Summary The City of Los Angeles (City) is proposing the construction of two new youth baseball fields in one of three locations being considered within Griffith Park. Each alternative would require the removal of trees protected by the City of Los Angeles Tree Preservation Ordinance and the City of Los Angeles Department of Recreation and Parks (RAP) Tree Preservation Policy. Alternative 1, Option A (Alternative 1A), would require the removal of 45 trees, including 15 protected trees. Alternative 1, Option B (Alternative 1B), would require the removal of 68 trees, including 13 protected trees, six of which would require mitigation. Alternative 2 would require the removal of 28 trees. All tree removals would require mitigation.

Introduction The City of Los Angeles (City) is proposing the construction of two new youth baseball fields in one of three locations being considered within Griffith Park. An Initial Study was completed by the City in January 2013. The Initial Study concluded that additional technical studies and preparation of a Draft Environmental Impact Report (DEIR) be initiated. These studies are being prepared with the City of Los Angeles Bureau of Engineering as the Lead Agency under the California Environmental Quality Act (CEQA). The purpose of this study is to analyze the potential for impacts of the proposed project with regard to biological resources.
Project Location The proposed project would be located in the Hollywood community of the city of Los Angeles and entirely within Griffith Park. The park is located northwest of downtown Los Angeles, just west of the Golden State Freeway (Interstate 5 [I‐5]), roughly between Los Feliz Boulevard on the south and the Ventura Freeway (State Route 134 [SR‐134]) on the north (see Figure 1).
As shown in Figure 2, three locations are being considered for the proposed project. Alternative 1, Option A (Alternative 1A), would be located at 4730 Crystal Springs Drive, within the northeastern part of the Crystal Springs Picnic Area of the park. The Alternative 1A site, which covers approximately 4 acres, is northeast of Pote Field, south of Harding Municipal Golf Course, and west of I‐5. Alternative 1, Option B (Alternative 1B), would also be located in the Crystal Springs Picnic Area but just southeast of Pote Field, on the grassy area across from the loop driveway and parking lot. Alternative 2 would be located in North Atwater Park, across from I‐5 and the Los Angeles River.
Project Description Alternatives Two alternatives are being considered as part of this technical study. Alternative 1 would locate the proposed baseball fields within the Crystal Springs Picnic Area of the park and include two options (Option A and Option B) for placement of the fields. Alternative 2 would locate the baseball fields just across from I‐5 and the Los Angeles River, within the North Atwater Park area of Griffith Park. The alternatives are described in more detail below.
Alternative 1, Option A – Crystal Springs North The City is proposing to construct two youth baseball fields within the north Crystal Springs Picnic Area of Griffith Park. Each baseball field would include a home plate, bases, a pitcher’s mound, batters’ and catchers’ boxes, two dugouts (with two benches, approximately 20 seats each), two bleachers, 16‐foot‐high outfield/perimeter fencing, natural grass, warm‐up areas, and a scoreboard (refer to Figure 3 for the conceptual project layout under Alternative 1A). Landscaping and an irrigation system would also be installed. In addition, Alternative 1A would involve upgrades to the existing restroom facility. Restroom upgrades would be limited to interior remodeling and measures to increase access for those with disabilities.

Under this alternative, seven picnic tables would be relocated within or near the Crystal Springs Picnic Area. The northeast segment of the loop driveway, which currently supports vehicle circulation around the Crystal Springs Picnic Area, would be removed to accommodate the baseball fields (see Figure 3). As a result, five parking spaces would be removed and two “hammerhead” turning circles would be created, replacing the existing access loop.
Alternative 1, Option B – Crystal Springs South The baseball fields proposed under Alternative 1B would include the same elements proposed under Alternative 1A. One baseball field would be located just southeast of Pote Field; the second would be located southeast of the first field, in the area across from the loop driveway and parking lot (see Figure 4). Alternative 1B would also involve upgrades to the existing restroom facility. Restroom upgrades would be limited to interior remodeling and measures to increase access for those with disabilities.
To accommodate this alternative, 56 picnic tables would be relocated within or near the Crystal Springs Picnic Area. No changes to existing circulation or parking are anticipated under this alternative.
Alternative 2 – North Atwater Park Under Alternative 2, an existing softball field would be retrofitted to accommodate youth baseball and a new youth baseball field would be constructed (see Figure 5). The existing backstop, bleachers, and player benches would remain; the rest of the softball field would be upgraded. The new youth baseball field would be constructed just north of the softball field. The new bleachers, backstop, and players’ benches would match those of the existing field.
To accommodate this alternative, an existing basketball and sand volleyball court would be removed. Unlike Alternatives 1A and 1B, Alternative 2 would not displace picnic tables, although new picnic tables would be added to the area as part of the project.
Construction Construction is anticipated to begin in the summer of 2015 and be completed in the summer of 2016 (approximately 12 months). Post‐construction activities (e.g., finalizing as‐built plans, training the maintenance and operations staff regarding the use of the scoreboard, irrigation systems, security lights, and other systems) would occur in the fall and winter of 2016–2017. The baseball fields would be fully operational in the spring of 2017.
Currently, it is anticipated that Pote Field and a portion of the Crystal Springs Picnic Area would remain open during construction of Alternative 1. Under Alternative 2, a portion of the North Atwater Park area would also remain open during construction.
The analysis in this document assumes that, unless otherwise stated, the project would be designed, constructed, and operated in compliance with all applicable laws, regulations, ordinances, and formally adopted City standards, including, but not limited to:

Additions and Amendments to the Standard Specifications for Public Works Construction
Regulatory Setting This section provides an overview of biological resources and evaluates impacts associated with the proposed project. Topics addressed would include existing vegetation, landscaping, biological resources, potential impacts on sensitive species (including migratory bird species), sensitive natural communities, and federally protected wetlands. This section was prepared utilizing information from a variety of sources, including the California Department of Fish and Wildlife’s (CDFW) California Natural Diversity Database (CNDDB), the California Native Plant Society’s (CNPS) Electronic Inventory, the U.S. Fish and Wildlife Service’s (USFWS) list of endangered and threatened species. The proposed project is evaluated in terms of whether the implementation of would result in the permanent loss of, or loss of access, to biological resources occurring within the project area.
Federal Federal Endangered Species Act. The Endangered Species Act and subsequent amendments provide for the conservation of endangered and threatened species and the ecosystems upon which they depend. Section 7 of the Endangered Species Act requires federal agencies to aid in the conservation of listed species; it also ensures that the activities of federal agencies will not jeopardize the continued existence of listed species or adversely modify designated critical habitat. At the federal level, the USFWS and the National Oceanic and Atmospheric Administration (NOAA) are responsible for administration of the Endangered Species Act (Endangered Species Act of 1973 (16 U.S.C. 1531‐1544, 87 Stat. 884).
Clean Water Act (CWA). At the federal level, the CWA (33 U.S.C. 1344) is the primary law regulating wetlands and waters. The CWA regulates the discharge of dredged or fill material into waters of the United States, including wetlands. Waters of the United States include navigable waters, interstate waters, territorial seas, and other waters that may be used in interstate or foreign commerce. To classify wetlands for the purposes of the CWA, a three‐parameter approach including the presence of hydrophytic (water‐loving) vegetation, wetland hydrology, and hydric soils (subject to saturation/inundation) is used. All three parameters must be present, under normal circumstances, for an area to be designated as a jurisdictional wetland under the CWA. Section 404 of the CWA establishes a regulatory program that provides that no discharge of dredged or fill material can be permitted if a practicable alternative exists that is less damaging to the aquatic environment or if the nation’s waters would be significantly degraded. The Section 404 permit program is run by the U.S. Army Corps of Engineers (ACOE) with oversight by the U.S. Environmental Protection Agency.
Executive Order for Wetland Protection. The Executive Order for the Protection of Wetlands (E.O. 11990) also regulates the activities of federal agencies with regard to wetlands. Essentially, this executive order states that a federal agency, such as the Federal Highway Administration,
Los Angeles Department of Public Works, Bureau of Engineering
Biological Resources Technical Study Griffith Park Crystal Springs New Baseball Fields Project 9 October 2013
ICF 00327.13
cannot undertake or provide assistance for new construction located in wetlands unless the head of the agency finds: 1) that there is no practicable alternative to the construction and 2) the proposed project includes all practicable measures to minimize harm.
Fish and Wildlife Coordination Act. The Fish and Wildlife Coordination Act (16 U.S.C. Sections 661‐ 667e, March 10, 1994, as amended 1946, 1958, 1978, and 1995) requires that whenever waters or a channel of a stream or other body of water are proposed or authorized to be modified by a public or private agency under a federal license or permit, the federal agency must first consult with the USFWS and/or NOAA Fisheries Service. This act requires compliance with the head of the agency exercising administration over the wildlife resources of the state where construction would occur (in this case the CDFW), with a view to conservation of birds, fish, mammals, and all other classes of wild animals and all types of aquatic and land vegetation upon which wildlife is dependent.
Migratory Bird Treaty Act (MBTA). The MBTA (16 U.S.C. Sections 703–711) includes provisions for the protection of migratory birds, including the non‐permitted take of migratory birds, under the authority of USFWS and CDFW. The MBTA protects over 800 species, including geese, ducks, shorebirds, raptors, songbirds, and many common species.
The MBTA decrees that all migratory birds and their parts (including eggs, nests, and feathers) are fully protected. Under the MBTA, taking, killing, or possessing migratory birds is unlawful. Projects that are likely to result in the taking of birds protected under the MBTA require the issuance of take permits from the USFWS. Activities that would require such a permit would include, but not be limited to, the destruction of migratory bird nesting habitat during the nesting season when eggs or young are likely to be present. Under this act, surveys are required to determine if nests will be disturbed and, if so, a buffer area with a specified radius around the nest would be established so that no disturbance or intrusion would be allowed until the young had fledged and left the nest. If not otherwise specified in the permit, the size of the buffer area would vary with species and local circumstances (e.g., presence of busy roads), and would be based on the professional judgment of the monitoring biologist.
State California Endangered Species Act. The CDFW is responsible for the administration of the California Endangered Species Act. Unlike the federal Endangered Species Act, there are no State agency consultation procedures under the California Endangered Species Act. For projects that affect both a State and federally listed species, compliance with the federal Endangered Species Act will satisfy the California Endangered Species Act if the CDFW determines that the federal incidental take authorization is "consistent" with the California Endangered Species Act. Projects that result in a take of a State‐only listed species require a take permit under the California Endangered Species Act. The federal and/or State acts also lend protection to species that are considered rare enough by the scientific community and trustee agencies to warrant special consideration, particularly with regard to protection of isolated populations, nesting or den locations, communal roosts, and other essential habitat.
California Fish and Game Code Sections 3500 through 3705, Migratory Bird Protection. Sections 3500 through 3705 of the California Fish and Game Code regulate the taking of migratory birds and their nests. These codes prohibit the taking of nesting birds, their nests, eggs, or any portion thereof during the nesting season. Typically, the breeding/nesting season is from March 1st
Los Angeles Department of Public Works, Bureau of Engineering
Biological Resources Technical Study Griffith Park Crystal Springs New Baseball Fields Project 10 October 2013
ICF 00327.13
through August 30th. Depending on each year’s seasonal factors, the breeding season can start earlier and/or end later.
State Agency Wetland Regulation. At the State level, wetlands and waters are regulated primarily by the CDFW and the Regional Water Quality Control Boards (RWQCBs). The RWQCBs were established under the Porter‐Cologne Water Quality Control Act to oversee water quality. The RWQCB also issues water quality certifications in compliance with Section 401 of CWA. In certain circumstances, the Coastal Commission or Bay Conservation and Development Commission may also be involved. Sections 1600‐1607 of the Fish and Game Code require any agency that proposes a project that will substantially divert or obstruct the natural flow of or substantially change the bed or bank of a river, stream, or lake to notify CDFW before beginning construction. If CDFW determines that the project may substantially and adversely affect fish or wildlife resources, a Lake or Streambed Alteration Agreement will be required. CDFW jurisdictional limits are usually defined by the tops of the stream or lake banks, or the outer edge of riparian vegetation, whichever is wider. Wetlands under jurisdiction of the ACOE may or may not be included in the area covered by a Streambed Alteration Agreement obtained from the CDFW.
Local County of Los Angeles Significant Ecological Area. The Los Angeles County Board of Supervisors designated Significant Ecological Areas (SEAs) in 1981 with the adoption of the General Plan. The collection of SEAs together was intended to designate critical components of the biodiversity of Los Angeles County as it was known and understood at that time (http://planning.lacounty.gov/view/sea‐existing). Most of Griffith Park is designated as SEA‐37; however, the project site is not located within an SEA.
City of Los Angeles General Plan (General Plan). The General Plan addresses community development goals and policies relative to the distribution of land use, both public and private, and acts to protect large tracts of open space for habitat conservation, species protection, watershed maintenance, and other purposes. The General Plan integrates the Citywide elements and community plans, and gives policy direction to the planning regulatory and implementation programs.
The General Plan Framework (Framework), adopted December 1996 and amended in August 2001, is a more general, long‐term, programmatic document, implemented by the various individual elements of the General Plan. Policies related to open space conservation and protecting the city’s natural resources, including biological resources such as sensitive species, habitats, and wildlife movement corridors, are found in the Framework. The state requires that conservation and open space elements be included in City and county general plans. The latter is to address conservation, protection, development, utilization, and reclamation of natural resources. The former is to address the remaining natural and other open space resources. Polices related to the protection and conservation of natural resources including biological resources are found in the Conservation Element of the City’s General Plan. The intent of the Conservation Element of the Framework is the conservation and preservation of natural resources, including (but not limited to) biological resources such as endangered species and habitats. The Conservation Element contains policies for avoidance and minimization of significant impacts to sensitive resources, protection, and conservation of habitats, and the establishment of habitat restoration and enhancement programs.

City of Los Angeles Tree Preservation Ordinance. Ordinance number 177404 is an ordinance amending various provisions of Articles 2 and 7 of Chapter I and Article 6 of Chapter IV and Section 96.303.5 of the Los Angeles Municipal Code to assure the protection of and to further regulate the removal of protected trees. This ordinance became law on April 23, 2006 (City of Los Angeles 2006). The ordinance regulates the following Southern California native tree species, measuring four inches or more in cumulative diameter, four and one‐half feet above the ground level at the base of the tree:
Any oak tree of the genus Quercus indigenous to California excluding Scrub Oak (Quercus dumosa)
Southern California Black Walnut (Juglans californica var. californica)
Western (California) Sycamore (Platanus racemosa), and
California Bay (Umbellularia californica).
All trees meeting the criteria above will be considered protected trees within this report. Removal or relocation of protected trees requires a permit from the Board of Public Works. Removal or relocation are defined as “any act that will cause a protected tree to die, including but not limited to acts that inflict damage upon the root system or other part of the tree by fire, application of toxic substances, operation of equipment or machinery, or by changing the natural grade of land by excavation or filling the drip line area around the trunk.”
A protected tree report (PTR) must be submitted to the Board of Public Works to apply for a tree removal permit. The PTR must contain the required information listed in the City of Los Angeles Standard Tree Removal Application Checklist, see Appendix A.
The City of Los Angeles Tree Preservation Ordinance requires mitigation for the removal of protected trees. The ordinance requires the replacement of each tree removed by at least four trees of the protected tree species of a 15 gallon or larger size specimen measuring one inch or more in diameter at a point one foot above the base and at least seven feet in height. The current Board of Public Works has increased the minimum requirements for protected tree replacement to 4:1 (see Appendix A). The exact size and number of trees planted for mitigation shall approximate the value of the tree to be replaced. The exact size and number of tree planted for mitigation will be determined by the City of Los Angeles. The ordinance also regulates the act of pruning of protected trees. Pruning must be approved and comply with the pruning standards set forth in the Western Chapter of the International Society of Arboriculture (ISA). A bond must be posted or other assurance acceptable to the city engineer to guarantee the survival of the trees required to be mitigated. A fee for the tree permit will be charged and will be determined in the manner provided in Section 12.37 I 1 of the Los Angeles Municipal Code for establishing fees.
City of Los Angeles Policies for the Installation and Preservation of Landscaping and Trees on Public Property. This policy was established in 1971 to establish measures for providing the maximum quantities of trees and other vegetation on public property to provide functional, ecological, aesthetic, and sociological public benefits. The policy requires all improvement projects to include a maximum number of trees and other vegetation, identifies who will be financially responsible for the improvements, and states who will prepare plans for the work and maintain the trees and vegetation. The policy identifies how removal of public trees and vegetation should be approached, including the investigation of alternatives to salvage trees before approval of removing existing trees. The replacement of trees and vegetation and the coordination of the policy program are identified therein (City of Los Angeles 1971).

City of Los Angeles Department of Recreation and Parks Griffith Park Wildlife Management Plan. The RAP established the Griffith Park Wildlife Management Plan (Plan) to document the park's biodiversity and provide recommendations to the City of Los Angeles for future management of its resources. The Plan establishes a baseline of biological resources documented within the park and identifies threats to these resources. Recommendations outlined in the Plan are intended to ensure that future park uses take into account the rich diversity of plant and wildlife species supported by Griffith Park and ensure that these resources are not negatively affected by the thousands of human visitors to the park each year.
City of Los Angeles Department of Recreation and Parks Tree Preservation Policy. The RAP established the Tree Preservation Policy as a regulatory tool to provide additional protections to urban forest trees within parks beyond the protections regulated by the City of Los Angeles Tree Preservation Ordinance (City of Los Angeles 2006). In addition to the trees protected by the Tree Preservation Ordinance, the Tree Preservation Policy regulates protection of Heritage, Special Habitat Value, and Common Park trees. The definitions of each are included below:
Heritage trees are individual trees of any size or species that are specifically designated as heritage because of their historical, commemorative, or horticultural significance. Heritage trees are protected trees. The Heritage Trees list can be obtained from RAP Griffith Maintenance/Forestry Division. Before a Heritage tree is pruned, damaged, relocated, or removed, recommendations from RAP staff arborists must be obtained. The Forestry Arborist makes a recommendation to the General Manager for removal. The General Manager or designee must make the final approval before the tree can be removed.
Special Habitat Value trees are protected trees and include Big Leaf Maple (Acer macrophyllum), Boxelder (Acer negundo), Toyon (Heteromeles arbutifolia), California Walnut (Juglans californica), Northern California Black Walnut (Juglans hindsii), California Sycamore (Platanus racemosa), Hollyleaf Cherry (Prunus ilicifolia), Catalina Cherry (Prunus lyonii), Fremont Cottonwood (Populus fremontii), Black Cottonwood (Populus trichocarpa), Sandbar Willow (Salix exigua), Red Willow (Salix laevigata), Pacific Willow (Salix lasiandra), Arroyo Willow (Salix lasiolepis), and California Bay (Umbellularia californica). Before a Special Habitat Value tree is pruned, damaged, relocated, or removed, recommendations from RAP staff arborists must be obtained. The Forestry Arborist makes a recommendation to the General Manager for removal. The General Manager or designee must make the final approval before the tree can be removed.
Common Park Trees provide aesthetic, sentimental, economical, and environmental value. Every tree in City of Los Angeles parks is recognized as a valuable asset and must be protected. The Forestry Arborist may recommend removal.
The RAP Tree Preservation Policy requires that Department of Recreation and Parks Arborists provide recommendations before any heritage, special habitat value, or common park tree can be removed, relocated, or pruned. Requests to remove, relocate, or prune protected trees must be submitted to the Forestry Division. Pruning must be in compliance with ISA tree pruning guidelines and under the supervision of an ISA certified staff member. For heritage and special habitat value trees, the Forestry Arborist makes a recommendation to the General Manager for removal. The General Manager or designee must make the final approval before the tree can be removed. For a Common Park Tree, the Forestry Arborist may recommend removal. For large scale tree removal projects, the Griffith Maintenance/Forestry Division must follow established Notification Protocol when informing the public, local government officials, organizations, and department representatives. Removal of trees under RAP’s tree preservation ordinance requires mitigation, including, replacement in accordance with the ordinance ratios. Coordination and authorization from RAP’s Urban Forestry Division is required.

Environmental Setting Griffith Park Overview Griffith Park, one the largest municipal parks in the nation, approximately 4,200 acres in size, was established in 1896 by the donation of private land owned by Colonel Griffith J. Griffith. The Park is owned and operated by the City and is located within the eastern edge of the Santa Monica Mountains at elevations ranging from approximately 384 to 1,625 feet above mean sea level (msl) and includes much rugged terrain consisting of rocky hills, canyons, and gullies. The project area is located within an area of gentle rolling hills at elevations ranging from approximately 408 to 420 feet above msl.
Griffith Park is located within the Hollywood Community Plan area of the city of Los Angeles and the Griffith Park Master Plan. The City of Los Angeles General Plan designates the project area for open space land uses. The project area is zoned Open Space (OS‐1XL), which allows for the development of parks and recreational facilities, natural resource preserves for the managed production of resources, marine and ecological preserves, public water supply reservoirs, water conservation areas and sanitary landfill sites that have received certificates of closure in compliance with federal and state regulations.
Griffith Park is in a very high fire hazard severity zone due to its high percentage of brush. In 2007, a fire burned a large segment, approximately 817 acres, within the central wilderness portion of the Park. Although most of the structures within the impacted area survived, the majority of the plant life was burned.
Griffith Park is within the Los Angeles River Watershed. The Los Angeles River Watershed is approximately 834 square miles in area and extends from the eastern portions of the Santa Monica Mountains, Simi Hills, and Santa Susana Mountains to the San Gabriel Mountains on the west. The Los Angeles River Watershed encompasses and is shaped by the path of the Los Angeles River, which flows from its headwaters in the mountains eastward to the northern corner of Griffith Park where the channel turns southward through the Glendale Narrows before it flows across the coastal plain toward Long Beach. Birds are among the most numerous and conspicuous wildlife species in Griffith Park (Urban Forest Program, October 2004). Approximately 200 bird species have been recorded including:
California towhee (Melozone crissalis)
black phoebe (Sayornis nigricans)
Anna’s hummingbird (Calypte anna)
red‐tailed hawk (Buteo jamaicensis)
red‐shouldered hawk (Buteo lineatus)
Reptiles including:
western fence‐lizard (Sceloporus occidentalis)
coastal whip tail (Aspidoscelis tigris stejnegeri),
western rattlesnake (Crotalus oreganus)

Mammals including:
coyote (Canis latrans)
raccoon (Procyon lotor)
striped skunk (Memphitis memphitis)
mule deer (Odocoileus hemionus)
California ground squirrel (Otospermophilus beecheyi)
Audubon cottontail (Sylvilagus audubonii)
Project Alternative Setting All project alternative sites are located within Griffith Park and all alternatives propose to remove and replace matures trees, relocate picnic tables, and construct youth baseball fields. The project footprint for all three alternatives are relatively level, located within a park setting, are currently vegetated with ornamental and native trees and turf grass, and are heavily irrigated. Ornamental and nonnative landscape areas occur within and near many of the high‐use areas including the alternative areas. This broad category includes horticultural trees, shrubs and lawns. Some native trees exist, but many exotic trees and shrubs have been introduced.

Environmental Impact Analysis The alternative project sites were visited by a biologist and an arborist on separate days. The results of those reconnaissance site assessments are presented below.
Methodology
General Biological Assessment The project sites were evaluated for the presence, absence, and likelihood of occurrence of special‐status species and vegetation types, and for more general biological resource issues potentially posing a constraint to the project through applicable laws and regulations. Accessible, adjacent areas were examined to provide context. Focused surveys for plants or wildlife were not performed during this reconnaissance site visit. Parameters for special‐status plants included topography, soil conditions, elevation, hydrology, and life history needs for the specific species. Special‐status parameters for wildlife include connectivity to documented and potentially occurring habitat, hydrology, access to the site, foraging and nesting habitat, the site’s operational activities, and life history needs for each species.
The site visit was conducted by ICF International biologist Kim Boydstun on August 1, 2013, from 1:30 p.m. to 5:45 p.m. Conditions were fair, with clear skies; temperature ranged from 80°F to 84°F; and the wind was 0 to 2 miles per hour. The site visit was performed by walking the alternative site locations and visually assessing all areas. The biologist walked the project sites and obtained 100% visual coverage. Field notes were compiled including conditions, visible disturbance factors, species, vegetation types, and more general biological resource issues observed or detected. Common plant species observed were identified by visual characteristics and morphology in the field. Wildlife species were detected by sight, call, tracks, scat, or other sign.
Reconnaissance Tree Survey An arborist survey was conducted at the project alternatives sites on August 28, 2013, by a “tree expert” as defined by the City of Los Angeles Standard Tree Removal Application Checklist. See Appendix B for verification of the current license and certification qualifying the “tree expert.”
The arborist survey methods followed standard professional practices. All tree location data were collected with a global positioning system unit. Trees within the defined areas of project disturbance, overhanging the project area, and greater than 4 inches in diameter breast height (DBH) were surveyed. Each tree was assigned an individual number for tracking purposes, but the trees were not physically tagged. Each tree was photographed. A photo of each protected tree that requires removal is included in Appendix C.
Literature Search for Threatened or Endangered Species A search of the CNDDB identified six wildlife and plant species federally and state‐listed as endangered, threatened, or candidate, with potential to occur within the Burbank U.S. Geological Survey (USGS) quadrangle, as presented in Table 1 (CNDDB 2013). At the time of the reconnaissance site visit, no threatened or endangered plant or wildlife species were observed.

Thresholds of Significance According to Appendix G of the State CEQA Guidelines, a project would have a significant impact related to biological resources if it would:
a. Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service;
b. Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Wildlife or US Fish and Wildlife Service;
c. Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means;
d. Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites;
e. Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance; or
f. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan.
In addition to the thresholds identified in Appendix G, the L.A. CEQA Thresholds Guide holds that the a project would normally have a significant impact if it would result in:
a. The loss of individuals, or the reduction of existing habitat, of a state or federally listed endangered, threatened, rare, protected, or candidate species, or a Species of Special Concern or federally listed critical habitat;
b. The loss of individuals or the reduction of existing habitat of a locally designated species or a reduction in a locally designated natural habitat or plant community;
c. Interference with wildlife movement/migration corridors that may diminish the chances for long‐term survival of a sensitive species;
d. The alteration of an existing wetland habitat; or
e. Interference with habitat such that normal species behaviors are disturbed (e.g., from the introduction of noise, light) to a degree that may diminish the chances for long‐term survival of a sensitive species.
Construction Impacts
Trees
A total of 179 trees were recorded during the tree survey. The location of each tree is shown in Figures 6 through 9. Specific information pertaining to each tree is provided in Tables 2 through 4, which are presented at the end of this report. Construction impacts to trees were based on conceptual ball field layouts in Figures 3 through 5.

Construction of the project would result in the removal and direct disturbance of numerous trees considered protected by the City of Los Angeles Tree Preservation Ordinance, the RAP Tree Preservation Policy, and the City’s Policy for the Installation and Preservation of Landscaping and Trees on Public Property. In all project alternatives protected trees are located in the footprint of ball fields where construction activities including raising and lowering existing grades, trenching for irrigation, and excavation for associated park facility improvements will require tree removal.
Additional effects on protected trees could occur during construction as a result of damage to trees located adjacent to the construction footprint. Activities conducted within the dripline of trees, such as trenching or grading, movement of construction vehicles and equipment, and spillage or dumping of fuel, oil, concrete, or other harmful substances, could result in damage to root systems and possible tree mortality.
The removal or harming of protected trees as a result of construction activities with any of the project alternatives would conflict with the City of Los Angeles Tree Preservation Ordinance, the RAP Tree Preservation Policy, and the City’s Policy for the Installation and Preservation of Landscaping and Trees on Public Property, and this would be a significant effect. However, removed trees would be replaced in accordance with City policy and coordination and authorization from RAP’s Urban Forestry Division would be required for any park trees and other vegetation that is removed by the proposed project. Applicable best management practices (BMPs), as described in the RAP Urban Forest Program, would be followed, including planning proactively, installing protective tree fencing, establishing a tree protection zone, installing a root buffer and mulch, maintaining irrigation or adequate soil moisture, establishing erosion control measures, conducting proactive pruning, trenching with alternative methods, and installing alternative types of hardscape.
Alternative 1, Option A – Crystal Springs North
Sixty‐seven (67) trees were surveyed for Alternative 1 Option A. Based on the conceptual layout prepared for this alternative, it is estimated that 45 trees would require removal during the construction process. Four trees may be temporarily affected from pruning or root disturbance during the construction process, but could require removal depending on the actions of the construction contractor, how closely BMPs are followed, and if unforeseen design changes would be required. Three trees would be temporarily affected during the construction process and would require BMPs to be successfully preserved. Fifteen (15) trees are located across the parking area and would likely not be affected at all by construction of this alternative, but temporary construction fencing should be erected around these trees as an extra precaution.
Of the 45 trees targeted for removal, 15 trees are protected under the Los Angeles Tree Protection Ordinance or the RAP Tree Preservation Policy. The impacted species each have the following number of trees and total trunk diameter required for removal: Black Walnut, three trees – 102 inches; California Sycamore, eight trees – 319 inches; and Coast Live Oak, one tree – 47 inches. See Table 2 for the complete protection status of the trees requiring removal.
With compliance with City policies regarding protected trees, this impact would be less than significant.

ICF 00327.13
Alternative 1, Option B – Crystal Springs South
Seventy‐seven (77) trees were surveyed for Alternative 1 Option B. Based on the conceptual layout prepared for this alternative, it is estimated that 68 trees would require removal during the construction process. Two trees may be temporarily affected from pruning or root disturbance during the construction process, but could require removal depending on the actions of the construction contractor, how closely BMPs are followed, and if unforeseen design changes would be required. Seven trees would be temporarily affected during the construction process and would require BMPs to be successfully preserved.
Of the 68 trees targeted for removal, 13 trees are protected under the Los Angeles Tree Protection Ordinance or the Department of Recreation and Parks Tree Preservation Policy. The impacted species each have the following number of trees and total trunk diameter required for removal: Evergreen Ash, three trees – 120 inches; Fremont Cottonwood, four trees – 88 inches, California Sycamore, four trees – 23 inches; and Coast Live Oak, two trees – 14 inches. See Table 3 for the complete protection status of the trees requiring removal.
With compliance with City policies regarding protected trees, this impact would be less than significant.
Alternative 2 – North Atwater Park
Thirty‐five (35) trees were surveyed for Alternative 2. Based on the conceptual layout prepared for this alternative, it is estimated that 28 trees would require removal during the construction process. Two trees may be temporarily affected from pruning or root disturbance during the construction process, but could require removal depending on the actions of the construction contractor, how closely BMPs are followed, and if unforeseen design changes would be required. Five trees are located next to the adjacent equestrian facility, downslope from the existing ball field, and would likely not be affected at all by construction of this alternative; but temporary construction fencing should be erected around these trees as an extra precaution.
Of the 28 trees requiring removal, four trees are protected under the Los Angeles Tree Protection Ordinance and the RAP Tree Preservation Policy. The trees impacted at this site are all California sycamore with 46 inches total trunk diameter. See Table 4 for the complete protection status of the trees requiring removal.
With compliance with City policies regarding protected trees, this impact would be less than significant.
Vegetation Cover
Vegetation at the alternative sites consists of turf grass surrounded by landscaped areas, planted ornamental and native trees as well as weedy vegetation was recorded along the edges of the driveways and parking lot areas at each alternative location. A shallow drainage channel, which has recently been restored, is located off‐site but directly west of the Alternative 2 site may contain surface water during the rainy season. This area has been planted and is currently being irrigated. Significant impacts not occur on riparian habitat or other sensitive natural communities identified in local or regional plans, policies, and regulations by CDFW or USFWS.

Wildlife
The criteria for determining significant impacts to wildlife includes substantial disruption of wildlife corridors; substantial interferences with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites; and damage to wildlife or their habitat.
Common bird species observed during the site visit include black phoebe, Anna’s hummingbird (Calypte anna), California towhee (Melozone crissalis), western scrub jay (Aphelocoma californica), and American crow (Corvus brachyrhynchos). Construction of the youth baseball fields would result in disturbance and removal of trees as described above. These trees may provide limited nesting habitat for migratory birds, which are protected under the Migratory Bird Treaty Act. In order to avoid impacts to migratory birds during the nesting season, mitigation would be required.
The site is located adjacent to urban and highly developed areas. Wildlife adapted to urban areas, such as crows, raccoon (Procyon lotor), and opossums (Didelphimorphia sp.) may traverse through the alternative project sites searching for food and shelter, but these commons species are not likely to utilize the site itself for nesting or denning. The alternative sites are located adjacent to the area of Griffith Park that is designated as SEA‐37, but none of the alternative sites are a part of the SEA. None of the alternative sites function as a wildlife corridor.
Impacts associated with project development would not substantially inhibit the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites. There are no migratory wildlife corridor for wildlife within the project sites and the project would not impede any wildlife nursery sites.
Wetlands
No wetlands exist within or adjacent to any of the alternative sites, therefore, no significant impacts on wetlands would occur and no environmental mitigation commitments are required. Impacts associated with project development would not occur to federally protected wetlands as defined by Section 404 of the CWA because direct removal, fill, or hydrological interruption will not occur because of project development. There are no wetlands within or adjacent to the alternatives sites.
Operational Impacts
Trees
Under both of the alternatives, it is anticipated that after project construction the project area would be maintained and irrigated in the same manner as prior to construction. The area is currently irrigated regularly, planted with turf grass, and used for recreation. The impacts of the operations of the proposed facilities are expected to have the same effect on the tree resources as current operations. No impacts on trees are expected during project operation.
Other Biological Resources
Operation of the proposed project would not significantly affect wildlife travel routes and movement, including migratory birds. Therefore, no further discussion of operational impacts on biological resources is necessary.

Mitigation Measures Alternative 1 Option A – Crystal Springs North
Nesting Birds
MM‐1 Mitigation Measure for Protection of Nesting Birds.
Construction activities that involve tree removal or trimming would be timed as much as possible to occur outside the migratory bird nesting season, which occurs generally from March 1 through August 31, and as early as February 1 for raptors.
If construction must occur during the migratory bird nesting season that would remove or disturb suitable nesting habitat, one biological survey would be conducted within 72 hours prior to construction, or if observed during construction activities. The surveys would indicate the presence or absence of any protected native birds in the habitat to be removed and any other habitat within 300 feet of the construction work area. If a protected native bird is found, surveys would be continued in order to locate any nests. If an active nest is found, construction within 300 feet of the nest (500 feet for raptor nests) would be postponed until the nest is vacated and juveniles have fledged (minimum of six weeks after egg‐laying), and there is no evidence of a second attempt at nesting. The buffer may be reduced by the monitoring biologist based on site‐specific conditions, including the bird species and nest location (e.g., within the vicinity of developed areas, taking into consideration the site’s pre‐construction noise and activity levels, etc.).
Alternative 1 Option B – Crystal Springs South
Nesting Birds
MM‐1 Mitigation Measure for Protection of Nesting Birds.
Under Alternative 1 Option B, this mitigation measure would be the same as that described for Alternative 1 Option A.
Alternative 2 – North Atwater
Nesting Birds
MM‐1 Mitigation Measure for Protection of Nesting Birds.
Under Alternative 2, this mitigation measure would be the same as that described for Alternative 1 Option A.
Significant Unavoidable Impacts Implementation of the mitigation measures identified above would reduce potential impacts to less‐than‐significant levels. Therefore, there would be no significant unavoidable impacts to biological resources.

ICF 00327.13
Cumulative Impacts CEQA defines cumulative impacts as two or more individual actions that, when considered together, are considerable or will compound other environmental impacts. Cumulative impacts are the changes in the environment that result from the incremental impact of development of the proposed project and other nearby projects. The study area for cumulative impacts to biological resources is defined for this project as the Griffith Park and Los Angeles River Narrows areas of Los Angeles. In this area, construction activities associated with the project alternatives would disturb biological resources existing in the project area and, thereby, contribute to the progressive loss of biological resources.
All significant impacts identified in the analysis have been mitigated to less‐than‐significant levels. The incremental effects of the proposed project, after mitigation, would not contribute to a significant adverse cumulative impact to biological resources. With mitigation, all project‐related impacts would be reduced to a less‐than‐significant level; therefore, the alternatives’ contribution to significant cumulative impacts would be rendered less than cumulatively considerable.
