VI. Utilities and Service Systems:

The Discussion for Sub -section (b) notes that the potential need for new or expanded wastewater treatment facilities is "potentially significant" and states that this need will be analyzed in the DEIR. It is assumed that the analysis will lead to mitigation measures to reduce potential impact to "Less Than Significant With Mitigation Incorporated." As stated previously, this designation appears to be premature. The NOP should designate this potential impact as "potentially significant" until the DEIR analysis is completed.

Sub -section (d) refers to availability of water supplies to support the proposed Project and should be designated as "potentially significant" until the EIR analysis shows otherwise. The DEIR analysis should consider how the proposed Project could be designed to make maximum use of recycled water to minimize the need for fresh water.

Sub -sections (e) and (f), which address wastewater generation and increased general of solid waste, should also be designated as "potentially significant" until the EIR analysis proves otherwise.

C. Conclusion:

Thank you for the opportunity to comment on this important Project. We hope that these comments will assist the City in the DEIR and the final Project.

2.) Draft Circulation Element 01232-28b.doc
Dear Mr. Ramirez:

The following eight points need to be addressed in the EIR prepared on the basis of Ref. 1. NOR Importantly the EIR must assess its proposed mitigation measures for the traffic growth created by the General Plan Update and its handling by the city along with traffic growth permitted under the current General Plan and planned huge traffic growth in the Irvine Business Complex.

As a baseline, the latest city traffic studies currently show that six intersections in the city are unsatisfactory i.e. operate at LOS E or above. This means that the city does not have the funding to correct current discrepancies in its Circulation System. (1.) The NOP projects major and expensive intersection and in some cases roadway improvements that are totally unfunded. The proposed improvements, whose funding is highly questionable as further described below, still leave four intersections remaining that are not operating at a satisfactory level (LOS D or below). These four intersections are shown in the Ref.2.) Traffic Study to operate at LOS E and above and therefore are in violation of the state requirement that the Land Use Element match the capacity of the Circulation Element.

An even larger problem presents itself in the proposed mitigation of the 13 intersections and/or arterials named in the NOP. Newport Beach City Law (The Traffic Phasing Ordinance) was changed to meet constitutional rulings that developments can be charged only for their proportional share of the cost of mitigating unsatisfactory traffic created by their project.

While many of the developments authorized by the General Plan Update will be built within a few years of its approval, it will take many years for additional developments to be built that will furnish sufficient additional funding to actually enlarge an intersection and/or roadway. It will also be that in many cases very close to a full additional load will be placed upon an intersection but the funds to complete the improvements will be lacking. During that interim period, that is indeterminate in length, the roadways will be more congested than would bee indicated by the false assumption that all the intersections were improved as of the date of the EIR study.

(2.) A further problem presents itself in the city's proposed plan to enlarge 13 intersections. Most of these proposed improvements require widening of the intersection to add more turn lanes or through lanes. This widening will require expensive condemnation of land. Where is the funding for these actions plus noise abatement walls and the actual construction of the additional lanes? (3.) Therefore, the EIR must examine a phased implementation of Circulation system improvements and the resultant traffic congestion until the time in the future when the city will be able to accumulate sufficient funding to actually improve all intersections. A summary of the proposed thirteen intersection and arterial street improvement costs is needed along with a timeline display of when the improvements will actually be made along with the projected construction rate of the proposed developments.
(4.) Also of great concern, the widening of intersections will place traffic closer to residential areas. Noise mitigation that is acceptable to the homeowners is also required. (5.) Has the traffic generated by the huge residential dwelling complex in the City of Irvine on Jamboree Road near Campus Drive been included in the traffic calculations? (6.) The City of Irvine has changed its General Plan and completed an EIR to permit the construction of approximately 10,000 more dwelling units in the Irvine Business Complex. The Circulation system traffic numbers and subsequent proposed mitigation must include provisions for a good portion of this excess traffic that will unquestionably use Newport Streets in the Airport Area, and Bristol, Campus, McArthur and Jamboree Roads. While the city of Newport Beach has announced it is looking into measures to block or mitigate this City of Irvine plan at this late date, the Newport EIR must contain provisions for this traffic even if only as an alternate case.
(7.) The intersection of Goldenrod and PCH has been shown in traffic studies conducted over the last five years to operate at unsatisfactory levels. Recently, a statement was issued that this intersection would operate at LOS F because it couldn't be mitigated. An explanation is needed as to how the traffic in this intersection was claimed to have been recalculated and the problem eliminated.
(8.) The impacts of summer traffic need to be studied and mitigation measures proposed. In particular, given the proposed 245 units of housing plus mixed use commercial projected for the Mariner's Mile section of Pacific Coast Highway, what will be the summer season impacts on Pacific Coast Highway, Newport Blvd and impacted arterials between the freeways and beach access locations. Given the 3300 housing units proposed for the airport area, how will summer traffic mix with those units plus the 10,000 additional city of Irvine Dwelling Units? Thank you,
Greenlight

RE: Notice of PreparationllS — City of Newport Reach General Plain Update Dear Mr. Ramirez:

The City of Irvine has received the Notice of Preparation for the above project. Based on its review, the City of Irvine has the fallowing comments:

1. Land Use Chan es in the John Wayne Airport Subarea. Please provide specific information on the location of proposed land use intensity changes that increase development potential in the John Wayne Airport; area, as well as witywide, Table 3 of the NOP identifies an increase of 4,300 additional multi faultily units over the existing General Plan. In particular, please identify each location where the increase is proposed, including surface parking lots, Provide information an the existing land use designation for each site and the current development potential as well as the proposed land use designation and site speo'rtic acreages. A comparison of each site's existing General Plan land use designation and its proposed General Plan designation will provide the City of Irvine with the opportunity to determine if a substantial environmental impact will occur as a result of the proposed General Plan Update.

2. Given the proposed General Plan intensity increases in the John Wayne Airport Business subarea, the traffic analysis should include arterials and intersections within the City of Irvine bounded'by Main Street to the north, Red Hill Avenue to the west and Harvard Avenue/University Drive to the east. Depending on where the proposed intensification is within the subarea,, the traffic analysis study area should be expanded to the north and east accordingly. Additionally, the study area should be expanded if impacts are identified along these boundary arterials and intersections.

3. The traffic analysis should analyze the cumulative impacts of the significant projects currently under review within the City of Irvine. Contact City staff for an active list of projects to include based on the ctit-off date of the traffic analysis. nomiTCf1 nK1 DCI'Vrll cr) DADCD

subject. Notice of Preparation/Initial Study for City ofNewport Beach General flan Update Deaf' Mr. lea nirez:

John Wayne Airport, Orange County (SNA) ("SWA" or "the Airport") appreciates this opportunity to comment on the Notice of Preparation/Iaitial Study ("NOP/IS ") for the Environmental Impact Report (" EIR") that will be prepared for the City of Newport Beach's ("City") General Plan Update project. We understand from the NOP/IS that the General Plan Update includes a specific "Sohn Wayne Airport Area" special study subarea which will allow for the development of new residential neighborhoods as replacement of existing and allowed future uses. We would appreciate an opportunity to review the General Pan Update document when it can be made available to us.

GENERAL CO1V, MPNTS
In the NOP/Is, references are made to policies that "establish criteria for the development of cohesive residential neighborhoods oriented around neighborhood parks and local -serving convenience commercial facilities and interconnected by a network of pedestrian -oriented streets" within the subarea designated as "lohn Wayne Airport: Area." The Airport requests that the City address the impacts of any new residential development policies considering JWA's existing and future airport operations and given the proximity of this subarea to the Airport. General flan policies and/or EIR mitigation measures should be considered which incorporate specific information regarding the following requirements: (1) sound attenuation; (2) height limitations; (3) density/intensity limitations; (4) notification requirements; (5) avigation easements; (6) obstruction lighting and marking requirements; and (7) compliance with all Federal Aviation Administration ("FAA"), California Department of Transportation, Division of Aeronautics ("Caltrans"), and Airport Land Use Commission ("ALUC") requirements,
In addition, the Airport has a number of more specific comments. that we would like the City to consider as it moves forward on the General Plan. Update, as provided below.

SPECIFIC COMMENTS

GENERAL PLAN POLICIES AND EIR MITIGATION MEASURE,,S
The following restrictions should be included as General Plan policies and EIR mitigation, measures for all residential development' within the John Wayne Airport Area residential development.

I, Sound Attenuation: Include General plan sound attenuation policies and EIR mitigation measures for adl John Wayne Airport Area residential development: in order to minimize the noise impacts on the residences from present and projected future noise levels, including roadway, aircraft, helicopter, railroad and other noise sources. The sound attenuation requirements should, at a minimum, meet all current City interior and exterior noise standards.

2. Avigation Easement: Include General Plan policies and EIR mitigation measures requiring all John Wayne .Airport Area residential development to record an avigation easement in the chain of title of each residential dwelling unit for noise and related aviation impacts in favor of the County of Orange, the airport proprietor of SWA, prior to issuance of building pennit .

The avigation easement should be in a form consistent with current. Airport requirements. (This avigation easement is separate from and in addition to the "Avigation Easement for Orange County Airport" recordeCd March 17,1964 in book 6965, page 721, which represents a separate John Wayne Airport "ownership" avigation easement already existing over pordons of the City of Newport Beach.)

3. sleight Limitations: Include General Plan policies and EIS, mitigation measures addressing height limitations on all John Wayne Airport Area residential development to limit the height pf any permanent or temporary structure, to a. height under 203.68 feet Above Mean Sea Level ("AMSL") reference National Geodetic Vertical Datum of 1929 (NG VD 29) consistent with current Orange County Surveyor Adjustment Datum.

4. Obstruction Lighting and Marking: Include General Ilan policies and EIR mitigation measures addressing lighting and marking on all John Wayne Airport Area residential development to comply with the conditions and recommendations by t1w FAA with respect to obstruction lighting and/or marking consistent with the criteria provided in FAA Advisory Circulars 70/7460-1 and 70/7460-1K,
S. Disclosure of JW.A .Aroximity: Include General flan policies and EIR mitigation measures for occupancy disclosure to be provided in future sales literature and saxes/rental/lease agreements for the residential developments stating that the property is located in the vicinity of JWA.

6. -Veed Disclosure Notice; Include General Plan policies and EIR mitigation measures for deed discloswe notification on all John Wayne Airport Area residential development units which require a "Deed Disclosure Notice" 4f the avigation easement. This disclosure notice must be submitted to the City and signed as a part of each sales/rental/lease agreement,

7. Signage: Include Qeneral Plan policies and EIR mitigation measures fox signage on all holm Wayne Airport Area parks and recreational development whieh requires every local park, recreational area, and private recreational facility to place appropriate signage indicating the presence of operating aircraft.

8. Density and Intensity Limitations: Include General Plan policies and EIR mitigation measures in order to minimize the safety impacts on the ,residences from aircraft operations.

The safety measures should establish appropriate criteria limiting the maximum number of dwellings or people in areas close to the airport. The density and intensity limitations should be consistent with those provided by the Airport Environs Land Use Plan for the Airport.

MR ANALYSIs
T11e land use designation, changes being proposed for the John Wayne Airport Area are, in certain cases, significant departures fxQm the land uses currently designated for the Area. The current nonresidential designations permit uses which are generally compatible with the nearby JWA use. In contrast, the proposed residential uses are generally not compatible with a. nearby airport. We believe that the EIR needs to include a complete analysis of envirorrrnental impacts ofthe proposal to amend the General Plan to provide additional residential development in pxQximity of the Airport.

Consistent with our understanding Of the City's goals of developing a strategy or plan for residential development in the John Wayne Airport Area, we have provided below specific comments related to the proposed residential, policies for the area and potential impacts and mitigation measures that should be addressed in the EIR.

1. General Plan Policies for Residential Development in the General Plan John Wayne Airport Area Subarea Should Include Adequately Protecting Future Residential Development From Operations at JWA.

Q;ne of the goals of developing a strategy Or plan for residential development in the City's JWA subaarea should be to adequately protect future residential development from current and projected future aircraft operations at JWA. Specifically, one of the goals should be to ensure that any future residential projects are well planned and provided with the type of protections (4e,, sound attenpation, height limitations, density/intensity limitations, and

FEB.27.2006 4:25PM AIRPORT LAND USE COMMISSION NO.292 P.5i10 Gregg Ramirez
City of Newport Beach
FeWary 27, 2006

adequate notice) needed. These protections should include, all of the items specified previously in this letter and discussed in more detail below.

2. The General Plan Should Include Specific Development Policies for the John Wayne Airport Area Related to Operations at ,TWA.

The following issues should be addressed in the EIR related to any residential development that is proposed for the John Mayne Airport Area subarea:
a. Sound attenuation development standards fpr all residential development. b. Avigation easement requirements for all residential development. c, Height limitation development standards for all residential development, d, Density/intensity limitation development standards for all residential development. e, Obstruction lighting and marking development standards for all residential development.
i Disclosure of JWA proximity development requirements. g. Deed disclosure development requirements,
h, Signage development requirements for public parks and recreational areas.

3. General flan and EIR Maps Depicting the John Wayne Airport Area Should Include JWA's 75, 70, 65 and 60 dB CnL Noise Contour and the Airport's Runway Protection Zones.

A map should be included in the EIR depicting the 75, 70, 65 and 60 decibels ("413") Community Noise Equivalent Level ("CNEL") noise contours for JWA, In addition, Lm,x(10) single event noise levels should be determined through field measurements collected during an appropriate time period of representative aircraft operations and included in the EIIt. Only in t11is way can, the information provide a true and complete picture of the noise eavironrneat resulting from airport operations that would result if a residential project is built at a given location within the JWA planning subarea, information regarding the number of flights that are projected to take off and land at JWA should also be provided.

Finally, the map should include the current boundaries of the Airport's Runway Protection

Zones. The Airport is available tQ worlc with the City on these issues and to provide any necessary information.

4. The Airport Land Use Commission Compatibility Policies Should be Addressed in the General Plan and EIR.

The General Plan and EIR. should include a detailed discussion regarding Airport Land Use ComrnisSion (" ALUC") land use compatibility policies and whether the proposed SWA planning subarea is consistent with these pglicies, Although the City is required to submit the proposed General Plan Update project to the ALUC for an independent consistency determination with the JWA Airport Environs Land Use Plan, the General Plan and EIR should provide a discussion of the ALUC policies and the extent to which. the City believes that the General Plan Update is consistent with these policies.

5. The General PIann Update and EIR Should Address Policies and Mitigations for Residential Land Use in the ,TWA Planning Subarea including Sound Attenuatign, Density/Intensity Limitations, Avigation Easement, Height Limitations, Obstruction Lighting and Marking, Oacupaney and Deed Disclosure, and Signage.

Because the location of the subarea designated "John Wayne Airport Area" is in close proximity to JWA, the policies and mitigation measures used for residential development should be tailored toward minimizing incompatibilities between any new residential development and the ongoing aperatiom at JWA, to the extent possible, We believe that using the following set of guidelines will help create the type of neighborhood that will be successful, desirable and sustainable in the long tent.

A. SoundAtteaua lion
Portions of the General Plan/John Wayne Airport Area will be impacted by current and projected future aircraft noise levels. Single event noise level standards that apply to the interior of residential units located within the 60 d13 CNEL noise contour should be incorporated into the General Plan policies and EIR mitigation, measures as a standard for future residential development. In addition, the mitigation measures should provide detail regarding the type of acoustical testing that will be required to ensure that the inte.rinr noise level criteria has been met.

B. Avigation Easements
The General Plan and. EIR should include policies and mitigation reasures that require all John Wayne Airport Area residential development to record an avigation

FEB.27.2006 4:25PM AIRPORT LAND USE COMMISSION NO.292 P.7i10 Gregg Ramirez
City of Newport Beach
February 27, 2006

easement for noise and related aviation impacts in favor of the County of Orange, the airport proprietor of .TWA, prior to issuance of building permits. The avigation easement should be in a form consistent with current Airport requirements.

C. Height Limitations
The STkTE AERONAUTICS ACT (PUBLIC UTILITIES CODE §§21001, et seq.) provides for the right of flight over private property, unless conducted in a dangerous manner or at altitudes below those prescribed by federal authority. M.UTIL.CoDE §21403(a). No use shall be made of airspace above a property wl-dch would interfere with the right of flight, including established approaches to a runway, Pua.UTrL,CoDE §21402. Specifically, the guidelines of FEDERAL AVIATIOX RErjULATToN (FAR) Part 77, Objects Affecting Navigable A irspace (14 C.F.R. §§77, et seq.), establishes imagiw.ty surfaces for airports and runways as a means to identify objects that are obstructions to air navigation. Each surface is defined as a slope ratio or at a certain altitude above the airport elevation.

The FAA uses PAR Part 77 obstruction standards as elevations above which structures may constitute a safety problem. The regulations require that anyone proposing to construct an object which could affect the navigable airspace around an airport submit information about the proposed construction to the FAA. The FAA then conducts an aeronautical study, the outcome of which is a determination as to whether the object would be a potential hazard to air navigation. If the proposed object is determined to pose a hazard, the FAA may object to its construction and issue a detennination of a hazard to air navigation, examine possible revisions of the proposal to eliminate the problem, -require that the project be appropriately marked and lighted as an airspace obmotion, and/or initiate changes to the aircraft flight procedures for the airport so as to account for the object.

The dimensions of the imaginary surfaces Vary depending on the type of approach to a particular runway based on the ultimate dimensions shown on the airport layout plan. Where imaginary surfaces overlap, the lowest surface is used to determine whether or not an object would be an obstruction to air navigation. The FAR Part 77 horizontal surfaces limit the height of structures on a project site to an elevation of 203.68 feet above mean sea level (AMSL) reference National Geodetic Vertical I)aturn of 1929 (NOWD 29) consistent with current Orange County Surveyor Adjustment Datum,
in addition to the FAR Part 77 requirements, the County of Orange imposes specific height restrictions on buildings and other structures in the environs of TWA.

City of Newport Beach
February 27, 2006

Specifically, on March 17, 1964, the Orange County Board of Supervisors recorded an "Avigation Easement for Orange County Airport, In Boole 6965, rage 721" covering approximately 18,500 acres around the airport. The avigation easement specifies: "the air avigation easement does not allow buildings or structures to project into the air space above the surfaces shown and defined, and allows aircraft using the Orange County Airport to operate above these surfaces." In the four decades history of the Avigation Easement the Board has, on a case -by -case basis and for substantial financial remuneration, allowed particular non-residential high, -rise buildings to be constructed above, and therefore, into the County s avigation easement elevation of 203.68 feet AMSh in the "horizontal surfaces" area However, also during this tune period, the Board has maintained a. consistent policy of not permitting any residential project to be constructed within the horizontal surfaces. In maintaining this strict standard, the Board has focused on the safety of, and environmental impact to, high- rise residential buildings near JWA that result froin aircraft operations.

The General Plan Update/John Wayne Airport Area boundary falls within the approximate 10,000-foot radius "horizontal surface" area near JWA. The General Plaa and EIR should therefore include a discussion of the County's avigation easement surrounding JWA and the FAR Part 77 requirements, In addition, the General Plan and. EIR should include policies and mitigation measures that restrict the height of buildings consistent with Part 77 and the Counnty's avigation easement height limitations.

D. Obstruction 4igliting and Marking
In addition to the PAR, Part 77 height requirements, the FAA also specifies lighting and marking requirements for structures and related land uses in order to minimize air hazards in the areas surrounding airports. It is important for the City of Newport Beach to impose consistent lighting and marking development standards on all John Wayne Airport Area residential development which requires all development to comply with the conditions and recommendations by the FAA with respect to obstruction lighting and/or marking consistent with the criteria provided in FAA Advisory Circulars 70/7460-1 and 70/7460-IK.

E, DiscloSare of JWA Proximity
California Civil Code sections 1103.4(c)(1) and 1353(a), and California Business and Professions Code sections 11010(a) and 11010(b)(12)(13) require the disclosure of airport noise, vibration, mid odors in expert -prepared natural hazard disclosure reports for residential property sales or lease. Specifically, if the property is located

FEB.27.2005 4=26PM AIRPORT LAND USE COMMISSION NO.292 P.9f10 Gregg RanireZ
City of Newport Beach
February 27, 2006

within the airport i4u,ence area of JWA, the report must contain the follOwing statement:
"NOTICE OF AIRPORT IN VICWITY
This property is presently located in the vicinity of an airport, within what is known as an airport influence area. For that reason, the property may be subject to some of the annoyances or inconveniences associated with proximity to airport operations (for example: noise, vibration or odors).

Individual sensitivities to those annoyances can varyfrom person to person.

You may wish to consider what airport annoyances, if any, are associated with the property before you complete your purchase and determine whether they are acceptable to yore."
The General Play policies and EIR mitigation measures for residential development in. the JWA planning subarea should include this Notice of Airport in Vicinity notification requirement.

F. Deed Disclosure Notice
Ea addition to the disclosure of JWA pro�c ty notice requirements discussed above, General flan policies and EIR mitigation measures should specify that deed disclosure notice requirements be imposed on all John Wayne .Airport Area residential development, A "Deed Disclosure Notice" of the avigation easement should be submitted to the City and signed as a part of each sales/rental/lease agreement.

G. Signage
It is important that the General Plan and EIR recognize the noise impacts associated with outdoor recreational use (as opposed to indoor residential use). In this regard, the General plan and EIR. slxould include policies and mitigation measures for signage on all John Wayne Airport Area park and recreational development indicating the presence of operating aircraft.

I . Detash,)&T atensity Limitations
It is important that the General Flan and EIR recognize the safety impacts associated with development in proximity to the Airport. The overall objective of safety compatibility criteria is to minimize the risks associated with potential

aircraft accidents. There are two components to this objective, however. The most fundamental safety compatibility component is to provide for the safety of people and property on the ground in the event of an aircraft accident near an airport, The other important component is to enhance the chances of survival of the occupants of an aircraft involved in an accident which takes place beyond the immediate runway enviromnent. Specific compatibility strategies must consider both components of the safety compatibility objective. The primary strategy is to limit the use (the number of people concentrated on the site) in locations most susceptible to an off -airport aircraft accident. The most direct method of reducing the potential severity of an aircraft accident is by the establishment of criteria limiting the maximum number of dwellings or people in areas close to the airport.

The General flan and EIR should include policies and mitigation measures that recognize these compatibility strategies related to safety concerns.

We appreciate your efforts to address the issues contained in this letter and look forward to continuing to work with you in connection witl-L the preparation and approval of the City of Newport Beach General Plan Update and EIR in order to ensure that the General Plan and EIR provide adequate means for implementing policies and enforcing EIR mitigation measures, to the extent possible, to minimize the impact of airport operations on residential development within the General Plan. uea near IWA.

SUBJECT: NEWPORT BEACH GENERAL PLAN UPDATE
Dear Mr. Ramirez:

AM FEB 2 i 2006 PM
19110 t11112 `1,213141516
On behalf of the property owners of the Newport Banning Ranch we appreciate the opportunity to offer comments to your Notice of Preparation ("NOP") of a Draft Environmental Impact Report in support of the City's General Plan Update. We have been participating in the General Plan Update through attendance at the various community workshops, committees and via testimony before the City Planning Commission and City Council.

Although some sentiment exists for acquisition of the entire Banning Ranch property for open space purposes, the property owners believe a high quality master planned re -development of the site holds the most promise. For many decades the Banning Ranch has been used for oil and gas production and these uses still encumber most of the site. In addition to land value, we believe the open space acquisition option in the City's General Plan needs to consider the significant additional costs associated with proper oil field closure and consolidation as well as the fiscal realities related to subsequent habitat restoration and long term maintenance obligations.

The owners have attempted to work with all interested parties on acceptable General Plan thresholds for the future use and/or development of the property. These thresholds for the property would allow for up to:
a) 1375 residential dwelling units,
b) 75,000 square feet of retail commercial uses,
c) a 75 room coastal inn, and
d) open space preservation and recreational uses.

In reviewing table 3 of the City's NOP document, we noticed an effort had been made to essentially allocate the proposed 1375 dwelling units as one-half multi -family and MP605502 - 1

one-half single family units. We expect the project to provide a range of residential housing types based on future planning and market studies and as such, would not want to be constrained by an artificial allocation at the present time. Table 3 also makes reference to up to 500 students as a proposed use. We assume this allocation is made in context of the property owned by the Newport -Mesa Unified School District. Although unknown at the present time, it is possible future discussion and planning with the school district could result in addressing school needs with offsite facilities. If that were the case, we would not want to create the burden of a future General Plan Amendment. We are not in a position to represent the views of the school district on this matter but would propose the 500 student reference to represent an "allowable but not mandatory" use for General Plan purposes. Finally, table 3 also shows what appears to be 60 acres of Park/Open Space. We acknowledge and support the City's desire to reflect adequate park and open space in a future re -use of our property but do not understand where the referenced acreage number came from and therefore are not in a position to offer our consent.

We anticipate the Banning Ranch will feature large areas devoted to natural open space preserves, trails and active recreation uses. The precise size and location of which will be determined through a collaborative planning process.

In closing, we look forward to continuing our efforts to work with the City and its residents on the General Plan Update.

Thank you for the opportunity to review and comment on the Notice of Preparation/Initial Study for and Environmental Impact Report (EIR) for the City of Newport Beach General Plan Update. The General Plan Update includes the existing City of Newport Beach boundaries and its sphere of influence.

Caltrans District 12 status is a reviewing agency on this project at this time and would like to work in active partnership with the local jurisdictions and the private sector to ensure that:

1. The General Plan states policies stressing Caltrans coordination and early involvement in project and program development.

2. The General Plan addresses the fact that Caltrans has regulatory authority over certain developments that directly or indirectly impact State Transportation facilities.

3. The General Plan, specifically the Transportation/ Circulation element takes the regional overview of the transportation issues, problems, and solutions in to consideration. Including language requiring the City to develop policies stressing coordination between the City and Caltrans early in the land use and transportation planning process.

4. Caltrans right of way and possible need for encroachment permits are identified.

If you have any questions or need to contact us, please do not hesitate to call Maryam Molavi at (949) 724-2267.

Description The General Plan Update defines comprehensive land use, noise, housing, circulation, and infrastructure, public service, resource conservation, and public safety policies for the entire City.

While policies regarding future land use and growth are addressed from a citywide perspective, the majority of land use changes are limited to nine primary tudy areas. Accordingly, the EIR will comprehensively address the impacts of all policies thoughout the City and, additionally, focus on those areas in which the most significant land use changes could occur.

We have determined that the proposed Plan is regionally significant per California Environmental Quality Act (CEQA) Guidelines (Section 15206). The project is a local General Plan Update. SCAG bases review of such plans on its adopted regional plans:

Destination 2030: 2004 Regional Transportation Plan (RTP) Regional Comprehensive Plan and Guide (RCPG) —1996 Version Compass Growth Vision
CEQA requires that EIRs discuss any inconsistencies between the proposed project and the applicable general plans and regional plans (Section 15125 [d]). Please state separately how the proposed plan will or will not support each regional plan. Please cite specific policies in the regional plans that the proposed plan supports. if there are inconsistencies, an explanation and rationalization for such inconsistencies should be provided. Visit www.Sca-q.ca.gov for downloadable versions of these documents.

SCAG a!sc offers the following, comments:

The Compass Growth Vision embraces strategic residential infill to achieve improved mobility, livability, prosperity, and sustainability. It appears that the proposed Newport Beach General Plan Update would encourage a better jobs -housing balance in existing employment centers. Please explain how the Newport Beach General Plan Update will or will not encourage such policies consistent with the Compass Growth Vision.

Please provide a minimum of 45 days for SCAG to review the EIR when this document is available. If you have any questions regarding the attached comments, please contact me at (213) 236-1851. Thank you.

Notice of Preparation of a Draft Environmental Impact Report for City of Newport Beach General Plan Update
The South Coast Air Quality Management District (SCAQMD) appreciates the opportunity to comment on the above -mentioned document. The SCAQMD's comments are recommendations regarding the analysis of potential air quality impacts from the proposed project that should be included in the Draft Environmental Impact Report (EIR). Please send the SCAQMD a copy of the Draft EIR upon its completion. In addition, please send with the Draft EIR all appendices or technical documents related to the air quality analysis and electronic versions of all air quality modeling and health risk assessment files.

Air Quality Analysis
The SCAQMD adopted its California Environmental Quality Act (CEQA) Air Quality Handbook in 1993 to assist other public agencies with the preparation of air quality analyses. The SCAQMD recommends that the Lead Agency use this Handbook as guidance when preparing its air quality analysis. Copies of the Handbook are available from the SCAQMD's Subscription Services Department by calling (909) 396-3720. Alternatively, 'lead agency may wish to consider using the California. Air Resources Board (CARE) approved URBEMIS 2002 Model.

This model is available on the SCAQMD Website at: www.agmd . og v/cega/models.html.

The Lead Agency should identify any potential adverse air quality impacts that could occur from all phases of the project and all air pollutant sources related to the project. Air quality impacts from both construction and operations should be calculated. Construction -related air quality impacts typically include, but are not limited to, emissions from the use of heavy-duty equipment from grading, earth-loading/unloading, paving, architectural coatings, off -road mobile sources (e.g., heavy-duty construction equipment) and on -road mobile sources (e.g., construction worker vehicle trips, material transport trips). Operation -related air quality impacts may include, but are not limited to, emissions from stationary sources (e.g., boilers), area sources (e.g., solvents and coatings), and vehicular trips (e.g., on- and off -road tailpipe emissions and entrained dust). Air quality impacts from indirect sources, that is, sources that generate or attract vehicular trips should be included in the analysis.

Consistent with the SCAQMD's environmental justice enhancement I-4, in October 2003, the SCAQMD Governing Board adopted a methodology for calculating localized air quality impacts and localized significance

Mr. Gregg B. Ramirez, Senior Planner -2- January 31, 2006 thresholds (LSTs). LST's can be used in addition to the recommended regional significance thresholds as a second indication of air quality impacts when preparing a CEQA document. Therefore, when preparing the air quality analysis for the proposed project, it is recommended that the lead agency perform a localized significance analysis by either using the LSTs developed by the SCAQMD or performing dispersion modeling as necessary. Guidance for performing a localized air quality analysis can be found at hiip:// www.aqmd.goy/ceq,a/handbook/LST/LST.html .

It is recommended that lead agencies for projects generating or attracting vehicular trips, especially heavy-duty diesel -fueled vehicles, perform a mobile source health risk assessment. Guidance for performing a mobile source health risk assessment ("Health Risk Assessment Guidance for Analyzing Cancer Risk from Mobile Source Diesel Idling Emissions for CEQA Air Quality Analysis") can be found on the SCAQMD's CEQA webpages at the following internet address: hiip:// www.gqmd.gov/ceqa/handbook/mobile toxic/mobile toxic html. An analysis of all toxic air contaminant impacts due to the decommissioning or use of equipment potentially generating such air pollutants should also be included.

Mitigation Measures
In the event that the project generates significant adverse air quality impacts, CEQA requires that all feasible mitigation measures that go beyond what is required by law be utilized during project construction and operation to minimize or eliminate significant adverse air quality impacts. To assist the Lead Agency with identifying possible mitigation measures for the project, please refer to Chapter 11 of the SCAQMD CEQA Air Quality Handbook for sample air quality mitigation measures. Additionally, SCAQMD's Rule 403 — Fugitive Dust, and the Implementation Handbook contain numerous measures for controlling construction -related emissions that should be considered for use as CEQA mitigation if not otherwise required. Other measures to reduce air quality impacts from land use projects can be found in the SCAQMD's Guidance Document for Addressing Air Quality Issues in General Plans and Local Planning. This document can be found at the following internet address:
http://www.aqmd.izoy/prdas/agizuide/agguide html. Pursuant to state CEQA Guidelines §15126.4 (a)(1)(D), any impacts resulting from mitigation measures must also be discussed.

Data Sources
SCAQMD rules and relevant air quality reports and data are available by calling the SCAQMD's Public Information Center at (909) 396-2039. Much of the information available through the Public Information Center is also available via the SCAQMD's World Wide Web Homepage ( http://www.agmd.gov) .

The SCAQMD is willing to work with the Lead Agency to ensure that project -related emissions are accurately identified, categorized, and evaluated. Please call Charles Blankson, Ph.D., Air Quality Specialist, CEQA Section, at (909) 396-3304 if you have any questions regarding this letter.

General Plan Update
Notice of Preparation/Initial Study
January 2006
By Fax- 949.644.3229
Dear Mr. Ramirez,
Thank you for the opportunity to comment on the NOP for the General Plan Update. I have the Following questions that should be addressed in the EIR:

1. Table 3. City of New -port Beach General Plan Update Existing and Proposed Land Use. Can you provide a total of how many residential units (du) will be added to the existing dwelling units under the Existing, Current OP and Proposed GP, and what the incremental changes are? For example, l now have to add the Existing NIFR and SFR to get 39,369 du, I have to add 29,504 NTR to 19,570 SFR to get 49,074 du under the Current GP, and l have to add Proposed MFR 34,303 plus 20,402 SFR to get 54,705 du under the Proposed General Plan.. Thus, the Proposed General Plan will have 15,336 more du than existin& and 5,631 du more than the Current CrP, and the Current GP over existing is 5,631. This is important for people to know how much the City will grow under the different SGenarlos.
2_ What is the growth in population who will occupy the dwelling units, and what is the per cent growth compared to the existing?

3. What is the number of people per household under the different categories of Existing, Current GP, and Proposed GP?

4. What percent growth in population will occur under the Current GP and the Proposed GP?

5. What is the number of park acreage required under the Quimby Act and will the proposed GP meet these requirements?

6, Table 4, Transportation improvements under Proposed General Platt Update.

There are 13 additional intersection improvements with project proposed. The EIR should identify what actions need to be taken at each of these locations. Will land need to be acquired to improve the intersections? If so, from whom and at what cost? If land is not acquired, how will the improvements be accomplished?

7. Will parking need to be removed from the sides of streets to accomplish widening of highways such as Coast Highway in Mariners Mile?
& Will land need to be acquired to widen streets? From whom? At what cost?

9. The EIR should examine eliminating alternatives that are not feasible, such as the 19'h St3reetBanning Bridge over the Santa Ana River. Both the cities of Huntington Beach and Costa Mesa are actively working to eliminate this bridge from the County Master Platt of Arterial Highways. What will happen to Newport Beach traffic circulation if this bridge is not built? The traffic alternatives should include this very possible scenario in the EIR. For example, the city of Costa Mesa has proposed a series of alternatives to mitigate for loss of the bridge. These alternatives can be obtained from the City Manager of Costa Mesa and should be included in the MR.

10. How will the recently announced decision of the city of Irvine to add an overlay of 10,000 dwelling units near John Wayne Ala port and Jamboree affect the circulation of Newport Beach and its capacity to handle the traffic from the development? See attached article from the Daily Pilot February 13, 2006 entitled: Housing flans worry Newport".

Thanks again for the opportunity to comment on the NOR Please put me on the mailing list for the EIR notices.

Sincerely,
Jan D. Vandersloot, MD

1. INTRODUCTION

SECTION 1.0 — INTRODUCTION
In August of 2003, EIP conducted reconnaissance -level biological surveys to supplement and refine information presented in the City of Newport Beach, California, Local Coastal Plan — Biological Appendix (Chambers Group and Coastal Resources Management, December 2002) and the City of Newport Beach, California, General Plan — Newport Beach Biological Resources (Chambers Group and Coastal Resources Management, January 2003). A detailed mapping and characterization of seven "Environmental Study Areas" (ESAs) — Banning Ranch, Buck Gully, Coastal Foredunes, MacArthur -San Miguel, Morning Canyon, Semeniuk Slough, and Spyglass Hill — was performed to provide further detail on the habitat composition and quality of each ESA, including the presence of potential waters/wetlands of the U.S., and the habitat's potential to support special -status species. From these data, a ranking system was developed, based on inherent habitat value, to evaluate the sensitivity of the ESAs to future development and guide the City with respect to biological resource permitting and ultimate development of the site(s)

1.1 PURPOSE OF STUDY
EIP Associates was contracted by the City of Newport Beach to supplement the findings presented in the City of Newport Beach, California, Local Coastal Plan — Biological Appendix (Chambers Group and Coastal Resources Management, December 2002) and the City of Newport Beach, California, General Plan — Newport Beach Biological Resources (Chambers Group and Coastal Resources Management, January 2003).

A Local Coastal Plan (LCP) is required under provisions of the California Coastal Act and is a basic planning tool used by local governments to guide development in the coastal zone, in partnership with the Coastal Commission. The Biological Appendix prepared for the City of Newport Beach, California, Local Coastal Plan in December 2002 included the delineation of 19 Environmentally Sensitive Habitat Areas (ESHAs), which are defined by the California Coastal Act as areas in which "plant or animal life or their habitats are either rare or are especially valuable because of their special role in an ecosystem that could easily be disturbed or degraded by human activities or development." The City of Newport Beach determined that the data used to delineate four of the ESHAs (Semeniuk Slough, Buck Gully, Morning Canyon, and Banning Ranch) was not detailed enough for the area to warrant designation as an ESHA. This document aims to provide the detail necessary to allow the Coastal Commission the ability to determine what areas, if any, within these four ESAs may be designated as ESHAs. An additional Non-ESHA Sensitive Habitat (p. 4-58 in City of Newport Beach, California, Local Coastal Plan) — the Coastal Foredunes — was also re-evaluated for the same purpose. This refinement of the habitat mapping of these areas will facilitate the decision -making process associated with any proposed development in these areas.

The Biological Resources section of the General Plan is intended to serve as an update to the City of Newport Beach, California, General Plan by identifying ESHAs in Newport Beach that warrant protection. The Biological Resources Report for the General Plan includes the delineation of nine areas previously designated P:\Projects-All Employees\10579-02 Newport Beach Bio\Addendum\addendum.doc 1 -1 December 8, 2003

1. Introduction
as ESHAs, two of which (MacArthur and San Miguel, and Spyglass Hill) the City concluded warranted additional analysis. As above, this document aims to provide the detail necessary to allow the City and Coastal Commission the ability to determine what areas, if any, within these two ESAs may be designated as ESHAs, according to criteria in the California Coastal Act. Refinements to maps based on this additional data will allow the City and potential developers to facilitate the decision -making process surrounding development proposed in these areas.

2. METHODOLOGY

SECTION 2.0 — METHODOLOGY

2.1 LITERATURE REVIEW/INFORMATION SEARCH
Information on occurrences of special -status species in the vicinity of the Study Area was gathered from the California Department of Fish and Game's (CDFG) Natural Diversity Data Base (CDFG, 2003) and the California Native Plant Society's (CNPS) Electronic Inventory of Rare and Endangered Vascular Plants of California (CNPS, 2003) for the quadrangles containing the Study Area (i.e. Newport Beach, Tustin, and Laguna Beach 7.5 minute quadrangles). The CNDDB and CNPS Electronic Inventory are historical observation records and do not constitute an exhaustive inventory of every resource.

Additional background on biological resources within the study area was derived from the Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland, 1986), the California Native Plant Society's Inventory of Rare and Endangered Plants of California (Tibor, Ed., 2001), The Jepson Manual — Higher Plants of California (Hickman, J.C., Ed., 1993), and the Draft Program Environmental Impact Report Newport Banning Ranch Local Coastal Program (PCR, 2000).

Lastly, EIP biologists reviewed the City of Newport Beach, California, Local Coastal Plan — Biological Appendix (Chambers Group and Coastal Resources Management, December, 2002) and the City of Newport Beach, California, General Plan — Newport Beach Biological Resources (Chambers Group and Coastal Resources Management, January, 2003) for relevant information on the specific ESAs covered in this report.

2.2 HABITAT VALUE RANKING
Basis of the Ranking System
For this report, EIP Associates has developed a system to rank specific areas within each of the respective ESAs based on a composite score of variables that collectively represent habitat quality. Habitats are attributed a low (3), moderate (2) or high (1) rank based on the number of positive or negative ecological attributes or functions (see below) in each area. In general, the more positive attributes or functions maintained by the habitat, the higher the rank, whereas areas with more negative attributes or functions are ranked lower. Moderate and highly ranked habitats are those more ecologically valuable and more likely to be adversely affected by development.

The following attributes were evaluated in ranking the various habitats within each ESA:
• Ability of the habitat to support special status species (recorded or potential) • Waters of the U.S. or jurisdictional wetlands
• DFG/CNDDB Sensitive Community (e.g. sage scrub, dune, etc.) • Degree of habitat integrity / connectivity
P:IProjects -All EmployeesM579-02 Newport Beach BioOddendumladdendum.doc2-2 December 8, 2003

2 — Methodology
While most of the above habitat characteristics are easily documentable from a variety of sources, habitat integrity/connectivity is a more subjective measure of biological value, which considers various attributes affecting a given habitat's quality in a particular geographic area. Attributes contributing to (or detracting from) habitat integrity include:
• Patch size and connectivity— Large "pieces" of habitat adjacent to or contiguous with similar or related habitats are particularly useful for more mobile species that rely on larger territories for food and cover.
• Presence of invasive / non-native species — Invasive/non-native species often provide poorer habitat for wildlife than native vegetation. Proliferation of exotic plant species alters ecosystem processes and threatens certain native species with extirpation.
• Disturbance — This includes disturbance due to human activities such as access (trails), dumping, vegetation removal, development, pollution, etc.
• Proximity to development — Habitat areas bordering development provide marginal habitat values to wildlife due to impacts from negative edge effects. This proximity presents the possibility of secondary effects to the habitat due to spillover or human intrusion. Deterioration of habitat results from intrusion of lighting, non-native invasive plant species, domestic animals, and human activity. • Fragmentation — The converse of "connectedness", habitat fragmentation is the result of development of large areas of undisturbed, contiguous habitat. The resulting breaking up of these areas into isolated, disjunct parcels can create barriers to migration, reduce wildlife food and water resources and generally compress territory size to reduce existing wildlife populations to nonviability.

Fragmentation increases negative edge effects, whereby the interior area of habitat is affected by the different conditions of the disturbance on its edges. The smaller a particular habitat is, the greater the proportion of its area which experiences the edge effect, and this can lead to dramatic changes in plant and animal communities. In general, loss of habitat produces a decline in species total population size, and fragmentation of habitat can isolate small sub -populations from each other. This process leads to conditions whereby animals and plant species are endangered by local, then more widespread, extinction.

2 — Methodology
Use of the Ranking System
The habitat ranking system can be used to direct development away from higher -value habitats or, at a minimum, indicate which areas will likely receive a greater level of resource agency scrutiny in the permitting process. It may also be used to guide mitigation.

Specific habitats within the respective ESAs are attributed a rank of 1 (high value) where proposed development would definitely require a resource permit, including, but not limited to:

1. U.S. Clean Water Act, Section 404 Permit through the U.S. Army Corps of Engineers -waters of the U.S. and associated wetlands;

2. U.S. Endangered Species Act, Section 7 or 10 consultation with the U.S. Fish and Wildlife Service — Listed threatened or endangered species or those proposed for listing;

3. California Fish & Game Code, Section 2081 Incidental Take Permit from the California Department of Fish and Game - Threatened or endangered species or those proposed for listing under the California Endangered Species Act;

4. California Fish & Game Code, Section 1601-1603 Streambed Alteration Agreement with the California Department of Fish and Game — waters of the State.

Habitats with a rank of 2 (moderate value) maintain significant characteristics to support the presence of special status plant and wildlife species. Proposed development in these areas will require additional field surveys to determine if resources are present, which would necessitate permitting activities.

Habitats with a rank 3 (low) are generally predominated by non-native species or otherwise exhibit a history of disturbance that make resource permitting a very unlikely requirement in these areas.

2.3 FIELD SURVEYS
Reconnaissance -level field surveys of were conducted on August 25, 26, and 27, 2003, by Ron Walker and Joshua Boldt of EIP Associates to examine each ESA in order to describe existing resources and to determine their distribution and relative abundance. Surveys focused on identification of areas exhibiting characteristics of natural or undisturbed habitats and areas that could potentially support special -status plant or wildlife species. Surveys of each ESA were conducted on foot and, in each, habitat types were identified and mapped and observed wildlife and plant species were recorded.

Surveys were conducted following a period of elevated precipitation for the Newport Beach area. While precipitation totals for the 2001-2002 wet season were well below average (3.55 in., average is 11.52 in.), those for the 2002-2003 wet season were slightly above average (14.73 in.) P:IProjects -All EmployeesM579-02 Newport Beach BioOddendumladdendum.doc2-4 December 8, 2003

2 — Methodology
( http://www.oc.ca.gov/prfd/envres/Rainfall/rainfalldata.asp) . Consequently, the composition of vegetation communities — in particular annual species and the extent of wetland areas —was likely to be representative of what is typically found in years of average precipitation.

2.4 MAP PREPARATION
Maps and data were created in GIS (Geographical Information Systems) format at a 1:2400 scale, or 1 inch = 200 feet, using ArcView 3.2a, using aerial photographs, coastal zone boundaries, ESA boundaries (Chambers, 2002, 2003) roads, parks, and parcels as base layers. Field observations and measurements were used to subdivide habitats within the existing ESA boundaries. Roads (either dirt or paved) that bisected a habitat were included within the boundaries of an ESA; whereas roads at the edge of an ESA were excluded. The subdivided ESAs were then ranked according to their relative value and resource permitting requirements.

Maps of all the ESAs were printed out, using the aerial photos as a base

2.5 ESA DEFINITION
When the City of Newport Beach drafted the first Local Coastal Program (LCP) Land Use Plan in the 1980s, the term "environmentally sensitive habitat area" was used to identify riparian areas, wetlands, intertidal areas, and other habitats that are considered to be environmentally sensitive. These environmentally sensitive habitat areas were described as being located on all or portions of twelve large areas. In 2002, a biological assessment study was conducted for use in updating the biological resource sections of the LCP Land Use Plan (Chambers Group and Coastal Resources Management, December, 2002) and the General Plan (Chambers Group and Coastal Resources Management, January, 2003). This biological assessment study carried over the term "environmentally sensitive habitat area" or "ESHA" to describe twenty-eight areas, including the twelve areas described in the existing LCP Land Use Plan.

The California Coastal Commission staff advised City staff that describing areas as ESHAs should be given careful consideration given the limitations on development within these areas as set forth in Section 30240(a) of the Coastal Act. Section 30240(a) requires the protection of environmentally sensitive habitat areas against any significant disruption of habitat values and limits uses to only those that are dependent on those resources. Consequently, subsequent drafts of the LCP Land Use Plan now identify these areas as "environmental study areas" (ESAs) to distinguish their geographic identification from the ESHAs that may be located within them. To avoid further confusion, this addendum to the 2002 biological assessment study has been prepared to more correctly identify the twenty-eight areas (nineteen in the coastal zone and nine outside of the coastal zone) as "environmental study areas."
ESAs are typically undeveloped areas supporting natural habitats that may be capable of supporting sensitive biological resources. An ESA may support species and habitats that are sensitive (e.g. wetlands) and rare P:IProjects -All EmployeesM579-02 Newport Beach BioOddendumladdendum.doc2-5 December 8, 2003

within the region or may function as a migration corridor for wildlife. ESAs may contain areas referred to as Environmentally Sensitive Habitat Areas (ESHAs), as defined under Section 30107.5 of the California Coastal Act. These are areas in which "plant or animal life or their habitats are either rare or are especially valuable because of their special nature or role in an ecosystem that could easily be disturbed or degraded by human activities or development". While an ESHA is, by Coastal Commission definition, a sensitive habitat, an ESA, as defined in this report, requires further study to determine if such a designation is appropriate or if a given area contains resources of particular value or concern.

SECTION 3.0 — BIOLOGICAL HABITATS

3.1 ENVIRONMENTAL STUDY AREAS
A variety of diverse, valuable, and sensitive habitats occur within the City of Newport Beach. Environmental Study Areas (ESAs) are those portions of the City that contain natural habitat. An ESA may contain areas that are considered ESHAs.

3.1.1 Semeniuk Slough (Oxbow Loop)

3.1.1.1 Description
Semeniuk Slough is a remnant channel of the Santa Ana River that historically drained into West Newport Bay and is still exposed to limited tidal influence through a tidal culvert connected between the Santa Ana River and the slough. The 76.74-acre site is bordered by the Newport Shores residential development to the south, the Santa Ana River to the west, and the Banning Ranch ESA to the north and east (Figures 2-3). The ESA is located on the USGS Newport Beach 7.5-minute topographic quadrangle. The Semeniuk Slough ESA includes the main slough channel immediately north of Newport Shores and the coastal salt marsh habitat to the north, including a narrow sliver of salt marsh habitat in the far north of the ESA, flanked by the Santa Ana River on the west and the Banning Ranch ESA on the east. Several smaller interconnected channels and inundated depressions are located throughout the salt marsh habitat.

Semeniuk Slough is predominantly an open -water estuary, with southern coastal salt marsh as the predominant fringing vegetation and chenopod scrub and ornamental vegetation as a less significant component of the ESA. Southern coastal salt marsh vegetation on -site is dominated by pickleweed (Salicornia virginica), alkali heath (Frankenia salina), California cord grass (Spartina foliosa), California sea -lavender (Limonium californicum), and salt grass (Distichlis spicata), with shore grass (Monanthohloe littoralis), fleshy jaumea (Jaumea carnosa), and saltwort (Batis maritima) as associated species. Sea -fig (Carpobrotus chilensis) has invaded some of the upland portions of the salt marsh habitat in areas adjacent to disturbance.

Other ornamental plant species found along the margin of the main slough channel, primarily in the eastern and southern section of the ESA near Newport Shores, include myoporum (Myoporum sp.), acacia (Acacia sp.), Mexican fan palm (Washingtonia robusta), pine (Pinus sp.), and eucalyptus (Eucalyptus sp.). An island in the southwest part of the ESA has been graded or otherwise disturbed in the recent past and the resulting plant community is less established than the surrounding salt marsh. This area is dominated by a mixture of salt marsh species, such as salt grass, heliotrope (Heliotropium curassavicum), and pickleweed, and upland ruderal species, such as burclover (Medicago sp.) and melilotus (Melilotus sp.) A small area of chenopod scrub occurs along the levee separating the Santa Ana River and the Semeniuk Slough ESA and is dominated by saltbush (Atriplex sp.)

Special -Status Species (Known Occurrences)
The following special -status species have recorded CNDDB occurrences or other known occurrences within or adjacent to the Semeniuk Slough ESA:
• Centromadia parryi ssp. australis (southern tarplant) (CNPS 1B) (CNDDB Occurrence #65): This occurrence of southern tarplant is from the "Newport Slough, south of the oil fields on the edge of the salt marsh and the access road." This is mapped at the western end of the access road north of the main slough channel in the Semeniuk Slough ESA. More than 100 plants were observed in 1998.

This population is presumed to still be present.
• Suaeda esteroa (Estuary seablite) (CNPS 1 B) (CNDDB Occurrence # 13): This occurrence of estuary seablite is from the "Newport Slough, south of the oil fields on the edge of the salt marsh and the access road." This is mapped along the margin of the access road north of the main slough channel, east of the southern tarplant occurrence, in the Semeniuk Slough ESA. This population is presumed to still be present.
• Passerculus sandwichensis beldingi (Belding's savannah sparrow) (CSC) (CNDDB Occurrence # 43):

The location of this occurrence of Belding's savannah sparrow is the "Santa Ana River mouth, Newport Slough area." The CNDDB maps this occurrence on the entire southwest portion of the ESA. 17 pairs were observed in 1996, and 36 pairs in 2001. This population is presumed to still be present. In addition, this species is known to breed in nearby areas including Upper Newport Bay and salt marsh habitat in Huntington Beach (MEC 1991).

P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.docM December8, 2003

3. Biological Habitats
• Aphanisma blitoides (aphanisma) (CNPS 1 B) (CNDDB Occurrence # 23): The information for this occurrence is from a 1932 herbarium collection from "Costa Mesa, along base of sea cliffs." It is mapped along the bluff separating Banning Ranch from Highway 1 and Semeniuk Slough. Although this population is presumed to still be present, it has not been observed since 1932. • The California least tern (Sterna antillarum) (FE, SE), which has a large nesting colony on the Huntington Beach side of the Santa Ana River mouth, forages occasionally in the slough channels (Atwood and Minsky 1983).
• Small numbers of western snowy plover (Charadrius alexandrinus nivosus) (FT, CSC) breed in the Huntington Beach least tern colony in some years (Gallagher 1997). Western snowy plovers are observed occasionally in Semeniuk Slough (MEC 1991).
• The California brackish water snail (Tryonia imitator) (FSC) has been collected in substantial numbers in the channels of Semeniuk Slough (MEC 1991).

Waters/Wetlands of the U.S.

The entire Semeniuk Slough ESA site is salt marsh/open estuary, except for small area of chenopod scrub along western border.

Integrity
The Semeniuk Slough ESA is a relatively large, uninterrupted coastal salt marsh. It is hydrologically and tidally connected to the Santa Ana River, which empties into the Pacific Ocean, and is also contiguous with the large Banning Ranch ESA on its northern and eastern borders. This provides wildlife with a relatively large, diverse area for foraging, shelter, and movement. The proximity to the Newport Shores residential development has introduced numerous ornamental and non-native species to the eastern perimeter of the site, and also allows use of the sloughs for recreational use. A few oil -well related structures are located in the southern part of the ESA, immediately north of the main slough channel. The land surrounding these structures has been cleared. Two roads bisect the ESA - one leading from the Santa Ana River levee to the Banning Ranch area, and the other leading to the oil well structures.

3.1.2 Buck Gully

3.1.2.1 Description
The Buck Gully ESA is a steep, open canyon extending 2.5 miles from Little Corona Beach to Newport Coast Drive in the San Joaquin Hills (Figures 9-12). The canyon is divided by the Coast Highway. The lower section extends from Little Corona Beach to the Coast Highway and the larger, upper section stretches from the Coast Highway to Newport Coast Drive. The 261.95-acre ESA is bordered by the Pacific Ocean and Little Corona Beach to the west, and residential and commercial development to the east, north, and south of the site. The Buck Gully site is located on the Laguna Beach 7.5-minute USGS topographic quadrangle.

The Buck Gully ESA is dominated by Diegan coastal sage scrub and southern mixed chaparral, with southern willow scrub, annual grassland, and coastal freshwater marsh occurring as smaller components of the community. Diegan coastal sage scrub and southern mixed chaparral encompass the majority of the gully - from the upper rims to the alluvial bottoms. A narrow ribbon of southern willow scrub riparian habitat is supported by an unnamed creek that flows along the canyon bottom the length of the gully. Patches of annual grassland occur throughout the chaparral and coastal sage scrub habitats and also in areas where native vegetation has been cleared for fire prevention.

The narrow, western reach of the canyon is largely encroached upon by the adjacent residential areas to the southeast and northwest. The upper slopes in this area of the canyon support a mix of disturbed southern mixed chaparral, a small patch of coastal sage scrub, and non-native ornamental vegetation originating from the surrounding homes. Typical chaparral species in this area include toyon (Heteromeles arbutifolia), laurel sumac (Malosma laurina), and ceanothus (Ceanothus sp.) Non-native and ornamental species include giant reed (Arundo donax), acacia, eucalyptus, myoporum, Mexican fan palm, Brazilian pepper tree (Schinus terebinthifolius), Peruvian pepper tree (Schinus molle), castor bean (Ricinus communis), tree tobacco (Nicotiana glauca), pampas grass (Cortaderia sp.), and fennel (Foeniculum vulgare). The canyon bottom in this area is dominated by riparian vegetation including willows (Salix spp.), blackberry (Rubus sp.), cattail (Typha sp.), and bulrush (Scirpus sp.). A small freshwater marsh comprised almost exclusively of cattail is situated at the mouth of the gully adjoining Little Corona Beach.

The central section of the canyon immediately northeast of the Coast Highway, while closely confined by residential development, contains fewer ornamental plant species than the coastal portion and supports southern mixed chaparral and southern willow scrub habitats with species compositions similar to the lower canyon. The chaparral in this area supports toyon, laurel sumac, ceanothus, chamise (Adenostoma fasciculatum), lemonadeberry (Rhus integrifolia), scrub oak (Quercus berberidifolia), southern honeysuckle P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-5 December8, 2003

3. Biological Habitats
(Lonicera subspicata), redberry (Rhamnus crocea), bush monkey flower (Mimulus aurantiacus), and sugar bush (Rhus ovata).

Approximately adjacent to the intersection of 5th Avenue and Poppy Avenue, the gully veers east and opens into a broader canyon. The southern slopes of the canyon in this area support dense stands of southern mixed chaparral, while the northern slopes support disturbed annual grassland, possibly established as chaparral and coastal sage scrub, but subsequently cleared for fire prevention by homeowners. At present, the annual grassland contains black mustard (Brassica nigra), tocalote (Centaurea melitensis), artichoke thistle (Cynara cardunculus), wild oats (Avena fatua), soft chess (Bromus hordeaceus), barley (Horedum sp.), ripgut brome (Bromus diandrus), and fennel. Diegan coastal sage scrub becomes more dominant as the canyon slopes on the upper portions of the canyon veer eastward. This community is composed of California sagebrush (Artemisia californica), California buckwheat (Eriogonum fasciculatum), white sage (Salvia apiana), prickly pear (Optunia sp.), coyote brush (Baccharis pilularis), blue elderberry (Sambucus mexicana), laurel sumac, lemonadeberry, and California bush sunflower (Encelia californica).

The canyon floor of Buck Gully supports a southern willow scrub community, dominated by willows and mule fat (Baccharis salicifolia), with occasional western sycamore (Platanus racemosa) and cottonwood (Populus fremontii). Associated plant species include cattail, blue elderberry, poison oak (Toxicodendron diversilobum), rush (Juncus spp.), and nutsedge (Cyperus sp.).

The upper canyon is broader than the lower canyon and is therefore less impacted by adjacent development.

Vegetation in this area is primarily Diegan coastal sage scrub and southern mixed chaparral, interrupted by occasional patches of annual grassland, and southern willow scrub associated with the creek at the canyon bottom.

The following special -status species have recorded CNDDB occurrences within the Buck Gully ESA:
• Euphorbia misera (cliff spurge) (CNPS 2) (CNDDB Occurrence # 21): The location for this occurrence is listed as "Corona del Mar State Beach" and consists of a total of three colonies at the following locations: "Inspiration Point south of Orchid Ave. at Ocean Blvd.; adjacent to Glen Dr./Beach Dr.; and south of Glen Dr." This first location is just north of the mouth of Buck Gully. A "Glen Dr." does not exist in Newport Beach, but the colonies associated with these locations are assumed to be in the general vicinity of the first colony. 60 plants were observed in 1989. This population is presumed to still be present.
• Dudleya multicaulis (many -stemmed dudleya) (CNPS 1 B) (CNDDB Occurrence # 94): The source for this occurrence is a 1908 herbarium collection from "Corona del Mar bluffs." This population has not been relocated and is believed to be no longer present. • Quercus dumosa (Nuttall's scrub oak) (CNPS 1 B) (CNDDB Occurrence # 3): This occurrence is reported to be due east of the corner of 5th Ave. and Poppy Ave. in Buck Gully in an area of chaparral R:Projects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3—U December8, 2003

and coastal sage scrub. Four to seven plants were observed in 1991, and this occurrence is presumed to still be present.
• Lasthenia glabrata (Coulter's goldfields) (CNPS 1 B) (CNDDB Occurrence # 58): Location information for this occurrence is "Buck Gully, about one mile upstream from Highway 1." Two plants were observed in 1998 in a clay depression near willow woodland in the valley bottom. This occurrence is presumed to still be present.

Waters/Wetlands of the U.S.

The unnamed creek channel flowing the length of Buck Gully is a likely water of the U.S. Sections of the riparian corridor and the coastal freshwater marsh at the mouth of the canyon near Little Corona Beach may also be considered "associated wetlands."
Integrity
The lower (western) portion of Buck Gully is isolated from the upper Buck Gully by the Coast Highway. This area is closely confined by residential development on the south and north. The proximity to development, accessibility by local residents and their pets, and abundance of non-native ornamental plant species detract from the quality of habitat for wildlife species in this area. The upper (eastern) portion of Buck Gully is a broad, open, relatively undisturbed canyon. Coastal sage scrub and mixed chaparral dominate much of the area, except for the riparian corridor along the canyon bottom and the tops of the canyon, which are influenced by the adjacent residential development. Much of the native vegetation near the rim of the canyon has been removed to reduce wildfire hazard.

Ornamental and non-native plant species from the adjacent residential development have encroached into Buck Gully, especially in the lower, narrow portions. Annual grasslands in Buck Gully consist of non-native annual grasses and forbs. Some non-native inclusions were also observed in the Diegan coastal sage scrub, southern mixed chaparral, and southern willow scrub habitats.

3.1.3 Morning Canyon

3.1.3.1 Description
Morning Canyon, an 8.26-acre ESA perpendicular to the coastline, is located between Corona Highlands and Cameo Highlands above the Coast Highway, and between Shore Cliff and Cameo Shores on the ocean side of Coast Highway (Figure 9). Morning Canyon is bordered by the Pacific Ocean to the west, Pelican Hills Golf P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-9 December8, 2003

3. Biological Habitats
Course to the east, and residential development to the north and south. This ESA is located on the Laguna Beach 7.5 minute USGS topographic quadrangle.

Morning Canyon is characterized by disturbed, remnant, southern mixed chaparral vegetation on the canyon floor and along the upland slopes. This area, however, contains few remaining native species and is dominated by non-native and ornamental species that have invaded the canyon from adjacent residential areas located immediately to the northwest and southeast. Native plant species in the remnant southern mixed chaparral community include coyote brush, toyon, mountain mahogany (Cercopcarpus betuloides), lemonadeberry, and blue elderberry. Non-native species include fennel, pampas grass, acacia, date palm (Phoenix sp.), fig (Ficus sp.), hottentot fig (Carpobrotus edulis), Himalayan blackberry (Rubus discolor), tree tobacco, pittosporum (Pittosporum sp.), and castor bean.

The canyon bottom once supported a southern willow scrub and willows, mule fat, and mugwort (Artemisia douglasiana) can still be observed growing among the dominant non-native vegetation, though these species are no longer common enough to consider this habitat to be southern willow scrub. Non-native plant species now dominate the bottom and lower slopes of the canyon and include giant reed, acacia, hottentot fig, eucalyptus, myoporum, Mexican fan palm, Brazilian pepper tree, Peruvian pepper tree, pampas grass, ivy (Hedera sp.), and fennel.

Although most of the native riparian -associated species have been displaced by non-native and ornamental species, the area is still used by riparian wildlife, such as American crow (Corvus brachyrhyncus), northern mockingbird (Mimus polyglottos), mourning dove (Zenaida macroura), cedar waxwing (Bombycilla garrulous), English sparrow (Passer domesticus), raccoon (Procyon lotor), and opossum (Didelphis virginiana). The presence of a perennial watercourse along with a structurally diverse woody vegetation community provides the necessary habitat attributes that are essential to riparian -associated species.

Integrity
The lower, southwestern section of Morning Canyon is separated from the upper section of Morning Canyon by the Coast Highway. The entire canyon is very narrow and closely bordered by residential development on the northwest and southeast, the Pacific Ocean to the southwest, and the Pelican Hills Golf Course at the northeastern edge of the area. Ornamental species have completely displaced native vegetation in much of canyon and now dominate throughout the majority of this ESA. Pets from the adjacent residences likely use the area and further discourage wildlife use of the canyon.

3.1.4 MacArthur and San Miauel

3.1.4.1 Description
The 7.69-acre MacArthur and San Miguel ESA (Figure 7), consists of two relatively small and isolated patches of undeveloped land divided by San Miguel Drive, and bordered by Avocado Avenue to the northwest and MacArthur Boulevard to the southeast. The area south of San Miguel Drive is bordered by an open lot to the south (north of the Central Library), while the area north of San Miguel Drive is bordered by San Joaquin Hills Road to the northeast. The site is located on the USGS Newport Beach 7.5-minute topographic quadrangle.

The area south of San Miguel Drive is 3.54 acres of predominantly Diegan coastal sage scrub habitat, consisting of California sagebrush, deerbrush (Lotus scoparius), and coyote brush, along with the non-native tocalote and scattered instances of prickly pear. Other common, non-native species include black mustard and various grasses. The perimeter of this portion of the site has been previously disturbed by adjacent road development and several ornamental species occur immediately outside the boundaries of this area, including eucalyptus, myoporum, and Peruvian pepper tree. Much of the adjacent undeveloped land - particularly the large lot separating the site from the Central Library - supports ruderal vegetation.

Two drainages intersect in the middle of this parcel. An east -west flowing drainage supports a limited amount of disturbed southern willow scrub habitat containing willow, cattails, bulrush and mule fat. The north -south flowing drainage supports a small seasonal wetland consisting of cattail and duckweed (Lemna sp.) The area north of San Miguel Drive consists of 4.15 acres dominated by mowed annual grassland containing ripgut brome, wild oat, soft chess, Bermuda grass (Cyonodon dactylon), Bermuda buttercup (Oxalis pes- P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-12 December8, 2003

There are also some scattered coyote brush, California sagebrush, and saltbush (Atriplex sp.) shrubs typically associated with the coastal sage scrub that likely dominated the site prior to development. This area has been graded adjacent to MacArthur Boulevard, but then slopes steeply towards Avocado Avenue. A public transit center on the northern third of this parcel is bordered by ornamental (Mexican fan palm and pine) trees and turf grass, which also occur at the corner of MacArthur Boulevard and San Miguel Drive. Two concrete -lined ditches - one adjacent to Avocado Avenue and the other crossing the site near San Miguel Drive — drain the area.

Although suitable habitat exists for these species within the MacArthur/San Miguel ESA, the small, fragmented nature of the area and its proximity to development, makes it unlikely that most species would utilize this area.

Special -Status Species (Known Occurrences)
There are no recorded occurrences of special -status species in the CNDDB for the MacArthur/San Miguel ESA.

Waters/Wetlands of the U.S.

The two drainages traversing the parcel south of San Miguel Drive, along with the small seasonal wetland associated with the north -south flowing drainage, could be potential "waters of the U.S." The concrete -lined ditches north of San Miguel Drive are, however, not likely to be considered "waters of the U.S." Integrity
This ESA is relatively small in size (7.69 acres) and completely isolated from any adjacent, associated habitats by urban development, thereby precluding the use of this ESA by most wildlife species. This proximity to R:Projects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-14 December8, 2003

development has introduced numerous ornamental and non-native species to the perimeter of the site, further reducing the integrity of the ESA. The fact that the area north of San Miguel Drive is maintained in a mowed condition makes use of this area by wildlife highly unlikely.

3.1.5 Spyglass Hill

3.1.5.1 Description
The 17.31-acre Spyglass Hill ESA includes the uppermost reaches of Big Canyon (Figure 8). The site consists of a well-defined canyon with vegetated slopes bordered by residential development and a seasonal, southeast to northwest flowing drainage at the canyon bottom. This ESA is west of Spyglass Hill Road and northeast of Mission Bay Drive. The site is located on the USGS Newport Beach 7.5-minute topographic quadrangle.

This community is dominated by the Diegan coastal sage scrub and southern mixed chaparral, with several ornamental trees along the northeast -facing slope, just up from the vegetated canyon bottom. In addition, native vegetation immediately adjacent to the residential development has been cleared for fire prevention purposes.

The upland areas on the north and east slopes of the main drainage support dense Diegan coastal sage scrub habitat, dominated by California sagebrush, coyote brush, lemonadeberry, California buckwheat, deerweed, white sage, and laurel sumac. Slopes south and west of the drainage support southern mixed chaparral, dominated by toyon, ceanothus, coyote brush, bush mallow (Malacothamnus sp.), scrub oak, live oak (Quercus agrifolia), bush monkey flower, poison oak, blue elderberry, lemonadeberry, and chamise. The drainage itself is ephemeral and therefore is unable to support typical riparian habitat. It is characterized by species associated with the Diegan coastal sage scrub to the northeast and the southern mixed chaparral to the southwest.

Waters/Wetlands of the U.S.

The unnamed creek channel flowing the length of through this ESA is a potential waters of the U.S.

Integrity
The Spyglass Hill ESA is a relatively undisturbed area of high -quality Diegan coastal sage scrub and southern mixed chaparral. Except for the area immediately adjacent to the residential development to the west and southwest, the habitats in the Spyglass Hill ESA are almost entirely composed of native species. However, this ESA is completely isolated from any adjacent, associated habitats by residential development, and overall the area is relatively small (17.31 acres). This is an ideal example of fragmented habitat. While supporting undisturbed native vegetation communities, the isolated nature of the area possibly precludes its use by many wildlife species.

3.1.6 Coastal Foredunes

3.1.6.1 Description
Foredune habitats are identified by stands of dense to sparse annual and perennial herbs, grasses, or shrubs occurring on sand dunes along the coast. In Newport Beach, southern coastal foredune habitat extends southwest, from 10th Street to the tip of the Balboa peninsula along the ocean side of Balboa, immediately adjacent to the bike lane (Figures 4-6). The vegetation in this community is generally sparse with overall cover ranging from 20 to 70 percent in some areas, while other areas are completely devoid of vegetation. Areas of open sand fragment this southern coastal foredune habitat. Dominant plants include non-native species such as sea -fig, hottentot fig, sea rocket (Cakile maritima), and native purple sand -verbena (Abronia umbellata), beach evening primrose (Camissonia cheiranthifolia), beach morning glory (Calystegia soldanella), and beach P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-17 December8, 2003

3. Biological Habitats
bur (Ambrosia chamissonis). Many areas are almost completely covered by sea -fig and hottentot fig, which seem to have been introduced from the residences fronting the beach area. Although many areas within the Coastal Foredunes ESA have extensive non-native cover, these species are considered to be a component of southern coastal foredune habitat and were therefore not mapped differently from those areas supporting a predominance of native species.

This occurrence is presumed to still be present.

Waters/Wetlands of the U.S.

No potential wetlands/waters of the U.S. were observed during biological surveys within the Coastal Foredunes ESA.

Integrity
Ornamental and non-native species, likely introduced from the adjacent residences, dominate much of the southern coastal foredune habitat in this ESA. Numerous residences use the beach area as an extension of their backyards and residents have planted and irrigated the ornamental species that have replaced native species in these areas. Increased human activity and public access also adversely impact these dune habitats, as evidenced by the numerous trails bisecting the dunes.

3.1.7 Banning Ranch

3.1.7.1 Description
The 282.40-acre Banning Ranch ESA is located near the mouth of the Santa Ana River (Figures 13-14). This ESA is bordered to the northeast and east by residential and commercial development, to the north by Talbert Regional Park, to the south by West Coast Highway, and to the south and west by the Newport Shores residential community and the Semeniuk Slough ESA. The Banning Ranch site is located on the Newport Beach 7.5 minute USGS topographic quadrangle.

P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-19 December8, 2003

3. Biological Habitats
The Banning Ranch ESA encompasses four distinct topographic features that influence the type and character of biological resources on the site. The western edge of Newport Mesa, which comprises much of the eastern portion of the site, represents a coastal plane that slopes gently from east to west. Historic oil -extraction related infrastructure is found throughout the mesa, including the location of wells, pipelines, buildings, improved and unimproved roads, and open storage pipes and machinery.

Bluffs form the western edge of the mesa, which are very steep along the southern and southwestern edges of the mesa, but become less severe in the north. These bluffs provide a transition between mesa uplands to the east and the lowlands to the west.

The bluffs and mesa are incised at various points along their/its length by a number of drainages. Two of these drainage features - one in the southern portion of the site and one in the northern portion - are markedly larger than the others and referred to as "arroyos".

The majority of the lowlands in the western portion of the project site were historically tidal marsh associated with Semeniuk Slough. The construction of a levee between the Banning Ranch lowlands and Semeniuk Slough removed the former from tidal influence, very likely to facilitate oil extraction activities. Subsequent channelization of the Santa Ana River and oil extraction activities at Banning Ranch, dating back at least 75 years, have altered these lowlands area to where they are now characterized by narrow channels and low pockets of periodically -standing water in some areas. Tidal influence is presently limited to only 4.8 acres at the southwest corner of the lowlands. The entire area supports a network of roads, pipelines, oil derricks, and a few buildings.

Plant communities on the Banning Ranch property range from relatively undisturbed native to highly disturbed exotic populations. Upland (mesa) areas generally support southern coastal bluff scrub and non-native grassland, while the lowlands support riparian and wetland vegetation. Current plant communities include: (1) southern coastal bluff scrub; (2) sage scrub -grassland ecotone/sere; (3) annual grassland; (4) ruderal (uplands); (5) ruderal wetlands; (6) vernal pool; (7) alkali meadow; (8) southern coastal salt marsh; (9) coastal brackish marsh; (10) mulefat scrub; (11) southern black willow forest; (12) developed areas; (13) disturbed areas; and (14) ornamental vegetation (Figures 13-14).

Scattered portions of both upland and lowland areas of Banning Ranch contain ruderal vegetation dominated by non-native grasses and forbs. Plant species associated with this community include black mustard, wild radish (Raphanus sativus), pampas grass, fennel, and filaree (Eroidum sp.). The lowland portions of this ESA consist of ruderal wetlands, alkali meadows, southern coastal salt marsh, and coastal brackish marsh.

Ornamental vegetation occurs throughout the site, though primarily in the upland areas, and include hottentot- fig, myoporum, and eucalyptus.

The following special -status species have recorded CNDDB occurrences or other known occurrences within or adjacent to the Banning Ranch ESA:
• Centromadia parryi ssp. australis (southern tarplant) (CNPS 1B) (CNDDB Occurrence #64): This occurrence of southern tarplant is from the "south end of the Newport oil fields in disturbed areas adjacent to oil pipelines" and is mapped near the southwestern border of the Banning Ranch ESA near its boundary with the Semeniuk Slough ESA. More than 1000 plants were observed in 1998. It was also observed on Banning Ranch by PCR during surveys conducted in 2000 for the Draft Program Environmental Impact Report Newport Banning Ranch Local Coastal Program (PCR, 2000).

This population is presumed to still be present.
• Aphanisma blitoides (aphanisma) (CNPS 1 B) (CNDDB Occurrence # 23): The information for this occurrence is from a 1932 herbarium collection from "Costa Mesa, along base of sea cliffs" and was mapped along the bluff separating Banning Ranch from Highway 1 and Semeniuk Slough. Although this population is presumed to still be present, it has not been observed since 1932. • San Diego fairy shrimp (Branchinecta sandiegoensis) (FE) was documented by PCR during surveys conducted in February and March 2000 for the Draft Program Environmental Impact Report Newport Banning Ranch Local Coastal Program (PCR, 2000) from the vernal pool and a small depression immediately to the south.

3. Biological Habitats
• Coastal California gnatcatcher (Polioptila californica californica) (FT, CSC) has been observed primarily within coastal bluff scrub onsite during focused surveys from 1992 to 1998. 19 pairs were observed in 1992 and between 1993 and 1996, the number of observed pairs ranged from 16 to 29. 17 pairs were observed in 1997, and 19 pairs were observed in 1998 (PCR, 2000). • Coastal cactus wren (Campylorhynchus brunneicapillus) (CSC) Ten pairs were observed in 1997 and seven pairs were observed in 1998 (PCR, 2000).
• The following special -status species were observed either on -site or flying over the area during surveys conducted by PCR for the Draft Program Environmental Impact Report Newport Banning Ranch Local Coastal Program (PCR, 2000): California least tern, yellow warbler, Belding's savannah sparrow, southwestern willow flycatcher, northern harrier, Cooper's hawk, golden eagle, sharp - shinned hawk, white-tailed kite, and osprey. No further details about these observations were given.

Waters/Wetlands of the U.S.

A 1998 wetland delineation performed by PCR determined there were 57.5 acres of jurisdictional waters on Banning Ranch, including 57.15 acres of jurisdictional wetlands and 0.35 acre of unvegetated channels. The majority of these wetlands are in the lowland portion in the northwest part of the ESA, with other jurisdictional areas associated with four drainages originating at various locations on the upper portions of the site. In addition, one vernal pool was identified near the central portion of the site (PCR, 2000).

Integrity
The Banning Ranch ESA is a large, relatively undeveloped, but historically disturbed assemblage of diverse habitats that, together with the contiguous Semeniuk Slough ESA, provides wildlife with a significantly large, diverse area for foraging, shelter, and movement. Infrastructure related to oil exploration and extraction is scattered throughout the area, especially in the northern portion of the mesa, degrading the native habitats where they occur. Much of the land surrounding developed areas (i.e. oil infrastructure) is disturbed and does not support any vegetation. Improved and unimproved roads bisect the entire ESA, fragmenting habitat and creating increased areas of "edge effect". Areas supporting annual grassland and ruderal vegetation communities are dominated by non-native species, typically annual grasses and forbs. Ornamental species are found throughout the site, primarily in upland areas. The entire Banning Ranch ESA is closed to public access, though pets from nearby residences and feral domestic animals are common transients through these habitats.

P:IProjects-All EmployeesM579-02Newport Beach BiolAddendumladdendum.doc3-24 December8, 2003

3. Biological Habitats
While disturbance associated with the oil infrastructure does diminish the quality of habitat in the Banning Ranch ESA to some extent, the overall area should be regarded as relatively high -quality wildlife habitat due to its large size, habitat diversity, and continuity with the adjacent Semeniuk Slough ESA.

3.2 SUMMARY
The information in this report is presented as a supplement to the City of Newport Beach, California, Local Coastal Plan — Biological Appendix (Chambers Group and Coastal Resources Management, December 2002) and the City of Newport Beach, California, General Plan — Newport Beach Biological Resources (Chambers Group and Coastal Resources Management, January 2003). Together with the ESA maps provided in Figures 2-14, this information can facilitate the decision -making process associated with any proposed development in these areas. This will guide the City in focusing development in areas with the fewest impacts to biological resources and attempting preservation and protection in areas with the highest biological value. The habitat value ranking system presented in this report will also guide resource permitting efforts of prospective developers by indicating which sub -areas of the studied ESAs either definitely will require some level of permitting or for which additional studies need to be performed to determine whether such permitting is required.

CITY OF NEWPORT BEACH

GENERAL PLAN TRANSPORTATION STUDY
ES.0 EXECUTIVE SUMMARY
This Executive Summary concisely summarizes all of the information in the Newport Beach General Plan Transportation Study (Urban Crossroads, Inc., March, 2006). For full details, the reader should also review the main body of the report. This report summarizes the Existing conditions and buildout alternatives traffic analysis completed for the City of Newport Beach General Plan update. Existing conditions are described and two General Plan buildout alternatives are evaluated: Without Project (buildout of existing General Plan) and With Project (buildout of proposed General Plan) conditions.

The buildout alternatives are analyzed using a roadway system that incorporates the constrained roadway network (with only those improvements from the currently adopted General Plan Circulation Element that have not been deemed "uncertain"), with the addition of the 19th Street bridge over the Santa Ana River, and the widening of Coast Highway through Mariner's Mile. Alternative modes of transport are also discussed in the report.

ES.1 Trip Generation
Trip generation is the initial step in determining future traffic conditions. Trip distribution (where people are going) and traffic assignment (what route, what time of day, and even what direction people are going) are equally important parts of the traffic forecasting process.

The potentially beneficial effects achieved through improved mixes of complimentary land use leads to the true measure of future traffic volumes and, most importantly, intersection peak hour operations. As demonstrated in subsequent sections of this report, the slightly increased trip generation for the ES-1

With Project scenario compared to the Without Project (currently adopted General Plan) scenario actually results in a decrease in the number of projected intersection deficiencies with no improvements to the roadway system) and a reduced list of the needed roadway improvements.

Trip generation calculations have been performed for existing, Without Project, and With Project scenarios. Tables ES-1 through ES-3 summarize the results of this analysis for daily, AM peak hour, and PM peak hour conditions, respectively.

Citywide trip generation for the Without Project scenario is projected to increase by 27%. For the With Project scenario, trip generation is expected to increase by 31 %, a difference of 4%. Existing represents 2002 conditions, consistent with the rest of the Environmental Impact Report. Existing differs slightly from previously published reports as the data sets continue to be reviewed, refined, updated, and generally improved. Increased trip generation / volume may not necessarily increase congestion. The effects are dependent on many other factors, including peaking characteristics of traffic, directional split, even quantity of cross -street traffic.

Trip generation rates were derived during the Newport Beach Traffic Model update to reflect conditions in Newport Beach. In Coastal areas, residential uses were found to generate less traffic than in other areas of the City. Daily Coastal trip generation is approximately 85 to 87% of trip generation in the majority of the City. Therefore, an adjustment of approximately 12 to 15% was made in trip generation for land uses in this area as part of the traffic model validation and is reflected in the General Plan Transportation Study.

The analysis documented herein is a series of steps that lead, ultimately, to the real meaning: How does the system work during peak traffic hours, with the recommended / planned improvements?
This is the real measure of performance, not changes in trip generation or traffic volumes.
