reports and that deficiencies are promptly corrected. The DPW, or its designated environmental monitor, will track and document compliance with mitigation measures, note any problems that may result, and take appropriate action to rectify problems.

BIO-1 Pre-construction Special -status Species Surveys. Prior to the start of any project activities a qualified project biologist would be assigned and would survey the project site and a 100 -foot buffer around the site for special -status species. The project biologist would be familiar with all special-status species that have a potential to be present, including green sea turtle, protected pinnipeds, and native birds. If federally or state listed species are detected during these surveys, they shall be avoided, and the US Fish and Wildlife Service and California Department of Fish and Wildlife notified within 24 hours, as appropriate. If any non- listed special -status species are detected, they would be avoided with the implementation of avoidance buffers to be determined by the biologist.
Prior to the start of the project, all construction personnel would be informed on the potential for sea turtles to be present in the project site. Construction personnel would be instructed to avoid direct contact with these species and avoid harassment in any way. Also prior to any project work in the bay, a pre -
construction fish and turtle survey would be completed. The project biologist would direct a team of fisheries biologists, who would use seine nets to clear the work limits. The net would be installed at low tide, starting from the beach and working into the bay to exclude any fish and turtles. No turtles would be handled or forced to leave the area but instead would be passively relocated from the work area using the nets. Any additional aquatic organisms that are encountered in the work area would be relocated from the project site as feasible. Once the work area has been cleared the seine net would be installed around the perimeter of the work area to exclude these species from re-entering the area. The seine net would be kept in place until the cofferdam has been installed.

BIO-2 Green Sea Turtle Avoidance. If the seine nets (as required in BIO-1), are damaged or accidentally moved, the project biologist shall be on site during any construction activities occurring in or over the water to monitor the presence of green turtles. The project biologist shall have the authority to temporarily halt construction operation s and shall determine when construction operations can resume.
Even with the seine net or coffer dam in place, construction activity within or over the water shall be temporarily stopped if a green sea turtle is observed within 100 feet of the work site. W ork would only resume when the turtle safely leaves the area. Construction personnel shall be briefed on potential for green sea turtle to be present and would be provided with its identification characteristics, since it may occasionally be mistaken for a seal or sea lion.
The construction manager would inform the project biologist of the sea turtle observation, and the biologist shall prepare an incident report of any green sea turtle activity in the project area.
The report shall be provided within 24 hours to California Department of Fish and Wildlife and the National Marine Fisheries Service.

BIO-4 Nesting Bird Avoidance. Structure demolition and initial ground disturbance would be completed between September 16 and February 14 to avoid the nesting bird season. If these activities must take place during the nesting season, a nesting bird survey would be completed by the project biologist no earlier than three days prior to the start of these activities. The survey would be conducted throughout the project site and within approximately 100 feet of the project site. If an active nest is found, a buffer around the nest would be established in which no work would be allowed until nesting is complete (i.e., until juvenile birds leave the nest or until the nest fails and is abandoned by the adult birds). The size of the nest buffer would be determined by the project biologist, based on the species sensitivity and specific nest site conditions. Limits of avoidance shall be demarcated with flagging or fencing. Once a nest is determined to be no longer active, the project biologist would remove all flagging and allow construction activities to proceed.

CR-1 Management of Unanticipated Historical Resources or Unique Archaeological Resources. If unrecorded archaeological resources (e.g., midden, unusual amounts of shell, animal bone, bottle glass, ceramics, structure/building remains) are encountered during construction activity, all ground-disturbing activities will be restricted within a 100- foot radius of the find or a distance determined by a qualified professional archaeologist to be appropriate based on the potential for disturbance of additional cultural resource materials. A qualified archaeologist will identify the materials, determine their potential to meet the state CEQA Guidelines Section 15064.5 definition of a significant cultural resource, and formulate appropriate measures for their treatment. Poten- tial treatment methods for significant and potentially significant resources may include, but would not be limited to, no action (i.e., resources determined not to be significant); avoidance of the resource through changes in construction methods or project design; or implementation of a program of testing and data recovery, in accordance with applicable state requirements and/or in consultation with affiliated Native American tribes.

CR-2 Management of Unanticipated Human Remains. In accordance with the California Health and Safety and Public Resources Codes (PRC), if human remains are uncovered during ground- disturbing activities, the contractor and/or the County of Los Angeles, Department of Public Works will immediately halt potentially damaging excavation in the area of the burial and notify the county coroner and a professional archaeologist to determine the nature of the remains. The coroner is required to examine all discoveries of hu man remains within 48 hours of receiving notice of a discovery on private or state lands (California Health and Safety Code, Section 7050.5[b]). If the coroner determines that the remains are those of a Native American, he or she must contact the Native Am
erican Heritage Commission (NAHC) by phone within 24 hours of making that determination (Health and Safety Code, Section 7050[c]). Following the coroner’s findings, the property owner, the contractor or project proponent, an archaeologist, and the NAHC-designated Most Likely Descendant (MLD) will determine the ultimate treatment and disposition of the remains and take appropriate steps to ensure that additional human interments are not disturbed. The responsibilities for acting upon notification of a discov ery of Native American human remains are identified in PRC Section 5097.9.
Upon the discovery of Native American remains, the County will ensure that the immediate vicinity (according to generally accepted cultural or archaeological standards and practices) is not damaged or disturbed by further development activity until consultation with the MLD has taken place. The MLD will have 48 hours after being granted access to the site to complete a site inspection and make recommendations. A range of possible tre atments for the remains may be discussed, including nondestructive removal and analysis, preservation in place, relinquishment of the remains and associated items to the descendants, or other culturally appropriate treat - ment. PRC Section 5097.9 suggests t hat the concerned parties may extend discussions beyond the initial 48 hours to allow for the discovery of additional remains.
The County will employ the following site protection measures:
(1) record the site with the NAHC or the appropriate Information Center, (2) use an open-space or conservation zoning designation or easement, and (3) record a document with the county in which the property is located.
If the NAHC is unable to identify a MLD or the MLD fails to make a recommendation within 48 hours afte r being granted access to the site, the County or its authorized representative will rebury the Native American human remains and associated grave goods with appropriate dignity on the property in a location not subject to further subsurface disturbance. T he County or its authorized representative may also reinter the remains in a location not subject to further disturbance if it rejects the recommendation of the MLD and mediation by the NAHC fails to provide measures acceptable to the County.

Paleo-1 Monitoring for Paleontological Resources. The County of Los Angeles, Department of Public Works (County) shall secure the services of a project paleontologist. The project paleontologist shall have knowledge of local paleontology and the minimum level of experience and expertise as defined by the Society of Vertebrate Paleontology’s Standard Procedures for the Assessment and Mitiga - tion of Adverse Impacts to Paleontological Resources. The project paleontologist shall supervise a paleontological resources monitor who meets Society of Vertebrate Paleontology (2010) quali - fications who shall be available on an on -call basis for all ground disturbing activities within soils at or below a depth of five feet below ground surface. When a monitor is needed, the monitor will fill out daily monitoring forms. The project paleontologist will prepare a summary monitoring report. Monitoring will in clude the testing of sediment samples for microvertebrate fossils. The project paleontologist will seek authorization from the County to increase or decrease the monitoring effort should the monitoring results indicate that a change is warranted. In the ev ent that unanticipated discoveries are made, Mitigation Measure PALEO -2 will be implemented. At the end of monitoring and sediment sample processing, the project paleontologist will identify the significant fossils, if any, recovered, and prepare a summar y monitoring report. Monitoring will include the testing of sediment samples for microvertebrate fossils, and specifically collecting and processing a 15-gallon sample of sediments from the lowest level of the excavation. Once the 15-gallon sample is taken and processed and no paleontological resources have been seen in the monitoring, the paleontological monitoring may cease.
