C -, \"/" 7 ; � DeVity ty Clerk and ex -officio Clerk of theuncilof the City of Costa Mesa EXHIBIT "A" FINDINGS A. The information presented substantially complies with Costa Mesa Municipal Code Section 13-29(g)(5) in that the proposed model train railroad expansion project involves minor changes to the Fairview Park Master Plan, and the Fairview Park Master Plan, including the proposed amendment, meets the broader goals of the 2000 General Plan and the Zoning Code by exhibiting excellence in design of the railroad alignment, site planning, integration of uses and structures, and protection of the integrity of neighboring development. B.. The adoption of the mitigated negative declaration for the proposed project substantially complies with Article 6, Section 15074, of the California Environmental Quality Act (CEQA) in that the City Council considered the mitigated negative declaration together with any comments received during the public review process. City Council approval of the mitigated negative declaration is based on the whole, record (including the initial study and any comments received), and on the finding that there is no substantial evidence the project will have a significant effect on the environment and that the mitigated negative declaration reflects the City of Costa Mesa's independent judgment and analysis. A.PPL. PA -02-09 EXHIBIT "B" MITIGATION MONITORING PROGRAM Mitigation Measure IV -1: The Fairview Park Master Plan requires the City of Costa Mesa to restore large areas of native grassland habitat during the Master Plan's phased implementation. The City of Costa Mesa shall mitigate impacts to 0.05 acre of native grassland as a result of the proposed railroad track expansion at a 2:1 ratio through the creation of an additional 0.10 acre of native grassland habitat within the northeast side of Fairview Park. The start date of grassland restoration activity in Fairview Park has not been specified at this time; however, the creation of 0.10 acre of native grasslands shall occur within the first two years in which restoration activities are scheduled to commence. Mitigation Measure /V-2: If construction activity occurs from March 15 to August 15, the applicant shall retain a qualified biologist to survey the project site for the presence of any occupied nests within the immediate vicinity of the proposed railroad expansion, no more than three days prior to any construction work. If active nests of migratorybirds are located, the biologist shall determine measures to ensure protection of nesting migratory birds (including avoidance of the nest or temporary work stoppage). These measures shall depend on factors such as the bird species and construction schedule. The monitoring biologist shall determine construction buffer zones for active nests, if required. Mitigation Measure /V--3: If construction activity occurs from November 15 to March 15 (burrowing owl wintering season), the applicant shall retain a qualified biologist to perform preconstruction surveys on a weekly basis beginning the first week of November to determine if a burrowing owl has arrived at the site. If the qualified biologist determines that the site is not occupied by a burrowing owl, no additional measures would be necessary. If a burrowing owl occupies the site, no large equipment shall be operated in the vicinity of the occupied habitat and that section of track adjacent to the occupied habitat be install by hand. A biological monitor shall flag the occupied habitat that should be fenced or marked with yellow rope and T -bar to limit incursions into occupied areas. If construction work is occurring within 300 feet of the occupied burrow(s), the biologist shall conduct daily monitoring visits to ensure that encroachment into the area does not occur. Furthermore, the biologist shall verify that the new railroad track is not within a 160 -foot radius of the wintering owl's primary burrow. Mitigation Measure /V--4: The applicant shall ensure that no large equipment be operated in the vicinity of vernal pool A. Prior to the start of any construction activity, the. applicant shall temporarily fence or rope with T -bar the area along vernal pool A to limit potential impacts to the vernal pool basin. The applicant shall require the construction contractors, or other appropriate personnel, install by hand any section of the railroad track adjacent to vernal pool A. 16 APPL. PA -02-09 Mitigation Measure /X-1: The applicant shall submit a planning application for an amendment to the Fairview Park Master Plan and obtain approval of the planning application from the City of Costa Mesa, pursuant to procedures specified in Council Policy No. 500-11. 17 EXHIBIT -C" ADDED PAGES TO THE FAIRVIEW PARK MASTER PLAN- SUMMARY OF AMENDMENTS TO FAIRVIEW PARK MASTER PLAN Resolution No. Date of Adoption Description of Amendment: In November of 2002, City Council approved Planning Application PA -02-09, an amendment to the Fairview Park Master Plan for 2,250 lineal feet of new railroad track to be added to the existing 8,800 lineal feet of model train railroad track used for train rides on the east side of Placentia Avenue. Figure 1 attached to this table shows the Orange County Model Engineers' (OCME) model train railroad track expansion project. In August of 2002, the City of Costa Mesa engaged Tony Bomkamp, Senior Biologist of Glenn Lukos, Associates, to evaluate biological resources associated with expansion of the Orange County Model Engineer's Model Railroad Facility. The biological survey includes discussion related to the presence of a wintering burrowing owl, native grassland, and two vernal pools in the northeastern portion of Fairview Park. In November, 2002, City Council amended the. Fairview Park Master Plan to include this biological evaluation as Addendum No. 1. Please refer to Addendum No. 1 for detailed information related to existing biological resources in the vicinity of the Model Railroad Facility and an exhibit of the expanded alignment of the model train railroad track. Adopted in November, 2002, the Initial Study/Mitigated Negative Declaration for the project is available at the City of Costa Mesa, Development Services Department, for review.

CITY OF COSTA MESA DETERMINATION On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the' environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect: (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects: (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided- or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures.that are imposed upon the propose project, nothing further is required. Signat e CLAIRE L. FLYNN, AICP, ASSOCIATE PLANNER Title � :/2 1 Z02- Date Initial Study S& Page 2 Initial Study/Mitigated Negative Declaration Proposed Expansion of Orange County Model Engineers' Railroad Track Fairview Park Master Plan On December 15, 1997, the Costa Mesa City Council adopted the Fairview Park Master Plan and incorpo- rated related information into the Parks, Recreation, and Open Space Master Plan Element of the Costa Mesa General Plan. The Master Plan describes development of Fairview Park for low intensity uses. Facilities are provided for individual and small group activities for nature walks, bicycling, picnicking, model glider air- plane flying, and riding the model railroad. The passive uses included in the Master Plan support the need to protect unique archaeological and biological resources. The concept of the Master Plan emphasizes a rela- tively undisturbed natural setting and -minimal intrusion of built structures. Bicycle and hiking trails provide linkages to the 90 -acre Talbert Nature Preserve and the Santa Ana River system of trails and parks. All amendments to the Fairview Park Master Plan must be approved by City Council. Project Site Located in northwest portion of Costa Mesa, Fairview Park consists of 208 acres of open space bounded by the Santa Ana River (west), residential and institutional uses (north and south), and Costa Mesa:Golf Course (east). The OCME railroad is located on a 25 -acre site at the northern portion of east Fairview Park. Over three miles of narrow gauge track, bridges, station paving and work area are in currently in place (Exhibit 1). Proposed Project Beginning in 1988, the model train facility was installed as a volunteer project over a ten year period. The Orange County Model Engineers are a club of enthusiasts who own model trains and have constructed the train facility at no cost to the City of Costa Mesa. This extensive narrow gauge rail system is open to the general public at no charge, every third weekend each month for 5 % hours a day. Other weekends are used for system maintenance and entertainment of private parties on a reservation basis. The model train railroad serves 45,000 to 60,000 visitors a year. In addition to its weekend activities, the OCME hosts school grops, parent-child groups, Scout troops, Cub packs, service clubs, and other organiza- tions for private parties. On a typical weekend, the facility hosts 2,000-4,000 visitors. The OCME is requesting to expand the model train railroad track system at Fairview Park. An additional 2,250 lineal feet of railroad track will be added to the existing 8,800 lineal feet of track, used for train rides on the east side of Placentia Avenue (Exhibits 2 and 3). The entire narrow guage railroad track at the Model Train Facility is aproximately 3 miles in length, including track not used for train rides. The proposed pro- ject is a logical expansion of the current track system. Since it was not included as part of the conceptual layout of Fairview Park, an amendment to the Master Plan is required.

EVALUATION OF ENVIRONMENTAL IMPACTS DISCUSSION: The Model Train Railroad Facility at Fairview Park encompasses 25 acres of land and is located north and east of Placentia Avenue, south of Fairview Channel, and west of the Costa Mesa Golf Course. The northeastern park area contains steep slopes in the vicinity of Fairview Channel. The proposed project involves installation of additional model train -railroad -track only. :No aesthetic impacts are associated with the proposed project, therefore, no mitigation measures related to aesthetics are required. SOURCES: Fairview Park Master Plan, March 1998 II. AGRICULTURAL RESOURCES. Would the project: (a) Convert prime farmland, unique farmland, or farmland.of statewide importance (Farmland), as shown on the maps prepared pursuant to the- Farmland .Mapping- and- Monitor- -- - - - ing Program of the California Resources Agency, to non- agricultural use? (b) Involve other changes in the existing environment which, ❑ El Q due to their location or nature, could result in conversion of Farmland, to non-agricultural use? DISCUSSION: No agricultural resources or operations currently exist within the project site; therefore, no significant im- pacts to agricultural resources or operations would result with project implementation. No mitigation measures are required. SOURCES: Fairview Park Master Plan, March 1998 City of Costa Mesa 2000 General Plan Biological Report, Glenn Lukos Associates, Inc., September, 2002 III.

Initial Study Page 5 Less Than Significant Potentially With Less Than Significant Mitigation Significant No TOPICS Impact Incorporated Impact Impact DISCUSSION: Biological Survey Biologists from Glenn Lukos Associates, Inc. (GLA) conducted biological surveys of the project site from August 12-15, 2002. The biological evaluation specifically included surveys for burrowing owls, vegetation mapping of native grassland areas along the proposed railroad track, and a general review of the proposed expansion area for any special -status species or habitats capable of supporting special -status species. Since the review was conducted in mid -summer of a low rainfall year, the assessment of the site was limited to those resources that were present at the time of site surveys or resources that were documented from the site during surveys conducted earlier in the season. The biological report is provided as Attachment 1. Native Grassland The biological report indicates that two patches of native grassland dominated by purple needle grass (Nasella pulchra) were identified in the northern portion of the property along the proposed railroad align- ment. The first patch is approximately 100 square feet (0.002 acre) and occurs five feet upslope from the proposed alignment. The second patch is approximately 2,250 sq.ft. (0.05 acre) and is located on both sides of the proposed railroad. The native grassland areas are identified in Exhibit 4. In addition to the areas of needle grass, two areas of degraded salt grass (Distichlis spicata) meadow were identified along the pro- posed railroad alignment. These areas support a sparse cover of salt grass mixed with wild oat (Avena sp.), rigut brome (Bromus diandrus), sweet fennel, and black mustard. The Fairview Master Plan has been divided into areas for phased construction based upon type of use or type of habitat restoration. Located on 69.64"acres- in the western portion of Fairview -Park, Area D (Exhibit -5)`is an environmentally sensitive area including California native grasslands, vernal pools, and coastal bluff scrub. The Master Plan requires restoration of native grasslands at the time of fill soil removal from desig- nated archaeological site areas. During this restoration effort, creation of an additional .10 acre of native grasslands in Area D will adequately replace the 0.05 acre of native grassland areas impacted by the pro- posed project. Wintering Owl The western burrowing owl is a California Department Fish and Game designated state species of special concern. On February 14, 2002, a California Department of Fish and Game (CDFG) biologist observed one burrowing owl at the entrance of an abandoned California ground squirrel burrow located near the top of a gully facing Placentia Avenue. Because it has been established that one burrowing owl was observed on site, a habitat assessment for the burrowing owl was not required. Subsequent protocol surveys conducted from August 12-15 by GLA biologists concluded that the "wintering owl" was not a year-round resident. According to the "burrowing owl survey protocol and mitigation guidelines", the burrowing owl nesting season occurs between February 1 to August 30, with the peak breeding season occurring between April 15 to July 15. The peak of the wintering season occurs between December 1 and January 31, but in southern California, this bird will often winter later into the season, sometimes into the second week of March.

The biologists surveyed the entire area of the proposed alignment of the railroad track. The western burrow- ing owl was not identified during focused surveys, nor was physical evidence detected within the survey area, including at the pre -identified burrowing owl location. The biological report concluded that the survey area is occupied by a wintering owl only. Expansion of the railroad track would not measurably change the amount of foraging habitat for wintering burrowing owls nor would the expansion directly affect the bur- rows identified as occupied. The proposed alignment of the railroad track in the vicinity of the owl burrow is 15-20 feet west of the existing railroad track. The CDFG biologist observed a burrowing owl 100 feet west of the existing track. There are no direct, long-term impacts related to wintering (or year-round resi- dent) owls on the project site. Therefore, no mitigation measures are required for long-term impacts. Vernal Pools Sensitive habitats occurring within the vicinity of the project site include: southern coastal salt marsh, southern cottonwood willow riparian forest, and southern dune scrub. None of these sensitive biological resources occur on the project site. However, the site does support three vernal pools that occur in the vicin- ity of the existing railroad facility (Exhibit 4). Vernal Pool "A" is an approximately 10 -foot by 40 -foot ver- nal pool located immediately inside the existing railroad track alignment. The vernal pool is located adja- cent to portions of track that will be move during the expansion project. The vernal pool was identified based on the presence of a dense cover of woolly marbles, a vernal pool indicator plant. Vernal pools are considered habitat for western spade -foot toad and San Diego fairy shrimp. Vernal Pools `B" and "C" were observed in the southwest portion of the site near Placentia Avenue. The pools are located near the existing railroad facility on.the southeast side from where the railroad alignment is proposed. The approximate limits and location of these pools are depicted in Exhibit 4. The vernal pools were identified based on the presence of woolly marbles within a series of depressions. No other vernal in- dicator plants were identified during the site reconnaissance. Vernal pools B and C are outside the proposed area of track expansion, no impacts to vernal pools are anticipated. The operation of the proposed railroad track is not expected to have any long -teen impacts to these three identified vernal pools. Therefore, no mitigation measures are required. IMPACTS Less than significant impacts with mitigation incorporated Impact IV -1: The implementation of the proposed railroad track would impact up to 0.05 acres of native grassland supporting purple needle grass. Impact IV -2: Migratory birds may have active nests in Fairview Park in the vicinity of the project site from March 15 to August 15. These active nests may be impacted by short-term construction activity related to railroad track installation. tv/5-4 Initial Study Page 7 Less Than Significant Potentially With Less Than Significant Mitigation Significant No TOPICS Impact Incorporated Impact Impact Impact IV -3: Temporary, construction -related impacts to the wintering burrowing owl may occur if con- struction activity takes place from November 15 to March 15 (burrowing owl wintering season). No long- term Impact IV -4: Potential western spade -foot toad and San Diego fairy shrimp habitat occur within vernal pool A, which may be temporarily impacted during short-term construction activity. MITIGATION MEASURES Mitigation Measure IV -1: The Fairview Park Master Plan requires the City of Costa Mesa to restore large areas of native grassland habitat during the phased implementation of the Master Plan. The City of Costa Mesa shall mitigate impacts to 0.05 acre of native grassland as a result of the proposed railroad track expan- sion at a 2:1 ratio through the creation of an additional 0.10 acre of native grassland habitat within Area "D" (western portion of Fairview Park), an area designated for grassland restoration as a component of imple- menting the Fairview Park Master Plan. The start date of grassland restoration activity in Fairview Park has not been specified at this time; however, the creation of 0.10 acre of native grasslands shall occur within the first two years in which restoration activities are scheduled to commence. Mitigation Measure IV -2: If construction activity occurs from March 15 to August 15, the applicant shall retain a qualified biologist to survey the project site for the presence of any occupied nests within the imme- diate vicinity of the proposed new track, no more than three days prior to any construction work. If active nests of migratory birds are located, the biologist shall determine measures to ensure protection of nesting migratory birds (including avoidance of the nest or temporary work stoppage). These measures shall depend on factors such as the bird species and construction schedule. The monitoring biologist shall determine con- struction buffer zones for active nests, if required. Mitigation Measure IV -3: If construction activity occurs from November 15 to March 15 (burrowing owl wintering season), the applicant shall retain a qualified biologist to perform preconstruction surveys on a weekly basis beginning the first week of November to determine if a burrowing owl has arrived at the site. If the qualified biologist determines that the site is not occupied by a burrowing owl, no additional measures would be necessary. If a burrowing owl occupies the site, no large equipment shall be operated in the vicin- ity of the occupied habitat and that section of track adjacent to the occupied habitat be installed by hand. A biological monitor shall flag the occupied habitat that should be fenced or marked with yellow rope and T - bar to limit incursions into occupied areas. If construction work is occurring within 300 feet of the occupied burrow(s), the biologist shall conduct daily monitoring visits to ensure that encroachment into the area does not occur. Mitigation Measure IV -4: The applicant shall ensure that no large equipment be operated in the vicinity of vernal pool A. Prior to the start of any construction activity, the applicant shall temporarily fence or rope with T -bar the area along vernal pool A to limit potential impacts to the vernal pool basin. The applicant shall require the construction contractors, or other appropriate personnel, install by hand any section of the railroad track adjacent to veinal pool A.

Would the project: (a) Cause a substantial adverse change in the significance of a El El ❑ Z historical resource as defined in Title 13, Chapter IX, Article 14 of the Costa Municipal Code? (b) Cause a substantial adverse change in the significance of ❑ an archaeological resource pursuant to CEQA Guidelines, Section 15064.5? (c) Directly or indirectly destroy a unique paleontological re- source or site or unique geologic feature? (d) Disturb any human remains, including those interred out- side of formal cemeteries? DISCUSSION: Fairview Park contains two listed archaeological sites which have been investigated and documented. CA -ORA -58 occupies the northwestern bluff top of the site, west of Placentia Avenue. CA -ORA -506 lies --- to the east of CA -ORA -58 and is east of Placentia Avenue in the general area of the model train railroad extending north to the Canary Drive area. Of the two sites, CA -ORA -58, the bluff --top site, has been the subject of greater attention through archaeological study and preservation methods. CA -ORA -506 is con- sidered a low-density archaeological area. The proposed project involves expansion of an existing train facility in a low-density archaeological area. No substantial alteration to the existing topography or disturbance of any known paleontological resources or unique geologic feature is anticipated. The Fairview Park Master Plan requires that any new heavy construction in the northern vicinity of the train operation be monitored and studied by a certified archae- ologist. Since project construction does not involve major excavation or large construction equipment, impacts on archaeological resources are considered less than significant, and a monitoring archaeologist is not required.

Would the project: G 8' Initial Study Page 9 DISCUSSION: As with most of Southern California, Costa Mesa is subject to some seismic activity. However, the extent of damage will depend on the distance of the seismic sources as well as the extent of the motion. The four ma- jor faults or zones that present a seismic hazard for Costa Mesa are: the Newport -Inglewood Structural Zone, Whittier Fault Zone, San Andreas Fault Zone, and San Jacinto Fault Zone. The Newport -Inglewood Struc- tural Zone is approximately 3.5 miles wide within Costa Mesa and is considered to have a low probability of surface rupture. Furthermore, the implementation of the proposed project involves minimal soil disturbance. The project site is underlain by Miocene sedimentary bedrock covered by exposed marine and non -marine sediments of the Pleistocene Era and recent origin. Fairview Park soils are predominantly sand in lower elevations and silty clay loam/clay on the mesa area. No impacts to geology and soils are anticipated; therefore, no mitigation measures are required. SOURCES: Fairview Park Master Plan, March 1998 City of Costa Mesa 2000 General Plan VII.

The majority of the project site will be left in its current state. The additional railroad track will result in an increase of impervious surface by less than 5 percent. Stormwater runoff from the project site drains into the Fairview Channel. In the vicinity of the railroad are drain pipes that follow under the railroad and release runoff into the open channel. The northern section of the project site drains into an inlet attached to the storm drain line connected to Fairview Channel. The inlet is located at the intersection of the park, Placentia Avenue, and Fairview Channel Since adequate drainage is provided in the project area, no impacts to hydrology and water quality are anticipated. Therefore, no mitigation measures are required.

Initial Study Page 12 Less Than Significant Potentially With Less Than Significant Mitigation Significant No TOPICS Impact Incorporated Impact Impact DISCUSSION: The project site is located in the northeastern portion of Fairview Park, east of Placentia Avenue. Fairview Park is bounded by single-family residential uses (north and south), Santa Ana River (west), and the Costa Mesa Golf Course (east). A land use map is provided as Exhibit 6. On December 15, 1997, the Costa Mesa City Council adopted the Fairview Park Master Plan and incorporated related information into the Parks, Recreation, and Open Space Master Plan Element of the Costa Mesa General Plan. The concept of the Mas- ter Plan emphasizes relatively undisturbed natural setting and minimal intrusion of built structures. Bicycle and hiking trails provide linkages to the 90 -acre Talbert Nature Preserve and the Santa Ana River system of trails and parks. All amendments to the Fairview Park Master Plan must be approved by City Council. The additional railroad track is not part of the conceptual plan layout included in the approved park master plan. A future "bark park" area designated for running of dogs off -lease is located on 3.75 acres west of the rail- road facility. The proposed expansion area will not have a significant impact on the size and function of the future dog park. The Bark Park Foundation President expressed no concerns with the proposed model train railroad facility expansion. In addition, the project site does not contain any established communities or conflicts with any applicable habitat conservation plan or natural community conservation plan. Impact IX -1: The proposed installation of additional railroad track to the existing model engineers facility requires an amendment to the Fairview Park Master Plan. Council Policy No. 500-11, Implementation Pro- cedures for Fairview Park Master Plan, requires that amendments to the Master Plan are forwarded to the Parks and Recreation Commission and Planning Commission for review and recommendation. The Plan- ning Commission shall forward. its recommendations for final action to City Council. Mitigation Measure IX -1: The applicant shall submit a planning application for an amendment to the Fairview Park Master Plan and obtain approval of the planning application from.the City of Costa Mesa, pursuant to procedures specified in Council Policy No. 500-11.

The facility is operated every third Saturday and Sunday of the month for approximately 5 '/a hours a day. It has become a popu- lar feature of the park by providing free train rides to the general public each month and entertaining pri- vate gatherings at other times. The operations involve low traffic on the rails and minimal impact on landscape. The proposed project will not involve a significant increase in the number of park visitors. Therefore, no impacts to traffic and circulation are anticipated, and no mitigation measures are required. A condition of approval requiring the installation of railroad crossing warning signs at any point where the railroad track crosses an established trail will enhance safety for the facility's users.

It has become a popu- lar feature of the park by providing free train rides to the general public each month and entertaining pri- vate gatherings at other times. The operations involve low traffic on the rails and minimal impact on landscape. The proposed project will not involve a significant increase in the number of park visitors. Therefore, no impacts to traffic and circulation are anticipated, and no mitigation measures are required. A condition of approval requiring the installation of railroad crossing warning signs at any point where the railroad track crosses an established trail will enhance safety for the facility's users.

Initial Study `17 Page 17 Less Than Significant Potentially With Less Than Significant Mitigation Significant No TOPICS Impact Incorporated Impact Impact DISCUSSION: Implementation of mitigation measures related to biological resources will reduce any impacts to below a level of significance. Mitigation measures addressing monitoring wintering owl burrows, active nests of migratory birds, and vernal pools will minimize any harm to avian species/active nests, western spade foot toad, and San Diego fairy shrimp. In addition, the project site is considered a low-density archaeo- logical area. Since the proposed project involves minimal grading and disturbance of soils, no impacts related to archaeological resources are anticipated. No significant, cumulatively considerable impacts or adverse impacts to human beings are associated with implementation of the proposed project.

Flynn Associate Planner City of Costa Mesa P.O. Box 1200 77 Fair Drive Costa Mesa, California 92626 SUBJECT: Evaluation of Biological Resources Associated with Expansion of Model Railroad Facility at Fairview Park Dear Ms. Flynn: On August 12, 13, 14, and 15, 2002,. biologists from Glenn_Lukos Associates, Inc. (GLA) conducted a focused biological review of the proposed. model railroad expansion area. The biological review specifically included surveys for burrowing -owls, vegetation mapping of native grassland areas along the proposed railroad alignment,. and a general review of the proposed expansion area for any special -status species or habitats capable of supporting special -status species. Since the review was conducted in mid -summer of a low rainfall year, the assessment of the site was limited to those resources that were present at the time of site surveys or resources that were documented from the site during surveys conducted earlier in the season. I. SITE DESCRIPTION The Model Railroad Facility at Fairview Park site encompasses an envelope that covers approximately 25 -acres and is located north and east of Placentia Avenue, south of Fairview Channel, and west of Costa Mesa Golf Course. The project site is located in Orange County in the City of Costa Mesa [Exhibit 1 — Regional Map]. The study area addressed by this report includes all areas that may potentially be impacted by the proposed re -alignment of the model train tracks within Fairview Park; however, it should be noted that the actual impacts will be limited to a narrow corridor where the new tracks will be installed. The study area is located within Township 6S, Range l OW, of an unsectioned portion of Orange County, as depicted on the USGS quadrangle Newport Beach, California (dated 1965 and photorevised 1981)[Exhibit 2 —Vicinity Map]. 23712 Birtcher Drive Lake Forest California 92630-1782 Telephone; (949) 837-0404 Facsimile; (949) 837-5834 70 CID 0 3 C_ cn G) cn cn iv Z) w 0 c: Lv (D AM co on.for i y- �ARD R yl L Cl T WE T IN4E 1A oII VALLEY ib mney �PNTINdio MEACkf ...—Cos I Z 0 I Lido Islan r NSWPOR BEAU Y.

METHODOLOGY Evaluation of the property included a review of the California Natural Diversity Database' (CNDDB)', documents previously prepared that address biological resources in vernal pools on the west side of Placentia Avenuez, as well as the following field studies: (1) mapping native grassland areas occurring within the railroad expansion alignment; (2) general review of the site for special -status species and native habitats with the potential to support special -status species; (3) identification of all plant and wildlife species present during site reconnaissance; and (4) focused surveys for the western burrowing owl (Athene cunicularia). CNDDB and Literature Review Prior to conducting field studies, the CNDDB was reviewed for the U.S. Geological Survey (USGS) topographic map Newport Beach [dated 1965 and photorevised in 1981. Sensitive species reported in the project vicinity were noted and the project site was evaluated for the potential to support such species. In addition, documentation, regarding the vernal pools within the park but west of Placentia Avenue was reviewed to provide addition information regarding plants identified within or adjacent to the vernal pools within the park. Vegetation Mapping The alignment for the proposed railroad relocation was walked in order to identify all native grassland areas to be potentially impacted by the expansion. All areas were mapped in the field and then transferred to a 200 -scale topographic map depicting the proposed expansion alignment [Exhibit 3]. All other sensitive or otherwise notable habitats and species were also included in the mapping. All plant species present on site during the review were recorded in field notes. General Wildlife Surveys During the site visits, general observations were made of wildlife. Observations included sightings of wildlife as well as physical evidence (i.e., scat, tracks, burrows, etc.). All observations of wildlife were recorded in field notes. California Department of Fish and Game. August, 2002. Natural Diversity Database: RareFind 2. ' Michael Brandman Associates. 1995. Biological Surveys of Fairview Park Vernal Pools, Costa Mesa, Orange County, California. Claire L. Flynn City of Costa Mesa September 12, 2002 Page 3 Focused Surveys for Burrowing Owls On February 14, 2002, a California Department of Fish and Game (CDFG) biologist observed one burrowing owl at the entrance of an abandoned California ground squirrel burrow (Exhibit 3) located near the top of a gully facing Placentia Avenue (Exhibit 3). Because it has been established that one burrowing owl was observed on site, a habitat assessment for the burrowing owl was not required. On August 12, 13, 14, and 15, 2002, protocol surveys were conducted for the western burrowing owl (Athene cunicularia) by GLA biologist Jeff Ahrens and assisted by biologists Tony Bomkamp and Dave Moskovitz to confirm that the burrowing owl previously observed did not nest on site, was not a year-round resident and instead, conclude the burrowing owl observed in February was a wintering owl. The western burrowing owl is a CDFG-designated state species of special concern. :This fossorial owl occupies abandoned rodent burrows and man-made structures such as culverts, pipes, and debris piles occurring in open grassland habitats. According to the `Burrowing owl survey protocol and mitigation guidelines", the burrowing owl nesting season occurs between February 1 to August 30, with the peak of breeding occurring between April 15 to July 15. The peak of the wintering season occurs between December 1 and January 31, but in southern California, this bird will often winter later into the season, sometimes into the second week of March.3 Areas to be surveyed were identified based on a topographic map provided by the City of Costa Mesa, identifying the mapped location of the burrowing owl and by verbal confirmation from the identifying biologist. All of GLA biologists who visited the site are familiar with the habitat requirements of the burrowing owl. Focused burrowing owl surveys closely followed the "Burrowing owl survey protocol and mitigation guidelines" prepared by the California Burrowing Owl Consortium (1993) in which four comprehensive burrowing owl surveys of the subject site were conducted by thoroughly traversing the site on foot to identify all signs of the presence or absence of the burrowing owl (e.g., burrowing owl, its molted feathers, cast pellets, prey remains, eggshell fragments, or excrement at or near a burrow entrance). Prior to walking through suitable habitat, these areas were viewed from a distance with binoculars to look for owls perched near burrows. All physical evidence of owls and sightings of owls were recorded in field notes. All areas associated with the re -alignment of the railroad track were surveyed. 3 Bloom, Pete. 2000.

Flynn City of Costa Mesa September 12, 2002 Page 4 III. RESULTS OF BIOLOGICAL SURVEYS Vegetation Review At the time of the August site reconnaissance, the area of the proposed railroad alignment was dominated by non-native grasses and weeds. Non-native species identified during the site visit within the proposed alignment include sweet fennel (Foeniculum vulgare), black mustard (Brassica nigra), summer mustard (Hirsehfeldia incana), annual grasses (Avena sp, Bromzts sp., Hordeum sp.), Russian thistle (Salsola tragus), Australian saltbush (Atriplex semibaccata), horehound (Marrubium vulgare), tocalote (Centaurea melitensis), field bindweed (Convolulus arvensis), doveweed (Eremocarpus setiger), filaree (Erodium sp.), spurge (Chamaesyce sp.), and Bermuda grass (Cynodon dactylon). Native species include purple needlegrass (Nasella pulchra), salt grass (Distichlis spicata), fascicled tarplant (Deinandra fasciculata), and telegraph weed (Heterotheca grandiflora). Additional plants identified on site but notwithin the proposed railroad alignment include Boccone's sand spurry (Spergularia bocconei), curly dock (Rumex crispus), woolly marbles (Psilocarphus brevissimus), akali heliotrope (Heliotropum curassavicum), alkali mallow (Malvella leprosa), western ragweed (Ambrosia psilostachya), and gumplant (Grindelia sp.). Two patches of native grassland dominated by purple needlegrass (Nasella pulchra) were identified in the northern portion of the property along the proposed railroad alignment. The first patch is approximately 100 square feet (0.002 acre) and occurs five feet upslope from the proposed alignment. The second patch is approximately 2,250 square feet (0.05 acre) and straddles the proposed railroad alignment. These areas are depicted on the biological resource map [Exhibit 3]. In addition to the areas of needlegrass, two areas of degraded salt grass (Distichlis spicata) meadow were identified along the proposed railroad alignment. These areas support a sparse cover of salt grass mixed with wild oat (Avena sp.), ripgut brome (Bromus diandrtcs), sweet fennel, and black mustard. Special -Status Plants A review of the August 2002 California Natural Diversity Database (CNDDB) for the Newport Beach Quadrangle and the biological reports prepared for the onsite vernal pools identified nineteen special -status plant species as occurring within the vicinity of the project site. The potential for each species to occur on site is provided based on results of the analysis of the project site. Those species that have a potential to occur on site due to the presence of potential Claire L. Flynn* City of Costa Mesa September 12, 2002 Page 5 habitat are discussed in more detail. Those species that exhibit no potential for occurring on site are listed but not discussed. Prostrate Navarretia (Navarretia prostrata) — Prostrate navarretia is a California Native Plant Society (CNPS) List 1B species (rare, threatened, or endangered in California or elsewhere) that occurs in vernal pools, coastal scrub, and alkaline grasslands. The species is known from San Diego, Los Banos, Fairview Park in the City of Costa Mesa in the vernal pools west of Placentia Avenue, and the Santa Rosa Plateau in western Riverside County. Three vernal pools were identified in the vicinity of the railroad facility, but are not located within the proposed expansion alignment. Prostrate navarretia was not observed during site reconnaissance, but has the potential to occur based on the presence of suitable habitat and it presence in he nearby vernal pools. Spreading Navarretia (Navarretia fossalis) - Spreading navarretia is Federal -listed as threatened and is a CNPS List IB species. Spreading navarretia occurs ,vithin vernal pools, chenopodium scrub, playas, marshes and swamps, often surrounded by other habitat types. This species has not been previously identified in Orange County and was not observed in the three vernal pools identified in the vicinity of the railroad facility and importantly has not been observed in the vernal pools west of Placentia Avenue. Therefore this species is not expected to occur on the site. Little Mousetail (Myosurus minimus) — Little mousetail is a CNPS List 3 species (plants about which more information is needed) that occurs in vernal pools, and valley and foothill grassland. Little mousetail was not observed in the three vernal pools identified in the vicinity of the railroad facility, but has the potential to occur based on the presence of suitable habitat, and its known occurrence in the vernal pools west of Placentia Avenue. Mud Nama (Nama stenocarpum) — Mud nama is a CNPS List 2 species (rare, threatened, or endangered in California, but more common elsewhere) that occurs in marshes and swamps, and vernal pools. Mud nama was not observed in the three vernal pools identified in the vicinity of the railroad facility, but has the potential to occur based on the presence of, suitable habitat and its known occurrence in the vernal pools west of Placentia Avenue. Small -Flowered Microseris (Microseris douglasii var. platycarpha) — Small -flowered microseris is a CNPS List 4 species (plants of limited distribution) that occurs in coastal grassland areas. Small -flowered microseris was not observed during the review of the railroad expansion alignment. The majority of the areas within the alignment are disturbed, non-native habitats that are not expected to support this species. However, the native grassland areas within the proposed alignment do have the potential to support small -flowered microseris. Claire L. Flynn City of Costa Mesa September 12, 2002 Page 6 Other areas in the vicinity of the proposed railroad alignment are expected to support this species based on the presence of suitable habitat and its known occurrence in other areas of Fairview Park west of Placentia Avenue. Vernal Barley (Hordeum intercedens) — Vernal barley is a CNPS List 3 species that occurs in vernal pools, coastal dunes, coastal scrub, and saline flats and depressions within valley and foothill grassland. Vernal barley was not observed in the three vernal pools identified in the vicinity of the railroad facility, but has the potential to occur based on the presence of suitable habitat, and its known occurrence in and adjacent to the vernal pools west of Placentia Avenue. Additional special -status species which have been identified for the Newport Beach Quadrangle, include chaparral sand -verbena (Abronia villosa var.aurita), Aphanisma (Aphanisma blitoides), Coulter's saltbush (Atriplex coulteri), south coast saltscale (Atriplex pacifcca), Davidson's saltbush (Atriplex serenana var. davidsonii), southern tarplant (Centromadia parryi ssp. australis), San Fernando Valley spineflower (Chorizanthe parryi var. fernandina), salt marsh bird's, -beak (Cordylanthursmaritimus ssp. maritinuus), many -stemmed dudleya (Dudleya multicaulis), Los Angeles sunflower (Helianthus nuttallii ssp. parishii), Coulter's goldfields (Lasthenia glabrata ssp. coulteri), Robinson's pepper -grass (Lepidium virginicum var. robinsonii), and Coast woolly -heads (Nem'acaulis denudata var. denudata). None of the above mentioned special -status species were observed within the proposed railroad expansion alignment, and are not expected to occur due to a lack of suitable habitat. Sensitive Habitats A review of the August 2002 CNDDB for the Newport Beach Quadrangle identified the following sensitive habitats as occurring within the vicinity of the project site: southern coastal salt marsh, southern cottonwood willow riparian forest, southern dune scrub, and southern foredunes. None of these sensitive habitats occur on site. However, the site does support three vernal pools that occur in the vicinity of the existing railroad facility. The locations of each of these pools are depicted on Exhibit 3. Vernal Pool A An approximately 10 -foot -by -40 -foot vernal pool was identified immediately on the inside of the existing railroad track alignment. The vernal pool is located adjacent to portions of track that will be moved during the expansion project. The vernal pool was identified based on the presence of a dense cover of woolly marbles (Psilocarphus brevissimus) within a depression. The woolly marbles are remnants of the 2001 season, which is the last time this pool is thought Claire L. Flynn City of Costa Mesa September 12, 2002 Page 7 to have ponded. No other vernal pool indicator plants were identified during site reconnaissance. Vernal Pools B and C Two vernal pools were observed in the southwest portion of the site near Placentia Avenue. The pools are located near the existing railroad facility, but are on the other side of the facility from the where the railroad alignment is proposed. The square -footage of these pools were not determined, but their approximate limits and location are depicted on the enclosed biological resource exhibit. The vernal pools were identified based on the presence of woolly marbles within a series of depressions. The woolly marbles are remnants of the 2001 season, which is the last time this pool is thought to have ponded. No other vernal pool indicator plants were identified during site reconnaissance. General Wildlife Birds identified on or near the site include mourning dove (Zenaida macroura), American crow (Corvus brachyrhynchos), western kingbird (Tyrannus verticalis), house finch (Caipodacus mexicanus), American kestrel (Falcosparverius), and Anna hummingbird (Calvpte anna). Mammals detected on site either by physical evidence -or direct observation include California ground squirrel (Spermophilus beecheyi), domestic dog (Cam's familiaris), coyote (Canis latrans), desert cottontail (Sylvilagus auduboni), domestic cat (Felis catacs), and Botta's pocket gopher (Thomomys bottae). No reptiles or amphibians were observed on site. Special -Status Wildlife A review of the August 2002 CNDDB for the Newport Beach Quadrangle identified thirteen special -status wildlife species as occurring within the vicinity of the project site. The potential for each species to occur on site is provided based on results of the analysis of the project site. Those species that have a potential to occur on site due to the presence of potential habitat are discussed in more detail. Those species that have no chance to occur on site are listed but not discussed. Western Burrowing Owl (Athene cunicularia) - The western burrowing owl is a CDFG- designated state species of special concern. This fossorial owl occupies abandoned rodent burrows and man-made structures such as culverts, pipes, and debris piles occurring in open Claire L. Flynn City of Costa Mesa September 12, 2002 Page 8 grassland habitats. The western burrowing owl has been previously identified on site and the results of subsequent focused surveys are discussed in the results section. San Diego Horned Lizard (Phrynosoma coronatum blainvillei) - The San Diego horned lizard has been CDFG-designated as a state species of special concern. This lizard inhabits coastal sage scrub and chaparral in and and semi -arid climate conditions with friable, rocky, or shallow . sandy soils. The San Diego horned lizard was not observed on site and is not expected to occur on site due to a lack of suitable habitat. Coastal California Gnateatcher (Polioptila californica californica) - The coastal California gnatcatcher is a Federal -listed threatened species. This small songbird is a year-round resident associated with coastal sage scrub communities of southern California. A single coastal California gnatcatcher was detected audibly by biologists Jeff Ahrens (PRT -0521530) and Dave Moskovitz off site in Fairview Park, west of Placentia Avenue. The coastal California gnatcatcher is known to intermittently occupy areas of saltbush scrub near the western edge of the bluff in the portions of the Parkwest of Placentia Avenue.' Suitable habitat isnot present within the study area on the east side of Placentia Avenue. This species was not observed on site and is not expected to occur on site due to lack of suitable. habitat on' the east side of Placentia Avenue. Western Spadefoot Toad (Scaphiopus hammondit) - The western spadefoot toad is designated by CDFG as a State species of concern. The western spadefoot occurs primarily in grassland habitats, but can be found in valley -foothill hardwood woodlands. Vernal pools and other seasonally ponded areas are essential for breeding and egg -laying. Three vernal pools were identified in the vicinity of the railroad facility, but are not located within the proposed expansion alignment. The western spadefoot toad was not observed during site reconnaissance. Since the biological review was conducted in August of a low rainfall year, conditions were not present to adequately evaluate the presence/absence of the toad. However, the western spadefoot toad has the potential to occur on site based on the presence of suitable habitat. San Diego Fairy Shrimp (Branchinecta sandiegonensis) — The San Diego fairy shrimp is a Federally listed endangered species. This species is endemic to San Diego and Orange County mesas and requires vernal pools for breeding. Three vernal pools were identified in the vicinity of the railroad facility, but are not located within the proposed expansion alignment. Surveys for fairy shrimp were not conducted due to lack of ponding and because the vernal pools will be avoided by the project. San Diego fairy shrimp exhibits potential to occur in these pools based Bomkamp, Tony. 2002. Personal Observations during numerous site visits conducted between 1995 and 2002. Claire L. Flynn City of Costa Mesa September 12, 2002 Page 9 on the presence of suitable habitat and their occurrence with the pools west of Placentia Avenue. Additional special -status species which have been identified for the Newport Beach Quadrangle, include the California least tern (Sterna antillarum browni), western snowy plover (Charadius alexandrinus nivoszis), California black rail (Laterallus jamaicensis coturniculus), Belding's savannah sparrow (Passerculus sandwichensis beldingi), light-footed clapper rail (Rallus longirostris levipes), California brackishwater snail (Tryonia imitator) tiger beetle (Cicindela gabbii), and Monarch butterfly (Danaus plexippus). None of the above mentioned sensitive species occur on site due to a lack of suitable habitat. Burrowing Owl Surveys The western burrowing owl was not identified during focused surveys, nor was physical evidence (including cast pellets, prey remains, or excrement) detected within the survey area including at the pre -identified burrowing owl location (Exhibit 3). During the nesting season, burrowing owls will line their nest with shredded dried feces (generally that of coyote) and will replace it often. From previous experience with occupied burrowing owl sites, nesting status can be determined if the presence of discarded nest lining is present at the entrance of the burrow, in addition to cast pellets and whitewash. Because surveys were conducted near the end of the burrowing owl nesting season, if burrowing owls had nested, evidence of their nesting would have been detected. Therefore, it is the biologists' opinion that the area surveyed is "occupied" by a wintering owl. only and does presently support a nesting pair on site. According to the "Burrowing owl survey protocol and mitigation guidelines" prepared by the California Burrowing Owl Consortium (1993), a site should be assumed "occupied" if at least one burrowing owl has been observed occupying a burrow within the last three years (Rich 1984). Although the burrowing owl(s) was not observed during the focused burrowing owl surveys (conducted August 12-15, 2002), evidence of their occupation within the last three years is established, based on visual observation of one burrowing owl in February 2002 by a CDFG biologist. IV. PROJECT IMPACTS AND MITIGATION Native Grassland The proposed railroad re -alignment would impact up to 0.05 acre of native grassland, supporting purple needle grass (Nassella pulchra). Impacts to 0.05 acre of native grassland will Claire L. Flynn City of Costa Mesa September 12, 2002 Page 10 be mitigated at a 2:1 ratio through the creation of native grassland habitat within portions of Fairview Park to be restored as a component of implementation of the Fairview Park Master Plan. Vernal Pools Based on the proposed railroad re -alignment, the project would not result in direct or indirect impacts to any of the vernal pools identified. Western Spade -foot Toad Based on the proposed railroad re -alignment, the project would not impact any western spade - foot toads that may potentially occur on site, because the vernal pools identified on site will not be impacted. San Diego Fairy Shrimp Based on the proposed railroad re -alignment, the project would not impact any San Diego fairy shrimp that may potentially occur on site, because the vernal pools identified on site will not be impacted. California Gnatcatcher Based on the proposed railroad re -alignment, the project would not impact the California gnatcatcher as suitable habitat for this species does not occur within the subject site Nesting Birds Based on the proposed railroad re -alignment, the project could potentially impact nesting birds that may be present at time of the proposed activity. Western Burrowing Owl Expansion of the Model Railroad would not measurably change the amount of foraging habitat for wintering burrowing owls nor would the expansion directly affect the burrows identified as occupied. There would therefore be no direct impacts to wintering (or year-round resident) burrowing owls on the site. Claire L. Flynn City of Costa Mesa September 12, 2002 Page 11 Because the Model Railroad Facility at Fairview Park is already an existing use/condition, and is operated every third Saturday and Sunday of the month for approximately 5 % hours a day, it can be inferred that the wintering owl observed on site in February of 2002 was not affected by the monthly disturbance. Because California ground squirrel burrows are abundant throughout the property, if the infrequent activity of the train disturbed the burrowing owl, it is likely the burrowing owl would have relocated as suitable habitat for this species occurs elsewhere on site. In addition, based on the biologists experience of a nesting pair of burrowing owls near Murrieta earlier this year, which located their nest approximately five -feet from a public side- walk and main thoroughfare where decibel levels often exceed 80 decibels, it is unlikely that minor re -alignment of the railroad tracks from their current location, would cause indirect impacts associated with noise or movement of the train. If impacts to the wintering burrowing owl were to occur, it most likely would be a result of the construction activity associated with re -alignment of the railroad tracks, which would be a one- time temporary impact to the wintering owl. The proposed re -alignment of the track itself is generally approximately only 15 to 20 feet further .from the existing track location in the immediate vicinity of the burrowing owl location. The proposed location of the track in the biologists' opinion does not constitute a significant impact to the burrowing owl for the reasons mentioned above. V. RECOMMENDATIONS A rtiva NPctc If the proposed re -alignment is scheduled to take place during the nesting season for migratory birds (March 15 -August 15), it is recommended that a qualified biologist survey areas to be impacted no more than three days prior to the start of work. The project applicant should have a qualified biologist survey the project site for the presence of any occupied nests within the immediate vicinity of the proposed re -alignment. If active nests of migratory birds are located, measures to ensure protection of the nesting migratory bird (including avoidance of the nest or a temporary work stoppage) will be determined by the monitoring biologist and will depend on factors such as the bird species and the construction schedule. The biologist, if required, shall determine construction buffer zones for active nests. VPrnni Pnnlc Vernal Pool A is located immediately inside of the existing railroad track to be re -aligned. To insure that the vernal pool and its watershed is not impacted by the proposed activity, it is Claire L. Flynn City of Costa Mesa September 12, 2002 Page 12 recommended that no large equipment be operated in the vicinity of the vernal,pool and that the section of track adjacent to the pool be re -located by hand. If necessary, a biological monitor should be present to insure no impacts to the vernal pool. Also, temporary fencing or rope with T -bar could be installed to limit potential impacts to the vernal pool basin. Native Grassland The proposed 2:1 mitigation for the 0.05 acre of impacted native grassland, to be implemented as a component of the Fairview Park Master Plan is adequate compensation for the impacts. Therefore, no additional recommendations are necessary. Burrowing Owls To ensure that the burrowing owl and its occupied habitat is not impacted by the proposed activity, it is recommended the proposed construction activities be conducted outside of the burrowing owl wintering season which can begin in mid- to late -November and extend into. the first or second week of March. If it is necessary to conduct the activities during this period, it is recommended that a pre - construction survey be conducted weekly beginning in the first week of November to determine if'a burrowing owl has arrived at the site. As long as the site has not become occupied, no additional measures would be necessary. If a burrowing owl occupies the site, it is recommended that no large equipment be operated in the vicinity of the occupied habitat and that the section of track adjacent the occupied habitat be re -located by hand. A biological monitor will flag the occupied habitat that should be fenced or marked with yellow rope and T -bar to limit incursions into occupied areas. As long as work is occurring within 300 feet of the occupied burrows, the biologist should conduct daily monitoring visits to ensure that encroachment into the area does not occur. These measures should be sufficient to avoid temporary indirect impacts to the burrowing owl. Western Spade -Foot Toad — Potential western spade -foot toad habitat occurs within the three vernal pools discussed in this report. To ensure that the vernal pool and potentially the western spade -foot toad is not impacted by the proposed activity, it is recommended that no large equipment be operated in the vicinity of the vernal pool and that the section of track adjacent to the pool be,re-located by hand. If necessary, a biological monitor should be present to insure no impacts to the vernal pool. Also, temporary fencing or rope with T -bar could be installed to limit potential impacts to the vernal pool basin. Claire L. Flynn City of Costa Mesa September 12, 2002 Page 13 San Diego Fairy Shrimp - Potential San Diego fairy shrimp habitat occurs within the three vernal pools discussed in this report. To insure that this habitat and potentially the San Diego fairy shrimp is not impacted by the proposed activity, it is recommended that no large equipment be operated in the vicinity of the vernal pools and that the section of track adjacent to vernal pool A be re -located by hand. If necessary, a biological monitor should be present to insure no impacts to the vernal pool. If you have any questions regarding this letter report, please call me at (949) 837-0404.
