Ste 305 Phoenix, AZ 85016 Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California Dear Mr. Schwarz: This letter report provides an analysis of potential biological resource impacts associated with the proposed warehouse/distribution building project (project) located in the City of Chula Vista, California (Assessor’s Parcel Number 644-040-01-00). This biology letter report also includes a discussion of any potential biological resources that may be subject to regulation under the City of Chula Vista Multiple Species Conservation Program (MSCP) Subarea Plan (Subarea Plan) (City of Chula Vista 2003). 1 Project Location The study area is approximately 9.72 acres and is located approximately 0.2 miles east of the Interstate 805 (I- 805)freeway between Main Street and Olympic Parkway (Figure 1). The site is located on Shinohara Lane accessed from Brandywine Avenue and is located on the U.S. Geological Service 7.5-minute series topographic Imperial Beach quadrangle map. The site exists within an urban portion of the City and is bound on the south and east by industrial buildings, to the west by single-family residences, and to the north by multifamily condominiums (Figure 1). 2 Project Description The proposed project plans to develop one parcel, consisting of approximately 9.72 vacant acres at 571 Shinohara Lane, generally located north of Main Street, at the terminus of Shinohara Lane and easterly Brandywine Avenue (behind the Curbell Plastics building) in the City of Chula Vista. The site is planned for one parcel and a 173,432 square foot warehouse/distribution building, including a 4,506 square foot office. The maximum proposed building height is 43 feet. Access to the project will be provided via a driveway at the terminus of Shinohara Lane. Due to the topography of the site, retaining walls are expected. The site is General Plan designated IL – Limited Industrial and Zoned ILP – Limited Industrial P. Photos of the site are included in Appendix A. 3 Survey Methods Dudek conducted the original vegetation mapping and assessed the site for potential jurisdictional features on January 18, 2018 and visited the site again on July 23, 2021 to check the previous mapping. The survey area APPENDIX D Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 2 November 2022 consists of the vacant parcel and existing roads leading into the site (Figure 1). The vegetation communities and land covers were mapped according to Holland (1986) and Oberbauer (2008). An aerial photograph map (Google Earth 2018) with a digital overlay of the project boundary was utilized to record vegetation and any sensitive biological resources directly in the field. All plant species and animal species encountered during the survey were identified and recorded. In addition to species actually detected during the surveys, expected wildlife use of the site was evaluated by known habitat preferences of local species and knowledge of their relative distributions in the area. A compiled list of the plant and animal species detected on site during this survey is attached to this letter report as Appendix B and Appendix C, respectively. On January 18, 2018, Dudek conducted a burrowing owl (Athene cunicularia) habitat assessment following the protocol in the Staff Report for Burrowing Owl Mitigation (CDFG 2012), with the exception of the survey buffer. A 150- meter buffer was not surveyed due to the existing residential and commercial development. A total of approximately 2.5 hours were spent on site from 8:00 a.m. to 10:30 a.m. and temperatures ranged from 57° Fahrenheit (F) to 61°F; conditions were clear with little to no wind (0 to –3 mph). The entire site was surveyed on foot by conducting a series of east–west transects to provide 100% cover and look for burrowing owls, their sign, or presence of suitable burrows (>11 centimeters in diameter and >150 centimeters in depth). Transects were walked at a pace that allowed careful observations along the transect route and immediate vicinity. Photographs were taken to record conditions of the site. Potential burrow locations were recorded using GPS, photographed, and documented. A focused burrowing owl survey was conducted in the non-breeding season on January 25, 2018, following the survey guidelines in the Staff Report for Burrowing Owl Mitigation (CDFG 2012). The site was surveyed from 7:00 a.m. 9:30 a.m. and the temperature ranged from 53°F to 55°F with very light wind (1 to 5 mph). Cloud cover varied between 60% to 70% throughout entire survey. Line transects were walked on foot to ensure 100% visual coverage of the site; lines were spaced between 7 meters to 20 meters apart and adjusted for vegetation height and density. At the start of each transect line, the surrounding area was scanned using binoculars. Special attention was given to areas identified as having potential active burrows determined from the initial burrowing owl habitat assessment. Dudek botanist Erin Bergman conducted a rare plant survey on June 1, 2022 by walking transects throughout the entire study area. The study area was surveyed between 8:24 a.m. and 1:49 p.m. with temperatures ranging from 67°F to 74°F with very light wind (0–3 mph) and 0% to 10% cloud cover. 4 Survey Results Existing conditions observed on site suggest that the property has been graded and disturbed. The southern portion of the site is mostly flat, while much of the northern portion is sloped and heavily eroded. There is a small cement drainage ditch that begins near the center of the site and extends approximately 160 meters southeast to the project boundary. In addition, there are two other cement drainage ditches: one runs parallel to the eastern border and the other runs parallel to the southern border of the site. The July 23, 2021 survey resulted in changes to the original 2018 mapping. Burrowing owl is known to occur in the area (Unitt 2004); California Natural Diversity Database records are primarily located near Otay Mesa approximately 3 miles east of the project site (CDFW 2022); however, no burrowing owls were observed during the 2018 or 2021 site visits or the focused burrowing owl survey on January 25, 2018. Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 3 November 2022 4.1 Flora The site supports a very limited amount of native vegetation, most of which is indicative of highly disturbed areas. The site does not provide good quality habitat for native plant species, and is dominated (i.e., 70%) by non-native perennial and weedy annual species. A total of 64 plants were identified on site (Appendix A). The most common non-native plants identified include Russian thistle (Salsola tragus), brome grasses (Bromus spp.), and oat grasses (Avena spp.). The common native plants are limited to the disturbed Diegan coastal sage scrub and include California buckwheat (Eriogonum fasciculatum) and California sagebrush (Artemisia californica). According to the recognized San Diego County vegetation mapping systems (i.e., Holland 1986 and Oberbauer 2008) the site is classified as disturbed Diegan coastal sage scrub, non-native grassland, eucalyptus woodland, disturbed habitat, and urban/developed (Figure 2). The acreages of the vegetation communities and land covers are listed in Table 1. On-site vegetation and land cover mapping is defined and described below. Table 1. Vegetation Communities and Land Cover within the Study Area Habitat Type Tier Acreage Mitigation Ratios1 Required Mitigation (Ac.) Disturbed Diegan coastal sage scrub II 0.54 1:1 0.54 Eucalyptus woodland IV 0.10 N/A 0 Non-native grassland III 7.04 0.5:1 3.52 Disturbed habitat IV 2.04 N/A 0 Urban/Developed IV 0.02 N/A 0 Total -- 9.72 -- 4.06 1 The mitigation ratios range is based on the location of the mitigation inside the preserve. Disturbed Coastal Sage Scrub: Inland Form (dCSS) is a habitat type that consists of low-growing, woody shrubs that are most active in winter and early spring; they are drought-hardy and adapted to low moisture. This vegetation community typically occurs below 1,000 feet. These areas are dominated by California sagebrush, California buckwheat, as well as laurel sumac (Malosma laurina), all three of which were identified on site. On site, the percentage of native vegetation on site is less than 40%; the remainder of the vegetation within this area is non-native herbs or small shrubs (e.g., Russian thistle) and is therefore mapped as “disturbed” Diegan coastal sage scrub. Non-Native Grassland (NNG) is a vegetation community with dense to sparse cover of annual grasses, typically comprised of Avena, Bromus, Erodium, and/or Brassica species (Oberbauer 2008). On site, the non-native grassland areas are dominated by slender oat (Avena barbata), wild oat (Avena fatua), purple false brome (Brachypodium distachyon), ripgut brome (Bromus diandrus), soft brome (Bromus hordeaceus), and red brome (Bromus rubens). Some areas mapped as non-native grassland show evidence of tilling or disturbance, but grasses are still intact and dominant on the landscape. Disturbed Habitat (DH) is a land cover type that is characterized by a predominance of non-native species, often introduced and established through human action. Disturbed habitat has been physically disturbed, and is no longer recognizable as native or naturalized vegetation, while retaining a soil substrate (Holland 1986 and Oberbauer 2008). The site consists of two types of substrate: Olivenhain cobbly loam and Salinas clay loam (USDA 2018). The City’s Subarea Plan identifies disturbed habitat as disturbed lands and is considered Tier IV “other uplands” (City Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 4 November 2022 of Chula Vista 2003). These areas are dominated by prickly Russian thistle and slender oat. Tier IV uplands are not considered sensitive under the City’s Subarea Plan (City of Chula Vista 2003). Urban/Developed (DEV) is land that is currently developed or on which construction is currently underway. Whether the structures are permanent, semi-permanent, pavement, hardscape, or irrigated landscape, the land no longer has the ability to support native vegetation due to the extent of its physical modifications (Holland 1986 and Oberbauer 2008). Ornamental landscapes such as the row of non-native pine trees along the eastern perimeter of the site are identified as urban/developed land. 4.2 Fauna Due to the predominance of non-native vegetation and site disturbance characteristics, the site has limited potential to provide habitat that support wildlife species. The project site is mostly surrounded by existing development and has no connectivity to habitat areas that would be considered “open space preserve lands” in the City’s Subarea Plan. Furthermore, given the residential surroundings, the site is unlikely to serve as a wildlife corridor. Several non-native trees exist along the perimeter of the project site; however, they are small, and it is unlikely that special-status birds (including special-status raptors) would use the site for nesting. There are no prominent rocks, boulders, or features on site that could be used by special-status reptiles. The few wildlife species detected during the survey are listed in Appendix C of this letter report. A total of 22 wildlife species were observed and identified during the survey. Commonly observed species include white-crowned sparrow (Zonotrichia leucophrys), Anna’s hummingbird (Calypte anna), mourning dove (Zenaida macroura), lesser goldfinch (Spinus psaltria), killdeer (Charadrius vociferus), and common side-blotched lizard (Uta stansburiana); one red-tailed hawk (Buteo jamaicensis) was seen soaring above the project site. 4.3 Special-Status Species 4.3.1 Special-Status Plants Tarplants are a group of annual species that have the potential to thrive in areas of disturbance. A summer special- status plant survey pass was completed on June 1, 2022 specifically focused on tarplant species and other late season rare plants. A rare plant reference check was performed for Otay tarplant (Deinandra conjugens) on May 31, 2022 within 4 miles of the site. Otay tarplant was observed in full bloom at the offsite reference check location. In addition, the reference check location also consisted of populations of San Diego ragweed (Ambrosia pumila) a rhizomatous perennial rare plant typically observed year-round. Flowers were also present on this perennial herb. Reference check site photos and videos are saved to Instagram account socalrare_plants (Instagram 2022). After conducting late season rare plant surveys, no special-status species have moderate or high potential to occur onsite due to the sites disturbed nature (including soil disturbance) and consistent mowing and maintenance practices. See Appendix D for potential to occur summaries. 4.3.2 Special-Status Wildlife Burrowing owl. No burrowing owls were observed during the 2018 or 2021 site visits or the focused burrowing owl survey on January 25, 2018. Although there is potential for burrowing owl to occur, no burrowing owl, occupied Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 5 November 2022 sites or burrows, or evidence of recent burrowing owl sign (pellets, scat, feathers, tracks, etc.) were observed on the property during the site visits. Two potential burrowing owl burrows were detected in the northern portion of the site in 2018 (Figure 2); however, these were not observed during the 2021 site visit and one of the areas has been significantly disturbed. Potential California ground squirrel (Otospermophilus [Spermophilus] beecheyi) and other rodent burrows were also observed on portions of the site; however, no sign of burrowing owl use was detected at these burrows or elsewhere of the site. The site supports marginal habitat for burrowing owls based on the results of the habitat assessment. Monarch. Monarch (Danaus plexippus plexippus) is a butterfly species known from western and eastern North America and is a candidate for federal listing as threatened or endangered. Monarchs depend on milkweed (Asclepias spp.) as their host plants for egg laying and overwinter in large groves of roost trees with very specific microclimates characterized high humidity, freshwater, and the lack of freezing temperatures or high winds. No host plants are present on the project site and the mapped eucalyptus woodland on the project site is comprised of only a few trees not suitable as Monarch overwintering habitat. Therefore, the site does not contain habitat suitable to support monarchs. Quino checkerspot butterfly. Quino checkerspot butterfly (Euphydryas editha quino) is a covered species under the City’s Subarea Plan. Per Section 5.2.8.2 in the City’s Subarea Plan, “Outside of the Preserve, protocol surveys for quino checkerspot butterfly presence will be required for Development Areas only within Non-Preserve Habitat- Category A east of SR125”. The Proposed Project is located west of SR125 and therefore does not require focused surveys. In addition, this small parcel is surrounded by development on all sides lacking the ability for quino checkerspot butterfly to access the site. The site has no quino checkerspot butterfly host plants and lacks nectar plant species. Few flowering species are present onsite and are limited where they occur. In addition, the majority of flowering species are non-native. Finally, the soils onsite are highly disturbed therefore cryptogamic crusts are not present which can be associated with quino checkerspot butterfly. 4.4 Jurisdictional Wetland Resources No jurisdictional wetland resources are present on site. There are several concrete drainage channels within the interior and along the perimeter of the site used for on-site drainage. These were constructed wholly in uplands (HistoricAerials.com 2022) to support on-site drainage that do not connect to any waters of the State or U.S. 4.5 Wildlife Corridors and Habitat Linkages Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the immigration and emigration of animals. Wildlife corridors contribute to population viability through the following: 1. Ensuring the continual exchange of genes between populations, which helps maintain genetic diversity 2. Providing access to adjacent habitat areas, representing additional territory for foraging and mating 3. Allowing for a greater carrying capacity 4. Providing routes for colonization of habitat lands following local population extinctions or habitat recovery from ecological catastrophes (e.g., fires) Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 6 November 2022 Habitat linkages are patches of native habitat that function to join two larger patches of habitat. They serve as connections between habitat patches and help reduce the adverse effects of habitat fragmentation. Although individual animals may not move through a habitat linkage, the linkage does represent a potential route for gene flow and long-term dispersal. Habitat linkages may serve as both habitat and avenues of gene flow for small animals such as reptiles and amphibians. Habitat linkages may be represented by continuous patches of habitat or by nearby habitat “islands” that function as “stepping stones” for dispersal. The MSCP defines core and linkage areas as those maintaining ecosystem function and processes, including large animal movement. Each core area is connected to other core areas or to habitat areas outside of the MSCP either through common boundaries or through habitat linkages. Core areas have multiple connections to help ensure that the balance in the ecosystem will be maintained. The project site is not located within a biological core area or biological linkage (see Figure 1-4 of the Subarea Plan (City of Chula Vista 2003)). The Otay River Valley provides a major wildlife corridor for the entire South Bay region (Figure 3). The Otay River is located approximately 0.25 mile from the project site and is separated entirely by residential and commercial development and Main Street. The project site is not expected to provide for wildlife movement or serve as a habitat linkage since it not connected to, or located near, other habitat areas. The project is located within a currently undeveloped parcel that is surrounded by existing, high-density commercial and residential development. Because of regular human activity and considerable vehicle traffic in and surrounding the project site, predominantly urban-adapted wildlife species are expected to occur in this area, such as raccoons (Procyon lotor), Virginia opossum (Didelphis virginiana), striped skunk (Mephitis mephitis), and brush rabbits (Sylvilagus spp.). 5 Regulatory Context The municipalities of southwestern San Diego County collaborated in producing the MSCP Subregional Plan (County of San Diego 1998). The MSCP Subregional Plan is implemented through individual Subarea Plans adopted by each jurisdiction in order to receive “take authorization” for impacts to covered species and habitats. The MSCP serves as a Habitat Conservation Plan pursuant to Section 10(a)(1)(B) of the federal Endangered Species Act of 1973, as well as a Natural Communities Conservation Plan under the Natural Community Conservation Planning Act of 2001. The MSCP, as implemented through the Subarea Plans, allows the participating jurisdictions to authorize take of plant and wildlife species identified within the plan area. The U.S. Fish and Wildlife Service (USFWS) and California Department of Fish and Wildlife (CDFW) have authority to regulate the take of threatened, endangered, and rare species. Under the MSCP, the USFWS and CDFW have granted take authorization to the local jurisdictions, including the City, for otherwise lawful actions, such as public and private development, that may incidentally take or harm individual species or their habitat outside of the designated Preserve areas, in exchange for the assembly and management of a coordinated MSCP Preserve. The City of Chula Vista is a participant in the San Diego MSCP through the Chula Vista Subarea Plan. The MSCP is implemented in Chula Vista through the City’s approved MSCP Subarea Plan (City of Chula Vista 2003). Within the City’s Subarea Plan, the project site is designated as “Development Area Outside of Covered Projects” (i.e., not designated a preserve or conservation area) (Figure 3). The closest preserve is the Otay River, approximately 0.2 miles to the south and is separated from the project site by Main Street and industrial buildings. Therefore, the site is not adjacent to the preserve and is not subject to land use adjacency guidelines. Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 7 November 2022 As defined by the Subarea Plan, projects within the Development Area outside of Covered Projects planning area shall adhere to the City’s Habitat Loss and Incidental Take (HLIT) Ordinance. Consistency with regional resource planning is discussed further below. 5.1 Habitat Loss Incidental Take Ordinance For projects within Development Areas Outside of Covered Projects that contain sensitive biological resources and for which the project site is greater than 1 acre, the HLIT Ordinance requires a biological evaluation of the resources on site. In compliance with the MSCP Subregional Plan and the Subarea Plan, the City established development standards in the HLIT Ordinance, as a condition of issuance of take authorization by the USFWS and CDFW. The HLIT is consistent with the conservation and mitigation goals of the 1998 MSCP Subregional Plan and the City’s Subarea Plan. Furthermore, the HLIT provides standards for development, identifies specific impact thresholds, and defines the mitigation requirements for impacts to native and some non-native communities (e.g., non-native grassland). Impacts to Tier I, II, and III habitats will be mitigated pursuant to HLIT mitigation standards provided in Table 5-3 of the Subarea Plan. Based on the current site conditions, there is 0.54 acre of disturbed Diegan coastal sage scrub and 7.04 acres of non-native grassland that could be impacted by the project. These would require 4.06 acres of mitigation. The HLIT provides protection of Narrow Endemic Species and wetland impact avoidance/minimization; however, due to the continued disturbance to the site over the years, no Narrow Endemic Species are expected to occur on site, and there are no potential wetlands on site. Table 2, Table 3, and Table 4 summarize the project’s conformity to the Required Findings, General MSCP Development Regulations, and Specific MSCP Land Use and Development Regulations for the HLIT Ordinance. Table 2 Required Findings for Issuance of an HLIT Permit (Chula Vista Municipal Code 17.35.080) Required Findings for Issuance of an HLIT Permit (Section 17.35.080): Analysis Consistency The proposed development in the Project Area and associated mitigation are consistent with the Chula Vista MSCP Subarea Plan as adopted on May 13, 2003, and as may be amended from time to time, the MSCP Implementation Guidelines, and the development standards set forth in Section 17.35.100 of the Municipal Code. Section 5.2.2 HLIT Ordinance of the Subarea Plan (City of Chula Vista 2003) requires issuance of an HLIT permit for “all development within the City’s jurisdiction which is not located within the Development Areas of Covered Projects prior to issuance of any land development permit.” As such, the entire Project site would require issuance of an HLIT permit. The Project would impact sensitive biological resources within disturbed coastal sage scrub and non-native grassland. Mitigation for these impacts will be in accordance with the ratios in the Subarea Plan. Mitigation measures have been incorporated into the project to Consistent Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 8 November 2022 Table 2 Required Findings for Issuance of an HLIT Permit (Chula Vista Municipal Code 17.35.080) Required Findings for Issuance of an HLIT Permit (Section 17.35.080): Analysis Consistency compensate for direct and indirect impacts to sensitive vegetation communities. Mitigation for impacts to these habitat types are described in Mitigation Measure MM-BIO-1. Other Mitigation Measures that apply include migratory and nesting bird measures. Mitigation for these impacts will be in accordance with the City of Chula Vista MSCP Subarea Plan (HLIT). Prior to issuance of any land development permits, the applicant shall mitigate for direct impacts pursuant to Section 5.2.2 of the City’s MSCP Subarea Plan (City of Chula Vista 2003). In compliance with the City’s Subarea Plan, the applicant shall secure mitigation credits within San Miguel Conservation Bank consistent with the ratios specified in Table 1 which are in accordance with the ratios set forth in the Subarea Plan. The nature and extent of mitigation required as a condition of the permit is reasonably related to and calculated to alleviate negative impacts created in the Project Area. Appropriate mitigation measures, consistent with the MSCP, have been proposed and will be implemented for this project and are provided within the Biology Letter Report. Consistent Narrow Endemic Findings There are no narrow endemic species on site. Consistent Wetland Findings There are no wetlands on site. Consistent Prior to the issuance of a Land Development Permit or Clearing and Grubbing Permit, the project proponent will be required to obtain any applicable state and federal permits, with copies provided to the Director of Planning and Building or his/her designee. There are no biological resources on site that require state or federal permits. Consistent Impacts to wetlands have been avoided and/or minimized to the maximum extent practicable, consistent with the City of Chula Vista MSCP Subarea Plan Section 5.2.4. There are no wetlands on site.

There are no wetlands on site. Consistent Table 3 General MSCP Development Regulations (CVMC 17.35.090) General MSCP Development Requirements (Section 17.35.090) Analysis Consistency Overall development within the Project Area including public facilities and circulation shall be located to minimize impacts to Sensitive Biological Resources in accordance with this chapter of the Chula Vista MSCP Subarea Plan and the MSCP Implementation Guidelines. The project site is located in an otherwise developed area, surrounded by residential and commercial development. Additionally, the site has been repeatedly disturbed. The site has very minimal biological value and does not contribute to adjacent preserves or undeveloped areas. Consistent Pursuant to Chapter 15.04 of the Chula Vista Municipal Code, no Land Development or Clearing and Grubbing Permit that allows clearing, grubbing, or grading of Natural Vegetation shall be issued on any portion of a Project Area where impacts are proposed to Wetlands or Listed Non-covered Species until all applicable federal and state permits have been issued. There are no biological resources on site that require state or federal permits. Consistent Impacts to Wetlands shall be avoided to the maximum extent practicable. Where impacts to Wetlands are not avoided, impacts shall be minimized and mitigated pursuant to Section 17.35.110 of the Municipal Code. There are no wetlands on site. Consistent No temporary disturbance or storage of material or equipment is permitted in Sensitive Biological Resources unless the disturbance or storage occurs within an area approved by the City for development or unless it can be demonstrated that the disturbance or storage will not cause permanent habitat loss and the land will be revegetated and restored in accordance with the MSCP Implementation Guidelines. The project does not propose any temporary disturbance or storage of material or equipment in Sensitive Biological Resource Areas. Consistent Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 10 November 2022 Table 3 General MSCP Development Regulations (CVMC 17.35.090) General MSCP Development Requirements (Section 17.35.090) Analysis Consistency Grading during wildlife breeding seasons shall be avoided or modified consistent with the requirements of the Chula Vista MSCP Subarea Plan and in accordance with the MSCP Implementation Guidelines. To avoid any direct impacts associated with construction activities, Mitigation Measure MM-BIO-3 is proposed to encourage construction outside of the breeding season (February 1 through September 15). If construction does occur during the breeding season, specific actions would be taken to avoid impacts consistent with the requirements of the Chula Vista MSCP Subarea Plan and in accordance with the MSCP Implementation Guidelines. Consistent All fuel modification brush management zones required as a result of new development and as required by the City Fire Marshal shall be located outside the Preserve. There are no preserve areas on site or adjacent to the site. Consistent Table 4 Specific MSCP Land Use and Development Regulations (CVMC 17.35.100) Specific MSCP Land Use and Development Requirements (Section 17.35.100) Analysis Consistency Land uses and development are permitted within the 100 percent conservation areas consistent with the Chula Vista MSCP subarea plan and Section 17.35.100 (A). There are no preserve/conservation areas on site. N/A Land uses and development are permitted within the 75 to 100 percent conservation areas consistent with the Chula Vista MSCP subarea plan and Section 17.35.100 (B). There are no preserve/conservation areas on site. N/A Land uses and development are permitted within development areas outside of covered projects consistent with the Chula Vista MSCP subarea plan and Section 17.35.100 (C). See below. Consistent Permitted land uses include those uses permitted in the underlying zone. The project would be consistent with existing zoning. Consistent Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 11 November 2022 Table 4 Specific MSCP Land Use and Development Regulations (CVMC 17.35.100) Specific MSCP Land Use and Development Requirements (Section 17.35.100) Analysis Consistency Encroachment into natural vegetation is not limited except as may be provided by CVMC 17.35.090(A)(2) and/or (A)(3). The Project would impact sensitive biological resources within disturbed coastal sage scrub and non-native grassland. Mitigation for these impacts will be in accordance with the ratios in the Subarea Plan. Mitigation measures have been incorporated into the project to compensate for direct and indirect impacts to sensitive vegetation communities. Mitigation for impacts to these habitat types are described in Mitigation Measure MM-BIO-1. Consistent Development shall avoid impacts to covered narrow endemic species to the maximum extent practicable. A list of the covered narrow endemic species is included in the Chula Vista MSCP subarea plan and the MSCP implementation guidelines. Measures for protection of narrow endemic species shall be required such as management, enhancement, restoration and/or transplantation in accordance with the MSCP implementation guidelines. There are no narrow endemic species on site. Consistent 6 Project Impacts This section addresses direct impacts and indirect impacts that will result from implementation of the project. Direct Impacts may include both the permanent loss of on-site habitat and the plant and wildlife species that it contains. The current site design assumes impacting the entire project site. Indirect Impacts refer to off-site and on-site effects that are short-term impacts (i.e., temporary) due to the Project construction or long-term (i.e., permanent) design of the project and the effects it may have to adjacent resources. For this project, it is assumed that the potential indirect impacts resulting from construction activities may include dust, noise, general human presence that may temporarily disrupt species and habitat vitality, and construction- related soil erosion and runoff. No long-term indirect impacts are assumed to occur as the project site is surrounded by urban development such that implementation of the project would not have a long-term effect on adjacent wildlife or suitable habitat. Therefore, long term indirect impacts would be considered less than significant. Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 12 November 2022 Direct Impacts Vegetation Communities and Land Cover Types The proposed project would impact the entire site. The acreages and mitigation requirements are summarized in Table 1, above. Urban/developed lands and disturbed habitat provide little native habitat value and foraging opportunities for wildlife and impacts to these vegetation communities/land covers would not be considered significant. No mitigation is required for impacts to eucalyptus woodland, disturbed habitat or urban/developed lands, in accordance with the requirements in the HLIT ordinance. Direct impacts to 0.54 acres of disturbed Diegan coastal sage scrub and 7.04 acres of non-native grassland would be considered significant and mitigation would be required, according to the requirements and ratios in the HLIT ordinance and Table 5-3 of the MSCP (Table 1). Impacts would be reduced to less than significant through implementation of MM-BIO-1. Waters of the U.S., including Wetlands No jurisdictional resources were identified within the project impact area, therefore there are no direct impacts to waters of the U.S., including wetlands. Special-Status Plants No special-status plants were detected in the project study area during the 2018, 2021, or 2022 surveys. Additionally, focused rare plant surveys were conducted for rare late season blooming species with no special- status plant species detected on the project site. There are no special-status plant species with a moderate or high potential to occur within the project study area and, due to the extent of vegetative disturbance and lack of suitable substrate, special-status plant species are not expected to occur (Appendix D). Therefore, no significant direct impacts to special-status plants are anticipated. Special-Status Wildlife Monarch butterfly was observed nectaring on site during the July 2021 site visit. While there are flowering plants, the site lacks this species’ host plant (Asclepias spp.) and suitable overwintering habitat and impacts to this special-status species would be less than significant. While burrowing owl has low potential to occur and was not detected during site surveys including the focused burrowing owl survey, if this species were to occur on site prior to project activities, impacts to an active nest would be considered significant, absent mitigation. Impacts would be reduced to less than significant through implementation of MM-BIO-2. No other special-status wildlife species were detected during the 2018 or 2021 surveys, and the potential for special-status species to occur in the study area is low due to the disturbed nature of the site (past grading, presence of invasive species, etc.) and the location being surrounded by urban development (Appendix E). Based on this information, no additional significant direct impacts to special-status wildlife species are anticipated. All raptors species and their nests are protected under the California Fish and Game Code, and raptor species may use the site for foraging. Stands of small ornamental trees are present within the project study area and a Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 13 November 2022 one red-tailed hawk was seen soaring over the site; however, no nests were observed. Although raptor species have the potential to occur in the study area, lands within the impact footprint are primarily disturbed. The ornamental trees on site are small, and it is unlikely that raptors would use the site for nesting. Although raptors are unlikely to nest on the project site, the potential impact to nesting raptors would be avoided through implementation of MM-BIO-3. Wildlife Corridors and Habitat Linkages There are no wildlife corridors or habitat linkages on site; therefore, there are no direct impacts to wildlife corridors or habitat linkages. Indirect Impacts Vegetation Communities and Land Covers The entire site would be impacted so no short-term indirect impacts would occur to on-site vegetation communities. Short-term indirect impacts that may affect the small amount of undeveloped areas adjacent to the project site include dust, invasive plant species, and increased human presence. Typical construction BMPs will limit the spread of dust. Increased human presence is a potential short-term indirect impact. During construction, typical BMPs, such as having trash containers on site, a demarcated limit of work, and contractor education, will limit the potential for trash and other human disturbance. The project plans will incorporate methods to control runoff, including a Storm Water Pollution Prevention Plan (SWPPP) to meet National Pollution Discharge Elimination System (NPDES) regulations. Therefore, short-term indirect impacts to off site, adjacent vegetation communities are not considered significant. The only potential long-term indirect impact is the change in storm water discharge hydrology downstream of the project. It is assumed that the project will be designed in accordance with NPDES regulations and as such, the project is not expected to result in any long-term indirect adverse impacts. Waters of the U.S., including Wetlands No jurisdictional resources were identified within the project impact area, therefore no indirect impacts to waters of the U.S., including wetlands, would occur. Special-Status Plant Species Following completion of the vegetation mapping in 2018 and site visit in 2021, there are no special-status plant species with moderate to high potential to occur adjacent to the study area, and therefore, indirect impacts to off- site special-status plant species are not expected to occur. Special-Status Wildlife Species Most of the indirect impacts to vegetation communities previously described can also affect special-status wildlife. Wildlife may also be indirectly affected in the short-term by construction-related noise, which can disrupt normal activities and subject wildlife to higher predation risks. Adverse edge effects can cause degradation of habitat Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 14 November 2022 quality through the invasion of pest species. Nesting birds can be significantly affected by short-term construction- related noise, which can result in the disruption of foraging, nesting, and reproductive activities. The project vicinity supports suitable vegetation for bird nesting, including trees associated with the street and property landscaping, and vegetated areas mapped onsite. The property and surrounding areas have the potential to support nesting habitat for common raptors (e.g., red-tailed hawk) and songbirds protected by the Migratory Bird Treaty Act. Indirect impacts from construction-related noise may occur to breeding wildlife if construction occurs during the breeding season (i.e., February 1 through September 15). Wildlife that would be significantly affected by noise, based on suitable habitat in the project vicinity. Species whose breeding/nesting may be significantly impacted by noise include common raptor species. This impact would be considered a significant impact, absent mitigation. Impacts would be reduced to less than significant through implementation of MM-BIO-3. Wildlife Corridors and Habitat Linkages There are no wildlife corridors or habitat linkages on site and the site is entirely surrounded by development; therefore, there are no indirect impacts to wildlife corridors or habitat linkages. 7 Mitigation Implementation of the measures below would reduce the impacts to less than significant. MM-BIO-1: Compensatory Uplands Mitigation: Per the HLIT ordinance, 7.58 acres of impacts to sensitive uplands shall be mitigated at the required mitigation ratios (Table 1). To compensate for the loss of 0.54 acre of disturbed coastal sage scrub (Tier II) and 7.04 acres of non-native grassland (Tier III), mitigation would be provided through compensatory upland mitigation. Compensatory Uplands Mitigation. Prior to the issuance of any grading permit, including clearing, grubbing, grading and construction permits, the project applicant shall mitigate direct impacts to 0.54 acre of coastal sage scrub habitat pursuant to the City of Chula Vista Multiple Species Conservation Program (MSCP) Subarea Plan (Subarea Plan) and Habitat Loss Incidental Take (HLIT) Ordinance. Per the HLIT Ordinance, impacts to coastal sage scrub shall be mitigated at the ratios identified in the MSCP Subarea Plan Table 5-3. Considering the project site is located outside of the preserve, coastal sage scrub mitigation provided through the purchase of credits at the San Miguel Conservation Bank shall be at a 1:1 ratio. The project applicant shall mitigate direct impacts to 7.04 acre of non-native grassland habitat pursuant to the City of Chula Vista MSCP Subarea Plan and HLIT Ordinance. Per the HLIT Ordinance, impacts to non-native grassland shall be mitigated at the ratios identified in the MSCP Subarea Plan Table 5-3. Considering the project site is located outside of the preserve, non-native grassland mitigation through the purchase of credits at the San Miguel Conservation Bank shall be at a 0.5:1 ratio. The applicant shall secure mitigation credits within the San Miguel Conservation Bank. Mitigation credits shall be for habitat of equivalent or higher habitat value than coastal sage scrub for impacts to Mr. Steven Schwarz Subject: Biology Letter Report for Shinohara Business Center (previously 517 Shinohara Lane), City of Chula Vista, California 13619 15 November 2022 coastal sage scrub and equivalent or higher habitat value than non-native grasslands for non-native grassland impacts, with value determined consistent with the Subarea Plan tier system (see Subarea Plan Table 5-3). The applicant is required to provide the City with verification of mitigation credit purchase prior to issuance of any grading permit, including clearing, grubbing, grading and construction permit MM-BIO-2: Burrowing Owl Take Avoidance Surveys. Take avoidance surveys are intended to detect the presence of burrowing owls on a project site at a fixed period in time and inform necessary take avoidance actions. Take avoidance surveys may detect changes in owl presence such as colonizing owls that have recently moved onto the site, migrating owls, resident burrowing owls changing burrow use, or young of the year that are still present and have not dispersed (CDFG 2012). Prior to issuance of any land development permits, including clearing, grubbing, and grading permits, the Proposed Project applicant or its designee shall retain a qualified biologist to conduct take avoidance surveys for burrowing owl. The take avoidance survey(s) can be conducted between 14 days and 24 hours prior to initiating ground disturbance activities; however, time lapses between project activities may require subsequent surveys within 24 hours prior to ground disturbance. The development of avoidance and minimization approaches would be informed by monitoring the burrowing owls. MM-BIO-3: Avoidance of Nesting Bird Impacts: To avoid any direct impacts any species identified as a candidate, sensitive, or special status species in the HLIT, MSCP Subregional Plan, or other local or regional plans, policies or regulations, or by the CDFW or USFWS, removal of habitat that supports active nests in the proposed project study area should occur outside of the breeding season of these species (February 1 to September 15), where feasible. If removal of habitat must occur during the nesting season, a qualified biologist shall conduct a pre-construction survey to determine the presence or absence of nesting birds within the proposed area of disturbance. The pre-construction survey shall be conducted no more than 72 hours prior to the start of construction activities (including removal of vegetation). If more than 72 hours lapse between the original survey and construction activities that include vegetation removal on all or a portion of the site, a new survey(s) shall be conducted. If nesting birds are detected, a letter report or mitigation plan in conformance with the HLIT and applicable state and federal law (e.g., appropriate follow-up surveys, monitoring schedules, and construction barriers/buffers) shall be prepared and include proposed measures to be implemented to ensure that take of birds or eggs is avoided. The report or mitigation plan shall be submitted to the City for review and approval and implemented to the satisfaction of the City.
